description: Recently, the market on deep learning including not only software but also hardware is developing rapidly. Big data is collected through IoT devices and the industry world will analyze them to improve their manufacturing process. Deep Learning has the hierarchical network architecture to represent the complicated features of input patterns. Although deep learning can show the high capability of classification, prediction, and so on, the implementation on GPU devices are required. We may meet the trade-off between the higher precision by deep learning and the higher cost with GPU devices. We can success the knowledge extraction from the trained deep learning with high classification capability. The knowledge that can realize faster inference of pre-trained deep network is extracted as IF-THEN rules from the network signal flow given input data. Some experiment results with benchmark tests for time series data sets showed the effectiveness of our proposed method related to the computational speed.

A fundamental question in evolutionary biology is understanding why some groups of organisms are highly diverse. Species diversity is the result of the balance between speciation and extinction whereas morphological disparity is primarily a consequence of adaptation. Radioresitance, among other adaptive features found in organisms, can be genetically determined and inherited. This study explores the possible consequences that naturally-occurring radiation might impose on the variance and composition of population genetics. To evaluate these possibilities, a simple statistical experiment is conducted involving 49 cytochrome gene sequences belonging to two distinct populations of eukaryotic organisms that reside on opposite ends of the radioresistance spectrum. The results show a distinct correlation between higher and lower degrees of genetic variance among these two groups, where the order, group or population that has shown increased hypersensitivity to radiation also has an increased rate of molecular evolution due to a higher mutation rate.
Multiplicities of pizero, eta, Kzero and of charged particles in quark and gluon jets

description: We compared the multiplicities of pizero, eta, Kzero and of charged particles in quark and gluon jets in 3-jet events, as measured by the OPAL experiment at LEP. The comparisons were performed for distributions unfolded to 100% pure quark and gluon jets, at an effective scale Qjet which took into account topological dependences of the 3-jet environment. The ratio of particle multiplicity in gluon jets to that in quark jets as a function of Qjet for pizero, eta and Kzero was found to be independent of the particle species. This is consistent with the QCD prediction that the observed enhancement in the mean particle rate in gluon jets with respect to quark jets should be independent of particle species. In contrast to some theoretical predictions and previous observations, we observed no evidence for an enhancement of eta meson production in gluon jets with respect to quark jets, beyond that observed for charged particles. We measured the ratio of the slope of the average charged particle multiplicity in gluon jets to that in quark jets, C, and we compared it to a next-to-next-to-next-to leading order calculation. Our result, C=2.27+-0.20(stat+syst),is about one standard deviation higher than the perturbative prediction.

description: Numerical simulation is carried out to study the phenomenon of vortex breakdown in an enclosed cylinder. The energy gradient theory is used to explain the vortex breakdown in the cylinder with consideration of centrifugal force, Coriolis force, angular momentum and azimuthal vorticity. The research results show that the large value of energy gradient function K is mainly located at the centerline and the region between the circulation vortices on both sides of the cylinder and the vortex breakdown bubbles at the centerline. It is found that the position of the local peak value of the energy gradient function K at the centerline corresponds to the location of vortex breakdown first occurrence. The position of the local peak value of K function in horizontal direction corresponds to the velocity inflection points except for the centerline. The vortex breakdown is mainly determined by the high K value at the centerline for low aspect ratio. The influence of the region of high K value between the circulation vortices on both sides of the cylinder and the vortex breakdown bubbles at the centerline becomes larger with the increase of the aspect ratio. The occurrence and development of the vortex breakdown bubble may be affected by the region of high K value between the circulation vortices on both sides of the cylinder and the vortex breakdown bubbles at the centerline for high aspect ratio.

description: We consider the effects of going beyond the approximation of a straight string in mesons by using a flexible flux tube model wherein a Nambu-Goto string bends in response to quark accelerations. The curved string is dynamically identical to the straight string even for ultra-relativistic mesons except for a small additional radial momentum. We numerically solve the curved string model in the case where both ends have equal mass quarks and also the case where one end is fixed. No approximation of non-relativistic motion is made. We note some small but interesting difference from the straight string.

Subjects: subject: Spatial indexing
subject: GIS

description: Spatial indexing is critical for retrieving data efficiently from geospatial databases, and has been a long-standing research direction of GIS. In a departure from recent spatial indexing paradigms, this study leverages pivot indexing. Pivot indexing begins by selecting a small number of points from the dataset. Then, the distances from the points in this subset- the pivots- to every point in the database are stored in secondary memory. During query time, these pre-computed values are used to evaluate candidates for range or nearest neighbor search. This approach offers a substantial reduction in the number of distance computations necessary to evaluate objects in the spatial plane. While previous spatial pivot indexing research leverages graphical processing units, this study utilizes an alternative parallelization mechanism- distributed computing. The Hadoop file system is used to accelerate index creation and querying in a scalable fashion. The results are then compared to an existing distributed solution. I ultimately discovered that my implementation of the pivot index at the distributed level underperformed existing methods by a small margin; however, my implementation offered an improved kNN query performance. These results affirm the legitimacy of the pivot indexing approach, and suggest that similar approaches deserve further investigation. Ultimately, this research does not assert that pivot indexing is superior to other approaches. Rather, it is an exploration of pivot indices in a specific computing context (the Hadoop File System). Thus, the contribution to the research community is in application. The outcome of this study is to demonstrate the utility of this particular indexing paradigm in the Hadoop software environment.

description: The renormalization-group (RG) approach proposed earlier by Shankar for interacting spinless fermions at $T=0$ is extended to the case of non-zero temperature and spin. We study a model with $SU(N)$-invariant short-range effective interaction and rotationally invariant Fermi surface in two and three dimensions. We show that the Landau interaction function of the Fermi liquid, constructed from the bare parameters of the low-energy effective action, is RG invariant. On the other hand, the physical forward scattering vertex is found as a stable fixed point of the RG flow. We demonstrate that in $d=2$ and 3, the RG approach to this model is equivalent to Landau's mean-field treatment of the Fermi liquid. We discuss subtleties associated with the symmetry properties of the scattering amplitude, the Landau function and the low-energy effective action. Applying the RG to response functions, we find the compressibility and the spin susceptibility as fixed points.

description: We present magneto-hydrodynamic simulations of liquid sodium flow with the PLUTO compressible MHD code. We investigate the influence of the remnant magnetic field orientation and intensity, impinging velocity field due to Ekman pumping as well as the impeller dimensions on the magnetic field collimation by helical flows in between the impeller blades. For a simplified cartesian geometry we model the flow dynamics of a multi-blades impeller inspired by the Von-Karman-Sodium (VKS) experiment. The study shows that a remnant magnetic field oriented in the toroidal direction is the less efficient configuration to collimate the magnetic field, although if the radial or vertical components are not negligible the collimation is significantly improved. If the intensity of the remnant magnetic field increases the system magnetic energy is larger but the magnetic field collimation efficiency is the same, so the gain of magnetic energy is smaller as the remnant magnetic field intensity increases. The magnetic field collimation is modified if the impinging velocity field changes: the collimation is weaker if the impinging velocity increases from Gamma=0.8 to 0.9, slightly larger if the impinging velocity decreases from Gamma=0.8 to 0.7. The analysis of the impeller dimensions points out that the most efficient configuration to collimate the magnetic field requires a ratio between impeller blade height and base longitude between 0.375 - 0.5. The largest enhancement of the hypothetical alpha^2 dynamo loop, compared to the hypothetical Omega-alpha dynamo loop, is observed for the model that mimics TM 73 impeller configuration rotating in the unscooping direction with a remnant magnetic field of 10^-3 T orientated in the radial or vertical direction. The optimization trends obtained in the parametric analysis are also confirmed in simulations with higher resolution and turbulence degree.

description: We study the question whether the phenomenologically successful VMD approach to weak radiative hyperon decays can be made consistent with Hara's theorem and still yield the pattern of asymmetries exhibited by experimental data. It appears that an essential ingredient which governs the pattern of asymmetries is the off-shell behaviour of the input electromagnetic 1/2^- 1/2^+ γcouplings. Although this behaviour can be chosen in such a way that the experimentally observed pattern is obtained, and yet Hara's theorem satisfied, at the same time the approach yields a definite prediction for the size of weak meson-nucleon coupling constants. Comparison with experiment reveals then another conflict.

description: Here we investigate the decay patterns of the low-lying hidden strangeness nucleon resonances ($\equiv N_{s\bar{s}}$) to the strangeness channels by employing the chiral Lagrangian approach, where the $N_{s\bar{s}}$ states are treated as compact pentaquark states. The $S$-wave decays of these states to the $PB$ (pseudoscalar meson and baryon) and $VB$ (vector meson and baryon) channels are studied. According to the obtained masses and decay properties, we find four states, namely, $N_{s\bar{s}}(1874)$ with quantum numbers $I(J^{P})=1/2(1/2^{-})$, $N_{s\bar{s}}(1885)$ with $I(J^{P})=1/2(3/2^{-})$, $N_{s\bar{s}}(2327)$ with $I(J^{P})=1/2(1/2^{-})$, and $N_{s\bar{s}}(2252)$ with $I(J^{P})=1/2(3/2^{-})$, may be associated to the well established nucleon resonances $N^*(1895)$, $N^{*}(1875)$, and the newly predicted $N^{*}(2355)$ and $N^{*}(2250)$ by CLAS collaboration, respectively. In addition, several other obtained hidden strangeness nucleon resonances may be expected to be dominant components of the predicted missing resonances in the literatures.

description: We propose a model for diffusion-limited annihilation of two species, $A+B\to A$ or $B$, where the motion of the particles is subject to a drift. For equal initial concentrations of the two species, the density follows a power-law decay for large times. However, the decay exponent varies continuously as a function of the probability of which particle, the hopping one or the target, survives in the reaction. These results suggest that diffusion-limited reactions subject to drift do not fall into a limited number of universality classes.

description: We present a multi-wavelength study of the FSRQ CTA 102 using Fermi-LAT and simultaneous Swift-XRT/UVOT observations. The Fermi-LAT telescope detected one of the brightest flares from this object during Sep, 2016 to Mar, 2017. In the 190 days of observation period the source underwent four major flares. A detailed analysis of the temporal and spectral properties of these flares indicates the flare at MJD 57751.594 has a $γ$-ray flux of (30.12$\pm$4.48)$\times 10^{-6}$ ph cm$^{-2}$ s$^{-1}$ (from 90 minutes binning) in the energy range of 0.1--300 GeV. This has been found to be the highest flux ever detected from CTA 102. Time dependent leptonic modelling of the pre-flare, rising state, flares and decaying state has been done. A single emission region of size $6.5\times 10^{16}$ cm has been used in our work to explain the multi-wavelength spectral energy distributions. During flares the luminosity in electrons increases nearly seventy times compared to the pre-flare state.

description: This thesis describes Iranian American diaspora organizations and their role in peace building and in acting as a bridge between their two historically conflicting countries. This thesis will look at the various diaspora communities and their engagement during a conflict that involves their homeland. Additionally, elements that define a diaspora organization’s ability to engage constructively in peace-building efforts will be presented. A case study of one of the largest and most active Iranian American diaspora organizations, National Iranian American Council (NIAC), will be conducted. NIAC’s aims and efforts will be analyzed in order to gain an understanding of the organizations strengths, potentials and limitations in peace-building between Iran and the United States. The continuously stalemated U.S.-Iran conflict is in dire need of a new approach. Thus, looking at other potential influencers, such as the diaspora, may be paramount in reaching peace between these two nations.

description: It was recently pointed out that the fundamental Planck mass could be close to the TeV scale with the observed weakness of gravity at long distances being due the existence of new sub-millimeter spatial dimensions. In this picture the standard model fields are localized to a $(3+1)$-dimensional wall or ``3-brane''. We show that in such theories there exist attractive models of inflation that occur while the size of the new dimensions are still small. We show that it is easy to produce the required number of efoldings, and further that the density perturbations $δρ/ρ$ as measured by COBE can be easily reproduced, both in overall magnitude and in their approximately scale-invariant spectrum. In the minimal approach, the inflaton field is just the moduli describing the size of the internal dimensions, the role of the inflationary potential being played by the stabilizing potential of the internal space. We show that under quite general conditions, the inflationary era is followed by an epoch of contraction of our world on the brane, while the internal dimensions slowly expand to their stabilization radius. We find a set of exact solutions which describe this behavior, generalizing the well-known Kasner solutions. During this phase, the production of bulk gravitons remains suppressed. The period of contraction is terminated by the blue-shifting of Hawking radiation left on our wall at the end of the inflationary de Sitter phase. The temperature to which this is reheated is consistent with the normalcy bounds. We give a precise definition of the radion moduli problem.

description: The quantum spin states of atomic ensemble are of special interesting for both fundamental studies and precision measurement applications. Here, we propose a scheme to prepare collective quantum states of an atomic ensemble placed in an optical cavity via homodyne measurement of probing light field. The effective interactions of atoms mediated by photons are enhanced by the optical cavity, and the output probe light could also be entangled with the collective spin states. By selectively measuring the quadrature of output light, we can prepare various quantum states, including superposition states of Dicke states and Dicke squeezed states. It is also demonstrated that the fidelity of prepared quantum state can be enhanced by repetitive homodyne detection and using longer probe laser pulses. Our scheme is feasible for experimental realization with current technologies, which may be used in future study of quantum mechanics and quantum metrology.

description: We consider the compressible isentropic Euler equations on $\mathbb{T}^d\times [0,T]$ with a pressure law $p\in C^{1,γ-1}$, where $1\le γ<2$. This includes all physically relevant cases, e.g.\ the monoatomic gas. We investigate under what conditions on its regularity a weak solution conserves the energy. Previous results have crucially assumed that $p\in C^2$ in the range of the density, however, for realistic pressure laws this means that we must exclude the vacuum case. Here we improve these results by giving a number of sufficient conditions for the conservation of energy, even for solutions that may exhibit vacuum: Firstly, by assuming the velocity to be a divergence-measure field; secondly, imposing extra integrability on $1/ρ$ near a vacuum; thirdly, assuming $ρ$ to be quasi-nearly subharmonic near a vacuum; and finally, by assuming that $u$ and $ρ$ are Hölder continuous. We then extend these results to show global energy conservation for the domain $Ω\times [0,T]$ where $Ω$ is bounded with a $C^2$ boundary. We show that we can extend these results to the compressible Navier-Stokes equations, even with degenerate viscosity.

description: Report is made of a systematic scaling study of the finite-temperature chiral phase transition of two-flavor QCD with the Kogut-Susskind quark action based on simulations on $L^3\times4$ ($L$=8, 12 and 16) lattices at the quark mass of $m_q=0.075, 0.0375, 0.02$ and 0.01. Our finite-size data show that a phase transition is absent for $m_q\geq 0.02$, and quite likely also at $m_q=0.01$. The scaling behavior of susceptibilities as a function of $m_q$ is consistent with a second-order transition at $m_q=0$. However, the exponents deviate from the O(2) or O(4) values theoretically expected.

title: The Influence of Information Quality and Gender on the Social Commerce Adoption Framework by Saudi Arabian Users Using the UTAUT2 Theory

description: Social media (SM) is used extensively in Saudi Arabia, especially by women for online shopping. The number of active social media users has ranked the country as one of the strongest business markets in the world, and the largest Information and Communication Technology (ICT) market in the Middle East. These numbers are set to trend upwards, particularly in the context of “Vision 2030”, an initiative announced in 2016 by Crown Prince Mohammed bin Salman. This comprehensive socio-political plan aims to provide equal job opportunities for both genders and increase Saudi Arabia’s economy through improving business markets. This study investigates the adoption of social commerce as one of the technologies under development by employing the Unified Theory of Acceptance and Use of Technology (UTAUT2) to test the influence of information quality and gender on a user’s intention to buy products from social media websites. The extensive use of SM raises questions about whether Saudi Arabian users are willing to adopt social commerce or not, and this study draws from an online survey conducted among 300 Saudi Arabian participants. This survey data was analyzed by using Structural Equation Modeling (SEM). The research results indicate that there is a positive relationship between information quality and behavioral intention for adopting social commerce, gender as a moderator has no statistically significant effect on the UTAUT2 constructs for adopting social commerce. The managerial implications of this study are explained. The key findings of this thesis are used to propose effective recommendations for improving business performance by adopting social commerce based on the Saudi Arabian user’s preferences.

title: Essays on the Economic History of the Philippines: from Unintended Benefits to the Spanish Empire to the Political Economy of Rice Policy
Creators: name: (:Unkn) Unknown
Publisher: name: George Mason University
Year: 2019

description: In this dissertation, I attempt to explore some of the issues in the economic history of the Philippines that remain relatively understudied by the literature. The first chapter explores the unintended benefits of the Philippines to the Spanish empire. The Philippines was viewed as a significant financial burden to Spain. The colony did not have the spices or gold that the Spanish conquistadors were hoping to find. And more importantly, through the Manila-Acapulco galleon trade, the colony diverted silver from flowing from the Americas towards Spain. I use data from 1500-1650 on silver production, silver importation, price levels in Spain, and counterfactual scenarios of the amount of silver flowing across the Pacific towards the Philippines to show that the Philippines provided an unintended benefit to the Empire by acting as an inflationary heat sink and preserving the purchasing power of the Crown’s revenue. The second paper documents and traces the origin of rice importation and protection policies that resulted from the economic transformation of the colony after the collapse of the Manila-Acapulco galleon trade. The weak and incomplete property rights during the Spanish period resulted in the rise of a landed elite that was able to monopolize elected positions during the American period. They were able to achieve this by taking advantage of their patronage relationships and so gaining the ability to influenced national food policy. The intertwining of both colonial legacies made it almost impossible to remove protectionist policies for rice. Given the rice policies and rice shortages faced by the Philippines during the first half of the 20th century, the third paper attempts to identify the main determinants in rice production using provincial-level data from three censuses (1903, 1918, and 1939). The results have important implications for minimizing food shortages in the country. That is, trade protection of the rice sector and policies aimed at improving the productivity of rice farmers may not be enough to promote self-sufficiency in rice that policymakers hope for.
Mixed-State Quasiparticle Spectrum for d-wave Superconductors

description: Controversy concerning the pairing symmetry of high-$T_c$ materials has motivated an interest in those measurable properties of superconductors for which qualitative differences exist between the s-wave and d-wave cases. We report on a comparison between the microscopic electronic properties of d-wave and s-wave superconductors in the mixed state. Our study is based on self-consistent numerical solutions of the mean-field Bogoliubov-de Gennes equations for phenomenological BCS models which have s-wave and d-wave condensates in the absence of a magnetic field. We discuss differences between the s-wave and the d-wave local density-of-states, both near and away from vortex cores. Experimental implications for both scanning-tunneling-microscopy measurements and specific heat measurements are discussed.

description: A QCD sum rule calculation of Balistky and Ji on the spin content of the nucleon is done with a different approach to the evaluation of the bilocal contributions and to the extraction of the nucleon pole residues. The result obtained is much more numerically stable which puts their conclusion that about half of the nucleon spin is carried by gluons on firmer ground.

description: Letter from William G. Andersen, Jr. and Debra J. Collins to George Kain, 2 October 1986. This letter serves as notice to George Kain that Reston was not among the cities chosen as a finalist in the All-America Cities program. The All-America Cities program recognizes citisen group iniative and action, not action taken solely by public officials, and the balance of civic, public, and private sector action is carefully weighed in the decision process. The letter is accompanied by a copy of the entrance form provided by Kain. Andersen and Collins address specific reasons why Reston was not chosen as the All-American City including waning civic involvement, previously noted problem areas had not significantly changed; and unconvincing descriptive language about Reston.
