description: We study the effect of the meson cloud dressing in the octet baryon to decuplet baryon electromagnetic transitions. Combining the valence quark contributions from the covariant spectator quark model with those of the meson cloud estimated based on the flavor SU(3) cloudy bag model, we calculate the transition magnetic form factors at $Q^2=0$ ($Q^2=-q^2$ and $q$ the four-momentum transfer), and also the decuplet baryon electromagnetic decay widths. The result for the $γ^\ast Λ\to Σ^{\ast 0}$ decay width is in complete agreement with the data, while that for the $γ^\ast Σ^+ \to Σ^{\ast +}$ is underestimated the data by 1.4 standard deviations. This achievement may be regarded as a significant advance in the present theoretical situation.

description: Ta$_2$NiSe$_5$ is an excitonic insulator candidate showing the semiconductor/semimetal-to-insulator (SI) transition below $T_{\text{c}}$ = 326 K. However, since a structural transition accompanies the SI transition, deciphering the role of electronic and lattice degrees of freedom in driving the SI transition has remained controversial. Here, we investigate the photoexcited nonequilibrium state in Ta$_2$NiSe$_5$ using pump-probe Raman and photoluminescence (PL) spectroscopies. The combined nonequilibrium spectroscopic measurements of the lattice and electronic states reveal the presence of a photoexcited metastable state where the insulating gap is suppressed, but the low-temperature structural distortion is preserved. We conclude that electron correlations play a vital role in the SI transition of Ta$_2$NiSe$_5$.

title: Considering sensory processing issues in trauma affected children : the physical environment in children’s residential homes
Creators: name: Robinson, Christopher

description: Sensory processing issues are generally considered to be clinically significant in children who have suffered abuse and trauma and much has been written about the possible neurological correlates of such sensitivities (De Bellis and Thomas, 2003; van der Kolk, 2014). Comparatively little focus has been given to the functional aspects of these sensitivities, and particularly how these might interact, in context, with a child’s underlying neurological vulnerabilities. In this respect, the environment surrounding the child is a neglected area of significant, perhaps critical, importance. In terms of potential hypersensitivity to environmental stimuli, children with Autistic Spectrum Conditions (ASC), although with different aetiological correlates to trauma affected children, are known to face profound environmental challenges. Children with ASCs have received a wealth of attention in the literature with regard to these sensory challenges, whereas, in contrast, trauma affected children have received very little direct attention at all. It is the aim of this paper to focus on the environmental aspects of sensory processing in trauma affected children, specifically in relation to the physical environment of children’s residential homes.

description: We investigate the vibrational properties of topologically disordered materials by analytically studying particles that harmonically oscillate around random positions. Exploiting classical field theory in the thermodynamic limit at $T=0$, we build up a self-consistent model by analyzing the Hessian utilizing Euclidean Random Matrix theory. In accordance with earlier findings [T. S. Grigera et al.J.~Stat.~Mech.~11 (2011) P02015.], we take non-planar diagrams into account to correctly address multiple local scattering events. By doing so, we end up with a first principles theory that can predict the main anomalies of athermal disordered materials, including the boson peak, sound softening, and Rayleigh damping of sound. In the vibrational density of states, the sound modes lead to Debye's law for small frequencies. Additionally, an excess appears in the density of states starting as $ω^4$ in the low frequency limit, which is attributed to (quasi-) localized modes.

description: A key science driver for the next generation of wide-field optical and radio surveys is the exploration of the time variable sky. These surveys will have unprecedented sensitivity and areal coverage, but will be limited in their ability to detect variability on time scales longer than the lifetime of the surveys. We present a new precision, multi-epoch photometric catalog that spans 60 years by combining the USNO-B and SDSS Data Release 9 catalogs. We recalibrate the photometry of the original USNO-B catalog and create a catalog with two epochs of photometry in up to five different bands for 43,647,887 optical point sources that lie in the DR9 footprint of the northern sky. The recalibrated objects span a magnitude range 14 < m < 20 and are accurate to $\approx$ 0.1 mag. We minimize the presence of spurious objects and those with inaccurate magnitudes by identifying and removing several sources of systematic errors in the two originating catalogs, with a focus on spurious objects that exhibit large apparent magnitude variations. After accounting for these effects, we find $\approx$ 250,000 stars and quasars that show significant (> 4$σ$) changes in brightness between the USNO-B and SDSS DR9 epochs. We discuss the historical value of the catalog and its application to the study of long time-scale, large amplitude variable stars and quasars.

description: Manually constructing a Wordnet is a difficult task, needing years of experts' time. As a first step to automatically construct full Wordnets, we propose approaches to generate Wordnet synsets for languages both resource-rich and resource-poor, using publicly available Wordnets, a machine translator and/or a single bilingual dictionary. Our algorithms translate synsets of existing Wordnets to a target language T, then apply a ranking method on the translation candidates to find best translations in T. Our approaches are applicable to any language which has at least one existing bilingual dictionary translating from English to it.

The Rumble in the Meson: a leptoquark versus a $Z^\prime$ to fit $b \rightarrow s μ^+ μ^-$ anomalies including 2022 LHCb $R_{K^{(\ast)}}$ measurements

description: We juxtapose global fits of two bottom-up models (an $S_3$ scalar leptoquark model and a ${B_3-L_2}$ $Z^\prime$ model) of \bsll\ anomalies to flavour data in order to quantify statistical preference or lack thereof. The leptoquark model couples directly to left-handed di-muon pairs, whereas the $Z^\prime$ model couples to di-muon pairs with a vector-like coupling. $B_s-\overline{B_s}$ mixing is a focus because it is typically expected to disfavour $Z^\prime$ explanations. In two-parameter fits to 247 flavour observables, including $B_{s/d} \to μ^+ μ^-$ branching ratios for which we provide an updated combination and LHCb $R_{K^{(\ast)}}$ measurements from December 2022, we show that each model provides a similar improvement in quality-of-fit of $\sqrt{Δχ^2}=3.6$ with respect to the Standard Model. The main effect of the $B_s-\overline{B_s}$ mixing constraint in the $Z^\prime$ model is to disfavour values of the $s_L-b_L$ mixing angle greater than about $5|V_{cb}|$. This limit is rather loose, meaning that a good fit to data does not require `alignment' in either quark Yukawa matrix. No curtailment of the $s_L-b_L$ mixing angle is evident in the $S_3$ model.

description: We report on the first compelling observation of $α$ decay of $^{151}$Eu to the ground state of $^{147}$Pm. The measurement was performed using a 6.15 g Li$_6$Eu(BO$_3$)$_3$ crystal operated as a scintillating bolometer. The Q-value and half-life measured are: Q = 1948.9$\pm 6.9(stat.) \pm 5.1(syst.)$ keV, and T$_{1/2}=\left( 4.62\pm0.95(stat.)\pm0.68(syst.)\right) \times 10^{18}$ y . The half-life prediction of nuclear theory using the Coulomb and proximity potential model are in good agreement with this experimental result.

A group of molecules are decelerated by about 20 m/s by applying light of a fixed frequency for 1.8 ms. Their velocity spread is reduced, corresponding to a final temperature of about 300 mK. The velocity is further reduced by chirping the frequency of the light to keep it in resonance as the molecules slow down.

description: We report the results of our search for the progenitor candidate of SN 2013dk, a Type Ic supernova (SN) that exploded in the Antennae Galaxy system. We compare pre-explosion Hubble Space Telescope (HST) archival images with SN images obtained using adaptive optics at the ESO Very Large Telescope. We isolate the SN position to within 3 sigma uncertainty radius of 0.02", and show that there is no detectable point source in any of the HST filter images within the error circle. We set an upper limit to the absolute magnitude of the progenitor to be M_F555W > -5.7, which does not allow Wolf-Rayet (WR) star progenitors to be ruled out. A bright source appears 0.17" away, which is either a single bright supergiant or compact cluster, given its absolute magnitude of M_F555W=-9.02 +- 0.28 extended wings and complex environment. However, even if this is a cluster, the spatial displacement of SN 2013dk means that its membership is not assured. The strongest statement we can make is that in the immediate environment of SN 2013dk (within 10 pc or so) we find no clear evidence of either a point source coincident with the SN or a young stellar cluster that could host a massive WR progenitor.

description: In this work, a parameter-efficient attention module is presented for emotion classification using a limited, or relatively small, number of electroencephalogram (EEG) signals. This module is called the Monotonicity Constrained Attention Module (MCAM) due to its capability of incorporating priors on the monotonicity when converting features' Gram matrices into attention matrices for better feature refinement. Our experiments have shown that MCAM's effectiveness is comparable to state-of-the-art attention modules in boosting the backbone network's performance in prediction while requiring less parameters. Several accompanying sensitivity analyses on trained models' prediction concerning different attacks are also performed. These attacks include various frequency domain filtering levels and gradually morphing between samples associated with multiple labels. Our results can help better understand different modules' behaviour in prediction and can provide guidance in applications where data is limited and are with noises.

Publisher: name: Zenodo

description: In today's ever-increasing competitive markets, particularly with the internet revolution and e-commerce mode of trading, brand perception plays a significant role in the consumer's selecting a preferred brand while making a purchase decision.

A brand is the face of the business and the products or services it offers. Brand identity is the visual component of a brand representing the core idea, the theme of the services/products it means. Brand perception refers to the customer's opinion of the Brand. It summarizes how customers feel about the Brand, including every direct or indirect experiencewith the Brand. Every Brand represents a promise and the core quality that the Brand fulfils as functional, experiential, or self-expressive benefits. Also, it is a promise that differentiates itself from its competitors' brands. The Brand Promise is fulfilled at every touchpoint of the Brand. Brand touchpoints are any point where a customer interacts with the Brand or its products orservices. It could be a simple telephone conversation, website look and feel, email communication, point of the purchase experience, interaction with marketing and sales personnel, or after-sales & service. Every interaction point reaffirms the brand promise, and any shortfall at any level can affect brand perception.

Brand Perception is built over time and managed by the Brand management process. It is built on a marketing foundation and focuses on how the Brand can constantly remain favourable to customers. Brand management is creating, managing, and improving a brand. It has become one of the most critical aspects of business strategy.

Brand management is an integral part of holistic marketing. It is a specific area of marketing that uses special techniques to increase a brand's perceived value. Branding and brand-based differentiation are powerful means for creating and sustaining a competitive advantage.

As one of the fundamental dimensions of brand equity, brand awareness is often considered a prerequisite of consumers' buying decisions, as it represents the main factor for including a brand in the consideration process. Brand awareness can also influence consumers' perceived risk assessment and confidence in purchasing decisions due to familiarity with the Brand and its characteristics.
Steering the optimization pathway in the control landscape using constraints

description: We show how additional constraints, restricting the spectrum of the optimized pulse or confining the system dynamics, can be used to steer optimization in quantum control towards distinct solutions. Our examples are multi-photon excitation in atoms and vibrational population transfer in molecules. We show that a spectral constraint is most effective in enforcing non-resonant two-photon absorption pathways in atoms and avoiding unnecessarily broad spectra in Raman transitions in molecules. While a constraint restricting the system to stay in an allowed subspace is also capable of identifying non-resonant excitation pathways, it does not avoid spurious peaks in the pulse spectrum. Both constraints are compatible with monotonic convergence but imply different additional numerical costs.

description: We present results on the radiation drag exerted by an isotropic and homogenous background of Lya photons on neutral gas clouds orbiting within HII regions around Population III stars of different masses. The Doppler shift causes a frequency difference between photons moving in the direction of the cloud and opposite to it resulting in a net momentum loss of the cloud in the direction of motion. We find that half of the angular momentum of gas with v_theta 10^8 yr even for low velocity clouds. Our results suggest that a sweet spot exists for the loss of angular momentum by radiation drag for gas clouds at z > 10 and with v ~ 20 km/s. Comparison to dynamical friction forces acting on typical gas clouds suggest that radiation drag is the dominant effect impacting the orbit. We propose that this effect can suppress the formation of extended gas discs in the first galaxies and help gas accretion near galactic centres and central black holes.

description: Planetary embryos are built through the collisional growth of 10-100 km sized objects called planetesimals, a formerly large population of objects, of which asteroids, comets and Kuiper-Belt objects represent the leftovers from planet formation in our solar system. Here, we follow the paradigm that turbulence created over-dense pebble clouds, which then collapse under their own self-gravity. We use the multi-physics code GIZMO to model the pebble cloud density as a continuum, with a polytropic equation of state to account for collisional interactions and capturing the phase transition to a quasi-incompressible solid object, i.e. a planetesimal in hydrostatic equilibrium. Thus we study cloud collapse effectively at the resolution of the forming planetesimals, allowing us to derive an initial mass function for planetesimals in relation to the total pebble mass of the collapsing cloud. The redistribution of angular momentum in the collapsing pebble cloud is the main mechanism leading to multiple fragmentation. The angular momentum of the pebble cloud and thus the centrifugal radius increases with distance to the sun, but the solid size of the forming planetesimals is constant. Therefore we find that with increasing distance to the sun, the number of forming planetesimals per pebble cloud increases. For all distances the formation of binaries occurs within higher hierarchical systems. The size distribution is top heavy and can be described with a Gaussian distribution of planetesimal mass. For the asteroid belt, we can infer a most likely size of 125 km, all stemming from pebble clouds of equivalent size 152 km.

description: Adding right-handed neutrino singlets and/or fermion triplets to the particle content of the Standard Model allows for the implementation of the seesaw mechanism to give mass to neutrinos and, simultaneously, for the construction of anomaly-free gauge group extensions of the theory. We consider Abelian extensions based on an extra U(1)_X gauge symmetry, where X is an arbitrary linear combination of the baryon number B and the individual lepton numbers L_{e,mu,tau}. By requiring cancellation of gauge anomalies, we perform a detailed analysis in order to identify the charge assignments under the new gauge symmetry that lead to neutrino phenomenology compatible with current experiments. In particular, we study how the new symmetry can constrain the flavor structure of the Majorana neutrino mass matrix, leading to two-zero textures with a minimal extra fermion and scalar content. The possibility of distinguishing different gauge symmetries and seesaw realizations at colliders is also briefly discussed.

description: We present a neural vocoder designed with low-powered Alternative and Augmentative Communication devices in mind. By combining elements of successful modern vocoders with established ideas from an older generation of technology, our system is able to produce high quality synthetic speech at 48kHz on devices where neural vocoders are otherwise prohibitively complex. The system is trained adversarially using differentiable pitch synchronous overlap add, and reduces complexity by relying on pitch synchronous Inverse Short-Time Fourier Transform (ISTFT) to generate speech samples. Our system achieves comparable quality with a strong (HiFi-GAN) baseline while using only a fraction of the compute. We present results of a perceptual evaluation as well as an analysis of system complexity.

description: Many applications in science call for the numerical simulation of systems on manifolds with spherical topology. Through use of integer spin weighted spherical harmonics we present a method which allows for the implementation of arbitrary tensorial evolution equations. Our method combines two numerical techniques that were originally developed with different applications in mind. The first is Huffenberger and Wandelt's spectral decomposition algorithm to perform the mapping from physical to spectral space. The second is the application of Luscombe and Luban's method, to convert numerically divergent linear recursions into stable nonlinear recursions, to the calculation of reduced Wigner d-functions. We give a detailed discussion of the theory and numerical implementation of our algorithm. The properties of our method are investigated by solving the scalar and vectorial advection equation on the sphere, as well as the 2+1 Maxwell equations on a deformed sphere.

Fertile Lands, Empty Hands: A Comparative Case Study on How Rural School Districts Addressed Food Insecurity During the 2020 COVID-19 Pandemic

description: Millions of students have engaged in virtual learning since the onset of the COVID-19 pandemic in the Spring of 2020. For rural food-insecure students who primarily access federally subsidized breakfast and lunch programs, learning from home means that school districts must strategically meet their needs, be it by food pickup site, food distribution program, or otherwise. Building on McLoughlin, et. al.’s 2020 seminal study, I consider the successes and challenges two rural school districts faced when strategizing to support their food-insecure students during the Spring and Summer of 2020, specifically asking: How have rural school districts affected by COVID-19 strategized to distribute meals to their food insecure students, and to what extent were their strategies effective in promoting equitable food access? Using geospatial and document analysis, as well as surveys and interviews with school staff members, I examine staff perception of their districts’ strategies, the logistics of food access in each district, and the equitability and accessibility of online promotional materials. I find that each school succeeded at: providing families and students participating in the program with a deep sense of community; providing somewhat accessible food pickup and delivery services to families; and utilizing promotional materials to advertise programming, all three of which amplified equity of access. Conversely, the districts faced challenges: navigating geographic span and a lack of transportation to food pickup sites; too short of time windows for easy food access; and a lack of promotion online about external partnerships. Based on my observations, I generate policy recommendations for rural school districts so that they might be better prepared to support food- insecure students the next time they cannot physically be in school.
title: “A grim and costly business” the mechanization, modernization, and decline of pulpwood logging in central Newfoundland

description: Between 1907 and 1927 the seasonal foray into the “lumberwoods” to harvest pulpwood for the Grand Falls and Corner Brook newsprint mills became an entrenched part of outport life in many Newfoundland communities. After World War Two, stabilized and growing markets for newsprint meant that thousands of rural Newfoundland men found work harvesting and delivering pulpwood. Beginning in the 1950s, mechanization and modernization dramatically reduced the labour requirements of Newfoundland’s pulpwood industry, creating a “corps of professional loggers” that constituted a fraction of the workers employed previously. In the 1950s, the Grand Falls mill’s importance to the province’s economy meant that few imagined that it would ever close. However, when the mill closure came in 2009 it did not have a catastrophic impact on the economy of central Newfoundland. This was due to a fifty-year decline in the economic importance of the pulp and paper, and pulpwood industry in Newfoundland. By 2009 more jobs had been lost in the preceding four decades than were lost by the complete closure of the mill. Had the closure of the mill occurred forty or fifty years previous, because of the dependence on the pulp and paper industry and the much larger number of jobs at stake, the region would have been economically devastated. The long-term impacts of mechanization and modernization meant that the deindustrialization of central Newfoundland was a slow process with an abrupt ending. For those loggers that remained after the mechanization efforts of the 1950s and 1960s, the process of mechanization did not stop, nor did the challenges faced in supplying the Grand Falls pulp and paper mill with wood. Using archival materials, company newsletters, local newspapers, and oral history, this thesis examines central Newfoundland’s loggers, the changing nature of their work, and how mechanization dramatically reduced their numbers ultimately diminishing the economic importance of the pulpwood harvest to the provincial economy.

Revealing Double White Dwarf Mergers with Multi-messenger Signals

description: A significant number of double white dwarfs (DWDs) are believed to merge within the Hubble time due to the gravitational wave (GW) emission during their inspiraling phase. The outcome of a DWD system is either a type Ia Supernova as the double-degenerate model, or a massive, long-lasting merger remnant. Expected multi-messenger signals of these events will help us to distinguish detailed merging physical processes. In this work, we aim to provide a generic scenario of DWD merging, investigate the emission of all major messengers, with a focus on GWs and neutrinos. Our goal is to provide some guidance for current and future (collaborative) efforts of multi-messenger observations. Throughout the merging evolution of a DWD system, different messengers (GW, neutrino and electromagnetic wave) will dominate at different times. In this work, we show that DWD merger events located at the distance of 1 kpc can indeed produce detectable signals of GWs and neutrinos. The GW frequency are in 0.3-0.6 Hz band around 10 days before tidal disruption begin. We estimate that in optimistic situations, the neutrino number detected by upcoming detectors such as JUNO and Hyper-Kamiokande can reach O(1) for a DWD merging event at $\sim$ 1 kpc.

Anisotropic power-law k-inflation

description: It is known that power-law k-inflation can be realized for the Lagrangian $P=Xg(Y)$, where $X=-(\partial ϕ)^2/2$ is the kinetic energy of a scalar field $ϕ$ and $g$ is an arbitrary function in terms of $Y=Xe^{λϕ/M_{pl}}$ ($λ$ is a constant and $M_{pl}$ is the reduced Planck mass). In the presence of a vector field coupled to the inflaton with an exponential coupling $f(ϕ) \propto e^{μϕ/M_{pl}}$, we show that the models with the Lagrangian $P=Xg(Y)$ generally give rise to anisotropic inflationary solutions with $Σ/H=constant$, where $Σ$ is an anisotropic shear and $H$ is an isotropic expansion rate. Provided these anisotropic solutions exist in the regime where the ratio $Σ/H$ is much smaller than 1, they are stable attractors irrespective of the forms of $g(Y)$. We apply our results to concrete models of k-inflation such as the generalized dilatonic ghost condensate/the DBI model and we numerically show that the solutions with different initial conditions converge to the anisotropic power-law inflationary attractors. Even in the de Sitter limit ($λ\to 0$) such solutions can exist, but in this case the null energy condition is generally violated. The latter property is consistent with the Wald's cosmic conjecture stating that the anisotropic hair does not survive on the de Sitter background in the presence of matter respecting the dominant/strong energy conditions.

On the Coherence of WMAP and Planck Temperature Maps

description: The recent data release of ESA's Planck mission together with earlier WMAP releases provide the first opportunity to compare high resolution full sky Cosmic Microwave Background temperature anisotropy maps. To quantify the coherence of these maps beyond the power spectrum we introduce Generalized Phases, unit vectors in the (2l+1) dimensional representation spaces. For a Gaussian distribution, Generalized Phases are random and if there is non-Gaussianity, they represent most of the non-Gaussian information. The alignment of these unit vectors from two maps can be characterized by their angle, 0 deg expected for full coherence, and 90 deg for random vectors. We analyze maps from both missions with the same mask and Nside=512 resolution, and compare both power spectra and Generalized Phases. We find excellent agreement of the Generalize Phases of Planck Smica map with that of the WMAP Q,V,W maps, rejecting the null hypothesis of no correlations at 5 sigma for l's l<700, l<900 and l<1100, respectively, except perhaps for l<10. Using foreground reduced maps for WMAP increases the phase coherence. The observed coherence angles can be explained with a simple assumption of Gaussianity and a WMAP noise model neglecting Planck noise, except for low-intermediate l's there is a slight, but significant off-set, depending on WMAP band. On the same scales WMAP power spectrum is about 2.6% higher at a very high significance, while at higher l's there appears to be no significant bias. Using our theoretical tools, we predict the phase alignment of Planck with a hypothetical perfect noiseless CMB experiment, finding decoherence at l > 2900; below this value Planck can be used most efficiently to constrain non-Gaussianity.
