Time-consistent investment-proportional reinsurance strategy under a jump-diﬀusion model

In this paper, we formulate a mean-variance portfolio selection problem of an insurer who manages her underlying risk by purchasing proportional reinsurance and investing in a ﬁnancial market consisting of a bank account and a risky asset following jump-diﬀusion dynamics with random parameters. We then obtain a time-consistent equilibrium strategy via a ﬂow of backward stochastic diﬀerential equations. Finally, we apply our results to a mean-reverting L´evy-Ornstein-Uhlenbeck process and obtain closed form solutions.
Effect of Realistic Soil Moisture Initialization on the Canadian CanCM3 Seasonal Forecast Model

This paper presents the results of a direct comparison of sub-seasonal (60-day) forecast skill using two different land surface initializations in the Canadian Climate Centre for Modelling and Analysis (CCCma) CanCM3 coupled global climate model. The first land surface initialization uses randomized values of soil moisture whereas in the second case the model is initialized with a “best-estimate” of soil moisture derived from offline land surface model simulations. In this experiment the realistic soil moisture initialization improved temperature forecast skill during the boreal summer. Improvement was particularly evident for the wettest and driest quartiles of soil moisture initial conditions. Certain geographic regions, such as North America, showed the greatest improvement in temperature forecast skill. In contrast to temperature forecasts, there was much less skill improvement in precipitation forecasts between the two different soil moisture initializations, although there are geographic regions, such as North America, that do show increased skill. [Traduit par la rédaction] Cet article présente les résultats d'une comparaison directe de l'habileté des prévisions sous-saisonnières (60 jours) faites au moyen de deux initialisations de surface du terrain différentes dans le modèle couplé climatique global CanCM3 du Centre canadien de la modélisation et de l'analyse climatique (CCCma). La première initialisation de la surface du terrain se sert de valeurs d'humidité du sol choisies au hasard alors que dans le second cas, le modèle est initialisé à l'aide des « meilleures valeurs estimatives » d'humidité du sol dérivées de simulations modélisées hors ligne de la surface du terrain. Dans cette expérience, l'initialisation réaliste de l'humidité du sol a amélioré l'habileté des prévisions de température durant l’été boréal. L'amélioration était particulièrement évidente pour les quartiles le plus mouillé et le plus sec des conditions initiales d'humidité du sol. Certaines régions géographiques, comme l'Amérique du Nord, ont montré la plus forte amélioration dans l'habileté des prévisions de températures. Comparativement aux prévisions de température, il y avait beaucoup moins d'amélioration d'habileté dans les prévisions de précipitations entre les deux différentes initialisations d'humidité du sol, bien que certaines régions géographiques, comme l'Amérique du Nord, montrent une habileté accrue.
Objective and subjective olfactory dysfunction among COVID-19 inpatients and controls: a prospective, case-control study

Introduction: Olfactory dysfunction associated with COVID-19 infection is frequently described, but few studies utilize validated, objective tests or a control group. We compared rates of olfactory dysfunction between adults hospitalized with COVID-19 and controls admitted with similar upper respiratory symptoms who were COVID-19-negative. Methods: Hospital-ized (general ward) adults with upper respiratory symptoms who tested PCR positive or negative for SARS-CoV-2 completed the objective Brief Smell Identiﬁcation Test (BSIT; [? ]9 correct=normal) and subjective assessments while hospitalized and again at 3 month follow up. Comparison of groups was performed by t test or chi-square test of independence. Results: There were no diﬀerences in mean age or gender between groups (n=26 COVID, n=28 control). Both groups demonstrated objective olfactory dysfunction (mean BSIT 7.9 ± 2.8 COVID vs. 8.3 ± 3.2 control, p=0.62). Rates of both objective and subjective dysfunction did not signiﬁcantly diﬀer between groups. Follow up data at 3 months was limited (n=6 COVID, n=5), but showed 50% olfactory dysfunction in COVID patients compared to 20% in controls. Conclusions: SARS-CoV-2 and other viral illnesses serious enough to cause hospitalization cause olfactory dysfunction. Better understanding of the trajectory of chemosensory recovery will help elucidate the pathophysiology of viral-associated olfactory dysfunction and inform the care of patients suﬀering from its sequelae.
Comparative Study of Some Male and Female Jojoba Genotypes

: This investigation was conducted in the experimental orchard of Horticulture Research Institute, Agricultural Research Center, Giza, Egypt. Two experiments was set up to differentiate between male and female Jojoba . The first experiment (I): Identification of the difference between male and female nursery seedlings by using morphological traits. Seeds of jojoba were planted in 2016 and 2017 seasons. The second experiment (II), was carried out during 2019 and 2020 seasons, to study the in morphological and chemical difference between five genotypes of male and female shrubs was studied the vegetative growth, flowering number/m, seed production/plant, oil production/plant for female shrubs were also studied. Sub terminal stem cutting of the evaluated male and female shrubs was planted to study their rooting ability and fresh weight of roots, Leaves chemical analysis and molecular genetic identification between individuals of five males and five females by using RAPD and SCoT-PCR analysis. The results of growing the jojoba seedlings the percentage of male plants was (63.30% & 65.83%) higher than the female (36.7% & 43.16%) in the two seasons, respectively the ratio of male-to-female was nearly of (2:1). The results of comparing adult jojoba male and female characters indicated that the male's plants were superior than females in most of the tested vegetative characters. Moreover vegetative propagation by males stem cuttings achieved higher rooting percentage (46&49%) than females (26 & 29 %) and fresh weight of roots on males was greater than females. The superior male genotype G5 scored highest values of inflorescences/ meter (20.75 & 19.88) in the two studied seasons, female genotype G4 were superior than others in oil production (326.6 & 337.6g) in the two studied seasons . In this study we attempted to characterize molecular genetic identification and detection sex determination between individuals of five males and five females from Jojoba cultivar using two RAPD primers were used to amplify male and female individuals, the two primers were found to have sex specificity in analysis. However, three SCoT primers (SCoT 3, SCoT 7 and SCoT11) were found to have sex specificity for male in analysis. While, Primers (SCoT 2 and SCoT 5) were found to have sex specificity for female individual analysis.
MIT Open Access Articles In Silico Assessment of the effects of Material on Stent Deployment

Coronary stents are expandable scaffolds that are used to widen occluded diseased arteries and restore blood flow. Because of the strain they are exposed to and forces they must resist as well as the importance of surface interactions, material properties are dominant. Indeed, a common differentiating factors amongst commercially available stents is their material. Several performance requirements relate to stent materials including radial strength for adequate arterial support post-deployment. This study investigated the effect of the stent material in three finite element models using different stents made of: (i) Cobalt-Chromium (CoCr), (ii) Stainless Steel (SS316L)
Oldest Paleo-Tethyan ophiolitic mélange in the Tibetan Plateau

An early Paleozoic ophiolitic melange has recently been documented in the west Gangma Co area, north-central Tibetan Plateau. It is composed of serpentinite, isotropic and cumulate gabbros, basalt, and plagiogranite. Whole-rock geochemical data suggest that these rocks were formed in an oceanic-ridge setting, and the depletion in Nb and Ti indicates their suprasubduction zone nature. Furthermore, whole-rock e Nd ( t ) (+3.5 to +10.6) and zircon e Hf ( t ) values (+11.4 to +14.5) suggest that these rocks were derived from a long-term depleted mantle source. These geochemical features, combined with the rock types and their field relationships, suggest the rocks represent an ophiolite suite. Zircon U-Pb dating of isotropic gabbros and plagiogranites yielded weighted mean ages ranging from 437 to 501 Ma, which makes the west Gangma Co ophiolitic melange the oldest Paleo-Tethys ophiolitic melange in the Tibetan Plateau. The main Paleo–Tethys Ocean basin probably opened in the Middle Cambrian; it continued to grow throughout the Paleozoic and closed in the later Triassic. The Paleo–Tethys Ocean was formed by the breakup of the northern margin of Gondwana, with southward subduction of the proto-Tethys oceanic lithosphere along the northern margin of the supercontinent.
: Targets and Therapy

Background: The purpose of this study was to characterize cardiovascular risk factors in a rural pediatric population by body mass index (BMI) category and the presence of the metabolic syndrome. Methods: Data on 13,018 children and adolescents (aged younger than 20 years) from West Virginia and Ohio in 2005–2006 were obtained from the C8 Health Project to determine the prevalence of overweight/obesity and the metabolic syndrome, which was then compared with National Health and Nutrition Examination Survey 2005–2006 data. Cardiovascular risk factors were assessed by age-standardized and sex-standardized BMI category ( , 85th, 85th–95th, . 95th percentiles) and the presence of metabolic syndrome, defined as the presence of three or more of the following criteria: BMI . 97th percentile, triglycerides . 110 mg/dL, high-density lipoprotein cholesterol , 40 mg/dL, and fasting blood glucose . 110 mg/dL. Results: The population was 51% male and 95% white. The prevalence of overweight/obesity was 38% and metabolic syndrome was 4.6% in the C8 population, compared with a prevalence of 30% and 3.4%, respectively, within the National Health and Nutrition Examination Survey population. In our Appalachian population, a significant adverse trend across BMI categories was observed for lipids, insulin, inflammatory markers, white blood cell count, and C-reactive protein. Significant differences in these risk factors were seen among those with metabolic syndrome compared with those without metabolic syndrome. Conclusion: The increased prevalence of overweight/obesity and the metabolic syndrome along with the increase in cardiovascular risk factors in Appalachian children and adolescents, suggests a cohort that may develop earlier onset and possibly increased severity of cardiovascular disease and other complications associated with metabolic syndrome and obesity.
Templated Encapsulation of Pt-based Catalysts Promotes High-Temperature Stability to 1,100 °C

Stable catalysts are essential to address energy and environmental challenges, especially in harsh environment applications (high temperature, oxidizing atmosphere, steam). In such conditions, supported metal catalysts deactivate due to sintering – a process where initially small nanoparticles grow into larger ones with reduced active surface area. Strategies to stabilize them lead to decreased performance. Here, we report stable catalysts prepared through the encapsulation of platinum particles inside an alumina framework. These catalysts do not sinter at 800 °C in the presence of oxygen and steam, conditions in which conventional catalysts sinter to large extents, while showing similar reaction rates. Extending this approach to Pd/Pt bimetallic catalysts leads to maintained small particle size at temperatures as high as 1,100 °C in air and steam. This strategy can be broadly applied to other metal and metal oxides for applications where sintering is a major cause of materials deactivation.
sgRNA level is a major factor affecting CRISPRi knockdown efficiency in K562

—To determine how nuclease deactivated Cas9 (dCas9) or sgRNA expression 12 level affects the knockdown efficiency of CRISPRi, K562 cell clones expressing 13 KRAB-dCas9 protein either with the inducible Tet-on system or with the constitutive 14 SFFV promotor were created by lentiviral transduction, and single clones were selected 15 by fluorescence-activated cell sorting (FACS) for further study. Six genes with various 16 expression levels were targeted using lentiviral sgRNA from two libraries in four cell 17 clones with various KRAB-dCas9 expression levels. We determined the knockdown 18 efficiency and the expression level of the dCas9 protein /sgRNA level by flow 19 cytometry. The cell clone with the highest KRAB-dCas9 expression level achieved 20 effective CRISPRi knockdown, and is statistically different from other clones, 21 indicating enough KRAB-dCas9 expression might be a prerequisite for CRISPRi. 22 Utilizing this clone, we modified the expression level of sgRNA by adopting different 23 multiplicity of infection
Vocational Calling, Meaningful Work, and Job Satisfaction Among Disability Services Providers

: Recruiting and retaining a strong disability workforce remains an enduring concern in the field of intellectual and developmental disabilities. Yet little attention has focused on the sense of calling that disability service providers have to this important work and its relationships to their job satisfaction. We surveyed 269 disability service providers to examine whether they (a) perceive a calling in their life, (b) are living out that calling in their current work, (c) find meaning in their career, and (d) experience job satisfaction. The experience of both having and living out one’s calling in their current work was especially prominent among participants. Likewise, most providers indicated they drew considerable meaning and purpose from their work. Perceiving a calling contributed to higher job satisfaction through living out one’s calling and finding meaning in one’s work. Some variations in ratings were associated with personal demographics (i.e., sex, years of experience). These findings provide new insights into what might draw disability service providers into this work or sustains their commitment amidst challenging and changing working conditions. We highlight areas for research and practice aimed at place of calling within efforts to strengthening recruitment and retention.
Burnout syndrome among employees in a clinical center in Montenegro during COVID-19.

OBJECTIVE Burnout syndrome occurs as a result of the influence of stressors in the workplace. The chronic disproportion between the demands placed on the worker and the resources available to fulfill the demands makes a significant contribution to the development of this syndrome. The occurrence of burnout syndrome has been shown to occur in a wide range of jobs, and it is taking on epidemic proportions among healthcare workers. So far, there have been no large-scale studies dealing with burnout syndrome in healthcare workers in Montenegro. SUBJECTS AND METHODS The research was conducted as a cross-sectional study. All full-time employees of the Clinical Center of Montenegro who participated in the treatment of patients with COVID-19 during 2020 and 2021 were included in the research. Questionnaires used in the research were: a general questionnaire for collecting socio-demographic data, a questionnaire for the assessment of burnout syndrome at work - Maslach Burnout Inventory and a COVID-19 stress scale. RESULTS The prevalence of burnout syndrome was 16.8% among employees who were engaged around COVID-19 patients. Predictors of burnout syndrome identified were occupation (nurses/technicians have a 2.8 times higher chance of burnout syndrome than doctors as a reference category), confirmed COVID-19 infection (subjects with confirmed COVID-19 infection have more than 2 times higher chance for burnout syndrome), higher CSS scores (subjects with high CSS score have a 3% higher chance of developing burnout syndrome). CONCLUSIONS In order to reduce losses due to reduced productivity of employees and prevent long-term detrimental consequences on the mental health of employees, evidence-based preventive measures are needed.
Transformational Leadership, Communication Skill and Performance of Rural Companies: Moderated by Environmental Uncertainty

Purpose: Establishing companies in rural areas is one solution for equitable development. However, in reality, there are still many companies in rural areas that are not yet operating optimally. This is due to many factors. This research aims to analyze how transformational leadership and communication skills play a role in improving company performance in rural areas. Additionally examined in this study as a moderating factor is environmental uncertainty Design/Methodology/Approach: The population in this study was 57 rural companies in Indonesia spread across Riau Province. The sampling technique used is stratified sampling. Respondents in this study are company managers. A total of 137 respondents participated in this study. The data-gathering technique employs questionnaires, which are dispersed by delivering them directly to respondents. This study employs the partial least squares method to evaluate the hypothesis. Findings: According to data analysis, environmental uncertainty, communication abilities, and transformational leadership all have a effect on improving business performance. Environmental uncertainty moderates the impact of transformative leadership on corporate performance but not the impact of communication skills on company performance. Implications/Originality/Values: This research contributes to the importance of transformational leaders and communication skills to improve company performance in rural areas. Environmental factors must also be considered in making decisions. To form transformational leadership, leadership training is necessary.
Error-Bounded and Feature Preserving Surface Remeshing with Minimal Angle Improvement

The typical goal of surface remeshing consists in finding a mesh that is (1) geometrically faithful to the original geometry, (2) as coarse as possible to obtain a low-complexity representation and (3) free of bad elements that would hamper the desired application. In this paper, we design an algorithm to address all three optimization goals simultaneously. The user specifies desired bounds on approximation error , minimal interior angle and maximum mesh complexity N (number of vertices). Since such a desired mesh might not even exist, our optimization framework treats only the approximation error bound as a hard constraint and the other two criteria as optimization goals. More specifically, we iteratively perform carefully prioritized local operators, whenever they do not violate the approximation error bound and improve the mesh otherwise. Our optimization framework greedily searches for the coarsest mesh with minimal interior angle above and approximation error bounded by . Fast runtime is enabled by a local approximation error estimation, while implicit feature preservation is obtained by specifically designed vertex relocation operators. Experiments show that our approach delivers high-quality meshes with implicitly preserved features and better balances between geometric fidelity, mesh complexity and element quality than the state-of-the-art.
basic numerical capacities in children with difficulties in simple arithmetical achievement

Introduction: Current cognitive theories suggest that mathematical learning disabilities may be caused by a dysfunction in the ability to represent non-symbolic numerosity (non-symbolic skills), by impairments in the ability to associate symbolic numerical representations with the underlying analogic non-numerical magnitude representation (symbolic and numerical mapping skills), or by a combination of both deficits. The aim of this study was to contrast the number sense hypothesis and the access deficit hypothesis, to identify the possible origin of the varying degrees of arithmetical difficulties. Method: We compared the performance of children with very low arithmetic achievement (VLA), children with low arithmetical achievement (LA), and typically achieving peers (TA), in non-symbolic, symbolic and numerical mapping tasks. Intellectual capacity and working memory were also evaluated as control variables. The sample comprised 85 Chilean children (3rd to 6th grades) from the Public General Education System. Data were included in several covariance analyses to identify potentially different behavioural profiles between groups. Results: The results showed deficits in both non-symbolic numerosity processing and number-magnitude mapping skills in children with VLA, whereas children with LA exhibited deficits in numerical mapping tasks only. Conclusions: These findings support the hypothesis of impaired non-symbolic numerical representations as the cognitive foundation of severe arithmetical difficulties. Low arithmetical achievement, in contrast, seems to be better explained by defective numerical mapping skills, which fits the access deficit hypothesis. The results presented here provide new evidence regarding the cogni - tive mechanisms underlying the different behavioural profiles identified in children with varying degrees of arithmetical difficulties.

MIT Open Access

The imperative-and-declarative (IaD) construction in English (e.g., “Study hard and you will pass the class”) has two distinct readings: one which has the semantics of a conditional and additionally the meaning of an imperative, and one which has only the semantics of a conditional, with no imperative meaning. There are two general kinds of syntactic approaches in the literature for analyzing this construction: one that treats the two interpretations as underlyingly syntactically the same, and one that treats them as two distinct syntactic constructions. This paper reports the results of an acceptability judgment experiment that was designed to inform the debate between the two kinds of approaches. The two types of IaDs were observed to behave differently with respect to two phenomena we evaluated, suggesting that they should either be treated as grammatically distinct, or that a theory that treats them as grammatically the same must give a pragmatic account of the differences. Furthermore, because the pattern of data that we observed was an statistical interaction between two factors – a pattern of data that is not detectable without quantitative measurements – the results provide compelling evidence for the need for quantitative evaluations of linguistic hypotheses.
