description: We present new multi-wavelength scaling relations between the neutral hydrogen content (HI) and the stellar properties of nearby galaxies selected from the HI Parkes All-Sky Survey (HIPASS). We use these new scaling relations to investigate the environmental dependency of the HI content of galaxies. We find that galaxies in high density environments tend to have on average less HI than galaxies with the same stellar mass in the low density environment. Our new HI scaling relations allow us to identify individual galaxies, as well as group/cluster environments, that have an `anomalous' HI content. We map the global distribution of HI-deficient and HI-excess galaxies on the sky and compare it to the large scale structure of galaxies. We find galaxy clusters to be HI-deficient, and we identify that the regions surrounding clusters tend to be HI-excess. Finally, we demonstrate the potential of using HI scaling relations to predict future HI surveys based on an optical redshift survey. We apply our scaling relations to 16709 galaxies in the 6dF Galaxy Survey (6dFGS) that lie in the HIPASS volume and compare our predictions to the measurements. We find that scaling relations are good method to estimate the outcome of HI surveys.

description: 2016 - 2017
description: In this work, several experiments and analyses performed by means of noise spectroscopy, on a broad typology of materials and compounds, are presented. Structural, DC electrical transport and noise properties are exposed for each investigated sample, and theoretical models and possible explanations of the experimental results are given to unravel physical phenomena. In particular, two distinct types of iron-chalcogenide superconductors are investigated, in their pristine and aged state, suggesting the more likely mechanism which generates the resistance fluctuations and resorting to Weak Localization theory. In the case of the polymer/carbon nanotubes composites, the fluctuation-induced tunneling model is introduced to explain the measured temperature dependence of the electrical conductance and the I-V curve behaviors. Then, noise measurements prove the existence of a structural phase transition occurring around 160 K within the perovskite compound and highlight the correlation between electronic defect states distribution and device performance. The variety of investigated devices and materials validates the soundness of the noise spectroscopy as an effective tool for electric transport analysis. [edited by Author]
What if planet 9 has satellites?
Creators: name: Chan, Man Ho
Publisher: name: arXiv
Year: 2023
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: In the past decade, numerical simulations started to reveal the possible existence of planet 9 in our solar system. The planet 9 scenario can provide an excellent explanation to the clustering in orbital elements for Kuiper Belt objects. However, no optical counterpart has been observed so far to verify the planet 9 scenario. Therefore, some recent studies suggest that planet 9 could be a dark object, such as a primordial black hole. In this article, we show that the probability of capturing large trans-Neptunian objects (TNOs) by planet 9 to form a satellite system in the scattered disk region (between the inner Oort cloud and Kuiper Belt) is large. By adopting a benchmark model of planet 9, we show that the tidal effect can heat up the satellites significantly, which can give sufficient thermal radio flux for observations, even if planet 9 is a dark object. This provides a new indirect way for examining the planet 9 hypothesis and revealing the basic properties of planet 9.

description: The layered square-planar nickelates, Nd$_{n+1}$Ni$_{n}$O$_{2n+2}$, are an appealing system to tune the electronic properties of square-planar nickelates via dimensionality; indeed, superconductivity was recently observed in Nd$_{6}$Ni$_{5}$O$_{12}$ thin films. Here, we investigate the role of epitaxial strain in the competing requirements for the synthesis of the $n=3$ Ruddlesden-Popper compound, Nd$_{4}$Ni$_{3}$O$_{10}$, and subsequent reduction to the square-planar phase, Nd$_{4}$Ni$_{3}$O$_{8}$. We synthesize our highest quality Nd$_{4}$Ni$_{3}$O$_{10}$ films under compressive strain on LaAlO$_{3}$ (001), while Nd$_{4}$Ni$_{3}$O$_{10}$ on NdGaO$_{3}$ (110) exhibits tensile strain-induced rock salt faults but retains bulk-like transport properties. A high density of extended defects forms in Nd$_{4}$Ni$_{3}$O$_{10}$ on SrTiO$_{3}$ (001). Films reduced on LaAlO$_{3}$ become insulating and form compressive strain-induced $c$-axis canting defects, while Nd$_{4}$Ni$_{3}$O$_{8}$ films on NdGaO$_{3}$ are metallic. This work provides a pathway to the synthesis of Nd$_{n+1}$Ni$_{n}$O$_{2n+2}$ thin films and sets limits on the ability to strain engineer these compounds via epitaxy.

As for type genus.
Remarks
The semiprosoporous male ducts (one pair prosoporous, one plesioporous) somewhat resemble the basic arrangement of the Lumbriculidae —typical members of which have a similar body form, including four pairs of chaetae per segment. However, morphology of the reproductive system appears closer to another monotypic family, Kurenkovidae Sokolskaja, 1983 —although the single species, Kurenkovia magna Sokolskaja, 1969 has subsequently been placed within in the Lumbriculidae, based on the (morphological) cladistic analysis of Brinkhurst (1989). The family Limpluvidae is currently monotypic, and morphologically distinguished by the characters listed below in the genus diagnosis and species description for Limpluvia setoensis.

description: Many massive stars travel through the interstellar medium at supersonic speeds. As a result they form bow shocks at the interface between the stellar wind. We use numerical hydrodynamics to reproduce such bow shocks numerically, creating models that can be compared to observations. In this paper we discuss the influence of two physical phenomena, interstellar magnetic fields and the presence of interstellar dust grains on the observable shape of the bow shocks of massive stars. We find that the interstellar magnetic field, though too weak to restrict the general shape of the bow shock, reduces the size of the instabilities that would otherwise be observed in the bow shock of a red supergiant. The interstellar dust grains, due to their inertia can penetrate deep into the bow shock structure of a main sequence O-supergiant, crossing over from the ISM into the stellar wind. Therefore, the dust distribution may not always reflect the morphology of the gas. This is an important consideration for infrared observations, which are dominated by dust emission. Our models clearly show, that the bow shocks of massive stars are useful diagnostic tools that can used to investigate the properties of both the stellar wind as well as the interstellar medium.

In many cases their detection hinges on their infrequent interactions with Standard Model photons at sub-eV energies. We describe the design and performance of an experiment to search for aberrations from the broadband noise power associated with a 5 K copper resonant cavity in the vicinity of 34 GHz (0.1 meV). The cavity, microwave receiver, and data reduction are described. Several configurations of the experiment are discussed in terms of their impact on the sensitivity of the search for axion-like particles and hidden sector photons.

For astrophysics, the implications of such a discovery will rely on the reconstruction of the neutrino arrival direction. This paper describes a first complete neutrino arrival direction reconstruction for detectors employing deep antennas such as RNO-G or planning to employ them like IceCube-Gen2. We will didactically introduce the challenges of neutrino direction reconstruction using radio emission in ice, elaborate on the detail of the algorithm used, and describe the obtainable performance based on a simulation study and discuss its implication for astrophysics.

description: In this work, the microstructure of concrete elements printed in an industrial printing facility is assessed using Scanning Electron Microscopy (SEM), Mercury Intrusion Porosimetry (MIP) and X-ray micro-tomography. All printing parameters and curing conditions are chosen to create extreme and detrimental printing conditions in an industrial production factory. The studied elements are printed in various exposure conditions in terms of external desiccation. In our measurements, we make a distinction between the microstructural modifications of the interface between layers, which may be at the origin of preferred propagation paths for ionic species in the liquid phase, and the microstructural modifications of the bulk material linked to the absence of a protective mold. Our results suggest that material drying on time scales between tens of minutes and couple hours drives the changes in the material microstructure, porosity and pore size distribution. Many features are similar to the ones typically observed for the well-known self-desiccation of hydrating cement-based materials. The ones observed here are however fully driven by the water exchange with the environment and happen before hydration starts to leave the induction period.

The fluorination treatment acts as a local chemical switch that alters the charge state of nitrogen-vacancy luminescence centers from the neutral to the negative state. The electron beam fluorination process is highly localized and can be used to control the emission spectrum of individual nanodiamonds and surface regions scanned by the electron beam

description: This article aims to investigate volatile constituents and antiacetylcholinesterase, antileishmanial and antiproliferative activities of hexane extracts from Capsicum chinense fruit (unripe bode pepper ‘HE-UB’ and ripe little beak pepper ‘HE-RB’). HE-UB and HE-RB were screened by the microplate assay method to determine their antiacetylcholinesterase activity. Both exhibited inhibitory potential, i. e., IC50 = 41.5 and 20.3 µg/mL, respectively. HE-UB (IC50 = 67.19 µg/mL) and HE-RB (IC50 = 38.16 µg/mL) exhibited antileishmanial activity against promastigote forms of Leishmania (Leishmania) amazonensis. In addition, HE-UB and HE-RB demonstrated cytotoxic activity against different human tumor cell lines with IC50 ranging from 325.40 to 425.0 µg/mL. Both GC-FID and GC-MS analyses revealed that the major component in both extracts was E-caryophyllene. In short, HE-RB was more satisfactory than HE-UB in all in vitro activities under evaluation. These findings may be used as initial data for further studies of Capsicum species.

We furthermore establish the relation of the Chebyshev iteration to real-time evolution, and discuss technical aspects as computation time and implementation in detail.

description: As one of the most luminous Cepheids in the Milky Way, the 41.5-day RS Puppis is an analog of the long-period Cepheids used to measure extragalactic distances. An accurate distance to this star would therefore help anchor the zero-point of the bright end of the period-luminosity relation. But, at a distance of about 2 kpc, RS Pup is too far away for measuring a direct trigonometric parallax with a precision of a few percent with existing instrumentation. RS Pup is unique in being surrounded by a reflection nebula, whose brightness varies as pulses of light from the Cepheid propagate outwards. We present new polarimetric imaging of the nebula obtained with HST/ACS. The derived map of the degree of linear polarization pL allows us to reconstruct the three-dimensional structure of the dust distribution. To retrieve the scattering angle from the pL value, we consider two different polarization models, one based on a Milky Way dust mixture and one assuming Rayleigh scattering. Considering the derived dust distribution in the nebula, we adjust a model of the phase lag of the photometric variations over selected nebular features to retrieve the distance of RS Pup. We obtain a distance of 1910 +/- 80 pc (4.2%), corresponding to a parallax of 0.524 +/- 0.022 mas. The agreement between the two polarization models we considered is good, but the final uncertainty is dominated by systematics in the adopted model parameters. The distance we obtain is consistent with existing measurements from the literature, but light echoes provide a distance estimate that is not subject to the same systematic uncertainties as other estimators (e.g. the Baade-Wesselink technique). RS Pup therefore provides an important fiducial for the calibration of systematic uncertainties of the long-period Cepheid distance scale.

description: Maximum bipartite matching is a fundamental algorithmic problem which can be solved in polynomial time. We consider a natural variant in which there is a separation constraint: the vertices on one side lie on a path or a grid, and two vertices that are close to each other are not allowed to be matched simultaneously. We show that the problem is hard to approximate even for paths, and provide constant-factor approximation algorithms for both paths and grids.

description: Driven by recent RHESSI observations of confined loop-top hard X-ray sources in solar flares, we consider stochastic acceleration of electrons in the presence of Coulomb collisions. If electron escape from the acceleration region can be neglected, the electron distribution function is determined by a balance between diffusive acceleration and collisions. Such a scenario admits a stationary solution for the electron distribution function that takes the form of a kappa distribution. We show that the evolution toward this kappa distribution involves a "wave front" propagating forwards in velocity space, so that electrons of higher energy are accelerated later; the acceleration time scales with energy according to $τ_{\rm acc} \sim E^{3/2}$. At sufficiently high energies escape from the finite-length acceleration region will eventually dominate. For such energies, the electron velocity distribution function is obtained by solving a time-dependent Fokker-Planck equation in the "leaky-box" approximation. Solutions are obtained in the limit of a small escape rate from an acceleration region that can effectively be considered a thick target.

description: Chemical investigation of ethyl acetate extract from the aerial parts of Helleborus cyclophyllus (A.Braun) Boiss. led to the isolation of ten natural products, and their structures were identified to be: 2-deoxy-D-ribono-1,4-lactone (1), 2-O-feruloyl-L-malate (2), three flavonoids: quercetin 3-O-β-D-galactopyranoside (3), quercetin 3-O-6′′-(3-hydroxy-3-methyl-gloutaryl)-β-D-glucopyranoside (4) and quercetin 3-O-(2‴-caffeoylsophoroside) (5), 6-O-caffeoyl-1-O-p-coumaroyl-β-D-glucopyranoside (6), two ecdysteroids: 20-hydroxyecdysone (7) and polypodine B (8) and two bufadienolides: deglucohellebrin (9) and hellebrin (10), on the basis of MS and NMR spectra. This is the first report on the occurrence of compounds (2)-(6) in the genus Helleborus. The chemotaxonomic significance of these compounds was summarised. Bioactivity score, molecular and pharmacokinetic properties of the isolated compounds were calculated by online computer software program Molinspiration. Compounds showed promising bioactivity scores for drug targets. Moreover, some of the isolated phenolic compounds were tested for their antioxidant and antiinflammatory activities. Tested compounds presented antioxidant ability correlated to the presence of the phenolic hydroxyl groups.

description: Topological superconductivity is an exotic state of matter that supports Majorana zero-modes, which are surface modes in 3D, edge modes in 2D or localized end states in 1D. In the case of complete localization these Majorana modes obey non-Abelian exchange statistics making them interesting building blocks for topological quantum computing. Here we report superconductivity induced into the edge modes of semiconducting InAs/GaSb quantum wells, a two-dimensional topological insulator. Using superconducting quantum interference, we demonstrate gate-tuning between edge-dominated and bulk-dominated regimes of superconducting transport. The edge-dominated regime arises only under conditions of high-bulk resistivity, which we associate with the 2D topological phase. These experiments establish InAs/GaSb as a robust platform for further confinement of Majoranas into localized states enabling future investigations of non-Abelian statistics.

Er verweist auf das gezielte Töten, das Kriegsspiele, insbesondere Ego-Shooterspiele charakterisiert. Am 25. Juni kam nun überraschend ein außergewöhnliches Spiel zum Ersten Weltkrieg, „Valiant Hearts: The Great War“2, auf den Markt, in dem der Spieler andere nicht tötet, sondern diesen hilft. Das Spiel setzt dabei auf positiv konnotierte Gefühle wie Liebe und Freundschaft der am Krieg Beteiligten – und zwar bemerkenswerterweise über nationale Grenzen hinweg.3 Dabei bewegt sich das Geschehen zwischen Fiktion und Fakten.

description: We examined variations in the 160/250 and 250/350 micron surface brightness ratios within 24 nearby (<30 Mpc) face-on spiral galaxies observed with the Herschel Space Observatory to identify the heating mechanisms for dust emitting at these wavelengths. The analysis consisted of both qualitative and quantitative comparisons of the 160/250 and 250/350 micron ratios to H alpha and 24 micron surface brightnesses, which trace the light from star forming regions, and 3.6 micron emission, which traces the light from the older stellar populations of the galaxies. We find broad variations in the heating mechanisms for the dust. In one subset of galaxies, we found evidence that emission at <=160 microns (and in rare cases potentially at <=350 microns) originates from dust heated by star forming regions. In another subset, we found that the emission at >=250 microns (and sometimes at >=160 microns) originates from dust heated by the older stellar population. In the rest of the sample, either the results are indeterminate or both of these stellar populations may contribute equally to the global dust heating. The observed variations in dust heating mechanisms does not necessarily match what has been predicted by dust emission and radiative transfer models, which could lead to overestimated dust temperatures, underestimated dust masses, false detections of variability in dust emissivity, and inaccurate star formation rate measurements.

description: To our knowledge, literature describing the place of care and associated costs during acute bipolar I disorder (BP-I) episodes is limited. We conducted a claims-based retrospective study to address this gap. Adults with BP-I were identified via IBM MarketScan Commercial and Medicare Supplemental databases. The acute episode index date was defined by ≥1 inpatient BP-I claim(s) or ≥1 outpatient or ≥3 outpatient BP-I claims (depending on visit type) in a 2-week (manic/mixed) or 4-week (depressive) period. Likely acute episodes were defined as 3- and 6-week periods for manic/mixed and depressive episodes, respectively; total mental health-related medical costs (health plan + patient) were collected during these intervals and stratified by setting (inpatient versus outpatient). Initial and subsequent episodes were captured; data were reported in subgroups without and with clozapine use, a proxy for disease severity. The remission index date was the earliest outpatient claim with a bipolar remission diagnosis with no acute episode or treatment. Remission costs were collected over a 3-month period. All results were analyzed descriptively. A total of 41,516 patients with 130,221 acute manic/mixed episodes and 47,763 patients with 149,207 acute depressive episodes met the study criteria. Over 84% of acute episodes were treated in outpatient settings. Mental health-related medical costs for manic/mixed episodes were $15,444 for inpatient and $1,577 for outpatient settings; inpatient and outpatient costs for depressive episodes were $17,376 and $2,154, respectively. Health plans covered approximately 78% of medical costs for both episode types with and without prior clozapine use. A total of 8,143 patients met remission criteria; the total 3-month outpatient costs were $1,225. Most BP-I acute manic/mixed or depressive episodes were treated in the outpatient setting. Episodes with inpatient care were 8–10 times more costly than outpatient-only episodes. Health plans covered most medical costs, but additional patient-incurred out-of-pocket costs remained.

description: Frequency-bin qubits possess unique synergies with wavelength-multiplexed lightwave communications, suggesting valuable opportunities for quantum networking with the existing fiber-optic infrastructure. Although the coherent manipulation of frequency-bin states requires highly controllable multi-spectral-mode interference, the quantum frequency processor (QFP) provides a scalable path for gate synthesis leveraging standard telecom components. Here we summarize the state of the art in experimental QFP characterization. Distinguishing between physically motivated ''open box'' approaches that treat the QFP as a multiport interferometer, and ''black box'' approaches that view the QFP as a general quantum operation, we highlight the assumptions and results of multiple techniques, including quantum process tomography of a tunable beamsplitter -- to our knowledge the first full process tomography of any frequency-bin operation. Our findings should inform future characterization efforts as the QFP increasingly moves beyond proof-of-principle tabletop demonstrations toward integrated devices and deployed quantum networking experiments.
