Quantifying the response of vertebral bodies to compressive loading using digital image correlation
Creators: name: Gustafson, Hannah Marie
Publisher: name: University of British Columbia
Year: 2016

description: Understanding vertebral mechanics is of interest for identifying persons at risk of fracture, whether that is due to everyday loading such as in osteoporotic fracture or as a result of dynamic loading leading to a traumatic fracture. Vertebral fractures negatively impact the quality life of patients and represent a large financial burden on the healthcare system. A powerful but underutilized tool that can be used to study vertebral loading and fracture is digital image correlation (DIC). DIC is a non-contact optical method for measuring the displacement on the surface of materials, including bone. In this thesis, DIC was used in a laboratory setting to provide a more complete understanding of the response of vertebral bodies to compressive loading. The first investigation compared measurements from DIC with strain gages, a commonly accepted experimental method for measuring the bone surface response. For porcine vertebral bodies, the agreement was strong between the strain gages and DIC-measured strains indicating that DIC can be successfully used on bone. Based on those findings, experimental studies were performed using DIC to identify fracture of the anterior cortex and to quantify rate-dependency of the vertebral body response. For the fracture study, high DIC strains on the anterior cortex of vertebral bodies corresponded well with the locations of damage identified by observation of the video. For the rate-dependency study, the DIC displacement patterns were similar for the slow and fast rate tests, but the displacements from the slow rate tests had higher magnitudes, as expected for viscoelastic materials such as bone. Finally, specimen-specific finite element (FE) vertebral body models were created and DIC was used to validate the displacement and stiffness response. The FE models were predictive of the experimental stiffnesses measured using DIC on the surface of the vertebrae. This thesis demonstrates the utility of DIC for experimental vertebral body investigations and for validation of FE models. Through these studies and future work, DIC has advanced and will continue to advance the understanding of vertebral mechanics under everyday loads as well as in simulated osteoporotic and healthy bone trauma.

description: Diffuse large B cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphomas, accounting for about 30-58% of all cases. In recent years, significant knowledge about the pathobiology of DLBCL has been gained. In particular, as a result of Gene Expression Profile (GEP) analysis, this disorder can be subdivided into diverse molecular subtypes. Unique lesions implicated in this disease’s pathobiology have been reported by the means of new technologies such as next-generation whole genome/exome sequencing. Our review focuses on the genetic alterations that are most commonly observed in this malignancy and have been functionally interpreted.

description: Measurements of anisotropic flow in heavy-ion collisions provide evidence for the creation of strongly interacting matter which appears to behave as an almost ideal fluid. Anisotropic flow signals the presence of multiple interactions and is very sensitive to the initial spatial anisotropy of the overlap region in non-central heavy-ion collisions. In this article we report measurements of elliptic $v_2$, triangular $v_3$, quadrangular $v_4$ and pentagonal $v_5$ flow. These measurements have been performed with 2- and multi-particle correlation techniques.

description: In this paper a scheme for offline Handwritten Devnagari Character Recognition is proposed, which uses different feature extraction methodologies and recognition algorithms. The proposed system assumes no constraints in writing style or size. First the character is preprocessed and features namely : Chain code histogram and moment invariant features are extracted and fed to Multilayer Perceptrons as a preliminary recognition step. Finally the results of both MLP's are combined using weighted majority scheme. The proposed system is tested on 1500 handwritten devnagari character database collected from different people. It is observed that the proposed system achieves recognition rates 98.03% for top 5 results and 89.46% for top 1 result.

description: Probe-level microarray data are usually stored in matrices, where the row and column correspond to array and probe, respectively. Scientists routinely summarize each array by a single index as the expression level of each probe set (gene). We examine the adequacy of a unidimensional summary for characterizing the data matrix of each probe set. To do so, we propose a low-rank matrix model for the probe-level intensities, and develop a useful framework for testing the adequacy of unidimensionality against targeted alternatives. This is an interesting statistical problem where inference has to be made based on one data matrix whose entries are not i.i.d. We analyze the asymptotic properties of the proposed test statistics, and use Monte Carlo simulations to assess their small sample performance. Applications of the proposed tests to GeneChip data show that evidence against a unidimensional model is often indicative of practically relevant features of a probe set.

description: Background: The metopic suture (MS), at the vertical axis between the two halves of the frontal bone appears as the result of lack of ossification. Its persistence is called metopism. The current study records the frequency of MS persistence, its morphological variants, and its coexistence with Wormian bones (WBs) in adult skulls. Material – Method: Eighty (41 male and 39 female) Greek adult dried skulls were investigated for the MS presence. For a further MS evaluation, the skulls were divided into 3 groups: 1st group (MS absence), 2nd group (complete MS) and 3rd group (incomplete MS). The incomplete MS was classified into the following morphological variants: Y, V, U, H shapes and linear and double linear types. Skulls used were also inspected for the WBs presence. Results: The MS was identified in 69 skulls (86.25%). Its absence was found in 11 skulls (13.8%) with similar frequencies in males and in females. The incomplete MS was prevalent (78.8%), while the complete one (metopism) was recorded in 7.5%. The incomplete MS dominant type was the linear (26.3%) followed by the V-type (17.5%), the double linear (15%), the H-type (8.8%), the U-type (6.3%) and the Y-type (5%). A percentage of 20% of the skulls had WBs in the lambdoid suture. A unique trigonocephaly case was identified with WBs in the lambdoid suture. Conclusion: The knowledge of MS persistence is valuable in clinical practice, as it can be erroneously considered as a frontal bone fracture in imaging studies. Neurosurgeons are obliged to be aware of this variant to provide the patient with the most appropriate and safe care. Furthermore, metopism is important in paleo-demography and forensic medicine.

description: Germany welcomed over a million refugees following the so-called ‘long summer of migration’ in 2015. Today, however, seeking asylum in Germany has become ever more difficult. Amongst other ‘undeserving’ economic refugees, the Afghans and Pakistanis are suffering from a shift in the German asylum regime that aims to restrict migration from ‘safe countries.’ As elsewhere in Europe, asylum in Germany is increasingly being defined by narrow ideas of deservingness and humanitarianism to seek out ‘deserving’ political refugees. Simultaneously, two methods for the removal of rejected asylum seekers are being practised to deter ‘undeserving’ refugees: namely, deportations and ‘voluntary’ returns. Focusing on the latter form of removal, I scrutinize the voluntariness and sustainability of ‘voluntary’ returns to Pakistan in this essay. I start by questioning contemporary ideas of deservingness when it comes to the right to be mobile, and provocatively try to blur the alleged humanitarian division between two categories of mobile bodies: the ‘deserving’ political refugee vis-à-vis the ‘underserving’ economic refugee. Then, with the help of ethnographic material from my ongoing research and three measures or scales of assessment (choice, information and assistance), I take a critical look at ‘voluntary’ returns from Germany. In doing so, I discuss the sustainability and ethics of inducing return through such modes of repatriation to Pakistan.

description: Purpose: The is to clarify the role of IL-10 and CD46 in recurrent pregnancy loss (RPL), via an immunohistochemical case-control study in placenta tissues. Materials and Methods: This is a case-control study in which the experimental group consisted of 20 women, 30 to 42 years old, who miscarried during the first trimester of pregnancy for unknown reasons, while the control group consisted of 20 women, 27 to 39 years old, who had voluntarily performed in termination of pregnancy in the first trimester. An immunohistochemical study was performed on histological samples of decidua basalis, decidua parietalis and trophoblast, using the immunohistochemical markers IL-10 and CD46. The results were statistically analyzed by the Mann-Whitney test. Results: A statistically significant difference in IL-10 expression was detected between the control group and the miscarriage group on decidual cells (p-value .0001). There was increased immunohistochemical staining on the decidua of the control group in comparison to the miscarriage group. Regarding CD46, the immunohistochemical analysis did not reveal a statistically significant difference between the two groups in either the decidual or trophoblastic cells. Conclusion: IL-10 seems to be associated with the RPL phenomena. It is necessary to further investigate the involvement of immune factors with RPL.

A study of the influence of assertions and mutants on test suite effectiveness
Creators: name: Zhang, Yucheng
Publisher: name: University of British Columbia
Year: 2016

description: Test suite effectiveness is measured by assessing the portion of faults that can be detected by tests. To precisely measure a test suite’s effectiveness, one need to pay attention to both tests and the set of faults used. Code coverage is a popular test adequacy criterion in practice. Code coverage, however, remains controversial as there is a lack of coherent empirical evidence for its relation with test suite effectiveness. More recently, test suite size has been shown to be highly correlated with effectiveness. However, previous studies treat test methods as the smallest unit of interest, and ignore potential factors influencing the correlation between test suite size and test suite effectiveness. We propose to go beyond test suite size, by investigating test assertions inside test methods. First, we empirically evaluate the relationship between a test suite’s effectiveness and the (1) number of assertions, (2) assertion coverage, and (3) different types of assertions. We compose 6,700 test suites in total, using 24,000 assertions of five real-world Java projects. We find that the number of assertions in a test suite strongly correlates with its effectiveness, and this factor positively influences the relationship between test suite size and effectiveness. Our results also indicate that assertion coverage is strongly correlated with effectiveness. Second, instead of only focusing on the testing side, we propose to investigate test suite effectiveness also by considering fault types (the ways faults are generated) and faults in different types of statements. Measuring a test suite’s effectiveness can be influenced by using faults with different characteristics. Assessing test suite effectiveness without paying attention to the distribution of faults is not precise. Our results indicate that fault type and statement type where the fault is located can significantly influence a test suite’s effectiveness.
Grieving geographies, mourning waters : race, gender and environmental struggles on the coast of Oaxaca, Mexico

description: This dissertation explores the ecocide of the Chacahua-Pastoría Lagoons in the Pacific Coast of Oaxaca, Mexico and its economic, social, and emotional impact on the Black and Indigenous women. Based on 14 months of fieldwork in the region, I argue that mestizaje—an homogenizing project and the foundational myth of the Mexican nation-state––shapes how Black and Indigenous communities experience violence and the dispossession of their lands, through what I call necro-mestizaje. The potential loss of the lagoons and the loss of community members due to violence are related social phenomena that produce collective grief that is both racialized and gendered and manifests acutely in Black and Indigenous women’s stories. Black and Indigenous women in the region seek to transform their personal and collective grief into political mobilization and seek strategies for the continuation of the life of their communities, their land, and the water. I name these spaces of grief as grieving geographies. These women create inter-ethnic alliances (like mutual-aid initiatives) and perform collective care towards the lagoons to disrupt the economic, social, and political consequences of ecocide. In other words, grief is the catalyst of local organizing for the preservation of the lagoons and produces local counter-hegemonic narratives against environmental racism. These narratives are strategies of survival and as well as a response to a matrix of violence in the region: racism, sexism, narcotrafficking, and ecocide. This dissertation is aligned with activism and collaboration with Black and Indigenous women’s organizations and community labor. My research methods include participant observation, oral histories, semi-structured interviews, and participatory community mapping. Through body-maps, a feminist geography methodology of mapping, local women illustrate the intimate relationship between their own bodies, the lagoons, and the community. These body-maps also challenge the whitening project of mestizaje that erases Black and Indigenous territoriality. I also reflect on my positionality and my own experience with grief throughout the research project. This dissertation aims to contribute to the literature on environmental racism and dispossession in Latin America, the anthropology of emotions, and feminist ethnography and geography, where emotions are centered as catalysts for local political mobilization.

description: We describe here a library aimed at automating the solution of partial differential equations using the finite element method. By employing novel techniques for automated code generation, the library combines a high level of expressiveness with efficient computation. Finite element variational forms may be expressed in near mathematical notation, from which low-level code is automatically generated, compiled and seamlessly integrated with efficient implementations of computational meshes and high-performance linear algebra. Easy-to-use object-oriented interfaces to the library are provided in the form of a C++ library and a Python module. This paper discusses the mathematical abstractions and methods used in the design of the library and its implementation. A number of examples are presented to demonstrate the use of the library in application code.
Robust estimation of tree structured probabilistic graphical models

Robust estimation

description: Undirected probabilistic graphical models or Markov Random Fields (MRFs) are a powerful tool for describing high dimensional distributions using an associated dependency graph 𝔾, which encodes the conditional dependencies between random variables. They form the starting point for many efficient estimation and inference algorithms. Thus, learning the graphical model of a collection of random variables from their samples is a fundamental, and very well-studied problem. In this thesis, we study a natural variant of this problem - learning the graph structure when the random variables have independent unknown noise. We investigate this problem for the class of tree structured graphical models. In the first problem, the task is to estimate tree structured Gaussian graphical models from samples which have additive independent Gaussian noise of unknown variance. The noise in different random variables breaks down the conditional independence relationship. We ask: can the original tree structure be recovered. We prove that this problem is unidentifiable, but show that this unidentifiability is limited to a small class of candidate trees. We further present additional constraints under which the problem is identifiable. In the second problem, we consider tree structured Ising models. The random variables in Ising models have support on {−1, +1}. We consider the task of learning Ising models when the signs of different random variables are flipped independently with possibly unequal, unknown probabilities. We prove that, surprisingly, the same limited unidentifiability results that hold for Gaussian graphical models continue to hold for Ising models. In the final problem, we study the natural extension of these problems - what happens in the case of graphical models on discrete random variables with larger support size. We show that the setting of support size of 3 or more is richer as the tree may be partially or fully identifiable. We provide a precise characterization of this phenomenon and show that the extent of recoverability is dictated by the joint PMF of the random variables. In particular, we provide necessary and sufficient conditions for exact recoverability. We provide an efficient algorithm to recover the tree upto the identifiability. Finally, we conclude with the sample complexity upper and lower bounds capturing the dependence of the number of samples on the underlying parameters.

description: Background: 3,4-methylenedioxymethamphetamine (MDMA), is a synthetic illicit psychostimulant drug that affects mood and social interactions. The aim of the present study is to investigate the in vitro effect of MDMA on human genetic material, by estimating sensitive cytogenetic indices. Methods: MDMA solutions (A=15μg/ml, B=30μg/ml, C=45μg/ml, D=60μg/ml, E=75μg/ml) were added in cultures of peripheral blood lymphocytes of four healthy donors. After 72 hours of incubation, the cultured lymphocytes were collected, plated on glass slides, stained with the Fluorescence plus Giemsa method and SCEs, PRI and MI were measured with the optical microscope. Sister Chromatid Exchanges (SCEs) is a sensitive marker of genotoxicity, Proliferation Rate Index (PRI) is a reliable marker of cytostatic activity and Mitotic Index (MI) is a reliable indicator of cell ability to proliferate. Results: Result analysis revealed: a) a statistically significant (p=0.001) reduction of SCEs on lower MDMA concentration and a significant induction (p=0.001) of SCEs after the effect of higher MDMA concentrations, b) PRI and MI reduction (p=0.001) after the effect of MDMA concentrations 45, 60 and 75μg/ml. Correlation was observed between a) SCE and PRI index variations, b) MI and SCE index variations and c) PRI and MI index variations. Conclusions: MDMA exhibited an interesting cytogenetic activity in vitro. It seems to affect human T lymphocytes by epigenetic and DNA replication modifications. This may provide additional information about the mechanism of action of the drug. Further studies in other cell lines and in vivo experimental settings are needed in order to evaluate its potential effects on human genetic material.

description: Origamis are covers of elliptic curves, ramified over at most one point. As they admit a flat atlas, they induce Teichmüller curves in the corresponding moduli spaces of curves. We compare geometric and arithmetic properties of these objects and study in detail a construction given by M. Möller which associates an Origami to a Belyi morphism. This leads to new examples, such as Galois orbits of Origami curves, and an infinite series of non-characteristic Origamis with Veech group SL(2,Z).

description: This work presents the application of weighted majority voting technique for combination of classification decision obtained from three Multi_Layer Perceptron(MLP) based classifiers for Recognition of Handwritten Devnagari characters using three different feature sets. The features used are intersection, shadow feature and chain code histogram features. Shadow features are computed globally for character image while intersection features and chain code histogram features are computed by dividing the character image into different segments. On experimentation with a dataset of 4900 samples the overall recognition rate observed is 92.16% as we considered top five choices results. This method is compared with other recent methods for Handwritten Devnagari Character Recognition and it has been observed that this approach has better success rate than other methods.

description: Backround: Mucha-Habermann disease, otherwise known as Pityriasis lichenoides et varioliformis acuta (PLEVA) is a rare cutaneous inflammatory disorder that usually presents as an acute eruption of inflammatory papules and papulovesicles with rapid progression to hemorrhagic or necrotic crusts. Cutaneous lesions may be asymptomatic, pruritic, or associated with a burning sensation. PLEVA commonly refers to a spectrum of inflammatory disorders. Case report: A diabetic 72 year old man was admitted for pruritic erythematous eruption with scaly maculopapules and ulceronecrotic - crusted lesions measuring 5–25 mm, localized on his trunk and lower extremities. The patient reported a relapsing and remitting course of the rash for one year. Laboratory investigation showed leukocytosis and CRP elevation. Viral serology liver and renal studies, C3, C4, serum protein electrophoresis, immunoglobulins, antinuclear antibodies and bacterial cultures were normal. Punch biopsy was performed. Histopathology showed parakeratosis, mild epidermal acanthosis, exocytosis of erythrocytes and lymphocytes, vacuolizasion of the basal layer, presence of necrotic keratinocytes and extensive lymphocytic inflammatory infiltrates. Diagnosis of PLEVA was established from the association of clinical and histological data. The patient received therapy with topical steroids, doxycycline, and methylprednisolone. Periodical follow up and annual consultation for a full skin examination was advised. Conclusion: PLEVA is a rare entity that presents difficulties in both diagnosis and treatment. Patients with refractory disease may require UVB phototherapy or methotrexate administration as an adjunct to first line treatment. Despite its benign and self-limiting course, it may be associated with cutaneous lymphoma, so annual full skin examination is indicated.

description: A new method of momentum measurement of charged particles through Multiple Coulomb Scattering (MCS) in the OPERA lead emulsion target is presented. It is based on precise measurements of track angular deviations performed thanks to the very high resolution of nuclear emulsions. The algorithm has been tested with Monte Carlo (MC) pions. The results are found to describe within the expected uncertainties the data obtained from test beams. We also report a comparison of muon momenta evaluated through MCS in the OPERA lead emulsion target with those determined by the electronic detectors for neutrino charged current interaction events. The two independent measurements agree within the experimental uncertainties, and the results validate the algorithm developed for the emulsion detector of OPERA.

description: Introduction: The Nursing Homes (NHs) for the elderly are closed structures accommodating elderly people, whether they are self-sufficient or not, and provide them the necessary daily care. During the SARS-CoV-2 [COVID-19] pandemic break out a number of sanitary measures implemented, so that the elderly people residing in those centres to be efficiently protected. Methodology: On-site inspections of the NHs were carried out from 01/01/2020 to 31/12/2020. An audit tool was used, adapted to the sanitary measures defined according to the current legislation, to verify and to monitor the implementation of those measures, thus ensuring the maximum possible accurate recording of compliance or failure of compliance with the sanitary rules. Results: On the completion of the NHs inspection, there were some regulation violations detected, regarding mandatory health protocols which were not applied. Therefore, fines were imposed accordingly. Out of the 95 NHs inspected, there were 12 charged with sanitary regulation violations and the fines imposed by Hellenic National Transparency Authority reached the amount of 69,000 euros. Conclusion: On-site inspection of the NHs in Greece showed that 87% of those complied with the SARS-CoV-2 [COVID-19] sanitary measures implemented, indicating that the majority of NHs operated according to the necessary hygienic rules.

description: Микозы стоп и кистей представляют собой не только эпидемиологическую и эстетическую проблему, но имеют весьма значимое клиническое значение. Цель: провести анализ организации профилактических мероприятий по выявлению микозов стоп и кистей среди населения Краснодарского края за 2011-2018 гг. Материалы и методы: анализ проводился на основе данных форм федерального статистического наблюдения № 34 «Сведения о больных заболеваниями передаваемыми преимущественно половым путем и заразными кожными заболеваниями», утв. приказом Росстата от 29.12.11 №520 (ред. от 24.12.2018) и формы № 9 «Сведения о заболеваниях инфекциями передаваемыми половым путем и заразными кожными болезнями», утв.приказом Росстата от 29.12.11 № 520 (ред. от 24.12.2018). Результаты: в динамике за 2011-2018 гг. в Краснодарском крае отмечается тенденция роста (на 68,2%) выявления пациентов с микозами стоп и кистей, большей части которых диагноз установлен при самостоятельном обращении в медицинские организации (96,8 %); 3% заболевших выявлено специалистами амбулаторно-поликлинических учреждений; 0,2% в условиях стационара. В форме №34 нет данных о случаях выявления заболевших микозами стоп и кистей в медицинских учреждениях других форм собственности. Анализ выявления микозов стоп и кистей специалистами разных профилей в амбулаторно-поликлинических учреждениях показал, что в динамике за 2011-2018 гг. в Краснодарском крае наблюдается тенденция к снижению (на 14,7%) числа заболевших микозами стоп и кистей, выявленных в кожно-венерологических учреждениях; на 5,2 % в других медицинских учреждениях; на 89,5 %-при всех видах медицинских осмотров. Выводы: в динамике за 2011-2018 гг. в Краснодарском крае число выявленных случаев заболевания микозами стоп и кистей увеличилось на 68,3% (в ЮФО-увеличение на 43,2%, а в РФ-снижение на 1,9%). В структуре путей выявления микозов стоп и кистей основная доля приходится на самостоятельное обращение (Краснодарский край 96,8%, ЮФО-79,1%, РФ-82,3%). Обращает на себя внимание низкий процент (всего 3,2%) активного выявления заболевших микозами стоп и кистей врачами медицинских организаций, в то время как в ЮФО и РФ аналогичный показатель был выше в 6,6 и 5,5 раза. При госпитализации в непрофильные стационары необходимо проводить работу по профилактике распространения микозов стоп и кистей путем активного выявления заболевших. Необходимо обеспечить учет пациентов с микозами стоп и кистей, обратившихся в медицинские организации других форм собственности.

description: We study a "strongly-coupled" (SC) polariton system formed between the atom-like intersubband transitions in a semiconductor nanostructure and the THz optical modes that are localised at the edges of a gold aperture. The polaritons can be excited optically, by incoherent excitation with bandgap radiation, and we find that they also coherently scatter the same input laser, to give strikingly sharp "sideband" (SB) spectral peaks in the backscattered spectrum. The SB intensity is a sensitive track of the polariton density and they can be detected down to a quantum noise floor that is more than 2500 times lower than the excitation thresholds of comparable quantum cascade laser diodes. Compared with other coherent scattering mechanisms, higher order SB scattering events are readily observable, and we speculate that the effect may find utility as a passive all-optical wavelength shifting mechanism in telecommunications systems.

description: The final aim of this commentary is to highlight the role of Aristotle’s model of virtue ethics as an approach of the modern bioethical dilemmas. Ultimately, and most importantly, it should be highlighted that virtue ethics and principlism are not mutually exclusive. In my opinion, this consideration must inform what we call “medical Ethos” referring to the spirit of the medical culture that is underpinning medical practice and professional ethics.

description: В статье приводятся результаты оригинального исследования отличий психологических характеристик выпускников Красноярского государственного медицинского университета им. проф. В.Ф. Войно-Ясенецкого, которые завершили обучение по специальности Фармация высшего и среднего профессионального образования от психологических характеристик выпускников медицинских специальностей. Цель исследования: выявить отличия личностных психологических профилей выпускников специальности Фармация высшего и среднего профессионального образования от личностных профессиональных профилей выпускников медицинских специальностей. Материалы и методы: отобраны опросники, дающие наибольшее число статистически значимых отличий между психологическими характеристиками выпускников с целью дальнейшего изучения влияния психологического профиля на работу в сфере фармацевтической деятельности: Мотиваторы, Деловой профиль DISС, Характерологический профиль (Шмишека-Леонгарда), тест Кеттелла, Динамические свойства (Русалов). Обработка данных была проведена на программном продукте IBM SPSS Statistics путем расчета критерия Манна-Уитни при p<0,05. Интерпретация результатов проводилась по шкалам и их описаниям используемых в исследовании психологических опросников. Результаты исследования. Выявлено, что среди всех опросников, по которым проведено сравнение психологических характеристик выпускников, наименее информативным для выявления отличий является опросник Деловой профиль DISC, так как он выявляет минимальное число статистически значимых отличий в психологических профилях выпускников специальности Фармация (ВО) по отношению к медицинским специальностям. Максимальное число статистически значимых отличий было выявлено в тесте Кеттелла. Выпускники специальности Фармация (ВО) более интровертны и сдержанны, менее склонны к общению по сравнению с выпускниками специальностей Лечебное дело, Педиатрия, Стоматология, Клиническая психология, Медицинская кибернетика, Выпускники-провизоры менее ориентированы на материальное благополучие, чем выпускники-стоматологи и менее ориентированы на доминирующее поведение, чем выпускники специальностей Стоматология, Лечебное дело и Клиническая психология. По сравнению с выпускниками-фармацевтами, выпускники-провизоры более склонны к умственной работе, а также менее чувствительны к несоответствию ожидания и реальных результатов работы. Так же навык обучаемости лучше выражен у выпускников-провизоров, чем у выпускников-фармацевтов.

description: Thermal leptogenesis and supergravity are attractive scenarios for physics beyond the standard model. However, it is well known that the super-weak interaction of the gravitino often leads to problems with primordial nucleosynthesis in the standard scenario of matter parity conserving MSSM + three right-handed neutrinos. We will present and compare two related solutions to these problems: 1) The conflict between BBN and leptogenesis can be avoided in presence of a hidden sector with light supersymmetric particles which open new decay channels for the dangerous long-lived particles. 2) If there is a condensate in the hidden sector, such additional decay channels can be alternatively opened by dynamical breaking of matter parity in the hidden sector.
