description: We propose a quantum Fourier transform on photons in which a single atom-coupled cavity system mediates the photon-photon interactions. Our protocol utilizes time-delay feedback of photons and requires no active feedforward control. The time-delay feedback enables a single atom-cavity system to implement a quantum Fourier transform on an arbitrary number of photonic qubits on-the-fly, while rapid tuning of the atomic transition implements arbitrary controlled-phase gates. We analyze the performance of the protocol numerically and show that it can implement quantum Fourier transforms with tens of photons using state-of-the-art cavity quantum electrodynamics.

The effect of furosemide on sodium-22 uptake into cerebrospinal fluid and brain

description: Movement of sodium from plasma into the cerebrospinal fluid (CSF) in against an electrochemical gradient and this process is probably dependent upon active sodium transport.  CSF production is inhibited by chemical agents known to interfere with active transport of sodium in the kidney and other systems.  Since there are many similarities between renal tubule and choroid plexus epithelial cells, in was of interest to ascertain the effect of a potent saluretic agent on the uptake of radioactive sodium in the CSF and brain.  The effect of furosemide on the uptake of sodium-22 into the CSF and cerebral cortex of nephrectomized rats was studies.  Furosemide is a potent saluretic agent which abolishes the renal medullary sodium gradient and decreases the short-circuit current in the frog skin and toad bladder.  Furosemide, 1 mg/kg, was injected into the left lateral ventricle of the brain, sodium-22 was injected intraperitoneally and the uptake of the isotope into CSF, cerebral cortex, skeletal muscle, and brain was measured at intervals of 0.25 hour after the sodium-22 was administered.  During the initial 4 hour period after injection of the sodium-22, the uptake of the isotope was decreased in the furosemide-treated animals.  The maximum reduction in uptake occurred at the .0.25-hour time period.  The CSSF radioactivity in the treated animals, measured as sodium relative specific activity (RSA), was 37% less than that of the control animals.  At 24 hours, there was no difference to sodium-22 uptake in the CSF between the control and treated animals.  The uptake of sodium-22 into cerebral cortex was decreased in the treated animals.  The largest reduction in activity, 18%, occurred 2 hours after the injection of the isotope.  Since the brain extracellular space and the CSF appear to be in relatively free communication, this reduction could be the indirect result of the decreased uptake of sodium-22 into the CSF.  Furosemide has slight carbonic anhydrase inhibiting activity but it is probably inadequate to explain fully the reduced uptake of radioactive sodium into the CSF.  It is suggested that the decrease in sodium-22 uptake into CSF and brain in the furosemide-treated animals may be caused by inhibition of active sodium transport in the choroid plexus.

Alleviating the Hubble-constant tension and the growth tension via a transition of absolute magnitude favored by the Pantheon+ sample

description: We establish a cosmological-model-independent method to extract the apparent magnitude and its derivative at different redshifts from the Pantheon+ type Ia supernova sample, and find that the obtained values deviate clearly from the prediction of the $Λ$CDM model at the lowest redshift. This deviation can be explained as a result of a transition of the absolute magnitude $M$ in the low redshift region. The observations seem to favor this transition since the minimum values of $χ^2$ for two ansatzes of a varying $M$ are less than that of a constant $M$. The Hubble constant tension is alleviated from larger than $5σ$ to be about $1$ to $2σ$ for a varying $M$, and the growth tension can be resolved after attributing the variation of $M$ to a modification of the effective Newton's constant.

Analysis of antibody responses to streptococcal and tissue antigens in patients with acute rheumatic fever
Creators: name: Martins, Thomas Bernd
Publisher: name: University of Utah
Year: 2012
Subjects: Antigen-Antibody Reactions

description: Acute Rheumatic Fever (ARF) is an autoimmune disease occurring in individuals following untreated group A streptococcal infection believed to be triggered by antibodies to bacterial components that cross-react with human tissues.  A multiplexed immunoassay was developed for the simultaneous quantitation of antibodies to nine different streptococcal related antigens including streptolysin O (SLO), DNase B, Collagens I and IV, fibronectin, myosin, group A carbohydrate, M6 protein, and C5 peptidase. Development of the assay involved testing of several different types of microspheres as well serum diluent formulations in an effort to reduce nonspecific binding of antibodies.   Optimal coupling conditions for both protein and carbohydrate antigens to the microspheres were also determined. Monoclonal antibodies were used to determine antigen coupling efficiencies and cross-reactive epitopes of the different antigens. The multiplexed assay was then used to quantitate antibody responses in 49 ARF, 58 pharyngitis patients, and age and sex matched controls in samples collected at initial disease onset, and at 4 weeks, 6 months, and 1 year after diagnosis.  Through the selection of microspheres and serum diluent, nonspecific antibody binding was reduced by 17%. Different formulations of the coupling buffer were found to greatly influence the efficiency of coupling antigens to the carboxylated microspheres. Monoclonal antibodies against the different antigens demonstrated assay specificity as well as sensitivities of less than 1 ng/ml of antibody. Antibody responses were significantly higher for SLO, DNase B, M6 protein, group A carbohydrate, and the cross-reactive antigens collagen I and myosin in ARF compared to pharyngitis patients (p<0.05). Moreover, we found significantly elevated antibody responses in the ARF patients with rheumatic heart disease (RHD) to fibronectin and collagen I, compared to ARF patients without heart disease. The major differences between the ARF patients with and without carditis appear to be in the immune response to the putative heart valve components, collagen I and fibronectin.

Digital audio recording

description: Stockham: The Father of Digital Audio Recording is a mid-length documentary film that celebrates the life and achievements of former University of Utah professor Thomas Greenway Stockham, Jr. Despite Dr. Stockham's many accomplishments, his story remains relatively unknown outside of the audio engineering world, even at the University of Utah and in Salt Lake City, where much of his pioneering work was done. Various articles exist which document Stockham's achievements, but they do not capture his personality, his exceptional teaching abilities, or his perseverance to change the way we listen to music in the face of controversy. This film seeks to fill these gaps and to bring well-deserved attention to Dr. Stockham's story. Using Michel Chion's concept of "audio-vision" as a theoretical basis, I set out to create a film that would interest and engage audio aficionados as well as the general public. I researched my subject as thoroughly as possible by searching online, poring through library archives, and pre-interviewing Stockham's family, friends, and coworkers. I sought and successfully raised limited funds for travel, crew, equipment, and other expenses. I then traveled to Moab, Lake Powell, and Seattle to conduct roughly a dozen video interviews with many of the people I had pre-interviewed. I collected and digitized a wealth of archival photos, videos, and audio examples of Stockham's sound experiments. Finally, I edited together a rough cut of the film. A final cut was not achieved, however, I was offered a summer internship with KUED and a partnership with the Utah Film Center that will provide the time and resources necessary to polish the film for wider distribution. It is my hope that Stockham: The Father of Digital Audio iii Recording will be distributed in the film festival circuit or on public television, but ultimately, the film will be made publically available online for use as an educational and historical resource. It will help to preserve and disseminate a heretofore untold story of great relevance to the history of modern audio recording, Salt Lake City, and the University of Utah.
Paleoecological and isotropic records of climate change and variability from lakes and speleothems, Bear River Range, Southeastern Idaho

description: A paleoenvironmental reconstruction is presented from the Bear River Range, southeast Idaho. Reconstructed environmental conditions are inferred from paleoecological proxies, including pollen, macrofossils, and macroscopic charcoal from lacustrine sediments taken from Plan B Pond. A second, complementary paleoenvironmental reconstruction is presented based on stable carbon and oxygen isotope measurements of speleothem calcite collected from Minnetonka Cave, located just 8 km from Plan B Pond. The paleoenvironmental reconstructions from the two Bear River Range records suggest that each record contains significant seasonal bias, with the speleothem and sedimentary charcoal records primarily recording winter-season variability over time, and the pollen and macrofossil data recording summer conditions. Together, the Bear River Range data show a comprehensive picture of Holocene hydroclimatic conditions, and refines our understanding of controls on water resource variability in the region. Based on the Bear River Range records, the study area experienced cool, wet winters, and hot, dry summers in the early Holocene (prior to ~7500 BP), as compared to modern. The middle Holocene (7500-4000 BP) was characterized by dry and consistently warming winters, with dry, warm summers. The Late Holocene (4500 BP-Modern) has been characterized by cooler summers, with generally wetter, but increasingly variable, winter conditions. The results of this study indicate that previously published paleoclimate reconstructions from the Western United States must be considered carefully when using them to understand large-scale ocean atmosphere teleconnection patterns such as El-Nino Southern Oscillation (ENSO) and Pacific Decadal Oscillation (PDO). Because these teleconnection patterns are associated with spatially consistent seasonal precipitation and temperature anomalies, paleoclimate records must be evaluated for seasonal bias, if they are to be used for reconstructing past strength or presence of the teleconnection anomalies.

description: Photonics integrated circuitry would benefit considerably from the ability to arbitrarily control waveguide cross-sections with high precision and low loss, in order to provide more degrees of freedom in manipulating propagating light. Here, we report a new method for femtosecond laser writing of optical-fibre-compatible glass waveguides, namely spherical phase induced multi-core waveguide (SPIM-WG), which addresses this challenging task with three dimensional on-chip light control. Fabricating in the heating regime with high scanning speed, precise deformation of cross-sections is still achievable along the waveguide, with shapes and sizes finely controllable of high resolution in both horizontal and vertical transversal directions. We observed that these waveguides have high refractive index contrast of 0.017, low propagation loss of 0.14 dB/cm, and very low coupling loss of 0.19 dB coupled from a single mode fibre. SPIM-WG devices were easily fabricated that were able to perform on-chip beam rotation through varying angles, or manipulate polarization state of propagating light for target wavelengths. We also demonstrated SPIM-WG mode converters that provide arbitrary adiabatic mode conversion with high efficiency between symmetric and asymmetric non-uniform modes; examples include circular, elliptical modes and asymmetric modes from ppKTP (periodically-poled potassium titanyl phosphate) waveguides which are generally applied in frequency conversion and quantum light sources. Created inside optical glass, these waveguides and devices have the capability to operate across ultra-broad bands from visible to infrared wavelengths. The compatibility with optical fibre also paves the way toward packaged photonic integrated circuitry, which usually needs input and output fibre connections.

Flow around a solitary tree in a large field under neutral atmospheric stratification
Creators: name: Horne, Wyatt J.
Publisher: name: University of Utah
Year: 2012

description: A large-eddy simulation study was conducted to characterize the bulk momentum and turbulence features of flow around an isolated deciduous tree in the atmospheric boundary layer under neutral stratification. In addition to characterizing the flow field, a simplified model that contained the essential features of flow around an isolated tree was constructed. The flow structure around the tree consisted of a region of high velocity defect and high turbulent kinetic energy behind the tree with accelerated flow around the edges. The region of high velocity defect was found to form near the location of maximum leaf area density of the tree and to then spread and dissipate downstream approximately following a power law. The region of heightened turbulent kinetic energy was found to be dominated by the streamwise velocity variance. The turbulent stresses around the tree were found to have peaks near the edges of the tree with similar structure to axisymmetric and plane wakes. The similarities between the tree wake flow and canonical axisymmetric wakes was used to motivate a simplified empirical model. To agree with the LES data, the empirical model had two important differences to a standard axisymmetric wake model. First, the plume spread was found to be nonsymmetric between the vertical and horizontal directions and therefore, an angular plume dependence was introduced. Second, the isolated tree wake was found to dissipate within a shorter downstream distance than a standard axisymmetric wake model. To address this second difference, the empirical model breaks the wake up into two regions: a near wake region where plume statistics evolve linearly with downstream distance and a far wake region that exhibits power-law behavior. The model was found to accurately reproduce the turbulent stresses, turbulent kinetic energy, and mean velocity for deciduous trees. When tested for sensitivity to the location of maximum leaf area density, the model was found to overpredict the turbulent kinetic energy and streamwise velocity defect at lower locations.

description: We estimate the magnetic moment of electron neutrinos by computing the neutrino chirality flip rate that can occur in the core of a strange quark matter neutron star at birth. We show that this process allows neutrinos to anisotropically escape, thus inducing the star kick velocity. Although the flip from left- to right-handed neutrinos is assumed to happen in equilibrium, the no-go theorem does not apply because right-handed neutrinos do not interact with matter and the reverse process does not happen, producing the loss of detailed balance. For simplicity, we model the star core as consisting of strange quark matter. We find that even when the energy released in right-handed neutrinos is a small fraction of the total energy released in left-handed neutrinos, the process describes kick velocities for natal conditions, which are consistent with the observed ones and span the correct range of radii, temperatures and chemical potentials for typical magnetic field intensities. The neutrino magnetic moment is estimated to be $μ_ν\sim 3.6 \times 10^{-18}μ_B$, where $μ_B$ is the Bohr magneton. This value is more stringent than the bound found for massive neutrinos in a minimal extension of the \mbox{standard model.}

Ocular-motor methods for detecting deception: direct versus indirect interrogation

description: The present mock crime study investigated whether the accuracy of an ocular-motor deception test (ODT) that directly asks if the person committed illicit acts differs from the accuracy of an ODT that indirectly asks if the person provided false answers on a questionnaire about those illicit activities. Guilt, statement type, relevant issue, and completion of a pre-ODT questionnaire were manipulated in the present study to assess their effects on ocular-motor and behavioral measures of deception. Half the subjects were guilty of taking $20 from a secretary's wallet, and the other half were innocent. All subjects were told that some subjects took an exam from a professor's office, but in actuality, no one committed that crime. Three-fourths of the subjects completed a pre-ODT questionnaire that asked about their involvement in the crimes. Subjects answered 48 true/false items five times while their eye movements and pupil diameters were recorded. Half of the guilty and innocent subjects answered test items that directly asked if they committed the thefts. The remaining subjects were asked if they falsified information about the crimes on the pre-ODT questionnaire. Guilty subjects showed the largest pupil diameter while reading the cash items. For direct items, a discriminant function of four ocular-motor measures correctly classified 95% of innocent subjects and 83% of guilty subjects. For indirect items, the discriminant analysis of three ocular-motor measures correctly classified 79% of innocent subjects and 58% of guilty subjects. Results suggest that indirect test items are less effective than direct ones.

description: A study of the spin 1 Unruh-De Witt detectors interacting with a relativistic scalar quantum field is presented. After tracing out the field modes, the resulting density matrix for a bipartite qutrit system is employed to investigate the violation of the Bell-CHSH inequality. Unlike the case of spin $1/2$, for which the effects of the quantum field result in a decreasing of the size of violation, in the case of spin $1$ both decreasing and increasing of the violation may occur. This effect is ascribed to the fact that Tsirelson's bound is not saturated in the case of qutrits.

description: Internal gravity waves (IGWs) are likely to cause mixing in stellar interiors. Studies show that the mixing by these waves changes drastically across age and mass (Varghese et al. 2023, arXiv:2211.06432). Here, we study the effect of rotation on this wave mixing by considering a 7 M$_{\odot}$ model at ZAMS and midMS. We compare the mixing profiles at a range of rotation rates ($1\times 10^{-5}$, $2\times 10^{-5}$, $3\times 10^{-5}$, $4\times 10^{-5}$ and $1\times 10^{-4}$ rad.s$^{-1}$) and observe that the mixing decreases with decreasing Rossby number. This can be attributed to the effect of rotation on convection which influences the amplitude with which the waves are excited near the convective-radiative interface.

description: Quantum computing devices are inevitably subject to errors. To leverage quantum technologies for computational benefits in practical applications, quantum algorithms and protocols must be implemented reliably under noise and imperfections. Since noise and imperfections limit the size of quantum circuits that can be realized on a quantum device, developing quantum error mitigation techniques that do not require extra qubits and gates is of critical importance. In this work, we present a deep learning-based protocol for reducing readout errors on quantum hardware. Our technique is based on training an artificial neural network with the measurement results obtained from experiments with simple quantum circuits consisting of singe-qubit gates only. With the neural network and deep learning, non-linear noise can be corrected, which is not possible with the existing linear inversion methods. The advantage of our method against the existing methods is demonstrated through quantum readout error mitigation experiments performed on IBM five-qubit quantum devices.

Empowerment
Political behavior

description: Previous studies of minority political behavior have demonstrated that empowerment, as measured by the election of a minority person to public office, has positive effects on participation among the members of the minority community. Although the empowerment theory has yet to be applied to American Indians, it shows much promise in explaining participation rates among this minority group because of the theory's emphasis on political context; and attitudinal factors. This dissertation explored the role of empowerment on American Indian participation, first by comparing turnout prior to empowerment to turnout post empowerment in three counties in the West: San Juan County, Utah; Big Horn County, Montana; and Roosevelt County, Montana.  The findings indicate that turnout among Indians after empowerment, as defined by an Indian holding elected office, was higher than turnout prior to empowerment because of the positive effect of empowerment on perceptions and attitudes among American Indians. The election of an Indian to county office was a major context;ual change in each of the three counties, and the change had a positive impact on voter participation among Indians by influencing perceptions of government and attitudes of American Indians. Furthermore, the positive effect of empowerment on American Indian voters is both immediate and long-lasting. The positive effect on American Indian political behavior is evident immediately after empowerment, that is, Indians vote at higher rates in the first election following empowerment than prior to empowerment. Turnout continues to increase over time for American Indians, in contrast to non-Indian populations, indicating the long-lasting, positive effects of empowerment on Indian political behavior.

description: Films of metal-insulator nanogranular composites M$_x$D$_{100-x}$ with different compositions and atomic percentage of metal and dielectric phases (M = Fe, Co, Ni, CoFeB; D = Al$_2$O$_3$, SiO$_2$, ZrO$_2$; x $\approx$ 15-60 at.%) are investigated by electron magnetic resonance in a wide range of frequencies (f = 7-37 GHz) and temperatures (T = 4.2-360 K). At concentrations of the metallic ferromagnetic phase below the percolation threshold, the experimental spectra, besides the conventional ferromagnetic resonance signal, demonstrate an additional absorption peak characterized by a double effective g-factor g $\approx$ 4. The appearance of such a peak in the resonance spectra and its unusual properties are explained in the framework of the quantum mechanical "giant spin" model by the excitation of "forbidden" ("double quantum") transitions in magnetic nanogranules with a change of the spin projection $Δm = \pm2$.
Design of an exoskeletal human motion capture system (SenSuit™)

description: Human motion capture has a wide variety of applications in the entertainment and medical industries. Actors using motion capture devices provide realistic motion inputs for cartoons, virtual reality environments™, and computer and robot animation, resulting in tremendous time and cost savings. Medical applications include range of motion studies to diagnose injuries or identify insurance fraud, biomechanics studies of human performance and calculation of joint stresses, and ergonomics studies of humans in the workplace. There are common problems facing all methods of motion capture: how to attach the device to the individual's limbs, what sensors to use and how to use them, how to transmit data and convert it into a usable form, calibration of the device, data display, user comfort, and device reliability. Even when these problems are addressed, there are limitations in the kinematic model as well as human joint anomalies that make all methods imperfect. Currently, there are optical, magnetic, and exoskeletal devices for motion capture that vary widely in terms of performance, cost and limitations. Considering the likely environment and performance needs of the Sarcos Research Corporation, the SenSuit™ was built as an exoskeletal device. Creation of the SenSuit™ involved overcoming three major hurdles: the soft tissue interface, accurate joint angle measurement, and sensor design. The soft tissue interface is the series of rigid plates that are placed on skeletal landmarks located near the surface of the user's skin. Through appropriate location of the plates, a consistent, stable fit to the skeleton was achieved for users, which enhanced joint angle data. Accurate joint angle measurements were achieved either by aligning sensor rotation centers with approximate joint rotation centers or by computationally transforming the outputs of three degree of freedom sensor clusters located to reduce nonlinearities. A software routine allowed for quick, linear calibration of the individual. Joint angle sensors were designed that were small, linear, robust, and resistant to wear and contaminants. The SenSuit™ has proven itself both comfortable and reliable. It has been thoroughly tested in real-world applications, including real-time driving of graphical and robotic figures, as well as the programming of various robotic figures.

description: Aerodynamic losses and discharge coefficients are obtained for two different Pratt and Whitney axisymetric turbine airfoils with film cooling holes. Blade 3 results are given for the blowing ratios, of 0.42, 0.73, and 1.28. The pressure ratios are 1.18, 1.45, and 2.07 for the "ambient" tests and 1.12, 1.19, and 1.78 for the "cold" tests. The density ratios are 0.840, 0.88, and 0.973 for the "ambient" tests and 1.130, 1.37, and 1.330 for the "cold" tests. Blade 4 results are given for the blowing ratios, of 0.248, 0.39, and 0.697. The pressure ratios are 1.197, 1.357, and 1.876 for the "ambient" tests and 1.153, 1.305, and 1.607 for the "cold" tests. The density ratios are 0.838, 0.867, and 0.95 for the "ambient" tests and 1.032, 1.127, and 1.223 for the "cold" tests. Results of qualification tests of the Transonic Wind Tunnel are also given. These include test section inlet uniformity, flow variation with time, Schlerien images of the test section flow, and the Mach number distribution along the surface of the airfoil. All tests indicate satisfactory test section and wind tunnel preformance. The integrated aerodynamic losses for Blade 3 range between .0383 and 0.51 for the "ambient" tests and between 0.411 and 0.507 for the "cold" tests. For Blade 4, the integrated aerodynamic losses range from 0.525 and 0.55 for the "ambient" tests and 0.495 and 0.538 for the "cold" tests. Integrated aerodynamic losses are generally lower with "cold" injection than with "ambient" injection for Blade 3. Blade 3 gives lower integrated aerodynamic losses compared to blade 4 when compared at the same Mach number ratio. This is attributed to the different film hole geometries of the blades. The discharge coefficients associated with the film holes on Blade 3 range from 0.94 to 1.3 for "ambient" tests and 1.07 to 1.3 for ‘‘cold" tests. The discharge coefficients associated with the film holes on Blade 4 range from 0.54 to 0.78 for "ambient" tests and 0.55 to 0.80 for "cold" tests. Hole diameters used to calculate discharge coefficients are 0.381 mm and 0.469 mm for blades 3 and 4, respectively. These diameters account for some discharge coefficient values greater than one. In all cases, discharge coefficients increase as the pressure ratio increases, and discharge coefficients measured with freestream cross flow are generally lower than values measured with no freestream cross flow, for pressure ratios less than about 1.5, when compared at the same pressure ratio.
