    Full Text Available Abstract Free-living flatworms ("Turbellaria" are appropriate model organisms to gain better insight into the role of stem cells in ageing and rejuvenation. Ageing research in flatworms is, however, still scarce. This is partly due to culture difficulties and the lack of a complete set of demographic data, including parameters such as median lifespan and age-specific mortality rate. In this paper, we report on the first flatworm survival analysis. We used the species Macrostomum lignano, which is an emerging model for studying the reciprocal influence between stem cells, ageing and rejuvenation. This species has a median lifespan of 205 ± 13 days (average ± standard deviation [SD] and a 90th percentile lifespan of 373 ± 32 days. The maximum lifespan, however, is more than 745 days, and the average survival curve is characterised by a long tail because a small number of individuals lives twice as long as 90% of the population. Similar to earlier observations in a wide range of animals, in M. lignano the age-specific mortality rate increases exponentially, but levels off at the oldest ages. To compare the senescence of M. lignano with that of other ageing models, we determined the mortality rate doubling time, which is 0.20 ± 0.02 years. As a result, we can conclude that M. lignano shows gradual senescence at a rate similar to the vertebrate ageing models Rattus norvegicus and Mus musculus. We argue that M. lignano is a suitable model for ageing and rejuvenation research, and especially for the role of stem cells in these processes, due to its accessible stem cell system and regeneration capacity, and the possibility of combining stem cell studies with demographic analyses.

    The regeneration-capable flatworm Macrostomum lignano is a powerful model organism to study the biology of stem cells in vivo. As a flatworm amenable to transgenesis, it complements the historically used planarian flatworm models, such as Schmidtea mediterranea. However, information on the transcriptome and markers of stem cells in M. lignano is limited. We generated a de novo transcriptome assembly and performed the first comprehensive characterization of gene expression in the proliferating cells of M. lignano, represented by somatic stem cells, called neoblasts, and germline cells. Knockdown of a selected set of neoblast genes, including Mlig-ddx39, Mlig-rrm1, Mlig-rpa3, Mlig-cdk1, and Mlig-h2a, confirmed their crucial role for the functionality of somatic neoblasts during homeostasis and regeneration. The generated M. lignano transcriptome assembly and gene expression signatures of somatic neoblasts and germline cells will be a valuable resource for future molecular studies in M. lignano.

    Over the past decade, the free-living flatworm Macrostomum lignano has been successfully used in many areas of biology, including embryology, stem cells, sexual selection, bioadhesion and aging. The increased use of this powerful laboratory model, including the establishment of genomic resources and tools, makes it essential to have a detailed description of the chromosome organization of this species, previously suggested to have a karyotype with 2n = 8 and one pair of large and three pairs of small metacentric chromosomes. We performed cytogenetic analyses for chromosomes of one commonly used inbred line of M. lignano (called DV1) and uncovered unexpected chromosome number variation in the form of aneuploidies of the largest chromosomes. These results prompted us to perform karyotypic studies in individual specimens of this and other lines of M. lignano reared under laboratory conditions, as well as in freshly field-collected specimens from different natural populations. Our analyses revealed a high frequency of aneuploids and in some cases other numerical and structural chromosome abnormalities in laboratory-reared lines of M. lignano, and some cases of aneuploidy were also found in freshly field-collected specimens. Moreover, karyological analyses were performed in specimens of three further species: Macrostomum sp. 8 (a close relative of M. lignano), M. spirale and M. hystrix. Macrostomum sp. 8 showed a karyotype that was similar to that of M. lignano, with tetrasomy for its largest chromosome being the most common karyotype, while the other two species showed a simpler karyotype that is more typical of the genus Macrostomum. These findings suggest that M. lignano and Macrostomum sp. 8 can be used as new models for studying processes of partial genome duplication in genome evolution. PMID:27755577

    Neoblasts are potentially totipotent stem cells and the only proliferating cells in adult Platyhelminthes. We have examined the cellular dynamics of neoblasts during the posterior regeneration of Macrostomum lignano. Double-labeling of neoblasts with bromodeoxyuridine and the anti-phospho histone H3 mitosis marker has revealed a complex cellular response in the first 48 h after amputation; this response is different from that known to occur during regeneration in triclad platyhelminths and in starvation/feeding experiments in M. lignano. Mitotic activity is reduced during the first 8 h of regeneration but, at 48 h after amputation, reaches almost twice the value of control animals. The total number of S-phase cells significantly increases after 1 day of regeneration. A subpopulation of fast-cycling neoblasts surprisingly shows the same dynamics during regeneration as those in control animals. Wound healing and regeneration are accompanied by the formation of a distinct blastema. These results present new insights, at the cellular level, into the early regeneration of rhabditophoran Platyhelminthes.

  6. Stem cells propagate their DNA by random segregation in the flatworm Macrostomum lignano.

    Full Text Available Adult stem cells are proposed to have acquired special features to prevent an accumulation of DNA-replication errors. Two such mechanisms, frequently suggested to serve this goal are cellular quiescence, and non-random segregation of DNA strands during stem cell division, a theory designated as the immortal strand hypothesis. To date, it has been difficult to test the in vivo relevance of both mechanisms in stem cell systems. It has been shown that in the flatworm Macrostomum lignano pluripotent stem cells (neoblasts are present in adult animals. We sought to address by which means M. lignano neoblasts protect themselves against the accumulation of genomic errors, by studying the exact mode of DNA-segregation during their division. In this study, we demonstrated four lines of in vivo evidence in favor of cellular quiescence. Firstly, performing BrdU pulse-chase experiments, we localized 'Label-Retaining Cells' (LRCs. Secondly, EDU pulse-chase combined with Vasa labeling demonstrated the presence of neoblasts among the LRCs, while the majority of LRCs were differentiated cells. We showed that stem cells lose their label at a slow rate, indicating cellular quiescence. Thirdly, CldU/IdU- double labeling studies confirmed that label-retaining stem cells showed low proliferative activity. Finally, the use of the actin inhibitor, cytochalasin D, unequivocally demonstrated random segregation of DNA-strands in LRCs. Altogether, our data unambiguously demonstrated that the majority of neoblasts in M. lignano distribute their DNA randomly during cell division, and that label-retention is a direct result of cellular quiescence, rather than a sign of co-segregation of labeled strands.

    PIWI proteins and piRNA pathways are essential for transposon silencing and some aspects of gene regulation during animal germline development. In contrast to most animal species, some flatworms also express PIWIs and piRNAs in somatic stem cells, where they are required for tissue renewal and regeneration. Here, we have identified and characterized piRNAs and PIWI proteins in the emerging model flatworm Macrostomum lignano. We found that M. lignano encodes at least three PIWI proteins. One of these, Macpiwi1, acts as a key component of the canonical piRNA pathway in the germline and in somatic stem cells. Knockdown of Macpiwi1 dramatically reduces piRNA levels, derepresses transposons, and severely impacts stem cell maintenance. Knockdown of the piRNA biogenesis factor Macvasa caused an even greater reduction in piRNA levels with a corresponding increase in transposons. Yet, in Macvasa knockdown animals, we detected no major impact on stem cell self-renewal. These results may suggest stem cell maintenance functions of PIWI proteins in flatworms that are distinguishable from their impact on transposons and that might function independently of what are considered canonical piRNA populations.

    Full Text Available Abstract Background Macrostomum lignano is a small free-living flatworm capable of regenerating all body parts posterior of the pharynx and anterior to the brain. We quantified the cellular composition of the caudal-most body region, the tail plate, and investigated regeneration of the tail plate in vivo and in semithin sections labeled with bromodeoxyuridine, a marker for stem cells (neoblasts in S-phase. Results The tail plate accomodates the male genital apparatus and consists of about 3,100 cells, about half of which are epidermal cells. A distinct regeneration blastema, characterized by a local accumulation of rapidly proliferating neoblasts and consisting of about 420 cells (excluding epidermal cells, was formed 24 hours after amputation. Differentiated cells in the blastema were observed two days after amputation (with about 920 blastema cells, while the male genital apparatus required four to five days for full differentiation. At all time points, mitoses were found within the blastema. At the place of organ differentiation, neoblasts did not replicate or divide. After three days, the blastema was made of about 1420 cells and gradually transformed into organ primordia, while the proliferation rate decreased. The cell number of the tail plate, including about 960 epidermal cells, was restored to 75% at this time point. Conclusion Regeneration after artificial amputation of the tail plate of adult specimens of Macrostomum lignano involves wound healing and the formation of a regeneration blastema. Neoblasts undergo extensive proliferation within the blastema. Proliferation patterns of S-phase neoblasts indicate that neoblasts are either determined to follow a specific cell fate not before, but after going through S-phase, or that they can be redetermined after S-phase. In pulse-chase experiments, dispersed distribution of label suggests that S-phase labeled progenitor cells of the male genital apparatus undergo further proliferation before

    Full Text Available Abstract Background Flatworms are characterized by an outstanding stem cell system. These stem cells (neoblasts can give rise to all cell types including germ cells and power the exceptional regenerative capacity of many flatworm species. Macrostomum lignano is an emerging model system to study stem cell biology of flatworms. It is complementary to the well-studied planarians because of its small size, transparency, simple culture maintenance, the basal taxonomic position and its less derived embryogenesis that is more closely related to spiralians. The development of cell-, tissue- and organ specific markers is necessary to further characterize the differentiation potential of flatworm stem cells. Large scale in situ hybridization is a suitable tool to identify possible markers. Distinguished genes identified in a large scale screen in combination with manipulation of neoblasts by hydroxyurea or irradiation will advance our understanding of differentiation and regulation of the flatworm stem cell system. Results We have set up a protocol for high throughput large scale whole mount in situ hybridization for the flatworm Macrostomum lignano. In the pilot screen, a number of cell-, tissue- or organ specific expression patterns were identified. We have selected two stem cell- and germ cell related genes – macvasa and macpiwi – and studied effects of hydroxyurea (HU treatment or irradiation on gene expression. In addition, we have followed cell proliferation using a mitosis marker and bromodeoxyuridine labeling of S-phase cells after various periods of HU exposure or different irradiation levels. HU mediated depletion of cell proliferation and HU induced reduction of gene expression was used to generate a cDNA library by suppressive subtractive hybridization. 147 differentially expressed genes were sequenced and assigned to different categories. Conclusion We show that Macrostomum lignano is a suitable organism to perform high throughput large

    Full Text Available Based on the chemical structure and the known chemical synthesis of the marine sponge alkaloid ageladine A, we synthesized the ageladine A-derivative 4-(naphthalene-2-yl-1H-imidazo[4,5-c]pyridine trifluoroacetate (LysoGlow84. The two-step synthesis started with the Pictet-Spengler reaction of histamine and naphthalene-2-carbaldehyde to a tetrahydropyridine intermediate, which was dehydrogenated with activated manganese (IV oxide to LysoGlow84. Structure and purity of the synthesized LysoGlow84 were confirmed by NMR spectroscopy and mass spectrometry. The fluorescence intensity emitted by LysoGlow84 depended strongly on the pH of the solvent with highest fluorescence intensity recorded at pH 4. The fluorescence maximum (at 315 nm excitation was observed at 440 nm. Biocompatibility of LysoGlow84 was investigated using cultured rat brain astrocytes and the marine flatworm Macrostomum lignano. Exposure of the astrocytes for up to 6 h to micromolar concentrations of LysoGlow84 did not compromise cell viability, as demonstrated by several viability assays, but revealed a promising property of this compound for staining of cellular vesicles. Conventional fluorescence microscopy as well as confocal scanning microscopy of LysoGlow84-treated astrocytes revealed co-localization of LysoGlow84 fluorescence with that of LysoTracker® Red DND-99. LysoGlow84 stained unclear structures in Macrostomum lignano, which were identified as lysosomes by co-staining with LysoTracker. Strong fluorescence staining by LysoGlow84 was further observed around the worms’ anterior gut and the female genital pore which were not counterstained by LysoTracker Red. Thus, LysoGlow84 is a new promising dye that stains lysosomes and other acidic compartments in cultured cells and in worms.

    Neoblasts in Platyhelminthes are the only cells to proliferate and differentiate into all cell types. In Macrostomum lignano, the incorporation of 5'-bromo-2'-deoxyuridine (BrdU) in neoblasts confirmed the distribution of S-phase cells in two lateral bands. BrdU labeling for light and for transmission electron microscopy (TEM) identified three populations of proliferating cells: somatic neoblasts located between the epidermis and gastrodermis (mesodermal neoblasts), neoblasts located within the gastrodermis (gastrodermal neoblasts), and gonadal S-phase cells. In adults, three stages of mesodermal neoblasts (2, 2-3, and 3) defined by their ultrastructure were found. Stage 1 neoblasts where only seen in hatchlings. These stages either were phases within the S-phase of one neoblast pool or were subsequent stages of differentiating neoblasts, each with its own cell cycle. Regular TEM and immunogold labeling provided the basis for calculating the total number of neoblasts and the ratio of labeled to non-labeled neoblasts. Somatic neoblasts represented 6.5% of the total number of cells. Of these, 27% were labeled in S-phase. Of this fraction, 33% were in stage 2, 46% in stage 2-3, and 21% in stage 3. Immunogold labeling substantiated results concerning the differentiation of neoblasts into somatic cells. Non-labeled stage 2 neoblasts were present, even after a 2-week BrdU exposure. Double labeling of mitoses and FMRF-amide revealed a close spatial relationship of mesodermal neoblasts with the nervous system. Immunogold-labeled sections showed that nearly 70% of S-phase cells were in direct contact or within 5 microm from nerve cords.

    Full Text Available The marine plathyhelminth Macrostomum lignano was recently isolated from Adriatic shore sediments where it experiences a wide variety of environmental challenges, ranging from hypoxia and reoxygenation, feeding on toxic algae, to exposure to anthropogenic contaminants. As multidrug resistance transporters constitute the first line of defense against toxins and toxicants we have studied the presence of such transporters in M. lignano in living animals by applying optical methods and pharmacological inhibitors that had been developed for mammalian cells. Application of the MDR1 inhibitor Verapamil or of the MRP1 inhibitors MK571 or Probenecid increased the intracellular fluorescence of the reporter dyes Fura-2 am, Calcein am, Fluo-3 am in the worms, but did not affect their staining with the dyes Rhodamine B, CMFDA or Ageladine A. The marine sponge alkaloid Ageladine A remained intracellularly trapped for several days in the worms, suggesting that it does not serve as substrate of multidrug resistance exporters. In addition, Ageladine A did not affect multidrug resistance-associated protein (MRP-mediated dye export from M. lignano or the MRP1-mediated glutathione (GSH export from cultured rat brain astrocytes. The data obtained demonstrate that life-imaging is a useful tool to address physiological drug export from intact marine transparent flatworms by using multiphoton scanning microscopy.

    Previous studies demonstrated complex architecture of the muscular system of Macrostomum species, especially in the rostrum area and the pharynx. However, little is known about the differences in muscular pattern between species of the genus. This study examines and compares the muscular systems of specimens belonging to three freshwater Macrostomum species (M. quiritium, M. tuba and M. velastylum), labeled with phalloidin-rhodamine and studied by confocal microscopy. Our results agree with the previous descriptions, confirming that the muscular patterns for the body wall, rostrum area, pharynx and caudal region differ among species. The muscles of the body wall follow the typical architecture, but the number of fibers in the species analyzed varies between dorsal and ventral surfaces, ranging from 80 to 100 fibers, this record being higher than previous observations. The arrangement of the fibers in the rostrum is complex, especially in the brain area. Macrostomum tuba and M. quiritium have a set of two muscles crossing at brain level and forming an "X," which is not evident in M. velastylum. We identified five different sets of fibers associated to the pharynx and mouth at ventral, medium and deep levels. These different sets are present in all three species studied. The caudal plate in M. tuba has an additional layer of diagonal fibers in the body wall, which is not evident in the other two species. The muscles of the reproductive system are independent of the body wall musculature in the species analyzed, but connected to the intestinal wall by specific fibers that may serve as an anchor. J.

    Macrostomum is a diverse genus of turbellarians with more than 180 species described from around the world. However, the Macrostomum fauna in China is poorly known. In this study, three new species of freshwater Macrostomum were described from southern China based on morphology of the penis stylet, an important character for species identification in this genus. In M. heyuanensis n. sp., the penis stylet bends 108° leftwards at its 1/2 length then backwards besides the distal opening, and the terminal region is thicker than other parts of penis stylet. In M. dongyuanensis n. sp., the penis stylet is J-shaped, with the opening at the tail end. In M. bicaudatum n. sp., the penis stylet is C-shaped, with the upper margin of the distal end longer but slimmer than the lower margin. In addition, molecular phylogenetic analyses were conducted to aid the classification of the novel species. Finally, their habitat and taxonomic status are compared and discussed.

    Two new species of brackish-water Macrostomum (M. zhujiangensis n. sp. and M. baoanensis n. sp.) were described based on samples collected from the littoral zone of the Zhujiang Estuary. These are the first records of brackish-water Macrostomum from southern China. Macrostomum zhujiangensis n. sp. and M. baoanensis n. sp. differ from other similar species in the length and morphology of the penis stylet.  The penis stylet of M. zhujiangensis n. sp. is C-shaped and its distal opening has a beveled edge. The penis stylet of M. baoanensis n. sp. is J-shaped and the distal region is thicker than other parts of the penis stylet. Molecular phylogenetic analysis supports the establishment of the new species.

  11. Control of predacious flatworms Macrostomum sp. in culturing juvenile freshwater mussels

    2003-01-01

    Flatworms of the genus Macrostomum are voracious predators on newly metamorphosed juvenile freshwater mussels (Unionidae), which require a fish host to transform mussel larvae into free-living juveniles. Toxicity tests were performed with formalin (paracide-F, 37% formaldehyde) to determine the appropriate levels of treatment for eradicating these flatworms from host fish tanks without adversely affecting the culture of juvenile mussels. Results indicate that a 1-h shock treatment of 250 mg/L formalin or a 3-d continuous exposure to 20 mg/L of formalin kills adult Macrostomum but not fish. Observations indicate that a single treatment is insufficient to kill Macrostomum eggs, so a second treatment after 3 d is necessary to kill newly hatched flatworms. Newly metamorphosed freshwater mussels exposed to similar shock and continuous treatments of formalin were also killed. Thus, all host fish introduced for the purpose of mussel production should be quarantined and treated prophylactically to avoid the infestation of mussel culture systems with predacious flatworms.

    Pygidiopsis macrostomum and Ascocotyle (Phagicola) pindoramensis (Digenea: Heterophyidae) parasitize guppies as intermediate hosts and, respectively, fish-eating mammals or birds as definitive hosts. Heterophyids have zoonotic potential, and molecular studies associated with morphological and ecological aspects have helped to clarify their taxonomy and phylogeny. Poecilia vivipara naturally parasitized by metacercariae of both species (100% prevalence) exhibit no external signs of parasitism. In this work, four new sequences of P. macrostomum (18S rDNA, 28S rDNA and ITS2 rDNA) and one new sequence of A. (P.) pindoramensis (mtDNA cox-1) are presented. Phylogeny reconstructions linked P. macrostomum to other heterophyids, but the separation of the Heterophyidae and Opisthorchiidae remains unclear. Additionally, we used indirect immunocytochemistry and the phalloidin-fluorescence techniques allied with confocal laser scanning microscopy to describe muscular and neuronal structures of P. macrostomum. A complex arrangement of muscular fibres is associated with the tegument, suckers, gut and reproductive system. Radial fibres around the ventral sucker are thick, branched and extend to the body wall. High-resolution confocal imaging revealed a typical digenean muscular arrangement and important heterophyid morphological traits. These data will support future control measures to reduce the parasitism in guppies reared in fish farming systems, especially for aquarium and experimental purposes.

    In this paper, two new brackish-water species of Macrostomum (M. shenzhenensis n. sp. and M qiaochengensis n. sp.) collected from the artificial lake in Overseas Chinese Town mangrove wetland, are described based on the morphology of the penis stylet and on a molecular phylogenetic analysis. M. shenzhenensis n. sp. has an elongate, narrow stylet with torus-shaped distal wall thickening, while M. qiaochengensis n. sp. has a hook-like stylet with a pointed end. Both the 18S and 28S rDNA phylogenetic analyses of M shenzhenensis n. sp. and M qiaochengensis n. sp. support the establishments of these two new species. Finally, categorization of these two new species based on the morphology of sperm and penis stylet, as well as other morphological features of the reproductive system is briefly discussed.

    With this editorial note we would like to update you on the performance of the International Journal of Applied Earth Observation and Geoinformation (JAG) and inform you about changes that have been made to the composition of the editorial team. Our Journal publishes original papers that apply earth observation data for the management of natural resources and the environment. Environmental issues include biodiversity, land degradation, industrial pollution and natural hazards such as earthquakes, floods and landslides. As such the scope is broad and ranges from conceptual and more fundamental work on earth observation and geospatial sciences to the more problem-solving type of work. When I took over the role of Editor-in-Chief in 2012, I together with the Publisher set myself the mission to position JAG in the top-3 of the remote sensing and GIS journals. To do so we strived at attracting high quality and high impact papers to the journal and to reduce the review turnover time to make JAG a more attractive medium for publications. What has been achieved? Have we reached our ambitions? We can say that: The submissions have increased over the years with over 23% for the last 12 months. Naturally not all may lead to more papers, but at least a portion of the additional submissions should lead to a growth in journal content and quality.

    Bhatia, Rajendra

    2009-01-01

    These notes are a record of a one semester course on Functional Analysis given by the author to second year Master of Statistics students at the Indian Statistical Institute, New Delhi. Students taking this course have a strong background in real analysis, linear algebra, measure theory and probability, and the course proceeds rapidly from the definition of a normed linear space to the spectral theorem for bounded selfadjoint operators in a Hilbert space. The book is organised as twenty six lectures, each corresponding to a ninety minute class session. This may be helpful to teachers planning a course on this topic. Well prepared students can read it on their own.

    This note argues, contrary to claims in this journal, that the possible existence of indefinitely many causal factors does not invalidate randomization. The effect of such factors has to be bounded by outcome, and since inference is based on a ratio of between-treatment-group to within-treatment-group variation, randomization remains valid.

  11. Lecture Notes on Multigrid Methods

    Energy Technology Data Exchange (ETDEWEB)

    Vassilevski, P S

    2010-06-28

    The Lecture Notes are primarily based on a sequence of lectures given by the author while been a Fulbright scholar at 'St. Kliment Ohridski' University of Sofia, Sofia, Bulgaria during the winter semester of 2009-2010 academic year. The notes are somewhat expanded version of the actual one semester class he taught there. The material covered is slightly modified and adapted version of similar topics covered in the author's monograph 'Multilevel Block-Factorization Preconditioners' published in 2008 by Springer. The author tried to keep the notes as self-contained as possible. That is why the lecture notes begin with some basic introductory matrix-vector linear algebra, numerical PDEs (finite element) facts emphasizing the relations between functions in finite dimensional spaces and their coefficient vectors and respective norms. Then, some additional facts on the implementation of finite elements based on relation tables using the popular compressed sparse row (CSR) format are given. Also, typical condition number estimates of stiffness and mass matrices, the global matrix assembly from local element matrices are given as well. Finally, some basic introductory facts about stationary iterative methods, such as Gauss-Seidel and its symmetrized version are presented. The introductory material ends up with the smoothing property of the classical iterative methods and the main definition of two-grid iterative methods. From here on, the second part of the notes begins which deals with the various aspects of the principal TG and the numerous versions of the MG cycles. At the end, in part III, we briefly introduce algebraic versions of MG referred to as AMG, focusing on classes of AMG specialized for finite element matrices.

    A number of authors have used the portfolio standard deviation to model the risk reduction advantages of naive diversification. Other authors have pointed out that when risk is modelled by the portfolio's variance the modelling process becomes much simpler and is computationally more efficient. In this note we derive an exact parametric relationship between portfolio standard deviation and size and thus highlight the dangers of using the standard deviation in conjunction with O.L.S. regressio...

  15. Kindergarten Quantum Mechanics lectures notes

    Coecke, B

    2005-01-01

    These lecture notes survey some joint work with Samson Abramsky as it was presented by me at several conferences in the summer of 2005. It concerns `doing quantum mechanics using only pictures of lines, squares, triangles and diamonds'. This picture calculus can be seen as a very substantial extension of Dirac's notation, and has a purely algebraic counterpart in terms of so-called Strongly Compact Closed Categories (introduced by Abramsky and I in quant-ph/0402130 and [4]) which subsumes my Logic of Entanglement quant-ph/0402014. For a survey on the `what', the `why' and the `hows' I refer to a previous set of lecture notes quant-ph/0506132. In a last section we provide some pointers to the body of technical literature on the subject.

  1. Stem cells are differentially regulated during development, regeneration and homeostasis in flatworms.

    De Mulder, Katrien; Pfister, Daniela; Kuales, Georg; Egger, Bernhard; Salvenmoser, Willi; Willems, Maxime; Steger, Jessica; Fauster, Katja; Micura, Ronald; Borgonie, Gaetan; Ladurner, Peter

    2009-10-01

    The flatworm stem cell system is exceptional within the animal kingdom, as totipotent stem cells (neoblasts) are the only dividing cells within the organism. In contrast to most organisms, piwi-like gene expression in flatworms is extended from germ cells to somatic stem cells. We describe the isolation and characterization of the piwi homologue macpiwi in the flatworm Macrostomum lignano. We use in situ hybridization, antibody staining and RNA interference to study macpiwi expression and function in adults, during postembryonic development, regeneration and upon starvation. We found novelties regarding piwi function and observed differences to current piwi functions in flatworms. First, macpiwi was essential for the maintenance of somatic stem cells in adult animals. A knock-down of macpiwi led to a complete elimination of stem cells and death of the animals. Second, the regulation of stem cells was different in adults and regenerates compared to postembryonic development. Third, sexual reproduction of M. lignano allowed to follow germline formation during postembryonic development, regeneration, and starvation. Fourth, piwi expression in hatchlings further supports an embryonic formation of the germline in M. lignano. Our findings address new questions in flatworm stem cell research and provide a basis for comparison with higher organisms.

    Fullwood, R.

    1992-03-01

    These lecture notes for criticality safety are prepared for the training of Department of Energy supervisory, project management, and administrative staff. Technical training and basic mathematics are assumed. The notes are designed for a two-day course, taught by two lecturers. Video tapes may be used at the options of the instructors. The notes provide all the materials that are necessary but outside reading will assist in the fullest understanding. The course begins with a nuclear physics overview. The reader is led from the macroscopic world into the microscopic world of atoms and the elementary particles that constitute atoms. The particles, their masses and sizes and properties associated with radioactive decay and fission are introduced along with Einstein's mass-energy equivalence. Radioactive decay, nuclear reactions, radiation penetration, shielding and health-effects are discussed to understand protection in case of a criticality accident. Fission, the fission products, particles and energy released are presented to appreciate the dangers of criticality. Nuclear cross sections are introduced to understand the effectiveness of slow neutrons to produce fission. Chain reactors are presented as an economy; effective use of the neutrons from fission leads to more fission resulting in a power reactor or a criticality excursion. The six-factor formula is presented for managing the neutron budget. This leads to concepts of material and geometric buckling which are used in simple calculations to assure safety from criticality. Experimental measurements and computer code calculations of criticality are discussed. To emphasize the reality, historical criticality accidents are presented in a table with major ones discussed to provide lessons-learned. Finally, standards, NRC guides and regulations, and DOE orders relating to criticality protection are presented.

    CERN Document Server

    Zannier, Umberto

    2014-01-01

    These lecture notes originate from a course delivered at the Scuola Normale in Pisa in 2006. Generally speaking, the prerequisites do not go beyond basic mathematical material and are accessible to many undergraduates. The contents mainly concern diophantine problems on affine curves, in practice describing the integer solutions of equations in two variables. This case historically suggested some major ideas for more general problems. Starting with linear and quadratic equations, the important connections with Diophantine Approximation are presented and Thue's celebrated results are proved in full detail. In later chapters more modern issues on heights of algebraic points are dealt with, and applied to a sharp quantitative treatment of the unit equation. The book also contains several Supplements, hinted exercises and an Appendix on recent work on heights.

  9. A note on neglect defaulting

    Directory of Open Access Journals (Sweden)

    Howard Margolis

    2008-04-01

    Full Text Available I introduce the notion of ``neglect defaulting,'' which labels the propensity to neglect possibilities which are ordinarily sensibly neglected. In familiar contexts we are well-tuned to recognize when to override the default. But outside the range of familiar experience --- here in the artificial context of puzzles --- these ordinarily benign defaults can make it difficult for even sophisticated subjects, such as readers of this note, to avoid responses which on reflection will be seen as obviously mistaken. A detail of particular importance is that, although subjects are easily prompted to take one step in the direction of reaching a sound response, the tendency to then neglect to consider that another step may be needed is remarkably strong. In each of the five examples the needed but usually neglected second step is quite trivial. Concluding remarks point to consequences for larger questions outside the range of familiar experience, in politics and other contexts out of scale with everyday experience.

  10. Lecture notes on wavelet transforms

    CERN Document Server

    Debnath, Lokenath

    2017-01-01

    This book provides a systematic exposition of the basic ideas and results of wavelet analysis suitable for mathematicians, scientists, and engineers alike. The primary goal of this text is to show how different types of wavelets can be constructed, illustrate why they are such powerful tools in mathematical analysis, and demonstrate their use in applications. It also develops the required analytical knowledge and skills on the part of the reader, rather than focus on the importance of more abstract formulation with full mathematical rigor.  These notes differs from many textbooks with similar titles in that a major emphasis is placed on the thorough development of the underlying theory before introducing applications and modern topics such as fractional Fourier transforms, windowed canonical transforms, fractional wavelet transforms, fast wavelet transforms, spline wavelets, Daubechies wavelets, harmonic wavelets and non-uniform wavelets. The selection, arrangement, and presentation of the material in these ...

  11. Lecture notes: Astrophysical fluid dynamics

    CERN Document Server

    Ogilvie, Gordon I

    2016-01-01

    These lecture notes and example problems are based on a course given at the University of Cambridge in Part III of the Mathematical Tripos. Fluid dynamics is involved in a very wide range of astrophysical phenomena, such as the formation and internal dynamics of stars and giant planets, the workings of jets and accretion discs around stars and black holes, and the dynamics of the expanding Universe. Effects that can be important in astrophysical fluids include compressibility, self-gravitation and the dynamical influence of the magnetic field that is 'frozen in' to a highly conducting plasma. The basic models introduced and applied in this course are Newtonian gas dynamics and magnetohydrodynamics (MHD) for an ideal compressible fluid. The mathematical structure of the governing equations and the associated conservation laws are explored in some detail because of their importance for both analytical and numerical methods of solution, as well as for physical interpretation. Linear and nonlinear waves, includin...

  12. A note on thermal activation

    Boyanovsky, D; Lee, D S; Silva, J P; Daniel Boyanovsky; Richard Holman; Da-Shin Lee; Joao P Silva

    Thermal activation is mediated by field configurations that correspond to saddle points of the energy functional. The rate of probability flow along the unstable functional directions, i.e the activation rate, is usually obtained from the imaginary part of a suitable analytic continuation of the equilibrium free energy. In this note we provide a real-time, non-equilibrium interpretation of this imaginary part which is analogous to the real-time interpretation of the imaginary part of the one-loop effective potential in theories with symmetry breaking. We argue that in situations in which the system is strongly out of equilibrium the rate will be time dependent and illustrate this with an example.

  13. Notes on Anomaly Induced Transport

    CERN Document Server

    Landsteiner, Karl

    2016-01-01

    Chiral anomalies give rise to dissipationless transport phenomena such as the chiral magnetic and vortical effects. In these notes I review the theory from a quantum field theoretic, hydrodynamic and holographic perspective. A physical interpretation of the otherwise somewhat obscure concepts of consistent and covariant anomalies will be given. Vanishing of the CME in strict equilibrium will be connected to the boundary conditions in momentum space imposed by the regularization. The role of the gravitational anomaly will be explained. That it contributes to transport in an unexpectedly low order in the derivative expansion can be easiest understood via holography. Anomalous transport is supposed to play also a key role in understanding the electronics of advanced materials, the Dirac- and Weyl (semi)metals. Anomaly related phenomena such as negative magnetoresistivity, anomalous Hall effect, thermal anomalous Hall effect and Fermi arcs can be understood via anomalous transport. Finally I briefly review a holo...

  14. Data Glove For Note Taking

    Directory of Open Access Journals (Sweden)

    2012-11-01

    Full Text Available We aim at creating a note-taking device typically to be used in a classroom environment. Traditional methods of writing have limited speed and cannot keep up with speech. Writing with pen on paper requires us to look at the paper, which can reduce concentration on the ongoing discussion. Laptops are costly, power consuming and heavy for such a trivial task. Voice to text programs dont have the freedom of choosing the text to be included, and noise in the room can affect performance of such a program. Smart phones have a small keypad, which demands more user concentration. We have created a glove that one can wear and touch-type on any flat surface with minimal costs and power consumption. With ergonomics in mind, the glove has been designed to yield ten self fabricated switch button sensors to finally create a complete utility for simple and an inexpensive typing tool.

    Full Text Available In their seminal article, Sacks, Schegloff and Jefferson (1974 examine procedures for turn-taking in conversation. Sometimes, they note, a s peaker will select who has the next turn, but more frequently a "self-select" system operates, whereby the participants in a conversation themselves determine when they wish to speak. But how, ask Sacks, Schegloff and Jefferson, do the interlocutors secure a turn in the ongoing flow of another speaker's utterance? To answer this question the authors introduce the notion of "transition relevance place", that is, a point in the turn-holder's utterance where another speaker is most likely to take up a turn. Clearly the most obvious transition relevance place occurs at the end of an utterance sentence, where a pause may be made. However, clause or thersyntactic boundaries also offer opportunities for other speakers to interrupt. As Sacks et al point out, if conversational participants do not take up a turn at a transition relevance place the turn holder will normally continue.

    2012-06-01

    Full Text Available On the basis of ever-mounting evidence, amongst which is the “zone” problematic of the Zadar conference that occassioned these notes, it can be concluded that the spatial turn has insinuated itself as an all-pervading heuristic tool throughout the humanities and the social sciences. The extent to which space and spatiality have usurped the central stage in the various branches of reasearch can be gauged by admonishments that what we are witnessing is a new fundamentalism that has simply inverted the terms of the dualism of time and space (May and Thrift 2001: “Introduction”. According to Michael Dear the sway of space is manifested in multifold ways: in the ubiquity of spatial analysis in social theories and practices; in the explosion of publications devoted to the exploration of the interface of the social and the spatial; in the reintegration of human geography into various domains of knowledge; in the focus given to difference and the consequent diversification of theoretical and empirical practices; in a theoretically informed exploration of the relation between geographical knowledge and social action; and, finally, in the unprecedented proliferation of research agendas and publications pertaining to these isuuses (Dear 2001: 24. Two recent collections of papers are indicative of the ubiquity of spatial issues in scholarly work.

  18. Linguistic analysis of suicide notes in Spain

    Directory of Open Access Journals (Sweden)

    Mercedes Fernández-Cabana

    Full Text Available Background and Objectives: Text analysis software like "Linguistic Inquiry and Word Count" (LIWC has been used for the analysis of suicide notes and suicidal texts in English. This is the first analysis of suicide notes using this method in Spanish and, as far as we know, its first application to suicide notes in Europe. To compare the sociodemographic and forensic characteristics of a consecutive sample of suicide victims studying the differences between those who left suicidal note and those who did not. To study a sample of suicidal notes from Spain using LIWC, comparing it's linguistic features by gender, age and environment. Methods: 144 consecutive suicide cases were analyzed. 23 suicide notes obtained from this sample were processed using LIWC, the results were compared by gender, age and environment of the author. Results: People who left suicide notes were younger than non- writers; more frequently single, divorced or widowed and emotional troubles were reported as frequent triggers. Suicide notes written by women were significantly longer, had more emotional content, tentative expressions, denials, pronouns in first person plural and verbs in past and future tenses. Urban cases showed higher emotional expression and word complexity whereas rural cases showed a higher use of social words. Conclusions: Our study shows some differences between people who left suicide note and those who didn't and confirms the LIWC ability to detect differences in suicidal speech by gender and by the rural/ urban background of its authors.

  19. Station Program Note Pull Automation

    Delgado, Ivan

    2016-01-01

    Upon commencement of my internship, I was in charge of maintaining the CoFR (Certificate of Flight Readiness) Tool. The tool acquires data from existing Excel workbooks on NASA's and Boeing's databases to create a new spreadsheet listing out all the potential safety concerns for upcoming flights and software transitions. Since the application was written in Visual Basic, I had to learn a new programming language and prepare to handle any malfunctions within the program. Shortly afterwards, I was given the assignment to automate the Station Program Note (SPN) Pull process. I developed an application, in Python, that generated a GUI (Graphical User Interface) that will be used by the International Space Station Safety & Mission Assurance team here at Johnson Space Center. The application will allow its users to download online files with the click of a button, import SPN's based on three different pulls, instantly manipulate and filter spreadsheets, and compare the three sources to determine which active SPN's (Station Program Notes) must be reviewed for any upcoming flights, missions, and/or software transitions. Initially, to perform the NASA SPN pull (one of three), I had created the program to allow the user to login to a secure webpage that stores data, input specific parameters, and retrieve the desired SPN's based on their inputs. However, to avoid any conflicts with sustainment, I altered it so that the user may login and download the NASA file independently. After the user has downloaded the file with the click of a button, I defined the program to check for any outdated or pre-existing files, for successful downloads, to acquire the spreadsheet, convert it from a text file to a comma separated file and finally into an Excel spreadsheet to be filtered and later scrutinized for specific SPN numbers. Once this file has been automatically manipulated to provide only the SPN numbers that are desired, they are stored in a global variable, shown on the GUI, and

    2004-01-01

    This paper reports on a small-scale empirical study on note-taking in consecutive interpreting. As data, the study draws on the notes produced by four subjects while interpreting one Spanish source text consecutively into Danish, on the one hand, and one Danish source text into Spanish......, on the other. The aim of the study is to explore what governs conference interpreters' choice of language for their notes. The categories traditionally used to discuss, describe and explain this choice are those of 'source language' and 'target language', and these categories are therefore subject...... to particular scrutiny here. However, somewhat surprisingly, the results of the analyses indicate that the choice of language in note-taking is governed mainly by the status of the language in the interpreters' language combination, i.e. whether it is an A- or a B-language, and much less by its status...

    Bohay, Mark; Blakely, Daniel P; Tamplin, Andrea K; Radvansky, Gabriel A

    2011-01-01

    In previous work assessing memory at various levels of representation, namely the surface form, textbase, and situation model levels, participants read texts but were otherwise not actively engaged with the texts. The current study tested the influence of active engagement with the material via note taking, along with the opportunity to review such notes, and the modality of presentation (text vs. spoken). The influence of these manipulations was assessed both immediately and 1 week later. In Experiment 1 participants read a text, whereas in Experiment 2 participants watched a video recording of the material being read as a lecture. For each experiment the opportunity to take notes was manipulated within participants, and the opportunity to review these notes before the test was manipulated between participants. Note taking improved performance at the situation model level in both experiments, although there was also some suggestion of benefit for the surface form. Thus, active engagement with material, such as note taking, appears to have the greatest benefit at the deeper levels of understanding.

    2010-01-01

    Electron microscopy (EM) has long been indispensable for flatworm research, as most of these worms are microscopic in dimension and provide only a handful of characters recognizable by eye or light microscopy. Therefore, major progress in understanding the histology, systematics, and evolution of this animal group relied on methods capable of visualizing ultrastructure. The rise of molecular and cellular biology renewed interest in such ultrastructural research. In the light of recent developments, we offer a best-practice guide for users of transmission EM and provide a comparison of well-established chemical fixation protocols with cryo-processing methods (high-pressure freezing/freeze-substitution, HPF/FS). The organisms used in this study include the rhabditophorans Macrostomum lignano, Polycelis nigra and Dugesia gonocephala, as well as the acoel species Isodiametra pulchra.

    Egger, Bernhard; Gschwentner, Robert; Rieger, Reinhard

    2007-02-01

    Traditionally, regeneration research has been closely tied to flatworm research, as flatworms (Plathelminthes) were among the first animals where the phenomenon of regeneration was discovered. Since then, the main focus of flatworm regeneration research was on triclads, for which various phenomena were observed and a number of theories developed. However, free-living flatworms encompass a number of other taxa where regeneration was found to be possible. This review aims to display and to compare regeneration in all major free-living flatworm taxa, with special focus on a new player in the field of regeneration, Macrostomum lignano (Macrostomorpha). Findings on the regeneration capacity of this organism provide clues for links between regeneration and (post-)embryonic development, starvation, and asexual reproduction. The role of the nervous system and especially the brain for regeneration is discussed, and similarities as well as particularities in regeneration among free-living flatworms are pointed out.

    The creation of medical notes in software applications poses an intrinsic problem in workflow as the technology inherently intervenes in the processes of collecting and assembling information, as well as the production of a data-driven note that meets both individual and healthcare system requirements. In addition, the note writing applications in currently available electronic health records (EHRs) do not function to support decision making to any substantial degree. We suggest that artificial intelligence (AI) could be utilized to facilitate the workflows of the data collection and assembly processes, as well as to support the development of personalized, yet data-driven assessments and plans. ©Rodrigo Octávio Deliberato, Leo Anthony Celi, David J Stone.

  14. A Comparison of Suicide Note Writers with Suicides Who Did Not Leave Notes

    Callanan, Valerie J.; Davis, Mark S.

    2009-01-01

    There is disagreement in the suicide literature on the value of suicide notes as a data source, particularly regarding the extent to which suicide decedents who write notes differ from those who do not. Using 10 years of suicide cases from Summit County, Ohio, these two groups were compared on 40 variables including sociodemographic…

  15. The impact of note taking style and note availability at retrieval on mock jurors' recall and recognition of trial information.

    Science.gov (United States)

    Thorley, Craig; Baxter, Rebecca E; Lorek, Joanna

    2016-01-01

    Jurors forget critical trial information and what they do recall can be inaccurate. Jurors' recall of trial information can be enhanced by permitting them to take notes during a trial onto blank sheets of paper (henceforth called freestyle note taking). A recent innovation is the trial-ordered-notebook (TON) for jurors, which is a notebook containing headings outlining the trial proceedings and which has space beneath each heading for notes. In a direct comparison, TON note takers recalled more trial information than freestyle note takers. This study investigated whether or not note taking improves recall as a result of enhanced encoding or as a result of note access at retrieval. To assess this, mock jurors watched and freely recalled a trial video with one-fifth taking no notes, two-fifths taking freestyle notes and two-fifths using TONs. During retrieval, half of the freestyle and TON note takers could access their notes. Note taking enhanced recall, with the freestyle note takers and TON note takers without note access performing equally as well. Note taking therefore enhances encoding. Recall was greatest for the TON note takers with note access, suggesting a retrieval enhancement unique to this condition. The theoretical and applied implications of these findings are discussed.

    Subhas, Gokulakkrishna; Gupta, Aditya; Jacobs, Michael J.; Decker, Melissa; Silberberg, Boris; Mittal, Vijay K.

    2012-01-01

    Background and Objectives: The optimal access route and method for natural orifice transluminal endoscopic surgery (NOTES) has not been established. A transvesical approach, with its low rate of peritoneal contamination, is an effective clean portal of entry, but a safe urinary bladder closure has been a challenge. We developed a new technique for a safe, pure transvesical NOTES approach. Methods: Four female piglets were used in the study. With the pigs under anesthesia, a flexible cystoscope (15Fr) was used to make an endoscopic cystotomy; diagnostic peritoneoscopy of the abdominal quadrants was done with biopsies and hemostasis. At the end, a Vicryl loop was pushed to close the bladder incision while the incision edges were pulled inwards. The pigs were euthanized after 2 wk, and necropsies were performed. Results: No bowel injury was noted in any of the 4 pigs. Satisfactory bladder closure was done in 2 pigs, while a partial closure was achieved in 1 case. In the postoperative period, the pigs showed no signs of pain or distress, voided normally, and had a good appetite. On necropsy, we noted healed cystotomy incisions, no intraabdominal adhesions, and no adhesions at the site. Conclusion: Our new technique for endoscopic cystotomy overcomes previously reported risks for bowel injuries. Using this route gives good spatial orientation and access to all quadrants, including the pelvis. Biopsies with good hemostasis can be easily achieved. Lack of intraperitoneal changes postoperatively indicate that this procedure may be safe for humans. PMID:23484572

  6. Molecular gastronomy is a scientific discipline, and note by note cuisine is the next culinary trend

    Directory of Open Access Journals (Sweden)

    This Hervé

    2013-01-01

    Full Text Available Abstract For the past two decades, there has been much confusion about molecular gastronomy. This confusion has arisen because people ignore that the word gastronomy does not mean cuisine, it means knowledge about food. Similar to ‘molecular biology’, molecular gastronomy is a scientific discipline that looks for the mechanisms of phenomena occurring during dish preparation and consumption. As with any other scientific discipline, it can have many applications. One of the first was ‘molecular cuisine’ but since 1994, ‘note by note cuisine’ has also been promoted. The latter involves preparing dishes using pure compounds, or more practically mixture of compounds obtained by fractioning plant or animal tissues, instead of using these tissues themselves. Note by note cuisine raises issues in various fields: science, technology, nutrition, physiology, toxicology and politics.

  7. Lecture Notes on Network Information Theory

    CERN Document Server

    Gamal, Abbas El

    2010-01-01

    Network information theory deals with the fundamental limits on information flow in networks and optimal coding techniques and protocols that achieve these limits. It extends Shannon's point-to-point information theory and the Ford--Fulkerson max-flow min-cut theorem to networks with multiple sources and destinations, broadcasting, interference, relaying, distributed compression and computing. Although a complete theory is yet to be developed, several beautiful results and techniques have been developed over the past forty years with potential applications in wireless communication, the Internet, and other networked systems. This set of lecture notes, which is a much expanded version of lecture notes used in graduate courses over the past eight years at Stanford, UCSD, CUHK, UC Berkeley, and EPFL, aims to provide a broad coverage of key results, techniques, and open problems in network information theory. The lectures are organized in a "top-down" manner into four parts: background, single-hop networks, multi...

    2010-01-01

    Flatland, Edwin Abbott Abbott's story of a two-dimensional universe, as told by one of its inhabitants who is introduced to the mysteries of three-dimensional space, has enjoyed an enduring popularity from the time of its publication in 1884. This fully annotated edition enables the modern-day reader to understand and appreciate the many "dimensions" of this classic satire. Mathematical notes and illustrations enhance the usefulness of Flatland as an elementary introduction to higher-dimensional geometry. Historical notes show connections to late-Victorian England and to classical Greece. Citations from Abbott's other writings as well as the works of Plato and Aristotle serve to interpret the text. Commentary on language and literary style includes numerous definitions of obscure words. An appendix gives a comprehensive account of the life and work of Flatland's remarkable author.

  20. Synaesthesia for reading and playing musical notes.

    Science.gov (United States)

    Ward, Jamie; Tsakanikos, Elias; Bray, Alice

    2006-02-01

    This study reports three cases of synaesthesia who experience colors in response to written musical notation, graphemes and heard music. The synaesthetes show Stroop-like interference when asked to name the colour of graphemes but not for written musical notes. However, reliable interference is found in two further studies that require deeper processing of the musical notation (namely playing music from colored notation, and naming the synaesthetic color of the notes whilst suppressing the veridical color). This is the first empirical demonstration of synaesthesia for musical notation. The fact that synaesthetic color influences music playing/reading (a sensory-motor transformation) but not verbal color naming suggests that synaesthetic Stroop effects can arise from processing the meaning of a stimulus and not just as a result of verbal response interference. However, it is likely that the color associations themselves have a developmental origin in the names assigned to them. In all three cases, the colors of the written notes are related to the graphemes that arbitrarily denote them (e.g., 'A' may be "red" both as a letter and when written in musical notation). The results suggest that synaesthetic associations may migrate from one representational format (e.g., graphemes) to another (e.g., musical notation).

  3. A Note On Higher Order Grammar

    CERN Document Server

    Gluzberg, Victor

    2009-01-01

    Both syntax-phonology and syntax-semantics interfaces in Higher Order Grammar (HOG) are expressed as axiomatic theories in higher-order logic (HOL), i.e. a language is defined entirely in terms of provability in the single logical system. An important implication of this elegant architecture is that the meaning of a valid expression turns out to be represented not by a single, nor even by a few "discrete" terms (in case of ambiguity), but by a "continuous" set of logically equivalent terms. The note is devoted to precise formulation and proof of this observation.

  4. A note on the microeconomics of migration.

    Stahl, K

    1983-11-01

    "The purpose of this note is to demonstrate in a simple model that an individual's migration from a small town to a large city may be rationalized purely by a consumption motive, rather than the motive of obtaining a higher income. More specifically, it is shown that in a large city an individual may derive a higher utility from spending a given amount of income than in a small town." A formal model is first developed that includes the principal forces at work and is then illustrated using a graphic example. The theoretical and empirical issues raised are considered in the concluding section.

    In this short note, Monte Carlo tests of goodness of fit for data of the form X(t), t ∈ I are considered, that reject the null hypothesis if X(t) leaves an acceptance region bounded by an upper and lower curve for some t in I. A construction of the acceptance region is proposed that complies to a...... to a given target level of rejection, and yields exact p-values. The construction is based on pointwise quantiles, estimated from simulated realizations of X(t) under the null hypothesis....

    2016-01-01

    These pedagogical lecture notes address to the students in theoretical physics for helping them to understand the mechanisms of the linear operators defined on finite-dimensional vector spaces equipped with definite or indefinite inner products. The importance of the Dirac conjugation is pointed out presenting its general theory and a version of the Riesz theorem for the indefinite inner product spaces, based on the Dirac-Riesz map that combines the action of the Riesz map with that of the metric operator. The matrix representations of the linear operators on vector spaces with definite or indefinite inner products is also presented.

  9. Lecture notes on 2-dimensional defect TQFT

    CERN Document Server

    2016-01-01

    These notes offer an introduction to the functorial and algebraic description of 2-dimensional topological quantum field theories `with defects', assuming only superficial familiarity with closed TQFTs in terms of commutative Frobenius algebras. The generalisation of this relation is a construction of pivotal 2-categories from defect TQFTs. We review this construction in detail, flanked by a range of examples. Furthermore we explain how open/closed TQFTs are equivalent to Calabi-Yau categories and the Cardy condition, and how to extract such data from pivotal 2-categories.

    2010-01-01

    Objective To give a conceptual description of natural orifice translumenal endoscopic surgery (NOTES), review theearly efforts in the NOTES field, and discuss its challenges and limitations.Data sources The data were retrieved mainly from publications listed in MEDLINE, PubMed and China WanfangDatabase from 2005 to 2009. The search term was "NOTES". Study selection The articles involved in the "NOTES" study were selected and the review articles were excluded from the comparison. Results A marked increase in quantity in articles was shown each year for NOTES studies from 2006 to 2009. Animalexperiments with "NOTES" have been carried out in China from 2007, and two independent "NOTES" procedures onhumans were reported in 2009. Conclusion Although still in its infancy, the "NOTES" procedure is promising as another type of minimally invasivesurgery and favorable alternative to current interventions.

  13. Musical stem completion: humming that note.

    Science.gov (United States)

    Warker, Jill A; Halpern, Andrea R

    2005-01-01

    This study looked at how people store and retrieve tonal music explicitly and implicitly using a production task. Participants completed an implicit task (tune stem completion) followed by an explicit task (cued recall). The tasks were identical except for the instructions at test time. They listened to tunes and were then presented with tune stems from previously heard tunes and novel tunes. For the implicit task, they were asked to sing a note they thought would come next musically. For the explicit task, they were asked to sing the note they remembered as coming next. Experiment 1 found that people correctly completed significantly more old stems than new stems. Experiment 2 investigated the characteristics of music that fuel retrieval by varying a surface feature of the tune (same timbre or different timbre) from study to test and the encoding task (semantic or nonsemantic). Although we did not find that implicit and explicit memory for music were significantly dissociated for levels of processing, we did find that surface features of music affect semanticjudgments and subsequent explicit retrieval.

  1. A note on the Prandtl layers

    CERN Document Server

    Guo, Yan

    2010-01-01

    This note concerns a nonlinear ill-posedness of the Prandtl equation and an invalidity of asymptotic boundary-layer expansions of incompressible fluid flows near a solid boundary. Our analysis is built upon recent remarkable linear ill-posedness results established by G\\'erard-Varet and Dormy [2], and an analysis in Guo and Tice [5]. We show that the asymptotic boundary-layer expansion is not valid for non-monotonic shear layer flows in Sobolev spaces. We also introduce a notion of Weak Lipschitz well-posedness and prove that the nonlinear Prandtl equation is not well-posed in this sense near non-stationary and non-monotonic shear flows. On the other hand, we are able to verify that Oleinik's monotonic solutions are well-posed.

    In this note, we have addressed various issues on zero temperature holographic superfluids. First, inspired by our numerical evidence for the equality between the superfluid density and particle density, we provide an elegant analytic proof for this equality by a boost trick. Second, using not only the frequency domain analysis but also the time domain analysis from numerical relativity, we identify the hydrodynamic normal modes and calculate out the sound speed, which is shown to increase with the chemical potential and saturate to the value predicted by the conformal field theory in the large chemical potential limit. Third, the generic non-thermalization is demonstrated by the fully non-linear time evolution from a non-equilibrium state for our zero temperature holographic superfluid. Furthermore, a conserved Noether charge is proposed in support of this behavior.

  4. Note: Resistance spot welding using a microgripper

    Hwang, G.; Podrzaj, P.; Hashimoto, H.

    2013-10-01

    Interest in thin-film nanostructures as building blocks for nanoelectronics and nanoelectromechanical systems (NEMS) is increasing. Resistance spot welding (RSW) on a nano or micro scale can play a significant role; similar to that of its macro counterpart for forming connections in device assembly processes. This Note presents a novel micron scale RSW technique using a microgripper as mobile spot welding electrodes to assemble ultra-thin film nanostructures. As an example, assembly of three-dimensional helical nanobelt (HNB) based device was successfully demonstrated using the proposed system. The spot-welding process was fully monitored by the built-in capacitive micro force sensor of the microgripper. Experiments show that RSW, using the microgripper, provides a stable electrical contact with sufficient mechanical strength for the construction of devices such as HNB based devices demonstrated here.

  7. Lecture Notes on Quantum Brownian Motion

    CERN Document Server

    Erdos, Laszlo

    2010-01-01

    Einstein's kinetic theory of the Brownian motion, based upon light water molecules continuously bombarding a heavy pollen, provided an explanation of diffusion from the Newtonian mechanics. Since the discovery of quantum mechanics it has been a challenge to verify the emergence of diffusion from the Schr\\"odinger equation. The first step in this program is to verify the linear Boltzmann equation as a certain scaling limit of a Schr\\"odinger equation with random potential. In the second step, one considers a longer time scale that corresponds to infinitely many Boltzmann collisions. The intuition is that the Boltzmann equation then converges to a diffusive equation similarly to the central limit theorem for Markov processes with sufficient mixing. In these lecture notes (prepared for the Les Houches summer school in 2010 August) we present the mathematical tools to rigorously justify this intuition. The new material relies on joint papers with H.-T. Yau and M. Salmhofer.

    Full Text Available Longtemps absent dans les sciences sociales françaises, le terme "postcolonial" apparaît de plus en plus fréquemment dans les publications et programmes de rencontres, sous l'impulsion des débats autour de l'héritage de la colonisation et des "indigènes de la République". Dans ce contexte, cette note présente les principaux traits qui fondent des postcolonial studies telles qu'elles se sont développées dans le monde anglo-saxon depuis une vingtaine d'années. Cette mise au point, à l'usage des géographes entre autres, vise à clarifier les échanges en montrant le décalage entre le post-colonial français et les postcolonial studies.Long ignored by French social sciences, the term "postcolonial" has recently become popular in academic literature and meetings, in relation to the political debate about colonial legacy and 2nd and 3rd immigrants generations (the so-called "indigènes de la République". Yet, although the term is the same ("postcolonial", the meaning it is usually given in France by those who qualify their work as such is quite different from the one it has in the anglo world. In this context, this note aims at clarifying the situation for French geographers and others by presenting briefly some of the main aspects of postcolonial theory.

    2015-01-01

    This book presents, in his own words, the life of Hugo Steinhaus (1887–1972), noted Polish mathematician of Jewish background, educator, and mathematical popularizer. A student of Hilbert, a pioneer of the foundations of probability and game theory, and a contributor to the development of functional analysis, he was one of those instrumental to the extraordinary flowering of Polish mathematics before and after World War I. In particular, it was he who “discovered” the great Stefan Banach. Exhibiting his great integrity and wit, Steinhaus’s personal story of the turbulent times he survived – including two world wars and life postwar under the Soviet heel – cannot but be of consuming interest. His recounting of the fearful years spent evading Nazi terror is especially moving. The steadfast honesty and natural dignity he maintained while pursuing a life of demanding scientific and intellectual enquiry in the face of encroaching calamity and chaos show him to be truly a mathematician for all seasons. ...

After some preliminary notes on methodological issues of interdisciplinarity and on the way of empirical research about the attitude of the public in museums, the article (even taking into account the reactions of the audience in front of Michelangelo's David focuses on the erotic-instinctual elements in the enjoyment of arts, and offers some criticism about the use of the sublimation’s concept. It then speaks about the role and "degrees" of the “Uncanny” and about the dynamics of identification processes in the study of art fruition. It also emphasizes the importance of the "context" of use as a preliminary to the understanding of its mechanisms. The last section is devoted to the problem of emotion considered from the point of view of psychology, art and aesthetics.

  15. Notes on Mayer expansions and matrix models

    Energy Technology Data Exchange (ETDEWEB)

    Bourgine, Jean-Emile, E-mail: jebourgine@apctp.org

    2014-03-15

    Mayer cluster expansion is an important tool in statistical physics to evaluate grand canonical partition functions. It has recently been applied to the Nekrasov instanton partition function of N=2 4d gauge theories. The associated canonical model involves coupled integrations that take the form of a generalized matrix model. It can be studied with the standard techniques of matrix models, in particular collective field theory and loop equations. In the first part of these notes, we explain how the results of collective field theory can be derived from the cluster expansion. The equalities between free energies at first orders is explained by the discrete Laplace transform relating canonical and grand canonical models. In a second part, we study the canonical loop equations and associate them with similar relations on the grand canonical side. It leads to relate the multi-point densities, fundamental objects of the matrix model, to the generating functions of multi-rooted clusters. Finally, a method is proposed to derive loop equations directly on the grand canonical model.

    Let A be aj ×d (0,1) matrix. It is known that ifj = 2k-1is odd, then det(AAT) ≤(j+1)((j+1)d/4j)j; ifj is even, then det(AAT) ≤ (j+1)((j+2)d/4(j+1))j. A is called a regularD-optimal matrix if it satisfies the equality of the above bounds. In this note, it is proved thatifj = 2k - 1 is odd, then A is a regular D-optimal matrix if and only if A is the adjacent matrixof a (2k - 1, k, (j + 1)d/4j)-BIBD; if j = 2k is even, then A is a regular D-optimal matrix ifand only if A can be obtained from the adjacent matrix B of a (2k + 1, k + 1, (j + 2)d/4(j + 1))-BIBD by deleting any one row from B.

  17. NOTES FOR THE CONSTRUCTION OF ENVIRONMENTAL RATIONALITY

    Directory of Open Access Journals (Sweden)

    Munir Jorge Felício

    2015-12-01

    Full Text Available The notes for the construction of Environmental Rationality proposed in this text were gathered from a contribution of an analysis of phenomenology, epistemology, and ontology relating to Marx. This initiative aims to broaden and deepen the understanding of environmental issues whose global changes raise challenges, especially for the scientific community. It is to question the development of the economic rationality from the degradation of natural resources engendered by the current socio-economic development model. This model is based on the increase of productivity, technological expansion and maintains the norm as if natural resources were still considered abundant and limitless. The transition of this Environmental Rationality is a development sought by using the knowledge gained from the analysis possibilities of phenomenology. Among these possibilities, the indicated interdisciplinary schools of thought, as required by epistemology, can become an interesting research strategy, since it has as the starting point the external demands, where the elements of the current environmental issue exist, and its consequences.

    Quance, Margaret Ann

    2016-08-24

    Anecdotal notes are a method of providing formative feedback to nursing students following clinical experiences. The extant literature on anecdotal notes is written only from the educator perspective, focusing on rationale for and methods of production, rather than on evaluation of effectiveness. A retrospective descriptive study was carried out with a cohort of 283 third year baccalaureate nursing students to explore their perceptions of anecdotal notes as effective formative feedback. The majority of students valued verbal as well as anecdotal note feedback. They preferred to receive feedback before the next learning experience. Students found the quality of feedback varied by instructor. The anecdotal note process was found to meet identified formative feedback requirements as well as the nursing program's requirement for transparency of evaluation and due process. It is necessary to provide professional development to clinical nurse educators to assist them develop high quality formative feedback using anecdotal notes.

  20. Digital Note-Taking: Discussion of Evidence and Best Practices.

    2016-03-01

    Balancing active course engagement and comprehension with producing quality lecture notes is challenging. Although evidence suggests that handwritten note-taking may improve comprehension and learning outcomes, many students still self-report a preference for digital note-taking and a belief that it is beneficial. Future research is warranted to determine the effects on performance of digitally writing notes. Independent of the methods or software chosen, best practices should be provided to students with information to help them consciously make an educated decision based on the evidence and their personal preference. Optimal note-taking requires self-discipline, focused attention, sufficient working memory, thoughtful rewording, and decreased distractions. Familiarity with the tools and mediums they choose will help students maximize working memory, produce better notes, and aid in their retention of material presented.

  4. Planet-B: Technical notes and drawings

    Carignan, George R.

    1996-01-01

    The design of the transformer designated as T101 (061-0351) in the Filament/Bias module (061-0119) in the Planet-B NMS instrument was verified because of the differences from the GCMS and INMS instrument designs. A breadboard of a representation of the Hybrid 2301065, Bias Drive A driving a 2N3700 NPN transistor, with dual 75V secondaries, with loads, was used to test the circuit. The initial transformer design that was wound with bifilar secondaries was too unstable to test. The second 1408 transformer with a split bobbin and the feedback winding below the primary was also found to be unstable. (It was nearly impossible to keep the circuit from squeeging). The third transformer tested has the feedback on the outside of the resonant winding. The primary goal of the design was to have as tight a magnetic coupling as possible to the resonant winding, and as loose a coupling as possible to the primary. Further, the circuit AC ground is connected to the winding at the feedback end of the secondary winding. This transformer proved to be very stable - it is virtually impossible to make this design squeg. An emitter resistor (Rl29A) was added to this circuit, as referenced to the GCMS design, to protect Q102 from thermal runaway in the event of a turn on with a non- resonate circuit or load short. This was verified to protect Q102 for at least 30 seconds in the event of a short. Approximately 1% of the 4lmW input power is lost in this protection resistor under normal operation. The circuit was verified to operate normally when a radiated Q102 (2N3700), (low Beta) transistor was substituted for the normal 2N3700. It should be noted that the monitored drive voltage went to approximately 2.7V with this low gain transistor.

  5. Note a margine del fenomeno migratorio

    Full Text Available Abstract – The phenomenon of migration is one of the things which has had the greatest influence on the history of humanity, involving millions of people. Today men and women of all ages, mostly young people from economically disadvantaged areas of the planet, migrate from one continent to another, for economic, political or religious reasons. They move towards geopolitical areas which are economically and politically less troubled, leaving others where the living conditions are no longer possible. In some cases, it is a question of looking for better conditions of existence (economic causes; in other cases of mere survival (political and religious causes. Both for operational reasons and of interpretation, it is necessary to distinguish between the causes of expulsion and the consequent migration types. It is important to understand whether we are facing migration of a political or an economic nature, but it should be noted, also, that it is increasingly difficult to distinguish between politics and economics. It is a movement that creates upheaval and irreversible processes in both the countries of departure and destination. We are therefore facing a historical process of enormous importance that contributes to change the human geography and the international scene. We are facing two large economic and political areas: one of expulsion and another of attraction, with two very different types of living conditions. Every generation enjoys a condition of life and existence merely because it is born in one place rather than in another; an ascribed status that can even prevent attempts at all forms of mobility. A geographical area that is seeing its attractiveness increase is that of the EU; partly because of its colonial history, but also because of its geo-economic-political position, and also recently because of the upheavals following the fall of regimes in Eastern Europe and in the Middle East.

  6. POEM, the Prototypical "New NOTES" Procedure and First Successful NOTES Procedure.

    Science.gov (United States)

    Bechara, Robert; Inoue, Haruhiro

    2016-04-01

    Peroral endoscopic myotomy (POEM) was first performed in 2008 as a novel treatment of achalasia. It is now performed globally, demonstrating the evolution of the first successful natural orifice transluminal endoscopic surgery (NOTES) procedure. There is extensive data demonstrating the safety and efficacy of POEM, and now long-term data has emerged demonstrating that the efficacy is durable. POEM is also being used to successfully treat diffuse esophageal spasm (DES) and jackhammer esophagus. With jackhammer esophagus and DES, inclusion of the lower esophageal sphincter in the myotomy minimizes the risk of symptom development from iatrogenic ineffective esophageal motility.

  18. NOTES ON IMAGES TO TEACH GEOGRAPHY

    Directory of Open Access Journals (Sweden)

    Ivaine Maria Tonini

    2013-12-01

    Full Text Available This paper aims at providing notes on images of identities regarded as others in our society. My own academic research starting on with my Geography textbook and cut through by media was the guiding thread I have chosen. We aim at having a critical gaze upon what guides the subject, divides, separates, ranks, normalises, territorialises, and makes meanings of subjects. Based on this assumption, reflections show pros and cons of the textbook in contemporary times, a period of deep changes in the way of being and learning. as meanings inscribed in textbooks are close to lifeworld, students’ everyday life, as they have the same meanings in other places: TV, newspapers, magazines, ads, internet, these images do not belong only to the classroom during reading. Outside of school they are drives for these students’ cultural practices. What one learns with image-inscribed meanings they bring to their everyday life, there is no border between what these students learn in school and their ways of being in society. Finally, I have found out that other meanings are not in these images in these times, discourse sameness barring other meanings, even with so many affirmatives education policies have introduced. This strongly visualised discursive permanence must be urgently investigated. RESUMO: Este texto tem a intenção de estabelecer algumas notas sobre as imagens de identidades posicionadas como ‘Outras’ na nossa sociedade. O fio condutor escolhido foi minha trajetória de pesquisa acadêmica, iniciada pelo livro didático de Geografia e permeada pela mídia. Objetiva-se produzir uma analítica do olhar, que conduza pelos seus enunciados uma reflexão sobre aquilo que nomeia o sujeito. Isto permite a constatar o que divide, separa, categoriza, normaliza, territorializa as identidades e, consequentemente, produz significados sobre os sujeitos.

  20. Melanie Klein and countertransference: a note on some archival material.

    Science.gov (United States)

    Hinshelwood, R D

    2008-01-01

    Five pages of notes were found in the Melanie Klein Archives at the Wellcome Library that concern her views on countertransference in 1953. Because of the paucity of references to countertransference in Klein's published writings these Notes fill in out knowledge. Her views were provoked by the work her students were doing in their experimental analyses of schizophrenic patients. Apocryphal stories suggest that Klein remained aligned with Freud's view of countertransference as simply interference. The Notes confirm that, whilst there is some truth to that, she did have a more sophisticated and nuanced view of the unconscious relations between analyst and analysand.

    Denny, Joshua C; Miller, Randolph A; Johnson, Kevin B; Spickard, Anderson

    2008-11-06

    Clinical documentation is often expressed in natural language text, yet providers often use common organizations that segment these notes in sections, such as history of present illness or physical examination. We developed a hierarchical section header terminology, supporting mappings to LOINC and other vocabularies; it contained 1109 concepts and 4332 synonyms. Physicians evaluated it compared to LOINC and the Evaluation and Management billing schema using a randomly selected corpus of history and physical notes. Evaluated documents contained a median of 54 sections and 27 major sections. There were 16,196 total sections in the evaluation note corpus. The terminology contained 99.9% of the clinical sections; LOINC matched 77% of section header concepts and 20% of section header strings in those documents. The section terminology may enable better clinical note understanding and interoperability. Future development and integration into natural language processing systems is needed.

    We present U-Note, an augmented teaching and learning system leveraging the advantages of paper while letting teachers and pupils benefit from the richness that digital media can bring to a lecture. U-Note provides automatic linking between the notes of the pupils' notebooks and various events that occurred during the class (such as opening digital documents, changing slides, writing text on an interactive whiteboard...). Pupils can thus explore their notes in conjunction with the digital documents that were presented by the teacher during the lesson. Additionally, they can also listen to what the teacher was saying when a given note was written. Finally, they can add their own comments and documents to their notebooks to extend their lecture notes. We interviewed teachers and deployed questionnaires to identify both teachers and pupils' habits: most of the teachers use (or would like to use) digital documents in their lectures but have problems in sharing these resources with their pupils.

  19. The concept of disclosure in the notes to financial statements

    Directory of Open Access Journals (Sweden)

    A.V. Ozeran

    2015-12-01

    Full Text Available The notes to Financial Statements are one of the most powerful sources of information for management decisions concerning a business entity. The tendency to overload informative notes causes rethinking of their role and content. The aim of the study is to discuss a number of ideas that set the requirements for disclosure in the notes to financial statements in order to prevent duplication of information in financial reporting as a whole and eliminate irrelevant disclosure to achieve clarity, consistency and effectiveness of the information contained in the notes. Based on the proposed clarified definition of «the notes to financial statements», we concluded that the notes should: a provide details and explanations of primary financial statements; b apply only to transactions and events existing at the reporting date; c focus on the needs of specific users and reflect reporting information specific to each entity. The development of the paper concepts will help strengthen the usefulness of company financial statements and increase their transparency.

  1. Lexical Means in Communicating Emotion in Suicide Notes – on the Basis of the Polish Corpus of Suicide Notes

    Directory of Open Access Journals (Sweden)

    Monika Zaśko-Zielińska

    2015-12-01

    Full Text Available Lexical Means in Communicating Emotion in Suicide Notes - on the Basis of the Polish Corpus of Suicide Notes Polish Corpus of Suicide Notes (PCSN is a relatively large set of authentic suicide notes that are linguistically annotated on several levels. In order to identify features characteristic for this genre we compared PCSN with the collected subcorpus of counterfeited suicide notes. In this paper we focus on the lexical means of expressing emotions. Our goal was to analyse ways of expressing emotions in this specific genre. Our initial list of lexical markers was based on Markowski’s list of the lexis common for different genres. The list was next expanded with the help of the plWordNet 2.0 — a lexico-semantic network. The expansion was based on the manually selected noun and verb hypernymy branches according to their correspondence to the elements of the initial list. For words from the extended list, a quantitative analysis was performed for both authentic and fake suicide notes. We have also analysed the use of the lexical markers of emotions, feelings and emotional states, as well as emotion operators, and ways of expressing personal evaluation, affection and hate.

    It is increasingly recognized that redundant information in clinical notes within electronic health record (EHR) systems is ubiquitous, significant, and may negatively impact the secondary use of these notes for research and patient care. We investigated several automated methods to identify redundant versus relevant new information in clinical reports. These methods may provide a valuable approach to extract clinically pertinent information and further improve the accuracy of clinical information extraction systems. In this study, we used UMLS semantic types to extract several types of new information, including problems, medications, and laboratory information. Automatically identified new information highly correlated with manual reference standard annotations. Methods to identify different types of new information can potentially help to build up more robust information extraction systems for clinical researchers as well as aid clinicians and researchers in navigating clinical notes more effectively and quickly identify information pertaining to changes in health states.

    2002-04-01

    Currency producers are facing dual marketplace demands to increase bank note circulation life and to employ increasingly effective security features against counterfeiting. Diffractive optically variable devices such as foil patches, stripes and windowed thread have become popular security features used for bank notes throughout the world, but historically have suffered in their ability to match the durability of the bank note substrate itself. A study to find a durable, diffractive OVD led to the development of a windowed-thread feature designed to pass stringent durability criteria for laundry, chemical soak and other performance tests. Diffractive-film production methods, demetallization techniques, thread construction and applied coatings were key factors in achieving this durability.

    2010-09-01

    Enthusiasm for natural orifice transluminal endoscopic surgery (NOTES) has been partly tempered by the reality that most NOTES procedures to date have been laparoscopically assisted. After safely performing transvaginal cholecystectomy in an IACUC-approved porcine model, the authors embarked on an institution review board (IRB)-approved protocol for ultimate performance of pure NOTES cholecystectomy in humans. They describe their experience performing a true NOTES transvaginal cholecystectomy after safely accomplishing three laparoscopically assisted or hybrid procedures in humans. One of the patients was a 35-year-old woman presenting with symptoms of biliary colic. Ultrasound confirmed gallstones, and her liver enzymes were normal. Pneumoperitoneum to 15 mmHg was obtained via a transvaginal trocar placed through a colpotomy made under direct vision. A double-channel endoscope then was advanced into the abdomen. To overcome the retracting limitations of currently available endoscopes, the authors used an extra-long 5-mm articulating retractor placed into the abdomen via a separate colpotomy made under direct vision using the flexible endoscope in a retroflexed position. Endoscopically placed clips were used for control of both the cystic duct and the artery. These techniques obviated the need for any transabdominally placed instruments or needles. This patient was the first to undergo a completely NOTES cholecystectomy at the authors' institution, and to their knowledge, in the United States. She was discharged on the day of surgery and at this writing has not experienced any complication after 1 month of follow-up evaluation. Performance of NOTES transvaginal cholecystectomy without aid of laparoscopic or needleoscopic instruments is feasible and safe for humans. Additional experience with this technique are required before studies comparing it with standard laparoscopy and hybrid techniques are appropriate.

  18. Salinity stress from the perspective of the energy-redox axis: Lessons from a marine intertidal flatworm

    Directory of Open Access Journals (Sweden)

    Georgina A. Rivera-Ingraham

    2016-12-01

    Full Text Available In the context of global change, there is an urgent need for researchers in conservation physiology to understand the physiological mechanisms leading to the acquisition of stress acclimation phenotypes. Intertidal organisms continuously cope with drastic changes in their environmental conditions, making them outstanding models for the study of physiological acclimation. As the implementation of such processes usually comes at a high bioenergetic cost, a mitochondrial/oxidative stress approach emerges as the most relevant approach when seeking to analyze whole-animal responses. Here we use the intertidal flatworm Macrostomum lignano to analyze the bioenergetics of salinity acclimation and its consequences in terms of reactive oxygen/nitrogen species formation and physiological response to counteract redox imbalance. Measures of water fluxes and body volume suggest that M. lignano is a hyper-/iso-regulator. Higher salinities were revealed to be the most energetically expensive conditions, with an increase in mitochondrial density accompanied by increased respiration rates. Such modifications came at the price of enhanced superoxide anion production, likely associated with a high caspase 3 upregulation. These animals nevertheless managed to live at high levels of environmental salinity through the upregulation of several mitochondrial antioxidant enzymes such as superoxide dismutase. Contrarily, animals at low salinities decreased their respiration rates, reduced their activity and increased nitric oxide formation, suggesting a certain degree of metabolic arrest. A contradictory increase in dichlorofluorescein fluorescence and an upregulation of gluthathione-S-transferase pi 1 (GSTP1 expression were observed in these individuals. If animals at low salinity are indeed facing metabolic depression, the return to seawater may result in an oxidative burst. We hypothesize that this increase in GSTP1 could be a “preparation for oxidative stress”, i

    The operative note needs to be an accurate and legible account of events occurring in the surgeon's theatre. We set out to discover if operative notes within a British District General Oral and Maxillofacial Surgery department adhered to Royal College of Surgeons (England) guidelines. We audited 100 consecutive Oral and Maxillofacial Surgery operations performed within general theatres. As an intervention we designed and piloted a paper based Operative Note Proforma and re-audit was undertaken. Initial audit showed results lacking in certain areas. At re-audit all audit criteria showed improvement. The mean percentage of data point inclusion rose from 76.1 to 98.3% (0.001 Oral and Maxillofacial Surgery.

  7. Molecular Analysis of Bacterial Microbiota on Brazilian Currency Note Surfaces.

    2015-10-22

    Currency notes have been implicated as a vehicle for transmitting community-acquired bacterial infections. However, the overall diversity of the bacterial population residing on banknotes is still unknown in Brazil. In this study, we aimed to investigate the overall bacterial population from 150 different Brazilian Rial (R$) notes in circulation using a culture-independent Illumina massively parallel sequencing approach of the 16S rRNA genes. Samples were randomly collected from three different street markets or "feiras" in the metropolitan region of São Paulo. Taxonomical composition revealed the abundance of Proteobacteria phyla, followed by Firmicutes and Streptophyta, with a total of 1193 bacterial families and 3310 bacterial genera. Most of these bacterial genera are of human, animal, and environmental origins. Also, our analysis revealed the presence of some potential pathogenic bacterial genera including Salmonella, Staphylococcus, and Klebsiella. The results demonstrate that there is a tremendous diversity of bacterial contamination on currency notes, including organisms known to be opportunistic pathogens. One of the factors that may contribute to the richness of bacterial diversity in currency notes is personal hygiene. Thus, our results underscore the need to increase public awareness of the importance of personal hygiene of money handlers who also handle food.

    1998-09-01

    A good reference management program should make it easy to record the elements of a reference: author's name, year of publication, title of article, etc. It should offer tools that let you find and retrieve references quickly, and it should be able to produce the bibliography in the format required for a particular publication. There are many computer programs, but very few stand out as truly useful, time saving, and work enhancing. One of them is EndNote-EndLink. We want to report our experience with this database manager. The functions and the use of the software package EndNote 2.3 for Windows are described. You can create your database or you can download batches of references from one of the popular searching services (e.g. MEDLINE). When you want to cite a reference you simply paste the reference wherever you want your in-text citation to appear. To prepare the bibliography, EndNote scans your article, replaces the place holders with citations and prints the list of references at the end of the manuscript, according with the style that you have chosen. Altogether EndNote provides an excellent combination of features and ease of use.

  4. GOSPEL MOTIVES IN THE DYING NOTES OF NIKOLAI GOGOL

    Directory of Open Access Journals (Sweden)

    Vladimir Dmitrievich Denisov

    2012-11-01

    Full Text Available The article analyses several notes made by Nikolai Gogol shortly before his death in the light of their links to his other works and the Gospel text. The author seems to have understood that he was dying and was preparing to meet his death as a Christian should, to an extent matching the events around him with those in the Gospel. His artistic eye and hand did not fail him. His dying notes feature a brief sketch of a man in a cab and a profile of a man being shut by a closing book. Calligraphic handwriting Gogol had developed by mid-1840s differs from both the large scribble of the draft text of Evenings on a Farm Near Dikanka in the 1830s and the small hand of his historical notes, articles and novellas of the mid-1830s. His new hand was that of a man who knew the value of words, and not of a copyist working with government papers. Overall, the notes are permeated with the mood of contrition and humility. Gogol writes that Satan has already entered the world and the last days are approaching when man is abandoned by God and considers solitude the highest good. He sees his actions as the only true way and takes pride in his sins and ignorance as if they were virtues. The decay of “the temple of his soul” leaves no chance for love and harmony, disconnecting people and ruining the world. Gogol wants to prevent this by uniting people in the Gospel. The longest of his dying notes is addressed to his friends. Every true Christian can be viewed as such.

The research part being omitted, they included a review of the bosonic closed string a la Polyakov and of the one-loop background field method of quantisation defined through the zeta-function. In an appendix some basic features of the Riemann zeta-function are also reviewed. The pedagogical aspects of the material here presented are particularly emphasized. These notes are used, together with the Scherk's article in Rev. Mod. Phys. and the first volume of the Polchinski book, for the mini-course on String Theory (16-hours of lectures) held at CBPF.

    Dritz, K. W.

    1975-11-01

    Presented here are notes for a course in PL/I. They might serve as a guide to those who are developing a course, or as class notes for that course. They might be useful as a textbook independent of any course; as such a textbook, however, they are not self-contained because of the built-in assumption that they will supplement lectures and be accompanied by manuals. Very nearly the full language is taught here, with the emphasis on concepts rather than practical details. Discussion of I/O is avoided until roughly the midpoint of the course. The hoped-for consequence for students is an enhanced perception and understanding of the many concepts and their logical relationships. The dawning of the age of transportability for PL/I programs gives the user a reason, for the first time, to avoid convenient but illegal language.

  10. Martyrs' last letters: are they the same as suicide notes?

    Science.gov (United States)

    Leenaars, Antoon A; Ben Park, B C; Collins, Peter I; Wenckstern, Susanne; Leenaars, Lindsey

    2010-05-01

    Of the 800,000 suicides worldwide every year, a small number fall under Emile Durkheim's term of altruistic suicides. Study on martyrdom has been limited. There has to date, for example, been no systematic empirical study of martyr letters. We examined 33 letters of Korean self-immolators, compared with 33 suicide notes of a matched sample of more common suicides. An analysis of intrapsychic factors (suicide as unbearable pain, psychopathology) and interpersonal factors (suicide as murderous impulses and need to escape) revealed that, although one can use the same psychological characteristics or dynamics to understand the deaths, the state of mind of martyrs is more extreme, such that the pain is reported to be even more unbearable. Yet, there are differences, such as there was no ambivalence in the altruistic notes. It is concluded that intrapsychic and interpersonal characteristics are central in understanding martyrs, probably equal to community or societal factors. More forensic study is, however, warranted.

  12. A note on the "word-order problem" in agrammatism.

    Science.gov (United States)

    Caplan, D

    1983-09-01

    This brief note has two parts. First, it presents an analysis of the ability of English agrammatic patients to assign the thematic roles of agent, instrument, theme, and locative to noun phrases in active and passive sentences and prepositional phrases. Data regarding this ability have been presented by Schwartz, Saffran, and Marin (Brain and Language, 10, 149-262 (1980) regarding comprehension, and by Saffran, Schwartz, and Marin (Brain and Language, 10, 263-280 (1980) regarding production. These authors claim their data show that English agrammatic aphasics do not map "word order" onto thematic information. However, a very simple set of principles accounts for all their results, including results which are discrepant in their treatment, but requires that English agrammatics assign thematic roles to NPs in part by virtue of the position of an NP in a sentence or a phrase. In the second part of this note, several issues raised by this re-analysis are briefly discussed.

    This paper reports on a shared task involving the assignment of emotions to suicide notes. Two features distinguished this task from previous shared tasks in the biomedical domain. One is that it resulted in the corpus of fully anonymized clinical text and annotated suicide notes. This resource is permanently available and will (we hope) facilitate future research. The other key feature of the task is that it required categorization with respect to a large set of labels. The number of participants was larger than in any previous biomedical challenge task. We describe the data production process and the evaluation measures, and give a preliminary analysis of the results. Many systems performed at levels approaching the inter-coder agreement, suggesting that human-like performance on this task is within the reach of currently available technologies.

    Kotakemori et al. [H. Kotakemori, K. Harada, M. Morimoto, H. Niki, A comparison theorem for the iterative method with the preconditioner (I+Smax), Journal of Computational and Applied Mathematics 145 (2002) 373-378] have reported that the convergence rate of the iterative method with a preconditioner Pm=(I+Sm) was superior to one of the modified Gauss-Seidel method under the condition. These authors derived a theorem comparing the Gauss-Seidel method with the proposed method. However, through application of a counter example, Wen Li [Wen Li, A note on the preconditioned GaussSeidel (GS) method for linear systems, Journal of Computational and Applied Mathematics 182 (2005) 81-91] pointed out that there exists a special matrix that does not satisfy this comparison theorem. In this note, we analyze the reason why such a to counter example may be produced, and propose a preconditioner to overcome this problem.

  16. A note on calculating the optimal risky portfolio

    OpenAIRE

    Reha H. Tütüncü

    2001-01-01

    Given a number of risky assets and a riskless asset, the set of efficient portfolios in the mean-variance optimization sense are combinations of the riskless asset and a unique optimal risky portfolio. This note shows how a simple modification of Markowitz' method of critical lines can be used to determine the optimal risky portfolio in a faster, more reliable, and more memory-efficient way than the standard approaches.

    In this note we remark that the butterfly effect can be used to diagnose the phase transition of superconductivity in a holographic framework. Specifically, we compute the butterfly velocity in a charged black hole background as well as anisotropic backgrounds with Q-lattice structure. In both cases we find its derivative to the temperature is discontinuous at critical points. We also propose that the butterfly velocity can signalize the occurrence of thermal phase transition in general holographic models.

    2014-02-10

    Lin's concordance correlation coefficient (CCC) is a very popular scaled index of agreement used in applied statistics. To obtain a confidence interval (CI) for the estimate of CCC, jackknifing was proposed and shown to perform well in simulation as well as in applications. However, a theoretical proof of the validity of the jackknife CI for the CCC has not been presented yet. In this note, we establish a sufficient condition for using the jackknife method to construct the CI for the CCC.

  5. Absolute pitch: effects of timbre on note-naming ability.

    Directory of Open Access Journals (Sweden)

    Patrícia Vanzella

    Full Text Available BACKGROUND: Absolute pitch (AP is the ability to identify or produce isolated musical tones. It is evident primarily among individuals who started music lessons in early childhood. Because AP requires memory for specific pitches as well as learned associations with verbal labels (i.e., note names, it represents a unique opportunity to study interactions in memory between linguistic and nonlinguistic information. One untested hypothesis is that the pitch of voices may be difficult for AP possessors to identify. A musician's first instrument may also affect performance and extend the sensitive period for acquiring accurate AP. METHODS/PRINCIPAL FINDINGS: A large sample of AP possessors was recruited on-line. Participants were required to identity test tones presented in four different timbres: piano, pure tone, natural (sung voice, and synthesized voice. Note-naming accuracy was better for non-vocal (piano and pure tones than for vocal (natural and synthesized voices test tones. This difference could not be attributed solely to vibrato (pitch variation, which was more pronounced in the natural voice than in the synthesized voice. Although starting music lessons by age 7 was associated with enhanced note-naming accuracy, equivalent abilities were evident among listeners who started music lessons on piano at a later age. CONCLUSIONS/SIGNIFICANCE: Because the human voice is inextricably linked to language and meaning, it may be processed automatically by voice-specific mechanisms that interfere with note naming among AP possessors. Lessons on piano or other fixed-pitch instruments appear to enhance AP abilities and to extend the sensitive period for exposure to music in order to develop accurate AP.

    The conjugate gradient method for unconstrained optimization problems varies with a scalar. In this note, a general condition concerning the scalar is given, which ensures the global convergence of the method in the case of strong Wolfe line searches. It is also discussed how to use the result to obtain the convergence of the famous Fletcher-Reeves, and Polak-Ribiere-Polyak conjugate gradient methods. That the condition cannot be relaxed in some sense is mentioned.

    General formulas for Hansen's coefficients in satellite theory are derived along with expressions for the eccentricity functions G and H. Recurrence relations for the eccentricity functions and their derivatives are obtained which are valid for all values of the parameter p. It is noted that the recurrence relations obtained by Challe and Laclaverie (1969) as well as by Balmino (1973) do not satisfy certain parity conditions and therefore involve coefficients outside the range of usage.

    The 91 segments of the SALT primary need to be kept precisely aligned in order to obtain the best images. As is well-known, the initial alignment process uses a type of Shack-Hartmann wavefront sensor in an auxiliary tower to send feedback to control the mirror actuators. This note reveals the success of new edge-sensors that keep the mirrors in alignment for several days at a time without the need for Shack-Hartmann testing.

  15. Redundancy-aware topic modeling for patient record notes.

    Directory of Open Access Journals (Sweden)

    Raphael Cohen

    Full Text Available The clinical notes in a given patient record contain much redundancy, in large part due to clinicians' documentation habit of copying from previous notes in the record and pasting into a new note. Previous work has shown that this redundancy has a negative impact on the quality of text mining and topic modeling in particular. In this paper we describe a novel variant of Latent Dirichlet Allocation (LDA topic modeling, Red-LDA, which takes into account the inherent redundancy of patient records when modeling content of clinical notes. To assess the value of Red-LDA, we experiment with three baselines and our novel redundancy-aware topic modeling method: given a large collection of patient records, (i apply vanilla LDA to all documents in all input records; (ii identify and remove all redundancy by chosing a single representative document for each record as input to LDA; (iii identify and remove all redundant paragraphs in each record, leaving partial, non-redundant documents as input to LDA; and (iv apply Red-LDA to all documents in all input records. Both quantitative evaluation carried out through log-likelihood on held-out data and topic coherence of produced topics and qualitative assessment of topics carried out by physicians show that Red-LDA produces superior models to all three baseline strategies. This research contributes to the emerging field of understanding the characteristics of the electronic health record and how to account for them in the framework of data mining. The code for the two redundancy-elimination baselines and Red-LDA is made publicly available to the community.

    Cushing, J M; Diekmann, Odo

    2016-09-01

    The basic reproduction number R0 is, by definition, the expected life time number of offspring of a newborn individual. An operationalization entails a specification of what events are considered as "reproduction" and what events are considered as "transitions from one individual-state to another". Thus, an element of choice can creep into the concretization of the definition. The aim of this note is to clearly expose this possibility by way of examples from both population dynamics and infectious disease epidemiology.

    Demirci, Serafettin; Dogan, Kamil Hakan; Erkol, Zerrin; Gunaydin, Gursel

    2009-09-01

    Suicide notes are commonly written on some materials, such as notebooks, papers, and mirrors. Additionally, suicide plans have been communicated in face-to-face conversations, by speaking on the telephone, recording on CDs or video cassettes, and sending messages through text messaging. In this article, 2 suicide death cases are presented in which suicide notes were written on the bodies of the victims. The first case, a 32-year-old man, was a university graduate and had been unemployed for years; he committed suicide in his house by hanging. On the external examination, it was seen that there were some words on the body written with a pen; specifically "DONKEY" was written on the forehead; coursing up-and-down along the chest, "HODJA" was on the right, "DO NOT" was on the sternal region, and "WASH" was on the left; and undecipherable handwritings were on both zygomatic regions. The second case, a 39-year-old woman, was a housewife who was being physically abused by her husband and committed suicide by ingesting an insecticide. It was observed that on the left leg, a note was written with a pen saying that she could not stand being beaten by her husband on account of the inheritance dispute between him and her elder brother; there was purple ecchymoses in the periphery of the right eye and in the right gluteal area. Since we have not found any reports of suicide notes written on the body in the literature, we present and discuss our cases herein.

    We discuss when static Killing vector fields are standard, that is, leading to a global orthogonal splitting of the spacetime. We prove that such an orthogonal splitting is unique whenever the natural space is compact. This is carried out by proving that many notable spacelike submanifolds must be contained in an orthogonal slice. Possible obstructions to the global splitting are also considered.

    The notes which play the most important and second most important roles in expressing a raga are called Vadi and Samvadi swars respectively in (North) Indian Classical music. Like Bageshree, Bhairavi, Shankara, Hamir and Kalingra, Rageshree is another controversial raga so far as the choice of Vadi-Samvadi selection is concerned where there are two different opinions. In the present work, a two minute vocal recording of raga Rageshree is subjected to a careful statistical analysis. Our analysis is broken into three phases: first half, middle half and last half. Under a multinomial model set up holding appreciably in the first two phases, only one opinion is found acceptable. In the last phase the distribution seems to be quasi multinomial, characterized by an unstable nature of relative occurrence of pitch of all the notes and although the note whose relative occurrence of pitch suddenly shoots is the Vadi swar selected from our analysis of the first two phases, we take it as an outlier demanding a separate t...

    What if you had access to all your students' notes, their questions, their answers to questions you posed in class and when they were confused in class. What could you do with that information to help guide your students. With the advent of in-class tools like LectureTools it is now possible to have such access to student data. This paper describes on-going research at the University of Michigan to explore how best to mine student notes and questions to provide adaptive learning opportunities to students. Student notes are parsed in real-time searching for keywords from the geosciences. These words and phrases are then linked to a variety of resources for those wishing further clarification. This presentation will demonstrate the tools that have been generated for students and report on the students' assessment of the value of such information. The presentation will use LectureTools to demonstrate the crowdsourcing. Attendees are encouraged to bring a mobile device to the session.

    The potential role of currency in the spread of pathogenic microflora has been evaluated in many countries. In this study Polish paper notes and the coins in general circulation were assayed for the presence of cultivable bacteria and fungi. Bacterial isolates identification was based on cultural and biochemical characters and by comparison of the 16S rRNA gene sequence. Fungal isolates were recognized with biochemical and morphological criteria. Coagulase-negative staphylococci, (43.6% of the total bacterial count) including Staphylococcus saprophyticus, S. epidermidis, and S. hominis, and Enteroccus spp. (30.8% of the total bacterial count), i.e. E.faecalis, E.faecium and E. durans, were the most numerous bacterial contamination. Penicillium spp., and Aspergillus spp. were the most frequently detected moulds whereas Candida spp. was the most frequent yeast isolated from currency. A visible dependence between the banknote denomination, the physical condition of paper currency, and the number of bacteria and fungi was found. The overall count of bacteria isolated from currency was thousand-fold higher than that of fungal isolates. The total amount of bacteria and fungi recovered from the coins was approximately 2.7-fold lower than that isolated from the notes. In summary, the Polish currency notes were found to be contaminated mainly with commensal bacteria and fungi while the opportunistic pathogenic microorganisms Escherichia coli, Pseudomonas stutzeri and C. albicans were detected at a low frequency.

    This collection of course notes from a number theory summer school focus on aspects of Diophantine Analysis, addressed to Master and doctoral students as well as everyone who wants to learn the subject. The topics range from Baker’s method of bounding linear forms in logarithms (authored by Sanda Bujačić and Alan Filipin), metric diophantine approximation discussing in particular the yet unsolved Littlewood conjecture (by Simon Kristensen), Minkowski’s geometry of numbers and modern variations by Bombieri and Schmidt (Tapani Matala-aho), and a historical account of related number theory(ists) at the turn of the 19th Century (Nicola M.R. Oswald). Each of these notes serves as an essentially self-contained introduction to the topic. The reader gets a thorough impression of Diophantine Analysis by its central results, relevant applications and open problems. The notes are complemented with many references and an extensive register which makes it easy to navigate through the book.

    In this note we discuss the approximation of integrals that depend on a parameter. The basic tool is simple, namely, integration by parts. Of course, the power of the tool is evidenced in applications. The applications are many; they include Laplace integrals, generalized Laplace integrals, Fourier integrals, and Stokes' method of stationary phase for generalized Fourier integrals. These results illustrate beautifully Hardy's concept of applications of mathematics, that is, certain regions of mathematical theory in which the notation and the ideas of the (method of integration by parts] may be used systematically with a great gain in clearness and simplicity''. The notation differs slightly from Working Note No. 1, for reasons that are mainly historical. The asymptotic analysis of integrals originated in complex analysis, where the (real or complex) parameter, usually denoted by x, is usually introduced in such a way that the interesting behavior of the integrals occurs when x [yields] [infinity] in some sector of the complex plane. As there is nothing sacred about notation, and historical precedent is as good a guide as any, we follow convention and denote the parameter by x, focusing on the behavior of integrals as x [yields] [infinity] along the real axis or, if x is complex, in some sector of the complex plane. The connection with the notation of Working Note No. 1 is readily established by identifying the small parameter [epsilon] with [vert bar]x[vert bar][sup [minus]1].

    Full Text Available Gallstone ileus is a rare mechanical bowel obstruction, and previously reported cases have been treated laparoscopically with good results. Although transvaginal hybrid NOTES without a minilaparotomy has been reported to decrease the incidence of surgical wound complications, to our knowledge, this procedure has not been used previously to treat gallstone ileus. We present a case of a 63-year-old woman who underwent transvaginal hybrid NOTES procedure for treatment of gallstone ileus. This case was admitted to our hospital following acute-onset abdominal pain and vomiting. We diagnosed gallstone ileus with cholecystoduodenal fistula by computed tomography and performed totally laparoscopic surgery using only three 5 mm abdominal ports with transvaginal specimen extraction and enterectomy. The patient’s postoperative course was uneventful, and laparoscopic cholecystectomy and fistula repair were performed 8 months after the initial surgery. The patient experienced additional pain relief and good cosmetic outcomes. In conclusion, using transvaginal hybrid NOTES may become a future option to minimize the invasiveness of other laparoscopic procedures.

We diagnosed gallstone ileus with cholecystoduodenal fistula by computed tomography and performed totally laparoscopic surgery using only three 5 mm abdominal ports with transvaginal specimen extraction and enterectomy. The patient's postoperative course was uneventful, and laparoscopic cholecystectomy and fistula repair were performed 8 months after the initial surgery. The patient experienced additional pain relief and good cosmetic outcomes. In conclusion, using transvaginal hybrid NOTES may become a future option to minimize the invasiveness of other laparoscopic procedures. PMID:27429831

  12. A note on connected formula for form factors

    He, Song

    2016-01-01

    In this note we study the connected prescription, originally derived from Witten's twistor string theory, for tree-level form factors in ${\\cal N}=4$ super-Yang-Mills theory. The construction is based on the recently proposed four-dimensional scattering equations with $n$ massless on-shell states and one off-shell state, which we expect to work for form factors of general operators. To illustrate the universality of the prescription, we propose compact formulas for super form factors with chiral stress-tensor multiplet operator, and bosonic ones with scalar operators ${\\rm Tr}(\\phi^m)$ for arbitrary $m$.

  13. Note on recursion relations for the Q -cut representation

    2017-01-01

    In this note, we study the Q -cut representation by combining it with BCFW deformation. As a consequence, the one-loop integrand is expressed in terms of a recursion relation, i.e., n-point one-loop integrand is constructed using tree-level amplitudes and m-point one-loop integrands with m ≤ n - 1. By giving explicit examples, we show that the integrand from the recursion relation is equivalent to that from Feynman diagrams or the original Q -cut construction, up to scale free terms.

    Gharibi, Wajeb

    2011-01-01

    Separable nonlinear least squares (SNLS)problem is a special class of nonlinear least squares (NLS)problems, whose objective function is a mixture of linear and nonlinear functions. It has many applications in many different areas, especially in Operations Research and Computer Sciences. They are difficult to solve with the infinite-norm metric. In this paper, we give a short note on the separable nonlinear least squares problem, unseparated scheme for NLS, and propose an algorithm for solving mixed linear-nonlinear minimization problem, method of which results in solving a series of least squares separable problems.

    2010-01-01

    Recently a reformulation of the MHV diagram method in N=4 supersymmetric Yang-Mills theory in momentum twistor space was presented and was shown to be equivalent to the perturbative expansion of the expectation value of a supersymmetric Wilson loop in momentum twistor space. In this note we present related explicit Feynman rules in dual momentum space, which should have the interpretation of Wilson loop diagrams in dual momentum space. We show that these novel rules are completely equivalent to ordinary spacetime MHV rules and can be naturally viewed as their graph dual representation.

    2007-01-01

    In this note, we develop stock option price approximations for a model which takes both the risk o default and the stochastic volatility into account. We also let the intensity of defaults be influenced by the volatility. We show that it might be possible to infer the risk neutral default intensity from the stock option prices. Our option price approximation has a rich implied volatility surface structure and fits the data implied volatility well. Our calibration exercise shows that an effective hazard rate from bonds issued by a company can be used to explain the implied volatility skew of the implied volatility of the option prices issued by the same company.

    2014-12-01

    Full Text Available This study revolves around notes and critiques of Bikol lexicography. Based on a selection of six dictionaries, the structure and diachronic development of Bikol lexicography were analyzed. Half of the selected dictionaries were authored in full or part by Malcolm Mintz, a renowned Bikol expert. These enabled a linear analysis of changes in lexicography that have occurred within the span of four decades. The dictionaries studied include the earliest and most influential Bikol dictionary of Lisboa (1865. The study presents a preliminary description of lexicographic work done in Bikol and traces the shift in the paradigm of dictionary making from the Spanish era to the present.

    Barker, Blake; Johnson, Mathew A.; Noble, Pascal; Rodrigues, Luis Miguel; Zumbrun, Kevin

    2017-02-01

    In this note, we announce a complete classification of the stability of periodic roll-wave solutions of the viscous shallow water equations, from their onset at Froude number F ≈ 2 up to the infinite Froude limit. For intermediate Froude numbers, we obtain numerically a particularly simple power-law relation between F and the boundaries of the region of stable periods, which appears potentially useful in hydraulic engineering applications. In the asymptotic regime F → 2 (onset), we provide an analytic expression of the stability boundaries, whereas in the limit F → ∞, we show that roll waves are always unstable.

    This brief note has the didactical purpose of discussing the meaning of the uncertainty principle involving energy and time in quantum mechanics by means of a review of the seminal works on this subject. The importance of this topic is, indeed, frequently neglected in several textbooks on quantum mechanics. Then, these pages are addressed to students attenting to an undergraduate course on quantum theory; and the original aim is that of presenting a list of references of the points that take part in the principal discussions on the subject. Special attention is devoted to the discussion of the fallacies, which are certainly persistent in the didactical literature.

  9. The pen is mightier than the keyboard: advantages of longhand over laptop note taking.

    Science.gov (United States)

    Mueller, Pam A; Oppenheimer, Daniel M

    2014-06-01

    Taking notes on laptops rather than in longhand is increasingly common. Many researchers have suggested that laptop note taking is less effective than longhand note taking for learning. Prior studies have primarily focused on students' capacity for multitasking and distraction when using laptops. The present research suggests that even when laptops are used solely to take notes, they may still be impairing learning because their use results in shallower processing. In three studies, we found that students who took notes on laptops performed worse on conceptual questions than students who took notes longhand. We show that whereas taking more notes can be beneficial, laptop note takers' tendency to transcribe lectures verbatim rather than processing information and reframing it in their own words is detrimental to learning. © The Author(s) 2014.

    Directory of Open Access Journals (Sweden)

    Günter Mey

    2004-01-01

    Full Text Available Editorial Notes provide a view "behind the scenes" of FQS Reviews, reporting and describing the editorial process. The first topic in this Editorial Note focuses on changes in the way reviewers are found. As FQS Reviews began we preferred finding reviewers by posting on different listservs to inform others about review copies of books and other media. In the next phase of FQS Reviews—aside from postings—we attempted to establish a core of authors who would exclusively write reviews. The second topic describes an analyses of 131 archived files (first drafts of reviews published in FQS and the analyses of the e-mail contacts between the reviewers and the editorial team which accompany the peer review process. One result of our analyses is that the quality of a review is independent from way the reviewer was recruited (postings on listservs or established core reviewer; no significant differences can be seen between the two groups (reviewers found via listservs or established reviewers. More, important, however, is the intensive "communication work" between editors and reviewers—a necessary communication to guarantee standardization and maintenance of quality. This is critical as our focus is on the review as a "unique contribution" within the research community. To give an insight into the intensive communication work an anonymous case study of a "failed" review is included. URN: urn:nbn:de:0114-fqs040115

  13. A hybrid system for emotion extraction from suicide notes.

    Science.gov (United States)

    Nikfarjam, Azadeh; Emadzadeh, Ehsan; Gonzalez, Graciela

    2012-01-01

    The reasons that drive someone to commit suicide are complex and their study has attracted the attention of scientists in different domains. Analyzing this phenomenon could significantly improve the preventive efforts. In this paper we present a method for sentiment analysis of suicide notes submitted to the i2b2/VA/Cincinnati Shared Task 2011. In this task the sentences of 900 suicide notes were labeled with the possible emotions that they reflect. In order to label the sentence with emotions, we propose a hybrid approach which utilizes both rule based and machine learning techniques. To solve the multi class problem a rule-based engine and an SVM model is used for each category. A set of syntactic and semantic features are selected for each sentence to build the rules and train the classifier. The rules are generated manually based on a set of lexical and emotional clues. We propose a new approach to extract the sentence's clauses and constitutive grammatical elements and to use them in syntactic and semantic feature generation. The method utilizes a novel method to measure the polarity of the sentence based on the extracted grammatical elements, reaching precision of 41.79 with recall of 55.03 for an f-measure of 47.50. The overall mean f-measure of all submissions was 48.75% with a standard deviation of 7%.

  14. Dementia deaths in hospice: a retrospective case note audit.

    Science.gov (United States)

    Vries, Kay de; Nowell, Allyson

    2011-12-01

    Dementia is now recognized as a progressive terminal illness and it is established that people with dementia have significant palliative care needs as they approach the end of life. However, population prevalence studies suggest that very few people with dementia access hospice services in the UK. The literature further suggests that hospice staff may be inadequately prepared to care for people with dementia. A retrospective internal case note audit covering a 3-month period of referrals was undertaken in one hospice in the south of England as part of work to establish staff education requirements arising from patient make-up. Only patients over the age of 65 were included. Of the 288 case notes audited, 9% of the patients had either been diagnosed with dementia or suffered with dementia as a comorbidity. The results of the audit suggest that the number of people with dementia referred to hospice services may have increased in the last decade. This is in keeping with expectations and future predictions resulting from increased disease surveillance and an increasingly ageing population.

  15. Notes on a methodological discussion: autobiography, critique and time

    Directory of Open Access Journals (Sweden)

    Gunvor Løkken

    2010-06-01

    Full Text Available After having tried for some time to overview the contemporary field of qualitative research to give a lecture for a professorship in that area, my idea at the outset of writing this article was to address whether changes in qualitative research should be viewed as recurrent revolutions as highlighted by Denzin and Lincoln (2000; 2005, or as a field of continuing key themes and long-standing tensions, as conceptualized by Atkinson, Coffey and Delamont (2003. However, during my writing, after one detour into the May 2009 issue of Current Sociology and a second detour into the July 2009 issue of Qualitative Research, my attention focused on to how critical debate and review are displayed in different methodological positions of qualitative research. In my reading, the discussion in Current Sociology between main stream and postmodern methodological positioning revealed an utterly one-way feminist critique; this was also the case in one of three book reviews of The Handbook of Qualitative Research (Denzin and Lincoln, 2005 in the referred issue of Qualitative Research. My puzzle over this critical stance, and my third detour, into Yvonne Lincoln’s discussion of twenty-five years of qualitative and new paradigm research in the January 2010 Issue of Qualitative Inquiry, helped evolve the following notes on a methodological discussion. The notes are partly structured by a temporal narrative over personally lived qualitative research, and partly by an epistemological narrative of a methodological discussion, interwoven with the passing of time when writing.

    Jennifer Giroux

    2013-12-01

    Full Text Available The January 2013 attack on the In Amenas natural gas facility drew international attention. However this attack is part of a portrait of energy infrastructure targeting by non-state actors that spans the globe. Data drawn from the Energy Infrastructure Attack Database (EIAD shows that in the last decade there were, on average, nearly 400 annual attacks carried out by armed non-state actors on energy infrastructure worldwide, a figure that was well under 200 prior to 1999. This data reveals a global picture whereby violent non-state actors target energy infrastructures to air grievances, communicate to governments, impact state economic interests, or capture revenue in the form of hijacking, kidnapping ransoms, theft. And, for politically motivated groups, such as those engaged in insurgencies, attacking industry assets garners media coverage serving as a facilitator for international attention. This research note will introduce EIAD and position its utility within various research areas where the targeting of energy infrastructure, or more broadly energy infrastructure vulnerability, has been addressed, either directly or indirectly. We also provide a snapshot of the initial analysis of the data between 1980-2011, noting specific temporal and spatial trends, and then conclude with a brief discussion on the contribution of EIAD, highlighting future research trajectories. 

  17. Why risk is not variance: an expository note.

    Science.gov (United States)

    Cox, Louis Anthony Tony

    2008-08-01

    Variance (or standard deviation) of return is widely used as a measure of risk in financial investment risk analysis applications, where mean-variance analysis is applied to calculate efficient frontiers and undominated portfolios. Why, then, do health, safety, and environmental (HS&E) and reliability engineering risk analysts insist on defining risk more flexibly, as being determined by probabilities and consequences, rather than simply by variances? This note suggests an answer by providing a simple proof that mean-variance decision making violates the principle that a rational decisionmaker should prefer higher to lower probabilities of receiving a fixed gain, all else being equal. Indeed, simply hypothesizing a continuous increasing indifference curve for mean-variance combinations at the origin is enough to imply that a decisionmaker must find unacceptable some prospects that offer a positive probability of gain and zero probability of loss. Unlike some previous analyses of limitations of variance as a risk metric, this expository note uses only simple mathematics and does not require the additional framework of von Neumann Morgenstern utility theory.

    Stalmans, Sofie; Willems, Maxime; Adriaens, Els; Remon, Jean-Paul; D'Hondt, Matthias; De Spiegeleer, Bart

    2014-10-01

    Flatworms possess adult pluripotent stem cells, which make them extraordinary experimental model organisms to assess in vivo the undesirable effects of substances on stem cells. Currently, quality practices, implying evaluation of the stability of the test compound under the proposed experimental conditions, are uncommon in this research field. Nevertheless, performing a stability study during the rational design of in vivo assay protocols will result in more reliable assay results. To illustrate the influence of the stability of the test substance on the final experimental outcome, we performed a short-term International Conference on Harmonization (ICH)-based stability study of cyclophosphamide in the culture medium, to which a marine flatworm model Macrostomum lignano is exposed. Using a validated U(H)PLC method, it was demonstrated that the cyclophosphamide concentration in the culture medium at 20°C is lowered to 80% of the initial concentration after 21days. The multiwell plates, flatworms and diatoms, as well as light exposure, did not influence significantly the cyclophosphamide concentration in the medium. The results of the stability study have practical implications on the experimental set-up of the carcinogenicity assay like the frequency of medium renewal. This case study demonstrates the benefits of applying appropriate quality guidelines already during fundamental research increasing the credibility of the results.

    The electronic health record (EHR) has been viewed with both praise and skepticism. Multiple editorials have expressed concerns that EHR implementation and "efficiency tools" such as copy forward and auto population have resulted in a decrement in note accuracy, relevance, and critical thinking. To evaluate the perceptions of internal medicine housestaff and attendings on inpatient progress note quality at 4 academic institutions after the implementation of an EHR. Cross-sectional survey. We developed surveys that assessed housestaff and attendings opinion of current progress note quality, the impact of the EHR on quality, and the purposes of a progress note. We received 99 completed surveys from interns (66%), 155 from residents (49%), and 153 from attendings (70%) across 4 institutions. The majority of housestaff responded that the quality of notes was "unchanged" or "better" following the implementation of an EHR, whereas attendings believed note quality was "unchanged" or "worse." Attendings' perceptions of housestaff notes were significantly lower than housestaff perceptions of their own notes across all domains. With regard to the effect of copy forward and autopopulation, the majority of housestaff viewed these to be "neutral" or "somewhat positive," whereas attendings viewed these as "neutral" or "somewhat negative." Housestaff and attendings had nearly perfect agreement regarding the purpose of the progress note. Attendings and housestaff disagree on the current quality of progress notes and the impact of an EHR on note quality, but agree on the purpose of a progress note. © 2015 Society of Hospital Medicine.

    Science.gov (United States)

    Kiewra, Kenneth A.; And Others

    1995-01-01

    Two experiments, involving 195 undergraduates, investigated how different note-taking formats influenced student note taking. Results reconfirmed that a flexible outline framework in which the order of subtopics corresponds to the order of lecture presentation produces more note taking than a collapsed matrix framework presenting fewer subtopics.…

    Students with learning disabilities lack effective note-taking skills for a variety of reasons. Despite the important role that notes play in helping students to understand lecture content information and serving as documents for later review, many students with learning disabilities are simply not effective note-takers. Many of these students…

    Natural orifice translumenal endoscopic surgery (NOTES) procedures are rapidly being developed in diverse surgical fields. We are developing a Virtual Translumenal Endoscopic Surgery Trainer (VTEST™) built on a modularized platform that facilitates rapid development of virtual reality (VR) NOTES simulators. Both the hardware interface and software components consist of independent reusable and customizable modules. The developed modules are integrated to build a VR-NOTES simulator for training in the hybrid transvaginal NOTES cholecystectomy. The simulator was demonstrated and evaluated by expert NOTES surgeons at the 2015 Natural Orifice Surgery Consortium for Assessment and Research (NOSCAR) summit.

  15. Technical design note: differential infrared thermography of methane jets

    Science.gov (United States)

    Golzke, Hendrik; Leick, Philippe; Dreizler, Andreas

    2016-10-01

    In this note a novel approach for temperature measurements of methane jets is presented. Differential infrared thermography (DIT) is a contactless, tracer-free temperature determination method for semi-transparent objects, based on an infrared camera. DIT does not rely on a specific a priori value for the emissivity, but typically assumes constant emissivity within the relevant wavelength band. This is reasonable for complex hydrocarbons (i.e. as in liquid fuel sprays) but no longer justified for the discrete absorption spectrum of simple molecules such as methane. An alternative approximation is suggested and discussed, and the feasibility of DIT for the study of supercritical methane jets in a pressure chamber at conditions relevant for internal combustion engines is demonstrated. As DIT also determines the gas emissivity, a combined two-dimensional temperature and projected density visualisation becomes possible and is shown to highlight supersonic structurues such as Mach disks.

  16. A note on risk adjustment and fair compensation.

    Science.gov (United States)

    Shmueli, A

    2000-09-01

    This note comments on the application of results from the theory of fair compensation to risk adjustment. It argues that the main flaw of such application lies in the consideration of health plans merely as administrative social agents, through which money flows from a central fund to providers of medical care, ignoring their economic behaviour. However, it is that behaviour which raises the issue of risk selection to begin with. With linear health expenditure function, the fair compensation axiomatic solution is shown to be equivalent to the solution of a simple optimal regulation problem. That equivalence permits the analysis of several further issues related to risk adjustment and to the application of the theory of fair compensation to it.

    2004-01-01

    In this note we show that for a given controllable pair ( A, B ) and any λ> 0, a gain matrix K can be chosen so that the transition matrix e(A+BK)t of the system x = (A + BK)x decays at the exponential rate e-λt and the overshoot of the transition matrix can be bounded by MλL for some constants M and L that are independent ofλ. As a consequence, for any h >0, a gain matrix K can be chosen so that the magnitude of the transition matrix e(A+BK)t can be reduced by -1/2- (orby anygivenportion) over [0, h ] . An interesting applicafon of the result is in the stabilization of switched linear systems with any given switching rate ( see [ 1 ] ).

  18. Notes on dumping gold beam in the AGS

    Energy Technology Data Exchange (ETDEWEB)

    Gardner, C.J.; Ahrens, L.; Thieberger, P.

    2010-08-01

    Localized losses of gold beam in the AGS during RHIC Run 8 produced vacuum leaks which required the replacement of several vacuum chambers. A review of what happened and why was given by Leif Ahrens at the Run 8 Retreat. The following notes trace the subsequent development of clean dumping of gold beam on the beam dump in the J10 straight. The novel idea of stripping Au77+ ions in order to put them directly into the upstream face of the dump was introduced by Leif Ahrens and developed by all three of us. George Mahler made the actual stripping device and Dave Gassner developed its control. Leif Ahrens successfully commissioned the device with gold beam during Run 10. The reader may find it helpful to first view the figures herein and then refer to the text for details.

  19. Note: Continuous synthesis of uniform vertical graphene on cylindrical surfaces.

    Science.gov (United States)

    Bo, Zheng; Cui, Shumao; Yu, Kehan; Lu, Ganhua; Mao, Shun; Chen, Junhong

    2011-08-01

    This note describes a new reactor design for continuous synthesis of vertically oriented graphene (VG) sheets on cylindrical wire substrates using an atmospheric plasma-enhanced chemical vapor deposition (PECVD) system. Through combining a U-shaped reactor design with "dynamic mode" synthesis featuring simultaneous rotational and axial movements of the metallic wire substrate, the new setup can enable continuous synthesis of VG sheets on the wire surface with remarkable uniformity in both circumferential and axial directions. In contrast, synthesis of VG at "static mode" with a fixed substrate can only lead to non-uniform growth of VG sheets on the wire surface. Potential applications of the resulting uniform-VG-coated metallic wire could include field emitters, field-ionization-based neutral atom detectors, and indoor corona discharges.

  20. Note: computational estimation of sparkgap inductance in nitrogen medium.

    Science.gov (United States)

    Mitra, S; Singh, Sandeep; Kumar, Ranjeet; Sharma, Archana; Mittal, K C

    2014-04-01

    In this Note, attempt has been made to analytically derive the inductance of a sparkgap arc channel using fundamental circuit theory, heat transfer theory, and gas plasma equations. Simulation of a picosecond phenomenon of arc channel formation is attempted using coupled codes. Arc channel is assumed to be cylindrical and modeled as finite number of small coaxial cylinders filled with gas plasma. Conductivity of each gas plasma cylinder is found by its temperature. Current distribution in the cylinders is calculated using circuit theory and change in the current distribution with time is simulated. Over all inductance of the arc channel is computed for the current density distribution. Simulation is done for fast sub-nanosecond rising pulse. Experiments are conducted to measure the arc channel inductance and validate the same with the value found using computation.

  2. Note on Identities Inspired by New Soft Theorems

    CERN Document Server

    Rao, Junjie

    2016-01-01

    The new soft theorems, for both gravity and gauge amplitudes, have inspired a number of works, including the discovery of new identities related to amplitudes. In this note, we present the proof and discussion for two sets of identities. The first set includes an identity involving the half-soft function which had been used in the soft theorem for one-loop rational gravity amplitudes, and another simpler identity as its byproduct. The second set includes two identities involving the KLT momentum kernel, as the consistency conditions of the KLT relation plus soft theorems for both gravity and gauge amplitudes. We use the CHY formulation to prove the first identity, and transform the second one into a convenient form for future discussion.

  3. The Masoretic Notes in Three Commentaries Attributed to Rashi

    2011-12-01

    Full Text Available Using the Mikra ̓ot Gedolot ‘Haketer’ version of Rashi’s commentary on three Biblical passages (Deuteronomy 33:23, Isaiah 14:11 and Ezekiel 17:9 the author reviews the textual version of the commentaries’ transmission from medieval manuscripts to print editions. Addressing their meaning and adducing the masoretic notes that the Meyuḥas may have used in making additions, the author demonstrates that these later additions have generated erroneous attributions to Rashi’s original commentaries. In the first two cases, the commentator employs the Masorah note as an interpretive tool. Firstly, he cites the Masorah Magna to support his claim that this unusual form of ירְָשָֽׁה (Deut 33:23 is indeed in the imperative. Secondly, the commentator adduces from a masoretic note that the word נבְָלֶ֑יך (Isa 14:11, which occurs twice in the Bible in this form has two meanings. In the third case, the Masorah note had no interpretive agenda; it merely pointed out that all the letters of the Hebrew alphabet appear in Ezekiel 17:9.

    Partiendo de la versión del comentario de Raší a tres pasajes bíblicos (De 33:23, Is 14:11 y Ez 17:9 contenida en las Mikra ̓ot Gedolot ‘Haketer’, la autora revisa la transmisión del texto de dichos comentarios desde los manuscritos medievales a las ediciones impresas. Mediante el análisis de su significado y aduciendo las notas masoréticas contenidas en las adiciones, y que había sido atribuido (Meyuḥas a Raší, la autora demuestra que dicha atribución puede ser errónea y no corresponde a los comentarios originales de este autor. En los dos primeros pasajes estudiados, se muestra cómo el comentarista había empleado la nota de la masora como instrumento de interpretación. En primer lugar, cita la Masora Magna para apoyar su afirmación de que la forma inusual de ירְָשָֽׁה (De 33:23 estuviera en imperativo. En segundo lugar, partiendo de una

  4. A Note On Einstein, Bergmann, and the Fifth Dimension

    CERN Document Server

    Witten, Edward

    2014-01-01

    This note is devoted to a detail concerning the work of Albert Einstein and Peter Bergmann on unified theories of electromagnetism and gravitation in five dimensions. In their paper of 1938, Einstein and Bergmann were among the first to introduce the modern viewpoint in which a four-dimensional theory that coincides with Einstein-Maxwell theory at long distances is derived from a five-dimensional theory with complete symmetry among all five dimensions. But then they drew back, modifying the theory in a way that spoiled the five-dimensional symmetry and looks contrived to modern readers. Why? According to correspondence of Peter Bergmann with the author, the reason was that the more symmetric version of the theory predicts the existence of a new long range field (a massless scalar field). In 1938, Einstein and Bergmann did not wish to make this prediction. (Based on a lecture at the Einstein Centennial Celebration at the Library of Alexandria, June, 2005.

    2007-01-01

    Let {Ln(A,λ)(x)}n≥0 be the sequence of monic Laguerre matrix polynomials defined on [0, ∞) by Ln(A,λ)(x)=n!/(-λ)n∑nk=0(-λ)κ/k!(n-1)! (A+I)n[(A+I)k]-1 xk,where A ∈ Cr×r. It is known that {Ln(A,λ)(x)}n≥0 is orthogonal with respect to a matrix moment functional when A satisfies the spectral condition that Re(z) > - 1 for every z ∈σ(A).In this note we show that forA such that σ(A) does not contain negative integers, the Laguerre matrix polynomials Ln(A,λ) (x) are orthogonal with respect to a non-diagonal SobolevLaguerre matrix moment functional, which extends two cases: the above matrix case and the known scalar case.

    Generalized lock-in amplifiers use digital cavities with Q-factors as high as 5 × 108 to measure signals with very high precision. In this Note, we show that generalized lock-in amplifiers can be used to analyze microwave (giga-hertz) signals with a precision of few tens of hertz. We propose that the physical changes in the medium of propagation can be measured precisely by the ultra-high precision measurement of the signal. We provide evidence to our proposition by verifying the Newton's law of cooling by measuring the effect of change in temperature on the phase and amplitude of the signals propagating through two calibrated cables. The technique could be used to precisely measure different physical properties of the propagation medium, for example, the change in length, resistance, etc. Real time implementation of the technique can open up new methodologies of in situ virtual metrology in material design.

  7. A Note on Realistic Dividends in Actuarial Surplus Models

    Directory of Open Access Journals (Sweden)

    Benjamin Avanzi

    2016-10-01

    Full Text Available Because of the profitable nature of risk businesses in the long term, de Finetti suggested that surplus models should allow for cash leakages, as otherwise the surplus would unrealistically grow (on average to infinity. These leakages were interpreted as ‘dividends’. Subsequent literature on actuarial surplus models with dividend distribution has mainly focussed on dividend strategies that either maximise the expected present value of dividends until ruin or lead to a probability of ruin that is less than one (see Albrecher and Thonhauser, Avanzi for reviews. An increasing number of papers are directly interested in modelling dividend policies that are consistent with actual practice in financial markets. In this short note, we review the corporate finance literature with the specific aim of fleshing out properties that dividend strategies should ideally satisfy, if one wants to model behaviour that is consistent with practice.

  8. Mentoring: Some cautionary notes for the nursing profession.

    Science.gov (United States)

    Green, Janet; Jackson, Debra

    2014-01-01

    Abstract Mentoring has been embraced in nursing as a way of socialising new nurses into the profession, growing and developing nursing talent, and more recently as a way to retain experienced nurses with the current nursing shortage. Much of the extant literature focusses on the benefits of mentoring, differences between formal and informal mentoring, the elements of a successful mentoring relationship, and the characteristics of 'good' mentors and protégées. Until recently the research on mentoring has almost exclusively focussed on the positive aspects of mentoring for the protégées, organisations and to a lesser extent, mentors. While viewed by many as a beneficial and enriching developmental experience, it is equally important to recognise that there can be a darker side to the mentoring experience for the mentor and protégée. This paper will explore the negative aspects associated with mentoring and mentoring relationships and provide some cautionary notes for nursing.

  9. Use of an anecdotal client feedback note in family therapy.

    Haber, Russell; Carlson, Ryan G; Braga, Cristina

    2014-06-01

    To attain information about divergent agendas in family therapy, as well as incorporate client feedback, we present the Client Feedback Note (CFN). The CFN elicits information about each family member's feelings, learning, dislikes, and wishes for each session. Anecdotal feedback after each session may help the therapist have better insight into the clients' perceptions and experience of the therapy and the therapist. Sensitivity to information generated by the CFN can help both therapist and client work to coconstruct a therapeutic process that is relevant to the diverse needs of the client system. This manuscript will (a) discuss literature supporting the use of client feedback in therapy; (b) present the CFN and rationale for its development; (c) discuss our experiences utilizing the CFN along with case examples that illustrate its use; and (d) identify practical applications, limitations, and potential research with using the CFN in systemic therapy. © 2014 FPI, Inc.

  10. A note on generalized hydrodynamics: inhomogeneous fields and other concepts

    CERN Document Server

    Doyon, Benjamin

    2016-01-01

    Generalized hydrodynamics (GHD) was proposed recently as a formulation of hydrodynamics for integrable systems, taking into account infinitely-many conservation laws. In this note we further develop the theory in various directions. By extending GHD to all commuting flows of the integrable model, we provide a full description of how to take into account weakly varying force fields, temperature fields and other inhomogeneous external fields within GHD. We expect this can be used, for instance, to characterize the non-equilibrium dynamics of one-dimensional Bose gases in trap potentials. We also show that the GGE equations of state, and thus GHD, emerge uniformly in free particle models under the condition that the space-time variation scale of hydrodynamic observables grows unboundedly with time. We further show how the equations of state at the core of GHD follow from the continuity relation for entropy, and we show how to recover Euler-like equations and discuss possible viscosity terms.

  11. A Supervised Classification Algorithm for Note Onset Detection

    Directory of Open Access Journals (Sweden)

    Douglas Eck

    2007-01-01

    Full Text Available This paper presents a novel approach to detecting onsets in music audio files. We use a supervised learning algorithm to classify spectrogram frames extracted from digital audio as being onsets or nononsets. Frames classified as onsets are then treated with a simple peak-picking algorithm based on a moving average. We present two versions of this approach. The first version uses a single neural network classifier. The second version combines the predictions of several networks trained using different hyperparameters. We describe the details of the algorithm and summarize the performance of both variants on several datasets. We also examine our choice of hyperparameters by describing results of cross-validation experiments done on a custom dataset. We conclude that a supervised learning approach to note onset detection performs well and warrants further investigation.

  12. Some notes on ideology of waves in plasmas

    CERN Document Server

    Soshnikov, V N

    2002-01-01

    Our last three papers provide an occasion to make some brief notes on ideology of waves in plasmas and to rehabilitate Vlasov prescription to calculate relevant logarithmically divergent integrals in the principal value sense. In this approach asymptotical solutions of plasma oscillations are selected according to self-consistent boundary physical conditions. Landau damping is absent in this case by definition. Boundary electrical field together with conditions of absence of unphysical backward and kinematical waves define single-valued dependence of boundary distribution function on electron velocity \\vec{v} in the case of transversal waves and on the surface break of the normal electrical field in the case of longitudinal oscillations. We have proposed physically more justified modified iteration procedure of collisional damping calculation and demonstrated some results of damping decrements calculations in a low-collision electron-ion plasma. Dispersion smearing of both longitudinal and transversal high-fr...

  13. A Note on Encodings of Phylogenetic Networks of Bounded Level

    CERN Document Server

    Gambette, Philippe

    2009-01-01

    Driven by the need for better models that allow one to shed light into the question how life's diversity has evolved, phylogenetic networks have now joined phylogenetic trees in the center of phylogenetics research. Like phylogenetic trees, such networks canonically induce collections of phylogenetic trees, clusters, and triplets, respectively. Thus it is not surprising that many network approaches aim to reconstruct a phylogenetic network from such collections. Related to the well-studied perfect phylogeny problem, the following question is of fundamental importance in this context: When does one of the above collections encode (i.e. uniquely describe) the network that induces it? In this note, we present a complete answer to this question for the special case of a level-1 (phylogenetic) network by characterizing those level-1 networks for which an encoding in terms of one (or equivalently all) of the above collections exists. Given that this type of network forms the first layer of the rich hierarchy of lev...

  14. Note On The Extended Non Commutativity of Coordinates

    CERN Document Server

    Boulahoual, A

    2001-01-01

    We present in this short note an idea about a possible extension of the standard noncommutative algebra to the formal differential operators framework. In this sense, we develop an analysis and derive an extended noncommutative algebra given by $[x_{a}, x_{b}]_{\\star} = i(\\theta + \\chi)_{ab}$ where $\\theta_{ab}$ is the standard noncommutative parameter and $\\chi_{ab}(x)\\equiv \\chi^{\\mu}_{ab}(x)\\partial_{\\mu} ={1/2}(x_a \\theta^{\\mu}_{b} - x_b \\theta^{\\mu}_{a})\\partial_\\mu$ is an antisymmetric non-constant vector-field shown to play the role of the extended deformation parameter. This idea was motivated by the importance of noncommutative geometry framework in the current subject of D-brane and matrix theory physics.

  15. Note on non-Gaussianities in two-field inflation

    Science.gov (United States)

    Wang, Tower

    2010-12-01

    Two-field slow-roll inflation is the most conservative modification of a single-field model. The main motivations to study it are its entropic mode and non-Gaussianity. Several years ago, for a two-field model with additive separable potentials, Vernizzi and Wands invented an analytic method to estimate its non-Gaussianities. Later on, Choi et al. applied this method to the model with multiplicative separable potentials. In this note, we design a larger class of models whose non-Gaussianity can be estimated by the same method. Under some simplistic assumptions, roughly these models are unlikely able to generate a large non-Gaussianity. We look over some specific models of this class by scanning the full parameter space, but still no large non-Gaussianity appears in the slow-roll region. These models and scanning techniques would be useful for a future model hunt if observational evidence shows up for two-field inflation.

    2012-01-01

    Full Text Available As elsewhere in Finland, different types of yoga practices are popular in the city of Åbo/Turku. But how do practitioners view their own relationship to their practice, and further, what do they feel that they as individuals gain from it? Through in-depth interviews with yoga teachers in the city of Turku, the author examines ways in which individuals, in what could be called a post-secular society, construct a meaningful sense of self and of individual agency. The observations offered in this article represent preliminary notes for a larger work on yoga in Turku, conducted at the ‘Post-Secular Culture and a Changing Religious Landscape’ research project at Åbo Akademi University, devoted to qualitative and ethnographic investigations of the changing religious landscape in Finland.

  17. Haptic Feedback in Natural Orifice Transluminal Endoscopic Surgery (NOTES)

    CERN Document Server

    Do, Thanh Nho

    2016-01-01

    Flexible tendon sheath mechanism is commonly used in NOTES systems because it offers high flexibility, light weight, and easy transmission. Due to the size constraints and sterilization problems, traditional sensors like force/torque sensor are extremely difficult to place at the tool tips of surgical arms. In addition, nonlinear dynamic friction and backlash cause challenges to provide haptic feedback to the surgeons when the robotic arms are inside the patient's body. Hence, it is extremely difficult to provide the force information to haptic devices and subsequently to the surgeons. To deal with these problems, in this paper we propose a new approach of friction model in the tendon-sheath mechanism to provide the force at distal end of endoscopic system. In comparison with current approaches in the literature, the proposed model is able to provide force information at zero velocity and it is smooth. In addition, the model is independent configuration and able to capture friction force with any complex shea...

  19. A Note on Lower Bounds for Colourful Simplicial Depth

    Directory of Open Access Journals (Sweden)

    Antoine Deza

    2013-01-01

    Full Text Available The colourful simplicial depth problem in dimension d is to find a configuration of (d+1 sets of (d+1 points such that the origin is contained in the convex hull of each set, or colour, but contained in a minimal number of colourful simplices generated by taking one point from each set. A construction attaining d2 + 1 simplices is known, and is conjectured to be minimal. This has been confirmed up to d = 3, however the best known lower bound for d ≥ 4 is ⌈(d+12 /2 ⌉. In this note, we use a branching strategy to improve the lower bound in dimension 4 from 13 to 14.

  3. Bion's Notes on memory and desire--its initial clinical reception in the United States: a note on archival material.

    While Bion's 1967 memory and desire paper reflected a crucial episode in his clinical thinking during his epistemological period, it was also central to his evolution as a Kleinian psychoanalyst who worked with seriously disturbed adult patients. The author explicates and contextualizes these claims with a new archival document, the Los Angeles Seminars delivered by Bion in April 1967, and the full-length version of Notes on memory and desire. Bion here instigated a radical departure from years of theory-laden work when he made his clinical work and ideas accessible to a new audience of American Freudian analysts. While this new group was keenly interested to hear about Bion's clinical technique with both borderline and psychotic patients, there were varied reactions to Bion's ideas on the technical implications of the analyst's abandonment of memory and desire. Both the Los Angeles Seminars and Notes elicited responses ranging from bewilderment, admiration to skepticism amongst his audience of listeners and readers. These materials also however allow for a more complete and systematic presentation of important ideas about analytic technique - and while his ideas in this domain have been long valued and known by many psychoanalysts, this contribution stresses the crucial aspect of the reception of his ideas about technique in a particular American context. American analysts gained a much more explicit idea of how Bion worked analytically, how he listened, formulated interpretations and factored in the analyst's listening receptivity in the here-and-now. The author concludes with a consideration of the importance of Bion's American reception in 1967.

  4. Note on governing equations for a discrete vortex method

    The characteristic of a coefficient matrix, which is derived from governing equations used in a discrete vortex method was investigated. The purpose of this note is to show the reduction of the rank of coefficient matrix when the vortices on the body are arranged symmetrically. When singular points are arranged symmetrically, the rank of the coefficient matrix derived from equation is reduced from m to (m-1). Then if Kelvin's theorem on circulation is introduced in equations, the rank becomes m. The uniqueness of the solution by using Cramer's theorem was obtained. The following three cases were taken into consideration:(1) even vortices, none on the symmetrial axis; (2) even vortices, two vortices on the symmetrical axis; (3) odd vortices, only one vortex on the symmetrical asix. The singularity of the coefficient matrix in the above-mentioned cases were proved. Firstly, the immutability of the characteristic of the coefficient matrix by the rotation of the coordinate system and the parallel transformation of that were proved. Then the x-axis was specified as symmetrical. (4 figs, 4 refs)

  5. A note on the discovery of a 2M⊙ pulsar

    It is conventionally thought that the state equation of dense matter softens and thus cannot result in high maximum mass if pulsars are quark stars and that a recently discovered 2M⊙ pulsar (PSR J1614-2230) may make pulsars unlikely to be quark stars.However, this standard point of view would be revisited and updated if quark clustering could occur in cold quark matter because of the strong coupling between quarks at realistic baryon densities in compact stars.It can be argued that the state equation of clustered quark matter stiffens to support compact stars with maximum mass Mmax > 2M⊙.In this brief note, it is demonstrated that large parameter space ranges are allowed for Mmax > 2M⊙ in a Lennard-Jones model of clustered quark matter and the newly measured highest mass of PSR J1614-2230 would be meaningful for constraining the number of quarks inside a single quark-cluster to be Nq (<) 103.

  6. A Note on the Kinetics of Diffusion-mediated Reactions

    2014-01-01

    The prevalent scheme of a diffusion-mediated bimolecular reaction $A+B\\rightarrow P$ is an adaptation of that proposed by Briggs and Haldane for enzyme action [{\\em Biochem J.\\/}, 19:338--339, 1925]. The purpose of this Note is to explain, {\\em by using an argument involving no mathematics\\/}, why the breakup of the encounter complex cannot be described, except in special circumstances, in terms of a first-order process $\\{AB\\}\\rightarrow A+B$. Briefly, such a description neglects the occurrence of re-encounters, which lie at the heart of Noyes's theory of diffusion-mediated reactions. The relation $k=\\alpha k_{\\mbox{\\scriptsize e}}$ becomes valid only when $\\alpha$ (the reaction probability per encounter) is very much smaller than unity (activation-controlled reactions), or when $\\beta$ (the re-encounter probability) is negligible (as happens in a gas-phase reaction). References to some works (by the author and his collaborators) which propound the correct approach for finding $k$ are also supplied.

  7. A note on continents and the Earth's Urey ratio

    Science.gov (United States)

    Lenardic, A.; Cooper, C. M.; Moresi, L.

    2011-09-01

    The Urey ratio (mantle heat production divided by heat loss) is a key constraint for thermal history models. Recent Urey ratio estimates are in the range of 0.21-0.49. It has been well noted in the literature that classic thermal history models predict a larger value. The extent of the discrepancy is considered significant enough to be deemed a paradox. The 'Urey ratio paradox' has motivated a number of studies and some considerable debates. Classic thermal history models, and the majority of those that have followed, do not explicitly consider the effects of continents. For consistency, the present day observations they seek to match should be adjusted to account for continents. We use mantle convection simulations with continents to argue that the adjusted ratio shifts to 0.33-0.76. Classic thermal history models predict a Urey ratio that, although at the high end, is within this range. This suggests that the 'paradox' has been exaggerated. It also points toward a first-order role for continents in the Earth's thermal evolution

  9. Notes on Relevant, Irrelevant, Marginal and Extremal Double Trace Perturbations

    Porrati, Massimo

    2016-01-01

    Double trace deformations, that is products of two local operators, define perturbations of conformal field theories that can be studied exactly in the large-N limit. Even when the double trace deformation is irrelevant in the infrared, it is believed to flow to an ultraviolet fixed point. In this note we define the Kallen-Lehmann representation of the two-point function of a local operator O in a theory perturbed by the square of such operator. We use such representation to discover potential pathologies at intermediate points in the flow that may prevent to reach the UV fixed point. We apply the method to an "extremal" deformation that naively would flow to a UV fixed point where the operator O would saturate the unitarity bound. We find that the UV fixed point is not conformal and that the deformed two-point function propagates unphysical modes and we interpret the result as showing that the flow to the UV fixed point does not exist. This resolves a potential puzzle in the holographic interpretation of the...

    2005-01-01

    I artiklen undersøges forholdet imellem filosofi og romankunst; til det formål slår forfatteren ned på tre tænkere - Camus, Proust og Sartre - som alle udmærker sig ved både at have en praktisk erfaring med, og en filosofisk-teoretisk tilgang til, romankunsten. Grundtanken i Sartres store romanværk...... (forklaring findes i artiklen) om Gustave Flaubert, L'Idiot de la famille, har forfatterens særlige bevågenhed, idet han i lyset af denne torso slutteligt sigter mod en kommentar til Sartres efterladte Notes sur 'Madame Bovary'. For Flaubert var gennembrudsromanen om 'livet i provinsen' udtryk for en...... 'derealisationsakt', mener Sartre. I sidste ende bliver spørgsmålet om romanens sandhed til et spørgsmål om imaginaritetens sandhed, som igen må ses i forhold til, at det sandsynlige og det blot mulige gør sig gældende som ontologisk realitet i vores erfaringsliv.       Udgivelsesdato: Efterår...

  11. Short note on the emergence of fractional kinetics

    Science.gov (United States)

    Pagnini, Gianni

    2014-09-01

    In the present Short Note an idea is proposed to explain the emergence and the observation of processes in complex media that are driven by fractional non-Markovian master equations. Particle trajectories are assumed to be solely Markovian and described by the Continuous Time Random Walk model. But, as a consequence of the complexity of the medium, each trajectory is supposed to scale in time according to a particular random timescale. The link from this framework to microscopic dynamics is discussed and the distribution of timescales is computed. In particular, when a stationary distribution is considered, the timescale distribution is uniquely determined as a function related to the fundamental solution of the space-time fractional diffusion equation. In contrast, when the non-stationary case is considered, the timescale distribution is no longer unique. Two distributions are here computed: one related to the M-Wright/Mainardi function, which is Green’s function of the time-fractional diffusion equation, and another related to the Mittag-Leffler function, which is the solution of the fractional-relaxation equation.

  12. Note on a Paper by Ooguri and Vafa

    Banks, Tom

    2016-01-01

    In a recent paper, Ooguri and Vafa [arXiv:1610.04564] argued that a mild extension of the Weak Gravity conjecture\\cite{weakgrav} led to the conclusion that the only models of quantum gravity in AdS space with "radius large compared to the string scale" were models with exact AdS-SUSY. This note clarifies certain obscure parts of their argument by reinterpreting it as a statement about brane configurations in flat space. In that context the statement is that stable non-supersymmetric configurations of branes are characterized by charges in the torsion subgroup of K-theory and their only long range fields are gravitational and scalar. The field equations do not have large radius near horizon AdS solutions. Instead the horizons are Schwarzschild black branes. This leads us to conjecture that for $d \\leq 11$ the K theory charges are bounded by a small integer, and there can be no large gravitational back reaction in the near horizon limit, for stable configurations. Unbounded values of these discrete charges woul...

    The magnitude of the flux superpotential W{sub flux} plays a crucial role in determining the scales of IIB string compactifications after moduli stabilisation. It has been argued that values of W{sub flux}≪1 are preferred, and even required for physical and consistency reasons. This note revisits these arguments. We establish that the couplings of heavy Kaluza-Klein modes to light states scale with the internal volume as g∼M{sub KK}/M{sub P}∼V{sup −2/3}≪1 and argue that consistency of the superspace derivative expansion requires gF/M{sup 2}∼m{sub 3/2}/M{sub KK}≪1, where F is the auxiliary field of the light fields and M the ultraviolet cutoff. This gives only a mild constraint on the flux superpotential, W{sub flux}≪V{sup 1/3}, which can be easily satisfied for O(1) values of W{sub flux}. This regime is also statistically favoured and makes the Bousso-Polchinski mechanism for the vacuum energy hierarchically more efficient.

  14. Eduard Schaubert's Travel Notes On Southern Euboea In May 1847

    Science.gov (United States)

    Goette, H. R.; Pajor, F.

    The German architect Eduard Schaubert (1804-1860), State Architect and Director of Public Works at King Otto's court, had a strong interest in archaeology. During his stay in Greece, between 1830 and 1850, Schaubert travelled abundantly throughout the country and studied its ancient ruins, architecture, sculpture, and inscriptions. In May/June 1847 he toured Southern Euboea visiting several sites (see appendix). His observations, written in notebooks, have never been published, but are of interest in several respects: What was to be seen, how was the condition of the monuments, how were they interpreted by other researchers before Schaubert and by himself and what sources did he use. In addition there are a number of excellent line drawings of monuments presenting detailed information about them. Eduard Schaubert's travel notes belong to the comprehensive surveying tradition of the island which begun in 1833 when Euboea passed by treaty from the Ottoman Empire to the newly founded Kingdom of Greece. The government's objective was not only a profound knowledge of ancient Greece, it was also striving to bring about the country's economic and urban revival. The two presentations, given at the conference in Styra, are focussing on Schaubert's observations. They are part of a wider research project on the architect's travels in Euboea, the Northern Sporades (1847) and Boeotia (1848). The forthcoming critical edition will provide an insight of his life as an architect, town planner, and archaeologist.

  15. A Note on the Magnitude of the Flux Superpotential

    Cicoli, Michele; Maharana, Anshuman; Quevedo, Fernando

    2013-01-01

    The magnitude of the flux superpotential $W_{flux}$ plays a crucial role in determining the scales of IIB string compactifications after moduli stabilisation. It has been argued that values of $W_{flux}$ much less than one are preferred, and even required for physical and consistency reasons. This note revisits these arguments. We establish that the coupling (g) of heavy Kaluza-Klein modes to light states scales as ${M_{KK} / M_{Pl}}$ (hence is suppressed by two third powers of the inverse volume of compactification) and argue that consistency of the superspace derivative expansion requires $gF/M^2 \\sim m_{3/2}/ M_{KK} << 1$, where $F$ is the auxiliary field of the light fields and $M$ the ultraviolet cutoff. This gives only a mild constraint on the flux superpotential, $W_{flux} << V^{1/3}$ (where V is the volume of the compactification), which can be easily satisfied for order one values of $W_{flux}$. This regime is also statistically favoured and makes the Bousso-Polchinski mechanism for the v...

  16. Notes on "quantum gravity" and non-commutative geometry

    CERN Document Server

    Gracia-Bondia, Jose M

    2010-01-01

    I hesitated for a long time before giving shape to these notes, originally intended for preliminary reading by the attendees to the Summer School "New paths towards quantum gravity" (Holbaek Bay, Denmark, May 2008). At the end, I decide against just selling my mathematical wares, and for a survey, necessarily very selective, but taking a global phenomenological approach to its subject matter. After all, non-commutative geometry does not purport yet to solve the riddle of quantum gravity; it is more of an insurance policy against the probable failure of the other approaches. The plan is as follows: the introduction invites students to the fruitful doubts and conundrums besetting the application of even classical gravity. Next, the first experiments detecting quantum gravitational states inoculate us a healthy dose of skepticism on some of the current ideologies. In Section 3 we look at the action for general relativity as a consequence of gauge theory for quantum tensor fields. Section 4 briefly deals with the...

  17. Notes on the Conway-Kochen Twin Argument

    CERN Document Server

    Adler, S L

    2006-01-01

    These notes (apart from an added comment at the end) were written in response to an earlier version of the Conway-Kochen paper; I believe they are equally relevant to the current version posted by Conway and Kochen as quant-ph/0604079, and so I am posting them on the Archive in the interest of stimulating a wider discussion. In them I give a reformulation of the part of the Conway-Kochen result that closes the contextuality loophole in the original Kochen-Specker (KS) theorem. I then argue that by neglecting the finite time needed to perform a measurement, Conway and Kochen are incorrect in their wider assertion that ``the particles' response to a certain type of experiment is not determined by the entire previous history of the part of the universe accessible to them.'' This assertion is needed by them to reach their conclusion that objective state vector reduction models cannot have a relativistic extension. Thus, I believe that the question of whether one can make a relativistic reduction model is still un...

  18. Notes on Lithology, Mineralogy, and Production for Lunar Simulants

    The creation of lunar simulants requires a very broad range of specialized knowledge and information. This document covers several topic areas relevant to lithology, mineralogy, and processing of feedstock materials that are necessary components of the NASA lunar simulant effort. The naming schemes used for both terrestrial and lunar igneous rocks are discussed. The conflict between the International Union of Geological Sciences standard and lunar geology is noted. The rock types known as impactites are introduced. The discussion of lithology is followed by a brief synopsis of pyroxene, plagioclase, and olivine, which are the major mineral constituents of the lunar crust. The remainder of the text addresses processing of materials, particularly the need for separation of feedstock minerals. To illustrate this need, the text includes descriptions of two norite feedstocks for lunar simulants: the Stillwater Complex in Montana, United States, and the Bushveld Complex in South Africa. Magnetic mineral separations, completed by Hazen Research, Inc. and Eriez Manufacturing Co. for the simulant task, are discussed.

  19. Notes on the Polynomial Identities in Random Overlap Structures

    Science.gov (United States)

    Sollich, Peter; Barra, Adriano

    2012-04-01

    In these notes we review first in some detail the concept of random overlap structure (ROSt) applied to fully connected and diluted spin glasses. We then sketch how to write down the general term of the expansion of the energy part from the Boltzmann ROSt (for the Sherrington-Kirkpatrick model) and the corresponding term from the RaMOSt, which is the diluted extension suitable for the Viana-Bray model. From the ROSt energy term, a set of polynomial identities (often known as Aizenman-Contucci or AC relations) is shown to hold rigorously at every order because of a recursive structure of these polynomials that we prove. We show also, however, that this set is smaller than the full set of AC identities that is already known. Furthermore, when investigating the RaMOSt energy for the diluted counterpart, at higher orders, combinations of such AC identities appear, ultimately suggesting a crucial role for the entropy in generating these constraints in spin glasses.

  20. Field note from Tajikistan Compound disaster - A new humanitarian challenge?

    Directory of Open Access Journals (Sweden)

    2009-04-01

    Full Text Available During the winter of 2007-2008 the Central Asian country of Tajikistan experienced an unusually cold winter which led to shortages of electricity, water and heating as well as food losses and these impacts occurred at the same time as a combined with a drought, and dramatically increased food prices and increased food insecurity. These impacts were exacerbated by a lack of investment in the water, power and fuel supplies, health care and education systems since independence in 1991. This combination of events was termed a compound disaster. The note explores the conditions in Tajikistan which created the compound disaster, the humanitarian response and how this disaster became a neglected event. The concept of compound disaster has gained limited acceptance in Central Asia but may also be applicable elsewhere. The difficulty of identifying and responding to a compound disaster creates a particular challenge for humanitarian organisations if they are to be effective in reducing human su%ering due to disasters.
