Symmetries, Information and Monster Groups before and after the Big Bang

2016-12-01

Full Text Available The Monster group, the biggest of the sporadic groups, is equipped with the highest known number of dimensions and symmetries. Taking into account variants of the Borsuk–Ulam theorem and a novel topological approach cast in a physical fashion that has the potential to be operationalized, the universe can be conceived as a lower-dimensional manifold encompassed in the Monster group. Our universe might arise from spontaneous dimension decrease and symmetry breaking that occur inside the very structure of the Monster Module. We elucidate how the energetic loss caused by projection from higher to lower dimensions and by the Monster group’s non-abelian features is correlated with the present-day asymmetry in the thermodynamic arrow. By linking the Monster Module to its theoretical physical counterparts, it is then possible to calculate its enthalpy and Lie group trajectories. Our approach also reveals how a symmetry break might lead to a universe based on multi-dimensional string theories and CFT/AdS (anti-de Sitter/conformal field theory correspondence.

Horror fiction is a thriving industry. Many consumers pay hard-earned money to be scared witless by films, books, and computer games. The well-told horror story can affect even the most obstinate skeptic. How and why does horror fiction work? Why are people so fascinated with monsters? Why do hor....... An exhaustive, vertically integrated theory of horror fiction incorporates the cultural dimension.

Conserving Space Heritage - The Case for Tranquillity Base

Science.gov (United States)

Fewer, G.

One of the most important and spectacular events in the history of space exploration was the first Moon Landing of 1969. Safe from the ravages of erosion, agriculture, industry or the expansion of human settlement, the greatest threat to the site of this momentous event - Tranquillity Base - is likely to be from a meteor impact. However, with the advent of space tourism and commercial space travel, the site of humankind's first visit to a celestial body may come under threat of a different kind - that of souvenir hunters and miners. In this paper, the historical background to the Apollo programme is outlined and the sequence of events that made up the Apollo 11 mission, which conducted the first Moon landing, is described before concluding with a consideration of the heritage conservation issues of Tranquillity Base.

Mary Shelley's Frankenstein: what made the Monster monstrous?

Science.gov (United States)

Britton, Ronald

2015-02-01

This paper discusses the genesis of the famous story of Frankenstein which arose from a dream experienced by Mary Shelley whilst on a holiday shared with her husband Percy Shelley, Lord Byron, Dr Polidori and her step sister Claire Clairmont. The novel relates how the creature created by Victor Frankenstein horrifies him, is rejected by him and called a monster. The monster's ensuing despair and subsequent murderousness is eloquently described. The whole book is clearly connected to Mary Shelley's experience as an infant whose mother died after giving birth to her and her subsequent loss, as a mother, of her own new born infant. It is suggested that the novel imaginatively describes what it is to have been primarily rejected as an infant and to feel regarded as a monster. © 2015, The Society of Analytical Psychology.

[The monster and the city].

Science.gov (United States)

Calvo Albizu, A

1996-01-01

"Negative aesthetic categories" and, specifically, the idea of monsters and monstrosity, are used in this discussion of urban phenomena and their relation to modern art. The reflection on monstrosity as a metaphor for the city draws upon such disparate sources as Greek philosophers, Freudian theory, and recent art criticism. It compares dictionary definitions of monster to a general concept of cities, judging the modern metropolis to be "excessively large or extraordinary," "disfigured and ugly," and even "cruel" and "perverse" as demonstrated in social pathologies such as terrorism that breed in cities. The relationship between monstrosity and the city is evident in a variety of artistic manifestations and can be seen in the work of planners, architects, and artists. The examination opens up promising areas for future research in greater depth.

Formulation and quality control of a poly herbal tranquilizer syrup

Directory of Open Access Journals (Sweden)

2017-11-01

Full Text Available Background and objectives: Herbal drugs are rapidly becoming popular in recent years as alternative therapies. Numerous poly herbal formulations, which are combinations of different herbal materials/extracts are being used for prevention or treatment of various disorders. The present research has been undertaken to formulate and evaluate the quality of a tranquilizing syrup based on Iranian traditional medicine references. Methods: A decoction containing Echium amoenum L., Lavandula spp. L., Melissa officinalis L., Cuscuta chinensis Lam, Vitis venifera L.,Prunus domestica and Alhagi camelorum Fisch.was prepared and then filtered. The filtrate was concentrated and different sweeteners and flavoring agents including, brown sugar, honey, masking flavor, sucralose, lemon and orange essential oil were examined to cover the unpleasant taste of the product caused by Cuscuta chinensis. Finally,sucralose was found to be beneficent to cover the unpleasant taste. The final product was evaluated physicochemically and microbiologically according to standard protocols. Results: The results of the quality control assessments demonstrated that the color, odor, microbial and physicochemical characteristics of the syrup were acceptable. Conclusion: The formulated syrup can be examined in in vivo and clinical studies as a tranquilizer with respect to its tranquilizing herbal content.

The Personal Viewpoint on the Meaning of Tranquility Affects the Appraisal of the Urban Park Soundscape

Directory of Open Access Journals (Sweden)

Karlo Filipan

2017-01-01

Full Text Available Previous research has shown that tranquil areas in the city, such as urban parks, are usually perceived as positive and have a restorative effect on visitors. However, visitors could experience these spaces differently depending on the meaning they assign to the concept of tranquility. To investigate how individuals’ personal views on tranquility affect their perception of the sonic environment, a soundscape study was conducted in several city parks in Antwerp, Belgium. Mobile sound measurements were combined with a questionnaire survey amongst 660 park visitors. Within the survey, the participants’ viewpoint on tranquility was evaluated using their agreement with a set of previously established prototypical statements, categorizing them into one out of three main tranquility viewpoint groups: people that associate tranquility with silence, those that associate it with hearing natural sounds, or those that associate it with social relationships. Next to this, the sounds that participants had heard during their visit were noted, and their perception of the overall quality of the soundscape and the degree to which it matched their expectation were assessed. Results show that the park visitors who associate tranquility with natural sounds or to silence are more often found amongst those that report hearing mechanical sounds a lot. The same groups of visitors rate the overall quality of the sonic environment of the park more often bad to very bad. These findings suggest that park visitors pay attention more to the sounds they do not expect to hear, and that the higher their expectations about the soundscape, the more critical they become in their appraisal of the soundscape.

Introduction to vertex algebras, Borcherds algebras and the Monster Lie algebras

International Nuclear Information System (INIS)

Gebert, R.W.

1993-09-01

The theory of vertex algebras constitutes a mathematically rigorous axiomatic formulation of the algebraic origins of conformal field theory. In this context Borcherds algebras arise as certain ''physical'' subspaces of vertex algebras. The aim of this review is to give a pedagogical introduction into this rapidly-developing area of mathematics. Based on the machinery of formal calculus we present the axiomatic definition of vertex algebras. We discuss the connection with conformal field theory by deriving important implications of these axioms. In particular, many explicit calculations are presented to stress the eminent role of the Jacobi identity axiom for vertex algebras. As a class of concrete examples the vertex algebras associated with even lattices are constructed and it is shown in detail how affine Lie algebras and the fake Monster Lie algebra naturally appear. This leads us to the abstract definition of Borcherds algebras as generalized Kac-Moody algebras and their basic properties. Finally, the results about the simplest generic Borcherds algebras are analysed from the point of view of symmetry in quantum theory and the construction of the Monster Lie algebra is sketched.

This article is inspired by empirical philosophy and provides an analysis of economic growth as a monster that circulates within collectives. Using this approach, I illustrate how economic growth has participated in shaping institutions and language, thus having necessitated its own circulation...... to such an extent that it has become the most prioritised economic policy objective, whereas urgent issues regarding living conditions on Earth are either ignored or treated as secondary priorities. Further, I argue that noble attempts to contest economic growth contribute to the circulation of the monster...

Baba Yaga, Monsters of the Week, and Pop Culture’s Formation of Wonder and Families through Monstrosity

Directory of Open Access Journals (Sweden)

Jill Terry Rudy

2016-06-01

Full Text Available This paper considers transforming forms and their purposes in the popular culture trope of the televised Monster of the Week (MOTW. In the rare televised appearances outside of Slavic nations, Baba Yaga tends to show up in MOTW episodes. While some MOTW are contemporary inventions, many, like Baba Yaga, are mythological and fantastic creatures from folk narratives. Employing the concept of the folkloresque, we explore how contemporary audiovisual tropes gain integrity and traction by indexing traditional knowledge and belief systems. In the process, we examine key affordances of these forms involving the possibilities of wonder and the portability of tradition. Using digital humanities methods, we built a “monster typology” by scraping lists of folk creatures, mythological beasts, and other supernatural beings from online information sources, and we used topic modeling to investigate central concerns of MOTW series. Our findings indicate connections in these shows between crime, violence, family, and loss. The trope formulates wonder and families through folk narrative and monster forms and functions. We recognize Baba Yaga’s role as villain in these episodes and acknowledge that these series also shift between episodic and serial narrative arcs involving close relationships between characters and among viewers and fans.

Leonardo Da Vinci, the genius and the monsters. Casual encounters?

Science.gov (United States)

Ciseri, Lorenzo Montemagno

2014-01-01

This article analyses Leonardo's interest in monsters and deformed reality, one of the lesser known aspects of his vast and multifaceted output. With the possible exception of his studies of physiognomy, relevant drawings, sketches and short stories represent a marginal aspect of his work, but they are nevertheless significant for historians of teratology. The purpose of this study is to provide a broad overview of the relationship between Leonardo and both the literature on mythological monsters and the reports on monstrous births that he either read about or witnessed personally. While aspects of his appreciation and attention to beauty and the pursuit of perfection and good proportions are the elements most emphasised in Leonardo's work, other no less interesting aspects related to deformity have been considered of marginal importance. My analysis will demonstrate that Leonardo approached the realm of monstrosity as if he considered abnormality a mirror of normality, deformity a mirror of harmony, and disease a mirror of health, as if to emphasise that, ultimately, it is the monster that gives the world the gift of normality. Two special cases of monstrosity are analysed: the famous monster of Ravenna, whose image was found among his papers, and a very rare case of parasitic conjoined twins (thoracopagus parasiticus) portrayed for the first time alive, probably in Florence, by Leonardo himself.

The monstering of tamarisk: how scientists made a plant into a problem.

Science.gov (United States)

Chew, Matthew K

2009-01-01

Dispersal of biota by humans is a hallmark of civilization, but the results are often unforeseen and sometimes costly. Like kudzu vine in the American South, some examples become the stuff of regional folklore. In recent decades, "invasion biology," conservation-motivated scientists and their allies have focused largely on the most negative outcomes and often promoted the perception that introduced species are monsters. However, cases of monstering by scientists preceded the rise of popular environmentalism. The story of tamarisk (Tamarix spp.), flowering trees and shrubs imported to New England sometime before 1818, provides an example of scientific "monstering" and shows how slaying the monster, rather than allaying its impacts, became a goal in itself. Tamarisks' drought and salt tolerance suggested usefulness for both coastal and inland erosion control, and politicians as well as academic and agency scientists promoted planting them in the southern Great Plains and Southwest. But when erosion control efforts in Arizona, New Mexico and Texas became entangled with water shortages, economic development during the Depression and copper mining for national defense during World War Two, federal hydrologists moved quickly to recast tamarisks as water-wasting foreign monsters. Demonstrating significant water salvage was difficult and became subsidiary to focusing on ways to eradicate the plants, and a federal interagency effort devoted specifically to the latter purpose was organized and continued until it, in turn, conflicted with regional environmental concerns in the late 1960s.

Tranquilizing and Allaying Excitement Needling Method Affects BDNF and SYP Expression in Hippocampus

Directory of Open Access Journals (Sweden)

Peng Zheng

2017-01-01

Full Text Available Sleep disorder is a state of sleep loss caused by various reasons, which leads to a series of changes, such as emotion, learning and memory, and immune function. “Tranquilizing and allaying excitement” was widely used in clinical treatment of insomnia; however, the mechanism was still not very clear. We randomly divided rats into three groups: control group, sleep deprivation group, and acupuncture treatment group. We observed BDNF and SYP expression in hippocampus in these three groups. Both protein contents and mRNA contents of BDNF and SYP were measured by western blot, immunohistochemistry, and RT-PCR analysis. The sleep deprivation model was established using modified multiple platform sleep deprivation method (MMPM. Our study explored the BDNF and SYP abnormality in hippocampus caused by sleep deprivation and “tranquilizing and allaying excitement” intervention regulated the abnormal expression of BDNF and SYP caused by sleep deprivation on the short run and the long run. Our study provided a molecular evidence that “tranquilizing and allaying excitement” treatment in rats with sleep disorder affects learning and memory ability.

Does urbanization influence the spatial ecology of Gila monsters in the Sonoran Desert?

Science.gov (United States)

Kwiatkowski, M.A.; Schuett, G.W.; Repp, R.A.; Nowak, E.M.; Sullivan, B.K.

2008-01-01

To assess whether urbanization influences the spatial ecology of a rare and protected venomous reptilian predator, the Gila monster Heloderma suspectum, we compared home range (HR) size and movement parameters at three sites varying in degree of urbanization in the Sonoran Desert. We predicted that the urban population of H. suspectum would exhibit smaller HRs, avoid human structures and show less movement. Multivariate analysis indicated that males generally exhibited larger HRs and had higher movement rates and activity levels than females at all three sites. Contrary to our predictions, however, HR size and movement parameters did not vary across the sites in relation to the level of urbanization. At the urban site, individuals often crossed narrow roads and regularly used artificial structures as refuges for extended periods. Furthermore, the population sex ratio at the urban site was female-biased, consistent with the expectation that occupation of larger HRs and higher movement rates results in higher mortality for males in urbanized areas. Gila monsters did not appear to alter certain aspects of their spatial ecology in response to low levels of human activity but additional work will be required to assess population viability and possible effects in the long term and with higher levels of urbanization.

Differential bilingual laterality: mythical monster found in Wales.

Evans, Judith; Workman, Lance; Mayer, Peter; Crowley, Kevin

2002-11-01

Paradis (1992) likens studies of bilingual laterality to reported sightings of the Loch Ness Monster, in that although some studies claim differential laterality much conflicting research evidence does not-and like the mythical Scottish monster, what reason have we to suspect that any such phenomenon might exist? This study reexamines differential bilingual laterality using four groups of English-Welsh bilinguals which differ in their age of acquisition and in their environment of acquisition. Using a split visual field paradigm we present evidence which, supports the notion of greater right hemisphere processing in a later learned language. Our findings also suggest the pattern of lateralization in bilinguals is strongly affected by the specific language environment during development such that the shift toward greater right hemisphere involvement for the later learned language will be more pronounced in individuals which are brought up in areas where that language is not regularly heard.

Considering Freudian and Post-Freudian approaches to the intersubjective Beatrice Ithier puts the work of Michel de M'Uzan and Thomas Ogden in comparison. To this comparison I add a consideration of the work of Christopher Bollas. The highly creative clinical approaches these three theorists take is shown to be informed by their elaborations of the Freudian notion of unconscious communication and by new approaches to the issue of identity. Attention is paid to differentiating traumatic from fanciful chimeras; and to the experience of the analyst undergoing the sorts of transformations requisite to entering this psychic space marked by fluid exchanges of being and becoming, wherein analyst becomes patient, new subjects are created through shared dreams, and through which monsters appear.

Future Challenges of Robotics and Artificial Intelligence in Nursing: What Can We Learn from Monsters in Popular Culture?

Science.gov (United States)

Erikson, Henrik; Salzmann-Erikson, Martin

It is highly likely that artificial intelligence (AI) will be implemented in nursing robotics in various forms, both in medical and surgical robotic instruments, but also as different types of droids and humanoids, physical reinforcements, and also animal/pet robots. Exploring and discussing AI and robotics in nursing and health care before these tools become commonplace is of great importance. We propose that monsters in popular culture might be studied with the hope of learning about situations and relationships that generate empathic capacities in their monstrous existences. The aim of the article is to introduce the theoretical framework and assumptions behind this idea. Both robots and monsters are posthuman creations. The knowledge we present here gives ideas about how nursing science can address the postmodern, technologic, and global world to come. Monsters therefore serve as an entrance to explore technologic innovations such as AI. Analyzing when and why monsters step out of character can provide important insights into the conceptualization of caring and nursing as a science, which is important for discussing these empathic protocols, as well as more general insight into human knowledge. The relationship between caring, monsters, robotics, and AI is not as farfetched as it might seem at first glance.

But, in the hands of the large generators, co-firing is a potential monster, capable of destroying the carefully-constructed incentive structure for 'real' renewables such as wind power and dedicated biomass plants. Both views contain an element of truth, but the conflict between them could endanger the infant energy crop industry. 1 fig., 2 photos.

The purpose of this pilot study was to establish the feasibility of completing a future controlled trial of a multi-component cognitive behavioral therapy for insomnia program for military veterans with sleep disturbance. This was a single-arm feasibility and pilot study. Participants were United States post-9/11 veterans with service-connected injuries, university students, and had self-reported sleep disturbances. Restoring Effective Sleep Tranquility was a multi-component cognitive behavioral therapy for insomnia intervention consisting of seven sessions of group therapy and eight 1:1 sessions delivered by occupational therapists. Feasibility and pilot indicators were process, resources, management, and scientific, including pre-post-assessments of sleep difficulties, dysfunctional sleep beliefs, participation, and pain interference. Indicators were supportive of feasibility, including reduced sleep difficulties (for example Medical Outcomes Study Sleep Measure [ t  = 3.29, p  = .02]), reduced nightmares: t  = 2.79, p  = .03; fewer dysfunctional sleep beliefs: t  = 3.63, p  = .01, and greater ability to participate in social roles: t  = -2.86, p  = .03, along with trends towards improved satisfaction with participation and reduced pain interference. The Restoring Effective Sleep Tranquility program may reduce sleep difficulties and improve participation in US veterans with service-connected injuries, and evidence indicates a controlled trial would be feasible to deliver.

Taming the monsters of tomorrow

In Mary Shelley's novel, the scientist Victor Frankenstein fears that creating a female companion to his unhappy monster could lead to a "race of devils" that could drive humanity extinct. Today, some scientists worry about scientific advances in the real world that could kill all of humanity, or at least end civilization as we know it. Some two dozen researchers at three academic centers are studying these "existential risks"—including labmade viruses, armies of nanobots, and artificial intelligence—and what can be done about them. But critics say their scenarios are far-fetched and distract from real existential dangers, including climate change and nuclear war.

The monster within: Mary Shelley's Frankenstein and a patient's fears of childbirth and mothering.

Science.gov (United States)

Almond, B R

1998-08-01

This paper explores the fantasy, widespread among women, of giving birth to a monster, particularly a psychological monster. The author hypothesises two central intrapsychic issues underlying these fears: monsters are viewed as 'incest babies' or as reflections of maternal aggression--evil, destructive parts of the mother passed on to the infant. Shame about femaleness is postulated as a third factor in the fear of producing something monstrous. Mary Shelley's novel, 'Frankenstein', is an iconic literary representation of these themes. The author presents and discusses some psychobiographical material about Mary Shelley, speculating on her motives for writing this novel and tracing the intrapsychic concerns about incest and aggression as reflected in the novel itself. Some recent feminist and psychoanalytic critical readings of 'Frankenstein' are referenced as they reflect on the novel's concern with themes of female sexuality and procreation. Clinical material from the author's own practice is presented to illustrate these fears, so similar to those with which Mary Shelley was dealing. A discussion, citing some relevant literature, follows.

A set of scientific theories and an effective acupuncture therapy for insomnia about "the needling method for tranquillization and calming the mind" are gradually formed through many years' theoretical and clinical studies. In this paper, the theoretical intention about "the needling method for tranquillization and calming the mind" for treatment of insomnia are briefly introduced mainly from the cause of disease,pathogenesis, therapeutic method and characteristics of composition of a prescription, etc. in order to provide a new train of thoughts and a new method for working out scientific and standard prescriptions in the treatment of insomnia.

Tarasca: ritual monster of Spain.

Science.gov (United States)

Gilmore, David D

2008-09-01

Let us now revisit our original assumptions. First, we note that for the participants in Hacinas Carnival the Tarasca is a figure of fun and joy, but it also exudes a strain of aggressive misogyny that many female residents, not to mention tourists, find somewhat unsettling. In the spirit of feminist currents in Spain, a group of young women protested in 1992 to town officials and, when rebuffed, sought to build their own female monster, which they intended to use to attack boys and men. While their plan was never carried out, and indeed met with stiff opposition from officialdom and, especially, from older women, some of the younger, more modern girls find the Tarasca appalling, and they told me so without compunction. Accordingly, today the festival tends to polarize the sexes as well as the generations. Also, many children are frightened by the gigantic mock-up with its snapping teeth and foul breath, and many of them burst into tears at the roaring of the demons. But despite these negatives--or perhaps because of them--the Tarasca breaks down boundaries between things normally kept separate in the mind: humor and terror, man and beast, order and disorder, old and young, life and death, and so on. In so collapsing opposites, the Tarasca causes people to pause and to think about and question everyday reality in the non-Carnival universe. All these observations of course support the structural arguments of our four theorists above and in particular seem to corroborate Bloch's concept (1992) of the regenerative power of "rebounding violence." However, there are three specific features here that need psychological amplification beyond simply confirming the work of previous theorists. We must first note that like most grotesque fantasies, the Hacinas monster combines disparate organic "realities" into a bizarre and monstrous image that by its very oddness and the resulting "cognitive mismatch" captures people's attention and sparks the imagination, especially that of

The majority of pacemaker pocket or lead erosions are due to either mechanical erosion by the bulky pulse generator or secondary to pacemaker pocket infection. We describe an unusual case of delayed pacemaker lead erosion causing extrusion of a portion of the pacing lead, with separate entry and exit points, with the gap filled with new skin formation, simulating the "Loch Ness Monster", which was successfully managed conservatively by surgical reinsertion.

The monster sporadic group and a theory underlying superstring models

International Nuclear Information System (INIS)

Chapline, G.

1996-09-01

The pattern of duality symmetries acting on the states of compactified superstring models reinforces an earlier suggestion that the Monster sporadic group is a hidden symmetry for superstring models. This in turn points to a supersymmetric theory of self-dual and anti-self-dual K3 manifolds joined by Dirac strings and evolving in a 13 dimensional spacetime as the fundamental theory. In addition to the usual graviton and dilaton this theory contains matter-like degrees of freedom resembling the massless states of the heterotic string, thus providing a completely geometric interpretation for ordinary matter. 25 refs

The archetypical venomous lizard species are the helodermatids, the gila monsters (Heloderma suspectum) and the beaded lizards (Heloderma horridum). In the present study, the gila monster venom proteome was characterized using 2D-gel electrophoresis and tandem mass spectrometry-based de novo peptide sequencing followed by protein identification based on sequence homology. A total of 39 different proteins were identified out of the 58 selected spots that represent the major constituents of venom. Of these proteins, 19 have not previously been identified in helodermatid venom. The data showed that helodermatid venom is complex and that this complexity is caused by genetic isoforms and post-translational modifications including proteolytic processing. In addition, the venom proteome analysis revealed that the major constituents of the gila monster venom are kallikrein-like serine proteinases (EC 3.4.21) and phospholipase A2 (type III) enzymes (EC 3.1.1.4). A neuroendocrine convertase 1 homolog that most likely converts the proforms of the previously identified bioactive exendins into the mature and active forms was identified suggesting that these peptide toxins are secreted as proforms that are activated by proteolytic cleavage following secretion as opposed to being activated intracellularly. The presented global protein identification-analysis provides the first overview of the helodermatid venom composition. The helodermatid lizards are the classical venomous lizards, and the pharmacological potential of the venom from these species has been known for years; best illustrated by the identification of exendin-4, which is now used in the treatment of type 2 diabetes. Despite the potential, no global analyses of the protein components in the venom exist. A hindrance is the lack of a genome sequence because it prevents protein identification using a conventional approach where MS data are searched against predicted protein sequences based on the genome sequence

Yangyin Anshen Koufuye could obviously decrease the spontaneous activity of rats, effectively shorten the process of falling into sleep of normal rats which were injected pentobarbital sodium and prolong the sleeping time. The effect of sedation and hypnotism were the same as Zhaoren Anshen Koufuye. Yangyin Anshen Koufuye also could markedly reduce the serum tensity of T3, T4 of hyperthyroid rats, which equaled to TCM's deficiency of yin. It also could prevent the glycogen content of liver from decreasing, decrease heart rate, resist weight losing, thus to show the effect of nourishing Yin and tranquilizing.

New and previously published observational data on galaxies with declination less than +82 deg from the Uppsala General Catalog (Nilson, 1973) are compiled in extensive tables and characterized in detail. Optical positions are confirmed by measurement of Palomar Sky Survey O prints, and radio identifications for 176 galaxies are made on the basis of 1.4-GHz Green Bank sky maps or 1.49-GHz observations obtained with the C configuration of the VLA in November-December 1986; contour maps based on the latter observations are provided. Radio-selected and IR-selected galaxy populations are found to be similar (and distinct from optically selected populations), and three radio/IR criteria are developed to distinguish galaxies powered by starbursts from those with supermassive black holes or other monster energy sources. 197 references

Research into snake venoms has revealed extensive variation at all taxonomic levels. Lizard venoms, however, have received scant research attention in general, and no studies of intraclade variation in lizard venom composition have been attempted to date. Despite their iconic status and proven usefulness in drug design and discovery, highly venomous helodermatid lizards (gila monsters and beaded lizards) have remained neglected by toxinological research. Proteomic comparisons of venoms of three helodermatid lizards in this study has unravelled an unusual similarity in venom-composition, despite the long evolutionary time (~30 million years) separating H. suspectum from the other two species included in this study (H. exasperatum and H. horridum). Moreover, several genes encoding the major helodermatid toxins appeared to be extremely well-conserved under the influence of negative selection (but with these results regarded as preliminary due to the scarcity of available sequences). While the feeding ecologies of all species of helodermatid lizard are broadly similar, there are significant morphological differences between species, which impact upon relative niche occupation.

2013-07-01

Like most natural product libraries animal venoms have long been recognized as potentially rich source of biologically active molecules with the potential to be mined for the discovery of drugs, drug leads and/or biosimilars. In this work we demonstrate as a proof of concept a novel approach to explore venoms for potential biosimilarity to other drugs based on their ability to alter the transcriptomes of test cell lines followed by informatic searches and Connectivity Mapping to match the action of the venom on the cell gene expression to that of other drugs in the Connectivity Map (C-Map) database. As our test animal venom we chose Heloderma suspectum venom (Gila monster) since exendin-4, a glucagon-like peptide 1 receptor agonist, isolated from the venom is currently on the market to treat type 2 diabetes. The action of Byetta(®) (exentide, synthetic exendin-4), was also used in transcriptome studies. Analysis of transcriptomes from cells treated with the venom or the drug showed similarities as well as differences. The former case was primarily attributed to the fact that Gila monster venom likely contains a variety of biologically active molecules that could alter the MCF7 cell transcriptome compared to that of the single perturbant Byetta(®). Using Ingenuity Pathway Analysis software, insulin-like growth factor 1 signaling was identified in the category of "Top Canonical Pathways" for both the venom and Byetta(®). In the category of "Top Molecules" up-regulated, both venom and Byetta(®) shared IL-8, cyclic AMP-dependent transcription factor 3 (ATF-3), neuron-derived orphan receptor 1 (NR4A3), dexamethasone-induced Ras-related protein 1 (RASD1) and early growth response protein 1, (EGR-1) all with potential relevance in diabetes. Using Connectivity Mapping, Gila monster venom showed positive correlation with 1732 instances and negative correlation with 793 instances in the Connectivity database whereas Byetta(®) showed positive correlation with 1692

[Ion-dependency of the GABA-potentiating effects of benzodiazepine tranquilizers and harmane].

Science.gov (United States)

Abramets, I I; Komissarov, I V

1984-06-01

Experiments on an isolated spinal cord of 8-15-day-old rats have shown that one of the possible mechanisms of the GABA-potentiating action of the benzodiazepine tranquilizer, chlorodiazepoxide, may be a decrease in the intraneuronal concentration of Ca2+. This is evidenced by the enhancement of the GABA-potentiating action of chlorodiazepoxide under Ca2+ deficiency in the medium and in the presence of the blockers of the voltage-dependent Ca2+ ionic channels--Mn2+ and Co2+, and by the reduction of the effect in question under Ca2+ excess in the medium and in the presence of the K+ channels blockers--tetraethylammonium and 4-aminopyridine. The GABA-potentiating action of harmane is likely to be related to the blockade of the voltage-dependent K+ channels and elevation of the intracellular concentration of Ca2+.

Cloacal evaporative cooling: a previously undescribed means of increasing evaporative water loss at higher temperatures in a desert ectotherm, the Gila monster Heloderma suspectum.

The Gila monster Heloderma suspectum is an active forager in an environment that, at times, can be extremely hot and arid. Thus, Gila monsters face extreme thermostatic and hydrostatic demands. For a desert ectotherm routinely risking dehydration, evaporative water loss (EWL) is typically viewed as detrimental. Yet evaporation simultaneously dehydrates and cools an animal. We explored EWL in Gila monsters by measuring cutaneous, ventilatory and cloacal EWL at five ambient temperatures between 20.5 degrees C and 40 degrees C. Our results show that Gila monsters have high EWL rates relative to body mass. Cutaneous EWL underwent a consistent, temperature-dependent increase over the entire range of test temperatures (Q(10)=1.61, with EWL ranging from 0.378 to 0.954 mg g(-1) h(-1)). Ventilatory EWL did not show a significant temperature-dependent response, but ranged from 0.304 to 0.663 mg g(-1) h(-1). Cloacal EWL was extremely low and relatively constant between 20.5 degrees C and 35 degrees C, but rose dramatically above 35 degrees C (Q(10) >8.3 x 10(7), from 0.0008 at 35 degrees C to 7.30 mg g(-1) h(-1) at 40 degrees C). This steep rise in cloacal EWL coincided with an increasing suppression of body temperature relative to ambient temperature. Dehydration to 80% of initial body mass led to a delay in the onset and an attenuation of the dramatic increase in cloacal EWL. These results emphasize the potential value of EWL for thermoregulation in ectotherms and demonstrate for the first time the role of the cloaca in this process.

Water supplementation affects the behavioral and physiological ecology of Gila monsters (Heloderma suspectum) in the Sonoran Desert.

In desert species, seasonal peaks in animal activity often correspond with times of higher rainfall. However, the underlying reason for such seasonality can be hard to discern because the rainy season is often associated with shifts in temperature as well as water and food availability. We used a combination of the natural climate pattern of the Sonoran Desert and periodic water supplementation to determine the extent to which water intake influenced both the behavioral ecology and the physiological ecology of a long-lived desert lizard, the Gila monster (Heloderma suspectum) (Cope 1869). Water-supplemented lizards had lower plasma osmolality (i.e., were more hydrated) and maintained urinary bladder water reserves better during seasonal drought than did control lizards. During seasonal drought, water-supplemented lizards were surface active a significantly greater proportion of time than were controls. This increased surface activity can lead to greater food acquisition for supplemental Gila monsters because tail volume (an index of caudal lipid stores) was significantly greater in supplemented lizards compared with controls in one of the two study years.

The crash of monster sawteeth in Tore Supra ion cyclotron resonance heated plasmas is observed to trigger long-lived magneto hydrodynamic (MHD) activity, dominated by a (m = 3, n = 2) magnetic perturbation at the edge. This phenomenon is reminiscent of the triggering of neoclassical tearing modes, although in Tore Supra the MHD activity decays and eventually vanishes. It can be explained by the linear destabilization of the (3, 2) mode as the current sheet developed in the non-linear stage of the internal kink relaxation gets closer to q = 3/2. However, the lifetime of the (3, 2) island is longer than the period of linear instability. We find that the neoclassical drive is essential for explaining the observed lifetime and width of the island, although the overall dynamics is controlled by the relaxation of the current profile on a resistive time scale

Conformal field theory, triality and the Monster group

International Nuclear Information System (INIS)

Dolan, L.; Goddard, P.; Montague, P.

1990-01-01

From an even self-dual N-dimensional lattice, Λ, it is always possible to construct two (chiral) conformal field theories, an untwisted theory H (Λ), and a Z 2 -twisted theory H (Λ), constructed using the reflection twist. (N must be a multiple of 8 and the theories are modular invariant if it is a multiple of 24.) Similarly, from a doubly-even self-dual binary code C, it is possible to construct two even self-dual lattices, an untwisted one Λ C and a twisted one anti Λ C . It is shown that H(Λ C ) always has a triality structure, and that this triality induces first an isomorphism H(anti Λ C )≅H(Λ C ) and, through this, a triality of H(anti Λ C ). In the case where C is the Golay code, anti Λ C is the Leech lattice and the induced triality is the extra symmetry necessary to generate the Monster group from (an extension of) Conway's group. Thus it is demonstrated that triality is a generic symmetry. The induced isomorphism accounts for all 9 of the coincidences between the 48 conformal field theories H(Λ) and H(Λ) with N=24. (orig.)

Ostomy significantly alters one's elimination pattern and can affect the individual in physiological, psychosocial and spiritual aspects. Over time, the ostomy patient's experience changes and they develop coping strategies to handle the new reality. The aims of this study sought Iranian ostomy patients' main problem, how they deal and the outcome of their efforts to manage that problem in their daily lives. A qualitative content analysis was conducted involving twenty-seven ostomy patients that were chosen by purposeful sampling and referred to the Iranian Ostomy Association from October 2015 to June 2016. The mean age of the participants was 55 years, 15 were males, the major cause of ostomy was colorectal cancer and the colostomy was the most common type of ostomy, and nineteen of them between one and twenty years lived with an ostomy. Most of them were married, had bachelor degree and received adjuvant therapy, and few were employed. Guarantee indecisive to maintain a stable life with an ostomy and the possibility of ostomy disclosure unpredictability show relative tranquility in patients' social life. Because of the ostomy nature, there is not the possibility of full control over life with an ostomy and this issue is causing concerns in their family and social life.

From Mathematical Monsters to Generalized Scale Invariance in Geophysics: Highlights of the Multifractal Saga

Science.gov (United States)

Schertzer, D. J.; Tchiguirinskaia, I.; Lovejoy, S.

2013-12-01

Fractals and multifractals are very illustrative of the profound synergies between mathematics and geophysics. The book ';Fractal Geometry of Nature' (Mandelbrot, 1982) brilliantly demonstrated the genericity in geophysics of geometric forms like Cantor set, Peano curve and Koch snowflake, which were once considered as mathematical monsters. However, to tame the geophysical monsters (e.g. extreme weather, floods, earthquakes), it was required to go beyond geometry and a unique fractal dimension. The concept of multifractal was coined in the course of rather theoretical debates on intermittency in hydrodynamic turbulence, sometimes with direct links to atmospheric dynamics. The latter required a generalized notion of scale in order to deal both with scale symmetries and strong anisotropies (e.g. time vs. space, vertical vs. horizontal). It was thus possible to show that the consequences of intermittency are of first order, not just 'corrections' with respect to the classical non-intermittent modeling. This was in fact a radical paradigm shift for geophysics: the extreme variability of geophysical fields over wide ranges of scale, which had long been so often acknowledged and deplored, suddenly became handy. Recent illustrations are the possibility to track down in large date sets the Higgs boson of intermittence, i.e. a first order multifractal phase transition leading to self-organized criticality, and to simulate intermittent vector fields with the help of Lie cascades, based for instance on random Clifford algebra. It is rather significant that this revolution is no longer limited to fundamental and theoretical problems of geophysics, but now touches many applications including environmental management, in particular for urban management and resilience. These applications are particularly stimulating when taken in their full complexity.

Mast cell degranulation is important in the pathogenesis of anaphylaxis and allergic disorders. Many animal venoms contain components that can induce mast cell degranulation, and this has been thought to contribute to the pathology and mortality caused by envenomation. However, we recently reported evidence that mast cells can enhance the resistance of mice to the venoms of certain snakes and that mouse mast cell–derived carboxypeptidase A3 (CPA3) can contribute to this effect. Here, we investigated whether mast cells can enhance resistance to the venom of the Gila monster, a toxic component of that venom (helodermin), and the structurally similar mammalian peptide, vasoactive intestinal polypeptide (VIP). Using 2 types of mast cell–deficient mice, as well as mice selectively lacking CPA3 activity or the chymase mouse mast cell protease-4 (MCPT4), we found that mast cells and MCPT4, which can degrade helodermin, can enhance host resistance to the toxicity of Gila monster venom. Mast cells and MCPT4 also can limit the toxicity associated with high concentrations of VIP and can reduce the morbidity and mortality induced by venoms from 2 species of scorpions. Our findings support the notion that mast cells can enhance innate defense by degradation of diverse animal toxins and that release of MCPT4, in addition to CPA3, can contribute to this mast cell function.

The majority of children in North America are not meeting current physical activity guidelines. The purpose of this study was to evaluate the impact of a mobile phone game ("MobileKids Monster Manor") as a tool to promote voluntary physical activity among children. The game integrates data from an accelerometer-based activity monitor (Tractivity(®); Kineteks Corp., Vancouver, BC, Canada) wirelessly connected to a phone and was developed with the involvement of a team of young advisors (KidsCan Initiative: Involving Youth as Ambassadors for Research). Fifty-four children 8-13 years old completed a week of baseline data collection by wearing an accelerometer but receiving no feedback about their activity levels. The 54 children were then sequentially assigned to two groups: One group played "MobileKids Monster Manor," and the other received daily activity feedback (steps and active minutes) via an online program. The physical activity (baseline and intervention weeks) was measured using the activity monitor and compared using two-way repeated-measures analysis of variance (intervention×time). Forty-seven children with a body mass index (BMI) z-score of 0.35±1.18 successfully completed the study. Significant (P=0.01) increases in physical activity were observed during the intervention week in both the game and feedback groups (1191 and 796 steps/day, respectively). In the game group, greater physical activity was demonstrated in children with higher BMI z-score, showing 964 steps/day more per BMI z-score unit (P=0.03; 95 percent confidence interval of 98 to 1829). Further investigation is required to confirm that our game design promotes physical activity.

Rb-Sr and Sm-Nd chronology and genealogy of mare basalts from the Sea of Tranquility

Rb-Sr and Sm-Nd ages of two Apollo 11 mare basalts, high-K basalt 10072 and low-K basalt 10062, are reported. Rb-Sr, Sm-Nd, and Ar-40-Ar-39 ages are in good agreement and indicate an extensive time interval for filling of the Sea of Tranquility, presumably by thin lava flows, in agreement with similar observations for the Ocean of Storms. Initial Sr and Nd isotopic compositions on Apollo 11 basalts reveal at least two parent sources producing basalts. The Sm-Nd isotopic data demonstrate that low-K and high-Ti basalts from Apollo 11 and 17 derived from distinct reservoirs, while low-Ti Apollo 15 mare basalt sources have Sm/Nd similar to the sources of Apollo 11 basalts. Groupings of mare basalt based on Ti content and on isotopic data do not coincide.

Problematic fossils, extinct taxa of enigmatic morphology that cannot be assigned to a known major group, were once a major issue in palaeontology. A long-favoured solution to the 'problem of the problematica', particularly the 'weird wonders' of the Cambrian Burgess Shale, was to consider them representatives of extinct phyla. A combination of new evidence and modern approaches to phylogenetic analysis has now resolved the affinities of most of these forms. Perhaps the most notable exception is Tullimonstrum gregarium, popularly known as the Tully monster, a large soft-bodied organism from the late Carboniferous Mazon Creek biota (approximately 309-307 million years ago) of Illinois, USA, which was designated the official state fossil of Illinois in 1989. Its phylogenetic position has remained uncertain and it has been compared with nemerteans, polychaetes, gastropods, conodonts, and the stem arthropod Opabinia. Here we review the morphology of Tullimonstrum based on an analysis of more than 1,200 specimens. We find that the anterior proboscis ends in a buccal apparatus containing teeth, the eyes project laterally on a long rigid bar, and the elongate segmented body bears a caudal fin with dorsal and ventral lobes. We describe new evidence for a notochord, cartilaginous arcualia, gill pouches, articulations within the proboscis, and multiple tooth rows adjacent to the mouth. This combination of characters, supported by phylogenetic analysis, identifies Tullimonstrum as a vertebrate, and places it on the stem lineage to lampreys (Petromyzontida). In addition to increasing the known morphological disparity of extinct lampreys, a chordate affinity for T. gregarium resolves the nature of a soft-bodied fossil which has been debated for more than 50 years.

To explore the repair effects of acupuncture for promoting the governor vessel and tranquilizing the mind (acupuncture technique) on cerebral white matter injury of premature infants. A total of 56 cases of cerebral whiter matter injury of premature infants, the fetal age less than 35 weeks were selected and randomized into an observation group (27 cases) and a control group (29 cases). The routine basic rehabilitation therapy was used in the two groups. Additionally, in the observation group, the acupuncture technique was added, once a day and the treatment for 15 days was as 1 course. Totally, 3 courses of treatment were required. Before and after treatment, the cranial magnetic resonance imaging (MRI) and the diffusion tensor imaging (DTI) were adopted to observe the location and severity of cerebral white matter injury. The Gesell developmental scale was used to assess the nerve motor development. After treatment, the difference was not significant statistically in the severity of cerebral white matter injury in the infants between the two groups ( P >0.05). The FA value of cerebral white matter in the interesting zone was increased as compared with that before treatment in the infants of the two groups (both P control groups ( P control group (all P 0.05). Acupuncture technique for promoting the governor vessel and tranquilizing the mind promotes the repair of the function in the premature infants with cerebral white matter injury and further benefits the promotion of the intelligence.

Dance of Two Monster Black Holes

This past December, researchers all over the world watched an outburst from the enormous black hole in OJ 287 an outburst that had been predicted years ago using the general theory of relativity.Outbursts from Black-Hole OrbitsOJ 287 is one of the largest supermassive black holes known, weighing in at 18 billion solar masses. Located about 3.5 billion light-years away, this monster quasar is bright enough that it was first observed as early as the 1890s. What makes OJ 287 especially interesting, however, is that its light curve exhibits prominent outbursts roughly every 12 years.Diagram illustrating the orbit of the secondary black hole (shown in blue) in OJ 287 from 2000 to 2023. We see outbursts (the yellow bubbles) every time the secondary black hole crosses the accretion disk (shown in red, ina side view) surrounding the primary (the black circle). [Valtonen et al. 2016]What causes the outbursts? Astronomers think that there is a second supermassive black hole, ~100 times smaller, inspiraling as it orbits the central monster and set to merge within the next 10,000 years. In this model, the primary black hole of OJ 287 is surrounded by a hot accretion disk. As the secondary black hole orbits the primary, it regularly punches through this accretion disk, heating the material and causing the release of expanding bubbles of hot gas pulled from the disk. This gas then radiates thermally, causing the outbursts we see.Attempts to model this scenario using Newtonian orbits all fail; the timing of the secondary black holes crossings through the accretion disk (as measured by when we see the outbursts) can only be explained by a model incorporating general-relativistic effects on the orbit. Careful observations and precise timing of these outbursts therefore provide an excellent test of general relativity.Watching a Predicted CrossingThe model of OJ 287 predicted another disk crossing in December 2015, so professional and amateur astronomers around the world readied more

You can count on monsters the first 100 numbers and their characters

Schwartz, Richard Evan

2010-01-01

Using a unique teaching tool designed to motivate kids to learn, this volume visually explores the concepts of factoring and the role of prime and composite numbers. The playful and colorful monsters are designed to give children (and even older audiences) an intuitive understanding of the building blocks of numbers and the basics of multiplication. The introduction and appendices can also help adult readers answer questions about factoring from their young audience. The artwork is crisp and creative and the colors are bright and engaging, making this volume a welcome deviation from standard math texts. CRC Press Author and NPR's Math Guy Keith Devlin spoke with Scott Simon about how the book makes finding prime numbers fun. "This is one of the most amazing math books for kids I have ever seen...," Devlin says. "Great colors, it's wonderful, and yet because [Schwartz] knows the mathematics, he very skillfully and subtly embeds mathematical ideas into the drawings."

Frankenstein’s Monster Comes Home: The ‘Two Cultures’ in Remix

James Barrett

2013-05-01

Full Text Available Frankenstein or the Modern Prometheus by Mary Shelley (1818 is the starting point for this reading of remix in relation to authorship and its implications for creative work. The monster in Frankenstein has no single author, or father, and is damned by his mixed parentage as much as by his inability to recreate himself. Alone, he falls into the waste as a product of the divide between poetry and science. The ‘two cultures’ coined by C. P. Snow (1956 address this same divide and lament its dominance in mid twentieth-century intellectual life. But contemporary remix culture that relies on digital media closes this gap as poets now write code and artists are technicians. In my close reading of five remixes I show that origin is no longer relevant in the mixed material realization of processes that are performed or ‘re-authored’ in reception. In these remixes the creator reinterprets by changing the context of remixed elements in the works. The result is textual hybrids that are remixed further in reception.

Morelos State is one of the most important regions of Mexico where several plant species are used in traditional medicine to influence central nervous system (CNS) activity; for example Tagetes lucida Cav. To investigate the ethnobotany, phytochemistry and pharmacology of the tranquilizing properties of T. lucida aerial parts. Data on the medicinal uses of T. lucida were explored by interviewing healers and merchants of local markets in different regions of Morelos State by using a questionnaire. Anxiolytic and/or sedative-like responses of the T. lucida were investigated in experimental models in mice such as: open-field, exploration cylinder, hole-board, plus-maze, and the barbituric-induced hypnosis potentiation. The possible mechanism of action was explored in the presence of WAY100635 (0.32mg/kg, i.p.) and flumazenil (10mg/kg, i.p.) antagonists. A feasible active compound was isolated and identified by using conventional chromatography, including UHPLC and MS (DART) [M+H]+ techniques. Interviews of healers and merchants from ten local regions of Morelos State showed that they recommended T. lucida as infusion and as tincture for several culture-bound syndromes associated with the CNS. Anxiolytic and sedative-like activities of polar extracts were corroborated in the experimental models; these effects were inhibited in the presence of 5-HT1A and GABA/BDZ receptor antagonists. Dimethylfraxetin was identified as one possible active compound. The results support the anxiolytic and sedative-like properties of T. lucida in traditional medicine by involving serotonergic and GABAergic neurotransmission and coumarinic constituents.

ICRF power-deposition profiles, heating and confinement of monster sawtooth and peaked-density profile discharges in JET

The ion cyclotron resonance heating of monster sawtooth (period greater than the energy confinement time) and pellet-fueled peaked-density profiles in limiter discharges of JET Tokamak are studied. The monster sawtooth is a characteristic JET regime which is related to fast ions generated during the minority ion heating. In the ICRF heating of peaked-density profile discharges, we find typically the T i0 is higher roughly by a factor of 2 and T e0 roughly by 35% at a fixed P TOT /n e0 when compared to non-peaked profile cases. Here, T e0 and T i0 are central electron and ion temperatures, respectively, n e0 is the central electron density and P TOT is the total input power. The ion heating is improved in the pellet case, in part, due to a higher collisionality between the background ions and the energetic minority, but more significantly by a reduction of local ion energy transport in the central region. The transport-code simulation of these discharges reveals that there is a reduction of both χ e and χ i in the central region of the plasma in the ICRF heated peaked-profile discharges where χ e and χ i are the electron and ion heat conductivities, respectively. The improvement of confinement is not explained quantitatively by any of the existing η i -driven turbulence theories as the n i parameter (η i = d ln T i /d ln n i where T i is the ion temperature and n i is the ion density), instead of dropping below the critical value, remains above it for most of the duration of the improved confinement phase. The physical mechanism(s) that plays a role in this improvement is not yet clear. (author)

Psychophysiological differentiation of two types of anxiety and its pharmacological modification by minor tranquillizer and beta-receptor-blocker.

To evaluate the influence of beta-blockers and/or minor tranquillizers on autonomic reactions during brief stress, 48 healthy subjects were randomised into 4 groups: A = 4 mg Pindolol, B = 1.5 mg Cloxazolam, C = Placebo, D = 4 mg Pindolol + 1.5 mg Cloxazolam. Subjects underwent four stress situations: Counting, noise, mental arithmetic and ergometry, each lasting 4 min with rest periods of 8 min in between. Electromyogram, finger pulse amplitude, heart rate, pulse wave velocity and electrodermal activity were recorded simultaneously on-line. Analysis of variance showed that the two drugs had significant main effects in different systems: Pindolol reduced heart rate, mainly during mental arithmetic and ergometry, Cloxazolam reduced electrodermal activity, mainly during noise. It can be concluded that different structured situations with a varying amount and type of anxiety induce different autonomic reactions; these reactions can be differentially modified by the drugs applied.

Microarray analysis of a salamander hopeful monster reveals transcriptional signatures of paedomorphic brain development

Science.gov (United States)

2010-01-01

Background The Mexican axolotl (Ambystoma mexicanum) is considered a hopeful monster because it exhibits an adaptive and derived mode of development - paedomorphosis - that has evolved rapidly and independently among tiger salamanders. Unlike related tiger salamanders that undergo metamorphosis, axolotls retain larval morphological traits into adulthood and thus present an adult body plan that differs dramatically from the ancestral (metamorphic) form. The basis of paedomorphic development was investigated by comparing temporal patterns of gene transcription between axolotl and tiger salamander larvae (Ambystoma tigrinum tigrinum) that typically undergo a metamorphosis. Results Transcript abundances from whole brain and pituitary were estimated via microarray analysis on four different days post hatching (42, 56, 70, 84 dph) and regression modeling was used to independently identify genes that were differentially expressed as a function of time in both species. Collectively, more differentially expressed genes (DEGs) were identified as unique to the axolotl (n = 76) and tiger salamander (n = 292) than were identified as shared (n = 108). All but two of the shared DEGs exhibited the same temporal pattern of expression and the unique genes tended to show greater changes later in the larval period when tiger salamander larvae were undergoing anatomical metamorphosis. A second, complementary analysis that directly compared the expression of 1320 genes between the species identified 409 genes that differed as a function of species or the interaction between time and species. Of these 409 DEGs, 84% exhibited higher abundances in tiger salamander larvae at all sampling times. Conclusions Many of the unique tiger salamander transcriptional responses are probably associated with metamorphic biological processes. However, the axolotl also showed unique patterns of transcription early in development. In particular, the axolotl showed a genome-wide reduction in mRNA abundance

In this paper, we compare experimental results of electron and ion-heating in discharges that feature monster sawtooth with those in pellet-produced peaked-density profile discharges which were heated with ICRF. Also we carry out a comprehensive analysis of ICRF-heated peaked-density profile discharges by a transport code to simulate the evolution of JET discharges and to provide an insight into the improved heating and confinement found in these discharges. In this analysis, the ICRF power-deposition profile in the minority-heating scenario is computed by the ray-tracing code BRAYCO that self-consistently takes the finite antenna geometry, its radiation spectrum and the hot-plasma damping into account. The power delivered to ions and electrons is calculated based on Stix model. (author) 10 refs., 5 figs

The present paper focuses primarily on a philological and historical study of the Arśapraśamanisūtra ("The Sütra of the tranquilization of hemorrhoids"). This Sūtra is one of the Buddhist scriptures that are characterized by the magico-religious treatment of various diseases, especially by means of "healing spells" (skt. dhāranī or mantra), as shown by the preliminary survey in our previous paper "The Tradition of healing with magical spells as seen in Buddhist texts", Journal of the Japan Society of Medical History 55/1 (2009), 77-96. The original text of the Arśapraśamanisūtra, most probably written in Sanskrit, is lost whereas its Chinese and Tibetan translations have survived. After an introductory summary, we provide critically edited texts of the Tibetan and Chinese translations accompanied by their Japanese translations with critical notes and annotations. In particular, the Tibetan translation presented here has been critically edited for the first time on the basis of collation of the five editions of the Tibetan Buddhist Canon. In our next paper we will analyze the descriptions of hemorrhoids as found in the Sūtra in comparison with those illustrated in classical Ayurveda literature. And we will also offer further observations about the methods and principles for the treatment and healing of hemorrhoid that are attested in Buddhist scriptures.

Monstruos y poder en El obsceno pájaro de la noche de José Donoso

Carmen Martin

2013-04-01

Full Text Available The essay “Monstruos y poder en El obsceno pájaro de la noche” studies the figure of the monster in the novel El obsceno pájaro de la noche by Chilean author José Donoso. Based on Michel Foucault’s definition of the monster developed in his work Los anormales, this analysis focuses on the way in which the figure of the monster, understood as a marginal entity, threatens social systems and structures by proposing a new discourse in which such conventions are denied, subverted and replaced. Therefore, the monster appears in essence as a transgressive figure, which can be understood as an attack on the establishment and furthermore as an allegory to those institutions and social values that frame modern societies and more specifically those established in Chile in the 1970s.

Cyborgs and monsters on non-places: aspects of education at a supermodern society

Full Text Available The post-modern society, especially in westernized cultures, has the peculiarity of the presence of some components: capitalism, power systems, technologies for their exercise, schizophrenic behavior, fortification of segregation and repression actions. This is the political, social and cultural background of the School: an institution that seeks the adjustment of individuals to civic life and labor. Based on some ideas of Michel Foucault and the duo consisting of Gilles Deleuze and Felix Guattari the analysis of the instruments of power and the actions contained therein is made. Besides these, we present the definitions of concepts supported Marc Auge, on the characteristics of non-place in supermodernity, a place devoid of experience; Donna Haraway, with its ciborgologia, offering the chance to replace the dichotomy of man versus machine by an ontology human-machine and Jeffrey Jerome Cohen, who in seven theses on the monsters, look back to the monstrosity that surrounds us. It is so identified the element that the School intend to reach: an infant and monstrous cyborg who is required to remain in a non-place.

This article offers a new reading of the well-known diary kept by the Florentine apothecary Luca Landucci between 1450 and 1516, examining its accounts of prodigies and other "monstrous" occurrences from a modern scientific point of view. Particular consideration is given to descriptions of a variety of birth defects observed in various Italian cities at the time, providing explanations for each case based on the latest medical theories. A detailed analysis is provided for a case of cranioschisis recorded in Volterra in 1474, a case of Opitz syndrome occurring in Venice in 1489, the birth of conjoined twins in Padua in the same year, conjoined triplets born to a 60-year-old woman in Venice, the well-publicized account of the 1512 Ravenna monster and, finally, the thoraco-acephalus tetramelus adolescent that Landucci personally observed in Florence in 1513.

Feeding the Monster

Near-infrared images of the active galaxy NGC 1097, obtained with the NACO adaptive optics instrument on ESO's Very Large Telescope, disclose with unprecedented detail a complex central network of filamentary structure spiralling down to the centre of the galaxy. These observations provide astronomers with new insights on how super-massive black holes lurking inside galaxies get fed. "This is possibly the first time that a detailed view of the channelling process of matter, from the main part of the galaxy down to the very end in the nucleus is released," says Almudena Prieto (Max-Planck Institute, Heidelberg, Germany), lead author of the paper describing these results. Located at a distance of about 45 million light-years in the southern constellation Fornax (the Furnace), NGC 1097 is a relatively bright, barred spiral galaxy seen face-on. At magnitude 9.5, and thus just 25 times fainter than the faintest object that can be seen with the unaided eye, it appears in small telescopes as a bright, circular disc. NGC 1097 is a very moderate example of an Active Galactic Nucleus (AGN), whose emission is thought to arise from matter (gas and stars) falling into oblivion in a central black hole. However, NGC 1097 possesses a comparatively faint nucleus only, and the black hole in its centre must be on a very strict "diet": only a small amount of gas and stars is apparently being swallowed by the black hole at any given moment. Astronomers have been trying to understand for a long time how the matter is "gulped" down towards the black hole. Watching directly the feeding process requires very high spatial resolution at the centre of galaxies. This can be achieved by means of interferometry as was done with the VLTI MIDI instrument on the central parts of another AGN, NGC 1068 (see ESO PR 17/03), or with adaptive optics [1]. Thus, astronomers [2] obtained images of NGC 1097 with the adaptive optics NACO instrument attached to Yepun, the fourth Unit Telescope of ESO's VLT

The ultrastructural changes in the liver cells induced by high doses of Benzodiazepine Tranquilizing drugs: An experimental transmission electron microscopic study on male guinea pigs

International Nuclear Information System (INIS)

Bisher, Ameen S. Ahmad

2008-01-01

Benzodiazepines are tranquilizing psychotropic drugs. Unfortunately, despite their therapeutic benefits, they are illegally consumed in high doses by some addicts to reach a sedative, exhilarative and euphoria state similar to that produced by narcotic substances. The present study, using transmission electron microscope on male guinea pigs, aims to investigate the potential ultrastructural changes in the liver cells induced by the high doses of Benzodiazepines. Animals in three treated groups administrated a daily combined dose consisted of (10mg Alprazolam with 10mg Diazepam/day/animal) for three different treatment periods: 7, 15, and 25 days. The ultrastructural examination of the hepatocytes of the animals treated for 15 days showed limited changes in the form of marginal heterochromatine accompanied with marginal nucleoli enlargement. On the other hand, severe ultrastructural damages are observed in the animals treated for 25 days, which appeared in the following various patterns: fatty degeneration of the hepatocytes as indicated by the accumulation of large number of lipid droplets in the cytoplasm, marked nuclear atrophy in some necrotic hepatocytes, massive nuclear degeneration in other hepatocytes, mitochondrial damages in the form of cristea destruction accompanied with abnormal oval shape, massive lysis of the cytoplasmic organelles with severe plasma membrane rupture. In conclusion, the observed ultrastructural damages in the present study may refer to the potential hepatotoxic effects of the high dose of Benzodiazepins. It is recommended that much more official restrictions should be applied on the pharmacies sector to prevent any illegal selling of these drugs in order to prevent abusers from obtaining them, as unfortunately in some developing countries the illegal selling of these drugs is known to occur due to the absence of official control.

We report an integral-field spectroscopic (IFS) observation of a gravitationally lensed spiral galaxy A1689B11 at redshift z = 2.54. It is the most ancient spiral galaxy discovered to date and the second kinematically confirmed spiral at z≳ 2. Thanks to gravitational lensing, this is also by far the deepest IFS observation with the highest spatial resolution (˜400 pc) on a spiral galaxy at a cosmic time when the Hubble sequence is about to emerge. After correcting for a lensing magnification of 7.2 ± 0.8, this primitive spiral disk has an intrinsic star formation rate of 22 ± 2 M ⊙ yr-1, a stellar mass of {10}9.8+/- 0.3 M ⊙, and a half-light radius of {r}1/2=2.6+/- 0.7 {kpc}, typical of a main-sequence star-forming galaxy at z˜ 2. However, the Hα kinematics show a surprisingly tranquil velocity field with an ordered rotation ({V}{{c}}=200+/- 12 km s-1) and uniformly small velocity dispersions ({V}σ ,{mean}=23 +/- 4 km s-1 and {V}σ ,{outer - {disk}}=15+/- 2 km s-1). The low gas velocity dispersion is similar to local spiral galaxies and is consistent with the classic density wave theory where spiral arms form in dynamically cold and thin disks. We speculate that A1689B11 belongs to a population of rare spiral galaxies at z≳ 2 that mark the formation epoch of thin disks. Future observations with the James Webb Space Telescope will greatly increase the sample of these rare galaxies and unveil the earliest onset of spiral arms.

This wake is also can be visible on the surface of the lake, 5) the final stage of interaction is the formation of solitons and the second internal mode. The appearance of surface wake in such idealized elongated elliptic-shape lake was the motivation for carrying further modeling of internal seiches in the real lake. This phenomenon can be the explanation of the fact that number of eyewitness around the world claimed to see "lake monsters" moved rapidly and then submerged leaving a wake. Its usually occur in elongated lakes in moderate latitude with a well defined seasonal termocline. Numerical modeling of the interaction of internal seiche with a North end of the Loch Ness confirms possibility of the supercritical internal jet generation and subsequent internal and surface disturbances. We hypotheses that some of eyewitness and legends on the "lake monsters" can be explained by such observations of suddently occurred surface wake behind disturbance generated by focusing flows by bottom topography.

Cloverfield's monster is effective precisely because we never really see it, because it remains in our peripheral vision and seems to be mutating, changing, multiple and yet perhaps still one, all at the same time. To say that the monster is abject, is to miss the point. Being abject is part of a monster's very nature, but the monster in Cloverfield is both frightingly different and hauntingly familiar. We have seen such monsters many times before in earlier movies, so we cannot fully feel th...

Subduing the green-eyed monster: bridging the psychopharmacological and psychosocial treatment perspective in understanding pathological jealousy.

Human being is not spared from a broad-ranged emotional state, including being jealous. Jealousy has both affective-cognitive and behavioural-evaluative dimension where the person perceives, or experiences a real threat on a valued relationship. As this complex emotion becomes irrational and not amenable to reason, it later transforms into a dangerously 'green-eyed monster'. This perilous situation which is viewed as pathological jealousy is a form of delusion, which is maintained by a fixed and false reasoning in an originally entrusted intimate relationship. Pathological jealousy is equally prevailing among both gender, and with a greater ubiquitous among the geriatric population. The role of dopamine hyperactivity in the fronto-parietal-temporal region was implicated, with the anatomical mapping of the ventromedial prefrontal cortex (vmPFC), cingulate gyrus (CG), and amygdala involvement in the context of the disease's neurobiology. The etiology of pathological jealousy includes major psychiatric disorders, i.e. delusional disorder, schizophrenia, mood disorder, organic brain syndrome, and among others, the drug-induced psychosis. The role of relationship issues and psychodynamic perspective, i.e. psychological conflicts with dependence on a romantic partner, and low self-esteem are involved. Pathological jealousy inherits high-risk forensic psychiatry entanglement, which may warrant intensive intervention, including hospital admission and antipsychotic treatment. Treatment options include an early recognition, managing underlying neuropsychiatric disorders, psycho education, cognitive psychotherapy, and choosing an effective psychopharmacological agent. The management strategy may also resort to a geographical intervention, i.e. separation between both persons to complement the biological treatment.

The moderated relationship of appearance valence on appearance self consciousness: development and testing of new measures of appearance schema components.

Directory of Open Access Journals (Sweden)

Timothy P Moss

Full Text Available This paper describes the creation and psychometric properties of two independent measures of aspects of appearance schematicity--appearance salience and valence, assessed by the CARSAL and CARVAL, and their relation to appearance self-consciousness. Five hundred and ninety two participants provided data in a web based task. The results demonstrate the sound psychometric properties of both scales. This was demonstrated by good item total characteristics, good internal reliability of each scale, and the independence of the two scales shown through principal components analysis. Furthermore, the scales show independent and moderated relationships with valid measures of appearance related psychosocial distress. Negatively valenced appearance information was associated with increased appearance self-consciousness. More crucially, the impact of negative valence on appearance self-consciousness was exacerbated by the moderating effect increased salience of appearance.

Evaluation of use of tiletamine/zolazepam for anesthesia of bullfrogs and leopard frogs.

Science.gov (United States)

Letcher, J; Durante, R

1995-07-01

Use of tiletamine hydrochloride and zolazepam hydrochloride (1:1 fixed ratio combination) as an anesthetic agent in 2 anuran species was studied. A dosage of 5 mg/kg of body weight, administered IM, resulted in variable weak tranquilization. Intramuscular administration at dosages of 10 and 20 mg/kg induced variable states of tranquilization or anesthesia in leopard frogs (Rana pipiens) and bullfrogs (R catesbeiana). The dosages of 50 mg/kg induced anesthesia with greater consistency than lower dosages in bullfrogs, but resulted in mortalities. The same dosage was uniformly fatal in leopard frogs. Neither gross nor histologic lesions were identified in the frogs that died. Depth and duration of anesthesia was dosage related. At the 20 and 50 mg/kg dosages, leopard frogs attained a greater depth of anesthesia and remained anesthetized for a significantly greater duration than did bullfrogs; however, at the 5 and 10 mg/kg dosages, bullfrogs developed greater tranquilization for longer periods than did leopard frogs. Results of this study revealed profound intraspecies variation in depth and duration of effect of tiletamine/zolazepam; therefore, the drug does not appear to be a suitable injectable anesthetic in anurans.

`This paper considers the monstrous nature of medical tools and devices through the lens of horror cinema and the art of Damien Hirst. In it I argue for a shift from the monster and the monstrous as organic to the threat of the monster as an inorganic object in tools such as the scalpel and syringe. However, the metaphorical significance of the monster is sustained in these tools where human technological creations continue the discourse of the monster as a product of human creativity.

Effect of opponent type on moral emotions and responses to video game play.

Science.gov (United States)

Lin, Shu-Fang

2011-11-01

This study suggests that fighting against different types of opponents in video games (e.g., human opponents vs. monster opponents) may lead to different emotional responses and moral judgments toward game characters. Based on Bandura's moral disengagement theory, this study proposes that shooting at monster opponents makes game players feel less guilty and judge the player-controlled character as more morally justified. An experiment was conducted in which participants played shooting games with either human opponents or monster opponents. The results show that when playing against monster opponents, participants felt both less ashamed and less guilty, reported enjoying the game more, and judged their character as more justified than participants who played against human opponents.

A fast and simple liquid chromatography with tandem mass spectrometry method for detection and confirmation of tranquilizers (chlorpromazine, propionylpromazine, acepromazine, triflupromazine, promazine, azaperone and its metabolite, azaperol) and beta-blocker (carazolol) in porcine and bovine kidney has been presented. The method relies on the extraction with acetonitrile followed by centrifugation. After evaporation of acetonitrile, the residue was reconstituted in a mobile phase and filtrated. The separation of analytes was performed on a C18 column using a mobile phase of acetonitrile and ammonium formate buffer (0.05 M, pH 4.5) with gradient elution. The electrospray ionization was used to obtain the protonated molecules [M+H]{sup +} and two product ions were monitored for each compound. For quantification deutered internal standards were used. The whole method has been validated according to the European Union requirements. Specificity, decision limit (CC{alpha}), detection capability (CC{beta}), trueness and precision were determined. The results showed good trueness ranged from 73.2% to 110.6% with a good R.S.D., less than 13.0% under within-laboratory reproducibility conditions. The calculated critical concentrations of CC{alpha} for phenothiazines were between 5.8 and 6.6 {mu}g kg{sup -1} while for azaperone CC{alpha} was 105.5 {mu}g kg{sup -1} and for azaperol was 121.4 {mu}g kg{sup -1}. CC{alpha} for carazolol was 16.7 {mu}g kg{sup -1} in bovine and 21.9 {mu}g kg{sup -1} in porcine kidney. CC{beta} for phenothiazines were between 6.3 and 7.6 {mu}g kg{sup -1}, for azaperone was 119.0 {mu}g kg{sup -1} and for azaperol was 140.0 {mu}g kg{sup -1}. For carazolol in bovine kidney CC{beta} was 18.6 {mu}g kg{sup -1} whereas in porcine kidney was 24.4 {mu}g kg{sup -1}.

Evolution, Appearance, and Occupational Success

Directory of Open Access Journals (Sweden)

Anthony C. Little

2012-12-01

Full Text Available Visual characteristics, including facial appearance, are thought to play an important role in a variety of judgments and decisions that have real occupational outcomes in many settings. Indeed, there is growing evidence suggesting that appearance influences hiring decisions and even election results. For example, attractive individuals are more likely to be hired, taller men earn more, and the facial appearance of candidates has been linked to real election outcomes. In this article, we review evidence linking physical appearance to occupational success and evaluate the hypothesis that appearance based biases are consistent with predictions based on evolutionary theories of coalition formation and leadership choice. We discuss why appearance based effects are so pervasive, addressing ideas about a “kernel of truth” in attributions and about coalitional psychology. We additionally highlight that appearance may be differently related to success at work according to the types of job or task involved. For example, leaders may be chosen because the characteristics they possess are seen as best suited to lead in particular situations. During a time of war, a dominant-appearing leader may inspire confidence and intimidate enemies while during peace-time, when negotiation and diplomacy are needed, interpersonal skills may outweigh the value of a dominant leader. In line with these ideas, masculine-faced leaders are favored in war-time scenarios while feminine-faced leaders are favored in peace-time scenarios. We suggest that such environment or task specific competencies may be prevalent during selection processes, whereby individuals whose appearance best matches perceived task competences are most likely selected, and propose the general term “task-congruent selection” to describe these effects. Overall, our review highlights how potentially adaptive biases could influence choices in the work place. With respect to certain biases

National Needs for Appearance Metrology

Science.gov (United States)

Nadal, Maria E.

2003-04-01

Appearance greatly influences a customer's judgement of the quality and acceptability of manufactured products, as yearly there is approximately $700 billion worth of shipped goods for which overall appearance is critical to their sale. For example, appearance is reported to be a major factor in about half of automobile purchases. The appearance of an object is the result of a complex interaction of the light field incident upon the object, the scattering and absorption properties of the object, and human perception. The measurable attributes of appearance are divided into color (hue, saturation, and lightness) and geometry (gloss, haze). The nature of the global economy has increased international competition and the need to improve the quality of many manufactured products. Since the manufacturing and marketing of these products is international in scope, the lack of national appearance standard artifacts and measurement protocols results in a direct loss to the supplier. One of the primary missions of the National Institute of Standards and Technology (NIST) is to strengthen the U.S. economy by working with industry to develop and apply technology, measurements and standards. The NIST Physics Laboratory has established an appearance metrology laboratory. This new laboratory provides calibration services for 0^o/45^o color standards and 20^o°, 60^o°, and 85^o° specular gloss, and research in the colorimetric characterization of gonioapparent including a new Standard Reference Material for metallic coatings (SRM 2017) and measurement protocols for pearlescent coatings. These services are NIST's first appearance metrology efforts in many years; a response to needs articulated by industry. These services are designed to meet demands for improved measurements and standards to enhance the acceptability of final products since appearance often plays a major role in their acceptability.

Computed tomographic scans of 34 patients with ovarian metastases were reviewed to assess the radiographic appearances and to correlate these with the primary neoplasms. Primary neoplasms were located in the colon (20 patients), breast (six), stomach (five), small bowel (one), bladder (one), and Wilms tumor of the kidney (one). The radiographic appearance of the metastatic lesions could be described as predominantly cystic (14 lesions), mixed (12 lesions), or solid (seven lesions). The cystic and mixed lesions tended to be larger in overall diameter than the solid. The metastases from gastric carcinoma appeared solid in four of five cases. The metastases from the other neoplasms had variable appearances simulating primary ovarian carcinoma

The role of appearance schematicity in the internalization of media appearance ideals: A panel study of preadolescents.

Science.gov (United States)

Rousseau, Ann; Gamble, Hilary; Eggermont, Steven

2017-10-01

Individuals who are more strongly invested in their appearance, appearance schematics, have a tendency to engage in appearance-related comparison. Appearance schematicity consists of two components. The self-evaluative component concerns the degree to which appearance is central to self-worth, referred to as dysfunctional appearance beliefs. Motivational salience refers to the engagement in behaviors designed to enhance appearance, such as body surveillance. Based on a three-wave panel survey of 973 Flemish preadolescents (M age  = 11.15, SD = 1.13) we found that the motivational and self-evaluative components had a different impact on media internalization. For preadolescents who engaged in more body surveillance, watching television resulted in more media internalization. For preadolescents who had fewer dysfunctional appearance beliefs, watching television resulted in more media internalization. These findings suggest that appearance schematicity is an important susceptibility variable in the relationship between TV-exposure and media internalization, and emphasize the importance of investigating individual dispositions beyond gender differences.

Assessing the Impact of an Interactive Mobile Game on Tobacco-Related Attitudes and Beliefs: The Truth Campaign's "Flavor Monsters".

2015-12-01

Given that over 97 percent of American teens play videogames, it is not surprising that many "games for health" target youth. Although tobacco use is the leading cause of preventable death in the United States, few digital games focus on preventing this behavior. The aims of this study were twofold: (1) to determine if youth will play a game with tobacco-related information and themes and (2) to explain the relationship between the truth(®) (Legacy, Washington, DC) campaign's "Flavor Monsters" gameplay and shifts in game-related tobacco knowledge, attitudes, and beliefs. First, two versions of the game, with different amounts of tobacco-related content, were developed to examine the influence of tobacco-related content on player engagement, length of play, awareness of the truth brand, and receptivity to the game. No statistically significant differences were found for engagement (P=0.81), length of play (P=0.10), or awareness of the truth brand (P=0.67). Using an online survey through a preexisting online panel of 13-24 year olds, a longitudinal (n=693) design was used whereby exposure to messages varied naturally over time. Because of the large number of anti-tobacco industry attitude questions, we created an Anti-Tobacco Industry (ATI) Index based on the results of a factor analysis. Although gameplay was not a predictor of lower levels of intention to smoke, level mastered was a significant positive predictor of ATI Index attitudes score at 3 months, controlling for baseline ATI Index score, age, gender, and ever cigarette use (P=0.002). Longitudinal findings indicate a cumulative and enduring effect, suggesting that anti-tobacco content can be successfully integrated within a mobile game to help increase anti-tobacco attitudes.

Breaking the circle: challenging Western sociocultural norms for appearance influences young women's attention to appearance-related media.

Mischner, Isabelle H S; van Schie, Hein T; Engels, Rutger C M E

2013-06-01

Paying attention to thin media models may negatively affect women's self-evaluation. This study aimed to reduce the amount of attention that young women give to appearance-related information by challenging the sociocultural norms for appearance, and studied the moderating role of self-esteem. Seventy-one college women either received norm-confirming, norm-challenging, or no information regarding the sociocultural norms for appearance. Subsequently, participants' visual attention to appearance-related and neutral advertisements was measured using an eye-tracker. The results demonstrate that when no information or norm-confirming information was received, women with lower self-esteem paid more attention to the appearance-related advertisements than women with higher self-esteem. Importantly however, when norm-challenging information was received, women with lower self-esteem paid significantly less attention to the appearance-related ads than women with lower self-esteem who did not receive this manipulation. These findings indicate that challenging the sociocultural norms for appearance can attenuate the amount of attention women give to appearance-related media. Copyright © 2013 Elsevier Ltd.

The essay “Monstruos y poder en El obsceno pájaro de la noche” studies the figure of the monster in the novel El obsceno pájaro de la noche by Chilean author José Donoso. Based on Michel Foucault’s definition of the monster developed in his work Los anormales, this analysis focuses on the way in which the figure of the monster, understood as a marginal entity, threatens social systems and structures by proposing a new discourse in which such conventions are denied, subverted and replaced.

Appearance questions can be misleading

DEFF Research Database (Denmark)

Hansen, Mikkel; Markman, Ellen M.

2005-01-01

Preschoolers' success on the appearance-reality task is a milestone in theory-of-mind development. On the standard task children see a deceptive object, such as a sponge that looks like a rock, and are asked, "What is this really?" and "What does this look like?" Children below 4 1/2 years of age...... fail saying that the object not only is a sponge but also looks like a sponge. We propose that young children's difficulty stems from ambiguity in the meaning of "looks like." This locution can refer to outward appearance ("Peter looks like Paul") but in fact often refers to likely reality ("That looks...... like Jim"). We propose that "looks like" is taken to refer to likely reality unless the reality is already part of the common ground of the conversation. Because this joint knowledge is unclear to young children on the appearance-reality task, they mistakenly think the appearance question is about...

Mammographic appearances of male breast disease.

Science.gov (United States)

Appelbaum, A H; Evans, G F; Levy, K R; Amirkhan, R H; Schumpert, T D

1999-01-01

Various male breast diseases have characteristic mammographic appearances that can be correlated with their pathologic diagnoses. Male breast cancer is usually subareolar and eccentric to the nipple. Margins of the lesions are more frequently well defined, and calcifications are rarer and coarser than those occurring in female breast cancer. Gynecomastia usually appears as a fan-shaped density emanating from the nipple, gradually blending into surrounding fat. It may have prominent extensions into surrounding fat and, in some cases, an appearance similar to that of a heterogeneously dense female breast. Although there are characteristic mammographic features that allow breast cancer in men to be recognized, there is substantial overlap between these features and the mammographic appearance of benign nodular lesions. The mammographic appearance of gynecomastia is not similar to that of male breast cancer, but in rare cases, it can mask malignancy. Gynecomastia can be mimicked by chronic inflammation. All mammographically lucent lesions of the male breast appear to be benign, similar to such lesions in the female breast.

“Þur sarriþu þursa trutin”: monster-fighting and medicine in early medieval Scandinavia

Directory of Open Access Journals (Sweden)

Hall, Alaric

2009-06-01

Full Text Available This paper seeks evidence among our extensive Scandinavian mythological texts for an area which they seldom discuss explicitly: the conceptualisation and handling of illness and healing. Its core evidence is two runic texts (the Canterbury Rune-Charm and the Sigtuna Amulet which conceptualise illness as a þurs (‘ogre, monster’. The article discusses the semantics of þurs, arguing that illness and supernatural beings could be conceptualised as identical in medieval Scandinavia. This provides a basis for arguing that myths in which gods and heroes fight monsters provided a paradigm for the struggle with illness. The article proceeds, more speculatively, to use the Eddaic poem Skírnismál and the Finnish Riiden synty as the basis for arguing that one cause of illness could be the transgression of moral norms.

Este artículo tiene por objetivo encontrar pruebas en los numerosos textos mitológicos escandinavos sobre un tema sobre el que pocas veces estos tratan de forma explícita: la conceptualización y el tratamiento de las enfermedades y su curación. La principal prueba se encuentra en dos textos rúnicos (el Canterbury Rune-Charm (El conjuro rúnico de Canterbury y el Sigtuna Amulet (El amuleto de Sigtuna que conceptualizan la enfermedad como un þurs (‘ogro, monstruo’. El artículo trata sobre la semántica de þurs y sostiene que las enfermedades y los seres sobrenaturales podían conceptualizarse como idénticos en la Escandinavia de la época medieval, en base a lo cual afirma que los mitos en los que los dioses y los héroes luchan contra los monstruos representaban un paradigma de la lucha contra las enfermedades. De forma más especulativa, el artículo utiliza el poema eddaico Skírnismál y el poema finlandés Riiden synty como base para sostener que la transgresión de las normas morales podía considerarse una posible causa de las enfermedades.

Exploring the relationship between appearance-contingent self-worth and self-esteem: The roles of self-objectification and appearance anxiety.

Science.gov (United States)

Adams, Katherine E; Tyler, James M; Calogero, Rachel; Lee, Jenifer

2017-12-01

Previous work has shown that both an appearance-contingent self-worth (i.e., staking one's overall self-evaluation on one's physical appearance) and self-objectification are associated with higher appearance anxiety and lower self-esteem among women. Although prior evidence separately links both appearance-contingent self-worth and self-objectification to these negative outcomes, no work has examined the mediating processes that may underlie this relationship. With the current project, we examined the relationship between appearance-contingent self-worth and self-objectification, and the degree to which this relationship is associated with higher appearance anxiety and lower overall self-esteem. We hypothesized that appearance-contingent self-worth would be positively associated with self-objectification; in turn, we expected self-objectification to be related to higher appearance anxiety, and ultimately, lower self-esteem. Across two studies, one cross-sectional (N=208) and one short-term longitudinal (N=191), we found compelling support for this hypothesis. These findings have practical and theoretical significance for both the self-objectification and contingent self-worth literatures. Published by Elsevier Ltd.

Appearance-change instruction effects on eyewitness lineup identification accuracy are not moderated by amount of appearance change.

Science.gov (United States)

Molinaro, Peter F; Arndorfer, Andrea; Charman, Steve D

2013-12-01

Instructing witnesses that a criminal may have changed appearance prior to showing them a lineup has been shown to increase false identifications without increasing correct identifications (S. D. Charman & G. L. Wells, 2007, Is the appearance-change instruction a good idea? Law and Human Behavior, Vol. 31, pp. 3-22). However, the generalizability of the effects of this appearance-change instruction (ACI) is unknown, and there are reasons to believe that the instruction's effects may be moderated by the amount of appearance change the criminal has actually undergone. The current study tested this hypothesis. Undergraduate students (N = 315) were exposed to a series of target faces and lineups, some of which contained the target and some of which did not, and made identification decisions. Half of the participants received a standard ACI prior to each lineup; the other half did not. The targets varied with respect to the amount to which their appearance had changed. Results indicated that the ACI inflated false identifications without inflating correct identifications, and that these effects did not depend on the amount of appearance change the target had undergone. Current recommendations to administer the ACI seem to be unfounded and may be harmful to the reliability of identification evidence. (c) 2013 APA, all rights reserved

The CT appearance of intraoral chewing gum

When imaged, intraoral chewing gum has the potential to be misdiagnosed. Chewing gum has a characteristic appearance on CT: it is ovoid in shape, hyperdense, and has small internal locules of air. Reports have described the appearance of gum on radiographs and abdominal CT images; however, no reports could be found detailing its appearance within the mouth. This report describes the appearance of intraoral chewing gum as well as the properties of the gum that lead to this appearance. Because of the potential for misdiagnosis, screening for intraoral foreign bodies should be considered prior to imaging. (orig.)

The relationship between color and lightness appearance and the perception of depth has been studied since a while in the field of perceptual psychology and psycho-physiology. It has been found that depth perception affects the final object color and lightness appearance. In the stereoscopy research field, many studies have been proposed on human physiological effects, considering e.g. geometry, motion sickness, etc., but few has been done considering lightness and color information. Goal of this paper is to realize some preliminar experiments in Virtual Reality in order to determine the effects of depth perception on object color and lightness appearance. We have created a virtual test scene with a simple 3D simultaneous contrast configuration. We have created three different versions of this scene, each with different choices of relative positions and apparent size of the objects. We have collected the perceptual responses of several users after the observation of the test scene in the Virtual Theater of the University of Milan, a VR immersive installation characterized by a semi-cylindrical screen that covers 120° of horizontal field of view from an observation distance of 3.5 m. We present a description of the experiments setup and procedure, and we discuss the obtained results.

Semantic attributes for people's appearance description: an appearance modality for video surveillance applications

Science.gov (United States)

Frikha, Mayssa; Fendri, Emna; Hammami, Mohamed

2017-09-01

Using semantic attributes such as gender, clothes, and accessories to describe people's appearance is an appealing modeling method for video surveillance applications. We proposed a midlevel appearance signature based on extracting a list of nameable semantic attributes describing the body in uncontrolled acquisition conditions. Conventional approaches extract the same set of low-level features to learn the semantic classifiers uniformly. Their critical limitation is the inability to capture the dominant visual characteristics for each trait separately. The proposed approach consists of extracting low-level features in an attribute-adaptive way by automatically selecting the most relevant features for each attribute separately. Furthermore, relying on a small training-dataset would easily lead to poor performance due to the large intraclass and interclass variations. We annotated large scale people images collected from different person reidentification benchmarks covering a large attribute sample and reflecting the challenges of uncontrolled acquisition conditions. These annotations were gathered into an appearance semantic attribute dataset that contains 3590 images annotated with 14 attributes. Various experiments prove that carefully designed features for learning the visual characteristics for an attribute provide an improvement of the correct classification accuracy and a reduction of both spatial and temporal complexities against state-of-the-art approaches.

The purpose of this study was to examine the appearance of struma ovarii on MR and CT images. All 13 patients showed both cystic and solid components with a multilobulated surface and thickened septa. Various signal intensities were seen on both T1WI and T2WI. The cystic component, which showed low signal intensity on T2WI, showed high density on CT images. The characteristic MR and CT appearance of struma ovarii appears to be that of multicystic tumor indicating the presence of viscid materials containing iodine. (author)

The decision criteria for the physical appearance of pharmaceutical products are subjective and qualitative means of evaluation that are based entirely on human interpretation. In this study, we have developed a comprehensive method for the quantitative analysis of the physical appearance of film coated tablets. Three different kinds of film coated tablets with considerable differences in their physical appearances were manufactured as models, and their surface roughness, contact angle, color measurements and physicochemical properties were investigated as potential characteristics for the quantitative analysis of their physical appearance. All of these characteristics were useful for the quantitative evaluation of the physical appearances of the tablets, and could potentially be used to establish decision criteria to assess the quality of tablets. In particular, the analysis of the surface roughness and film coating properties of the tablets by terahertz spectroscopy allowed for an effective evaluation of the tablets' properties. These results indicated the possibility of inspecting the appearance of tablets during the film coating process.

Full Text Available We investigated the memory colour effect for colour diagnostic artificial objects. Since knowledge about these objects and their colours has been learned in everyday life, these stimuli allow the investigation of the influence of acquired object knowledge on colour appearance. These investigations are relevant for questions about how object and colour information in high-level vision interact as well as for research about the influence of learning and experience on perception in general. In order to identify suitable artificial objects, we developed a reaction time paradigm that measures (subjective colour diagnosticity. In the main experiment, participants adjusted sixteen such objects to their typical colour as well as to grey. If the achromatic object appears in its typical colour, then participants should adjust it to the opponent colour in order to subjectively perceive it as grey. We found that knowledge about the typical colour influences the colour appearance of artificial objects. This effect was particularly strong along the daylight axis.

This review illustrates the varied appearances of benign and malignant papillary breast tumours, as identified by a breast cancer-screening programme. The commonest mammographic appearance of a papillary tumour is as a soft-tissue mass, with calcification present in less than half of cases. When calcification is present the pattern is variable, but clusters of pleomorphic calcification can occur, sometimes resembling the mammographic appearance of invasive ductal carcinoma. Ultrasonography of papillary lesions typically shows a solid, oval, intraductal mass, often associated with duct dilatation. A cystic component is also commonly seen, and lesions may appear hypervascular on colour Doppler ultrasound. Magnetic resonance imaging (MRI) has a high sensitivity, but low specificity for detecting papillary tumours, and is useful in establishing the extent and distribution of lesions in patients with multiple papillomatosis. Despite a benign histology on core biopsy, an argument exists for complete surgical excision of all papillary tumours, as a significant proportion of papillomas will contain foci of atypia or overt malignant change

Increasingly, third-party insurers deny coverage to patients with posttraumatic and congenital facial deformities because these are not seen as "functional." Recent facial transplants have demonstrated that severely deformed patients are willing to undergo potentially life-threatening surgery in search of a normal physiognomy. Scant quantitative research exists that objectively documents appearance as a primary "function" of the face. This study was designed to establish a population-based definition of the functions of the human face, rank importance of the face among various anatomical areas, and determine the risk value the average person places on a normal appearance. Voluntary adult subjects (n = 210) in three states aged 18 to 75 years were recruited using a quota sampling technique. Subjects completed study questionnaires of demography and bias using the Gamble Chance of Death Questionnaire and the Rosenberg Self-Esteem Scale. The face ranked as the most important anatomical area for functional reconstruction. Appearance was the fifth most important function of the face, after breathing, sight, speech, and eating. Normal facial appearance was rated as very important for one to be a functioning member of American society (p = 0.01) by 49 percent. One in seven subjects (13 percent) would accept a 30 to 45 percent risk of death to obtain a "normal" face. Normal appearance is a primary function of the face, based on a large, culturally diverse population sample across the lifespan. Normal appearance ranks above smell and expression as a function. Restoration of facial appearance is ranked the most important anatomical area for repair. Normal facial appearance is very important for one to be a functional member of American society.

A crayon fragment was determined to be the source of a foreign body inflammatory process in the masticator space of a 15-month-old boy. The appearance of the crayon on CT and MR imaging was unexpected, leading to a further analysis of the imaging features of crayons. To investigate and characterize the imaging appearance of crayons at CT and MRI. The authors obtained CT and MR images of 22 crayons from three manufacturers and three non-pigmented crayons cast by the authors. CT attenuation of the crayons and diameter of the MRI susceptibility signal dropout were plotted versus brand and color. All crayons demonstrated a longitudinal central hypo-attenuating tract. Crayon attenuation varied by brand and color. All of the crayons demonstrated a signal void on T1 and T2 imaging and signal dropout on susceptibility-weighted imaging, the diameter of which varied by brand and color. Understanding the imaging appearance of crayons could help in the correct identification of a crayon as a foreign body on imaging studies, even when it is located in unusual places. (orig.)

A crayon fragment was determined to be the source of a foreign body inflammatory process in the masticator space of a 15-month-old boy. The appearance of the crayon on CT and MR imaging was unexpected, leading to a further analysis of the imaging features of crayons. To investigate and characterize the imaging appearance of crayons at CT and MRI. The authors obtained CT and MR images of 22 crayons from three manufacturers and three non-pigmented crayons cast by the authors. CT attenuation of the crayons and diameter of the MRI susceptibility signal dropout were plotted versus brand and color. All crayons demonstrated a longitudinal central hypo-attenuating tract. Crayon attenuation varied by brand and color. All of the crayons demonstrated a signal void on T1 and T2 imaging and signal dropout on susceptibility-weighted imaging, the diameter of which varied by brand and color. Understanding the imaging appearance of crayons could help in the correct identification of a crayon as a foreign body on imaging studies, even when it is located in unusual places. (orig.)

The purpose of this study was to explore LGBTQ women's experiences with unwritten or formal dress codes at work. I asked: What are LGBTQ women's experiences in the workplace with appearance management, and what are LGBTQ women's experiences navigating the written and unwritten dress codes in the workplace? To answer the research question, interviews were conducted with 24 self-identifying LGBTQ women. Six key themes emerged from the data. Themes included (1) expressed sexual identity in appearance, (2) unwritten dress codes in work environments did not always allow for expression of sexual identity in appearance, (3) motivations for pressure or desire to conceal expression of sexual identity in appearance at work, (4) negotiations of revealing or concealing sexual identity in appearance in the workplace impacted levels of comfort and confidence, (5) verbal and nonverbal negative experiences related to appearance at work, and (6) received compliments about appearance at work.

Investing in the ideal: does objectified body consciousness mediate the association between appearance contingent self-worth and appearance self-esteem in women?

Science.gov (United States)

Noser, Amy; Zeigler-Hill, Virgil

2014-03-01

Appearance contingent self-worth has been shown to be associated with low appearance self-esteem but little is known about the role that objectified body consciousness may play in this relationship. The purpose of the present study with 465 female undergraduates was to examine whether objectified body consciousness mediates the association between appearance contingent self-worth and low levels of appearance self-esteem. This was accomplished using a multiple mediation model to examine whether components of objectified body consciousness (i.e., body surveillance, body shame, and control beliefs) play unique roles in the connection between appearance contingent self-worth and appearance self-esteem. Results showed that body surveillance and body shame were significant mediators of the connection between appearance contingent self-worth and low levels of appearance self-esteem. Discussion focuses on the implications of these results for the ways in which appearance contingent self-worth may promote heightened body consciousness and possibly contribute to low levels of appearance self-esteem.

Masculinity, consumerism, and appearance: a look at men's hair.

Science.gov (United States)

Ricciardelli, Rosemary

2011-05-01

Historically, being concerned about appearance was stereotypically associated with women. Now masculinities too have become embedded in appearance norms. Consequently men too are increasingly concerned about their appearance. Via interviews with 14 Canadian men, the role of hair in self-identification and both satisfaction and dissatisfaction with appearance is examined. Emergent themes suggest that masculinity and appearance are increasingly intertwined, and consumer culture cultivates a climate that encourages men to view their appearance as something worthy of investment. Findings suggest that men are concerned about their appearance-specifically their hair-and that there is a relationship between masculinity, appearance, and self-identification. Findings are discussed within theories of masculinity and consumerism.

Subcutaneous granuloma annulare: radiologic appearance

International Nuclear Information System (INIS)

Kransdorf, M.J.; Murphey, M.D.; Temple, H.T.

1998-01-01

Objective. Granuloma annulare is an uncommon benign inflammatory dermatosis characterized by the formation of dermal papules with a tendency to form rings. There are several clinically distinct forms. The subcutaneous form is the most frequently encountered by radiologists, with the lesion presenting as a superficial mass. There are only a few scattered reports of the imaging appearance of this entity in the literature. We report the radiologic appearance of five cases of subcutaneous granuloma annulare. Design and patients. The radiologic images of five patients (three male, two female) with subcutaneous granuloma annulare were retrospectively studied. Mean patient age was 6.4 years (range, 2-13 years). The lesions occurred in the lower leg (two), foot, forearm, and hand. MR images were available for all lesions, gadolinium-enhanced imaging in three cases, radiographs in four, and bone scintigraphy in one. Results. Radiographs showed unmineralized nodular masses localized to the subcutaneous adipose tissue. The size range, in greatest dimension on imaging studies, was 1-4 cm. MR images show a mass with relatively decreased signal intensity on all pulse sequences, with variable but generally relatively well defined margins. There was extensive diffuse enhancement following gadolinium administration. Conclusion. The radiologic appearance of subcutaneous granuloma annulare is characteristic, typically demonstrating a nodular soft-tissue mass involving the subcutaneous adipose tissue. MR images show a mass with relatively decreased signal intensity on all pulse sequences and variable but generally well defined margins. There is extensive diffuse enhancement following gadolinium administration. Radiographs show a soft-tissue mass or soft-tissue swelling without evidence of bone involvement or mineralization. This radiologic appearance in a young individual is highly suggestive of subcutaneous granuloma annulare. (orig.)

Adolescent perceptions of cigarette appearance.

Ford, Allison; Moodie, Crawford; MacKintosh, Anne M; Hastings, Gerard

2014-06-01

To reduce the possibility of cigarette appearance misleading consumers about harm caused by the product, the European Commission's draft Tobacco Products Directive proposed banning cigarettes implied a more pleasant and palatable smoke for young smokers. A long brown cigarette was viewed as particularly unattractive and communicated a stronger and more harmful product. This exploratory study provides some support that standardising cigarette appearance could reduce the appeal of cigarettes in adolescents and reduce the opportunity for stick design to mislead young smokers in terms of harm. © The Author 2013.

A key intermediate in the biosynthetic pathway by which C(24) bile acids are formed from cholesterol has long been considered to be varanic acid, (24ξ,25ξ)-3α,7α,12α-24-tetrahydroxy-5β-cholestan-27-oic acid. The (24R,25R)-epimer of this tetrahydroxy bile acid, in the form of its taurine N-acyl amidate, was thought to be the major biliary bile acid in lizards of the family Varanidae. We report here that a major biliary bile acid of three lizard species - the Komodo dragon (Varanus komodoensis), Gray's monitor (Varanus olivaceus), and the Gila monster (Heloderma suspectum) - is a novel epimer of varanic acid. The epimer was shown to be (24R,25S)-3α,7α,12α,24-tetrahydroxy-5β-cholestan-27-oic acid (present in bile as its taurine conjugate). The structure was established by mass spectroscopy and by (1)H and (13)C nuclear magnetic spectroscopy, as well as by synthesis of the compound. Copyright © 2012 Elsevier Inc. All rights reserved.

Oncocytomas, called oxyphil proximal tubular adenomas in the Anglo Saxon literature, and benign hypernephromas are non-malignant, usually symptomless, rare tumours belonging to the renal adenomas. Oncocytomas have angiographic appearances sufficiently uniform to permit a tentative diagnosis. Histologically benign hypernephromas do not possess characteristic angiographic appearances and, in the presence of tumour in the renal vein or necrotic avascular areas, must be regarded as potentially malignant.

The average US adolescent is exposed to 34 references to alcohol in popular music daily. Although brand recognition is an independent, potent risk factor for alcohol outcomes among adolescents, alcohol brand appearances in popular music have not been assessed systematically. We aimed to determine the prevalence of and contextual elements associated with alcohol brand appearances in US popular music. Qualitative content analysis. We used Billboard Magazine to identify songs to which US adolescents were most exposed in 2005-07. For each of the 793 songs, two trained coders analyzed independently the lyrics of each song for references to alcohol and alcohol brand appearances. Subsequent in-depth assessments utilized Atlas.ti to determine contextual factors associated with each of the alcohol brand appearances. Our final code book contained 27 relevant codes representing six categories: alcohol types, consequences, emotional states, activities, status and objects. Average inter-rater reliability was high (κ = 0.80), and all differences were easily adjudicated. Of the 793 songs in our sample, 169 (21.3%) referred explicitly to alcohol, and of those, 41 (24.3%) contained an alcohol brand appearance. Consequences associated with alcohol were more often positive than negative (41.5% versus 17.1%, P brand appearances were associated commonly with wealth (63.4%), sex (58.5%), luxury objects (51.2%), partying (48.8%), other drugs (43.9%) and vehicles (39.0%). One in five songs sampled from US popular music had explicit references to alcohol, and one-quarter of these mentioned a specific alcohol brand. These alcohol brand appearances are associated commonly with a luxury life-style characterized by wealth, sex, partying and other drugs. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

A principal aim of computer graphics is to generate images that look as real as photographs. Realistic computer graphics imagery has however proven to be quite challenging to produce, since the appearance of materials arises from complicated physical processes that are difficult to analytically model and simulate, and image-based modeling of real material samples is often impractical due to the high-dimensional space of appearance data that needs to be acquired.This book presents a general framework based on the inherent coherency in the appearance data of materials to make image-based appeara

This paper reports the use of a mythic journey scenario within a student nurse groupwork session. This approach was introduced as a means to facilitate personal and interpersonal sharing and self-knowledge. These processes are held as important for the development of critical reflective process as a cornerstone of contemporary nursing practice. The use of myth invoked a coherent and supportive student environment within which previously reticent students appeared confident enough to contribute and explore their educational experience in nursing. The mythic allegoric process also identified some poignant themes and enemies, common across the student body. Monsters no less!

Memory and disgust: Effects of appearance-congruent and appearance-incongruent information on source memory for food.

Science.gov (United States)

Mieth, Laura; Bell, Raoul; Buchner, Axel

2016-01-01

The present study was stimulated by previous findings showing that people preferentially remember person descriptions that violate appearance-based first impressions. Given that until now all studies used faces as stimuli, these findings can be explained by referring to a content-specific module for social information processing that facilitates social orientation within groups via stereotyping and counter-stereotyping. The present study tests whether the same results can be obtained with fitness-relevant stimuli from another domain--pictures of disgusting-looking or tasty-looking food, paired with tasty and disgusting descriptions. A multinomial model was used to disentangle item memory, guessing and source memory. There was an old-new recognition advantage for disgusting-looking food. People had a strong tendency towards guessing that disgusting-looking food had been previously associated with a disgusting description. Source memory was enhanced for descriptions that disconfirmed these negative, appearance-based impressions. These findings parallel the results from the social domain. Heuristic processing of stimuli based on visual appearance may be complemented by intensified processing of incongruent information that invalidates these first impressions.

UGC galaxies in the declination band +5 to +75 deg were identified by position coincidence with radio sources stronger than 25 mJy on the Green Bank 4.85 GHz sky maps. Candidate identifications were confirmed or rejected with the aid of published aperture-synthesis maps and new 4.86 GHz VLA maps having 15 or 18 arcsec resolution, resulting in a sample of 347 nearby radio galaxies plus five new quasar-galaxy pairs. The radio energy sources in UGC galaxies were classified as starbursts or monsters on the basis of their infrared-radio flux ratios, infrared spectral indices, and radio morphologies. The rms scatter in the logarithmic infrared-radio ratio q is not more than 0.16 for starburst galaxies selected at 4.85 GHz. Radio spectral indices were obtained for nearly all of the UGC galaxies, and S0 galaxies account for a disproportionate share of the compact flat-spectrum (alpha less than 0.5) radio sources. The extended radio jets and lobes produced by monsters are preferentially, but not exclusively, aligned within about 30 deg of the optical minor axes of their host galaxies. The tendency toward minor-axis ejection appears to be independent of radio-source size and is strongest for elliptical galaxies. 230 refs

MR appearance of central neurocytoma

1993-01-01

To provide a detailed description of the MR appearances of central neurocytoma, MR images of 13 patients with central neurocytoma were retrospectively reviewed and compared with CT examinations. The histology was confirmed by ultrastructural and immunohistochemical studies. In 12 patients the tumors were histologically benign and located in the anterior part of the lateral ventricle, 6 of which extended to the 3rd ventricle. There was one case of a histologically malignant variant involving the thalamus and lateral ventricle. The tumors were primarily solid, but contained cysts (85%, 11/13), calcifications (69%, 9/13), and signal void from tumor vessels (62%, 8/13), frequently producing heterogeneous signal intensity on both T1- and T2-weighted images. Most of the solid portion appeared isointense or slightly hyperintense relative to the cerebral cortex on all MR pulse sequences. Calcifications were iso- or hypointense on MR, making them difficult to characterize with MR alone. Intratumoral hemorrhage was seen in 2 patients on MR but not on CT. Contrast enhancement was variable in degree and pattern. Coronal and sagittal MR images were valuable in evaluating the tumor extent and origin site, and in planning the surgical approach. It is concluded that MR imaging appears to be more useful than CT in the overall evaluation of central neurocytoma, even though calcification is better characterized with CT. (orig.)

Color categories and color appearance

Science.gov (United States)

Webster, Michael A.; Kay, Paul

2011-01-01

We examined categorical effects in color appearance in two tasks, which in part differed in the extent to which color naming was explicitly required for the response. In one, we measured the effects of color differences on perceptual grouping for hues that spanned the blue–green boundary, to test whether chromatic differences across the boundary were perceptually exaggerated. This task did not require overt judgments of the perceived colors, and the tendency to group showed only a weak and inconsistent categorical bias. In a second case, we analyzed results from two prior studies of hue scaling of chromatic stimuli (De Valois, De Valois, Switkes, & Mahon, 1997; Malkoc, Kay, & Webster, 2005), to test whether color appearance changed more rapidly around the blue–green boundary. In this task observers directly judge the perceived color of the stimuli and these judgments tended to show much stronger categorical effects. The differences between these tasks could arise either because different signals mediate color grouping and color appearance, or because linguistic categories might differentially intrude on the response to color and/or on the perception of color. Our results suggest that the interaction between language and color processing may be highly dependent on the specific task and cognitive demands and strategies of the observer, and also highlight pronounced individual differences in the tendency to exhibit categorical responses.

Exposure to advertisements cannot fully explain the associations between young children's dietary intake and the time they spend in front of the television. It is therefore of importance to study television content other than advertisements in this aspect. The present study aimed to examine the nature and extent of verbal and visual appearances of foods and beverages in children's television programmes on Icelandic public service television. A total of 27 h of children's programmes (domestic and internationally produced) were watched. All verbal and visual appearances of foods and beverages were coded, as well as the context in which the foods/beverages were discussed or appeared. Children's programmes on Icelandic public service television. Two food groups were of special interest for their importance from a public health perspective: high-calorie and low-nutrient (HCLN) foods and fruits and vegetables (F&V). The χ 2 test and logistic regression were performed to analyse if the occurrence of the two groups was associated with the context where foods/beverages appeared. Of the 125 different programmes, a food or beverage appeared in 86 %. Of the total food appearances (n 599), HCLN foods accounted for 26 % and F&V for 23 %. HCLN foods were presented as desirable by appearing more frequently with child characters (Pfood and eating is presented in children's programmes, as young childhood is a critical period for founding healthy habits for later life.

Selecting fillers on emotional appearance improves lineup identification accuracy.

Science.gov (United States)

Flowe, Heather D; Klatt, Thimna; Colloff, Melissa F

2014-12-01

Mock witnesses sometimes report using criminal stereotypes to identify a face from a lineup, a tendency known as criminal face bias. Faces are perceived as criminal-looking if they appear angry. We tested whether matching the emotional appearance of the fillers to an angry suspect can reduce criminal face bias. In Study 1, mock witnesses (n = 226) viewed lineups in which the suspect had an angry, happy, or neutral expression, and we varied whether the fillers matched the expression. An additional group of participants (n = 59) rated the faces on criminal and emotional appearance. As predicted, mock witnesses tended to identify suspects who appeared angrier and more criminal-looking than the fillers. This tendency was reduced when the lineup fillers matched the emotional appearance of the suspect. Study 2 extended the results, testing whether the emotional appearance of the suspect and fillers affects recognition memory. Participants (n = 1,983) studied faces and took a lineup test in which the emotional appearance of the target and fillers was varied between subjects. Discrimination accuracy was enhanced when the fillers matched an angry target's emotional appearance. We conclude that lineup member emotional appearance plays a critical role in the psychology of lineup identification. The fillers should match an angry suspect's emotional appearance to improve lineup identification accuracy. PsycINFO Database Record (c) 2014 APA, all rights reserved.

Reflectance, illumination, and appearance in color constancy.

McCann, John J; Parraman, Carinna; Rizzi, Alessandro

2014-01-01

We studied color constancy using a pair of identical 3-D Color Mondrian displays. We viewed one 3-D Mondrian in nearly uniform illumination, and the other in directional, nonuniform illumination. We used the three dimensional structures to modulate the light falling on the painted surfaces. The 3-D structures in the displays were a matching set of wooden blocks. Across Mondrian displays, each corresponding facet had the same paint on its surface. We used only 6 chromatic, and 5 achromatic paints applied to 104 block facets. The 3-D blocks add shadows and multiple reflections not found in flat Mondrians. Both 3-D Mondrians were viewed simultaneously, side-by-side. We used two techniques to measure correlation of appearance with surface reflectance. First, observers made magnitude estimates of changes in the appearances of identical reflectances. Second, an author painted a watercolor of the 3-D Mondrians. The watercolor's reflectances quantified the changes in appearances. While constancy generalizations about illumination and reflectance hold for flat Mondrians, they do not for 3-D Mondrians. A constant paint does not exhibit perfect color constancy, but rather shows significant shifts in lightness, hue and chroma in response to the structure in the nonuniform illumination. Color appearance depends on the spatial information in both the illumination and the reflectances of objects. The spatial information of the quanta catch from the array of retinal receptors generates sensations that have variable correlation with surface reflectance. Models of appearance in humans need to calculate the departures from perfect constancy measured here. This article provides a dataset of measurements of color appearances for computational models of sensation.

Ursine hibernation uniquely combines prolonged skeletal unloading, anuria, pregnancy, lactation, protein recycling, and lipolysis. This study presents a radiographic and biochemical picture of bone metabolism in free-ranging, female American black bears (Ursus americanus) that were active (spring bears and autumn bears) or hibernating (hibernating bears). Hibernating bears included lactating and non-lactating individuals. We measured serum calcium, albumin, inorganic phosphate, creatinine, bone specific alkaline phosphatase (BSALP), CTX, parathyroid hormone, insulin-like growth factor-I (IGF-l), leptin, 25-hydroxyvitamin D [25(OH)D], 1,25-dihydroxyvitamin D [1,25(OH)(2)D] and sclerostin from 35 to 50 tranquilized hibernating bears and 14 to 35 tranquilized spring bears. We compared metacarpal cortical indices (MCI), measured by digital X-ray radiogrammetry, from 60 hunter-killed autumn bears and 79 tranquilized, hibernating bears. MCI was greater in autumn than winter in younger bears, but showed no seasonal difference in older bears. During hibernation eucalcemia was maintained, BSALP was suppressed, and CTX was in the range expected for anuria. During hibernation 1,25(OH)(2)D was produced despite anuria. 1,25(OH)(2)D and IGF-I were less in hibernating than spring bears. In a quarter of hibernating bears, sclerostin was elevated. Leptin was greater in hibernating than spring bears. In hibernating bears, leptin correlated positively with BSALP in non-lactating bears and with CTX in lactating bears. Taken together the biochemical and radiographic findings indicate that during hibernation, bone turnover was persistent, balanced, and suppressed; bone resorption was lower than expected for an unloaded skeleton; and there was no unloading-induced bone loss. The skeleton appears to perceive that it was loaded when it was actually unloaded during hibernation. However, at the level of sclerostin, the skeleton recognized that it was unloaded. During hibernation leptin

Uterine fibroids, also known as leiomyomas, are the most common uterine neoplasms. Although benign, they can be associated with significant morbidity and are the commonest indication for hysterectomy. They are often discovered incidentally when performing imaging for other reasons. Usually first identified with US, they can be further characterized with MRI. They are usually easily recognizable, but degenerate fibroids can have unusual appearances. Knowledge of the different appearances of fibroids on imaging is important as it enables prompt diagnosis and thereby guides treatment. (authors)

Metasynthetic Madness: What Kind of Monster Have We Created?

Science.gov (United States)

Thorne, Sally

2017-01-01

From its origins in the 1990s, the qualitative health research metasynthesis project represented a methodological maneuver to capitalize on a growing investment in qualitatively derived study reports to create an interactive dialogue among them that would surface expanded insights about complex human phenomena. However, newer forms positioning themselves as qualitative metasynthesis but representing a much more technical and theoretically superficial form of scholarly enterprise have begun to appear in the health research literature. It seems imperative that we think through the implications of this trend and determine whether it is to be afforded the credibility of being a form of qualitative scholarship and, if so, what kind of scholarship it represents. As the standardization trend in synthesis research marches forward, we will need clarity and a strong sense of purpose if we are to preserve the essence of what the qualitative metasynthesis project was intended to be all about. © The Author(s) 2016.

Meal consumption is ineffective at maintaining or correcting water balance in a desert lizard, Heloderma suspectum.

Wright, Christian D; Jackson, Marin L; DeNardo, Dale F

2013-04-15

Many xeric organisms maintain water balance by relying on dietary and metabolic water rather than free water, even when free water may be available. For such organisms, hydric state may influence foraging decisions, since meal consumption is meeting both energy and water demands. To understand foraging decisions it is vital to understand the role of dietary water in maintaining water balance. We investigated whether meal consumption was sufficient to maintain water balance in captive Gila monsters (Heloderma suspectum) at varying levels of dehydration. Gila monsters could not maintain water balance over long time scales through meal consumption alone. Animals fed a single meal took no longer to dehydrate than controls when both groups were deprived of free water. Additionally, meal consumption imparts an acute short-term hydric cost regardless of hydration state. Meal consumption typically resulted in a significant elevation in osmolality at 6 h post-feeding, and plasma osmolality never fell below pre-feeding levels despite high water content (~70%) of meals. These results failed to support our hypothesis that dietary water is valuable to Gila monsters during seasonal drought. When considered in conjunction with previous research, these results demonstrate that Gila monsters, unlike many xeric species, are heavily reliant on seasonal rainfall and the resulting free-standing water to maintain water balance.

Objective: To describe the MRI features of nodular fasciitis and to review the clinical, MRI and histologic aspects of the tumor. Design and patients: Three patients with biopsy-proven nodular fasciitis were selected for a retrospective study. A literature review was also carried out. Results and conclusions: All the lesions appeared slightly hyperintense to skeletal muscle on T1-weighted images, and hyperintense on T2-weighted images with fat saturation [either frequency saturation or Short TI Inversion Recovery (STIR) sequences]. Two enhanced homogeneously after intravenous gadolinium, whereas the third showed heterogeneous enhancement with a nonenhancing area. Despite the difference in enhancing patterns, the histologic appearances of these lesions were similar. Our study shows that the MRI appearance of nodular fasciitis may not be related to the location of lesion. It is thought that the age of nodular fasciitis may reflect its gross morphology, and it is possible that the MRI and histologic appearances could correlate with the age of the lesion, but it would require a larger series to evaluate this concept.

The Taiwanese Derriford Appearance Scale: The translation and validation of a scale to measure individual responses to living with problems of appearance.

Science.gov (United States)

Moss, Timothy Peter; Lawson, Victoria; Liu, Chiu Ying

2015-09-01

The extent of concern about physical appearance is increasingly the subject of scientific study, interventions by health professionals, and media attention. To enable carefully evaluated studies exploring the psychosocial antecedents of appearance distress, and to determine the success of interventions, the Derriford Appearance Scale 24 (DAS24) was developed. This psychometrically sound measure is well used and cited in the appearance psychology field. Outside of a Western context, the extent and impact of appearance distress is less well known. This paper describes the adaptation of the DAS24 for use in Taiwan. A formal translation protocol was followed to adapt the DAS24 into Taiwanese/Cantonese. Two hundred and eight participants from a general population and a visibly different population were recruited in Taipei, Taiwan. These participants completed a test pack administered comprising the translated DAS24, and established measures of anxiety and depression. The scale was analyzed on the basis of classical test theory. A translated DAS Scale comprising 19 items and including three clear factors was the best solution. The scale had good internal consistency, clear convergent validity, and good test-retest reliability. The three factors that emerged were appearance-related social avoidance, social distress, and negative affect. Consistent with expectations, (a) women scored higher than men (greater appearance distress), (b) the cause of appearance difference (burns, cleft lip/palate, etc.) was unrelated to appearance distress, and (c) those with visible differences were more concerned about their appearance than those without. The Taiwanese DAS19 is a user-friendly and psychometrically sound scale that fulfils an important clinical and scientific need. The items that were omitted from the translated version were considered in relation to cultural differences in the experience and expression of shame between Western countries and Taiwan/China, which demands a

Aims The average US adolescent is exposed to 34 references to alcohol in popular music daily. Although brand recognition is an independent, potent risk factor for alcohol outcomes among adolescents, alcohol brand appearances in popular music have not been systematically assessed. We aimed to determine the prevalence of and contextual elements associated with alcohol brand appearances in U.S. popular music. Design Qualitative content analysis. Setting We used Billboard Magazine to identify songs to which US adolescents were most exposed in 2005-2007. For each of the 793 songs, two trained coders independently analyzed the lyrics of each song for references to alcohol and alcohol brand appearances. Subsequent in-depth assessments utilised Atlas.ti to determine contextual factors associated with each of the alcohol brand appearances. Measurements Our final code book contained 27 relevant codes representing 6 categories: alcohol types, consequences, emotional states, activities, status, and objects. Findings Average inter-rater reliability was high (κ=0.80), and all differences were easily adjudicated. Of the 793 songs in our sample, 169 (21.3%) explicitly referred to alcohol, and of those, 41 (24.3%) contained an alcohol brand appearance. Consequences associated with alcohol were more often positive than negative (41.5% vs. 17.1%, Pbrand appearances were commonly associated with wealth (63.4%), sex (58.5%), luxury objects (51.2%), partying (48.8%), other drugs (43.9%), and vehicles (39.0%). Conclusions One-in-five songs sampled from U.S. popular music had explicit references to alcohol, and one quarter of these mentioned a specific alcohol brand. These alcohol brand appearances are commonly associated with a luxury lifestyle characterised by wealth, sex, partying, and other drugs. PMID:22011113

This study investigated the associations of appearance orientation and eating disorder symptoms with internal body awareness in an eating-disordered group of women and a general sample of women. In the eating-disordered group, appearance orientation was positively associated with internal body awareness. Eating disorders symptoms were negatively related to the awareness of bodily signals. No significant associations were found in the general sample of women. The results indicate that in eating-disordered individuals preoccupation with the body and eating-disordered behaviors are not only negatively associated with hunger, but with awareness of other bodily signals as well.

Fast Appearance Modeling for Automatic Primary Video Object Segmentation.

Yang, Jiong; Price, Brian; Shen, Xiaohui; Lin, Zhe; Yuan, Junsong

2016-02-01

Automatic segmentation of the primary object in a video clip is a challenging problem as there is no prior knowledge of the primary object. Most existing techniques thus adapt an iterative approach for foreground and background appearance modeling, i.e., fix the appearance model while optimizing the segmentation and fix the segmentation while optimizing the appearance model. However, these approaches may rely on good initialization and can be easily trapped in local optimal. In addition, they are usually time consuming for analyzing videos. To address these limitations, we propose a novel and efficient appearance modeling technique for automatic primary video object segmentation in the Markov random field (MRF) framework. It embeds the appearance constraint as auxiliary nodes and edges in the MRF structure, and can optimize both the segmentation and appearance model parameters simultaneously in one graph cut. The extensive experimental evaluations validate the superiority of the proposed approach over the state-of-the-art methods, in both efficiency and effectiveness.

Full Text Available Objective. To identify participants’ satisfaction with appearance and the desired treatment to improve aesthetics. Materials and Methods. 220 participants (127 males and 93 females, mean age = 21.4 ± 1.5 years were recruited into the study. A structured questionnaire was used to assess patients’ satisfaction with appearance and what treatment they desire to improve aesthetics. Participants scored the level of satisfaction with appearance using visual analogue scale. Results. The VAS mean score of satisfaction with general appearance was 6.8 ± 2.3. Half participants were dissatisfied with tooth appearance and 65.9% were dissatisfied with tooth colour. Higher VAS scores were associated with higher desire for all treatments that improve tooth appearance (. Dissatisfaction with tooth appearance increased with increased dissatisfaction with teeth colour, feeling of poor tooth alignment, presence of fractured anterior teeth, and increased desire for orthodontic, crowns, and dentures treatments (. Dissatisfaction with tooth colour was associated with increased desire for tooth whitening and tooth coloured fillings (. Conclusions. Participants had high levels of dissatisfaction with tooth appearance and tooth colour. Dissatisfaction with tooth colour contributed to the increased dissatisfaction with tooth appearance. Dissatisfaction with tooth appearance, colour, alignment, and condition was significantly related to high desire for aesthetic treatments.

Owl's eye appearance: a case report

Mathur, Mukul; Asha, P.

2010-01-01

Full text: Hyper-functioning thyroid nodule may present various scintigraphic appearances on thyroid scans. Autonomously hyper functioning thyroid nodules often show degenerative changes. These changes may give rise to peripheral photopenic areas on a thyroid scan. In this report we present a case of hyper functioning nodule showing appearance of an owl's eye. Although rare, such pattern can be seen in a variety of benign and malignant thyroid conditions. A 42-year-old man presented with a solitary thyroid nodule in the right lobe and weight loss for four months. The thyroid hormone profile confirmed hyperthyroidism. Thyroid function testing revealed T4=136.8 nmol/l (Normal = 66.0-181.0 nmol/L) and Thyroid Stimulating Hormone (TSH) = 0.283 (Normal =0.27- 4.2 μIU/ml). Antithyroglobulin antibodies and antimicrosmal antibodies were negative. The patient was referred for thyroid scan and uptake. A Thyroid scan was obtained after the intravenous injection of 5 mCi (185MBq) of 99m Tc pertechnetate. Anterior view obtained using a parallel hole collimator. The scan showed peripheral photopenic area with a central focal area of increased uptake giving the appearance of 'Owl's eye'. 99m Tc-pertechnetate uptake was increased. A scintigraphic 'Owl's eye' sign has been described in thyroid cyst, benign autonomous nodule and papillary carcinoma of the thyroid gland. This Owl's eye pattern appears to be caused by a focus of functioning tissue overlapping a large cold area in a nodule that has cystic,degenerative and necrotic changes in the middle of a benign and malignant pathology. Hyper functioning nodules may scintigraphically show Owl's eye pattern due to intra nodular degeneration, with residual hyper functioning tissue within or overlapping the degenerative area

We investigate the influence of the visual appearance of a negotiator on persuasiveness within the context of negotiations. Psychological experiments were conducted to quantitatively analyze the relationship between visual appearance and the use of language. Male and female participants were shown three female and male photographs, respectively. They were asked to report how they felt about each photograph using a seven-point semantic differential (SD) scale for six affective factors (positive impression, extraversion, intelligence, conscientiousness, emotional stability, and agreeableness). Participants then answered how they felt about each negotiation scenario (they were presented with pictures and a situation combined with negotiation sentences) using a seven-point SD scale for seven affective factors (positive impression, extraversion, intelligence, conscientiousness, emotional stability, agreeableness, and degree of persuasion). Two experiments were conducted using different participant groups depending on the negotiation situations. Photographs with good or bad appearances were found to show high or low degrees of persuasion, respectively. A multiple regression equation was obtained, indicating the importance of the three language factors (euphemistic, honorific, and sympathy expressions) to impressions made during negotiation. The result shows that there are optimal negotiation sentences based on various negotiation factors, such as visual appearance and use of language. For example, persons with good appearance might worsen their impression during negotiations by using certain language, although their initial impression was positive, and persons with bad appearance could effectively improve their impressions in negotiations through their use of language, although the final impressions of their negotiation counterpart might still be more negative than those for persons with good appearance. In contrast, the impressions made by persons of normal appearance

If the correct interpretation of the Super-Kamiokande atmospheric neutrino data is ν μ → ν τ oscillation, the contained data sample should already have more than 10 τ appearance events. We study the challenging task of detecting the τ, focusing on the decay chain τ ± → ρ ± → π ± π 0 in events with quasi-elastic τ production. The background level, which is currently quite uncertain because of a lack of relevant neutral current data, can be measured by the near detector in the K2K experiment. Our estimates of the background suggest that it may be possible to detect τ appearance in Super-Kamiokande with 5-10 years of running

Gender dysphoria (GD) is often accompanied by dissatisfaction with physical appearance and body image problems. The aim of this study was to compare body satisfaction with perceived appearance by others in various GD subgroups. Data collection was part of the European Network for the Investigation of Gender Incongruence. Between 2007 and 2012, 660 adults who fulfilled the criteria of the DSM-IV gender identity disorder diagnosis (1.31:1 male-to-female [MtF]:female-to-male [FtM] ratio) were included into the study. Data were collected before the start of clinical gender-confirming interventions. Sexual orientation was measured via a semi-structured interview whereas onset age was based on clinician report. Body satisfaction was assessed using the Body Image Scale. Congruence of appearance with the experienced gender was measured by means of a clinician rating. Overall, FtMs had a more positive body image than MtFs. Besides genital dissatisfaction, problem areas for MtFs included posture, face, and hair, whereas FtMs were mainly dissatisfied with hip and chest regions. Clinicians evaluated the physical appearance to be more congruent with the experienced gender in FtMs than in MtFs. Within the MtF group, those with early onset GD and an androphilic sexual orientation had appearances more in line with their gender identity. In conclusion, body image problems in GD go beyond sex characteristics only. An incongruent physical appearance may result in more difficult psychological adaptation and in more exposure to discrimination and stigmatization.

An important factor in social interaction is physical appearance. Major elements in the evaluation of physical appearance are the mouth and teeth. The purpose of this study was to evaluate the effect of tooth appearance on the development of a first impression of the other person, with regard to the sex of both the respondent and the target. Eight facial photographs of individuals with intact upper teeth were manipulated: one set was left untouched and the other was professionally altered so that the front anterior teeth appeared decayed. The photographs were randomly aligned in sets of eight, each set consisting of four individuals with an original, intact dentition and four other individuals with a "decayed" dentition. The sets of photographs were then presented to 115 respondents (65 males and 50 females). Evaluations were made according to three categories of traits--esthetic, social, and professional. For all three evaluation categories, the difference in scores between decayed and intact dentition given to targets were significantly higher when participants of one sex evaluated targets of the opposite sex, as compared to evaluating targets of their own sex. The effect of tooth appearance on the physical attractiveness stereotype is more evident when males evaluate females and vice versa, rather than when evaluating their own sex.

In this positional paper, we discuss the potential benefits of using appearance models in additive manufacturing, metal casting, wind turbine blade production, and 3D content acquisition. Current state of the art in acquisition and rendering of appearance cannot easily be used for quality assurance...... in these areas. The common denominator is the need for descriptive and parsimonious appearance models. By ‘parsimonious’ we mean with few parameters so that a model is useful both for fast acquisition, robust fitting, and fast rendering of appearance.

Active appearance pyramids for object parametrisation and fitting.

Science.gov (United States)

Zhang, Qiang; Bhalerao, Abhir; Dickenson, Edward; Hutchinson, Charles

2016-08-01

Object class representation is one of the key problems in various medical image analysis tasks. We propose a part-based parametric appearance model we refer to as an Active Appearance Pyramid (AAP). The parts are delineated by multi-scale Local Feature Pyramids (LFPs) for superior spatial specificity and distinctiveness. An AAP models the variability within a population with local translations of multi-scale parts and linear appearance variations of the assembly of the parts. It can fit and represent new instances by adjusting the shape and appearance parameters. The fitting process uses a two-step iterative strategy: local landmark searching followed by shape regularisation. We present a simultaneous local feature searching and appearance fitting algorithm based on the weighted Lucas and Kanade method. A shape regulariser is derived to calculate the maximum likelihood shape with respect to the prior and multiple landmark candidates from multi-scale LFPs, with a compact closed-form solution. We apply the 2D AAP on the modelling of variability in patients with lumbar spinal stenosis (LSS) and validate its performance on 200 studies consisting of routine axial and sagittal MRI scans. Intervertebral sagittal and parasagittal cross-sections are typically used for the diagnosis of LSS, we therefore build three AAPs on L3/4, L4/5 and L5/S1 axial cross-sections and three on parasagittal slices. Experiments show significant improvement in convergence range, robustness to local minima and segmentation precision compared with Constrained Local Models (CLMs), Active Shape Models (ASMs) and Active Appearance Models (AAMs), as well as superior performance in appearance reconstruction compared with AAMs. We also validate the performance on 3D CT volumes of hip joints from 38 studies. Compared to AAMs, AAPs achieve a higher segmentation and reconstruction precision. Moreover, AAPs have a significant improvement in efficiency, consuming about half the memory and less than 10% of

Webster, Michael A.; Kay, Paul

2012-01-01

We examined categorical effects in color appearance in two tasks, which in part differed in the extent to which color naming was explicitly required for the response. In one, we measured the effects of color differences on perceptual grouping for hues that spanned the blue-green boundary, to test whether chromatic differences across the boundary…

Optical appearance of distant galaxies

International Nuclear Information System (INIS)

Pritchet, C.; Kline, M.I.

1981-01-01

We have used the recent evolutionary and K-corrections of Bruzual and Kron to predict the optical appearance of galaxies spanning a wide range of magnitudes and redshifts. It is found that nearly all galaxies with J< or approx. =25 are resolved in 1-arcsec seeing. At fixed apparent magnitude, galaxies with large redshifts are more diffuse in appearance than those at small z. This fact causes the most distant galaxies at any magnitude level to be missed, and, depending on the measurement algorithm employed, may cause the luminosities of detected galaxies to be seriously underestimated. Both of these effects deserve consideration when attempting to interpret number counts of faint galaxies. Observations made with the Space Telescope are expected to resolve nearly all galaxies at J< or approx. =27.5; however, several factors conspire to render Space Telescope observations less effective than certain ground-based CCD observations for the optical detection of distant galaxies. Finally, we note that most of our conclusions are unaffected by changes in the assumed cosmology

Wavelet Enhanced Appearance Modelling

DEFF Research Database (Denmark)

2004-01-01

Generative segmentation methods such as the Active Appearance Models (AAM) establish dense correspondences by modelling variation of shape and pixel intensities. Alas, for 3D and high-resolution 2D images typical in medical imaging, this approach is rendered infeasible due to excessive storage......-7 wavelets on face images have shown that segmentation accuracy degrades gracefully with increasing compression ratio. Further, a proposed weighting scheme emphasizing edges was shown to be significantly more accurate at compression ratio 1:1, than a conventional AAM. At higher compression ratios the scheme...

Memory colours affect colour appearance.

Science.gov (United States)

Witzel, Christoph; Olkkonen, Maria; Gegenfurtner, Karl R

2016-01-01

Memory colour effects show that colour perception is affected by memory and prior knowledge and hence by cognition. None of Firestone & Scholl's (F&S's) potential pitfalls apply to our work on memory colours. We present a Bayesian model of colour appearance to illustrate that an interaction between perception and memory is plausible from the perspective of vision science.

Exotic primitivism of death in classical Hollywood living dead films

Directory of Open Access Journals (Sweden)

Outi Hakola

2012-11-01

Full Text Available http://dx.doi.org/10.5007/2175-8026.2012n62p219 The classical Hollywood horror exhibited the undead monsters, such as mummies, zombies and vampires, at the time when cultural practices of death and dying were changing in the United States. Consequently, the way death is handled in these films is connected to the ongoing marginalization of death. In the classical films, heroes represent modern, medicalized, scientific and marginalized death. In contrast, the undead represent traditional, or irrational and magical, death. When the heroes hunt down and kill the monsters, they also claim the superiority of modern death. Furthermore, the exclusion of traditional death is highlighted by using (postcolonial tensions. The non-western monsters and realm of the world stand for traditional death and the past whereas western heroes represent modern death and the future. This article concentrates on how the classical living dead films narrate the cultural tension between the waning (traditional and emerging (modern practices of death.

Prior, Suzanne M; Fenwick, Kimberley D; Peterson, Jasmine C

2014-01-01

We examined adolescents' reasons for tanning and how these relate to appearance evaluation and orientation. Two hundred and sixty-four Canadian adolescents (age range 15-19 years) in grades 10, 11, and 12 completed a survey that included scales measuring their reasons for tanning, appearance evaluation, and appearance orientation. It was found that girls and boys differed on four of nine subscales measuring reasons for tanning. Girls believed more strongly than boys that tanning improved their general appearance and that friends influenced their decision to tan. Girls also expressed less concern than boys that tanning caused immediate skin damage or premature aging. The pattern of correlations between the reasons for tanning and appearance orientation was similar for girls and boys. For both, appearance reasons for tanning and sociocultural influences on tanning were positively associated with appearance orientation. Suggestions for future research with adolescents and a proposal for a guiding model are provided. Copyright © 2013 Elsevier Ltd. All rights reserved.

Modeling self-occlusions in dynamic shape and appearance tracking

KAUST Repository

Yang, Yanchao

2013-12-01

We present a method to track the precise shape of a dynamic object in video. Joint dynamic shape and appearance models, in which a template of the object is propagated to match the object shape and radiance in the next frame, are advantageous over methods employing global image statistics in cases of complex object radiance and cluttered background. In cases of complex 3D object motion and relative viewpoint change, self-occlusions and disocclusions of the object are prominent, and current methods employing joint shape and appearance models are unable to accurately adapt to new shape and appearance information, leading to inaccurate shape detection. In this work, we model self-occlusions and dis-occlusions in a joint shape and appearance tracking framework. Experiments on video exhibiting occlusion/dis-occlusion, complex radiance and background show that occlusion/dis-occlusion modeling leads to superior shape accuracy compared to recent methods employing joint shape/appearance models or employing global statistics. © 2013 IEEE.

Endometrial ablation: normal appearance and complications.

Science.gov (United States)

Drylewicz, Monica R; Robinson, Kathryn; Siegel, Cary Lynn

2018-03-14

Global endometrial ablation is a commonly performed, minimally invasive technique aimed at improving/resolving abnormal uterine bleeding and menorrhagia in women. As non-resectoscopic techniques have come into existence, endometrial ablation performance continues to increase due to accessibility and decreased requirements for operating room time and advanced technical training. The increased utilization of this method translates into increased imaging of patients who have undergone the procedure. An understanding of the expected imaging appearances of endometrial ablation using different modalities is important for the abdominal radiologist. In addition, the frequent usage of the technique naturally comes with complications requiring appropriate imaging work-up. We review the expected appearance of the post-endometrial ablated uterus on multiple imaging modalities and demonstrate the more common and rare complications seen in the immediate post-procedural time period and remotely.

The purpose of this study was to determine the initial appearance of lung adenocarcinoma on computed tomography and the appropriate follow-up duration. Retrospective review of 17 cases in which computed tomography (CT) of the chest was performed about 2 years prior to the diagnosis of lung cancer. The diagnosis was confirmed by surgical resection in all cases. The lung cancers were divided into four types based on their appearance on the initial CT: ground-glass opacity (GGO)-like images in which the lesion appeared as a faint opacity, BLA (bubble-like appearance) image, in which the lesion resembled a focal collection of air, a small solitary nodule, and a scar-like image. Vascular involvement, air-bronchogram, and pleural indentation were all more prominent during a serial scan obtained just prior to surgery than on the initial scan. An increase in vascular involvement occurred prior to the other changes. High attenuation areas appeared in the GGO-like lesions prior to an increase in the size of the lesion. The growth pattern was classified as slow growing, rapidly growing, and initially slow growing with accelerated growth. The doubling time was similar in lesions with the same appearance. This information can be used to guide follow-up of images suspected of lung cancer. The appropriate follow-up duration is estimated from 6 to 12 months for GGO and BLA-like images, and from 2 to 3 months for small solitary nodules. The biological behavior of lung cancer is reflected in their initial appearance on CT. (author)

A defining feature of mental health courts (MHCs) is the requirement that enrollees appear periodically for status review hearings before the MHC judge. Although the research base on these specialty courts is growing, MHC appearances have yet to be examined. In the present study, the authors followed more than 400 MHC clients from four courts. We examined the number of court appearances that were mandated versus attended, the number of bench warrants issued, and the proportion of court appearances that were made in-custody versus out-of-custody. Finally, we describe and report on the proportion of clients at each court who had graduated, had been terminated, or who were still in the court one year following enrollment.

Issues in the management of acute agitation: how much current guidelines consider safety?

Directory of Open Access Journals (Sweden)

Bruno ePacciardi

2013-05-01

Full Text Available Agitated behavior constitutes up to 10% of emergency psychiatric interventions. Pharmacological tranquilization is often used as a valid treatment for agitation but a strong evidence base does not underpin it. Available literature shows different recommendations, supported by research data, theoretical considerations or clinical experience. Rapid tranquilization is mainly based on parenteral drug treatment and the few existing guidelines on this topic, when suggesting the use of first generation antipsychotics and benzodiazepines, include drugs with questionable tolerability profile such as chlorpromazine, haloperidol, midazolam and lorazepam. In order to systematically evaluate safety concerns related to the adoption of such guidelines, we reviewed them independently from principal diagnosis while examining tolerability data for suggested treatments. There is a growing evidence about safety profile of second generation antipsychotics for rapid tranquilization but further controlled studies providing definitive data in this area are urgently needed.

Objective. To identify participants' satisfaction with appearance and the desired treatment to improve aesthetics. Materials and Methods. 220 participants (127 males and 93 females, mean age = 21.4 ± 1.5 years) were recruited into the study. A structured questionnaire was used to assess patients' satisfaction with appearance and what treatment they desire to improve aesthetics. Participants scored the level of satisfaction with appearance using visual analogue scale. Results. The VAS mean score of satisfaction with general appearance was 6.8 ± 2.3. Half participants were dissatisfied with tooth appearance and 65.9% were dissatisfied with tooth colour. Higher VAS scores were associated with higher desire for all treatments that improve tooth appearance (P feeling of poor tooth alignment, presence of fractured anterior teeth, and increased desire for orthodontic, crowns, and dentures treatments (P desire for tooth whitening and tooth coloured fillings (P desire for aesthetic treatments.

The very rare benign chondroblastoma occasionally invades soft tissues and may grow beyond the epiphysis into the metaphysis. In the present case such a tumour did not show the typical radiological appearances, but presented malignant features both on plain films and on the angiogram. The importance of biopsy of tumours which cannot be identified with certainty must be stressed before radical surgery is carried out.

Objective: To investigate the CT appearance and features of tubal pregnancy. Methods: Precontrast and postcontrast CT scans were employed in 38 patients who were clinically and ultrasonographically suspected of tubal pregnancy. 34 of them were verified as tubal pregnancy through operative pathology. Results: 1. The direct CT imaging feature was the whole pregnancies sac (4/34, 11.8%) or half-baked pregnancies sac (14/34, 41.2%); 2. The indirect CT imaging features were: (1) abnormal density image, which could be enhanced, in a cystic mass around adnexal area (8/34, 23.5%); (2) mix density mass around adnexal area, which was mainly solid and had mild to moderate inhomogeneous enhancement (19/34, 55.9%); (3) large area irregular shadow with high density were found beside the uterus, with no enhancement (3/34, 8.8%). (4) bloody density in uterus-rectum-fossa (23/34, 67.6%). 3. The CT imaging features of tubal pregnancy was classified as: (1) Pregnant sac type (4/34, 11.8%); (2) Cystic (8/34, 23.5%); (3) Massive type (17/34, 50%); (4) Chronic mass type (2/34, 5.9%); (5) Bleeding type (3/34, 8.8%). 4. The CT imaging appearance of tubal pregnancy related with the pregnancy location; 5. The CT imaging appearance of tubal pregnancy related with the clinical significant. Conclusion: The CT imaging appearance of tubal pregnancy has some features, which can help in the diagnosis or differential diagnosis of the pelvis masses. CT scan is an effective supplementary attempt to the clinically and ultrasonographically suspected tubal pregnancy patients.

The purpose of this study was to describe the range of appearances of adrenal phaeochromocytomas on T2-weighted MRI, correlate appearances with histopathology, and quantify the incidence of the previously described hyperintense appearance. The appearance and MR characteristics of 44 phaeochromocytomas were reviewed retrospectively. T2-weighted appearances were grouped: (1) 'classical', homogeneous, high signal intensity, isointense to CSF; (2) homogeneous, isointense or minimally hyperintense to spleen, hypointense to CSF; (3) heterogeneous, marbled appearance; (4) heterogeneous, multiple high signal intensity pockets. All 44 adrenal phaeochromocytomas were well circumscribed, 1.2-15 cm in maximum diameter, with no visual or quantitative signal loss on chemical shift imaging. On T2-weighted MRI 5/44 (11%) had group 1 appearance; 15/44 (34%) group 2, 7/44 (16%) group 3; and 17/44 (39%) group 4. Homogeneous group 1 and 2 lesions were smaller (mean 4.5 cm) than heterogeneous group 3 and 4 lesions (mean 6.3 cm). Increasing MRI heterogeneity correlated pathologically with increasing amounts of haemorrhage, necrosis and fibrosis. No MRI features were predictive of malignancy. Non-functioning phaeochromocytomas were larger than functioning lesions. No size difference was seen between syndrome and sporadic lesions. In this large series we report a wide range of appearances of adrenal phaeochromocytomas on T2-weighted MRI. The previously described classical hyperintense phaeochromocytoma is relatively uncommon.

[From teratology to mythology: ancient legends].

Science.gov (United States)

Stahl, A; Tourame, P

2010-12-01

The mythology of the Greeks and Romans is full of monsters of fiction: giants, cyclops, centaurs, hydras, Gorgons… The accounts of travelers, reproduced in the Natural History of Pline l'Ancien reported the existence, in distant countries, of men with a dog's head (baboons), of men with a single tall foot (sciapode), beings whose face is embedded in the chest (or acephala blemmyes), to which must be added a wide variety of men with no mouth, no nose, or equipped with giant ears or feet turned backwards, as well as hermaphrodites. Teratology reports on monstrous births, which have constituted the factual basis from which the imagination conceived adults whose morphology corresponds to the monsters of legend. Newborns sirenomelia were behind the legend of sciapode and sirens. Cyclopia have inspired the legend of the cyclops. Anencephaly probably explains the description of headless or blemmyes. The genesis of the legend of baboons may have multiple origins: firstly the existence of people suffering from congenital hypertrichosis, on the other hand, the influence of Egyptian mythology where the god Anubis has a dog's head. The acardiac fetus may explain some monstrous forms, features the work of Hieronymus Bosch. The significance of the monsters of legend, their genesis, their persistence through the ages is complex. By approaching teratology, we added a new field of exploration of real monsters of antiquity and Middle Ages. Copyright © 2010. Published by Elsevier SAS.

Changes in Appearance in the Presence of Major Stress Events

Directory of Open Access Journals (Sweden)

Megan E. Stitz

2013-04-01

Full Text Available The relationship between experiencing major stress events (MSEs and changes in appearance (CAs was studied in a sample of 128 participants. All participants completed the Major Stress Event and Changes in Appearance Inventory. Results indicated a significant correlation between experiencing MSEs and considered or actual CAs (r = .50 p < .01. Scores on the Changes in Appearance Inventory were significantly higher in groups with moderate to high scores on the Major Stress Event scale. This relationship between MSEs and CAs was affected by age but not gender. These results suggest that stressful life events may prompt body image dissatisfaction and underlie motivations for changes in body appearance to promote self-image. Successive or dramatic appearance changes may be an important signal of stressful experiences.

same conditions as in lasers. However, the emission that is amplified in this case is not visible light as in lasers, but rather microwave radiation [3]. They are therefore known under the name masers or Microwave Amplified Stimulated Emission Radiators. This radiation is not visible to the human eye or optical astronomical detectors, but must be captured with astronomical radio telescopes. Later, silicon-monoxide (SiO) masers were discovered in which the molecules that amplify the microwave emission are made up of equal proportions of silicon (Si) and oxygen (O). The discovery of the first extra-galactic SiO maser In May 1995, new state-of-the-art receivers were installed on the Swedish-ESO Submillimetre Telescope (SEST) , a radio dish measuring 15 metres across at the ESO La Silla Observatory in Chile. The great technical improvement of the receivers and the excellent quality of this observing site and of the telescope itself make it one of the world's most powerful instruments for this type of research. And indeed, immediately after the installation of the new receivers, the first observations bore fruit. The astronomers decided to look with the telescope at the Large Magellanic Cloud (LMC), a satellite galaxy to the Milky Way galaxy in which we live. On a dark night in the Southern Hemisphere, one can easily spot the LMC with the naked eye as a little `cloud', seen in the direction of the southern constellation of Doradus (The Goldfish). Although much smaller than the Milky Way, it still contains many millions of stars. The astronomers chose to observe the largest known star in the LMC and they registered its microwave radiation for no less than 26 hours. Most of the observing was done during daytime, which is possible with this type of instrument: at microwave wavelengths, the sky appears dark even during the day. The astronomers were delighted to see the star shining at microwave wavelengths, cf. ESO Press Photo 16/96. The measured wavelength leaves no doubt that

The decoherence effect appears at the border between quantum world and macroscopic reality when the superposition of quantum states collapses into one particular state. This article deals with an experiment made to study for the first time the decoherence phenomenon. Circular Rydberg atoms of rubidium and superconducting cavity are the tools used to seize the very moment when the quantum superposition vanishes. This experimental proof of decoherence allows to perceive the limitations of the applications of quantum physics to fields such as quantum computing. This kind of experiment could be used to test other properties of quantum systems. (A.C.)

Sucu, Hasan Kamil; Akar, Ömer

2014-01-01

To investigate the reason for and the course of the double-layer appearance in the postoperative computed tomographies (CTs) of chronic subdural hematoma (CSDHs). We reviewed CSDH cases that were operated on during the last 3 years, between January 2008 and December 2010. We checked the preoperative, early postoperative, and late postoperative CTs of these patients. We investigated the relationship between the formation of a double-layer appearance and the prognoses and demographic characteristics of the patients. Our database included 119 cases. A double-layer appearance was found in the postoperative CTs of 34 cases. The mean age of double-layer cases was older (72.5 ± 12.1) than that of the remaining 85 cases (63.1 ± 17.8). We did not find any relationship between the double-layer appearance and the reoperation/recurrence/death rates. The double-layer appearance after evacuation of a CSDH might be caused by enlargement of the subarachnoid space and is not related to the presence of any residual hematoma. This appearance is not considered as a reason for reoperation.

Congenital malformation of spinal dysraphism followed by hydrocephalus are phenomenon reveals during intrauterine child growth. Prime objective of this work was to present Comparison of hydrocephalus appearance at spinal dysraphism respectively at its meningocele and myelomeningocele forms in Neurosurgery Clinic in UCC in Prishtina. It is perfected with retrospective and prospective method precisely of its epidemiologic part summarizing notices from patients' histories which in 2000-2006 are hospitalized in Neurosurgery Clinic from (QFLPK)--Pediatric Clinic and Children Box (Department)--Gynecology Clinic and from Sanitary Regional Center throughout Kosova. Our study objects were two groups, as the first group 90 patients with spinal dysraphism where neurosurgery operations were done and classified types of dysraphism. At myelomeningocele hydrocephalus has dominated and in a percent of appearance and as acute of its active form was 97% of hydrocephalus form where subjected to cerebrospinal liquid derivation with ventriculo -peritoneal shunt in comparison with meningocele we do not have involvation of spinal nerve element, hydrocephalus takes active form with intervention indication in 60% of cases. Reflection in shown deficit aspect is totally different at myelomeningoceles where lower paraplegia dominate more than paraparesis. The second patient operative technique developed by hydrocephalus with neurosurgical intervention indication has to do with placing of (VP) ventriculo- peritoneal system (shant) at myelomeningoceles with hydrocephalus 58 cases and 12 cases meningoceles with hydrocephalus. Post operative meningitis (shant meningitis): from 70 operated cases of hydrocephalus with spinal dysraphism shunts complications from all types are just cases. Finally that appearance of hydrocephalus compared at spinal dysraphism dominate at myellomeningoceles as in notice time aspect, it is persisting and further acute, with vital motivation for neurosurgical

This review was performed to describe the range of magnetic resonance imaging (MRI) appearances of borderline ovarian tumours. The MRI findings in 26 patients with 31 borderline ovarian tumours (mean age: 40.1 years, range: 14-85 years) were retrospectively reviewed. For each tumour, site, size, MRI characteristics, and enhancement following gadolinium administration were recorded. There were 20 serous and 11 mucinous borderline ovarian subtypes. Nine of 26 patients demonstrated bilateral disease on MRI; synchronous contralateral ovarian disease included three benign, five serous borderline, and one serous invasive tumour. A history of a metachronous mucinous borderline tumour was identified in one patient. MRI appearances were classified into four morphological categories: group 1 (6/31, 19%), unilocular cysts; group 2 (6/31, 19%), minimally septate cysts with papillary projections; group 3 (14/31, 45%), markedly septate lesions with plaque-like excrescences; and group 4 (5/31, 16%), predominantly solid with exophytic papillary projections, all of serous subtype. There was a significant difference in mean volume between serous (841.5 cm{sup 3}) and mucinous (6358.2 cm{sup 3}) subtypes (p = 0.009). All tumours demonstrated at least one MRI feature suggestive of malignancy. The present review demonstrates the variable MRI appearances of borderline ovarian tumours along with imaging features suggestive of tumour subtype. In patients in whom the clinical features are suggestive of a borderline ovarian tumour (young age and normal or minimally elevated CA125), the ability to predict a borderline disease using morphological features observed on MRI would be extremely helpful in surgical planning, with the potential to offer fertility or ovary-preserving surgery. Future studies are required to further this aim.

Possible Tau Appearance Experiment with Atmospheric Neutrinos

Energy Technology Data Exchange (ETDEWEB)

Stanev, Todor

1999-12-27

We suggest an experimental measurement that could detect the appearance of tau neutrinos due to {nu}{sub {mu}}{yields}{nu}{sub {tau}} oscillations of atmospheric neutrinos by measuring the energy spectra of neutrino induced showers. {tau} neutrinos deposit a large fraction of their energy in showers generated by {nu}{sub {tau}} charge current interactions and the subsequent {tau} -lepton decay. The appearance of {nu}{sub {tau}} will enhance the spectrum of neutrino induced showers in energy ranges corresponding to the neutrino oscillation parameters. A shower rate lower than the ''no oscillation'' prediction is an indication for {nu}{sub {mu}}{yields}{nu}{sub s} oscillations. (c) 1999 The American Physical Society.

Aim: To evaluate the 3 T MR cholangiopancreatography (MRCP) appearances of biliary ascariasis. Materials and methods: Nine patients with a MRCP diagnosis of biliary ascariasis were reviewed. All patients had endoscopic retrograde cholangiopancreatography (ERCP) or surgical confirmation of the disease. Results: On thin-slab MRCP imaging, Ascaris worms are clearly demarcated within the biliary tree. All the identified worms demonstrated a characteristic three-parallel-lines appearance. The middle high-signal intensity line is sandwiched between two low-signal intensity lines and they are in turn surrounded by high signal bile. On thick-slab MRCP the worms also show the three-line sign but with less clarity. However, thick-slab MRCP has the advantage of providing three-dimensional ERCP-like images of the pancreaticobiliary system. Conclusion: The 'three-line' sign appears to be a characteristic sign of biliary ascariasis on 3 T MRCP.

Background: The jaw (an unusual site of primary tumors in children and adolescents) has lesions often found incidentally by dentists on routine panoramic radiographs or during examination of a child who has swelling or tooth pain. Objective: This pictorial seeks to familiarize pediatric radiologists with the radiographic appearance of a variety of primary jaw lesions. Materials and methods: We retrospectively searched institutional records for cases of primary jaw lesions in children and adolescents. Jaw lesions were characterized as: I, well-circumscribed radiolucent lesions; II, lesions with mixed or variable appearance; III, poorly circumscribed radiolucent lesions; and IV, radiopaque lesions. Results: Although most oral and maxillofacial lesions in children are benign, a broad spectrum of tumors was identified; lesions may occur in patients with unrelated prior malignancy. Conclusion: Because radiologic studies may identify jaw lesions and direct further care, familiarity with the appearance of these entities is prudent. (orig.)

"Hey, check it out, there's actually fans": (Disempowerment and (misrepresentation of cult fandom in "Supernatural"

Directory of Open Access Journals (Sweden)

Laura E. Felschow

2010-03-01

Full Text Available As Supernatural enters season 5, its status as a cult hit is becoming more evident both in the press and within the text of the series itself. The open acknowledgment of the show's fandom within 4.18 "The Monster at the End of This Book" has altered the power relationship between the product and its fans and brought on controversy regarding the creative team's attitude toward fandom in general. To investigate this relationship between Supernatural and its devoted fans, I will first develop a working definition of the cult fan and illustrate the many ways in which Supernatural is an ideal cult text, despite not having been marketed by its producers and network as such. Having set forth this framework, I will outline the dynamic that existed between Supernatural and its cult fans prior to "The Monster at the End of This Book." I will then demonstrate how "The Monster at the End of This Book" simultaneously empowers and disempowers Supernatural's cult fans by representing them within the show's diegesis and what the consequences of these (misrepresentations might be.

Saliency Changes Appearance

2011-01-01

Numerous studies have suggested that the deployment of attention is linked to saliency. In contrast, very little is known about how salient objects are perceived. To probe the perception of salient elements, observers compared two horizontally aligned stimuli in an array of eight elements. One of them was salient because of its orientation or direction of motion. We observed that the perceived luminance contrast or color saturation of the salient element increased: the salient stimulus looked even more salient. We explored the possibility that changes in appearance were caused by attention. We chose an event-related potential indexing attentional selection, the N2pc, to answer this question. The absence of an N2pc to the salient object provides preliminary evidence against involuntary attentional capture by the salient element. We suggest that signals from a master saliency map flow back into individual feature maps. These signals boost the perceived feature contrast of salient objects, even on perceptual dimensions different from the one that initially defined saliency. PMID:22162760

Primary oat cell carcinoma of the esophagus is a very rare tumour. The radiographic appearance of the three cases described in this paper are unusual because they resemble benign lesions such as leiomyoma, fibrous polyp and candidiasis. It would be interesting to investigate whether such an unusual appearance is common for this neoplasm.

Full Text Available Background/Aim. Dental appearance plays an important role in practically all personal social interactions. The main factors that define the dental appearance are tooth colour, shape and position, quality of restoration, and the general position of the teeth in arch, especially in the anterior region. The aim of this study was to evaluate the impact of dental status (tooth shape, fracture, dental and prosthetic restorations and presence of plaque on patient''s satisfaction with the dental appearance, controlling for the age and gender. Methods. A total of 700 Caucasian subjects (439 women aged 18–86 (median 45 years participated in the cross-sectional study. Study included clinical examination and self-administrated questionnaire based on selfperceived aesthetics and satisfaction with the appearance of their maxillary anterior teeth. Results. A regression analysis demonstrated that presence of dental plaque, tooth fracture, composite fillings and crowns had significant independent contribution and were negative predictors of satisfaction with teeth appearance. Participants with presence of plaque on upper teeth (p < 0.001, fractures (p = 0.005, composite fillings (p < 0.001 and crowns (p = 0.032 were less satisfied than those without it. Model explains 12% or variance of general satisfaction with the appearance of maxillary frontal teeth (p < 0.001 and the major contributors are composite fillings (5.3% and plaque (3.2%. Tooth shape, age and gender were not significant predictors of satisfaction. Conclusion. Satisfaction with the teeth appearance is under the influence of many factors with significant negative influence of presence of dental plaque, fractures, composite restorations, and crowns.

Gaucher's disease is an inborn error of metabolism in which glucocerebroside accumlates within reticuloendotherial cells of spleen, liver and bone marrow. The scintigraphic appearances are described in a 19-year-old man with Gaucher's disease. The colloid scan showed increased uptake in the lung and bone marrow of legs where the reticuloendotherial system was activated. The bone scan demonstrated increased activity in the metaphyseal and diaphyseal region infiltrated by Gaucher's cell. Ga-67 was thought to be accumlated in the progressive focus of the disease.

Perspectives of fetal dystocia in cattle and buffalo

Directory of Open Access Journals (Sweden)

Govind Narayan Purohit

2012-04-01

Full Text Available We review the causes of fetal dystocia in cows and buffalo. Two fetal causes are distinct fetal oversize and fetal abnormalities. Fetal oversize is common in heifers, cows of beef cattle breeds, prolonged gestations, increased calf birth weight, male calves and perinatal fetal death with resultant emphysema. Fetal abnormalities include monsters, fetal diseases and fetal maldispositions, and it is difficult to deliver such fetuses because of their altered shape. Although monsters are rare in cattle, a large number of monstrosities have been reported in river buffalo; yet also here, overall incidence is low. Diseases of the fetus resulting in dystocia include hydrocephalus, ascites, anasarca and hydrothorax. The most common cause of dystocia in cattle seems to be fetal maldispositions, of which limb flexion and head deviation appear to be the most frequent. We provide a brief description of the management of dystocia from different causes in cattle and buffalo. A case analysis of 192 and 112 dystocia in cattle and buffalo, respectively, at our referral center revealed that dystocia is significantly higher (P<0.05 in first and second parity cows and buffalo, and that dystocia of fetal origin is common in cows (65.62% but less frequent (40.17% in buffalo. In buffalo, the single biggest cause of dystocia was uterine torsion (53.57%. Fetal survival was significantly (P<0.05 higher both in cows and buffalo when delivery was completed within 12 h of second stage of labor.

Ideological Fission

; it is a materialisation of an ideological fission which attempts to excise certain ideological constructions, yet paradoxically casting them in a form that is recognizable and familiar. The monstrous metonomy which is used shows us glimpses of a horrid being, intended to vilify the attack on New York City. However......, it is a being which is reminiscent of earlier monsters - from Godzilla to The Blob. It is evident that the Cloverfield monster is a paradoxical construction which attempts to articulate fear and loathing about terrorism, but ends up trapped in an ideological dead-end maze, unable to do anything other than...

The infant spine has a different MR appearance than the adult spine. The authors used MR and cryomicrotomy to study the spines of stillborn fetuses and infants during in the perinatal period. In the fetal spine, Sharpey fibers are incompletely developed, the nucleus and anulus are more distinctly differentiated, the nucleus contains a transverse structure not seen in the adult, notochordal cells are more prominent, and the vertebral bodies and neural arches are incompletely ossified. The spinal landmarks and their MR appearances will be illustrated. Variations, such as calcification of the nucleus pulposus, are illustrated

Objective: To evaluate the imaging appearances of abdominally retained crumpled gauze with US, CT and MRI and the changes with time. Methods: Eight rabbits were operated and crumpled gauze was put into in their abdominal cavity. US , plain and enhanced CT and MRI scan were performed on the day of operation, and 1 to 7 weeks after operation. The imaging appearances were compared with operation findings. Pathologic examination was done simultaneously. Results: Abdominally retained crumpled gauze was instantly adhesive with omentum and neighboring intestines tightly. Fibro-connective tissue membrane was produced at the adhesion site gradually, spreading out to enclose the crumpled gauze. The enclosure was finished completely in 3 to 4 weeks. Thickened membrane also invaded into the spaces within the gauze. The crumpled gauze was eventually infected. These changes could be revealed on US, CT or MRI scans. The US appearance exhibited a hyper echoic arc zone with broad clean acoustic shadow behind. It appeared as a soft tissue mass to CT and MRI scans. In early stage CT scan could easily show the gas within the crumpled gauze. CT and MRI enhanced scans showed only the enhanced membrane and no enhancement of the crumpled gauze. Conclusion: US, CT and MRI have quite characteristic appearances of the abdominally retained crumpled gauze, especially when combined imaging techniques were employed, which can lead to a correct diagnosis together with a history of operation

This study examined relationships between physical appearance concerns (fear of fat, body image disturbance; BIDQ), disgust, and anti-fat prejudice (dislike, blame), and tested whether disgust mediates relationships between physical appearance concerns and anti-fat prejudice. Participants (N=1649; age=28 years) provided demographic data and completed measures of anti-fat prejudice, tendency to feel disgust, and physical appearance concerns. Univariate, multivariate, and mediation analyses were conducted. Univariate and multivariate associations were found between fear of fat, BIDQ, disgust, and anti-fat prejudice for women. For women only, mediation analyses showed that disgust partially mediated relationships between physical appearance concerns and dislike of fat people. For men, univariate and multivariate relationships were found between fear of fat, and dislike and blame of fat people, but disgust was not related to anti-fat prejudice. Newer constructs centering on physical appearance concerns and disgust appear promising candidates for understanding anti-fat prejudice. Copyright © 2013 Elsevier Ltd. All rights reserved.

72-directional display having VGA resolution for high-appearance image generation

Science.gov (United States)

Takaki, Yasuhiro; Dairiki, Takeshi

2006-02-01

The high-density directional display, which was originally developed in order to realize a natural 3D display, is not only a 3D display but also a high-appearance display. The appearances of objects, such as glare and transparency, are the results of the reflection and the refraction of rays. The faithful reproduction of such appearances of objects is impossible using conventional 2D displays because rays diffuse on the display screen. The high-density directional display precisely controls the horizontal ray directions so that it can reproduce the appearances of objects. The fidelity of the reproduction of object appearances depends on the ray angle sampling pitch. The angle sampling pitch is determined by considering the human eye imaging system. In the present study the high-appearance display which has the resolution of 640×400 and emits rays in 72 different horizontal directions with the angle pitch of 0.38° was constructed. Two 72-directional displays were combined, each of which consisted of a high-resolution LCD panel (3,840×2,400) and a slanted lenticular sheet. Two images produced by two displays were superimposed by a half mirror. A slit array was placed at the focal plane of the lenticular sheet for each display to reduce the horizontal image crosstalk in the combined image. The impression analysis shows that the high-appearance display provides higher appearances and presence than the conventional 2D displays do.

Stereotactic thalamotomy is a useful method of treatment in selected cases of Parkinsonism. Previously, the consequences of these stereotactic lesions have been assessed by means of their postoperative clinical effects and CT appearances. Now, however, MR imaging allows a clearer, three-dimensional demonstration of the lesion than does CT scanning; its appearance can now be correlated with the results obtained by the use of the radiofrequency method and its clinical effects. The authors have performed postoperative MR imaging on 12 patients with a total of 13 thalamotomies. The early postoperative MR appearance of these lesions is composed of two relatively clear and distinct parts. In T{sub 1}-weighted imaging, there is a central hyper-intense core and a low-intensity area surrounding it. In T{sub 2}-weighted imaging, there is a central hypo-intense core and a high-intensity area surrounding it. The late postoperative MR appearance is a low-intensity spot in T{sub 1}-weighted imaging and a high-intensity spot in T{sub 2}-weighted imaging. MR imaging is very useful for the postoperative evaluation of stereotactic thalamotomy in helping to identify the location of and the chronological change in the radiofrequency lesions. (author).

Cross sectional. This study presents the factor analysis of the Spinal Appearance Questionnaire (SAQ) and its psychometric properties. Although the SAQ has been administered to a large sample of patients with adolescent idiopathic scoliosis (AIS) treated surgically, its psychometric properties have not been fully evaluated. This study presents the factor analysis and scoring of the SAQ and evaluates its psychometric properties. The SAQ and the Scoliosis Research Society-22 (SRS-22) were administered to AIS patients who were being observed, braced or scheduled for surgery. Standard demographic data and radiographic measures including Lenke type and curve magnitude were also collected. Of the 1802 patients, 83% were female; with a mean age of 14.8 years and mean initial Cobb angle of 55.8° (range, 0°-123°). From the 32 items of the SAQ, 15 loaded on two factors with consistent and significant correlations across all Lenke types. There is an Appearance (items 1-10) and an Expectations factor (items 12-15). Responses are summed giving a range of 5 to 50 for the Appearance domain and 5 to 20 for the Expectations domain. The Cronbach's α was 0.88 for both domains and Total score with a test-retest reliability of 0.81 for Appearance and 0.91 for Expectations. Correlations with major curve magnitude were higher for the SAQ Appearance and SAQ Total scores compared to correlations between the SRS Appearance and SRS Total scores. The SAQ and SRS-22 Scores were statistically significantly different in patients who were scheduled for surgery compared to those who were observed or braced. The SAQ is a valid measure of self-image in patients with AIS with greater correlation to curve magnitude than SRS Appearance and Total score. It also discriminates between patients who require surgery from those who do not.

Smida, M.; Jalel, C.; Mrad, K.; Sayed, M.; Ben Abdallah, O.; Ben Chehida, F.; Ben Ghachem, M.

2001-01-01

The authors report 2 cases of 2 children aging 11 and 12-years-old presenting hydatidosis in the upper extremity of 2 long bones femur and tibia. In 2 cases, radiological appearances were atypical. In the femur, plain radiographs revealed multiple lucencies, irregular, located in the superior extremity with a periosteal reaction. The CT scan confirmed these data and showed a cortical rupture, extension to soft tissue with contrast enhancement. In the tibia, plain radiographies showed delimited lucencies, confluent with a rim condensation in the proximal epiphyseal-metaphyseal area. Echography and CT are helpful when radiological appearances are unusual. (authors)

Postmortem radiology is a rapidly developing specialty that is increasingly used as an adjunct to or substitute for conventional autopsy. The goal is to find patterns of disease and possibly the cause of death. Postmortem CT images bring to light processes of decomposition most radiologists are unfamiliar with. These postmortem changes, such as the formation of gas and edema, should not be mistaken for pathological processes that occur in living persons. In this review we discuss the normal postmortem thoraco-abdominal changes and how these appear on CT images, as well as how to differentiate these findings from those of pathological processes.

Appearance-based rejection sensitivity: implications for mental and physical health, affect, and motivation.

Science.gov (United States)

Park, Lora E

2007-04-01

Appearance-Based Rejection Sensitivity (Appearance-RS) is a personality-processing system characterized by anxious concerns and expectations about being rejected based on one's physical attractiveness. People differ in their sensitivity to rejection based on appearance, with consequences for mental and physical health, self-esteem, affect, and feelings of belonging. Study 1 describes the development and validation of the Appearance-RS scale, its relation to personality variables and to health-related outcomes. Study 2 provides experimental evidence that high Appearance-RS people feel more alone and rejected when asked to think about negative aspects of their appearance. Finally, Study 3 tests ways to reduce the negative effects of receiving an appearance threat among high Appearance-RS participants. Specifically, high Appearance-RS participants who engaged in self-affirmation (thought of their personal strengths) or received a secure attachment prime (thought of a close, caring relationship) were buffered from the negative effects of an appearance threat on subsequent state self-esteem and mood.

Consensus Coding as a Tool in Visual Appearance Research

Directory of Open Access Journals (Sweden)

D R Simmons

2011-04-01

Full Text Available A common problem in visual appearance research is how to quantitatively characterise the visual appearance of a region of an image which is categorised by human observers in the same way. An example of this is scarring in medical images (Ayoub et al, 2010, The Cleft-Palate Craniofacial Journal, in press. We have argued that “scarriness” is itself a visual appearance descriptor which summarises the distinctive combination of colour, texture and shape information which allows us to distinguish scarred from non-scarred tissue (Simmons et al, ECVP 2009. Other potential descriptors for other image classes would be “metallic”, “natural”, or “liquid”. Having developed an automatic algorithm to locate scars in medical images, we then tested “ground truth” by asking untrained observers to draw around the region of scarring. The shape and size of the scar on the image was defined by building a contour plot of the agreement between observers' outlines and thresholding at the point above which 50% of the observers agreed: a consensus coding scheme. Based on the variability in the amount of overlap between the scar as defined by the algorithm, and the consensus scar of the observers, we have concluded that the algorithm does not completely capture the putative appearance descriptor “scarriness”. A simultaneous analysis of qualitative descriptions of the scarring by the observers revealed that other image features than those encoded by the algorithm (colour and texture might be important, such as scar boundary shape. This approach to visual appearance research in medical imaging has potential applications in other application areas, such as botany, geology and archaeology.

This study evaluated the prevalence and effects of teasing by family members on body dissatisfaction, eating disturbance, and psychological functioning. Self-report data were collected from 372 middle school girls who were part of a larger study in a Tampa Bay, Florida area middle school (mean age: 12.6 years; 85% Caucasian). Twenty-three percent of participants reported appearance-related teasing by a parent, and 12% were teased by a parent about being heavy. Nineteen percent of the girls reported appearance-related teasing by fathers, 13% reported appearance-related teasing by mothers, and 29% reported appearance-related teasing by siblings. After controlling for body mass index (BMI) and maternal teasing, paternal teasing was a significant predictor of body dissatisfaction, comparison, thin-ideal internalization, restriction, bulimic behaviors, self-esteem, and depression. After controlling for BMI and paternal teasing, maternal teasing was a significant predictor of depression. After controlling for BMI and maternal teasing, paternal teasing significantly increased the odds of having a sibling who teases. Girls who reported being teased by at least one sibling demonstrated significantly higher levels of body dissatisfaction, comparison, thin-ideal internalization, restriction, bulimic behaviors, depression, and significantly lower levels of self-esteem than those girls who reported they were not teased by their siblings. Frequency of teasing was associated with higher levels of negative outcomes. This study has implications for treatment and prevention of eating disorders. The results suggest that health care providers should assess appearance-related teasing in their patients' lives to identify girls who may be at risk for body image and eating disturbance and poor psychological functioning.

"Appearance potent"? A content analysis of UK gay and straight men's magazines.

Science.gov (United States)

Jankowski, Glen S; Fawkner, Helen; Slater, Amy; Tiggemann, Marika

2014-09-01

With little actual appraisal, a more 'appearance potent' (i.e., a reverence for appearance ideals) subculture has been used to explain gay men's greater body dissatisfaction in comparison to straight men's. This study sought to assess the respective appearance potency of each subculture by a content analysis of 32 issues of the most read gay (Attitude, Gay Times) and straight men's magazines (Men's Health, FHM) in the UK. Images of men and women were coded for their physical characteristics, objectification and nudity, as were the number of appearance adverts and articles. The gay men's magazines featured more images of men that were appearance ideal, nude and sexualized than the straight men's magazines. The converse was true for the images of women and appearance adverts. Although more research is needed to understand the effect of this content on the viewer, the findings are consistent with a more appearance potent gay male subculture. Crown Copyright © 2014.

Kvalem, Ingela Lundin; von Soest, Tilmann; Roald, Helge E; Skolleborg, Knut Chr

2006-09-01

This study investigates how personality traits in combination with frequency of and emotional reaction to negative comments about appearance while growing up are related to appearance evaluation and orientation among adult women. Nine hundred and seven participants from a representative sample of Norwegian women aged 22-55, answered questions measuring body image, personality (Big Five), and history of experiencing negative comments about appearance. Results indicated that only emotional reaction to negative comments about appearance significantly predicted both appearance evaluation and orientation, while frequency of negative comments did not. Being extrovert predicted more positive appearance evaluation and being more appearance oriented than being introvert. Scoring high on neuroticism was related to negative appearance evaluation and high appearance orientation. The findings demonstrate the importance of differentiating between the frequency and the emotional impact of teasing as well as including personality traits when studying body image.

Synthetic ossicular replacements: Normal and abnormal CT appearance

International Nuclear Information System (INIS)

Swartz, J.D.; Zwillenberg, S.; Berger, A.S.; Granoff, D.W.; Popky, G.L.

1986-01-01

Numerous synthetic ossicular replacements are currently in use. The TORP conducts sound from the newly formed tympanic membrane to the oval window; the PORP is used when the stapes superstructure is maintained, being interposed between the tympanic membrane and the stapes capitulum. In 12 patients the surgical results of ossicular replacement procedures were good, which gave the author the opportunity to study the normal CT appearance. In an additional 10 patients CT was performed before surgical revision. Using CT, they have been able to diagnose subluxation and fibrous tissue fixation. In two patients the CT appearance was unremarkable, but at surgery lateralization of the graft was found, with a nonfunctioning interface

Appearance of Keplerian discs orbiting Kerr superspinars

We study optical phenomena related to the appearance of Keplerian accretion discs orbiting Kerr superspinars predicted by string theory. The superspinar exterior is described by standard Kerr naked singularity geometry breaking the black hole limit on the internal angular momentum (spin). We construct local photon escape cones for a variety of orbiting sources that enable us to determine the superspinars silhouette in the case of distant observers. We show that the superspinar silhouette depends strongly on the assumed edge where the external Kerr spacetime is joined to the internal spacetime governed by string theory and significantly differs from the black hole silhouette. The appearance of the accretion disc is strongly dependent on the value of the superspinar spin in both their shape and frequency shift profile. Apparent extension of the disc grows significantly with the growing spin, while the frequency shift grows with the descending spin. This behaviour differs substantially from the appearance of discs orbiting black holes enabling thus, at least in principle, to distinguish clearly the Kerr superspinars and black holes. In vicinity of a Kerr superspinar the non-escaped photons have to be separated to those captured by the superspinar and those being trapped in its strong gravitational field leading to self-illumination of the disc that could even influence its structure and cause self-reflection effect of radiation of the disc. The amount of trapped photons grows with descending superspinar spin. We thus can expect significant self-illumination effects in the field of Kerr superspinars with near-extreme spin a {approx} 1.

Full Text Available Hercules killed the Hydra of Lerna in a bloody battle—the second of the labor tasks imposed upon him in atonement for his hideous crimes. The Hydra was a horrible, aggressive mythological monster with many heads and poisonous blood, whose heads multiplied each time one of them was severed. This article explores some mathematical methods about this interesting epic battle. A generalization of the original Kirby & Paris model is proposed. We also study the connection of this model with Goodstein ultra-growing and recursive sequences. As an interesting application, we next analyze the inevitable death of another huge monster of our modern era: the Internet.

The purpose of this article is to review and illustrate the spectrum of computed tomography (CT) appearances of abdominal tuberculosis. Tuberculosis can affect any organ or tissue in the abdomen, and can be mistaken for other inflammatory or neoplastic conditions. The most common sites of tuberculosis in the abdomen include lymph nodes, genitourinary tract, peritoneal cavity and gastrointestinal tract. The liver, spleen, biliary tract, pancreas and adrenals are rarely affected, but are more likely in HIV-seropositive patients and in miliary tuberculosis. This article should alert the radiologist to consider abdominal tuberculosis in the correct clinical setting to ensure timely diagnosis and enable appropriate treatment.

Full Text Available Non Steroidal Anti Inflammatory Drugs (NSAID have been associated with a sudden and sustained rise in the incidence of gastrointestinal ulcer complications. The aim of the study was to reveal the endoscopical abnormalities found in the duodenum & proximal jejunum due to NSAID. Thirty eight patients taking NSAID for their arthritis or rheumatism were included in this study. Gastro-duodeno-jejunoscopy was done with Olympus PCF-10. The endoscopical appearances of NSAID entero gastropathy were evaluated with a scoring system. The NSAID-entero-gastropathy appearances were endoscopically seen as hyperemia, erosion and ulcer. From all patient recruited, 7.9% complaint of diarrhea and 71.1% complaint of dyspepsia. Endoscopically, in the duodenal bulb we found 79% cases of hyperemia, 39.5% cases of erosion and 7.9% cases of ulcer. In the second part (descending part of the duodenum we found 28.9% cases of hyperemia, 15.8% cases of erosion and 2.6% case of ulcer. In the jejunum, we found 7.9% cases of hyperemia, 2.6% case of erosion and no ulcer. It is concluded that the most frequent abnormal endoscopical appearances in NSAID- enteropathy was hyperemia. The most frequent site of NSAID-enteropathy abnormal findings was in the duodenal bulb. (Med J Indones 2005; 14: 225-9Keywords: NSAID-enteropathy, endoscopical appearances.

This study explored appearance-related images and messages present in pregnancy magazines (e.g. Fit Pregnancy, Pregnancy & Newborn, and Pregnancy Magazine). A substantial portion of advertisements and articles promoted appearance-related products or products for postpartum weight loss. Health messages and messages related to diet and exercise were also present. Images also sexualized pregnant women's bodies. Appearance-related messages aimed toward pregnant women may be problematic and may contribute to body dissatisfaction in these women.

1988-05-01

Postoperative CT appearances in 65 cases of chronic subdural hematomas were evaluated in terms of patient's age, preoperative neurological symptoms and CT findings, final outcomes, and so on. All of the cases were treated with trepanation and irrigation. CT appearances were divided into four different types as follows; Type Ia: No abnormal findings in the subdural sapce, Type Ib: The same as above except for a linear high density suggestive of thickened outer membrane, Type II: Persistence subdural fluid collection and widened cortical sulci which indicate underlining brain atrophy, Type III: Remaining hematoma and/or density changes during follow-up period. Although the mean age of the patients in type Ib was higher than those in type Ia and reexpansion of the brain appear to delay in type Ib and preoperative CT in type Ib tended to show mixed density, final outcome in both groups were excellent. Characteristics in type II were that most of cases were in the eighth decade, preceding head injury was unclear, preoperative psychiatric symptoms and disturbance of consciousness were common and postoperative improvement of the symptoms was not satisfactory compared to other types. Aged patients as in type Ib and type II and thick hematomas of over 2 cm depth with mixed or high density tended to show type III postoperatively. All of the nine patients who required reoperation were included in this type. The present study indicates that thick hematomas with sizable mass effect and mixed or high density in the aged must be carefully treated, such as with placement of the subdural drainage or keeping the patient in the Trendelenburg position, to facilitate postoperative reexpansion of the brain.

The aim of this qualitative study was to examine young female sport participants' experiences and thoughts in terms of sport, their bodies, and social appearance norms. Six focus groups with female sport participants (N=25) from Sweden were conducted. Participants raised many positive experiences in relation to their sport participation, but they also witnessed a conflict in the intersection between the culture within their sport (emphasizing physical performance) and the culture outside their sport (emphasizing physical appearance). Through thematic analysis, four themes illustrating the balancing act between these two cultures were formed: (a) the performing body versus the objectified body, (b) food as fuel versus source of shame, (c) appreciation of body type diversity versus appearance prejudice, and (d) empowerment and agency versus disempowerment and restraints. The findings of this study indicate that young women who engage in sport have to face complex, ambiguous, and restricting norms and notions. Copyright © 2017 Elsevier Ltd. All rights reserved.

Experimental and histological studies on appearance mechanism of ring enhancement

1980-01-01

Intracerebral hematoma was experimentally induced in 26 adult dogs of mixed breed by injecting autologous venous blood into the internal capsule of dogs. CT images and histological findings of these dogs with intracerebral hematoma were compared with time, and causes of changes in contrast enhancement (CE) CT images and CE positive images were discussed pathologically. It was thought that CE-CT positive images of intracerebral hematoma did not show special phenomena which occurred variously according to causes of hematoma, but general phenomena observed in the process of recovery of general intracerebral hematoma. Ring enhancement appeared mostly about 9 days after hematoma formation. There was a close relationship between appearance of ring enhancement and new vascularization which appeared in the process of recovery of hematoma. It was also thought that blood-brain barrier (B.B.B.) such as normal cerebral capillary vessels did not exist because new vascularization had the fine structure similar to muscle type capillary vessels. Ring enhancement might be seen probably because of the accumulation of contrast medium in regions where new vascularization without B.B.B. appeared. (Tsunoda, M.)

2012-07-01

We present a methodology to calculate the color appearance of advertising billboards set in indoor and outdoor environments, printed on different types of paper support and viewed under different illuminations. The aim is to simulate the visual appearance of an image printed on a specific support, observed in a certain context and illuminated with a specific source of light. Knowing in advance the visual rendering of an image in different conditions can avoid problems related to its visualization. The proposed method applies a sequence of transformations to convert a four channels image (CMYK) into a spectral one, considering the paper support, then it simulates the chosen illumination, and finally computes an estimation of the appearance.

Hyper-functioning thyroid nodules may produce various scintigraphic appearances on thyroid scans. Autonomously hyper functioning thyroid nodules invariably demonstrate degenerative changes. These changes may give rise to central or less commonly peripheral photopenic areas on a thyroid scan within otherwise a hot nodule. In this report we present a case of hyper functioning autonomous nodule with peripheral degeneration and residual central functioning tissue giving the appearance of an owl's eye. Although rare, this pattern can be seen in a variety of benign and malignant thyroid conditions. (author)

Mammary duct ectasia (MDE), also called periductal mastitis, mammary dysplasia, or plasma cell mastitis, is a benign condition of the mammary gland first described by Haagensen in 1951. The etiology of MDE is unknown and its pathogenesis still controversial; the periductal inflammation could be either the cause or the result of dilated damaged ducts. The process is usually bilateral and asymptomatic, with only a small percentage of patients presenting with symptoms that may include long course of tumour formation, usually subareolar breast lumps, nipple discharge, nipple retraction, mastalgia, and mammary abscess or fistulas. Mammographic presentation of MDE is well known; its features include periductal calcification, benign intraductal calcification, and retroareolar duct dilatation. The periductal calcification results from dystrophic calcification and forms calcified rings or very dense, oval, elongated calcifications, each with a central lucency representing the dilated duct. Intraductal calcifications of duct ectasia represent inspissated intraductal material and are typically of uniform high density, often needle-like, and occasionally branching. Occasionally, there are no mammographic findings, and the diagnosis must rely on sonographic features. Appearance of MDE on ultrasonography (US) depends on the stage of the disease and the contents of the dilated ducts. The acute presentation has been demonstrated in the literature more often than has its chronic counterpart. In the former, duct content can vary from anechoic to isoechoic with surrounding fatty tissue. In chronic MDE, episodes of inflammation are longer. This tends to result in secretions that have a more solid, cheesy texture, partly due to cholesterol crystals, foam cells, and inflammatory cells. For both types of MDE, the appearance can mimic high-grade ductal carcinoma in situ (DCIS) on US. In this essay, 2 chronic MDE cases are presented and their US appearance discussed.

Liposarcoma is a relatively common soft tissue malignancy with a wide spectrum of clinical presentations and imaging appearances. Several subtypes are described, ranging from lesions nearly entirely composed of mature adipose tissue, to tumors with very sparse adipose elements. The imaging appearance of these fatty masses is frequently sufficiently characteristic to allow a specific diagnosis, while in other cases, although a specific diagnosis is not achievable, a meaningful limited differential diagnosis can be established. The purpose of this paper is to review the spectrum of malignant fatty tumors, highlighting the current classification system, clinical presentation and behavior, treatment and spectrum of imaging appearances. The imaging review will emphasize CT scanning and MR imaging, and will stress differentiating radiologic features. (orig.)

Lipoma is the most common soft-tissue tumor, with a wide spectrum of clinical presentations and imaging appearances. Several subtypes are described, ranging from lesions entirely composed of mature adipose tissue to tumors intimately associated with nonadipose tissue, to those composed of brown fat. The imaging appearance of these fatty masses is frequently sufficiently characteristic to allow a specific diagnosis. However, in other cases, although a specific diagnosis is not achievable, a meaningful limited differential diagnosis can be established. The purpose of this manuscript is to review the spectrum of benign fatty tumors highlighting the current classification system, clinical presentation and behavior, spectrum of imaging appearances, and treatment. The imaging review emphasizes computed tomography (CT) scanning and magnetic resonance (MR) imaging, differentiating radiologic features. (orig.)

The aims of this study were to identify (1) the normal range of the appendix on computed tomography (CT), (2) the correlation of patient age and sex with the visibility and appearance of the appendix on CT, and (3) the normal variations in wall thickness, intraluminal content, and location of the appendix. Three hundred seventy-two outpatients underwent abdominopelvic CT. The scans were reviewed on the picture archiving and communication system and appendiceal outer-to-outer wall diameter, wall thickness, location, content and its correlation with appendix diameter were analyzed. The appendix was visualized in 305/372 patients. Its location relative to the cecum was highly variable. The diameter range was 3-10 mm; in 42% of cases the diameter was greater than 6 mm. When the intraluminal content (185/305) was visualized, the diameter was slightly superior to the mean (p=0.0156). In 329 CT scans in which oral contrast material was given, the appendix was filled by contrast material in 74/329 patients. The appendix wall thickness was measurable in 22/305 patients (average 0.15 cm). There is significant overlap between the normal and abnormal CT appearance of the appendix. Consequently the diagnosis of acute appendicitis should be based not only on the appearance of the appendix but also on the presence of secondary signs. (orig.)

Morphological appearance manifolds for group-wise morphometric analysis.

Science.gov (United States)

Lian, Nai-Xiang; Davatzikos, Christos

2011-12-01

Computational anatomy quantifies anatomical shape based on diffeomorphic transformations of a template. However, different templates warping algorithms, regularization parameters, or templates, lead to different representations of the same exact anatomy, raising a uniqueness issue: variations of these parameters are confounding factors as they give rise to non-unique representations. Recently, it has been shown that learning the equivalence class derived from the multitude of representations of a given anatomy can lead to improved and more stable morphological descriptors. Herein, we follow that approach, by approximating this equivalence class of morphological descriptors by a (nonlinear) morphological appearance manifold fitting to the data via a locally linear model. Our approach parallels work in the computer vision field, in which variations lighting, pose and other parameters lead to image appearance manifolds representing the exact same figure in different ways. The proposed framework is then used for group-wise registration and statistical analysis of biomedical images, by employing a minimum variance criterion to perform manifold-constrained optimization, i.e. to traverse each individual's morphological appearance manifold until group variance is minimal. The hypothesis is that this process is likely to reduce aforementioned confounding effects and potentially lead to morphological representations reflecting purely biological variations, instead of variations introduced by modeling assumptions and parameter settings.

'Unusual' MRI appearance of sphenoid sinus mucocele

International Nuclear Information System (INIS)

Ruelle, A.; Pisani, R.; Andrioli, G.

1991-01-01

The authors report a case of sphenoid sinus mucocele which exhibited unusual MRI features. However a review of the literature shows that these lesions may present with different MRI appearances probably related to the variability of the cyst content. Further series are needed for a better definition of the MRI behaviour of the lesions. (orig.)

A recently published study on the development of the turtle shell highlights the important role that development plays in the origin of evolutionary novelties. The evolution of the highly derived adult anatomy of turtles is a prime example of a macroevolutionary event triggered by changes in early embryonic development. Early ontogenetic deviation may cause patterns of morphological change that are not compatible with scenarios of gradualistic, stepwise transformation. Copyright 2001 John Wiley & Sons, Inc.

The appearance of a cigarette brand in a cinema film gives the brand a certain distinction through its association with the characters and general tone of the film. Through the worldwide distribution of films, brands are promoted globally. We assessed the tobacco-brand appearances in a 10-year sample of contemporary films. We viewed the contents of the top 25 US box-office films for each year of release, from 1988 to 1997 (250 films in total). We compared the prevalence of brand appearances for films produced before a voluntary ban on paid product placement by the tobacco industry (1988-90) with films produced after the ban (1991-97). Tobacco-brand appearance was defined as the screen appearance of a brand name, logo, or identifiable trademark on products or product packaging, billboards, store-front advertising, or tobacco promotional items. We defined actor endorsement of a brand as the display of a brand while being handled or used by an actor. More than 85% of the films contained tobacco use. Tobacco brands appeared in 70 (28%) films. Brand appearances were as common in films suitable for adolescent audiences as they were in films for adult audiences (32 vs 35%), and were also present in 20% of those rated for children. Prevalence of brand appearance did not change overall in relation to the ban. However, there was a striking increase in the type of brand appearance depicted, with actor endorsement increasing from 1% of films before the ban to 11% after. Four US cigarette brands accounted for 80% of brand appearances. Revenues outside the USA accounted for 49% of total revenues for these films, indicating a large international audience. Tobacco-brand appearances are common in films and are becoming increasingly endorsed by actors. The most highly advertised US cigarette brands account for most brand appearances, which suggests an advertising motive to this practice.

The spectral appearance of solar-type collapsing protostellar clouds

Bertout, C.; Yorke, H.W.

1978-04-01

In this paper, we review the spectral properties of collapsing protostellar clouds, based on radiative transfer computations in hydrodynamic protostar models. In the first section, the basic results of protostar evolution computations in spherically symmetric and axially symmetry geometries, as they pertain to the appearance of protostars, are briefly reviewed. In the second section, we discuss the continuum appearance of spherically symmetric protostars with various masses. Also, we present recent results for the continuum appearance of an axially symmetric protostellar cloud. The third section deals with the line formation problem and describes preliminary results for a OH molecule in an axially symmetric collapsing cloud. Then we review recent theoretical and observational results obtained for the last evolutionary phase of protostars, known as the YY Orionis phase, when the stellar core first becomes visible in the optical range. Some of the new results and conclusions presented here can be summarized as follows: Rotating collapsing clouds are in general less luminous and cooler than corresponding non-rotating clouds - due to the longer evolutionary time scale. Nevertheless, high resolution studies (resolution [de

Lightness dependence of achromatic loci in color-appearance coordinates

2015-02-01

Full Text Available Shifts in the appearance of color under different illuminant chromaticity are known to be incomplete, and fit nicely with a simple linear transformation of cone responses that aligns the achromatic points under two illuminants. Most chromaticity-transfer functions with von-Kries-like transformations use only one set of values to fit the color shifts from one illuminant to another. However, an achromatic point shifts its chromaticity depending on the lightness of the test stimulus. This lightness dependence of the achromatic-point locus is qualitatively similar to a phenomenon known as the Helson-Judd effect. The present study suggests that the lightness dependency of achromatic points appears to be a general trend, which is supported by the results from deriving the optimal von-Kries coefficients for different lightness levels that best fit the color shifts under different illuminant chromaticities. Further, we report that such a lightness dependence of the achromatic-point loci can be represented simply as a straight line in coordinates defined using color-appearance models such as CIECAM when normalized for daylight.

CT and radiographic appearance of extracranial Onyx® embolization

International Nuclear Information System (INIS)

Jia, J.B.; Green, C.S.; Cohen, A.J.; Helmy, M.

2015-01-01

Onyx ® (ev3, Irvine, CA, USA) is a liquid embolic agent composed of ethylene vinyl alcohol copolymer dissolved in dimethyl sulphoxide used for the treatment of intracranial arteriovenous malformations. Onyx is a preferred embolizing agent due to its unique properties, non-adhesive nature, and durability. In addition to its approved intracranial application, Onyx is also being used successfully in extracranial embolization in areas including extracranial aneurisms and vascular malformations, trauma, gastrointestinal bleeding, and neoplasms. Because of its increasing utilization, it is important for reporting radiologists to be able to recognize its extracranial appearance across different imaging techniques and to be familiar with its uses. The goal of this review is to describe the extracranial uses of Onyx and its appearance in various extracranial locations at radiography and CT, while providing didactic examples. Onyx appears radiodense at CT and plain radiography and has a curvilinear pattern following the expected path of the vessel embolized. At CT, Onyx creates streak artefact that may obstruct the view of surrounding tissues consistent with descriptions of other tantalum devices

Messages about appearance, food, weight and exercise in "tween" television.

Simpson, Courtney C; Kwitowski, Melissa; Boutte, Rachel; Gow, Rachel W; Mazzeo, Suzanne E

2016-12-01

Tweens (children ages ~8-14years) are a relatively recently defined age group, increasingly targeted by marketers. Individuals in this age group are particularly vulnerable to opinions and behaviors presented in media messages, given their level of cognitive and social development. However, little research has examined messages about appearance, food, weight, and exercise in television specifically targeting tweens, despite the popularity of this media type among this age group. This study used a content analytic approach to explore these messages in the five most popular television shows for tweens on the Disney Channel (as of 2015). Using a multiple-pass approach, relevant content in episodes from the most recently completed seasons of each show was coded. Appearance related incidents occurred in every episode; these most frequently mentioned attractiveness/beauty. Food related incidents were also present in every episode; typically, these situations were appearance and weight neutral. Exercise related incidents occurred in 53.3% of episodes; the majority expressed resistance to exercise. Weight related incidents occurred in 40.0% of the episodes; the majority praised the muscular ideal. Women were more likely to initiate appearance incidents, and men were more likely to initiate exercise incidents. These results suggest that programs specifically marketed to tweens reinforce appearance ideals, including stereotypes about female attractiveness and male athleticism, two constructs linked to eating pathology and body dissatisfaction. Given the developmental vulnerability of the target group, these findings are concerning, and highlight potential foci for prevention programming, including media literacy, for tweens.

Full Text Available The association of an α-2 agonist to an anesthetic protocol leads to deep sedation, muscle relaxation and potent analgesia, reducing the quantity of other anesthetic agents to reach the ideal anesthetic plan to the surgical procedure. This study evaluated comparatively the tranquilization, induction and recovery quality of the isofluoraneanesthesia and xylazine and medetomidine continuous infusion in 16 horses. It was possible to conclude that, in this specie, the medetomidine protocol warrants wider muscle relaxation, better quality of anesthetic induction and recovery, even though it presents the same tranquilization quality of the xylazine protocol.

Medication adherence is related to patient satisfaction with family support. This research aimed to understand the meaning of pharmacotherapy to families of people with major depressive disorder. This qualitative study employed Grounded Theory and Symbolic Interactionism. Seventeen families of people with depression from a Brazilian clinic were included. Data was collected from 2013 to 2014, using open interviews, which were analyzed by open, axial, and selective coding. Medication represented "Tranquility and worry" because it re-established tranquility in family routine, but generated concerns. Thus, families were conflicted and ambivalent about medications, and they interfered with the promotion or impairment of adherence.

Previous research has demonstrated that physician clinical suspicion, determined without assessing fluid appearance, is not adequate to rule out spontaneous bacterial peritonitis (SBP) without fluid testing. To determine the sensitivity of physician clinical suspicion, including a bedside assessment of fluid appearance, in the detection of SBP in Emergency Department (ED) patients undergoing paracentesis. We conducted a prospective, observational study of ED patients with ascites undergoing paracentesis at three academic facilities. The enrolling physician recorded the clinical suspicion of SBP ("none," "low," "moderate," or "high"), and ascites appearance ("clear," "hazy," "cloudy," or "bloody"). SBP was defined as an absolute neutrophil count ≥ 250 cells/mm(3), or culture pathogen growth. We defined "clear" ascites fluid as negative for SBP, and "hazy," "cloudy," or "bloody" as positive. A physician clinical suspicion of "none" or "low" was considered negative for SBP, and an assessment of "moderate" or "high" was considered positive. The primary outcome measure was sensitivity of physician clinical impression and ascites appearance for SBP. There were 348 cases enrolled, with SBP diagnosed in 43 (12%). Physician clinical suspicion had a sensitivity of 42% (95% confidence interval [CI] 29-55%) for the detection of SBP. Fluid appearance had a sensitivity of 72% (95% CI 58-83%). Physician clinical impression, which included an assessment of fluid appearance, had poor sensitivity for the detection of SBP and cannot be used to exclude the diagnosis. Routine laboratory fluid analysis is indicated after ED paracentesis, even in patients considered to have a low degree of suspicion for SBP. Copyright © 2013 Elsevier Inc. All rights reserved.

Delayed appearance of tracer lead in facial hair

International Nuclear Information System (INIS)

Rabinowitz, M.; Wetherill, G.; Kopple, J.

1976-01-01

Three adult men were fed 204 Pb--a rare, stable isotope of lead--daily for about 100 days. Simultaneous blood and facial hair measurements of this tracer and of total lead concentrations were made by mass spectrometric isotope dilution analysis. Although the blood showed an immediate response to the intake of the tracer, the facial hair showed a more gradual response and a delay of approximately 35 days. Since the pattern of appearance of lead in hair does not appear to represent a simple time delay of blood lead concentration, the existence of a physiological pool of lead fed by the blood and giving rise to the content in hair is suggested. Hair lead values should therefore, be interpreted as the integral of the blood lead values over the mean life of this intermediate pool--about 100 days

Evaluating comparative and equality judgments in contrast perception: attention alters appearance.

Science.gov (United States)

Anton-Erxleben, Katharina; Abrams, Jared; Carrasco, Marisa

2010-09-09

Covert attention not only improves performance in many visual tasks but also modulates the appearance of several visual features. Studies on attention and appearance have assessed subjective appearance using a task contingent upon a comparative judgment (e.g., M. Carrasco, S. Ling, & S. Read, 2004). Recently, K. A. Schneider and M. Komlos (2008) questioned the validity of those results because they did not find a significant effect of attention on contrast appearance using an equality task. They claim that such equality judgments are bias-free whereas comparative judgments are bias-prone and propose an alternative interpretation of the previous findings based on a decision bias. However, to date there is no empirical support for the superiority of the equality procedure. Here, we compare biases and sensitivity to shifts in perceived contrast of both paradigms. We measured contrast appearance using both a comparative and an equality judgment. Observers judged the contrasts of two simultaneously presented stimuli, while either the contrast of one stimulus was physically incremented (Experiments 1 and 2) or exogenous attention was drawn to it (Experiments 3 and 4). We demonstrate several methodological limitations of the equality paradigm. Nevertheless, both paradigms capture shifts in PSE due to physical and perceived changes in contrast and show that attention enhances apparent contrast.

Victimization, social anxiety, and body dysmorphic concerns: appearance-based rejection sensitivity as a mediator.

Science.gov (United States)

Lavell, Cassie H; Zimmer-Gembeck, Melanie J; Farrell, Lara J; Webb, Haley

2014-09-01

Body dysmorphic disorder (BDD) is characterized by extreme preoccupation with perceived deficits in physical appearance, and sufferers experience severe impairment in functioning. Previous research has indicated that individuals with BDD are high in social anxiety, and often report being the victims of appearance-based teasing. However, there is little research into the possible mechanisms that might explain these relationships. The current study examined appearance-based rejection sensitivity as a mediator between perceived appearance-based victimization, social anxiety, and body dysmorphic symptoms in a sample of 237 Australian undergraduate psychology students. Appearance-based rejection sensitivity fully mediated the relationship between appearance-based victimization and body dysmorphic symptoms, and partially mediated the relationship between social anxiety and body dysmorphic symptoms. Findings suggest that individuals high in social anxiety or those who have a history of more appearance-based victimization may have a bias towards interpreting further appearance-based rejection, which may contribute to extreme appearance concerns such as BDD.

To assess the clinical and pathologic features of each type of intrahepatic cholangiocarcinoma, which is divided into three types according to gross appearance, and to determine the efficacy of CT in detecting this tumor. The pathologic and CT features of 53 surgically proven cases of intrahepatic cholangio-carcinoma were reviewed. On the basis of their gross appearance, the tumors were divided into three types, as follows : mass forming (n=33), periductal infiltrating (n=6), and intraductal growth type (n=14). CT scans were analyzed for sensitivity of detection and correlation between a tumors appearance and its histopathology. The most common histopathologic feature of mass forming and periductal infiltrating type was tubular adenocarcinoma, while in the intraductal growth type, papillary adenocarcinoma (100%) was common. With regard to pattern of tumor spread, intrahepatic and lymph node metastasis were more common in the mass forming and periductal infiltrating type than in the intraductal growth type. CT findings including intrahepatic mass, ductal wall thickening or intraductal mass associated with segmental dilatation of intrahepataic bile ducts, corresponded with these morphologic types. This classification according to gross appearance is of considerable value when interpreting the pathologic features of intrahepatic cholangiocarcinoma. CT seems to be a useful modality for the detection of tumors and may be consistent with their gross morphologic findings

To evaluate the contributions of weight status, skin tone, peer teasing, and parental appraisals of child's size to self-esteem and psychosocial adjustment in overweight African American children. Overweight to very obese 5- to 10-year-old African American children (N = 117) completed measures of self-esteem, skin tone satisfaction, peer teasing, and body size perception. Caregivers completed the Child Behavior Checklist and rated their child's body size. Overweight was associated with low appearance self-esteem, and body size dissatisfaction with low global self-worth and low appearance self-esteem in children 8 and older. Appearance self-esteem but not global self-worth was lower in girls than boys. Parental perception of child's size as heavier than average was associated with low child appearance self-esteem. Heavier children also had more parental report of behavior and psychosocial problems, but their scores were in the nonclinical range. Child skin tone dissatisfaction was associated with low global self-worth. Weight-related peer teasing was associated with low self-esteem. The relationship between obesity and self-esteem in African American children depends upon age, gender, and children's experiences with teasing and parental evaluation of their size. Other factors, like skin tone satisfaction, contribute to a child's sense of self-worth.

Size, shape, and appearance of the normal female pituitary gland

1984-01-01

One hundred seven women 18-65 years old were studied who were referred for suspected central nervous system disease not related to the pituitary gland or hypothalamus. High-resolution, direct, coronal, contrast-enhanced computed tomography (CT) was used to examine the size; shape, and density of the normal pituitary gland. There were three major conclusions: (1) the height of the normal gland can be as much as 9 mm; (2) the superior margin of the gland may bulge in normal patients; and (3) both large size and convex contour appear to be associated with younger age. It was also found that serum prolactin levels do not appear to correlate with the CT appearances. Noise artifacts inherent in high-detail, thin-section, soft-tissue scanning may be a limiting factor in defining reproducible patterns in different parts of the normal pituitary gland

Methaqualone (2-methyl-3-o-tolyl-4(3H)-quinazolinone) is a hypnotic/sedative, chemically unrelated to other groups of sleep-inducing drugs or major tranquilizers. Measurements have been made of the distribution of radioactive methaqualone in the rat brain up to 24 h after oral administration of the drug. Peak tissue concentrations were found 3 h after intubation. The highest concentrations appeared in the optic chiasm, pituitary gland, and reticular formation of the medulla oblongata. Serum concentrations were approximately one order of magnitude higher than those found in the brain. An apparently inert metabolite was found at 24 h in concentrations which were double those of the peak tissue levels of the compound, both in the brain and in the sera. (U.K.)

Muñoz, S

1993-01-01

The nineteenth century sees the rise of the bourgeoisie to social and political power. The values of this class increased the attention paid to certain branches of the medical sciences, such as for example hygiene. A set of rules and methods to achieve better health and, at the same time, to come closer to the perfect image of man described by writers of aesthetics, often taking classical Greece as a point of reference, are believed to be found in these branches. In these strategies physical exercise plays a role which is positively valued as much by hygienists as by philosophers, some of whose works are studied in this article.

The Functionality of Facial Appearance and Its Importance to a Korean Population

Young Jun Kim

2013-11-01

Full Text Available BackgroundMany people have an interest in the correction of facial scars or deformities caused by trauma. The increasing ability to correct such flaws has been one of the reasons for the increase in the popularity of facial plastic surgery. In addition to its roles in communication, breathing, eating, olfaction and vision, the appearance of the face also plays an important role in human interactions, including during social activities. However, studies on the importance of the functional role of facial appearance. As a function of the face are scare. Therefore, in the present study, we evaluated the importance of the functions of the face in Korea.MethodsWe conducted an online panel survey of 300 participants (age range, 20-70 years. Each respondent was administered the demographic data form, Facial Function Assessment Scale, Rosenberg Self-Esteem Scale, and standard gamble questionnaires.ResultsIn the evaluation on the importance of facial functions, a normal appearance was considered as important as communication, breathing, speech, and vision. Of the 300 participants, 85% stated that a normal appearance is important in social activities.ConclusionsThe results of this survey involving a cross-section of the Korean population indicated that a normal appearance was considered one of the principal facial functions. A normal appearance was considered more important than the functions of olfaction and expression. Moreover, a normal appearance was determined to be an important facial function for leading a normal life in Korea.

Visual Appearance-Based Unmanned Vehicle Sequential Localization

2013-01-01

Full Text Available Localizationis of vital importance for an unmanned vehicle to drive on the road. Most of the existing algorithms are based on laser range finders, inertial equipment, artificial landmarks, distributing sensors or global positioning system(GPS information. Currently, the problem of localization with vision information is most concerned. However, vision-based localization techniquesare still unavailable for practical applications. In this paper, we present a vision-based sequential probability localization method. This method uses the surface information of the roadside to locate the vehicle, especially in the situation where GPS information is unavailable. It is composed of two step, first, in a recording stage, we construct a ground truthmap with the appearance of the roadside environment. Then in an on-line stage, we use a sequential matching approach to localize the vehicle. In the experiment, we use two independent cameras to observe the environment, one is left-orientated and the other is right. SIFT features and Daisy features are used to represent for the visual appearance of the environment. The experiment results show that the proposed method could locate the vehicle in a complicated, large environment with high reliability.

Rapid Material Appearance Acquisition Using Consumer Hardware

Directory of Open Access Journals (Sweden)

Jiří Filip

2014-10-01

Full Text Available A photo-realistic representation of material appearance can be achieved by means of bidirectional texture function (BTF capturing a material’s appearance for varying illumination, viewing directions, and spatial pixel coordinates. BTF captures many non-local effects in material structure such as inter-reflections, occlusions, shadowing, or scattering. The acquisition of BTF data is usually time and resource-intensive due to the high dimensionality of BTF data. This results in expensive, complex measurement setups and/or excessively long measurement times. We propose an approximate BTF acquisition setup based on a simple, affordable mechanical gantry containing a consumer camera and two LED lights. It captures a very limited subset of material surface images by shooting several video sequences. A psychophysical study comparing captured and reconstructed data with the reference BTFs of seven tested materials revealed that results of our method show a promising visual quality. Speed of the setup has been demonstrated on measurement of human skin and measurement and modeling of a glue dessication time-varying process. As it allows for fast, inexpensive, acquisition of approximate BTFs, this method can be beneficial to visualization applications demanding less accuracy, where BTF utilization has previously been limited.

When an Object Appears Unexpectedly: Object Circumvention in Adults.

Wilmut, Kate; Du, Wenchong; Barnett, Anna L

2017-01-01

Obstacles often appear unexpectedly in our pathway and these require us to make immediate adjustments. Despite how regularly we encounter such situations only few studies have considered how we adjust to unexpected obstacles in the pathway that require us to walk around them. The authors considered how adults adjust to the possibility of an obstacle appearing and then also how foot placement is adjusted to circumvent an obstacle. Fifteen healthy adults walked down an 11-m walkway, initially they were told this was a clear pathway and nothing in the environment would change (no gate), they then performed a series of trials in which a gate may (gate close) or may not (gate open) partially obstruct their pathway. The authors found that mediolateral trunk velocity and acceleration was significantly increased when there was the possibility of an obstacle but before the obstacle appeared. This demonstrates an adaptive walking strategy that seems to enable healthy young adults to successfully circumvent obstacles. The authors also categorized foot placement adjustments and found that adults favored making shorter and wider steps away from the obstacle. They suggest this combination of adjustments allows participants to maintain stability while successfully circumventing the obstacle.

Perceived functional impact of abnormal facial appearance.

Science.gov (United States)

Rankin, Marlene; Borah, Gregory L

2003-06-01

Functional facial deformities are usually described as those that impair respiration, eating, hearing, or speech. Yet facial scars and cutaneous deformities have a significant negative effect on social functionality that has been poorly documented in the scientific literature. Insurance companies are declining payments for reconstructive surgical procedures for facial deformities caused by congenital disabilities and after cancer or trauma operations that do not affect mechanical facial activity. The purpose of this study was to establish a large, sample-based evaluation of the perceived social functioning, interpersonal characteristics, and employability indices for a range of facial appearances (normal and abnormal). Adult volunteer evaluators (n = 210) provided their subjective perceptions based on facial physical appearance, and an analysis of the consequences of facial deformity on parameters of preferential treatment was performed. A two-group comparative research design rated the differences among 10 examples of digitally altered facial photographs of actual patients among various age and ethnic groups with "normal" and "abnormal" congenital deformities or posttrauma scars. Photographs of adult patients with observable congenital and posttraumatic deformities (abnormal) were digitally retouched to eliminate the stigmatic defects (normal). The normal and abnormal photographs of identical patients were evaluated by the large sample study group on nine parameters of social functioning, such as honesty, employability, attractiveness, and effectiveness, using a visual analogue rating scale. Patients with abnormal facial characteristics were rated as significantly less honest (p = 0.007), less employable (p = 0.001), less trustworthy (p = 0.01), less optimistic (p = 0.001), less effective (p = 0.02), less capable (p = 0.002), less intelligent (p = 0.03), less popular (p = 0.001), and less attractive (p = 0.001) than were the same patients with normal facial

Full Text Available Objectives: The purpose of this study is to make questionnaire for screening body dysmorphic disorder sufferers in cosmetic clinics. Methods: A sample of 150 female patients with age average 29.4 years completed Physical Appearance Concern Questionnaire. It has been used as screening tool for screening patients with body dysmorphic disorder symptoms in cosmetic clinics. Results: Result of reliability analysis (α=0.908 and validity have shown the effectiveness of this questionnaire for recognizing individuals with BDD symptoms. Discussion: Physical appearance concern questionnaire can be used in cosmetic clinics for identifying BDD sufferers among clients, with score for the severity of symptoms. Almost all of the researches have been studying in cosmetic clinics or dermatology settings and there is no investigation for people with special needs, thus further research is required in the development of a screening questionnaire or interview for identifying patients with BDD with special needs.

Color Appearance of the Neon Color Spreading Effect

2017-04-01

Full Text Available As a part of this paper, the influence of various parameters within the target process of graphic reproduction on the color appearance of the neon color spreading effect was investigated. The shift in a color appearance qualitatively is determined through the calculation of changes in perceptual attributes of color, i.e. differences in lightness, chroma and hue. The influence of different media (printed images, and LCD display in the “cross-media” system was examined, as well as the role of the inserted segment color choice and background of the primary stimulus as an element of design solutions. These parameters were evaluated in a variety of ambient conditions and under the observation of three CIE standard light sources and illuminants. It was found that it was mostly the changes of the chroma and lightness. The change in the color hue is the lowest.

Full Text Available The impact of forced social comparison on adolescents’ self-esteem and appearance satisfaction research, conducted on a sample of 133 high school seniors, consisted of two phases. In phase one, participants were given the Rosenberg Self-Esteem Inventory, Appearance Satisfaction Scale and Appearance Relevance Scale, and in phase two, one month later, they were exposed to photographs of attractive and unattractive individuals. Two groups of boys and girls each assessed attractive or unattractive individuals of their own gender, while two control groups (of both genders were not exposed to any photographs. Immediately after assessing the photographs, the participants were again given the Rosenberg Self-Esteem Inventory and Appearance Satisfaction Scale. We found that forced social comparison had an impact on self-esteem and a marginally significant effect on appearance satisfaction in the group of participants (of both genders assessing the photographs of unattractive individuals, while no effects were found in the either the control group or the group assessing the photographs of attractive individuals. We also examined the impact of self-esteem, appearance satisfaction and appearance relevance as moderating variables on the effect size of social comparison and showed that higher pretest self-esteem and appearance relevance and lower appearance satisfaction predict higher posttest self-esteem scores, regardless of the participants’ group membership. The group of participants exposed to photographs of unattractive people, however, showed the opposite pattern - those participants who had initially lower self-esteem have increased it more as a result of the experimental exposure.

Fooled by First Impressions? Reexamining the Diagnostic Value of Appearance-Based Inferences

OpenAIRE

2010-01-01

Abstract We often form opinions about the characteristics of others from single, static samples of their appearance --the very first thing we see when, or even before, we meet them. These inferences occur spontaneously, rapidly, and can impact decisions in a variety of important domains. A crucial question, then, is whether appearance-based inferences are accurate. Using a naturalistic data set of more than 1 million appearance-based judgments obtained from a popular website (Study...

two different narrative matrices: "The Lady Ghost" in its different names, and "the Nahuelito", an Argentine version of the Loch Monster. Stories collected in different contexts and formats are examined, including media. The research focuses on the dynamics between scientific and narrative knowledge, which deals with the semantic domain of collective beliefs. These are understood as modal expressions, whose truth values rely on an intersubjective agreement. In this regard, ghostly apparitions and lock monsters can be considered rhetoric expressions of beliefs about the supernatural. These metaphoric creatures, in fact, tend to provide more satisfactory explanations about the symbolic sphere of experience than modern science.

Scintigraphic appearance of the piriformis muscle syndrome

This is the first report in the nuclear medicine literature of the scintigraphic appearance of the piriformis muscle syndrome. This syndrome previously has been thought to be a purely clinical diagnosis and imaging modalities have been ignored. However, its confusing clinical presentation can lead to unnecessary surgical exploration. This case is presented to illustrate the characteristic scintigraphic pattern and suggest the role of nuclear medicine scanning in establishing the diagnosis

MRI appearance of muscle denervation

Muscle denervation results from a variety of causes including trauma, neoplasia, neuropathies, infections, autoimmune processes and vasculitis. Traditionally, the diagnosis of muscle denervation was based on clinical examination and electromyography. Magnetic resonance imaging (MRI) offers a distinct advantage over electromyography, not only in diagnosing muscle denervation, but also in determining its aetiology. MRI demonstrates characteristic signal intensity patterns depending on the stage of muscle denervation. The acute and subacutely denervated muscle shows a high signal intensity pattern on fluid sensitive sequences and normal signal intensity on T1-weighted MRI images. In chronic denervation, muscle atrophy and fatty infiltration demonstrate high signal changes on T1-weighted sequences in association with volume loss. The purpose of this review is to summarise the MRI appearance of denervated muscle, with special emphasis on the signal intensity patterns in acute and subacute muscle denervation. (orig.)

We describe the ultrasound appearance of knuckle pads. Retrospective analysis of imaging in a series of five patients initially referred for evaluation of periarticular soft-tissue swelling of the hands involving the dorsum of the PIP and MP joints. Two patients had associated Dupuytren's contractures. Ultrasound and radiographs of the hands in all patients were reviewed and correlated with clinical history and physical exams. Radiographs in four patients demonstrated dorsal soft-tissue thickening. Ultrasound exams showed increased dorsal subcutaneous thickening, with either diffuse or focal hypoechoic areas corresponding to the areas of soft-tissue fullness identified on physical exam. No erosions or synovial proliferation were identified either by radiographs or ultrasound of the underlying joints. Knuckle pads can sometimes be difficult to distinguish from synovitis on physical examination. Musculoskeletal ultrasound can quickly identify these superficial lesions and exclude underlying synovial proliferation.

Computed tomography appearances in the linear sebaceous naevus syndrome

International Nuclear Information System (INIS)

Levin, S.; Robinson, R.O.; Aicardi, J.; Hoare, R.D.

1984-01-01

The appearance of C.T. of the head in 11 cases of the linear sebaceous naevus syndrome are presented. From these it is argued that the pathology represents a disorder of neuronal migration and organisation rather than differentiation. Since three of the cases had evidence of CNS tumour in addition to two in the literature, it would appear that a further aspect of this disorder is a failure of growth constraint. This is paralleled by a similar tendency in the skin lesion which should be considered premalignant. Normal intelligence is rare in this condition and co-exists only with a normal C.T. scan. The early onset of fits is not necessarily associated with subsequent mental handicap. (orig.)

Eyewitness lineups: is the appearance-change instruction a good idea?

Science.gov (United States)

Charman, Steve D; Wells, Gary L

2007-02-01

The Department of Justice's Guide for lineups recommends warning eyewitnesses that the culprit's appearance might have changed since the time of the crime. This appearance-change instruction (ACI) has never been empirically tested. A video crime with four culprits was viewed by 289 participants who then attempted to identify the culprits from four 6-person arrays that either included or did not include the culprit. Participants either received the ACI or not and all were warned that the culprit might or might not be in the arrays. The culprits varied in how much their appearance changed from the video to their lineup arrays, but the ACI did not improve identification decisions for any of the lineups. Collapsed over the four culprits, the ACI increased false alarms and filler identifications but did not increase culprit identifications. The ACI reduced confidence and increased response latency. Two processes that could account for these results are discussed, namely a decision criterion shift and a general increase in ecphoric similarity.

Textiles are mainly used for decoration and protection. In both cases, their original appearance and its retention are important factors for customers. Therefore, evaluation of appearance parameters are critical for quality assurance purposes, during and after manufacturing, to determine the lifetime and/or beauty of textile products. In particular, appearance retention of textile products is commonly certified with grades, which are currently assigned by human experts. However, manufacturers would prefer a more objective system. We present an objective system for grading appearance retention, particularly, for textile floor coverings. Changes in appearance are quantified by using linear regression models on texture features extracted from intensity and range images. Range images are obtained by our own laser scanner, reconstructing the carpet surface using two methods that have been previously presented. We extract texture features using a variant of the local binary pattern technique based on detecting those patterns whose frequencies are related to the appearance retention grades. We test models for eight types of carpets. Results show that the proposed approach describes the degree of wear with a precision within the range allowed to human inspectors by international standards. The methodology followed in this experiment has been designed to be general for evaluating global deviation of texture in other types of textiles, as well as other surface materials.

Media-portrayed idealized images, body shame, and appearance anxiety.

Monro, Fiona; Huon, Gail

2005-07-01

This study was designed to determine the effects of media-portrayed idealized images on young women's body shame and appearance anxiety, and to establish whether the effects depend on advertisement type and on participant self-objectification. Participants were 39 female university students. Twenty-four magazine advertisements comprised 12 body-related and 12 non-body-related products, one half of each with, and the other one half without, idealized images. Preexposure and post exposure body shame and appearance anxiety measures were recorded. Appearance anxiety increased after viewing advertisements featuring idealized images. There was also a significant interaction between self-objectification level and idealized body (presence vs. absence). No differences emerged for body-related compared with non-body-related product advertisements. The only result for body shame was a main effect for time. Participants' body shame increased after exposure to idealized images, irrespective of advertisement type. Although our findings reveal that media-portrayed idealized images detrimentally affect the body image of young women, they highlight the individual differences in vulnerability and the different effects for different components of body image. These results are discussed in terms of their implications for the prevention and early intervention of body image and dieting-related disorders. ( Copyright 2005 by Wiley Periodicals, Inc

2013-01-01

Progressive rendering is becoming a popular alternative to precomputational approaches to appearance design. However, progressive algorithms create images exhibiting visual artifacts at early stages. A user study investigated these artifacts' effects on user performance in appearance design tasks. Novice and expert subjects performed lighting and material editing tasks with four algorithms: random path tracing, quasirandom path tracing, progressive photon mapping, and virtual-point-light rendering. Both the novices and experts strongly preferred path tracing to progressive photon mapping and virtual-point-light rendering. None of the participants preferred random path tracing to quasirandom path tracing or vice versa; the same situation held between progressive photon mapping and virtual-point-light rendering. The user workflow didn’t differ significantly with the four algorithms. The Web Extras include a video showing how four progressive-rendering algorithms converged (at http://youtu.be/ck-Gevl1e9s), the source code used, and other supplementary materials.

Purpose: Efficient and accurate 3D liver segmentations from contrast-enhanced computed tomography (CT) images play an important role in therapeutic strategies for hepatic diseases. However, inhomogeneous appearances, ambiguous boundaries, and large variance in shape often make it a challenging task. The existence of liver abnormalities poses further difficulty. Despite the significant intensity difference, liver tumors should be segmented as part of the liver. This study aims to address these challenges, especially when the target livers contain subregions with distinct appearances. Methods: The authors propose a novel multiregion-appearance based approach with graph cuts to delineate the liver surface. For livers with multiple subregions, a geodesic distance based appearance selection scheme is introduced to utilize proper appearance constraint for each subregion. A special case of the proposed method, which uses only one appearance constraint to segment the liver, is also presented. The segmentation process is modeled with energy functions incorporating both boundary and region information. Rather than a simple fixed combination, an adaptive balancing weight is introduced and learned from training sets. The proposed method only calls initialization inside the liver surface. No additional constraints from user interaction are utilized. Results: The proposed method was validated on 50 3D CT images from three datasets, i.e., Medical Image Computing and Computer Assisted Intervention (MICCAI) training and testing set, and local dataset. On MICCAI testing set, the proposed method achieved a total score of 83.4 ± 3.1, outperforming nonexpert manual segmentation (average score of 75.0). When applying their method to MICCAI training set and local dataset, it yielded a mean Dice similarity coefficient (DSC) of 97.7% ± 0.5% and 97.5% ± 0.4%, respectively. These results demonstrated the accuracy of the method when applied to different computed tomography (CT) datasets

Segmentation of brain structures in magnetic resonance images is an important task in neuro image analysis. Several papers on this topic have shown the benefit of supervised classification based on local appearance features, often combined with atlas-based approaches. These methods require...... a representative annotated training set and therefore often do not perform well if the target image is acquired on a different scanner or with a different acquisition protocol than the training images. Assuming that the appearance of the brain is determined by the underlying brain tissue distribution...... with substantially different imaging protocols and on different scanners. While a combination of conventional appearance features trained on data from a different scanner with multiatlas segmentation performed poorly with an average Dice overlap of 0.698, the local appearance model based on the new acquisition...

Body Dysmorphic Symptoms, Functional Impairment, and Depression: The Role of Appearance-Based Teasing.

Science.gov (United States)

Weingarden, Hilary; Renshaw, Keith D

2016-01-01

Body dysmorphic disorder is associated with elevated social and occupational impairment and comorbid depression, but research on risk factors for body dysmorphic symptoms and associated outcomes is limited. Appearance-based teasing may be a potential risk factor. To examine the specificity of this factor, the authors assessed self-reported appearance-based teasing, body dysmorphic, and obsessive-compulsive symptom severity, functional impairment (i.e., social, occupational, family impairment), and depression in a nonclinical sample of undergraduates. As hypothesized, appearance-based teasing was positively correlated with body dysmorphic symptoms. The correlation between teasing and body dysmorphic symptoms was stronger than that between teasing and obsessive-compulsive symptom severity. Last, body dysmorphic symptom severity and appearance-based teasing interacted in predicting functional impairment and depression. Specifically, appearance-based teasing was positively associated with depression and functional impairment only in those with elevated body dysmorphic symptoms. When a similar moderation was tested with obsessive-compulsive, in place of body dysmorphic, symptom severity, the interaction was nonsignificant. Findings support theory that appearance-based teasing is a specific risk factor for body dysmorphic symptoms and associated functional impairment.

Basal peripheral pleuroparenchymal opacities are described on CT of early cryptogenic fibrosing alveolitis, asbestosis and bleomycin pneumonitis. These diseases may be caused by free radical effects on phospholipid metabolism causing cell wall damage. Amiodarone hydrochloride alters phospholipid synthesis metabolically. Amiodarone pneumonitis might be expected to show similar CT appearances. Sixteen patients who have developed new respiratory symptoms while taking amiodarone have been scanned prone and supine and at inspiration and expiration by means of a scanner with 2-mm sections at 1-cm intervals. All have been previously healthy nonsmokers with no relevant occupational history. Previous chest radiographs have been normal. Results are presented

Appearance-related bullying and skin disorders.

Science.gov (United States)

Magin, Parker

2013-01-01

Bullying encompasses verbal aggression, physical aggression, and social exclusion. It involves "harm-doing" that is carried out repeatedly, over time, and within a relationship, involving a power imbalance between the bully and the bullied. Being bullied may have considerable adverse sequelae, including psychologic or psychiatric harm. Much bullying is appearance-related, and it would be surprising if some individuals with skin disease were not bullied given the high visibility of skin diseases. The limited evidence available does suggest that individuals with skin disease, particularly those with acne, psoriasis, and atopic dermatitis, are often bullied, which can adversely affect them psychologically.

MULTISCALE SPARSE APPEARANCE MODELING AND SIMULATION OF PATHOLOGICAL DEFORMATIONS

Directory of Open Access Journals (Sweden)

Rami Zewail

2017-08-01

Full Text Available Machine learning and statistical modeling techniques has drawn much interest within the medical imaging research community. However, clinically-relevant modeling of anatomical structures continues to be a challenging task. This paper presents a novel method for multiscale sparse appearance modeling in medical images with application to simulation of pathological deformations in X-ray images of human spine. The proposed appearance model benefits from the non-linear approximation power of Contourlets and its ability to capture higher order singularities to achieve a sparse representation while preserving the accuracy of the statistical model. Independent Component Analysis is used to extract statistical independent modes of variations from the sparse Contourlet-based domain. The new model is then used to simulate clinically-relevant pathological deformations in radiographic images.

Subcutaneous rheumatoid nodules occur commonly in advanced cases of rheumatoid arthritis, but only rarely appear in the feet. We present a case of a subcutaneous rheumatoid nodule arising in the heel pad of a 68-year-old man with a long history of rheumatoid arthritis, along with a review of the literature. The appearance of the mass on MRI is illustrated and correlated with the histologic findings. The MRI appearance of a subcutaneous rheumatoid nodule is that of a nonspecific ill-defined mass with long T1- and long T2-relaxation times. A differential diagnosis for similar appearing masses is offered. (orig.)

Fashion Evaluation Method for Clothing Recommendation Based on Weak Appearance Feature

Directory of Open Access Journals (Sweden)

Yan Zhang

2017-01-01

Full Text Available With the rapid rising of living standard, people gradually developed higher shopping enthusiasm and increasing demand for garment. Nowadays, an increasing number of people pursue fashion. However, facing too many types of garment, consumers need to try them on repeatedly, which is somewhat time- and energy-consuming. Besides, it is difficult for merchants to master the real-time demand of consumers. Herein, there is not enough cohesiveness between consumer information and merchants. Thus, a novel fashion evaluation method on the basis of the appearance weak feature is proposed in this paper. First of all, image database is established and three aspects of appearance weak feature are put forward to characterize the fashion level. Furthermore, the appearance weak features are extracted according to the characters’ facial feature localization method. Last but not least, consumers’ fashion level can be classified through support vector product, and the classification is verified with the hierarchical analysis method. The experimental results show that consumers’ fashion level can be accurately described based on the indexes of appearance weak feature and the approach has higher application value for the clothing recommendation system.

Misuse of prescription and illicit drugs among high-risk young adults in Los Angeles and New York

Directory of Open Access Journals (Sweden)

Stephen E. Lankenau

2012-02-01

Full Text Available Background. Prescription drug misuse among young adults is increasingly viewed as a public health concern, yet most research has focused on student populations and excluded high-risk groups. Furthermore, research on populations who report recent prescription drug misuse is limited. This study examined patterns of prescription drug misuse among high-risk young adults in Los Angeles (LA and New York (NY, which represent different local markets for illicit and prescription drugs. Design and Methods. Between 2009 and 2011, 596 young adults (16 to 25 years old who had misused prescription drugs within the past 90 days were interviewed in Los Angeles and New York. Sampling was stratified to enroll three groups of high-risk young adults: injection drug users (IDUs; homeless persons; and polydrug users. Results. In both sites, lifetime history of receiving a prescription for an opioid, tranquilizer, or stimulant was high and commonly preceded misuse. Moreover, initiation of opioids occurred before heroin and initiation of prescription stimulants happened prior to illicit stimulants. NY participants more frequently misused oxycodone, heroin, and cocaine, and LA participants more frequently misused codeine, marijuana, and methamphetamine. Combining prescription and illicit drugs during drug using events was commonly reported in both sites. Opioids and tranquilizers were used as substitutes for other drugs, e.g., heroin, when these drugs were not available. Conclusion. Patterns of drug use among high-risk young adults in Los Angeles and New York appear to be linked to differences in local markets in each city for illicit drugs and diverted prescription drugs.

Perceiving Direction of a Walker: Effect of Body Appearance

Full Text Available Human can perceive others' walking direction accurately even with 117ms observation (Sato, et al., ECVP2008. We aimed to see whether appearance of walker's body affects the accuracy of perceiving direction of the walker. Thus, we employed three different appearances: realistic human computer-graphics body (CG-human, nonrealistic cylinder-assembled body (Cylinders, and point-light walker (Points. We made a three-dimensional model of an adult-size walker who walked at a place. CG-human stimuli were generated by rendering the model with smooth shading. We made Cylinders stimuli by replacing body parts such as arms, legs, head, and hands with cylinders. Points stimuli were made by tracking 18 positions (mostly joints of the body like biological motion. One of walkers was presented for 117, 250, 500 or 1000ms while its direction was randomly varied by 3deg steps to 21deg left or right. Observers judged whether the walker was walking toward them (hit or not (miss, and self-range was measured in terms of the standard deviation for hit distributions. The perceived self-range was narrowed with long duration, and with CG-human stimulus. It is suggested that the accuracy of perceiving walker's direction depends on body appearance, and it is higher for human-like body than nonhuman body.

Body actions change the appearance of facial expressions.

Directory of Open Access Journals (Sweden)

Carlo Fantoni

Full Text Available Perception, cognition, and emotion do not operate along segregated pathways; rather, their adaptive interaction is supported by various sources of evidence. For instance, the aesthetic appraisal of powerful mood inducers like music can bias the facial expression of emotions towards mood congruency. In four experiments we showed similar mood-congruency effects elicited by the comfort/discomfort of body actions. Using a novel Motor Action Mood Induction Procedure, we let participants perform comfortable/uncomfortable visually-guided reaches and tested them in a facial emotion identification task. Through the alleged mediation of motor action induced mood, action comfort enhanced the quality of the participant's global experience (a neutral face appeared happy and a slightly angry face neutral, while action discomfort made a neutral face appear angry and a slightly happy face neutral. Furthermore, uncomfortable (but not comfortable reaching improved the sensitivity for the identification of emotional faces and reduced the identification time of facial expressions, as a possible effect of hyper-arousal from an unpleasant bodily experience.

Appearance evaluation of others' faces and bodies in anorexia nervosa and body dysmorphic disorder.

Moody, Teena D; Shen, Vivian W; Hutcheson, Nathan L; Henretty, Jennifer R; Sheen, Courtney L; Strober, Michael; Feusner, Jamie D

2017-02-01

Individuals with anorexia nervosa (AN) and body dysmorphic disorder (BDD) exhibit distorted perception and negative evaluations of their own appearance; however, little is known about how they perceive others' appearance, and whether or not the conditions share perceptual distortions. Thirty participants with BDD, 22 with AN, now weight-restored, and 39 healthy comparison participants (HC) rated photographs of others' faces and bodies on attractiveness, how overweight or underweight they were, and how much photographs triggered thoughts of their own appearance. We compared responses among groups by stimulus type and by level-of-detail (spatial frequency). Compared to HCs, AN and BDD had lower attractiveness ratings for others' bodies and faces for high-detail and low-detail images, rated bodies as more overweight, and were more triggered to think of their own appearance for faces and bodies. In AN, symptom severity was associated with greater triggering of thoughts of own appearance and higher endorsement of overweight ratings for bodies. In BDD, symptom severity was associated with greater triggering of thoughts of own appearance for bodies and higher overweight ratings for low-detail images. BDD was more triggered to think of own facial appearance than AN. AN and BDD show similar behavioral phenotypes of negative appearance evaluations for others' faces and bodies, and have thoughts of their own appearance triggered even for images outside of their primary appearance concerns, suggesting a more complex cross-disorder body-image phenotype than previously assumed. Future treatment strategies may benefit from addressing how these individuals evaluate others in addition to themselves. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:127-138). © 2016 Wiley Periodicals, Inc.

Computed tomography is very useful for recognition of retained sponges. The appearance of retained sponges is widely variable. Air trapping into a surgical sponge results in the spongiform pattern which is characteristic but unfortunately uncommon. A low-density, high-density, or complex mass is found in the majority of cases, but these patterns are not specific. Sometimes, a thin high-density capsule may be seen.

Liu, Daniel; Perera, Warren; Schlicht, Stephen; Choong, Peter; Slavin, John; Pianta, Marcus

2015-01-01

This study aimed to discuss the role medical imaging has on diagnosis of musculoskeletal desmoid tumours and to describe their radiological appearances on various imaging modalities. Imaging of histologically proven cases of desmoid tumours at St. Vincent's Hospital Melbourne were obtained via picture archiving communication system (PACS) and then assessed by two musculoskeletal radiologists. Suitable imagings were obtained from PACS. All imaging chosen was de-identified. Desmoid tumours can occur in many areas of the body. Imaging plays an important role in the diagnosis of these tumours and magnetic resonance imaging has been the gold standard for imaging and is the most accurate in terms of assessing tumour margins and involvement of surrounding structure.

Epilepsy postings on YouTube: exercising individuals' and organizations' right to appear.

Science.gov (United States)

Kerson, Toba Schwaber

2012-01-01

Philosopher Hannah Arendt maintains that everyone has the right to appear in public as an embodied, singular individual. Because of the stigma attached to epilepsy, many with this condition are denied this right. Using grounded theory techniques, the author analyzes uploads of epilepsy on YouTube. The author argues that personal uploads on YouTube are the only mass media examples in which those with epilepsy can exercise their right to appear without the interpretation of intermediaries. Emerging themes relating to "the right to appear" allow social workers to deepen understanding of this and other devastating, often invisible and sometimes life-threatening illnesses.

The relationship between media exposure and antifat attitudes: the role of dysfunctional appearance beliefs.

Science.gov (United States)

Lin, Linda; Reid, Kathleen

2009-01-01

This study examined the relationship between media exposure, antifat attitudes, and body dissatisfaction, as well as the mediating effect of dysfunctional appearance beliefs. A sample of 112 women completed surveys measuring media exposure, antifat attitudes, body dissatisfaction, and dysfunctional beliefs about appearance. It was found that time spent reading fashion magazines was positively correlated with antifat attitudes and that this relationship was mediated by dysfunctional beliefs about appearance. Measures of antifat attitudes and body dissatisfaction were both found to be correlated with endorsement of dysfunctional beliefs about appearance and body mass index. Results suggest that time spent reading fashion magazines may be related to antifat attitudes through dysfunctional appearance beliefs.

Development of the Multiple Gene Knockout System with One-Step PCR in Thermoacidophilic Crenarchaeon Sulfolobus acidocaldarius

2017-01-01

Full Text Available Multiple gene knockout systems developed in the thermoacidophilic crenarchaeon Sulfolobus acidocaldarius are powerful genetic tools. However, plasmid construction typically requires several steps. Alternatively, PCR tailing for high-throughput gene disruption was also developed in S. acidocaldarius, but repeated gene knockout based on PCR tailing has been limited due to lack of a genetic marker system. In this study, we demonstrated efficient homologous recombination frequency (2.8 × 104 ± 6.9 × 103 colonies/μg DNA by optimizing the transformation conditions. This optimized protocol allowed to develop reliable gene knockout via double crossover using short homologous arms and to establish the multiple gene knockout system with one-step PCR (MONSTER. In the MONSTER, a multiple gene knockout cassette was simply and rapidly constructed by one-step PCR without plasmid construction, and the PCR product can be immediately used for target gene deletion. As an example of the applications of this strategy, we successfully made a DNA photolyase- (phr- and arginine decarboxylase- (argD- deficient strain of S. acidocaldarius. In addition, an agmatine selection system consisting of an agmatine-auxotrophic strain and argD marker was also established. The MONSTER provides an alternative strategy that enables the very simple construction of multiple gene knockout cassettes for genetic studies in S. acidocaldarius.

Beauty and the burn: tanning and other appearance-altering attitudes and behaviors.

Tanning is often prompted by appearance concerns, yet little is known about associations between tanning and other appearance-altering behaviors. In the current study, we examined potential correlates of indoor and outdoor tanning that, like tanning, may enhance appearance but present health risks. College students (N = 284; Mage = 20.14, SD = 3.39) completed a survey. The main outcome measures were indoor tanning and outdoor sunbathing. Participants also answered questions pertaining to piercings and tattoos, healthy and unhealthy dieting behaviors, cigarette smoking, and interest in cosmetic surgery and enhancements. Results indicate that indoor tanners were more likely to have piercings, tattoos, to engage in healthy dieting behaviors, and to express interest in cosmetic enhancements. Outdoor sunbathers were more interested in cosmetic enhancements than non-outdoor sunbathers, and female outdoor sunbathers reported more unhealthy dieting behaviors than male outdoor sunbathers. These findings provide evidence for college students' engagement in a constellation of appearance-oriented risk behaviors.

1998-01-01

Purpose: We evaluated the frequency, distribution and appearance of benign lesions in 18 F-PET scans. Methods: Between March 1996 and May 1997, 18 F-PET scans were performed in 59 patients in addition to conventional planar bone scintigraphy. Eleven patients were subjected to additional SPECT imaging. The main indication was searching for bone metastases (58 pat.). The diagnosis was confirmed radiologically. Results: With 18 F-PET in 39 patients (66,1%) 152 benign lesions, mostly located in the spine were detected. 99m Tc bone scans revealed 45 lesions in 10 patients. Osteoarthritis of the intervertebral articulations (69%) or of the acromioclavicular joint (15%) were the most common reasons for degenerative lesions detected with 18 F-PET. Osteophytes appeared as hot lesions located at two adjacent vertebral endplates. Osteoarthritis of the intervertebral articulations showed an enhanced tracer uptake at these localizations, whereas endplate fractures of the vertebral bodies appeared very typically; solitary fractures of the ribs could not be differentiated from metastases. Rare benign lesions were not studied. Conclusion: Most of the degenerative lesions (84%) detected with 18 F-PET had a very typical appearance and could be detected with the improved spatial resolution and advantages of a tomographic technique. 18 F-PET had an increased accuracy in detecting degenerative bone lesions.

2008-01-01

Adenocarcinomas are often diagnosed as old inflammatory lesions which are sometimes overlooked. Some of these adenocarcinomas display characteristic thin-section computed tomography (TS-CT) findings. We reported on these bubble-like appearances (BLA). We studied the BLA characteristics of adenocarcinomas. We reviewed the TS-CT findings of 17 (6 men, 11 women) cases of adenocarcinoma with bubble-like appearances. All 17 patients had undergone surgery between August 2003 and March 2007. We studied correlations between the TS-CT findings, the pathological findings and the clinical characteristics. The average tumor diameter was 35.4 mm. The definition of BLA is; having a irregular shape with straight margins, peripheral ground-glass opacity (GGO), dilated air bronchograms (more than 3), prominent pleural indentation. The pathological characteristics of tumors with BLA were; peripheral bronchioloalveolar cell carcinoma (BAC) patterns, almost total collapse (about 80% of the tumor area), and several ectatic small bronchi. Six cases were initially overlooked, because the TS-CT findings appeared as old inflammation. The average tumor doubling time was 1167 days. After resection, there have been no recurrences. On TS-CT images, BLA type adenocarcinomas appear as irregular in shape and they have a very slow doubling time. These types of lesions require careful attention because they are often diagnosed as old inflammatory scarring. (author)

Evaluation of appearance transfer and persistence in central face transplantation: a computer simulation analysis.

Pomahac, Bohdan; Aflaki, Pejman; Nelson, Charles; Balas, Benjamin

2010-05-01

Partial facial allotransplantation is an emerging option in reconstruction of central facial defects, providing function and aesthetic appearance. Ethical debate partly stems from uncertainty surrounding identity aspects of the procedure. There is no objective evidence regarding the effect of donors' transplanted facial structures on appearance change of the recipients and its influence on facial recognition of donors and recipients. Full-face frontal view color photographs of 100 volunteers were taken at a distance of 150 cm with a digital camera (Nikon/DX80). Photographs were taken in front of a blue background, and with a neutral facial expression. Using image-editing software (Adobe-Photoshop-CS3), central facial transplantation was performed between participants. Twenty observers performed a familiar 'facial recognition task', to identify 40 post-transplant composite faces presented individually on the screen at a viewing distance of 60 cm, with an exposure time of 5s. Each composite face comprised of a familiar and an unfamiliar face to the observers. Trials were done with and without external facial features (head contour, hair and ears). Two variables were defined: 'Appearance Transfer' refers to transfer of donor's appearance to the recipient. 'Appearance Persistence' deals with the extent of recipient's appearance change post-transplantation. A t-test was run to determine if the rates of Appearance Transfer differed from Appearance Persistence. Average Appearance Transfer rate (2.6%) was significantly lower than Appearance Persistence rate (66%) (P<0.001), indicating that donor's appearance transfer to the recipient is negligible, whereas recipients will be identified the majority of the time. External facial features were important in facial recognition of recipients, evidenced by a significant rise in Appearance Persistence from 19% in the absence of external features to 66% when those features were present (P<0.01). This study may be helpful in the

Protein secondary structure appears to be robust under in silico evolution while protein disorder appears not to be.

KAUST Repository

Schaefer, Christian

2010-01-16

MOTIVATION: The mutation of amino acids often impacts protein function and structure. Mutations without negative effect sustain evolutionary pressure. We study a particular aspect of structural robustness with respect to mutations: regular protein secondary structure and natively unstructured (intrinsically disordered) regions. Is the formation of regular secondary structure an intrinsic feature of amino acid sequences, or is it a feature that is lost upon mutation and is maintained by evolution against the odds? Similarly, is disorder an intrinsic sequence feature or is it difficult to maintain? To tackle these questions, we in silico mutated native protein sequences into random sequence-like ensembles and monitored the change in predicted secondary structure and disorder. RESULTS: We established that by our coarse-grained measures for change, predictions and observations were similar, suggesting that our results were not biased by prediction mistakes. Changes in secondary structure and disorder predictions were linearly proportional to the change in sequence. Surprisingly, neither the content nor the length distribution for the predicted secondary structure changed substantially. Regions with long disorder behaved differently in that significantly fewer such regions were predicted after a few mutation steps. Our findings suggest that the formation of regular secondary structure is an intrinsic feature of random amino acid sequences, while the formation of long-disordered regions is not an intrinsic feature of proteins with disordered regions. Put differently, helices and strands appear to be maintained easily by evolution, whereas maintaining disordered regions appears difficult. Neutral mutations with respect to disorder are therefore very unlikely.

Forensic DNA Phenotyping: Predicting human appearance from crime scene material for investigative purposes.

Science.gov (United States)

Kayser, Manfred

2015-09-01

Forensic DNA Phenotyping refers to the prediction of appearance traits of unknown sample donors, or unknown deceased (missing) persons, directly from biological materials found at the scene. "Biological witness" outcomes of Forensic DNA Phenotyping can provide investigative leads to trace unknown persons, who are unidentifiable with current comparative DNA profiling. This intelligence application of DNA marks a substantially different forensic use of genetic material rather than that of current DNA profiling presented in the courtroom. Currently, group-specific pigmentation traits are already predictable from DNA with reasonably high accuracies, while several other externally visible characteristics are under genetic investigation. Until individual-specific appearance becomes accurately predictable from DNA, conventional DNA profiling needs to be performed subsequent to appearance DNA prediction. Notably, and where Forensic DNA Phenotyping shows great promise, this is on a (much) smaller group of potential suspects, who match the appearance characteristics DNA-predicted from the crime scene stain or from the deceased person's remains. Provided sufficient funding being made available, future research to better understand the genetic basis of human appearance will expectedly lead to a substantially more detailed description of an unknown person's appearance from DNA, delivering increased value for police investigations in criminal and missing person cases involving unknowns.

2012-01-01

Computer graphics systems today are able to produce highly realistic images. The realism has reached a level where an observer has difficulties telling whether an image is real or synthetic. The exception is when we try to compute a picture of a scene that really exists and compare the result...... in the scene have few geometrical details, a graphics system will still have a hard time predicting the result of taking a picture with a digital camera. The problem here is to model the optical properties of the materials correctly. In this chapter, we show how Lorenz–Mie theory enables us to compute...... the optical properties of turbid materials such that we can predict their appearance. To describe the entire process of predicting the appearance of amaterial, we include a description of the mathematical models used in realistic image synthesis....

Gloss as an aspect of the measurement of appearance

Science.gov (United States)

Ji, Wei; Pointer, Mike R.; Luo, Ronnier M.; Dakin, John

2006-01-01

The perception and measurement of gloss is just one part of the concept of appearance measurement. We describe the comparison between data derived by 20 observers who each scaled the perceived gloss of a set of 84 neutral and colored test samples and measurements of those samples made using a glossmeter and a sphere-based spectrophotometer. With a glossmeter, the relationship between the visual-scaled data and the measured gloss values could be described by a three-part linear fit or, with a higher correlation, a cubic function. For the sphere-based spectrophotometer, the difference in the luminance factor, DeltaY, between specular-included and specular-excluded measurements, was found to give a better linear correlation with the observer-scaled data. The color of the samples did not appear to significantly change the perceived gloss of the surface.

Emotion and anxiety potentiate the way attention alters visual appearance.

Science.gov (United States)

Barbot, Antoine; Carrasco, Marisa

2018-04-12

The ability to swiftly detect and prioritize the processing of relevant information around us is critical for the way we interact with our environment. Selective attention is a key mechanism that serves this purpose, improving performance in numerous visual tasks. Reflexively attending to sudden information helps detect impeding threat or danger, a possible reason why emotion modulates the way selective attention affects perception. For instance, the sudden appearance of a fearful face potentiates the effects of exogenous (involuntary, stimulus-driven) attention on performance. Internal states such as trait anxiety can also modulate the impact of attention on early visual processing. However, attention does not only improve performance; it also alters the way visual information appears to us, e.g. by enhancing perceived contrast. Here we show that emotion potentiates the effects of exogenous attention on both performance and perceived contrast. Moreover, we found that trait anxiety mediates these effects, with stronger influences of attention and emotion in anxious observers. Finally, changes in performance and appearance correlated with each other, likely reflecting common attentional modulations. Altogether, our findings show that emotion and anxiety interact with selective attention to truly alter how we see.

CARS detection of liquid-like phase appearance in small mesopores

Science.gov (United States)

Arakcheev, Vladimir G.; Bekin, Alexey N.; Morozov, Viacheslav B.

2017-11-01

Nonlinear-optical spectroscopic techniques that employ signals from the molecules located inside nanopores have promising potential for investigations of fluid behavior under nanoconfinement. Here, we apply coherent anti-Stokes spectroscopy to investigate the appearance of a liquid-like phase of carbon dioxide in mesoporous Vycor glass under isothermal compression. The spectra of the Q-branch (1388 cm-1) are registered at  -11 °C in a wide pressure range, starting from submonolayer coverage of the pore wall up to the bulk saturation pressure. Results show that a spectral contribution, similar to that of the bulk liquid, appears at relatively low pressure that is several times lower than the capillary-condensation pressure. The Raman shift of the peak is equal to that of the bulk liquid, although the linewidth is somewhat increased. The peak is attributed to the layers adsorbed beyond the monolayer or to small liquid-like clusters appearing in specific areas of the porous network. The spectroscopic approach presented here demonstrates the ability to detect and estimate small amounts of the liquid-like phase and to distinguish it from the layers strongly interacting with the pore surface.

ENGLISH ABSTRACT: In this research, a Markov analysis of acceptance sampling plans in a single stage and in two stages is proposed, based on the quality of the items inspected. In a stage of this policy, if the number of defective items in a sample of inspected items is more than the upper threshold, the batch is rejected. However, the batch is accepted if the number of defective items is less than the lower threshold. Nonetheless, when the number of defective items falls between the upper and lower thresholds, the decision-making process continues to inspect the items and collect further samples. The primary objective is to determine the optimal values of the upper and lower thresholds using a Markov process to minimise the total cost associated with a batch acceptance policy. A solution method is presented, along with a numerical demonstration of the application of the proposed methodology.

AFRIKAANSE OPSOMMING: In hierdie navorsing word ’n Markov-ontleding gedoen van aannamemonsternemingsplanne wat plaasvind in ’n enkele stap of in twee stappe na gelang van die kwaliteit van die items wat geïnspekteer word. Indien die eerste monster toon dat die aantal defektiewe items ’n boonste grens oorskry, word die lot afgekeur. Indien die eerste monster toon dat die aantal defektiewe items minder is as ’n onderste grens, word die lot aanvaar. Indien die eerste monster toon dat die aantal defektiewe items in die gebied tussen die boonste en onderste grense lê, word die besluitnemingsproses voortgesit en verdere monsters word geneem. Die primêre doel is om die optimale waardes van die booonste en onderste grense te bepaal deur gebruik te maak van ’n Markov-proses sodat die totale koste verbonde aan die proses geminimiseer kan word. ’n Oplossing word daarna voorgehou tesame met ’n numeriese voorbeeld van die toepassing van die voorgestelde oplossing.

Sclerosing encapsulating peritonitis (SEP) is a serious complication of peritoneal dialysis (PD) characterized by thickened peritoneal membranes, which lead to decreased ultra-filtration and intestinal obstruction. Its early clinical features are nonspecific, and it is often diagnosed late following laparotomy and peritoneal biopsy, when the patient develops small bowel obstruction, which can be a life-threatening complication. However, this is changing with increasing awareness of computed tomography (CT) findings in SEP. CT can yield an early, non-invasive diagnosis that may improve patient outcome.

Milky Way Monster Stars in Cosmic Reality Show

2003-01-01

The longest X-ray look yet at the supermassive black hole at the Milky Way's center has given astronomers unprecedented access to its life and times. The new data from NASA's Chandra X-ray Observatory revealed that our galaxy's central black hole is a frequent bad actor, prone to numerous outbursts and occasional large explosions. The observations of the black hole, a.k.a. Sagittarius A* or Sgr A*, occurred over a two-week period for a total exposure time of 164 hours. During this time Sgr A* flared up in X-ray intensity half a dozen or more times. Astronomers also found evidence that suggests it had an even more boisterous past. These discoveries will help to unlock the secrets of how Sgr A* grows and how it interacts with its environment "We are getting a look at the everyday life of a supermassive black hole like never before," said Frederick K. Baganoff of the Massachusetts Institute of Technology in Cambridge, who presented these new results on behalf of an international team at a press conference today at the American Astronomical Society meeting in Seattle. "We see it flaring on an almost daily basis." Sagittarius A* More images of Sagittarius A* The cause of the flares is not understood, but the rapidity with which they rise and fall indicates that they are occurring near the event horizon, or point of no return, around the black hole. Even when it flares, the intensity of the X-ray emission from the vicinity of the black hole is relatively weak, which suggests that Sgr A*, weighing in at 3 million times the mass of the Sun, is a starved black hole. "Although it appears to snack often, this black hole is definitely on a severe diet," says Baganoff. "This could be because explosive events in the past blew away much of the gas from the neighborhood of the black hole." Indeed, evidence for such events - which astronomers are viewing 26,000 years later due to the time it takes light to travel to Earth from the center of the Galaxy - can be found in the image. A

NOvA Short-Baseline Tau Neutrino Appearance Search

Standard three-flavor neutrino oscillations have well explained by a wide range of neutrino experiments. However, the anomalous results, such as electron-antineutrino excess seen by LSND and MiniBooNE do not fit the three-flavor paradigm. This can be explained by an additional fourth flavor sterile neutrino at a larger scale than the existing three flavor neutrinos. The NOvA experiment consists of two finely segmented, liquid scintillator detectors operating 14 .6 mrad off-axis from the NuMI muon-neutrino beam. The Near Detector is located on the Fermilab campus, 1 km from the NuMI target, while the Far Detector is located at Ash River, MN, 810 km from the NuMI target. The NOvA experiment is primarily designed to measure electron-neutrino appearance at the Far Detector using the Near Detector to control systematic uncertainties; however, the Near Detector is well suited for searching for anomalous short-baseline oscillations. This poster will present a novel method for selecting tau neutrino interactions with high purity at the Near Detector using a convolutional neural network. Using this method, the sensitivity to anomalous short-baseline tau-neutrino appearance due to sterile neutrino oscillations will be presented.

A characteristic phenotypic retinal appearance in Norrie disease.

Drenser, Kimberly A; Fecko, Alice; Dailey, Wendy; Trese, Michael T

2007-02-01

To describe a striking retinal finding that the authors have only seen in Norrie disease eyes and to determine if a particular genotype corresponds to this dramatic presentation. This is a retrospective, interventional case report of four patients seen in the clinic over a 1-year period. All patients had analysis of the Norrie gene by direct sequencing. All patients presented with a similar retinal appearance of dense stalk tissue, globular dystrophic retina, and peripheral avascular retina with pigmentary changes. Each patient was found to have a mutation in the Norrie gene affecting a cystine residue in the cystine knot domain. The mutations are predicted to disrupt the structure of the protein product, norrin, which is required for activation of the Wnt receptor:beta-catenin pathway. No other vitreoretinopathy that the authors have seen demonstrates this characteristic retinal presentation of severe retinal dysplasia. All four patients were found to have mutations in the Norrie gene which alter the cystine knot motif. Mutations affecting this domain appear to have devastating effects on retinal development and indicate phenotype correlates with mutations affecting the cystine knot domain.

Fast and exact Newton and Bidirectional fitting of Active Appearance Models.

Active Appearance Models (AAMs) are generative models of shape and appearance that have proven very attractive for their ability to handle wide changes in illumination, pose and occlusion when trained in the wild, while not requiring large training dataset like regression-based or deep learning methods. The problem of fitting an AAM is usually formulated as a non-linear least squares one and the main way of solving it is a standard Gauss-Newton algorithm. In this paper we extend Active Appearance Models in two ways: we first extend the Gauss-Newton framework by formulating a bidirectional fitting method that deforms both the image and the template to fit a new instance. We then formulate a second order method by deriving an efficient Newton method for AAMs fitting. We derive both methods in a unified framework for two types of Active Appearance Models, holistic and part-based, and additionally show how to exploit the structure in the problem to derive fast yet exact solutions. We perform a thorough evaluation of all algorithms on three challenging and recently annotated inthe- wild datasets, and investigate fitting accuracy, convergence properties and the influence of noise in the initialisation. We compare our proposed methods to other algorithms and show that they yield state-of-the-art results, out-performing other methods while having superior convergence properties.

First impressions based on facial appearance predict many important social outcomes. We investigated whether such impressions also influence the communication of scientific findings to lay audiences, a process that shapes public beliefs, opinion, and policy. First, we investigated the traits that engender interest in a scientist's work, and those that create the impression of a "good scientist" who does high-quality research. Apparent competence and morality were positively related to both interest and quality judgments, whereas attractiveness boosted interest but decreased perceived quality. Next, we had members of the public choose real science news stories to read or watch and found that people were more likely to choose items that were paired with "interesting-looking" scientists, especially when selecting video-based communications. Finally, we had people read real science news items and found that the research was judged to be of higher quality when paired with researchers who look like "good scientists." Our findings offer insights into the social psychology of science, and indicate a source of bias in the dissemination of scientific findings to broader society.

Measurement of electron neutrino appearance with the MINOS experiment

International Nuclear Information System (INIS)

Boehm, Joshua Adam Alpern

2009-01-01

MINOS is a long-baseline two-detector neutrino oscillation experiment that uses a high intensity muon neutrino beam to investigate the phenomena of neutrino oscillations. By measuring the neutrino interactions in a detector near the neutrino source and again 735 km away from the production site, it is possible to probe the parameters governing neutrino oscillation. The majority of the ν μ oscillate to ν τ but a small fraction may oscillate instead to ν e . This thesis presents a measurement of the ν e appearance rate in the MINOS far detector using the first two years of exposure. Methods for constraining the far detector backgrounds using the near detector measurements is discussed and a technique for estimating the uncertainty on the background and signal selection are developed. A 1.6σ excess over the expected background rate is found providing a hint of ν e appearance.

By the progress of computer, computer peripherals such as color monitor and printer are often used to generate color image. However, cross media color reproduction by human perception is usually different. Basically, the influence factors are device calibration and characterization, viewing condition, device gamut and human psychology. In this thesis, a color reproduction system based on color appearance model and gamut mapping is proposed. It consists of four parts; device characterization, color management technique, color appearance model and gamut mapping.

Full Text Available This paper analyzes the internal mechanisms of the individual positive and negative attitude towards appearance, the description of which is under-represented in the psychological literature. The process of creating a consistent image of the physical «Self» and maintaining a positive emotional evaluation of the body and appearance particularly seen through the idea of assigning the individual components of appearance, committed throughout the whole course of life, and is understood as a specific psychological problem, addressable only in human personality as integrative unity, preserving and maintaining its integrity. The hypothesis of the study made by the assumption that a positive attitude to their external appearance is ensured, actualization processes semantic and symbolic mediation of the physical and expressive features, and on the contrary, a negative attitude toward the appearance indicates the failure of such processes. The following characteristics of body image were considered: emotional assessment and the nature of the work on the body, the internal means of maintaining a positive attitude to their appearance, and also the broader context of personal characteristics, particularly the motivational sphere, psychological defenses, the general harmony, integration of personality structure. Differences were demonstrated between conscious and unconscious relation to the external appearance among the subjects, presented significant correlations between the non-integration of personal organization and the negative attitude towards appearance, and between the presence of supervaluation group needs and the negative assessment by the subjects of their appearance. The subjects who accept their appearance are characterized by a greater representation of mediation systems as the assignment of funds in the structure of the physical image «Self», as compared to subjects not receiving their physical appearance.

Describe the imaging appearance of well-differentiated liposarcoma with myxoid stroma (WDLMS) and correlate with histopathology. A keyword search of the institution medical records was performed from 1 January 2000 to 30 June 2017. The histopathology slides of cases identified in this fashion were then reviewed by a pathologist. Additional cases were prospectively collected from extramural referrals and tumor boards. Diagnostic imaging studies of pathologically proven cases of WDLMS were then reviewed in consensus and correlated with pathology. Ten cases of pathologically proven WDLMS were identified (7 men, 3 women, ages 26-81). Tumor location included the retroperitoneum (n = 5), thigh (n = 4), and the shin (n = 1). Nine patients had macroscopic fat on imaging. The nonlipomatous components had a variable appearance, including septal, nodular, and lacelike patterns. Two cases included two distinct areas that were predominantly myxoid or lipomatous ("bi-morphic"). One tumor had no macroscopic fat on imaging. On CT, the nonlipomatous nodular components were hypodense/had hypodense areas. On MRI, the nodular components had intermediate/bright T2W signal. Interval nonlipomatous nodular growth was identified in 3 cases. WDLMS may present on imaging as a mass with variable morphology and amounts of nonlipomatous components. Histopathological diagnosis of WDLMS is challenging and imaging correlation may be helpful, as this tumor may have ≥50% fatty volume, may have a myxoid nodular component or bi-morphic appearance, or may be located in the retroperitoneum, features that are unusual for myxoid liposarcoma. WDLMS with a nodular component cannot be distinguished from dedifferentiated liposarcoma based on imaging alone.

Despite advances in antenatal imaging and genetic techniques, post-delivery post-mortem foetal radiography remains the key investigation in accurate diagnosis of skeletal dysplasia manifesting in the foetus. Foetal radiography is best performed using pathology-specimen radiography equipment and is often carried out in the pathology department without involvement of the radiology unit. However, paediatric radiologists may be asked to interpret post-mortem foetal radiographs when an abnormality is suspected. Many foetal radiographs are carried out before 20 weeks' gestation, and the interpreting radiologist needs to be familiar with the range of normal post-mortem foetal appearances at different gestational ages, as well as the appearances of some of the more commonly presenting skeletal dysplasias, and will benefit from a systematic approach when assessing more challenging cases. In this pictorial essay, we illustrate various normal post-mortem foetal radiographic appearances, give examples of commonly occurring skeletal dysplasias, and describe an approach to establishing more difficult diagnoses.

Mass media, 'monsters' and mental health clients: the need for increased lobbying.

Science.gov (United States)

Cutcliffe, J R; Hannigan, B

2001-08-01

A review of the limited empirical and theoretical literature indicates that current mass media representations of mental health service users appear to emphasize violence, dangerousness and criminality. This is despite the empirical evidence that indicates a decline over the last 40 years in the number of homicides carried out by people identified as suffering from mental health problems. Such inappropriate representations do much to increase stigma, ostracism, harassment and victimization of these individuals by the public. Furthermore, it can be argued that there is another repercussion of these representations and that is the subsequent government position/policy and the resulting legislation concerning care of people with mental health problems. Consequently, this paper argues that there is a clear need for psychiatric/mental health (P/MH) nurses to become more mindful of the wider, socio-political environment in which their practice occurs, particularly if psycho-social approaches to practice are adopted in their fullest sense, and as a result increase their political lobby. Such increased lobbying should occur on behalf of, and in collaboration with, service users, and accordingly the authors describe a range of activities under the broad headings of pro-active and reactive lobbying. Furthermore, it is incumbent upon P/MH nurse educationalists to prepare aspirant P/MH nurses for this lobbying role and equip them with the skills necessary to do so.

Effects Of Combinations Of Patternmaking Methods And Dress Forms On Garment Appearance

Full Text Available We investigated the effects of the combinations of patternmaking methods and dress forms on the appearance of a garment. Six upper garments were made using three patternmaking methods used in France, Italy, and Japan, and two dress forms made in Japan and France. The patterns and the appearances of the garments were compared using geometrical measurements. Sensory evaluations of the differences in garment appearance and fit on each dress form were also carried out. In the patterns, the positions of bust and waist darts were different. The waist dart length, bust dart length, and positions of the bust top were different depending on the patternmaking method, even when the same dress form was used. This was a result of differences in the measurements used and the calculation methods employed for other dimensions. This was because the ideal body shape was different for each patternmaking method. Even for garments produced for the same dress form, the appearances of the shoulder, bust, and waist from the front, side, and back views were different depending on the patternmaking method. As a result of the sensory evaluation, it was also found that the bust and waist shapes of the garments were different depending on the combination of patternmaking method and dress form. Therefore, to obtain a garment with better appearance, it is necessary to understand the effects of the combinations of patternmaking methods and body shapes.

Motives for UV exposure have been shown to be related to appearance concerns, yet little research has examined specific tan appearance attitudes. Given this lacuna, Study 1 involved the identification of six factors among college female tanners: general attractiveness, media influence, family/friends influence, physical fitness appearance, acne reasons, and skin aging concerns. In Study 2, a separate sample of college female tanners were used to validate a higher order factor model, which demonstrated acceptable fit. Additionally, the factors converged in the expected directions, with the general attractiveness and skin aging concerns being the best correlate of UV exposure and sun-protection intentions. The relevance of these findings to skin cancer prevention is discussed.

CT appearance of focal fatty infiltration of the liver

International Nuclear Information System (INIS)

Halvorsen, R.A.; Korobkin, M.; Ram, P.C.; Thompson, W.M.

1982-01-01

Focal fatty infiltration of the liver is an entity that may be confused with liver metastasis on computed tomography (CT). The imaging results and medical records of 16 patients with CT appearance suggestive of focal fatty liver were reviewed, three of whom had the simultaneous presence of metastitic liver disease. Focal fatty liver often has a distinctive appearance with CT, usually with a nonspherical shape, absence of mass effect, and density close to water. Liver metastases are usually round or oval, and unless cystic or necrotic, they have CT attenuation values closer to normal liver parenchyma than water. A radionuclide liver scan almost always resolves any confusion about the differential diagnosis of focal fatty liver: a well defined focus of photon deficiency is due to neoplasm rather than focal fatty infiltration. Sonography sometimes helps to confirm the CT impression, but may be misleading if the diagnosis of focal or diffuse fatty infiltration is not suspected before the examination

2010-08-01

Full Text Available Hepatocellular carcinoma (HCC shows many pathological features, and it varies architecturally and cytologically. There have been many reports and discussions of the morphological features of HCC. A 63-year-old man was found to have a solitary tumor in liver segment 7 that was diagnosed as HCC. A partial resection of liver segment 7 was performed. Microscopically, the tumor lesion showed a moderately differentiated HCC. There was also a lesion with foamy histiocyte-like cells corresponding to the white lesion in the face of the cut tumor. Immunohistochemical staining showed that they were negative for CD68, S-100, vimentin, and HMB-45. The cytoplasm itself was negative on periodic acid Schiff (PAS and Sudan staining. Without immunohistological analysis, it is difficult to distinguish this HCC variant from clear cell carcinoma or metastases of renal cell carcinoma. It is important to recognize this type as a specific cytological variant of HCC that requires confirmation by immunohistochemistry. This report describes the case of a patient with a morphologically distinctive pattern of HCC with prominent cell cytoplasm that had a foamy histiocyte-like appearance. To the best of our knowledge, this is the first report of this HCC variant.

Support vector machine-based facial-expression recognition method combining shape and appearance

Science.gov (United States)

Han, Eun Jung; Kang, Byung Jun; Park, Kang Ryoung; Lee, Sangyoun

2010-11-01

Facial expression recognition can be widely used for various applications, such as emotion-based human-machine interaction, intelligent robot interfaces, face recognition robust to expression variation, etc. Previous studies have been classified as either shape- or appearance-based recognition. The shape-based method has the disadvantage that the individual variance of facial feature points exists irrespective of similar expressions, which can cause a reduction of the recognition accuracy. The appearance-based method has a limitation in that the textural information of the face is very sensitive to variations in illumination. To overcome these problems, a new facial-expression recognition method is proposed, which combines both shape and appearance information, based on the support vector machine (SVM). This research is novel in the following three ways as compared to previous works. First, the facial feature points are automatically detected by using an active appearance model. From these, the shape-based recognition is performed by using the ratios between the facial feature points based on the facial-action coding system. Second, the SVM, which is trained to recognize the same and different expression classes, is proposed to combine two matching scores obtained from the shape- and appearance-based recognitions. Finally, a single SVM is trained to discriminate four different expressions, such as neutral, a smile, anger, and a scream. By determining the expression of the input facial image whose SVM output is at a minimum, the accuracy of the expression recognition is much enhanced. The experimental results showed that the recognition accuracy of the proposed method was better than previous researches and other fusion methods.

1996-01-01

Twelve horses were injected intra-articularly into the metacarpophalangeal joint and extra-articularly in the region of the lateral palmar digital nerve with 1 ml air and local anaesthetic to simulate gas accidentally introduced during regional anaesthesia. Half the horses underwent limited exercise after which all horses were radiographed at 15 and 45 min and then every 24 h until all evidence of gas had disappeared. Intra-articular gas appeared as gas capped radiolucencies (GCR) in the proximal aspect of the joint. Extra-articular gas appeared as linear radiolucencies (LR) which initially tended to migrate proximally. There was no significant difference in gas resorption in exercised and nonexercised horses. All gas was resorbed within 96 h with most of the gas already gone at 48 h

Spontaneous bacterial peritonitis (SBP) as a monomicrobial infection of ascites fluid is one of the most important causes of morbidity and mortality in cirrhotic patients. This study was aimed to determine the diagnostic accuracy of ascites fluid color in detection of SBP in cirrhotic cases referred to the emergency department. Cirrhotic patients referred to the ED for the paracentesis of ascites fluid were enrolled. For all studied patients, the results of laboratory analysis and gross appearance of ascites fluid registered and reviewed by two emergency medicine specialists. The sensitivity, specificity, positive and negative predictive value, and positive and negative likelihood ration of the ascites fluid gross appearance in detection of SBP were measured with 95% confidence interval. The present project was performed in 80 cirrhotic patients with ascites (52.5 female). The mean of the subjects' age was 56.25±12.21 years (35-81). Laboratory findings revealed SBP in 23 (29%) cases. Fifty nine (73%) cases had transparent ascites fluid appearance of whom 17 (29%) ones suffered from SBP. From 21 (26%) cases with opaque ascites appearance, 15 (71%) had SBP. The sensitivity and specificity of the ascites fluid appearance in detection of SBP were 46.88% (Cl: 30.87-63.55) and 87.50% (95% Cl: 75.3-94.14), respectively. It seems that the gross appearance of ascites fluid had poor diagnostic accuracy in detection of SBP and considering its low sensitivity, it could not be used as a good screening tool for this propose.

The appearance of an inflatable penile prosthesis, visualized on a short tau inversion recovery sequence, is reported, in a patient who had magnetic resonance imaging for pelvic pain subsequent to radical cystoprostatectomy for bladder carcinoma. With suppression of adjacent fat signal, the prosthesis is well delineated from adjacent structures. The fluid-containing cylinders of the prosthesis are of very bright signal intensity, with the relief valve assembly of low signal intensity. 5 refs., 2 figs

X-ray Computed Tomography (CT) was used for the first time on the Apollo 11 Lunar Sample number 10057.30, which had been previously maintained by the White House, then transferred back to NASA under the care of Goddard Space Flight Center. Results from this analysis show detailed images of the internal structure of the moon rock, including vesicles (pores), crystal needles, and crystal bundles. These crystals, possibly the common mineral ilmenite, are found in abundance and with random orientation. Future work, in particular a greater understanding of these crystals and their formation, may lead to a more in-depth understanding of the lunar surface evolution and mineral content.

A Research Agenda for Appearance Changes Due to Breast Cancer Treatment

Full Text Available Breast cancer is one of the most prevalent forms of cancer in the US. It is estimated that more than 180,000 American women will be diagnosed with invasive breast cancer in 2008. Fortunately, the survival rate is relatively high and continually increasing due to improved detection techniques and treatment methods. However, maintaining quality of life is a factor often under emphasized for breast cancer survivors. Breast cancer treatments are invasive and can lead to deformation of the breast. Breast reconstruction is important for restoring the survivor’s appearance. However, more work is needed to develop technologies for quantifying surgical outcomes and understanding women’s perceptions of changes in their appearance. A method for objectively measuring breast anatomy is needed in order to help both the breast cancer survivors and their surgeons take expected changes to the survivor’s appearance into account when considering various treatment options. In the future, augmented reality tools could help surgeons reconstruct a survivor’s breasts to match her preferences as much as possible.

Objective: To investigate CT appearances of different types of emphysema and to determine the clinic value for differential diagnosis. Methods: Twenty-three specimens with emphysema selected from 33 autopsy specimens were included in this study. All specimens were inflated and fixed by Heitzman's method, then examined by spiral CT scan. The CT appearances of different types of emphysema in every specimen were analyzed. After the specimens were cut into 10 mm thickness slices, the CT- pathologic correlation was done. Fifteen clinical cases confirmed by pathology or clinical process were all performed spiral CT scan and analyzed, including emphysema-accompanying pneumonia 11 cases, emphysema-accompanying nodule 4 cases. Result: Centriacinar emphysema (CAE)can be seen in 21 of 23 specimens, pancinar emphysema(PAE) can be seen in 5 of 23 specimens, all coexisting with CAE. Distal acinar emphysema(DAE) can be seen in 19 of 23 specimens, irregular emphysema can be seen in 3 of 23 specimens. In all specimens, emphysema can be seen in bilateral lung fields, distributing similarly. Seventeen of 23 eases (17/23) showed no less than two types of emphysema. Fourteen cases of emphysema- accompanying pneumonia (clinic: 11 cases, specimen: 3 cases) showed 'pseudocavity' or 'pseudohoneycombing' (emphysema lesion that had not been filled in the consolidation). Four eases of emphysema-accompanying nodule showed 'pseudopleuralhollow' (wall of DAE or bulla connecting with nodule). Conclusion: The CT manifestations of emphysema, the characteristics of distribution and multi- type of emphysema coexisting can help differentiate cystic air space diseases. The characteristics of complications of emphysema, the 'pseudocavity', 'pseudohoneycombing' and 'pseudopleuralhollow', may be help for differential diagnosis. (authors)

Targets of interest in video acquired from imaging infrared sensors often exhibit profound appearance variations due to a variety of factors, including complex target maneuvers, ego-motion of the sensor platform, background clutter, etc., making it difficult to maintain a reliable detection process and track lock over extended time periods. Two key issues in overcoming this problem are how to represent the target and how to learn its appearance online. In this paper, we adopt a recent appearance model that estimates the pixel intensity histograms as well as the distribution of local standard deviations in both the foreground and background regions for robust target representation. Appearance learning is then cast as an adaptive Kalman filtering problem where the process and measurement noise variances are both unknown. We formulate this problem using both covariance matching and, for the first time in a visual tracking application, the recent autocovariance least-squares (ALS) method. Although convergence of the ALS algorithm is guaranteed only for the case of globally wide sense stationary process and measurement noises, we demonstrate for the first time that the technique can often be applied with great effectiveness under the much weaker assumption of piecewise stationarity. The performance advantages of the ALS method relative to the classical covariance matching are illustrated by means of simulated stationary and nonstationary systems. Against real data, our results show that the ALS-based algorithm outperforms the covariance matching as well as the traditional histogram similarity-based methods, achieving sub-pixel tracking accuracy against the well-known AMCOM closure sequences and the recent SENSIAC automatic target recognition dataset.

To better understand how body image operates within the context of intimate relationships, we investigated women's responses to appearance feedback from an intimate partner. Participants (N=192) imagined receiving feedback from their partner that was either consistent with their own appearance self-view (i.e., self-verifying), more positive (i.e., self-enhancing), or less positive (i.e., devaluing), and then provided their affective and cognitive reactions. As expected, women's perceptions of their own appearance moderated their reactions. Women with more negative self-views felt happier with enhancing feedback, but thought that it meant their partner understood them less well. They also felt less happy when they received verifying feedback, but felt more understood by their partners. Thus, women with body image dissatisfaction may find themselves stuck in the "cognitive-affective crossfire" reacting ambivalently whether their partner enhances their appearance or confirms their negative self-views. Further examination of partners' actual feedback is needed. Copyright © 2012 Elsevier Ltd. All rights reserved.

Quantifying the conspicuousness of objects against particular backgrounds is key to understanding the evolution and adaptive value of animal coloration, and in designing effective camouflage. Quantifying detectability can reveal how colour patterns affect survival, how animals' appearances influence habitat preferences, and how receiver visual systems work. Advances in calibrated digital imaging are enabling the capture of objective visual information, but it remains unclear which methods are best for measuring detectability. Numerous descriptions and models of appearance have been used to infer the detectability of animals, but these models are rarely empirically validated or directly compared to one another. We compared the performance of human 'predators' to a bank of contemporary methods for quantifying the appearance of camouflaged prey. Background matching was assessed using several established methods, including sophisticated feature-based pattern analysis, granularity approaches and a range of luminance and contrast difference measures. Disruptive coloration is a further camouflage strategy where high contrast patterns disrupt they prey's tell-tale outline, making it more difficult to detect. Disruptive camouflage has been studied intensely over the past decade, yet defining and measuring it have proven far more problematic. We assessed how well existing disruptive coloration measures predicted capture times. Additionally, we developed a new method for measuring edge disruption based on an understanding of sensory processing and the way in which false edges are thought to interfere with animal outlines. Our novel measure of disruptive coloration was the best predictor of capture times overall, highlighting the importance of false edges in concealment over and above pattern or luminance matching. The efficacy of our new method for measuring disruptive camouflage together with its biological plausibility and computational efficiency represents a substantial
