description: Disaster exposure is a strong predictor of survivor mental health following large-scale disasters. However, there is continued debate regarding how disaster exposure should be measured and quantified, as well as whether specific types of disaster exposure are more likely to influence certain mental health outcomes like psychological distress or post-traumatic stress disorder (PTSD). In this article, we propose the Disaster Exposure Matrix to explain how specific types and levels of disaster exposure are associated with particular mental health outcomes. We use data from the Sandy Child and Family Health study—an observational cohort study of 1000 randomly selected New Jersey residents who were living in the nine counties most-affected by Hurricane Sandy (2012)—to examine how direct and indirect disaster exposure at both the individual and community levels influence the likelihood of experiencing psychological distress and probable PTSD in the two years after Hurricane Sandy. Weighted logistic regression models demonstrate that particular measures of individual-level direct and indirect exposure uniquely influence probable PTSD and psychological distress, respectively. Community-level indirect exposure is significantly associated with psychological distress but not with probable PTSD. Findings highlight the importance of specificity when measuring the effects of disaster exposure on mental health, including separating exposures that occur at the individual and community level, as well as distinguishing those that are experienced directly from the event from those that are indirect and experienced after the meteorological or geophysical event has passed.

description: We analyze the possibility to distinguish between quintessence and phantom scalar field models of dark energy using observations of luminosity distance moduli of SNe Ia, CMB anisotropies and polarization, matter density perturbations and baryon acoustic oscillations. Among the present observations only Planck data on CMB anisotropy and SDSS DR9 data on baryon acoustic oscillations may be able to decide between quintessence or phantom scalar field models, however for each model a set of best-fit parameters exists, which matches all data with similar goodness of fit. We compare the relative differences of best-fit model predictions with observational uncertainties for each type of data and we show that the accuracy of SNe Ia luminosity distance data is far from the one necessary to distinguish these types of dark energy models, while the CMB data (WMAP, ACT, SPT and especially Planck) are close to being able to reliably distinguish them. Also an improvement of the large-scale structure data (future releses of SDSS BOSS and e.g. Euclid or BigBOSS) will enable us to surely decide between quintessence and phantom dark energy.

title: Critical Democratic Education: A Case Study on Controversy Deliberation and Its Effects Among Pre-Service Elementary Teachers
Creators: name: Si, Shouqing
Publisher: name: Utah State University
Year: 2023

description: The state of democracy facing expanding political division and pervasive racial and social inequalities. Discussing and deliberating controversial social and political issues functions help foster students' civic contribution. I conducted a qualitative case study and recruited 14 participants, with whom I conducted interviews, self-reflection, observation, and autoethnography. I targeted the primary research question: How do pre-service elementary teachers experience and get influenced by discussing social and public issues? I broke it down to six operational questions:

What issues are considered controversial by pre-service teachers in their future social studies classrooms?
What challenges do pre-service teachers perceive in controversial issues teaching?
What are pre-service teachers' perceptions of their preparedness for teaching controversies from one to five (e.g., 1 = Not at all)?
How might deliberating controversial issues affect pre-service teachers' civic ideologies?
How might deliberating controversial issues affect their critical consciousness?
What approaches are viewed as the best ways to teach controversial issues?

I utilized a two-fold data analysis, in which I extrapolated individual-level initial codes and inferred common group-level themes. I finalized six sets of themes to answer the research questions accordingly. First, most participants presented inconsistency and confusion over defining controversy. Second, the participants reported five categories of challenges, including fear of retribution. Third, unpreparedness was pervasive due to four reasons such as lack of practice in the elementary classroom. Fourth, the deliberation of controversial issues was perceived to positively affect civic ideology in education. Fifth, I found that deliberation increase one's critical consciousness in five modes such as multiple perspectives and critical thinking skills. Sixth, most of the participants recommended take a stand and SAC (structured academic controversy) activities to address issues of controversy.
I expect its findings to meaningfully extend the scholarship on the discussion and deliberation of social and public issues in social studies teacher education programs. I hope to inspire colleagues to further explore this area of research and provide critical suggestions and ideas to better prepare prospective educators.

description: Single spins in the solid-state offer a unique opportunity to store and manipulate quantum information, and to perform quantum-enhanced sensing of local fields and charges. Optical control of these systems using techniques developed in atomic physics has yet to exploit all the advantages of the solid-state. We demonstrate voltage tunability of the spin energy levels in a single quantum dot by modifying how spins sense magnetic field. We find the in-plane g-factor varies discontinuously for electrons, as more holes are loaded onto the dot. In contrast, the in-plane hole g-factor varies continuously. The device can change the sign of the in-plane g-factor of a single hole, at which point an avoided crossing is observed in the two spin eigenstates. This is exactly what is required for universal control of a single spin with a single electrical gate.

description: In April of 2020, the National Center for Disaster Preparedness (NCDP) at Columbia University’s Earth Institute partnered with Commonwealth Edison (ComEd) to examine the coronavirus disease 2019 (COVID-19) pandemic and support relevant decision-making to facilitate workforce safety and continuity of utility operations in an environment where initial data were scant and variable. Due to the gradual and variable emergence of information during disasters, precise data is a luxury in decision-making. Instead, we must rely on a dynamic approach, which integrates new information as it becomes available. Often, this requires a combined subjective and objective decision-making framework that shifts toward objectivity as data variability converges and becomes more precise.

description: We investigate cosmological behavior in the quasi-Dilaton non-linear massive gravity. We perform a detailed dynamical analysis and examine the stable late-time solutions relevant to late time cosmic acceleration. We demonstrate that a dark-energy dominated, cosmological-constant-like solution is a late attractor of the dynamics. We also analyze the evolution of the universe at intermediate times, showing that the observed epoch sequence can be easily obtained in the model under consideration. Furthermore, we study the non-singular bounce and the cosmological turnaround which can be realized for a region of the parameter space. Last but not least, we use observational data from Type Ia Supernovae (SNIa), Baryon Acoustic Oscillations (BAO) and Cosmic Microwave Background (CMB), in order to constrain the parameters of the theory.

description: The evolution with carrier concentration of the electrical properties of amorphous indium oxide (InO) thin films has been studied using electronic double layer transistor configurations. Carrier variations of up to 7 X 10^(14) carriers/cm^2 were achieved using an ionic liquid as a gate dielectric. The superconductor-insulator transition was traversed and the magnitude and position of the large magnetoresistance peak found in the insulating regime were modified. The systematic variation of the magnetoresistance peak with charge concentration was found to be qualitatively consistent with a simulation based on a model involving granularity.

description: The proposed article develops a method of constructing mathematical models for displaying the dynamic States of technical objects in model problems of dynamics, in which heuristic approaches and the corresponding methodological base are implemented. The aim of the article is to develop a detailed technology for constructing mathematical models of interaction of elements of a mechanical oscillatory system with not-holding ties. The features of dynamic interactions of a chain structure with three degrees of freedom are studied from the standpoint of assessing the possibilities of forming asymmetry of the parameters of the dynamic state of the elements in the formation of dynamic reactions of bonds under the action of single and joint acting forces.

description: This is the Part I paper of our series of full papers on a gauge-invariant {\it linear} perturbation theory on the Schwarzschild background spacetime which was briefly reported in our short papers [K.~Nakamura, Class. Quantum Grav. {\bf 38} (2021), 145010; K.~Nakamura, Letters in High Energy Physics {\bf 2021} (2021), 215.]. We first review our general framework of the gauge-invariant perturbation theory, which can be easily extended to the {\it higher-order} perturbation theory. When we apply this general framework to perturbations on the Schwarzschild background spacetime, a gauge-invariant treatments of $l=0,1$ mode perturbations are required. On the other hand, in the current consensus on the perturbations of the Schwarzschild spacetime, gauge-invariant treatments for $l=0,1$ modes are difficult if we keep the reconstruction of the original metric perturbations in our mind. Based on this situation, we propose a strategy of a gauge-invariant treatments of $l=0,1$ mode perturbations through the decomposition of the metric perturbations by singular harmonic functions at once and the regularization of this singularity through the imposition of the boundary conditions to the Einstein equations. Following this proposal, we derive the linearized Einstein equations for any modes of $l\geq 0$ in a gauge-invariant manner. We discuss the solutions to the odd-mode perturbation equations in the linearized Einstein equations and show that these perturbations include the Kerr parameter perturbation in these odd-mode perturbation, which is physically reasonable.

description: We continue the study of the theory of scattering for some long range Hartree equations with potential |x|^-gamma, performed in a previous paper, denoted as I, in the range 1/2 < gamma < 1. Here we extend the results to the range 1/3 < gamma < 1/2. More precisely, we study the local Cauchy problem with infinite initial time, which is the main step in the construction of the modified wave operators. We solve that problem without loss of regularity between the asymptotic state and the solution, as in I, but in contrast to I, we are no longer able to cover the entire subcritical range of regularity of the solutions. The method is an extension of that of I, using a better asymptotic form of the solutions, obtained as the next step of a natural procedure of successive approximations.

description: This is the Part II paper of our series of papers on a gauge-invariant perturbation theory on the Schwarzschild background spacetime.

We discuss the strategy to solve the linearized Einstein equations for these even-mode perturbations including $l=0,1$ modes. Furthermore, we explicitly derive the $l=0,1$ mode solutions to the linearized Einstein equations in both the vacuum and the non-vacuum cases. We show that the solutions for $l=0$ mode perturbations includes the additional Schwarzschild mass parameter perturbation, which is physically reasonable. Then, we conclude that our proposal of the resolution of the $l=0,1$-mode problem is physically reasonable due to the realization of the additional Schwarzschild mass parameter perturbation and the Kerr parameter perturbation in the Part I paper.

After reviewing our general framework of the gauge-invariant perturbation theory and the proposal on the gauge-invariant treatments for $l=0,1$ mode perturbations on the Schwarzschild background spacetime in [K.~Nakamura, arXiv:2110.13508 [gr-qc]], we examine the problem whether the $l=0,1$ even-mode solutions derived in the Part II paper [K.~Nakamura, arXiv:2110.13512 [gr-qc]] are physically reasonable, or not. We consider the linearized versions of the Lemaître-Tolman-Bondi solution and the non-rotating C-metric. As the result, we show that our derived even-mode solutions to the linearized Einstein equations actually realize above two linearized solutions. This fact supports that our derived solutions are physically reasonable, which implies that our proposal on the gauge-invariant treatments for $l=0,1$ mode perturbations are also physically reasonable. We also briefly summarize our conclusions of our series of papers.

Cataloging

description: Part of the life cycle of scholarly communications is discovery, and one type of material often obscured by the federated results of library search interfaces is open access materials not hosted in the institutional repository but living on the open web. Selecting and cataloging such open access resources builds a focused collection of open access materials that appear in the same search results as materials that libraries lease, purchase, and host. Bringing open access materials into catalog results makes them easier to discover, use, and cite. Identifying and cataloging open access resources emphasizes the vital roles of collection development and cataloging in curating collections of open access resources for research. As with proprietary collection building, a commitment to create catalog records for the open access scholarship created by your faculty, students, and staff improves the discoverability of these resources and can bring your institutional affiliates into new scholarly citation networks. This process also offers an opportunity for modeling critical cataloging. Using local headings and affirming keywords and vocabulary to build a full catalog record improves the catalog’s affirmation of people of historically marginalized identities and asserts the critical value of ethical naming as a scholarly communications practice to support distribution and future authorship. We share here the steps for creating or a conversation for affirming and continuing this practice at your institution.

description: With gratitude for the space-making oxygen she generates for so many as a blooming evergreen, for the tender care with which she as a gardener waters and prunes all her plants, including me, I offer this clinical essay for this festschrift in honor of my beloved advisor and doktormutter, Ann Belford Ulanov. Ann’s focus on applied or depth theology as an “eschatology of presence,” which fosters the God-given integrity and freedom of the person in relation to the divine, sets apart her writing and teaching. Depth theology is “faith” in the psyche, which in turn is “part of the flesh in which the Holy incarnates,” and, as she demonstrates, opens onto faith in God as experienced through the psyche, conscious and unconscious. For theology and psychology today, Ulanov’s work, which employs a “rigor of the heart” that demands heart, soul, strength and mind work together as advised in the shema, opens new vistas to receiving all of ourselves and others, and like Mary, to receiving God among us in the flesh.

description: Scalar-tensor theories are a compelling alternative to general relativity and one of the most accepted extensions of Einstein's theory. Black holes in these theories have no hair, but could grow "wigs" supported by time-dependent boundary conditions or spatial gradients. Time-dependent or spatially varying fields lead in general to nontrivial black hole dynamics, with potentially interesting experimental consequences. We carry out a numerical investigation of the dynamics of single and binary black holes in the presence of scalar fields. In particular we study gravitational and scalar radiation from black-hole binaries in a constant scalar-field gradient, and we compare our numerical findings to analytical models. In the single black hole case we find that, after a short transient, the scalar field relaxes to static configurations, in agreement with perturbative calculations. Furthermore we predict analytically (and verify numerically) that accelerated black holes in a scalar-field gradient emit scalar radiation. For a quasicircular black-hole binary, our analytical and numerical calculations show that the dominant component of the scalar radiation is emitted at twice the binary's orbital frequency.

description: In multiview applications, multiple cameras acquire the same scene from different viewpoints and generally produce correlated video streams. This results in large amounts of highly redundant data. In order to save resources, it is critical to handle properly this correlation during encoding and transmission of the multiview data. In this work, we propose a correlation-aware packet scheduling algorithm for multi-camera networks, where information from all cameras are transmitted over a bottleneck channel to clients that reconstruct the multiview images. The scheduling algorithm relies on a new rate-distortion model that captures the importance of each view in the scene reconstruction. We propose a problem formulation for the optimization of the packet scheduling policies, which adapt to variations in the scene content. Then, we design a low complexity scheduling algorithm based on a trellis search that selects the subset of candidate packets to be transmitted towards effective multiview reconstruction at clients. Extensive simulation results confirm the gain of our scheduling algorithm when inter-source correlation information is used in the scheduler, compared to scheduling policies with no information about the correlation or non-adaptive scheduling policies. We finally show that increasing the optimization horizon in the packet scheduling algorithm improves the transmission performance, especially in scenarios where the level of correlation rapidly varies with time.

description: We extend our recent derivation of the time evolution equations for the energy content of magnetic fields and turbulent motions for incompressible, homogeneous, and isotropic turbulence to include the case of nonvanishing helicity. These equations are subsequently numerically integrated in order to predict the present day primordial magnetic field strength and correlation length, depending on its initial helicity and magnetic energy density. We find that all prior analytic predictions for helical magnetic fields, such as the epoch when they become maximally helical and their subsequent growth of correlation length L ~ a^{1/3} and decrease of magnetic field strength B ~ a^{-1/3} with scale factor a, are well confirmed by the simulations. An initially fully helical primordial magnetic field is a factor 4 10^4 stronger at the present epoch then its nonhelical counterpart when generated during the electroweak epoch.

Statistical Entropy of a BTZ Black Hole from Loop Quantum Gravity

description: We compute the statistical entropy of a BTZ black hole in the context of three-dimensional Euclidean loop quantum gravity with a cosmological constant $Λ$. As in the four-dimensional case, a quantum state of the black hole is characterized by a spin network state. Now however, the underlying colored graph $Γ$ lives in a two-dimensional spacelike surface $Σ$, and some of its links cross the black hole horizon, which is viewed as a circular boundary of $Σ$. Each link $\ell$ crossing the horizon is colored by a spin $j_\ell$ (at the kinematical level), and the length $L$ of the horizon is given by the sum $L=\sum_\ell L_\ell$ of the fundamental length contributions $L_\ell$ carried by the spins $j_\ell$ of the links $\ell$. We propose an estimation for the number $N^\text{BTZ}_Γ(L,Λ)$ of the Euclidean BTZ black hole microstates (defined on a fixed graph $Γ$) based on an analytic continuation from the case $Λ>0$ to the case $Λ<0$. In our model, we show that $N^\text{BTZ}_Γ(L,Λ)$ reproduces the Bekenstein-Hawking entropy in the classical limit. This asymptotic behavior is independent of the choice of the graph $Γ$ provided that the condition $L=\sum_\ell L_\ell$ is satisfied, as it should be in three-dimensional quantum gravity.

Topology optimization of robust superhydrophobic surfaces

description: In this paper we apply topology optimization to micro-structured superhydrophobic surfaces for the first time. It has been experimentally observed that a droplet suspended on a brush of micrometric posts shows a high static contact angle and low roll-off angle. To keep the fluid from penetrating the space between the posts, we search for an optimal post cross section, that minimizes the vertical displacement of the liquid-air interface at the base of the drop when a pressure difference is applied. Topology optimisation proves effective in this framework, showing that posts with a branching cross-section are optimal, which is consistent with several biologic strategies to achieve superhydrophobicity. Through a filtering technique, we can also control the characteristic length scale of the optimal design, thus obtaining feasible geometries

Large Platonic Markets with Delays

description: The objective is to develop a general stochastic approach to delays on financial markets. We suggest such a concept in the context of large platonic markets, which allow infinitely many assets and incorporate a restricted information setting. The discussion is divided into information delays and order execution delays. The former enables modelling of markets where the observed information is delayed, while the latter provides the opportunity to defer the indexed time of a received asset price. Both delays may be designed randomly and inhomogeneously over time. We show that delayed markets are equipped with a fundamental theorem of asset pricing and our main result is inheritance of the no asymptotic Lp-free lunch condition under both delay types. Eventually, we suggest an approach to verify absence of Lp-free lunch on markets with multiple brokers endowed with deviating trading speeds.

Long time decay and asymptotics for the complex mKdV equation

description: We study the asymptotics of the complex modified Korteweg-de Vries equation $\partial_t u + \partial_x^3 u = -|u|^2 \partial_x u$, which can be used to model vortex filament dynamics. In the real-valued case, it is known that solutions with small, localized initial data exhibit modified scattering for $|x| \geq t^{1/3}$ and behave self-similarly for $|x| \leq t^{1/3}$. We prove that the same asymptotics hold for complex mKdV. The major difficulty in the complex case is that the nonlinearity cannot be expressed as a derivative, which makes the low-frequency dynamics harder to control. To overcome this difficulty, we introduce the decomposition $u = S + w$, where $S$ is a self-similar solution with the same mean as $u$ and $w$ is a remainder that has better decay. By using the explicit expression for $S$, we are able to get better low-frequency behavior for $u$ than we could from dispersive estimates alone. An advantage of our method is its robustness: It does not depend on the precise algebraic structure of the equation, and as such can be more readily adapted to other contexts.

Aging Logarithmic Galilean Field Theories

description: We analytically compute correlation and response functions of scalar operators for the systems with Galilean and corresponding aging symmetries for general spatial dimensions $d$ and dynamical exponent $z$, along with their logarithmic and logarithmic squared extensions, using the gauge/gravity duality. These non-conformal extensions of the aging geometry are marked by two dimensionful parameters, eigenvalue $\mathcal M$ of an internal coordinate and aging parameter $α$. We further perform systematic investigations on two-time response functions for general $d$ and $z$, and identify the growth exponent as a function of the scaling dimensions $Δ$ of the dual field theory operators and aging parameter $α$ in our theory. The initial growth exponent is only controlled by $Δ$, while its late time behavior by $α$ as well as $Δ$. These behaviors are separated by a time scale order of the waiting time. We attempt to make contact our results with some field theoretical growth models, such as Kim-Kosterlitz model at higher number of spatial dimensions $d$.

Dynamic phase diagrams of the Blume-Capel model in an oscillating field by the path probability method

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We calculate the dynamic phase transition (DPT) temperatures and present the dynamic phase diagrams in the Blume-Capel model under the presence of a time-dependent oscillating external magnetic field by using the path probability method. We study the time variation of the average order parameters to obtain the phases in the system and the paramagnetic (P), ferromagnetic (F) and the F + P mixed phases are found. We also investigate the thermal behavior of the dynamic order parameters to analyze the nature (continuous and discontinuous) of transitions and to obtain the DPT points. We present the dynamic phase diagrams in three planes, namely (T, h), (d, T) and (k2/k1, T), where T is the reduced temperature, h the reduced magnetic field amplitude, d the reduced crystal-field interaction and the k2, k1 rate constants. The phase diagrams exhibit dynamic tricritical and reentrant behaviors as well as a double critical end point and triple point, strongly depending on the values of the interaction parameters and the rate constants. We compare and discuss the dynamic phase diagrams with dynamic phase diagrams that are obtained within the Glauber-type stochastic dynamics based on the mean-field theory and the effective field theory.

description: We use deep far-infrared data from the PEP/GOODS-Herschel surveys and rest frame ultraviolet photometry to study the evolution of the molecular gas mass function of normal star forming galaxies. Computing the molecular gas mass, M(mol), by scaling star formation rates (SFR) through depletion timescales, or combining IR luminosity and obscuration properties as in Nordon et al., we obtain M(mol) for roughly 700, z=0.2-3.0 galaxies near the star forming "main sequence". The number density of galaxies follows a Schechter function of M(mol). The characteristic mass M* is found to strongly evolve up to z~1, and then to flatten at earlier epochs, resembling the infrared luminosity evolution of similar objects. At z~1, our result is supported by an estimate based on the stellar mass function of star forming galaxies and gas fraction scalings from the PHIBSS survey. We compare our measurements to results from current models, finding better agreement with those that are treating star formation laws directly rather than in post-processing. Integrating the mass function, we study the evolution of the M(mol) density and its density parameter Omega(mol).

Robustness of spin filtering against current leakage in a Rashba-Dresselhaus-Aharonov-Bohm interferometer

description: In an earlier paper [Phys. Rev. B 84, 035323 (2011)], we proposed a spin filter which was based on a diamond-like interferometer, subject to both an Aharonov-Bohm flux and (Rashba and Dresselhaus) spin-orbit interactions. Here we show that the full polarization of the outgoing electron spins remains the same even when one allows leakage of electrons from the branches of the interferometer. Once the gate voltage on one of the branches is tuned to achieve an effective symmetry between them, this polarization can be controlled by the electric and/or magnetic fields which determine the spin-orbit interaction strength and the Aharonov-Bohm flux.

description: We present a new supersymmetric AdS_6 solution of type IIB supergravity with SU(2) isometry. Through the AdS/CFT correspondence, this has potentially very interesting implications for 5d fixed point theories. This solution is the result of a non-Abelian T-duality on the known supersymmetric AdS_6 solution of massive IIA. The SU(2) R-symmetry is untouched, leading to sixteen supercharges and preserved supersymmetry.
