description: A contragenic function in a domain $Ω\subseteq\mathbf{R}^3$ is a reduced-quaternion-valued (i.e. the last coordinate function is zero) harmonic function, which is orthogonal in $L^2(Ω)$ to all monogenic functions and their conjugates. The notion of contragenicity depends on the domain and thus is not a local property, in contrast to harmonicity and monogenicity. For spheroidal domains of arbitrary eccentricity, we relate standard orthogonal bases of harmonic and contragenic functions for one domain to another via computational formulas. This permits us to show that there exist nontrivial contragenic functions common to the spheroids of all eccentricities.

description: In laboratory experiments, we study the motion of levitated, sedimenting clouds of sub-mm grains at low ambient pressure and at high solid-to-gas ratios $ε$. The experiments show a collective behavior of particles, i.e. grains in clouds settle faster than an isolated grain. In collective particle clouds, the sedimentation velocity linearly depends on $ε$ and linearly depends on the particle closeness $C$. However, collective behavior only sets in at a critical value $ε_{\rm crit}$ which linearly increases with the experiment Stokes number St. For $\rm St <0.003 $ particles always behave collectively. For large Stokes numbers, large solid-to-gas ratios are needed to trigger collective behavior, e.g. $ε_{\rm crit} = 0.04$ at $\rm St = 0.01$. Applied to protoplanetary disks, particles in dense environments will settle faster. In balance with upward gas motions (turbulent diffusion, convection) the thickness of the midplane particle layer will be smaller than calculated based on individual grains, especially for dust. For pebbles, large solid-to-gas ratios are needed to trigger instabilities based on back-reaction.

description: The PREX-2 and CREX experiments in Hall A at Jefferson Lab are precision measurements of parity violating elastic electron scattering from complex nuclei. One requirement was that the incident electron beam polarization, typically $\approx$90\%, be known with 1\% precision. We commissioned and operated a Møller polarimeter on the beam line that exceeds this requirement, achieving a precision of 0.89\% for PREX-2, and 0.85\% for CREX. The uncertainty is purely systematic, accumulated from several different sources, but dominated by our knowledge of the target polarization. Our analysis also demonstrates the need for accurate atomic wave functions in order to correct for the Levchuk Effect. We describe the details of the polarimeter operation and analysis, as well as (for CREX) a comparison to results from a different polarimeter based on Compton scattering.

description: We report a method for acquiring Foucault images and small-angle electron diffraction patterns in external magnetic fields using a conventional transmission electron microscope without any modification. In the electron optical system that we have constructed, external magnetic fields parallel to the optical axis can be controlled using the objective lens pole piece under weak excitation conditions in the Foucault mode and the diffraction mode. We observe two ferromagnetic perovskite-type manganese oxides, La$_{0.7}$Sr$_{0.3}$MnO$_{3}$ and Nd$_{0.5}$Sr$_{0.5}$MnO$_{3}$, in order to visualize magnetic domains and their magnetic responses to external magnetic fields. In rhombohedral-structured La$_{0.7}$Sr$_{0.3}$MnO$_{3}$, pinning of magnetic domain walls at crystallographic twin boundaries was found to have a strong influence on the generation of new magnetic domains in external applied magnetic fields.

description: Major changes in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) food packages that were implemented in 2009 included reductions in the amount of milk and 100% juices, as well as the removal of whole milk from food packages. In analyzing the effect of these changes on the beverage consumption of Texas WIC children ages two to four, we found a significant decrease in the amount of whole milk consumed, and this decrease was partially offset by the increase in the amount of lower-fat milks consumed. Intakes of both desirable and undesirable nutrients from milk were decreased.

This region is interesting since it can lead to the new recently discussed baryogenesis and Dark Matter production mechanisms. We fully analyze different models for the production of Dark Matter and baryogenesis as well as the possibilities of discovery at the current and future experiments.

Remarks on Tachyon Driven Cosmology

description: We begin by reviewing the results on the decay of unstable D-branes in type II string theory, and the open-closed string duality proposal that arises from these studies. We then apply this proposal to the study of tachyon driven cosmology, namely cosmological solutions describing the decay of unstable space filling D-branes. This naturally gives rise to a time reversal invariant bounce solution with positive spatial curvature. In the absence of a bulk cosmological constant the universe always begins with a big bang and ends in a big crunch. In the presence of a bulk cosmological constant one may get non-singular cosmological solutions for some special range of initial conditions on the tachyon.

On the Energy Coupling Efficiency of AGN Outbursts in Galaxy Clusters

description: Active galactic nucleus (AGN) jets are believed to be important in solving the cooling flow problem in the intracluster medium (ICM), while the detailed mechanism is still in debate. Here we present a systematic study on the energy coupling efficiency $η_{\rm cp}$, the fraction of AGN jet energy transferred to the ICM. We first estimate the values of $η_{\rm cp}$ analytically in two extreme cases, which are further confirmed and extended with a parameter study of spherical outbursts in a uniform medium using hydrodynamic simulations. We find that $η_{\rm cp}$ increases from $\sim 0.4$ for a weak isobaric injection to $\gtrsim 0.8$ for a powerful point injection. For any given outburst energy, we find two characteristic outburst powers that separate these two extreme cases. We then investigate the energy coupling efficiency of AGN jet outbursts in a realistic ICM with hydrodynamic simulations, finding that jet outbursts are intrinsically different from spherical outbursts. For both powerful and weak jet outbursts, $η_{\rm cp}$ is typically around $0.7-0.9$, partly due to the non-spherical nature of jet outbursts, which produce backflows emanating from the hotspots, significantly enhancing the ejecta-ICM interaction. While for powerful outbursts a dominant fraction of the energy transferred from the jet to the ICM is dissipated by shocks, shock dissipation only accounts for $\lesssim 30\%$ of the injected jet energy for weak outbursts. While both powerful and weak outbursts could efficiently heat cooling flows, powerful thermal-energy-dominated jets are most effective in delaying the onset of the central cooling catastrophe.

On the Co-Evolution of the AGN and Star-Forming Galaxy Ultraviolet Luminosity Functions at 3 < z < 9

description: Studies of the high-redshift rest-frame ultraviolet (UV) luminosity functions (LFs) have typically treated the star-forming galaxy and active galactic nuclei (AGN) populations separately, as they have different survey depth and area requirements. However, the recent advent of wide-area deep ground-based imaging surveys now probe volumes large enough to discover AGNs, at depths sensitive enough for fainter star-forming galaxies, bridging these two populations. Using results from such surveys as observational constraints, we present a methodology to jointly empirically model the evolution of the rest-UV luminosity functions at z=3-9. We assume both populations have a LF well-described by a double power law modified to allow a flattening at the faint-end, and that all LF parameters evolve smoothly with redshift. This provides a good fit to the observations, and makes predictions to volume densities and redshifts not yet observed. We find that the volume density of bright (M_UV = -28) AGNs rises by five orders of magnitude from z=9 to z=3, while modestly bright (M_UV = -21) galaxies rise by only two orders of magnitude across the same epoch. The observed bright-end flattening of the z=9 LF is unlikely to be due to AGN, and rather is due to a shallowing of the bright-end slope, implying reduced feedback in bright galaxies at early times. Integrating our LFs we find that the intrinsic ionizing emissivity is dominated by galaxies at all z > 3, and this result holds even after applying a notional escape fraction. We compare our AGN LFs to predictions based on different black-hole seeding models, finding decent agreement on average, but that all models are unable to predict the observed abundance of bright AGNs. We make predictions for the upcoming Euclid and Roman observatories, showing that their respective wide-area surveys should be capable of discovering AGNs to z ~ 8.

description: We have used spectra obtained as part of the Science Verification program of the FLAMES multi-object spectrograph mounted on Kueyen (VLT-UT2) to perform an abundance analysis of stars along the giant branch (RGB) in the globular cluster NGC 2808. Sodium abundances are derived from Na D lines for a sample of 81 cluster stars spanning a range of about 2 magnitudes from the tip of the RGB. Our results show that a large star-to-star scatter does exist at all positions along the RGB, suggesting large variations in the abundance of proton capture elements down to luminosities comparable to the red horizontal branch (HB). The distribution of Na abundances along the RGB seems to point out that in this cluster most of the observed spread has a primordial origin. Overimposed evolutionary effects, if any, must be only at ``noise'' level, at odds with results from a similar analysis in M 13 (Pilachowski et al. 1996). This study is a first step towards ascertaining if a link exists between the distribution of chemical anomalies in light elements along the RGB and the global properties of globular clusters, in particular the HB morphology.

description: Lymphatic dysfunction is associated with the progression of many cardiovascular disorders due to their role in maintaining tissue fluid homeostasis. Promoting new lymphatic vessels (lymphangiogenesis) is a promising strategy to reverse these cardiovascular disorders via restoring lymphatic function. Vascular endothelial growth factor (VEGF) members VEGF-C and VEGF-D are both potent candidates for stimulating lymphangiogenesis, though main- taining spatial and temporal control of these factors represents a challenge to developing efficient therapeutic lymphangiogenic applications. Injectable alginate hydrogels have been useful for the controlled delivery of many angiogenic factors, including VEGF-A, to stimulate new blood vasculature. However, the utility of these tunable hydrogels for delivering lym- phangiogenic factors has never been closely examined. Thus, the objective of this study was to utilize ionically cross-linked alginate hydrogels to deliver VEGF-C and VEGF-D for potential lymphangiogenic applications. We demonstrated that lymphatic endothelial cells (LECs) are sensitive to temporal presentation of VEGF-C and VEGF-D but with different responses between the factors. The greatest LEC mitogenic and sprouting response was observed for constant concentrations of VEGF-C and a high initial concentration that gradually decreased over time for VEGF-D. Additionally, alginate hydrogels provided sustained release of radiolabeled VEGF-C and VEGF-D. Finally, VEGF-C and VEGF-D released from these hydrogels promoted a similar number of LEC sprouts as exogenously added growth factors and new vasculature in vivo via a chick chorioallantoic membrane (CAM) assay. Overall, these findings demonstrate that alginate hydrogels can provide sustained and bio- active release of VEGF-C and VEGF-D which could have applications for therapeutic lymphangiogenesis.

description: Since the original work on Bose-Einstein condensation, quantum degenerate gases of atoms have allowed the quantum emulation of important systems from condensed matter and nuclear physics, as well as the study of novel many-body states with no analog in other fields of physics. Ultracold molecules in the micro- and nano-Kelvin regimes promise to bring powerful new capabilities to quantum emulation and quantum computing, thanks to their rich internal degrees of freedom compared to atoms. They also open new possibilities for precision measurement and the study of quantum chemistry. Quantum gases of atoms were made possible by collision-based cooling schemes, such as evaporative cooling. For ultracold molecules, thermalization and collisional cooling have not been realized. With other techniques such as supersonic jets and cryogenic buffer gases, studies have been limited to temperatures above 10 mK. Here we show cooling of NaLi molecules at micro- and nano-Kelvin temperatures through collisions with ultracold Na atoms, both prepared in their stretched hyperfine spin states. We find a lower bound on the elastic to inelastic collision ratio between molecules and atoms greater than 50 -- large enough to support sustained collisional cooling. By employing two stages of evaporation, we increase the phase-space density (PSD) of the molecules by a factor of 20, achieving temperatures as low as 220 nK. The favorable collisional properties of a Na and NaLi mixture show great promise for making deeply quantum degenerate dipolar molecules and suggest the potential for such cooling in other systems.

description: A self-consistent model of the chemical evolution of the globular cluster NGC 6752 is presented to test a popular theory that observed abundance anomalies are due to ``internal pollution'' from intermediate mass asymptotic giant branch stars. We simulated the chemical evolution of the intracluster medium under the assumption that the products of Type II SNe are completely expelled from the globular cluster, whereas material ejected from stars with m < 7 M_sun is retained, due to their weak stellar winds. By tracing the chemical evolution of the intracluster gas, we tested an internal pollution scenario in which the Na- and Al-enhanced ejecta from intermediate mass stars is either accreted onto the surfaces of other stars, or goes toward forming new stars. The observed spread in Na and Al was reproduced, but not the O-Na and Mg-Al anticorrelations. In particular, neither O nor Mg are sufficiently depleted to account for the observations. We predict that the Mg content of Na-rich cluster stars should be overwhelmingly dominated by the 25,26Mg isotopes, whereas the latest data shows only a mild 26Mg enhancement and no correlation with 25Mg. Furthermore, stars bearing the imprint of intermediate mass stellar ejecta are predicted to be strongly enhanced in both C and N, in conflict with the empirical data. We find that while standard AGB stellar models do show the hot H burning that seems required to explain the observations, this is accompanied by He burning, producing primary C, N, Mg and Na (via HBB) which do not match the observations.

description: Achieving the regime of single-photon nonlinearities in photonic devices just exploiting the intrinsic high-order susceptibilities of conventional materials would open the door to practical semiconductor-based quantum photonic technologies. Here we show that this regime can be achieved in a triply resonant integrated photonic device made of two coupled ring resonators, without necessarily requiring low volume confinement, in a material platform displaying an intrinsic third-order nonlinearity. By strongly driving one of the three resonances of the system, a weak coherent probe at one of the others results in a strongly suppressed two-photon probability at the output, evidenced by antibunched second-order correlation function at zero-time delay under continuous wave driving.

description: There is significant interest in the computational analysis of legal text to enhance search capabilities, to navigate the ever-growing corpus of electronic legal texts, and to aid in the application of artificial intelligence approaches to legal work and analysis. However, the feasibility of utilising this technique to trace the emergence and evolution of particular legal doctrines or substantive areas of law over time has not been achieved so far, despite the centrality of this task to legal practice and the use of legal text. Here, we report on the application of computational methods, including topic modelling and visualisation techniques, to measure the emergence and development of particular doctrines or areas of substantive law. We do so using two case studies, firstly the Mabo litigation regarding native title, and the rise and fall of 'proximity' as a test of foreseeability and the duty of care in tort.

description: We discuss the implementation of a directed geometrical worm algorithm for the study of quantum link-current models. In this algorithm Monte Carlo updates are made through the biased reptation of a worm through the lattice. A directed algorithm is an algorithm where, during the construction of the worm, the probability for erasing the immediately preceding part of the worm, when adding a new part,is minimal. We introduce a simple numerical procedure for minimizing this probability. The procedure only depends on appropriately defined local probabilities and should be generally applicable. Furthermore we show how correlation functions, C(r,tau) can be straightforwardly obtained from the probability of a worm to reach a site (r,tau) away from its starting point independent of whether or not a directed version of the algorithm is used. Detailed analytical proofs of the validity of the Monte Carlo algorithms are presented for both the directed and un-directed geometrical worm algorithms. Results for auto-correlation times and Green functions are presented for the quantum rotor model.

description: The Cosmic Bowel Hypothesis is a speculative, metaphorical model of the universe that reimagines black holes and white holes as parts of a vast cosmic digestive system.

In this framework:

Black holes act as the mouths of the universe, swallowing matter, energy, and information.

The singularity is the stomach—where everything gets compressed and processed.

Hawking radiation is interpreted as a thermodynamic burp—slow leakage of information.

White holes, rarely seen and poorly understood, are reframed as the reactive expulsions—the universe’s cosmic anus—releasing transformed energy and information under extreme pressure.

CBH humorously but thoughtfully explores ideas from gravitational thermodynamics, loop quantum gravity, and bounce cosmology, proposing that the Big Bang itself may have been a white hole event—a kind of “First Flush” from a previous universe.

Though satirical in tone, CBH offers a surprisingly coherent lens for thinking about entropy, information paradoxes, and cosmic recycling—all while embracing the very human urge to understand the universe through metaphors grounded in our own bodily experience.

description: The levitation forces between a permanent magnet and a coaxial superconducting disk after different magnetization processes are measured. Significant effect of the magnetization process on the levitation force is observed. Theoretical calculations of levitation force based on the critical state model with temperature and field-dependent critical current density, and the heat dissipation due to the flux motion are in perfect agreement with the experimental data.

description: In earlier work we proposed a generating function that encodes the Jordan block spectrum of the integrable Hypereclectic spin chain, related to the one-loop dilatation operator of the dynamical fishnet quantum field theory. We significantly improve the expressions for these generating functions, rendering them much more explicit and elegant. In particular, we treat the case of the full spin chain without imposing any cyclicity constraints on the states, as well as the case of cyclic states. The latter involves the Pólya enumeration theorem in conjunction with q-binomial coefficients.

description: We have conclusively established the duality between noncommutative Maxwell-Chern-Simons theory and Self-Dual model, the latter in ordinary spacetime, to the first non-trivial order in the noncommutativity parameter $θ^{μν}$, with $θ^{0i}=0$. This shows that the former theory is free for marginally noncommutative spacetimes. A $θ$-generalized covariant mapping between the variables of the two models in question has been derived explicitly, that converts one model to the other, including the symplectic structure and action.

description: We perform a calculation of Sivers function in a light-cone SU(6) quark-diquark model with both scalar diquark and vector diquark spectators. We derive the transverse momentum dependent light-cone wave function of the proton by taking into account the Melosh-Wigner rotation. By adopting one-gluon exchange, we obtain a non-vanishing Sivers function of $down$ quark from interference of proton spin amplitudes. We analyze the $\frac{|P_{h\perp}|}{M}$ weighted Sivers asymmetries in $π^+$, $π^-$ and $π^0$ electroproduction off transverse polarized proton target, averaged and not averaged by the kinematics of HERMES experiment.

Towards Electrical-Current Control of Quantum States in Spin-Orbit-Coupled Matter

description: Novel materials, which often exhibit surprising or even revolutionary physical properties, are necessary for critical advances in technologies. Simultaneous control of structural and physical properties via a small electrical current is of great significance both fundamentally and technologically. Recent studies demonstrate that a combination of strong spin-orbit interactions and a distorted crystal structure in magnetic Mott insulators is sufficient to attain this long-desired goal. In this Topical Review, we highlight underlying properties of this class of materials and present two representative antiferromagnetic Mott insulators, namely, 4d-electron based Ca2RuO4 and 5d-electron based Sr2IrO4, as model systems. In essence, a small, applied electrical current engages with the lattice, critically reducing structural distortions, which in turn readily suppresses the antiferromagnetic and insulating state and subsequently results in emergent new states. While details may vary in different materials, at the heart of these phenomena are current-reduced lattice distortions, which, via spin-orbit interactions, dictate physical properties. Electrical current, which joins magnetic field, electric field, pressure, light, etc. as a new external stimulus, provides a new, key dimension for materials research, and also pose a series of intriguing questions that may provide the impetus for advancing our understanding of spin-orbit-coupled matter. This Topical Review provides a brief introduction, a few hopefully informative examples and some general remarks. It is by no means an exhaustive report of the current state of studies on this topic.

The shifting identity of the subject : a psychoanalytic inquiry
Creators: name: Sarte, John
Publisher: name: The University of British Columbia

description: In this paper, I use psychoanalytic theory to re-consider the concept of identity. Using Lacanian psychoanalysis, I attempt to understand a subject’s shifting identity through the Imaginary, the Symbolic, and the Real. Thus, the subject’s identity (identification) becomes contingent on the ego, the big Other, intersubjectivity, and desire. I demonstrate how this psychoanalytic conception of identity can open up possibilities of inquiry into a teacher’s desire to learn. Some possible questions include: How are identity and desire related? In what ways can narratives be generated to study the desire to learn? Who is and what is the role of the research subject/researcher?

“If you could send over your documents to the photostat department...”: Paris Peace Conference Documentation and the Advent of Microfilm
Creators: Peter Binkley

In the years after 1919 the Paris Peace Conference and the Treaty of Versailles had enormous impact on world affairs, but historical research on the actual workings of the Conference was blocked, because the working documentation was in closed collections. A major opening came when David Hunter Miller self-published his 21-volume collection of Conference papers and allowed it to be distributed to research libraries by the Carnegie Endowment for International Peace in early 1929. The historian Robert C. Binkley schemed to use the Miller Diary to force the closed collections open. His first attempt was a collaboration with Parker Moon, based on sharing photostat copies of some rare documents as a supplement to Miller, in exchange for sharing of similar documents by the major collections. The idea seems to have fizzled, but the willingness of research libraries to participate committed them to more extensive sharing. Binkley then worked with James Shotwell on the Paris Peace Conference: History and Documents series, using microfilm instead of photostat. The microfilming campaign conducted by Robert and Frances Binkley at Yale and Columbia in January 1933 was sponsored by the Joint Committee on Materials for Research was an early trial and demonstration of the possibilities of large-scale microfilming in the American academic world.

description: Der Fokus der vorliegenden Arbeit liegt auf einer Analyse jener raumstrukturellen Einflussfaktoren, die wirtschaftlich bedeutsam sind. Neben der regionalen Wirtschaftsstruktur werden weitere ausgewählte harte und weiche Standortfaktoren untersucht. Diese beeinflussen einerseits Standortentscheidungen von Unternehmen und andererseits das subjektive Wohlbefinden der Bewohner der Lausitz. Die folgende Studie präsentiert diese Standortfaktoren in der größtmöglichen räumlichen Auflösung, die das zugängliche statistische Material zulässt. Die Lausitz gilt als eine sogenannte strukturschwache Region: ihre Wachstumsrate, ihr Beschäftigungsniveau und ihre Pro-Kopf-Produktivität sind im bundesdeutschen Vergleich unterdurchschnittlich. Eine detaillierte und räumlich differenzierte Betrachtung zeigt ein deutlich differenzierteres Bild. Die Lausitz ist keine „abgehängte Region“ sondern zeigt wie viele andere periphere Regionen Stärken und Schwächen, die räumlich sehr unterschiedlich verteilt sind.
description: The focus of this study is on an analysis of spatial-structural factors in a region that are economically significant. In addition to the regional economic structure, other selected hard and soft locational factors are examined. These factors influence the location decisions of companies on the one hand and the subjective well-being of the inhabitants of Lusatia on the other hand. The following study presents these locational factors in the highest possible spatial resolution that the available statistical data allow. Lusatia is classified as a so-called structurally weak region: its growth rate, employment level and per capita productivity are below average compared to the rest of Germany. But a detailed and spatially differentiated analysis draws a different picture. Lusatia is not a "backward region", but has strengths and weaknesses like many other peripheral regions that are very diversely distributed.
