description: We have carried out calculations of ionization equilibrium and deuterium fractionation for conditions appropriate to a completely depleted, low mass pre--protostellar core, where heavy elements such as C, N, and O have vanished from the gas phase and are incorporated in ice mantles frozen on dust grain surfaces. We put particular emphasis on the interpretation of recent observations of H2D+ towards the centre of the prestellar core L1544 (Caselli et al. 2003) and also compute the ambipolar diffusion timescale. We consider explicitly the ortho and para forms of H2,H3+, and H2D+. Our results show that the ionization degree under such conditions depends sensitively on the grain size distribution or, more precisely, on the mean grain surface area per hydrogen nucleus. Depending upon this parameter and upon density, the major ion may be H+, H3+, or D3+. We show that the abundance of ortho-H2D+ observed towards L1544 can be explained satisfactorily in terms of a complete depletion model and that this species is, as a consequence, an important tracer of the kinematics of prestellar cores.

Low frequency and Microwave Magnetoelectric Effects in Thick Film Heterostructures of Lithium Zinc Ferrite and Lead Zirconate Titanate

description: Magnetoelectric (ME) coupling at low frequencies and at x-band have been investigated in layered samples containing zinc substituted lithium ferrite and lead zirconate titanate (PZT). Multilayers of Li0.5-x/2ZnxFe2.5-x/2O4 (LZFO) (x=0-0.4) and PZT were prepared by lamination and sintering of thick films. At low frequencies (10-1000 Hz), the ME voltage coefficient for transverse fields is higher than for longitudinal fields. With Zn substitution in the ferrite, transverse coupling increases to a maximum for x=0.3 and then decreases for higher x. Analysis based on our model for a bilayer implies an efficient magneto-mechanical coupling with Zn substitution, resulting in strong ME interactions. Microwave ME coupling is studied through measurements of shift in the ferromagnetic resonance field due to an applied electric field. Estimated ME constants from such data are in agreement with our model for a ferrite-PZT bilayer.

description: In order to investigate the importance of different proposed quenching mechanisms, we use an indirect method to estimate gas masses for ~62,000 SDSS DR7 galaxies. We infer gas surface densities from dust column densities as traced by extinction within the fibre, applying a metallicity correction to account for varying dust-to-gas ratios. We find that both gas fraction and star formation efficiency (SFE) decrease moving away from the star forming main sequence (MS) towards quiescence for all galaxy masses. We further show that both quantities correlate similarly strongly with the departure from the MS, implying the need for any physical model of quenching to invoke a change in $\textit{both}$ gas fraction and SFE. Our results call for a better understanding of the physical processes driving the decrease in star formation efficiency, which has received relatively little attention in the theory of quenching until now.

 The eastern Southern Alps formed as a retro-wedge of the Alpine orogen and shortening is partitioned into three kinematically linked fold-and-fault systems: (1) the Giudicarie Bel; (2) the Valsugana Thrust System; and (3) the external orogenic front, including the strike-slip Schio-Vicenza Fault. Here, we present closely spaced geological cross-sections from the Northern Giudicarie Fault to the South Alpine orogenic front to assess the amount of Neogene shortening and better understand deformation of the Adriatic indenter in Mio-Pliocene time. The amount of Neogene, NNW-SSE shortening varies from 8 km in the vicinity of the Adige embayment to 25 km further to the northeast, with most shortening (18-22 km) accommodated within the Giudicarie Belt and Valsugana Thrust System. Shortening estimates vary on either side of the Trento-Cles, Schio-Vicenza and Ballino-Garda strike-slip faults. These faults coincide with major Permian-Mesozoic paleogeographic boundaries across which the stratigraphic thickness and rheological properties of rock units significantly change. We interpret these to be responsible for strain partitioning in the eastern Southern Alps. Moreover, balancing and forward modelling of the cross-sections with MOVE Suite Software indicate that the depth of the detachments within the Pre-Permian basement is no greater than 20km. The Northern Giudicarie Fault has recorded 75 km of Neogene sinistral offset, of which 40 km was accommodated by shortening along the Val Trompia fold-and-thrust belt and 35 km by shortening along the Giudicarie/Valsugana domain east of the Trento-Cles Fault. Additional Neogene shortening may have occurred within a decoupled lower crustal Adriatic wedge beneath the Tauern Window.

Laboratory assessments included hematological, biochemical, and inflammatory markers. Multivariable analysis identified age (OR = 1.56, p = 0.004), chemotherapy cycles (OR = 1.86, p < 0.001), comorbidities (OR = 3.15, p = 0.015), WBC count (OR = 1.79, p = 0.016), CRP (OR = 2.07, p = 0.007), ferritin (OR = 1.22, p = 0.035), IL-6 (OR = 1.59, p = 0.001), IgG (OR = 2.28, p = 0.037), CD8+ T cells (OR = 2.97, p = 0.005), and NK cells (OR = 0.80, p = 0.019) as COVID-19 risk factors. COVID-19 patients showed significantly higher hospitalization (30.77% vs 10.42%, p = 0.007), ICU admission (23.08% vs 6.25%, p = 0.019), and lower 1-year survival (59.62% vs 87.50%, p = 0.002) versus controls. SARS-CoV-2 infection induces hematological/immune alterations and worsens clinical outcomes in hematological malignancy patients, emphasizing their heightened vulnerability.

description: We investigate the systematics of fission barriers in superheavy elements in the range Z = 108-120 and N = 166-182. Results from two self-consistent models for nuclear structure, the relativistic mean-field (RMF) model as well as the non-relativistic Skyrme-Hartree-Fock approach are compared and discussed. We restrict ourselves to axially symmetric shapes, which provides an upper bound on static fission barriers. We benchmark the predictive power of the models examining the barriers and fission isomers of selected heavy actinide nuclei for which data are available. For both actinides and superheavy nuclei, the RMF model systematically predicts lower barriers than most Skyrme interactions. In particular the fission isomers are predicted too low by the RMF, which casts some doubt on recent predictions about superdeformed ground states of some superheavy nuclei. For the superheavy nuclei under investigation, fission barriers drop to small values around Z = 110, N = 180 and increase again for heavier systems. For most of the forces, there is no fission isomer for superheavy nuclei, as superdeformed states are in most cases found to be unstable with respect to octupole distortions.

description: We study several geometric and group theoretical problems related to Kodaira fibrations, to more general families of Riemann surfaces, and to surface-by-surface groups. First we provide constraints on Kodaira fibrations that fiber in more than two distinct ways, addressing a question by Catanese and Salter about their existence. Then we show that if the fundamental group of a surface bundle over a surface is a ${\rm CAT}(0)$ group, the bundle must have injective monodromy (unless the monodromy has finite image). Finally, given a family of closed Riemann surfaces (of genus $\ge 2$) with injective monodromy $E\to B$ over a manifold $B$, we explain how to build a new family of Riemann surfaces with injective monodromy whose base is a finite cover of the total space $E$ and whose fibers have higher genus. We apply our construction to prove that the mapping class group of a once punctured surface virtually admits injective and irreducible morphisms into the mapping class group of a closed surface of higher genus.

Gas accretion as fuel for residual star formation in Galaxy Zoo elliptical galaxies
Creators: name: Davis, Timothy A.

Publisher: name: arXiv
Year: 2019
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: In this letter we construct a large sample of early-type galaxies with measured gas-phase metallicities from the Sloan Digital Sky Survey and Galaxy Zoo in order to investigate the origin of the gas that fuels their residual star formation. We use this sample to show that star forming elliptical galaxies have a substantially different gas-phase metallicity distribution from spiral galaxies, with ~7.4% having a very low gas-phase metallicity for their mass. These systems typically have fewer metals in the gas phase than they do in their stellar photospheres, which strongly suggests that the material fuelling their recent star formation was accreted from an external source. We use a chemical evolution model to show that the enrichment timescale for low-metallicity gas is very short, and thus that cosmological accretion and minor mergers are likely to supply the gas in >37% of star-forming ETGs, in good agreement with estimates derived from other independent techniques.

Atmospheric parameters and abundances of sdB stars

description: We summarize recent results of quantitative spectral analyses using NLTE and metal line-blanketed LTE model atmospheres. Temperatures and gravities derived for hundreds of sdB stars are now available and allow us to investigate systematic uncertainties of teff, log g scales and to test the theory of stellar evolution and pulsations. Surface abundance patterns of about two dozen sdB stars are surprisingly homogenous. In particular the iron abundance is almost solar for most sdBs. We highlight one iron deficient and three super metal-rich sdBs, a challenge to diffusion theory. SdB stars are slowly rotating stars unless they are in close binary systems which is hard to understand if the sdB stars were formed in merger events. The only exception is the pulsator PG 1605+072 rotating at v sin i = 39km/s. Signatures of stellar winds from sdB stars have possibly been found.

description: Self-transcribing active regulatory region sequencing (STARR-seq) was first described in 2013 by Arnold et al. and allows to identify and quantify enhancer regions in non-coding DNA in large scale. The R-package BasicSTARRseq provides routines for quality controls, analysis and visualization of STARR-seq data. The analysis part is mainly covered through the implementation of the computational procedure to call peaks i. e. identify possible enhancers, which was introduced in the above mentioned article. The peak calling is based on comparing sample data with input data of the STARR-seq experiment and computes p-values to estimate the peaks' reliability. By including user chosen parameters, for example two alternative binomial models for calculating the p-value, peak calling can be adjusted to different kinds of data. The procedure can further be adapted to whole-genome or targeted sequencing. Resulting peaks are annotated to allow an easy overview over the results or for further filtering steps. Quality controls and visualization are offered by routines for comparing different replicates, and the comparison of experiment data and target regions. For plausibility checks or further explorative analysis the package also provides some functions to compare output tracks of other analysis (like peak lists of Chip-seq data, but also other data chosen by the user) with STARR-seq data. BacisSTARRseq includes test datasets extracted from the published data of Arnold et al.

description: Graphite surfaces interact weakly with molecules compared to other conducting surfaces bringing the molecule-molecule interaction to the foreground. C$_{60}$ on highly oriented pyrolytic graphite is a model system for studying the molecular self-assembly on surfaces. Our scanning tunneling microscopy measurements at liquid nitrogen temperatures confirm the previously observed island growth mode. Our results indicate that there is an epitaxial relationship of the molecular islands and the substrate with three possible orientations of the islands. For one of these orientations, we determine this epitaxial relationship by analyzing in detail an image taken across a C$_{60}$ island step edge. In this image we have obtained high resolution on both the molecular island and the substrate. The result of this analysis is confirmed by two-dimensional Fourier analysis.

We observe that loading a magneto-optical trap (MOT) from a continuous and intense flux of slowed atoms and by appropriately tuning the frequency of the repumper laser is possible to achieve basically the same effect of the dark SPOT, using a simpler apparatus. This work characterizes the new system through measurements of absorption and fluorescence imaging of the atomic cloud and presents a very simple model to explain the main features of our observations. We believe that this new approach may simplify the current experiments to produce quantum degenerated gases.

description: Forest farmers are the basic micro-subjects in southern collectively owned forest, and their willingness towards forest management directly influences forestry development. Thus, to provide subsidies to forest farmers is an important means to encourage the farmers' enthusiasm to manage the forest and promote the healthy and sustainable development of private forest. In order to reduce the supply-demand contradictions and improve the implementation effects of the subsidies system, the design of the system should be based on the real needs of forest farmers. On this basis, a questionnaire survey was designed in this paper to study the preferences of forest farmers to different types of subsidies in the southern collectively owned forest and the influencing factors were analysed by the Logistic Model to search for the reasonable design of the system. It was concluded that the forest farmers with different backgrounds show different preference to the subsidies, which, to a certain extent, reflects the development bottlenecks of forestry, and lays a foundation for the design of subsidies system.

description: In the classical operator theory, there are several versions of spectra, related to special classes of operators (Fredholm, semi-Fredholm, upper/lower semi-Fredholm,etc.). We generalize these notions for adjointable operators on Hilbert C*-modules replacing scalars by the center of the algebra, and show that most relations between these spectra are still true for these generalized versions. The relation between these spectra of an operator and those of its compressions is also transferred to the case of Hilbert C*-modules.

Then we prove the equivalence between the category of continuous modules of $\Ext ^{\sharp}_{G ^{\vee}} X (χ)$ and the category of unramified admissible modules of $G (\mathbb K)$ with a generalized infinitesimal character corresponding to $χ$. This is an analogue of Soergel's conjecture which concerns the real reductive setting.

description: Decoherence of massive body wave function under Continuous Spontaneous Localization is reconsidered. It is shown for homogeneous probes with wave functions narrow in position and angle that decoherence is a surface effect. Corresponding new surface integrals are derived as the main result. Probe's constant density and two completely geometric surface-dependent invariant tensors encode full dependence of positional and angular decoherence of masses, irrespective of their microscopic structure. The two surface-tensors offer a new insight into CSL and a flexible approach to design laboratory test masses.

description: Josephson junctions are the basis for the most sensitive magnetic flux detectors, the definition of the unit volt by the Josephson voltage standard, and superconducting digital and quantum computing. They result from the coupling of two coherent quantum states, as they occur in superconductors, superfluids, atomic Bose-Einstein condensates, and exciton-polariton condensates. In their ground state, Josephson junctions are characterised by an intrinsic phase jump. Controlling this phase jump is fundamental for applications in computing. Here, we experimentally demonstrate controllable phase relations between photon Bose-Einstein condensates resulting from particle exchange in a thermo-optically tunable potential landscape. Our experiment realises an optical analogue of a controllable 0,$π$-Josephson junction. By connecting several junctions, we can study a reconfigurable 4-condensate system demonstrating the potential of our approach for analog spin glass simulation. More generally, the combination of static and dynamic nanostructuring techniques introduced in our work offers a powerful platform for the implementation of adaptive optical systems for paraxial light in and outside of thermal equilibrium.

description: The effective interaction between electrons in two-dimensional materials can be modified by their environment, enabling control of electronic correlations and phases. Here, we study the dependence of electronic correlations in twisted bilayer graphene (tBLG) on the separation to the metallic gate(s) in two device configurations. Using an atomistic tight-binding model, we determine the Hubbard parameters of the flat bands as a function of gate separation, taking into account the screening from the metallic gate(s), the dielectric spacer layers and the tBLG itself. We determine the critical gate separation at which the Hubbard parameters become smaller than the critical value required for a transition from a correlated insulator state to a (semi-)metallic phase. We show how this critical gate separation depends on twist angle, doping and the device configuration. These calculations may help rationalise the reported differences between recent measurements of tBLG's phase diagram and suggests that correlated insulator states can be screened out in devices with thin dielectric layers.

description: In this paper we study the connection between the phenomenon of homological percolation (the formation of "giant" cycles in persistent homology), and the zeros of the expected Euler characteristic curve. We perform an experimental study that covers four different models: site-percolation on the cubical and permutahedral lattices, the Poisson-Boolean model, and Gaussian random fields. All the models are generated on the flat torus $T^d$, for $d=2,3,4$. The simulation results strongly indicate that the zeros of the expected Euler characteristic curve approximate the critical values for homological-percolation. Our results also provide some insight about the approximation error. Further study of this connection could have powerful implications both in the study of percolation theory, and in the field of Topological Data Analysis.

description: We investigate the effects of previous fertilizer subsidy program on local grain prices in Nigeria. The program has been considered ineffective in targeting and stimulating demand for fertilizer, with potentially rampant leakages. If the program has reduced food price, however, it can still be partly justified regardless of targeting efficiency. We exploit the panel structure of Living Standard Measurement Survey – Integrated Survey on Agriculture (LSMS) collected in 2010 post-planting season and 2011 post-harvesting season. Our methods use Euclidian distance between each district and state governors’ origin district in each state to identify fertilizer subsidy distribution. We also use proxy variable that accounts for both direct subsidy provision and indirect leakage effects to measure the effective size of subsidy. Fertilizer subsidy generally had no effect on maize and sorghum price. In northern Nigeria, fertilizer subsidy might have lowered district level price of local rice, but only to a limited extent. Low market orientation of many subsidy recipients, crowding out of commercial fertilizer, and political influence in subsidy allocations may explain such low impact. We also discuss how our methods minimize potential biases due to errors-in-variable and sample selection.

The Spatial Structure of Farmland Values: A Semiparametric Approach

Year: 2013
Subjects: Land Economics/Use

description: Although accounting for the spatial - temporal relationships in farmland valuation has gained attention in the literature recently, misspecification and incorrectly imposed assumptions on spatial weighting matrix can often produce misleading estimates and inference compared to maintaining ignorance of spatial dependence structure among spatially observed farmland values. In this study I assemble a panel data set using Pennsylvania county level farmland values reported in the U.S. Census of Agriculture between 1982 and 2007, and estimate the spatial weighting matrix among farmland values semiparametrically. A spatial lag panel data model with the consistently estimated spatial weighting matrix is then estimated via maximum likelihood estimation (MLE). The results show that the proposed approach can substantially improve the goodness of fit of the spatial hedonic model of farmland values therefore the reliability of obtained price elasticity estimates.

Chandra Observation of the Edge-on Galaxy NGC 3556 (M 108): Violent Galactic Disk-halo Interaction Revealed

description: We present a 60 ks Chandra ACIS-S observation of the isolated edge-on spiral NGC 3556, together with a multiwavelength analysis of various discrete X-ray sources and diffuse X-ray features. Among 33 discrete X-ray sources detected within the I_B = 25 mag per square arcsec isophote ellipse of the galaxy, we identify a candidate for the galactic nucleus, an ultraluminous X-ray source that might be an accreting intermediate-mass black hole, a possible X-ray binary with a radio counterpart, and two radio-bright giant HII regions. We detect large amounts of extraplanar diffuse X-ray emission, which extends about 10 kpc radially in the disk and >~ 4 kpc away from the galactic plane. The diffuse X-ray emission exhibits significant substructures, possibly representing various blown-out superbubbles or chimneys of hot gas heated in massive star forming regions. This X-ray-emitting gas has temperatures in the range of ~ 2-7 x 10^6 K and has a total cooling rate of ~ 2 x 10^40 erg/s. The energy can be easily supplied by supernova blast-waves in the galaxy. These results demonstrate NGC 3556 as being a galaxy undergoing vigorous disk-halo interaction. The halo in NGC 3556 is considerably less extended, however, than that of NGC 4631, in spite of many similarities between the two galaxies. This may be due to the fact that NGC 3556 is isolated whereas NGC 4631 is interacting. Thus NGC 3556 presents a more pristine environment for studying the disk-halo interaction.
