description: We study in detail the threshold energy dependence of the seasonal variation effect in the energy integrated solar neutrino signal of the Super-Kamiokande detector in the case of the $ν_{e}\leftrightarrow ν_{μ,τ}$ vacuum oscillation (VO) solution of the solar neutrino problem. We show, in particular, that for the values of $Δm^2$ and $\sin^22θ$ from the VO solution region, the predicted time and threshold e^- energy ($T_{e,Th}$) dependence of the event rate factorize to a high degree of accuracy. As a consequence, the VO generated seasonal variation asymmetry is given by the product of an time-independent function of $T_{e,Th}$ and the standard geometrical asymmetry. For any given $Δm^2$ and $\sin^22θ$ from the VO solution region there exists at least one value of $T_{e,Th}$ from the interval (5 - 11) MeV, for which the seasonal variation effect in the solar neutrino sample of events, formed by recoil electrons with kinetic energy $T_{e} \geq T_{e,Th}$, is either maximal or very close to the maximal; it can vary dramatically with $T_{e,Th}$. Measuring the seasonal effect in each one of a large number of samples corresponding to different values of $T_{e,Th}$ from the indicated interval, say, to $T_{e,Th} = 5; 6; 7;...; 11 MeV$, provides a very effective test of the VO solution. Predictions for the magnitude of the seasonal effect in such samples are given for a large set of representative values of $Δm^2$ and $\sin^22θ$ from the VO solution region.

description: The stability of satellites in the solar system is affected by the so-called evection resonance. The moons of Saturn, in particular, exhibit a complex dynamical architecture in which co-orbital configurations occur, especially close to the planet where this resonance is present. We address the dynamics of the evection resonance, with particular focus on the Saturn system, and compare the known behavior of the resonance for a single moon to that of a pair of moons in co-orbital trojan configuration. We developed an analytic expansion of the averaged Hamiltonian of a trojan pair of bodies, including the perturbation from a distant massive body. {The analysis of the corresponding equilibrium points was restricted to the asymmetric apsidal corotation solution of the co-orbital dynamics.} We also performed numerical N-body simulations to construct dynamical maps of the stability of the evection resonance in the Saturn system, and to study the effects of this resonance under the migration of trojan moons caused by tidal dissipation. The structure of the phase space of the evection resonance for trojan satellites is similar to that of a single satellite, differing in that the libration centers are displaced from their standard positions by an angle that depends on the periastron difference $\varpi_2-\varpi_1$ and on the mass ratio $m_2/m_1$ of the trojan pair. The interaction with the inner evection resonance may have been relevant during the early evolution of the Saturn moons Tethys, Dione, and Rhea. In particular, Rhea may have had trojan companions in the past that were lost when it crossed the evection resonance, while Tethys and Dione may either have retained their trojans or have never crossed the evection. This may help to constrain the dynamical processes that led to the migration of these satellites and to the evection itself.

description: The directed percolation (DP) hypothesis for stochastic, range-4 cellular automata with acceptance rule $y \le\sum_{j=-4}^4 s_{i-j} \le 6$, in cases of $y < 6$ was investigated in one and two dimensions. Simulations, mean-field renormalization group and coherent anomaly calculations show that in one dimension the phase transitions for $y<4$ are continuous and belong to the DP class for $y=4,5$ they are discontinuous. The same rules in two dimensions for $y=1$ show $2+1$ dimensional DP universality; but in cases of $y > 1$ the transitions become first order.

description: In this article, we define two-particle system in Coulomb potential for twist-deformed space-time with spatial directions commuting to time-dependent function $f_{κ_a}({t})$. Particularly, we provide the proper Hamiltonian function and further, we rewrite it in terms of commutative variables. Besides, we demonstrate, that for small values of deformation parameters, the obtained in the perturbation framework, first-ordered corrections for ground Helium energy are equal to zero. In such a way we show, that nontrivial impact of space-time noncommutativity appears only at the second order of the quantum-mechanical correction expansion.

description: Twisted Bilayer graphene (TBG) is known to feature isolated and relatively flat bands near charge neutrality, when tuned to special magic angles. However, different criteria for the magic angle such as the vanishing of Dirac speed, minimal bandwidth or maximal band gap to higher bands typically give different results. Here we study a modified continuum model for TBG which has an infinite sequence of magic angles $θ$ at which, we simultaneously find that (i) the Dirac speed vanishes (ii) absolutely flat bands appear at neutrality and (iii) bandgaps to the excited bands are maximized. When parameterized in terms of $α\sim 1/θ, $ they recur with the simple periodicity of $Δα\simeq 3/2$, which, beyond the first magic angle, differs from earlier calculations. Further, in this model we prove that the vanishing of the Dirac velocity ensures the exact flatness of the band and show that the flat band wave functions are related to doubly-periodic functions composed of ratios of theta functions. Also, using perturbation theory up to $α^8$ we capture important features of the first magic angle $θ\approx1.09^{\circ}$ ($α\approx 0.586$), which precisely explains the numerical results. Finally, based on our model we discuss the prospects for observing the second magic angle in TBG.

description: This thesis consists of a collection of short stories and concepts that explore cultural and generational navigation—within families, friend groups, intimates and strangers. The cultural background of many of the characters is based on my own heritage: my mother’s family is from Cambodia, my father is from Peru, I was born on the Kentucky side of the Ohio River and would grow up in neighboring Cincinnati. I’m aware of how exotic this all sounds on paper; what I hope to do in this work is to interrogate that assumption, to render diversity in all its human facets and showcase characters that subvert and complicate the traditional immigrant narrative/experience. The stories that my parents, grandparents, and community members shared with me were always spoken—I heard their voices, watched their faces, sat at their sides. This collection is the first attempt at distilling those human interactions into fiction

description: Based on the self-consistent scheme beyond mean-field approximation in the large $N_c$ expansion, including current quark mass explicitly, a general scheme of SU(2) NJL model is developed. To ensure the quark self-energy expanded in the proper order of $N_c$, an approximate internal meson propagator is deduced, which is in order of $O(1/N_c)$. In our scheme, adopting the method of external momentum expansion, all the Feynman diagrams are calculated in a unified way by only expanding the quark propagator. Our numerical results show, that different from the mean field approximation in which the explicitly chiral symmetry breaking is invisible, the effect of finite pion mass can be seen clearly when beyond mean-field approximation.

description: In a previous paper J.-G. Luque and the author (Sem. Loth. Combin. 2011) developed the theory of nonsymmetric Macdonald polynomials taking values in an irreducible module of the Hecke algebra of the symmetric group $\mathcal{S}_{N}$. The polynomials are parametrized by $\left( q,t\right) $ and are simultaneous eigenfunctions of a commuting set of Cherednik operators, which were studied by Baker and Forrester (IMRN 1997). In the Dunkl-Luque paper there is a construction of a pairing between $\left( q^{-1},t^{-1}\right) $ polynomials and $\left( q,t\right) $ polynomials, and for which the Macdonald polynomials form a biorthogonal set. The present work is a sequel with the purpose of constructing a symmetric bilinear form for which the Macdonald polynomials form an orthogonal basis and to determine the region of $\left( q,t\right) $-values for which the form is positive-definite. Irreducible representations of the Hecke algebra are characterized by partitions of $N$. The positivity region depends only on the maximum hook-length of the Ferrers diagram of the partition.

description: Our paper will begin with an overview of the history of the drug trade in Afghanistan, and an assessment of why the illicit trade of opium is critical to US interests. We will then address the political and economic effects of the narco-trade on Afghanistan, which will identify possible impediments to successful implementation of counternarcotics plans. Next, we will discuss the Five Pillars Plan, which encompasses the five main policies of the US counternarcotics strategy in Afghanistan. Through an understanding of these issues and assessments, we will be able to analyze whether US policy strategies will be effective and whether US counternarcotics policies are addressing these issues.

description: A galvanic displacement reaction-based, room-temperature "dip-and-dry" technique is demonstrated for fabricating selectively solar-absorbing plasmonic nanostructure-coated foils (PNFs). The technique, which allows for facile tuning of the PNFs' spectral reflectance to suit different radiative and thermal environments, yields PNFs which exhibit excellent, wide-angle solar absorptance (0.96 at 15°, to 0.97 at 35°, to 0.79 at 80°) and low hemispherical thermal emittance (0.10) without the aid of antireflection coatings. The thermal emittance is on par with those of notable selective solar absorbers (SSAs) in the literature, while the wide-angle solar absorptance surpasses those of previously reported SSAs with comparable optical selectivities. In addition, the PNFs show promising mechanical and thermal stabilities at temperatures of up to 200°C. Along with the performance of the PNFs, the simplicity, inexpensiveness and environment-friendliness of the "dip-and-dry" technique makes it an appealing alternative to current methods for fabricating selective solar absorbers.

description: INTRODUCTION: Studies have shown that women living with a disability and women in conflict settings who are exposed to political violence are at higher risk for experiencing IPV, but more research is needed to examine IPV among women who have the combined vulnerability of living with a disability within a conflict setting. OBJECTIVE: This study examined the relationship between disability and perceptions of social norms regarding male-perpetrated intimate partner violence (IPV) against women in conflict-affected settings. METHODS: The study used secondary quantitative data drawn from a baseline study of 2018 violence prevention program in North Kivu, eastern Democratic Republic of Congo (DRC), by the International Rescue Committee (IRC). Perceptions of social norms were measured through the Partner Violence Norms Scale (PVNS) which measures perceptions of social norms surrounding gender norms and violence against women (VAW) in the home. A woman’s disability status was assessed based on severity as a three-level categorical variable. Linear regression models were applied to examine the relationship of a woman’s disability status and her PVNS score as well as her male partner’s PVNS score. RESULTS: Ninety-eight heterosexual couples were included. Women with severe disability had a lower PVNS scores on average than women with no disability (mean difference = -1.36, 95%CI: -2.39, -0.23, p = 0.014) when controlling for demographic variables. No significant difference in men’s PVNS scores based on their female partner’s disability status was found. CONCLUSION: These findings suggest that women with severe disability may perceive their communities to be less accepting of IPV than women with no disability, highlighting the complexity of the relationship between disability, IPV, and social norms and the importance of further analysis where disability as recognized as spectrum. Understanding social norms that influence IPV through PVNS scores may be used to inform understanding of male perpetration of abuse and how women perceive their own social roles and protections against IPV.
Searching for a stop-pair sample from top counting experiments at hadron colliders

description: The light stop pair if produced in hadron colliders and decaying through the likely decay chain stop->chargino + b followed by chargino->neutralino + f f', can mimic closely a top quark event when the mass of the stop is close to that of the top quark. Because of the much lower production rate, the stop event can be buried under the top quark event sample. In order to uncover the stop event, specific selection cuts need to be applied. Through Monte Carlo simulation with suitable kinematic cuts, we found that such stop event can be extracted from the top quark sample and detected by the top quark counting experiments in the upcoming upgraded Tevatron and LHC. However, because of the small statistics of the Run 1 of the Tevatron, the stop signal remains hidden at Run 1.

description: Human posture recognition provides a dynamic field that has produced many methods. Using fuzzy subsets based data fusion methods to aggregate the results given by different types of recognition processes is a convenient way to improve recognition methods. Nevertheless, choosing a defuzzification method to imple-ment the decision is a crucial point of this approach. The goal of this paper is to present an approach where the choice of the defuzzification method is driven by the constraints of the final data user, which are expressed as limitations on indica-tors like confidence or accuracy. A practical experimentation illustrating this ap-proach is presented: from a depth camera sensor, human posture is interpreted and the defuzzification method is selected in accordance with the constraints of the final information consumer. The paper illustrates the interest of the approach in a context of postures based human robot communication.

title: Period-doubling cascades in one and two parameter maps
Creators: name: (:Unkn) Unknown
Publisher: name: George Mason University
Year: 2020

description: Period doubling cascades are one of the most prominent features of one-parameter families of maps, F : R x M → M, where M is a locally compact manifold without boundary, typically RN. The dissertation is divided into two parts. In the first part period doubling cascades in one parameter maps are considered. In the second part we consider the implications of period doubling cascades in maps with two parameters. Our first set of results builds on 60 years of history of period doubling cascades in one parameter families. It has been previously proved that under certain conditions on a family of maps, cascades persist even under large perturbations in one dimensional maps and in coupled quadratic maps. We extend this work to prove that the cascades persist if we couple N one dimensional maps which satisfy certain conditions with a coupling g. Then, we use this result to prove the existence of cascades for a coupled family of cubic maps and for a mixed family of quadratic and cubic maps. Based on an established method for enumerating the period of a cascade, we are able to enumerate the cascades for a series of concrete examples including degree five and degree six polynomial maps. In the second part, we concentrate on results for period doubling cascades in two parameter families of maps. Starting with the work of Milnor it has been observed that when a bifurcation diagram for a map with multiple extrema is drawn in the parameter space, it is seen to contain many shrimp-like structures. A shrimp in the two parameter space can be viewed as a counterpart of a stable periodic window in one parameter bifurcation diagram. Many different methods have been used to investigate the parameter space like isoperiodic diagrams, continuation methods and the Lyapunov graph method. We use information from the first part to conclude results for the previously discussed shrimps for the cubic map. We demonstrate that shrimps occur in degree five and degree six polynomial maps derived in the previous section. We show that the shrimps appear in the parameter space for the values of the parameters where stable periodic window appears in the bifurcation diagram. In the past shrimps have not been observed in the quadratic map. We also compare the bifurcation diagram and the Lyapunov graph of a population model with three parameters and show that typical shrimps do not exist in its parameter space. We conjecture that a typical unimodal map does not have shrimps with multiple legs.

description:
A sample cell and delivery system for rapid matrix isolation of gas mixtures at constant gas temperature was designed and evaluated. The rotational energy differences of 1,2-dichlorosthane and of its deuterium compound wars then determined to test this technique.

The rotational energy barriers calculated from Boltzman plots of ths gases at different temperatures were; 1.21 + 0.38 keel/mole, 1.33 + 0.70 Real/mole, and 1.12 + 0.45 kcal/mole for the CH2 wagging„ C-Cl stretching and CD2 wagging modes respectively. These values were in good agreement with previously published values.

These results allowed evaluation of this apparatus and experimental design and suggested areas for possible improvement. The results also showed the value of rapid matrix isolation in the determination of rotational energy barriers in small molecules such as 1,2-dichlorosthans.

description: The measurement of forward jet cross sections has been suggested as a promising probe of new small x parton dynamics and the question is whether the new HERA data provide an indication of this. In this paper the influence of resolved photon processes has been investigated and it has been studied to what extent the inclusion of such processes in addition to normal deep inelastic scattering leads to agreement with data. It is shown that two DGLAP evolution chains from the hard scattering process towards the proton and the photon respectively, are sufficient to describe effects observed in the HERA data, which have been attributed to BFKL dynamics.

description: Part I of this study presented a stochastic theory for the clustering of monodisperse, rapidly settling, low-Stokes-number particle pairs in homogeneous isotropic turbulence. The theory involved the development of closure approximations for the drift and diffusion fluxes in the probability density function (PDF) equation for pair relative positions. In this Part II paper, the theory is quantitatively analyzed by comparing its predictions of particle clustering with data from direct numerical simulations (DNS) of isotropic turbulence containing particles settling under gravity. DNS were performed at a Taylor micro-scale Reynolds number $Re_λ= 77.76$ for three Froude numbers $Fr = \infty,~ 0.052,~ 0.006$. The Froude number $Fr$ is defined as the ratio of the Kolmogorov scale of acceleration and the magnitude of gravitational acceleration. Thus, $Fr = \infty$ corresponds to zero gravity, and $Fr = 0.006$ to the highest magnitude of gravity among the three DNS cases. For each $Fr$, particles of six Stokes numbers in the range $ 0.01 \le St_η\le 0.2$ were tracked in the DNS, and particle clustering quantified both as a function of separation and the spherical polar angle. %Here $St_η$~is the ratio of %the particle viscous relaxation time to the Kolmogorov time scale. We compared the DNS and theory values for the power-law exponent $β$ characterizing the dependence of clustering on separation. Reasonable agreement is seen between the DNS $β$'s for the $Fr = 0.006$ case and the theoretical predictions obtained using the second drift closure (referred to as DF2). Further, in conformity with the DNS, theory shows that the clustering of $St_η\ll 1$ particles is only weakly anisotropic.

description: We present and discuss the results of a Monte-Carlo simulation of the phase transition in pure compact U(1) lattice gauge theory with Wilson action on a hypercubic lattice with periodic boundary conditions. The statistics are large enough to make a thorough analysis of the size dependence of the gap. In particular we find a non-zero latent heat in the infinite volume limit. We also find that the critical exponents $ν$ and $α$ are consistent with the hyperscaling relation but confirm that the critical behavior is different from a conventional first-order transition.

description: Including the recent preliminary results of BaBar and BELLE experiments, we update the currently allowed intervals for various CKM parameters: $\barρ$, $\barη$, $\sin2β$, $\sin2α$, $\sin^2γ$. We also update the SM prediction for the rates of the $K_L \to π^0 ν\barν$ and $K^+ \to π^+ ν\barν$ decays, their ratio $a_{πν\barν}$, as well as for certain observables related to $B$ Physics like the CP asymmetries $a_{ψK_S}$ in $B^0_d \to J/ψK_S$ and $a_{ψϕ}$ in $B^0_s \to J/ψϕ$ or the mass differences $Δm_q$ ($q=d,s$) in the $B^0_q-\bar B^0_q$ systems. We investigate the correlations between them. The strongest correlations are between i) $a_{πν\barν}$ and $a_{ψK_S}$, ii) $\BR(K^+ \to π^+ ν\barν)$ and $Δm_d/Δm_s$ and iii) $\BR(K_L \to π^0 ν\barν)$ and $a_{ψϕ}$. These correlations are likely to be violated in the presence of New Physics and therefore provide stringent tests of the Standard Model.

S_3 and the L=1 Baryons in the Quark Model and the Chiral Quark Model

Year: 1998
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The S_3 symmetry corresponding to permuting the positions of the quarks within a baryon allows us to study the 70-plet of L=1 baryons without an explicit choice for the spatial part of the quark wave functions: given a set of operators with definite transformation properties under the spin-flavor group SU(3) x SU(2) and under this S_3, the masses of the baryons can be expressed in terms of a small number of unknown parameters which are fit to the observed L=1 baryon mass spectrum. This approach is applied to study both the quark model and chiral constituent quark model. The latter theory leads to a set of mass perturbations which more satisfactorily fits the observed L=1 baryon mass spectrum (though we can say nothing, within our approach, about the physical reasonableness of the parameters in the fit). Predictions for the mixing angles and the unobserved baryon masses are given for both models as well as a discussion of specific baryons.

title: Flow Sensing Based Environmental Perception Of Autonomous Underwater Robots
Creators: name: (:Unkn) Unknown
Publisher: name: George Mason University
Year: 2021

description: This dissertation investigates the environmental perception of autonomous underwater robots. Autonomous underwater robots have received increasing attention among scientific and engineering societies for their superior performances and promising future in marine environments. A key challenge to marine autonomy is the sensing of the background flow environment, which is important for navigation and motion control of a robot. This dissertation proposes a dynamic mode decomposition (DMD)-based flow sensing method inspired by the fish's lateral line system. DMD describes the dynamic flow field using the combination of a series of DMD modes that represent the core features of a certain flow field. This new reduced-order flow model not only captures the dynamics of the flow field, but also decreases the calculation burden; thus providing a control-oriented way to model the flow field. This flow model is integrated with a Bayesian filter to develop a DMD-based dynamic flow sensing method, which is potentially applicable to many and various complicated dynamic flow fields for arbitrarily shaped underwater robots. The number and location of sensors will both affect the flow sensing performance, because different sensor numbers and different positions contain different volumes of flow field information. The effects of these two designs in the proposed flow sensing algorithm will be investigated. Due to the harsh and unknown aquatic environment, the question of how autonomous underwater robots should navigate and maneuver, especially in a flow patterns changing environment, is still largely open. This dissertation presents a systematic background flow sensing framework to estimate surrounding flow fields with changing flow patterns and without considering transient effects. The proposed method first utilizes distributed pressure measurements of robots to determine the flow pattern/model around robots based on fast Fourier transform (FFT) spectrum analysis and then uses recursive Bayesian estimation and dynamic mode decomposition (DMD)-based modeling to identify model parameters. This algorithm seeks to detect a flow change around robots in flow pattern changing environments, which will greatly expand the application scope of the existing flow sensing methods to real-world scenarios.

description: This thesis is a fictional collection of short stories entitled Hearts & Minds. These short stories are threaded together into a single thesis using a centralized theme revolving around military conflict. However, Hearts & Minds explores additional impacts that go well beyond military confrontation, delving into a wide range of sub-themes including Post-Traumatic Stress Syndrome (PTSD), depression, courage, challenges of civilian re-integration, as well as the impacts on family members left behind when soldiers deploy to war. It is my goal that after reading this thesis, those unfamiliar with military culture will have an enlightened perspective into the trials and tribulations of the American soldier.
Two-loop Compton and annihilation processes in thermal QCD

description: We calculate the Compton and annihilation production of a soft static lepton pair in a quark-gluon plasma in the two-loop approximation. We work in the context of the effective perturbative expansion based on the resummation of hard thermal loops. Double counting is avoided by subtracting appropriate counterterms. It is found that the two-loop diagrams give contributions of the same order as the one-loop diagram. Furthermore, these contributions are necessary to obtain agreement with the naive perturbative expansion in the limit of vanishing thermal masses.

description: We numerically analyze the statistical properties of complex system with conditions subjecting the matrix elements to a set of specific constraints besides symmetry, resulting in various structures in their matrix representation. Our results reveal an important trend: while the spectral statistics is strongly sensitive to the number of independent matrix elements, the eigenfunction statistics seems to be affected only by their relative strengths. This is contrary to previously held belief of one to one relation between the statistics of the eigenfunctions and eigenvalues (e.g. associating Poisson statistics to the localized eigenfunctions and Wigner-Dyson statistics to delocalized ones).

One-Dimensional t-J Model from a Variational Viewpoint

name: Ogata, Masao
Publisher: name: arXiv
Year: 1995
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: The one-dimensional (1D) $t$-$J$ model is investigated by using a Gutzwiller-Jastrow-type variation method and the exact diagonalization of small systems. Variational expectation values are estimated by the variational Monte Carlo method with sufficient accuracy. First, we represent the diagonalization results. Physical quantities like momentum distribution and some correlation functions show some behaviors which are not expected in repulsive models, as the value of $J/t$ increases. These properties as well as energy are well understood by introducing intersite correlation factors into wave functions. The phase transition to a separated phase in large-$J/t$ region can be described by an attractive Jastrow wave function in quantitative agreement with the exact results. On the other hand, for the supersymmetric case ($J/t=2$) the original Gutzwiller wave function becomes an extremely good trial function for all the range of electron density. Here a kind of \lq\lq free electron" state is realized, particularly in the low electron density. Next, the above wave functions are compared with the Tomonaga-Luttinger-liquid-type wave function proposed by Hellberg and Mele. It is found that the correlation factors in short distances control bulk quantities like energy and the magnitude of correlation functions, while the long-range part of correlataion factors determines the critical behavior of correlation functions. Lastly, using these functions, charge and spin susceptibilities and magnetization curve are estimated, which agree with the exact results. It is shown that the Mott transition in 1D $t$-$J$ model is quite different from the Brinkman-Rice transition.

description: Computing quark propagators in lattice QCD is equivalent to solving large, sparse linear systems with multiple right-hand sides. Block algorithms attempt to accelerate the convergence of iterative Krylov-subspace methods by solving the multiple systems simultaneously. This paper compares a block generalisation of the quasi-minimal residual method (QMR), Block Conjugate Gradient on the normal equation, Block Lanczos and ($γ_5$-symmetric) Block BiConjugate Gradient.
