description: Recent improvements in high-throughput genotyping and sequencing technologies have afforded the collection of massive, genome-wide datasets of DNA information from hundreds of thousands of individuals. These datasets, in turn, provide unprecedented opportunities to reconstruct the history of human populations and detect genotype-phenotype association. Recently developed computational methods can identify long-range chromosomal segments that are identical across samples, and have been transmitted from common ancestors that lived tens to hundreds of generations in the past. These segments reveal genealogical relationships that are typically unknown to the carrying individuals. In this work, we demonstrate that such identical-by-descent (IBD) segments are informative about a number of relevant population genetics features: they enable the inference of details about past population size fluctuations, migration events, and they carry the genomic signature of natural selection.  We derive a mathematical model, based on coalescent theory, that allows for a quantitative description of IBD sharing across purportedly unrelated individuals, and develop inference procedures for the reconstruction of recent demographic events, where classical methodologies are statistically underpowered. We analyze IBD sharing in several contemporary human populations, including representative communities of the Jewish Diaspora, Kenyan Maasai samples, and individuals from several Dutch provinces, in all cases retrieving evidence of fine-scale demographic events from recent history. Finally, we expand the presented model to describe distributions for those sites in IBD shared segments that harbor mutation events, showing how these may be used for the inference of mutation rates in humans and other species.

description: Integral formulae for the correlation functions of the XYZ model with a boundary are calculated by mapping the model to the bosonized boundary SOS model. The boundary K-matrix considered here coincides with the known general solution of the boundary Yang-Baxter equation. For the case of diagonal K-matrix, our formulae reproduce the one-point function previously obtained by solving boundary version of quantum Knizhnik-Zamolodchikov equation.

Populist Counter-Spectacles and the Inception of Mass Media Art in Argentina:  Marta Minujín’s Happenings, Performances, and Environments of the 1960s

description: This monographic dissertation traces the development of happenings and mass media art in Argentina through the works that Argentine artist Marta Minujín created between 1961 and 1968. It argues that, in its unparalleled pursuit of a mass audience, Minujín’s art articulated a populist logic that allowed it to subvert authoritarianism in an oblique manner based in dissensus. This distinguished Minujín’s practice from that of other politically radicalized Argentine artists, who had turned their art into a form of activism and overt critique of the dictatorship of General Onganía. This dissertation also demonstrates that Minujín’s media-centric happenings and environments adopted a carnivalesque strategy of “positive negation” or ambiguous mimetic excess to reveal and critique the effects of an incipient spectacle culture.

description: This dissertation considers Jef Geys as an archivist of the cultural shifts of the ’60s and ’70s in Europe amidst the reception of American Pop in Belgium. Between these decades, Geys archived and played back the social and cultural effects of Pop to engage with the newly defined middle class that was constructed to account for and implement changes in both professional and social settings. Geys’s archive was instrumental in his roles as an artist and educator and he used it to reinterpret the implications of Pop. Geys’s consideration of Pop expanded its implications to test Pop’s institutional and social alignments in relation to the question of geography and population.

The Theory of Heating of the Solar Corona and Launching of the Solar Wind by Alfvén Waves

description: State-of-the-art MHD calculations reveal acceptable agreement with observational data for the height profile of the temperature $T(h)$ in the transition region of solar corona. Simultaneously, the velocity of the solar wind $U(h)$ has also been calculated. The developed method gives the possibility at given frequency dependent spectral density of Alfvén waves (AW) coming from chromosphere $\mathcal{W}(ω)$ to calculate both height profiles $T(h)$ and $U(h)$. In agreement with the concepts of the self-induced opacity of plasma with respect of AW, the narrow width $λ$ of the transition region is determined by the fast temperature increase of the viscosity $η(T,B)$. After more than 70 years of development of Solar physics, the Alfvén hypothesis of heating of the solar corona by AW has remained without alternatives; none of other mechanisms can explain $ab$ $initio$ the value of $λ$. The performed MHD analysis explains the height dependence of the non-thermal broadening of the chromospheric spectral lines and predicts angular dependence of this broadening with respect of position in solar disc. One can expect significant impact of MHD analysis in the interpretation of the long expected data from Parker Solar Probe.

description: A theorem of Glimm states that representation theory of an NGCR C*-algebra is always intractable, and the Cuntz algebra O_N is a case in point. The equivalence classes of irreducible representations under unitary equivalence cannot be captured with a Borel cross section. Nonetheless, we prove here that wavelet representations correspond to equivalence classes of irreducible representations of O_N, and they are effectively labeled by elements of the loop group, i.e., the group of measurable functions A:T-->U_N(C). These representations of O_N are constructed here from an orbit picture analysis of the infinite-dimensional loop group.

description: The rapid proliferation of large language models (LLMs) has stimulated researchers to seek effective and efficient approaches to deal with LLM hallucinations and low-quality outputs. Uncertainty quantification (UQ) is a key element of machine learning applications in dealing with such challenges. However, research to date on UQ for LLMs has been fragmented in terms of techniques and evaluation methodologies. In this work, we address this issue by introducing a novel benchmark that implements a collection of state-of-the-art UQ baselines and offers an environment for controllable and consistent evaluation of novel UQ techniques over various text generation tasks. Our benchmark also supports the assessment of confidence normalization methods in terms of their ability to provide interpretable scores. Using our benchmark, we conduct a large-scale empirical investigation of UQ and normalization techniques across eleven tasks, identifying the most effective approaches.

description: The out-of-equilibrium transport properties of a double quantum dot system in the Kondo regime are studied theoretically by means of a two-impurity Anderson Hamiltonian with inter-impurity hopping. The Hamiltonian, formulated in slave-boson language, is solved by means of a generalization of the non-crossing approximation (NCA) to the present problem. We provide benchmark calculations of the predictions of the NCA for the linear and nonlinear transport properties of coupled quantum dots in the Kondo regime. We give a series of predictions that can be observed experimentally in linear and nonlinear transport measurements through coupled quantum dots. Importantly, it is demonstrated that measurements of the differential conductance ${\cal G}=dI/dV$, for the appropriate values of voltages and inter-dot tunneling couplings, can give a direct observation of the coherent superposition between the many-body Kondo states of each dot. This coherence can be also detected in the linear transport through the system: the curve linear conductance vs temperature is non-monotonic, with a maximum at a temperature $T^*$ characterizing quantum coherence between both Kondo states.

description: We present a general method to determine the entropy current of relativistic matter at local thermodynamic equilibrium in quantum statistical mechanics. Provided that the local equilibrium operator is bounded from below and its lowest lying eigenvector is non-degenerate, it is proved that, in general, the logarithm of the partition function is extensive, meaning that it can be expressed as the integral over a 3D space-like hypersurface of a vector current, and that an entropy current exists. We work out a specific calculation for a non-trivial case of global thermodynamic equilibrium, namely a system with constant comoving acceleration, whose limiting temperature is the Unruh temperature. We show that the integral of the entropy current in the right Rindler wedge is the entanglement entropy.

Tunable magnetism of a hexagonal Anderson droplet on the triangular lattice

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: Motivated by recent progress on quantum engineered Kondo lattices, we numerically investigated the local magnetic properties of a hexagonal Anderson droplet consisting of multiple rings of magnetic atoms periodically arrayed on a triangular lattice. We demonstrated the tunability of the magnetic properties via their evolution with the droplet geometry for two types of systems with distinct local orbital occupancy profile. We found that the local susceptibility of the droplet center of some types of droplets can be remarkably enhanced in contrast to the conventionally rapid decrease due to spin correlations of surrounding droplet rings. The tunability of the magnetic properties is attributed to the charge redistribution with varying the droplet geometry enforced by the confined lattice with open boundary. Our simulations complements the exploration of the novel artificial tunability of engineered lattice systems.

As the nondiagonal components are similar to a gauge fields (in Kaluza - Klein's sense) then in some sense this solution is dual to the black hole in 4D Einstein - Yang - MIlls gravity: 4D black hole has the stationary area outside of event horizon but multidimensional wormhole inside null surface (on which $ds^2=0$).

description: Much has been said about what artists experience when they make visual art individually, but less has been said about what artists experience when they make art together. The study is based on the author’s perception, elaborated below, that artistic co-creation in the visual arts seems to be regarded as less valuable than individual artistic creation. To explore and richly describe the experience of artistic co-creation from the perspective of artists themselves, I initially invited three duos of artists to create visual art together in an experimental, time-bound co creation. After the onset of COVID-19, however, I amended the study by inviting participants to co-create art by virtually passing pieces of art to one another. I then interviewed them about their experience. Guided by a phenomenological approach, I conducted semi-structured interviews using questions sourced from the study purpose and related research questions. These interviews, held periodically through the co-creative project, sought to uncover the emergent themes of the experience of artistic co-creation. After reviewing the transcripts from these interviews, I created a representative written likeness of each duo experience, called a portrait, using the qualitative modes of portraiture. Six themes emerged from these portraits in the ways the artists reflected on their experiences of creating art together, including: moments of relationship and connection in the process of co-creation, the context and structure of the experiment, seeing experiences differently in the process of co-creation, finding agreements between the perspectives of the co-creators, developing creative rhythms based on temporal parameters, and learning in the partnership of the project. I did not begin this study with a formally-articulated conceptual framework, but I was influenced in my thinking by Basquiat and Warhol’s relationship and subsequent collaborative artworks. This research contributes to the literature in key areas by examining existing assumptions about the value of artistic co-creation in the visual arts.

description: My dissertation study portrayed how mature adults who had and practice their religious or spiritual convictions learned to develop spiritual friendships and how what they then learned from these friendships contributed to their own spiritual identity development. The study investigated how spiritual friendships, as learning schemes, gravitated towards learning and change by fostering critical reflection and encouraging the participants in such friendships to strive to be their best selves. The study also showed that spiritual friendships fostered personal and professional development that was linked to spiritual development. In particular, the study examined four spiritual friendships, involving nine participating spiritual friends (three dyads and one triad). It first uncovered how a spiritual friendship was initiated, developed, and maintained; then secondly, discussed how spiritual friendship cultivated the development of people in mature adulthood; and thirdly, explored how the learning and growth that occurred during the development procedure of the friendship contributed to the participants’ spiritual identity development. The study also defined what a spiritual friendship is as perceived and practiced by the research participants. The study employed portraiture, a qualitative research methodology, to paint a detailed representation of the participants’ lives, including their educational biographies, and to present their learning, formation, and development through practicing spiritual friendship. The study offers an in-depth and holistic portrayal of the paths the participating dyads and triads of the friendships walked as “fellow travelers” on their life voyages as these related to the formation of their spiritual selves in and through their spiritual friendships. It also sought to shed light on the triumphs of midlife and beyond: when people have gained greater experience, maturity, and capabilities, while at the same time they continued to grow and develop.

description: Drawing upon a critical constructivist framework and informed by scholarship on culturally relevant, responsive, and sustaining pedagogy (CRRSP) and student voice, this qualitative study utilizes portraiture methodology to render visible successful teaching practices for Latino male secondary students in urban contexts by answering the following two research questions: 1) What are the pedagogical practices of three White male teachers in one New York City public high school that their Latino male secondary students identify as successful in supporting their educational potential?; and 2) How do these three teachers make sense of these identified practices and their success with Latino male secondary students? To achieve these goals, data was collected from four sources: 1) ethnographic observations; 2) semi-structured individual interviews; 3) semi-structured focus group interviews; and 4) written documentation, and was analyzed using constructivist grounded theory. The final products of this work are three pedagogical portraits—written research documents that bridge science and art to lead to new or deeper understandings about teaching and learning. Findings from this study indicate the saliency of pedagogies that authentically care for Latino male students in urban areas, support their academic achievement, and explicitly draw connections between course content and students’ interests, lives, and future goals. The resulting portraits also encourage consideration of how attention to the development of Latino male students’ cultural and linguistic competence and dexterity as well as their sociopolitical awareness could further support the academic and personal growth of these young men. These findings: 1) contribute to a limited research base on successful teaching practices of Latino male secondary students in urban communities; 2) support more tailored recommendations for educational policy aimed at leveraging the unique potential of Latino young men in our nation’s cities; and 3) can inform the professional development of both pre-service and in-service school actors who work with Latino male students. Such contributions are particularly significant given the existing patterns of underachievement and untapped promise of Latino male youth across the country.

Grief in art

description: In Athens in the early 5th century BCE, a new genre of funerary vase, the white-ground lêkythos, appeared and quickly grew to be the most popular grave gift for nearly a century. These particular vases, along with their relatively delicate style of painting, ushered in a new funerary scene par excellence, which highlighted the sorrow of the living and the merits of the deceased by focusing on personal moments of grief in the presence of a grave. Earlier Attic funerary imagery tended to focus on crowded prothesis scenes where mourners announced their grief and honored the dead through exaggerated, violent and frenzied gestures. The scenes on white-ground lêkythoi accomplished the same ends through new means, namely by focusing on individual mourners and the emotional ways that mourners privately nourished the deceased and their memory. Such scenes combine ritual activity (i.e. dedicating gifts, decorating the grave, pouring libations) with emotional expressions of sadness, which make them more vivid and relatable. The nuances in the characteristics of the mourners indicate a new interest in adding an individual touch to the expression, which might “speak” to a particular moment or variety of sadness that might relate to a potential consumer. To facilitate a meaningful discussion of the range of ways that white-ground painters articulated grief and lament in their vases, the dissertation is divided into six chapters, each of which concentrates on a particular type of mourner: women, men, elderly men, infants, vocal visitors and the deceased. Discussing the visual iconography across these different groups demonstrates that the shared and individual, public and private, intentional and candid aspects of grief and mourning can be shown simultaneously and that it was of interest to the Athenians to look at images that incorporated all of these aspects.

It is found that both proposals, which require the equation of state of the single component system as input, lead to comparable accuracy when the same input is used in both, but the one advocated by Santos et al. is simpler and complies with the exact limit in which the small disks are point particles.

The specific solution presented here represents a wormhole connecting two asymptotically spatially flat regions. In general, the diameter of the wormhole throat, in units of the Planck length, can be arbitrarily large, depending on the values of the scalar coupling $ξ$ and the boundary values for the shape and redshift functions. In all cases we have considered, there is a fine-structure in the form of Planck-scale oscillations or ripples superimposed on the solutions.

Double Detonations with Thin, Modestly Enriched Helium Layers Can Make Normal Type Ia Supernovae

description: It has been proposed that Type Ia supernovae (SNe Ia) that are normal in their spectra and brightness can be explained by a double detonation that ignites first in a helium shell on the surface of the white dwarf (WD). This proposition is supported by the satisfactory match between simulated explosions of sub-Chandrasekhar-mass WDs with no surface He layer and observations of normal SNe Ia. However, previous calculations of He-ignited double detonations have required either artificial removal of the He shell ashes or extreme enrichment of the surface He layer in order to obtain normal SNe Ia. Here we demonstrate, for the first time in multi-dimensional full-star simulations, that a thin, modestly enriched He layer will lead to a SN Ia that is normal in its brightness and spectra. This strengthens the case for double detonations as a major contributing channel to the population of normal SNe Ia.

description: A recent detection of spatially extended gamma-ray emission in the central region of the Andromeda galaxy (M31) has led to several possible explanations being put forth, including dark matter annihilation and millisecond pulsars. Another possibility is that the emission in M31 can be accounted for with a purely astrophysical cosmic-ray (CR) scenario. This scenario would lead to a rich multi-wavelength emission that can, in turn, be used to test it. Relativistic cosmic-ray electrons (CRe) in magnetic fields produce radio emission through synchrotron radiation, while X-rays and gamma rays are produced through inverse Compton scattering. Additionally, collisions of primary cosmic-ray protons (CRp) in the interstellar medium produce charged and neutral pions that then decay into secondary CRe (detectable through radiative processes) and gamma-rays. Here, we explore the viability of a CR origin for multi-wavelength emission in M31, taking into consideration three scenarios: a CR scenario dominated by primary CRe, one dominated by CRp and the resulting secondary CRe and gamma rays from neutral pion decay, and a final case in which both of these components exist simultaneously. We find that the multi-component model is the most promising, and is able to fit the multi-wavelength spectrum for a variety of astrophysical parameters consistent with previous studies of M31 and of cosmic-ray physics. However, the CR power injection implied by our models exceeds the estimated CR power injection from typical astrophysical cosmic-ray sources such as supernovae.

description: The rise of on-demand platform work typified by Uber has intensified a decades-long trend away from standard work relationships and toward contingent work structures, characterized by the unbounding of work in space and time. Yet many workers have always toiled outside of a traditional workplace and “standard” schedule. My dissertation examines how contingent workers in four different industries navigate unstable work schedules across unsettled work geographies, drawing on 120 interviews with agricultural and oil and gas workers in Texas and on-demand delivery workers and university adjuncts in New York City. Across these “old” and “new” cases of contingent work performed across rural and urban landscapes, work processes restructure space and time in such a way that workers do not know when, for how long, or where they will have work. I call this temporal and spatial instability positional uncertainty – repurposing an oilfield term for the inability to pinpoint precisely where one is at any given moment in the drilling process. The experience of positional uncertainty forces workers to subordinate the rhythms and geographies of their own lives to the temporal and spatial imperatives of their respective labor processes, leading to time struggle (unpaid periods of waiting or “zombie time” and overwork) and challenges in space (related to the bifurcation or unbounding, respectively, of the spaces of work and home). Workers respond, first, by doing boundary work, and second, by telling both critical and anchoring stories in attempts to bring coherence and meaning to the day-to-day and the long-term. The dissertation highlights the integral role of time and space in structuring social life, the active maneuvers by which workers struggle to re-configure time and space to produce coherence and make a life for themselves, and the short- and long-term costs of the transfer of risk onto workers through positional uncertainty. The strategic comparison reveals parallel strategies across disparate cases in response to the warping of time and space and illuminates how positional uncertainty exacerbates deep-set structural inequalities.

description: Permeable reactive barriers (PRBs) can be a successful site management tool for groundwater impacted by Metal Leaching and Acid Rock Drainage (ML/ARD). Using a sustainable biological and chemical treatment approach, they intercept and passively treat dissolved metal contaminant plumes, thereby reducing risks to the receiving environment and downstream receptors. Drawing on previous experience with PRBs containing an innovative mixture of organic leaf compost, limestone and zero valent iron, we will discuss strategies for remediation of metal contaminant plumes. PRBs are flexible and can be adapted to site conditions. PRB design considers contaminant concentrations and plume morphology; then optimizes PRB physical configurations and media composition to best match target treatment performance requirements. Tandem treatment walls can be designed to intercept high dissolved metal concentrations. Principals for design and installation in tidally influenced foreshore environments are also considered including the placement of targeted media mixes. Installation techniques successfully applied to date have included a slurry-assisted continuous trenching method through sand and gravels and rejuvenation of existing walls using a caisson method to sustainably extend the life of PRB sections. A review of PRB geochemical performance has demonstrated successful reduction of metal concentrations through bacterially mediated sulphate reduction with formation of sulphide minerals, formation of mineral oxyhydroxides, and adsorption and co-precipitation with iron oxyhydroxides. Removal rates have been typically greater than 99% (for example, copper and zinc reductions from magnitudes of 10’s mg/L to <0.001 mg/L). Mineralogical analysis of media cores indicated the formation of sulphides, secondary precipitates, and oxyhydroxides. PRBs provide a site-specific, flexible and effective approach to address management of groundwater ML/ARD in a variety of mine site applications; therefore, reducing potential impacts to the environment. In the presentation, we will explore potential design and installation strategies for PRBs and their remediation performance.

description: The NeuroSAT neural network architecture was recently introduced for predicting properties of propositional formulae. When trained to predict the satisfiability of toy problems, it was shown to find solutions and unsatisfiable cores on its own. However, the authors saw "no obvious path" to using the architecture to improve the state-of-the-art. In this work, we train a simplified NeuroSAT architecture to directly predict the unsatisfiable cores of real problems. We modify several high-performance SAT solvers to periodically replace their variable activity scores with NeuroSAT's prediction of how likely the variables are to appear in an unsatisfiable core. The modified MiniSat solves 10% more problems on SAT-COMP 2018 within the standard 5,000 second timeout than the original does. The modified Glucose solves 11% more problems than the original, while the modified Z3 solves 6% more. The gains are even greater when the training is specialized for a specific distribution of problems; on a benchmark of hard problems from a scheduling domain, the modified Glucose solves 20% more problems than the original does within a one-hour timeout. Our results demonstrate that NeuroSAT can provide effective guidance to high-performance SAT solvers on real problems.
Positional Coordinates for Spinal Sensory-Motor Connectivity

description: One of the essential requirements for accurate functioning of the nervous system is that synaptic connections are formed and neural circuits are assembled with precision. Two major contributors to the establishment of selective synapse formation are thought to be the positional and molecular identities of neurons. In many instances, the fine-grained precision of synaptic connectivity is thought to occur through a process of molecular recognition that depends on the interaction of complementary recognition molecules expressed on pre- and post-synaptic partners. However, the lack of experimental observations suggests that this is perhaps not the predominant mechanism used in assembling neural networks. In addition to molecular recognition mechanisms, the range of alternative postsynaptic targets can be reduced by organized patterns of neuronal position and axonal growth and termination to deliver the terminals of appropriate pre- and postsynaptic partners to restricted volumes of the developing nervous system. Thus, the positional identities of neurons carry significance in establishing neural networks. The selectivity with which sensory axons form connections with spinal motor neurons drives coordinated motor behavior. The precise profile of monosynaptic sensory-motor connectivity has been suggested to have its origins in the recognition of motor neuron subtypes by group Ia sensory afferents.  Here I present an analysis of sensory-motor connectivity patterns in mice in which the normal clustering and positioning of motor neurons has been scrambled through genetic manipulations to conditionally knock out the transcription factor FoxP1. FoxP1, together with an intricate network of Hox genes, drives molecular differentiation programs that give rise to the molecular diversity observed in limb level motor neurons. Conditional ablation of FoxP1 in motor neurons causes scrambling of the motor neurons as well as normalization of molecular identity among all limb level motor neurons. My findings in the conditional FoxP1 mutant mice indicate that critical steps in the patterning of sensory-motor connectivity are governed more by the dorsoventral position of motor neurons than by their identity. My findings imply that sensory-motor specificity in monosynaptic reflex arcs depends on the ability of group Ia sensory afferents to target discrete dorsoventral domains of the spinal cord in a manner that is independent of motor neuron subtype identities, and even of motor neurons themselves. Motor pool clustering and positioning may therefore have evolved to ensure that the motor neurons that innervate a specific limb muscle are able to receive synaptic input from the group Ia sensory afferents supplying the same muscle.
