description: We present a brief summary of the Single Degenerate Scenario for the progenitors of Type Ia Supernovae in which it is assumed that a low mass carbon-oxygen white dwarf is growing in mass as a result of accretion from a secondary star in a close binary system. Recent hydrodynamic simulations of accretion of solar material onto white dwarfs without mixing always produce a thermonuclear runaway and steady burning does not occur. For a broad range in WD mass (0.4 Solar masses to 1.35 Solar Masses), the maximum ejected material occurs for the 1.25 Solar Mass sequences and then decreases as the white dwarf mass decreases. Therefore, the white dwarfs are growing in mass as a consequence of the accretion of solar material and as long as there is no mixing of accreted material with core material. In contrast, a thermonuclear runaway in the accreted hydrogen-rich layers on the low luminosity WDs in close binary systems where mixing of core matter with accreted material has occurred is the outburst mechanism for Classical, Recurrent, and Symbiotic novae. The differences in characteristics of these systems is likely the WD mass and mass accretion rate. The high levels of enrichment of CN ejecta in elements ranging from carbon to sulfur confirm that there is dredge-up of matter from the core of the WD and enable them to contribute to the chemical enrichment of the interstellar medium. Therefore, studies of CNe can lead to an improved understanding of Galactic nucleosynthesis, some sources of pre-solar grains, and the Extragalactic distance scale. The characteristics of the outburst depend on the white dwarf mass, luminosity, mass accretion rate, and the chemical composition of both the accreting material and WD material. The properties of the outburst also depends on when, how, and if the accreted layers are mixed with the WD core and the mixing mechanism is still unknown.

description: In this work we aim at understanding the effect of n-type and p-type substitutional doping in the case of matrix-embedded and freestanding Si nanocrystals. By means of ab-initio calculations we identify the preferential positioning of the dopants and its effect on the structural properties with respect to the undoped case. Subsequently, we consider the case of phosphorus and boron co-doped nanocrystals showing that, against the single-doping situation, the energetics strongly favors the binding of the impurities at the NC surface. Indeed we demonstrate that the polar B-P bond forms a stable permanent electric dipole that radially points inwards the nanocrystal. Such noteworthy characteristic and its physical consequences are discussed alongside new potential applications.
Stepping up: an empirical analysis of the role of social innovation in response to an economic recession

description: Categorising organisations as either for-profit or nonprofit is a false dichotomy as existing for-profit firms are becoming more socially conscience while nonprofits are adopting profit-making activities to ensure their viability. This paper conceptualises the array of social practices as a continuum of social innovation and empirically demonstrates variation not captured by legal designation. Using a survey from the US state of North Carolina, this paper examines how organisations across the continuum responded to the 2008 economic recession. Results indicate that more socially innovative organisations responded to the increase in need by increasing environmental, community and employee support.

description: A kinetic-fluid model describing the evolutions of disperse two-phase flows is considered. The model consists of the Vlasov-Fokker-Planck equation for the particles (disperse phase) coupled with the compressible Navier-Stokes equations for the fluid (fluid phase) through the friction force. The friction force depends on the density, which is different from many previous studies on kinetic-fluid models and is more physical in modeling but significantly more difficult in analysis. New approach and techniques are introduced to deal with the strong coupling of the fluid and the particles. The global well-posedness of strong solution in the three-dimensional whole space is established when the initial data is a small perturbation of some given equilibrium. Moreover, the algebraic rate of convergence of solution toward the equilibrium state is obtained. For the periodic domain the same global well-posedness result still holds while the convergence rate is exponential.

description: If $\Phi_\lambda$ is a master function corresponding to a hyperplane arrangement $\mathcal A$ and a collection of weights $\lambda$, we investigate the relationship between the critical set of $\Phi_\lambda$, the variety defined by the vanishing of the one-form $\omega_\lambda=\operatorname{d} \log \Phi_\lambda$, and the resonance of $\lambda$. For arrangements satisfying certain conditions, we show that if $\lambda$ is resonant in dimension $p$, then the critical set of $\Phi_\lambda$ has codimension at most $p$. These include all free arrangements and all rank $3$ arrangements.

title: Ausarbeitung eines Monographievorschlags "Epilobii angustifolii herba" für das Österreichische Arzneibuch
Creators: name: Zsulits, Barbara
Year: 2023

description: Die Arzneidroge Epilobii angustifolii herba wird seit mehreren Jahrzehnten in österreichischen Apotheken als Teedroge abgegeben. Der Einsatz bei benigner Prostatahyperplasie hat sich in der Praxis bewährt. Nachdem der Ausschuss für pflanzliche Arzneimittel bei der Europäischen Arzneimittelagentur eine EU-Pflanzenmonographie zur traditionellen medizinischen Verwendung von Epilobii herba verabschiedet hat, erschien es erforderlich auch eine verbindliche Qualitätsreferenz zu definieren. Deshalb sollte im Rahmen dieser Masterarbeit ein Monographievorschlag für das Österreichische Arzneibuch für Epilobii angustifolii herba erarbeitet werden. Zur Erarbeitung bzw. Überprüfung von Kriterien zur Prüfung der Identität wurden eindeutig identifizierte Exemplare von Epilobium angustifolium, Epilobium dodonaei (Sektion Chamenaerion), Epilobium hirsutum und weiteren Vertretern der Kleinblütigen Arten aus eigenen Aufsammlungen herangezogen. Um realitätsnahe Kriterien für die Reinheitsprüfung auszuarbeiten wurden auch sieben Handelsmuster in die Untersuchungen einbezogen. Auf Basis der authentifizierten Aufsammlungen wurden Vorschläge für die makroskopische und mikroskopische Identifizierung erarbeitet. Vor allem die Verteilung der raphidenbündelführenden Idioblasten streng entlang der Leitbündel der Blätter erlaubt eine eindeutige Identifizierung von Epilobium angustfolium. Auch der chromatographische Fingerprint der Flavonoide von Epilobium angustifolium unterscheidet sich eindeutig von allen anderen Arten der Gattung Epilobium. Die Festlegung der Grenzwerte für die Reinheitsprüfungen Trocknungsverlust und Asche erfolgte mit Handelsmustern von Epilobii angustifolii herba. Die vorgeschlagenen Werte von 10,0% für den Trocknungsverlust und 8% für die Asche entsprechen den üblichen Werten für pflanzliche Drogen im Europäischen Arzneibuch. Die Bestimmung des Gerbstoffgehalts nach der Methode des Europäischen Arzneibuchs ergab Werte zwischen ca. 2% und 8%. Da die Methode komplex ist und spezifische Reagentien erfordert, wurde auch die Menge der extrahierbaren Bestandteile bestimmt. Die ermittelten Werte korrellieren sehr gut mit dem Gerbstoffgehalt, weshalb für die ÖAB Monographie die wesentlich einfacher durchzuführende Prüfung der extrahierbaren Bestandteile mit einem Mindestwert von 27,0% als Ersatz für einen Assay vorgeschlagen wurde. Der Monographievorschlag wurde von der Arzneibuchkommission angenommen und als Monographie ÖAB 2021/217 im ÖAB 2021 publiziert.

description: Galaxy-scale outflows, which are thought to provide the link connecting the central black hole to its host galaxy, are now starting to be observed. However, the physical origin of the mechanism driving the observed outflows, whether due to energy-driving or radiation-driving, is still debated; and in some cases, it is not clear whether the central source is an active galactic nucleus (AGN) or a nuclear starburst. Here we study the role of radiation pressure on dust in driving galactic-scale AGN outflows, and analyse the dynamics of the outflowing shell as a function of the underlying physical parameters. We show that high-velocity outflows ($\gtrsim$1000 km/s) with large momentum flux ($\gtrsim 10 L/c$) can be obtained, by taking into account the effects of radiation trapping. In particular, the high observed values of the momentum boosts can be reproduced, provided that the shell is initially optically thick to the reprocessed infrared radiation. Alternatively, the inferred measurements of the momentum flux may be significantly biased by AGN variability. In this context, the observations of powerful outflows on kiloparsec scales, with no or weak signs of ongoing nuclear activity at the present time, could be re-interpreted as relics of past AGN episodes.

Party Dominance in 18 Countries: The Role of Party Dominance in the Transmission of Political Ideology
Creators: name: Huo, Jingjing
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2005

description: Abstract. Using OLS regression with World Values Survey data across 18 OECD countries, this article makes two major arguments. Firstly, if a dominant party is ideologically congruent with an individual, its dominance enhances the effect of party ideology on individual ideology. If incongruent, greater dominance only inhibits this effect. Secondly, if individuals find the dominant party ideologically congruent, as their political awareness increases, the effect of that party's ideology rises monotonically. If incongruent, the effect of party ideology first rises and then falls back. Therefore, party dominance leads ultimately to increasing ideological polarization between the dominant party's supporters and opponents. Résumé. Cet article vise à présenter deux arguments importants en appliquant la “ régression OLS ” aux données du “ World Values Survey ” sur 18 pays de l'OCDE. En premier lieu, s'il y a congruence entre l'idéologie d'un parti dominant et celle de l'individu, la dominance du parti renforce l'effet d'idéologie de parti sur l'idéologie de l'individu. S'il n'y a pas congruence d'idéologies, une dominance plus marquée du parti ne fait qu'entraver davantage cet effet. En second lieu, si les individus trouvent l'idéologie du parti dominant conforme à la leur, au fur et à mesure qu'augmente leur conscience politique, l'effet de l'idéologie de ce parti augmente de façon uniforme. Si l'idéologie du parti dominant n'est pas conforme à la leur, l'effet d'idéologie de parti commence par grandir pour ensuite retomber. Ainsi, la prédominance de parti mène finalement à une polarisation idéologique croissante entre les partisans du parti dominant et ses opposants.

description: Two-point functions, the mean field squared and the vacuum expectation value (VEV) of the energy-momentum tensor are investigated for the electromagnetic field in the geometry of parallel plates on background of $(D+1)$% -dimensional dS spacetime. We assume that the field is prepared in the Bunch-Davies vacuum state and on the plates a boundary condition is imposed that is a generalization of the perfectly conducting boundary condition for an arbitrary number of spatial dimensions. It is shown that for $D\geq 4$ the background gravitational field essentially changes the behavior of the VEVs at separations between the plates larger than the curvature radius of dS spacetime. At large separations, the Casimir forces are proportional to the inverse fourth power of the distance for all values of spatial dimension $D\geq 3$. For $D\geq 4$ this behavior is in sharp contrast with the case of plates in Minkowski bulk where the force decays as the inverse $(D+1)$th power of the distance.

description: Homological stability for sequences of groups is often proved by studying the spectral sequence associated to the action of a typical group in the sequence on a highly-connected simplicial complex whose stabilizers are related to previous groups in the sequence. In the case of mapping class groups of manifolds, suitable simplicial complexes can be made using isotopy classes of various geometric objects in the manifold. In this paper we focus on the case of surfaces and show that by using more refined geometric objects consisting of certain configurations of curves with arcs that tether these curves to the boundary, the stabilizers can be greatly simplified and consequently also the spectral sequence argument. We give a careful exposition of this program and its basic tools, then illustrate the method using braid groups before treating mapping class groups of orientable surfaces in full detail.

description: The mathematical construct of 'collection of elements' continues to inform neuroscientific discourse on consciousness. For example, Albright speaks of deconstructing "perceptual experience into a collection of simple sensory elements" (Leonardo 46: 19, 2013), while Kandel asserts that "mind is a set of processes carried out by the brain" (Neuron 80: 546, 2013). This state-of-affairs prevails in spite of the fact that sensations, unlike the structure-less elements of sets, are structured, and conscious experiences, unlike the cohesion-less sets, are characterized by cohesion or unity. Building on a naïve understanding of the notion of 'category', wherein every object of a category partakes in the essence defining the category and every transformation of objects preserves the essence of the category, I show how 'category of objects' provides the conceptual repertoire needed to characterize the nature of conscious experiences. Equally importantly, when viewed in light of the category of experiences, designers of user experiences appear to be well situated to contribute to the advancement of consciousness science. Summing up, I present a conceptual advance—from 'set of elements' to 'objects of category'—in a concise manner. Equally importantly, I wrote my manuscript in a manner that makes the mathematics of categories, which is the basis of my claims, intuitively-accessible to multidisciplinary audience. As such, my manuscript will inspire further studies of the category of experiences as an objectification of consciousness.
Advancing Regional Water Supply Planning to Develop Equitable and Robust Infrastructure Investment and Management Pathways
Creators: name: Gold, David
Publisher: name: Zenodo
Year: 2023

description: Globally, urban water utilities are challenged by increasingly severe droughts and growing water demands. In the United States, these challenges are compounded by increasing costs of new supply development and aging infrastructure that strain the budgets of local water utilities. Regional cooperation can help utilities face these challenges by improving the efficiency of existing water sources and exploiting economies of scale to reduce the capital cost of new infrastructure investment. Effective strategies must equitably balance the potentially divergent interests of regional partners, as regional conflict can destabilize partnerships and expose utilities to new risks. The presence of uncertainty in water supply planning problems heightens these risks by masking sources of potential inequity and instability. In this talk, I present my research that advances the development of equitable and robust infrastructure investment and management policies. Using a six-utility water supply partnership in the Research Triangle of North Carolina, I’ll first illustrate how reinforcement learning and multiobjective optimization aid the development of infrastructure investment and management policies that maintain robust performance to a wide range of future conditions. Next, I’ll introduce a new methodology that explores the vulnerability of candidate policies to deep uncertainties (e.g., climate change, demand growth), reveals potential sources of instability within the cooperative partnership, and maps power dynamics between regional actors. Results from the Research Triangle illustrate the potential benefits of regionally cooperative water supply planning but also highlight that regional and individual vulnerabilities are highly interdependent and evolve over time in unexpected ways. These findings emphasize the need to carefully design cooperative agreements that limit the potential for regional conflict. Beyond the Research Triangle, these results are broadly applicable to cooperative infrastructure investment and management problems globally.
title: Improving Multi-Object Selection and Manipulation in Extended Reality Head-Mounted Displays
Creators: name: Shi, Rongkai
Publisher: name: University of Liverpool Repository
Year: 2024

description: With advancements in hardware, Extended Reality (XR) Head-Mounted Displays (HMDs), including Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR) HMDs, are becoming more lightweight and powerful. XR HMDs support various input modalities, enabling rich interaction experiences that are different from those in traditional interactive systems. In the daily and professional usage of XR HMDs, object selection and manipulation are fundamental to interacting with objects in HMDs. Existing research has focused on enhancing interaction techniques for selecting and manipulating a single object in XR, which are insufficient for multi-object selection and manipulation, a more complex but common XR interaction scenario. 
Multi-object selection and manipulation can be common in XR applications like data visualization, 3D modeling, and building design. When a user has the same operation intentions for a large number of objects, selecting them first and manipulating them as a group would be less time-consuming and tedious compared to interacting with them one by one. However, the interaction techniques designed for interacting with a single object cannot be simply transferred for these complex operations. The interaction techniques for multi-object selection and manipulation require careful design and evaluation. 
This thesis presents explorations and evaluations of novel interaction techniques involving multiple input modalities for several representative multi-object selection and manipulation tasks in XR HMDs: (1) freehand gesture-based multi-object selection, (2) gaze-assisted and gesture-based region selection, (3) group-based object alignment, and (4) head-based mode switching. They were designed with analyses of interaction scenarios and evaluated from a series of user studies. Our findings from these user studies provide empirical knowledge of the proposed techniques for several multi-object selection and manipulation scenarios. In addition to the empirical findings, we also provide design recommendations to guide the future design and development of more usable interaction techniques for XR HMDs.

description: In this paper we combine the advantages of a model using global source sentence contexts, the Discriminative Word Lexicon, and neural networks. By using deep neural networks instead of the linear maximum entropy model in the Discriminative Word Lexicon models, we are able to leverage dependencies between different source words due to the non-linearity. Furthermore, the models for different target words can share parameters and therefore data sparsity problems are effectively reduced. By using this approach in a state-of-the-art translation system, we can improve the performance by up to 0.5 BLEU points for three different language pairs on the TED translation task.

description: Background Helicobacter pylori infection is known to decrease the incidences of autoimmune diseases and inflammatory bowel disease(IBD). Our aim was investigating the effect of H. pylori treatment in diabetes mellitus(DM) patients. Methods Adults with newly-diagnosed H. pylori infection or peptic ulcer disease(PUD) within the general population and DM population were identified from the National Health Insurance Research Database of Taiwan from 2000–2010. 79,181 patients were assigned to the 3 groups: general population with PUD without H. pylori treatment(PUD-HPRx in general population), DM patients with PUD without H. pylori treatment(PUD-HPRx in DM), and DM patients with PUD who received H. pylori treatment(PUD+HPRx in DM). Results Higher incidences of autoimmune diseases and IBD were observed in the PUD+HPRx in DM group than in the PUD-HPRx in general population and PUD-HPRx in DM groups (autoimmune diseases = 5.14% vs 3.47% and 3.65%; IBD = 5.60% vs 3.17% and 3.25%; P<0.0001). A lower all-cause mortality was noted in the PUD+HPRx in DM group (HR: 0.937, P<0.001) than in the PUD-HPRx in DM group. Trends of a higher incidence of IBD and a lower mortality in younger patients in the PUD+HPRx in DM group compared with the PUD-HPRx in DM group were noted. Conclusions The results revealed that H. pylori treatment increased the incidences of autoimmune diseases and IBD and decreased the all-cause mortality in the DM group with PUD. The effect was more significant in younger patients. This finding assists in realizing the influence of H. pylori treatment in the DM population.

This file enhances the existing Add Health contextual database through the addition of measures essential to understanding the determinants and sequelae of socioeconomic mobility. Specifically, it aims to characterize the socioeconomic mobility of Add Health participants at Wave I, IV, and V. Though the included variables report the mobility of people born from 1980 to 1991 at the U.S. tract- and county-levels and, therefore, remain constant across the waves of Add Health, the locations inhabited by respondents typically vary from wave to wave. In other words, these data provide measures of the opportunities for socioeconomic mobility for similarly aged people residing in the same tract or county as the Add Health respondent at a given wave. The timing of the mobility measures, however, remains invariant across waves.

description: We develop an efficient sampling method by simulating Langevin dynamics with an artificial force rather than a natural force by using the gradient of the potential energy. The standard technique for sampling following the predetermined distribution such as the Gibbs-Boltzmann one is performed under the detailed balance condition. In the present study, we propose a modified Langevin dynamics violating the detailed balance condition on the transition-probability formulation. We confirm that the numerical implementation of the proposed method actually demonstrates two major beneficial improvements: acceleration of the relaxation to the predetermined distribution and reduction of the correlation time between two different realizations in the steady state.

description: Cd3As2 is a newly booming Dirac semimetal with linear dispersion along all three momentum directions and can be viewed as 3D analog of graphene. As breaking of either time reversal symmetry or spatial inversion symmetry, the Dirac semimetal is believed to transform into Weyl semimetal with exotic chiral anomaly effect, while the experimental evidence of the chiral anomaly is still missing in Cd3As2. Here we report the magneto-transport properties of individual Cd3As2 nanowires. Large negative magnetoresistance (MR) with magnitude of -63% at 60 K and -11% at 300 K are observed when the magnetic field is parallel with the electric field direction, giving the evidence of the chiral magnetic effect in Cd3As2 nanowires. In addition, the critical magnetic field BC, where there is an extremum of the negative MR, increases with increasing temperature. As the first observation of chiral anomaly induced negative MR in Cd3As2 nanowires, it may offer valuable insights for low dimensional physics in Dirac semimetals.

description: Antimicrobial resistance (AMR) poses a serious threat to global public health. Yet vaccinations have been largely undervalued as a method to hinder AMR progression. This study examined the AMR impact of increasing pneumococcal conjugate vaccine (PCV) coverage in China. China has one of the world’s highest rates of antibiotic use and low PCV coverage. We developed an agent-based DREAMR (Dynamic Representation of the Economics of AMR) model to examine the health and economic benefits of slowing AMR against commonly used antibiotics. We simulated PCV coverage, pneumococcal infections, antibiotic use, and AMR accumulation. Four antibiotics to treat pneumococcal diseases (penicillin, amoxicillin, 3rd generation cephalosporins, and meropenem) were modeled with antibiotic utilization, pharmacokinetics, and pharmacodynamics factored into predicting AMR accumulation. Three PCV coverage scenarios were simulated over five years: (1) status quo with no change in coverage, (2) scaled coverage increase to 99% in 5 years, and (3) accelerated coverage increase to 85% over 2 years followed by 3 years to reach 99% coverage. Compared to the status quo, we found that AMR against penicillin, amoxicillin, and 3rd generation cephalosporins was significantly reduced by 1.74%, 19.19%, and 14.87% in the scaled scenario and by 2.87%, 29.97%, and 23.35% in the accelerated scenario. Cumulative costs due to AMR, including direct and indirect costs to patients and caretakers, were reduced by $2.76 billion in the scaled and $4.46 billion in the accelerated scenarios compared to the status quo. AMR benefits of vaccines are essential to quantify in order to drive appropriate investment.

description: We have studied a Fermi system with attractive $U(r)$-symmetric interaction at the finite temperatures by the quantum field renormalization group (RG) method. The RG functions have been calculated in the framework of dimensional regularization and minimal subtraction scheme up to five loops. It has been found that for $r\geq 4$ the RG flux leaves the system's stability region -- the system undergoes a first order phase transition. To estimate the temperature of the transition to superconducting or superfluid phase the RG analysis for composite operators has been performed using three-loops approximation. As the result this analysis shows that for $3D$ systems estimated phase transition temperature is higher then well known theoretical estimations based on continuous phase transition formalism.

A Potential Negative-Strand Open Reading Frame in Zika Virus

description: Zika virus (ZIKV) is a recently emergent flavivirus transmitted by mosquitoes that is medically important due to neurological complications in the fetuses of infected mothers in the form of microcephaly, and less frequently in adults seen with cases of Guillain-Barré syndrome. ZIKV has a positive-sense RNA genome with one open reading frame (ORF) that encodes a single polyprotein. Interestingly, we identified a 550 base potential ORF marked by characteristics of an internal ribosomal entry site and a Kozak sequence on the negative-strand of this positive-sense viral genome that appears to be conserved across all well-characterized strains of the virus. To investigate the effect of this potential open reading frame, we cloned the ZIKV viral genome with a knock-out mutation to ablate the start codon of the negative strand ORF. We determined that the virus was live and viable by infection of C6/36 and Vero cell lines followed by immunostaining. RT-PCR was used to amplify the region of the mutation to confirm the presence of viral RNA in the supernatant and that the knockout had not reverted. Low and high MOI growth curves were conducted with Veros and found that the knockout had greater cytopathic effects with similar rates of replication compared to the wildtype H/PF/2013 strain. This is the first evidence of a negative-strand coding sequence shown to affect the pathogenicity of a positive-sense RNA virus. By further exploring the role of this coding sequence, and reverse complement ORFs in other positive-sense RNA viruses, we can develop a better understanding of the pathogenicity of these viruses and be better prepared for future outbreaks.

Sulcal morphology

description: This protocol introduces a refined Paracingulate Sulcus (PCS) Classification Protocol for use with BrainVISA (https://brainvisa.info), aimed at improving the identification and classification of the PCS using 3D reconstructions of sulci. Expanding on the three-class criteria from Yücel et al. (2001) and the ‘Paracingulate Sulcus Measurement Protocol V2’ (https://doi.org/10.17863/CAM.102040), this protocol employs a more detailed five-class rating scale. It also advances earlier methods by assessing both the length and depth of the PCS in 3D, rather than just the length on 2D parasagittal slices, thus enhancing precision. The protocol has demonstrated good validity and reliability.

description: Traditional dye sensitized photo-electrochemical cells (DSPECs) rely on a multicomponent photo-redox system in which a chromophore and catalyst are bound to a supporting electrode; however, current p-type DSPECs are limited by poor electronic properties of the electrode. The Miller Lab has previously demonstrated an alternative photochemical approach in which a single molecule acting as both a light absorbing chromophore and a catalyst can facilitate efficient H2 gas evolution. As such, [Cp*Ir(bpy)(H)]+ was targeted for surface immobilization in hopes of generating a novel and unique DSPEC adept at producing H2 as a renewable energy source. Hydrogen production quantified via GC demonstrated a turn over frequency of 0.017 s-1 with a Faradaic Efficiency of 83.9 %. Further investigations of [IrIII-H]+ bound to various conductive and semi-conductive electrodes have shown a distinct surface-specific mechanism all while maintaining H2 formation. Here within, we present such a novel unimolecular surface specific self-quenching mechanism in which hydrogen reduction is maintained.
