Subjects: subject: Law
subject: FOS: Law

description: In nineteenth century Ireland the Law was an over-crowded profession. Many educated upper-middle class young men, qualified in the Law or in other professions, found that they must make their careers away from their native land. Somewhat surprisingly, the distant Australian Colonies became destinations of choice for Irish lawyers who sought to pursue their profession overseas and to embark on a new life. In Australia many of those Irish lawyers achieved professional success, and often personal fulfilment in other fields of endeavour. Their lives and careers impacted significantly upon their new homeland in its advance to nationhood.
Expressing Algorithms As Concise As Possible via Computability Logic

Year: 2013
Subjects: subject: Logic in Computer Science (cs.LO)
subject: FOS: Computer and information sciences

description: This paper proposes a new approach to defining and expressing algorithms: the notion of {\it task logical} algorithms. This notion allows the user to define an algorithm for a task $T$ as a set of agents who can collectively perform $T$. This notion considerably simplifies the algorithm development process and can be seen as an integration of the sequential pseudocode and logical algorithms. This observation requires some changes to algorithm development process. We propose a two-step approach: the first step is to define an algorithm for a task $T$ via a set of agents that can collectively perform $T$. The second step is to translate these agents into (higher-order) computability logic.

description: In order to avoid unnecessary applications of Miller-Rabin algorithm to the number in question, we resort to trial division by a few initial prime numbers, since such a division take less time. How far we should go with such a division is the that we are trying to answer in this paper?For the theory of the matter is fully resolved. However, that in practice we do not have much use. Therefore, we present a solution that is probably irrelevant to theorists, but it is very useful to people who have spent many nights to produce large (probably) prime numbers using its own software.

description: This paper proposes the design of quadruple-tank process due to the unique multivariable MIMO system under minimum and non-minimum scenario with respect to the valve ratio. This model is then implemented the distributed estimation algorithm with decentralized control. The inputs are set in divergent gains of pumps while the four-tank process is interconnected so that the stability properties are different, making the usage of decentralized control is reasonable. The number of outputs is designed the same as those of inputs which are also that of distributed Luenberger observer with the continuous linearized dynamical system. This distributed comprises local estimates only in certain output, meaning that it would lead to insufficiency so that the neighbouring links under some network topologies are required in the dynamical system. This concept fortunately works in two different characteristic stability of the tank process regarding estimating the states. This success leads to the further research of the more large-scale complex system.

description: The network reciprocity is an important dynamic rule fostering the emergence of cooperation among selfish individuals. This was reported firstly in the seminal work of Nowak and May, where individuals were arranged on the regular lattice network, and played the prisoner's dilemma game (PDG). In the standard PDG, one often assumes that the players have perfect rationality. However, in reality, we human are far from rational agents, as we often make mistakes, and behave irrationally. Accordingly, in this work, we introduce the element of noise into the measurement of fitness, which is determined by the parameter a controlling the degree of noise. The considered noise-induced mechanism remarkably promotes the behavior of cooperation, which may be conducive to interpret the emergence of cooperation within the population.

title: Mormon Women's Peepstones: Divination, Revelation, Gender and Power in Utah
Creators: name: Tullis, Millie
Publisher: name: Utah State University
Year: 2023

description: This thesis illustrates the widespread and dynamic nature of early Mormon women’s use of peepstones in Utah, stretching from Mormons’ arrival in Utah in the mid nineteenth century into the early twentieth century. While many scholars have looked at seer stones in the context of Joseph Smith’s life, seer stones and peepstones were used by men, women, and children, decades after Smith’s death. This thesis considers the material context of peepstones in Utah, how the objects connected to people and their placemaking, and how new materialism and early Mormon theology contextualize magical objects such as peepstones. In that context, the thesis closely examines the stories about the “Logan peepstone woman,” Elvine Petersen, who was locally well-known during her life for her ability to give advice and counsel using peepstones and coffee grounds. While many scholars in the twentieth century briefly noted the existence of the peepstone woman in Logan, no previous scholarship has identified her as Elvine Petersen or contextualized her biography with the body of local folklore about her peepstone activities. This thesis is reflexive in its attempt to study a woman who left no sources of her own behind, and whose life has only been framed by other voices, but who gathered enough attention to generate a robust body of local and family folklore. This thesis also considers Petersen’s peepstone use in the larger context of Mormonism in the twentieth century. While previous scholars marked that peepstones practices seem to have ended near the turn of the century, Petersen’s life expands and complicates this timeline. Lastly, this thesis examines the larger community contexts of Mormon women’s divination in Utah. Like Elvine Petersen in Logan, many other Mormon women across Utah practiced divination for their communities. Mormon men and women went to peepstone women and other diviners for a variety of reasons, but these reasons generally were connected to gendered concerns. This thesis considers how these diviner women functioned in their Mormon community contexts, arguing that divination and revelation are social, community-based practices.

description: The concerns to autonomous vehicles have been becoming more intriguing in coping with the more environmentally dynamics non-linear systems under some constraints and disturbances. These vehicles connect not only to the self-instruments yet to the neighborhoods components, making the diverse interconnected communications which should be handled locally to ease the computation and to fasten the decision. To deal with those interconnected networks, the distributed estimation to reach the untouched states, pursuing sensorless design, is approached, initiated by the construction of the modified pseudo measurement which, due to approximation, led to the weighted average consensus calculation within unscented filtering along with the bounded estimation errors. Moreover, the tested vehicles are also associated to certain robust control scenarios subject to noise and disturbance with some stability analysis to ensure the usage of the proposed estimation algorithm. The numerical instances are presented along with the performances of the control and estimation method. The results affirms the effectiveness of the method with limited error deviation compared to the other centralized and distributed filtering. Beyond these, the further research would be the directed sensorless design and fault-tolerant learning control subject to faults to negate the failures.

description: We consider warm inflation in the context of holographic cosmology. The weak and the strong dissipative regime are analysed in the slow-roll approximation and within what is known as intermediate inflation. For an appropriate choice of the equation of state, the intermediate inflation is not only an exact solution in general relativity, but also in the holographic setup considered in this paper. Within this approach several dissipative and physically relevant functions are considered. We constrain our model using the latest Planck data. We conclude that three of the models analysed are consistent with Planck data for some ranges of the model parameters. However, one of them is ruled out by the observations.

description: We study the semi-holographic idea in context of decaying dark components. The energy flow between dark energy and the compensating dark matter is thermodynamically generalized to involve a particle number variable dark component with non-zero chemical potential. It's found that, unlike the original semi-holographic model, no cosmological constant is needed for a dynamical evolution of the universe. A transient phantom phase appears while a non-trivial dark energy-dark matter scaling solution keeps at late time, which evades the big-rip and helps to resolve the coincidence problem. For reasonable parameters, the deceleration parameter is well consistent with current observations. The original semi-holographic model is extended and it also suggests that the concordance model may be reconstructed from the semi-holographic idea.

title: Investigating the Effect of Greediness on the Coordinate Exchange Algorithm for Generating Optimal Experimental Designs
Creators: name: Gullion, William Thomas
Publisher: name: Utah State University
Year: 2023

description: Design of Experiments (DoE) is the field of statistics concerned with helping researchers maximize the amount of information they gain from their experiments. Recently, researchers have been turning to optimal experimental designs instead of classical/catalog experimental designs. One of the most popular algorithms used today to generate optimal designs is the Coordinate Exchange (CEXCH) Algorithm. CEXCH is known to be a greedy algorithm, which means it tends to favor immediate, locally best designs instead of globally optimal designs. Previous research demonstrated that this tradeoff was efficacious in that it reduced the cost of a single run of CEXCH and allowed more independent runs of the algorithm in a reasonable time. We devote part of this thesis to implementing and validating CEXCH in the Julia programming language. Different versions of CEXCH are examined, each with a different level of greediness. We implement a large computing study on 21 distinct design scenarios and two optimality criterion to benchmark the efficacy of CEXCH under different levels of greediness. We found that less greedy implementations of CEXCH generate optimal designs with greater probability at a moderate increase to cost.

description: Evaluation of blasting-induced rock damage and fragmentation is very important for safety control of construction in the jointed rock mass. The discontinuous numerical models are commonly applied due to the advantages in modeling fragmentation and treating discontinuities. In this paper, the rock fracturing algorithm and rate dependent strength law are incorporated into the discontinuous deformation analysis (DDA) to study the wave propagation and rock fragmentation phenomena in dynamic problems. By reproducing Hopkinson pressure bar tests under different loading rates, the improved method is validated to be capable of solving dynamic failure problem. Finally, taking the Xiucun tunnel as an example, its failure process under the action of the explosive wave is simulated, and some failure features are captured. In addition, the explosion wave propagation and its induced particle vibration in surrounding rock are studied. The reasonable simulation results indicate that the modified DDA method can effectively model the stress wave propagation and joint growth process in the jointed rock under blasting load. © 2021 Biting Xie et al.

description: We report high-precision measurements of the temperature and magnetic field dependence of the specific heat, C(T,H), across the magnetic phase diagram of MnSi. Clear anomalies establish the skyrmion lattice unambiguously as a thermodynamic phase. The evolution of the specific heat anomalies, the field dependence of the entropy released at the phase transitions, and the temperature versus field dependence of crossover lines provide striking evidence of a tricritical point at an internal magnetic field of 340mT and temperature of 28.5K. The existence of this tricritical point represents strong support of a helimagnetic Brazovskii transition, i.e., a fluctuation-induced first order transition at H = 0.

description: On 11 July 1897, a Swedish expedition under Salomon August Andrée attempted to reach the North Pole from Spitsbergen by balloon. The flight was terminated after only three days, as the weight of the balloon increased above a critical limit, due to an ice load caused by freezing fog and drizzle. Here the meteorological context of this expedition is discussed, in particular concerning the planning of the flight and in-flight weather conditions. Based on recently released pressure fields for the Arctic region for July 1897, obtained from the twentieth century reanalysis project (20CR), it can be shown that the Andrée expedition would not have reached the North Pole even with a perfect balloon, due to unfavourable wind conditions in the central Arctic after their departure from Spitsbergen.

description: We introduce and define a set of functions on pure bipartite states called entanglement moments. Usual entanglement measures tell you if two systems are entangled, while entanglement moments tell you both if and how two systems are entangled. They are defined with respect to a measurement basis in one system (e.g., a measuring device), and output numbers describing how a system (e.g., a qubit) is entangled with that measurement basis. The moments utilize different distance measures on the Hilbert space of the measured system, and can be generalized to any N-dimensional Hilbert space. As an application, they can distinguish between projective and non-projective measurements. As a particular example, we take the Rabi model's eigenstates and calculate the entanglement moments as well as the full distribution of entanglement.

description: As drones become more popular and easier to use, air spaces are becoming more congested. Airports, hospitals, and similar structures require controlled, safe airspaces and drones are increasingly a threat. Locally controlled airspace requires efficient removal of airborne threats to continue sensitive operations. Many methods have been investigated for removing drones from contested airspace. Generally these methods involve ground-based signal disruption, physical contact, or drone interception of a single intruder. In this work we present a drone interception model with a low-cost, low-capability group of short-range drones intercepting an incoming drone.

Using videos publicly available online, we study the highly energized collective motion of attendees at heavy metal concerts. We find these extreme social gatherings generate similarly extreme behaviors: a disordered gas-like state called a mosh pit and an ordered vortex-like state called a circle pit. Both phenomena are reproduced in flocking simulations demonstrating that human collective behavior is consistent with the predictions of simplified models.

description: Artificial intelligence (AI) models are increasingly finding applications in the field of medicine. Concerns have been raised about the explainability of the decisions that are made by these AI models. In this article, we give a systematic analysis of explainable artificial intelligence (XAI), with a primary focus on models that are currently being used in the field of healthcare. The literature search is conducted following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) standards for relevant work published from 1 January 2012 to 02 February 2022. The review analyzes the prevailing trends in XAI and lays out the major directions in which research is headed. We investigate the why, how, and when of the uses of these XAI models and their implications. We present a comprehensive examination of XAI methodologies as well as an explanation of how a trustworthy AI can be derived from describing AI models for healthcare fields. The discussion of this work will contribute to the formalization of the XAI field.

description: Global Navigation Satellite Systems (GNSS) are not only widely used for precise positioning, navigation and timing but also for establishing of terrestrial reference frames for geospatial applications, such as land and water management. The quality of GNSS carrier phase measurements depends on the knowledge about the location of the exact electrical reception point of the GNSS receiver antenna, also known as phase center. Because the location of this receiving point varies with the direction of the incoming satellite signal, phase center corrections (PCC), including a phase center offset (PCO) and phase center variations (PCV), have to be taken into account. These corrections are determined by a calibration of the antennas either in an anechoic chamber using artificially generated signals or in the field by use of a robot and real GNSS signals. The frequency dependent PCC are published in the IGS Antenna Exchange format (ANTEX). In order to take the benefits from the higher quality of the newer frequencies (like GPS L5) and satellite systems (e.g. Galileo or Beidou) so that multi-GNSS measurements can be processed, PCC have to be provided also for these signals. In this contribution, the calibration procedure developed at the Institut für Erdmessung (IfE) is presented. The robot model as well as the data acquisition and analysis is shown. Furthermore, the estimation process of the PCC using spherical harmonics is explained in details. We show, that an absolute GNSS receiver antenna calibration using a robot and real signals can successfully be carried out at the Institut für Erdmessung (IfE). The results underline an overall good repeatability with an RMS for the difference patterns of different calibrations smaller than two millimeters. It is shown that the L5 patterns significantly vary from L2, so that specific calibration values are needed. In addition, the concept of a joint estimation approach of same frequencies (like GPS L1 and Galileo L1) and its difference to the "classical" approach of frequency and system dependent pattern is presented. It can be seen, that differences up to 5.5 mm are present, if the joint estimated PCC are compared to the "classical" EL1X PCC. This underlines the demand of not only frequency but also GNSS specific PCC.

Experiments, conducted on the V(40nm)/Fe(1nm) S/F bilayer, have shown that experimental spin asymmetry measured at T = 0.5TC is shifted towards higher Q values compared to the curve measured at T = 1.5TC. Such a shift can be described by the appearance in superconducting vanadium of magnetic sub-layer with thickness of 7 nm and magnetization of +0.8 kG.

description: Scintrex Company Ltd. has built a very precise relative gravimeter AutoGrav CG-5 to explorer mineral, oil and GAS and to detect geotechnical events based on gravity measurements. All of these explorations are based on a glass-quartz spring, which are very sensitive to tilt, shake and temperature changes. Therefore, it is very essential to keep spring in a stable environment and avoiding of tilting and shaking it. In this investigation, the tilt behavior of glass-quartz spring of the CG-5 Scintrex relative gravimeter is tested. The main goal is to establish a relationship between duration of the tilt and offsets as function of time. Therefore, gravimeter is tilted by placing metal discs of different thickness and different times. The results show that CG5 gravimeter needs some hours to stabilize the glass quartz spring. The behavior of CG5 relative gravimeter and corresponding results will be presented.

description: Sb 2S 3 and Sb 2Se 3 are well-known layered bulk structures with weak van der Waals interactions. In this work we explore the atomic lattice, dynamical stability, electronic and optical properties of Sb 2S 3, Sb 2Se 3 and Sb 2Te 3 monolayers using the density functional theory simulations. Molecular dynamics and phonon dispersion results show the desirable thermal and dynamical stability of studied nanosheets. On the basis of HSE06 and PBE/GGA functionals, we show that all the considered novel monolayers are semiconductors. Using the HSE06 functional the electronic bandgap of Sb 2S 3, Sb 2Se 3 and Sb 2Te 3 monolayers are predicted to be 2.15, 1.35 and 1.37 eV, respectively. Optical simulations show that the first absorption coefficient peak for Sb 2S 3, Sb 2Se 3 and Sb 2Te 3 monolayers along in-plane polarization is suitable for the absorption of the visible and IR range of light. Interestingly, optically anisotropic character along planar directions can be desirable for polarization-sensitive photodetectors. Furthermore, we systematically investigate the electrical transport properties with combined first-principles and Boltzmann transport theory calculations. At optimal doping concentration, we found the considerable larger power factor values of 2.69, 4.91, and 5.45 for hole-doped Sb 2S 3, Sb 2Se 3, and Sb 2Te 3, respectively. This study highlights the bright prospect for the application of Sb 2S 3, Sb 2Se 3 and Sb 2Te 3 nanosheets in novel electronic, optical and energy conversion systems. © 2021, The Author(s).

title: Teachers' Conceptions and Enactment of Disciplinary Literacy in Elementary Science Instruction: A Comparative Case Study
Creators: name: Mendenhall, Melissa P.
Publisher: name: Utah State University

description: This case study explores elementary teachers’ conceptions and enactment of disciplinary literacy in elementary science instruction and the interaction between the two. Specifically, the purpose of this research was to describe how four fifth-grade teachers view literacy appropriate to science. Participants for this research were invited to participate by responding to an online survey and were selected based on criteria. Data sources include interviews, teacher artifacts, and observation. Qualitative data were coded, the codes compared to ideas in the field (overall themes), and global themes were generated as sense making tools to describe trends found in each case, case comparisons, and all cases together. The final written report includes narratives describing individual and comparison cases as well as the overall themes, global themes, and graphics displaying relationships between codes and themes for all cases. Findings suggest these educators’ view literacy as reading, writing, speaking and listening; text as written words; and science text as written words that contain science content. Additionally, teachers’ conceptions of disciplinary literacy were heavily focused on general literacy ideas of speaking, listening, reading, and writing to comprehend information. In practice, disciplinary literacy in science instruction again presented as general literacy acquisition. However, during enactment, each teacher’s unique conception of what is entailed in overall effective instruction interacted with general literacy ideas to personalize instruction. This suggests that teacher preparation programs and in-service teacher development opportunities should explicitly help educators to understand what disciplinary literacy is, how it is different from general literacy, what it looks like in instructional resources, and how to implement it during science instruction.

description: We present a microscopic theory of spin torque due to diffusive spin currents induced by spin accumulation. The obtained expression is a natural extension of the existing one due to 'local' spin currents associated with ordinary electric currents, and is the reciprocal of the spin motive force which induces charge accumulation as studied recently [J. Shibata and H. Kohno, Phys. Rev. B84, 184408 (2011)]. The result is applied to a domain wall motion in a nonlocal spin injection system, and the torque and force due to diffusive spin current are evaluated.

description: Large-scale faint structure detected by the recent observations in the halo of the Andromeda galaxy (M31) provides an attractive window to explore the structure of outer cold dark matter (CDM) halo in M31. Using an N-body simulation of the interaction between an accreting satellite galaxy and M31, we investigate the mass density profile of the CDM halo. We find the sufficient condition of the outer density profile of CDM halo in M31 to reproduce the Andromeda giant stream and the shells at the east and west sides of M31. The result indicates that the density profile of the outer dark matter halo of M31 is a steeper than the prediction of the theory of the structure formation based on the CDM model.

description: We use archival XMM-Newton observations of Ark 564 and Mrk 335 to calculate the frequency dependent time-lags for these two well-studied sources. We discover high-frequency Fe K lags in both sources, indicating that the red wing of the line precedes the rest frame energy by roughly 100 s and 150 s for Ark 564 and Mrk 335, respectively. Including these two new sources, Fe K reverberation lags have been observed in seven Seyfert galaxies. We examine the low-frequency lag-energy spectrum, which is smooth, and shows no feature of reverberation, as would be expected if the low-frequency lags were produced by distant reflection off circumnuclear material. The clear differences in the low and high frequency lag-energy spectra indicate that the lags are produced by two distinct physical processes. Finally, we find that the amplitude of the Fe K lag scales with black hole mass for these seven sources, consistent with a relativistic reflection model where the lag is the light travel delay associated with reflection of continuum photons off the inner disc.

Modelling solar irradiance variability on time scales from minutes to months

description: We analyze and model total solar irradiance variability on time scales from minutes to months, excluding variations due to p-mode oscillations, using a combination of convective and magnetic components. These include granulation, the magnetic network, faculae and sunspots. Analysis of VIRGO data shows that on periods of a day or longer solar variability depends on magnetic activity, but is nearly independent at shorter periods. We assume that only granulation affects the solar irradiance variability on time scales from minutes to hours. Granulation is described as a large sample of bright cells and dark lanes that evolve according to rules deduced from observations and radiation hydrodynamic simulations. Comparison of this model combined with a high time resolution magnetic-field based irradiance reconstruction, with solar data reveals a good correspondence except at periods of 10 to 30 hours. This suggests that the model is missing some power at these periods, which may be due to the absence of supergranulation or insufficient sensitivity of MDI magnetograms used for the reconstruction of the magnetic field-based irradiance reconstructions. Our model also shows that even for spatially unresolved data (such as those available for stars) the Fourier or wavelet transform of time series sampled at high cadence may allow properties of stellar granulation, in particular granule lifetimes to be determined.

description: Quantum-enhanced optical systems operating within the 2- to 2.5-μm spectral region have the potential to revolutionize emerging applications in communications, sensing, and metrology. However, to date, sources of entangled photons have been realized mainly in the near-infrared 700- to 1550-nm spectral window. Here, using custom-designed lithium niobate crystals for spontaneous parametric down-conversion and tailored superconducting nanowire single-photon detectors, we demonstrate two-photon interference and polarization-entangled photon pairs at 2090 nm. These results open the 2- to 2.5-μm mid-infrared window for the development of optical quantum technologies such as quantum key distribution in next-generation mid-infrared fiber communication systems and future Earth-to-satellite communications.

description: In order to find criteria for discrimination between surface color centers at terraces and steps, and bulk color centers, the characteristic losses of these centers have been investigated by electron energy loss spectroscopy on an epitaxial MgO film grown on a Ag (1,1,19) surface. This film contains a significantly higher step density compared with a film grown on Ag(100). The generation of four distinct losses at 2.0, 2.4, 2.8, and 3.4 eV and a broad loss centered at 5.5 eV have been observed that are induced by electron bombardment of the MgO surface. The latter loss is attributed to bulk color centers (Fb centers). By comparing the measured loss energies with experiments performed on MgO/Ag(100) and with theoretical literature data, the observed losses at 2.0 and 2.8 eV can be consistently assigned to transitions of color centers located on step sites, whereas those at 2.4 and 3.4 eV are attributed to terrace sites. The kinetics of color center formation during electron bombardment, as well as the annihilation of F centers by simple exposure to O2 gas at room temperature, was determined and compared for differently coordinated color centers. While all surface color centers follow the same kinetics, we show that the Fb centers can only decay as long as the existence of surface color centers provides active sites for dissociating oxygen molecules. This corroborates the assignment of Fb centers. © 2003 The American Physical Society

description: The third harmonic of a few-cycle pulse, generated at different dielectric surfaces, is investigated using interferometric frequency-resolved optical gating. We present direct experimental evidence for a non-instantaneous nonlinear response in a TiO2 thin film whereas surface third-harmonic generation in a SiO2 sample does not show any indication for non-instanteneity. To the best of our knowledge, this constitutes the first report of a non-instantaneous nonlinear optical response of a dielectric optical material.
