description: Developing an accurate simulation method for the electrochemical stability of solids, as well as understanding the physics related with its accuracy, is critically important for improving the performance of compounds and predicting the stability of new materials in aqueous environments. Herein we propose a workflow for the accurate calculation of first-principles electrochemical phase (Pourbaix) diagrams. With this scheme, we study the electrochemical stabilities of Ti and Ti oxides using density-functional theory. First, we find the accuracy of an exchange-correlation functional in predicting formation energies and electrochemical stabilities is closely related with the electronic exchange interaction therein. Second, the metaGGA and hybrid functionals with a more precise description of the electronic exchange interaction lead to a systematic improvement in the accuracy of the Pourbaix diagrams. Furthermore, we show that accurate Ti Pourbaix diagrams also require that thermal effects are included through vibrational contributions to the free energy. We then use these diagrams to explain various experimental electrochemical phenomena for the Ti--O system, and show that if experimental formation energies for Ti oxides, which contain contributions from defects owing to their generation at high (combustion) temperatures, are directly used to predict room temperature Pourbaix diagrams then significant inaccuracies result. In contrast, the formation energies from accurate first-principles calculations, e.g., using metaGGA and hybrid functionals, are found to be more reliable. Finally to facilitate the future application of our accurate electrochemical phase equilibria diagrams, the variation of the Ti Pourbaix diagrams with aqueous ion concentration is also provided.

3-Dimensional Observations and a Simple Model of the Atmospheric Internal Boundary Layer that formed during a Summertime Oregon Upwelling Event
Creators: name: Monbureau, Elaine M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Oceanic and atmospheric processes associated with the Oregon coastal upwelling system were observed during the multi-institutional COAST (Coastal Ocean Advances in Shelf Transport) research program. After several days of upwelling-favorable wind-stress, air temperature data collected by aircraft during COAST showed a pocket of cool air over the cold coastal water and within the marine atmospheric boundary layer (MABL). This pocket of cool air was an internal boundary layer (IBL) that formed through sensible heat flux form the air into the ocean as warmer air was advected over the cooler, upwelled water. Presented in this paper are comprehensive views of the IBL created from the following COAST data products: (1) atmospheric data acquired by aircraft, (2) subsurface ocean temperature and near surface air temperature acquired by 6 moorings, and (3) subsurface ocean temperature measured by Aircraft-deployed eXpendable Bathy Thermographs (AXBTs). A simple analytical model, created from the 3-D advection-diffusion equation and using parameters set by the observational data, is used to visualize the near-surface air temperature structure, where no observational data exists, and to estimate the contribution of thermal wind-shear and enhanced stability on the wind field.

description: Planck data towards the galaxy M82 are analyzed in the 70, 100 and 143 GHz bands. A substantial north-south and East-West temperature asymmetry is found, extending up to 1 degree from the galactic center. Being almost frequency-independent, these temperature asymmetries are indicative of a Doppler-induced effect regarding the line-of-sight dynamics on the halo scale, the ejections from the galactic center and, possibly, even the tidal interaction with M81 galaxy. The temperature asymmetry thus acts as a model-independent tool to reveal the bulk dynamics in nearby edge-on spiral galaxies, like the Sunyaev-Zeldovich effect for clusters of galaxies.

The results agree with the well-known formulae in the zero vorticity case,but they incorporate the effects of vorticity through solutions to the Rayleigh equation. We extend the results to permit continuous density stratification and to internal waves between two constant-density fluids. Several examples are discussed.

Perceptions of Free Will and Self-Control in a Medically Relevant Treatment Recommendation Scenario
Creators: name: Alderson, Courtney
Publisher: name: Open Science Framework
Year: 2022
Subjects: subject: Social and Behavioral Sciences

description: Abstract: Do provider perceptions of patient free will and self-control influence treatment recommendations and do such perceptions differ due to race? If so, such bias may be a mechanism for racial disparities in medical treatment recommendations. We hypothesized: (1) greater perceived patient free will would indirectly affect treatment recommendations for patients through increased perceived patient self-control; (2) participants would perceive greater free will for a hypothetical racial ingroup patient than outgroup patient; and (3) such effect would be exacerbated by greater levels of racial identity and racial bias. A 2 (Participant: Black vs. White) x 2 (Target: Black vs. White) x Continuous (Racial Identity/Racial Bias) between-subjects design supported hypothesis 1. Perceived patient free will predicted more rigorous treatment recommendations. No evidence was found in support of hypotheses 2 and 3. Using a novel experimental design, this work demonstrates the importance of free will and self-control perceptions.

We prove that a set of frequencies in ${\mathbb Z}^d$ satisfies the strict majorant property on $L^p([0,1]^d)$ for all $p> 0$ if and only if the set is affinely independent. We further construct three types of violations of the strict majorant property. Any set of at least $d+2$ frequencies in ${\mathbb Z}^d$ violates the strict majorant property on $L^p([0,1]^d)$ for an open interval of $p \not\in 2 {\mathbb N}$ of length 2. Any infinite set of frequencies in ${\mathbb Z}^d$ violates the strict majorant property on $L^p([0,1]^d)$ for an infinite sequence of open intervals of $p \not\in 2 {\mathbb N}$ of length $2$. Finally, given any $p>0$ with $p \not\in 2{\mathbb N}$, we exhibit a set of $d+2$ frequencies on the moment curve in ${\mathbb R}^d$ that violate the strict majorant property on $L^p([0,1]^d).$

PRACTITIONER PERSPECTIVES AND PEDAGOGIES IN GLOBALLY-MINDED WORLD LANGUAGE EDUCATORS

description: ABSTRACT
      Meghan Jones Degler: Practitioner Perspectives and Pedagogies in Globally-Minded World Language Educators
      (Under the direction of Jocelyn Glazier)
      Over the previous few decades, global education has become a buzzword among education researchers and practitioners mindful of the realities of a globalizing society. In these years, the field has grown to include multiple definitions and ideologies. Neoliberal ideals reflect the development of knowledge and skills for individual and corporate gain, centrist perspectives acknowledge an appreciation, awareness, and openness toward other cultures and perspectives, and liberal philosophies evidence a dedication to action and interaction in the name of social transformation. World language education literature possesses a similar ideological continuum that juxtaposes language learning for individual gain, developing awareness of cultural others, and using language skills to cross borders culturally and linguistically. To date, however, there are no empirical studies that connect these two ideologically similar fields. This project uses a collective case study design to explore the perspectives and accompanying practices of five globally-minded world language teachers who seek to incorporate global frameworks into world language instruction. Deductive coding connects teacher perspectives and practices with the existing theoretical and empirical literature on both global education and world language education. Findings in each case illustrate diverse teacher backgrounds with unique approaches to incorporating global frameworks into world language classes. Across cases, findings show a wide range of perspectives and practices, highlighting the multifaceted nature of the ideas that surround
      iv
      both fields. Implications of this study show a need for educational opportunities that help teachers connect their personal experience to their ideologies, make space for global experiences that contribute to content knowledge and teaching resources, and advocate educational policies that prioritize the incorporation of global frameworks into world language content. While the findings of this study are unique and context-dependent, they suggest that there is space in the scholarly conversation to include discussions of how world language education complements the broader goals of global education in both theory and practice.

description: We investigate the exclusive rare semileptonic decays $ B_c \to D_{s}^{(*)}\,(\ell \ell, ν\barν)$ induced by neutral current transition $b \to s (\ell \ell,ν\barν)$ in the presence of non-universal $Z^{\prime}$, scalar and vector leptoquark new physics models. We constrain the new physics parameter space by using the latest experimental measurements of $R_{K^{(*)}}$, $P_5^{\prime}$, $\mathcal{B}(B_s \to ϕμ^+ μ^-)$ and $\mathcal{B}(B_s \to μ^+ μ^-)$. Throughout the analysis, we choose to work with the particular new physics scenario $C_9 ^{μμ}(NP)=-C_{10} ^{μμ}(NP)$ where both $Z^{\prime}$, $S_{1/3}^3$ and $U_{-2/3}^3$ leptoquarks satisfy the condition. Using these new coupling parameters we scrutinize the several physical observables such as differential branching fraction, the forward backward asymmetry, the lepton polarization asymmetry, the angular observable $P^{\prime}_5$ and the lepton flavor universal sensitive observables including the ratio of branching ratio $R_{D_s^{(*)}}$ and the few $Q$ parameters in the $B_c \to D_s^{(*)}\,μ^+ μ^-$ and $B_c \to D_s^{(*)}\, ν\barν$ decay processes.

User Tampering in Reinforcement Learning Recommender Systems

Publisher: name: arXiv
Year: 2021
Subjects: subject: Artificial Intelligence (cs.AI)
subject: FOS: Computer and information sciences

description: In this paper, we introduce new formal methods and provide empirical evidence to highlight a unique safety concern prevalent in reinforcement learning (RL)-based recommendation algorithms -- 'user tampering.' User tampering is a situation where an RL-based recommender system may manipulate a media user's opinions through its suggestions as part of a policy to maximize long-term user engagement. We use formal techniques from causal modeling to critically analyze prevailing solutions proposed in the literature for implementing scalable RL-based recommendation systems, and we observe that these methods do not adequately prevent user tampering. Moreover, we evaluate existing mitigation strategies for reward tampering issues, and show that these methods are insufficient in addressing the distinct phenomenon of user tampering within the context of recommendations. We further reinforce our findings with a simulation study of an RL-based recommendation system focused on the dissemination of political content. Our study shows that a Q-learning algorithm consistently learns to exploit its opportunities to polarize simulated users with its early recommendations in order to have more consistent success with subsequent recommendations that align with this induced polarization. Our findings emphasize the necessity for developing safer RL-based recommendation systems and suggest that achieving such safety would require a fundamental shift in the design away from the approaches we have seen in the recent literature.

Tritium beta decay with modified neutrino dispersion relations: KATRIN in the dark sea

Publisher: name: arXiv
Year: 2021

subject: FOS: Physical sciences

description: We explore beta decays in a dark background field, which could be formed by dark matter, dark energy or a fifth force potential. In such scenarios, the neutrino's dispersion relation will be modified by its collective interaction with the dark field, which can have interesting consequences in experiments using tritium beta decays to determine the absolute neutrino mass. Among the most general interaction forms, the (pseudo)scalar and (axial-)vector ones are found to have interesting effects on the spectrum of beta decays. In particular, the vector and axial-vector potentials can induce distinct signatures by shifting the overall electron energy scale, possibly beyond the usually defined endpoint. The scalar and pseudoscalar potentials are able to mimic a neutrino mass beyond the cosmological bounds. We have placed stringent constraints on the dark potentials based on the available experimental data of KATRIN. The sensitivity of future KATRIN runs is also discussed.

description: We develop tools for the efficient evaluation of Wilson lines in 3D higher spin gravity, and use these to compute entanglement entropy in the hs$[λ]$ Vasiliev theory that governs the bulk side of the duality proposal of Gaberdiel and Gopakumar. Our main technical advance is the determination of SL(N) Wilson lines for arbitrary $N$, which, in suitable cases, enables us to analytically continue to hs$[λ]$ via $N \rightarrow -λ$. We apply this result to compute various quantities of interest, including entanglement entropy expanded perturbatively in the background higher spin charge, chemical potential, and interval size. This includes a computation of entanglement entropy in the higher spin black hole of the Vasiliev theory. These results are consistent with conformal field theory calculations. We also provide an alternative derivation of the Wilson line, by showing how it arises naturally from earlier work on scalar correlators in higher spin theory. The general picture that emerges is consistent with the statement that the SL(N) Wilson line computes the semiclassical $W_N$ vacuum block, and our results provide an explicit result for this object.

description: Based on symmetry consideration of migration and shape deformations, we formulate phenomenologically the dynamics of cell crawling in two dimensions. Forces are introduced to change the cell shape. The shape deformations induce migration of the cell on a substrate. For time-independent forces we show that not only a stationary motion but also a limit cycle oscillation of the migration velocity and the shape occurs as a result of nonlinear coupling between different deformation modes. Time-dependent forces are generated in a stochastic manner by utilizing the so-called coherence resonance of an excitable system. The present coarse-grained model has a flexibility that it can be applied, e.g., both to keratocyte cells and to Dictyostelium cells, which exhibit quite different dynamics from each other. The key factors for the motile behavior inherent in each cell type are identified in our model.

Tourist behaviour and visitor experience

description: The growth of luxury tourism has been brought to a grinding halt due to the COVID-19 pandemic affecting most parts of the world since early 2020. Although the time for recovery of hospitality and tourism industries is still unclear, experience from the SARS outbreak in 2003 showed that the bounce back from consumers could be fast. The group of most affluent consumers, mostly known as HNWIs (high net worth individuals), will resume their original consumption behaviour much sooner than the rest of the market; these affluent consumers are the main target market of luxury hospitality and tourism industries. This chapter presents different types of luxury tourism, luxury lifestyle, luxury tourists' decision-making and luxury hospitality products. The luxury food and beverage business in Singapore is presented to illustrate the commercial environment during the pandemic.

description: We consider, computationally and experimentally, the scaling properties of force networks in the systems of circular particles exposed to compression in two spatial dimensions. The simulations consider polydisperse and monodisperse particles, both frictional and frictionless, and in experiments we use monodisperse and bidisperse particles. While for some of the considered systems we observe consistent scaling exponents describing the behavior of the force networks, we find that this behavior is it not universal. In particular, monodisperse frictionless systems that partially crystallize under compression, show scaling properties that are significantly different compared to the other considered systems. The findings of non-universality are confirmed by explicitly computing fractal dimension for the considered systems. The results of physical experiments are consistent with the results obtained in simulations of frictional particles.

description: It is well known that qubits immersed in a squeezed vacuum environment exhibit many exotic phenomena, including dissipative entanglement stabilization. Here, we show that these effects only require interference between excitation and decay processes, and can be faithfully mimicked without non-classical light using simple classical temporal modulation. We present schemes that harnesses this idea to stabilize entanglement between two remote qubits coupled via a transmission line or waveguide, where either the qubit-waveguide coupling is modulated, or the qubits are directly driven. We analyze the resilience of these approaches against various imperfections, and also characterize the trade-off between the speed and quality of entanglement stabilization. Our protocols are compatible with state of the art cavity QED systems.

description: The pioneering experiments of linear spectroscopy were performed using flames in the 1800s, but nonlinear optical measurements had to wait until lasers became available in the twentieth century. Because the nonlinear cross section of materials is very small, usually macroscopic bulk samples and pulsed lasers are used. Numerous efforts have explored coherent nonlinear signal generation from individual nanoparticles or small atomic ensembles with millions of atoms. Experiments on a single semiconductor quantum dot have also been reported, albeit with a very small yield. Here, we report on coherent nonlinear spectroscopy of a single molecule under continuous-wave single-pass illumination, where efficient photon-molecule coupling in a tight focus allows switching of a laser beam by less than a handful of pump photons nearly resonant with the sharp molecular transition. Aside from their fundamental importance, our results emphasize the potential of organic molecules for applications such as quantum information processing, which require strong nonlinearities.

Subjects: subject: 610 Medical sciences Medicine

description: Um die Auswirkungen einer Ausdauerselektion sowie eines Ausdauertrainings auf das muskuläre Transkriptomprofil darzustellen, wurde ein Mauskollektiv einer auf Ausdauer selektierten Mauslinie sowie einer Kontrolllinie betrachtet. Im Zuge der Ausdauerselektion wird die muskuläre Energieversorgung verbessert. Darüber hinaus erhöht sich die muskuläre oxidative Stressresistenz. Trainingsbedingte transkriptionelle Anpassungsvorgänge erfolgen durch eine Stimulation muskulärer Reparaturmechanismen, verdeutlicht durch eine erhöhte Expression Myogenese regulierender Faktoren.

description: Ziel der Arbeit war die Betrachtung von Genexpressionsunterschieden, die ein Laufbandtraining auf transkriptioneller Ebene in der Hypophyse von Mäusen bewirkt. Es wurde untersucht, ob eine Langzeitselektion nach hoher Laufleistung zu ähnlichen Expressionsunterschieden im Transkriptom führt wie ein dreiwöchiges Laufbandtraining bei nicht-selektierten Kontrollen.
Shitting medals: L.I. Brezhnev, the Great Patriotic War, and the failure of the personality cult, 1965-1982
Creators: name: Nolan, Adrianne
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: This thesis explores the relationship between L.I. Brezhnev's cult of personality and the memory of the Second World War in the Soviet Union. By glorifying and falsifying Brezhnev's record of wartime service, his personality cult placed him within the myth of the Great Patriotic War, which had become the historical anchor of Soviet regime legitimacy. The General Secretary also used the memory of the war to bolster his other public personae, or hero roles. Brezhnev's war hero image, however, ultimately contributed to the failure of his personality cult. Becoming increasingly overblown, this persona invited ridicule that undermined Brezhnev's cult. The consequences of this failure, moreover, potentially reach beyond the 1970s and 1980s. The implosion of Brezhnev's cult undermined not only his legitimacy but, by encouraging the desacralization of the leadership, may also have gravely damaged the legitimacy of the Soviet regime as a whole.

description: Ultrafast laser pump-probe spectroscopy is an important and growing field of physical chemistry that allows the measurement of chemical dynamics on their natural timescales, but undergraduate laboratory courses lack examples of such spectroscopy and the interpretation of the dynamics that occur. Here we develop and implement an ultrafast pump probe spectroscopy experiment for the undergraduate physical chemistry laboratory course at the University of California Berkeley. The goal of the experiment is to expose students to concepts in solid-state chemistry and ultrafast spectroscopy via classic coherent phonon dynamics principles developed by researchers over multiple decades. The experiment utilizes a modern high-repetition-rate 800 nm femtosecond Ti:Sapphire laser, split pulses with a variable time delay, and sensitive detection of transient reflectivity signals using the lock-in technique. The experiment involves minimal intervention from students and is therefore easy and safe to implement in the laboratory. Students first perform an intensity autocorrelation measurement on the femtosecond laser pulses to obtain their temporal duration. Then, students measure the pump-probe reflectivity of a single-crystal antimony sample to determine the period of coherent phonon oscillations initiated by an ultrafast pulse excitation, which is analyzed by fitting to a sine wave. Students who completed the experiment in-person obtained good experimental results, and students who took the course remotely due to the COVID-19 pandemic were provided with the data they would have obtained during the experiment to analyze. Evaluation of student written and oral reports reveals that the learning goals were met, and that students gained an appreciation for the field of ultrafast laser-induced chemistry.

description: It is sometimes argued that the uneven sky coverage of the Sloan Digital Sky Survey (SDSS) biases the distribution of satellite galaxies discovered by it to align with the polar plane defined by the 11 brighter, classical Milky Way (MW) satellites. This might prevent the SDSS satellites from adding significance to the MW's Vast Polar Structure (VPOS). We investigate whether this argument is valid by comparing the observed situation with model satellite distributions confined to the exact SDSS footprint area. We find that the SDSS satellites indeed add to the significance of the VPOS and that the survey footprint rather biases away from a close alignment between the plane fitted to the SDSS satellites and the plane fitted to the 11 classical satellites. Finding the observed satellite phase-space alignments of both the classical and SDSS satellites is a ~5σ event with respect to an isotropic distribution. This constitutes a robust discovery of the VPOS and makes it more significant than the Great Plane of Andromeda (GPoA). Motivated by the GPoA, which consists of only about half of M31's satellites, we also estimate which fraction of the MW satellites is consistent with being part of an isotropic distribution. Depending on the underlying satellite plane width, only 2 to 6 out of the 27 considered MW satellites are expected to be drawn from isotropy, and an isotropic component of >50% of the MW satellite population is excluded at 95% confidence.
