description: We report the detection of Lyman Continuum (LyC) emission from the galaxy, CDFS-6664, at z=3.797 in a sample of Lyman break galaxies with detected [OIII] emission lines. The LyC emission is detected with a significance ~$5σ$ in the F336W band of the Hubble Deep UV Legacy Survey, corresponding to the 650-770 Angstrom rest-frame. The light centroid of the LyC emission is offset from the galaxy center by about 0.2" (1.4 pkpc). The Hubble deep images at longer wavelengths show that the emission is unlikely provided by low-redshift interlopers. The photometric and spectroscopic data show that the possible contribution of an active galactic nucleus is quite low. Fitting the spectral energy distribution of this source to stellar population synthesis models, we find that the galaxy is young (~50 Myr) and actively forming stars with a rate of 52.1$\pm$4.9 $M_{\odot}\mathrm{yr^{-1}}$. The significant star formation and the spatially offset LyC emission support a scenario where the ionizing photons escape from the low-density cavities in the ISM excavated by massive young stars. From the nebular model, we estimate the escape fraction of LyC photons to be 38$\pm$7% and the corresponding IGM transmission to be 60%, which deviates more than 3$σ$ from the average transmission. The unusually high IGM transmission of LyC photons in CDFS-6664 may be related to a foreground type-2 quasar, CDF-202, at z=3.7, with a projected separation of 1.2' only. The quasar may have photoevaporated optically thick absorbers and enhance the transmission on the sightline of CDFS-6664.

Publisher: name: Utah State University

description: SNAP reduces space mission cost by providing an advanced modular, open systems approach to software. As part of the space modernization efforts, SMC is sponsoring an effort to develop advanced network architectures for spacecraft systems. Government and DoD agencies are looking to the hosted payload concept to reduce space mission cost in the current budget constrained environment. The hosted payload paradigm poses significant system integration challenges due to payloads being developed independently of the host spacecraft. SNAP is an adapter that uses software and hardware interfaces to provide network connectivity and protocol translation to integrate a spacecraft and payload. In addition to solving the systems integration problems associated with the hosted payload concept, SNAPs advanced modular, open systems approach results in reduced overall cost and length of development for spacecraft systems. SNAP has been demonstrated with the Operationally Responsive Space (ORS) offices Modular Space Vehicle (MSV) and three different payloads. This document provides a system level overview of the SNAP architecture and the design concepts used in its development.
title: Interpolation and Validation of Arced Labyrinth Weir Discharge Coefficients
Creators: name: Thurgood, Rhen Daniel
Publisher: name: Utah State University
Year: 2014

description: Arced labyrinth weirs have been researched in recent years as a viable option to help increase spillway discharge capacity. Previously published data have indicated the hydraulic efficiency of these weirs with several configurations at different sidewall angles (α=6°, α=12°, and α=20°), expressed in terms of the discharge coefficients. These published discharge coefficient data were used in the current study, along with new experimental data, to develop a better understanding of the accuracy associated with interpolating arced labyrinth weir discharge coefficients. Discharge coefficient data for a 16° arced labyrinth weir (of similar physical size to the arced labyrinth weirs in the literature) were determined as part of a physical model study. The α=16° experimental discharge coefficient data were compared against interpolated data using the α=12° and 20° published data using two interpolation methods, linear and double spline interpolation. It was concluded that the double spline interpolation data more accurately matched the experimental data and is recommended as the preferred method for interpolating between arced labyrinth weir discharge coefficients. Interpolating proved to perform well for a first-order approximation. The reservoir approach flow conditions for this model study are examined and compared with the simplified previously published approach flow conditions.

description: We investigate the internal 3D magnetic structure of dense interstellar filaments within NGC 1333 using polarization data at $850 μ\mathrm{m}$ from the $B$-fields In STar-forming Region Observations survey at the James Clerk Maxwell Telescope. Theoretical models predict that the magnetic field lines in a filament will tend to be dragged radially inward (i.e., pinched) toward the central axis due to the filament's self-gravity. We study the cross-sectional profiles of the total intensity ($I$) and polarized intensity (PI) of dust emission in four segments of filaments unaffected by local star formation that are expected to retain a pristine magnetic field structure. We find that the filaments' FWHM in PI are not the same as those in $I$, with two segments being appreciably narrower in PI (FWHM ratio $\simeq 0.7-0.8$) and one segment being wider (FWHM ratio $\simeq 1.3$). The filament profiles of the polarization fraction ($P$) do not show a minimum at the spine of the filament, which is not in line with an anticorrelation between $P$ and $I$ normally seen in molecular clouds and protostellar cores. Dust grain alignment variation with density cannot reproduce the observed $P$ distribution. We demonstrate numerically that the $I$ and PI cross-sectional profiles of filaments in magnetohydrostatic equilibrium will have differing relative widths depending on the viewing angle. The observed variations of FWHM ratios in NGC 1333 are therefore consistent with models of pinched magnetic field structures inside filaments, and especially if they are magnetically near-critical or supercritical.

description: I consider constraints on a phenomenological decaying-dark-matter model, in which two weakly-interacting massive particle (WIMP) species have a small mass splitting, and in which the heavier particle decays to the lighter particle and a massless particle on cosmological timescales. The decay parameter space is parameterized by $v_k$, the speed of the lighter particle in the center-of-mass frame of the heavier particle prior to decay, and the decay time $τ$. Since I consider the case in which dark-matter halos have formed before there has been significant decay, I focus on the effects of decay in already-formed halos. I show that the $v_k-τ$ parameter space may be constrained by observed properties of dark-matter halos. I highlight which set of observations is likely to yield the cleanest constraints on $v_k-τ$ parameter space, and calculate the constraints in those cases in which the effect of decay on the observables can be calculated without N-body simulations of decaying dark matter. I show that for $v_k \gtrsim 5\times 10^3$ km s$^{-1}$, the z=0 galaxy cluster mass function and halo mass-concentration relation constrain $τ\gtrsim$ 40 Gyr, and that precise constraints on $τ$ for smaller $v_k$ will require N-body simulations.

description: Radio, infrared, and optical observations of the 2006 eruption of the symbiotic recurrent nova RS Ophiuchi (RS Oph) showed that the explosion produced non-spherical ejecta. Some of this ejected material was in the form of bipolar jets to the east and west of the central source. Here we describe Xray observations taken with the Chandra X-ray Observatory one and a half years after the beginning of the outburst that reveal narrow, extended structure with a position angle of approximately 300 degrees (east of north). Although the orientation of the extended feature in the X-ray image is consistent with the readout direction of the CCD detector, extensive testing suggests that the feature is not an artifact. Assuming it is not an instrumental effect, the extended X-ray structure shows hot plasma stretching more than 1,900 AU from the central binary (taking a distance of 1.6 kpc). The X-ray emission is elongated in the northwest direction - in line with the extended infrared emission and some minor features in the published radio image. It is less consistent with the orientation of the radio jets and the main bipolar optical structure. Most of the photons in the extended X-ray structure have energies of less than 0.8 keV. If the extended X-ray feature was produced when the nova explosion occurred, then its 1".2 length as of 2007 August implies that it expanded at an average rate of more than 2 mas/d, which corresponds to a flow speed of greater than 6,000 km/s (d/1.6 kpc) in the plane of the sky. This expansion rate is similar to the earliest measured expansion rates for the radio jets.

title: The Empirical Study of Size Effect, Book-to-Market Effect in US Security Market
Creators: name: Zhao, Zhe

description: Banz (1981) found size effect using data over the period 1926–1975. This paper uses data from last 33 years from NYSE, Amex, and Nasdaq to test the existence of size effect and book-to-market effect. In this paper data is sorted by size and book-to-market ratio across quintiles. I runs the time-series regression taking advantage of CAPM model, Fama-French 3-factor model and Carhart 4-factor model to get three different alpha. With all next-month returns, this paper compares those low size/book-to-market next-month returns with those high size/book-to-market next-month returns and uses t-test to verify the existence of these two effects. This paper indicates that B/M (book-to-market) effect still exists. However, size effect does not exist anymore without the tiny firms (with their stock price under $5). In 1980-1990 period, the big-size firm outperform small-size firm by 0.26 percent.

In particular, we give analogous definitions of even and odd Coleman maps for normalised new forms of arbitrary weights and relate Pollack's $p$-adic $L$-functions to the even and odd Selmer groups. In addition, by generalising works of Pollack and Rubin on CM elliptic curves, we prove the "main conjecture" for CM modular forms.

title: Implementation of Effective Instructional Routines, Praise Statements, Response Opportunities, and Error Correction through Professional Training, Coaching and Observation
Creators: name: Richardson, Sallie
Publisher: name: Utah State University
Year: 2014

description: Professional development opportunities can range from a single workshop to long term ongoing training. Research shows that an inspiring and informed teacher is one of the most important school related factor influencing student achievement. The best professional development for new teachers is ongoing, experiential, and collaborative, while providing an opportunity for practice, reflecting and mentoring for successful development. Most professionals involved in professional development would agree that the goal of staff development is to produce a change in participant’s knowledge, behaviors, understanding, skills, values, and beliefs (Hord, S. & Monk, B. 1997). The purpose of this creative project was to evaluate the effectiveness of professional development and observations on the implementation of instructional routines and response opportunities. Participants learned how to effectively introduce reading and writing skills during small group using instructional routines and to provide response opportunities for teachers and students. The professional development outcome was measured with an instructional routine observation form that focused on 8 instructional routine procedures and a response opportunity observation form that focused on praise statements, opportunities for student response and error correction procedures. Trainees also took an effective instructional practice pre-post quiz and completed a professional development questionnaire at the conclusion of training.

description: Fairy tales are an integral part of our culture and have been for hundreds of years. Most of us grew up hearing certain stories, reading the Grimm brothers, watching Disney adaptations of classic tales, and passing these things on to the next generation. But even though we sometimes dismiss fairy tales as we get older as “stories for children,” that does not mean that fairy tales do not play an important role in our lives and cultures. Studying and understanding fairy tales can provide insight into our history, our cultures, and ourselves. As stated by Dan Ben-Amos, “The folktale has found its way into new realms and adapted to modern means of communication [and] the traditional folktale has been subjected to an array of criticisms” (qtd. in Rohrich xx). Scholars are continually looking for new approaches to folklore criticism to help us understand both how and why fairy tales are still relevant, which is why I am studying fairy tales from a rhetorical perspective.
Gödel black hole, closed timelike horizon, and the study of particle emissions

Year: 2009

description: We show that a particle, with positive orbital angular momentum, following an outgoing null/timelike geodesic, shall never reach the closed timelike horizon (CTH) present in the $(4+1)$-dimensional rotating Gödel black hole space-time. Therefore a large part of this space-time remains inaccessible to a large class of geodesic observers, depending on the conserved quantities associated with them. We discuss how this fact and the existence of the closed timelike curves present in the asymptotic region make the quantum field theoretic study of the Hawking radiation, where the asymptotic observer states are a pre-requisite, unclear. However, the semiclassical approach provides an alternative to verify the Smarr formula derived recently for the rotating Gödel black hole. We present a systematic analysis of particle emissions, specifically for scalars, charged Dirac spinors and vectors, from this black hole via the semiclassical complex path method.

description: The minimum distance graph of a code has the codewords as vertices and edges exactly when the Hamming distance between two codewords equals the minimum distance of the code. A constructive proof for reconstructibility of an extended perfect binary one-error-correcting code from its minimum distance graph is presented. Consequently, inequivalent such codes have nonisomorphic minimum distance graphs. Moreover, it is shown that the automorphism group of a minimum distance graph is isomorphic to that of the corresponding code.

A review and analysis of the literature related to critical reading and a handbook to develop specific critical reading skills
Creators: name: Carson, Nancy Lynne
Publisher: name: University of British Columbia
Year: 2010

description: This thesis presents a review and analysis of the literature on critical reading, and a handbook designed to assist teachers who wish to improve their teaching of critical reading skills. The relationship between critical reading and reading comprehension is explored under the topic headings of cognitive models, factor analytic studies and models of reading behaviors. It was found that a strong relationship exists between critical reading and thinking, and that some educators recommend the teaching of critical reading skills as a vehicle for developing critical thinking skills. This review indicates that despite evidence which suggests a need for specific teaching of critical reading skills, and despite evidence which indicates the value of teacher questioning in developing these skills, the latter technique is not being well utilized at the present time. Some educators suggest that this situation exists because reading educators express "vague and ambiguous" concepts of this aspect of reading comprehension. General definitions of critical reading indicate that it involves some evaluation of material based on criteria formed by previous reading background and experience. It is difficult to establish the exact subskills involved, but major educators appear to agree that there are four subskills that seem basic to critical reading. These subskills are: 1) fact or opinion, 2) evaluation of characters' actions and speech, J>) inference, k) establishing the author's purpose. The handbook is designed to develop the four specific critical reading skills identified above. Questions are based on stories selected from four basal readers authorized for use in British Columbia schools. The Dale-Chall readability levels are provided for each story, and a foreword to teachers includes suggestions for utilizing the handbook.

"Hard-scattering" approach to very hindered magnetic-dipole transitions in quarkonium

description: For a class of hindered magnetic dipole ($M1$) transition processes, such as $Υ(3S)\to η_b+γ$ (the discovery channel of the $η_b$ meson), the emitted photon is rather energetic so that the traditional approaches based on multipole expansion may be invalidated. We propose that a "hard-scattering" picture, somewhat analogous to the pion electromagnetic form factor at large momentum transfer, may be more plausible to describe such types of transition processes. We work out a simple factorization formula at lowest order in the strong coupling constant, which involves convolution of the Schrödinger wave functions of quarkonia with a perturbatively calculable part induced by exchange of one semihard gluon between quark and antiquark. This formula, without any freely adjustable parameters, is found to agree with the measured rate of $Υ(3S)\to η_b+γ$ rather well, and can also reasonably account for other recently measured hindered $M1$ transition rates. The branching fractions of $Υ(4S)\to η_b^{(\prime)}+γ$ are also predicted.

We explicitly realize a map between X and the total space of the canonical bundle over a degree 1 quasi del Pezzo surface, thus defining a desingularization of X. Our analysis relys essentially on the relationship existing between the normalizer group of D_27 and the Hessian group and on the study of the behaviour of the Hesse pencil of plane cubic curves under the quotient.

Danach kann eine Organisation nur überleben, wenn es ihr gelingt, den Systemanforderungen, die sich auf Or-ganisationen richten, zu genügen. Veränderungen von Systemanforderungen bewirken daher An-passungsreaktionen, die allerdings nicht reibungslos ablaufen. Das Modell beschreibt den Verhal-tensprozess, der durch ein gestörtes Systemgleichgewicht ausgelöst wird. Als Modellvariable fun-gieren die Systemanforderungen und das zu seiner Bewältigung implementierte Institutionelle Ar-rangement sowie außerdem Sensitivität, Handlungsbereitschaft, Beharrung, Realismus, Identifika-tion, Handlungsdruck, Unsicherheit, Dysfunktion und Dissonanz. Die Simulationsrechnungen zei-gen, wie sich aus den jeweiligen Variablenkonstellationen bestimmte Verhaltensmuster herausbil-den und welche Mechanismen dafür verantwortlich sind.

description: $LiHo_xY_{1-x}F_4$ is an insulating system where the magnetic Ho$^{3+}$ ions have an Ising character, and interact mainly through magnetic dipolar fields. We used the muon spin relaxation technique to study the nature of the ground state for samples with x=0.25, 0.12, 0.08, 0.045 and 0.018. In contrast with some previous works, we have not found any signature of canonical spin glass behavior down to $\approx$15mK. Instead, below $\approx$300mK we observed dynamic magnetism characterized by a single correlation time with a temperature independent fluctuation rate. We observed that this low temperature fluctuation rate increases with x up to 0.08, above which it levels off. The 300mK energy scale corresponds to the Ho3+ hyperfine interaction strength, suggesting that the hyperfine interaction may be intimately involved with the spin dynamics in this system.

The survey looks at researchers' motivations for publishing a book, and analyses the parameters and key drivers which influence academics to publish OA or not. The white paper also identifies the major obstacles to OA publication which book authors still face: from a lack of awareness of OA publishing options and low funding, to concerns about how OA books are perceived.
2,542 book authors completed the survey which ran for two weeks in February and March 2019.

description: Gauge fixing in the non-perturbative domain of non-Abelian gauge theories is obstructed by the Gribov-Singer ambiguity. To compare results from different methods it is necessary to resolve this ambiguity explicitly. Such a resolution is proposed using conditions on correlation functions for a family of non-perturbative Landau gauges. As a consequence, the various results available for correlation functions could possibly correspond to different non-perturbative Landau gauges, discriminated by an additional non-perturbative gauge parameter. The proposal, the necessary assumptions, and evidence from lattice gauge theory calculations, are presented in detail.

description: The substantial progress that has been achieved in lattice QCD in the last years is pointed out. I compare the simulation cost and systematic effects of several lattice QCD formulations and discuss a number of topics such as lattice spacing scaling, applications of chiral perturbation theory, non-perturbative renormalization and finite volume effects. Additionally, the importance of demonstrating universality is emphasized.

description: A learning method is self-certified if it uses all available data to simultaneously learn a predictor and certify its quality with a tight statistical certificate that is valid on unseen data. Recent work has shown that neural network models trained by optimising PAC-Bayes bounds lead not only to accurate predictors, but also to tight risk certificates, bearing promise towards achieving self-certified learning. In this context, learning and certification strategies based on PAC-Bayes bounds are especially attractive due to their ability to leverage all data to learn a posterior and simultaneously certify its risk with a tight numerical certificate. In this paper, we assess the progress towards self-certification in probabilistic neural networks learnt by PAC-Bayes inspired objectives. We empirically compare (on 4 classification datasets) classical test set bounds for deterministic predictors and a PAC-Bayes bound for randomised self-certified predictors. We first show that both of these generalisation bounds are not too far from out-of-sample test set errors. We then show that in data starvation regimes, holding out data for the test set bounds adversely affects generalisation performance, while self-certified strategies based on PAC-Bayes bounds do not suffer from this drawback, proving that they might be a suitable choice for the small data regime. We also find that probabilistic neural networks learnt by PAC-Bayes inspired objectives lead to certificates that can be surprisingly competitive with commonly used test set bounds.

description: Non-monotonic dependence of anomalous Hall resistivity on temperature and magnetization, including a sign change, was observed in Fe/Gd bilayers. To understand the intriguing observations, we fabricated the Fe/Gd bilayers and single layers of Fe and Gd simultaneously. The temperature and field dependences of longitudinal resistivity, Hall resistivity and magnetization in these films have also been carefully measured. The analysis of these data reveals that these intriguing features are due to the opposite signs of Hall resistivity/or spin polarization and different Curie temperatures of Fe and Gd single-layer films.

description: The ABALONE is a new type of photosensor produced by PhotonLab, Inc. with cost effective mass production, robustness and high performance. This modern technology provides sensitivity to visible and UV light, exceptional radio-purity and excellent detection performance in terms of intrinsic gain, afterpulsing rate, timing resolution and single-photon sensitivity. For these reasons, the ABALONE can have many fields of application, including particle physics experiments, such as DARWIN, and medical imaging. This new hybrid photosensor, that works as light intensifier, is based on the acceleration in vacuum of photoelectrons generated in a traditional photosensor cathode and guided towards a window of scintillating material that can be read from the outside through a silicon photomultiplier. In this work we present the simulation of the ABALONE and the results from operation at room temperature. The goal of the characterization is the evaluation of the gain, the response in time and the single photoelectron spectrum as a function of the electric field and the photoelectron emission angle. Details of future tests will be also discussed.

Theory of Thermal Hall Effect in Quantum Magnets

description: We present a theory of the thermal Hall effect in insulating quantum magnets, where the heat current is totally carried by charge-neutral objects such as magnons and spinons. Two distinct types of thermal Hall responses are identified. For ordered magnets, the intrinsic thermal Hall effect for magnons arises when certain conditions are satisfied for the lattice geometry and the underlying magnetic order. The other type is allowed in a spin liquid which is a novel quantum state since there is no order even at zero temperature. For this case, the deconfined spinons contribute to the thermal Hall response due to Lorentz force. These results offer a clear experimental method to prove the existence of the deconfined spinons via a thermal transport phenomenon.

description: The most general spherically symmetric solution with zero shift is found in the non-projectable Horava-Lifshitz class of theories with general coupling constants. It contains as special cases, spherically symmetric solutions found by other authors earlier. It is found that the generic solution has conventional (AdS, dS or flat) asymptotics with a universal 1/r tail. There are several special cases where the asymptotics differ, including the detailed balance choice of couplings. The conventional thermodynamics of this general class of solutions is established by calculating the energy, temperature and entropy. Although several of the solutions have conventional horizons, for particles with ultra-luminal dispersion relations such solutions appear to be horizonless.

description: The shockless explosion combustion (SEC) is a recently proposed concept aiming for pressure gain combustion through an unsteady process of multiple, distributed autoignitions occurring simultaneously. For this, a stratified fuel profile of dimethyl ether is injected into a continuous air flow. This profile is tailored such that the mixture residence time and ignition delay time are matched, allowing multiple ignition kernels to initiate simultaneously leading to an aerodynamic confinement during heat release. This work first presents an injection strategy for injecting a defined mixture profile into a convection air flow to control the local equivalence ratio throughout the combustor. Line-of-sight measurements are applied to visualize the concentration profile and subsequently used to develop a one-dimensional tool to predict the local equivalence ratio before ignition. Next, an extremum seeking control algorithm is applied to an existing SEC test rig to control the cycle averaged formation of different autoignition modes by optimizing the fuel supply. Pressure and ionization probe data indicate the successful initiation of specific modes of flame propagation by adjusting the fuel injection trajectory. The previously developed simulation tool is applied to the injection trajectories optimized by the controller. Correlating the fuel concentration distribution and the obtained autoignition modes reveal that the ignition process can be very well controlled by the fuel injection trajectory. Lastly, single representative ignition cycles are further investigated by applying optical measurement techniques to obtain OH* and CH* chemiluminescence. The results reveal a complex interaction between heat release and pressure waves influenced by temperature-dependent ignition behavior of the applied fuel. As a conclusion, four different flame propagation modes are identified, namely: turbulent deflagration, subsonic autoignition, supersonic autoignition and aerodynamic confinement by multiple simultaneous autoignition fronts.
