description: New sensitive Very Large Array 20 cm continuum observations of the Cartwheel, the prototypical collisional ring galaxy, were carried out with the principal aim of tracing supernova remnants that are expected to lie in the wake of the expanding ring and in the ring itself. We detect predominantly non-thermal radio continuum emission from regions associated with 13 ring HII complexes. The emission interior to the ring is confined to structures that resemble spokes of the wheel. The spokes start near bright HII complexes, and extend to around 6 arcsec (4 kpc) inward in the direction of the geometrical center of the ring. There is no apparent positional coincidence between the radio continuum and optical spokes. Radial distribution of intensity along the spokes suggests that the past star formation rate (SFR) in the Cartwheel was much lower than the current SFR. New Halpha observations were used to revise the current SFR in the Cartwheel. The revised value is 18 Msun/yr, which is a factor of 4 lower than the value reported previously, but is in good agreement with the SFR estimated from far infrared luminosity. About 30% of the observed 20 cm continuum non-thermal emission seems to originate in processes that are not related to star formation. Revised SFR in the Cartwheel is comparable to that in the rest of the ring galaxies.

description: The evolution of the electron heat flux in the solar wind is regulated by the interplay between several effects: solar wind expansion, that can potentially drive velocity-space instabilties, turbulence and wave-particle interactions, and, possibly, collisions. Here we address the respective role played by the solar wind expansion and the electron firehose instability, developing in the presence of multiple electron populations, in regulating the heat flux. We carry out fully kinetic, Expanding Box Model simulations and separately analyze the enthalpy, bulk and velocity distribution function skewness contributions for each of the electron species. We observe that the key factor determining electron energy flux evolution is the reduction of the drift velocity of the electron populations in the rest frame of the solar wind. In our simulations, redistribution of the electron thermal energy from the parallel to the perpendicular direction after the onset of the electron firehose instability is observed. However, this process seems to impact energy flux evolution only minimally. Hence, reduction of the electron species drift velocity in the solar wind frame appears to directly correlate with efficiency for heat flux instabilities

description: During the course of last decade or so, there has been a significant surge of interest in developing processes and procedures that incorporate performance based concepts in design and evaluation of structural system, the findings and observations presented raise important issues that point to the need for additional research and the development and validation of methodologies that minimize uncertainty and maximize confidence. Beyond question, apart from many advantages, these methodologies have some shortcomings which need to be overcome. The primary focus of this study is to provide an analytical approach to develop the generalized seismic load patterns which the structures experience during different earthquakes at their highest demand levels and develop general forcing function which can be used as load patterns for seismic performance analysis of structures. A second emphasis has been given towards the performance evaluation of the existing structures presented herein. In this context, the need of retrofitting has to be discussed taking into account the interaction with masonry infill walls and seismic action types.

description: Estimates of price and scale demand elasticities for lamb and mutton consumed in the United States are derived. The U.S. lamb and mutton consumption comprises primarily of domestic production, and imports from two countries-Australia and New Zealand. The Netherlands Central Bureau of Statistics (CBS) demand system derived by Keller and Van Driel (1985) is employed. The CBS model is preferred as it combines non-linear Engel curves with the simplicity of the Slutsky matrix and allows for the ease of implementing concavity and other restrictions. Empirical results for own-price elasticities of demand indicate that U.S. demand for Australian lamb demand is highly elastic while U.S. demand for New Zealand and domestic lamb was inelastic. The scale demand elasticity results indicate that if the U.S. increases total demand for lamb, Australia and New Zealand's share of total demand will more than proportionately increase while the U.S. share of total demand will decrease. The scale elasticities show that domestic lamb is an inferior good.

description: In this work we study the $6j$ symbol of the $3d$ conformal group for fermionic operators. In particular, we study 4-point functions containing two fermions and two scalars and also those with four fermions. By using weight-shifting operators and harmonic analysis for the Euclidean conformal group, we relate these spinning $6j$ symbols to the simpler $6j$ symbol for four scalar operators. As one application we use these techniques to compute $3d$ mean field theory (MFT) OPE coefficients for fermionic operators. We then compute corrections to the MFT spectrum and couplings due to the inversion of a single operator, such as the stress tensor or a low-dimension scalar. These results are valid at finite spin and extend the perturbative large spin analysis to include non-perturbative effects in spin.

description: Gauge coupling unification and the success of TeV-scale weakly interacting dark matter are usually taken as evidence of low energy supersymmetry (SUSY). However, if we assume that the tuning of the higgs can be explained in some unnatural way, from environmental considerations for example, SUSY is no longer a necessary component of any Beyond the Standard Model theory. In this paper we study the minimal model with a dark matter candidate and gauge coupling unification. This consists of the SM plus fermions with the quantum numbers of SUSY higgsinos, and a singlet. It predicts thermal dark matter with a mass that can range from 100 GeV to around 2 TeV and generically gives rise to an electric dipole moment that is just beyond current experimental limits, with a large portion of its allowed parameter space accessible to next generation EDM and direct detection experiments. We study precision unification in this model by embedding it in a 5-D orbifold GUT where certain large threshold corrections are calculable, achieving gauge coupling and b-tau unification, and predicting a rate of proton decay just beyond current limits.

description: We study heavy quarkonium production associated with gluons in $\rm e^+e^-$ annihilation as an illustration of the perturbative QCD (pQCD) factorization approach, which incorporates the first nonleading power in the energy of the produced heavy quark pair. We show how the renormalization of the four-quark operators that define the heavy quark pair fragmentation functions using dimensional regularization induces "evanescent" operators that are absent in four dimensions. We derive closed forms for short-distance coefficients for quark pair production to next-to-leading order ($α_s^2$) in the relevant color singlet and octet channels. Using non-relativistic QCD (NRQCD) to calculate the heavy quark pair fragmentation functions up to $v^4$ in the velocity expansion, we derive analytical results for the differential energy fraction distribution of the heavy quarkonium. Calculations for ${}^3S_1^{[1]}$ and ${}^1S_0^{[8]}$ channels agree with analogous NRQCD analytical results available in the literature, while several color-octet calculations of energy fraction distributions are new. We show that the remaining corrections due to the heavy quark mass fall off rapidly in the energy of the produced state. To explore the importance of evolution at energies much larger than the mass of the heavy quark, we solve the renormalization group equation perturbatively to two-loop order for the ${}^3S_1^{[1]}$ case.

description: The statistical properties of the ultra-luminous X-ray source (ULX) populations extracted from the ROSAT HRI survey of X-ray point sources in nearby galaxies in Paper I are studied to reveal connections between the ULX phenomenon and survey galaxy properties. The $logN$--$logS$ relation is used to calculate and remove the influence of false ULXs from the background and/or foreground objects. Study of the luminosity functions shows that the regular ULXs below $10^{40}$ erg/sec are an extension of the ordinary HMXB/LMXB population below $10^{39}$ erg/sec in the late-type galaxies, and that the extreme ULXs above $10^{40}$ erg/sec might be a different population from the regular ULXs. This survey confirms statistically that the ULX phenomenon is closely connected to star formation activities, since ULXs preferentially occur in late-type galaxies rather than in early-typTwo ULX populations, the HMXB-like ULXs as an extension of the ordinary HMXB population associated with the young stellar population and the LMXB-like ULXs as an extension of the ordinary LMXB population associated with the old stellar population, are both required to account for the total ULX population. It is found that the LMXB-like ULXs dominate the ULX population at low star formation rates, while HMXB-like ULXs dominate at high star formation rates. However, an accurate quantitative description of the relative fractions of HMXB-like ULXs and LMXB-like ULXs is impossible in the current HRI survey due to the source blending effects, and a Chandra survey of the X-ray point sources in nearby galaxies would be required for this purpose. e galaxies, and ULXs in late-type galaxies tend to trace the spiral arms.

description: The white dwarf SDSS J124043.01+671034.68 (SDSS J1240+6710) was previously found to have an oxygen-dominated atmosphere with significant traces of neon, magnesium, and silicon. A possible origin via a violent late thermal pulse or binary interactions have been suggested to explain this very unusual photospheric composition. We report the additional detection of carbon, sodium, and aluminium in far-ultraviolet and optical follow-up spectroscopy. No iron-group elements are detected, with tight upper limits on iron, cobalt and nickel, suggesting that the star underwent partial oxygen burning, but failed to ignite silicon burning. Modelling the spectral energy distribution and adopting the distance based on the Gaia parallax, we infer a low white dwarf mass, M(wd)=0.41+/-0.05Msun. The large space velocity of SDSS J1240+6710, computed from the Gaia proper motion and its radial velocity, is compatible with a Galactic rest-frame velocity of ~250km/s in the opposite direction with respect to the Galactic rotation, strongly supporting a binary origin of this star. We discuss the properties of SDSS J1240+6710 in the context of the recently identified survivors of thermonuclear supernovae, the D6 and LP 40-365 stars, and conclude that it is unlikely related to either of those two groups. We tentatively suggest that SDSS J1240+6710 is the partially burned remnant of a low-mass white dwarf that underwent a thermonuclear event.

description: We evaluate the persistence of incremental industry, firm-specific, and corporate-parent effects on firm profitability across the food and agribusiness sector and further analyze the persistence within four major sectors: processing, wholesale, retail, and restaurant. Results suggest that industry effects are more persistent than corporate effects across the food and agribusiness sector. Results also suggest the retail supermarket sector has had relatively stable profits due to both industry and firm effects during the time period under study. The results have implications with respect to research and extension programs targeted toward educating producers and management about producer-owned businesses.

description: Pressure-induced phase transitions in orthovanadates have led to interesting physical phenomena. The observed transitions usually involve large volume collapses and drastic changes in the electronic and vibrational properties of the materials. In some cases, the phase transitions implicate coordination changes in vanadium, which has important consequences in the physical properties of vanadates. In this Perspective, we explore the current knowledge of the behavior of MVO4 vanadates under compression. In particular, we summarize studies of the structural, vibrational, and electronic properties and a few illustrative examples of high-pressure research in the compounds of interest are discussed. A systematic understanding of the high-pressure behavior of MVO4 compounds is presented, putting the emphasis on results that could be relevant for practical applications. Recent advances and future challenges in the study of orthovanadates under extreme pressure will be reviewed, along with conclusions that could have consequences for the studies of related oxides. Some ideas on topics that may lead to exciting breakthroughs in the near future will be presented too.

description: We have conducted a combined observational and theoretical investigation of the ubiquitous knots in the Helix Nebula (NGC 7293). We have constructed a combined hydrodynamic+radiation model for the ionized portion of these knots and have accurately calculated a static model for their molecular regions. Imaging observations in optical emission lines were made with the Hubble Space Telescope's STIS spectrograph, operating in a "slitless" mode, complemented by WFPC2 images in several of the same lines. The NICMOS camera was used to image the knots in molecular hydrogen. These observations, when combined with other studies of molecular hydrogen and CO provide a complete characterization of the knots. They possess dense molecular cores of densities about 1,000,000 per cubic centimeter surrounded on the central star side by a zone of hot molecular hydrogen. The temperature of the molecular hydrogen emitting layer defies explanation either through detailed calculations for radiative equilibrium or for simplistic calculations for shock excitation. Further away from the core is the ionized zone, whose peculiar distribution of emission lines is explained by the expansion effects of material flowing through this region. The shadowed region behind the core is the source of most of the CO emission from the knot and is of the low temperature expected for a radiatively heated molecular region.

description: Binary interaction can cause stellar envelopes to be stripped, which significantly reduces the radius of the star. The orbit of a binary composed of a stripped star and a compact object can therefore be so tight that the gravitational radiation the system produces reaches frequencies accessible to the Laser Interferometer Space Antenna (LISA). Two such stripped stars in tight orbits with white dwarfs are known so far (ZTF J2130+4420 and CD-30 11223), but many more are expected to exist. These binaries provide important constraints for binary evolution models and may be used as LISA verification sources. We develop a Monte Carlo code that uses detailed evolutionary models to simulate the Galactic population of stripped stars in tight orbits with either neutron star or white dwarf companions. We predict 0-100 stripped star + white dwarf binaries and 0-4 stripped star + neutron star binaries with SNR>5 after 10 years of observations with LISA. More than 90% of these binaries are expected to show large radial velocity shifts of $\gtrsim 200$ km/s, which are spectroscopically detectable. Photometric variability due to tidal deformation of the stripped star is also expected and has been observed in ZTF J2130+4420 and CD-30 11223. In addition, the stripped star + neutron star binaries are expected to be X-ray bright with $L_X \gtrsim 10^{33} - 10^{36}$ erg/s. Our results show that stripped star binaries are promising multi-messenger sources for the upcoming electromagnetic and gravitational wave facilities.

description: An ensemble of multilevel atoms is a good candidate for a quantum information storage device. The information is encrypted in the collective ground state atomic coherence, which, in the absence of external excitation, is decoupled from the vacuum and therefore decoherence free. However, in the process of manipulation of atoms with light pulses (writing, reading), one inadvertently introduces a coupling to the environment, i.e. a source of decoherence. The dissipation process is often treated as an independent process for each atom in the ensemble, an approach which fails at large atomic optical depths where cooperative effects must be taken into account. In this paper, the cooperative behavior of spin decoherence and population transfer for a system of two, driven multilevel-atoms is studied. Not surprisingly, an enhancement in the decoherence rate is found, when the atoms are separated by a distance that is small compared to an optical wavelength; however, it is found that this rate increases even further for somewhat larger separations for atoms aligned along the direction of the driving field's propagation vector. A treatment of the cooperative modification of optical pumping rates and an effect of polarization swapping between atoms is also discussed, lending additional insight into the origin of the collective decay.

This research is particularly relevant to Sub-Saharan Africa given the dramatic reduction in life expectancy due to HIV/AIDS and the potential lasting effects on growth. Our results indicate that as life expectancy shortens so does schooling inducing a lower growth rate of income. These relationships are even more pronounced for the African continent than for the rest of the world.

Die Messungen wurden jeweils mit dem Benkelmannbalken und dem Falling-Weight-Deflectometer vorgenommen. Beide Verfahren unterscheiden sich durch die Art der Lateintragung. Die Lasteintragung erfolgt mit dem Benkelmannbalken statisch und mit dem Falling-Weight-Deflectometer dynamisch. Daraus folgt, dass die aus den Einsenkungswerten ermittelten E-Module mittels Benkelmannbalken statische E-Module und mittels Falling-Weight-Deflectometer. dynamische E-Module sind. Der E-Modul einer Schicht ist ein Maß für den Verformungswiderstand einer Straßenkonstruktion. Jede Straßenkonstruktion weist ein kompliziertes Verformungsverhalten auf. Betonstraßen besitzen in der Regel größere E-Module als Asphaltstraßen, die sich aber viskoelastisch und viskoplastisch verformen können. Der E-Modul einer Schicht ist auch von der jeweiligen Schichthöhe abhängig. Grundsätzlich gilt, je mehr Einsenkungswerte von einer Straßenkonstruktion zur Verfügung stehen, desto genauer fallen die Beurteilungen hinsichtlich ihrer Tragfähigkeit aus. Die mathematische Ermittlung der Tragfähigkeit einer Straßenkonstruktion erfolgt über die Festlegung eines mathematischen Modells. Es wurden verschiedene Modelle untersucht. Das einfachste Modell zur Beschreibung einer Straßenkonstruktion ist der elastisch- isotrope Halbraum, wobei der gesamte Straßenkörper durch einen einzigen E-Modul beschrieben wird. Eine wesentlich exaktere Beschreibung einer Straßenkonstruktion ist das Zweischichtensystem. In diesem System wird der bituminöse Aufbau mit der Schichtdicke h und dem E-Modul E1 gekennzeichnet und die Unterlage (Frostschutzschicht und Untergrund zusammengefasst) mit dem E-Modul E2 beschrieben. Das Zweischichtensystem hat den Vorteil, dass ein erkennbarer E-Modul Sprung zwischen der gebundenen Schicht (E1) und der ungebundnen Schicht (E2) entsteht. Ein drei oder mehrschichtiges System hier anzuwenden ist sehr schwierig, da dieses nicht eindeutig bestimmt ist. Das Zweischichtensystem ist eindeutig bestimmt und liefert genügend gute Ergebnisse, um die Tragfähigkeit zu beschreiben.

description: Work function-mediated charge transfer in graphene/$α$-RuCl$_3$ heterostructures has been proposed as a strategy for generating highly-doped 2D interfaces. In this geometry, graphene should become sufficiently doped to host surface and edge plasmon-polaritons (SPPs and EPPs, respectively). Characterization of the SPP and EPP behavior as a function of frequency and temperature can be used to simultaneously probe the magnitude of interlayer charge transfer while extracting the optical response of the interfacial doped $α$-RuCl$_3$. We accomplish this using scanning near-field optical microscopy (SNOM) in conjunction with first-principles DFT calculations. This reveals massive interlayer charge transfer (2.7 $\times$ 10$^{13}$ cm$^{-2}$) and enhanced optical conductivity in $α$-RuCl$_3$ as a result of significant electron doping. Our results provide a general strategy for generating highly-doped plasmonic interfaces in the 2D limit in a scanning probe-accessible geometry without need of an electrostatic gate.

description: Bei der grundbautechnischen Bemessung und der Errichtung von Bauwerken im Grundwasser sind die wesentlichen Einwirkungen auf hydrodynamische Effekte zurückzuführen. Die zu-verlässige Funktion eines solchen Bauwerkes ist maßgeblich von der richtigen Einschätzung der unterschiedlichen Effekte abhängig. Aufgabe ist es, hydraulisch bedingte Versagensformen wie Hydraulischer Grundbruch, innere Erosion, Aufschwimmen und Auftrieb zu charakterisieren und voneinander abzugrenzen, ty-pische Beispiele dieser Versagensformen zu nennen, Interaktionen zwischen ihnen aufzu-zeichnen und zu quantifizieren sowie Einflussparameter und Grenzzustände zu beschreiben. Aufbauend auf diesen Betrachtungen soll am praktischen Beispiel einer Baugrubensicherung durch konventionelle Rechnung und numerische Simulation das Versagensprinzip des Hyd-raulischen Grundbruches in nicht bindigem Boden nachvollzogen werden. Die Ergebnisse der Analyse sind unter dem Gesichtspunkt der Richtigkeit der zugrunde liegenden physikalischen Gesetzmäßigkeiten zu bewerten.

description: We construct a class of symplectic non--Kaehler and complex non--Kaehler string theory vacua, extending and providing evidence for an earlier suggestion by Polchinski and Strominger. The class admits a mirror pairing by construction. Comparing hints from a variety of sources, including ten--dimensional supergravity and KK reduction on SU(3)--structure manifolds, suggests a picture in which string theory extends Reid's fantasy to connect classes of both complex non-Kaehler and symplectic non-Kaehler manifolds.

description: Blended Learning, which gained prominence, especially after the COVID-19 pandemic, emphasized improving student learning, autonomy, and engagement. This research has a qualitative nature, based on a Systematic Literature Review, as a result of questioning the contribution of Hybrid Learning to student autonomy and engagement. Grouping and identification of five types of hybrid learning were carried out. Next, a taxonomic categorization was proposed for each blended learning cluster. The objective of this work was to propose five conceptual frameworks for Hybrid Learning to contribute to the work of teachers in applying them since teachers are fundamental in evaluating the educational tools available and choosing the correct hybrid teaching approach. This study aims to support future research on the implementation of hybrid teaching in Brazil.

description: The performance of over 530 North Dakota farms, 1997-1999, is summarized using 16 financial measures. Farms are categorized by geographic region, farm type, farm size, gross cash sales, farm tenure, net farm income, debt-to-asset, and age of farmer to analyze relationships between financial performance and farm characteristics. Farm financial trends for the 1991-1999 period are also presented. Financial performance in 1999 was the best since 1993, and had great improvement from 1997 and 1998 when one-fourth of farms had negative net farm income and over one-half of farms were not able to make scheduled term debt payments with the year's income. Although crop prices were low in 1999, there was extraordinary government and crop insurance payments, and improved beef cattle prices. Median net farm income was 42,009 in 1999, $19,491 in 1998 and $14,290 in 1997.

description: In the field of frustrated magnetism, Kitaev models provide a unique framework to study the phenomena of spin fractionalization and emergent lattice gauge theories in two and three spatial dimensions. Their ground states are quantum spin liquids, which can typically be described in terms of a Majorana band structure and an ordering of the underlying $\mathbb{Z}_2$ gauge structure. Here we provide a comprehensive classification of the "gauge physics" of a family of elementary three-dimensional Kitaev models, discussing how their thermodynamics and ground state order depends on the underlying lattice geometry. Using large-scale, sign-free quantum Monte Carlo simulations we show that the ground-state gauge order can generally be understood in terms of the length of elementary plaquettes -- a result which extends the applicability of Lieb's theorem to lattice geometries beyond its original scope. At finite temperatures, the proliferation of (gapped) vison excitations destroys the gauge order at a critical temperature scale, which we show to correlate with the size of vison gap for the family of three-dimensional Kitaev models. We also discuss two notable exceptions where the lattice structure gives rise to "gauge frustration" or intertwines the gauge ordering with time-reversal symmetry breaking. In a more general context, the thermodynamic gauge transitions in such 3D Kitaev models are one of the most natural settings for phase transitions beyond the standard Landau-Ginzburg-Wilson paradigm.

description: The value of credit guarantee programs has recently been called into question. Credit guarantees are important marketing tools in the world wheat market, both to develop new markets and to compete in existing markets. This study examines the additionality of export credit guarantees. Empirical demand models were developed and estimated using pooled data among importing countries. Models were estimated for each of the principal exporting countries providing export credit guarantees: the United States, Canada and France. Additionality of credit guarantees were also contrasted to the Export Enhancement Program. Positive additionality was found for CCC guarantees, indicating that the GSM programs have resulted in additional exports that would not have occurred without the programs. Additionality was not constant across exporters. Additionality was estimated at 12.6 MMT for credit guarantees and 19 MMT for EEP. The U.S. results, when considering costs of the programs, indicate that the CCC subsidy (from guarantees), on a per dollar of subsidy basis, provides about four times more additionality than EEP. These results cast doubt on the price subsidy equivalence of guarantees. The subsidy implied in Canadian credit has a significant and negative effect on U.S. wheat exports. The magnitude of the coefficient is larger than the magnitude of the CCC guarantee subsidy. In the Canadian demand model, the effect of the CCC subsidy is insignificant. The results suggest that Canada's guarantee program does more to displace U.S. sales than it does to help Canadian sales. Further, as a whole CCC guarantees offset Canadian guarantees and outperform COFACE guarantees.
