description: The Mott transition is one of the fundamental issues in condensed matter physics, especially in the system with antiferromagnetic long-range order. However the Mott transition in quantum spin liquid (QSL) systems without long-range order is rare. Here we report the observation of the pressure-induced insulator to metal transition followed by the emergence of superconductivity in the QSL candidate NaYbSe2 with triangular lattice of 4f Yb$_3^+$ ions. Detail analysis of transport properties at metallic state shows an evolution from non-Fermi liquid to Fermi liquid behavior when approaching the vicinity of superconductivity. An irreversible structure phase transition occurs around 11 GPa is revealed by the X-ray diffraction. These results shed light on the Mott transition and superconductivity in the QSL systems.

description: This project addresses the motives behind and interpretative outcomes of Christological sculptures of St. John the Baptist’s severed head in fifteenth-century England. These sculptures depart from the iconography of John’s death in Scripture and instead align with an English eucharistic lesson on the saint’s head. I theorize that tensions between two groups of viewers—the authorities of the Church who were likely responsible for the initial promotion of John’s head sculptures and the laypeople who purchased them on the open market—contributed to the degree to which the sculptures served to visually advance the idea of eucharistic consecration. Drawing on English Catholic and early reformist teachings on the Eucharist, as well as lay devotional art produced in reaction to these challenges, I propose that John’s head sculptures mediated between lay desire to behold the body of Christ while reaffirming the Catholic Church as the sole custodian of the Eucharist.

description: Coupling phase-stable single-cycle terahertz (THz) pulses to scanning tunneling microscope (STM) junctions enables spatio-temporal imaging with femtosecond temporal and Ångstrom spatial resolution. The time resolution achieved in such THz-gated STM is ultimately limited by the sub-cycle temporal variation of the tip-enhanced THz field acting as an ultrafast voltage pulse, and hence by the ability to feed high-frequency, broadband THz pulses into the junction. Here, we report on the coupling of ultrabroadband (1-30 THz) single-cycle THz pulses from a spintronic THz emitter(STE) into a metallic STM junction. We demonstrate broadband phase-resolved detection of the THz voltage transient directly in the STM junction via THz-field-induced modulation of ultrafast photocurrents. Comparison to the unperturbed far-field THz waveform reveals the antenna response of the STM tip. Despite tip-induced low-pass filtering, frequencies up to 15 THz can be detected in the tip-enhanced near-field, resulting in THz transients with a half-cycle period of 115 fs. We further demonstrate simple polarity control of the THz bias via the STE magnetization, and show that up to 2 V THz bias at 1 MHz repetition rate can be achieved in the current setup. Finally, we find a nearly constant THz voltage and waveform over a wide range of tip-sample distances, which by comparison to numerical simulations confirms the quasi-static nature of the THz pulses. Our results demonstrate the suitability of spintronic THz emitters for ultrafast THz-STM with unprecedented bandwidth of the THz bias, and provide insight into the femtosecond response of defined nanoscale junctions.

description: In many real-world settings, a team of agents must coordinate its behaviour while acting in a decentralised fashion. At the same time, it is often possible to train the agents in a centralised fashion where global state information is available and communication constraints are lifted. Learning joint action-values conditioned on extra state information is an attractive way to exploit centralised learning, but the best strategy for then extracting decentralised policies is unclear. Our solution is QMIX, a novel value-based method that can train decentralised policies in a centralised end-to-end fashion. QMIX employs a mixing network that estimates joint action-values as a monotonic combination of per-agent values. We structurally enforce that the joint-action value is monotonic in the per-agent values, through the use of non-negative weights in the mixing network, which guarantees consistency between the centralised and decentralised policies. To evaluate the performance of QMIX, we propose the StarCraft Multi-Agent Challenge (SMAC) as a new benchmark for deep multi-agent reinforcement learning. We evaluate QMIX on a challenging set of SMAC scenarios and show that it significantly outperforms existing multi-agent reinforcement learning methods.

Using math scores from SAEB between 2003 and 2017, I estimate that the performance gap between private and public school students became narrowed and eventually became statistically not significant in 2017. Further, while the White-Black performance gap also became statistically non-significant by 2017 for private school students, it barealy changed at all for public school students between 2003 and 2017.

LOUIS CARLOS BERNAL’S BARRIOS: THE POLITICS OF DOMESTICITY IN THE WAKE OF THE CHICANO MOVEMENT
Creators: name: Coffey, Charlie P.
Publisher: name: American University
Year: 2023

description: In 1978, the Mexican American Legal Defense and Education Fund commissioned five photographers to document Mexican American life in the American Southwest for an exhibition titled “ESPEJO.” Unlike other photographers included in the project, Louis Carlos Bernal turned his camera toward the domestic sphere, creating intimate, colorful documents of both people and interiors in the Mexican American communities of his native Arizona. This thesis examines how the political beliefs and strategies of the historical Chicano movement informed Bernal’s Barrios series. I argue that—through their portrayal of the home and its manifestations of cultural identity—the photographs reflect claims for Mexican American land ownership in the Southwest, an idea that was championed during the movement. While deeply informed about the historical Chicano movement of the 1960s and 1970s, which the “ESPEJO” project was a result of, Bernal avoided straightforward portrayals of Chicanx activism or struggle in his Barrios series. In this way, the series sought to define the legacy of the Chicano movement by picturing a Southwest wherein the movement’s goals had been realized.

description: Psychological health condition is known to be complex and multidimensional, with several scales developed as measures of its symptoms. The absence or presence of negative symptoms has been used to describe the state of psychological well-being and psychological ill-being, respectively. This study gathered 48 validated items from previous studies as symptoms of psychological health conditions. The 48 symptoms identified were explored among 300 construction employees in Ghana to determine their psychological health status. Thematic analysis was used to group the 48 symptoms into four main constructs, namely: physical symptoms, emotional symptoms, cognitive symptoms, and behavioral symptoms. A comparative analysis was conducted with the two groups of respondents, namely construction professionals and construction trade workers, to identify the group that is more prevalent with psychological well-being or ill-being conditions. The findings revealed that a significant number of the respondents had experienced the negative symptoms of psychological health conditions. The study also revealed statistically significant differences in the level of experience of psychological health conditions among the two construction employees, with psychological ill-being conditions found to be more prevalent in construction trade workers than the construction professionals. The findings from the study confirm the need to develop preventive psychological health management models for construction employees. The 48 symptoms put together as a measure for psychological health status had an acceptable internal consistency and reliability, and hence can be adopted by researchers and stakeholders to determine psychological health status. This study, therefore, makes an impactful contribution to the field of occupational health psychology.

A hypoeutectic Al–22.5 wt pctCu sample was processed using the Electro-Magnetic Levitator on board of the International Space Station within the frame of the European Space Agency projects NEQUISOL and THERMOLAB. In total, 21 cycles of melting and cooling were carried out, with the last cycle yielding a primary undercooling of 20 K and a eutectic undercooling of 35 K. The density, surface tension, and viscosity of the liquid sample were measured using the oscillating drop method and a high-speed camera. The evolution of the temperature was recorded with a pyrometer. The oscillations of the drop appear modulated, indicative of a nonlinear behavior caused by rotation, precession, nutation of the sample, and high initial deformation. Nevertheless, the measurements are in line with previous experimental results for alloys of similar composition and with theoretical predictions. These results highlight the potential of the method to build an extensive and reliable database of the thermophysical properties of pure metals and alloys.

If the program is successful, the short-term practical implications for agriculture are most pronounced for the EC's food and agribusiness sector with indirect effects on farming. The long-term implications of Europe 1992 for EC agriculture are profound as true common prices in a borderless EC-12 would lead to specialization in agriculture at the expense of the current degree of nationalization.

On the regularization ambiguities in loop quantum gravity

description: One of the main achievements of LQG is the consistent quantization of the Wheeler-DeWitt equation which is free of UV problems. However, ambiguities associated to the intermediate regularization procedure lead to an apparently infinite set of possible theories. The absence of an UV problem is intimately linked with the ambiguities arising in the quantum theory. Among these ambiguities there is the one associated to the SU(2) unitary rep. used in the diffeomorphism covariant pointsplitting regularization of nonlinear funct. of the connection. This ambiguity is labelled by a halfinteger m and, here, it is referred to as the m-ambiguity. The aim of this paper is to investigate the important implications of this ambiguity./ We first study 2+1 gravity quantized in canonical LQG. Only when the regularization of the quantum constraints is performed in terms of the fundamental rep. of the gauge group one obtains the usual TQFT. In all other cases unphysical local degrees of freedom arise at the level of the regulated theory that conspire against the existence of the continuum limit. This shows that there is a clear cut choice in the quantization of the constraints in 2+1 LQG./ We then analyze the effects of the ambiguity in 3+1 gravity exhibiting the existence of spurious solutions for higher unit. rep. quantizations of the Hamiltonian constraint. Although the analysis is not complete in D=3+1--due to the difficulties associated to the definition of the physical inner product--it provides evidence supporting the definitions quantum dynamics of loop quantum gravity in terms of the fundamental representation of the gauge group as the only consistent possibilities. If the gauge group is SO(3) we find physical solutions associated to spin-two local excitations.

As a first application, we give a simpler proof of Voisin's Theorem for general canonical curves. This completely determines the terms of the minimal free resolution of the coordinate ring of such curves. Secondly, in the case of curves of even genus, we enhance Voisin's Theorem by providing a structure theorem for the last syzygy space, resolving the Geometric Syzygy Conjecture in even genus.

description: We calculate the neutrino mean free path and the Equation of State of pure neutron matter at finite temperature within a selfconsistent scheme based on the Brueckner--Hartree--Fock approximation. We employ the nucleon-nucleon part of the recent realistic baryon-baryon interaction (model NSC97e) constructed by the Nijmegen group. The temperatures considered range from 10 to 80 MeV. We report on the calculation of the mean field, the residual interaction and the neutrino mean free path including short and long range correlations given by the Brueckner--Hartree--Fock plus Random Phase Approximation (BHF+RPA) framework. This is the first fully consistent calculation in hot neutron matter dedicated to neutrino mean free path. We compare systematically our results to those obtain with the D1P Gogny effective interaction, which is independent of the temperature. The main differences between the present calculation and those with nuclear effective interactions come from the RPA corrections to BHF (a factor of about 8) while the temperature lack of consistency accounts for a factor of about 2.

description: We consider the mechanical equilibrium and stability of matter trapped in the magnetosphere of a rapidly rotating star. Assuming a dipolar magnetic field and arbitrary inclination of the magnetic axis with respect to the axis of rotation we find stable equilibrium positions a) in a (warped) disk roughly aligned with the magnetic equatorial plane and b) at two locations above and below the disk, whose distance from the star increases with decreasing inclination angle between dipole and rotation axis. The distribution of matter is not strongly affected by allowing for a spatial offset of the magnetic dipole. These results provide a possible explanation for some observations of corotating localized mass concentrations in hot magnetic stars.

description: The operator product expansion is used to obtain model-independent predictions for the first two moments of the renormalized B-meson light-cone distribution amplitude phi_+(omega,mu), defined with a cutoff omega>mu. By solving the evolution equation for the distribution amplitude, an integral representation for phi_+(omega,mu) is obtained in terms an initial function phi_+(omega,mu_0) defined at a lower renormalization scale. A realistic model of the B-meson light-cone distribution amplitude is proposed, which satisfies the moment relations and has the correct asymptotic behavior. This model provides an estimate for the first inverse moment and the associated parameter lambda_B.

description: The use of machine learning algorithms in finance, medicine, and criminal justice can deeply impact human lives. As a consequence, research into interpretable machine learning has rapidly grown in an attempt to better control and fix possible sources of mistakes and biases. Tree ensembles offer a good prediction quality in various domains, but the concurrent use of multiple trees reduces the interpretability of the ensemble. Against this background, we study born-again tree ensembles, i.e., the process of constructing a single decision tree of minimum size that reproduces the exact same behavior as a given tree ensemble in its entire feature space. To find such a tree, we develop a dynamic-programming based algorithm that exploits sophisticated pruning and bounding rules to reduce the number of recursive calls. This algorithm generates optimal born-again trees for many datasets of practical interest, leading to classifiers which are typically simpler and more interpretable without any other form of compromise.

ZHANG DAQIAN: THE POLITICS OF DIVINE REDWOOD TREES IN POST-WAR TAIWAN
Creators: name: Cox, Adrienne
Publisher: name: American University
Year: 2023

description: Zhang Daqian, one of the most productive and visionary ink painters in modern China, has received attention inadequate to his importance in English-language scholarship, which primarily focuses on Zhang’s biography. As a result, his paintings in American collections, such as Divine Redwood Trees in Taiwan (1970), have yet to be critically discussed. This thesis scrutinizes Divine Redwoods through a three step process to create a more thorough understanding of Zhang’s career and paintings. I begin by breaking down Zhang’s title “Picasso of the East” to dispel misconceptions surrounding his splashed ink practice. Then I position Zhang in the history of splashed ink in order to emphasize Zhang’s historical connection to Chinese precedents. Finally, I interpret Divine Redwoods by discussing the iconography of the painting in connection to the politically charged inscription written by Zhang. I argue that Divine Redwoods, while an example of Zhang’s signature splashed ink, is imbued with the painter’s political ideology. It represents his dedication to upholding Chinese cultural heritage and recognizing the Republic of China in Taiwan as the modern inheritor of Chinese history and culture.

description: Insect defoliators alter biogeochemical cycles from land into receiving waters by consuming terrestrial biomass and releasing biolabile frass. Here, we related insect outbreaks to water chemistry across 12 boreal lake catchments over 32-years. We report, on average, 27% lower dissolved organic carbon (DOC) and 112% higher dissolved inorganic nitrogen (DIN) concentrations in lake waters when defoliators covered entire catchments and reduced leaf area. DOC reductions reached 32% when deciduous stands dominated. Within-year changes in DOC from insect outbreaks exceeded 86% of between-year trends across a larger dataset of 266 boreal and north temperate lakes from 1990 to 2016. Similarly, within-year increases in DIN from insect outbreaks exceeded local, between-year changes in DIN by 12-times, on average. As insect defoliator outbreaks occur at least every 5 years across a wider 439,661 km2 boreal ecozone of Ontario, we suggest they are an underappreciated driver of biogeochemical cycles in forest catchments of this region.

description: We investigate the emissivity properties of the main near-IR transitions of the Fe+ ion in the conditions prevailing in the inner regions of jets from young stars, based on a simplified 16-level atom model. We present new diagnostic diagrams involving prominent near-IR line ratios that allow us to constrain the electronic density, temperature, and Fe gas phase abundance ratio, independently of the heating process. Comparison with recent near-IR observations of a sample of HH objects indicates gas phase Fe abundances ranging from 15-50 % up to 100 % of the solar value in agreement with the moderate depletions previously derived from optical line ratios or shock models. Hence, it appears that Fe-bearing dust is efficiently destroyed in stellar jets. We then use our Fe+ emissivity model to predict near-IR [Fe II] emission maps for self-similar, cold MHD disk wind models. We show that observations in [Fe II] with AMBER on the VLTI could severely constrain the MHD solution and the inner launch radius of the jet. We also compare theoretical predictions with recent observations in the near-IR [Fe II] lines of the L1551-IRS5 and DG Tau jets. The cold disk wind model reproduces quite well the two velocity components observed at -100 and -300 km/s, although the high velocity component appears overestimated by a factor of 1.5 in the DG Tau jet. However, the model predicts too little emission at intermediate-velocity and insufficient densities. Denser disk winds with stronger heating at the jet base, which have been invoked for optical jets, also appear needed in younger, embedded Class I jet sources.

description: Past research has neglected irrelevant dimensions of visual warning signals in choice reaction-time tasks. The present study examined the effects of an irrelevant dimension of a visual warning signal and that signal's value in predicting a response stimulus on choice reaction time. A warning signal, which was a geometric figure, appeared in the center of a VDT screen and was followed by one of two response stimuli (open circles). The predictive value of the warning signal was defined as the percentage of trials during which the warning signal accurately predicted the response stimulus by size and was manipulated in the present study as either .50, .66, .83 or 1.00. On half of the trials, an irrelevant dimension of the warning signal — its shape — was also varied. 24 male and 24 female subjects participated for 240 trials each. The results indicated that the fastest reaction times and lowest number of errors occurred when the predictive value was 1.00. However, there were no differences in reaction time between the conditions with predictive values of .50, .66, or .83. No errors were made when shape of the warning signal was varied (irrelevant dimension) than when it was not. These results support the hypothesis that predictive values of less than 1.00 as well as variations in an irrelevant dimension of a warning signal cause response competition in information processing, resulting in slower reaction times or increased number of errors.

description: Zhang Daqian, one of the most productive and visionary ink painters in modern China, has received attention inadequate to his importance in English-language scholarship, which primarily focuses on Zhang’s biography. As a result, his paintings in American collections, such as Divine Redwood Trees in Taiwan (1970), have yet to be critically discussed. This thesis scrutinizes Divine Redwoods through a three step process to create a more thorough understanding of Zhang’s career and paintings. I begin by breaking down Zhang’s title “Picasso of the East” to dispel misconceptions surrounding his splashed ink practice. Then I position Zhang in the history of splashed ink in order to emphasize Zhang’s historical connection to Chinese precedents. Finally, I interpret Divine Redwoods by discussing the iconography of the painting in connection to the politically charged inscription written by Zhang. I argue that Divine Redwoods, while an example of Zhang’s signature splashed ink, is imbued with the painter’s political ideology. It represents his dedication to upholding Chinese cultural heritage and recognizing the Republic of China in Taiwan as the modern inheritor of Chinese history and culture.

description: Immunotherapies use components of the patient immune system to selectively target cancer cells. The use of CAR T cells to treat B-cell malignancies --leukaemias and lymphomas-- is one of the most successful examples, with many patients experiencing long-lasting complete responses to this therapy. This treatment works by extracting the patient's T cells and adding them the CAR group, which enables them to recognize and target cells carrying the antigen CD19+, that is expressed in these haematological tumors. Here we put forward a mathematical model describing the time response of leukaemias to the injection of CAR T-cells. The model accounts for mature and progenitor B-cells, tumor cells, CAR T cells and side effects by incorporating the main biological processes involved. The model explains the early post-injection dynamics of the different compartments and the fact that the number of CAR T cells injected does not critically affect the treatment outcome. An explicit formula is found that provides the maximum CAR T cell expansion in-vivo and the severity of side effects. Our mathematical model captures other known features of the response to this immunotherapy. It also predicts that CD19+ tumor relapses could be the result of the competition between tumor and CAR T cells analogous to predator-prey dynamics. We discuss this fact on the light of available evidences and the possibility of controlling relapses by early re-challenging of the tumor with stored CAR T cells.

description: Creating a community of fans are a key part of creating a sustainable career for a musician. When musicians are better able to articulate the fan experience, they are able to create more strategic and personable marketing strategies that will lead to deep fan loyalty. This thesis begins with a explores communication theories through William Brown’s framework. Based on his 2015 framework of audience involvement processes, this thesis aims to uncover how musicians activate their fan communities. After examining William Brown's framework, this research interviews music managers to discover how musicians activate their fan communities. These relationships are likely to evolve as social media continues to encourage and deepen the interactivity possible in the fan-celebrity relationship, making it more important than ever to understand how relationships with celebrities contribute to fans' identities and what effect they have socially and culturally. Drawing from the knowledge of psychology, social sciences, and cultural theory, this research suggests ways musicians can better engage their fan communities.

description: We have carried out an ultrahigh-field cyclotron resonance study of p-type In1-xMnxAs films, with Mn composition x ranging from 0% to 2.5%, grown on GaAs by low-temperature molecular-beam epitaxy. Pulsed magnetic fields up to 500 T were used to make cyclotron resonance observable in these low-mobility samples. The clear observation of hole cyclotron resonance is direct evidence of the existence of a large number of itinerant, effective-mass-type holes rather than localized d-like holes. It further suggests that the p-d exchange mechanism is more favorable than the double exchange mechanism in this narrow gap InAs-based dilute magnetic semiconductor. In addition to the fundamental heavy-hole and light-hole cyclotron resonance absorption appearing near the high-magnetic-field quantum limit, we observed many inter-Landau-level absorption bands whose transition probabilities are stronglydependent on the sense of circular polarization of the incident light.

description: The smaller the phytoplankton, the greater effort is required to distinguish individual cells by optics-based methods. Flow cytometry is widely applied in marine picophytoplankton research, but in freshwater research its role has remained minor. We compared epifluorescence microscopy and flow cytometry in assessing the composition, abundance and cell sizes of autofluorescent picophytoplankton in epilimnia of 46 Finnish lakes. Phycocyanin-rich picocyanobacteria were the most dominant. The two methods yielded comparable total picophytoplankton abundances, but the determination of cell sizes, and thus total biomasses, were on average an order of magnitude higher in the microscopy results. However, flow cytometry yielded higher cell sizes when applied on small-celled cultured algae. Our study demonstrated that both epifluorescence microscopy and flow cytometry are useful methods in assessing abundances of phycocyanin-rich and phycoerythrin-rich picocyanobacteria and eukaryotic picophytoplankton in lakes. However, accurate determination of cell size and biomass remain challenges for microscopy and especially for flow cytometry.

description: We present a comprehensive study of the cosmological solutions of 6D braneworld models with azimuthal symmetry in the extra dimensions, moduli stabilization by flux or a bulk scalar field, and which contain at least one 3-brane that could be identified with our world. We emphasize an unusual property of these models: their expansion rate depends on the 3-brane tension either not at all, or in a nonstandard way, at odds with the naive expected dimensional reduction of these systems to 4D general relativity at low energies. Unlike other braneworld attempts to find a self-tuning solution to the cosmological constant problem, the apparent failure of decoupling in these models is not associated with the presence of unstabilized moduli; rather it is due to automatic cancellation of the brane tension by the curvature induced by the brane. This provides some corroboration for the hope that these models provide a distinctive step toward understanding the smallness of the observed cosmological constant. However, we point out some challenges for obtaining realistic cosmology within this framework.
