description: In the study of the brain, there is a hypothesis that sparse coding is realized in information representation of external stimuli, which is experimentally confirmed for visual stimulus recently. However, unlike the specific functional region in the brain, sparse coding in information processing in the whole brain has not been clarified sufficiently. In this study, we investigate the validity of sparse coding in the whole human brain by applying various matrix factorization methods to functional magnetic resonance imaging data of neural activities in the whole human brain. The result suggests sparse coding hypothesis in information representation in the whole human brain, because extracted features from sparse MF method, SparsePCA or MOD under high sparsity setting, or approximate sparse MF method, FastICA, can classify external visual stimuli more accurately than non-sparse MF method or sparse MF method under low sparsity setting.

description: We have investigated electrically-active magnetic excitations (electromagnons) in perovskite manganites with the $E$-type (up-up-down-down) spin structure by terahertz spectroscopy. Eu$_{1-x}$Y$_x$MnO$_3$ (0.1$\le x\le$1) and Y$_{1-y}$Lu$_y$MnO$_3$ (0$\le y\le$1) without magnetic $f$-moments, which host collinear sinusoidal, $A$-type, cycloidal, and $E$-type spin orders, are used to examine the systematics of possible electromagnons. Three-peak structures (23, 35, 45 cm$^{-1}$) of magnetic origin show up in the $E$-type phase with little composition ($y$) dependence of frequencies, making a contrast with the electromagnons observed in the cycloidal-spin ($x\le0.8$) phases. One of these electromagnon is ascribed to the zone-edge magnon mode based on the calculated magnon dispersions.

description: Metastatic dissemination of epithelial ovarian carcinoma occurs primarily through exfoliation of cells from the primary tumor,with subsequent implantation,invasion,and growth throughout the organs within the peritoneal cavity. Previous studies have suggested a role for matrix metalloproteinases (MMPs),particularly MMP-2,in ovarian cancer invasion and metastasis. To characterize further the role of MMPs and their inhibitors in ovarian carcinoma,in this study the production and activation of MMPs by short-term primary cultures of human ovarian epithelial carcinoma cells were analyzed. We report that MMP-2 is the predominant gelatinolytic MMP secreted by primary ovarian cancer cells derived from both ovarian tumors and ascites fluid. Furthermore,zymographic analysis demonstrated that MMP-2 is present in conditioned media in both the latent and activated forms,indicating that primary ovarian cancer cells catalyze proMMP-2 activation. Presence of a proMMP-2 activator was confirmed by immunohistochemistry and immunoprecipitation studies which found membrane-type 1 MMP (MT1-MMP) in the membranes of unstimulated cells and levels of both MT1-MMP and tissue inhibitor of metalloproteinases-2 (TIMP-2) were enhanced by culturing cells in the presence of concanavalin A. In addition,interaction of MMP-2 with the ovarian carcinoma cell surface resulted in a 2.5- to 5-fold increase in invasiveness. These data suggest that MT1-MMP-catalyzed activation of proMMP-2 may play a physiologic role in intraperitoneal invasion of ovarian carcinoma cells.

description: The Spectrometer and Telescope for Imaging X-rays (STIX) on board Solar Orbiter observes solar X-ray emission in the range of 4 – 150 keV and produces spectra and images of solar flares over a wide range of flare magnitudes. During nominal operation, STIX continuously generates data. A constant data flow requires fully automated data-processing pipelines to process and analyze the data, and a data platform to manage, visualize, and distribute the data products to the scientific community. The STIX Data Center has been built to fulfill these needs. In this paper, we outline its main components to help the community better understand the tools and data it provides. The STIX Data Center is operated at the University of Applied Sciences and Arts Northwestern Switzerland (FHNW) and consists of automated processing pipelines and a data platform. The pipelines process STIX telemetry data, perform common analysis tasks, and generate data products at different processing levels. They have been designed to operate fully automatically with minimal human intervention. The data platform provides web-based user interfaces and application programmable interfaces for searching and downloading STIX data products. The STIX Data Center has been operating successfully for more than two years. The platform facilitates instrument operations and provides vital support to STIX data users.

title: Waterfowl Production on a Spring-Fed Salt Marsh in Utah
Creators: name: McKnight, Donald E.
Publisher: name: Utah State University
Year: 1969

description: Results of past studies on the spring-fed salt marshes of Utah indicated that waterfowl production on these areas was much lower than on Utah's river-fed marshes. Waterfowl production on the newly-established Fish Springs National Wildlife Refuge, a spring-fed marsh, increased considerably, however, after its waters were impounded. It was believed that by determining what caused this increased production at Fish Springs it would be possible to obtain greater waterfowl production a t other spring-fed marshes. Consequently waterfowl populations and factors affecting waterfowl production on this marsh were studied during the summers of 1966, 1967, and 1968.
Populations of breeding ducks averaged approximately 900 pairs a year in 1967 and 1968. Mallards, cinnamon teal, and redheads comprised about 80 percent of these birds. Nesting densities, on plots representing available habitat, averaged about one nest per acre during these two years.
In 1967 and 1968 a total of 312 duck nests representing 10 species were studied and their fates determined. Overall nest success was 63 percent, and predators, principally coyotes and striped skunks, destroyed 25 percent of all nests.
Calculated duckling mortality rates during 1967 and 1968, respectively, were 19 and 16 percent. Duck production at Fish Springs averaged about 3,000 birds or about 430 ducks per square mile of marsh habitat a year during this period.
At present the sparsity of adequate nesting cover for gadwalls appears to be an important limitation to breeding by this species at Fish Springs. Nesting cover apparently has not limited the use of this marsh by other waterfowl species, however, as evidenced by a high incidence (76 percent) of nesting on dry ground by redheads and ruddy ducks.
Aquatic insect sampling in waters inundating portions of the original Fish Springs marsh indicated that these waters produced large quantities of proteinaceous foods for ducklings. Populations of aquatic insects in the original marsh were probably low except in recently disturbed areas.
It appears that limitations of brood-rearing habitat were primarily responsible for low waterfowl production in the past. Newly-created impoundments, rich in animal food, were probably the key to the increase in waterfowl production on this marsh.

An evaluation of a municipal work-for-relief project
Creators: name: Lautard, Emile Edouard Joseph
Publisher: name: University of British Columbia
Year: 2011

description: A recurring demand in the field of public assistance is the request that recipients should be expected to work for their allowances. A project based on this principle was operated by a municipality in the Lower Fraser Valley during the winter of 1961-62. This study attempts to evaluate the results achieved. The historical background of work-for-relief has been reviewed -particularly the experience of the United States and Canada. It is usually found that attempts to meet unemployment with a policy of work-relief are soon abandoned because available funds are quickly exhausted and it is never possible to provide work for all who apply for it. Direct relief is resorted to because it is less costly. When large numbers of persons become dependent upon public assistance the belief persists that many do so because they are unwilling to work. Policies are subsequently advocated which urge that recipients should be put to work to earn their allowances. Experience during the depression of the thirties indicated that, in fact, people wanted nothing so much as a job. The project under study was based on the assumption that the persons assigned were "chronic recipients of social assistance". The project operated from November, 1961 to May, 1962. A study carried out in the following August, 1962 indicated that anumber had not returned to social assistance rolls by that date. The inference was made that their work-for-relief assignment had contributed to a lessening of dependency. This study suggests that the lessening of dependency had actually begun five months prior to the operation of the project and was probably due to improved economic conditions. It was suggested that the primary causes of dependency were poor physical and mental health as well as adverse employment conditions. The study emphasized the need for adequately trained professional personnel in administering public assistance.

description: Optical solitons are known to be classically stable objects which are robust to perturbations. In this work, we show that due to quantum mechanical effects, an optical soliton that is initially in a classical soliton coherent state will shed photons into the continuum and hence decay. The standard formulation of the quantized soliton uses the linearized version of the quantum nonlinear Schrodinger equation in the background of the classical soliton, and the quantized soliton remains stable in this approximation. We show that if higher-order interaction terms are taken into account, the soliton is no longer stable, and its photon number decreases quadratically as a function of the number of soliton cycles. We compute the power spectrum for the continuum radiation and find a narrow band that is localized about the initial soliton momentum with a cut-off that is inversely proportional to the initial soliton width.

Finiteness for the k-factor model and chirality varieties

description: This paper deals with two families of algebraic varieties arising from applications. First, the k-factor model in statistics, consisting of n-times-n covariance matrices of n observed Gaussian variables that are pairwise independent given k hidden Gaussian variables. Second, chirality varieties inspired by applications in chemistry. A point in such a chirality variety records chirality measurements of all k-subsets among an n-set of ligands. Both classes of varieties are given by a parameterisation, while for applications having polynomial equations would be desirable. For instance, such equations could be used to test whether a given point lies in the variety. We prove that in a precise sense, which is different for the two classes of varieties, these equations are finitely characterisable when k is fixed and n grows.

description: We continue studying long-ranged quantum correlations of surface charge densities on the interface between two media of distinct dielectric functions which are in thermal equilibrium with the radiated electromagnetic field. Two regimes are considered: the non-retarded one with the speed of light $c$ taken to be infinitely large and the retarded one with finite value of $c$. The analysis is based on results obtained by using fluctuational electrodynamics in [L. Šamaj and B. Jancovici, Phys. Rev. E {\bf 78}, 051119 (2008)]. Using an integration method in the complex plane and the general analytic properties of dielectric functions in the frequency upper half-plane, we derive explicit forms of prefactors to the long-range decay of the surface charge correlation functions for all possible media (conductor, dielectric, vacuum) configurations. The main result is that the time-dependent quantum prefactor in the retarded regime takes its static classical form, for any temperature.

Cohesion and competition : family structure in eleven Chinese households
Creators: name: Bronsdon, Madeline
Publisher: name: University of British Columbia
Year: 2011

description: The subject of this dissertation is the form of the Chinese family in eleven Vancouver households. Using a theoretical model of the "traditional" family, this research is concerned with the differentiation of roles in the domestic unit and hos this is affected by the political and economic needs of the household. It is a view of Chinese family life expressed by children, and is concerned with how "traditional" family structure persists in these Chinese homes. Participant-observation, interviews, and a questionnaire were used to gain these insights. The research lasted for several months and was extended to include supplemented data from almost fifty Chinese families. A control group of non-Chinese respondents also completed the questionnaire. Nonetheless the dissertation as a whole is dependent upon data from the eleven households. It is the high degree of loyalty, co-operation, and cohesion in these families which is perhaps their most salient feature. This is related to the organization of the family store which all possess, the persistence of "traditional" differentiation of roles, and the agreement on high values of achievement. It is also related to the elusive but undeniable cultural identity of these households -- one which continues to affect family structure. In many respects these households approximate the "traditional" model, but one of its salient characteristics is lacking. There is no continuity of economic roles for children in these families, and this is highly significant for sons in particular. While at present there is family stability, the future will inevitably bring alterations in family structure as children assume economic roles outside the family: this is a radical departure from the "traditional" Chinese family.

description: Serious Games (SGs) have experienced a tremendous outburst these last years. Video game companies have been producing fun, user-friendly SGs, but their educational value has yet to be proven. Meanwhile, cognition research scientist have been developing SGs in such a way as to guarantee an educational gain, but the fun and attractive characteristics featured often would not meet the public's expectations. The ideal SG must combine these two aspects while still being economically viable. In this article, we propose a production chain model to efficiently conceive and produce SGs that are certified for their educational gain and fun qualities. Each step of this chain will be described along with the human actors, the tools and the documents that intervene.

description: We discuss a method that allows to compute the thermodynamic Casimir force at a given temperature in lattice models by performing a single Monte Carlo simulation. It is analogous to the one used by de Forcrand and Noth and de Forcrand, Lucini and Vettorazzo in the study of 't Hooft loops and the interface tension in SU(N) lattice gauge models in four dimensions. We test the method at the example of thin films in the XY universality class. In particular we simulate the improved two-component phi^4 model on the simple cubic lattice. This allows us to compare with our previous study, where we have computed the Casimir force by numerically integrating energy densities over the inverse temperature.

description: The aim of this project was to use an existing naturalistic data set to document the prevalence and risk of commercial truck and bus drivers’ activities or actions that distract their attention away from the driving task. This naturalistic data set involved thousands of commercial motor vehicles (including trucks and buses) and provided a wealth of data, including driver behavior during safety-critical events. The data set was provided by DriveCam® a vendor of onboard safety monitoring systems (OBMS) aimed at reducing risky driving behaviors. The OBMS contains video recordings and data from kinematic sensors (e.g., vehicle speed) in order to study driver behavior in driving conditions in the presence of real world daily pressures. These video recordings and kinematic data are used by fleet safety managers to provide feedback on safe and at-risk driving behaviors. Note that the authors of this study did not receive any video recordings, but rather kinematic data and driver behavior data that did not identify the driver.

We use Faraday rotation spectroscopy to make a continuous and minimally destructive measurement of the dynamics over multiple spin oscillations on a single evolving condensate. This method provides a sharp signature to locate a magnetically tuned separatrix in phase space which depends on the net magnetization. We also observe a phase transition from a two- to a three-component condensate at a low but finite temperature using a Stern-Gerlach imaging technique. This transition should be preserved as a zero-temperature quantum phase transition.

description: Gaussian boson sampling (GBS) is not only a feasible protocol for demonstrating quantum computational advantage, but also mathematically associated with certain graph-related and quantum chemistry problems. In particular, it is proposed that the generated samples from the GBS could be harnessed to enhance the classical stochastic algorithms in searching some graph features. Here, we use Jiuzhang, a noisy intermediate-scale quantum computer, to solve graph problems. The samples are generated from a 144-mode fully-connected photonic processor, with photon-click up to 80 in the quantum computational advantage regime. We investigate the open question of whether the GBS enhancement over the classical stochastic algorithms persists -- and how it scales -- with an increasing system size on noisy quantum devices in the computationally interesting regime. We experimentally observe the presence of GBS enhancement with large photon-click number and a robustness of the enhancement under certain noise. Our work is a step toward testing real-world problems using the existing noisy intermediate-scale quantum computers, and hopes to stimulate the development of more efficient classical and quantum-inspired algorithms.

Creators: name: Mahmoudi, Kooros M.
Publisher: name: Utah State University
Year: 1969

description: In a historical frame of reference, this is a study of rural-urban migration to demonstrate the process of urbanization in Utah between 1900 and 1960.
This study estimates the amount of internal migration for the state of Utah. Selected demographic variables such as size, age, and sex of the migrating population are studied. Changes in the population composition of the sending and receiving areas as a complement of rural-urban migration constitute the crux of this study.
The indirect methods of estimating the net intercensal migration, census survival and life table survival ratio met hods, are used in tabulations. Limitations were imposed, as for availability of the data , in usage of any direct methods of migration measurement. The survival ratio met hods used, however, are the most reliable in this context.
The results, indicating the intercensal amount of internal migration for Utah, shed some light on the urbanization process of the state. The findings, for the first time, demonstrate the volume and direction of the internal migration for Utah during the first six decades of the twentieth century. The results may substantially contribute to the state's future socio-economic plannings. Beyond a purely demographic analysis of the significance of migration lies the broad realm of manpower economics, institutional plannings, city plannings, rural problems, transportation, pollution, and a score of others. The population factor, naturally, cannot be separated from these social phenomena. The trends and directions of migration can, therefore, be used when and where future plans are formulated and past trends are studied.
title: The Effect of Cattle, Sheep, and Other Factors on Aspen (Populus tremuloides) Reproduction After Clear-Cut Logging in Southern Utah
Creators: name: Lucas, Paul A.
Publisher: name: Utah State University

description: Aspen is the most widespread deciduous tree of the western United States and the aspen type is important for water, forage, and wood products. Aspen reproduction on cutover areas was thought to be hindered by browsing and other factors, therefore a study was conducted to determine the effects of livestock, pocket gophers, disease, and snowpack damage on aspen reproduction during the first three years after clear-cutting. An enclosure was constructed and divided into nine paddocks. Controlled grazing by cattle and sheep was applied to six different paddocks during three summer periods. Three paddocks were protected from grazing. Results show that sheep utilized more sprouts than cattle, but controlled grazing by sheep or cattle did not prevent adequate aspen regeneration on good sites. Pocket gophers and disease appeared to be the most important decimating factors under controlled grazing. Sheep tended to concentrate on cutover areas so proper herding is needed to prevent misuse, especially the first and second years after initial sprouting.

description: By means of the Density Matrix Renormalization Group technique, we have studied the region where $XXZ$-like behavior is most likely to emerge within the phase diagram of the F-AF anisotropic extended ($J-J'$) Heisenberg chain. We have analyzed, in great detail, the equal-time two-spin correlation functions, both in- and out-of- plane, as functions of the distance (and momentum). Then, we have extracted, through an accurate fitting procedure, the exponents of the asymptotic power-law decay of the spatial correlations. We have used the exact solution of $XXZ$ model ($J'=0$) to benchmark our results, which clearly show the expected agreement. A critical value of $J'$ has been found where the relevant power-law decay exponent is independent of the in-plane nearest-neighbor coupling.

description: The problem of ordering operators has afflicted quantum mechanics since its foundation. Several orderings have been devised, but a systematic procedure to move from one ordering to another is still missing. The importance of establishing relations among different orderings is demonstrated by Wick's theorem (which relates time ordering to normal ordering), which played a crucial role in the development of quantum field theory. We prove the General Ordering Theorem (GOT), which establishes a relation among any pair of orderings, that act on operators satisfying generic (i.e. operatorial) commutation relations. We expose the working principles of the GOT by simple examples, and we demonstrate its potential by recovering two famous algebraic theorems as special instances: the Magnus expansion and the Baker-Campbell-Hausdorff formula. Remarkably, the GOT establishes a formal relation between these two theorems, and it provides compact expressions for them, unlike the notoriously complicated ones currently known.

The role of superfluidity in nuclear incompressibilities

Year: 2009
Subjects: subject: Nuclear Theory (nucl-th)

description: Nuclei are propitious tools to investigate the role of the superfluidity in the compressibility of a Fermionic system. The centroid of the Giant Monopole Resonance (GMR) in Tin isotopes is predicted using a constrained Hartree-Fock Bogoliubov approach, ensuring a full self-consistent treatment. Superfluidity is found to favour the compressibitily of nuclei. Pairing correlations explain why doubly magic nuclei such as $^{208}$Pb are stiffer compared to open-shell nuclei. Fully self-consistent predictions of the GMR on an isotopic chain should be the way to microscopically extract both the incompressibility and the density dependence of a given energy functional. The macroscopic extraction of K$_{sym}$, the asymmetry incompressibility, is questioned. Investigations of the GMR in unstable nuclei are called for. Pairing gap dependence of the nuclear matter incompressibility should also be investigated.

description: In this paper, we present a large-scale dynamical survey of the trans-Neptunian region, with particular attention to mean-motion resonances (MMRs). We study a set of 4121 trans-Neptunian objects (TNOs), a sample far larger than in previous works. We perform direct long-term numerical integrations that enable us to examine the overall dynamics of the individual TNOs as well as to identify all MMRs. For the latter purpose, we apply the own-developed FAIR method that allows the semi-automatic identification of even very high-order MMRs. Apart from searching for the more frequent eccentricity-type resonances that previous studies concentrated on, we set our method to allow the identification of inclination-type MMRs, too. Furthermore, we distinguish between TNOs that are locked in the given MMR throughout the whole integration time span ($10^8$\,years) and those that are only temporarily captured in resonances. For a more detailed dynamical analysis of the trans-Neptunian space, we also construct dynamical maps using test particles. Observing the fine structure of the $ 34-80 $~AU region underlines the stabilizing role of the MMRs, with the regular regions coinciding with the position of the real TNOs.

title: A Method for Plotting Isohyetal Maps Using an Analog Computer
Creators: name: Kirwan, Maurice George
Publisher: name: Utah State University
Year: 1969

description: The ability of the analog computer to stimulate physical phenomena is used in conjunction with a resistance paper model of the Walnut Gulch watershed in Arizona to plot constant precipitation maps from data obtained from recorded rainfall. Voltages which are proportional to rainfall at a specific raingage, located at scaled points of the resistance paper model, set up an electric field on the resistive sheet which is detected and processed by the computer. The detected potential is compared to a reference potential, or "precipitation value", and the necessary analog networks allow plotting of the equipotential line which is directly analogous to an isohyetal line.
title: Quantitative Evaluation of Saponin Content in Du Puits Alfalfa Foliage (Medicago sativa L.) with Trichoderma
Creators: name: Li-Chun, Wang
Publisher: name: Utah State University
Year: 1969

description: Selections in Du Puits alfalfa (Medicago sativa L. ) were evaluated for saponin content. The data obtained from the Trichoderma bioassay were converted to saponin values by regressions and standard curves. It was necessary to adjust the concentration of alfalfa extract in the bioassay so that the saponin content in alfalfa was estimated in that portion of the curve showing a marked response to saponin. A different regression was established for each group of low and high saponin plants of Du Puits alfalfa. The standard curve prepared with extract of Du Puits alfalfa used on the basis of its saponin content or the commercial purified saponin could be utilized for estimating the saponin content in Du Puits alfalfa, because the results were comparable to the values determined by chemical analysis. Attention should be given to the concentration of extract used when converting the bioassays to actual saponin content, because certain concentrations gave values more similar to the chemical analysis than others.
Two cycles of selection for low and high saponin content in Du Puits alfalfa were involved in the tests. The results indicated that the saponin content in low saponin plants was lower and that the saponin content in the high saponin plants was higher than in the unselected plants. They also showed that average saponin values in low and high saponin and the unselected plants were similar between the second and the third cuttings, but different from the first cutting
Oscillations of Echo Amplitude in Glasses in a Magnetic Field Induced by Nuclear Dipole-Dipole Interaction

description: The effect of a magnetic field on the dipole echo amplitude in glasses (at temperatures of about 10 mK) induced by the dipole-dipole interaction of nuclear spins has been theoretically studied. It has been shown that a change in the positions of nuclear spins as a result of tunneling and their interaction with the external magnetic field E_H lead to a nonmonotonic magnetic field dependence of the dipole echo amplitude. The approximation that the nuclear dipole-dipole interaction energy E_d is much smaller than the Zeeman energy E_H has been found to be valid in the experimentally important cases. It has been shown that the dipole echo amplitude in this approximation may be described by a simple universal analytic function independent of the microscopic structure of the two-level systems. An excellent agreement of the theory with the experimental data has been obtained without fitting parameters (except for the unknown echo amplitude)

title: A Forecast and Analysis of Educational Events Identified by Utah Educators
Creators: name: Handley, David Thatcher
Publisher: name: Utah State University
Year: 1969

description: Purpose
The purpose of this study was to determine how Utah educators and school board members view the future of education in the state. This was done by comparing the ratings for importance and the predictions on the time of occurrence of 53 educational events. An event was an incident or happening which might effect the education of the state . The hypotheses were based on the assumption that the various educational groups would hold differing views concerning the future of Utah education.
Procedure
The study provided data on the perceptions of 236 individual s representing five groups of educational participants (State Department personnel, superintendents, other administrators, teachers, and school board members) concerning the future of education in the State of Utah within a 20-year period of time. The sample was randomly selected, with the exception of the superintendent group which included all of the superintendents of the state. An instrument consisting of 53 educational events was developed which enabled the respondents to express their perceptions of the importance of the events and predict when each of the events would occur in 60 percent of the schools of the state. Leik's Measure of Ordinal Consensus was used to arrive at a consensus score which indicated the dispersion or lack of dispersion of responses within a group to a particular event. An analysis of variance was used to test for differences among the groups. where a significant F-ratio was found, using the .05 level of significance, Duncan's New Multiple Range Test was also utilized. This test was designed to locate differences between paired groups.

description: The development of multireference coupled cluster (MRCC) techniques has remained an open area of study in electronic structure theory for decades due to the inherent complexity of expressing a multi-configurational wavefunction in the fundamentally single-reference coupled cluster framework. The recently developed multireference coupled cluster Monte Carlo (mrCCMC) technique uses the formal simplicity of the Monte Carlo approach to Hilbert space quantum chemistry to avoid some of the complexities of conventional MRCC, but there is room for improvement in terms of accuracy and, particularly, computational cost. In this paper we explore the potential of incorporating ideas from conventional MRCC - namely the treatment of the strongly correlated space in a configuration interaction formalism - to the mrCCMC framework, leading to a series of methods with increasing relaxation of the reference space in the presence of external amplitudes. These techniques offer new balances of stability and cost against accuracy, as well as a means to better explore and better understand the structure of solutions to the mrCCMC equations.
