AN EARLY ENTERAL FEEDING PROTOCOL AFTER PERCUTANEOUS ENDOSCOPIC GASTROSTOMY TUBE PLACEMENT
Creators: name: Mungcal, Jeanie
Publisher: name: Zenodo
Year: 2020

description: A quality improvement (QI) project was planned to develop, pilot, and evaluate an evidence-based early enteral feeding protocol (EEFP) for patients with head and neck cancer who undergo PEG tube placements in a comprehensive cancer center in California. The purpose of the QI project was to decrease the time between PEG insertion and initiation of tube feeding. The QI project was planned to take place in a 6-bed subsection of the recovery room where patients were routinely kept overnight for monitoring after insertion of PEG tubes by Interventional Radiology. The iPARIHS framework was selected to guide the planning, implementation, and evaluation of this project. Addressing the three major constructs of the framework, innovation, recipients, and context facilitated the identification of required actions and consideration of potential barriers that may interfere with the implementation of this QI. Overall, the review of literature supported the early initiation of enteral feeding (EEF). The literature review also revealed that potential complications of EEF are a key element to consider in assessing the success of implementation. Based on the literature, and evidence-based EEFP was developed, a pilot plan was established, and an evaluation plan of the safety and feasibility of the EEFP was created including plan for patient education and follow up. After achieving the multidisciplinary team consensus, a clear procedure and a workflow chart were developed to guide the implementation of EEFP and clarify the roles of the members of the multidisciplinary team (Interventional radiologists, IR coordinator, dietician, registered nurses, and nurse practitioners). iv To evaluate whether the EEFP was successful, safe and feasible, three measures were established with the plan to assess these measures prior to the initiation pf project and after one month of implementation. The measures included: Length of time-in hoursbetween insertion of a PEG tune and initiation of tube feeding, the frequency and severity of complications associated with EEFP as assessed on the SIR classification system, and feeding tolerance. A plan for statistical comparison of average time to initiate feeding, rate of complications and incidence of feeding intolerance before and after initiation of EEFP was created along with diagrams and charts to display data and facilitate comparison.

description: Online malware scanners are one of the best weapons in the arsenal of cybersecurity companies and researchers. A fundamental part of such systems is the sandbox that provides an instrumented and isolated environment (virtualized or emulated) for any user to upload and run unknown artifacts and identify potentially malicious behaviors. The provided API and the wealth of information inthe reports produced by these services have also helped attackers test the efficacy of numerous techniques to make malware hard to detect.The most common technique used by malware for evading the analysis system is to monitor the execution environment, detect the presence of any debugging artifacts, and hide its malicious behavior if needed. This is usually achieved by looking for signals suggesting that the execution environment does not belong to a the native machine, such as specific memory patterns or behavioral traits of certain CPU instructions. In this paper, we show how an attacker can evade detection on such online services by incorporating a Proof-of-Work (PoW) algorithm into a malware sample. Specifically, we leverage the asymptotic behavior of the computational cost of PoW algorithms when they run on some classes of hardware platforms to effectively detect a non bare-metal environment of the malware sandbox analyzer. To prove the validity of this intuition, we design and implement the POW-HOW framework, a tool to automatically implement sandbox detection strategies and embed a test evasion program into an arbitrary malware sample. Our empirical evaluation shows that the proposed evasion technique is durable, hard to fingerprint, and reduces existing malware detection rate by a factor of 10. Moreover, we show how bare-metal environments cannot scale with actual malware submissions rates for consumer services.

description: The fundamental excitations in superconductors - Bogoliubov quasiparticles - can be either a resource or a liability in superconducting devices: they are what enables photon detection in microwave kinetic inductance detectors, but they are a source of errors in qubits and electron pumps. To improve operation of the latter devices, ways to mitigate quasiparticle effects have been devised; in particular, combining different materials quasiparticles can be trapped where they do no harm and their generation can be impeded. We review recent developments in these mitigation efforts and discuss open questions.

description: We study the Kitaev-Heisenberg-$Γ$ model with antiferromagnetic Kitaev exchanges in the strong anisotropic (toric code) limit to understand the phases and the intervening phase transitions between the gapped $Z_2$ quantum spin liquid and the spin-ordered (in the Heisenberg limit) as well as paramagnetic phases (in the pseudo-dipolar, $Γ$, limit). We find that the paramagnetic phase obtained in the large $Γ$ limit has no topological entanglement entropy and is proximate to a gapless critical point of a system described by an equal superposition of differently oriented stacked one-dimensional $Z_2\times Z_2$ symmetry protected topological phases. Using a combination of exact diagonalization calculations and field-theoretic analysis we map out the phases and phase transitions to reveal the complete phase diagram as a function of the Heisenberg, the Kitaev, and the pseudo-dipolar interactions. Our work shows a rich plethora of unconventional phases and phase transitions and provides a comprehensive understanding of the physics of anisotropic Kitaev-Heisenberg-$Γ$ systems along with our recent paper [Phys. Rev. B 102, 235124 (2020)] where the ferromagnetic Kitaev exchange was studied.

description: The Weak Gravity Conjecture has recently been re-formulated in terms of a particle with non-negative self-binding energy. Because of the dual conformal field theory (CFT) formulation in the anti-de Sitter space the conformal dimension $Δ(Q)$ of the lowest-dimension operator with charge Q under some global U(1) symmetry must be a convex function of Q. This property has been conjectured to hold for any (unitary) conformal field theory and generalized to larger global symmetry groups. Here we refine and further test the convex charge conjecture via semiclassical computations for fixed charge sectors of different theories in different dimensions. We analyze the convexity properties of the leading and next-to-leading order terms stemming from the semiclassical computation, de facto, extending previous tests beyond the leading perturbative contributions and to arbitrary charges. In particular, the leading contribution is sufficient to test convexity in the semiclassical computations. We also consider intriguing cases in which the models feature a transition from real to complex conformal dimensions either as a function of the charge or number of matter fields. As a relevant example of the first kind, we investigate the $O(N)$ model in $4+ε$ dimensions. As an example of the second type we consider the $U(N)\times U(M)$ model in $4-ε$ dimensions. Both models display a rich dynamics where, by changing the number of matter fields and/or charge, one can achieve dramatically different physical regimes. We discover that whenever a complex conformal dimension appears, the real part satisfies the convexity property.

description: High quality single crystals of a ferromagnetic superconductor URhGe were successfully grown. The electrical resistivity was measured for the field along b-axis in the orthorhombic crystal structure in order to study precisely its field re-entrant superconductivity which occurs in the vicinity of the field $H_{\rm R}$, where the easy magnetization switches from $c$ to b-axis. The field re-entrant superconductivity of URhGe is analyzed with special focus on its dependence with the value of residual resistivity $ρ_0$ and the coefficient $A$ of $T^2$ term of the resistivity. The experimental results are well explained by a crude model related with the field dependence of the effective mass $m^\ast$, where the corresponding critical temperature $T_{\mathrm{sc}}(m^\ast)$ and the upper critical field $H_{\rm c2}$ are strongly enhanced. Discussion is made on the interplay between magnetic and superconducting phase diagram as well as the link between $T_{\mathrm{sc}}$ and $A$ in other heavy fermion superconductors.

description: The zero-range process is a stochastic interacting particle system that is known to exhibit a condensation transition. We present a detailed analysis of this transition in the presence of quenched disorder in the particle interactions. Using rigorous probabilistic arguments we show that disorder changes the critical exponent in the interaction strength below which a condensation transition may occur. The local critical densities may exhibit large fluctuations and their distribution shows an interesting crossover from exponential to algebraic behaviour.

description: Cerebral palsy (CP) is the most common disability in children caused by central nervous system lesion. The aim of the present study was to verify the intensive neuromotor therapy effects in children with CP, in a reference Brazilian centre. In this study, three years of medical records from a Brazilian reference Centre of Intensive Neuromotor Therapy (INMT) which use the INMT protocol were analysed. The motor evaluation for each child was done by the Gross Motor Function Classification System (GMFCS) and GMFM-88 by an experienced professional, before and after each INMT module. A total of 53 children between the ages of 1 and 15 years (age at treatment initiation, initial evaluation), with a mean age of 5.94±3.38 years, participated in the study. Participants performed between 1 and 10 INMT modules. There was no strong correlation between age and overall performance on the GMFM scale, but it was observed a strong negative correlation between the percentage of GMFM gains and the number of modules (r=-0.709; R2 = 0.50; p = 0.022, CI95%[0.014 - 0.026]), suggesting that patients tend to present higher percentage gains in the first modules. Through an intra-module comparison, it was observed statistical difference in the total score in each of the modules.

The structure of the liquid-vapor interface
Creators: name: Rensink, Ronald Andy
Publisher: name: University of British Columbia
Year: 2010

description: This thesis presents a review of the theories currently being used to describe the structure of the liquid-vapor interface. The fluids considered are those consisting of "argon-like" molecules, which have radially symmetric potentials. "Wall effects" upon the interface are assumed to be negligible. The derivations of several theories have been recast into forms which depend upon a few common principles. The technique of functional differentiation is extensively used in this regard. This allows each theory to be identified with one of three different approaches: mean-field theory, integro-differential equations, or fluctuation theory. Good agreement is found between the results of theories within each class. The three approaches are shown to be different aspects of a single consistent model of the liquid-vapor interface.

description: We derive distance-dependent estimators for two-center and three-center electron repulsion integrals over a short-range Coulomb potential, $\textrm{erfc}(ωr_{12})/r_{12}$. These estimators are much tighter than one based on the Schwarz inequality and can be viewed as a complement to the distance-dependent estimators for four-center short-range Coulomb integrals and for two-center and three-center full Coulomb integrals previously reported. Because the short-range Coulomb potential is commonly used in solid-state calculations, including those with the HSE functional and with our recently introduced range-separated periodic Gaussian density fitting, we test our estimators on a diverse set of periodic systems using a wide range of the range-separation parameter $ω$. These tests demonstrate the robust tightness of our estimators, which are then used with integral screening to calculate periodic three-center short-range Coulomb integrals with linear scaling in system size.

description: O 3º Congresso Internacional de Atividade Física, Nutrição e Saúde proporcionou discussão, reflexão e prática acerca das bases teórico-metodológicas dirigidas às intervenções na área de Atividade Física, Nutrição e Saúde. Reflexões sobre o processo de envelhecimento, bem como os aspetos do envelhecer com saúde e qualidade de vida foram abordados no evento.


O envelhecimento é um fenômeno natural, universal, irreversível e não ocorre de forma simultânea e igualitária nos seres humanos. Envelhecer faz parte da vida e, visto a luz dos conhecimentos atuais, nada é possível para fazer alterar este processo. Atualmente, o envelhecimento constitui um dos temas de maior interesse da sociedade devido à transição epidemiológica que o mundo está apresentando. Diante disso, procurar respostas sobre quais são as mudanças que ocorrem nesse período, quais são as causas e as consequências são os desafios da ciência com o objetivo de retardar esse processo.


Para melhor compreensão da relação entre envelhecimento e saúde, uma abordagem multidimensional deve ser considerada, levando em consideração os aspectos biológicos, físicos, psicológicos, econômicos e sociais. Além disso, a qualidade de vida passa a ser um aspecto importante por atender as demandas de saúde da sociedade.


Tais discussões realizadas servirão para subsidiar uma análise crítica sobre a atuação dos profissionais da saúde, no Brasil e no Estado de Sergipe.  É inadiável, portanto, que os acadêmicos e os professores de todas as áreas do conhecimento, conscientizem-se de que é necessário atualização e capacitação constante.

description: While Case-based reasoning (CBR) has successfully been deployed on the Web, its data models are typically inconsistent with existing information infrastructure and standards. In this paper, we examine how CBR can operate on the emerging Web of Data, with mutual benefits. The expense of knowledge engineering and curating a case base can be reduced by using Linked Data from the Web of Data. While Linked Data provides experiential data from many different domains, it also contains inconsistencies, missing data and noise which provide challenges for logic-based reasoning. CBR is well suited to provide alternative and robust reasoning approaches. We introduce (i) a lightweight CBR vocabulary which is suited for the open ecosystem of the emerging Web of Data, and provide (ii) a detailed example of a case base using data from multiple sources. We propose that for the first time the Web of Data provides data and a real context for open CBR systems.

description: According to Hudson's theorem, any pure quantum state with a positive Wigner function is necessarily a Gaussian state. Here, we make a step towards the extension of this theorem to mixed quantum states by finding upper and lower bounds on the degree of non-Gaussianity of states with positive Wigner functions. The bounds are expressed in the form of parametric functions relating the degree of non-Gaussianity of a state, its purity, and the purity of the Gaussian state characterized by the same covariance matrix. Although our bounds are not tight, they permit us to visualize the set of states with positive Wigner functions.

IMPLEMENTATION OF CLINICAL PRACTICE GUIDELINES FOR HEPATITIS C INFECTION
Creators: name: Subedi, Gayatri
Publisher: name: Zenodo
Year: 2020

description: Hepatitis C Virus (HCV) is the most common chronic blood-borne liver infection affecting an estimated 3-5 million Americans annually. It is a leading cause of end-stage liver disease, hepatocellular carcinoma, and liver transplant. HCV is transmitted sexually, through needlestick injuries, needle sharing, mother-to-child transmission, blood transfusions, and during tattooing or piercings. The number of people with Acute HCV tripled between 2011-2016 due to an increase in IV drug use associated with the opioid epidemic. Timely screening and treatment of HCV infection can prevent disease transmissions, reducing the chances for liver diseases and its complications. Evidencebased practice (EBP) guidelines can help providers remain up-to-date with new recommendations leading them to manage and treat HCV effectively. The purpose of this DNP project was to develop, implement, and evaluate EBP guidelines for screening and treatment of patients at risk for HCV infection in an outpatient Gastroenterology clinic without an established clinical practice guideline. A tailored HCV screening and treatment protocol was developed, piloted, and evaluated at the clinical practice site by using the Plan Do Study Act (PDSA) cycle framework. Data was collected and trended biweekly for 12 weeks. The results were analyzed using the QI Macros. Overall, at the end of project implementation, the rates of HCV screening increased from an average of 50% to 71%, with the promise of an average of more than 80% beyond week 12. The PDSA model was effective in driving a new evidence-based practice changes in iv implementing new clinical practice guidelines, leading to increased screening, diagnostics, and treatment of HCV positive patients. Future recommendations for clinicians include focusing on staff, patient, and family education to raise awareness of HCV infection, assisting patients in navigating insurance and social resources, and encouraging patients to make a follow-up appointment who refuse HCV screening (patients with risk factors).

For these maps Bruin and Todd have shown the existence and uniqueness of equilibrium states for the potential $ϕ_t:x\mapsto-t\log|Df(x)|$, for $t$ close to 1. We show that these equilibrium states vary continuously in the weak$^*$ topology within such families. Moreover, in the case $t=1$, when the equilibrium states are absolutely continuous with respect to Lebesgue, we show that the densities vary continuously within these families.

description: Internet of Space Things (IoST) is a challenging paradigm, which is currently attracting great interest from the scientific and industrial communities. IoST is based on the integration of the space segment into the global Internet of Things (IoT) infrastructure. In the relevant literature, reference is generally made to multiple constellations of nanosatellite platforms, used to enable IoT services on a global scale, including also disadvantaged and poorly infrastructured areas. In this paper, we focus on multi-tenant IoT scenarios, wherein multiple CubeSats constellations are enabled to offer services by exploiting a dynamic federation model. The objective is to efficiently provide services in an IoST scenario by leveraging an effective cooperation strategy originally designed for terrestrial IoT networks, the Mobile-IoT-Federation-as-a-Service (MIFaaS) paradigm. We extend this vision to IoT satellite networks in order to allow a constellation of satellites to effectively execute tasks through a tight cooperative behaviour with other CubeSats constellations. The reported performance evaluation studies show that better performance, in terms of percentage of tasks successfully completed, can be achieved through the implementation of the proposed cooperation paradigm.

A Transversal and Integrative Analysis of Exercise: A Study with Physical Activity Practitioners
Creators: name: Morais, Rita

Publisher: name: Motricidade
Year: 2018

description: This study was done with individuals that practiced exercise and had two main objectives: (a) understand the importance of psychological factors in the process of adoption and maintenance of exercise behavior; and (b) analyze exercise behavior by assuming an integrative conceptual perspective of different factors involved in exercise, especially the ones related with the psychological domain. Fifteen participants (seven males and eight females) with different levels of experience in exercise were selected for this study (five at one month, five at six months and five with 12 or more months of exercise practice). The participants had a mean age of 37.3 years old. Data were collected based on the interview guide “Psychological Assessment in Exercise: Interview Guides for Practitioners and Instructors - Version for Practitioners”. The main results showed that the exercise was explained by individual factors (e.g., psychological), contextual factors (e.g., local of practice), and cultural factors (e.g., stereotypes) that, in turn, changed across the time of exercise practice of participants. In conclusion, the use of a qualitative perspective that integrates different conceptual approaches proved to be crucial to understand the factors involved in exercise behavior.

description: Observations of the star EPIC 220208795 (2MASS J01105556+0018507) reveal a single, deep and asymmetric eclipse, which we hypothesize is due to an eclipsing companion surrounded by a tilted and inclined opaque disk, similar to those seen around V928 Tau and EPIC 204376071. We aim to derive physical parameters of the disk and orbital parameters for the companion around the primary star. The modeling is carried out using a modified version of the python package pyPplusS, and optimization is done using emcee. The period analysis makes use of photometry from ground-based surveys, where we perform a period folding search for other possible eclipses by the disk. Parameters obtained by the best model fits are used to obtain the parameter space of the orbital parameters, while the most likely period obtained is used to constrain these parameters. The best model has an opaque disk with a radius of $1.14\pm0.03$ $R_{\odot}$, an impact parameter of $0.61\pm0.02$ $R_{\odot}$, an inclination of $77.01^{\circ}\pm0.03^{\circ}$, a tilt of $36.81^{\circ}\pm0.05^{\circ}$ and a transverse velocity of $77.45\pm0.05$ km s$^{-1}$. The two most likely periods are $\sim 290$ days and $\sim 236$ days, corresponding to an eccentricity of $\sim 0.7$, allowing us to make predictions for the epochs of the next eclipses. All models with tilted and inclined disks result in a minimum derived eccentricity of 0.3, which in combination with the two other known small transiting disk candidates V928 Tau and EPIC 204376071, suggest that there may be a common origin for their eccentric orbits.

description: We study a class of DFSZ-like models for the QCD axion that can address observed anomalies in stellar cooling. Stringent constraints from SN1987A and neutron stars are avoided by suppressed couplings to nucleons, while axion couplings to electrons and photons are sizable. All axion couplings depend on few parameters that also control the extended Higgs sector, in particular lepton flavor-violating couplings of the Standard Model-like Higgs boson $h$. This allows us to correlate axion and Higgs phenomenology, and we find that that ${\rm BR}(h \to τe)$ can be as large as the current experimental bound of 0.22%, while ${\rm BR} (h \to μμ)$ can be larger than in the Standard Model by up to 70%. Large parts of the parameter space will be tested by the next generation of axion helioscopes such as the IAXO experiment.

description: This Phase 2 Research Report of the City of Parramatta "Cultural Infrastructure and Investment Strategy 2039" articulates the opportunities and needs for arts and cultural infrastructure beyond the immediate CBD and North Parramatta. Its decision making principles are the same as those for Phase 1, being based on the need to address the City’s expressed desire to embrace all types of cultural activity and space within its classification framework, and to encompass all the creative value chain dimensions according to its internationally-informed model of the cultural cycle (see elaboration of the framework and model below). The rationale for its priority framework is consistent with Phase 1’s aim of turning Parramatta into “a dynamic regional cultural hub, successfully catering and sensitive to the diverse cultural needs and interests of residents, workers, visitors and people from the Greater Western Sydney region” (p. 14). It is founded on the requirement to realise this aim imaginatively, equitably and sustainably, capitalising on Parramatta LGA’s growth while securing its future as a major urban centre that attracts and retains a substantial creative workforce making a significant contribution to the local cultural economy.

description: Photogrammetry is a relatively simple and objective instrument of evaluation that provides accurate and reproducible quantitative results, if applied rigorously, existing nowadays several protocols. The main purpose was to systematically review the utilized feet positioning to conduct a semi-static postural evaluation through photogrammetry. It was performed a systematic review of observational studies and clinic trials using the keywords “photogrammetry” and “spinal postural evaluation” to conduct searches on scientific databases. The eligibility criteria adopted were: utilize the photogrammetry to evaluate children, teenagers, adults or elders with or without pathologies; explicit the utilized feet positioning to conduct the evaluation; and be written in English, Portuguese or Spanish. The methodological quality was assessed by Downs and Black scale and the strength of evidence by the best evidence synthesis. It was found 1.786 articles and 40 were included in this review. The main feet positioning found were: self-referred, separated and in parallel, united and in parallel and standard self-referred. The review exhibited strong strength of evidence in the methodological quality assessment. Considering the main feet positioning found, it is considered primordial that the selection of evaluation methodology respects the specific instructions of each analysis protocol or software.

title: EUREEKA: Deepening the Semantic Web by More Efficient Emergent Knowledge Representation and Processing
Creators: name: Nováček, Vít
Publisher: name: CEUR-WS

Subjects: subject: Knowledge management
subject: Semantic web

description: One of the major Semantic Web challenges is the knowledge acquisition bottleneck. New content on the web is produced much faster than the respective machine readable annotations, while a scalable knowledge extraction from the legacy resources is still largely an open problem. This poster presents an ongoing research on an empirical knowledge representation and reasoning framework, which is tailored to robust and meaningful processing of emergent, automatically learned ontologies. According to the preliminary results of our EUREEKA1 prototype, the proposed framework can substantially improve the applicability of the rather messy emergent knowledge and thus facilitate the knowledge acquisition in an unprecedented way.
IMPROVING ADHERENCE TO BRAIN TRAUMA FOUNDATION GUIDELINES ON INTRACRANIAL PRESSURE MONITORING AND CEREBROSPINAL FLUID DRAINAGE

description: Traumatic brain injury is the third leading cause of injury-related deaths. Although the Brain Trauma Foundation (BTF) established guidelines in 1995, adherence to these practice recommendations has not been consistent. ICP monitoring and CSF drainage are two of these guidelines that are explored in this quality improvement project. The purpose of this DNP project was to increase adherence to the BTF guidelines for ICP monitoring and cerebrospinal fluid (CSF) drainage during the first 24 hours after external ventricular drain (EVD) placement in adult patients with severe TBI (sTBI). The objectives of this project were to (a) describe baseline adherence rates to the BTF guidelines for ICP monitoring and CSF drainage, (b) implement the SIBICC algorithm and a CSF drainage protocol, (c) develop and implement an educational program regarding the SIBICC algorithm and the CSF drainage protocol, (d) evaluate adherence rates to the BTF guidelines for ICP monitoring and CSF drainage after implementation, (e) increase knowledge related to BTF guidelines on ICP monitoring and CSF drainage, and (f) increase self-efficacy (confidence) on ICP monitoring and CSF drainage. The Plan-Do-Study-Act was the conceptual framework used to support this quality improvement project. Due to the COVID-19 pandemic, implementation was suspended until normal hospital operations are resumed. Data from a convenience sample of six sTBI patients meeting inclusion criteria and exclusion criteria during pre-implementation were collected. The average iv completeness of documentation for ICP monitoring and CSF drainage was 83% and 65.3% respectively. Adherence rates for ICP monitoring were 33% and 0% for CSF drainage. Nurses’ knowledge scores of ICP monitoring and CSF drainage increased after education (from an average of 55.6% pre-test to 80% post-test, with a 26.6 percentage point improvement). Nurses’ self-efficacy for ICP monitoring and CSF drainage also improved (from 12% to 17% for the highly confident item for ICP monitoring, and from 7% to 20% highly confident for CSF drainage). Although an improvement in adherence rate was not determined within the project timeframe, analysis of baseline data revealed areas for improvement. Variation in practice was shown to exist on ICP monitoring and CSF drainage and is expected to be reduced and eventually replaced by evidence-based guidelines with the future implementation of the SIBICC algorithm and the CSF drainage protocol.
Emerging mechanisms of magnetocaloric effect in phase-separated metals

description: We present a study of the magnetocaloric effect in metallic systems exhibiting first-order magnetic transitions and focus on consequences of magnetic phase separation. We account for ferrimagnetic, ferromagnetic, and Neel antiferromagnetic order. Based on the archetypal Hubbard model being treated within the mean-field approximation, we provide and explore its implications on the field-induced entropy change in metallic system with phase separation. Chosen framework allows us to properly analyze phase volumes' dependence on parameters of phase-separated (PS) system. Moreover, an account for phase separation boundaries as functions of magnetic field provides a natural splitting of the PS region, where each subregion corresponds to a different temperature dependence of entropy change: moving from one subregion to the other produces a kink, followed by a strong linear growth of entropy change. We encounter a second-order magnetic transition from paramagnetic to antiferromagnetic phase in PS region that occurs for particular parameter values. Despite the fact that both phases have zero total magnetization, the transition has a strong impact on entropy change.

description: MOTIVATION: Microarray technology makes it possible to measure thousands of variables and to compare their values under hundreds of conditions. Once microarray data are quantified, normalized and classified, the analysis phase is essentially a manual and subjective task based on visual inspection of classes in the light of the vast amount of information available. Currently, data interpretation clearly constitutes the bottleneck of such analyses and there is an obvious need for tools able to fill the gap between data processed with mathematical methods and existing biological knowledge. RESULTS: THEA (Tools for High-throughput Experiments Analysis) is an integrated information processing system allowing convenient handling of data. It allows to automatically annotate data issued from classification systems with selected biological information coming from a knowledge base and to either manually search and browse through these annotations or automatically generate meaningful generalizations according to statistical criteria (data mining). AVAILABILITY: The software is available on the website http://thea.unice.fr/
Laser enhancement of nuclear beta decay
Creators: name: Hebron, John Stephen
Publisher: name: University of British Columbia
Year: 2010

description: After deriving and discussing the solution to Dirac's equation for an electron in an external electromagnetic plane wave, the electron field operator is expanded in terms of this solution. The usual electron field operator in the four point theory of nuclear beta decay is replaced by this new field operator, and a formula is obtained for the new beta decay rate. This formula is found to agree with the formula stated by Becker et al. Arguments are presented which indicate that the decay rate will not be significantly enhanced. These arguments are supported by a quantum mechanical model consisting of a square well with barriers through which an electron in a quasi-stationary state tunnels, the rate of tunnelling being enhanced by an external linear electric field.

description: We present a comprehensive abundance analysis of 27 heavy elements in bright giant stars of the globular clusters M4 and M5 based on high resolution, high signal-to-noise ratio spectra obtained with the Magellan Clay Telescope. We confirm and expand upon previous results for these clusters by showing that (1) all elements heavier than, and including, Si have constant abundances within each cluster, (2) the elements from Ca to Ni have indistinguishable compositions in M4 and M5, (3) Si, Cu, Zn, and all s-process elements are approximately 0.3 dex overabundant in M4 relative to M5, and (4) the r-process elements Sm, Eu, Gd, and Th are slightly overabundant in M5 relative to M4. The cluster-to-cluster abundance differences for Cu and Zn are intriguing, especially in light of their uncertain nucleosynthetic origins. We confirm that stars other than Type Ia supernovae must produce significant amounts of Cu and Zn at or below the clusters' metallicities. If intermediate-mass AGB stars or massive stars are responsible for the Cu and Zn enhancements in M4, the similar [Rb/Zr] ratios and (preliminary) Mg isotope ratios in both clusters may be problematic for either scenario. For the elements from Ba to Hf, we assume that the s- and r-process contributions are scaled versions of the solar s- and r-process abundances. We quantify the relative fractions of s- and r-process material for each cluster and show that they provide an excellent fit to the observed abundances.
