description: Adopting the SPECTRUM package, we have synthesized a set of 2,890 Near-InfraRed (NIR) synthetic spectra with a resolution and wavelength sampling similar to the SDSS and the forthcoming LAMOST spectra. During the synthesis, we have applied the `New grids of ATLAS9 Model Atmosphere' to provide a grid of local thermodynamic equilibrium (LTE) model atmospheres. This synthetic stellar library is composed of 1,350 solor scaled abundance (SSA) and 1,530 non-solar scaled abundance (NSSA) spectra, grounding on which we have defined a new set of NIR CaII triplet indices and an index CaT as the sum of the three. Then, these defined indices have been automatically measured on the synthetic spectra and calibrated with the indices computed on the observational spectra from the INDO-U.S. stellar library. In order to check the effect of alpha-element enhancement on the so-defined CaII indices, we have compared indices measured on the SSA spectra with those on the NSSA ones at the same terns of stellar parameters (Teff, log g, [Fe/H]), and luckily, little influences of alpha-element enhancement has been found. Furthermore, comparisons of synthetic indices with the observational ones from the INDO-U.S. spectra, the SDSS-DR7, and DR8 spectroscopic survey have been presented respectively for dwarfs and giants in detail. Finally, a new synthetic library of NIR CaII indices has been founded for deeper studies on the NIR waveband of stellar spectra, and is particularly appropriate for the SDSS and the forthcoming LAMOST stellar spectra. Later on, we have regressed the strength of the CaT index as a function of stellar parameters for both dwarfs and giants after a series of experimental investigations into relations of the indices with stellar parameters. Ultimately, a supplemental experimentation has been carried out to show that spectral noises do have effects on our set of NIR CaII indices.

description: The effect of competing nonlinearity on beam dynamics in parity-time $(\mathcal{PT})$ symmetric potentials is investigated. By using numerical methods, the existence of gap solitons is demonstrated in the first Bragg gap of optical $\mathcal{PT}$ symmetric lattices with competing nonlinearity. Meanwhile, the stability of such solitons is analyzed through introducing a small perturbation to the solitary solutions. The abrupt annihilation of the solitons during propagation demonstrates the Bragg gap solitons in $\mathcal{PT}$ symmetric potentials are not stable. In comparison with the on-site gap solitons, the off-site gap solitons exhibit more robust properties during propagation.

Although non-standard astronomical setup has been used to generate pseudodata sets for our analyses, it has been found that, without prior information/assumption about the local density and velocity distribution of halo Dark Matter, these WIMP properties have been reconstructed with ~5% to < ~40% deviations from the input values.

description: The regular and chaotic character of orbits is investigated in a 3D potential describing motion in the central parts of a barred galaxy. This potential is an extension in the 3D space of a 2D potential based on a family of figure-eight orbits, which was produced using the theory of the inverse problem. Starting from the results obtained from the 2D system, we proceed to locate the regions in the phase space of the 3D potential, producing regular or chaotic orbits. In order to obtain this we use a new dynamical parameter, the S(c) spectrum, which proves to be a useful and fast indicator in order to distinguish regular motion from chaos in 3D potentials. Comparison with other methods for detecting chaos is also discussed.

description: Transport experiments provide conflicting evidence on the possible existence of fractional order within integer quantum Hall systems. In fact integer edge states sometimes behave as monolithic objects with no inner structure, while other experiments clearly highlight the role of fractional substructures. Recently developed low-temperature scanning probe techniques offer today an opportunity for a deeper-than-ever investigation of spatial features of such edge systems. Here we use scanning gate microscopy and demonstrate that fractional features were unambiguously observed in every integer quantum Hall constriction studied. We present also an experimental estimate of the width of the fractional incompressible stripes corresponding to filling factors 1/3, 2/5, 3/5, and 2/3. Our results compare well with predictions of the edge-reconstruction theory.

title: Angela Davis und Queer BDS. Was hat Palästina mit Feminismus zu tun?
Creators: name: Stögner, Karin
Year: 2023
Subjects: subject: 300 Sozialwissenschaften

description: Dass der palästinensische Kampf für nationale Selbstbestimmung eine feministische Angelegenheit sei, wird in akademischen und aktivistischen feministischen Zusammenhängen immer häufiger behauptet. Dahinter steht eine Allianz zwischen der Boycott Divestment Sanctions-Kampagne und intersektionalem und queerem Feminismus – Queer BDS. Dieser Beitrag analysiert die politische Agenda von Queer BDS und geht der Frage nach, welche Rolle queeren und feministischen Anliegen in den besetzten Gebieten tatsächlich zukommt. Dabei wird aufgezeigt, dass im Kampf um nationale Selbstbestimmung die Rechte von Frauen und LGBTIQ* mehr für eine antiisraelische Agitation instrumentalisiert als tatsächlich ernst genommen werden. Nach einer eingehenden Auseinandersetzung mit Angela Davis‘ Konzept der intersectionality of struggles stellt der Beitrag die Konflikte innerhalb der palästinensischen Community in den Vordergrund, die von Queer BDS verleugnet werden. Zum Abschluss wird ein emanzipatorischer intersektionaler Zugang zur Problematik queeren Lebens in Israel und den palästinensischen Gebieten skizziert, der von der Vielschichtigkeit und Widersprüchlichkeit der Kämpfe ausgeht, anstatt sie in antizionistische Richtung zu vereindeutigen.

A Suzaku Observation of MCG-2-58-22: Constraining the Geometry of the Circumnuclear Material

description: We have analyzed a Suzaku long-look of the active galactic nucleus MCG-2-58-22, a type 1.5 Seyfert with very little X-ray absorption in the line of sight and prominent features arising from reflection off circumnuclear material: the Fe line and Compton reflection hump. We place tight constraints on the power law photon index (Gamma=1.80+/-0.02), the Compton reflection strength (R=0.69+/-0.05), and the Fe K emission line energy centroid and width (E=6.40+/-0.02 keV, v_FWHM < 7100 km/s). We find no significant evidence for emission from strongly ionized Fe, nor for a strong, relativistically broadened Fe line, indicating that perhaps there is no radiatively efficient accretion disk very close in to the central black hole. In addition we test a new self-consistent physical model from Murphy & Yaqoob, the "MYTorus" model, consisting of a donut-shaped torus of material surrounding the central illuminating source and producing both the Compton hump and the Fe K line emission. From the application of this model we find that the observed spectrum is consistent with a Compton-thick torus of material (column density NH=3.6(+1.3/-0.8) x 10^24 cm^-2) lying outside of the line of sight to the nucleus, leaving it bare of X-ray absorption in excess of the Galactic column. We calculate that this material is sufficient to produce all of the Fe line flux without the need for any flux contribution from additional Compton-thin circumnuclear material.

title: The effects of perceived control and regulatory focus on outcomes of online interactions
Creators: name: Walsh, Aleksandra
Publisher: name: University of Reading
Year: 2024

description: The present study focuses on understanding the effects of customers’ perception of control and 
regulatory focus on outcomes of online interactions. This thesis aims to examine how 
customers’ perception of control over website interactions influences customers’ emotions, 
trust, and intended behaviour towards a company, as well as to establish the role of customers’ 
regulatory focus impacting the relationships. This research argues that customers’ perception 
of control, customers’ emotions, trust, intended behaviour and regulatory focus orientation 
have been studies in isolation and more research is needed to fill knowledge gap on 
understanding the dynamics between the constructs. Hence, drawing upon the literature in 
online consumer behaviour, and specifically on Theory of Planned Behaviour, Cognitive 
Appraisal Theory, Trust literature, and Regulatory Focus Theory, this study extends the 
Stimuli-Organism-Response (S-O-R) Framework by conceptualising that customers’ 
perception of control over website interactions shapes customers’ emotions, and drives trust 
and intended behaviour towards a company, whilst customers’ regulatory focus orientation 
moderates these relationships. To achieve the research objectives, the PhD thesis conducts a 
quantitative survey research design in the context of buying a mobile phone contract on 
Vodafone’s website. Data was collected from a sample of 300 Vodafone respondents (18+). 
This research adopts structural equation modelling partial least squares to analyse the data. 
Moderating effect of customers’ regulatory focus is examined using multigroup Analysis. The 
findings demonstrate three important theoretical contributions. First, the findings determine 
that customers’ perception of control over website interactions has stronger associations with 
customers’ emotions rather than customers’ trust towards a company. Next, this thesis 
establishes that customers’ perception of control over website interactions influence intended 
behaviour towards a company only through mediating constructs of customers’ emotions and 
trust. Finally, the research shows that customers’ regulatory focus moderates the relationship 
between customers’ perception of control over website interactions and negative emotions, in 
addition to moderating the relationship between negative emotions and trust towards a
company. These novel findings have important theoretical and managerial contributions. This 
thesis has some limitations, such as the study was conducted in particular context with specific 
set of customers. This creates a challenge of generalisability of the findings to other context. 
This PhD thesis addresses the potential limitations and suggests potential future research 
avenues.

Supporting Information for "Vegetal Polyphenol Extracts as Antioxidants for the Stabilization of PLA: Toward Fully Biobased Polymer Formulation"
Creators: name: Askanian, Haroutioun
Publisher: name: Zenodo
Year: 2024

description: The use of natural antioxidants as substitutes for traditional synthetic stabilizers has been investigated for the stabilization of biobased and biodegradable polymers, with the aim of designing fully biobased plastic formulations. This study focused on the thermo- and photostabilization of poly(lactic acid) (PLA) using vegetal polyphenol extracts as biosourced antioxidants. The polyphenols were extracted by microwave-assisted extraction from the valorization of vegetal waste, and their potential as antioxidant additives was evaluated (e.g., polyphenol content, composition, and antioxidant activity). PLA was then formulated with 2 wt % of the extracts exhibiting the highest antioxidant activities: green tea residues, pomegranate peels, grape marc, bramble leaves, and yellow onion peel extracts. The efficiency of the natural additives as thermal stabilizers was evaluated and compared with a synthetic antioxidant using rheological and thermal analyses. The results demonstrated the capacity of grape marc extract and pomegranate peel extract to significantly improve PLA thermal stability during processing and thermo-oxidation. Finally, photorheology was conducted to evaluate the influence of the bioadditives on the biopolyester photodegradation. The different polyphenol extracts seemed to significantly hinder the photo-oxidation of PLA and constitute very promising natural UV stabilizers, combining UV absorbers and antioxidant functions.

Supporting information contains: Data from LC–MS of vegetal extracts, TGA of vegetal extracts, TGA and DSC of PLA materials

The occurrence of A. hamondi in several caves and a spring in the Gnangara Mound region extends its known distribution to the south-west of Western Australia and supports Karanovic’s (2004a) premise that this species is stygobitic.

description: Auf den Punkt ...
Arbeitszeitkonten erfahren in den letzten Jahren eine immer größere Verbreitung. Soweit die jeweiligen Unternehmen keine Insolvenzsicherung dieser Konten vornehmen, besteht im Falle der Insolvenz für die Beschäftigten die Gefahr des Verlustes ihrer Guthaben.
Obwohl gesetzliche Grundlagen, tarifvertragliche Vereinbarungen und verschiedene Möglichkeiten der Insolvenzsicherung von Arbeitszeitguthaben vorhanden sind, trifft nur eine Minderheit von Betrieben Vorkehrungen zum Insolvenzschutz.
Die Ursachen dafür liegen nicht in einem vermeintlich zu großen bürokratischen Aufwand oder zu hohen Kosten für die Unternehmen. Analysen zeigen vielmehr, dass fehlendes Verantwortungs- und Problembewusstsein von betrieblichen Akteuren der Grund für die mangelnde Verbreitung ist.
Die vorhandenen regulativen Grundlagen in Gesetzen und Tarifverträgen sind meistens sehr unverbindlich und reichen nicht aus, um eine flächendeckende Verbreitung der Insolvenzsicherung von Arbeitzeitguthaben sicherzustellen.
Deshalb müssen die gesetzlichen Grundlagen so weiter entwickelt werden, dass es Unternehmen nicht mehr möglich ist, ihre Pflicht zur Insolvenzsicherung zu umgehen.

description: In this presentation, we discuss the nucleation and subsequent evolution of false vacuum bubbles in the scalar-tensor gravity. First, we transform the scalar-tensor type theory of gravity to the standard Brans-Dicke type. Second, we transform the Brans-Dicke type theory from the Jordan frame to the Einstein frame. For a certain potential, a true vacuum bubble in the Einstein frame can be transformed to a false vacuum bubble in the Jordan frame by a conformal transformation. Thus, in the Jordan frame, the nucleation of a false vacuum bubble can be possible and its subsequent evolution can be described with the help of thin-wall approximation. False vacuum bubbles have physical importance: a set of false vacuum bubbles might generate a negative energy bath and it has further theoretical implications.

Rock Dynamic Drilling

description: The method of percussive rotary drilling is recognized as the most efficient method for hard rock drilling. Despite the clear advantages over conventional rotary meth-ods, there are still uncertainties associated with percussive rotary drilling. For geothermal applications, it is estimated that 50 % of the total cost per installed megawatt of energy is associated with drilling and well construction, with drill bit wear being a predominant cost factor. Numerical modelling and simulation of rock drilling, calibrated and validated towards rigorous experiments, can give insight into the rock drilling process. This thesis is focused on the prerequisites of numer-ical simulations of rock drilling, i.e. the development of a numerical model and experimental characterization of rock materials. A new approach for modelling brittle heterogeneous materials was developed in this work. The model is based on the Bonded Particle Method (BPM) for the Discrete Element Method (DEM), where heterogeneity is introduced in two ways. Firstly, the material grains are rep-resented by random, irregular ellipsoids that are distributed throughout the body. Secondly, these grains are constructed using the BPM-DEM approach with mi-cromechanical parameters governed by the Weibull distribution. The model was applied to the Brazilian Disc Test (BDT), where crack initiation, propagation, coalescence and branching could be investigated for different levels of heterogene-ity and intergranular cement strengths. The initiation and propagation of the cracks were found to be highly dependent on the level of heterogeneity and cement strengths. In the experimental study, the static and dynamic properties of two rock materials - Kuru grey granite and Kuru black diorite - were obtained from uniaxial compression and indirect tension tests. A Split-Hopkinson Pressure Bar was used to obtain the dynamic properties. Using high-speed photography with frame rate 663,000 fps, the crack initiation and propagation could be studied in de-tail, and the full-field exterior deformation fields of the samples were evaluated by using digital image correlation. From the high-speed images, the onset of unstable crack growth was detected. The crack-damage stresses, associated with unstable crack growth, was approx. 90 % of the peak strength in the dynamic compression tests, whereas the tensile crack-damage stress was approx 70 % of the tensile peak strength.

description: This study was aim to the Analysis of Mother, Neonates and Children Health commodities supply chain management in Addis Ababa City Administration Health Bureau facilities using descriptive study by utilizing both primary and secondary data. The quantitative data was collected using modified Logistics Indicator assessment tool from selected health facilities Pharmacy store. From total of 101 health facilities (95 Health centers and 6 hospitals) in Addis Ababa the study sample was selected considering 90% confidence level (z), 10% margin of error (e) and 0.5 estimated outcome of the interest or proportion (p) then by adjusting using finite population correction factor (FPC), 40 health facilities were found and selected using random sampling method by putting all the sites in alphabetic order. Finally, the result was analyzed using SPSS & Excel and presented in graphs and table form. Accordingly, even if 14 Mother, Neonates and Children Health commodities were selected to avail freely at facility level by Federal Ministry of Health, the study found an average of only 7.5 commodities were managed per facility which go as low as 4 and as high as 12. Despite low number of commodities were managed, their recording system was good enough as an average of 98.7% have bin cards in place and 93% were updating their bin cards. Reporting by using Internal Facility Report & Resupply form and schedule showed 75% of facilities were using Internal Facility Report & Resupply form and keeping schedule to resupply the dispensing unit from store. Also, the use of Report & Requisition Form for reporting and resupply found to be 85% of which 75% were sending to Pharmaceutical Fund Supply Agency. But the perceived refill rate was low, as 60% of facilities were perceived they were not refilled according to the request. Their storage condition showed with different criteria as high as 100% and the lowest was 80% of facilities fulfilling the necessary standard for storage

description: We study the structure of the Mordell--Weil group of elliptic curves over number fields of degree 2, 3, and 4. We show that if $T$ is a group, then either the class of all elliptic curves over quadratic fields with torsion subgroup $T$ is empty, or it contains curves of rank~0 as well as curves of positive rank. We prove a similar but slightly weaker result for cubic and quartic fields. On the other hand, we find a group $T$ and a quartic field $K$ such that among the elliptic curves over $K$ with torsion subgroup $T$, there are curves of positive rank, but none of rank~0. We find examples of elliptic curves with positive rank and given torsion in many previously unknown cases. We also prove that all elliptic curves over quadratic fields with a point of order 13 or 18 and all elliptic curves over quartic fields with a point of order 22 are isogenous to one of their Galois conjugates and, by a phenomenon that we call \emph{false complex multiplication}, have even rank. Finally, we discuss connections with elliptic curves over finite fields and applications to integer factorization.

description: Contrary to the common view voids have very complex internal structure and dynamics. Here we show how the hierarchy of structures in the density field inside voids is reflected by a similar hierarchy of structures in the velocity field. Voids defined by dense filaments and clusters can de described as simple expanding domains with coherent flows everywhere except at their boundaries. At scales smaller that the void radius the velocity field breaks into expanding sub-domains corresponding to sub- voids. These sub-domains break into even smaller sub-sub domains at smaller scales resulting in a nesting hierarchy of locally expanding domains. The ratio between the magnitude of the velocity field responsible for the expansion of the void and the velocity field defining the sub voids is approximately one order of magnitude. The small-scale components of the velocity field play a minor role in the shaping of the voids but they define the local dynamics directly affecting the processes of galaxy formation and evolution. The super-Hubble expansion inside voids makes them cosmic magnifiers by stretching their internal primordial density fluctuations allowing us to probe the small scales in the primordial density field. Voids also act like time machines by "freezing" the development of the medium-scale density fluctuations responsible for the formation of the tenuous web of structures seen connecting proto galaxies in computer simulations. As a result of this freezing haloes in voids can remain "connected" to this tenuous web until the present time. This may have an important effect in the formation and evolution of galaxies in voids by providing an efficient gas accretion mechanism via coherent low-velocity streams that can keep a steady inflow of matter for extended periods of time.

description: We present a time-splitting spectral scheme for the Maxwell-Dirac system and similar time-splitting methods for the corresponding asymptotic problems in the semi-classical and the non-relativistic regimes. The scheme for the Maxwell-Dirac system conserves the Lorentz gauge condition, is unconditionally stable and highly efficient as our numerical examples show. In particular we focus in our examples on the creation of positronic modes in the semi-classical regime and on the electron-positron interaction in the non-relativistic regime. Furthermore, in the non-relativistic regime, our numerical method exhibits uniform convergence in the small parameter $\dt$, which is the ratio of the characteristic speed and the speed of light.

description: The implications of causality, as captured by the Kramers-Kronig relations between the real and imaginary parts of a linear response function, are familiar parts of the physics curriculum. In 1937, Bode derived a similar relation between the magnitude (response gain) and phase. Although the Kramers-Kronig relations are an equality, Bode's relation is effectively an inequality. This perhaps-surprising difference is explained using elementary examples and ultimately traces back to delays in the flow of information within the system formed by the physical object and measurement apparatus.

description: A supersonic beam of metastable neon atoms has been decelerated by exploiting the interaction between the magnetic moment of the atoms and time-dependent inhomogeneous magnetic fields in a multistage Zeeman decelerator. Using 91 deceleration solenoids, the atoms were decelerated from an initial velocity of 580m/s to final velocities as low as 105m/s, corresponding to a removal of more than 95% of their initial kinetic energy. The phase-space distribution of the cold, decelerated atoms was characterized by time-of-flight and imaging measurements, from which a temperature of 10mK was obtained in the moving frame of the decelerated sample. In combination with particle-trajectory simulations, these measurements allowed the phase-space acceptance of the decelerator to be quantified. The degree of isotope separation that can be achieved by multistage Zeeman deceleration was also studied by performing experiments with pulse sequences generated for $^{20}$Ne and $^{22}$Ne.

description: Este trabalho realiza uma análise discursiva do gênero capa de revista, com base na perspectiva da Análise de Discurso Francesa, partimos do pressuposto que o processo analítico começa pela transformação da superfície linguística em um objeto discursivo, incluindo a configuração do corpus e a delimitação de seus contornos (Orlandi 2009) Os objetivos desta pesquisa são: a) analisar os enunciados das capas da Revista Vogue à luz da teoria da Análise do Discurso como objetos simbólicos que produzem significados, e b) investigar os possíveis efeitos de sentido relacionados ao corpo plus size, negro e feminino apresentado em uma capa de revista de moda. Uma das interpretações que emerge deste estudo está relacionada à sociedade capitalista e aos discursos que moldam as normas para a aceitação dos corpos femininos no contexto de consumo. O corpus selecionado consiste na análise da capa da Revista Vogue que traz como materialidade imagética a fotografia da modelo Precious Lee. Do ponto de vista temporal, a capa analisada circulou nos meses de junho a julho de 2021. Sobre os resultados destacamos que a capa analisada se torna um enunciado concreto por se situarem historicamente e por, concretamente, convocarem sentidos que possibilitam a compreensão dos posicionamentos ideológicos do veículo de comunicação midiático que atravessa ideologicamente os sujeitos.

description: The cluster complex $Δ(Φ)$ is an abstract simplicial complex, introduced by Fomin and Zelevinsky for a finite root system $Φ$. The positive part of $Δ(Φ)$ naturally defines a simplicial subdivision of the simplex on the vertex set of simple roots of $Φ$. The local $h$-vector of this subdivision, in the sense of Stanley, is computed and the corresponding $γ$-vector is shown to be nonnegative. Combinatorial interpretations to the entries of the local $h$-vector and the corresponding $γ$-vector are provided for the classical root systems, in terms of noncrossing partitions of types $A$ and $B$. An analogous result is given for the barycentric subdivision of a simplex.

description: Connected Health solutions are ubiquitous in providing patient centered care and in responding to a new paradigm of care pathways where Health Information Technology is being introduced. This paper defines Connected Health, and, in particular, describes standards and regulations which are important to the implementation of safe, effective and secure Connected Health solutions. This paper provides: a holistic view of Connected Health; provides a standards and regulations based view of the lifecycle of the Health IT system; and identifies the relevant roles and responsibilities at the various stages of the lifecycle for both manufacturers of connected health solution and healthcare delivery organization solutions. We discuss how the implementation of standards and regulations, while implementing and using Health IT infrastructure, requires close collaboration and ongoing communication between Healthcare Delivery Organizations and Accountable Manufacturers throughout the lifecycle of the health IT system. Furthermore, bringing technology into the healthcare system requires a robust and comprehensive approach to Clinical Change Management to support the business and clinical changes that the implementation of such solutions requires. Ultimately, to implement safe, effective, and secure Connected Health solutions in the healthcare ecosystem, it requires that all those involved work together so that the main requirement—patient-centered care—is realized.
Spin Liquids and Antiferromagnetic Order in the Shastry-Sutherland-Lattice Yb$_{2}$Pt$_{2}$Pb

description: We present measurements of the magnetic susceptibility $χ$ and the magnetization M of single crystals of metallic \ypp, where localized Yb moments lie on the geometrically frustrated Shastry-Sutherland Lattice (SSL). Strong magnetic frustration is found in this quasi-two dimensional system, which orders antiferromagnetically (AF) at T$_{N}$=2.02 \emph{K} from a paramagnetic liquid of Yb-dimers, having a gap $Δ$=4.6 \emph{K} between the singlet ground state and the triplet excited states. Magnetic fields suppress the AF order, which vanishes at a 1.25 \emph{T} quantum critical point. The spin gap $Δ$ persists to 1.5 \emph{T}, indicating that the AF degenerates into a liquid of dimer triplets at T=0. Quantized steps are observed in M(B) within the AF state, a signature of SSL systems. Our results show that \ypp is unique, both as a metallic SSL system that is close to an AF quantum critical point, and as a heavy fermion compound where geometrical frustration plays a decisive role.
