title: Effects of Endurance Exercise and Progesterone Levels on Atrial Fibrillation Inducibility in a Transgenic Goat Model Exhibiting Atrial Fibrosis
Creators: name: Regouski, Misha
Publisher: name: Utah State University
Year: 2023

description: The normal functioning of the heart involves a series of events that result in a coordinated muscle contraction, enabling blood circulation throughout the body. Atrial fibrillation (AF) is a prevalent cardiac arrhythmia characterized by irregular contractions of the atria, the smaller upper chambers of the heart. While the exact mechanisms behind AF are not fully understood, multiple factors contribute to its development, including fibrosis. Fibrosis, the development of fibrous connective tissue in the heart, disrupts normal electrical activity, thereby perpetuating the arrhythmia. In our research, we have created a transgenic (TG) goat model that exhibits atrial fibrosis and experiences sustained episodes of AF. With this model, we conducted several studies to better understand the baseline characteristics of the model and explore the effects of specific environmental triggers.
Initially, we compared the AF burden in the TG model to a control group consisting of wild-type (WT) animals. Additionally, we examined inflammatory markers and levels of selected target genes at the cellular and tissue level in these animals to identify any potential contributors to AF development. Subsequently, we designed an exercise study to investigate the impact of endurance exercise on animals with AF. Interestingly, we observed an increase in inducible AF episodes in both TG and WT goats during the study, with a return to near-baseline levels by the third month. Furthermore, we explored the influence of pregnancy on AF inducibility in TG and WT goats. We noted a decrease in an inducible AF in all animals during pregnancy, followed by a significant increase immediately after parturition. Upon concluding the pregnancy study, we developed additional experiments to examine the role of progesterone (P4) in AF development. Throughout our studies, we observed a potential protective effect of P4 on arrhythmia, as withdrawal of the hormone increased levels of AF.
Through our investigations using a large animal TG model of atrial fibrosis, we have identified several physiological stressors and their impact on the development of AF. These findings contribute to a better understanding of AF pathologies and may guide future research and potential therapeutic interventions.

Distance to M87 as the Mode of the Modulus Distribution

description: de Grijs and Bono (ApJS 2020, 246, 3) compiled a list of distances to M87 from the literature published in the last 100 years. They reported the arithmetic mean of the three most stable tracers (Cepheids, tip of the red giant branch, and surface brightness fluctuations). The arithmetic mean is one of the measures of central tendency of a distribution; others are the median and mode. The three do not align for asymmetric distributions, which is the case for the distance moduli $μ_0$ to M87. I construct a kernel density distribution of the set of $μ_0$ and estimate the recommended distance to M87 as its mode, obtaining $μ_0 = \left(31.06~\pm~0.001\,\textrm{(statistical)}\,^{+0.04}_{-0.06}\,\textrm{(systematic)}\right)$~mag, corresponding to \linebreak $D=16.29^{+0.30}_{-0.45}$~Mpc, which yields uncertainties smaller than those associated with the mean and median.

description: Computer Technology has Revolutionized Science. This has motivated scientists to develop mathematical model to simulate salient features of Physical universe. These models can approximate reality at many levels of scale such as atomic nucleus, Earth's biosphere & weather/climate assessment. If the computer power is greater, the greater will be the accuracy in approximation i.e. close will be the approximation to the reality. The speed of the computer required for solution of such problems require computers with processing power of teraflops to Pets flops speed.. The way to speed up the computation is to "parallelize" it. One of the approach is to use multimillion dollar Supercomputer or use Computational Grid (which is also called poor man's supercomputer) having geographically distributed resources e.g. SETI@home (Used to detect radio waves emitted by intelligent civilizations outside earth) has 4.6 million participants computers. There are many alternatives tools available to achieve this goal like Globus Toolkit, Entropia, Legion, BOINC etc but they are mainly based on Linux platform. As majority of the computers available are windows based, so it will be easy to develop a larger network of computers which will use the free cycles of the computer to solve the complex problem at window platform. Nimble@ITCEcnoGrid has been developed. It includes the feature of Inter Thread Communication which is missing in any of the toolkits available. Nimble@ITCEcnoGrid Framework (A Fast Grid with Inter-thread communication with Economic Based Policy) was tested for computation of 'PI' up to 120 decimal points. Encouraged by the speed the same system has been utilized to computes the Momentum, Thermodynamics and Continuity equations for the Weather Forecasting using the Windows based Desktop computers.

description: The Canada-France-Hawaii Legacy Survey (CFHTLS) comprising about 25 000 MegaCam images was data mined to search for serendipitous encounters of known Near Earth Asteroids (NEAs) and Potentially Hazardous Asteroids (PHAs). A total of 143 asteroids (109 NEAs and 34 PHAs) were found on 508 candidate images which were field corrected and measured carefully, and their astrometry was reported to Minor Planet Centre. Both recoveries and precoveries (apparitions before discovery) were reported, including data for 27 precovered asteroids (20 NEAs and 7 PHAs) and 116 recovered asteroids (89 NEAs and 27 PHAs). Our data prolonged arcs for 41 orbits at first or last opposition, refined 35 orbits by fitting data taken at one new opposition, recovered 6 NEAs at their second opposition and allowed us to ameliorate most orbits and their Minimal Orbital Intersection Distance (MOID), an important parameter to monitor for potential Earth impact hazard in the future.

title: Navigating Roadblocks in Utah's Path Towards Curbing Greenhouse Gas Emissions
Creators: name: Fletcher, Emily K.
Publisher: name: Utah State University
Year: 2023

description: In places where discussions about climate change have become highly political and divided, community groups have attempted to connect rival political parties by focusing on improving air quality. This topic is often less politically charged. The effects of climate change have been disproportionately felt by marginalized communities around the world. In the west side of the Salt Lake Valley, many communities are more likely to experience the negative consequences of a drying lake, a problem that Utah and other regions are currently facing, compared to others in the valley. This research focuses on the individuals who have signed the Utah Climate and Clean Air Compact, a public attempt to bring together political parties in a conservative state to address air quality issues in Utah. The state is facing challenges such as rapid population growth, rising temperatures, and prolonged drought conditions. Despite some prominent leaders publicly endorsing this Compact, progress towards improving air quality and addressing climate change has been slow in Utah. It is also unclear if these leaders are considering the unequal impacts that marginalized communities may face. However, there have been some efforts made since the Compact's publication and signing that indicate minor successes in the state. To understand the perceived obstacles to taking action on climate change and potential solutions, I conducted semi-structured interviews with community leaders, business representatives, and other individuals who signed the Compact. I also analyzed documents such as interviews and opinion pieces focusing on or written by the signatories of the Compact. The first study revealed that population growth and political disagreements are the most common barriers reported by leaders in Utah. According to these leaders, the key to addressing air quality and climate issues lies in working together across party lines, even though significant progress has not been made so far. The second study found that although most leaders express concern about the negative effects of the drying Great Salt Lake, they tend to focus on the entire valley rather than prioritizing the needs of the most vulnerable residents. They also do not ensure that these communities have a say in decisions related to water use and air quality policies, signaling that major changes to include these communities must be made in the planning and mitigation process for these issues.

description: (ABRIDGED) We present here the results from new Very Long Baseline Array observations at 1.6 and 5 GHz of 19 galaxies of a complete sample of 21 UGC FRI radio galaxies. New Chandra data of two sources, viz., UGC00408 and UGC08433, are combined with the Chandra archival data of 13 sources. The 5 GHz observations of ten "core-jet" sources are polarization-sensitive, while the 1.6 GHz observations constitute second epoch total intensity observations of nine "core-only" sources. Polarized emission is detected in the jets of seven sources at 5 GHz, but the cores are essentially unpolarized, except in M87. Polarization is detected at the jet edges in several sources, and the inferred magnetic field is primarily aligned with the jet direction. This could be indicative of magnetic field "shearing" due to jet-medium interaction, or the presence of helical magnetic fields. The jet peak intensity $I_ν$ falls with distance $d$ from the core, following the relation, $I_ν\propto d^a$, where $a$ is typically -1.5. Assuming that adiabatic expansion losses are primarily responsible for the jet intensity "dimming", two limiting cases are considered: [1] the jet has a constant speed on parsec-scales and is expanding gradually such that the jet radius $r\propto d^0.4$; this expansion is however unobservable in the laterally unresolved jets at 5 GHz, and [2] the jet is cylindrical and is accelerating on parsec-scales. Accelerating parsec-scale jets are consistent with the phenomenon of "magnetic driving" in Poynting flux dominated jets. Chandra observations of 15 UGC FRIs detect X-ray jets in nine of them. The high frequency of occurrence of X-ray jets in this complete sample suggests that they are a signature of a ubiquitous process in FRI jets.

description: In the last years, Google's PageRank optimization problems have been extensively studied. In that case, the ranking is given by the invariant measure of a stochastic matrix. In this paper, we consider the more general situation in which the ranking is determined by the Perron eigenvector of a nonnegative, but not necessarily stochastic, matrix, in order to cover Kleinberg's HITS algorithm. We also give some results for Tomlin's HOTS algorithm. The problem consists then in finding an optimal outlink strategy subject to design constraints and for a given search engine. We study the relaxed versions of these problems, which means that we should accept weighted hyperlinks. We provide an efficient algorithm for the computation of the matrix of partial derivatives of the criterion, that uses the low rank property of this matrix. We give a scalable algorithm that couples gradient and power iterations and gives a local minimum of the Perron vector optimization problem. We prove convergence by considering it as an approximate gradient method. We then show that optimal linkage stategies of HITS and HOTS optimization problems verify a threshold property. We report numerical results on fragments of the real web graph for these search engine optimization problems.

The Polarization Properties of Inverse Compton Emission and Implications for Blazar Observations with the GEMS X-Ray Polarimeter

Year: 2011
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: NASA's Small Explorer Mission GEMS (Gravity and Extreme Magnetism SMEX), scheduled for launch in 2014, will have the sensitivity to detect and measure the linear polarization properties of the 0.5 keV and 2-10 keV X-ray emission of a considerable number of galactic and extragalactic sources. The prospect of sensitive X-ray polarimetry justifies a closer look at the polarization properties of the basic emission mechanisms. In this paper, we present analytical and numerical calculations of the linear polarization properties of inverse Compton scattered radiation. We describe a generally applicable formalism that can be used to numerically compute the polarization properties in the Thomson and Klein-Nishina regimes. We use the code to perform for the first time a detailed comparison of numerical results and the earlier analytical results derived by Bonometto et al. (1970) for scatterings in the Thomson regime. Furthermore, we use the numerical formalism to scrutinize the polarization properties of synchrotron self-Compton emission, and of inverse Compton radiation emitted in the Klein-Nishina regime. We conclude with a discussion of the scientific potential of future GEMS observations of blazars. The GEMS mission will be able to confirm the synchrotron origin of the low-energy emission component from high frequency peaked BL Lac objects. Furthermore, the observations have the potential to decide between a synchrotron self-Compton and external-Compton origin of the high-energy emission component from flat spectrum radio quasars and low frequency peaked BL Lac objects.

description: We have found that intensity $I$ and circular polarization degree $ρ$ of the edge photoluminescence, excited in GaAsN alloys by circularly polarized light at room temperature, grow substantially in the longitudinal magnetic field $B$ of the order of 1\,kG. This increase depends on the intensity of pumping and, in the region of weak or moderate intensities, may reach a twofold value. In two-charge-state model, which considers spin-dependent recombination of spin-oriented free electrons on deep paramagnetic centers, we included the magnetic-field suppression of spin relaxation of the electrons bound on centers. The model describes qualitatively the rise of $ρ$ and $I$ in a magnetic field under different pump intensities. Experimental dependences $ρ(B)$ and $I(B)$ are shifted with respect to zero of the magnetic field by a value of $\sim$170\,Gauss, while the direction of the shift reverses with change of the sign of circular polarization of pumping. As a possible cause of the discovered shift we consider the Overhauser field, arising due to the hyperfine interaction of an electron bound on a center with nuclei of the crystal lattice in the vicinity of the center.

description: Due to the ultrarelativistic velocity of the expanding "fireshell" (Lorentz gamma factor γ\sim 10^2 - 10^3), photons emitted at the same time from the fireshell surface do not reach the observer at the same arrival time. In interpreting Gamma-Ray Bursts (GRBs) it is crucial to determine the properties of the EQuiTemporal Surfaces (EQTSs): the locus of points which are source of radiation reaching the observer at the same arrival time. In the current literature this analysis is performed only in the latest phases of the afterglow. Here we study the distribution of the GRB bolometric luminosity over the EQTSs, with special attention to the prompt emission phase. We analyze as well the temporal evolution of the EQTS apparent size in the sky. We use the analytic solutions of the equations of motion of the fireshell and the corresponding analytic expressions of the EQTSs which have been presented in recent works and which are valid for both the fully radiative and the adiabatic dynamics. We find the novel result that at the beginning of the prompt emission the most luminous regions of the EQTSs are the ones closest to the line of sight. On the contrary, in the late prompt emission and in the early afterglow phases the most luminous EQTS regions are the ones closest to the boundary of the visible region. This transition in the emitting region may lead to specific observational signatures, i.e. an anomalous spectral evolution, in the rising part or at the peak of the prompt emission. We find as well an expression for the apparent radius of the EQTS in the sky, valid in both the fully radiative and the adiabatic regimes. Such considerations are essential for the theoretical interpretation of the prompt emission phase of GRBs.

Truncated Configuration Interaction expansions as solvers for correlated quantum impurity models and dynamical mean field theory

description: The development of polynomial cost solvers for correlated quantum impurity models, with controllable errors, is a central challenge in quantum many-body physics, where these models find applications ranging from nano-science to the dynamical mean-field theory (DMFT). Here we describe how configuration interaction (CI) approximations to exact diagonalization (ED) may be used as solvers in DMFT. CI approximations retain the main advantages of ED, such as the ability to treat general interactions and off-diagonal hybridizations and to obtain real spectral information, but are of polynomial cost. Furthermore, their errors can be controlled by monitoring the convergence of physical quantities as a function of the CI hierarchy. Using benchmark DMFT applications, such as single-site DMFT of the 1D Hubbard model and $2\times 2$ cluster DMFT of the 2D Hubbard model, we show that CI approximations allow us to obtain near-exact ED results for a tiny fraction of the cost. This is true over the entire range of interaction strengths including "difficult" regimes, such as in the pseudogap phase of the 2D Hubbard model. We use the ability of CI approximations to treat large numbers of orbitals to demonstrate convergence of the bath representation in the $2\times 2$ cluster DMFT using a 24 bath orbital representation. CI approximations thus form a promising route to extend ED to problems that are currently difficult to study using other solvers such as continuous-time quantum Monte Carlo, including impurity models with large numbers of orbitals and general interactions.

description: Recent infrared (IR) observations of freshly-formed dust in supernova remnants (SNRs) have yielded significantly lower dust masses than predicted by theoretical models and measured from high redshift observations. The Crab Nebula's pulsar wind is thought to be sweeping up freshly-formed supernova (SN) dust along with the ejected gas. The evidence for this dust was found in the form of an IR excess in the integrated spectrum of the Crab and in extinction against the synchrotron nebula that revealed the presence of dust in the filament cores. We present the first spatially resolved emission spectra of dust in the Crab Nebula acquired with the Infrared Spectrograph aboard the Spitzer Space Telescope. The IR spectra are dominated by synchrotron emission and show forbidden line emission from from S, Si, Ne, Ar, O, Fe, and Ni. We derived a synchrotron spectral map from the 3.6 and 4.5 microns images, and subtracted this contribution from our data to produce a map of the residual continuum emission from dust. The dust emission appears to be concentrated along the ejecta filaments and is well described by an amorphous carbon or silicate grain compositions. We find a dust temperature of 55+/- 4 K for silicates and 60 +/- 7 K for carbon grains. The total estimated dust mass is 0.0012-0.012 solar masses, well below the theoretical dust yield predicted for a core-collapse supernova. Our grain heating model implies that the dust grain radii are relatively small, unlike what is expected for dust grains formed in a Type IIP SN.

description: Wenn in der deutschsprachigen Schweiz Kinder mit Französisch als Herkunftssprache den obligatorischen schulischen Französischunterricht ab der Primarstufe besuchen, ist aufgrund ihrer bereits vorhandenen Sprachkenntnisse eine verstärkte Binnendifferenzierung nötig. Im vom Bundesamt für Kultur unterstützten Projekt Français pour les bilingues (Teilprojekt 3) werden Lernmaterialien für ein adäquates Förderprogramm entwickelt und mit Praxistestklassen erprobt. Die entwickelten Lerneinheiten werden ausserdem einer fremdsprachendidaktischen Expertise unterzogen. Der Beitrag zeigt, wie die empirisch gewonnenen Erkenntnisse in die Überarbeitung der Materialien einfliessen, und nennt wesentliche Aspekte einer integrativen Förderung, die auf der einen Seite die französisch-deutsch bilingualen Kinder als Gruppe erfasst und auf der anderen Seite diese heterogene Gruppe wiederum differenzierend behandelt, wodurch Binnendifferenzierung bis hin zur Individualisierung notwendig ist.

description: We study spin-dependent transport through a spin diode in the presence of spin-flip by means of reduced density matrix approach. The current polarization and the spin accumulation are computed and influence of spin-flip on the current polarization is also analyzed. Analytical relations for the current polarization and the spin accumulation are obtained as a function of polarization of ferromagnetic lead and the spin-flip rate. It is observed that the current polarization becomes zero under fast spin-flip and the spin accumulation decreases up to %85 when the time of spin-flip is equal to the tunneling time. It is also observed that the current polarization increases linearly when the dot is singly occupied, whereas its behavior is more complicated when the dot is doubly occupied.

description: We present differential conductance measurements of Cobalt / Cobalt-Oxide / Indium planar junctions, 500nm x 500nm in size. The junctions span a wide range of barriers, from very low to a tunnel barrier. The characteristic conductance of all the junctions show a V-shape structure at low bias instead of the U-shape characteristic of a s-wave order parameter. The bias of the conductance peaks is, for all junctions, larger than the gap of indium. Both properties exclude pure s-wave pairing. The data is well fitted by a model that assumes the coexistence of s-wave singlet and equal spin p-wave triplet fluids. We find that the values of the s-wave and p-wave gaps follow the BCS temperature dependance and that the amplitude of the s-wave fluid increases with the barrier strength.

Hermitian scattering behavior for the non-Hermitian scattering center

description: We study the scattering problem for the non-Hermitian scattering center, which consists of two Hermitian clusters with anti-Hermitian couplings between them. Counterintuitively, it is shown that it acts as a Hermitian scattering center, satisfying $|r| ^{2}+|t| ^{2}=1$, i.e., the Dirac probability current is conserved, when one of two clusters is embedded in the waveguides. This conclusion can be applied to an arbitrary parity-symmetric real Hermitian graph with additional PT-symmetric potentials, which is more feasible in experiment. Exactly solvable model is presented to illustrate the theory. Bethe ansatz solution indicates that the transmission spectrum of such a cluster displays peculiar feature arising from the non-Hermiticity of the scattering center.

Multi-pollutant personal exposure
Automated time-activity classification

description: BACKGROUND: Air pollution epidemiology has primarily relied on measurements from fixed outdoor air quality monitoring stations to derive population-scale exposure. Characterisation of individual time-activity-location patterns is critical for accurate estimations of personal exposure and dose because pollutant concentrations and inhalation rates vary significantly by location and activity. METHODS: We developed and evaluated an automated model to classify major exposure-related microenvironments (home, work, other static, in-transit) and separated them into indoor and outdoor locations, sleeping activity and five modes of transport (walking, cycling, car, bus, metro/train) with multidisciplinary methods from the fields of movement ecology and artificial intelligence. As input parameters, we used GPS coordinates, accelerometry, and noise, collected at 1 min intervals with a validated Personal Air quality Monitor (PAM) carried by 35 volunteers for one week each. The model classifications were then evaluated against manual time-activity logs kept by participants. RESULTS: Overall, the model performed reliably in classifying home, work, and other indoor microenvironments (F1-score>0.70) but only moderately well for sleeping and visits to outdoor microenvironments (F1-score=0.57 and 0.3 respectively). Random forest approaches performed very well in classifying modes of transport (F1-score>0.91). We found that the performance of the automated methods significantly surpassed those of manual logs. CONCLUSIONS: Automated models for time-activity classification can markedly improve exposure metrics. Such models can be developed in many programming languages, and if well formulated can have general applicability in large-scale health studies, providing a comprehensive picture of environmental health risks during daily life with readily gathered parameters from smartphone technologies.

title: Using Telehealth to Teach Caregivers Mand Training Using a Speech Generating Device
Creators: name: Jeppson, Sara
Publisher: name: Utah State University

description: Children with ASD often have struggles with social communication and developing a functional vocal output. Alternative and augmentative communication (AAC) can be used in different modes such as speech generating devices (SGDs) to help these individuals develop a vocal output. Caregivers are optimal to aid their children in learning these communication skills. Past studies such as Suberman and Civindini-Motta showed that behavioral skills training (BST) can be effective to teach caregivers communication training using an SGD. The current study aimed to replicate the procedures of Suberman and Civindini-Motta but extended it by adapting the procedures described using telehealth.

description: Several models of flocking have been promoted based on simulations with qualitatively naturalistic behavior. In this paper we provide the first direct application of computational modeling methods to infer flocking behavior from experimental field data. We show that this approach is able to infer general rules for interaction, or lack of interaction, among members of a flock or, more generally, any community. Using experimental field measurements of homing pigeons in flight we demonstrate the existence of a basic distance dependent attraction/repulsion relationship and show that this rule is sufficient to explain collective behavior observed in nature. Positional data of individuals over time are used as input data to a computational algorithm capable of building complex nonlinear functions that can represent the system behavior. Topological nearest neighbor interactions are considered to characterize the components within this model. The efficacy of this method is demonstrated with simulated noisy data generated from the classical (two dimensional) Vicsek model. When applied to experimental data from homing pigeon flights we show that the more complex three dimensional models are capable of predicting and simulating trajectories, as well as exhibiting realistic collective dynamics. The simulations of the reconstructed models are used to extract properties of the collective behavior in pigeons, and how it is affected by changing the initial conditions of the system. Our results demonstrate that this approach may be applied to construct models capable of simulating trajectories and collective dynamics using experimental field measurements of herd movement. From these models, the behavior of the individual agents (animals) may be inferred.

description: Tone Tutorial: the investigator read tone patterns reported in the monograph about tone in Yongning Na (Michaud 2017), which at the time of recording was nearing completion. The consultant was asked to check whether those productions were correct and intelligible way. This was one of several methods for verifying the findings. Thus, this is not phonological elicitation, but a recording of a work session in which the investigator asked the consultant to check whether he realized the tone patterns in a correct and intelligible way. If a pattern was OK, the consultant repeated it. If it was not, she provided a correction. (Part 1 of 3.) This document covers: Table 5.6, Table 5.8, and Table 5.9.

description: A sterile neutrino with a mass around the keV scale could be an interesting candidate for warm dark matter. Although there are several scenarios and production mechanisms known in which such a particle could yield the correct abundance, there are astonishingly few models around that can actually yield an explanation for the appearance of a keV-like scale. We here review three main classes of such mass models for keV sterile neutrino dark matter, based on split seesaw, on L_e - L_μ- L_τ symmetry, and on the Froggatt-Nielsen mechanism, respectively.
