    The INhibitor of Growth (ING) family of plant homeodomain (PHD) proteins induce apoptosis and regulate gene expression through stress-inducible binding of phospholipids with subsequent nuclear and nucleolar localization. Relocalization occurs concomitantly with interaction with a subset of nuclear proteins, including PCNA, p53 and several regulators of acetylation such as the p300/CBP and PCAF histone acetyltransferases (HATs), as well as the histone deacetylases HDAC1 and hSir2. These interactions alter the localized state of chromatin compaction, subsequently affecting the expression of subsets of genes, including those associated with the stress response (Hsp70), apoptosis (Bax, MDM2) and cell cycle regulation (p21WAF1, cyclin B) in a cell- and tissue-specific manner. The expression levels and subcellular localization of ING proteins are altered in a significant number of human cancer types, while the expression of ING isoforms changes during cellular aging, suggesting that ING proteins may play a role in linking cellular transformation and replicative senescence. The variety of functions attributed to ING proteins suggest that this tumor suppressor serves to link the disparate processes of cell cycle regulation, cell suicide and cellular aging through epigenetic regulation of gene expression. This review examines recent findings in the ING field with a focus on the functions of protein-protein interactions involving ING family members and the mechanisms by which these interactions facilitate the various roles that ING proteins play in tumorigenesis, apoptosis and senescence.

    As computing power gets better and better, computer codes that use a deterministic method seem to be less useful than those using the Monte Carlo method. In addition, users do not like to think about space, angles, and energy discretization for deterministic codes. However, a deterministic method is still powerful in that we can obtain a solution of the flux throughout the problem, particularly as when particles can barely penetrate, such as in a deep penetration problem with small detection volumes. Recently, a new state-of-the-art discrete-ordinates code, ATTILA, was developed and has been widely used in several applications. ATTILA provides the capabilities to solve geometrically complex 3-D transport problems by using an unstructured tetrahedral mesh. Since 2009, we have been developing our own code by benchmarking ATTILA. AETIUS is a discrete ordinates code that uses an unstructured tetrahedral mesh such as ATTILA. For pre- and post- processing, Gmsh is used to generate an unstructured tetrahedral mesh by importing a CAD file (*.step) and visualizing the calculation results of AETIUS. Using a CAD tool, the geometry can be modeled very easily. In this paper, we describe a brief overview of AETIUS and provide numerical results from both AETIUS and a Monte Carlo code, MCNP5, in a deep penetration problem with small detection volumes. The results demonstrate the effectiveness and efficiency of AETIUS for such calculations.

    2005-01-01

    From molecular dynamics simulations of a dipalmitoyl-phosphatidyl-choline (DPPC) lipid bilayer in the liquid crystalline phase, pressure profiles through the bilayer are calculated by different methods. These profiles allow us to address two central and unresolved problems in pressure profile...... calculations: The first problem is that the pressure profile is not uniquely defined since the expression for the local pressure involves an arbitrary choice of an integration contour. We have investigated two different choices leading to the Irving-Kirkwood (IK) and Harasima (H) expressions for the local...... pressure tensor. For these choices we find that the pressure profile is almost independent of the contour used, which indicates that the local pressure is well defined for a DPPC bilayer in the liquid crystalline phase. This may not be the case for other systems and we therefore suggest that both the IK...

    Evolution of ING from initial concept to advanced systems and the interplay between participating disciplines are illustrated in Fig. 1.2. Anticipated requirements for intense continuous fluxes of thermal neutrons set the initial goal and dictated the scale and other guidelines of the system including the desired completion date. While neutron applications were given prime consideration in conceptual planning, much wider fields of research, both pure and applied, would benefit from the facility now being studied. (author)

    Full Text Available Introduction: To identify the differences in a socioeconomic profile between two cohorts of diabetic patients – one with diabetic foot problems and another without diabetic foot problems. Materials and methods: The cohort with diabetic foot problems (including cellulitis, abscess, osteomyelitis, septic arthritis, gangrene, ulcers, or Charcot joint disease consisted of 122 diabetic patients, while the other cohort without foot problems consisted of 112 diabetic patients. Both were seen at the National University Hospital from January to April 2007. A detailed protocol was designed and the factors studied included patient profile, average monthly household income, education, compliance to diabetic medication, attendance at clinics for diabetic treatment, exercise, smoking, alcohol consumption, gender, and glycosylated haemoglobin (HbA1C level. These were studied for significant differences using univariate and stepwise multivariate logistic regression analysis. Results: With multivariate analysis, Malay ethnicity (p<0.001, education of up to secondary school only (p=0.021, low average monthly household income of less than SGD $2,000 (p=0.030, lack of exercise (at least once a week, p=0.04, and elevated HbA1C level (>7.0%; p=0.015 were found to be significantly higher in the cohort with diabetic foot problems than the cohort without. Conclusions: There are significant differences in the socioeconomic factors between diabetic patients with diabetic foot problems and those without.

    The five human ING genes encode at least 15 splicing isoforms, most of which affect cell growth, differentiation and apoptosis through their ability to alter gene expression by epigenetic mechanisms. Since their discovery in 1996, ING proteins have been classified as type II tumour suppressors on the basis of reports describing their down-regulation and mislocalization in a variety of cancer types. In addition to their regulation by transcriptional mechanisms, understanding the range of PTMs (post-translational modifications) of INGs is important in understanding how ING functions are fine-tuned in the physiological setting and how they add to the repertoire of activities affected by the INGs. In the present paper we review the different PTMs that have been reported to occur on INGs. We discuss the PTMs that modulate ING function under normal conditions and in response to a variety of stresses. We also describe the ING PTMs that have been identified by several unbiased MS-based PTM enrichment techniques and subsequent proteomic analysis. Among the ING PTMs identified to date, a subset has been characterized for their biological significance and have been shown to affect processes including subcellular localization, interaction with enzymatic complexes and ING protein half-life. The present review aims to highlight the emerging role of PTMs in regulating ING function and to suggest additional pathways and functions where PTMs may effect ING function.

  17. The ING tumor suppressors in cellular senescence and chromatin

    Directory of Open Access Journals (Sweden)

    2011-07-01

    Full Text Available Abstract The Inhibitor of Growth (ING proteins represent a type II tumor suppressor family comprising five conserved genes, ING1 to ING5. While ING1, ING2 and ING3 proteins are stable components of the mSIN3a-HDAC complexes, the association of ING1, ING4 and ING5 with HAT protein complexes was also reported. Among these the ING1 and ING2 have been analyzed more deeply. Similar to other tumor suppressor factors the ING proteins are also involved in many cellular pathways linked to cancer and cell proliferation such as cell cycle regulation, cellular senescence, DNA repair, apoptosis, inhibition of angiogenesis and modulation of chromatin. A common structural feature of ING factors is the conserved plant homeodomain (PHD, which can bind directly to the histone mark trimethylated lysine of histone H3 (H3K4me3. PHD mutants lose the ability to undergo cellular senescence linking chromatin mark recognition with cellular senescence. ING1 and ING2 are localized in the cell nucleus and associated with chromatin modifying enzymes, linking tumor suppression directly to chromatin regulation. In line with this, the expression of ING1 in tumors is aberrant or identified point mutations are mostly localized in the PHD finger and affect histone binding. Interestingly, ING1 protein levels increase in replicative senescent cells, latter representing an efficient pathway to inhibit cancer proliferation. In association with this, suppression of p33ING1 expression prolongs replicative life span and is also sufficient to bypass oncogene-induced senescence. Recent analyses of ING1- and ING2-deficient mice confirm a tumor suppressive role of ING1 and ING2 and also indicate an essential role of ING2 in meiosis. Here we summarize the activity of ING1 and ING2 as tumor suppressors, chromatin factors and in development.

  19. Multiple ING1 and ING2 genes in Xenopus laevis and evidence for differential association of thyroid hormone receptors and ING proteins to their promoters.

    2008-03-01

    ING (INhibitor of Growth) tumor suppressor proteins are epigenetic factors involved in numerous cellular processes including apoptosis in species ranging from yeast to humans. We recently isolated ING1 and ING2 transcript variants in Xenopus laevis and showed that these transcripts were differentially regulated by thyroid hormone (TH) during postembryonic development. However, no information exists regarding ING gene structure and how it relates to these differential responses to TH. To further investigate the regulation of ING genes by TH, we isolated ING1 and ING2 gene sequences and demonstrated that there are at least duplicate genes for each. The relationship between transcript variants and their responsiveness to TH were examined through promoter sequence and chromatin immunoprecipitation analyses on tail homogenates. Both TH receptors (TRs) differentially associated with ING1 and ING2 promoter regions with increased recruitment in the presence of TH. This occurred irrespective of gene transcript level response to this hormone. However, differential recruitment of RNA polymerase II corresponded well to transcript levels. ING proteins consistently associated with their own gene promoters except in the region generating the TH-inducible xING1b5 transcript. In this case, a substantial recruitment of TRbeta in the absence ING proteins occurred. These data establish the TH-dependent recruitment of transcription factors to ING promoter regions and suggest that differential TR recruitment in response to TH may not be a sufficient indicator for modulating the expression of ING in the tail.

  20. Immediate relation of ING to fast breeder reactor programs

    Lewis, W.B

    1969-07-01

    The future large-scale use of nuclear energy is linked in the United States and other major countries to their fast breeder reactor development. Very serious basic problems have been discovered within the last two years, limiting the life in the high fast neutron flux at appropriate temperatures of materials, in particular of metals suitable for fuel cladding in sodium coolant. There is therefore a most urgent need for materials testing facilities under controlled conditions of temperature and neutron flux at sufficiently high ratings to match or surpass those required in commercially competitive fast breeder reactors. None of the test facilities yet planned for 1976 or sooner in the western world appears to match these conditions. The problem is mainly the difficulty of providing the high neutron flux effectively continuously. The spallation reaction in heavy elements was chosen as the basis of ING - the intense neutron generator, because it is the only known reaction that promises a fast neutron source density that is higher than can be controlled from the fission process. It is suggested that several countries will wish to consider urgently whether they should also explore the spallation reaction for the purpose of a fast neutron irradiation test facility. In view of the discontinuance of the ING project in Canada a favourable opportunity will exist over the next few months 10 obtain from Canada by direct personal contact details of the significant study that has been carried on for ING over the last five years. In the event that satisfactory materials are established within the lifetime of the spallation facilities they may continue to be used for the production of selected isotopes more profitably produced in high neutron fluxes. The facilities may be also used for the desirable preirradiation of thorium reactor fuel. The other research purposes planned for ING could also be served. (author)

    2016-01-01

    This essay aims to show that the concept of ambivalence could prove especially productive for gerontology. It is known that age(ing) is a category that is characterized by difference and at the same time delineates a process. Ambivalence is eminently suitable for capturing this duality as it enables us to take into account the dynamics peculiar to age(ing) and move beyond those conventional rigid distinctions which fail to grasp key nuances. These theoretical considerations will be put to the test by looking at the so-called young-old and their ambivalent positioning as well as their own mimicry of the middle-agers.

    The present paper discusses results of full-scale experimental and numerical investigations of influence of construction materials of portable pulsed neutron generators ING-031, ING-07, ING-06 and ING-10-20-120 (VNIIA, Russia) to their radiation characteristics formed during and after an operation (shutdown period). In particular, it is shown that an original monoenergetic isotropic angular distribution of neutrons emitted by TiT target changes into the significantly anisotropic angular distribution with a broad energy spectrum stretching to the thermal region. Along with the low-energetic neutron part, a significant amount of photons appears during the operation of generators. In the pulse mode of operation of neutron generator, a presence of the construction materials leads to the "tailing" of the original neutron pulse and the appearance of an accompanying photon pulse at ~ 3 ns after the instant neutron pulse. In addition to that, reactions of neutron capture and inelastic scattering lead to the creation of radioactive nuclides, such as 58Co, 62Cu, 64Cu and 18F, which form the so-called activation radiation. Thus, the selection of a portable neutron generator for a particular type of application has to be done considering radiation characteristics of the generator itself. This paper will be of interest to users of neutron generators, providing them with valuable information about limitations of a specific generator and with recommendations for improving the design and performance of the generator as a whole.

    2011-01-01

    The Inhibitor of Growth (ING) proteins belong to a well-conserved family which presents in diverse organisms with several structural and functional domains for each protein. The ING family members are found in association with many cellular processes. Thus, the ING family proteins are involved in regulation of gene transcription, DNA repair, tumorigenesis, apoptosis, cellular senescence and cell cycle arrest. The ING proteins have multiple domains that are potentially capable of binding to many partners. It is conceivable, therefore, that such proteins could function similarly within protein complexes. In this case, within this family, each function could be attributed to a specific domain. However, the role of ING domains is not definitively clear. In this review, we summarize recent advances in structure-function relationships in ING proteins. For each domain, we describe the known biological functions and the approaches utilized to identify the functions associated with ING proteins.

    Children's sleep problems and self-regulation problems have been independently associated with poorer adjustment to school, but there has been limited exploration of longitudinal early childhood profiles that include both indicators. This study explores the normative developmental pathway for sleep problems and self-regulation across early childhood and investigates whether departure from the normative pathway is associated with later social-emotional adjustment to school. This study involved 2,880 children participating in the Growing Up in Australia: The Longitudinal Study of Australian Children (LSAC) - Infant Cohort from Wave 1 (0-1 years) to Wave 4 (6-7 years). Mothers reported on children's sleep problems, emotional, and attentional self-regulation at three time points from birth to 5 years. Teachers reported on children's social-emotional adjustment to school at 6-7 years. Latent profile analysis was used to establish person-centred longitudinal profiles. Three profiles were found. The normative profile (69%) had consistently average or higher emotional and attentional regulation scores and sleep problems that steadily reduced from birth to 5 years. The remaining 31% of children were members of two non-normative self-regulation profiles, both characterized by escalating sleep problems across early childhood and below mean self-regulation. Non-normative group membership was associated with higher teacher-reported hyperactivity and emotional problems, and poorer classroom self-regulation and prosocial skills. Early childhood profiles of self-regulation that include sleep problems offer a way to identify children at risk of poor school adjustment. Children with escalating early childhood sleep problems should be considered an important target group for school transition interventions. © 2016 The British Psychological Society.

  16. Dissociative disorders in children: behavioral profiles and problems.

    Science.gov (United States)

    Putnam, F W

    1993-01-01

    Transient dissociative episodes are a common and normative phenomenon during childhood that generally decrease during adolescence to relatively low levels in adults. Retrospective clinical research has firmly established a connection between childhood trauma and the development of dissociative disorders in adults. A growing number of clinicians are now identifying dissociative symptoms in abused children, and there is increasing evidence that dissociative disorders represent a significant and hitherto unrecognized form of psychopathology in traumatized children. Pathological dissociation is a complex psychobiological process that results in a failure to integrate information into the normal stream of consciousness. It produces a range of symptoms and behaviors including: (a) amnesias; (b) disturbances in sense of self; (c) trance-like states; (d) rapid shifts in mood and behavior; (e) perplexing shifts in access to knowledge, memory, and skills; (f) auditory and visual hallucinations; and (g) vivid imaginary companionship in children and adolescents. Many of these symptoms and behaviors are misdiagnosed as attention, learning or conduct problems, or even psychoses. Early identification and therapeutic intervention appear to be particularly efficacious in children in contrast to adults, although systematic studies of treatment and outcome are presently lacking.

    Ren, Xiaofeng; Wei, Juncheng

    2017-08-01

    The profile problem for the Ohta-Kawasaki diblock copolymer theory is a geometric variational problem. The energy functional is defined on sets in R3 of prescribed volume and the energy of an admissible set is its perimeter plus a long range interaction term related to the Newtonian potential of the set. This problem admits a solution, called a torus profile, that is a set enclosed by an approximate torus of the major radius 1 and the minor radius q. The torus profile is both axially symmetric about the z axis and reflexively symmetric about the xy-plane. There is a way to set up the profile problem in a function space as a partial differential-integro equation. The linearized operator L of the problem at the torus profile is decomposed into a family of linear ordinary differential-integro operators Lm where the index m = 0 , 1 , 2 , … is called a mode. The spectrum of L is the union of the spectra of the Lm's. It is proved that for each m, when q is sufficiently small, Lm is positive definite. (0 is an eigenvalue for both L0 and L1, due to the translation and rotation invariance.) As q tends to 0, more and more Lm's become positive definite. However no matter how small q is, there is always a mode m of which Lm has a negative eigenvalue. This mode grows to infinity like q - 3 / 4 as q → 0.

  1. Integration based profile likelihood calculation for PDE constrained parameter estimation problems

    Science.gov (United States)

    Boiger, R.; Hasenauer, J.; Hroß, S.; Kaltenbacher, B.

    2016-12-01

    Partial differential equation (PDE) models are widely used in engineering and natural sciences to describe spatio-temporal processes. The parameters of the considered processes are often unknown and have to be estimated from experimental data. Due to partial observations and measurement noise, these parameter estimates are subject to uncertainty. This uncertainty can be assessed using profile likelihoods, a reliable but computationally intensive approach. In this paper, we present the integration based approach for the profile likelihood calculation developed by (Chen and Jennrich 2002 J. Comput. Graph. Stat. 11 714-32) and adapt it to inverse problems with PDE constraints. While existing methods for profile likelihood calculation in parameter estimation problems with PDE constraints rely on repeated optimization, the proposed approach exploits a dynamical system evolving along the likelihood profile. We derive the dynamical system for the unreduced estimation problem, prove convergence and study the properties of the integration based approach for the PDE case. To evaluate the proposed method, we compare it with state-of-the-art algorithms for a simple reaction-diffusion model for a cellular patterning process. We observe a good accuracy of the method as well as a significant speed up as compared to established methods. Integration based profile calculation facilitates rigorous uncertainty analysis for computationally demanding parameter estimation problems with PDE constraints.

    Guérillon, Claire; Bigot, Nicolas; Pedeux, Rémy

    2014-04-01

    ING genes (ING1-5) were identified has tumor suppressor genes. ING proteins are characterized as Type II TSGs since they are involved in the control of cell proliferation, apoptosis and senescence. They may also function as Type I TSGs since they are also involved in DNA replication and repair. Most studies have reported that they are frequently lost in human tumors and epigenetic mechanisms or misregulation of their transcription may be involved. Recently, studies have described that this loss may be caused by microRNA inhibition. Here, we summarize the current knowledge on ING functions, their involvement in tumor suppression and, in order to give a full assessment of the current knowledge, we review all the studies that have examined ING status in human cancers.

  4. Predictors and Consequences of Aggressive–Withdrawn Problem Profiles in Early Grade School

    Science.gov (United States)

    Farmer, Alvin D.; Bierman, Karen L.

    2009-01-01

    Identified first-grade children who exhibited 4 different behavior problem profiles from an initial sample of 754: aggressive–withdrawn (n = 63, 8%) aggressive only (n = 165, 22%), withdrawn only (n = 94, 12%), and nonproblem (n = 432, 57%). Group comparisons revealed that children who became aggressive–withdrawn in first grade exhibited deficits in attention and social skills in kindergarten. Furthermore, these kindergarten deficits contributed to the emergence of their aggressive–withdrawn behavior problems in first grade, after accounting for kindergarten levels of aggressive and withdrawn behaviors. In later grades, aggressive–withdrawn first-grade children were more likely than children in any other group to demonstrate poor peer relations and poor academic performance. In addition, kindergarten skill deficits added to first-grade aggressive and withdrawn behavior problems to predict third-grade social and academic adjustment difficulties. The results document the key role of early inattention and social skill deficits in the prediction of aggressive–withdrawn problem profiles, validate the significance of this problem profile at school entry, and identify potential developmental mechanisms that have implications for preventive interventions.

    2014-07-01

    For more than a decade, the ING studentship programme has offered European astronomy students an opportunity to train as observers on a medium-sized ground-based optical telescope, namely the renowned 2.5-m Isaac Newton Telescope (INT) run by the Isaac Newton Group (ING, a UK-SP-NL institution) on the beautiful Spanish island of La Palma in the Canary Islands! Practical training of the European students and hopefully future astronomers is essential in the era of very large telescopes and their queue-scheduled observing, which limits direct access to the observatories by young astronomers. Each year, the ING therefore offers 4--5 talented astronomy students the opportunity to spend one year working as support astronomers at the INT (setting up the instruments, helping visiting observers, and observing few INT discretionary nights) and working with ING staff on technical and science projects. High above the clouds at 2400 m, on the edge of the gorgeous Caldera de Taburiente of La Palma, stands the ''Roque de Los Muchachos'' Observatory (ORM) of the Instituto de Astrofísica de Canarias (IAC), part of the European Northern Observatory (ENO). Year after year, our studentship programme contributes to a better prepared future generation of astronomers. In this poster, we present some recent technical and science achievements of our past ING students, encouraging talented students to apply in the future (announced in February--March via the ING website http://www.ing.iac.es/astronomy/science/studentship.html).

    2013-12-01

    Full Text Available In the manufacturing process of semiconductors, plasma processing is an essential technology, and the plasma used in the process is required to be of high density, low temperature, large diameter, and high uniformity. This research focuses on the microwave-excited plasma that meets these needs, and the research target is a spatial profile control. Two novel techniques are introduced to control the uniformity; one is a segmented slot antenna that can change radial distribution of the radiated field during operation, and the other is a hyper simulator that can predict microwave power distribution necessary for a desired radial density profile. The control system including these techniques provides a method of controlling radial profiles of the microwave plasma via inverse-problem approach, and is investigated numerically and experimentally.

    Helland, Wenche Andersen; Helland, Turid; Heimann, Mikael

    2014-04-01

    This study aimed to explore whether children with specific language impairment (SLI) and children with ADHD can be differentiated from each other in terms of their language profiles, and also to investigate whether these two clinical groups differ regarding mental health problems. A total of 59 children in the age range 6 to 12 years participated in the study. The parents completed the Children's Communication Checklist-Second Edition and the Strengths and Difficulties Questionnaire. Communication impairments were as prominent in the ADHD group as in the SLI group; however, the groups were separable from each other in terms of their language profiles. Furthermore, the ADHD group experienced significantly more mental health problems compared with the SLI group. Language should be assessed in children with ADHD and instruments sensitive to ADHD should be included when assessing children with SLI. Mental health should be an area of concern to be addressed in both groups.

    Full Text Available This work describes the restraints in the optimization problem. This is an important and complicated issue because it requires taking into account a vast range of information related to the design and production. In order to describe the relations of a specific optimization problem, it is essential to adopt appropriate criteria and to collect information on all kinds of restraints, i.e. boundary conditions. The following paper verifies the various restraints and defines three subsets: design assumptions, technological limitations and standard conditions. The provided classification was made with reference to the analysis of the construction applicability of the newly patented cold-formed profile.

    2014-08-19

    Cancer cells accumulate genetic and epigenetic changes that alter gene expression to drive tumorigenesis. Epigenetic silencing of tumor suppressor, cell cycle, differentiation and DNA repair genes contributes to neoplastic transformation. The ING (inhibitor of growth) proteins (ING1-ING5) have emerged as a versatile family of growth regulators, phospholipid effectors, histone mark sensors and core components of HDAC1/2 - and several HAT chromatin-modifying complexes. This review will describe the characteristic pathways by which ING family proteins differentially affect the Hallmarks of Cancer and highlight the various epigenetic mechanisms by which they regulate gene expression. Finally, we will discuss their potentials as biomarkers and therapeutic targets in epigenetic treatment strategies. Copyright © 2014 Federation of European Biochemical Societies.

    Dans le contexte d'une nouvelle mission au CNDP, le concept d'ingénierie éducative ne se pense nullement comme une nouvelle théorie de l'apprentissage qui viendrait prendre le relais du Behaviorisme ou de la Psychologie cognitive. L'ingénierie éducative relève d'une approche pragmatique, à l'image de celle de l'ingénieur. En pensant les technologies dans leur contexte, l'ingénierie éducative les prend, en quelque sorte, au sérieux, c'est-à-dire dans l'exacte limite de leur fonction.

  15. The performance profile: A multi–criteria performance evaluation method for test–based problems

    Directory of Open Access Journals (Sweden)

    Jaśkowski Wojciech

    2016-03-01

    Full Text Available In test-based problems, solutions produced by search algorithms are typically assessed using average outcomes of interactions with multiple tests. This aggregation leads to information loss, which can render different solutions apparently indifferent and hinder comparison of search algorithms. In this paper we introduce the performance profile, a generic, domain-independent, multi-criteria performance evaluation method that mitigates this problem by characterizing the performance of a solution by a vector of outcomes of interactions with tests of various difficulty. To demonstrate the usefulness of this gauge, we employ it to analyze the behavior of Othello and Iterated Prisoner’s Dilemma players produced by five (coevolutionary algorithms as well as players known from previous publications. Performance profiles reveal interesting differences between the players, which escape the attention of the scalar performance measure of the expected utility. In particular, they allow us to observe that evolution with random sampling produces players coping well against the mediocre opponents, while the coevolutionary and temporal difference learning strategies play better against the high-grade opponents. We postulate that performance profiles improve our understanding of characteristics of search algorithms applied to arbitrary test-based problems, and can prospectively help design better methods for interactive domains.

  17. Signaling pathways of the ING proteins in apoptosis.

    Science.gov (United States)

    Shah, Sitar; Riabowol, Karl

    2009-05-01

    Members of the ING family of type II tumor suppressors reside in different chromatin regulatory complexes and are stoichiometeric members of histone acetyltransferase (HAT) and histone deacetylase (HDAC) complexes. It has been frequently observed that expressing ING proteins promotes apoptosis in both normal and transformed cells of different species. They have also been reported to either rely upon p53, or to add to its ability to promote programmed cell death (apoptosis) although whether ING proteins require p53 to induce apoptosis is now questionable based upon observations using knockout cell lines and animal models. Genetic studies in model organisms, and particularly in Caenorhabditis elegans, have identified different pathways involved in apoptosis during development, in the germ line and in response to various forms of stress including DNA damage. In this review we summarize structural features of the INGs and recent observations made in knockout models of Mus musculus and Caenorhabditis elegans that have helped to further clarify the functions of the ING proteins in biochemical pathways leading to apoptosis. Based upon these observations we propose a model for how ING proteins may act both independently and in concert with p53 to promote apoptosis.

    UK social firms are under-researched but are a potentially important vocational option for people with mental health problems. To describe the clinical profile, satisfaction levels and experiences of social firms employees with mental health problems. Clinical, work and service use characteristics were collected from social firms' employees with mental health problems in England and Wales. Workplace experience and satisfaction were explored qualitatively. Predominantly, social firms' employees (N = 80) report that they have a diagnosis of depression (56%) and anxiety (41%). People with schizophrenia (20%) or bipolar disorder (5%) were a minority. Respondents had low symptom and disability levels, high quality of life and job satisfaction and experienced reductions in secondary mental health service use over time. High-workplace satisfaction was related to flexibility, manager and colleague support and workplace accommodations. The clinical profile, quality of life and job satisfaction level of employees with mental health problems suggest social firms could be a useful addition to UK vocational services for some people. Current employees mainly have common mental disorders, and social firms will need to shift their focus if they are to form a substantial pathway for the vocational recovery of people currently using community mental health teams.

    2014-01-01

    Three cohorts of third-grade students (N = 813) were evaluated on achievement, cognitive abilities, and behavioral attention according to contrasting research traditions in defining math learning disability (LD) status: low achievement versus extremely low achievement and IQ-achievement discrepant versus strictly low-achieving LD. We use methods from these two traditions to form math problem solving LD groups. To evaluate group differences, we used MANOVA-based profile and canonical analyses to control for relations among the outcomes and regression to control for group definition variables. Results suggest that basic arithmetic is the key distinguishing characteristic that separates low-achieving problem solvers (including LD, regardless of definition) from typically achieving students. Word problem solving is the key distinguishing characteristic that separates IQ-achievement-discrepant from strictly low-achieving LD students, favoring the IQ-achievement-discrepant students.

    Refraction is a mental activity experienced by a person to make a decision through reflective thinking and critical thinking. Differences in mathematical capability have an influence on the difference of student’s refractive thinking processes in solving math problems. This descriptive research aims to generate a picture of refractive thinking of students in solving mathematical problems in terms of students’ math skill. Subjects in this study consisted of three students, namely students with high, medium, and low math skills based on mathematics capability test. Data collection methods used are test-based methods and interviews. After collected data is analyzed through three stages that are, condensing and displaying data, data display, and drawing and verifying conclusion. Results showed refractive thinking profiles of three subjects is different. This difference occurs at the planning and execution stage of the problem. This difference is influenced by mathematical capability and experience of each subject.

  3. Structural insight into histone recognition by the ING PHD fingers.

    Champagne, Karen S; Kutateladze, Tatiana G

    2009-05-01

    The Inhibitor of Growth (ING) tumor suppressors are implicated in oncogenesis, control of DNA damage repair, cellular senescence and apoptosis. All members of the ING family contain unique amino-terminal regions and a carboxy-terminal plant homeodomain (PHD) finger. While the amino-terminal domains associate with a number of protein effectors including distinct components of histone deacetylase (HDAC) and histone acetyltransferase (HAT) complexes, the PHD finger binds strongly and specifically to histone H3 trimethylated at lysine 4 (H3K4me3). In this review we describe the molecular mechanism of H3K4me3 recognition by the ING1-5 PHD fingers, analyze the determinants of the histone specificity and compare the biological activities and structures within subsets of PHD fingers. The atomic-resolution structures of the ING PHD fingers in complex with a H3K4me3 peptide reveal that the histone tail is bound in a large and deep binding site encompassing nearly one-third of the protein surface. An extensive network of intermolecular hydrogen bonds, hydrophobic and cation-pi contacts, and complementary surface interactions coordinate the first six residues of the H3K4me3 peptide. The trimethylated Lys4 occupies an elongated groove, formed by the highly conserved aromatic and hydrophobic residues of the PHD finger, whereas the adjacent groove accommodates Arg2. The two grooves are connected by a narrow channel, the small size of which defines the PHD finger's specificity, excluding interactions with other modified histone peptides. Binding of the ING PHD fingers to H3K4me3 plays a critical role in regulating chromatin acetylation. The ING proteins function as tethering molecules that physically link the HDAC and HAT enzymatic complexes to chromatin. In this review we also highlight progress recently made in understanding the molecular basis underlying biological and tumorigenic activities of the ING tumor suppressors.

    The study was designed to discover examine the profile of metacognition of vocational high school student of the Machine Technology program that had high ability and field independent cognitive style in mathematical problem solving. The design of this study was exploratory research with a qualitative approach. This research was conducted at the Machine Technology program of the vocational senior high school. The result revealed that the high-ability student with field independent cognitive style conducted metacognition practices well. That involved the three types of metacognition activities, consisting of planning, monitoring, and evaluating at metacognition level 2 or aware use, 3 or strategic use, 4 or reflective use in mathematical problem solving. The applicability of the metacognition practices conducted by the subject was never at metacognition level 1 or tacit use. This indicated that the participant were already aware, capable of choosing strategies, and able to reflect on their own thinking before, after, or during the process at the time of solving mathematical problems.That was very necessary for the vocational high school student of Machine Technology program.

    Full Text Available Different math indices can be used to assess math potential at school entry. We evaluated whether standardized math achievement (TEMA-2 performance, core number abilities (dot enumeration, symbolic magnitude comparison, non-verbal intelligence (NVIQ and visuo-spatial working memory (VSWM, in combination or separately, predicted mental addition problem solving speed over time. We assessed 267 children’s TEMA-2, magnitude comparison, dot enumeration, and VSWM abilities at school entry (5 years and NVIQ at 8 years. Mental addition problem solving speed was assessed at 6, 8, and 10 years. Longitudinal path analysis supported a model in which dot enumeration performance ability profiles and previous mental addition speed predicted future mental addition speed on all occasions, supporting a componential account of math ability. Standardized math achievement and NVIQ predicted mental addition speed at specific time points, while VSWM and symbolic magnitude comparison did not contribute unique variance to the model. The implications of using standardized math achievement and dot enumeration ability to index math learning potential at school entry are discussed.

    The discovery of ING1 gene paved the way to the identification of other ING members (ING2-5) and their isoforms associated with cell cycle, apoptosis and senescence. The ING family has been an emerging putative tumor suppressor gene (TSG) in which the major mechanism is through interaction with the determinants of chromatin function and gene-specific transcription factors. The regulatory mechanism highly involves the conserved plant homeodomain (PHD), which binds to histones in a methylation-sensitive manner, suggesting that ING proteins may contribute to the maintenance of the epigenetic code. Furthermore, ING family members contain nuclear localization signals and N-terminal sequences important in the interaction with histone acetyltransferase (HAT) and histone deacetyltransferase (HDAC) that regulate gene promoter activity within chromatin. Although ING proteins have the same PHD motif, the variation in the N-terminal dictates the differences in tumor the suppressive ability of ING in various tumors. Inactivation of the normal function is achieved through allelic loss of genomic regions containing the ING gene, alteration in the ING promoter region, variation of mRNA splicing efficacy or reduced mRNA stability. It is most probably the apparent combination of these aberrant mechanisms that resulted in reduced availability of functional ING protein. In cancer cells, ING transcript levels are often suppressed but the genes are rarely mutated. The mechanism of suppression of ING expression may have to do with the abnormally high methylation levels of the ING gene promoter, which have been correlated with low transcript levels. Emerging evidence on the function of ING and related regulatory mechanisms strongly points to ING as a candidate TSG and therefore a potential target in the molecular therapy of some types of tumor.

    Poker playing and responsible gambling both entail the use of the executive functions (EF), which are higher-level cognitive abilities. This study investigated if online poker players of different ability showed different performances in their EF and if so, which functions were the most discriminating for their playing ability. Furthermore, it assessed if the EF performance was correlated to the quality of gambling, according to self-reported questionnaires (PGSI, SOGS, GRCS). Three poker experts evaluated anonymized poker hand history files and, then, a trained professional administered an extensive neuropsychological test battery. Data analysis determined which variables of the tests correlated with poker ability and gambling quality scores. The highest correlations between EF test results and poker ability and between EF test results and gambling quality assessment showed that mostly different clusters of executive functions characterize the profile of the strong(er) poker player and those ones of the problem gamblers (PGSI and SOGS) and the one of the cognitions related to gambling (GRCS). Taking into consideration only the variables overlapping between PGSI and SOGS, we found some key predictive factors for a more risky and harmful online poker playing: a lower performance in the emotional intelligence competences (Emotional Quotient inventory Short) and, in particular, those grouped in the Intrapersonal scale (emotional self-awareness, assertiveness, self-regard, independence and self-actualization).

Here, we find a small ubiquitin-like modification (SUMOylation) of the ING1b protein and identify lysine 193 (K193) as the preferred ING1b SUMO acceptor site. We also show that PIAS4 is the E3 SUMO ligase responsible for ING1b...... SUMOylation on K193. Sequence alignment reveals that the SUMO consensus site on ING1b contains a phosphorylation-dependent SUMOylation motif (PDSM) and our data indicate that the SUMOylation on K193 is enhanced by the S199D phosphomimic mutant. Using an ING1b protein mutated at the major SUMOylation site (ING...

    Ameloblastoma is the most frequently encountered odontogenic tumor, characterized by a locally invasive behavior, frequent recurrences, and, although rare, metastatic capacity. Loss or inactivation of tumor suppressor genes (TSGs) allows cells to acquire neoplastic growth. The ING family proteins are tumor suppressors that physically and functionally interact with p53 to perform important roles in apoptosis, DNA repair, cell cycle regulation, and senescence. TP53 genetic alterations were reported to infrequently occur in ameloblastoma. Considering that other TSGs related to TP53 could be altered in this tumor, we focused our study on the ING family genes. We analyzed the loss of heterozygosity (LOH) status of the ING family (ING1-ING5) chromosomal loci in a group of ameloblastomas by microsatellite analysis, and correlated the ING LOH status with clinicopathological characteristics. By using specific microsatellite markers, high frequency of LOH was found at the loci of each ING gene family member (33.3-72.2%). A significant relationship was shown between LOH of D2S 140 (ING5 locus) and solid tumor type (p = 0.02). LOH of ING3MS (ING3 locus) was also high in solid type tumors, showing a near significant association. In addition, a notable tendency toward higher LOH for half of the markers was observed in recurrent cases. LOH of ING family genes appears as a common genetic alteration in solid ameloblastoma. The current study provides interesting novel information regarding the potential prognostic significance of the allelic loss of the ING gene family loci in ameloblastoma tumorigenesis.

  20. Modulators of inhibitor of growth (ING) family expression in development and disease.

    2009-05-01

    The inhibitor of growth (ING) gene family proteins regulate many critical cellular processes such as cell proliferation and growth, apoptosis, DNA repair, senescence, angiogenesis, and drug resistance. Their transcripts and proteins are differentially expressed in health and disease and there is evidence for developmental regulation. The vast majority of studies have characterized ING levels in the context of cancer. However, relatively little attention has been paid to the expression of ING family members in other contexts. This review summarizes the findings from human and animal model systems that provide insight into the factors influencing the expression of these important proteins. We examine the influence of cell cycle and aging as well as genotoxic stress on ING expression levels and evaluate several emerging areas of inquiry demonstrating that ING gene activity may be modulated by factors such as the p53 tumor suppressor, DNA methylation, and ING proteins themselves with external factors such as hormones, reactive oxygen species, TGFbeta signalling, and other proteins of pathological significance also influencing ING levels. We then briefly discuss the influence of post-translational modification and changes in subcellular localization as it pertains to modulation of ING expression. Understanding how ING expression is modulated represents a vital aspect of effective drug targeting strategies.

    The INhibitor of Growth (ING) family of type II tumor suppressors (ING1-ING5) is involved in many cellular processes such as cell aging, apoptosis, DNA repair and tumorigenesis. To expand our understanding of the proteins with which the ING proteins interact, we designed a method that did not depend upon large-scale proteomics-based methods, since they may fail to highlight transient or relatively weak interactions. Here we test a cross-species (yeast, fly, and human) bioinformatics-based approach to identify potential human ING-interacting proteins with higher probability and accuracy than approaches based on screens in a single species. We confirm the validity of this screen and show that ING1 interacts specifically with three of the three proteins tested; p38MAPK, MEKK4 and RAD50. These novel ING-interacting proteins further link ING proteins to cell stress and DNA damage signaling, providing previously unknown upstream links to DNA damage response pathways in which ING1 participates. The bioinformatics approach we describe can be used to create an interaction prediction list for any human proteins with yeast homolog(s). None of the validated interactions were predicted by the conventional protein-protein interaction tools we tested. Validation of our approach by traditional laboratory techniques shows that we can extract value from the voluminous weak interaction data already elucidated in yeast and fly databases. We therefore propose that the weak (low signal to noise ratio) data from large-scale interaction datasets are currently underutilized.

In Lithuanian it became stressed as a result of Saussure-Fortunatov’s law, i.e. in the period when syllable intonations were distinguished in both stressed and unstressed syllables, whereas the stress of OPr. -īng- might be posterior to a possible neutralisation of syllable intonations in unstressed syllables. Alternatively, at least some of the attested OPr. examples with -īng- can be interpreted as contracted from forms with -īwing-, cf. wertīngs : wertīwings.

    Reflective thinking is an important component in the world of education, especially in professional education of teachers. In learning mathematics, reflective thinking is one way to solve mathematical problem because it can improve student's curiosity when student faces a mathematical problem. Reflective thinking is also a future competence that should be taught to students to face the challenges and to respond of demands of the 21st century. There are many factors which give impact toward the student's reflective thinking when student solves mathematical problem. One of them is cognitive style. For this reason, reflective thinking and cognitive style are important things in solving contextual mathematical problem. This research paper describes aspect of reflective thinking in solving contextual mathematical problem involved solution by using some mathematical concept, namely linear program, algebra arithmetic operation, and linear equations of two variables. The participant, in this research paper, is a male-prospective teacher who has Field Dependent. The purpose of this paper is to describe aspect of prospective teachers' reflective thinking in solving contextual mathematical problem. This research paper is a descriptive by using qualitative approach. To analyze the data, the researchers focus in four main categories which describe prospective teacher's activities using reflective thinking, namely; (a) formulation and synthesis of experience, (b) orderliness of experience, (c) evaluating the experience and (d) testing the selected solution based on the experience.

    This study sought to verify if a history of maltreatment may predict the psychosocial profile of children who participated in an intervention program aiming at reducing sexual behavior problems. Data were collected at both the beginning and the end of the intervention program using a clinical protocol and standardized tests selected on the basis of the intervention targets. In general, the results indicate that children who had experienced maltreatment display a psychosocial profile that is similar to that of children who had not experienced maltreatment. However, children who had experienced psychological abuse or neglect may display greater externalized or sexualized behaviors, whereas children who have a parent who had been a victim of sexual abuse may display fewer sexualized behaviors.

    The Inhibitor of Growth (ING) gene family is an emerging putative type II tumor suppressor gene (TSG). Proteins of INGs (ING1-5), critical modulator of the histone code via PHD fingers, are able to suppress cell growth and proliferation, induce apoptosis, and modulate cell cycle progression. ING proteins are involved in transcriptional regulation of genes, such as the p53-inducible gene p21. ING proteins also serve as shuttling proteins between nucleus and cytoplasm, and dysregulation of this nucleocytoplasmic traffic has been shown in some cancer cells. In cancer cells, ING mRNA levels are often lost or suppressed but the genes are rarely mutated. Recently the potential roles of ING proteins as prognostic biomarkers, detection of aggressive behavior of the tumor as well as prediction of chemo-radiotherapy response have also emerged. In this review, we summarize the up-to-date knowledge on functions of the ING proteins, the protein status in human tumors and discuss as a potential target in the molecular diagnostics and therapy of cancer.

  7. Regulation of p53 by ING family members in suppression of tumor initiation and progression.

    2012-06-01

    The INhibitor of Growth (ING) family is an evolutionarily conserved set of proteins, implicated in suppression of initiation and progression of cancers in various tissues. They promote cell cycle arrest, cellular senescence and apoptosis, participate in stress responses, regulate DNA replication and DNA damage responses, and inhibit cancer cell migration, invasion, and angiogenesis of the tumors. At the molecular level, ING proteins are believed to participate in chromatin remodeling and transcriptional regulation of their target genes. However, the best known function of ING proteins is their cooperation with p53 tumor suppressor protein in tumor suppression. All major isoforms of ING family members can promote the transactivition of p53 and the majority of them are shown to directly interact with p53. In addition, ING proteins are thought to interact with and modulate the function of auxiliary members of p53 pathway, such as MDM2, ARF , p300, and p21, indicating their widespread involvement in the regulation and function of this prominent tumor suppressor pathway. It seems that p53 pathway is the main mechanism by which ING proteins exert their functions. Nevertheless, regulation of other pathways which are not relevant to p53, yet important for tumorigenesis such as TGF-β and NF-κB, by ING proteins is also observed. This review summarizes the current understanding of the mutual interactions and cooperation between different members of ING family with p53 pathway and implications of this cooperation in the suppression of cancer initiation and progression.

    The ING4 tumor suppressor plays a significant role in various cancer-related cellular processes. AUF1 affects the stability and/or translation of multiple mRNAs via binding to an AU-rich element in the 3'-untranslated regions. In this study, we identify AUF1 as a novel and direct binding partner of ING4. mRNP immunoprecipitation assays indicated that ING4, AUF1 and MYC mRNA present in the same mRNP complex. ING4 suppressed MYC protein expression without altering MYC mRNA levels, and abolished the cell proliferation induced by AUF1 in K562 cells. These results suggest that ING4 may regulate MYC translation by its association with AUF1. Copyright © 2013 Federation of European Biochemical Societies. Published by Elsevier B.V.

    The aim of the study was to assess patients' socio-demographic factors with their removable prosthesis in general, as well as to assess their problems with the functional limitation, physical pain, psychological discomfort, physical disability, social disability, and handicap investigate impaired oral health-related quality of life (OHRQoL) in patient treated with removable dentures before treatment and at 1 and 12 months after treatment. The first part of the questionnaire was comprised of 20 questions. It was designed in four different sections as: (i) general socio-demographic factors, (ii) general health, (iii) experience and use of dental and denture care, and (iv) anamnestic sign and symptoms of temporomandibular disorders (TMD). A statistical analysis system (SAS) was used for data management and analysis. Patient-reported problems were studied using the item list contained in the Turkish version of the oral health impact profile (OHIP) in a convenience sample of 136 prosthodontic patients before (m(0)), 1 month after (m(1)), and 12 months (m(2)) after treatment were then examined by using two-way ANOVA with repeated measurement. Differences in OHRQoL were present when item-specific prevalence was stratified by time of total scores; gender, residential area, working status, self-reported general health, smoking status, denture type, importance of the convenient dental care, trauma story, self-reported TMD/pain, and self-reported TMD/difficulty opening mouth wide. At baseline, the most prevalent frequently reported problems "difficulties chewing" (49.3%), "digestion worse" (40.4%), "take longer to complete a meal" (36%), "food catching" (30.9%), and "dentures not fitting" (29.4%), and m(2) the most prevalent frequently reported problems were "avoid going out" (25%), "difficulties chewing" (17.6), "sore jaw" (15.5%), and "take longer to complete a meal" (14%). The study confirmed that denture status is by far the strongest predictor of impaired OHRQoL compared

    Full Text Available One-dimensional steady-state heat transfer in fins of different profiles is studied. The problem considered satisfies the Dirichlet boundary conditions at one end and the Neumann boundary conditions at the other. The thermal conductivity and heat coefficients are assumed to be temperature dependent, which makes the resulting differential equation highly nonlinear. Classical Lie point symmetry methods are employed, and some reductions are performed. Some invariant solutions are constructed. The effects of thermogeometric fin parameter, the exponent on temperature, and the fin efficiency are studied.

    2008-01-01

    Full Text Available Abstract Background The Perceived Impact of Problem Profile (PIPP was developed to provide a tool for measuring the impact of a health condition from the individual's perspective, using the ICF model as a framework. One of the aims of the ICF is to enable the comparison of data across countries, however, relatively little is known about the subjective experience of disability in middle and low-income countries. The aim of this study was to assess the validity of the Perceived Impact of Problem Profile (PIPP for use among adults with a disability in Thailand using Rasch analysis. Methods A total of 210 adults with mobility impairment from the urban, rural and remote areas of northeast Thailand completed the PIPP, which contains 23 items assessing both impact and distress across five key domains (Self-care, Mobility, Participation, Relationships, and Psychological Well-being. Rasch analysis, using RUMM2020, was conducted to assess the internal validity and psychometric properties of the PIPP Impact subscales. Validation of the PIPP Impact scales was conducted by comparing scores across the different response levels of the EQ5D items. Results Rasch analysis indicated that participants did not clearly differentiate between 'impact' and 'distress,' the two aspects assessed by the PIPP. Further analyses were therefore limited to the PIPP Impact subscales. These showed adequate psychometric properties, demonstrating fit to the Rasch model and good person separation reliability. Preliminary validity testing using the EQ5D items provided support for the PIPP Impact subscales. Conclusion The results provide further support for the psychometric properties of the PIPP Impact scales and indicate that it is a suitable tool for use among adults with a locomotor disability in Thailand. Further research is needed to validate the PIPP across different cultural contexts and health conditions and to assess the usefulness of separate Impact and Distress subscales.

  15. Correlation of colluvial deposits with the modern land surface and the problem of slope profile description

    Mitusov, A. V.; Mitusova, O. E.; Wendt, J.; Dreibrodt, S.; Bork, H.-R.

    2014-09-01

    This article focuses on features of spatial distribution of colluvial (slope) deposits on a micro scale. These features were detected by the non-parametric rank correlation of Spearman (rS) between thickness of colluvial layers and morphometric variables (MVs) of the modern land surface. The strongest correlation was found between total thickness of colluvial layers and maximal catchment area (rS = 0.85). A negative correlation was observed between thicknesses of younger and older colluvial layers. Additionally, if young colluvial layers have a negative correlation with slope steepness (GA), relatively old buried colluvial layers have a positive correlation with GA. These facts indicate an inversion of the zones of actual matter accumulation due to transformation of the land surface in profile during long-term sedimentation. Vertical curvature (kv) characterises acceleration and deceleration of surface flow caused by the shape of the slope profile along flow lines. Based on this, it was expected that kv would have a direct impact on the accumulation of colluvium. However, in this study, the correlations between the thickness of colluvial deposits and kv were low. Functional relationships between colluvial accumulation and the shape of profiles along flow lines were reflected by correlations with GA. Based on these observations, it is assumed that the regional nature of surface flow velocity affects the shift between existing accumulation zones reflected by colluvial deposits and potential accumulation zones reflected by MVs. Signs of correlation coefficients between the thickness of colluvial deposits and curvatures reflect the tendency of increased colluvial depositions at three out of 12 local landforms of Shary's classification. These landforms are located in the valley bottom. The mean thickness of colluvial deposits at these three landforms was 167 ± 18.7 cm (error range = standard deviation); the other nine landforms show a mean thickness of 130.1 ± 34.1 cm.

  16. The ING gene family in the regulation of cell growth and tumorigenesis.

    2009-01-01

    The five members of the inhibitor of growth (ING) gene family have garnered significant interest due to their putative roles as tumor suppressors. However, the precise role(s) of these ING proteins in regulating cell growth and tumorigenesis remains uncertain. Biochemical and molecular biological analysis has revealed that all ING members encode a PHD finger motif proposed to bind methylated histones and phosphoinosital, and all ING proteins have been found as components of large chromatin remodeling complexes that also include histone acetyl transferase (HAT) and histone deacetylase (HDAC) enzymes, suggesting a role for ING proteins in regulating gene transcription. Additionally, the results of forced overexpression studies performed in tissue culture have indicated that several of the ING proteins can interact with the p53 tumor suppressor protein and/or the nuclear factor-kappa B (NF-kappaB) protein complex. As these ING-associated proteins play well-established roles in numerous cell processes, including DNA repair, cell growth and survival, inflammation, and tumor suppression, several models have been proposed that ING proteins act as key regulators of cell growth not only through their ability to modify gene transcription but also through their ability to alter p53 and NF-kappaB activity. However, these models have yet to be substantiated by in vivo experimentation. This review summarizes what is currently known about the biological functions of the five ING genes based upon in vitro experiments and recent mouse modeling efforts, and will highlight the potential impact of INGs on the development of cancer.

    This study identified clinical profiles of referred children based on the severity of callous-unemotional (CU) traits, emotional difficulties, and conduct problems. Parents of 166 children (132 males) aged 6-12 years referred to a hospital clinic because of disruptive behavior completed measures to assess these key indicators, and person-centered analysis was used to identify profiles. Four distinct profiles were identified that include: (1) Children low in severity on the three domains, (2) Children high in severity on the three domains, (3) Children high in severity in conduct problems and CU traits with minimal emotional difficulties, and (4) Children high in severity in conduct problems and emotional difficulties with minimal CU traits. Profiles differed in degree of aggression and behavioral impairment. Findings show that clinic-referred children with disruptive behaviors can be grouped based on these important indicators into profiles that have important implications for assessment and treatment selection.

    Full Text Available Abstract : This article describes two classroom activities, "Profiling" and "Pause Analysis", that can be successfully used in ESL writing classes. "Profiling" addresses such problems as poor development of ideas, simplistic ideas, and lack of coherence in written texts. "Pause Analysis" focusses on the thinking processes that students engage in while drafting text, processes such as searching for ideas, evaluat­ing ideas, and postponing ideas. Both activities enable the instructor to assume the role of intervener in the students' writing processes, rather than evaluator of the text produced. In drawing The attention of the student write to both product and process, "Profiling" and "Pause Analysis" help them develop an awareness of the relation-ship between ideas in English expository text and the thinking pro­cesses that writers engage in while drafting such text.

    2011-01-01

    Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer in the world. The evolution and progression of HNSCC are considered to result from multiple stepwise alterations of cellular and molecular pathways in squamous epithelium. Recently, inhibitor of growth gene (ING) family consisting of five genes, ING1 to ING5, was identified as a new tumor suppressor gene family that was implicated in the downregulation of cell cycle and chromatin remodeling. In contrast, it has been shown that ING1 and ING2 play an oncogenic role in some cancers, this situation being similar to TGF-β. In HNSCC, the ING family has been reported to be downregulated, and ING translocation from the nucleus to the cytoplasm may be a critical event for carcinogenesis. In this paper, we describe our recent results and briefly summarize current knowledge regarding the biologic functions of ING in HNSCC.

    Full Text Available Gambling has seen a significant increase in Italy in the last 10 years and has rapidly become a public health issue, and for these reasons the first National Helpline for Problem Gambling (GR-Helpline has been established. The aims of this study are to describe the GR-Helpline users’ characteristics and to compare the prevalence rates of the users with those of moderate-risk/problematic gamblers obtained from the national survey (IPSAD 2010-2011. Statistical analysis was performed on data obtained from the counselling sessions (phone/e-mail/chat carried out on 5,805 users (57.5% gamblers; 42.5% families/friends. This confirms that the problems related to gambling concern not only the gamblers but also their families and friends. Significant differences were found between gamblers and families/friends involving gender (74% of gamblers were male; 76.9% of families/friends were female, as well as age-classes and geographical area. Female gamblers had a higher mean age (47.3 versus 40.2 years and preferred nonstrategy-based games. Prevalence rates of GR-Helpline users and of moderate risk/problematic gamblers were correlated (Rho = 0.58; p=0.0113. The results highlight the fact that remote access to counselling can be an effective means of promoting treatment for problem gamblers who do not otherwise appeal directly for services.

    We assessed severely and persistently depressed patients' interpersonal self-efficacy, problems, and goals, plus changes in interpersonal functioning and depression during 20 weeks of group therapy. Outpatients (32 female, 26 male, mean age = 45 years) completed interpersonal circumplex measures of goals, efficacy, and problems before completing 20 weeks of manualized group therapy, during which we regularly assessed depression and interpersonal style. Compared to normative samples, patients lacked interpersonal agency, including less self-efficacy for expressive/assertive actions; stronger motives to avoid conflict, scorn, and humiliation; and more problems with being too submissive, inhibited, and accommodating. Behavioral Activation and especially Cognitive Behavioral Analysis System of Psychotherapy interventions produced improvements in depression and interpersonal agency, with increases in "agentic and communal" efficacy predicting subsequent decreases in depression. While severely and persistently depressed patients were prone to express maladaptive interpersonal dispositions, over the course of group therapy, they showed increasingly agentic and beneficial patterns of cognitions, motives, and behaviors. © 2016 Wiley Periodicals, Inc.

    The objectives of this study were, first, to explore the prevalence of aggressors with lifetime intimate partner violence (IPV) among patients in the Proyecto Hombre of Navarra (Spain) addiction treatment programme; and second, to know the specific and differential characteristics of patients presenting IPV as aggressors. A sample of 162 patients (119 men and 43 women) was assessed. Data on socio-demographic and substance consumption characteristics, IPV variables, psychopathological symptoms, and personality variables were obtained. The profiles of patients in addiction treatment with and without a history of violence towards their partners were compared. The results showed that 33.6% of people in treatment for addiction had committed violence against their partners. This prevalence was significantly higher (χ(2)  = 15.6, p woman was one of the main predictors of committing IPV. © American Academy of Addiction Psychiatry.

    Recently, the role of food and nutrition in preventing or delaying chronic disability in the elderly population has received great attention. Thanks to their ability to influence biochemical and biological processes, bioactive nutrients are considered modifiable factors capable of preserving a healthy brain status. A diet rich in vitamins and polyphenols and poor in saturated fatty acids has been recommended. In the prospective of a healthy diet, cooking methods should be also considered. In fact, cooking procedures can modify the original dietary content, contributing not only to the loss of healthy nutrients, but also to the formation of toxins, including advanced glycation end products (AGEs). These harmful compounds are adsorbed at intestinal levels and can contribute to the ageing process. The accumulation of AGEs in ageing ("AGE-ing") is further involved in the exacerbation of neurodegenerative and many other chronic diseases. In this review, we discuss food's dual role as both source of bioactive nutrients and reservoir for potential toxic compounds-paying particular attention to the importance of proper nutrition in preventing/delaying Alzheimer's disease. In addition, we focus on the importance of a good education in processing food in order to benefit from the nutritional properties of an optimal diet.

    Abstract Repetitive mild traumatic brain injury (mTBI), such as that experienced by contact-sport athletes, has been associated with the development of chronic traumatic encephalopathy (CTE). Executive dysfunction is believed to be among the earliest symptoms of CTE, with these symptoms presenting in the fourth or fifth decade of life. The present study used a well-validated self-report measure to study executive functioning in football players, compared to healthy adults. Sixty-four college and professional football players were administered the Behavior Rating Inventory of Executive Function, adult version (BRIEF-A) to evaluate nine areas of executive functioning. Scores on the BRIEF-A were compared to published age-corrected normative scores for healthy adults Relative to healthy adults, the football players indicated significantly more problems overall and on seven of the nine clinical scales, including Inhibit, Shift, Emotional Control, Initiate, Working Memory, Plan/Organize, and Task Monitor. These symptoms were greater in athletes 40 and older, relative to younger players. In sum, football players reported more-frequent problems with executive functioning and these symptoms may develop or worsen in the fifth decade of life. The findings are in accord with a growing body of evidence that participation in football is associated with the development of cognitive changes and dementia as observed in CTE. PMID:23421745

    Santander-García, M.; Rodríguez-Gil, P.; Tulloch, S.; Rutten, R. G. M.

    Present and future key instruments at the Isaac Newton Group of Telescopes (ING) are introduced, and their corresponding latest scientific highlights are presented. GLAS (Ground-layer Laser Adaptive optics System): The recently installed 515 nm laser, mounted on the WHT (William Herschel Telescope), produces a bright artificial star at a height of 15 km. This enables almost full-sky access to Adaptive Optics observations. Recent commissioning observations with the NAOMI+GLAS system showed that very significant improvement in image quality can be obtained, e.g. down to 0.16 arcsec in the H band. QUCAM2 and QUCAM3: Two Low Light Level (L3) CCD cameras for fast or faint-object spectroscopy with the twin-armed ISIS spectrograph at the WHT. Their use opens a new window of high time-frequency observations, as well as access to fainter objects. They are powerful instruments for research on compact objects such as white dwarfs, neutron stars or black holes, stellar pulsations, and compact binaries.HARPS-NEF (High-Accuracy Radial-velocity Planet Searcher of the New Earths Facility): An extremely stable, high-resolution (R ˜ 120, 000) spectrograph for the WHT which is being constructed for commissioning in 2009-2010. Its radial velocity stability of < 1 m s- 1 may in the future be even further improved by using a Fabry-Perot laser-comb, a wavelength calibration unit capable of achieving an accuracy of 1 cm s- 1. This instrument will effectively allow to search for earth-like exoplanets.

    The Isaac Newton Group, after nearly 30 years of productive operation of the William Herschel, Isaac Newton and Jacobus Kapteyn telescopes, is reviewing its science focus. The central goal is to respond to the changes in the astronomical landscapes in UK, the Netherlands, and especially in Spain, now a mature world-player community with access to 10-m class telescopes on La Palma and Paranal. The current model, which exploits scientific and instrumentation diversity, will continue to be offered until 2017. In the meantime, an ING-led consortium is building WEAVE, a next-generation spectroscopic facility for the WHT. WEAVE is a multi-fibre system capable of deploying either 1000 single-fibre probes, 25 mini-IFUs or a single large IFU, to feed a two-arm bench spectrograph which delivers resolving powers of either 5000 or 20,000. WEAVE will exploit a new field corrector at the WHT that enlarges the prime-focus FOV diameter from the current 40 arcmin to 2 degrees. WEAVE will be used to carry out massive surveys that exploit Gaia data in topics of Milky Way astronomy and stellar evolution; surveys that carry out galaxy evolution studies linked to various multi-wavelength surveys, including the LOFAR radio telescope; and redshift surveys of distant galaxies for cosmology. Community fibres will be available. The expectation is that these surveys will use 70% of the WHT time until at least 2022. The rest of the time will be available via normal TAC allocations, for use of facility instrumentation. Plans for the INT include involving external institutions in the provision of new instrumentation and/or telescope upgrades in exchange for significant fractions of telescope time.

    2012-12-01

    Employing a developmental and ecological model, the study identified initial levels and rates of change in academic skills for subgroups of preschool children exhibiting problem behavior within routine classroom situations. Six distinct latent profile types of emotional and behavioral adjustment were identified for a cohort of low-income children early in the preschool year (N=4417). Profile types provided a descriptive picture of patterns of classroom externalizing, internalizing, and situational adjustment problems common to subgroups of children early in the preschool year. The largest profile type included children who exhibited low problem behavior and were characterized as well-adjusted to the preschool classroom early in the year. The other profile types were characterized by distinct combinations of elevated internalizing, externalizing, and situational problem behavior. Multinomial logistic regression identified younger children and boys at increased risk for classification in problem types, relative to the well-adjusted type. Latent growth models indicated that children classified within the extremely socially and academically disengaged profile type, started and ended the year with the lowest academic skills, relative to all other types. Implications for future research, policy, and practice are discussed. Copyright © 2012 Society for the Study of School Psychology. Published by Elsevier Ltd. All rights reserved.

    2006-06-01

    Full Text Available Abstract Background The aim of this study was to develop and conduct preliminary validation of the Perceived Impact of Problem Profile (PIPP. Based on the biopsychosocial model of health and functioning, the PIPP was intended as a generic research and clinical measurement tool to assess the impact and distress of health conditions from the individuals' perspective. The ICF classification system was used to guide the structure of the PIPP with subscales included to assess impact on self-care, mobility, participation, relationships and psychological well-being. While the ICF focuses on the classification of objective health and health related status, the PIPP broadens this focus to address the individuals' subjective experience of their health condition. Methods An item pool of 23 items assessing both impact and distress on five key domains was generated. These were administered to 169 adults with mobility impairment. Rasch analysis using RUMM2020 was conducted to assess the psychometric properties of each set of items. Preliminary construct validation of the PIPP was performed using the EQ5D. Results For both the Impact and Distress scales of the PIPP, the five subscales (Self-care, Mobility, Participation, Relationships, and Psychological Well-being showed adequate psychometric properties, demonstrating fit to the Rasch model. All subscales showed adequate person separation reliability and no evidence of differential item functioning for sex, age, educational level or rural vs urban residence. Preliminary validity testing using the EQ5D items provided support for the subscales. Conclusion This preliminary study, using a sample of adults with mobility impairment, provides support for the psychometric properties of the PIPP as a potential clinical and research measurement tool. The PIPP provides a brief, but comprehensive means to assess the key ICF components, focusing on the individuals' perspective of the impact and distress caused by their

  16. ING1 and 5-azacytidine act synergistically to block breast cancer cell growth.

    Directory of Open Access Journals (Sweden)

    Satbir Thakur

    Full Text Available Inhibitor of Growth (ING proteins are epigenetic "readers" that recognize trimethylated lysine 4 of histone H3 (H3K4Me3 and target histone acetyl transferase (HAT and histone deacetylase (HDAC complexes to chromatin.Here we asked whether dysregulating two epigenetic pathways with chemical inhibitors showed synergistic effects on breast cancer cell line killing. We also tested whether ING1 could synergize better with chemotherapeutics that target the same epigenetic mechanism such as the HDAC inhibitor LBH589 (Panobinostat or a different epigenetic mechanism such as 5-azacytidine (5azaC, which inhibits DNA methyl transferases. Simultaneous treatment of breast cancer cell lines with LBH589 and 5azaC did not show significant synergy in killing cells. However, combination treatment of ING1 with either LBH589 or 5azaC did show synergy. The combination of ING1b with 5azaC, which targets two distinct epigenetic mechanisms, was more effective at lower doses and enhanced apoptosis as determined by Annexin V staining and cleavage of caspase 3 and poly-ADP-ribose polymerase (PARP. ING1b plus 5azaC also acted synergistically to increase γH2AX staining indicating significant levels of DNA damage were induced. Adenoviral delivery of ING1b with 5azaC also inhibited cancer cell growth in a murine xenograft model and led to tumor regression when viral concentration was optimized in vivo.These data show that targeting distinct epigenetic pathways can be more effective in blocking cancer cell line growth than targeting the same pathway with multiple agents, and that using viral delivery of epigenetic regulators can be more effective in synergizing with a chemical agent than using two chemotherapeutic agents. This study also indicates that the ING1 epigenetic regulator may have additional activities in the cell when expressed at high levels.

  1. Modulation of thyroid hormone-dependent gene expression in Xenopus laevis by INhibitor of Growth (ING) proteins.

    INhibitor of Growth (ING) proteins belong to a large family of plant homeodomain finger-containing proteins important in epigenetic regulation and carcinogenesis. We have previously shown that ING1 and ING2 expression is regulated by thyroid hormone (TH) during metamorphosis of the Xenopus laevis tadpole. The present study investigates the possibility that ING proteins modulate TH action. Tadpoles expressing a Xenopus ING2 transgene (Trans(ING2)) were significantly smaller than tadpoles not expressing the transgene (Trans(GFP)). When exposed to 10 nM 3,5,3'-triiodothyronine (T(3)), premetamorphic Trans(ING2) tadpoles exhibited a greater reduction in tail, head, and brain areas, and a protrusion of the lower jaw than T(3)-treated Trans(GFP) tadpoles. Quantitative real time polymerase chain reaction (QPCR) demonstrated elevated TH receptor β (TRβ) and TH/bZIP transcript levels in Trans(ING2) tadpole tails compared to Trans(GFP) tadpoles while TRα mRNAs were unaffected. In contrast, no difference in TRα, TRβ or insulin-like growth factor (IGF2) mRNA abundance was observed in the brain between Trans(ING2) and Trans(GFP) tadpoles. All of these transcripts, except for TRα mRNA in the brain, were inducible by the hormone in both tissues. Oocyte transcription assays indicated that ING proteins enhanced TR-dependent, T(3)-induced TRβ gene promoter activity. Examination of endogenous T(3)-responsive promoters (TRβ and TH/bZIP) in the tail by chromatin immunoprecipitation assays showed that ING proteins were recruited to TRE-containing regions in T(3)-dependent and independent ways, respectively. Moreover, ING and TR proteins coimmunoprecipitated from tail protein homogenates derived from metamorphic climax animals. We show for the first time that ING proteins modulate TH-dependent responses, thus revealing a novel role for ING proteins in hormone signaling. This has important implications for understanding hormone influenced disease states and suggests that the

    Angiogenesis/angiostasis regulated by hypoxia inducible factor-1A (HIF-1A)/vascular endothelial growth factor (VEGF)/inhibitor of growth protein 4 (ING-4) axis may be crucial for the course and outcome of sarcoidosis. Overexpression of angiogenic factors (activation of VEGF through HIF-1A) may predispose to chronic course and lung fibrosis, whereas immunoangiostasis (related to an overexpression of inhibitory ING-4) may be involved in granuloma formation in early sarcoid inflammation, or sustained or recurrent formation of granulomas. In this work we investigated gene expression of HIF-1A, VEGF and ING-4 in bronchoalveolar fluid (BALF) cells and in peripheral blood (PB) lymphocytes of sarcoidosis patients (n=94), to better understand mechanisms of the disease and to search for its biomarkers. The relative gene expression level (RQ value) was analyzed by qPCR. The results were evaluated according to the presence of lung parenchymal involvement (radiological stage I vs. II-IV), acute vs. insidious onset, lung function tests, calcium metabolism parameters, percentage of lymphocytes (BALL%) and BAL CD4+/CD8+ in BALF, age, and gender. In BALF cells, the ING-4 and VEGF RQ values were increased, while HIF-1A expression was decreased. In PB lymphocytes all studied genes were overexpressed. Higher expression of HIF-1A in PB lymphocytes of patients with abnormal spirometry, and in BALF cells of patients with lung volume restriction was found. VEGF gene expression in BALF cells was also higher in patients with abnormal spirometry. These findings were in line with previous data on the role of HIF-1A/VEGF/ING-4 axis in the pathogenesis of sarcoidosis. Up-regulated HIF-1A and VEGF genes are linked to acknowledged negative prognostics.

Such profiles have a small thickness and complex cross-sectional shape. Bending deformation develops in the cross-sectional plane under the influence of loads in beam. In addition, deformation of constrained torsion and warping arise. These deformations influence the stress distribution at the points of the cross-section of the beam and thereby determine its load-bearing capacity.

    1997-04-01

    Gender differences were analyzed in a sample of 233 (83 women, 150 men) problem drinkers treated at the same clinic. Demographic and family history measures showed few gender differences. Men reported more alcohol consumption than did women, but patterns of drinking and intoxication levels were similar. Males reported drinking and intoxication at an earlier age, more beer and less wine drinking and more drinking away from home and driving after drinking. Women reported more negative emotional effects of drinking and more spouses with alcohol problems. Despite similar problem duration, men showed more lifetime alcohol problems but not dependence signs. Men were more likely to accept a disease concept of alcoholism. Rates of smoking, other drug use, and other life problems were similar.

  15. Loss of inhibitor of growth (ING-4) is implicated in the pathogenesis and progression of human astrocytomas.

    Inhibitor of growth 4 (ING-4) is a tumor suppressor gene that interacts with nuclear factor-kappaB (NF-kappaB) and represses its transcriptional activity. Several lines of evidence suggest that the tumor suppressor gene ING-4, the transcription factor NF-kappaB and its target genes matrix metalloproteases MMP-2, MMP-9 and urokinase plasminogen activator (u-PA) are critically involved in tumor invasion. The aim of the present study was to investigate immunohistochemically the expression pattern of ING-4, NF-kappaB and the NF-kappaB downstream targets MMP-2, MMP-9 and u-PA in human astrocytomas from 101 patients. We found that ING-4 expression was significantly decreased in astrocytomas, and ING-4 loss was associated with tumor grade progression. Expression of p65, a NF-kappaB subunit, was significantly higher in grade IV than in grade III and grade I/II tumors, and a statistical significant negative correlation between expression of ING-4 and expression of nuclear p65 was noticed. MMP-9, MMP-2 and u-PA were overexpressed in human astrocytomas. Of note, astrocytomas of advanced histologic grades (grade III, IV) displayed significantly higher expression levels of these proteins compared to tumors of lower grades (grade I, II). Collectively, our data suggest an essential role for ING-4 in human astrocytoma development and progression possibly through regulation of the NF-kappaB-dependent expression of genes involved in tumor invasion.

  20. The Caenorhabditis elegans ing-3 gene regulates ionizing radiation-induced germ-cell apoptosis in a p53-associated pathway.

    Science.gov (United States)

    Luo, Jingjing; Shah, Sitar; Riabowol, Karl; Mains, Paul E

    2009-02-01

    The inhibitor of growth (ING) family of type II tumor suppressors are encoded by five genes in mammals and by three genes in Caenorhabditis elegans. All ING proteins contain a highly conserved plant homeodomain (PHD) zinc finger. ING proteins are activated by stresses, including ionizing radiation, leading to the activation of p53. ING proteins in mammals and yeast have recently been shown to read the histone code in a methylation-sensitive manner to regulate gene expression. Here we identify and characterize ing-3, the C. elegans gene with the highest sequence identity to the human ING3 gene. ING-3 colocalizes with chromatin in embryos, the germline, and somatic cells. The ing-3 gene is part of an operon but is also transcribed from its own promoter. Both ing-3(RNAi) and ing-3 mutant strains demonstrate that the gene likely functions in concert with the C. elegans p53 homolog, cep-1, to induce germ-cell apoptosis in response to ionizing radiation. Somatically, the ing-3 mutant has a weak kinker uncoordinated (kinker Unc) phenotype, indicating a possible neuronal function.

  1. The inhibitor of growth protein 5 (ING5 depends on INCA1 as a co-factor for its antiproliferative effects.

    Directory of Open Access Journals (Sweden)

    Feng Zhang

    Full Text Available The proteins of the Inhibitor of Growth (ING family are involved in multiple cellular functions such as cell cycle regulation, apoptosis, and chromatin remodeling. For ING5, its actual role in growth suppression and the necessary partners are not known. In a yeast-two-hybrid approach with human bone marrow derived cDNA, we identified ING5 as well as several other proteins as interaction partners of Inhibitor of cyclin A1 (INCA1 that we previously characterized as a novel interaction partner of cyclin A1/CDK2. ING5 expression in leukemic AML blasts was severely reduced compared to normal bone marrow. In line, ING5 inhibited bone marrow colony formation upon retroviral transduction. However, Inca1(-/- bone marrow colony formation was not suppressed by ING5. In murine embryonic fibroblast (MEF cells from Inca1(+/+ and Inca1(-/- mice, overexpression of ING5 suppressed cell proliferation only in the presence of INCA1, while ING5 had no effect in Inca1(-/- MEFs. ING5 overexpression induced a delay in S-phase progression, which required INCA1. Finally, ING5 overexpression enhanced Fas-induced apoptosis in Inca1(+/+ MEFs, while Inca1(-/- MEFs were protected from Fas antibody-induced apoptosis. Taken together, these results indicate that ING5 is a growth suppressor with suppressed expression in AML whose functions depend on its interaction with INCA1.

    2000-04-01

    The restrictions of the magnetic diagnostics are discussed. Being related to the integral nature of the measurable quantities, they follow from the fundamental laws of electromagnetism. A series of particular examples demonstrating the strength of these restrictions is given and analyzed. A general rule is emphasized that the information obtained from external magnetic measurements is obviously insufficient for the reliable evaluation of plasma current and pressure profiles in tokamaks or in stellarators. The underlying reason is that outside the plasma the own field of the equilibrium plasma currents is determined by the boundary conditions on the plasma surface only. (author)

    This paper contains two parts revolving around Monte Carlo transport simulation on Intel Many Integrated Core coprocessors (MIC, also known as Xeon Phi). (1) MCNP 6.1 was recompiled into multithreading (OpenMP) and multiprocessing (MPI) forms respectively without modification to the source code. The new codes were tested on a 60-core 5110P MIC. The test case was FS7ONNi, a radiation shielding problem used in MCNP's verification and validation suite. It was observed that both codes became slower on the MIC than on a 6-core X5650 CPU, by a factor of 4 for the MPI code and, abnormally, 20 for the OpenMP code, and both exhibited limited capability of strong scaling. (2) We have recently added a Constructive Solid Geometry (CSG) module to our ARCHER code to provide better support for geometry modelling in radiation shielding simulation. The functions of this module are frequently called in the particle random walk process. To identify the performance bottleneck we developed a CSG proxy application and profiled the code using the geometry data from FS7ONNi. The profiling data showed that the code was primarily memory latency bound on the MIC. This study suggests that despite low initial porting e_ort, Monte Carlo codes do not naturally lend themselves to the MIC platform — just like to the GPUs, and that the memory latency problem needs to be addressed in order to achieve decent performance gain.

    This study involving 2 grade VIII students was taken place in SMPK Anak Bangsa Surabaya. Subjects were selected using equal mathematics ability criteria. Data was collected using provision of problem-solving tasks and followed by a task-based interview. Obtained data was analysed through the following steps, which are data reduction, data presentation, and conclusions. Meanwhile, to obtain a valid data, in this study, researchers used data triangulation. The results indicated that in the problem number 1 about identifying patterns, the subjects of male and female show a tendency of similarities in stating what is known and asked the question. However, the male students provided a more specific answer in explaining the magnitude of the difference between the first quantity and the increased differences in the other quantities. Related the activities in determining the relationship between two quantities, male subjects and women subject tended to have similarities in the sense of using trial and error on existing mathematical operations. It can be concluded that the functional way of thinking both subjects is relatively identic. Nevertheless, the male subject showed the more specific answer in finding the difference between the two quantities and finding the correspondence relationship between the quantities.

    Recent reflections by Inge Lehmann on her discovery of the inner core (Eos, January 20, 1987, p. 33; see also Bolt [1987, 1982]) remind us that this outstanding Earth scientist is now in her 100th year. The inner core boundary (ICB) is one of the three great seismic-compositional discontinuities that divide Earth into crust, mantle, core, and inner core. The other two discontinuities are well known by names honoring their discoverers, Andrija Mohorovicic and Beno Gutenberg. In this tradition, it is fitting that the ICB be called the Lehmann Discontinuity in honor of its discoverer.

    In budding yeast and human cells, ING (inhibitor of growth) tumor suppressor proteins play important roles in response to DNA damage by modulating chromatin structure through collaborating with histone acetyltransferase or histone deacetylase complexes. However, the biological functions of ING family proteins in fission yeast are poorly defined. Here, we report that Png1p, a fission yeast ING homolog protein, is required for cell growth under normal and DNA-damaged conditions. Png1p was further confirmed to regulate histone H4 acetylation through collaboration with the MYST family histone acetyltransferase 1 (Mst1). Additionally, both fission yeast PNG1 and MST1 can functionally complement their budding yeast correspondence homologs YNG2 and ESA1, respectively. These results suggest that ING proteins in fission yeast might also conserve function, similar to ING proteins in budding yeast and human cells. We also showed that decreased acetylation in Deltapng1 cells resulted in genome-wide down-regulation of 756 open reading frames, including the central DNA repair gene RAD22. Overexpression of RAD22 partially rescued the png1 mutant phenotype under both normal and DNA-damaged conditions. Furthermore, decreased expression of RAD22 in Deltapng1 cells was confirmed to be caused by decreased H4 acetylation at its promoter. Altogether, these results indicate that Png1p is required for histone H4 acetylation and functions upstream of RAD22 in the DNA damage response pathway.

    To explore the inhibitory effect and anti-cancer mechanisms of adenovirus-mediated ING4 gene on the human bladder cancer T24 cells in vitro. The methods of reverse transcription-polymerase chain reaction (RT-PCR) and Western blot were used to detect the expression of ING4 in human bladder urothelial carcinoma T24 line. The influence of Ad-ING4 transfection on cell proliferation was evaluated by MTT assay and cell apoptosis by Hochest33258 staining and flow cytometry. RT-PCR and Western blot were performed to detect the transcriptional level of such apoptosis-related genes as Bcl-2, Bax, p53, HIF-1α and caspase-3. Human ING4 was successfully transcribed in T24 cell. Apoptosis rate of T24 cell in Ad-ING4 group was significant higher than that in control groups (17.2% ± 4.1% vs 4.7% ± 1.2% and 4.8% ± 1.2%, P T24 human bladder cancer cell and induces in vitro apoptosis. It may be related to the up-regulation of P53 and Bax/Bcl-2, and the down-regulation of HIF-1α. Thus the caspase-3 activation is enhanced so as to lead to apoptosis.

    Full Text Available Until recently, large corpora of Russian had been lacking. This changed with the development of the Russian National Corpus (RNC and the appearance of Integrum, a large commercial database that has shown to be a valuable tool for linguistic studies.             We have used both corpora to study the actual use of recent loanwords in Russian that have their origin in English ‑ing forms, such as rejting (rating and kasting (casting. The RNC was used to compile a list of ‑ing words and their frequency. Integrum provided the data for a qualitative analysis of the semantics and possible developments between 2000 and 2011 of five ‑ing words. We also tried to use the corpora to study the changes in popularity of ‑ing words over time, which was possible to some extent. This corpus-based study of ‑ing words illustrates both possibilities and limitations of the two largest corpora for Russian, RNC and Integrum.

  13. LoopIng: a template-based tool for predicting the structure of protein loops.

    KAUST Repository

    Messih, Mario Abdel

    2015-08-06

    Predicting the structure of protein loops is very challenging, mainly because they are not necessarily subject to strong evolutionary pressure. This implies that, unlike the rest of the protein, standard homology modeling techniques are not very effective in modeling their structure. However, loops are often involved in protein function, hence inferring their structure is important for predicting protein structure as well as function.We describe a method, LoopIng, based on the Random Forest automated learning technique, which, given a target loop, selects a structural template for it from a database of loop candidates. Compared to the most recently available methods, LoopIng is able to achieve similar accuracy for short loops (4-10 residues) and significant enhancements for long loops (11-20 residues). The quality of the predictions is robust to errors that unavoidably affect the stem regions when these are modeled. The method returns a confidence score for the predicted template loops and has the advantage of being very fast (on average: 1 min/loop).www.biocomputing.it/loopinganna.tramontano@uniroma1.itSupplementary data are available at Bioinformatics online.

A positive control group received weekly 100 mg/kg 54lurouracil/leucovorin starting on day 2. ING-1(heMAb/day 2 treatment significantly reduced both the number of visible tumor nodules in body cavities (P < .01 and the number of metastases on lung surfaces (P < .005. The treatment also resulted in a 91% reduction of micrometastases in lung tissues (P <.0001. Delaying ING-1(heMAb treatment until day 5 caused 54% reduction in micrometastases (P <.005. Our results indicate that a number of parameters, including treatment starting day, dose level, and dose frequency, are critical in achieving the optimal efficacy of ING-1(heMAb. We conclude that ING-1(heMAb effectively reduced tumor metastases in a murine cancer model. Immunotherapy with ING-1(heMAb may be beneficial in treating human metastatic diseases.

    Consacré à la sauvegarde des grandes oeuvres de l’ingénierie du XXe siècle, ce premier numéro des Cahiers du TSAM explore le devenir de certaines des plus remarquables et emblématiques structures en béton du siècle passé. A travers les fi gures d’héroïques constructeurs, il interroge l’héritage construit des ingénieurs, convoquant les plus audacieux d’entre eux (Freyssinet, Isler, Maillart, Nervi, Vierendeel, etc.). Alors que la sauvegarde de l’architecture du XXe siècle s’est récemment constituée en discipline à part entière, la préservation des ouvrages de l’ingénierie de cette période est encore balbutiante. Considérés trop souvent sous le seul point de vue de la sécurité ou de la maintenance, ces ouvrages s’avèrent parfois de véritables chefs-d’oeuvre, jalons d’un «art de l’ingénieur» à la frontière entre performance technique et beauté plastique. Ces cahiers sont donc l’occasion d’initier, à l’appui d’exemples et de projets de sauvegarde con...

  5. Cognitive profiles of groups of poor readers and dyslexic children on the British Ability Scales.

    Tyler, S; Elliott, C D

    1988-11-01

    Two samples of children with reading difficulties--145 poor readers and 121 dyslexic children--were tested on the British Ability Scales (BAS). The poor readers were classified, using Rutter & Yule's (1975) criteria, into children with specific reading retardation and general reading backwardness. These children's profiles of scores on the BAS were also entered into a cluster analysis which provided some confirmation of the validity of the Rutter & Yule classification. The BAS scores of the dyslexic children were also entered into a cluster analysis. Three groups were identified: 30 with mixed visuo-spatial and linguistic processing problems, 52 with sequential processing problems, and 39 with problems in the holistic retrieval of information. It was concluded that the data lend support to the view that children with specific reading retardation, and dyslexic children in particular, are not homogeneous in their cognitive profiles. Finally, each group identified above was analysed for fit to the Lawson & Inglis (1985) principal components model of learning disability. The fit to the model for most groups was poor. It was concluded that a model which implicates left hemisphere aetiology for all LD children is inadequate. Some benefit, however, is likely to accrue from the more rigorous definition of specific subtypes, and in this endeavour the BAS appear to offer a useful advance in such assessment and identification.

    Loss of function/dysregulation of inhibitor of growth 4 (ING4) and hyperactivation of NF-κB are frequent events in many types of human malignancies. However, the molecular mechanisms underlying these remarkable aberrations are not understood. Here, we report that ING4 is physically associated with JFK. We demonstrated that JFK targets ING4 for ubiquitination and degradation through assembly of an Skp1-Cul1-F-box (SCF) complex. We showed that JFK-mediated ING4 destabilization leads to the hyperactivation of the canonical NF-κB pathway and promotes angiogenesis and metastasis of breast cancer. Significantly, the expression of JFK is markedly up-regulated in breast cancer, and the level of JFK is negatively correlated with that of ING4 and positively correlated with an aggressive clinical behavior of breast carcinomas. Our study identified SCF(JFK) as a bona fide E3 ligase for ING4 and unraveled the JFK-ING4-NF-κB axis as an important player in the development and progression of breast cancer, supporting the pursuit of JFK as a potential target for breast cancer intervention. © 2015 Yan et al.; Published by Cold Spring Harbor Laboratory Press.

Dr Oen played an important role in five different periods: Dutch colonialism, the Japanese occupation, the Indonesian revolution, Soekarno’s regime, and Suharto’s New Order. Known for being a benevolent doctor, activist, and patriot of the revolution during his life-time, Dr Oen also gave medical assistance to the needy, which famously earned him the accolade of “doctor of the poor”. During the Indonesian revolution, Dr Oen assisted the Student Soldiers (Tentara Pelajar and afterwards was appointed the member of Supreme Advisory Council (Dewan Pertimbangan Agung/DPA by Soekarno in 1949. As a benevolent doctor and activist, Dr Oen is remembered for founding the Panti Kosala Hospital which was renamed to perpetuate his name on 30 October 1983, exactly a year after his passing. When he died, thousands of peoples gathered to pay their final respects to the doctor. He was honoured with a ceremony conducted in the Mangkunegaran Palace. Dr Oen’s name will be eternally respected, especially in Surakarta.

    Full Text Available After the Second World War, Slovene theatres started to include in their repertoires more and more American authors and their plays. Their choice were varied, from serious dramas by Eugene O'Neill, Tennessee Williams and Arthur Miller, to comedies by Norman Krasna and John Van Druten dependant mostly on the availability of the texts. In the immediate postwar years the theatres liked to present playwrights with progressive ideas in their plays, such as Lillian Hellman and her "The Little Foxes", which was successfully produced at three Slovene theatres, while her "The Children's Hour" received negative reviews. In the fifties, three theatres chose two plays by Clifford Odets, "Golden Boy" and "Country Girl", mainly because of his socially critical ideas and his admiration of humanity. His plays were rather well received; however, the critics doubted his literary genius. William Inge and his plays, "Come Back, Little Sheba", "Picnic" and "Bus Stop", chosen mainly because of the warmth with which the author depicted the tragedy and the beauty of life, were produced at three Slovene theatres. The author received rather wide-ranging opinions from the critics. Some thought him to be an unoriginal depicter of dull American life, while others praised his lyricism and new dramatic techniques.

    Dietary K intake plays an important role in the regulation of renal K secretion: a high K intake stimulates whereas low K intake suppresses renal K secretion. Our previous studies demonstrated that the Src family protein-tyrosine kinase and mitogen-activated protein kinase (MAPK) are involved in mediating the effect of low K intake on renal K channels and K secretion. However, the molecular mechanism by which low K intake stimulates MAPK is not completely understood. Here we show that inhibitor of growth 4 (ING4), a protein with a highly conserved plant homeodomain finger motif, is involved in mediating the effect of low K intake on MAPK. K restriction stimulates the expression of ING4 in the kidney and superoxide anions, and its related products are involved in mediating the effect of low K intake on ING4 expression. We used HEK293 cells to express ING4 and observed that expression of ING4 increased the phosphorylation of p38 and ERK MAPK, whereas down-regulation of ING4 with small interfering RNA decreased the phosphorylation of p38 and ERK. Immunocytochemistry showed that ING4 was expressed in the renal outer medullary potassium (ROMK)-positive tubules. Moreover, ING4 decreased K currents in Xenopus oocytes injected with ROMK channel cRNA. This inhibitory effect was reversed by blocking p38 and ERK MAPK. These data provide evidence for the role of ING4 in mediating the effect of low K intake on ROMK channel activity by stimulation of p38 and ERK MAPK.

    Emergency medical services (EMS) personnel are rarely trained in death notification despite frequently terminating resuscitation in the field. As research continues to validate guidelines for the termination of resuscitation (TOR) and reputable organizations such as NAEMSP lend support to such protocols, death notification in the field will continue to increase. We sought to test the hypothesis that a learning module, GRIEV_ING, which teaches a structured method for death notification, will improve the confidence, competency, and communication skills of EMS personnel in death notification. The GRIEV_ING didactic session consisted of a 90-minute education session composed of a didactic lecture, small group breakout session, and role-plays. This was both preceded and followed by a 15-minute case role-play using trained standardized survivors. To assess performance we used a pre-post design with 3 quantitative measures: confidence, competency, and, communication. Paramedics from the local EMS agency participated in the education as a part of continuing education. Pre-post differences were measured using a paired t-test and McNemar's test. Thirty EMS personnel consented and participated. Confidence and competency demonstrated statistically significant improvements: confidence (percent change in scores = 11.4%, p paramedics to use a structured communication model based on the GRIEV_ING mnemonic improved confidence and competence of EMS personnel delivering death notification.

    Full Text Available 【Abstract】 Objectives: Trauma is among the lead- ing causes of death. Medical management of blunt abdomi- nal trauma (BAT relies on judging patients for whom lap- arotomy is mandatory. This study aimed to determine BAT patients’ signs, as well as paraclinical data, and to clarify the accuracy, sensitivity, specificity, positive and negative predictive value of clinical abdominal scoring system (CASS, a new scoring system based on clinical signs, in predicting whether a BAT patient needs laparotomy or not. Methods: Totally 400 patients suspected of BAT that arrived at the emergency department of two university hos- pitals in Tehran from March 20, 2007 to March 19, 2009 were included in this study. They were evaluated for age, sex, type of trauma, systolic blood pressure, Glasgow coma scale (GCS, pulse rate, time of presentation after trauma, abdomi- nal clinical findings, respiratory rate, temperature, hemoglo- bin (Hb concentration, focused abdominal sonography in trauma (FAST and CASS. Results: Our measurements showed that CASS had an accuracy of 94%, sensitivity of 100%, specificity of 88%, positive predictive value of 90% and negative predictive value of 100% in determining the necessity of laparotomy in BAT patients. Moreover, in our analysis, systolic blood pressure, GCS, pulse rate, Hb concentration, time of presen- tation after trauma, abdominal clinical findings and FAST were also shown to be helpful in confirming the need for laparotomy (P<0.05. Conclusion: CASS is a promising scoring system in rapid detection of the need for laparotomy as well as in minimizing auxiliary expense for further evaluation in BAT patients, thus to promote the cost-benefit ratio and accu- racy of diagnosis.

    2013-01-01

    This study assessed the validity, sensitivity, and specificity of the Substance Use Risk Profile Scale (SURPS), a measure of personality risk factors for substance use and other behavioral problems in adolescence. The concurrent and predictive validity of the SURPS was tested in a sample of 1,162 adolescents (mean age: 13.7 years) using linear and logistic regressions, while its sensitivity and specificity were examined using the receiver operating characteristics curve analyses. Concurrent and predictive validity tests showed that all 4 brief scales-hopelessness (H), anxiety sensitivity (AS), impulsivity (IMP), and sensation seeking (SS)-were related, in theoretically expected ways, to measures of substance use and other behavioral and emotional problems. Results also showed that when using the 4 SURPS subscales to identify adolescents "at risk," one can identify a high number of those who developed problems (high sensitivity scores ranging from 72 to 91%). And, as predicted, because each scale is related to specific substance and mental health problems, good specificity was obtained when using the individual personality subscales (e.g., most adolescents identified at high risk by the IMP scale developed conduct or drug use problems within the next 18 months [a high specificity score of 70 to 80%]). The SURPS is a valuable tool for identifying adolescents at high risk for substance misuse and other emotional and behavioral problems. Implications of findings for the use of this measure in future research and prevention interventions are discussed. Copyright © 2012 by the Research Society on Alcoholism.

L’objectif est de dépasser les visions stato-centrées, qui envisagent la construction des grandes infrastructures routières sous l’angle d’un État central équipant et modernisant la France à partir de Paris. La description des évolutions historiques, que nous avons esquissée, montre trois configurations d’acteurs différentes au niveau de l’aménagement routier de la région lyonnaise. Une première période, l’entre-deux guerres, est marquée par le dynamisme local, symbolisé par l’indépendance technique et financière des collectivités locales à travers la figure des ingénieurs en chef des services techniques municipaux et du service vicinal. Puis s’ouvre une phase de rapatriement de ces problématiques dans le giron de l’État dès la fin des années 1930, confirmée après la seconde guerre mondiale, avec une expertise monopolisée par les Ponts et Chaussées. Enfin à partir des années 1980, les enjeux sont de nouveau focalisés au niveau local, mais avec une échelle territoriale et politique différente de celle connue pendant l’entre-deux guerres.The paper deals with the conception and realization of road building plans as a lens to understand changes in local decision-making and the relations between municipalities and the state. My purpose is to go beyond the usual studies of road constructions as a central state decision to equip and modernize France from the capital.

The interwar period relates to a period of municipal dynamism with the financial and technical autonomy of local authorities through the figure of the local engineer.

    2007-06-01

    We regret to announce the death of David Dew-Hughes, the second Honorary Editor of Superconductor Science and Technology, in Autumn 2006. He was born in Manchester, the eldest of three children, attended Manchester Grammar School and took his first degree in metallurgy at Birmingham, before undertaking a Doctorate of Engineering at Yale University. After initial work for IBM on semiconductors, he returned to England as a lecturer in metallurgy at Cambridge University. There he devoted his career to superconductivity long before it became fashionable, starting a group on the properties of what we now know as type II materials, with his students Jan Evetts, Archie Campbell and Anant Narlikar. Between them they paved the way to our understanding of the magnetic vortex properties of these materials, and thus to the development of modern practical materials for superconducting magnets. Eur.Ing. Professor David Dew-Hughes 1932-2006 In 1965 he became a founding Senior Lecturer in physics at Lancaster University, moving to Brookhaven National Laboratory in 1974. His final academic post was in engineering science at Oxford University where he also held a University College Tutorial Fellowship. As long ago as 1971 David wrote an authoritative review for Reports on Progress in Physics on 'The metallurgical enhancement of type II superconductors'. Following the discovery of high-Tc superconductivity, IOP Publishing launched Superconductor Science and Technology in 1988 and he was a founder member of its Editorial Board. When Jan Evetts retired as Honorary Editor in 1992, David was the natural choice as his successor. He served a five year term and remained on the Board as Deputy Editor until the end of 2000. To mark the 10th anniversary of high-temperature superconductivity in 1997, David edited a special issue of Superconductor Science and Technology in which past and present members of the Editorial Board contributed reviews of their specialities. He noted that at that time

    The Message Passing Interface (MPI) is the de facto message-passing standard for massively parallel programs. It is often the case that application performance is a crucial factor, especially for solving grand challenge problems. While there have been many studies on the scalability of applications, there have not been many focusing on the specific types of MPI calls being made and their impact on application performance. Using a profiling tool called mpiP, a large spectrum of parallel scientific applications were surveyed and their performance results analyzed.

    The boundary between weathered rocks and unaffected rocks that was a cause of landslide in the middle hard rock area was studied with application of resistivity image profiling. The surveyed site located at the end of the moderately inclined plateau that also occupied the end of the small ridge facing the alluvial low land along rivers. The geological structure is composed of clayslate, a base rock, covered by volcano extrusive made from puzzolana and loam. The clayslate has been weathered to deep area and easily destroyable. However, the rock structure remained and the unaffected rocks gradually substituted for the weathered rocks with the depth becoming large starting from the surface. The depth and horizontal propagation of the weathered rock area that directly or indirectly causes the landslide was investigated. Using the difference in resistivity between weathered rock and unaffected rock areas as criterion, the data obtained in the site survey were analyzed with computer based on the resistivity image profiling. In this computer analysis, after execution of terrain correction the linear filter method was applied to obtain actual resistivity distribution of soil. As a result of this study, the boundary between weathered rocks and unaffected rocks was identified by the resistivity distribution, and the coverage of the landslide area was also found. 3 refs., 4 figs.

    During the last few years there has been a growing interest in research focused on the metabolism of steroid hormones despite that the study of metabolic hormone pathways is still a difficult and demanding task because of low steroid concentrations and a complexity of the analysed matrices. Thus, there has been an increasing interest in the development of new, more selective and sensitive methods for monitoring these compounds in biological samples. A lot of bibliographic databases for world research literature were structurally searched using selected review question and inclusion/exclusion criteria. Next, the reports of the highest quality were selected using standard tools (181) and they were described to evaluate the advantages and limitations of different approaches in the measurements of the steroids and their metabolites. The overview of the analytical challenges, development of methods used in the assessment of the metabolic pathways of steroid hormones, and the priorities for future research with a special consideration for liquid chromatography (LC) and capillary electrophoresis (CE) techniques have been presented. Moreover, many LC and CE applications in pharmacological and psychological studies as well as endocrinology and sports medicine, taking into account the recent progress in the area of the metabolic profiling of steroids, have been critically discussed. The latest reports show that LC systems coupled with mass spectrometry have the predominant position in the research of steroid profiles. Moreover, CE techniques are going to gain a prominent position in the diagnosis of hormone levels in the near future.

    The compatibility of the semiempirical turbulence theory of L. Prandtl with the actual flow pattern in a turbulent boundary layer is considered in this article, and the final calculation results of the boundary layer is analyzed based on the mentioned theory. It shows that accepted additional conditions and relationships, which integrate the differential equation of L. Prandtl, associating the turbulent stresses in the boundary layer with the transverse velocity gradient, are fulfilled only in the near-wall region where the mentioned equation loses meaning and are inconsistent with the physical meaning on the main part of integration. It is noted that an introduced concept about the presence of a laminar sublayer between the wall and the turbulent boundary layer is the way of making of a physical meaning to the logarithmic velocity profile, and can be defined as adjustment of the actual flow to the formula that is inconsistent with the actual boundary conditions. It shows that coincidence of the experimental data with the actual logarithmic profile is obtained as a result of the use of not particular physical value, as an argument, but function of this value.

  10. Ziploc-ing the structure 2.0: Endoplasmic reticulum-resident peptidyl prolyl isomerases show different activities toward hydroxyproline.

    Extracellular matrix proteins are biosynthesized in the rough endoplasmic reticulum (rER), and the triple-helical protein collagen is the most abundant extracellular matrix component in the human body. Many enzymes, molecular chaperones, and post-translational modifiers facilitate collagen biosynthesis. Collagen contains a large number of proline residues, so the cis/trans isomerization of proline peptide bonds is the rate-limiting step during triple-helix formation. Accordingly, the rER-resident peptidyl prolyl cis/trans isomerases (PPIases) play an important role in the zipper-like triple-helix formation in collagen. We previously described this process as "Ziploc-ing the structure" and now provide additional information on the activity of individual rER PPIases. We investigated the substrate preferences of these PPIases in vitro using type III collagen, the unhydroxylated quarter fragment of type III collagen, and synthetic peptides as substrates. We observed changes in activity of six rER-resident PPIases, cyclophilin B (encoded by the PPIB gene), FKBP13 (FKBP2), FKBP19 (FKBP11), FKBP22 (FKBP14), FKBP23 (FKBP7), and FKBP65 (FKBP10), due to posttranslational modifications of proline residues in the substrate. Cyclophilin B and FKBP13 exhibited much lower activity toward post-translationally modified substrates. In contrast, FKBP19, FKBP22, and FKBP65 showed increased activity toward hydroxyproline-containing peptide substrates. Moreover, FKBP22 showed a hydroxyproline-dependent effect by increasing the amount of refolded type III collagen in vitro and FKBP19 seems to interact with triple helical type I collagen. Therefore, we propose that hydroxyproline modulates the rate of Ziploc-ing of the triple helix of collagen in the rER. © 2017 by The American Society for Biochemistry and Molecular Biology, Inc.

  11. Computed torque control of a free-flying cooperat ing-arm robot

    1989-01-01

    The unified approach to solving free-floating space robot manipulator end-point control problems is presented using a control formulation based on an extension of computed torque. Once the desired end-point accelerations have been specified, the kinematic equations are used with momentum conservation equations to solve for the joint accelerations in any of the robot's possible configurations: fixed base or free-flying with open/closed chain grasp. The joint accelerations can then be used to calculate the arm control torques and internal forces using a recursive order N algorithm. Initial experimental verification of these techniques has been performed using a laboratory model of a two-armed space robot. This fully autonomous spacecraft system experiences the drag-free, zero G characteristics of space in two dimensions through the use of an air cushion support system. Results of these initial experiments are included which validate the correctness of the proposed methodology. The further problem of control in the large where not only the manipulator tip positions but the entire system consisting of base and arms must be controlled is also presented. The availability of a physical testbed has brought a keener insight into the subtleties of the problem at hand.

    Fused deposition of ceramics (FDC) is one of the developing solid freeform fabrication (SFF) techniques. The successful production of high performance ceramics by the FDC process requires that no defects exist in the green parts. However, build defects, such as missing roads, poorly bonded layers or sub-perimeter voids can be encountered in improperly built FDC parts. In this study, a method known as WIP'ing (warm isostatic pressing) was evaluated for its ability to eliminate existing defects in GS44 Si{sub 3}N{sub 4} green FDC parts. Analogous to CIP'ing (cold isostatic pressing), the green FDC parts were rubber bagged and loaded into a pressure chamber filled with water soluble oil at different temperatures, ranging from 30 to 90 deg. C, at pressures of up to 35 MPa. X-Ray radiography results indicated that at temperatures above 70 deg. C, WIP'ing was effective in closing the gaps of the intentionally placed void defects in FDC parts. However, WIP'ing above 70 deg. C was not effective in healing the defects completely. The fracture strengths of FDC parts with intentional added defects, WIP'ed above 70 deg. C were substantially lower than control samples.

    Full Text Available Abstract Background Sarcoidosis is a granulomatous disorder of unknown etiology. The term of immunoangiostasis has been addressed by various studies as potentially involved in the disease pathogenesis. The aim of the study was to investigate the expression of the master regulator of angiogenesis hypoxia inducible factor (HIF-1a – vascular endothelial growth factor (VEGF- inhibitor of growth factor 4-(ING4 - axis within sarcoid granuloma. Methods A total of 37 patients with sarcoidosis stages II-III were recruited in our study. Tissue microarray technology coupled with immunohistochemistry analysis were applied to video-assisted thoracoscopic surgery (VATS lung biopsy samples collected from 37 sarcoidosis patients and 24 controls underwent surgery for benign lesions of the lung. Computerized image analysis was used to quantify immunohistochemistry results. qRT-PCR was used to assess HIF-1a and ING4 expression in 10 sarcoidosis mediastinal lymph node and 10 control lung samples. Results HIF-1a and VEGF-ING4 expression, both in protein and mRNA level, was found to be downregulated and upregulated, respectively, in sarcoidosis samples compared to controls. Immunohistochemistry coupled with computerized image analysis revealed minimal expression of HIF-1a within sarcoid granulomas whereas an abundant staining of ING4 and VEGF in epithelioid cells was also visualized. Conclusions Our data suggest an impairment of the HIF-1a – VEGF axis, potentialy arising by ING4 overexpression and ultimately resulting in angiostasis and monocyte recruitment within granulomas. The concept of immunoangiostasis as a possible protection mechanism against antigens of infectious origin needs further research to be verified.

    Resistance to chemotherapy remains a major challenge in the treatment of human glioblastoma (GBM). Glycogen synthase kinase-3β (GSK-3β), a positive regulator of NF-κB-mediated survival and chemoresistance of cancer cells, has been identified as a potential therapeutic target in human GBM. Our objective was to determine the antitumor effect of GSK-3 inhibitor 9-ING-41 in combination with chemotherapy in patient-derived xenograft (PDX) models of human GBM. We utilized chemoresistant PDX models of GBM, GBM6 and GBM12, to study the effect of 9-ING-41 used alone and in combination with chemotherapy on tumor progression and survival. GBM6 and GBM12 were transfected by reporter constructs to enable bioluminescence imaging, which was used to stage animals prior to treatment and to follow intracranial GBM tumor growth. Immunohistochemical staining, apoptosis assay, and immunoblotting were used to assess the expression of GSK-3β and the effects of treatment in these models. We found that 9-ING-41 significantly enhanced 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea (CCNU) antitumor activity in staged orthotopic GBM12 (no response to CCNU) and GBM6 (partial response to CCNU) PDX models, as indicated by a decrease in tumor bioluminescence in mouse brain and a significant increase in overall survival. Treatment with the combination of CCNU and 9-ING-41 resulted in histologically confirmed cures in these studies. Our results demonstrate that the GSK-3 inhibitor 9-ING-41, a clinical candidate currently in Investigational New Drug (IND)-enabling development, significantly enhances the efficacy of CCNU therapy for human GBM and warrants consideration for clinical evaluation in this difficult-to-treat patient population.

  20. Genetics and language: a neurobiological perspective on the missing link (-ing hypotheses).

    Science.gov (United States)

    Poeppel, David

    2011-12-01

    The paper argues that both evolutionary and genetic approaches to studying the biological foundations of speech and language could benefit from fractionating the problem at a finer grain, aiming not to map genetics to "language"-or even subdomains of language such as "phonology" or "syntax"-but rather to link genetic results to component formal operations that underlie processing the comprehension and production of linguistic representations. Neuroanatomic and neurophysiological research suggests that language processing is broken down in space (distributed functional anatomy along concurrent pathways) and time (concurrent processing on multiple time scales). These parallel neuronal pathways and their local circuits form the infrastructure of speech and language and are the actual targets of evolution/genetics. Therefore, investigating the mapping from gene to brain circuit to linguistic phenotype at the level of generic computational operations (subroutines actually executable in these circuits) stands to provide a new perspective on the biological foundations in the healthy and challenged brain.

    We report the discovery of a young stellar bridge that forms a continuous connection between the Magellanic Clouds. This finding is based on number density maps for stellar populations found in data gathered by OGLE-IV that fully cover over 270 deg2 of the sky in the Magellanic Bridge area. This is the most extensive optical survey of this region to date. We find that the young population is present mainly in the western half of the MBR, which, together with the newly discovered young population in the eastern Bridge, form a continuous stream of stars connecting both galaxies along δ ~ -73.5 deg. The young population distribution is clumped, with one of the major densities close to the SMC and the other fairly isolated and located approximately mid-way between the Clouds, which we call the OGLE island. These overdensities are well matched by H I surface density contours, although the newly found young population in the eastern Bridge is offset by ~2 deg north from the highest H I density contour. We observe a continuity of red clump stars between the Magellanic Clouds which represent an intermediate-age population. Red clump stars are present mainly in the southern and central parts of the Magellanic Bridge, below its gaseous part, and their presence is reflected by a strong deviation from the radial density profiles of the two galaxies. This may indicate either a tidal stream of stars, or that the stellar halos of the two galaxies overlap. On the other hand, we do not observe such an overlap within an intermediate-age population represented by the top of the red giant branch and the asymptotic giant branch stars. We also see only minor mixing of the old populations of the Clouds in the southern part of the Bridge, represented by the lowest part of the red giant branch.

    This report covers a two-year program to develop fully dense Si{sub 3}N{sub 4} matrix SiC whisker composites with enhanced properties over monolithic Si{sub 3}N{sub 4} materials. The primary goal was to develop a composite with a fracture toughness > 10 MPa{radical}m, capable of using high pressure glass encapsulated HIP'ing. Coating methods were developed to apply thin (<150nm) stoichiometric BN layers to SiC whiskers and also to apply a dual coating of SiC over carbon to the whiskers. Fracture toughness of the composites was determined to increase as the quantity of whiskers (or elongated grains) with their axis perpendicular to the crack plane increased. Of the interface compositions evaluated in this effort, carbon was determined to be the most effective for increasing toughness. The highest toughnesses (6.8--7.0 MPa{radical}m) were obtained with uniaxially aligned carbon coated whiskers. There was no evidence of the carbon coating compromising the oxidation resistance of the composites at 1370{degree}C.

    Star-Planet Interaction (SPI) is a broad phenomenological term which encompasses a variety of physical effects relevant for the evolution of extra-solar planetary systems, in particular those hosting giant gas planets in close orbits around their parent star. While theoretical expectations of SPI are abundant, observational signatures are still elusive with current instrumentation and adopted observing strategies. In particular, recent X-ray observations provided intriguing indications of different SPI-driven effects, including enhanced coronal emission and flaring activity related to the phase of the planetary orbit, but for a few specific planet hosting stars, while results based on statistical studies are controversial. I will review the state of the art on the matter, and possible future developments with Athena and SKA that will help us for a better characterization of exoplanets and their abitability conditions.

    In March 1974, Dr.-Ing Ulrich Mueller, then Privatdozent (unestablished university lecturer) at the Institut fuer Stroemungslehre und Stroemungsmaschinen (Institute for Fluid Mechanics and Fluid Kinetic Machines) of Karlsruhe University, was appointed Director of the Institut fuer Reaktorbauelemente (IRB) of the former Gesellschaft fuer Kernforschung (GfK), now called Karlsruhe Research Center. In September 1974, he was appointed additional professor. Since his qualification for lecturing at a university, 24 dissertations and two habilitations have been concluded by students under his scientific guidance and mentorship. The report in hand presents summaries of these scientific publications. The theoretical and experimental publications in the field of fluid dynamics and thermodynamics are of significance to the safety and design of components for nuclear power plants and thermonuclear reactors, relating to both basic research and industrial applications. Recent scientific work in progress now also includes aspects of long-term cooling of reactor core melts, or waste treatment by incineration and wet oxidation. The scientific problems and aspects studied in the publications reveal the constant process of change experienced in scientific research, also reflected by the fact that the Karlsruhe facility has been renamed twice in the course of time, into Karlsruhe Nuclear Research Center (KfK) in 1977, and into Karlsruhe Research Center - Technology and Environment in 1995. Professor Mueller`s institute, too, has been renamed in 1993 in response to developments, into Institut fuer Angewandte Thermo- und Fluiddynamik (IATF). (orig.)

    The aim of this research monograph is to present a general account of the applicability of elliptic variational inequalities to the important class of free boundary problems of obstacle type from a unifying point of view of classical Mathematical Physics.The first part of the volume introduces some obstacle type problems which can be reduced to variational inequalities. Part II presents some of the main aspects of the theory of elliptic variational inequalities, from the abstract hilbertian framework to the smoothness of the variational solution, discussing in general the properties of the free boundary and including some results on the obstacle Plateau problem. The last part examines the application to free boundary problems, namely the lubrication-cavitation problem, the elastoplastic problem, the Signorini (or the boundary obstacle) problem, the dam problem, the continuous casting problem, the electrochemical machining problem and the problem of the flow with wake in a channel past a profile.

    The quaternary compounds RE4Ni2InGe4 (RE = Dy, Ho, Er, and Tm) were obtained as large single crystals in high yields from reactions run in liquid In. The title compounds crystallize in the monoclinic C2/m space group with the Mg(5)Si(6) structure type with lattice parameters a = 15.420(2) A, b = 4.2224(7) A, c = 7.0191(11) A, and beta = 108.589(2) degrees for Dy4Ni2InGe4, a = 15.373(4) A, b = 4.2101(9) A, c = 6.9935(15) A, and beta = 108.600(3) degrees for Ho4Ni2InGe4, a = 15.334(7) A, b = 4.1937(19) A, c = 6.975(3) A, and beta =108.472(7) degrees for Er4Ni2InGe4, and a = 15.253(2) A, b = 4.1747(6) A, c = 6.9460(9) A, and beta = 108.535(2) degrees for Tm4Ni2InGe4. RE4Ni2InGe4 formed in liquid In from a melt that was rich in the rare-earth component. These compounds are polar intermetallic phases with a cationic rare-earth substructure embedded in a transition metal and main group matrix. The rare-earth atoms form a highly condensed network, leading to interatomic distances that are similar to those found in the elemental lanthanides themselves. The Dy and Ho analogues display two maxima in the susceptibility, suggesting antiferromagnetic ordering behavior and an accompanying spin reorientation. The Er analogue shows only one maximum in the susceptibility, and no magnetic ordering was observed for the Tm compound down to 2 K.

    We present analytic solutions to two test problems that can be used to check the hydrodynamic implementation in computer codes designed to calculate the propagation of shocks in spherically convergent geometry. Our analysis is restricted to fluid materials with constant bulk modulus. In the first problem we present the exact initial acceleration and pressure gradient at the outer surface of a sphere subjected to an exponentially decaying pressure of the form P(t) = P{sub 0}e{sup -at}. We show that finely-zoned hydro-code simulations are in good agreement with our analytic solution. In the second problem we discuss the implosions of incompressible spherical fluid shells and we present the radial pressure profile across the shell thickness. We also discuss a semi-analytic solution to the time-evolution of a nearly spherical shell with arbitrary but small initial 3-dimensional (3-D) perturbations on its inner and outer surfaces.

    Full Text Available A lithological and foraminiferal study of newly acquired sediment cores outside the Ingøydjupet (Ingøy Deep trough has been carried out to improve constraints on the last deglacial history in the south-western Barents Sea. Three lithofacies and three foraminiferal facies were identified. The lowermost lithological unit is a diamicton interpreted as glacial till. It contains a low-abundance, ecologically mixed foraminiferal assemblage, presumably resulting from glacial reworking. Above the diamicton, a layer of ice-rafted debris (IRD, likely associated with intensive iceberg production, marks the initial destabilization of the marine-based ice sheet. At this time, ca. 15.6–15.0 Ky B.P., opportunistic foraminiferal species Nonionellina labradorica and Stainforthia spp. reached peak abundance. During the south-western Barents Sea ice-margin retreat, presumably corresponding to the Bølling interstadial, a sequence of glaciomarine laminations was deposited conformably on the layer of IRD. Sedimentation rates were apparently high (estimated about 0.4 cm per year and the foraminiferal fauna was dominated by Elphidium spp. and Cassidulina reniforme, species common for glacier-proximal environments. A hiatus at the top of the deglacial unit is likely linked to the high bottom-current activity associated with a strengthened inflow of Atlantic water masses into the Barents Sea. The uppermost lithological unit is represented by the Holocene marine sandy mud. It contains a high-abundance, high-diversity foraminiferal fauna with common cassidulinids, Cibicides spp., Epistominella pusilla and planktic species.

Several relevant elements are analyzed such as tutoring and coaching of learners, changes in the relationship to time (wasting and finding time, choosing appropriate materials (reference tools or teaching materials. We will argue in favor of a more deliberate implication of didactics so as to better approach open learning situations and self directed learning.

    Thirteen years have passed since the seminal book on knapsack problems by Martello and Toth appeared. On this occasion a former colleague exclaimed back in 1990: "How can you write 250 pages on the knapsack problem?" Indeed, the definition of the knapsack problem is easily understood even by a non-expert who will not suspect the presence of challenging research topics in this area at the first glance. However, in the last decade a large number of research publications contributed new results for the knapsack problem in all areas of interest such as exact algorithms, heuristics and approximation schemes. Moreover, the extension of the knapsack problem to higher dimensions both in the number of constraints and in the num­ ber of knapsacks, as well as the modification of the problem structure concerning the available item set and the objective function, leads to a number of interesting variations of practical relevance which were the subject of intensive research during the last few years. Hence, two years ago ...

  11. Bridging the Digital Divide through Educational Initiatives: Problems and Solutions

    Directory of Open Access Journals (Sweden)

    2002-01-01

    Full Text Available Being on the wrong side of the digital divide limits the life chances of the socially excluded, who have had neither the wherewithal nor the opportunity to obtain highly paid, skilled positions in IT. Irish policy makers see education as the solution to this problem. However, provid-ing institutional support for the socially disadvantaged who wish to avail of third level education in IT poses significant challenges. This paper describes these problems and explains how they were overcome in implementing an undergraduate university programme called the Diploma in Applied Business Computing. This targeted initiative was an unqualified success in that it achieved its primary objectives--academic and social. However, what made it so was the commitment of concerned stakeholders, from members of the executive steering committee who developed and implemented the course, to the lecturers who delivered it, the companies who supported it, and the students who participated in it.

    This book, intended as a practical working guide for students in Engineering, Mathematics, Physics, or any other field where rigorous calculus is needed, includes 450 exercises. Each chapter starts with a summary of the main definitions and results, which is followed by a selection of solved exercises accompanied by brief, illustrative comments. A selection of problems with indicated solutions rounds out each chapter. A final chapter explores problems that are not designed with a single issue in mind but instead call for the combination of a variety of techniques, rounding out the book’s coverage. Though the book’s primary focus is on functions of one real variable, basic ordinary differential equations (separation of variables, linear first order and constant coefficients ODEs) are also discussed. The material is taken from actual written tests that have been delivered at the Engineering School of the University of Genoa. Literally thousands of students have worked on these problems, ensuring their real-...

    Nutrient claims are a commonly used marketing tactic, but the association between claims and nutritional quality of products is unknown. The objective of this study was to examine trends in the proportion of packaged food and beverage purchases with a nutrient claim, whether claims are associated with improved nutritional profile, and whether the proportion of purchases with claims differs by race/ethnicity or socioeconomic status. This cross-sectional study examined nutrient claims on more than 80 million food and beverage purchases from a transaction-level database of 40,000 US households from 2008 to 2012. χ2 Tests were used to examine whether the proportion of purchases with a low/no-content claim changed over time or differed by race/ethnicity or household socioeconomic status. Pooled transactions were examined using t-tests to compare products' nutritional profiles overall and by food and beverage group. Thirteen percent of food and 35% of beverage purchases had a low-content claim. Prevalence of claims among purchases did not change over time. Low-fat claims were most prevalent for both foods and beverages (10% and 19%, respectively), followed by low-calorie (3% and 9%), low-sugar (2% and 8%), and low-sodium (2% for both) claims. Compared to purchases with no claim, purchases with any low-content claim had lower mean energy, total sugar, total fat, and sodium densities. However, the association between particular claim types and specific nutrient densities varied substantially, and purchases featuring a given low-content claim did not necessarily offer better overall nutritional profiles or better profiles for the claimed nutrient, relative to products without claims. In addition, there was substantial heterogeneity in associations between claims and nutrient densities within food and beverage groups. Variations in nutrient density by claim type and food and beverage group suggests that claims may have differential utility for certain foods or nutrients and

    "The war against women" is a systemic process of discrimination that seeks to subjugate women. In this essay, I will critically examine a contemporary paper, published in a well-known psychoanalytic journal, that views the patient through the lens of Bion's "reverie-ing mother" concept. I argue that leaning upon any particular theory to explain an individual's complex psychological disturbance adheres to a reductionistic line of reasoning that falls prey to the genetic fallacy; interpreting psychological phenomena in this way becomes a myopically focused perch that narrows the clinician's range of vision in scanning the field for other features that influenced the patient's symptomatology and suffering. It defies what we know about the reorganizational potential of the developmental trajectory wherein early features undergo significant change over the course of growth. Within the context of the war against women, such a constrained perspective places the onus of responsibility upon the mother, making her the "whipping boy" for her child's difficulties. Within a blink of an eye, she turns into the embodiment of the trope of the "bad mother." The consequence of misusing a way of thinking about the early mother-child relationship has the unfortunate effect of promoting the war in our current zeitgeist.

    Individual anxieties about sexuality remain surprisingly repetitive despite changing public attitudes toward sexuality. This discussion includes case histories which demonstrate the indirect presentation, using nonverbal and physical cues, adopted by some patients who experience difficulty in verbalizing their sexual problems. When seeking contraceptive consultation, the patient must have no conscious or unconscious anxiety about her desire for sexual pleasure without pregnancy and is entitled to assume, when seeking such advice, that the doctor who offers it has no such prejudices either. When the presenting symptom relates to otherwise illogical contraceptive difficulty, or otherwise invites examination of the genitals, one may suspect that the problem may be sexual and too difficult to express in other than the physical language the patient expects the physician to want. For a couple whose sexual life is comfortably confident and provides pleasure, any contraceptive method will serve its purpose of removing the fear of pregnancy. Such a couple may be advised on logical grounds. For the rest, an open-ended comment such as "I wonder what the real worry is" usually leads to the true anxiety. Yet, at this point, the doctor's anxiety often replaces the patient's since the management of psychosomatic disorders is not part of normal medical training. The temptation to send for the partner and advise a program of relearning, or to make referral to a sex therapy clinic which will do likewise, is strong for any busy doctor who has no psychosexual training. Skill in dealing with such common dilemmas in the context of the brief period allotted to each patient cannot be obtained from a short article, but it is worthwhile for a physician, confronted with a patient whose symptoms do not make sense, to ask what the symptom itself may indicate in terms of the unspoken problem at hand. Most family doctors who understand the training of the Institute of Psychosexual Medicine find

    The density profile of an elastic fiber like DNA will change in space and time as ligands associate with it. This observation affords a new direction in single molecule studies provided that density profiles can be measured in space and time. In fact, this is precisely the objective of seismology, where the mathematics of inverse problems have been employed with success. We argue that inverse problems in elastic media can be directly applied to biophysical problems of fiber-ligand association, and demonstrate that robust algorithms exist to perform density reconstruction in the condensed phase.

In this group of pregnants, screening for gestational diabetes was positive while the diagnosis was negative (normal 100 g-oral glucose tolerance test 100 g-OGTT. Nonetheless, the variations in glucose levels observed throughout the day, and confirmed by the glycemic profile (GP, characterized diurnal hyperglycemia, which accounts for maternal risk and adverse perinatal outcome. The description of this group is unique for both the establishment of the diagnosis during gestation and the follow-up of both the mother and the infant. These pregnancies have been erroneously classified as "low risk" and have not been diagnosed or treated. The IB group corresponds to 13.8% of the pregnant women screened in our service. This rate, added to the 7% of pregnancies complicated by diabetes, increase the occurrence of hyperglycemic disorders during gestation to up to 20.0%. In Rudge's group IB: a perinatal mortality rate is 41‰, which is similar to that observed among diabetic pregnant women and 10 times higher than that found among non-diabetics; b the observed placental abnormalities (both morphological and functional differed from those seen in non-diabetic and diabetic pregnant women, indicating an adjustment to maintain functional activities that facilitated the passage of glucose to the fetus and explained fetal macrosomia (53.8% in non-treated pregnancies; c maternal risk for hypertension, obesity and hyperglycemia was high and seemed to reproduce a model of metabolic syndrome, favoring the potential risk for future diabetes; d 10 years after the index-pregnancy, type 2 diabetes was confirmed in 16.7% of the women in group IB.

    Full Text Available Problem solving methods – are an indispensable part of the management and improvement of production. At the turn of decades, with the development of industry, specific techniques have been implemented and refined by the leaders in this field, such as Toyota, GE and Motorola. The foundation of problem solving is to find real root cause of the problem as soon as possible, its understanding and implementation of appropriate solutions that will ensure that the problem does not occur again. This paper provides an overview of methods and techniques to solve problems in the manufactur-ing plant Trelleborg Wheel Systems Sri Lanka, producing pneumatic tires for light agricultural machinery. These tech-niques are implemented as part of the Lean Six Sigma program.

  20. Transposon identification using profile HMMs

    Science.gov (United States)

    2010-01-01

    Background Transposons are "jumping genes" that account for large quantities of repetitive content in genomes. They are known to affect transcriptional regulation in several different ways, and are implicated in many human diseases. Transposons are related to microRNAs and viruses, and many genes, pseudogenes, and gene promoters are derived from transposons or have origins in transposon-induced duplication. Modeling transposon-derived genomic content is difficult because they are poorly conserved. Profile hidden Markov models (profile HMMs), widely used for protein sequence family modeling, are rarely used for modeling DNA sequence families. The algorithm commonly used to estimate the parameters of profile HMMs, Baum-Welch, is prone to prematurely converge to local optima. The DNA domain is especially problematic for the Baum-Welch algorithm, since it has only four letters as opposed to the twenty residues of the amino acid alphabet. Results We demonstrate with a simulation study and with an application to modeling the MIR family of transposons that two recently introduced methods, Conditional Baum-Welch and Dynamic Model Surgery, achieve better estimates of the parameters of profile HMMs across a range of conditions. Conclusions We argue that these new algorithms expand the range of potential applications of profile HMMs to many important DNA sequence family modeling problems, including that of searching for and modeling the virus-like transposons that are found in all known genomes.

    Full Text Available Lorsque le roman de Caroline Clive, Paul Ferroll, fut publié en juillet 1855, la critique ne tarda pas à faire le lien avec Jane Eyre (1847, de Charlotte Brontë. Les premiers à se pencher sur ce roman jugèrent les deux textes dans des termes similaires, les considérant comme choquants, originaux, puissants et audacieux. En renversant les attentes victoriennes dans le champ de la fiction et en transgressant les « règles » imposées aux femmes-écrivains, ces livres étaient, pensait-on, porteurs de qualités « masculines » tour à tour louées et dénigrées. Paul Ferroll fut donc vu comme un héritier de Jane Eyre qui « accentuait la puissance et l’horreur de l’original » (« deepen[ing] the power and horror of the original ». Cette accentuation est particulièrement prégnante dans le choix de Clive comme protagoniste criminel ; à l’instar de Rochester, ce dernier est un héros byronien qui cache un lourd secret au sujet de sa première épouse.

    Full Text Available Background and Design: Skin diseases are among the most prevalent problems in medical practice. Dermatologists have become active, not only in treatment of skin diseases, but also for the cosmetic and surgical procedures. The purpose of this study was to evaluate the profiles of patients visiting outpatient dermatology clinic of an university hospital and a private dermatologist’s office located in Ankara. Material and Method: The study comprised 5952 patients in each group. Age, gender, diagnosis, and the places they live, were all recorded. Results: There were 3778 women and 2174 men with a mean age of 37.8±15.9 years (6 months-81 years in private visit group, and 3570 women and 2382 men with a mean age of 37.9±18.6 years (1-100 years in hospital visit group. The most common cause for visiting dermatologist’s office was acne. It was fungal diseases for hospital visits. Women with fungal disease, alopecia, nail disorders, urticaria, psychocutaneous dermatoses, bacterial infections, and men with fungal disease, acne, alopecia, urticaria, nail disorders, preferred hospitals over private offices. Both women and men with benign and malignant tumors, nevi, pigmentation disorders, preferred private office over hospital. Men with syphilis, genital herpes, anogenital verruca preferred mainly private offices. Visits to dermatologist’s office for cosmetic procedures constituted only 4% of overall visits.Conclusion: Our finding underscores the fact that medical or clinical dermatology continues to be the focus of most dermatology practices. Apart from cosmetic procedures, the main difference between patient profiles visiting private offices and hospitals is observed in sexually transmitted diseases. (Turkderm 2008; 42: 82-6

    2011-01-01

    Men's health concerns have evolved from the traditional andrology and male sexual health to a more holistic approach that encompasses male psychological, social and physical health. The poor state of health in men compared to their female counterparts is well documented. A review of the epidemiological data from Malaysia noted a similar trend in which men die at higher rates in under 1 and above 15 years old groups and most disease categories compared to women. In Malaysia, the main causes of death in men are non-communicable diseases and injuries. Risk factors, such as risk-taking behaviour, smoking and hypertension, are prevalent and amenable to early interventions. Erectile dysfunction, premature ejaculation and prostate disorders are also prevalent. However, many of these morbidities go unreported and are not diagnosed early; therefore, opportunities for early intervention are missed. This reflects poor health knowledge and inadequate health-care utilisation among Malaysian men. Their health-seeking behaviour has been shown to be strongly influenced by family members and friends. However, more research is needed to identify men's unmet health-care needs and to develop optimal strategies for addressing them. Because the Malaysian population is aging and there is an increase in sedentary lifestyles, optimizing men's health will remain a challenge unless effective measures are implemented. The existing male-unfriendly health-care system and the negative influence of masculinity on men's health behaviour must be addressed. A national men's health policy based on a male-friendly approach to health-care delivery is urgently needed to provide a framework for addressing these challenges. PMID:21358664

    Energy Technology Data Exchange (ETDEWEB)

    Hendon, Raymond C. [Los Alamos National Laboratory; Ramsey, Scott D. [Los Alamos National Laboratory

    2012-08-22

    As an extension of the works of Coggeshall and Ramsey, a class of analytic solutions to the radiation hydrodynamics equations is derived for code verification purposes. These solutions are valid under assumptions including diffusive radiation transport, a polytropic gas equation of state, constant conductivity, separable flow velocity proportional to the curvilinear radial coordinate, and divergence-free heat flux. In accordance with these assumptions, the derived solution class is mathematically invariant with respect to the presence of radiative heat conduction, and thus represents a solution to the compressible flow (Euler) equations with or without conduction terms included. With this solution class, a quantitative code verification study (using spatial convergence rates) is performed for the cell-centered, finite volume, Eulerian compressible flow code xRAGE developed at Los Alamos National Laboratory. Simulation results show near second order spatial convergence in all physical variables when using the hydrodynamics solver only, consistent with that solver's underlying order of accuracy. However, contrary to the mathematical properties of the solution class, when heat conduction algorithms are enabled the calculation does not converge to the analytic solution.

    The hydrodynamics challenge problem represents a classical HPC physics problem, namely high deformation event modeling via Lagrangian shock hydrodynamics. This challenge problem solves the Sedov blast wave problem for one material in three dimensions. The problem has an analytic solution, and can be scaled to arbitrarily large problem sizes. The reference code is drawn from a production LLNL hydrodynamics code.

  11. The landslide problem

    Directory of Open Access Journals (Sweden)

    2015-04-01

    Full Text Available The synonymous use of the general term “landslide”, with a built-in reference to a sliding motion, for all varieties of mass-transport deposits (MTD, which include slides, slumps, debrites, topples, creeps, debris avalanches etc. in subaerial, sublacustrine, submarine, and extraterrestrial environments has created a multitude of conceptual and nomenclatural problems. In addition, concepts of triggers and long-runout mechanisms of mass movements are loosely applied without rigor. These problems have enormous implications for studies in process sedimentology, sequence stratigraphy, palaeogeography, petroleum geology, and engineering geology. Therefore, the objective of this critical review is to identify key problems and to provide conceptual clarity and possible solutions. Specific issues are the following: (1 According to “limit equilibrium analyses” in soil mechanics, sediment failure with a sliding motion is initiated over a shear surface when the factor of safety for slope stability (F is less than 1. However, the term landslide is not meaningful for debris flows with a flowing motion. (2 Sliding motion can be measured in oriented core and outcrop, but such measurement is not practical on seismic profiles or radar images. (3 Although 79 MTD types exist in the geological and engineering literature, only slides, slumps, and debrites are viable depositional facies for interpreting ancient stratigraphic records. (4 The use of the term landslide for highvelocity debris avalanches is inappropriate because velocities of mass-transport processes cannot be determined in the rock record. (5 Of the 21 potential triggering mechanisms of sediment failures, frequent short-term events that last for only a few minutes to several hours or days (e.g., earthquakes, meteorite impacts, tsunamis, tropical cyclones, etc. are more relevant in controlling deposition of deep-water sands than sporadic long-term events that last for thousands to millions of

    Full Text Available Nenhum estudo de peixes e parasitos foi realizado, até o momento, no Lago do Parque do Ingá que sofre influências antrópicas desde seu represamento, em 1970. Este trabalho analisou alguns aspectos ecológicos dos parasitos metazoários dos peixes deste lago. Dos peixes analisados, (69,5% estavam parasitados por pelo menos uma espécie de parasito. Foram encontrados 1.372 parasitos pertencentes à Nematoda (larvas e Platyhelminthes (Monogenea e Cestoda, sendo estes os mais prevalentes e numerosos. O encontro de larvas decestóides em Tilapia rendalli e Oreochromis niloticus confirma a importância destas espécies como participantes de níveis tróficos intermediários. A maior abundância de T. rendalli e O. niloticus,no local, pode ser um fator determinante no recrutamento de parasitos. O parasito aproveita-se das espécies de hospedeiros mais abundantes para garantir o desenvolvimento de seu ciclo de vida e também por serem os mais disponíveis à predação pelas aves piscívorasali presentes, o que torna o local de grande importância para a sustentação do ciclo de vida desses parasitos. A baixa diversidade de endoparasitos coletados pode ser justificada pela presença de metais pesados – Cu e Pb – no sedimento, o que deve estar interferindo nodesenvolvimento dos invertebrados, possíveis hospedeiros intermediários.Ingá lake was dammed in 1970 and, since then, no study on fish and parasites had been done, but it has suffered anthropic influences.

    Written in Python, PROFILER analyzes the radial surface brightness profiles of galaxies. It accurately models a wide range of galaxies and galaxy components, such as elliptical galaxies, the bulges of spiral and lenticular galaxies, nuclear sources, discs, bars, rings, and spiral arms with a variety of parametric functions routinely employed in the field (Sérsic, core-Sérsic, exponential, Gaussian, Moffat and Ferrers). In addition, Profiler can employ the broken exponential model (relevant for disc truncations or antitruncations) and two special cases of the edge-on disc model: namely along the major axis (in the disc plane) and along the minor axis (perpendicular to the disc plane).

  18. Problems of Turkish Librarianship and Problems for Solution

    Directory of Open Access Journals (Sweden)

    1993-09-01

    Full Text Available Report presented to the Librarianship, Documentation and Archives Committee of the UNESCO Turkish National Commission, identifies environmental factors, the notion of library and librarianship in the society, and the low profile of librarians as main sources of problems. The society still sees the librarian as the protector of books. The value given to the profession is, thus, limited to such a narrow understanding of the profession, which leads to low payment and insufficient resource allocation to the libraries. Main field of activity, that is, the pro\\ision of information is expected from documentation and information centres. Library and information work cannot be separated from each other. The proposals for solution of the problems include improvement of professional education, legal provisions, and reorganiztion of professional organizations.

    Hilts, Darolyn; Moore, James M

    2003-09-01

    The present study examined the base rates of normal range Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) profiles in an inpatient sample and examined the differences between adolescents with apparently valid normal range profiles (all clinical scale T-scores MMPI-A validity scale scores and other indexes of underreporting. Normal range profiles cannot be adequately explained by a less pathological history prior to hospitalization or by defensiveness. Thirty percent of male and 25% of female adolescents produced valid MMPI-A profiles in which none of the clinical scales were elevated. Both male and female adolescents with normal range profiles were generally less likely to report internalizing symptoms than those with elevated profiles, but both groups report externalizing symptoms. Neither the standard MMPI-A validity scales nor additional validity scales discriminated between profile groups. Clinicians should not assume that normal range profiles indicate an absence of problems.

  5. New high order FDTD method to solve EMC problems

    Directory of Open Access Journals (Sweden)

    N. Deymier

    2015-10-01

    Full Text Available In electromagnetic compatibility (EMC context, we are interested in developing new ac- curate methods to solve efficiently and accurately Maxwell’s equations in the time domain. Indeed, usual methods such as FDTD or FVTD present im- portant dissipative and/or dispersive errors which prevent to obtain a good numerical approximation of the physical solution for a given industrial scene unless we use a mesh with a very small cell size. To avoid this problem, schemes like the Discontinuous Galerkin (DG method, based on higher order spa- tial approximations, have been introduced and stud- ied on unstructured meshes. However the cost of this kind of method can become prohibitive accord- ing to the mesh used. In this paper, we first present a higher order spatial approximation method on carte- sian meshes. It is based on a finite element ap- proach and recovers at the order 1 the well-known Yee’s schema. Next, to deal with EMC problem, a non-oriented thin wire formalism is proposed for this method. Finally, several examples are given to present the benefits of this new method by compar- ison with both Yee’s schema and DG approaches.

  10. Developing the CUAHSI Metadata Profile

    Science.gov (United States)

    Piasecki, M.; Bermudez, L.; Islam, S.; Beran, B.

    2004-12-01

    The Hydrologic Information System (HIS), of the Consortium of Universities for the Advancement of Hydrologic Science Inc., (CUAHSI), has as one of its goals to improve access to large volume, high quality, and heterogeneous hydrologic data sets. This will be attained in part by adopting a community metadata profile to achieve consistent descriptions that will facilitate data discovery. However, common standards are quite general in nature and typically lack domain specific vocabularies, complicating the adoption of standards for specific communities. We will show and demonstrate the problems encountered in the process of adopting ISO standards to create a CUAHSI metadata profile. The final schema is expressed in a simple metadata format, Metadata Template File (MTF), to leverage metadata annotations/viewer tools already developed by the San Diego Super Computer Center. The steps performed to create an MTF starting from ISO 19115:2003 are the following: 1) creation of ontologies using the Web Ontology Language (OWL) for ISO:19115 2003 and related ISO/TC 211 documents; 2) conceptualization in OWL of related hydrologic vocabularies such as NASA's Global Change Master Directory and units from the Hydrologic Handbook; 3) definition of CUAHSI profile by importing and extending the previous ontologies; 4) explicit creation of CUAHSI core set 5) export of the core set to MTF); 6) definition of metadata blocks for arbitrary digital objects (e.g. time series vs static-spatial data) using ISO's methodology for feature cataloguing; and 7) export of metadata blocks to MTF.

  11. Origins of the physical profile.

    Science.gov (United States)

    Marble, Sanders

    2013-08-01

    This article examines how the U.S. Army came to adopt the physical profile. In 1945, the Army adopted the physical profile system that has, with some changes, survived to this day. Although the profile system does not always work smoothly, it replaced a system that was failing completely to deliver physically fit men to combat units. The World War II problems were the outgrowth of two World War I systems that had been adopted to speed mobilization by (1) accepting physically substandard men and (2) matching men to a noncombat job by their skills. By simply identifying a soldier as "General Service" or "Limited Service" it did not provide enough information about his limitations. In addition, the Army used an intelligence test to grade manpower, but because it lacked information on a man's physical abilities/limitations, that data were misused to allot manpower. These policies interacted with a societal disdain for the "handicapped" and "substandard" and made it hard to use Limited Service men. Adding detail to the information on physical abilities was the Army's solution. Reprint & Copyright © 2013 Association of Military Surgeons of the U.S.

    Juan Antonio Moreno Murcia

    2007-06-01

    Full Text Available The aim of this study was to examine the relationship between motivational characteristics and dispositional flow. In order to accomplish this goal, motivational profiles emerging from key constructs within Achievement Goal Theory and Self-Determination Theory were related to the dispositional flow measures. A sample of 413 young athletes (Age range 12 to 16 years completed the PMCSQ-2, POSQ, SMS and DFS measures. Cluster analysis results revealed three profiles: a "self-determined profile" characterised by higher scores on the task-involving climate perception and on the task orientation; a "non-self-determined profile", characterised by higher scores on ego-involving climate perception and ego orientation; and a "low self-determined and low non-self-determined profile" which had the lowest dispositional flow. No meaningful differences were found between the "self-determined profile" and the "non-self-determined profile" in dispositional flow. The "self-determined profile" was more commonly associated with females, athletes practising individual sports and those training more than three days a week. The "non-self-determined profile" was more customary of males and athletes practising team sports as well as those training just two or three days a week

  4. Genetic Correlation and Gene–Environment Interaction Between Alcohol Problems and Educational Level in Young Adulthood*

    Latvala, Antti; Dick, Danielle M.; Tuulio-Henriksson, Annamari; Suvisaari, Jaana; Viken, Richard J.; Rose, Richard J.; Kaprio, Jaakko

    2011-01-01

    Objective: A lower level of education often co-occurs with alcohol problems, but factors underlying this co-occurrence are not well understood. Specifically, whether these outcomes share part of their underlying genetic influences has not been widely studied. Educational level also reflects various environmental influences that may moderate the genetic etiology of alcohol problems, but gene–environment interactions between educational attainment and alcohol problems are unknown. Method: We studied the two nonmutually exclusive possibilities of common genetic influences and gene–environment interaction between alcohol problems and low education using a population-based sample (n = 4,858) of Finnish young adult twins (Mage = 24.5 years, range: 22.8–28.6 years). Alcohol problems were assessed with the Rutgers Alcohol Problem Index and self-reported maximum number of drinks consumed in a 24-hour period. Years of education, based on completed and ongo-ing studies, represented educational level. Results: Educational level was inversely associated with alcohol problems in young adulthood, and this association was most parsimoniously explained by overlapping genetic influences. Independent of this co-occurrence, higher education was associated with increased relative importance of genetic influences on alcohol problems, whereas environmental factors had a greater effect among twins with lower education. Conclusions: Our findings suggest a complex relationship between educational level and alcohol problems in young adulthood. Lower education is related to higher levels of alcohol problems, and this co-occurrence is influenced by genetic factors affecting both phenotypes. In addition, educational level moderates the importance of genetic and environmental influences on alcohol problems, possibly reflecting differences in social-control mechanisms related to educational level.

    We consider self-similar solutions to the gas dynamics equations. One such solution - a spherical geometry Gaussian density profile - has been analyzed in the existing literature, and a connection between it, a linear velocity profile, and a uniform specific internal energy profile has been identified. In this work, we assume the linear velocity profile to construct an entire class of self-similar sol utions in both cylindrical and spherical geometry, of which the Gaussian form is one possible member. After completing the derivation, we present some results in the context of a test problem for compressible flow codes.

  20. A Non-anthropic Solution to the Cosmological Constant Problem

    Directory of Open Access Journals (Sweden)

    Spivey R. J.

    2016-01-01

    Full Text Available Accelerating cosmological expansion is driven by a minuscule vacuum energy density possibly seeking opportunities to decay to a true ground state. Quasar characteristics imply their central engines possess an intrinsic magnetic field compatible with the pres- ence of an electrically charged toroidal dark hole, an eternally collapsing structure lack- ing an event horizon. The possibility is consistent with the inability of black holes to capture particles in a universe of finite age, Einstein’s dismissal of the Schwarzschild metric as unphysical and the implausibility of the various paradoxes invoked by black hole existence. The uncloaked innards of these dark holes would expose immense vac- uum accelerations at their cores, inevitably tempered by Planck scale physics. The Unruh effect predicts that intense yet highly localised heating should occur there. As thermal energy gradually amasses and dissipates, radiation would eventually start to escape into the surrounding environment. Virtual from the d ark hole perspective, the emissions could not decrease the dark hole’s mass: the energy source must instead be the universal vacuum, the likely repository of dark energy. In analogy with core- collapse supernovae, neutrinos should dominate the cooling flows. Red-shifting to low energies upon escape, quantum degenerate haloes should for m predominantly around the largest galaxies. This mechanism is promising from the perspective of enabling the future universe to efficiently sustain aquatic life before stars become scarce, offering a biological yet decidedly non-anthropic solution to the cosmological constant problem.

    2015-06-01

    This study reviewed prevalence of patients with lower limb amputations with above normal weight profile, with body mass index over 25, in seven disablement services centres managing their amputee rehabilitation in the United Kingdom. To review two clinical standards of practice in amputee rehabilitation. Ambulant lower limb amputees should have their body weight recorded on an electronic information system, with identification of cohort with body weight >100 kg. Lower limb amputees to be provided with suitable weight-rated prosthesis. Observational study of clinical practice. Data were collected from the Clinical Information Management Systems. Inclusion criteria--subjects were ambulant prosthetic users with some prosthetic intervention in the last 5 years and had at least one lower limb amputation. In 96% of patients, the weight record profile was maintained. In addition, 86% were under 100 kg, which is the most common weight limit of prosthetic componentry. Of 15,204 amputation levels, there were 1830 transfemoral and transtibial sites in users with body weight over 100 kg. In 60 cases, the prosthetic limb build was rated to be below the user body weight. In 96% of our patients, body weight was documented, and in 97%, the prosthetic limb builds were within stated body weight limits, but this may not be the case in all the other disablement services centres in the United Kingdom. Also, the incidence of obesity in the United Kingdom is a growing problem, and the health issues associated with obesity are further compounded in the amputee population. Prosthetic componentry has distinct weight limits which must be considered during prescription. As people with amputation approach the limits of specific components, clinicians are faced with the challenge of continued provision in a safe and suitable manner. This article reviews the amputee population and the current national profile to consider trends in provision and the incidence of these challenges. © The

    1996-12-31

    As more information becomes available electronically, tools for finding information of interest to users becomes increasingly important. The goal of the research described here is to build a system for generating comprehensible user profiles that accurately capture user interest with minimum user interaction. The research described here focuses on the importance of a suitable generalization hierarchy and representation for learning profiles which are predictively accurate and comprehensible. In our experiments we evaluated both traditional features based on weighted term vectors as well as subject features corresponding to categories which could be drawn from a thesaurus. Our experiments, conducted in the context of a content-based profiling system for on-line newspapers on the World Wide Web (the IDD News Browser), demonstrate the importance of a generalization hierarchy and the promise of combining natural language processing techniques with machine learning (ML) to address an information retrieval (ER) problem.

  15. Essentialism i religionsundervisningen, ett religionsdidaktiskt problem

    Directory of Open Access Journals (Sweden)

    Torsten Hylén

    2012-12-01

    Full Text Available Essentialist concepts of religion are common in the teaching of religion in schools and to a certain extent also in the academic discipline of religious studies. In this article, a num¬ber of problems with essentialist perceptions of religion are discussed. In the first part of the article a thesis is maintained, according to which essentialist conceptions of religion or spe-cific religions are too limited to be of value in the teaching of religion. This is done through exam¬ples of essentialist expressions on religion. The examples are grouped according to a typol¬ogy of different kinds of essentialism. Two main categories, each with two sub-categories are identified. Thus, the category of essentialism regarding the substance of religion is divided into transcendental or theological essentialism (which presupposes the existence of a sacred power of some kind, the experience of which is the basis for religion, and core essentialism (where it is presupposed that certain ideas or concepts constitute religion as a general category or specific religions. Likewise, the category of essentialism regarding the function of religion has two sub-categories: positive and negative essentialism. These kinds of essentialism presup¬pose that religion or specific religions are inherently good or harmful respectively to human be¬ings. Examples from each of these categories are given and discussed. In the second part of the arti¬cle, Benson Saler’s open concept of religion is presented as an alternative to essentialist or bounded perceptions. It is based on Ludwig Wittgenstein’s idea of family resemblances and on proto-type theory. In connection with this, it is argued that a certain kind of conscious ethnocen¬trism is needed as a point of departure in the study and teaching of religion. The metaphor of educa¬tion as a journey from the familiar out into the unfamiliar and back again is suggested as a possible pattern for such teaching. Finally, some

  17. Psychological profile of laryngectomized patients

    Directory of Open Access Journals (Sweden)

    Bogdan Popescu

    2016-04-01

    Full Text Available Larynx cancer is one of the most susceptible form of cancer susceptible to induce alteration of the patient’s psychological profile due to the social role that the larynx has in communication. Oral communication is severely impaired even after voice rehabilitation of the laryngectomized patients, so that the social rehabilitation is somewhat not only a medical but also a social problem. The psychological profile of these patients is altered in a way that dealing with the disease is sometimes neglected and the interaction with the outside world in terms of oral communication is totally abandoned. The starting point for depression in these cases is the acknowledgement of the disease and is, in some cases, the entire medical environment. Facial scarring, the inability to verbally interact with other human, as well as the presence of the tracheostoma, are all deciding factors in the presence of a low self-esteem for these particular patients. Psychological counseling is a mandatory approach for laryngectomized patients, in order to improve their ability to cope with cancer and providing better recovery chances.

    The multiple-input multiple-output interference channel is considered with perfect channel information at the transmitters and single-user decoding receivers. With all transmissions restricted to single stream beamforming, we consider the problem of finding all Pareto optimal rate-tuples in the achievable rate region. The problem is cast as a rate profile optimization problem. Due to its nonconvexity, we resort to an alternating approach: For fixed receivers, optimal transmission is known. Fo...

    Pan, Feng [Los Alamos National Laboratory; Kasiviswanathan, Shiva [Los Alamos National Laboratory

    2010-01-01

    In the matrix interdiction problem, a real-valued matrix and an integer k is given. The objective is to remove k columns such that the sum over all rows of the maximum entry in each row is minimized. This combinatorial problem is closely related to bipartite network interdiction problem which can be applied to prioritize the border checkpoints in order to minimize the probability that an adversary can successfully cross the border. After introducing the matrix interdiction problem, we will prove the problem is NP-hard, and even NP-hard to approximate with an additive n{gamma} factor for a fixed constant {gamma}. We also present an algorithm for this problem that achieves a factor of (n-k) mUltiplicative approximation ratio.

    This memo catalogs a number of known TCP implementation problems. The goal in doing so is to improve conditions in the existing Internet by enhancing the quality of current TCP/IP implementations. It is hoped that both performance and correctness issues can be resolved by making implementors aware of the problems and their solutions. In the long term, it is hoped that this will provide a reduction in unnecessary traffic on the network, the rate of connection failures due to protocol errors, and load on network servers due to time spent processing both unsuccessful connections and retransmitted data. This will help to ensure the stability of the global Internet. Each problem is defined as follows: Name of Problem The name associated with the problem. In this memo, the name is given as a subsection heading. Classification one or more problem categories for which the problem is classified: "congestion control", "performance", "reliability", "resource management". Description A definition of the problem, succinct but including necessary background material. Significance A brief summary of the sorts of environments for which the problem is significant.

  9. Art as metontological problem

    Directory of Open Access Journals (Sweden)

    Radovanović Saša Ž.

    2014-01-01

    Full Text Available The author explains the link between fundamental ontology and metontology in Heidegger's thought. In this context, he raises the question about art as a metontological problem. Then he goes to show that the problem of metontology stems from imanent transformation of fundamental ontology. In this sense, two aspects of the problem of existence assume relevance, namely, universality and radicalism. He draws the conclusion that metontology and art as its problem, as opposed to fundamental ontology, were not integrated into Heidegger's later thought.

Numerous studies have claimed that master Ju-Lun Wu was one of the key figures, before he inaugurated the vice-chancellor of Imperial Capital University, who inspected Japanese education over 4 months. He inquired into the development and problems of Japanese education by inspecting schools and universities; discussing with scholars, educators, and officials; listening to lectures; and collecting materials. His findings were reported to Minister Pai-Shi Chang and related staff and his Collected Records of Visiting Japan was published. Although his book became a reference book, this study found that Ju-Lun Wu was not directly involved in drafting school systems for several reasons. Therefore, the 1904 Kuei-mao system remains an uncritical, imitated Japanese school system.

    2015-09-01

    Preliminary research has indicated that general facets of metacognition are associated with problem gambling. In the present study we aimed to investigate whether specific facets of metacognition play a role in explaining gambling initiation and perseveration in individuals presenting with gambling disorder. To investigate: (1) the presence of metacognitive beliefs about gambling; (2) the goal of gambling, and its start and stop signals; and (3) the perceived impact of gambling on self-consciousness. Ten individuals with a diagnosis of gambling disorder were assessed using metacognitive profiling, a semi-structured interview. Findings indicated that all participants endorsed both positive and negative metacognitive beliefs about gambling. The primary goal of gambling was to relieve economic hardship and improve cognitive-emotional state. All participants reported that they did not know when this goal was achieved. Start signals for gambling included the ideas and feelings that gambling could solve problems and sensations that it might be the right time to win. The stop signal for gambling, for all participants, was running out of money. All participants also reported a perceived reduction in self-consciousness during a gambling episode. These findings provide preliminary evidence that specific facets of metacognition play a role in gambling disorder.

    This report covers a two-year program to develop fully dense Si{sub 3}N{sub 4} matrix SiC whisker composites with enhanced properties over monolithic Si{sub 3}N{sub 4} materials. The primary goal was to develop a composite with a fracture toughness > 10 MPa{radical}m, capable of using high pressure glass encapsulated HIP`ing. Coating methods were developed to apply thin (<150nm) stoichiometric BN layers to SiC whiskers and also to apply a dual coating of SiC over carbon to the whiskers. Fracture toughness of the composites was determined to increase as the quantity of whiskers (or elongated grains) with their axis perpendicular to the crack plane increased. Of the interface compositions evaluated in this effort, carbon was determined to be the most effective for increasing toughness. The highest toughnesses (6.8--7.0 MPa{radical}m) were obtained with uniaxially aligned carbon coated whiskers. There was no evidence of the carbon coating compromising the oxidation resistance of the composites at 1370{degree}C.

    Objectives To examine the efficacy of self-report and parental report of adolescent sleep problems and compare these findings to the incidence of adolescents who fulfill clinical criteria for a sleep problem. Sleep and daytime functioning factors that predict adolescents’ self-identification of a sleep problem will also be examined. Method 308 adolescents (aged 13–17 years) from eight socioeconomically diverse South Australian high schools participated in this study. Participants completed a survey battery during class time, followed by a 7-day Sleep Diary and the Flinders Fatigue Scale completed on the final day of the study. Parents completed a Sleep, Medical, Education and Family History Survey. Results The percentage of adolescents fulfilling one or more of the criteria for a sleep problem was inordinately high at 66%. Adolescent self-reporting a sleep problem was significantly lower than the adolescents who had one or more of the clinical criteria for a sleep problem (23.1% vs. 66.6%; χ2 = 17.46, padolescent having a sleep problem was significantly lower than adolescent self-report (14.3% vs. 21.1%, pAdolescents who reported unrefreshing sleep were 4.81 times more likely to report a sleep problem. For every hour that bedtime was delayed, the odds of self-reporting a sleep problem increased by 1.91 times, while each additional 10 minutes taken to fall asleep increased the odds 1.40 times. Conclusion While many adolescents were found to have sleep patterns indicative of a sleep problem, only a third of this number self-identify having a sleep problem, while only a sixth of this number are indicated by parental report. This study highlights important features to target in future sleep education and intervention strategies for both adolescents and parents. PMID:24086501

    Full Text Available The classical Multiple Traveling Salesmen Problem is a well-studied optimization problem. Given a set of n goals/targets and m agents, the objective is to find m round trips, such that each target is visited only once and by only one agent, and the total distance of these round trips is minimal. In this paper we describe the Multiagent Planning Problem, a variant of the classical Multiple Traveling Salesmen Problem: given a set of n goals/targets and a team of m agents, m subtours (simple paths are sought such that each target is visited only once and by only one agent. We optimize for minimum time rather than minimum total distance; therefore the objective is to find the Team Plan in which the longest subtour is as short as possible (a min–max problem. We propose an easy to implement Genetic Algorithm Inspired Descent (GAID method which evolves a set of subtours using genetic operators. We benchmarked GAID against other evolutionary algorithms and heuristics. GAID outperformed the Ant Colony Optimization and the Modified Genetic Algorithm. Even though the heuristics specifically developed for Multiple Traveling Salesmen Problem (e.g., k-split, bisection outperformed GAID, these methods cannot solve the Multiagent Planning Problem. GAID proved to be much better than an open-source Matlab Multiple Traveling Salesmen Problem solver.

    Country Profile: Hungary has been prepared as a background document for use by US Government agencies and US businesses interested in becoming involved with the new democracies of Eastern Europe as they pursue sustainable economic development. The focus of the Profile is on energy and highlights information on Hungary's energy supply, demand, and utilization. It identifies patterns of energy usage in the important economic sectors, especially industry, and provides a preliminary assessment for opportunities to improve efficiencies in energy production, distribution and use by introducing more efficient technologies. The use of more efficient technologies would have the added benefit of reducing the environmental impact which, although is not the focus of the report, is an issue that effects energy choices. The Profile also presents considerable economic information, primarily in the context of how economic restructuring may affect energy supply, demand, and the introduction of more efficient technologies.

  13. Detonation Wave Profile

    Menikoff, Ralph [Los Alamos National Laboratory

    2015-12-14

    The Zel’dovich-von Neumann-Doering (ZND) profile of a detonation wave is derived. Two basic assumptions are required: i. An equation of state (EOS) for a partly burned explosive; P(V, e, λ). ii. A burn rate for the reaction progress variable; d/dt λ = R(V, e, λ). For a steady planar detonation wave the reactive flow PDEs can be reduced to ODEs. The detonation wave profile can be determined from an ODE plus algebraic equations for points on the partly burned detonation loci with a specified wave speed. Furthermore, for the CJ detonation speed the end of the reaction zone is sonic. A solution to the reactive flow equations can be constructed with a rarefaction wave following the detonation wave profile. This corresponds to an underdriven detonation wave, and the rarefaction is know as a Taylor wave.

    Chotewutmontri, Prakitchai; Stiffler, Nicholas; Watkins, Kenneth P; Barkan, Alice

    2018-01-01

    Ribosome profiling (also known as Ribo-seq) provides a genome-wide, high-resolution, and quantitative accounting of mRNA segments that are occupied by ribosomes in vivo. The method has been used to address numerous questions in bacteria, yeast, and metazoa, but its application to questions in plant biology is just beginning. This chapter provides a detailed protocol for profiling ribosomes in plant leaf tissue. The method was developed and optimized with maize, but it has been used successfully with Arabidopsis and tobacco as well. The method captures ribosome footprints from the chloroplast and cytosol in the same preparation, but it is not optimal for detecting the footprints of mitochondrial ribosomes. The protocol is robust and simpler than many of the methods reported previously for ribosome profiling in plants.

    2016-01-01

    One finding of cognitive research is that people do not automatically acquire usable knowledge by spending lots of time on task. Because students' knowledge hierarchy is more fragmented, "knowledge chunks" are smaller than those of experts. The limited capacity of short term memory makes the cognitive load high during problem solving tasks, leaving few cognitive resources available for metacognition. The abstract nature of the laws of physics and the chain of reasoning required to draw meaningful inferences makes these issues critical. In order to help students, it is crucial to consider the difficulty of a problem from the perspective of students. We are developing and evaluating interactive problem-solving tutorials to help students in the introductory physics courses learn effective problem-solving strategies while solidifying physics concepts. The self-paced tutorials can provide guidance and support for a variety of problem solving techniques, and opportunity for knowledge and skill acquisition.

    Miller, A. [Univ. of New Brunswick, Fredericton, New Brunswick (Canada)

    1999-06-01

    Human influences create both environmental problems and barriers to effective policy aimed at addressing those problems. In effect, environmental managers manage people as much as they manage the environment. Therefore, they must gain an understanding of the psychological and sociopolitical dimensions of environmental problems that they are attempting to resolve. The author reappraises conventional analyses of environmental problems using lessons from the psychosocial disciplines. The author combines the disciplines of ecology, political sociology and psychology to produce a more adaptive approach to problem-solving that is specifically geared toward the environmental field. Numerous case studies demonstrate the practical application of theory in a way that is useful to technical and scientific professionals as well as to policymakers and planners.

    In studying General Equilibrium Theory the student must master first the theory and then apply it to solve problems. At the graduate level there is no book devoted exclusively to teaching problem solving. This book teaches for the first time the basic methods of proof and problem solving in General Equilibrium Theory. The problems cover the entire spectrum of difficulty; some are routine, some require a good grasp of the material involved, and some are exceptionally challenging. The book presents complete solutions to two hundred problems. In searching for the basic required techniques, the student will find a wealth of new material incorporated into the solutions. The student is challenged to produce solutions which are different from the ones presented in the book.

    Full Text Available The identification problem of the existing structures though the Quasi-Newton and its modification, Trust region algorithms is discussed. For the structural problems, which could be represented by means of the mathematical modelling of the finite element code discussed method is extremely useful. The nonlinear minimization problem of the L2 norm for the structures with linear elastic behaviour is solved by using of the Optimization Toolbox of Matlab. The direct and inverse procedures for the composition of the desired function to minimize are illustrated for the spatial 3D truss structure as well as for the problem of plane finite elements. The truss identification problem is solved with 2 and 3 unknown parameters in order to compare the computational efforts and for the graphical purposes. The particular commands of the Matlab codes are present in this paper.

  4. The Guderley problem revisited

    Ramsey, Scott D [Los Alamos National Laboratory; Kamm, James R [Los Alamos National Laboratory; Bolstad, John H [NON LANL

    2009-01-01

    The self-similar converging-diverging shock wave problem introduced by Guderley in 1942 has been the source of numerous investigations since its publication. In this paper, we review the simplifications and group invariance properties that lead to a self-similar formulation of this problem from the compressible flow equations for a polytropic gas. The complete solution to the self-similar problem reduces to two coupled nonlinear eigenvalue problems: the eigenvalue of the first is the so-called similarity exponent for the converging flow, and that of the second is a trajectory multiplier for the diverging regime. We provide a clear exposition concerning the reflected shock configuration. Additionally, we introduce a new approximation for the similarity exponent, which we compare with other estimates and numerically computed values. Lastly, we use the Guderley problem as the basis of a quantitative verification analysis of a cell-centered, finite volume, Eulerian compressible flow algorithm.

  5. Histone profiles in cancer.

    Science.gov (United States)

    Riedel, Simone S; Neff, Tobias; Bernt, Kathrin M

    2015-10-01

    While DNA abnormalities have long been recognized as the cause of cancer, the contribution of chromatin is a relatively recent discovery. Excitement in the field of cancer epigenetics is driven by 3 key elements: 1. Chromatin may play an active and often critical role in controlling gene expression, DNA stability and cell identity. 2. Chromatin modifiers are frequent targets of DNA aberrations, in some cancers reaching near 100%. Particularly in cancers with low rates of DNA mutations, the key "driver" of malignancy is often a chromatin modifier. 3. Cancer-associated aberrant chromatin is amenable to pharmacologic modulation. This has sparked the rapidly expanding development of small molecules targeting chromatin modifiers or reader domains, several of which have shown promise in clinical trials. In parallel, technical advances have greatly enhanced our ability to perform comprehensive chromatin/histone profiling. Despite the discovery that distinct histone profiles are associated with prognostic subgroups, and in some instances may point towards an underlying aberration that can be targeted, histone profiling has not entered clinical diagnostics. Even eligibility for clinical trials targeting chromatin hinges on traditional histologic or DNA-based molecular criteria rather than chromatin profiles. This review will give an overview of the philosophical debate around the role of histones in controlling or modulating gene expression and discuss the most common techniques for histone profiling. In addition, we will provide prominent examples of aberrantly expressed or mutated chromatin modifiers that result in either globally or locally aberrant histone profiles, and that may be promising therapeutic targets.

  6. Sparse Representation Denoising for Radar High Resolution Range Profiling

    Directory of Open Access Journals (Sweden)

    Min Li

    2014-01-01

    Full Text Available Radar high resolution range profile has attracted considerable attention in radar automatic target recognition. In practice, radar return is usually contaminated by noise, which results in profile distortion and recognition performance degradation. To deal with this problem, in this paper, a novel denoising method based on sparse representation is proposed to remove the Gaussian white additive noise. The return is sparsely described in the Fourier redundant dictionary and the denoising problem is described as a sparse representation model. Noise level of the return, which is crucial to the denoising performance but often unknown, is estimated by performing subspace method on the sliding subsequence correlation matrix. Sliding window process enables noise level estimation using only one observation sequence, not only guaranteeing estimation efficiency but also avoiding the influence of profile time-shift sensitivity. Experimental results show that the proposed method can effectively improve the signal-to-noise ratio of the return, leading to a high-quality profile.

    The present study utilized a person-centered approach to examine the different profiles of problem sleepers in a community sample of elderly. In addition, this study also explores how demographic and psychiatric variables may be related to these different profiles of sleep problems. A total of 515 participants (Mean age = 67 years, SD = 5) were administered self-report measures of sleep problems, depression and anxiety. Among them, 230 who reported significant problems in any of five selected sleep components were entered into a latent class analysis. The remaining 285 participants were assigned to a comparison control group. The profiles of 'inadequate sleep', 'disturbed sleep', 'trouble falling asleep' and 'multiple problems' were identified. The 'multiple problems' group had significantly higher levels of depression and anxiety relative to the control group. Regression analyses indicated that these different profiles had contributed to a significant increase in variance explained in anxiety but not depression levels, on top of the severity of sleep problems and demographic variables. Although sleep problems occur among the elderly with considerable heterogeneity, they can generally be classified into four different profiles. Furthermore, the inclusion of sleep problem profiles can significantly enhance the prediction of anxiety symptoms. Copyright © 2017 Elsevier B.V. All rights reserved.

    2017-09-23

    Midlife adults are a "pivot" generation, responding to parents' and grown children's problems. Yet, some midlife adults may have families where multiple members suffer sorrows, whereas other midlife adults may have families with few problems. This study examined: (a) typologies of problems across generations and (b) associations between profiles of problems and midlife adults' well-being. Midlife adults (N = 633) reported their own, each parent's (n = 868), and grown child's (n = 1,785) physical (e.g., injury, cancer), psychological (e.g., anxiety, addiction), and lifestyle problems (e.g., divorce, job loss), and parents' functional disabilities. Midlife adults reported their own depressive symptoms. Latent profile analysis revealed four family typologies: (a) lowest problems across generations (n = 364), (b) offspring and midlife adult moderate problems, parent high physical problems and disability (n = 165), (c) offspring and parent moderate problems (n = 90), and (d) offspring highest problems (n = 14). Midlife adults in the lowest problems group (Profile a) reported higher income and fewer depressive symptoms than midlife adults in the other groups. Midlife adults cope with challenges when grown children or parents suffer problems, and their well-being may suffer as a result. In this study, regardless of the profile, higher problems in either generation were associated with more depressive symptoms for midlife adults.

    CERN Document Server

    2012-01-01

    The ultrasonic velocity profile (UVP) method, first developed in medical engineering, is now widely used in clinical settings. The fluid mechanical basis of UVP was established in investigations by the author and his colleagues with work demonstrating that UVP is a powerful new tool in experimental fluid mechanics. There are diverse examples, ranging from problems in fundamental fluid dynamics to applied problems in mechanical, chemical, nuclear, and environmental engineering. In all these problems, the methodological principle in fluid mechanics was converted from point measurements to spatio-temporal measurements along a line. This book is the first monograph on UVP that offers comprehensive information about the method, its principles, its practice, and applied examples, and which serves both current and new users. Current users can confirm that their application configurations are correct, which will help them to improve the configurations so as to make them more efficient and effective. New users will be...

    This monograph is concerned with Galois theoretical embedding problems of so-called Brauer type with a focus on 2-groups and on finding explicit criteria for solvability and explicit constructions of the solutions. The advantage of considering Brauer type embedding problems is their comparatively simple condition for solvability in the form of an obstruction in the Brauer group of the ground field. This book presupposes knowledge of classical Galois theory and the attendant algebra. Before considering questions of reducing the embedding problems and reformulating the solvability criteria, the

    Full Text Available In this current work, I am proposing a general close examination of Problem Based Learning as a student centered educational method in which a problem constitutes  the starting point of the learning process. Such a method provides students with the suitable knowledge for problem solving and presents numerous and significant differences compared to traditional education.In particular, I analyze the theoretic aspects of problem learning by tracing a history and presenting its structure, clarifying the role of the tutor in the various phases of the learning process.

    In basketball there is the problem of hitting a basket at a determined distance and a determined height. The quantities that can be changed during the inclined throw are the initial velocity and the angle of throw. At first we neglect the air resistance. Then we treat the same problem in a medium (liquid, gas) with constant density. We obtain two differential equations. Then we view special cases of the retarding force.

    Zaruba, Natalya; Fraltsova, Tamara; Snegireva, Tatyana

    2017-11-01

    The article is written based on some results of the long-term scientific research of the problem related to the urgent need to find the ways of training personnel for the innovative coal industry in the higher education system. This is due to the fundamental changes in the Russian social and economic conditions: the change in the social system and the owner of the coal industry, the emergence of new technologies in the field of coal mining and processing, and in the management of these processes. At the same time, the system of training specialists for the coal industry in the higher education institutions has largely remained unchanged: technologies and principles of training, scientific approaches and concepts take little account of the changed situation, traditional views of specialists work-ing in the university continue to dominate innovative ideas. Many innovations, especially related to technology and the principles of education, struggle to make their way into the higher education system. The article substantiates the urgency of the problem of training personnel for the innovative coal industry in the higher education system, as well as the importance of scientific analysis of the problem in order to find the ways to solve it.

  8. ICC profiles: are we better off without them?

    Science.gov (United States)

    Beretta, Giordano B.; Dispoto, Gary J.; Hoarau, Eric; Lin, I.-Jong; Zeng, Jun

    2011-01-01

    Before ICC profiles, a device-independent document would encode all color in a device independent CIE space like CIELAB. When the document was to be printed, the press person would measure a target and create a color transformation from the CIE coordinates to device coordinates. For office and consumer color printers, the color transformation for a standard paper would be hardwired in the printer driver or the printer firmware. This procedure had two disadvantages: the color transformations required deep expertise to produce and were hard to manage (the latter making them hard to share), and the image data was transformed twice (from input device to colorimetric and then to output device coordinates) introducing discretization errors twice. The first problem was solved with the ICC profile standard, and the last problem was solved by storing the original device dependent coordinates in the document- together with an input ICC profile-so the color management system could first collapse the two profiles and then perform a single color transformation. Unfortunately, there is a wide variety in the quality of ICC profiles. Even worse, the real nightmare is that quite frequently the incorrect ICC profiles are embedded in documents or the color management systems apply the wrong profiles. For consumer and office printers, the solution is to forgo ICC profiles and reduce everything to the single sRGB color space, so only the printer profile is required. However, the sRGB quality is insufficient for print solution providers. How can a modern print workflow solve the ICC profile nightmare?

  16. Colored Traveling Salesman Problem.

    Li, Jun; Zhou, MengChu; Sun, Qirui; Dai, Xianzhong; Yu, Xiaolong

    2015-11-01

    The multiple traveling salesman problem (MTSP) is an important combinatorial optimization problem. It has been widely and successfully applied to the practical cases in which multiple traveling individuals (salesmen) share the common workspace (city set). However, it cannot represent some application problems where multiple traveling individuals not only have their own exclusive tasks but also share a group of tasks with each other. This work proposes a new MTSP called colored traveling salesman problem (CTSP) for handling such cases. Two types of city groups are defined, i.e., each group of exclusive cities of a single color for a salesman to visit and a group of shared cities of multiple colors allowing all salesmen to visit. Evidences show that CTSP is NP-hard and a multidepot MTSP and multiple single traveling salesman problems are its special cases. We present a genetic algorithm (GA) with dual-chromosome coding for CTSP and analyze the corresponding solution space. Then, GA is improved by incorporating greedy, hill-climbing (HC), and simulated annealing (SA) operations to achieve better performance. By experiments, the limitation of the exact solution method is revealed and the performance of the presented GAs is compared. The results suggest that SAGA can achieve the best quality of solutions and HCGA should be the choice making good tradeoff between the solution quality and computing time.

  17. The Steiner tree problem

    CERN Document Server

    Hwang, FK; Winter, P

    1992-01-01

    The Steiner problem asks for a shortest network which spans a given set of points. Minimum spanning networks have been well-studied when all connections are required to be between the given points. The novelty of the Steiner tree problem is that new auxiliary points can be introduced between the original points so that a spanning network of all the points will be shorter than otherwise possible. These new points are called Steiner points - locating them has proved problematic and research has diverged along many different avenues. This volume is devoted to the assimilation of the rich field of intriguing analyses and the consolidation of the fragments. A section has been given to each of the three major areas of interest which have emerged. The first concerns the Euclidean Steiner Problem, historically the original Steiner tree problem proposed by Jarník and Kössler in 1934. The second deals with the Steiner Problem in Networks, which was propounded independently by Hakimi and Levin and has enjoyed the most...

  18. Continuous profiling of magnetotelluric fields

    Energy Technology Data Exchange (ETDEWEB)

    Verdin, Carlos Torres [Univ. of California, Berkeley, CA (United States)

    1991-05-01

    The magnetotelluric (MT) method of mapping ground electrical conductivity is traditionally based on measurement of the surface impedance at widely spaced stations to infer models of the subsurface through a suitable pseudo 1-D inverse or with linearized least-squares inversion for 2- or 3-D geoelectric media. It is well known that small near-surface inhomogeneities can produce spatial discontinuities in the measured electric fields over a wide frequency range and may consequently bias the impedance on a very local scale. Inadequate station spacing effectively aliases the electric field measurements and results in distortions that cannot be removed in subsequent processing or modelling. In order to fully exploit the benefits of magnetotellurics in complex geological environments, closely spaced measurements must be used routinely. This thesis entertains an analysis of MT data taken along continuous profiles and is a first step that will allow more encompassing 2-D sampling techniques to become viable in the years to come. The developments presented here are to a large extent motivated by the physical insight gained from low-contrast solutions to the forward MT problem. These solutions describe the relationship between a perturbation in the electrical conductivity of the subsurface and the ensuing perturbation of the MT response as the output of a linear system. Albeit strictly accurate in a limited subset of practical exploration problems, the linearized solutions allow one to pursue a model independent study of the response characteristics of MT data. In fact, these solutions yield simple expressions for 1-,2-, and 3-D resistivity models which are here examined in progressive sequence.

    Full Text Available Nenhum estudo de peixes e parasitos foi realizado, até o momento, no Lago do Parque do Ingá que sofre influências antrópicas desde seu represamento, em 1970. Este trabalho analisou alguns aspectos ecológicos dos parasitos metazoários dos peixes deste lago. Dos peixes analisados, (69,5% estavam parasitados por pelo menos uma espécie de parasito. Foram encontrados 1.372 parasitos pertencentes à Nematoda (larvas e Platyhelminthes (Monogenea e Cestoda, sendo estes os mais prevalentes e numerosos. O encontro de larvas de cestóides em Tilapia rendalli e Oreochromis niloticus confirma a importância destas espécies como participantes de níveis tróficos intermediários. A maior abundância de T. rendalli e O. niloticus, no local, pode ser um fator determinante no recrutamento de parasitos. O parasito aproveita-se das espécies de hospedeiros mais abundantes para garantir o desenvolvimento de seu ciclo de vida e também por serem os mais disponíveis à predação pelas aves piscívoras ali presentes, o que torna o local de grande importância para a sustentação do ciclo de vida desses parasitos. A baixa diversidade de endoparasitos coletados pode ser justificada pela presença de metais pesados – Cu e Pb – no sedimento, o que deve estar interferindo no desenvolvimento dos invertebrados, possíveis hospedeiros intermediários.Ingá lake was dammed in 1970 and, since then, no study on fish and parasites had been done, but it has suffered anthropic influences.

    2015-01-01

    The orbital boundary value problem, also known as Lambert problem, is revisited. Building upon Lancaster and Blanchard approach, new relations are revealed and a new variable representing all problem classes, under L-similarity, is used to express the time of flight equation. In the new variable, the time of flight curves have two oblique asymptotes and they mostly appear to be conveniently approximated by piecewise continuous lines. We use and invert such a simple approximation to provide an efficient initial guess to an Householder iterative method that is then able to converge, for the single revolution case, in only two iterations. The resulting algorithm is compared, for single and multiple revolutions, to Gooding's procedure revealing to be numerically as accurate, while having a significantly smaller computational complexity.

    Halitosis is a frequently occurring problem, the cause of which is generally to be found in the mouth. The challenge for oral health care providers is to diagnose it correctly and treat it effectively. Differential diagnosis is of great importance in making a distinction between halitosis which originates in the mouth and which does not originate in the mouth. Oral halitosis can be treated effectively by good oral health care. Plaque accumulation on the tongue is the most common cause of oral halitosis. Tongue cleansing, possibly in combination with a specific mouth wash, is consequently recommended as an element of oral hygiene care. Other oral health problems, such as periodontal disease, caries and ill-fitting removable dentures should be treated adequately to eliminate these problems as potential causes of halitosis.

    In brief Although many problems in young ballet dancers are related to anatomical structure, these panelists point out that good early training is essential. For instance, turning out from the hip instead of the knee would prevent most knee injuries. Ironically, the best training is available to the dancers who need it the least-the professionals. The panelists also discuss back and foot problems, ankle injury, scoliosis, and diet. Dancers often avoid physicians because they ask them to stop dancing.

    The problems of estimation of the minimum average time complexity of decision trees and design of efficient algorithms are complex in general case. The upper bounds described in Chap. 2.4.3 can not be applied directly due to large computational complexity of the parameter M(z). Under reasonable assumptions about the relation of P and NP, there are no polynomial time algorithms with good approximation ratio [12, 32]. One of the possible solutions is to consider particular classes of problems and improve the existing results using characteristics of the considered classes. © Springer-Verlag Berlin Heidelberg 2011.

    Would you like to influence CERN’s safety courses? Do you want to help build better training courses? If your answer is yes to one or both of these questions: now is the time! The Safety Training section is looking for volunteers from the whole CERN community to test new courses before they go online for all members of the personnel.    The Safety Training section is redesigning the CERN e-learning package in order to adopt a more educational approach and to make the courses a more enjoyable experience. The section is now calling for volunteers. “We know we can do much more with testers’ help and feedback,” explains Christoph Balle, Safety Training section leader. “By having the end users actively involved in the process, we’ll achieve our goal of communicating safety in the best possible way. As the volunteers will play an active role in the development of the courses, they will be providing a service to the whole community.&am...

    2010-12-01

    Full Text Available The goal of this tutorial is to describe and synthesize the concepts and techniques used in the design of recommendation systems that can deal with user profiles. The development of such recommendation systems requires solutions of two sub problems: (i the creation and maintenance of user profile, and; (ii the appropriate use of user profiles. This work is a theoretical tutorial on this subject. This is a useful text for people who are interested in the theoretical foundations of modeling user profile and recommendation systems. This text presents illustrative diagrams that summarize the main components used in the modeling of user profiles

  16. Transcriptional Profiling of Chromera velia Under Diverse Environmental Conditions

    KAUST Repository

    Tayyrov, Annageldi

    2014-05-01

    Since its description in 2008, Chromera velia has drawn profound interest as the closest free-­‐living photosynthetic relative of apicomplexan parasites that are significant pathogens, causing enormous health and economic problems. There-­‐ fore, this newly described species holds a great potential to understand evolu-­‐ tionary basis of how photosynthetic algae evolved into the fully pathogenic Apicomplexa and how their common ancestors may have lived before they evolved into obligate parasites. Hence, the aim of this work is to understand how C. velia function and respond to different environmental conditions. This study aims to reveal how C. velia is able to respond to environmental perturbations that are applied individually and simultaneously since, studying stress factors in separation fails to elucidate complex responses to multi stress factors and un-­‐ derstanding the systemic regulation of involved genes. To extract biologically significant information and to identify genes involved in various physiological processes under variety of environmental conditions (i.e. a combination of vary-­‐ ing temperatures, iron availability, and salinity in the growth medium) we pre-­‐ pared strand specific RNA-­‐seq libraries for 83 samples in diverse environmental conditions. Here, we report the set of significantly differentially expressed genes as a re-­‐ sponse to the each condition and their combinations. Several interesting up-­‐ regulated and down-­‐regulated genes were found and their functions and in-­‐ volved pathways were studied. We showed that the profound regulation of HSP20 proteins is significant under stress conditions and hypothesized that the-­‐ se proteins might be involved in their movements.
