description: We introduce a minimal model describing the physics of classical two-dimensional (2D) frustrated Heisenberg systems, where spins order in a non-planar way at T=0. This model, consisting of coupled trihedra (or Ising-$\mathbb{R}P^3$ model), encompasses Ising (chiral) degrees of freedom, spin-wave excitations and $\Z_2$ vortices. Extensive Monte Carlo simulations show that the T=0 chiral order disappears at finite temperature in a continuous phase transition in the 2D Ising universality class, despite misleading intermediate-size effects observed at the transition. The analysis of configurations reveals that short-range spin fluctuations and $\Z_2$ vortices proliferate near the chiral domain walls explaining the strong renormalization of the transition temperature. Chiral domain walls can themselves carry an unlocalized $\Z_2$ topological charge, and vortices are then preferentially paired with charged walls. Further, we conjecture that the anomalous size-effects suggest the proximity of the present model to a tricritical point. A body of results is presented, that all support this claim: (i) First-order transitions obtained by Monte Carlo simulations on several related models (ii) Approximate mapping between the Ising-$\mathbb{R}P^3$ model and a dilute Ising model (exhibiting a tricritical point) and, finally, (iii) Mean-field results obtained for Ising-multispin Hamiltonians, derived from the high-temperature expansion for the vector spins of the Ising-$\mathbb{R}P^3$ model.

A simple toy model of the advective-acoustic instability I. Perturbative approach
Creators: name: Foglizzo, T.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Some general properties of the advective-acoustic instability are described and understood using a toy model which is simple enough to allow for analytical estimates of the eigenfrequencies. The essential ingredients of this model, in the unperturbed regime, are a stationary shock and a subsonic region of deceleration. For the sake of analytical simplicity, the 2D unperturbed flow is parallel and the deceleration is produced adiabatically by an external potential. The instability mechanism is determined unambiguously as the consequence of a cycle between advected and acoustic perturbations. The purely acoustic cycle, considered alone, is proven to be stable in this flow. Its contribution to the instability can be either constructive or destructive. A frequency cut-off is associated to the advection time through the region of deceleration. This cut-off frequency explains why the instability favours eigenmodes with a low frequency and a large horizontal wavelength. The relation between the instability occurring in this highly simplified toy model and the properties of SASI observed in the numerical simulations of stellar core-collapse is discussed. This simple set up is proposed as a benchmark test to evaluate the accuracy, in the linear regime, of numerical simulations involving this instability. We illustrate such benchmark simulations in a companion paper.

description: A survivorship care plan (SCP) utilizing a survivorship planning tool (SPT) can improve the quality of care of cancer survivors as they move beyond their cancer treatment by helping restore a sense of power and control and promoting adherence with recommended treatment. Because SCPs are essential for cancer survivors’ wellbeing, the aim of this project was to develop a SPT specifically for Latinas with cervical cancer seen in a Gynecology-Oncology clinic setting. This project involved four professionals who served on a content expert review panel (ERP) and 10 Latina participants who composed the Latina review panel (LRP). The panel members engaged in a collaborative and iterative review and feedback process in reviewing draft copies of a proposed SPT. An additional panel of five expert healthcare providers and five Latinas participated in a survey that evaluated the final SPT for understandability, readability, inclusiveness, practicality, and usability using a 5-point Likert scale system (5 being highest). The ERP mean scores for the SPT ranged from a high of 4.8 for inclusiveness to scores of 4.2 for both understandability and readability, 3.8 for practicality, and 3.6 for usability (easy to complete). The LRP understandability and readability mean scores were 4.8 each, 5.0 for inclusiveness, and 4.0 for both practicality and usability. Both groups expressed concerns about limited time available during clinical visits to complete the SPT as well as responsibility for its upkeep. Reassurance was provided regarding the joint and collaborative process that would be undertaken with both the healthcare providers’ team and survivors to complete the SPT. iv In conclusion, healthcare providers play a pivotal role in improving health outcomes and quality of life for cancer survivors. Members of the healthcare team must be cognizant of the importance of cancer survivors having individualized SCPs and readily guide them in acquiring and maintaining a SPT.

description: The physical processes involved in the advective-acoustic instability are investigated with 2D numerical simulations. Simple toy models, developped in a companion paper, are used to describe the coupling between acoustic and entropy/vorticity waves, produced either by a stationary shock or by the deceleration of the flow. Using two Eulerian codes based on different second order upwind schemes, we confirm the results of the perturbative analysis. The numerical convergence with respect to the computation mesh size is studied with 1D simulations. We demonstrate that the numerical accuracy of the quantities which depend on the physics of the shock is limited to a linear convergence. We argue that this property is likely to be true for most current numerical schemes dealing with SASI in the core-collapse problem, and could be solved by the use of advanced techniques for the numerical treatment of the shock. We propose a strategy to choose the mesh size for an accurate treatment of the advective-acoustic coupling in future numerical simulations.

title: Differences in Debt Holdings and Financial Satisfaction Across Age During COVID
Creators: name: Law, Loryn Elaine
Publisher: name: Utah State University

description: Access to credit has allowed many individuals to reach their own version of the American dream as credit offers them resources to improve quality of life by buying homes, purchasing automobiles, funding higher education, and financing everyday needs. However, accumulating debt may have negative impacts on their financial satisfaction. Since the 2021 wave of the National Financial Capability Study (NFCS) was collected during the COVID-19 Pandemic, this study was able to look at how financial stressors (e.g., unexpected income drops, being laid-off, difficulty paying on-going bills), financial anxiety, and financial literacy variables (e.g., subjective financial knowledge, objective financial knowledge, perceived financial capability) during COVID were associated with debt holdings and financial satisfaction. This study further investigated how holding different debt types was associated with financial satisfaction and how these associations vary across three age groups.
Results of the study show that individuals who experienced financial stressors and higher levels of financial anxiety during COVID had higher levels of debt holdings than those who did not have such experiences. In contrast, there was a negative association between financial literacy and debt holdings, suggesting that as objective financial knowledge and perceived financial capability increased, the number of debt types held decreased. Additionally, when considering age differences, individuals in the young (e.g., MZ generation) and middle (e.g., Gen-Xer) age groups reported holding more debt types than those in the older (e.g., Boomer/silent generation) age group.
Results of the study also revealed that credit card debt, automobile debt, and medical debt were negatively associated with financial satisfaction, whereas mortgage and student loan debt were positively associated with financial satisfaction. This study further found that, compared to those in the older age group, individuals in the young age group had higher levels of financial satisfaction, while individuals in the middle age group had lower levels of financial satisfaction. Importantly, the findings of this thesis can add to the current literature regarding what role age plays in the type of debt utilized at different periods of the life cycle to inform new financial and debt management programs for financial practitioners aimed at increasing financial satisfaction.

description: We provide estimates of volcanism versus time for planets with Earth-like composition and masses from 0.25 to 25 times Earth, as a step toward predicting atmospheric mass on extrasolar rocky planets. Volcanism requires melting of the silicate mantle. We use a thermal evolution model, calibrated against Earth, in combination with standard melting models, to explore the dependence of convection-driven decompression mantle melting on planet mass. Here we show that (1) volcanism is likely to proceed on massive planets with plate tectonics over the main-sequence lifetime of the parent star; (2) crustal thickness (and melting rate normalized to planet mass) is weakly dependent on planet mass; (3) stagnant lid planets live fast (they have higher rates of melting than their plate tectonic counterparts early in their thermal evolution) but die young (melting shuts down after a few Gyr); (4) plate tectonics may not operate on high mass planets because of the production of buoyant crust which is difficult to subduct; and (5) melting is necessary but insufficient for efficient volcanic degassing - volatiles partition into the earliest, deepest melts, which may be denser than the residue and sink to the base of the mantle on young, massive planets. Magma must also crystallize at or near the surface, and the pressure of overlying volatiles must be fairly low, if volatiles are to reach the surface. If volcanism is detected in the Tau Ceti system, and tidal forcing can be shown to be weak, this would be evidence for plate tectonics.

description: Turbulence of scroll waves is a sort of spatio-temporal chaos that exists in three-dimensional excitable media. Cardiac tissue and the Belousov-Zhabotinsky reaction are examples of such media. In cardiac tissue, chaotic behaviour is believed to underlie fibrillation which, without intervention, precedes cardiac death. In this study we investigate suppression of the turbulence using stimulation of two different types, "modulation of excitability" and "extra transmembrane current". With cardiac defibrillation in mind, we used a single pulse as well as repetitive extra current with both constant and feedback controlled frequency. We show that turbulence can be terminated using either a resonant modulation of excitability or a resonant extra current. The turbulence is terminated with much higher probability using a resonant frequency perturbation than a non-resonant one. Suppression of the turbulence using a resonant frequency is up to fifty times faster than using a non-resonant frequency, in both the modulation of excitability and the extra current modes. We also demonstrate that resonant perturbation requires strength one order of magnitude lower than that of a single pulse, which is currently used in clinical practice to terminate cardiac fibrillation. Our results provide a robust method of controlling complex chaotic spatio-temporal processes. Resonant drift of spiral waves has been studied extensively in two dimensions, however, these results show for the first time that it also works in three dimensions, despite the complex nature of the scroll wave turbulence.

description: Existing methods for testing DNNs solve the oracle problem by constraining the raw features (e.g. image pixel values) to be within a small distance of a dataset example for which the desired DNN output is known. But this limits the kinds of faults these approaches are able to detect. In this paper, we introduce a novel DNN testing method that is able to find faults in DNNs that other methods cannot. The crux is that, by leveraging generative machine learning, we can generate fresh test inputs that vary in their high-level features (for images, these include object shape, location, texture, and colour). We demonstrate that our approach is capable of detecting deliberately injected faults as well as new faults in state-of-the-art DNNs, and that in both cases, existing methods are unable to find these faults.

description: The Bowen-York family of spinning black hole initial data depends essentially on one, positive, free parameter. The extreme limit corresponds to making this parameter equal to zero. This choice represents a singular limit for the constraint equations. We prove that in this limit a new solution of the constraint equations is obtained. These initial data have similar properties to the extreme Kerr and Reissner-Nordstrom black hole initial data. In particular, in this limit one of the asymptotic ends changes from asymptotically flat to cylindrical. The existence proof is constructive, we actually show that a sequence of Bowen-York data converges to the extreme solution.

description: A rich variety of specific multidomain textures recently observed in antiferromagnetically coupled multilayers with perpendicular anisotropy include regular (equilibrium) multidomain states as well as different types of topological magnetic defects. Within a phenomenological theory we have classified and analyzed the possible magnetic defects in the antiferromagnetic ground state and determine their structures. We have derived the optimal sizes of the defects as functions of the antiferromagnetic exchange, the applied magnetic field, and geometrical parameters of the multilayer. The calculated magnetic phase diagrams show the existence regions for all types of magnetic defects. Experimental investigations of the remanent states (observed after different magnetic pre-history) in [Co/Pt]/Ru multilayers with wedged Co layers reveal a corresponding succession of different magnetic defect domain types.

description: We characterize the local (2-kpc sized) environments of Type Ia, II, and Ib/c supernovae (SNe) that have recently occurred in nearby ($d\lesssim50$ Mpc) galaxies. Using ultraviolet (UV, from GALEX) and infrared (IR, from WISE) maps of 359 galaxies and a sample of 472 SNe, we measure the star formation rate surface density ($Σ_{\rm SFR}$) and stellar mass surface density ($Σ_\star$) in a 2-kpc beam centered on each SN site. We show that core-collapse SNe are preferentially located along the resolved galactic star-forming main sequence, whereas Type Ia SNe are extended to lower values of $Σ_{\rm SFR}$ at fixed $Σ_\star$, indicative of locations inside quiescent galaxies or quiescent regions of galaxies. We also test how well the radial distribution of each SN type matches the radial distributions of UV and IR light in each host galaxy. We find that, to first order, the distributions of all types of SNe mirror that of both near-IR light (3.4 and 4.5 microns, tracing the stellar mass distribution) and mid-IR light (12 and 22 microns, tracing emission from hot, small grains), and also resemble our best-estimate $Σ_{\rm SFR}$. All types of SNe appear more radially concentrated than the UV emission of their host galaxies. In more detail, the distributions of Type II SNe show small statistical differences from that of near-IR light. We attribute this overall structural uniformity to the fact that within any individual galaxy, $Σ_{\rm SFR}$ and $Σ_\star$ track one another well, with variations in $Σ_{\rm SFR}/Σ_\star$ most visible when comparing between galaxies.

Mapping the QCD Phase Transition with Accreting Compact Stars

Subjects: subject: Astrophysics (astro-ph)

description: We discuss an idea for how accreting millisecond pulsars could contribute to the understanding of the QCD phase transition in the high-density nuclear matter equation of state (EoS). It is based on two ingredients, the first one being a ``phase diagram'' of rapidly rotating compact star configurations in the plane of spin frequency and mass, determined with state-of-the-art hybrid equations of state, allowing for a transition to color superconducting quark matter. The second is the study of spin-up and accretion evolution in this phase diagram. We show that the quark matter phase transition leads to a characteristic line in the Omega-M plane, the phase border between neutron stars and hybrid stars with a quark matter core. Along this line a change in the pulsar's moment of inertia entails a waiting point phenomenon in the accreting millisecond X-ray pulsar (AMXP) evolution: most of these objects should therefore be found along the phase border in the Omega-M plane, which may be viewed as the AMXP analog of the main sequence in the Hertzsprung-Russell diagram for normal stars. In order to prove the existence of a high-density phase transition in the cores of compact stars we need population statistics for AMXP's with sufficiently accurate determination of their masses and spin frequencies.

Rapid expansion of red giant stars during core helium flash by waves propagation to the envelope and implications to exoplanets

description: We assume that the strong convection during core helium flash of low mass red giant branch (RBG) stars excite waves that propagate to the envelope, and find that the energy that these waves deposit in the envelope causes envelope expansion and brightening. We base our assumption and the estimate of the wave energy on studies that explored such a process due to the vigorous core convection of massive stars just before they experience a core collapse supernova explosion. Using the stellar evolutionary code MESA we find that the wave energy causes an expansion within few years by tens to hundreds solar radii. Despite the large brightening, we expect the increase in radius and luminosity to substantially enhance mass loss rate and dust formation. The dust shifts the star to become much redder (to the infrared), and the star might actually become fainter in the visible. The overall appearance is of a faint red transient event that lasts for months to few years. We suggest that in some cases envelope expansion might lead stars that are about to leave the RGB to engulf exoplanets. The extended envelope has a smaller binding energy to a degree that allows planets of several Jupiter masses or more and brown dwarfs to survive the common envelope evolution. We suggest this scenario to account for the planet orbiting the white dwarf (WD) WD1856+534 (TIC 267574918) and for the WD - brown dwarf binary system ZTFJ003855.0+203025.5.

description: Development of a guided occlusive biodegradable membrane with controlled morphology in order to restrict the ingrowth of epithelial cells is still a challenge in dental tissue engineering. A bilayer membrane with a non-porous upper layer (polyurethane) and porous lower layer (polycaprolactone and bioactive glass composite) with thermoelastic properties to sustain surgery treatment was developed by lyophilization. Morphology, porosity, and layers attachment were controlled by using the multi-solvent system. In vitro and in vivo biocompatibility, cell attachment, and cell proliferation were analyzed by immunohistochemistry and histology. The cell proliferation rate and cell attachment results showed good biocompatibility of both surfaces, though cell metabolic activity was better on the polycaprolactone-bioactive glass surface. Furthermore, the cells were viable, adhered, and proliferated well on the lower porous bioactive surface, while non-porous polyurethane surface demonstrated low cell attachment, which was deliberately designed and a pre-requisite for guided tissue regeneration/guided bone regeneration membranes. In addition, in vivo studies performed in a rat model for six weeks revealed good compatibility of membranes. Histological analysis (staining with hematoxylin and eosin) indicated no signs of inflammation or accumulation of host immune cells. These results suggested that the fabricated biocompatible bilayer membrane has the potential for use in periodontal tissue regeneration.

description: Much of the progress in contemporary NLP has come from learning representations, such as masked language model (MLM) contextual embeddings, that turn challenging problems into simple classification tasks. But how do we quantify and explain this effect? We adapt general tools from computational learning theory to fit the specific characteristics of text datasets and present a method to evaluate the compatibility between representations and tasks. Even though many tasks can be easily solved with simple bag-of-words (BOW) representations, BOW does poorly on hard natural language inference tasks. For one such task we find that BOW cannot distinguish between real and randomized labelings, while pre-trained MLM representations show 72x greater distinction between real and random labelings than BOW. This method provides a calibrated, quantitative measure of the difficulty of a classification-based NLP task, enabling comparisons between representations without requiring empirical evaluations that may be sensitive to initializations and hyperparameters. The method provides a fresh perspective on the patterns in a dataset and the alignment of those patterns with specific labels.

An exploration of existential phenomenology as an approach to curriculum evaluation
Creators: name: Rothe, John Peter
Publisher: name: University of British Columbia
Year: 2010

description: This study explores the conceptualization of an approach for evaluating social studies curriculum that is grounded in the interpretive paradigm. The approach called existential phenomenology, grew out of a critical examination of the assumptions and practicalities of contemporary evaluation techniques, existential phenomenological literature and ethnographic research. It reflects implicit concerns recently found in curriculum, evaluation and sociology discourse. Existential phenomenological inquiry assumes that individual's assign personal meanings to different situations in which they are immersed. Meanings that are usually hidden or taken-for-granted by members of the everyday world are made problematic in this study. For example, as I write the abstract to the thesis I give it meaning reflecting the reason that I write it. The meanings I assign influence how I write. Once this theme is expanded to a social studies situation, the meanings students and teachers assign to various classroom phenomena are seen to play a significant role in "how they do what they do". Situational meanings are grounded in the basic existential phenomenological assumption that when a teacher or student chooses a project (seeing an act as complete), he has explainable reasons for having made a choice in relation to his project. The reasons suggest meanings a student or teacher assigns to a dimension of social studies. Information gathering procedures undertaken at Z Senior Secondary School are outlined. Ethnographic techniques such as interviewing, interpreting and describing were applied within the evaluatee-as-co-evaluator framework. Precise accounts of planning, greeting, entering, interviewing, verifying, interpreting and describing are provided. Transcribed interviews are included to illustrate conversations that occurred in interview sessions. Interpretations based on "passive, immediate, responsible and transcendent areas of being" indicate that students and teachers base their everyday classroom activities on hidden meanings. Once meanings were uprooted, described and made available to teachers and students, both groups took time to reflect upon them. Through discussions between participants and.myself, teachers and students critically questioned their assumptions and perspectives, and projected desire for change. They proposed that existential phenomenological research be expanded and that the results be forwarded to decision-makers.

description: The Birnbaum-Saunders regression model is commonly used in reliability studies. We address the issue of performing inference in this class of models when the number of observations is small. We show that the likelihood ratio test tends to be liberal when the sample size is small, and we obtain a correction factor which reduces the size distortion of the test. The correction makes the error rate of he test vanish faster as the sample size increases. The numerical results show that the modified test is more reliable in finite samples than the usual likelihood ratio test. We also present an empirical application.

description: Recent advances in the high sensitivity spectroscopy have made it possible, in combination with accurate theoretical predictions, to observe for the first time very weak electric quadrupole transitions in a polar polyatomic molecule of water. Here we present accurate theoretical predictions of the complete quadrupole ro-vibrational spectrum of a non-polar molecule CO$_2$, important in atmospheric and astrophysical applications. Our predictions are validated by recent cavity enhanced absorption spectroscopy measurements and are used to assign few weak features in the recent ExoMars ACS MIR spectroscopic observations of the martian atmosphere. Predicted quadrupole transitions appear in some of the mid-infrared CO$_2$ and water vapor transparency regions, making them important for detection and characterization of the minor absorbers in water- and CO$_2$-rich environments, such as present in the atmospheres of Earth, Venus and Mars.

Open charm measurement with HFT at STAR

subject: FOS: Physical sciences

description: Thermalization is one of the key questions in understanding the matter created in Au+Au collisions at RHIC. Heavy-flavor quark collectivity could be used to indicate the degree of thermalization of the light-flavor quarks. Heavy quark energy loss could give important information on color charge density of the medium. Direct reconstruction of open charm hadrons is essential for these measurements. The Heavy Flavor Tracker (HFT) is a proposed upgrade of the STAR experiment. Full GEANT simulation of tracking with HFT was performed, showing its excellent capability to reconstruct open charm hadrons in broad p_T range at midrapidity. Estimated errors on measurement of D0 meson v_2 and R_{CP} are presented.

Einstein-Gauss-Bonnet gravity with rational nonlinear electrodynamics
Creators: name: Kruglov, S. I.

description: We obtain an exact spherically symmetric and magnetically charged black hole solution in 4D Einstein-Gauss-Bonnet gravity coupled with rational nonlinear electrodynamics. The thermodynamics of our model is studied. We calculate the Hawking temperature and the heat capacity of the black hole. The phase transitions occur in the point where the Hawking temperature possesses an extremum. We show that black holes are thermodynamically stable at some range of event horizon radii when the heat capacity is positive. The logarithmic correction to the Bekenstein-Hawking entropy is obtained.

description: The Max-Cut polytope appears in the formulation of many difficult combinatorial optimization problems. These problems can also be formulated as optimization problems over the so-called trigonometric approximation which possesses an algorithmically accessible description but is not convex. Hirschfeld conjectured that this trigonometric approximation is star-like. In this article, we provide a proof of this conjecture.

OBSTETRIC EARLY WARNING SYSTEM
Creators: name: McGolrick, Alana
Publisher: name: Zenodo
Year: 2018

description: Despite access to the world’s leading healthcare, the United States has not made a significant impact on obstetrical patient safety. The Joint Commission data demonstrates that maternal adverse events such as inaccurate assessment, misinterpretation of fetal and uterine activity, and/or late communication of a patient’s clinical picture, leads to severe maternal and neonatal morbidity or death. An obstetric early warning system trigger tool, based on unique maternal physiological parameters, can be instrumental in identifying patients before negative consequences or deterioration occurs. The purpose of this project was to develop an obstetric early warning system trigger tool for the intrapartum patient in the labor and delivery setting, utilizing specific physiological parameters that may indicate a potential emergent situation. A primary literature search was conducted, and the PDSA quality improvement framework was applied, allowing for multiple applications through the project. The final product, was a subject matter expert evaluated trigger tool, now prepared for simulation testing.

Anisotropic fluid dynamics in the early stage of relativistic heavy-ion collisions
Creators: name: Florkowski, Wojciech
Publisher: name: arXiv
Year: 2008
Subjects: subject: Nuclear Theory (nucl-th)

description: A formalism for anisotropic fluid dynamics is proposed. It is designed to describe boost-invariant systems with anisotropic pressure. Such systems are expected to be produced at the early stages of relativistic heavy-ion collisions, when the timescales are too short to achieve equal thermalization of transverse and longitudinal degrees of freedom. The approach is based on the energy-momentum and entropy conservation laws, and may be regarded as a minimal extension of the boost-invariant standard relativistic hydrodynamics of the perfect fluid. We show how the formalism may be used to describe the isotropization of the system (the transition from the initial state with no longitudinal pressure to the final state with equal longitudinal and transverse pressure).

description: Regression is one of the most commonly used statistical techniques. However, testing regression systems is a great challenge because of the absence of test oracle in general. In this paper, we show that Metamorphic Testing is an effective approach to test multiple linear regression systems. In doing so, we identify intrinsic mathematical properties of linear regression, and then propose 11 Metamorphic Relations to be used for testing. Their effectiveness is examined using mutation analysis with a range of different regression programs. We further look at how the testing could be adopted in a more effective way. Our work is applicable to examine the reliability of predictive systems based on regression that has been widely used in economics, engineering and science, as well as of the regression calculation manipulated by statistical users.
