description: Recently, a large number of studies have been carried out on the early signatures of sudden regime shifts in systems as diverse as ecosystems, financial markets, population biology and complex diseases. Signatures of regime shifts in gene expression dynamics are less systematically investigated. In this paper, we consider sudden regime shifts in the gene expression dynamics described by a fold-bifurcation model involving bistability and hysteresis. We consider two alternative models, Models 1 and 2, of competence development in the bacterial population B. subtilis and determine some early signatures of the regime shifts between competence and noncompetence. We use both deterministic and stochastic formalisms for the purpose of our study. The early signatures studied include the critical slowing down as a transition point is approached, rising variance and the lag-1 autocorrelation function, skewness and a ratio of two mean first passage times. Some of the signatures could provide the experimental basis for distinguishing between bistability and excitability as the correct mechanism for the development of competence.

A study of the effect of repeated tension impact loads upon certain metals used in aircraft construction
Creators: name: Gentner, William Ellis

Publisher: name: California Institute of Technology
Year: 1940
Subjects: Aeronautics

description: The Impact Endurance Limit is evaluated for several materials used in aircraft construction. The Impact Endurance Limit is defined as the energy per blow in tension impact below which the specimen will withstand an indefinitely large number of blows without fracture.

The effect of grain orientation on the Impact Endurance Limit is shown.

Evidence is presented that the Impact Endurance Limit may be a function of the ultimate tensile strength but not of the elongation or the yield point.

The effect of service stresses on the Impact Endurance Limit is discussed.

description: We propose and analyze an approach for preparation of high fidelity entanglement and antiferromagnetic states using Rydberg mediated interactions with dissipation. Using asymmetric Rydberg interactions the two-atom Bell singlet is a dark state of the Rydberg pumping process. Master equation simulations demonstrate Bell singlet preparation fidelity $\mcF=0.998$. Antiferromagnetic states are generated on a four spin plaquette in agreement with results found from diagonalization of the transverse field Ising Hamiltonian.

description: NOTE: Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document.

A method is described for making estimates of the total emissivity of hydrogen in the temperature and pressure ranges where hydrogen atoms predominate under equilibrium conditions. For a characteristic geometrical depth of 50 cm, and temperatures of the order of 12,500[degrees]K and higher, with pressures of the order of 100 atmos and higher, the emissivity approaches unity [...] while for temperatures of the order of 9500[degrees]K and lower, with pressures of the order of 10 atmos and lower, the emissivity approaches zero [...]. The variations of the emissivity between these approximate limits are shown graphically as functions of temperature and pressure with the geometrical depth set at 50 cm. The variation of the emissivity with geometrical depth is also shown graphically at 12,600[degrees]K and 20 atmos.

description: Critical thermodynamics close to a metamagnetic quantum critical endpoint (QCEP) in a metal is discussed within the framework of spin-fluctuation theory. We analyze the effective potential for the Ising order parameter that is renormalized by spin-fluctuations and acquires a characteristic temperature dependence. The resulting magnetic field, H, and temperature, T, dependence of the magnetization, specific heat, thermal expansion, magnetostriction, susceptibility and the Grüneisen parameter are determined, and the crossover lines in the (H,T) phase diagram are specified. We point out that the metamagnetic QCEP is intrinsically unstable with respect to a magnetoelastic coupling.

description: We investigate the spin-dependent electron-phonon scatterings of the $L$ and $Γ$ valleys and the band structure near the conduction band minima in germanium. We first construct a $16\times16$ ${\bm k}\cdot{\bm p}$ Hamiltonian in the vicinity of the $L$ point in germanium, which ensures the correctness of the band structure of the lowest three conduction bands and highest two valence bands. This Hamiltonian facilitates the analysis of the spin-related properties of the conduction electrons. We then demonstrate the phonon-induced electron scatterings of the $L$ and $Γ$ valleys, i.e., the intra-$Γ$/ $L$ valley, inter--$Γ$-$L$ valley and inter--$L$-$L$ valley scatterings in germanium. The selection rules and complete scattering matrices for these scatterings are calculated, where the scattering matrices for the intra-$Γ$ valley scattering, inter--$Γ$-$L$ valley scattering and the optical-phonon and the separated transverse-acoustic- and longitudinal-acoustic-phonon contributions to the intra-$Γ$ valley scattering have not been reported in the literature. The coefficients in these scattering matrices are obtained via the pseudo-potential calculation, which also verifies our selection rules and wave-vector dependence. We further discuss the Elliott-Yafet mechanisms in these electron-phonon scatterings with the ${\bm k}$$\cdot$${\bm p}$ eigenstates at the $L$ and $Γ$ valleys. Our investigation of these electron-phonon scatterings are essential for the study of the optical orientation of spin and hot-electron relaxation in germanium.

description: Physical laws are believed to be invariant under the combined transformations of charge, parity and time reversal (CPT symmetry). This implies that an antimatter particle has exactly the same mass and absolute value of charge as its particle counterpart. Metastable antiprotonic helium ($\bar{p}{\rm He}^+$) is a three-body atom consisting of a normal helium nucleus, an electron in its ground state and an antiproton ($\bar{p}$) occupying a Rydberg state with high principal and angular momentum quantum numbers, respectively $n$ and $\ell$, such that $n\sim\ell\sim 38$. These atoms are amenable to precision laser spectroscopy, the results of which can in principle be used to determine the antiproton-to-electron mass ratio and to constrain the equality between the antiproton and proton charges and masses. Here we report two-photon spectroscopy of antiprotonic helium, in which $\bar{p}{\rm ^3He^+}$ and $\bar{p}{\rm ^4He^+}$ isotopes are irradiated by two counter-propagating laser beams. This excites nonlinear, two-photon transitions of the antiproton of the type $(n,\ell)\rightarrow (n-2,\ell-2)$ at deep-ultraviolet wavelengths ($λ$=139.8, 193.0 and 197.0nm), which partly cancel the Doppler broadening of the laser resonance caused by the thermal motion of the atoms. The resulting narrow spectral lines allowed us to measure three transition frequencies with fractional precisions of 2.3-5 parts in $10^9$. By comparing the results with three-body quantum electrodynamics calculations, we derived an antiproton-to-electron mass ratio of 1,836.1526736(23), where the parenthetical error represents one standard deviation. This agrees with the proton-to-electron value known to a similar precision.
Improved estimation of anomalous diffusion exponents in single particle tracking experiments

description: The Mean Square Displacement is a central tool in the analysis of Single Particle Tracking experiments, shedding light on various biophysical phenomena. Frequently, parameters are extracted by performing time-averages on single particle trajectories followed by ensemble averaging. This procedure however, suffers from two systematic errors when applied to particles that perform anomalous diffusion. The first is significant at short time lags and is induced by measurement errors. The second arises from the natural heterogeneity in biophysical systems. We show how to estimate and correct these two errors and improve the estimation of the anomalous parameters for the whole particle distribution. As a consequence we manage to characterize ensembles of heterogeneous particles even for rather short and noisy measurements where regular time averaged mean square displacement analysis fails. We apply this method to both simulations and in vivo measurements of telomere diffusion in 3T3 mouse embryonic fibroblast cells. The motion of telomeres is found to be subdiffusive with an average exponent constant in time. Individual telomere exponents are normally distributed around the average exponent. The proposed methodology has the potential to improve experimental accuracy while maintaining lower experimental costs and complexity.

title: Reimagining Culture With Youth: Relationship and Representation in Culturally Centered Learning Environments
Creators: name: Yan, Lili
Publisher: name: Utah State University
Year: 2023

description: This dissertation intends to develop an understanding of how culturally centered learning environments impact youth’s relationship with culture. Working alongside a multicultural team of researchers, educators, and designers who came together with a shared goal of designing curricular activities to engage sixth graders with culture, I followed 12 sixth graders for a school year to understand their development of relationships with culture. I (re)conceptualize the holistic process of learning and engagement with culture as Ti-Wu and propose a cultural learning model that helps us understand how youth develop multiple relationships with culture. I further share how multimedia technology mediates youth’s relationship with culture through remixing and reimagining. This dissertation has implications for the ways in which we can (1) design a culturally centered learning environment to engage youth with culture and support the development of diverse relationships with culture, (2) develop youth’s relationship with culture through designing multimedia learning activities in formal learning environments, and (3) decenter Western-oriented research discourse on cultural learning and development.

description: We introduce a new tool for the quantitative characterisation of the departure form Markovianity of a given dynamical process. Our tool can be applied to a generic $N$-level system and extended straightforwardly to Gaussian continuous-variable systems. It is linked to the change of the volume of physical states that are dynamically accessible to a system and provides qualitative expectations in agreement with some of the analogous tools proposed so far. We illustrate its prediticve power by tackling a few canonical examples.

description: Two models of rocket propelled projectiles have been tested in the Galcit 2 1/2 inch supersonic wind tunnel at a Mach Number of 3.06, and angles of attack from 0° to 10°. Variations of lift, drag, pitching moment, and position of center pressure with angle of attack have been obtained for each model.

A strain gage balance system, which was designed to measure the forces acting on the models was found to be entirely satisfactory for this purpose.

The results were found to agree very closely with the small perturbation theory for supersonic flow.

description: We find a new holographic description of strongly coupled defect field theories using probe D5 branes. We consider a system where a large number of probe branes, which are asymptotically D5 branes, blow up into a D7 brane suspended in the bulk of anti-de Sitter space. For a particular ratio of charge density to external magnetic field, so that the Landau level filling fraction per color is equal to one, the D7 brane exhibits an incompressible charge-gapped state with one unit of integer quantized Hall conductivity. The detailed configuration as well as ungapped, compressible configurations for a range of parameters near the gapped one are found by solving the D5 and D7 brane embedding equations numerically and the D7 is shown to be preferred over the D5 by comparing their energies. We then find integer quantum Hall states with higher filling fractions as a stack of D5 branes which blow up to multiple D7 branes where each D7 brane has filling fraction one. We find indications that the n D7 branes describing the filling fraction n state are coincident with a residual SU(n) symmetry when n is a divisor of the total number of D5 branes. We examine the issue of stability of the larger filling fraction Hall states. We argue that, in the D7 brane phase, chiral symmetry restoration could be a first order phase transition.

description: We study the electronic structure of chiral and achiral graphene nanoribbons with symmetric edges, including curvature and spin-orbit effects. Curved ribbons show spin-split bands, whereas flat ribbons present spin-degenerate bands. We show that this effect is due to the breaking of spatial inversion symmetry in curved graphene nanoribbons, while flat ribbons with symmetric edges possess an inversion center, regardless of their having chiral or achiral edges. We find an enhanced edge-edge coupling and a substantial gap in narrow chiral nanoribbons, which is not present in zigzag ribbons of similar width. We attribute these size effects to the mixing of the sublattices imposed by the edge geometry, yielding a distinct behavior of chiral ribbons from those with pure zigzag edges.

description: The purpose of this investigation was to investigate the stresses encountered for a semicircular expansion joint for a rocket motor. Information was desired to relate these stresses to the various parameters of the problem.

The stresses involved in this design were found to approximate those indicated by the exact membrane theory. The specimen having the lesser thickness was found to agree more closely with the exact membrane theory, and gave the lowest value of stresses.

An empirical method of membrane analysis, based on deformation profiles, was developed. This method is applicable for stresses slightly above the elastic limit and may be extrapolated for higher values.

The design tested was found to be inherently unsatisfactory on the basis of tests and theoretical considerations.

An alternative design was indicated which would have lower values of stress for a given value of deformation, and which could be designed strictly on the basis of theoretical calculations.

High quality polycrystalline samples were prepared using a solid state metathesis reaction. The unit cell increases upon Mn doping, but decreases again when additional F is inserted. The semiconducting character of LaFe1-xMnxAsO decreases with additional F doping. Muon spin relaxation (muSR) measurements reveal short range magnetic order in LaFe1-xMnxAsO and a suppression of magnetism by additional electron-doping with fluoride in LaFe0.9Mn0.1AsO1-yFy. Superconductivity remains absent even though the electronic preconditions are fulfilled in electron-doped LaFe0.9Mn0.1AsO1-yFy at x > 0.1, which is suggestive of effective pair breaking by Mn in this system.

Provenance information are essential for the traceability of scientific studies or experiments and thus crucial for ensuring the credibility and reproducibility of research findings. This paper discusses a comprehensive provenance framework combining the two types 1. workflow provenance, and 2. data provenance as well as their dimensions and granularity, which enables the answering of W7+1 provenance questions. We demonstrate the applicability by employing a biomedical research use case, that can be easily transferred into other scientific fields. An integration of these concepts into a unified framework enables credibility and reproducibility of the research findings.

An investigation of the effects of weight geometry and time in repeated tension impact testing

Year: 1944
Subjects: Aeronautics

description: The investigation covered in this report was conducted with the Falling-Carriage Repeated Tension Impact Machine at the Guggenheim Aeronautical Laboratory, California Institute of Technology, Pasadena, California.

Twenty-eight aluminum alloy test specimens were subjected to a total of 7,834 impacts in the GALCIT Falling-Carriage Repeated Tension -impact Machine. Since the average number of impacts per specimen was about 280 it is believed that this investigation covered a regime different from other investigations made with this equipment.

The effect of elapsed time between series of impacts was not established. The results obtained were contradictory, and it is believed that this was due to the energy per impact being variable and unknown.

It is established that the geometry of the weight used in this type of test has some influence upon the elongation produced.  It is shown that 17S-T duralumin is relatively sensitive to stress concentrations caused by change in cross-section and strain wave reflection, and relatively insensitive to stress concentrations due to small scribe marks.

Evidence is presented to indicate that the elongation at fracture of a specimen subjected to repeated tension impact is inversely proportional to the number of impacts required to produce fracture.

Suggestions are offered for improving the test equipment so as to obtain more nearly consistent results.

We are generating gauge configurations with four values of the lattice spacing ranging from 0.06 fm to 0.15 fm, and three values of the light quark mass, including the value for which the Goldstone pion mass is equal to the physical pion mass. We discuss simulation algorithms, scale setting, taste symmetry breaking, and the autocorrelations of various quantities. We also present results for the topological susceptibility which demonstrate the improvement of the HISQ configurations relative to those generated earlier with the asqtad improved staggered action.

description: We present a new perturbative formulation of non-equilibrium thermal field theory, based upon non-homogeneous free propagators and time-dependent vertices. The resulting time-dependent diagrammatic perturbation series are free of pinch singularities without the need for quasi-particle approximation or effective resummation of finite widths. After arriving at a physically meaningful definition of particle number densities, we derive master time evolution equations for statistical distribution functions, which are valid to all orders in perturbation theory and to all orders in a gradient expansion. For a scalar model, we perform a perturbative loopwise truncation of these evolution equations, whilst still capturing fast transient behaviour, which is found to be dominated by energy-violating processes, leading to the non-Markovian evolution of memory effects.

description: A physical description of the formation and propagation of the working surface inside the relativistic jet of the Blazar PKS 1510-089 are used to model its gamma-ray variability light curve using FERMI-LAT data from 2008 to 2012. The physical model is based on conservation laws of mass and momentum at the working surface as explained by Mendoza et al. (2009). The hydrodynamical description of the working surface is parametrised by the initial velocity and mass injection rate at the base of the jet. We show that periodic variations on the injected velocity profiles are able to account for the observed luminosity. With this, we are able to obtain mass ejection rates of the central engine which are injected at the base of the jet, and oscillation frequencies of the flow, amongst other physical parameters.

description: While many efforts have been made to make higher education in the US more equitable, there are still academic spaces in which some knowledges and some knowledge makers are marginalized. In this dissertation, I identify three such spaces: technical editing, graduate instructor training, and online academic research in trans communities. When editors make revisions based solely in American Standard English, as most editing practices and teaching are currently based, they risk marginalizing non-heritage speakers of English and speakers of various dialects of English, like African American Vernacular English. I suggest that by shifting our focus of editing from grammar policing to editing for underrepresented audiences, we can make editing a more inclusive space for marginalized voices. I give examples of how to create these kinds of interventions both in the editing classroom and through workshops for faculty. Next, I address how programs can better support graduate student instructors’ sense of wellbeing. I suggest that one of the best ways to develop inclusive interventions in graduate instructor training is by inviting graduate students to help design the ways in which departments communicate student wellbeing. Finally, to intervene into the anti-trans violence that continues to scour the United States, I propose an intervention into the ways that academics study online trans communities. Through these kinds of interventions, I demonstrate that we can continue the work of creating more inclusive spaces in higher education.

description: According to the no-hair theorem, astrophysical black holes are uniquely described by the Kerr metric. In order to test this theorem with observations in either the electromagnetic or gravitational-wave spectra, several Kerr-like spacetimes have been constructed which describe potential deviations from the Kerr spacetime in parametric form. For electromagnetic tests of the no-hair theorem, such metrics allow for the proper modeling of the accretion flows around candidate black holes and the radiation emitted from them. In many of these models, the location of the inner edge of the accretion disk is of special importance. This inner edge is often taken to coincide with the innermost stable circular orbit, which can serve as a direct probe of the spin and the deviation from the Kerr metric. In certain cases, however, an innermost stable circular orbit does not exist, and the inner edge of an accretion disk is instead determined by an instability against small perturbations in the direction vertical to the disk. In this paper, I analyze the properties of accretion disks in the Kerr-like metric proposed by Johannsen and Psaltis [Phys. Rev. D 83, 124015 (2011)], whose inner edges are located at the radii where this vertical instability occurs. I derive expressions of the energy and axial angular momentum of disk particles that move on circular equatorial orbits and calculate the locations of the inner disk edges. As a possible observable of such accretion disks, I simulate profiles of relativistically broadened iron lines and show that they depend significantly on the values of the spin and the deviation parameter.

description: We investigate electric quadrupole hyperfine structure constant ($B$) results in $^{135}$Ba$^+$ and $^{137}$Ba$^+$ and compare their ratios with the reported measurements of the ratio between the nuclear quadrupole moment ($Q$) values of these isotopes. We carry out confidence tests for the reported experimental $B$ values and calculations of $B/Q$ from the present work. Inconsistencies in the experimental $B$ values are observed in both the isotopes from different experiments performed using the same techniques. The present calculations are carried out using an all order relativistic many-body theory considering only single and double excitations in the coupled-cluster ansatz. After a detailed analysis of the results, the values of $Q$ we obtain for $^{135}$Ba and $^{137}$Ba are 0.153(2)$b$ and 0.236(3)$b$, respectively, which differ by about 4% from the currently referred precise values.

title: Daytime Versus Nighttime Sprinkler Irrigation of Two Urban Crops in a Semi-Arid Climate at High-Elevation
Creators: name: Pyakurel, Samikshya

description: Nighttime irrigation scheduling is a longstanding water conservation approach to reduce evaporative losses in Utah's semi-arid, urban landscapes. However, residential demand now exceeds system capacity, and the efficiency of the practice has come under question. Therefore, the objectives of this study include: 1) quantify whether a water savings exists between day and night irrigation with a water balance and energy balance approach, and 2) analyze microclimate and crop quality effects to determine any changes to evaporative demand or plant stress by irrigation timing. In 2019, we established 12 field plots in North Logan, UT (41.77° N, -111.81° W, 1380 m elevation) to test two irrigation timings (2:00 - 4:00 am and 2:00 - 4:00 pm) with two urban crops (turfgrass and zinnia cut flowers) on a sprinkler system in triplicate. Field instrumentation included a central weather station, flow meters on sprinkler sets, soil moisture sensors at 0.08 m and 0.18 m depths, canopy air temperature and vapor pressure, surface temperature, and catch cups for wind drift and canopy interception calculations. Daytime irrigation resulted in greater wind drift and evaporative losses (WDEL) by 7% compared to nighttime in both crops. A decrease in canopy and surface temperature, as well as the vapor pressure deficit was greater with daytime irrigation than nighttime, decreasing the evaporative demand at maximum air temperature (Tmax). Turf and zinnia yield and quality were not affected by irrigation timing, though the percentage cover of turf was significantly greater with daytime irrigation compared to nighttime. Thus, landscape irrigation scheduling should avoid hours with peak wind speed to reduce the WDEL and irrigate the field at or after Tmax to reduce the evaporative or heat stress to the crop.

description: We study a broad class of isotropic vacuum cosmologies in fourth-order gravity under the condition that the gravitational Lagrangian be scale-invariant or almost scale-invariant. The gravitational Lagrangians considered will be of the form L = f(R) + k(G) where R and G are the Ricci and Gauss-Bonnet scalars respectively. Specifically we take f(R) = R^2n and k(G) = G^n or k(G) = G ln G. We find solutions in closed form for a spatially flat Friedmann space-time and interpret their asymptotic early-time and late-time behaviour as well as their inflationary stages. One unique example which we discuss is the case of a very small negative value of the parameter b in the Lagrangian L = R^2 + b G ln G which leads to the replacement of the exact de Sitter solution from L = R^2 (being a local attractor) to a power-law inflation exact solution also representing a local attractor. This shows how one can modify the dynamics from de Sitter to power-law inflation by the addition of the G ln G-term.

description: We propose a quantum Monte Carlo (QMC) algorithm for non-equilibrium dynamics in a system with a parameter varying as a function of time. The method is based on successive applications of an evolving Hamiltonian to an initial state and delivers results for a whole range of the tuning parameter in a single run, allowing for access to both static and dynamic properties of the system. This approach reduces to the standard Schrödinger dynamics in imaginary time for quasi-adiabatic evolutions, i.e., including the leading non-adiabatic correction to the adiabatic limit. We here demonstrate this quasi-adiabatic QMC (QAQMC) method for linear ramps of the transverse-field Ising model across its quantum-critical point in one and two dimensions. The critical behavior can be described by generalized dynamic scaling. For the two-dimensional square-lattice system we use the method to obtain a high-precision estimate of the quantum-critical point $(h/J)_c=3.04463(12)$, where $h$ is the transverse magnetic field and $J$ the nearest-neighbor Ising coupling. The QAQMC method can also be used to extract the Berry curvature and the metric tensor.

description: An investigation was made into the advantages of using a discontinuous thrust program to escape from a cricular satellite orbit when using a low thrust propulsion unit. To make maximum use of the applied thrust, the perigee distance was chosen at a point where the atmospheric drag was negligible and this distance was held constant throughout the escape maneuver. A numerical integration was made of this method and the spiralling method. The appendixes show a comparison of these two methods.
