description: Quantum metrology has an important role in the fields of quantum optics and quantum information processing. Here we introduce a kind of non-Gaussian state, Laguerre excitation squeezed state as input of traditional Mach-Zehnder interferometer to examine phase estimation in realistic case. We consider the effects of both internal and external losses on phase estimation by using quantum Fisher information and parity detection. It is shown that the external loss presents a bigger effect than the internal one. The phase sensitivity and the quantum Fisher information can be improved by increasing the photon number and even surpass the ideal phase sensitivity by two-mode squeezed vacuum in a certain region of phase shift for realistic case.

description: We analyze the performance of a quantum repeater protocol based on single trapped ions. At each node, single trapped ions embedded into high finesse cavities emit single photons whose polarization is entangled with the ion state. A specific detection of two photons at a central station located half-way between two nodes heralds the entanglement of two remote ions. Entanglement can be extended to long distances by applying successive entanglement swapping operations based on two-ion gate operations that have already been demonstrated experimentally with high precision. Our calculation shows that the distribution rate of entanglement achievable with such an ion-based quantum repeater protocol is higher by orders of magnitude than the rates that are achievable with the best known schemes based on atomic ensemble memories and linear optics. The main reason is that for trapped ions the entanglement swapping operations are performed deterministically, in contrast to success probabilities below 50 percent per swapping with linear optics. The scheme requires efficient collection of the emitted photons, which can be achieved with cavities, and efficient conversion of their wavelength, which can be done via stimulated parametric down-conversion. We also suggest how to realize temporal multiplexing, which offers additional significant speed-ups in entanglement distribution, with trapped ions.

description: We propose a geographic and spatio-temporal information based distributed cooperative positioning (GSTICP) algorithm for wireless networks that require three-dimensional (3D) coordinates and operate in the line-of-sight (LOS) and nonline-of-sight (NLOS) mixed environments. First, a factor graph (FG) is created by factorizing the a posteriori distribution of the position-vector estimates and mapping the spatial-domain and temporal-domain operations of nodes onto the FG. Then, we exploit a geographic information based NLOS identification scheme to reduce the performance degradation caused by NLOS measurements. Furthermore, we utilize a finite symmetric sampling based scaled unscented transform (SUT) method to approximate the nonlinear terms of the messages passing on the FG with high precision, despite using only a small number of samples. Finally, we propose an enhanced anchor upgrading (EAU) mechanism to avoid redundant iterations. Our GSTICP algorithm supports any type of ranging measurement that can determine the distance between nodes. Simulation results and analysis demonstrate that our GSTICP has a lower computational complexity than the state-of-the-art belief propagation (BP) based localizers, while achieving an even more competitive positioning performance.

title: Fear of Crime and Perceptions of Law Enforcement Among American Youth
Creators: name: Bayley, Bruce K.
Publisher: name: Utah State University
Year: 2002

description: Fear of crime and the public's satisfaction with police has been a focus of criminologists for a number of years. Most studies, however, have focused on the general population as a whole. What is not known is how fearful American youth are of the crime in their neighborhoods and how they perceive those in law enforcement. The purpose of this study was to explore this subgroup of the population and to begin the investigation of youths' fear of crime and their perceptions of law enforcement.
Using a national sample of 1,897 youth ages 16-25 collected from 12 cities throughout the United States, data were analyzed to explore the strength of demographic and community variables as they related to youths' fear of crime and perceptions of law enforcement.
Results for fear of crime indicate that in general, American youth are not very fearful of crime in their neighborhoods. Older youth (18-25) tended to be more fearful than younger youth (16-17), females were more fearful than males, married youth were more fearful than non-married youth, youth living in the Northeast census region were the most fearful of the four census regions, and all non-White youth were more fearful of crime when compared to Whites. Youths' overall satisfaction with police indicated that in general, American youth were satisfied with police in their neighborhoods, with White youth and those youth with some college education being most satisfied with police.
When addressing the variance explained by demographic and community variables, youths' perceptions regarding their quality of life accounted for the most variance in both fear of crime and satisfaction with police. The strength of this predictor variable was so strong in fact, that other demographic and community variables were negligible by comparison.

description: We performed non-local electrical measurements of a series of Py/Cu lateral spin valve devices with different Cu thicknesses. We show that both the spin diffusion length of Cu and the apparent spin polarization of Py increase with Cu thickness. By fitting the results to a modified spin-diffusion model, we show that the spin diffusion length of Cu is dominated by spin-flip scattering at the surface. In addition, the dependence of spin polarization of Py on Cu thickness is due to a strong spin-flip scattering at the Py/Cu interface.
Professional codes of ethics : a study of the judicial viability of the codes of ethics of medicine, social work and librarianship
Creators: name: Brown, Rosemary
Publisher: name: University of British Columbia
Year: 2011

description: Traditionally, one of the major characteristics of established professions such as medicine and law has been the possession of a Code of Ethics. The last three decades have seen the formulation of Codes of Ethics by many new professions and semi-professions as well as by many of the service occupations. In view of the intense concern of these professions, semi-professions and service occupations with the formation of codes of ethics, we set out to examine the codes of three professions to ascertain their functional significance both to the professions themselves and to the public. The rationale for the choice of the three professions of Medicine, Social Work, and Librarianship lay in their being professions whose codes of ethics were in different stages of development. A theoretical framework formulated in the first chapter was used in the following three chapters to examine the judicial viability of the codes of ethics of these professions. As main features of this analysis, we considered the formulation, promulgation, administration, review and revision procedures, jurisdiction, and implications for social policy of the codes. On the basis of the analysis and discussion of the codes of ethics studied we drew the conclusion that many of the existing codes are, to a great extent, deplorably non-specific and even rhetorical. It would therefore seem to be desirable that some measures should be taken to improve the judicial viability of these Codes; and we have made a number of recommendations calculated to achieve this end.

title: Maternal Involvement in Preschoolers' Sexuality Education: A Comparison of Single and Married Mothers
Creators: name: Sandweg, Ginger S.
Publisher: name: Utah State University
Year: 2003

description: This study examined the responses to a sexuality education questionnaire completed by 30 single mothers and 43 married mothers with preschool-aged children. Chi-square analyses were used to examine differences between married mothers and single mothers; mothers of males and mothers of females; and married mothers of males, married mothers of females, single mothers of males and single mothers of females. Age at which their preschool children first exhibited behaviors, frequency of that behavior, and comfort level of mothers' responses to those behaviors were addressed for each topic: male-female differences, reproduction and birth, privacy or modesty, taboo or obscene words, genital play, and sexual exploration play.
Very few statistically significant differences were apparent in the comparisons that were made. Married mothers were more comfortable than single mother in responding to their child's questions about male-female differences and their child's use of taboo or obscene words. In addition, some interesting trends emerged. For instance, mothers tended to ex press more comfort when responding to hypothetical situations than when responding to actual situations. Questions about male-female differences, reproduction and birth, and privacy or modesty were responded to more frequently than questions about taboo or obscene words, genital play, or sexual exploration play. Moreover, maternal observation of behaviors that appeared to be more sensitive (and less comfortable, such as taboo or obscene words, genital play, and sexual exploration play) was lower than observation of less sensitive behaviors (male-female differences, privacy or modesty, and reproduction and birth). The implications of this study and directions for future research are discussed.

title: An Assessment of Marital Satisfaction, Marital Adjustment, and Problematic Areas During the First Few Months of Marriage Among a Sample of Newlyweds in Utah
Creators: name: Schramm, David G.
Publisher: name: Utah State University
Year: 2003

description: A self-selected sample of232 newlywed husbands and wives in Utah was surveyed to assess marital satisfaction, marital adjustment, and problematic areas during the first few months of marriage. The study utilized the Kansas Marital Satisfaction Scale (KMSS) and the Revised Dyadic Adjustment Scale (RDAS), in addition to a list of30 potential problematic areas created by Creighton University to measure these constructs.
Although the majority of the newlyweds in this sample were fairly satisfied and well adjusted, II% of both husbands and wives scored in the distressed range on the RDAS, signaling that the first few months of marriage can be a time of tension and strain for some couples.
Many demographic and interactional history variables were tested as to how well they predict marital satisfaction and marital adjustment among newlywed husbands and wives, and only husbands' religiosity and whether a child was brought into the marriage were significant predictors of both husbands' and wives' marital satisfaction and marital adjustment scores. The most problematic areas for both husbands and wives were balancing employment and marriage and the presence of debt brought into marriage.
When regression analyses were carried out that included demographics and problematic areas, a high degree of religiosity among husbands and wives was the strongest and most consistent predictor of marital satisfaction and marital adjustment. However, it was the problematic areas in the relationship that accounted for the majority of the variance in marital satisfaction and marital adjustment scores, rather than the demographic variables alone. Thus, it appears that the demographic variables affect the likelihood that various marital problems would arise, which, in tum, increased the likelihood of lower marital satisfaction and marital adjustment among both husbands and wives.
These findings suggest that educators and others helping engaged couples and newlyweds should focus more on the problematic areas that often arise in marriage, which are noted in this study, rather than the demographic and interactional characteristics couples bring to the marriage. Moreover, it is suggested that marriage education strategies be centered on engaged and newlywed couples to assist them in adjusting to the new roles and expectations they encounter.

description: Machine learning frameworks based on correlations of interatomic positions begin with a discretized description of the density of other atoms in the neighbourhood of each atom in the system. Symmetry considerations support the use of spherical harmonics to expand the angular dependence of this density, but there is as yet no clear rationale to choose one radial basis over another. Here we investigate the basis that results from the solution of the Laplacian eigenvalue problem within a sphere around the atom of interest. We show that this generates the smoothest possible basis of a given size within the sphere, and that a tensor product of Laplacian eigenstates also provides the smoothest possible basis for expanding any higher-order correlation of the atomic density within the appropriate hypersphere. We consider several unsupervised metrics of the quality of a basis for a given dataset, and show that the Laplacian eigenstate basis has a performance that is much better than some widely used basis sets and is competitive with data-driven bases that numerically optimize each metric. In supervised machine learning tests, we find that the optimal function smoothness of the Laplacian eigenstates leads to comparable or better performance than can be obtained from a data-driven basis of a similar size that has been optimized to describe the atom-density correlation for the specific dataset. We conclude that the smoothness of the basis functions is a key and hitherto largely overlooked aspect of successful atomic density representations.

description: In this paper, we derive a $T\bar{T}$ deformed soft graviton theorem in the context of celestial holography. As a concrete example, it illustrates that a two-dimensional irrelevant deformation can be applied to a four-dimensional theory at the level of amplitudes. We argue that the $T\bar{T}$ deformation has a close relation to the loop-correction from the amplitude side which could provide an alternative way to construct an ultraviolet complete quantum theory of gravity.

title: Intermediate Trainee Perspectives of Family Therapy Skills
Creators: name: Benson, Margo
Publisher: name: Utah State University
Year: 2004

description: Marriage and family therapy training involves the development of therapy skills that lead to effective treatment, and the family therapy literature recognizes the importance of skill development in training. The training literature dealing with specific skills most often refers to beginning-level skills and obtains data largely from supervisors and trainers. Intermediate-level skills appear to be overlooked and no apparent attention is given from the perspective of trainees.
This research examined the perspectives of trainees concerning family therapy skills at the intermediate level. Intermediate trainee perspectives were compared with the perspectives of their supervisors. Comparisons were also made with perspectives of beginning students. The findings indicate that intermediate trainees consider all the skills defined by their supervisors as important, with some differences among the groups in the types of skills preferred. Intermediate trainees continue to value the self attributes and joining skills preferred by beginning students as they make the transition to the professional level, where case management and professionalism skills become more important.

description: The concept of "dyadotorus" was recently introduced to identify in the Kerr-Newman geometry the region where vacuum polarization processes may occur, leading to the creation of $e^--e^+$ pairs. This concept generalizes the original concept of "dyadosphere" initially introduced for Reissner-Nordström geometries. The topology of the axially symmetric dyadotorus is studied for selected values of the electric field and its electromagnetic energy is estimated by using three different methods all giving the same result. It is shown by a specific example the difference between a dyadotorus and a dyadosphere. The comparison is made for a Kerr-Newman black hole with the same total mass energy and the same charge to mass ratio of a Reissner-Nordström black hole. It turns out that the Kerr-Newman black hole leads to larger values of the electromagnetic field and energy when compared to the electric field and energy of the Reissner-Nordström one. The significance of these theoretical results for the realistic description of the process of gravitational collapse leading to black hole formation as well as the energy source of gamma ray bursts are also discussed.

title: Building a Bridge Between Graduation and Marriage and Family Therapy Core Competency
Creators: name: Graves, Todd
Publisher: name: Utah State University
Year: 2005

description: Most mental health professional organizations are establishing core competencies standards, which are the basic skills that practitioners are expected to possess. The core competency movement originated from concerns about the abilities of clinicians to provide competent service to clients. The American Association for Marriage and Family Therapy (AAMFT) recently established the core competencies that each marriage and family therapist 's skill s should be measured by and that may lead to changes in education and training.
This research examined the perspectives of AAMFT-approved supervisors to determine how they see their trainees' performances compared to the core competency standards. Comparisons were made between the desired levels of performance reported by supervisors and the estimated performance level of the trainees. Results were tabulated and reported as mean scores and frequencies The result is a better understanding of what approved supervisors hope that trainees will be able to do upon graduation

description: The understanding of antiferromagnetic domain walls, which are the interface between domains with different Néel order orientations, is a crucial aspect to enable the use of antiferromagnetic materials as active elements in future spintronic devices. In this work, we demonstrate that in antiferromagnetic NiO/Pt bilayers circular domain structures can be generated by switching driven by electrical current pulses. The generated domains are T-domains, separated from each other by a domain wall whose spins are pointing toward the average direction of the two T-domains rather than the common axis of the two planes. Interestingly, this direction is the same for the whole circular domain indicating the absence of strong Lifshitz invariants. The domain wall can be micromagnetically modeled by strain distributions in the NiO thin film induced by the MgO substrate, deviating from the bulk anisotropy. From our measurements we determine the domain wall width to have a full width at half maximum of $Δ= 98 \pm 10$ nm, demonstrating strong confinement.

description: We study the backreaction problem in a mechanism of magnetogenesis from inflation. In usual analysis, it has been assumed that the backreaction due to electromagnetic fields spoils inflation once it becomes important. However, there exists no justification for this assumption. Hence, we analyze magnetogenesis from inflation by taking into account the backreaction. On the contrary to the naive expectation, we show that inflation still continues even after the backreaction begins to work. Nevertheless, it turns out that creation of primordial magnetic fields is significantly suppressed due to the backreaction.

description: An essential ingredient in kinematic dynamo models is the velocity field within the solar convection zone. In particular, the differential rotation is now well constrained by helioseismic observations. Helioseismology also gives us information about the depth-dependence of the meridional circulation in the near-surface layers. The typical velocity inputs used in solar dynamo models, however, continue to be an analytic fit to the observed differential rotation and a theoretically constructed meridional flow profile that matches only the peak flow speed at the surface. Here we take the first steps towards realistic helioseismic data assimilation, by presenting methodologies for constructing differential rotation and meridional circulation profiles that more closely conform to the observational constraints currently available. We also present simulations driven by the assimilated rotation and four plausible profiles for the internal meridional circulation -- all of which match the helioseismically inferred near-surface depth-dependence, but whose magnitudes are made to vary. We discuss how the results compare with those that are driven by purely analytic fits. Our results indicate that the latitudinal shear of the rotation in the bulk of the solar convection zone plays a more important role, than either the tachocline or surface radial shear, in the induction of toroidal field. We also find that it is the speed of the equatorward counter-flow in the meridional flow at the base of the convection zone, and not how far into the radiative interior it penetrates, that primarily determines the dynamo cycle period. Given that improved helioseismic constraints are expected to be available in the future, our analysis lays the basis for assimilating these data within dynamo models.
title: Relationship Between Infant Reactivity and Maternal Emotional Well-Being During the Early Postpartum Period at Two Points in Time
Creators: name: Hansen, Karen Udy
Publisher: name: Utah State University
Year: 2005

description: This study examined the relationship between infants' reactivity and mothers' emotionality during the early postpartum period, specifically during the first days of life and again by three months of age. The Clinical Neonatal Behavioral Scale (CLNBAS) was used to evaluate the infants. The mothers were evaluated at the same time by responding to questions on the Edinburgh Postnatal Depression Scale (EPDS).
Forty-six mother-infant dyads were recruited from the Logan Regional Hospital childbirth classes for first-time parents. Minimum criteria for participation were that the mother must be married, be at least 18 years of age, have at least a high school education, with the infant must having a minimum APGAR score of 7 on the second APGAR evaluation and being the firstborn. There were 27 male and 19 female infants in the study.
After the initial sign-up for participation, the mothers were contacted prior to the baby's due date and arrangements were made to visit them for the first evaluation in the home. At the time of the first evaluation (TI ), a date was set for the second evaluation (T2).
Several aspects of the mother-infant interactive process and the relationship between mothers' emotionality and the infants' reactivity were noted in the collected data. This study focused mainly on the infants' reactivity to the social emotional items of the CLNBAS in relationship to the mothers' EPDS scores or level of emotionality, but other CLNBAS areas were also studied.
Infants' reactivity Tl and mothers' emotionality T2 had a statistically significant relationship for CLNBAS items, "response to face and voice" and "tracking the red ball." Mothers previously diagnosed with depression scored higher on the EPDS Tl and T2 than mothers not previously diagnosed as depressed, and their infants scored lower on the CLNBAS when compared to the infants whose mothers were not previously diagnosed with depression.

description: We study lepton flavor violating (LFV) $B$ decays in a general two Higgs doublet model with sub-TeV exotic scalars. Two different parameter spaces are explored: one dominated by extra top Yukawa coupling $ρ_{tt}$, the other by LFV couplings relevant for the muon $g-2$ anomaly. In the first case, flavor constraints such as $\ell \to \ell^\primeγ$, $h \to \ell\ell^\prime$ imply LFV $B$ decays are far below experimental sensitivities. The second case needs to be close to the alignment limit, but $B_q \to τμ$ and $B \to (K, π) τμ$ rates can lie within the sensitivities of Belle II and LHCb Upgrade II. Neutral $B$ meson mixings and $B,\, K,\, π\to \ell ν$ decays provide important flavor constraints on parameter space. $B$ decays involving $e$-$τ$ violation are constrained by $μ\to e$ processes.

title: A Survey to Determine the Incidence of Antibodies Against Q Fever in Persons in Utah
Creators: name: Blank, Carl H.
Publisher: name: Utah State University
Year: 1957

description: Q fever, as a recognized clinical entity, is often referred to as a new disease of man. Pneumonic in character but lacking clean-cut pathognomic characteristics, in all probability Q fever has been confused in the past with influenza, primary atypical pneumonia (1), or included as an undifferentiated disease under "virus pneumonia." Geddis Smith (2), writing in 1941, stated: ••• influenza, pneumonia, "pleurisy", or bronchitis • • • form a nosological jungle in which bacteria and viruses roam at will, despoiling the human race and defying both classification and control. Symptoms overlap and no one knows how many different diseases lurk behind them..

description: Pasture is considered one of our most important agricultural crops, contributing more than one third of all feed consumed by livestock in the United States. High quality pasture has been recognized to be highly important in efficient milk production. It has been shown, however, that good pasture must be supplemented by concentrates if' milk production is to be maintained at a high level.

description: A well-adapted visible and infrared spectrograph has been developed for the SNAP (SuperNova/Acceleration Probe) experiment proposed for JDEM. The instrument should have a high sensitivity to see faint supernovae but also a good redshift determination better than 0.003(1+z) and a precise spectrophotometry (2%). An instrument based on an integral field method with the powerful concept of imager slicing has been designed. A large prototyping effort has been performed in France which validates the concept. In particular a demonstrator reproducing the full optical configuration has been built and tested to prove the optical performances both in the visible and in the near infrared range. This paper is the first of two papers. The present paper focus on the wavelength measurement while the second one will present the spectrophotometric performances. We adress here the spectral accuracy expected both in the visible and in the near infrared range in such configuration and we demonstrate, in particular, that the image slicer enhances the instrumental performances in the spectral measurement precision by removing the slit effect. This work is supported in France by CNRS/INSU/IN2P3 and by the French spatial agency (CNES) and in US by the University of California.

description: A hyperbolic lattice allows for any $p$-fold rotational symmetry, in stark contrast to a two-dimensional crystalline material, where only twofold, threefold, fourfold or sixfold rotational symmetry is permitted. This unique feature motivates us to ask whether the enriched rotational symmetry in a hyperbolic lattice can lead to any new topological phases beyond a crystalline material. Here, by constructing and exploring tight-binding models in hyperbolic lattices, we theoretically demonstrate the existence of higher-order topological phases in hyperbolic lattices with eight-fold, twelve-fold, sixteen-fold or twenty-fold rotational symmetry, which is not allowed in a crystalline lattice. Since such models respect the combination of time-reversal symmetry and $p$-fold ($p=$8, 12, 16 or 20) rotational symmetry, $p$ zero-energy corner modes are protected. For the hyperbolic \{8,3\} lattice, we find a gapped, a gapless and a reentrant gapped higher-order topological hyperbolic phases. The reentrant phase arises from finite-size effects, which open the gap of edge states while leave the gap of corner modes unchanged. Our results thus open the door to studying higher-order topological phases in hyperbolic lattices.

description: Gamma-ray binaries have been uncovered as a new class of Galactic objects in the very high energy sky (> 100 GeV). The three systems known today have hard X-ray spectra (photon index ~ 1.5), extended radio emission and a high luminosity in gamma-rays. Recent monitoring campaigns of LSI +61 303 in X-rays have confirmed variability in these systems and revealed a spectral hardening with increasing flux. In a generic one-zone leptonic model, the cooling of relativistic electrons accounts for the main spectral and temporal features observed at high energy. Persistent hard X-ray emission is expected to extend well beyond 10 keV. We explain how Simbol-X will constrain the existing models in connection with Fermi Space Telescope measurements. Because of its unprecedented sensitivity in hard X-rays, Simbol-X will also play a role in the discovery of new gamma-ray binaries, giving new insights into the evolution of compact binaries.

description: We prove that the electromagnetic material parameters are uniquely determined by boundary measurements for the time-harmonic Maxwell equations in certain anisotropic settings. We give a uniqueness result in the inverse problem for Maxwell equations on an admissible Riemannian manifold, and a uniqueness result for Maxwell equations in Euclidean space with admissible matrix coefficients. The proofs are based on a new Fourier analytic construction of complex geometrical optics solutions on admissible manifolds, and involve a proper notion of uniqueness for such solutions.

description: We study the online detection by gallium capture of mono-energetic neutrinos produced by a $^{51}$Cr radioactive source in a scintillation experiment. We find that cerium-doped gadolinium aluminum gallium garnet (GAGG) is a suitable scintillator which contains about 21% of gallium per weight and has a high mass density and light yield. Combined with a highly efficient light detection system this allows tagging of the subsequent germanium decay and thus a clean distinction of gallium capture and elastic neutrino electron scattering events. With 1.5 tons of scintillator and 10 source runs of 3.4MCi, each, we obtain about 760 gallium capture events with a purity of 85% and 680,000 neutrino electron scattering events, where the latter provide a precise normalization independent of any nuclear physics. This configuration would allow to test the gallium anomaly at more than $5σ$ in an independent way.

description: The emergent phases of strongly correlated spin-1/2 Fermi gases of Rydberg dressed atoms in a one dimensional optical lattice are theoretically investigated. At weak coupling a bosonization description is used to demonstrate the ability to drive alternating quantum phase transitions between distinct Luttinger liquids. At strong coupling the ground state develops non-trivial phase separation exhibiting Luttinger liquid ''puddles'' separated by magnetic domain walls due to the interplay of the incommensurate filling and the Rydberg core length scale. These phases can be detected in ultracold gases of Rydberg atoms made from $^6$Li.

description: New observational facilities are probing astrophysical transients such as stellar explosions and gravitational wave (GW) sources at ever increasing redshifts, while also revealing new features in source property distributions. To interpret these observations, we need to compare them to predictions from stellar population models. Such models require the metallicity-dependent cosmic star formation history ($\mathcal{S}(Z,z)$) as an input. Large uncertainties remain in the shape and evolution of this function. In this work, we propose a simple analytical function for $\mathcal{S}(Z,z)$. Variations of this function can be easily interpreted, because the parameters link to its shape in an intuitive way. We fit our analytical function to the star-forming gas of the cosmological TNG100 simulation and find that it is able to capture the main behaviour well. As an example application, we investigate the effect of systematic variations in the $\mathcal{S}(Z,z)$ parameters on the predicted mass distribution of locally merging binary black holes (BBH). Our main findings are: I) the locations of features are remarkably robust against variations in the metallicity-dependent cosmic star formation history, and II) the low mass end is least affected by these variations. This is promising as it increases our chances to constrain the physics that governs the formation of these objects.
