description: To write a history of those whose sexualities fell outside the bounds of the legal, the acceptable, or even the recognizable poses enormous challenges, even more so when the terms such as ‘sexuality’ hardly existed in the period. Indeed, the terms homosexual and heterosexual were coined in 1868 to denote sexual deviancy, that is, sexual acts which had erotic aims deprived of any procreative function.1 How can we know about the sexual practices of the ‘ordinary individual’, who leaves no written record of everyday sexuality, whether of licit, procreative and marital intercourse, or of the illicit. To look at, for instance, court records of sodomy, one reproduces the language of deviance and disempowers the original subject yet again. To use medical records, one reinforces the psychiatric and medical discourses of ‘moral degeneracy’ or ‘moral illness’, and the queer subject becomes, yet again, a patient. Yet these problems can and are overcome with sensitive use of the court or medical material. What of the majority of individuals who never came to the attention of court or doctor, whose lives and loves were unrecorded, and often unlived fully, due to the fear of disclosure or the interiorisation of society’s disdain?
Tunneling Through a One-Dimensional Piece Wise Constant Potential Barrier

description: In this paper we look at transmission through one-dimensional potential barriers that are piece wise constant. The Transfer Matrix approach is adopted and a new formula is derived for multiplying long matrix sequences that not only leads to an elegant representation of the wave function, but also results in much faster computation than earlier methods. The proposed method covers a broad spectrum of potentials of which multi-barrier systems are special cases. The paradigm is exemplified with a finite lattice of non-uniform rectangular barriers - non-uniformity being crucial, as the uniform case has been solved exactly by Griffiths and Steinke. For the non-uniform multi-barrier problem, the intervening wells strongly influence the transmission probability. Surprisingly, we find that the wells act 'individually', i.e. their influence is only a function of their width and is independent of their exact 'location' in a multi-barrier system. This leads to a startling observation, which we have termed as the 'Alias Effect.' The exact solutions are supported with asymptotic formulas.

description: In this paper, we calculate corrections of scalar perturbations spectra resulting from excited-de Sitter modes as the nontrivial initial states. To obtain these modes, we consider the asymptotic expansion of the Hankel functions up to the higher order of 1/kτ . Actually the Planck and WMAP data impose some constrains on the Hankel function index. These observational constraints and back-reaction effects stimulate us to use excited-de Sitter modes. Finally, we nominate these nontrivial general solutions as the fundamental mode functions during inflation and we calculate the corrected form of scale-dependent power spectrum with trans-Planckian corrections, and in de Sitter space-time limit the results reduce to the scale-invariant power spectrum.

description: We theoretically study the propagation of large-wavevector waves (volume plasmon polaritons) in multilayer hyperbolic metamaterials with two levels of structuring. We show that when the parameters of a subwavelength metal-dielectric multilayer ("substructure") are modulated ("superstructured") on a larger, wavelength scale, the propagation of volume plasmon polaritons in the resulting multiscale hyperbolic metamaterials is subject to photonic band gap phenomena. A great degree of control over such plasmons can be exerted by varying the superstructure geometry. When this geometry is periodic, stop bands due to Bragg reflection form within the volume plasmonic band. When a cavity layer is introduced in an otherwise periodic superstructure, resonance peaks of the Fabry-Perot nature are present within the stop bands. More complicated superstructure geometries are also considered. For example, fractal Cantor-like multiscale metamaterials are found to exhibit characteristic self-similar spectral signatures in the volume plasmonic band. Multiscale hyperbolic metamaterials are shown to be a promising platform for large-wavevector bulk plasmonic waves, whether they are considered for use as a new kind of information carrier or for far-field subwavelength imaging.

Terminal-restriction fragment length polymorphism (T-RFLP) is a DNA-based technique used to examine microbial community structure. We used this technique to examine variability in microbial community structure in 3 pools and a riffle in a semipermanent stream that becomes a chain of pools during the summer. We examined microbial communities under 3 hydrological conditions: predrought (all sites inundated), drought (all sediments dried for >= 2 mo), and rewet (1 mo after inundation). We used nonmetric multidimensional scaling to ordinate microbial communities and analysis of similarity to test whether communities differed among sites and whether community structure within sites changed in response to drought and rewetting. Microbial communities within sites differed with respect to hydrological condition, with most within-site variability occurring within the riffle section of the stream. Sediment drying significantly changed the microbial community structure at all sites. One month after rewetting at all sites, the microbial communities had not returned to their predrought structures and were significantly different from the predrought and drought microbial communities. Within-site variability in microbial community structure was much lower after the drought than before the drought. T-RFLP proved to be a powerful method for resolving microbial community structure, and its application helped address our limited understanding of microbial community dynamics.

description: Large scale simulations of two-dimensional bidisperse granular fluids allow us to determine spatial correlations of slow particles via the four-point structure factor $S_4(q,t)$. Both cases, elastic ($\varepsilon=1$) as well as inelastic ($\varepsilon < 1$) collisions, are studied. As the fluid approaches structural arrest, i.e. for packing fractions in the range $0.6 \le ϕ\le 0.805$, scaling is shown to hold: $S_4(q,t)/χ_4(t)=s(qξ(t))$. Both the dynamic susceptibility, $χ_4(τ_α)$, as well as the dynamic correlation length, $ξ(τ_α)$, evaluated at the $α$ relaxation time, $τ_α$, can be fitted to a power law divergence at a critical packing fraction. The measured $ξ(τ_α)$ widely exceeds the largest one previously observed for hard sphere 3d fluids. The number of particles in a slow cluster and the correlation length are related by a robust power law, $χ_4(τ_α) \approxξ^{d-p}(τ_α)$, with an exponent $d-p\approx 1.6$. This scaling is remarkably independent of $\varepsilon$, even though the strength of the dynamical heterogeneity increases dramatically as $\varepsilon$ grows.

description: A quantum emitter efficiently coupled to a nanophotonic waveguide constitutes a promising system for the realization of single-photon transistors, quantum-logic gates based on giant single-photon nonlinearities, and high bit-rate deterministic single-photon sources. The key figure of merit for such devices is the $β$-factor, which is the probability for an emitted single photon to be channeled into a desired waveguide mode. We report on the experimental achievement of $β= 98.43 \pm 0.04\%$ for a quantum dot coupled to a photonic-crystal waveguide, corresponding to a single-emitter cooperativity of $η= 62.7 \pm 1.5$. This constitutes a nearly ideal photon-matter interface where the quantum dot acts effectively as a 1D "artificial" atom, since it interacts almost exclusively with just a single propagating optical mode. The $β$-factor is found to be remarkably robust to variations in position and emission wavelength of the quantum dots. Our work demonstrates the extraordinary potential of photonic-crystal waveguides for highly efficient single-photon generation and on-chip photon-photon interaction.

description: The backbone of global geodetic reference frames are results obtained from space geodetic techniques such as Very Long Baseline Interferometry (VLBI), Satellite Laser Ranging (SLR), Global Navigation Satellite Systems (GNSS), and Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS). Further information is introduced to tie these techniques during the combination process. One of the most crucial information is local tie vectors at multi-technique stations yielding the length and the orientation of hosted space geodetic instruments. Local ties are defined between the geometrical reference points of these instruments. In this contribution, a novel approach using close-range photogrammetry is presented in the framework of reference point determination. The reference point of the Satellite Observing System Wettzell, a modern two-color SLR telescope, is derived several times using different configurations and approaches. The variations of the derived reference point are less than 0.5 mm and are promising to fulfill the requirements of the Global Geodetic Observing System.

description: The apparent excess of gamma rays in an extended region in the direction of the galactic center has a spatial distribution and amplitude that are suggestive of dark matter annihilations. If this excess is indeed due to dark matter annihilations, it would indicate the presence of both dark matter and an additional particle beyond the Standard Model that mediates the interactions between the dark matter and Standard Model states. We introduce reference models describing dark matter annihilation to pairs of these new mediators, which decouples the SM-mediator coupling from the thermal annihilation cross section and easily explains the lack of direct detection signals. We determine the parameter regions that give good descriptions of the gamma ray excess for several motivated choices of mediator couplings to the SM. We find fermion dark matter with mass 7-26 GeV and a dark vector mediator, or scalar dark matter in the 10-50 GeV range (Higgs portal mediator) or 10-65 GeV range (gluophilic mediator) can provide a comparable or improved fit, compared to the case of direct annihilation. We demonstrate that these models can easily satisfy all constraints from collider experiments, direct detection, and cosmology.

title: Establishment of a Transgenic Human Angiotensin Converting Enzyme-2 Hamster Infection Model for the Evaluation of Therapeutics Against Severe Acute Respiratory Syndrome Coronavirus 2
Creators: name: Gibson, Scott A.
Publisher: name: Utah State University

description: The virus SARS-CoV-2 emerged in late 2019 and has gone on to spread throughout the global population. The virus is still the cause of a healthcare crisis two years after being identified. Viral infection in humans leads to the development of the disease COVID-19. A complex disease that can result in a wide variety of outcomes for infected individuals. In the majority of individuals, COVID-19 will manifest as either an asymptomatic disease state or a mild to moderate disease state that is resolved in approximately one week. In some infected patients COVID-19 will manifest with the rapid onset of severe symptoms such as breathing difficulties. In severe cases, a marked inflammatory response results in the development of life-threatening acute respiratory distress syndrome (ARDS). In a small number of autopsies preformed on patients who died due to COVID-19, signs of encephalitis and/or stroke are observable. Neurological symptoms during infection or the development of psychiatric disorders following infection have been reported in multiple clinical reports.
To effectively combat SARS-CoV-2 spread and infection, it is crucial for us to understand the full array of disease manifestations and identify therapeutics available to combat severe infections. We have developed an animal infection model of SARS-CoV-2 in transgenic hACE2 hamsters. Virus challenge in hACE2 hamsters leads to mild to moderate clinical signs beginning ~ 2 dpi, after which symptoms quickly progress to severe as evidenced by observable difficulty breathing in hamsters. Infected hamsters succumb to SARS-CoV-2 infection at approximately 6 – 7 dpi. Infectious virus was found in lung, brain, cardiac, and renal tissue of infected hamsters. Virus titers peaked in tissues just prior to the onset of severe symptoms (~4dpi). Microscopic evaluation of hamster tissues revealed inflammation and necrosis in lung and brain tissue. Mortality in hACE2 hamsters is presumed to be the result of a combination of respiratory and neurological damage, since wild-type golden Syrian hamsters infected with SARS-CoV-2 show similar to greater pathology the lung but lack the encephalitis seen in hACE2 hamsters. Therefore, it is our conclusion that SARS-CoV-2 associated death is due in part to the neurologic pathology observed. The hACE2 hamsters model for SARS-CoV-2 infection is a model of severe SARS-CoV-2 symptomology with neurologic involvement.

description: Living at high-altitude is one of the most difficult challenges that humans had to cope with during their evolution. Whereas several genomic studies have revealed some of the genetic bases of adaptations in Tibetan, Andean and Ethiopian populations, relatively little evidence of convergent evolution to altitude in different continents has accumulated. This lack of evidence can be due to truly different evolutionary responses, but it can be also due to the low power of former studies that have mainly focused on populations from a single geographical region or performed separate analyses on multiple pairs of populations to avoid problems linked to shared histories between some populations. We introduce here a hierarchical Bayesian method to detect local adaptation that can deal with complex demographic histories. Our method can identify selection occurring at different scales, as well as convergent adaptation in different regions. We apply our approach to the analysis of a large SNP dataset from low- and high-altitude human populations from America and Asia. The simultaneous analysis of these two geographic areas allows us to identify several candidate genome regions for altitudinal selection, and we show that convergent evolution among continents has been quite common. In addition to identifying several genes and biological processes involved in high altitude adaptation, we identify two specific biological pathways that could have evolved in both continents to counter toxic effects induced by hypoxia.

description: We introduce a microwave bolometer aimed at high-quantum-efficiency detection of wave packet energy within the framework of circuit quantum electrodynamics, the ultimate goal being single microwave photon detection. We measure the differential thermal conductance between the detector and its heat bath, obtaining values as low as 5 fW/K at 50 mK. This is one tenth of the thermal conductance quantum and corresponds to a theoretical lower bound on noise-equivalent-power of order $10^{-20}$ $W/\sqrt{\mbox{Hz}}$ at 50 mK. By measuring the differential thermal conductance of the same bolometer design in qualitatively different environments and materials, we determine that electron--photon coupling dominates the thermalization of our nanobolometer.

description: We present a detailed study for the finite-frequency current noise of a Kondo quantum dot in presence of a magnetic field by using a recently developed real time functional renormalization group approach [Phys. Rev. B $\mathbf{83}$, 201303(R) (2011)]. The scaling equations are modified in an external magnetic field; the couplings and non-local current vertices become strongly anisotropic, and develop new singularities. Consequently, in addition to the natural emission threshold frequency, $\hbarω= |eV|$, a corresponding singular behavior is found to emerge in the noise spectrum at frequencies $\hbar ω\approx |eV\pm B|$. The predicted singularities are measurable with present-day experimental techniques.

description: We study the distribution of work induced by the two-point measurement protocol for a driven open quantum system. We first derive a general form for the generating function of work for the total system, bearing in mind that the Hamiltonian does not necessarily commute with its time derivative. Using this result we then study the first few moments of work by using the master equation of the reduced system, invoking approximations similar to the ones made in the microscopic derivation of the reduced density matrix. Our results show that, already in the third moment of work, correction terms appear that involve commutators between the Hamiltonian and its time derivative. To demonstrate the importance of these terms, we consider a sinusoidally, weakly driven and weakly coupled open two-level quantum system, and indeed find that already in the third moment of work the correction terms are significant. We also compare our results to those obtained with the quantum jump method and find a good agreement.

We work out an explicit example, namely the non-linear sigma model in the leading order in $1/N$ expansion.
Precise Calculation of the Dilepton Invariant-Mass Spectrum and the Decay Rate in $B^\pm \to π^\pm μ^+ μ^-$ in the SM

description: We present a precise calculation of the dilepton invariant-mass spectrum and the decay rate for $B^\pm \to π^\pm \ell^+ \ell^-$ ($\ell^\pm = e^\pm, μ^\pm $) in the Standard Model (SM) based on the effective Hamiltonian approach for the $b \to d \ell^+ \ell^-$ transitions. With the Wilson coefficients already known in the next-to-next-to-leading logarithmic (NNLL) accuracy, the remaining theoretical uncertainty in the short-distance contribution resides in the form factors $f_+ (q^2)$, $f_0 (q^2)$ and $f_T (q^2)$. Of these, $f_+ (q^2)$ is well measured in the charged-current semileptonic decays $B \to π\ell ν_\ell$ and we use the $B$-factory data to parametrize it. The corresponding form factors for the $B \to K$ transitions have been calculated in the Lattice-QCD approach for large-$q^2$ and extrapolated to the entire $q^2$-region using the so-called $z$-expansion. Using an $SU(3)_F$-breaking Ansatz, we calculate the $B \to π$ tensor form factor, which is consistent with the recently reported lattice $B \to π$ analysis obtained at large~$q^2$. The prediction for the total branching fraction ${\cal B} (B^\pm \to π^\pm μ^+ μ^-) = (1.88 ^{+0.32}_{-0.21}) \times 10^{-8}$ is in good agreement with the experimental value obtained by the LHCb Collaboration. In the low $q^2$-region, heavy-quark symmetry (HQS) relates the three form factors with each other. Accounting for the leading-order symmetry-breaking effects, and using data from the charged-current process $B \to π\ell ν_\ell$ to determine $f_+ (q^2)$, we calculate the dilepton invariant-mass distribution in the low $q^2$-region in the $B^\pm \to π^\pm \ell^+ \ell^-$ decay. This provides a model-independent and precise calculation of the partial branching ratio for this decay.

title: Estimating Seasonal Crop Water Consumption in Irrigated Lands Using Soil Moisture and Reference Evapotranspiration
Creators: name: Hargreaves, Oliver Henry
Publisher: name: Utah State University
Year: 2023

description: The increase in population and the megadrought that the American west has been experiencing for the past two decades and for the foreseeable future are the cause of great stress on the region’s water resources. In an effort to mitigate the worst effects of water shortages many public and private agencies have been pursuing ways to reduce water use while maintaining the current status quo of living standards, industrial productivity, and agricultural yield. This project aims to study water use in irrigated lands dedicated to agriculture with the objective of quantifying crop water use, often referred to as evapotranspiration (ET), as this is among the most important metrics when it comes to increasing water use efficiency, i.e., increasing the amount of agricultural output per amount of water input.
This study aims to develop a methodology that allows land managers to estimate evapotranspiration using familiar tools and data i.e., soil moisture sensors. The first study site in Vernal, Utah, was used to develop the proposed methodology because alongside the soil moisture data, accurate evapotranspiration measurements were available which allowed for the calibration and verification of the model. The second study site in Modena, Utah, in which accurate evapotranspiration measurements were also available, was used as a testing ground for the estimates provided by the proposed methodology allowing to assess whether local calibration was required or not. The third study site in West Weber, Utah, where two irrigation methods (drip and flood irrigation) were employed, was used as a practical example of how this methodology could be implemented in a real farm scenario and what insight could be gained from it.
The proposed Soil Moisture based EvapoTranspiration (SMET) estimation model reliably provided accurate results (within ±7%) in the first two study sites where they could be compared with results from more sophisticated methods. In the third study site the SMET model offered previously hard to obtain insight on how the water use is influenced by the two irrigation techniques employed and on how water use can differ even within the same field. The encouraging results from this study prove that this user-friendly and low-cost crop water use estimation method can provide managers, producers, and policy makers with an accurate number, allowing for better-informed decisions regarding water conservation and maximizing the beneficial use of this limited resource.

description: We study the scattering of longitudinally polarized W bosons in extensions of the Standard Model where anomalous Higgs couplings to gauge sector and higher order O(p^4) operators are considered. These new couplings with respect to the Standard Model should be thought as the low energy remnants of some new dynamics involving the electroweak symmetry breaking sector. By imposing unitarity and causality constraints on the WW scattering amplitudes we find relevant restrictions on the possible values of the new couplings and the presence of new resonances above 300 GeV. We investigate the properties of these new resonances and their experimental detectability. Custodial symmetry is assumed to be exact throughout and the calculation avoids using the Equivalence Theorem as much as possible.

description: The nature of the cosmological dark matter remains elusive. Recent studies have advocated the possibility that dark matter could be composed of ultra-light, self-interacting bosons, forming a Bose-Einstein condensate in the very early Universe. We consider models which are charged under a global U(1)-symmetry such that the dark matter number is conserved. It can then be described as a classical complex scalar field which evolves in an expanding Universe. We present a brief review on the bounds on the model parameters from cosmological and galactic observations, along with the properties of galactic halos which result from such a dark matter candidate.

description: Abstract
The current study has investigated the relationship between Job Satisfaction and their effect on organizational citizenship behavior among college faculties. The data were collected from 189 respondents from different colleges in Tamil Nadu. Job Satisfaction is positively associated with all the dimensions of OCB by the faculties of the colleges. Therefore, it was suggested that colleges should facilitate the process leading to Job satisfaction, so that staffs are better engaged in additional role behavior resulting in improved single and organizational effectiveness.
Measures of disturbance and incompatibility for quantum measurements

description: We propose a class of incompatibility measures for quantum observables based on quantifying the effect of a measurement of one observable on the statistics of the outcomes of another. Specifically, for a pair of observables $A$ and $B$ with purely discrete spectra, we compare the following two probability distributions: one resulting from a measurement of $A$ followed by a measurement of $B$ on a given state, and the other obtained from a measurement of $B$ alone on the same state. We show that maximizing the distance between these two distributions over all states yields a valid measure of the incompatibility of observables $A$ and $B$, which is zero if and only if they commute and is strictly greater than zero (and less than or equal to one) otherwise. For finite dimensional systems, we obtain a tight upper bound on the incompatibility of any pair of observables and show that the bound is attained when the observables are totally non-degenerate and associated with mutually unbiased bases. In the process, we also establish an important connection between the incompatibility of a pair of observables and the maximal disturbances due to their measurements. Finally, we indicate how these measures of incompatibility and disturbance can be extended to the more general class of non-projective measurements. In particular, we obtain a non-trivial upper bound on the incompatibility of one Lüders instrument with another.

description: We have synthesized several morphologies and crystal structures of MgWO4 using a one-pot hydrothermal method, producing not only monoclinic stars and large nanoparticles but also triclinic wool balls and sub-10 nm nanoparticles. Herein we describe the importance of reaction parameters in demonstrating morphology control of as-prepared MgWO4. Moreover, we correlate structure and composition with the resulting photoluminescence and radioluminescence properties. Specifically, triclinic-phase samples yielded a photoluminescence emission of 421 nm, whereas monoclinic-phase materials gave rise to an emission maximum of 515 nm. The corresponding radioluminescence data were characterized by a broad emission peak, located at 500 nm for all samples. Annealing the wool balls and sub-10 nm particles to transform the crystal structure from a triclinic to a monoclinic phase yielded an RL emission signal that was two orders of magnitude greater than that of their unannealed counterparts. Finally, to confirm the practical utility of these materials for biomedical applications, a series of sub-10 nm particles, including as-prepared and annealed samples, were functionalized with biocompatible PEG molecules, and subsequently were found to be readily uptaken by various cell lines as well as primary cultured hippocampal neurons with low levels of toxicity, thereby highlighting for the first time the potential of this particular class of metal oxides as viable and readily generated platforms for a range of biomedical applications.

description: The recent detection in archival HST images of an object at the the location of supernova (SN) iPTF13bvn may represent the first direct evidence of the progenitor of a Type Ib SN. The object's photometry was found to be compatible with a Wolf-Rayet pre-SN star mass of ~11 Msun. However, based on hydrodynamical models we show that the progenitor had a pre-SN mass of ~3.5 Msun and that it could not be larger than ~8 Msun. We propose an interacting binary system as the SN progenitor and perform evolutionary calculations that are able to self-consistently explain the light-curve shape, the absence of hydrogen, and the pre-SN photometry. We further discuss the range of allowed binary systems and predict that the remaining companion is a luminous O-type star of significantly lower flux in the optical than the pre-SN object. A future detection of such star may be possible and would provide the first robust identification of a progenitor system for a Type Ib SN.

1. The response of a species to environmental disturbance is largely mediated by its life history traits that have evolved within a particular habitat template. Altered flow seasonality, as a direct consequence of river regulation, is a major environmental disturbance and has been implicated in the redistribution of a range of riverine organisms. An understanding of the reasons for species-specific responses, however, has proved elusive. 2. Here, we investigated the reproduction of three riverine shrimp species (Paratya australiensis, Caridina mccullochi and Macrobrachium australiense) that show contrasting patterns in distribution and abundance in regulated Australian rivers. 3. In all three species, breeding females were largest, and fecundity was greatest early in the breeding season (November–December). Fecundity and egg size subsequently declined, with lower investment (overall and per offspring) perhaps indicating that conditions for larvae were more favourable later in the breeding season (a time normally characterised by low flow, warm water and high productivity). 4. Interspecific differences in absolute values of reproductive traits were, however, striking. Paratya australiensis has typically 'opportunistic' traits (small body size, small eggs and high fecundity), whereas M. australiense has more 'equilibrium' traits (larger body size, larger eggs and moderate fecundity). Caridina mccullochi is intermediate, having neither high fecundity nor large size, and has limited swimming ability when young. This species is now absent from at least one heavily regulated river in south-eastern Australia, and we hypothesise that its life history may explain this absence. 5. Studies involving aspects of life history, such as reproductive traits, are likely to improve our understanding of a range of organisms and assist in the management of disturbed or altered environments.
Quantum coherence and uncertainty in the anisotropic XY chain

description: We explore the local quantum coherence and the local quantum uncertainty, based on Wigner-Yanase skew information, in the ground state of the anisotropic spin-1/2 XY chain in transverse magnetic field. We show that the skew information, as a figure of merit, supplies the necessary information to reveal the occurrence of the second order phase transition and the completely factorized ground state in the XY model. Additionally, in the same context, we also discuss the usefulness of a simple experimentally friendly lower bound of local quantum coherence. Furthermore, we demonstrate how the connection between the appearance of non-analyticities in the local quantum uncertainty of the ground state and the quantum phase transitions does not hold in general, by providing explicit examples of the situation. Lastly, we discuss the ability of the local quantum coherence to accurately estimate the critical point of the phase transition, and investigate the robustness of the factorization phenomenon at low temperatures.

description: We performed a nuclear magnetometry study on quantum Hall ferromagnet with a bilayer total filling factor of $ν_{\rm{tot}} = 2$. We found not only a rapid nuclear relaxation but also a sudden change in the nuclear spin polarization distribution after a one-second interaction with a canted antiferromagnetic phase. We discuss the possibility of observing cooperative phenomena coming from nuclear spin ensemble triggered by electrons with collective spin interactions.
