description: We have conducted a new spectroscopic survey to characterize the nature of nuclear activity in Hickson Compact Groups (HCGs) galaxies and establish its frequency. We have obtained new intermediate resolution optical spectroscopy for 200 member-galaxies and corrected for underlying stellar population contamination using galaxy templates. Spectra for 11 additional galaxies have been acquired from the ESO and 6dF public archives and emission line ratios have been taken from the literature for 59 galaxies more. Here we present the results of our classification of the nuclear activity for 270 member-galaxies, which belong to a well defined sample of 64 HCGs. We found a large fraction of galaxies, 63%, with emission lines. Using standard diagnostic diagrams, 45% of the emission line galaxies were classified as pure AGNs, 23% as Transition Objects (TOs) and 32% as Star Forming Nuclei (SFNs). In the HCGs, the AGN activity appears as the most frequent activity type. Adopting the interpretation that in TOs a Low Luminosity AGN coexists with circumnuclear star formation, the fraction of galaxies with an AGN could rise to 42% of the whole sample. The low frequency (20%) of SFNs confirms that there is no star formation enhancement in HCGs. After extinction correction we found a median AGN H$α$ luminosity of 7.1$\times10^{39}$ erg s$^{-1}$, which implies that AGNs in HCG have a characteristically low luminosity. This result added to the fact, that there is an almost complete absence of Broad Line AGNs in Compact Groups (CGs) as found by Martinez et al.(2008a) and corroborated in this study for HCGs, is consistent with very few gas left in these galaxies. In general, therefore, what may characterize the level of activity in CGs is a severe deficiency of gas.

Vector bundles and sheaf-theoretic matrix-valued kernel functions
Creators: name: Peruzzi, Andrea
Publisher: name: Universität Paderborn
Year: 2022

description: In dieser Arbeit untersuchen wir das Zusammenspiel bestimmter dreifacher Massey-Produkte mit assoziativen rMatrizen und den sogenannten Szegö-Kernen. Im ersten Kapitel wiederholen wir die algebraisch-geometrische Theorie der as-soziativen Yang-Baxter-Gleichung, die diese Identität mit der Untersuchung von Vektorbündeln über Kurven des arithmetischen Geschlecht 1 in Beziehung setzt. Ausgehend von bestimmten Vektorbündeln auf der kubischen Weierstrass-Kurve, berechnen wir im zweiten Kapitel Lösungen der oben genannten Gleichung, die sogenannten assoziativen rMatrizen. Im dritten Kapitel stellen wir Szegö-Kerne vor, beweisen, dass sie schiefsymmetrisch sind, und zeigen, dass sie durch dreifache Massey-Produkte beschrieben werden können, die mit Vektorbündeln über Gorenstein-Kurven assoziiert sind. Darüber hinaus leiten wir zwei Identitäten ab, die solche Kernfunktionen erfüllen müssen, insbesondere sollte die Zweite als eine gar-bentheoretische Version der matrixwertigen Fay Identität betrachtet werden. Im letzten Teil dieser Arbeit wiederholen wir einige Ergebnisse bezüglich Linienbündeln über Riemannschen Flächen und Theta-Funktionen, um als besonderen Fallunserer Identität die trisekante Identität von Fay abzuleiten.
description: In this thesis we investigate the interplay of certain triple Massey products with associative rmatrices and the so called Szegö kernels. In the first chapter we recall the algebro-geometric theory of the associative Yang-Baxter equation which relates this identity to the study of vector bundles over curves of arithmetic genus one. In the second chapter, starting with certain vector bundles over Weierstrass cubic curve, we compute solutions, the so called associative rmatrices, of the afore mentioned equation. In chapter three we introduce Szegö kernels, we prove that they are skew-symmetric, and we show that they can be described through triple Massey products associated with vector bundles over Gorenstein curves. Moreover, we derive two identities which these kernel functions have to satisfy, in particular the second one should be considered as a sheaf-theoretic version of the matrix-valued Fay's identity. In the final part of this thesis we recall some results regarding line bundles over Riemann surfaces and theta functions in order to deduce, as a particular case of our identity, the Fay's trisecant identity.

description: The big bounce (BB) transition within a flat Friedmann-Robertson-Walker model is analyzed in the setting of loop geometry underlying the loop cosmology. We solve the constraint of the theory at the classical level to identify physical phase space and find the Lie algebra of the Dirac observables. We express energy density of matter and geometrical functions in terms of the observables. It is the modification of classical theory by the loop geometry that is responsible for BB. The classical energy scale specific to BB depends on a parameter that should be fixed either by cosmological data or determined theoretically at quantum level, otherwise the energy scale stays unknown.

description: We present an initial survey of Mg II absorption characteristics in the halos of a carefully constructed, volume-limited subsample of galaxies embedded in the spectroscopic part of the Sloan Digital Sky Survey. We observed quasars near sightlines to 20 low-redshift (z ~ 0.1), luminous M_r <= -20.5 galaxies in SDSS DR4 and DR6 with the LRIS-B spectrograph on the Keck I telescope. The primary systematic criteria for the targeted galaxies are a redshift z >~ 0.1 and the presence of an appropriate bright background quasar within a projected 75 kpc/h of its center, although we preferentially sample galaxies with lower impact parameters and slightly more star formation within this range. Of the observed systems, six exhibit strong [EW(2796) >= 0.3 Ang.] Mg II absorption at the galaxy's redshift, six systems have upper limits which preclude strong Mg II absorption, while the remaining observations rule out very strong [EW(2796) >= 1-2 Ang] absorption. The absorbers fall at higher impact parameters than many non-absorber sightlines, indicating a covering fraction f_c = 0.3-Angstrom absorbers at z ~ 0.1, even at impact parameters <= 35 kpc/h (f_c ~ 0.25). The data are consistent with a possible dependence of covering fraction and/or absorption halo size on the environment or star-forming properties of the central galaxy.

description: A purely electrical sensing scheme is presented that determines the concentration of macromolecules in solution by measuring the capacitance between planar microelectrodes. Concentrations of DNA in the ng/mL range have been used in samples of 1 microL volume. The method has been applied to the characterisation of the dielectrophoretic response of DNA without the need for any chemical modifications. The influence of electrical parameters like duty cycle, voltage and frequency has been investigated. The results are in good agreement with data from dielectrophoretic studies on fluorescently labelled DNA. Extension of the method down to the single molecule level appears feasible.

description: The class IIa histone deacetylases (HDACs) have pivotal roles in the development of different tissues. Of this family, Schwann cells express Hdac4, 5 and 7 but not Hdac9. Here we show that a transcription factor regulated genetic compensatory mechanism within this family of proteins, blocks negative regulators of myelination ensuring peripheral nerve developmental myelination and remyelination after injury. Thus, when Hdac4 and 5 are knocked-out from Schwann cells in mice, a JUN-dependent mechanism induces the compensatory overexpression of Hdac7 permitting, although with a delay, the formation of the myelin sheath. When Hdac4,5 and 7 are simultaneously removed, the Myocyte-specific enhancer-factor d (MEF2D) binds to the promoter and induces the de novo expression of Hdac9, and although several melanocytic lineage genes are misexpressed and Remak bundle structure is disrupted, myelination proceeds after a long delay. Thus, our data unveil a finely tuned compensatory mechanism within the class IIa Hdac family, coordinated by distinct transcription factors, that guarantees the ability of Schwann cells to myelinate during development and remyelinate after nerve injury.
Quantum transport through a graphene nanoribbon-superconductor junction

description: We study the electron transport through a graphene nanoribbon-superconductor junction. Both zigzag and armchair edge graphene nanoribbons are considered, and the effects of the magnetic field and disorder on the transport property are investigated. By using the tight-binding model and the non-equilibrium Green's function method, the expressions of the current, conductance, normal tunneling coefficient, and Andreev reflection coefficient are obtained. For a clean system and at zero magnetic field, the linear conductance increases approximatively in a linear fashion with the on-site energy. In the presence of a magnetic field and a moderate disorder, the linear conductance exhibits plateau structures for both armchair and zigzag edges. The plateau values increase with the width of the graphene ribbon. With a wide sample width, a saturated plateau value of $|ν|e^2/h$ emerges at the filling factor $ν$. For a small filling factor, the conductance can reach the saturated value at a small width, but for a high filling factor, it requires to have a quite wide sample width to reach the saturated value. In particular, the Andreev reflection coefficient is always at 0.5 after reaching the saturated value, independent of any system parameters. In addition, we also consider the finite bias case, in which the Andreev reflection coefficient and normal tunneling coefficient are studied.

description: The stability properties of simple element choices for the mixed formulation of the Laplacian are investigated numerically. The element choices studied use vector Lagrange elements, i.e., the space of continuous piecewise polynomial vector fields of degree at most r, for the vector variable, and the divergence of this space, which consists of discontinuous piecewise polynomials of one degree lower, for the scalar variable. For polynomial degrees r equal 2 or 3, this pair of spaces was found to be stable for all mesh families tested. In particular, it is stable on diagonal mesh families, in contrast to its behaviour for the Stokes equations. For degree r equal 1, stability holds for some meshes, but not for others. Additionally, convergence was observed precisely for the methods that were observed to be stable. However, it seems that optimal order L2 estimates for the vector variable, known to hold for r>3, do not hold for lower degrees.

Modeling the Disk (three-phase) Interstellar Medium

Subjects: subject: Astrophysics (astro-ph)

description: The evolution of galactic disks from their early stages is dominated by gasdynamical effects such as gas infall, galactic fountains, and galactic outflows, and further more. The influence of these processes is only understandable in the framework of diverse gas phases differing in their thermal energies, dynamics, and element abundances. To trace the temporal and chemical evolution of galactic disks, it is therefore essential to model the interstellar gasdynamics combined with stellar dynamics, the interactions between gas phases, and star-gas mass and energy exchanges as detailed as possible. This article reviews the potential of state-of-the-art numerical schemes like Smooth-Particle and grid-based hydrodynamics as well as the inherent processes as of star-formation criteria and feedback, energy deposit and metal enrichment by stars and on the influence of gas-phase interactions on the galactic gas dynamics and chemistry.

description: O banco de dados Brazilian Radiocarbon Database – BRC14Database tem como objetivo construir e disponibilizar para um amplo público, nacional e internacional, um banco de dados com todas as datações absolutas disponíveis atualmente para sítios arqueológicos no Brasil. Nos últimos anos tem sido crescente a construção de grandes bancos de dados em âmbito nacional e internacional com o objetivo de agregar um grande conjunto de informações que permita criar e estimular a realização de pesquisas em amplas escalas temporal e espacial. BRC14Database pretende contribuir para divulgação de um destes banco de dados, em construção no âmbito das pesquisas desenvolvidas no Laboratório de Estudos Interdisciplinares em Arqueologia da UFSC.

BRC14Database tem uma abrangência nacional, com sítios arqueológicos de todo o Brasil e uma abrangência temporal bastante extensa, contemplando uma cronologia de cerca de 40.000 anos, com datas desde o Pleistoceno Tardio até o Holoceno recente. Ao agrupar esse conjunto de informações pretendemos contribuir ao mesmo tempo para divulgação e valorização do patrimônio arqueológico brasileiro e das pesquisas arqueológicas realizadas no Brasil.A utilização de datações absolutas como indicadores de ocupação humana é uma prática corrente na arqueologia desde a segunda metade do século XX. Nas últimas décadas, a utilização de sequências de datações absolutas como indicadores de processos de longa duração, seja para inferir demografia e dinâmicas de povoamento ou para discutir interação entre mudanças paleoclimáticas e transformação cultural tem sido cada vez mais frequente.No Brasil a utilização de sequências de datações absolutas como proxys para discussões sobre demografia, processos de povoamento, transformação cultural e interações com dinâmicas ambientais permanece como um campo pouco explorado.

Além de oferecer uma consistente ferramenta de pesquisa e divulgação do patrimônio arqueológico brasileiro, a construção de BRC14Database se fundamenta na ideia de que a arqueologia apresenta um excelente caminho para abordar o tempo profundo, para estudar processos de transformação sócio-cultural na longa-duração e, no caso brasileiro, para fomentar a construção de histórias indígenas milenares, rompendo as barreiras colonialistas que impuseram uma divisão arbitrária entre história e pre-história e assim alijaram as populações indígenas de suas trajetórias históricas milenares, acarretando em silenciamentos e desterritorializações.A construção e manutenção de BRC14Database é um projeto que requer permanente atenção e atualização. Para que consigamos manter a base atualizada e em constante aprimoramento estimulamos fortemente a colaboração de todos.

New trends of wave energytechnologies attempt to explore new paths and intend to bring new answers to the problem of the competitiveness of the produced energy for conventional devices. This thesis provides the reader with mathematical models of wave-structure interactions applied to novel concepts of wave energy converters: a flexible piezoelectric wave energy harvester and a floater blanket wave energy converter. In chapter 1 I present an overview of the field of wave energy, a brief history and descriptions of working principles and technologies of wave energy conversion along with a number of classication schemes. Classical systems as well as new trends in the form of flexible or deformable converters and hybrid systems are presented. [Continues.]

description: We report spatially-resolved variations in the 3.4micron hydrocarbon absorption feature and the 3.3micron polycyclic aromatic hydrocarbon (PAH) emission band in the Circinus galaxy over the central few arcsec. The absorption is measured towards warm emitting dust associated with Coronal line regions to the east and west of the nucleus. There is an absorption optical depth tau(3.4um) ~0.1 in the core which decreases to the west and increases to the east. This is consistent with increased extinction out to ~40 pc east of the core, supported by the Coronal emission line intensities which are significantly lower to the east than the west. PAH emission is measured to be symmetrically distributed out to +/- 4 arcsec, outside the differential extinction region. The asymmetry in the 3.4micron absorption band reflects that seen in the 9.7micron silicate absorption band reported by Roche et al. (2006) and the ratio of the two absorption depths remains approximately constant across the central regions, with tau(3.4um) / tau(9.7um) ~ 0.06 +/-0.01. This indicates well-mixed hydrocarbon and silicate dust populations, with no evidence for significant changes near the nucleus.

title: Physically and Sexually Violent Juvenile Offenders: A Comparative Study of Victimization History Variables
Creators: name: Frazier, Monique R.
Publisher: name: Utah State University
Year: 1998

description: The primary purpose of this study was to examine and compare physically and sexually violent juvenile offenders (PVJOs and SVJOs) to determine whether specific factors in their abuse histories, if present, tend to be associated with-the type of violent offense pattern they exhibit. The Youth Experiences and Behaviors Structured Interview (YEBSI)--an instrument which assesses for primary (victimization), secondary (witnessing), and perpetrated abuse of an emotional, physical, and sexual nature, by and/or toward family members, acquaintances, strangers, and animals--was developed by the primary researcher for use in this study. Thirty-six PVJOs and 30 SVJOs were interviewed. Results indicated that the YEBSI demonstrated high levels of internal consistency reliability and a very high level of interrater reliability. Various descriptive statistical, scale, and subscale correlations for the YEBSI were provided.
Very high percentages of both groups reported experiencing and witnessing all types of abuse. In all cases, a similar or larger percentage of SVJOs reported histories of primary and secondary abuse. SVJOs reported more severe levels of emotional abuse, similar severity levels of physical abuse, and less extremely severe levels of sexual abuse than did PVJOs. Family members and acquaintances (as compared to strangers) tended to be far more frequently reported as perpetrators by respondents. Composite primary and secondary abuse scores were moderately correlated with abuse perpetration scores for SVJOs and strongly correlated with abuse perpetration scores for PVJOs. For emotional, family, acquaintance, and stranger abuse, reported primary-secondary abuse scores were found to be most highly correlated with abuse perpetration scores of the same nature (e.g., emotional abuse history-witness scores best correlated with physical abuse perpetration scores and family abuse history-witness scores best correlated with perpetration scores against family members) Finally, the classification variables correctly predicted 75% of those in the physically violent group and 67% of those in the sexually violent group, with an overall "hit" rate of 71%. Examination of the discriminant function-variable correlations in this study indicates that it was primarily the emotional, family-perpetrated, and sexual abuse subscales that defined the function. Theoretical interpretations and implications for these results are provided.

description: During the eighteenth and nineteenth centuries, at a time when the debate on theatre architecture was in full swing, Europe witnessed an unprecedented boom in the construction of performance spaces on the fringes of main theatres in metropoles: provincial theatres, secondary stages or theatres in private salons. This book examines spaces and components of these ‘minor’ theatres, not only in terms of architecture but also of their scenography. Through a wide range of case studies and rich iconographic material, this volume describes the solutions adopted in different cases, highlighting the challenges these theatres were facing and illustrating the dynamics between centres and provinces.

A study of the condensed phase in phosphorus doped silicon
Creators: name: Halliwell, Robin Ernest
Publisher: name: University of British Columbia
Year: 2011

description: Photoluminescent studies give evidence that a condensed phase of electrons and holes can be formed in silicon containing phosphorus donor concentrations from 9.0 x 10¹⁵ cm⁻³ to 4.3 x 10¹⁹ cm⁻³. When the impurity concentration is less than that required for derealization of the donor electrons, the condensed phase takes the form of electron-hole drops with carrier concentrations of 3.0 x 10¹⁸cm⁻³. For Impurity concentrations greater than that required for derealization of the donor electrons the experimental observations are interpreted as evidence for a condensed phase involving only holes. Heat treatment of silicon doped with phosphorus is found to produce marked changes in both the photoluminescence and the electron paramagnetic resonance for samples containing impurity concentrations 2.2 x 10¹⁸cm⁻³ ≤ N[sub D] ≤ 1.3 x 10¹⁹ cm⁻³. These changes are interpreted in terms of the production of neutral traps by residual impurities such as carbon and oxygen. The effect of this heat treatment on the photo-luminescence lends support to the hypothesis of a condensed hole phase for high impurity concentrations.

description: Permian Bryozoa from the glaciomarine Tasmania and southern Sydney Basins, Australia, and the cold to warm water Shan-Thai Terrane, southern Thailand, are studied following the taxonomic techniques of Morozova (1974), Snyder (1991) and Morozova and Lisitsyn (1996). Previously the fenestrate faunas of these regions have not been examined internally. This study will show that rigorous taxonomic methods, applied to all bryozoan groups, yields the information required for accurate biostratigraphic, palaeoecologic and biogeographic analysis.

description: Time-periodic light-field provides an emerging pathway for dynamically engineering quantum materials by forming hybrid states between photons and Bloch electrons. So far, experimental progress on light-field dressed states has been mainly focused on the occupied states, however, it is unclear if the transient photo-excited states above the Fermi energy $E_F$ can also be dressed, leaving the dynamical interplay between photo-excitation and light-field dressing elusive. Here, we provide direct experimental evidence for light-field dressing of the transient photo-excited surface states above $E_F$, which exhibits distinct dynamics with a delay response as compared to light-field dressed states below $E_F$. Our work reveals the dual roles of the pump pulse in both photo-excitation and light-field dressing, providing a more comprehensive picture with new insights on the light-induced manipulation of transient electronic states.
title: The Effect of Biofeedback Training on Marital Communication and Physiological Arousal
Creators: name: Nabers, Kent E.
Publisher: name: Utah State University
Year: 1998

description: It is well documented that the communication patterns of distressed couples are characterized by more negative and fewer positive behaviors. It has also been postulated that there is an association between physiological arousal and negative behaviors. According to this theory, as individuals become increasingly aroused, the number of negative behaviors also increases. This study explored the relationship between physiological arousal and marital communication. The three couples participating in the study received intensive biofeedback training with the hypothesis that an ability to control physiological arousal would result in improved marital communications. The Rapid Couples Interaction Scoring System was employed as a measurement of overt behavior, and physiological arousal was measured by electromyographic levels. The findings of this study suggest that, for some, biofeedback training is an effective intervention to improve marital communications.
title: An Evaluation Study of Site-Based Managed Behaviors in a Rural Utah School
Creators: name: Soriano, Barbara R. S.
Publisher: name: Utah State University
Year: 1998

description: Site-based management (SBM) in schools can trace its roots back to two phenomena, citizen's movements in large cities such as New York in the late 1960s and decentralization efforts of business in the 1970s. Both were done in the belief that achieving a better result can be done 11 through decisions made by the people closest to the process. Site-based management programs are diverse. Some stress one aspect, the restructuring of the school administration and program to affect achievement. Other schools stress a second aspect, the empowerment of teachers and stakeholders to make administrative decisions.
Whichever emphasis chosen, several changes must occur for school management to move from the central office to the local school. These changes are evolutionary, taking 10-15 years. An evaluation study in a northern rural Utah school that has been involved with site-based management since 1990 allows for a context to understand the changes that might occur, namely, (a) the relinquishment of central school district authority; (b) the assumption of authority by the local school; ( c) the assumption of accountability for student achievement; ( d) the development of sensitivity between school and community; and (e) the development of consensus among school stakeholders.
An instrument was developed for the evaluation, the Site-Based Management Progress Check. The instrument used items covering the agents and activities that would be present as these five changes occur. Additionally, the largest portion of the progress check was based on the goals in the school. As respondents showed more agreement concerning which goals were chosen and achieved, an inference was made that greater progress had occurred toward the team activity necessary for local school management. The data were provided by 100% of the lower-elementary teachers; upper-elementary teachers, however, were poorly represented, restricting data generalizability.
The study indicated that, despite its 7-year involvement with site-based management, the school was still at an early stage of development with no change in district authority and no use of stakeholder groups to monitor goals. The school did have a wide base of teacher leadership. Slow progress seems to be related to lack of knowledge of SBM processes.

Detection efficiency of plastic scintillators for elastically scattered positive pions
Creators: name: Felawka, Larry Thomas
Publisher: name: University of British Columbia
Year: 2011

description: The efficiency for detecting positive pions which have been scattered elastically from a target has been calculated for low pion energies. Measurements of the efficiency at pion kinetic energies 12 - 77 MeV were made for a 12" long x 5" diameter NE110 plastic scintillator optically coupled to a Philips XP1040 photomultiplier tube. The efficiencies varied from 94% at 12 MeV to 79% at 77 MeV.

description: We consider the $\mathrm{AdS}_3/\mathrm{CFT}_2$ description of Reissner-Nordstrøm black holes by studying their uplifted counterparts in five dimensions. Assuming a natural size of the extra dimension, the near horizon geometries for the extremal limit are exactly $\mathrm{AdS}_3 \times \mathrm{S}^2$. We compute the scattering amplitude of a scalar field, with a mode near threshold of frequency and extra dimensional momentum, by a near extremal uplifted black hole. The absorption cross section agrees with the two point function of the CFT dual to the scalar field.

description: An optical fiber magnetic field sensor based on lossy mode resonance (LMR) was designed. Furthermore, a hollow core-offset structure was designed to enhance the performance. Due to the destruction of the circular symmetry structure, the sensor has strong birefringence, resulting in x-polarization and y-polarization with two independent resonance valleys. The refractive index changes from 1.358 to 1.390 and a high sensitivity of 11,483.12 nm/RIU was obtained. In addition, the influence of structural parameters on the sensor was investigated. Magnetic field sensitivities of 893 pm/Gs and 754 pm/Gs were obtained theoretically. The feasibility of LMR is demonstrated for magnetic field measurements and a reference is provided for an optical fiber magnetic field.

description: We consider the problem of global in time existence and uniqueness of solutions of the 3-D infinite depth full water wave problem. We show that the nature of the nonlinearity of the water wave equation is essentially of cubic and higher orders. For any initial interface that is sufficiently small in its steepness and velocity, we show that there exists a unique smooth solution of the full water wave problem for all time, and the solution decays at the rate $1/t$.

description: Spiking neural networks (SNN) hold the promise of being a more biologically plausible, low-energy alternative to conventional artificial neural networks. Their time-variant nature makes them particularly suitable for processing time-resolved, sparse binary data. In this paper, we investigate the potential of leveraging SNNs for the detection of photon coincidences in positron emission tomography (PET) data. PET is a medical imaging technique based on injecting a patient with a radioactive tracer and detecting the emitted photons. One central post-processing task for inferring an image of the tracer distribution is the filtering of invalid hits occurring due to e.g. absorption or scattering processes. Our approach, coined PETNet, interprets the detector hits as a binary-valued spike train and learns to identify photon coincidence pairs in a supervised manner. We introduce a dedicated multi-objective loss function and demonstrate the effects of explicitly modeling the detector geometry on simulation data for two use-cases. Our results show that PETNet can outperform the state-of-the-art classical algorithm with a maximal coincidence detection $F_1$ of 95.2%. At the same time, PETNet is able to predict photon coincidences up to 36 times faster than the classical approach, highlighting the great potential of SNNs in particle physics applications.
Explaining the Early Exit of Eta Carinae from its 2009 X-Ray Minimum with the Accretion Model

description: We use the accretion model to explain the early exit of Eta Carinae from its 2009 X-ray minimum. In the accretion model the secondary star accretes mass from the primary wind near periastron passage, a process that suppresses the secondary wind. As the shocked secondary wind is responsible for most of the X-ray emission, the accretion process accounts for the X-ray minimum. The early exit from the 2009 X-ray minimum after four weeks, instead of ten weeks as in the two previous minima, is attributed to the primary wind that during the last minimum was somewhat faster and of lower mass loss rate than during the two previous X-ray minima. This results in a much lower mass accretion rate during the X-ray minimum. We show that using fluctuations in these quantities that are within the range deduced from fluctuations in the X-ray flux outside the minimum, can account for the short duration of the last X-ray minimum. The shorter X-ray minimum may have further implications on the recovery of the system from the spectroscopic event.

description: The increase in the use of plastics during the past few decades has caused environmental pollution due to the non-biodegradable and recalcitrance nature of the plastics. This has caused great problems for the solid waste management efforts. The development of biodegradable polymers from natural and renewable ingredients can address the challenges caused by plastic pollution. The present work deals with the optimization of the preparation process of sago starch-based biodegradable bioplastic films. The sago starch, glycerol-sorbitol mixture, and chitosan were used as polysaccharides, plasticizers, and antimicrobial agents, respectively. The factors screening and design optimization were performed using response surface methodology and Box-Behnken Design to investigate the interactions between all components in the film preparation. Furthermore, the developed bioplastic films were characterized through field emission scanning electron microscopy and Fourier transform infrared spectroscopy. The antimicrobial susceptibility assay showed the inhibition of the growth of Bacillus pumilus and Alcaligenes faecalis XF1 by incorporation of cinnamon essential oil into the film. Moreover, the developed films successfully reduced the proliferation of fungal growth on packaged bread samples. The microbial analysis found that the shelf life of the wheat bread was improved from 3 to 15 days. The sago starch bioplastic films developed in this study can potentially meet the requirements for food packaging films.

title: Are Bank Bailouts Welfare Improving?

description: "The financial sector bailouts seen during the Great Recession generated substantial opposition and controversy. We assess the welfare benefits of government-funded emergency support to the financial sector, taking into account its effects on risk-taking incentives.

In our quantitative general equilibrium model, the probability of a financial crisis depends on the balance sheet choices of financial intermediaries. Those choices are influenced by capital adequacy constraints and ex ante known emergency support provisions.

These policy tools interact to make financial sector bailouts welfare improving when capital adequacy constraints are consistent with current Basel III regulations. But these bailouts are potentially welfare decreasing when capital adequacy regulations are looser, as they were before the Great Recession."

description: "À l’époque de la Grande Récession, le renflouement public du secteur financier avait suscité une vive controverse. Nous évaluons les gains de bien-être associés aux aides publiques d’urgence à ce secteur, tout en tenant compte de leurs effets sur les incitations à la prise de risques.

Dans notre modèle d’équilibre général quantitatif, la probabilité d’une crise financière dépend des choix des intermédiaires financiers concernant la structure de leur bilan. Ces choix sont influencés par les contraintes que leur imposent les exigences de fonds propres réglementaires et par l’existence d’un mécanisme de soutien d’urgence connu ex ante.

En interagissant, ces instruments de politique publique font des sauvetages d’institutions financières par l’État un facteur d’amélioration du bien-être quand les exigences de fonds propres sont aussi contraignantes que les règles de Bâle III actuelles. Par contre, ces sauvetages peuvent entraîner une diminution du bien-être lorsque les exigences de fonds propres sont moins strictes, comme elles l’étaient avant la Grande Récession."
