description: Abstract: This article examines Kohlberg’s proposal of the “just community” from a current perspective in line with a post-conventional morality grounded on the democratization of schools. A type of teacher training is proposed that uses up-to-date methods to approach just communities. By taking the critical interpretation of the model of moral development, the article also concludes that schools today have integrated some of the cutting-edge advances to the just communities’ program, and that this approach reciprocally calls for updating the idea of moral education by incorporating a broader view of morality. Such an update also includes families in the joint process of stimulating moral development and resolving conflicts of action. Lastly, it has been explained that Kohlberg did not give the family a role in their children’s moral education, stating that the specific way to develop moral reasoning is through the relationships among equals at school. It is unclear whether there is a particular moral family environment that best fosters the development of the child’s moral reasoning. Nevertheless, data provided from some studies confirm that there is a relationship between the moral reasoning of the parentsand that of their children. Indeed, parents may even use teaching strategies to improve their children’s moral development through dialog and the use of inductive strategies.

Variation in metabolic rate between individuals and species : cryptic physiological tradeoffs underlying habitat partitioning and life history strategies of juvenile salmonids
Creators: name: Van Leeuwen, Travis Edward
Publisher: name: University of British Columbia
Year: 2010

description: Physiological traits such as standard metabolic rate have been shown to vary up to half an order of magnitude between individuals and species and influence key life history tradeoffs in juvenile salmonids (e.g. smolt timing). The purpose of my thesis research was to examine the relationship between food consumption, dominance and disproportionate feeding on physiological traits and adaptive strategies of juvenile salmonids. Results show that SMR is positively correlated with food consumption and growth in juvenile coho salmon which showed a reduction in SMR under low food and an elevation in SMR under high food (Chapter 2). Comparisons between hatchery and wild juvenile steelhead and coho salmon revealed no difference in Stnadard metabolic rate between wild coho and wild steelhead but a significant difference in the hatchery fish, with hatchery steelhead being higher. In both wild and hatchery populations I found a marked difference in maximal metabolic rate between steelhead and coho, leading to a greater aerobic scope and swim performance in wild steelhead but no difference in the hatchery fish. This result is consistent with a steelhead energy maximizing strategy, habitat partitioning and trade-offs between elevated SMR at higher growth and decreased swim performance. Interestingly, wild steelhead with higher maximum growth, swim performance, and maximum food consumption do not appear to tradeoff increased growth against lower swim performance, as commonly observed for high growth strains. Instead steelhead appear to be trading off higher growth for lower food consumption efficiency; highlighting potential differences in food consumption and digestion strategies as cryptic adaptations that have received little attention. In experiments conducted in semi-natural stream channels, I found that dominant coho salmon were able to achieve higher absolute growth rates compared to smaller subordinates, at high food ration but suffered significantly lower absolute growth at low food ration as larger dominant fish approached the capacity of their habitat (Chapter 4). Overall I demonstrated that the relationship between physiological traits, life history strategy and dominance rank depended on per capita food consumption rates, habitat characteristics (pools vs riffles) and the absolute size of individuals in a dominance hierarchy.

description: The communication capacity of Gaussian bosonic channels with memory has recently attracted much interest. Here, we investigate a method to prepare the multimode entangled input symbol states for encoding classical information into these channels. In particular, we study the usefulness of a Gaussian matrix product state (GMPS) as an input symbol state, which can be sequentially generated although it remains heavily entangled for an arbitrary number of modes. We show that the GMPS can achieve more than 99.9% of the Gaussian capacity for Gaussian bosonic memory channels with a Markovian or non-Markovian correlated noise model in a large range of noise correlation strengths. Furthermore, we present a noise class for which the GMPS is the exact optimal input symbol state of the corresponding channel. Since GMPS are ground states of particular quadratic Hamiltonians, our results suggest a possible link between the theory of quantum communication channels and quantum many-body physics.

description: Abstract: What happens when Corporate Social Responsibility (CSR) and Human Rights meet? This article argues that although CSR is a worthy attempt to propose social-aimed better practices for managerial decisions, a human rights perspective substantially enriches this vision. It also suggests that the ancient principle of res extra commercium can provide the rationale crucial to join CSR with human rights as a source of moral absolutes. Essentially, based on the res extra commercium rationale, businesses should start by identifying areas of economic activity that are off limits because they may violate human dignity.

Measurement and Modeling of Pentane-Diluted Bitumen Phase Behaviour

description: The phase behavior of mixtures of bitumens and n-alkanes is a key factor in the design and optimization of solvent-assisted heavy oil recovery processes and solvent deasphalting processes. However, data and comprehensive models are lacking for these mixtures. Crude oil phase behavior is typically modeled using cubic equations of state (CEoS). While CEoS have successfully fit saturation pressures and asphaltene onset points for bitumen-solvent systems using simple quadratic mixing rules; they do not accurately predict asphaltene precipitation yields. This thesis focuses on data collection and CEoS modeling with asymmetric mixing rules for mixtures of bitumen and n-pentane. Phase behavior data were collected for n-pentane diluted bitumen up to 14 MPa and 280°C. Saturation pressures were measured using both a PVT cell and a blind cell apparatus. The composition at which asphaltenes precipitate was measured using a high pressure microscope apparatus and was extrapolated from asphaltene yield data. A new experimental procedure was developed to measure the phase compositions of both the light phase and the asphaltene rich heavy phase at high temperature where two liquid phases are observed. A blind cell apparatus was designed to measure asphaltene yields for multiple samples simultaneously. Binary and ternary phase diagrams were generated from the data. The Advanced Peng Robinson (APR) CEoS with several sets of asymmetric and compositionally dependent mixing rules was evaluated using the aforementioned dataset. The use of asymmetric mixing rules significantly improved the match to asphaltene yield data; however, the yields were still under-predicted at high solvent contents and the tuning parameters that gave the best match for asphaltene yield data were not predictive or easily correlated for other solvents. The use of compositionally dependent solvent/asphaltene binary interaction parameters allowed the model to fit asphaltene yield data over the entire composition range. A set of interaction parameters was recommended that fits both asphaltene yield and saturation pressure data. While successful at fitting the data, this approach is not practical for many simulation applications and the overall conclusion is that CEoS are not well suited for the full range of bitumen-solvent phase behavior.

description: Link directions are essential to the functionality of networks and their prediction is helpful towards a better knowledge of directed networks from incomplete real-world data. We study the problem of predicting the directions of some links by using the existence and directions of the rest of links. We propose a solution by first ranking nodes in a specific order and then predicting each link as stemming from a lower-ranked node towards a higher-ranked one. The proposed ranking method works recursively by utilizing local indicators on multiple scales, each corresponding to a subgraph extracted from the original network. Experiments on real networks show that the directions of a substantial fraction of links can be correctly recovered by our method, which outperforms either purely local or global methods.

description: © 2020 by the authors. Licensee MDPI, Basel, Switzerland. The human microbiota shows pivotal roles in urologic health and disease. Emerging studies indicate that gut and urinary microbiomes can impact several urological diseases, both benignant and malignant, acting particularly on prostate inflammation and prostate cancer. Indeed, the microbiota exerts its influence on prostate cancer initiation and/or progression mechanisms through the regulation of chronic inflammation, apoptotic processes, cytokines, and hormonal production in response to different pathogenic noxae. Additionally, therapies’ and drugs’ responses are influenced in their efficacy and tolerability by microbiota composition. Due to this complex potential interconnection between prostate cancer and microbiota, exploration and understanding of the involved relationships is pivotal to evaluate a potential therapeutic application in clinical practice. Several natural compounds, moreover, seem to have relevant effects, directly or mediated by microbiota, on urologic health, posing the human microbiota at the crossroad between prostatic inflammation and prostate cancer development. Here, we aim to analyze the most recent evidence regarding the possible crosstalk between prostate, microbiome, and inflammation.

description: The Generalized Extreme Value (GEV) distribution is the most commonly used distribution for analyzing extreme values. However, the existing GEV models are based on the assumption that the extreme values are independent, which is sometimes not the case in real data analysis. This thesis aims to overcome this issue by bringing forward a new GEV model that considers the correlation between two successive extreme values. The proposed model can be applied to both independent and dependent extreme values. The point estimation and interval estimation methods for the model parameters are introduced. Simulation studies describe the estimation performance under different combinations of parameters and show that the proposed methods have better performance than the traditional GEV model. Moreover, a study of the Average Run Length (ARL) for the GEV model is conducted through simulation. In the end, two real data analyses are included to illustrate the application of our methodology.

description: We study the interplay of thermal and diffractive effects in Casimir energies. We consider plates with edges, oriented either parallel or perpendicular to each other, as well as a single plate with a slit. We compute the Casimir energy at finite temperature using a formalism in which the diffractive effects are encoded in a lower dimensional non-local field theory that lives in the gap between the plates. The formalism allows for a clean separation between direct or geometric effects and diffractive effects, and makes an analytic derivation of the temperature dependence of the free energy possible. At low temperatures, with Dirichlet boundary conditions on the plates, we find that diffractive effects make a correction to the free energy which scales as T^6 for perpendicular plates, as T^4 for slits, and as T^4 log T for parallel plates.

description: Abstract: Fintech have irrupted around the world. This paper proposes an analysis of the mechanism of influence of the salient factors of the Fintech phenomenon on user confidence in Fintech companies. This represents a barrier for an increased use and adoption of Fintech services in financial markets, which represent an opportunity for Fintech to become part of the mainstream of access to financial services with a greater ethical and inclusive commitment. We have designed an analysis of the Fintech web platforms from a trust and ethical view. The consensus shows that all six factors influence user confidence, relevant for ethical behaviour because trustworthy if the first step that flourish the well doing and trustbase collaboration between parties. However, it is the risk (security, privacy and financial) where there is a perfect consensus, while financial inclusion presents a consensus with a greater dispersion of opinions. Fintech firms need to ensure that the tools they are building are trustworthy and safe and that their business models do not abuse customer relationships by selling data, maintaining a lack of security protocols and other inappropriate and unethical practices. Therefore, this study contributes to the literature on Fintech’s development by providing a comprehensive analysis of the user-Fintech interrelationship and the incorporation of the determinants influencing trust as a critical and complementary element in the technology acceptance model (TAM). This paper contributes to the ethical relationship based on trust.

description: The primary objective of this study was to quantify and map the biological contamination within private hospital rooms at Foothills Medical Center in Calgary Alberta. Secondary objectives were to assess the ability of two common cleaning products to remove biological contamination from surfaces as well as compare two methods of measuring housekeeping efficacy (UV gel and microbiological sampling techniques). Researchers covertly observed 9 housekeepers terminally clean 31 private rooms. Assessment took place using microbial swabbing and UV gel technology to evaluate cleanliness. Results suggest that the type of cleaning product does not make an impact, and that cleaning technique may be of higher importance. Lastly, the use of UV gel is may not be a suitable substitute for measuring a reduction of microbial contamination.
Effects of conical intersections on hyperfine quenching of hydroxyl OH in collision with an ultracold Sr atom

Publisher: name: My University
Year: 2020

description: © 2020, The Author(s). The effect of conical intersections (CIs) on electronic relaxation, transitions from excited states to ground states, is well studied, but their influence on hyperfine quenching in a reactant molecule is not known. Here, we report on ultracold collision dynamics of the hydroxyl free-radical OH with Sr atoms leading to quenching of OH hyperfine states. Our quantum-mechanical calculations of this process reveal that quenching is efficient due to anomalous molecular dynamics in the vicinity of the conical intersection at collinear geometry. We observe wide scattering resonance features in both elastic and inelastic rate coefficients at collision energies below kB×10mK. They are identified as either p- or d-wave shape resonances. We also describe the electronic potentials relevant for these non-reactive collisions, their diabatization procedure, as well as the non-adiabatic coupling between the diabatic potentials near the CIs.
A Cordial Approach to the Duty of Rescue. The Case of EU States’ Moral Obligations in the Mediterranean Crisis of 2014-2016
Creators: name: Corrales Trillo, Bosco
Publisher: name: Ramon Llull Journal of Applied Ethics

description: Abstract: In 2014, the EU States decided not to support Italy’s Mare Nostrum search and rescue operation and neither replace it with an equivalent mission nor take any other effective action to prevent a massive loss of lives in the Mediterranean Sea in 2015. From the perspective of a standard account of the duty of rescue and a conservative notion of humanitarian duties, the EU states did not have a moral obligation to engagein such actions. The reasons for such a lack of obligation would mainly be three: first, the potential rescuers did not physically encounter nor were they in close vicinity of the victims; secondly, the obligation -if any- would have been a collective one, so no individual actor had a specific obligation to search and rescue; thirdly, the cost of the operation was too high. My argument is that, based on Adela Cortina’s notion of cordial reason, which hinges on a compassionate recognition of human dignity, the EU States had a moral obligation to support the Mare Nostrum operation or at least to effectively prevent a more than likely massive loss of lives in the Mediterranean. Cordial reason allows us to respond to the above mentioned three reasons. Firstly, although the potential rescuers did not physically encounter the victims, they had the ability and the skills to save them if they had wanted to do so; secondly, the collective obligation is not primary, but a result of the obligation that any human being owes to another fellow human being; and thirdly, the duty of rescue -understood in the light of cordial reason- is not subject to cost limitations.

Simple hydrogenic estimates for the exchange and correlation energies of atoms and atomic ions, with implications for density functional theory
Creators: name: (:Unkn) Unknown
Publisher: name: My University
Year: 2020
Subjects: physics.chem-ph

description: © 2020 Author(s). Exact density functionals for the exchange and correlation energies are approximated in practical calculations for the ground-state electronic structure of a many-electron system. An important exact constraint for the construction of approximations is to recover the correct non-relativistic large-Z expansions for the corresponding energies of neutral atoms with atomic number Z and electron number N = Z, which are correct to the leading order (-0.221Z5/3 and -0.021Z ln Z, respectively) even in the lowest-rung or local density approximation. We find that hydrogenic densities lead to Ex(N, Z) ≈ -0.354N2/3Z (as known before only for Z ≫ N ≫ 1) and Ec ≈ -0.02N ln N. These asymptotic estimates are most correct for atomic ions with large N and Z ≫ N, but we find that they are qualitatively and semi-quantitatively correct even for small N and N ≈ Z. The large-N asymptotic behavior of the energy is pre-figured in small-N atoms and atomic ions, supporting the argument that widely predictive approximate density functionals should be designed to recover the correct asymptotics. It is shown that the exact Kohn-Sham correlation energy, when calculated from the pure ground-state wavefunction, should have no contribution proportional to Z in the Z → ∞ limit for any fixed N.
The dynamical fingerprint of gas-expulsion: Insights into the assembly of the Milky Ways' old GC system

description: Since the oldest globular clusters (GCs) are early residuals from the formation of the Milky Way (MW), GCs were exposed to the likely evolving potential of our Galaxy. The expulsion of the residual-gas from the GC's embedded progenitors is sensitive to the conditions in the pre-MW gas cloud. By means of N-body computations it is shown that gas throw-out from initially mass-segregated GCs affect the shape of the low-mass stellar mass function (MF) and that its imprint might still be visible in the present-day MF (PDMF). The strength of the tidal-field at birth influences the degree of gas-expulsion driven low-mass-star depletion and therefore the PDMF probes the MW potential at the time of GC formation. It is argued that among the old GC population in the MW, younger GCs show stronger low-mass-star loss than older GCs. This is shown to be consistent with a contracting and self-gravitating cloud in which fluctuations in the pre-MW potential grow with time. An initially relatively smooth tidal field evolved into a grainy potential within a dynamical time-scale of the collapsing cloud (based on Marks & Kroupa 2010, MNRAS, 406, 2000).

Introduction A growing number of children and young people are surviving severe acquired brain injuries due to advances in healthcare. However, many fail to emerge from coma and continue to live with disorders of consciousness (DOC). Diagnostic, clinical and ethical challenges are prominent in this group. Misdiagnosis can have severe consequences for children and their families, including inadequate care, insufficient access to rehabilitation and stimulation, reduced accessibility to services and inappropriately limited opportunities for participation. The proposed project will develop and validate a diagnostic measure that supports detailed goal-planning-the Music therapy Sensory Instrument for Cognition, Consciousness and Awareness (MuSICCA). Methods and analysis Face validity will be assessed using a short questionnaire and the MuSICCA will be amended if face validity is insufficient. Once face validity is sufficient, 80 participants with suspected DOC will be recruited from multiple sites around the UK, USA and Ireland. Validity will be assessed using external reference standards (Coma Recovery Scale-Revised, Coma Near-Coma Scale and Nociception Coma Scale). Intra-rater reliability will be established using repeated ratings of video recordings from the assessment sessions. Inter-rater reliability will be assessed through video ratings by a second blinded assessor. In addition to these analyses, the clinical utility of the MuSICCA will be evaluated using a questionnaire to be completed by clinicians and relatives of the participants following the completion of the MuSICCA assessment. Ethics and dissemination Ethical approval has been obtained for this study from the Research Ethics Committee and Health Research Authority of the National Health Service of the UK (ID: 167534). Results will be presented at national and international conferences, published in scientific journals and disseminated to participant representatives, clinicians, educators and care providers.

description: Abstract: The teaching and implementation of Business Ethics remain a challenge for academics and practitioners for three main reasons: the complexity of the factors influencing decision-making processes; the prevalence of business and behavioral models that do not encourage ethics; and the lack of easy-to-apply pedagogical models with theoretical rigor. The aim of this study is to provide a conceptual framework and a guide for decision-making to face ethical conflicts in business. To this end, we carried out an empirical qualitative analysis through the methodology of Grounded Theory, based on 14 semi-structured interviews with experienced people in different business fields. The main contribution of this work consists of providing a simple model of decision-making, combining both an orientation towards the active promotion of ethical behavior and theoretical rigor, confirmed by the consistency with other previous studies present in the specialized literature.

description: The meridional circulation plays an essential role in determining the basic mechanism of the dynamo action in case the of a low eddy diffusivity. Flux-transport dynamos with strong return flow and a deep stagnation point are discussed in the case of a positive $α$-effect located in the overshoot layer and a rotation law consistent with helioseismology. By means of a linear dynamo model, it will be shown that the migration of the toroidal belts at lower latitudes and the periods of the activity cycles are consistent with the observations. Moreover, at variance with previous investigations, the typical critical dynamo numbers of dipolar solutions are significantly smaller that those of quadrupolar solutions even in the regime of strong flow.

description: The effect of NiO nanoparticle size was studied to understand its impact on adsorption and catalytic activity during oil recovery and upgrading. A series of different-sized NiO nanoparticles between 5 and 80 nm were prepared. XRD, BET, FTIR, HRTEM and TGA were used to characterize the nanosize effect on the textural properties, shape and morphology. Quinolin-65 (Q-65) was first used as an asphaltene model molecule. Langmuir and Freundlich adsorption isotherms models and computational modeling for the interaction between NiO nanoparticle surface and Q-65 were carried out to understand the adsorption behavior. TGA/DTA and TGA-MS techniques were used to study the effect of NiO nanosizes on catalytic thermo-oxidative decomposition of the adsorbed Q-65. The entire study was repeated using visbroken residue n-C5 asphaltenes. For both Q-65 and n-C5 asphaltene post-adsorption oxidation, the Kissinger-Akahira-Sunose (KAS) kinetic method was used to estimate the kinetic triplets, namely f (α), Eα and Aα.

description: We explore the ability of directional nuclear-recoil detectors to constrain the local velocity distribution of weakly interacting massive particle (WIMP) dark matter by performing Bayesian parameter estimation on simulated recoil-event data sets. We discuss in detail how directional information, when combined with measurements of the recoil-energy spectrum, helps break degeneracies in the velocity-distribution parameters. We also consider the possibility that velocity structures such as cold tidal streams or a dark disk may also be present in addition to the Galactic halo. Assuming a carbon-tetrafluoride detector with a 30-kg-yr exposure, a 50-GeV WIMP mass, and a WIMP-nucleon spin-dependent cross-section of 0.001 pb, we show that the properties of a cold tidal stream may be well constrained. However, measurement of the parameters of a dark-disk component with a low lag speed of ~50 km/s may be challenging unless energy thresholds are improved.

Behavioral vs. Neural Methods in the Treatment of Acutely Comatose Patients
Creators: name: Noh, Hyungrae
Publisher: name: Ramon Llull Journal of Applied Ethics
Year: 2022

description: Abstract: Behaviorally assessing residual consciousness of acutely comatose patients involves a high rate of false-negatives. That is, long-term behavioral assessment shows that 41% of vegetative state patients in fact have residual consciousness. Nonetheless, surrogates need to remove ventilation before the acute-phase passes away if they want to induce medico-legal death due to pragmatic factors, such as financial costs. So, surrogate decision-making regarding behaviorally nonresponsive acutely comatose patients involves a moral dilemma: should we ignore the chance that patients have residual consciousness for the sake of pragmatic factors? This paper examines whether neural methods can resolve the moral dilemma. Neural methods are used to assess residual consciousness of behaviorally nonresponsive postcomatose patients. For instance, by instructing a vegetative state patient to imagine wiggling all of her toes, consciousness is ascribed if brain activities are localized in the supplementary motor area. Since the most extensive application of neural methods has been inchronic population, it is unclear whether such methods can resolve the moral dilemma. I argue that neural methods also involve a high rate of false-negatives because current tasks of neural methods are structurally misguided. Given the argument, there is no significant difference between behavioral and neural methods regarding the moral dilemma.

description: Background: Examiner training is considered the most effective method to minimize psychometric errors in measurement for performance-based assessments. Purpose: To assess the effect of frame-of-reference training on the perceptions and scoring of examiners rating videotaped OSCE performances. Methods: Post-graduate medical trainees participated in a simulation-based OSCE designed to evaluate cardiac physical examination competence. Scores of these performances by a cohort of examiners trained in the frame-of-reference technique were compared to an untrained group. Examiner perceptions of the training and scoring process were assessed. Results: No significant differences were found in the mean scores and the internal consistency of the scoring tool between examiner cohorts. Examiners felt that training was potentially useful, although refinement of the frame-of-reference technique may have been required. Conclusion: Additional studies are needed to determine if examiner training is effective and to identify how this might be most effectively delivered.

description: © 2020 by the authors. Licensee MDPI, Basel, Switzerland. Doxorubicin (doxo) is an effective anticancer compound in several tumor types. However, as a consequence of oxidative stress induction and ROS overproduction, its high cardiotoxicity demands urgent attention. Vanillin possesses antioxidant, antiproliferative, antidepressant and anti-glycating properties. Therefore, we investigated the potential vanillin protective effects against doxo-induced cardiotoxicity in H9c2 cells. Using multiparametric approach, we demonstrated that vanillin restored both cell viability and damage in response to doxo exposure. Contextually, vanillin decreased sub-G1 appearance and caspase-3 and PARP1 activation, reducing the doxo-related apoptosis induction. From a mechanistic point of view, vanillin hindered doxo-induced ROS accumulation and impaired the ERK phosphorylation. Notably, besides the cardioprotective effects, vanillin did not counteract the doxo effectiveness in osteosarcoma cells. Taken together, our results suggest that vanillin ameliorates doxo-induced toxicity in H9c2 cells, opening new avenues for developing alternative therapeutic approaches to prevent the anthracycline-related cardiotoxicity and to improve the long-term outcome of antineoplastic treatment.

description: Abstract: Bioethics reflect on the new paradigm healthcare professionals face on their daily practice. This new paradigm professionals face is constantly creating new dilemmas, while also giving us tools to face the ones that had been raised in the past. Bioethics deals with constantly rethinking bioethical issues generated when new situations appear, and also constantly rethinks issues from the past that require an updated response. This shift to a new paradigm also worries the citizenship. The daily life of many people is impacted by these new and old dilemmas and they raise questions on them that require answers. There is little scientific production regarding the bioethical interests which concern professionals, especially touching on the alignment of social interest with the professionals who work in these issues. There is some production regarding the knowledge and training that first-year residents or students have. The objective of this work is to assess the interests of professionals in Bioethics and contrast them with the interests in Bioethics manifested by the civil society. We appreciate that there is a misalignment regarding the bioethical resources offered to professionals, their interests, and the interests that are socially appreciated in this field.

description: © 2020, eLife Sciences Publications Ltd. All rights reserved. One key bottleneck in understanding the human genome is the relative under-characterization of 90% of protein coding regions. We report a collection of 1,200 transgenic zebrafish strains made with the gene-break transposon (GBT) protein trap to simultaneously report and reversibly knockdown the tagged genes. Protein trap-associated mRFP expression shows previously undocumented expression of 35% and 90% of cloned genes at 2 and 4 days post-fertilization, respectively. Further, investigated alleles regularly show 99% gene-specific mRNA knockdown. Homozygous GBT animals in ryr1b, fras1, tnnt2a, edar and hmcn1 phenocopied established mutants. 204 cloned lines trapped diverse proteins, including 64 orthologs of human disease-associated genes with 40 as potential new disease models. Severely reduced skeletal muscle Ca2+ transients in GBT ryr1b homozygous animals validated the ability to explore molecular mechanisms of genetic diseases. This GBT system facilitates novel functional genome annotation towards understanding cellular and molecular underpinnings of vertebrate biology and human disease.

description: The quantitative study of the physical properties and chemical abundances of large samples of massive blue stars at different metallicities is a powerful tool to understand the nature and evolution of these objects. Their analysis beyond the Milky Way is challenging, nonetheless it is doable and the best way to investigate their behavior in different environments. Fulfilling this task in an objective way requires the implementation of automatic analysis techniques that can perform the analyses systematically, minimizing at the same time any possible bias. As part of the ARAUCARIA project we carry out the first quantitative spectroscopic analysis of a sample of 12 B-type supergiants in the galaxy NGC55 at 1.94 Mpc away. By applying the methodology developed in this work, we derive their stellar parameters, chemical abundances and provide a characterization of the present-day metallicity of their host galaxy. Based on the characteristics of the stellar atmosphere/line formation code FASTWIND, we designed and created a grid of models for the analysis of massive blue supergiant stars. Along with this new grid, we implemented a spectral analysis algorithm. Both tools were specially developed to perform fully consistent quantitative spectroscopic analyses of low spectral resolution of B-type supergiants in a fast and objective way. We present the main characteristics of our FASTWIND model grid and perform a number of tests to investigate the reliability of our methodology. The automatic tool is applied afterward to a sample of 12 B-type supergiant stars in NGC55, deriving the stellar parameters and abundances. The results indicate that our stars are part of a young population evolving towards a red supergiant phase. The derived chemical composition hints to an average metallicity similar to the one of the Large Magellanic Cloud, with no indication of a spatial trend across the galaxy.

description: Resource allocation trade-offs may occur between life-history traits in plants, including sexual reproduction and clonal growth. Pollination (fruit) failure may relax trade-offs, and excess resources stored in rhizomes may increase clonal growth. Two varieties of Cypripedium parviflorum, a rewardless orchid, responded to pollination success or failure with resource allocation (within ramets) and translocation (between ramets) appropriate to their respective life histories. Ramets financed their own fruits and had greater rhizome allocation in response to pollination failure. Var. makasin had low fruit set (~19.1%), prioritized fruit production, and translocated resources to sister ramets developing fruits (ramet and genet trade-offs). Var. pubescens had high fruit set (~45.1%), allocated more resources to leaves, which gained mass when developing fruits, and did not translocate resources (mitigated ramet trade-offs and no genet trade-offs). Clonality declined with increasing fruit set when fruit set was poor (i.e., var. makasin) and in low-density and large populations.

description: © 2020 National Academy of Sciences. All rights reserved. Data analyses typically rely upon assumptions about the missingness mechanisms that lead to observed versus missing data, assumptions that are typically unassessable. We explore an approach where the joint distribution of observed data and missing data are specified in a nonstandard way. In this formulation, which traces back to a representation of the joint distribution of the data and missingness mechanism, apparently first proposed by J. W. Tukey, the modeling assumptions about the distributions are either assessable or are designed to allow relatively easy incorporation of substantive knowledge about the problem at hand, thereby offering a possibly realistic portrayal of the data, both observed and missing. We develop Tukey's representation for exponential-family models, propose a computationally tractable approach to inference in this class of models, and offer some general theoretical comments. We then illustrate the utility of this approach with an example in systems biology.
