description: Electron scattering on both neutral ($X$) and charged ($X^-$) excitons in quantum wells is studied theoretically. A microscopic model is presented, taking into account both elastic and dissociating scattering. The model is based on calculating the exciton-electron direct and exchange interaction matrix elements, from which we derive the exciton scattering rates. We find that for an electron density of $10^9 {\rm cm}^{-2}$ in a GaAs QW at $T=5K$, the $X^-$ linewidth due to electron scattering is roughly twice as large as that of the neutral exciton. This reflects both the $X^-$ larger interaction matrix elements compared with those of $X$, and their different dependence on the transferred momentum. Calculated reflection spectra can then be obtained by considering the three electronic excitations of the system, namely, the heavy-hole and light-hole 1S neutral excitons, and the heavy-hole 1S charged exciton, with the appropriate oscillator strengths.

description: This dissertation examines the role and influence of state, federal, and institutional policies in the experiences of developmental students and instructors enrolled in, or teaching at, community colleges. Through the theoretical framework of Pierre Bourdieu’s relational sociology and Field Theory, I organized and examined narratives and interviews from students and instructors at one community college. These narratives and interviews worked to articulate participants’ positions in related fields of power as they navigated the complexities of academic bureaucracies like financial aid, admissions, and enrollment. Particular attention was paid to the ways in which financial aid and college remediation interact. The data from both groups revealed that policy implementation has marked influence on classroom experience, even when—and perhaps because—instructors and students are unaware of the specific and particular policies themselves. The data revealed that both students and instructors make decisions based on faulty or flawed understandings of academic policies. Based on these understandings, I recommend policy literacy programs for both students and instructors and call for greater policy transparency so that students may navigate complex bureaucracies at community colleges and be better prepared to self-advocate for best practices.

description: We construct conformal three-point functions in momentum space with a general tensor and conserved currents of spin $1$ and $2$. While conformal correlators in momentum space have been studied especially in the connection with cosmology, correlators involving a tensor of general spin and scaling dimension have not been studied very much yet. Such a direction is unavoidable when we go beyond three-point functions because general tensors always appear as an intermediate state. In this paper, as a first step, we solve the Ward-Takahashi identities for correlators of a general tensor and conserved currents. In particular we provide their expression in terms of the so-called triple-$K$ integrals and a differential operator which relates triple-$K$ integrals with different indices. For several correlators, closed forms without the differential operator are also found.

description: The Hamburg Open Science program aims to develop an open science infrastructure for universities in Hamburg. This includes open access repositories, research data repositories and research information systems. With limited programming capacities available Hamburg University of Technology opted for an integrated approach instead of three different systems. The current open access repository (based on DSpace-CRIS and fully ORCID-enabled) has been extended with a research data repository and is supposed to include all institutional researchers, organization units, projects and publication information building a research information system and a university bibliography.
 This poster illustrates the components of our extended repository and shows how DSpace-CRIS, an open source software with a vibrant community, helped us cover the two new components of the repository.

description: We describe the motion of a particle in a central field in an expanding universe. Use is made of a double expansion in 1/c and 1/T, where c and T are the speed of light and the Hubble time. In the lowest approximation the fourth power of the rotational velocity is shown to be proportional to (2/3)GMcHo, where G is Newton's gravitational constant, M is the mass of the central body (galaxy) and Ho is the Hubble constant. This formula satisfies observations of stars moving in spiral and elliptical galaxies, and in accordance with the familiar Tully-Fisher law.

I also show that the weakness of the link with the geometric content of the theory gives rise to what I think is a serious flaw in the claimed derivation of a discrete structure for space at the quantum level.

description: Application of deep convolutional spiking neural networks (SNNs) to artificial intelligence (AI) tasks has recently gained a lot of interest since SNNs are hardware-friendly and energy-efficient. Unlike the non-spiking counterparts, most of the existing SNN simulation frameworks are not practically efficient enough for large-scale AI tasks. In this paper, we introduce SpykeTorch, an open-source high-speed simulation framework based on PyTorch. This framework simulates convolutional SNNs with at most one spike per neuron and the rank-order encoding scheme. In terms of learning rules, both spike-timing-dependent plasticity (STDP) and reward-modulated STDP (R-STDP) are implemented, but other rules could be implemented easily. Apart from the aforementioned properties, SpykeTorch is highly generic and capable of reproducing the results of various studies. Computations in the proposed framework are tensor-based and totally done by PyTorch functions, which in turn brings the ability of just-in-time optimization for running on CPUs, GPUs, or Multi-GPU platforms.

description: We study analytically and numerically the role of temperature shifts in the simplest model where the energy landscape is explicitely hierarchical, namely the Sinai model. This model has both attractive features (there are valleys within valleys in a strict self similar sense), but also one important drawback: there is no phase transition so that the model is, in the large size limit, effectively at zero temperature. We compute various static chaos indicators, that are found to be trivial in the large size limit, but exhibit interesting features for finite sizes. Correspondingly, for finite times, some interesting rejuvenation effects, related to the self similar nature of the potential, are observed. Still, the separation of time scales/length scales with temperatures in this model is much weaker that in experimental spin-glasses.

description: In the article, Hall (1910) wrote about the development of Multiceps multiceps in the organism of dogs, which are the main spreaders of the disease of cenurosis, and the fact that dogs are the main cause of the spread of this disease, 100 years ago. According to him, multiceps develops only in the dog's intestine. That's why it was noted that dogs play an important role in the origin and development of cenurosis. Among the regions, the multiceps infection of dogs was more common in the mountain-foreland region, and in the desert region, the results of the infection of herd dogs, the infection of village dogs, and the results of the infection depending on the seasons were highlighted. The work of the authors clearly shows that the animals belonging to the dog family, that is, wolves, foxes, jackals and cats, play a secondary role in the spread of the disease, and that they do not have an important role in the spread of cenurosis in nature.

description: This research examines how two prominent foundations (the Bill & Melinda Gates Foundation and Lumina Foundation) identify problems, develop potential solutions, and attempt to foster their adoption across states and higher education institutions. As foundations play an increasingly central role in shaping how education institutions are funded, how they deliver course content, structure academic programs, and deliver student support services, the importance of these questions increases as well.
      This study draws on interviews with current and former foundation employees, as well as interviews with actors in consulting, advocacy, policy and research organizations, and extensive document analysis, to look beyond the foundations’ financial investments to examine how foundations and their grantees develop policy goals, strategies, and seek to affect education policy through ideas, research, and advocacy.
      This study finds that foundations are undergoing a policy learning process, whereby they modify strategies based on new information, input from partner organizations, and past investments. Limits and challenges to this process are also observed. How foundations grapple with new information is important, because this study also finds that foundations are influential political actors within the higher education completion agenda. In partnership with intermediary organizations, foundations raise awareness of their goals, problem definitions, and solutions, and take an active role in seeking out support for their higher education agendas, affecting both state policy and higher education institutions.

Henretta Creek and Lake : a decade of reclamation monitoring

Publisher: name: The University of British Columbia
Year: 2012

description: This paper presents the vegetation restoration results of a 10 year monitoring project along the reclaimed Henretta Channel and Lake at Teck Coal’s Fording River Operations in southeastern British Columbia. Vegetation monitoring utilized permanent vegetation plots and photo points to assess vegetation restoration success. Heavy metal uptake by vegetation utilized by wildlife was also analyzed for four species: Salix bebbiana, Populus trichocarpa, Medicago sativa, and Festuca spp. Results in 2010 indicated that vegetation was at early- to mid-seral stages on average and showed good growth, vigour, diversity, and natural regeneration since initial seeding and planting. The heavy metal analysis of vegetation tissue found no significant difference between the study site and the control site (no mine influence). A qualitative Proper Functioning Condition (PFC) analysis indicated lotic and lentic areas were functioning properly and showing steady improvement over time. Past aquatic habitat monitoring of water quality and benthic assemblages indicated a healthy aquatic system supporting a self-sustaining Westslope cutthroat trout population. Monitoring and PFC analysis allowed for a critical assessment of the restoration success. Findings will help inform various aspects of all future reclamation activities while recommendations specific to stream restoration projects include channel design and integration of riprapped banks.

description: We discuss prospects of searching for a dark photon ($A'$) which serves as mediator between Standard model (SM) particles and light dark matter (LDM) by using the combined results from the NA64 experiment at the CERN SPS running in high-energy electron (NA64e) and muon (NA64$μ$) modes. We discuss the most natural values and upper bounds on the $A'$ coupling constant to LDM and show they are lying in the range accessible at NA64. While for the projected $ 5\times10^{12}$ electrons on target (EOT) NA64e is able to probe the scalar and Majorana LDM scenarios, the combined NA64e and NA64$μ$ results with $\simeq 10^{13}$ EOT and a few $10^{13}$ MOT, respectively, will allow covering significant region in the parameter space of the most interesting LDM models. This makes NA64e and NA64$μ$ extremely complementary to each other and increases significantly the discovery potential of sub-GeV DM.

description: The probabilities for gaps in the eigenvalue spectrum of the finite dimension $ N \times N $ random matrix Hermite and Jacobi unitary ensembles on some single and disconnected double intervals are found. These are cases where a reflection symmetry exists and the probability factors into two other related probabilities, defined on single intervals. Our investigation uses the system of partial differential equations arising from the Fredholm determinant expression for the gap probability and the differential-recurrence equations satisfied by Hermite and Jacobi orthogonal polynomials. In our study we find second and third order nonlinear ordinary differential equations defining the probabilities in the general $N$ case. For N=1 and N=2 the probabilities and thus the solution of the equations are given explicitly. An asymptotic expansion for large gap size is obtained from the equation in the Hermite case, and also studied is the scaling at the edge of the Hermite spectrum as $ N \to \infty $, and the Jacobi to Hermite limit; these last two studies make correspondence to other cases reported here or known previously. Moreover, the differential equation arising in the Hermite ensemble is solved in terms of an explicit rational function of a {Painlevé-V} transcendent and its derivative, and an analogous solution is provided in the two Jacobi cases but this time involving a {Painlevé-VI} transcendent.

Subjects: subject: Social service
subject: Political science
subject: FOS: Political science

description: This dissertation addresses two issues. One is the means by which particular policy science concepts and technologies inform social workers functioning as analysts of social policy. The second is the caveat of social work regarding the analysis and development of social policy.

Because, among social scientists, economists, systems analysts, political scientists, and policy scientists most frequently contribute to the development and analysis of social policy, their disciplines have been chosen for study. The concepts and perspectives unique to each have been described with regard to how they are applied to the development
of social policy.

The first element of the study design is the introduction of the concepts, techniques and perspectives of economics, systems analysis, political science, and the policy sciences as they are pertinent to the development of social policy. Policy analyses are presented illustratively in order
to stress discipline-based differences in methodological and/or conceptual foci. Distinctive underlying decision-rules by which policy choices are made by different analysts are described.

The study is also designed to explore means by which the knowledge and skill base of the policy sciences can be useful to a social worker in the role of policy analyst. Concepts, techniques and underlying decision rules are presented as they can be "borrowed" by social workers who analyze policy.

Finally, an interpretation of the role of the social worker as policy analyst is presented. The strengths and limitations of each macroscience are
recapitulated. The synthesizing of concepts and methods of inquiry that are relevant to the analysis and development of social policy is elucidated.
Trigonometry of spacetimes: a new self-dual approach to a curvature/signature (in)dependent trigonometry

description: A new method to obtain trigonometry for the real spaces of constant curvature and metric of any (even degenerate) signature is presented. The method encapsulates trigonometry for all these spaces into a single basic trigonometric group equation. This brings to its logical end the idea of an absolute trigonometry, and provides equations which hold true for the nine two-dimensional spaces of constant curvature and any signature. This family of spaces includes both relativistic and non-relativistic homogeneous spacetimes; therefore a complete discussion of trigonometry in the six de Sitter, minkowskian, Newton--Hooke and galilean spacetimes follow as particular instances of the general approach. Any equation previously known for the three classical riemannian spaces also has a version for the remaining six spacetimes; in most cases these equations are new. Distinctive traits of the method are universality and self-duality: every equation is meaningful for the nine spaces at once, and displays explicitly invariance under a duality transformation relating the nine spaces. The derivation of the single basic trigonometric equation at group level, its translation to a set of equations (cosine, sine and dual cosine laws) and the natural apparition of angular and lateral excesses, area and coarea are explicitly discussed in detail. The exposition also aims to introduce the main ideas of this direct group theoretical way to trigonometry, and may well provide a path to systematically study trigonometry for any homogeneous symmetric space.

description: Pro‐choice organizations claim that by 2014, over half of the twenty health centers providing abortions in Virginia will be forced to discontinue services as a result of a regulation categorizing these facilities as hospitals. Proponents of the regulation claim its purpose is to increase patient safety; however, higher‐risk medical procedures, such as cosmetic and dental surgeries, are not subject to similar regulatory scrutiny. This investigation seeks to understand general conditions under which the categorization of abortion providers as hospitals impacts operational costs, as well as bars entry of new providers into the market. Using Virginia as a case study, it also specifically explores how local politics impacts the implementation of health planning, policies, and regulations.

description: The quantum spin Hall (QSH) state was recently demonstrated in monolayers of the transition metal dichalcogenide 1T'-WTe$_2$ and is characterized by a band gap in the two-dimensional (2D) interior and helical one-dimensional (1D) edge states. Inducing superconductivity in the helical edge states would result in a 1D topological superconductor, a highly sought-after state of matter. In the present study, we use a novel dry-transfer flip technique to place atomically-thin layers of WTe$_2$ on a van der Waals superconductor, NbSe$_2$. Using scanning tunneling microscopy and spectroscopy (STM/STS), we demonstrate atomically clean surfaces and interfaces and the presence of a proximity-induced superconducting gap in the WTe$_2$ for thicknesses from a monolayer up to 7 crystalline layers. At the edge of the WTe$_2$ monolayer, we show that the superconducting gap coexists with the characteristic spectroscopic signature of the QSH edge state. Taken together, these observations provide conclusive evidence for proximity-induced superconductivity in the QSH edge state in WTe$_2$, a crucial step towards realizing 1D topological superconductivity and Majorana bound states in this van der Waals material platform.

For an entropic index q>1 the multiplicity distribution is wider than the Poisson distribution with the same average number of particles, being similar to the negative binomial distribution commonly used in phenomenological analysis of hadron production in high-energy collisions.

description: Genus Zepherina Bechyné, 1958
Zepherina Bechyné, 1958: 590 (type species Malacosoma bellum Bowditch, 1925, by original designation).
Remarks
This genus is reported to occur in Central and South America. An undescribed species from the Bahamas may also belong here. However, the genus is composed of a heterogeneous mixture of species. Most notably, the aedeagi vary dramatically in form. The beetles are also very heterogeneous in their externally visible characters (hence, the numerous places the genus appears in the key). Future systematic study will surely result in the genus being subdivided into numerous smaller genera. The following key accounts for much of the heterogeneity, but may not allow for identification of all of the species currently in the genus. Moreover, minimal characters differentiate Zepherina from Masurius. Some of the species currently placed in Zepherina might more properly belong in Masurius. Together, the two genera currently contain approximately 60 named species. See Figs 52–55 and 155 for illustrations of Zepherina.

Integration in the GHP formalism III: Finding all conformally flat radiation metrics as an example of an `optimal situation'

description: Held has proposed an integration procedure within the GHP formalism built around four real, functionally independent, zero-weighted scalars. He suggests that such a procedure would be particularly simple for the `optimal situation', when the formalism directly supplies the full quota of four scalars of this type; a spacetime without any Killing vectors would be such a situation. Wils has recently obtained a metric which he claims is the only conformally flat, pure radiation metric which is not a plane wave; this metric has been shown by Koutras to admit no Killing vectors, in general. Therefore, as a simple illustration of the GHP integration procedure, we obtain systematically the complete class of conformally flat, pure radiation metrics. Our result shows that the conformally flat, pure radiation metrics, which are not plane waves, are a larger class than Wils has obtained.

Modeling Acoustic-Prosodic Cues for Word Importance Prediction in Spoken Dialogues

description: Prosodic cues in conversational speech aid listeners in discerning a message. We investigate whether acoustic cues in spoken dialogue can be used to identify the importance of individual words to the meaning of a conversation turn. Individuals who are Deaf and Hard of Hearing often rely on real-time captions in live meetings. Word error rate, a traditional metric for evaluating automatic speech recognition, fails to capture that some words are more important for a system to transcribe correctly than others. We present and evaluate neural architectures that use acoustic features for 3-class word importance prediction. Our model performs competitively against state-of-the-art text-based word-importance prediction models, and it demonstrates particular benefits when operating on imperfect ASR output.

Constraining compact star properties with nuclear saturation parameters

description: A set of hadronic equations of state (EoSs) derived from relativistic density functional theory and constrained by terrestrial experiments, astrophysical observations, in particular by the GW170817 event, and chiral effective field theory ($χ$EFT) of neutron matter is used to explore the sensitivity of the EoS parameterization on the few nuclear matter characteristics defined at the saturation density. We find that the gross properties of compact stars are most sensitive to the isoscalar skewness coefficient $Q_{\text{sat}}$ and the isovector slope coefficient $L_{\text{sym}}$ around saturation density, since the higher order coefficients, such as $K_{\text{sym}}$, are fixed by our model. More specifically, (i) among these $Q_{\text{sat}}$ is the dominant parameter controlling both the maximum mass and the radii of compact stars while $L_{\rm sym}$ is constrained somewhat by $χ$EFT of neutron matter; (ii) massive enough ($M\sim 2.0~M_{\odot})$ compact stars featuring both hyperons and $Δ$ resonances can be obtained if the value of $Q_{\text{sat}}$ is large enough; (iii) the emergence of $Δ$'s reduces the radius of a canonical mass ($M\sim 1.4~M_{\odot})$ compact star thus easing the tension between the predictions of the relativistic density functionals and the inferences from the X-ray observation of nearby isolated neutron stars.

Absence of First-order Transition and Tri-critical Point in the Dynamic Phase Diagram of a Spatially Extended Bistable System in an Oscillating Field

description: It has been well established that spatially extended, bistable systems that are driven by an oscillating field exhibit a nonequilibrium dynamic phase transition (DPT). The DPT occurs when the field frequency is on the order of the inverse of an intrinsic lifetime associated with the transitions between the two stable states in a static field of the same magnitude as the amplitude of the oscillating field. The DPT is continuous and belongs to the same universality class as the equilibrium phase transition of the Ising model in zero field [G. Korniss et al., Phys. Rev. E 63, 016120 (2001); H. Fujisaka et al., Phys. Rev. E 63, 036109 (2001)]. However, it has previously been claimed that the DPT becomes discontinuous at temperatures below a tricritical point [M. Acharyya, Phys. Rev. E 59, 218 (1999)]. This claim was based on observations in dynamic Monte Carlo simulations of a multipeaked probability density for the dynamic order parameter and negative values of the fourth-order cumulant ratio. Both phenomena can be characteristic of discontinuous phase transitions. Here we use classical nucleation theory for the decay of metastable phases, together with data from large-scale dynamic Monte Carlo simulations of a two-dimensional kinetic Ising ferromagnet, to show that these observations in this case are merely finite-size effects. For sufficiently small systems and low temperatures, the continuous DPT is replaced, not by a discontinuous phase transition, but by a crossover to stochastic resonance. In the infinite-system limit the stochastic-resonance regime vanishes, and the continuous DPT should persist for all nonzero temperatures.
Spectrum generating algebra and coherent states of the $C_λ$-extended oscillator

description: $C_λ$-extended oscillator algebras, generalizing the Calogero-Vasiliev algebra, where $C_λ$ is the cyclic group of order $λ$, have recently proved very useful in the context of supersymmetric quantum mechanics and some of its variants. Here we determine the spectrum generating algebra of the $C_λ$-extended oscillator. We then construct its coherent states, study their nonclassical properties, and compare the latter with those of standard $λ$-photon coherent states, which are obtained as a special case. Finally, we briefly review some other types of coherent states associated with the $C_λ$-extended oscillator.

Political Mormonism From Joseph Smith to Mitt Romney, 1844-2012

description: An analysis into the political development of the Latter-day Saint (Mormon) movement from Joseph Smith until the candidacy of Mitt Romney. The basic inquiry attached to analyzing Political Mormonism is fundamentally twofold: exploring the why of political Mormonism as well as how it came to its current station in America. Both seek to understand the operative function of Mormon political behaviors, while exploring the unique position Mormons hold in the American experiment. By looking at the evolution of normative Mormon political output, we come to understand the important and contemporary role Mormons hold in the American polity.

Knots in Charged Polymers

description: The interplay of topological constraints and Coulomb interactions in static and dynamic properties of charged polymers is investigated by numerical simulations and scaling arguments. In the absence of screening, the long-range interaction localizes irreducible topological constraints into tight molecular knots, while composite constraints are factored and separated. Even when the forces are screened, tight knots may survive as local (or even global) equilibria, as long as the overall rigidity of the polymer is dominated by the Coulomb interactions. As entanglements involving tight knots are not easy to eliminate, their presence greatly influences the relaxation times of the system. In particular, we find that tight knots in open polymers are removed by diffusion along the chain, rather than by opening up. The knot diffusion coefficient actually decreases with its charge density, and for highly charged polymers the knot's position appears frozen.

Remarks
This genus contains about 80 described species. They are distributed from Canada through much of South America, as well as in West Indies. See Figs 77–78 for habitus illustrations. See Bechyné (1958), Bechyné & Bechyné (1968), Munroe & Smith (1980), and Cabrera (1999) for keys to many of the species. Some of the smaller beetles are very similar to some of the small Isotes, and their generic placements warrant reevaluation.
