Modeling columnar thin films as platforms for surface-plasmonic-polaritonic optical sensing

description: Via exploitation of surface plasmon polaritons (SPPs), columnar thin films (CTFs) are attractive potential platforms for optical sensing as their relative permittivity dyadic and porosity can be tailored to order. Nanoscale model parameters of a CTF were determined from its measured relative permittivity dyadic, after inverting the Bruggeman homogenization formalism. These model parameters were then used to determine the relative permittivity dyadic of a fluid-infiltrated CTF. Two boundary-value problems were next solved: the first relating to SPP-wave propagation guided by the planar interface of a semi-infinitely thick metal and a semi-infinitely thick CTF, and the second to the plane-wave response of the planar interface of a finitely thick metallic layer and a CTF in a modified Kretschmann configuration. Numerical studies revealed that SPP waves propagate at a lower phase speed and with a shorter propagation length, if the fluid has a larger refractive index. Furthermore, the angle of incidence required to excite an SPP wave in a modified Kretschmann configuration increases as the refractive index of the fluid increases.
title: Development of Ecologically-Based Invasive Plant Management Curriculum for University Audiences
Creators: name: Kartchner, Halley
Publisher: name: Utah State University
Year: 2013

description: The Great Basin is considered one of the most endangered ecoregions in the United States. One threat facing Great Basin rangelands is the invasion of harmful, non-native plants. These invasive weeds outcompete native plants, degrade wildlife habitat, decrease valuable forage for livestock, and cost millions every year in weed control efforts. In order to restore degraded ecosystems of the Great Basin, it is essential that effective weed management programs are integrated in rangeland management strategies. Traditional management approaches have focused on killing invasive weeds with limited regard to the underlying processes that contributed to the invasion.
Ecologically-based invasive plant management, or EBIPM, is an alternative holistic management approach that aims to understand and manipulate the ecological processes influencing weed invasions, and works to prevent further invasions as well as to treat areas that are already dominated by invasive weeds. EBIPM combines rangeland health assessment, successional theory, ecological principles, tools and strategies, and adaptive management in a 5-step, decision-making framework for a proactive approach to treating and preventing the spread of invasive weeds. The EBIPM method is arranged in a five step framework.
Outreach and education is an important part of a weed management program like EBIPM, as it helps to create awareness and acceptance among managers, policy makers, and the public. EBIPM outreach and education efforts include: a field school that has been held the past 4 years, field tours to demonstrate new techniques and research, manager guidebooks to teach professionals about the EBIPM process, a high school curriculum, and a website.
In order to inform future land managers about EBIPM, a university curriculum has been created to fit into a wide variety of undergraduate courses. This curriculum is compromised of six modules. The first module provides an overview of the EBIPM decision-making framework. The subsequent five modules are aligned with the five steps in the framework. Each module contains a synoptic reading describing the linkages between ecological concepts and management practices, case studies, in-class and field activities, review questions, additional resources, and a Power Point presentation. Each of the modules was reviewed and assessed by a weed ecologist, outreach education specialist, and a media specialist. The curriculum is posted online for access by university students and educators.

description: In this note we consider the algebra $U_q(\hat{sl}_\infty)$ and we study the category O of its integrable representations. The main motivations are applications to quantum toroidal algebras, more precisely predictions of character formulae for representations of quantum toroidal algebras. In this context, we state a general positivity conjecture for representations of $U_q(\hat{sl}_\infty)$ viewed as representations of quantum toroidal algebras, that we prove for Kirillov-Reshetikhin modules.

title: The Relationship Between Confidence and Performance Throughout a Competitive Season
Creators: name: Skinner, Benjiman R.
Publisher: name: Utah State University
Year: 2013

description: The importance of understanding how confidence varies across time has been encouraged by sport confidence researchers (Vealey & Chase, 2008). The purpose of this study was to examine the relationship between confidence and performance throughout an entire competitive season. Two levels of confidence consistent to team sports were analyzed. Team and coach confidence were collected through the Collective Efficacy Questionnaire for Sport (CEQS) and Coaching Efficacy Scale (CES) respectively. Two teams, women’s soccer and volleyball (n=48) from a college in the western United States, completed their specific questionnaires five times throughout the season. The CEQS measured collective efficacy (team confidence) and the CES measured coaching efficacy (coach confidence) for each team. Simple linear regressions were used to determine the relationship team confidence and coaching confidence had on the success of each team. Pearson’s correlation coefficients were taken to determine if team and coach confidence were connected throughout the season. Volleyball was statistically significant for both team and coach confidence at p = 0.033 and p = 0.040 respectively, with a .68 correlation coefficient. Conversely, the soccer team was not statistically significant for both team and coach confidence at p = 0.53 and p = 0.93 for each. There was, however, a strong correlation coefficient at .89 for the two levels. The findings suggest that team and coach confidence may be related and associated with the success of the team. The results also hint, through the correlation coefficients, that team and coach confidence may be connected.

description: In this paper we present a model exhibiting a new type of continuous-time quantum walk (as a quantum mechanical transport process) on networks, which is described by a non-Hermitian Hamiltonian possessing a real spectrum. We call it pseudo-Hermitian continuous-time quantum walk. We introduce a method to obtain the probability distribution of walk on any vertex and then study a specific system. We observe that the probability distribution on certain vertices increases compared to that of the Hermitian case. This formalism makes the transport process faster and can be useful for search algorithms.

description: Multiphoton contributions pose a significant challenge for the realisation of heralded single-photon sources (HSPS) based on nonlinear processes. In this work, we improve the quality of single photons generated in this way by harnessing the photon-number resolving (PNR) capabilities of commercial superconducting nanowire single-photon detectors (SNSPDs). We report a $13 \pm 0.4 \%$ reduction in the intensity correlation function $g^{(2)}(0)$ even with a collection efficiency in the photon source of only $29.6\%$. Our work demonstrates the first application of the PNR capabilities of SNSPDs and shows improvement in the quality of an HSPS with widely available technology.

description: We propose and analyze a spin wave amplifier aimed to enhance the amplitude of the propagating spin wave via the magnetoelectric effect. The amplifier is a two-layer multiferroic structure, which comprises piezoelectric and ferromagnetic materials. By applying electric field to the piezoelectric layer, the stress is produced. In turn, the stress changes the direction of the easy axis in the ferromagnetic layer and the direction of the anisotropy field. The rotation frequency of the easy axis is the same as the frequency of the spin wave propagating through the ferromagnetic layer. As a result of this two-stage process, the amplitude of the spin wave can be amplified depending on the angle of the easy axis rotation. We present results of numerical simulations illustrating the operation of the proposed amplifier. According to numerical estimates, the amplitude of the spin wave signal can be increased by several orders of magnitude. The energy efficiency of the electric-to-magnetic power conversion is discussed. The proposed amplifier preserves the phase of the initial signal, which is important for application to logic circuits based on spin waves.

Nous presentons de facon minutieuse l'organisation des activites de production pour saisir le type de rationalite inscrit dans un tel systeme economique et pour montrer le role joue par la monnaie dans la mediation des relations sociales. Ceci nous permet d'articuler le niveau de production domestique aux relations de pouvoir entre les secteurs indigene et europeen par la place qu'occupe la consommation ostentatoire dans le proces de differenciation sociale au village. La seconde partie de la these porte sur la fagon dont les villageois ont tente de resoudre l'inegalite des formes de pouvoir entre secteurs indigene et europeen. Cette partie decrit la forme et le contenu de l'arene politique villageoise, presente la dimension politique des liens entre le village et la ville, et mesure le degre d'autonomie politique que la commu-naute a su preserver.

description: We analyze the efficiency of the quantum Otto cycle applied to a superconducting cavity. We consider its description in terms of a full quantum scalar field in a one-dimensional cavity with a time dependent boundary condition that can be externally controlled to perform and extract work unitarily from the system. We study the performance of this machine when acting as a heat engine as well as a refrigerator. It is shown that, in a non-adiabatic regime, the efficiency of the quantum cycle is affected by the dynamical Casimir effect, that induces a sort of quantum friction that diminishes the efficiency. We also find regions of parameters where the effect is so strong that the machine can no longer function as an engine since the work that would be produced is completely consumed by the quantum friction. However, this effect can be avoided for some particular temporal evolutions of the boundary conditions that do not change the occupation number of the modes in the cavity, leading to a highly improved efficiency.

description: Despite strong evidence for the existence of spillover effects in consumer patronage between anchor stores and other less dominant stores in shopping malls, research on spillover patronage antecedents and its underlying formation mechanisms appears to be sparse. The current study explores the effect of the difference between perceived store image for anchor versus non-anchor stores on cross-shop consumer behavior drawing from theories of spillover shopping and retail patronage. Employing a questionnaire survey and laboratory experiments to obtain data on shopping experiences, this study shows that the smaller the image gap between an anchor store and non-anchor stores, the greater the likelihood of non-anchor store patronage by customers originally attracted to the anchor store. This study also finds that when customers attracted by the anchor store experience greater self-image congruity with non-anchor stores, the extent of spillover patronage increases, while this happens irrespective of whether they engage or do not engage in purchase in the anchor store. This study provides a viable theoretical basis for facilitating decision-making in both planning and design of effective retail agglomerations.

description: High energy Heavy Ion Collisions (HIC) are studied in order to access nuclear matter properties at high density. Particular attention is paid to the selection of observables sensitive to the poorly known symmetry energy at high baryon density, of large fundamental interest, even for the astrophysics implications. Using fully consistent transport simulations built on effective theories we test isospin observables ranging from nucleon/cluster emissions to collective flows (in particular the elliptic, squeeze out, part). The effects of the competition between stiffness and momentum dependence of the Symmetry Potential on the reaction dynamics are thoroughly analyzed. In this way we try to shed light on the controversial neutron/proton effective mass splitting at high baryon and isospin densities. New, more exclusive, experiments are suggested.

Entanglement vs. gap for one-dimensional spin systems

description: We study the relationship between entanglement and spectral gap for local Hamiltonians in one dimension. The area law for a one-dimensional system states that for the ground state, the entanglement of any interval is upper-bounded by a constant independent of the size of the interval. However, the possible dependence of the upper bound on the spectral gap Delta is not known, as the best known general upper bound is asymptotically much larger than the largest possible entropy of any model system previously constructed for small Delta. To help resolve this asymptotic behavior, we construct a family of one-dimensional local systems for which some intervals have entanglement entropy which is polynomial in 1/Delta, whereas previously studied systems, such as free fermion systems or systems described by conformal field theory, had the entropy of all intervals bounded by a constant times log(1/Delta).

Expressing Surprise A Cross-Linguistic Description of Mirativity

description: As I have argued elsewhere (Mocini 2009; 2011; 2013), emotions play a decisive role in
promotional discourse. The power of logical argument may not be sufficient to
convince customers. For this reason, writers or speakers usually appeal to the
audience’s emotional response to achieve persuasion. Ekman (1999) claims that
surprise is one of the basic universal emotions, and only the basic emotions are the
real emotions.1 Following DeLancey (1997; 2001) and other researchers (Dickinson
2000; Aikhenvald 2004; Peterson 2010, 2013), we use the term mirativity to refer to the
semantic category employed to mark the fact that some information is new or
surprising.

title: The Effect of Implementing a Weight Loss Program on Participant Attendance, Club Usage, and Gym Membership Attrition
Creators: name: Haymond, Stephanie Bonkemeyer
Publisher: name: Utah State University
Year: 2013

description: The purpose of this research study was to evaluate the effect of a weight loss program on individual participant attendance, total club usage and membership attrition. This retrospective study involved a fitness gym located in Utah County, Utah with a total membership of 1,100. The number of clients participating in the weight loss program between December 2011 and May 2012 was 36 (32 females and 4 males). A total of 11 clients were analyzed for the individual attendance data as this analysis was limited to only those clients who were gym members one year prior to the implementation of the program. A comprehensive weight loss program was implemented in the gym between December 2011 and May 2012. Six months of participant attendance, total club usage, and gym attrition data was gathered before and after implementation of the program. The average monthly attendance before the program implementation was 7.0 + 7.93 visits, while the average monthly attendance after the program implementation was 16.3 + 11.47 visits (an increase of 132%). This suggests that implementing a weight loss program in a gym can increase individual participant attendance. Club usage decreased and attrition increased after implementing the weight loss program, however, the changes were not statistically significant (P > 0.05).

description: Purpose: This paper aims to explore marketing practices related to online halal maternity wear by examining the characteristics of halal maternity wear promoted to Muslim women (Muslimah) and how these differ between sponsoring websites. Design/methodology/approach: A qualitative content analysis of 24 websites promoting halal maternity wear to pregnant customers was undertaken. Findings: Several issues related to the availability and promotion of halal maternity wear online, particularly when addressing the needs of Western Muslim women, were found. Successful marketing solutions to the problems of halal maternity wear require solving a number of tensions arising at the intersections of the following distinctions: mahram versus non-mahram settings, crude versus stylish fashion and the normative perceptions of immodesty versus modesty. Practical implications: Careful research and attention need to be taken before promoting and targeting products as appropriate for Muslimah maternity wear. Those brands that display the requisite skills and knowledge necessary to determine whether a product meets the needs of modesty, fashionability and local climate/weather conditions in their maternity lines have much to gain from the Muslimah maternity market. Social implications: The availability of maternity wear that makes Muslimah feel comfortable and satisfied with their appearance will contribute to a positive pregnancy body image. Positive pregnancy body image is associated with positive pre and postnatal infant attachment by the mother, which in turn leads to beneficial outcomes for mother and baby. Originality/value: Research to date has focused on Islamic fashion in general, with a dearth of research on Islamic maternity wear. This paper addresses the gap by focusing on maternity wear and associated marketing practices, from the Islamic point of view.

description: Aims. This work reports radiative transition rates and electron impact excitation collision strengths for levels of the 3s23p, 3s3p2, 3s24s, and 3s23d configurations of Siii. Methods. The radiative data were computed using the Thomas-Fermi-Dirac-Amaldi central potential, but with the modifications introduced by Bautista (2008) that account for the effects of electron-electron interactions. We also introduce new schemes for the optimization of the variational parameters of the potential. Additional calculations were carried out with the Relativistic Hartree-Fock and the multiconfiguration Dirac-Fock methods. Collision strengths in LS-coupling were calculated in the close coupling approximation with the R-matrix method. Then, fine structure collision strengths were obtained by means of the intermediate-coupling frame transformation (ICFT) method which accounts for spin-orbit coupling effects. Results. We present extensive comparisons between the results of different approximations and with the most recent calculations and experiment available in the literature. From these comparisons we derive a recommended set of gf- values and radiative transition rates with their corresponding estimated uncertainties. We also study the effects of different approximations in the representation of the target ion on the electron-impact collision strengths. Our most accurate set of collision strengths were integrated over a Maxwellian distribution of electron energies and the resulting effective collision strengths are given for a wide range of temperatures. Our results present significant differences from recent calculations with the B-spline non-orthogonal R-matrix method. We discuss the sources of the differences.

description: We present experimental evidence that a bubble moving in a fluid in which a well-chosen acoustic noise is superimposed can be significantly slowed down for moderate acoustic pressures. Through mean velocity measurements, we show that a condition for this effect to occur is for the acoustic noise spectrum to match or overlap the bubble's fundamental resonant mode. By rendering the bubble's oscillations and translational movements using high speed video, we evidence that radial oscillations have no effect on the mean velocity, while above a critical sound pressure threshold, Faraday waves are triggered and are responsible for the bubble's drag increase.

description: This paper extends the modern theory of tunneling transport to finite temperatures. The extension enables applications to molecular electronic devices connected to semiconducting leads. The paper presents an application of the theory to molecular devices made of alkyl chains connected to silicon nano-wires, mapping their transport characteristics as functions of temperature and alkyl chain's length. Based on these calculations and on the analytic theory, it is found that the tunneling decay constant is determined not by the Fermi level, but by the edge of the valence or conductance band, whichever is closer to the Fermi level. Further insight is provided by mapping the evanescent transport channels of the alkyl chains and few other physical quantities appearing in the analytic formula for conductance. A good qualitative agreement with the experimental data is obtained.

description: BACKGROUND: COVID-19 vaccine uptake among individuals with disabilities is crucial for safeguarding their health and well-being. However, the extent of vaccine uptake among this group remains largely unknown in low- and middle-income countries. This study aims to assess the COVID-19 vaccine uptake among persons with functional difficulty, disability and/or comorbidity in Bangladesh and their associated factors. METHODS: Data from 9,370 respondents extracted from the 2021 National Household Survey on Persons with Disability were analysed. The outcome variable was the uptake of at least one dose of the COVID-19 vaccine (yes, no). Key explanatory variables included the presence of disability (yes, no), comorbidity (yes, no), and both comorbidity and disability (yes, no) among persons with functional difficulty. The relationship between the outcome and explanatory variables was determined using mixed-effects multilevel logistic regressions adjusted for covariates. RESULTS: The overall uptake of at least one dose of the COVID-19 vaccine among persons with functional difficulty was 57.37%, among persons with functional difficulty and disability was 48.63% and among persons with functional difficulty and single (57.85%) or multi-comorbidity (60.37%). Compared to the respondents with functional difficulty only, the adjusted odds ratio (aOR) of not receiving any dose of the COVID-19 vaccine for individuals with both functional difficulty and disability was 1.37 (95% CI, 1.22-1.53), and for individuals with functional difficulty, disability and one or more comorbid conditions was 1.30 (95% CI, 1.15-1.47). The aOR of receiving at least one dose of the COVID-19 vaccine among individuals with functional difficulty and one or more comorbid conditions was significantly higher than among those with functional difficulty only. CONCLUSION: In Bangladesh, COVID-19 vaccine uptake was relatively low among individuals with disabilities. The existing COVID-19 vaccine rollout programs and similar future programs should prioritise individuals with disabilities and include targeted strategies to reach them.

description: Recently, we have shown that scalar spectra with lower power on large scales and certain other features naturally occur in {\it punctuated inflation}, i.e. the scenario wherein a brief period of rapid roll is sandwiched between two stages of slow roll inflation. Such spectra gain importance due to the fact that they can lead to a better fit of the observed Cosmic Microwave Background (CMB) anisotropies, when compared to the conventional, featureless, power law spectrum. In this paper, with examples from the canonical scalar field as well as the tachyonic models, we illustrate that, in punctuated inflation, a drop in the scalar power on large scales is {\it always} accompanied by a rise in the tensor power and, hence, an even more pronounced increase in the tensor-to-scalar ratio $r$ on these scales. Interestingly, we find that $r$ actually {\it exceeds well beyond unity} over a small range of scales. {\it To our knowledge, this work presents for the first time, examples of single scalar field inflationary models wherein $r\gg 1$.} This feature opens up interesting possibilities. For instance, we show that the rise in $r$ on large scales translates to a rapid increase in the angular power spectrum, $C_{\ell}^{\rm BB}$, of the B-mode polarization of the CMB at the low multipoles. We discuss the observational implications of these results.

title: The Effects of Instruction on Self-Determination on Transition Students' Levels of Goal-Setting, Goal Expression and Action
Creators: name: Sorensen, Scott Charles
Publisher: name: Utah State University
Year: 2013

description: Students with disabilities in transition from school to adulthood often experience problems with self-determination skills, especially goal-related skills (e.g., goal setting, expression, and taking action). Instruction in these skills is needed. This project examined the effect of instructing portions of the self-determination intervention Whose Future is it Anyway? (WFA) dealing with goal-related skills and its effect on goal setting, expressing, and taking action. Participants included five students with disabilities in a transition program ages 18 to 21. Procedures involved a pretest using the ChoiceMaker Assessment and the Arc Scale, followed by the implementation of the WFA intervention, and posttests using the same two assessments as well as a rating scale completed by teachers independent of the study administered immediately following the intervention. The measures of participants' goal-setting, expression, and taking action as measured by teachers independent of the study increased using the ChoiceMaker assessment and Teacher's Scale showed a degree of growth during the intervention. The student-reported measures using the Arc scale did not show an increase due to a poor match between the curriculum and the researcher's choice of questions from the scale. The results that were obtained have implications in terms of knowing that goal-related skills can be increased through the use of self-determination interventions. These finding may have implications for additional research and curriculum usage in high schools.
Extra Higgs bosons in ttbar production at the LHC

description: The top quark has a large Yukawa coupling with the Higgs boson. In the usual extensions of the standard model the Higgs sector includes extra scalars, which also tend to couple strongly with the top quark. Unlike the Higgs, these fields have a natural mass above 2m_t, so they could introduce anomalies in ttbar production at the LHC. We study their effect on the ttbar invariant mass distribution at sqrt{s}=7 TeV. We focus on the bosons (H,A) of the minimal SUSY model and on the scalar field (r) associated to the new scale f in Little Higgs (LH) models. We show that in all cases the interference with the standard amplitude dominates over the narrow-width contribution. As a consequence, the mass difference between H and A or the contribution of an extra T-quark loop in LH models become important effects in order to determine if these fields are observable there. We find that a 1 fb^{-1} luminosity could probe the region tan beta \le 3 of SUSY and v/(sqrt{2}f) \ge 0.3 in LH models.

title: Optimization of Polyhydroxybutyrate Production in Recombinant Escherichia Coli Through Metabolic Modeling and Simulation
Creators: name: Heshiki, Yoshitaro
Publisher: name: Utah State University
Year: 2013

description: The objective of this study is to optimize the growth media and genes to maximize PHB production computer simulations, and to evaluate the simulation results through experiments. In order to achieve this objective, the metabolism of E. coli that produces PHB was modeled using the existing E. coli genome-scale metabolic networks. To identify the best additional nutrient for PHB production, carbon sources, minerals, amiano acids, nitrogen sources, and sulfur sources were examined by production potential analysis. Strain design was conducted to find the unwanted reactions to overexpress PHB synthesis pathway.

An area law for the entropy of low-energy states

description: It is often observed in the ground state of spatially-extended quantum systems with local interactions that the entropy of a large region is proportional to its surface area. In some cases, this area law is corrected with a logarithmic factor. This contrasts with the fact that in almost all states of the Hilbert space, the entropy of a region is proportional to its volume. This paper shows that low-energy states have (at most) an area law with the logarithmic correction, provided two conditions hold: (i) the state has sufficient decay of correlations, (ii) the number of eigenstates with vanishing energy-density is not exponential in the volume. These two conditions are satisfied by many relevant systems. The central idea of the argument is that energy fluctuations inside a region can be observed by measuring the exterior and a superficial shell of the region.

description: The development of large-area homogeneous photo-detectors with sub-millimeter path lengths for direct Cherenkov light and for secondary-electrons opens the possibility of large time-of-flight systems for relativistic particles with resolutions in the pico-second range. Modern ASIC techniques allow fast multi-channel front-end electronics capable of sub-pico-second resolution directly integrated with the photo-detectors. However, achieving resolution in the pico-second range requires a precise knowledge of the signal generation process in order to understand the pulse waveform, the signal dynamics, and the noise induced by the detector itself, as well as the noise added by the processing electronics. Using the parameters measured for fast photo-detectors such as micro-channel plates photo-multipliers, we have simulated and compared the time-resolutions for four signal processing techniques: leading edge discriminators, constant fraction discriminators, multiple-threshold discriminators and pulse waveform sampling.

description: With the advances in virtual and augmented reality, gaming applications, and entertainment, certain indoor scenarios will require vastly higher capacity than what can be delivered by 5G. In this paper, we focus on massive MIMO for indoor environments. We provide a case study of the distributed deployment of the antenna elements over the walls of a room and not restricting the antenna separation to be half the wavelength. This is a new paradigm of massive MIMO antenna deployment, introduced under the name RadioWeaves. We investigate different antenna deployment scenarios in line of sight communication. We observe that the RadioWeaves deployment can spatially separate users much better than a conventional co-located deployment, which outweighs the losses caused by grating lobes and thus saves a lot on transmit power. Through simulations, we show that the RadioWeaves technology can provide high rates to multiple users by spending very little power at the transmitter compared to a co-located deployment.
