description: We examine the conditions under which the solution of the radial stationary Schrödinger equation for the sextic anharmonic oscillator can be expanded in terms of Hermite functions. We find that this is possible for an infinite hierarchy of potentials discriminated by the parameter setting the strength of the centrifugal barrier. The $N$'th member of the hierarchy involves $N$ solutions for $N$ generally different values of the energy. For a particular member of the hierarchy, there exist infinitely many bound states with square integrable wave functions, written in terms of the Hermite functions, which vanish at the origin and at infinity. These bound states correspond to distinct values of the parameter setting the strength of the harmonic term. We also investigate connection with the polynomial solutions of the sextic oscillator obtained from the formalism of quasi-exactly solvable potentials.

description: Hardness and fracture toughness of Dy-123 single-domains were studied by Vickers micro-indentation. A significant anisotropy of the mechanical properties was observed. Hardness tests give higher values when performed in (001) planes rather than in planes parallel to the c-axis. Moreover cracks pattern around the indentation follows preferential orientation in planes parallel to the c-axis whereas a classical ''four-cracks'' pattern is observed in the (001) planes. It has been possible to show the crucial role played by the 211-particles in the deviating mechanism of cracks and the relevance of the 211-particle distribution high homogeneity in the material.

description: Modal and nonmodal analyses of fluid flows provide fundamental insight into the early stages of transition to turbulence. Eigenvalues of the dynamical generator govern temporal growth or decay of individual modes, while singular values of the frequency response operator quantify the amplification of disturbances for linearly stable flows. In this paper, we develop well-conditioned ultraspherical and spectral integration methods for frequency response analysis of channel flows of Newtonian and viscoelastic fluids. Even if a discretization method is well-conditioned, we demonstrate that calculations can be erroneous if singular values are computed as the eigenvalues of a cascade connection of the frequency response operator and its adjoint. To address this issue, we utilize a feedback interconnection of the frequency response operator with its adjoint to avoid computation of inverses and facilitate robust singular value decomposition. Specifically, in contrast to conventional spectral collocation methods, the proposed method (i) produces reliable results in channel flows of viscoelastic fluids at high Weissenberg numbers ($\sim 500$); and (ii) does not require a staggered grid for the equations in primitive variables.

description: In this paper we study a Darcy-scale mathematical model for biofilm formation in porous media. The pores in the core are divided into three phases: water, oil, and biofilm. The water and oil flow are modeled by an extended version of Darcy's law and the substrate is transported by diffusion and convection in the water phase. Initially there is biofilm on the pore walls. The biofilm consumes substrate for production of biomass and modifies the pore space which changes the rock permeability. The model includes detachment of biomass due to water flux and death of bacteria, and is implemented in MRST. We discuss the capability of the numerical simulator to capture results from laboratory experiments. We perform a novel sensitivity analysis based on sparse-grid interpolation and multi-wavelet expansion to identify the critical model parameters. Numerical experiments using diverse injection strategies are performed to study the impact of different porosity-permeability relations in a core saturated with water and oil.

This ethnography, utilizing corporeally-anchored community map-making and interview data with over 100 trans-spectrum persons, attends to how emerging disjunctures between law, policy and lived experience--as expressed through the regulation of bodies in space--impact and highlight structural inequalities across trans-spectrum identities and practices. Ultimately, this project shifts a static view of a singular homogenous trans community into a politically and socio-economically-anchored discussion of trans-spectrum experiences, cross cut by issues of class, race, and modalities of gender expression, all within the physical, social and political arenas of Washington, D.C.

In this regard, we first study the horizons of black holes in $f(R)$ gravity. The equation of motion and effective potential are also computed which eventually leads to possible existence of innermost circular orbits of accretion disc. We derive the specific energy, specific angular momentum and angular velocity of the particles moving in circular orbits also. A comparative study of various parameters are also presented. The locations of the event horizon, cosmological horizon, innermost and outermost stable circular orbits are also pointed out.

description: In the Aztec period and in colonial times different natural stones originating in the Valley of Mexico were used for building construction. Stone weathering was investigated onsite at various historical buildings within the old quarter of Mexico City. In this study, different aspects of weathering and deterioration at three significant historical buildings will be presented, the Aztec excavation site Templo Mayor, the Metropolitan Cathedral, and the colonial palace of the dukes of Heras Soto. Petrophysical properties of the main building stones of these structures were investigated like density, porosity, pore radii distribution, water uptake rate and coefficient, thermal and hygric expansion, and the mechanical properties of uniaxial compressive strength. A relationship between single critical property values, according to anisotropy fabric characteristics, and specific weathering forms could be deduced.
Explicitly broken lepton number at low energy in the Higgs triplet model

description: We suppose that lepton number is explicitly broken at low energy scale(M) in the framework of the Higgs triplet($Δ$) model. The scalar sector of the model is developed considering the particular assumption $M=v_Δ\approx$ eV. We show that such assumption infers a particular mass spectrum for the scalars that compose the triplet and cause a decoupling of these scalars from those that compose the standard scalar doublet.

description: The aim of this paper was to identify and analyze farmer’s strategies connected with diversification of their activities, associated with taking non-agricultural activities. There are four strategies implemented by farmers possessing small farms, which are associated with running non-agricultural activities. Studies have shown that the choice of a strategy for diversification is determined by various factors, and the chosen strategy of developing non-agricultural activities differentiates the workforce, the geographical extent of that activity and its economic importance as a source of family income. It also affects the farmer’s plans of farm production in the future.

description: Geochemical markers are being increasingly applied to fundamental questions in population and community ecology in marine habitats because they allow inferences on individuals dispersal, but vital effects, small sample size and instrumental limitation are still challenging particularly in deep-sea studies. Here we use shells of the deep-sea bivalve Idas modiolaeformis to assess potential effects of sample storage, mineralogy, and valve orientation on LA-ICPMS measurements. Trace element concentrations of (24)Mg, (43)Ca, (88)Sr, (137)Ba, (208)Pb, and (238)U are not affected by the two most commonly used storage methods of biologic deep-sea samples (frozen at -20°C and fixed in 95% ethanol); thus combined analysis of differently preserved specimens is possible when the number of individuals is insufficient and distinct sample fixation is needed for multiple purposes. Valve orientation had a strong impact on quantification of trace elements in the calcitic but not in the aragonitic layer of adult shells. Hence, to enable comparisons between adult shells and entirely aragonitic embryonic shells, a reference map of site-specific signatures can potentially be generated using the aragonitic layer of the adult shells. Understanding ontogenetic changes and environmental effects in trace element incorporation is critical before geochemical fingerprinting can be used as a tool for larval dispersal studies in the deep-sea.

Vegetation Greenness in Northeastern Brazil and Its Relation to ENSO Warm Events

Publisher: name: FID GEO

description: The spatio-temporal variability of trends in vegetation greenness in dryland areas is a well-documented phenomenon in remote sensing studies at global to regional scales. The underlying causes differ, however, and are often not well understood. Here, we analyzed the trends in vegetation greenness for a semi-arid area in northeastern Brazil (NEB) and examined the relationships between those dynamics and climate anomalies, namely the El Nino Southern Oscillation (ENSO) for the period 1982 to 2010, based on annual Normalized Difference Vegetation Index (NDVI) values from the latest version of the Global Inventory Modeling and Mapping Studies (GIMMS) NDVI dataset (NDVI3g) dataset. Against the ample assumption of ecological and socio-economic research, the results of our inter-annual trend analysis of NDVI and precipitation indicate large areas of significant greening in the observation period. The spatial extent and strength of greening is a function of the prevalent land-cover type or biome in the study area. The regression analysis of ENSO indicators and NDVI anomalies reveals a close relation of ENSO warm events and periods of reduced vegetation greenness, with a temporal lag of 12 months. The spatial patterns of this relation vary in space and time. Thus, not every ENSO warm event is reflected in negative NDVI anomalies. Xeric shrublands (Caatinga) are more sensitive to ENSO teleconnections than other biomes in the study area.

description: Given a nonlinear, univariate, bounded, and differentiable function $f(x)$, this article develops a sequence of Mixed Integer Linear Programming (MILP) and Linear Programming (LP) relaxations that converge to the graph of $f(x)$ and its convex hull, respectively. Theoretical convergence of the sequence of relaxations to the graph of the function and its convex hull is established. For nonlinear non-convex optimization problems, the relaxations presented in this article can be used to construct tight MILP and LP relaxations. These MILP and the LP relaxations can also be used with MILP-based and spatial branch-and-bound based global optimization algorithms, respectively.

TOWARD AN EGYPTIAN FRANCHISING LAW BASED ON A COMPARATIVE STUDY OF THE LAWS OF THE UNITED STATES, CHINA, AND MALAYSIA
Creators: name: Elsaman, Radwa Salah
Publisher: name: American University
Year: 2023

description: With the largest population in the Arab Middle East and serving as a midway point between Europe and East Asia at the center of the Middle East, Egypt offers one of the biggest sources of franchising markets in the world with new business opportunities. Egypt, however, does not have a specialized law regulating franchising which results in real challenges for investors seeking to franchise their businesses in Egypt, their legal advisors, and the courts deciding disputes arising from franchising transactions. The result of this lack of franchising laws in Egypt is that other laws have a substantial impact on franchising. Examples include contract, commercial, and agency laws. The outcome is that various laws and regulations apply to franchise transactions that contradict the very specific nature of franchising and make it difficult to negotiate and decide various issues arising from franchise agreements. Also, the application of such a variety of laws imposes heavy burdens on franchising parties. Time could not be better to discuss having a franchising law in Egypt. Legal reform is highly needed to recover from the economic impact of the January Revolution and to improve the chances for foreign investment. This dissertation examines franchising laws in countries that work as guidance to Egypt in establishing a new franchising law. The American franchise law was chosen as a representative example of the common law system, the Chinese franchise law as an example of the civil law system, and the Malaysian law as an example of the Islamic legal system. They will be compared and discussed in order to arrive at a proposed model for Egypt. This dissertation concludes that a comprehensive Egyptian franchise law proposal should address various issues that are usually dealt with through franchise laws around the globe such as disclosure commitments, registration requirements, and substantive rights and obligations of the parties. The model law recommended by the dissertation is a combination of the laws of the three examined legal systems. Being a civil law country should not prevent Egypt from following other franchising systems as long as those rules meet the Egyptian franchising legal market's requirements. Also, the fact that Islamic law is the main source of law in Egypt may not weigh so heavily when drafting a franchising law in Egypt as it turns out that Islamic law does not really affect franchise rules.

We prove a criterion for semisimplicity and analyze the square of the antipode S^2 of a semisimple weak Hopf algebra A. We explain how the Frobenius-Perron dimensions of irreducible A-modules and eigenvalues of S^2 can be computed using the inclusion matrix associated to A. A trace formula of Larson and Radford is extended to a relation between the global and Frobenius-Perron dimensions of A. Finally, an analogue of the Class Equation of Kac and Zhu is established and properties of $A$-module algebras and their dimensions are studied.

description: Im oberen Korallenoolith (Oxford-Kimmeridge) von Oker entwickelten sich kleine lagunäre Riffe, deren Gerüst aus Exogyren, Serpeln und großen einzelnen Korallenstöcken gebildet wurde. Die umgebende Fazies besteht aus stabilen Weichböden mit reicher Molluskenfauna (Nerineen, Lamellibranchiata). Gerüstbildende Algen werden nicht beobachtet. Dasycladaceen sind selten. In Zwickeln, Kleinhöhlen und leeren Exogyren-Schalen siedelte sich eine diverse Poriferen-Fauna an, die von tetractinelliden Demospongiae dominiert wird. Durch Umwandlung von Teilen des Schwammgewebes in Automikrit kam es zu einer in situ Erhaltung vieler Porifera-Skelette (bakterielle Ammonifikation). Neben diesen autigenen Mikritbildungen spielen weitere stromatolithische und thrombolithische Mikrobialithe bei der Stabilisierung der lagunären Patchreefs eine erhebliche Rolle.
description: In the uppermost facies of the OxfordianiKimmeridgian "Korallenoolith" of Oker small lagoonal patchreefs are present. They are constructed of exogyrid oysters, serpulids, and large single scleractinians. Framebuilding algae are absend. The surrounding sediments were stable soft bottoms with large numbers of nerineid gastropods and semi-infaunal bivales. Dasycladacean algae are rarely present. Within small caves, empty conches of exogyrids, and inter biogene spaces settled a large number of cryptic sponges (mainly tetractinellid demosponges). Caused by bacterial ammonification part of the sponge soft tissues were altered in automicrite. Therefore the sponge skeletons exhibit more or less their entire shapes. Beside this type of automicrite stromatolitic and and thrombolitic microbialites play an important role in stabilizing the patchreef frame.
On the social state of the E.U. : (the ethic of care, the open method of co-ordination, and the future of European social policy-making)
Creators: name: De Merich, Diego
Publisher: name: University of British Columbia
Year: 2011

description: The following study presents an analysis of historical and current trends within social policy development at the European level. Recognizing the success which the E U has achieved in economic and monetary union since the Treaty of Rome (1957); recognizing the varying levels of success which individual member countries have achieved in terms of their own welfare state policies, I ask what conditions might be necessary in order to achieve comparable success for social policy development and provision at the Union level. While recognizing the existence of myriad interpretations of the integration process (from neo-functionalism to intergovernmentalism, corporatism to pluralism), as well as the many tensions and social cleavages at play within the various societies of the Union, this study focuses on only two ethical/theoretical paradigms, and on two methods of governance which can or could be used for future European social policy development. These are the Ethic of Justice and the Ethic of Care, and the Community Method (or hard law approach) and the Co-Ordination Method (or soft law approach), respectively. The two principal questions addressed in this study are: 1) Which theoretical paradigm is best suited to address the complex process of European social policy integration? and 2) Which method, or mode of governance, would best operationalize this chosen normative paradigm? In attempting to answer these questions, the works of John Rawls, Ronald Dworkin, Jeremy Waldron and David Miller (justice), as well as those of Joan Tronto, Olena Hankivsky, Christine Koggel and Selma Sevenhuijsen, are discussed. An overview of the historical developments of integration within the social policy field is also offered as a means of emphasizing the continuity that exists within various soft law traditions of E U policy development. I also propose three different criteria of responsiveness with which to evaluate the two paradigms and governance methods. Finally, as a means of drawing upon the positive attributes of each theoretical framework and mode of governance, two hybrid or compromise solutions are proposed and analyzed, namely a Principled Ethic of Care and the Open Method of Co-Ordination.

description: Crop and animal production constitutes one of the main components of bio-economy. In Poland, legumes have gained more and more importance within crop production, as their cultivation has attracted attention both within agricultural and environmental programs that had been introduced, and for its environmental beneficiary effects. The present paper gives an overview of the research on estimating soybean production profitability compared to common legumes in Poland as field bean and yellow lupin. The studies have shown that the main factors affecting the profitability of growing legume crops in Poland are subsidies to production, costs of agricultural treatments and the obtained seeds yields.

description: In the present study, the diversity of ascomycete fungi was investigated on two wall areas of the “Burg Gleichen”, Thuringia (Germany), made of various types of sandstones, travertine and Grenzdolomit. From a W-exposed, shaded wall area, free-living ascomycetes (mainly “black fungi”) and green algae could be retrieved from sandstone lithologies. Sandstone from an ESE-exposed area was mainly colonized by lichen ascomycetes and the lichen alga Trebouxia. Both areas share a small number of generalist species, related to the ascomycete black fungi Sarcinomyces petricola, Phaeococcomyces chersonesos and Stichococcus mirabilis. Free-living black fungi were isolated and characterized with respect to cell wall morphology and melanin content. A remarkably rigid melanin layer, incorporated in the cell wall of a Cladosporium isolate is presented in detail.

description: The space telescope MOST is now providing us with extremely accurate low frequency p-mode oscillation data for the star Eta Boo. We demonstrate in this paper that these data, when combined with ground based measurements of the high frequency p-mode spectrum, can be reproduced with stellar models that include the effects of turbulence in their outer layers. Without turbulence, the l=0 modes of our models deviate from either the ground based or the space data by about 1.5-4.0 micro Hz. This discrepancy can be completely removed by including turbulence in the models and we can exactly match 12 out of 13 MOST frequencies that we identified as l=0 modes in addition to 13 out of 21 ground based frequencies within their observational 2 sigma tolerances. The better agreement between model frequencies and observed ones depends for the most part on the turbulent kinetic energy which was taken from a 3D convection simulation for the Sun.

description: Die Eischalenstruktur von Varanus komodoensis OUWENS 1912 (Komodowaran) wird mit verschiedenen Methoden untersucht (REM. Dünnschliffe. histologische Methoden. Fluorochromierungen. EDAX) und dokumentiert. Sie besteht aus einem wellblechartig arrangierten Geflecht organische Fasern. in die zentral eine Lage kalzitischer Sphärolithe integriert ist. Zusätzlich findet Mineralisation in kesseiförmigen Einheiten statt, in denen Kalzitkristalle die Anlage der Fasern nachzeichnen. Die Oberfläche der Schale wird durch eine dünne Schicht aus radialen bis mehr oder weniger kugeligen Kieselsäure-Aggregaten bedeckt. Der Vergleich mit den Eischalen von drei Varanus-Arten und anderen Squamaten zeigt. daß die Schalenstrukturierung auch unter funktionsmorphologischen Aspekten erfolgt.
description: Eggshell structure of Varanus komodoensis OUWENS 1912 (Komodo monitor) is analyzed using different methodes (SEM, thin sections, histological staining, fluorochromes, EDX) and documented. The shell consists of wavy organic fibres. Within the shell, a distinct layer of calcitic spherules can be recognized. Additionally, bigger kettle-like objects are fully mineralized, reflecting the wavy structure of the fibres. The outer surface of the shell is covered by a thin layer consisting of amorphous silica. The shell is compared with three other species of Varanus and other squamatic reptiles.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Hydrodynamical simulations of planet-disk interactions suggest that planets may be responsible for a number of the sub-structures frequently observed in disks in both scattered light and dust thermal emission. Despite the ubiquity of these features, direct evidence of planets embedded in disks and of the specific interaction features like spiral arms within planetary gaps still remain rare. In this study we discuss recent observational results in the context of hydrodynamical simulations in order to infer the properties of a putative embedded planet in the cavity of a transition disk. We imaged the transition disk SR 21 in H-band in scattered light with SPHERE/IRDIS and in thermal dust emission with ALMA band 3 (3mm) observations at a spatial resolution of 0.1". We combine these datasets with existing band 9 (430um) and band 7 (870um) ALMA continuum data. The Band 3 continuum data reveals a large cavity and a bright ring peaking at 53 au strongly suggestive of dust trapping.The ring shows a pronounced azimuthal asymmetry, with a bright region in the north-west that we interpret as a dust over-density. A similarly-asymmetric ring is revealed at the same location in polarized scattered light, in addition to a set of bright spirals inside the mm cavity and a fainter spiral bridging the gap to the outer ring. These features are consistent with a number of previous hydrodynamical models of planet-disk interactions, and suggest the presence of a ~1 MJup planet at 44 au and PA=11°. This makes SR21 the first disk showing spiral arms inside the mm cavity, as well as one for which the location of a putative planet can be precisely inferred. With the location of a possible planet being well-constrained by observations, it is an ideal candidate for follow-up observations to search for direct evidence of a planetary companion still embedded in its disk.

description: In this paper, we develop a framework for path-planning on abstractions that are not provided to the agent a priori but instead emerge as a function of the available computational resources. We show how a path-planning problem in an environment can be systematically approximated by solving a sequence of easier to solve problems on abstractions of the original space. The properties of the problem are analyzed, and a number of theoretical results are presented and discussed. A numerical example is presented to show the utility of the approach and to corroborate the theoretical findings. We conclude by providing a discussion detailing the connections of the proposed approach to anytime algorithms and bounded rationality.
Urban, Low-income Youth: Chronic Stress, Psychological Symptoms, and the Impact of Parental Involvement
Creators: name: Fellner, Lauren B.
Publisher: name: American University

description: This study sought to determine the manner in which urban stressors impact adolescent psychological functioning and the role of the parent-adolescent relationship as a buffer against symptoms. Two hundred fifty-nine urban, low-income, predominantly African American and Latino adolescents in the Chicago Public School System were administered surveys questioning their exposure to stressors (i.e., exposure to violence, major life events, daily hassles), psychological symptoms (i.e., measures of internalizing and externalizing), and levels of mother and father attachment. Pearson correlations and linear regressions demonstrated that, generally, as stress increased, psychological symptoms increased. Mother and father attachment moderated the relationships between stressors and symptoms such that they weakened the strength of these relationships. Exposure to violence demonstrated fewer significant effects than other stressors, which may be explained by the normalization of violence in urban environments. This study highlights the importance of prevention and intervention in early adolescence to enhance mental health.

description: We derive general formulas for photon and dilepton production rates from an arbitrary non-equilibrated medium from first principles in quantum field theory. At lowest order in the electromagnetic coupling constant, these relate the rates to the unequal-time in-medium photon polarization tensor and generalize the corresponding expressions for a system in thermodynamic equilibrium. We formulate the question of electromagnetic radiation in real time as an initial value problem and consistently describe the virtual electromagnetic dressing of the initial state. In the limit of slowly evolving systems, we recover known expressions for the emission rates and work out the first correction to the static formulas in a systematic gradient expansion. Finally, we discuss the possible application of recently developed techniques in non-equilibrium quantum field theory to the problem of electromagnetic radiation. We argue, in particular, that the two-particle-irreducible (2PI) effective action formalism provides a powerful resummation scheme for the description of multiple scattering effects, such as the Landau-Pomeranchuk-Migdal suppression recently discussed in the context of equilibrium QCD.
