description: The Taiwanese-American Occultation Survey (TAOS) monitors fields of up to ~1000 stars at 5 Hz simultaneously with four small telescopes to detect occultation events from small (~1 km) Kuiper Belt Objects (KBOs). The survey presents a number of challenges, in particular the fact that the occultation events we are searching for are extremely rare and are typically manifested as slight flux drops for only one or two consecutive time series measurements. We have developed a statistical analysis technique to search the multi-telescope data set for simultaneous flux drops which provides a robust false positive rejection and calculation of event significance. In this paper, we describe in detail this statistical technique and its application to the TAOS data set.

title: Premarital Education: Participation, Attitudes, and Relation to Marital Adjustment in a Sample from Northern Utah
Creators: name: Ramboz, Bryan D.
Publisher: name: Utah State University
Year: 2003

description: The purpose of this study was to investigate the attitudes, participation in, and potential effectiveness of premarital education as a vehicle to promote more satisfying marriages. A retrospective survey instrument, including existing measures of religious values, willingness to invest in marriage, and marital satisfaction, was used to gather data to answer research questions related to couples' participation in, and attitudes about premarital education, and their influence on marital adjustment and satisfaction. Information about the amount of Time spent in premarital education, breadth of Topics covered, Training of the provider, and whether or not Testing was performed also was gathered and called Four T's of premarital education. Sample couples were identified by comparing marriage license information to current telephone listings from Cache County, Utah. One hundred forty-five couples returned usable surveys. Statistical analysis revealed that most couples participated in little or no premarital education even though most couples had favorable attitudes towards such marriage preparations. Further, no significant relation was found between participation in any type of premarital education and marital adjustment or satisfaction. Implications for policy and practice are discussed.

description: The anisotropic superconducting state properties in Cu0.03TaS2 have been investigated by magnetization, magnetoresistance, and specific heat measurements. It clearly shows that Cu0.03TaS2 undergoes a superconducting transition at TC = 4.03 K. The obtained superconducting parameters demonstrate that Cu0.03TaS2 is an anisotropic type-II superconductor. Combining specific heat jump = 1.6(4), gap ratio 2/kBTC = 4.0(9) and the estimated electron-phonon coupling constant ~ 0.68, the superconductivity in Cu0.03TaS2 is explained within the intermediate coupling BCS scenario. First-principles electronic structure calculations suggest that copper intercalation of 2H-TaS2 causes a considerable increase of the Fermi surface volume and the carrier density, which suppresses the CDW fluctuation and favors the raise of TC.

description: The union-closed sets conjecture states that in any nonempty union-closed family $\mathcal{F}$ of subsets of a finite set, there exists an element contained in at least a proportion $1/2$ of the sets of $\mathcal{F}$. Using the information-theoretic method, Gilmer \cite{gilmer2022constant} recently showed that there exists an element contained in at least a proportion $0.01$ of the sets of such $\mathcal{F}$. He conjectured that his technique can be pushed to the constant $\frac{3-\sqrt{5}}{2}$ which was subsequently confirmed by several researchers \cite{sawin2022improved,chase2022approximate,alweiss2022improved,pebody2022extension}. Furthermore, Sawin \cite{sawin2022improved} showed that Gilmer's technique can be improved to obtain a bound better than $\frac{3-\sqrt{5}}{2}$, but this new bound is not explicitly given by Sawin. This paper further improves Gilmer's technique to derive new bounds in the optimization form for the union-closed sets conjecture. These bounds include Sawin's improvement as a special case. By providing cardinality bounds on auxiliary random variables, we make Sawin's improvement computable, and then evaluate it numerically which yields a bound around $0.38234$, slightly better than $\frac{3-\sqrt{5}}{2}\approx0.38197$. }

title: Predictors of 1997 Chapter 13 Bankruptcy Completion and Dismissal Rates in Utah
Creators: name: Evans, David A.
Publisher: name: Utah State University
Year: 2004

description: The purpose of this study was two-fold. The first intention was to identify a group of debtor characteristics that predicted discharge among Chapter 13 bankruptcy filers in the district of Utah from 1997. The second objective was to use that same set of characteristics to predict the likelihood of dismissal at three critical stages of the bankruptcy process. Those stages were identified, first, as the period before the 341 hearing or meeting of creditors (n = 115 or 12.7%), second, before confirmation of the debtor's repayment plan (n = 267 or 29.4%), third, the period after confirmation of the plan and before discharge (n = 286 or 31 .5%). Once the best group of characteristics was discovered, the effects of demographic characteristics were compared against those of economic debtor characteristics as predictors of the outcome of the Chapter 13 cases. The results of the study show that demographic characteristics were, in general, better predictors than economic factors of the disposition of the Chapter 13 cases within the sample. Discharged and dismissed debtors were found to have statistically significantly different levels of certain types of debts based on pairwise t-test results. Although limited to one district, this study was the first to examine the likelihood of dismissal at three stages of bankruptcy prior to discharge. The study concluded that single debtors, debtors with children, debtors with previous bankruptcies, and those with higher levels of mortgage arrears were the most likely to be dismissed before completion of their repayment plan. Plan completion was generally achieved by those with higher job tenure and debtors with a mortgage. The results of the study support arguments against changes in current bankruptcy law and warrant further investigation of low Chapter 13 repayment plan completion rates in the district of Utah.

description: We extend the theory of non-thermal fixed points to the case of anomalously slow universal scaling dynamics according to the sine-Gordon model. This entails the derivation of a kinetic equation for the momentum occupancy of the scalar field from a non-perturbative two-particle irreducible effective action, which re-sums a series of closed loop chains akin to a large-$N$ expansion at next-to-leading order. The resulting kinetic equation is analyzed for possible scaling solutions in space and time that are characterized by a set of universal scaling exponents and encode self-similar transport to low momenta. Assuming the momentum occupancy distribution to exhibit a scaling form we can determine the exponents by identifying the dominating contributions to the scattering integral and power counting. If the field exhibits strong variations across many wells of the cosine potential, the scattering integral is dominated by the scattering of many quasiparticles such that the momentum of each single participating mode is only weakly constrained. Remarkably, in this case, in contrast to wave turbulent cascades, which correspond to local transport in momentum space, our results suggest that kinetic scattering here is dominated by rather non-local processes corresponding to a spatial containment in position space. The corresponding universal correlation functions in momentum and position space corroborate this conclusion. Numerical simulations performed in accompanying work yield scaling properties close to the ones predicted here.

title: Borrower- and Mortgage-Related Factors Associated with Foreclosure
Creators: name: Gallagher, Amber C.
Publisher: name: Utah State University
Year: 2004

description: The purpose of this study was to develop a conceptual model that could be used to aid in identifying which household factors contribute to an increased likelihood of foreclosure. More specifically, what borrower-related and mortgage-related factors are correlated with home foreclosure? This was achieved by studying a sample from an inventory of active and foreclosed Federal Housing Administration (FHA) homes in the state of Utah. The sample consisted of 179 cases. Characteristics of interest were extracted from data and divided into two categories: borrower-related factors and mortgage-related factors.
Bivariate, and multivariate analyses were conducted with the borrower- and mortgage-related factors. Among the major findings was the significance of race, front-end ratio, and interest rate in the likelihood of foreclosure. Similarly non- White borrowers were found as a concern group. Lastly, the presence of a first-time homebuyer and a high front-end ratio need to be viewed as potential factors leading to foreclosure.

This implies a model-independent prediction of the ratio R(W2,Q2)=sigma_L/sigma_T=0.375, or, equivalently, F_L/F_2=0.27, for x=Q2/W2<<1 and Q2 sufficiently large, while R(W2,Q2)=0.50, if this effect is ignored. Experimental data from HERA confirm the transverse-size reduction.

description: Dense non-Brownian suspensions exhibit a spectacular and abrupt drop in viscosity under change of shear direction, as revealed by shear inversions (reversals) or orthogonal superposition. Here, we introduce an experimental setup to systematically explore their response to shear rotations, where one suddenly rotates the principal axes of shear by an angle $θ$, and measure the shear stresses with a bi-axial force sensor. Our measurements confirm the genericness of the transient decrease of the resistance to shear under unsteady conditions. Moreover, the orthogonal shear stress, which vanishes in steady state, takes non-negligible values with a rich $θ$-dependence, changing qualitatively with solid volume fraction $ϕ$, and resulting in a force that tends to reduce or enhance the direction of flow for small or large $ϕ$. These experimental findings are confirmed and rationalized by particle-based numerical simulations and a recently proposed constitutive model. We show that the rotation angle dependence of the orthogonal stress results from a $ϕ$-dependent interplay between hydrodynamic and contact stresses.

description: It is well known that helical magnetohydrodynamic (MHD) turbulence exhibits an inverse transfer of magnetic energy from small to large scales, which is related to the approximate conservation of magnetic helicity. Recently, several numerical investigations noticed the existence of an inverse energy transfer also in nonhelical MHD flows. We run a set of fully resolved direct numerical simulations and perform a wide parameter study of the inverse energy transfer and the decaying laws of helical and nonhelical MHD. Our numerical results show only a small inverse transfer of energy that grows as with increasing Prandtl number (Pm). This latter feature may have interesting consequences for cosmic magnetic field evolution. Additionally, we find that the decaying laws $E \sim t^{-p}$ are independent of the scale separation and depend solely on Pm and Re. In the helical case we measure a dependence of the form $p_b \approx 0.6 + 14/Re$. We also make a comparison between our results and previous literature and discuss the possible reason for the observed disagreements

description: Autonomous cars are indispensable when humans go further down the hands-free route. Although existing literature highlights that the acceptance of the autonomous car will increase if it drives in a human-like manner, sparse research offers the naturalistic experience from a passenger's seat perspective to examine the humanness of current autonomous cars. The present study tested whether the AI driver could create a human-like ride experience for passengers based on 69 participants' feedback in a real-road scenario. We designed a ride experience-based version of the non-verbal Turing test for automated driving. Participants rode in autonomous cars (driven by either human or AI drivers) as a passenger and judged whether the driver was human or AI. The AI driver failed to pass our test because passengers detected the AI driver above chance. In contrast, when the human driver drove the car, the passengers' judgement was around chance. We further investigated how human passengers ascribe humanness in our test. Based on Lewin's field theory, we advanced a computational model combining signal detection theory with pre-trained language models to predict passengers' humanness rating behaviour. We employed affective transition between pre-study baseline emotions and corresponding post-stage emotions as the signal strength of our model. Results showed that the passengers' ascription of humanness would increase with the greater affective transition. Our study suggested an important role of affective transition in passengers' ascription of humanness, which might become a future direction for autonomous driving.

description: Atomistic machine learning focuses on the creation of models which obey fundamental symmetries of atomistic configurations, such as permutation, translation, and rotation invariances. In many of these schemes, translation and rotation invariance are achieved by building on scalar invariants, e.g., distances between atom pairs. There is growing interest in molecular representations that work internally with higher rank rotational tensors, e.g., vector displacements between atoms, and tensor products thereof. Here we present a framework for extending the Hierarchically Interacting Particle Neural Network (HIP-NN) with Tensor Sensitivity information (HIP-NN-TS) from each local atomic environment. Crucially, the method employs a weight tying strategy that allows direct incorporation of many-body information while adding very few model parameters. We show that HIP-NN-TS is more accurate than HIP-NN, with negligible increase in parameter count, for several datasets and network sizes. As the dataset becomes more complex, tensor sensitivities provide greater improvements to model accuracy. In particular, HIP-NN-TS achieves a record mean absolute error of 0.927 kcal/mol for conformational energy variation on the challenging COMP6 benchmark, which includes a broad set of organic molecules. We also compare the computational performance of HIP-NN-TS to HIP-NN and other models in the literature.

description: We calculate the quantum discord between two free modes of a scalar field which start in a maximally entangled state and then undergo a relative, constant acceleration. In a regime where there is no distillable entanglement due to the Unruh effect, we show that there is a finite amount of quantum discord, which is a measure of purely quantum correlations in a state, over and above quantum entanglement. Even in the limit of infinite acceleration of the observer detecting one of the modes, we provide evidence for a non-zero amount of purely quantum correlations, which might be exploited to gain non-trivial quantum advantages.

description: We analyze the quantum chaotic behavior of the Yukawa-SYK model as a function of filling and temperature, which describes random Yukawa interactions between $N$ complex fermions and $M$ bosons in zero spatial dimensions, for both the non-Fermi liquid and insulating states at finite temperature and chemical potential. We solve the ladder equations for the out-of-time-order correlator (OTOC) for both the bosons and fermions. Despite the appearance of the chemical potential in the Hamiltonian, which explicitly introduces an additional energy scale, the OTOCs for the fermions and bosons in the non-Fermi liquid state turn out to be unaffected, and the Lyapunov exponents that diagnose chaos remain maximal. As the chemical potential increases, the system is known to experience a first-order transition from a critical phase to a gapped insulating phase. We postulate that the boundary of the region in parameter space where each phase is (meta)stable coincides with the curve on which the Lyapunov exponent is maximal. By calculating the exponent in the insulating phase and comparing to numerical results on the boundaries of stability, we show that this is plausible.

description: ABSTRACT Objectives: To: 1) complete an integrative literature review of transition studies that focus on individuals with intersex traits; 2) conduct an environmental scan of the current resources (practice guidelines, policies, and procedures) used by healthcare providers working with Canadians with intersex traits; 3) investigate the experiences of Canadians with intersex traits in their healthcare transitions across the lifespan; and 4) assess the understanding of healthcare providers about these transitions. Design: A qualitative prospective community participation study was conducted. It used mixed methods including an environmental scan and semi-structured engagement sessions. Setting: The environmental scan examined resources available throughout Canada. The engagement sessions took place in British Columbia and Ontario, Canada. Participants: Sixteen participants were recruited. These included 13 individuals with intersex traits (a heterogenous group of congenital conditions affecting the development of sex characteristics), and three caregivers. Methods: Mixed methods included an integrated literature review, environmental scan and qualitative approaches developed in collaboration with community partners. Results: The literature review identified gaps in transition care for individuals with intersex traits. The environmental scan uncovered no specific resources used by health care providers working with patients with intersex traits, though several general guidelines were used. Engaging providers in the study was problematic. Thematic analysis generated three main themes that emerged from the engagement sessions: 1) transition is a lifespan activity; 2) building personal agency is valuable; and 3) wellbeing promotion is an application of health literacy. Conclusions: Transition resources for individuals living in Canada with intersex are scarce. Transitions happen across the lifespan with ownership of thought and actions seen as acts of personal agency. Health literacy skills and knowledge change with increased age, yet the primary source of knowledge often remained important in the individual’s auto-biographical self.
title: Marital Commitment and Religiosity in a Sample of Adults in Utah
Creators: name: Harris, Sharon S.
Publisher: name: Utah State University

description: This study examined the relationship of three types of martial commitment and religiosity factors in a random sample of I ,316 Utah adults. Participants were surveyed to assess attitudes of marriage, divorce, and marriage education. A lack of commitment was cited by 83% of divorced adults as a major factor for their divorce. The level of commitment to spouse, commitment to marriage, and constraint commitment was determined by extrapolating items from the 2003 Utah Marriage Movement Statewide Baseline Survey. Religiosity included measures of the frequency of church attendance, church affiliation, and religious values. Regression analyses that included socio-demographics showed the strongest and most consistent predictor of commitment to spouse and commitment to marriage was religious values. This study confirms the distinct difference but strong interplay between the three types of marital commitment. There was a negative relationship between both commitment to spouse and commitment to marriage and constraint commitment. Premarital cohabitation was positively related to constraint commitment but negatively related to commitment to spouse and commitment to marriage. Frequency of church attendance, conservative church affiliation (particularly The Church of Jesus Christ of Latter-day Saints religion), and religious values were all significant factors related statistically to marital commitment. Study findings suggest that educators and marriage therapists engaged in helping couples can productively focus on marital commitment, the influence of religious activity, and belief systems in strengthening marriage relationships.

description: We introduce a class of k-potential submanifolds in pseudo-Euclidean spaces and prove that for an arbitrary positive integer k and an arbitrary nonnegative integer p, each N-dimensional Frobenius manifold can always be locally realized as an N-dimensional k-potential submanifold in ((k + 1) N + p)-dimensional pseudo-Euclidean spaces of certain signatures. For k = 1 this construction was proposed by the present author in a previous paper (2006). The realization of concrete Frobenius manifolds is reduced to solving a consistent linear system of second-order partial differential equations.

description: We study the thermodynamic properties -- pressure, entropy and trace anomaly -- of a gas of glueballs that includes the glueball states obtained by various lattice simulations. We show that this model, called Glueball Resonance Gas (GRG) approach, describes well the thermal properties of the Yang-Mills sector of QCD below the critical temperature $T_c$, provided that $T_c$ is properly matched to the corresponding determination of the glueball masses, obtaining $T_c \sim 320 \pm 20$ MeV. The inclusion into the GRG of heavier glueballs not yet seen on the lattice, assuming that glueballs follow Regge trajectories as quark-antiquark states do, leads only to a small correction. We consider the contribution to the pressure of the interactions between scalar-scalar and tensor-tensor glueballs, which turn out to be also negligible.

description: We apply the recently established connection between nonlinear fluid dynamics and AdS gravity to the case of the dyonic black brane in AdS_4. This yields the equations of fluid dynamics for a 2+1 dimensional charged fluid in a background magnetic field. We construct the gravity solution to second order in the derivative expansion. From this we find the fluid dynamical stress tensor and charge current to second and third order in derivatives respectively, along with values for the associated transport coefficients.

description: Emerging viruses have caused concerns about pollinator population declines, as multi-host RNA viruses may pose a health threat to pollinators and associated arthropods. In order to understand the ecology and impact these viruses have, we studied their host range and determined to what extent host and spatial variation affect strain diversity. Firstly, we used RT-PCR to screen pollinators and associates, including honey bees (Apis mellifera) and invasive Argentine ants (Linepithema humile), for virus presence and replication. We tested for the black queen cell virus (BQCV), deformed wing virus (DWV), and Kashmir bee virus (KBV) that were initially detected in bees, and the two recently discovered Linepithema humile bunya-like virus 1 (LhuBLV1) and Moku virus (MKV). DWV, KBV, and MKV were detected and replicated in a wide range of hosts and commonly co-infected hymenopterans. Secondly, we placed KBV and DWV in a global phylogeny with sequences from various countries and hosts to determine the association of geographic origin and host with shared ancestry. Both phylogenies showed strong geographic rather than host-specific clustering, suggesting frequent inter-species virus transmission. Transmission routes between hosts are largely unknown. Nonetheless, avoiding the introduction of non-native species and diseased pollinators appears important to limit spill overs and disease emergence.

description: We study the puzzling vector meson X(2175) in a multichannel generalisation of the Resonance-Spectrum-Expansion model. Besides the usual P-wave pseudoscalar-pseudoscalar, pseudoscalar-vector, and vector-vector channels that couple to mesons with vector quantum numbers, we also include the important S-wave vector-scalar, pseudoscalar-axialvector and vector-axialvector channels, including the observed $ϕ$(1020)$f_0$(980) decay mode. The strong coupling to nearby S-wave channels originates dynamically generated poles, two of which come out close to the energy region of the X(2175), viz. at (2.037-i0.170) GeV and (2.382-i0.20) GeV. Further improvements are proposed.

description: We study the role of dark and bright autoionizing states (AIS) in photoionization and high harmonic generation (HHG) using a 1D helium model. This model allows numerical integration of the time-dependent Schrödinger equation beyond the singe-electron approximation completely taking into account electronic correlation. We find the level structure of the system and the spatial distribution of the electronic density for several states including AIS. Studying the HHG efficiency as a function of the detuning from the resonances with AIS we find the HHG enhancement lines. The shapes of these lines are different from the corresponding Fano lines in the photoelectronic spectra, in agreement with the experimental studies in helium. Moreover, we simulate HHG under the conditions when the fundamental frequency is close to the even-order multiphoton resonance with the dark AIS. We find the enhanced generation of the neighbouring odd harmonics. The details of the enhancement lines for these harmonics can be understood taking into account the temporal delay between the emission of the non-resonant and resonant XUV; this delay is defined by the AIS lifetime. Finally, our simulations show that the HHG enhancement due to the dark and the bright AIS is comparable in the studied system.

description: We study a conformally coupled scalar-tensor theory with a quartic potential possessing local conformal symmetry up to a boundary term. We show that requiring the restoration of the full local conformal symmetry fixes the counterterms that render the on-shell action finite. The building block of the resulting action is a conformally covariant tensor which is constructed out of the metric and the scalar field and it has the same conformal weight as the Weyl tensor. This allows us to obtain the counterterms for the scalar-tensor sector in a closed form. The finiteness of the conformally complete version of the action is suggestive on the validity of the Conformal Renormalization prescription. We extend this theory by adding the Conformal Gravity action and also the Einstein-AdS action written in McDowell-Mansouri form. Even though the latter breaks the conformal symmetry, we find that the action is still renormalized provided a suitable falloff of the scalar field when considering asymptotically locally anti-de Sitter solutions. Black hole solutions in these theories are studied, for which the Hawking temperature and the partition function to first order in the saddle-point approximation are calculated, providing a concrete example of this renormalization scheme.
