description: Misalignments between the rotation axis of stars and gas are an indication of external processes shaping galaxies throughout their evolution. Using observations of 3068 galaxies from the SAMI Galaxy Survey, we compute global kinematic position angles for 1445 objects with reliable kinematics and identify 169 (12%) galaxies which show stellar-gas misalignments. Kinematically decoupled features are more prevalent in early-type/passive galaxies compared to late-type/star-forming systems. Star formation is the main source of gas ionisation in only 22% of misaligned galaxies; 17% are Seyfert objects, while 61% show Low-Ionisation Nuclear Emission-line Region features. We identify the most probable physical cause of the kinematic decoupling and find that, while accretion-driven cases are dominant, for up to 8% of our sample, the misalignment may be tracing outflowing gas. When considering only misalignments driven by accretion, the acquired gas is feeding active star formation in only $\sim$1/4 of cases. As a population, misaligned galaxies have higher Sérsic indices and lower stellar spin & specific star formation rates than appropriately matched samples of aligned systems. These results suggest that both morphology and star formation/gas content are significantly correlated with the prevalence and timescales of misalignments. Specifically, torques on misaligned gas discs are smaller for more centrally concentrated galaxies, while the newly accreted gas feels lower viscous drag forces in more gas-poor objects. Marginal evidence of star formation not being correlated with misalignment likelihood for late-type galaxies suggests that such morphologies in the nearby Universe might be the result of preferentially aligned accretion at higher redshifts.

Although the Schnirelman Theorem holds, the quantum average of the position $x$ is finite on any eigenstate, while classical ergodicity entails that the classical time average of $x$ is unbounded.

Neutron scattering investigations of the boson peak

Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: Inelastic neutron scattering is not only capable of determining a generalized vibrational density of states around the boson peak of a glass, but can also be used to get information on the eigenvectors. The eigenvectors determine the dynamic structure factor, which is $Q^2S(Q)$ ($Q$ wavevector) for long wavelength sound waves. This enables the determination of the sound wave fraction below and at the boson peak, done for SiO$_2$, B$_2$O$_3$, polybutadiene and amorphous germanium. The temperature dependence of the boson peak in silica and glycerol is shown. X-ray Brillouin scattering data show that the damping of the longitudinal sound waves in silica and glycerol follows the soft potential model $ω^4$ prediction in the limit of low frequency.

description: This study aims to analyze and quantify the short- and long-run impact of agricultural exports–both traditional and nontraditional products–on economic growth of Peru using an annual time series data from 2000 to 2016 obtained from the Central Bank of Peru and the World Bank. Traditional agricultural exports value, non-traditional agricultural exports value, labor force and fixed capital formation value for each year of the stipulated period were used as determinant factors of the economic growth. A Vector Autoregression (VAR) Model, Augmented Dickey-Fuller (ADF) test, Johansen Co-integration test and Granger Causality test were employed for data analysis. The findings revealed that in the short run, traditional agricultural exports have had a positive but non-significant effect on economic growth while non-traditional agricultural exports have had a positive and significant effect on Gross Domestic Product (GDP). Meanwhile, both fixed capital formation and the labor force have had a significant effect on the GDP, albeit in different directions. The ADF test showed that, with the exception of traditional agricultural exports and fixed capital formation, all determinants became stationary at a level I (0). Moreover, the Co-integration result showed that there is a long-run relationship between the studied variables and a unidirectional causality in the relation between the determinant variables and economic growth.

description: Quantum communications promise to revolutionise the way information is exchanged and protected. Unlike their classical counterpart, they are based on dim optical pulses that cannot be amplified by conventional optical repeaters. Consequently they are heavily impaired by propagation channel losses, which confine their transmission rate and range below a theoretical limit known as repeaterless secret key capacity. Overcoming this limit with today's technology was believed to be impossible until the recent proposal of a scheme that uses phase-coherent optical signals and an auxiliary measuring station to distribute quantum information. Here we experimentally demonstrate such a scheme for the first time and over significant channel losses, in excess of 90 dB. In the high loss regime, the resulting secure key rate exceeds the repeaterless secret key capacity, a result never achieved before. This represents a major step in promoting quantum communications as a dependable resource in today's world.

description: We report the Fermi Large Area Telescope (Fermi-LAT) detection of the $γ$-ray emission toward the massive star forming region of Carina Nebula Complex (CNC). Using the latest source catalog and diffuse background models, we found that the GeV $γ$-ray emission in this region can be resolved into three different components. The GeV $γ$-ray emission from the central point source is considered to originate from the Eta Carina ($η$ Car). We further found the diffuse GeV $γ$-ray emission around the CNC which can be modelled by two Gaussian disks with radii of 0.4°(region A) and 0.75°(region B), respectively. The GeV $γ$-ray emission from both the regions A and B have good spatial consistency with the derived molecular gas in projection on the sky. The GeV $γ$-ray emission of region A reveals a characteristic spectral shape of the pion-decay process, which indicates that the $γ$-rays are produced by the interactions of hadronic cosmic rays with ambient gas. The $γ$-rays spectrum of region B has a hard photon index of 2.12 $\pm$ 0.02, which is similar to other young massive star clusters. We argue that the diffuse GeV $γ$-ray emission in region A and region B likely originate from the interaction of accelerated protons in clusters with the ambient gas.

description: Quality and safety are important attributes for consumers in developed and transitional countries such as Kosovo. This study aims to examine Kosovar consumers’ characteristics, attitude and preferences towards meat as well as to provide meat consumer profiling using a descriptive analysis together with the Food-Related Lifestyle approach. We drew a sample of 300 Kosovar consumers by means of intercept sampling in Prishtina, Prizren and Gjilan. Results suggest that Kosovar consumers perceive country of origin (COO), especially domestic origin, as an indicator of quality and safety for meat. Two consumer profiles were identified through segmentation analysis: conservative and innovative food consumers. The innovative food consumer is the most interesting target segment for Kosovar meat. There is potentially a market for meat products bearing food safety and origin labels. Therefore, private operators could consider the use of safety certification labels to signal to consumers that their products are safer than common products. The paper concludes by discussing the implications of our findings for businesses and policy makers regarding domestic meat promotion strategies.

In this paper, we show in a geometric way that every building of type E6 contains, up to conjugacy, a unique class of symplectic polarities. We also show that the natural point-line geometry of each split building of type F4 fully embedded in the natural point-line geometry of Δ arises from a symplectic polarity.

description: We propose a scalable quantum-computing architecture based on cold atoms confined to sites of a tight optical lattice. The lattice is placed in a non-uniform magnetic field and the resulting Zeeman sublevels define qubit states. Microwave pulses tuned to space-dependent resonant frequencies are used for individual addressing. The atoms interact via magnetic-dipole interactions allowing implementation of a universal controlled-NOT gate. The resulting gate operation times for alkalis are on the order of milliseconds, much faster then the anticipated decoherence times. Single qubit operations take about 10 microseconds. Analysis of motional decoherence due to NOT operations is given. We also comment on the improved feasibility of the proposed architecture with complex open-shell atoms, such as Cr, Eu and metastable alkaline-earth atoms with larger magnetic moments.

description: Although a large number of Galactic open clusters (OCs) have been identified, the internal kinematic properties (e.g., rotation) of almost all the known OCs are still far from clear. With the high-precision astrometric data of Gaia EDR3, we have developed a methodology to unveil the rotational properties of the Praesepe cluster. Statistics of the three-dimensional residual motions of the member stars reveal the presence of Praesepe's rotation and determine its spatial rotation axis. The mean rotation velocity of the Praesepe cluster within its tidal radius is estimated to be 0.2 $\pm$ 0.05 km s$^{-1}$, and the corresponding rotation axis is tilted in relation to the Galactic plane with an angle of 41 $\pm$ 12 degree. We also analysed the rms rotational velocity of the member stars around the rotation axis, and found that the rotation of the member stars within the tidal radius of Praesepe probably follows the Newton's classical theorems.

description: Highly oriented pyrolitic graphite (HOPG) is an inert substrate with a structural honeycomb lattice, well suited for the growth of two-dimensional (2D) silicene layer. It was reported that when Si atoms are deposited on HOPG surface at room temperature, they arrange in two configurations: silicene nanosheets and three dimensional clusters. In this work we demonstrate, by using scanning tunneling microscopy (STM) and Raman spectroscopy, that a third configuration stabilizes in the form of Si 2D nanosheets intercalated below the first top layer of carbon atoms. The Raman spectra reveal a structure located at 538 cm$^{-1}$ which we ascribe to the presence of sp$^2$ Si hybridization. Moreover, the silicon deposition induces several modifications in the graphite D and G Raman modes, which we interpret as an experimental evidence of the intercalation of the silicene nanosheets. The Si atom intercalation at room temperature takes place at the HOPG step edges and it detaches only the outermost graphene layer inducing a strong tensile strain mainly concentrated on the edges of the silicene nanosheets. Theoretical calculations of the structure and energetic viability of the silicene nanosheets, of the strain distribution on the outermost graphene layer and its influence on the Raman resonances support the STM and Raman observations.

Sie thematisiert die Bedeutung einer religionssensiblen Sozialen Arbeit, die darauf abzielt, die religiösen und kulturellen Hintergründe der Klient*innen zu respektieren und in die pädagogische Praxis zu integrieren. Anhand von Expert*inneninterviews wird untersucht, wie gut die Konzepte der Religionssensibilität in der Praxis umgesetzt werden und welche Kompetenzen Fachkräfte benötigen, um effektiv mit religiösen Themen und Praktiken umzugehen. Die Analyse zeigt, dass viele Fachkräfte täglich mit den religiösen Bedürfnissen ihrer Klient*innen konfrontiert sind, jedoch häufig nicht über das notwendige Wissen oder die Reflexionsfähigkeiten verfügen. Die Ergebnisse der Untersuchung verdeutlichen die Dringlichkeit einer fundierten Ausbildung in theologischen und religionswissenschaftlichen Inhalten sowie die Notwendigkeit regelmäßiger Fortbildungen. Zudem werden Impulse für eine verbesserte Teamarbeit und interdisziplinäre Kooperationen gegeben, um die Herausforderungen in der praktischen Arbeit zu meistern. Diese Arbeit liefert somit nicht nur eine fundierte Analyse der aktuellen Situation, sondern auch konkrete Empfehlungen zur Optimierung der Sozialen Arbeit mit umF, die für den Fachbereich von großer Relevanz sind.

description: Basic models which give rise to one- and two-dimensional (1D and 2D) solitons, such as the Gross-Pitaevskii (GP) equations for Bose-Einstein condensates (BECs), feature the Galilean invariance, which makes it possible to generate families of moving solitons from quiescent ones. A challenging problem is to find models admitting stable self-accelerating (SA) motion of solitons. SA modes are known in linear systems in the form of Airy waves, but they are poorly localized states. This brief review presents two-component BEC models which make it possible to predict SA solitons. In one system, a pair of interacting 1D solitons with opposite signs of the effective mass is created in a binary BEC trapped in an optical-lattice potential. In that case, opposite interaction forces, acting on the solitons with positive and negative masses, produce equal accelerations, while the total momentum is conserved. The second model is based on a system of GP equations for two atomic components, which are resonantly coupled by a microwave field. The latter model produces an exact transformation to an accelerating references frame, thus predicting 1D and 2D stable SA solitons, including vortex rings.

The rotational broadening and the mass of the donor star of GRS 1915+105

Publisher: name: arXiv

description: The binary parameters of the microquasar GRS 1915+105 have been determined by the detection of Doppler-shifted 12CO and 13CO lines in its K-band spectrum (Greiner et al., 2001, Nature, 414, 522). Here, we present further analysis of the same K-band VLT spectra and we derive a rotational broadening of the donor star of V sin i=26+-3 km/s from the 12CO/13CO lines. Assuming that the K-type star is tidally locked to the black hole and is filling its Roche-lobe surface, then the implied mass ratio is q = M_d/M_x = 0.058+-0.033. This result, combined with (P, K, i)=(33.5 d, 140 km/s, 66 deg) gives a more refined mass estimate for the black hole, $M_x=14.0+-4.4 M_{\odot}$, than previously estimated, using an inclination of i=66+-2 deg (Fender et al. 1999) as derived from the orientation of the radio jets and a more accurate distance. The mass for the early K-type giant star is $M_d=0.81\pm0.53 M_{\odot}$, consistent with a more evolved stripped-giant donor star in GRS 1915+105 than, for example, the donor star of the prototype black-hole X-ray transient, V404 Cyg which has the longest binary period after GRS 1915+105.

description: We investigate the quantum numbers of the pentaquark states $\textrm{P}_{\textrm{c}}^{+}$, which are composed of four (three flavors) quarks and an antiquark, by analyzing their inherent nodal structure in this paper. Assuming that the four quarks form a tetrahedron or a square, and the antiquark locates at the center of the four quark cluster, we determine the nodeless structure of the states with orbital angular moment $L \leq 3$, and in turn, the accessible low-lying states. Since the inherent nodal structure depends only on the inherent geometric symmetry, we propose the quantum numbers $J^{P}$ of the low-lying pentaquark states $\textrm{P}_{c}^{+}$ may be ${\frac{3}{2}}^{-}$, ${\frac{5}{2}}^{-} $, ${\frac{3}{2}}^{+}$, ${\frac{5}{2}}^{+} $, independent of dynamical models.

description: Organic farming is considered to be a sustainable land use system and is therefore specifically supported. Although the interactions between organic farming and the resulting socially relevant environmental benefits have received widespread recognition in science and politics, the potential of organic farming to solve the environmental and resource challenges of our time are still assessed differently. Against this background, the aim of this study was to conduct a comprehensive analysis and evaluation of scientific studies on public goods provided by organic farming in the following areas: water protection, soil fertility, biodiversity, climate protection, climate adaptation, resource efficiency, and animal welfare. As part of a literature review, a total of 528 studies with 2,816 pairs (organic vs. conventional farming) were selected for the analysis. These studies had to meet the following criteria: (a) publication period: January 1990 to March 2018; (b) region: temperate climates; (c) study design: at least one organic / conventional pair, and (d) language: studies in German or English. The results of the comparisons between organic and conventional farming were statistically evaluated (min values, max values, mean values, median) and graphically illustrated using box plot diagrams. In addition, the results of the organic variant of the individual pairs were classified on the basis of quantitative criteria with regard to their relative characteristics compared to the conventional variant (Organic +, Organic =, Organic ‐). Across all indicators for the fields of environmental protection and resource conservation, organic management showed advantages over conventional management in 58 % of the pairs analysed. No differences were found for 28 %, and in 14 % of the comparison pairs, the conventional management was more advantageous. No clear picture was drawn regarding animal welfare. No substantial differences were found between organic and conventional livestock across all animal species and production forms in 46 % of the comparison pairs. The organic management showed advantages in 35 % of the pairs, whereas the conventional version performed better in 19 % of the pairs. However, very few studies have been found considering animal welfare in a comprehensive sense...

description: We present the first in a series of microscopic studies of electrical transport through individual molecules with metallic contacts. We view the molecules as ``heterostructures'' composed of chemically well-defined atomic groups, and analyze the device characteristics in terms of the charge and potential response of these atomic-groups to the perturbation induced by the metal-molecule coupling and the applied electrical field, which are modeled using a first-principles based self-consistent matrix Green's function (SCMGF) method. As the first example, we examine the devices formed by attaching two benzene-based molecular radicals--phenyl dithiol (PDT) and biphenyl dithiol (BPD)--symmetrically onto two semi-infinite gold electrodes through the end sulfur atoms.

description: Understanding the physical formation of the Hubble sequence remains one of the most important unsolved astrophysical problems. Searches for proto-disks and proto-ellipticals can now be effectively done using deep wide-field Hubble Space Telescope images taken with the new Advanced Camera for Surveys. Through an analysis of concentrations (C), asymmetries (A) and clumpiness values (S) (CAS) of galaxies found in the GOODS Field South, we are able to identify objects possibly forming onto the Hubble sequence. Using this approach, we detect a sizeable population of star forming luminous diffuse objects and star forming luminous asymmetric objects between redshifts 0.5 < z < 2. These galaxies have extremely low light concentrations, or high asymmetries, with absolute magnitudes M_B < -19. The luminous diffuse objects are found in abundance between z = 1 - 2, with fewer objects at z > 2 and z < 1. The luminous asymmetric objects are found at a similar abundance, with a peak at z~1. We argue that these galaxies are a subset of modern disks and ellipticals in formation. The co-moving volume density of the luminous diffuse objects between z = 1 - 2 is similar to the local density of bright disk galaxies, with values ~5*10^{5} Gpc^{-3}. The SEDs of these objects are mostly consistent with starbursts, or star-forming normal galaxies, with average uncorrected for extinction star formation rates of ~4 M_0 yr^{-1}. These galaxies also host 35-40% of the star formation activity at 1 < z < 2. We briefly discuss the implications of these objects for understanding the origin of the Hubble sequence.

description: Phosphorus is an essential plant nutrient required by all living organisms and global phosphate resources, being finite, are expected to last another 125 years. This study investigated a sustainable approach to retrieving phosphates from aqueous media using a composite of commonly available biological and mineral sources. Two composites were synthesized using (i) feldspar, alginate, and agar cross-linked by ferric and calcium ions (FAA), and (ii) feldspar, fly ash, and alginate crosslinked with copper ions (FFA). Adsorption parameters were determined using a synthetic phosphate solution. The FAA composite adsorbed 69% of the phosphates within 4 hours; 81% was adsorbed after equilibrium was reached in 9.5 h (pH 4–10). The FFA composite adsorbed 82% of the phosphate reaching equilibrium after 5.5 h (pH 3–7). Characterization of the composite by scanning electron microscopy and Fourier Transform Infrared spectroscopy showed the presence of inorganic and organic functional groups in the agar and alginate that could adsorb phosphate ions. The kinetic and isotherm data suggest that the phosphate ions migrate to the composite boundary and are precipitated by the Ca2+, Fe3+, and Cu2+ in the composite matrix. Once the outer composite is saturated, the rest of the phosphate ions are entrapped by the biopolymers through H and covalent bonding. These two biopolymer composites can be easily synthesized and scaled up for phosphate adsorption. Recovery of the adsorbed phosphates, in future studies, can be used for plant nutrition to complete the open-ended cycle of phosphates leaching into water bodies.

description: As important parts of the Belt and Road Initiative, West Asia and North Africa have rich resources and prominent strategic position. Anti-poverty has always been a crucial social issue of China, West Asia and North Africa. Through literature review and data analysis, this paper analyzed the current situations of anti-poverty in West Asia and North Africa and the causes of poverty, and objectively summarized the realistic foundation of anti-poverty cooperation between China and West Asian and North African countries. On the basis of current situations, it put forward a path for anti-poverty cooperation between China and West Asian and North African countries, in the hope of providing decision-making basis and policy recommendations for China to undertake anti-poverty cooperation in the worldwide range.

description: The correlations between T, E modes and B modes in cosmic microwave background (CMB) radiation, which are expected to vanish under parity symmetry, have become a sensitive probe of the new physics beyond the standard model. In this paper, we forecast the estimation of TB and EB cross power spectra using NILC and cILC on AliCPT-1 simulations together with Planck HFI and WMAP K maps as ancillary data. We find that, NILC performs better than cILC on measuring TB and EB correlations in light of its lower uncertainties. In terms of the birefringence angle estimation without assuming systematic errors, the combination of CMB TB and EB spectra from NILC cleaned simulations could reach a sensitivity of $|β|<0.058^\circ$ with 2$σ$ significance for the first observing season of AliCPT. Tripling the survey duration will improve this sensitivity to $|β|<0.041^\circ$.

Microscopic study of electrical transport through individual molecules with metallic contacts: II. Effect of the interface structure

description: We investigate the effect on molecular transport due to the different structural aspects of metal-molecule interfaces. The example system chosen is the prototypical molecular device formed by sandwiching the phenyl dithiolate molecule (PDT) between two gold electrodes with different metal-molecule distance, atomic structure at the metallic surface, molecular adsorption geometry and with an additional hydrogen end atom. We find the dependence of the conductance on the metal-molecule interface structure is determined by the competition between the modified metal-molecule coupling and the corresponding modified energy level lineup at the molecular junction. The results of the detailed microscopic calculation can all be understood qualitatively from the equilibrium energy level lineup and the knowledge of the voltage drop across the molecular junction at finite bias voltages.

description: We study to which extent the family of pairs of subspaces of a vector space related to each other via intersection properties determines the vector space. In another language, we study to which extent the family of vertices of the building of a projective space related to each other via several natural respective conditions involving the Weyl distance and incidence determines the building. These results can be seen as generalizations of and variations on the Fundamental Theorem of Projective Geometry.

Ground Penetrating Radar Theory, Data Collection, Processing, and Interpretation: A Guide for Archaeologists
Creators: name: Dojack, Lisa
Publisher: name: The University of British Columbia
Year: 2012

description: This guide was originally written as a term project for a Graduate Research Seminar (Anthropology 545) directed by Dr. Andrew Martindale at the University of British Columbia in 2010-11. It was produced as a teaching tool for students in the Department of Anthropology and other users of the Laboratory of Archaeology’s ground penetrating radar (GPR) equipment. The guide provides a review of GPR theory, data collection, processing, and interpretation, presented in three sections. Section 1 (GPR Fundamentals) focuses on the principles of GPR: how electromagnetic radar waves move through the ground, what happens when they encounter subsurface features, and how they are imaged in GPR software programs. Section 2 (Data Editing and Processing) focuses specifically on what happens to the data after collection in the field, when they are returned to the lab and undergo a variety of processes to transform them into two- and three-dimensional images of the subsurface. Section 3 (Data Interpretation) focuses on how we read these computer-generated images, and provides descriptions of the various signal types that can be produced from common archaeological features. A companion guide focusing on GPR data collection is forthcoming by Steve Daniel.
