description: We have obtained near-infrared spectra covering the Ca II triplet lines for a number of stars associated with 16 SMC clusters using the VLT + FORS2. These data compose the largest available sample of SMC clusters with spectroscopically derived abundances and velocities. Our clusters span a wide range of ages and provide good areal coverage of the galaxy. Cluster members are selected using a combination of their positions relative to the cluster center as well as their abundances and radial velocities. We determine mean cluster velocities to typically 2.7 km/s and metallicities to 0.05 dex (random errors), from an average of 6.4 members per cluster. (continued in paper)

description: Using a sample of 57,377 star-forming galaxies drawn from the Sloan Digital Sky Survey, we study the relationship between gas-phase oxygen abundance and environment in the local Universe. We find that there is a strong relationship between metallicity and environment such that more metal-rich galaxies favor regions of higher overdensity. Furthermore, this metallicity-density relation is comparable in strength to the color-density relation along the blue cloud. After removing the mean dependence of environment on color and luminosity, we find a significant residual trend between metallicity and environment that is largely driven by galaxies in high-density regions, such as groups and clusters. We discuss the potential source of this relationship between metallicity and local galaxy density in the context of feedback models, with special attention paid to quantifying the impact of environment on the scatter in the mass-metallicity relation. We find that environment is a non-negligible source of scatter in this fundamental relation, with > 15% of the measured scatter correlated with environment.

description: Duchenne Muscular Dystrophy (DMD) is an X-linked recessive congenital myopathy, with a low prevalence but a high mortality rate. It is due to different mutations of the DMD gene, the largest gene of the human genome, and leads to the production of a non-functional dystrophin, a fundamental protein responsible for muscle integrity. DMD is transmitted by female carriers and is characterized by a generalized progressive muscular dystrophy and weakness in males, being fatal before the age of 20 years due to cardiorespiratory failure. The aim of this study was to perform an integrative systematic review about the effect of interventions on DMD mutations of the information available in randomized studies with non-randomized studies. A research protocol was designed following the PICO methodology. Bibliography eligibility criteria were defined to answer the PICO’s question. Three independent searches were performed, namely in Cochrane, PubMed and Google. The data collection methodology used eligibility criteria. To extract information, five variables have been parameterized. Fifty-four papers were included in this integrative systematic review. Because scientists have succeeded in locating DNA errors and mutations with increasingly precise technologies, we are now able to develop new therapies that make it possible to avoid, bypass or edit the mutated DNA. There is information in non-randomized studies on the effect of interventions on DMD mutations. There are few therapies available for DMD mutations. Combining information from non-randomized studies with information available from randomized studies on the effect of interventions on DMD mutations, DNA analyses and advances in biomolecular science are confirmed and represent the basis of therapies with a direct impact on the predictability of disease progression.

description: We analyze the finite size corrections to entanglement in quantum critical systems. By using conformal symmetry and density functional theory, we discuss the structure of the finite size contributions to a general measure of ground state entanglement, which are ruled by the central charge of the underlying conformal field theory. More generally, we show that all conformal towers formed by an infinite number of excited states (as the size of the system $L \to \infty$) exhibit a unique pattern of entanglement, which differ only at leading order $(1/L)^2$. In this case, entanglement is also shown to obey a universal structure, given by the anomalous dimensions of the primary operators of the theory. As an illustration, we discuss the behavior of pairwise entanglement for the eigenspectrum of the spin-1/2 XXZ chain with an arbitrary length $L$ for both periodic and twisted boundary conditions.

A New Channel for Detecting Dark Matter Substructure in Galaxies: Gravitational Lens Time Delays
Creators: name: Keeton, Charles R.

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)

description: We show that dark matter substructure in galaxy-scale halos perturbs the time delays between images in strong gravitational lens systems. The variance of the effect depends on the subhalo mass function, scaling as the product of the substructure mass fraction and a characteristic mass of subhalos (namely /). Time delay perturbations therefore complement gravitational lens flux ratio anomalies and astrometric perturbations by measuring a different moment of the subhalo mass function. Unlike flux ratio anomalies, "time delay millilensing" is unaffected by dust extinction or stellar microlensing in the lens galaxy. Furthermore, we show that time delay ratios are immune to the radial profile degeneracy that usually plagues lens modeling. We lay out a mathematical theory of time delay perturbations and find it to be tractable and attractive. We predict that in "cusp" lenses with close triplets of images, substructure may change the arrival-time order of the images (compared with smooth models). We discuss the possibility that this effect has already been observed in RX J1131-1231.

description: We have investigated cobaltite relatives of the layered perovskite cuprates and nickelates, Pr$_{2-x}$Ca$_x$CoO$_4$ ($0.39 \leq x \leq 0.73$) and La$_{2-x}$Sr$_x$CoO$_4$ ($x = 0.61$), using elastic neutron scattering. We have discovered doping-dependent incommensurate short-range ordering of charges and magnetic moments, which in cobaltites occur in the range of heavy doping, $ 0.5 \lesssim x \lesssim 0.75$. The charge order exists already at room temperature and shows no change on cooling. The incommensurability of its propagation vector, ${\bf Q}_c = (ε_c,0,l)$, roughly scales with the concentration of Co$^{2+}$ ions, $ε_c \sim (1-x)$. Magnetic order is only established at low T$\lesssim 40$ K and has twice larger periodicity, indicating a dominant antiferromagnetic correlation between the nearest Co$^{2+}$ spins.

description: COVID-19 pandemic has brought unprecedented changes to office-based workers. This research investigates how the work-life balance was affected for Australian accountants with pre-school and primary school aged children whose work arrangements were impacted by COVID-19 pandemic lockdown. This research adopts inductive, qualitative research methods and six interviews were conducted with participants with different backgrounds as per Classical Grounded Theory (CGT) methodology to explore the changes in work life and family life of Australian accountants. A conceptual model emerged grounded in the findings from the interviews and triangulated data (as per CGT methodology) which demonstrates that work-life balance is a dynamic process where the physical change of work location forces the movement of boundaries between work and life, thus resulting in the redistribution of discretionary effort to re-balance work and life. This research is important because it explains how change of work arrangements poses an impact on work-life balance of professionals with pre-school and primary school aged children and has potential benefits of enhancing office workers’ wellbeing. Options for future research and limitations are also discussed.
A Halo Model of Galaxy Colors and Clustering in the SDSS

description: Successful halo-model descriptions of the luminosity dependence of clustering distinguish between the central galaxy in a halo and all the others (satellites). To include colors, we provide a prescription for how the color-magnitude relation of centrals and satellites depends on halo mass. This follows from two assumptions: (i) the bimodality of the color distribution at fixed luminosity is independent of halo mass, and (ii) the fraction of satellite galaxies which populate the red sequence increases with luminosity. We show that these two assumptions allow one to build a model of how galaxy clustering depends on color without any additional free parameters than those required to model the luminosity dependence of galaxy clustering. We then show that the resulting model is in good agreement with the distribution and clustering of colors in the SDSS, both by comparing the predicted correlation functions of red and blue galaxies with measurements, and by comparing the predicted color mark correlation function with the measured one. Mark correlation functions are powerful tools for identifying and quantifying correlations between galaxy properties and their environments: our results indicate that the correlation between halo mass and environment is the primary driver for correlations between galaxy colors and the environment; additional correlations associated with halo `assembly bias' are relatively small. Our approach shows explicitly how to construct mock catalogs which include both luminosities {\em and} colors -- thus providing realistic training sets for, e.g., galaxy cluster finding algorithms. Our prescription is the first step towards incorporating the entire spectral energy distribution into the halo model approach.

Parton transport and hadronization from the dynamical quasiparticle point of view

description: The hadronization of an expanding partonic fireball is studied within the Parton-Hadron-Strings Dynamics (PHSD) approach which is based on a dynamical quasiparticle model (DQPM) matched to reproduce lattice QCD results in thermodynamic equilibrium. Apart from strong parton interactions the expansion and development of collective flow is driven by strong gradients in the parton mean-fields. An analysis of the elliptic flow $v_2$ demonstrates a linear correlation with the spatial eccentricity $ε$ as in case of ideal hydrodynamics. The hadronization occurs by quark-antiquark fusion or 3 quark/3 antiquark recombination which is described by covariant transition rates. Since the dynamical quarks become very massive, the formed resonant 'pre-hadronic' color-dipole states ($q\bar{q}$ or $qqq$) are of high invariant mass, too, and sequentially decay to the groundstate meson and baryon octets increasing the total entropy. This solves the entropy problem in hadronization in a natural way. The resulting particle ratios turn out to be in line with those from a grandcanonical partition function at temperature $T \approx 170$ MeV rather independent from the initial temperature and indicate an approximate strangeness equilibration.

description: Elucidating the polymorphism of transition metal dichalcogenide layers and the interplay between structure and properties is a key challenge for the application of these materials. We identify a novel low energy metastable phase of monolayer VSe$_2$ and elucidate its magnetic and electronic properties. This structure is distinct from the previously identified charge density wave (CDW) phase. However, while having rather distinct properties it is very close in energy to the CDW phase and is likely to be realized in experiments. Importantly, local bonding instabilities, as characterized by reconstruction of the electronic structure over a wide energy range, are important for this distortion, which includes both V off-centering in the octahedral coordination cages and a partial disproportionation into two distinct types of V. The phase does not have a ferromagnetic ground state. The results show that the physics of 1$T$ VSe$_2$ are richer than previously known with an interplay of Fermi surface instabilities and local bonding effects.

description: We report our discovery of an extremely rare, low mass, quadruple-lined spectroscopic binary BD-22 5866 (=NLTT 53279, integrated spectral type = M0 V), found during an ongoing search for the youngest M dwarfs in the solar neighborhood. From the cross-correlation function, we are able to measure relative flux levels, estimate the spectral types of the components, and set upper limits on the orbital periods and separations. The resulting system is hierarchical composed of K7 + K7 binary and a M1 + M2 binary with semi-major axes of asini_{A}<=0.06 AU and asini_{B}<=0.30 AU. A subsequent search of the SuperWASP photometric database revealed that the K7 + K7 binary is eclipsing with a period of 2.21 days and at an inclination angle of 85 degrees. Within uncertainties of 5%, the masses and radii of both components appear to be equal (0.59 Msun, 0.61 Rsun). These two tightly orbiting stars (a = 0.035 AU) are in synchronous rotation causing the observed excess Ca II, Halpha, X-ray and UV emission. The fact that the system was unresolved with published adaptive optics imaging, limits the projected physical separation of the two binaries at the time of the observation to d_{AB} < 4.1 AU at the photometric distance of 51 pc. The maximum observed radial velocity difference between the A and B binaries limits the orbit to asini_{AB}<=6.1 AU. As this tight configuration is difficult to reproduce with current formation models of multiple systems, we speculate that an early dynamical process reduced the size of the system such as the interaction of the two binaries with a circumquadruple disk. Intensive photometric, spectroscopic and interferometric monitoring as well as a parallax measurement of this rare quadruple system is certainly warranted.

description: We present majority and minority radiofrequency (RF) spectra of strongly interacting imbalanced Fermi gases of Li-6. We observed a smooth evolution in the nature of pairing correlations from pairing in the superfluid region to polaron binding in the highly polarized normal region. The imbalance induces quasiparticles in the superfluid region even at very low temperature. This leads to a local bimodal spectral response, which allows us to determine the superfluid gap Δand the Hartree energy U.

Path Integral Monte Carlo and Density Functional Molecular Dynamics Simulations of Hot, Dense Helium

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Two first-principles simulation techniques, path integral Monte Carlo (PIMC) and density functional molecular dynamics (DFT-MD), are applied to study hot, dense helium in the density-temperature range of 0.387 - 5.35 g/cc and 500 K - 1.28x10^8 K. One coherent equation of state (EOS) is derived by combining DFT-MD data at lower temperatures with PIMC results at higher temperatures. Good agreement between both techniques is found in an intermediate temperature range. For the highest temperatures, the PIMC results converge to the Debye-Hueckel limiting law. In order derive the entropy, a thermodynamically consistent free energy fit is introduced that reproduces the internal energies and pressure derived from the first-principles simulations. The equation of state is presented in form of a table as well as a fit and is compared with chemical models. In addition, the structure of the fluid is analyzed using pair correlation functions. Shock Hugoniot curves are compared with recent laser shock wave experiments.

description: We present a multi-instrument spectroscopic analysis of the unique Li/Na-rich giant star 25664 in Omega Centauri using spectra acquired with FLAMES-GIRAFFE, X-SHOOTER, UVES and HARPS. Li and Na abundances have been derived from the UVES spectrum using transitions weakly sensitive to non-local thermodynamic equilibrium and assumed isotopic ratio. This new analysis confirms the surprising Li and Na abundances of this star (A(Li) =+2.71+-0.07 dex, [Na/Fe]=+1.00+-0.05 dex). Additionally, we provide new pieces of evidence for its chemical characterisation. The 12C/13C isotopic ratio (15+-2) shows that this star has not yet undergone the extra-mixing episode usually associated with the red giant branch bump. Therefore, we can rule out the scenario of efficient deep extra-mixing during the red giant branch phase envisaged to explain the high Li and Na abundances. Also, the star exhibits high abundances of both C and N ([C/Fe]=+0.45+-0.16 dex and [N/Fe]=+0.99+-0.20 dex), not compatible with the typical C-N anticorrelation observed in globular cluster stars. We found evidence of a radial velocity variability in 25664, suggesting that the star could be part of a binary system, likely having accreted material from a more massive companion when the latter was evolving in the AGB phase. Viable candidates for the donor star are AGB stars with 3-4 Msun and super-AGB stars (~7-8 Msun), both able to produce Li- and Na-rich material. Alternatively, the star could be formed from the pure ejecta of a super-AGB stars, before the dilution with primordial gas occurs.

The role of myth in the modern novel : an examination of Federigo Tozzi’s Il Podere
Creators: name: Cividino, Ezio
Publisher: name: University of British Columbia
Year: 2010

description: This thesis consists of an examination of a selected number of myth views. It is suggested that myth is not the private preserve of any one academic domain, but rather belongs to all disciplines. If confusion exists over its definition it is due to 'limited views' engendered by diverse schools. It is further suggested that developed definitions hold no sway over myth's function. To demonstrate the above points, this thesis examines the novel II podere. by Federigo Tozzi, and also attempts to point out that: l) Individual growth is not haphazard but follows a mythic structure, 2) myth determines societal superstructures, and 3) mythic analysis of literature, especially the 'psychological novel', will not only add to the richness of literary understanding but also offer artistic depth. It further suggests that myth research should not be taken as finite, and proposes that literary critics closely follow cultural change and monitor new research, especially the concept of 'reality' as held by other cultures.

description: We investigate the light-cone wave functions and leading-twist distribution amplitudes for the nucleon and $Δ$ baryon within the framework of the chiral quark-soliton model. The baryon wave function consists of the valence quark and vacuum wave functions. The vacuum wave functions generate all possible higher Fock states by expanding them. We find that it is essential to consider the five-quark component and relativistic corrections to evaluate the distribution amplitudes of the nucleon and $Δ$ isobar. Having taken into account them, we derive the distribution amplitudes. The results are in good agreement with the lattice data.

description: We investigate the joint (separable) numerical range of multiple measurements, i.e., the regions of expectation values accessible with (separable) quantum states for given observables. This not only enables efficient entanglement detection, but also sheds light on the geometry of the set of quantum states. More precisely, in an experiment, if the confidence region for the obtained data and the separable numerical range are disjoint, entanglement is reliably detected. Generically, the success of such an experiment is more likely the smaller the separable numerical range is compared to the standard numerical range of the observables measured. We quantify this relation using the ratio between these two volumes and show that it cannot be arbitrarily small, giving analytical bounds for any number of particles, local dimensions as well as number of measurements. Moreover, we explicitly compute the volume of separable and standard numerical range for two locally traceless two-qubit product observables, which are of particular interest as they are easier to measure in practice. Furthermore, we consider typical volume ratios for generic observables and extreme instances.

description: The possible dependence of fundamental couplings and mass ratios on the gravitational potential has been bounded by comparing atomic clock frequencies over Earth's elliptical orbit. Here we evaluate bounds on such dependence from E"otv"os-type experiments that test the Weak Equivalence Principle, including previously neglected contributions from nuclear binding energy. We find that variations of fundamental parameters correlated with the gravitational potential are bounded at 10^-8--10^-9, an improvement of 2--3 orders of magnitude over atomic clock bounds.

title: Participatory Guarantee System for the quality of farmers’ seeds for Community Seed Banks in Colombia

Subjects: subject: AGROVOC: Income generation

description: In Colombia, as in many other countries, farmers' seeds are not legally recognized. To address this, Semillas de Identidad—a network of seed guardians made up of 10,000 families organized into 500 seed banks—has developed a system to safeguard seed quality. In 2015, a collaboration between NGOs, networks, and community seed banks led to the adaptation of participatory guarantee systems (PGS). This community-based quality assurance system emphasizes social control and knowledge building.
Like traditional third-party certification systems, PGS aims to provide a credible quality guarantee for farmers and gardeners. To qualify for PGS certification, seeds must be cultivated without synthetic inputs, such as chemical pesticides and fertilizers. They must also meet other conditions, including having a good germination rate and being free from diseases and contamination by genetically modified organisms.
Seeds approved by the PGS can display a specific label, allowing farmers to generate additional income by selling these certified seeds. More importantly, this labeling conveys a political message: it demonstrates that farmers can produce high-quality seeds and ensure their own quality standards. This initiative contributes to the network's broader political goals of increasing recognition for farmers' seed systems and respecting farmers' rights within Colombia's seed regulations. The PGS system offers an alternative to the state's certification process and has expanded to several regions, including Córdoba, Sucre, Bolívar, Antioquia, Caldas, Risaralda, Quindío, Cauca, Valle, Nariño, and Boyacá.

Effect of CuO chains on the local density of states in the vortex phase of YBa_2Cu_3O_7

description: We examine the effects of the CuO chains on the density of states in the vortex phase in YBa_2Cu_3O_7, via a calculation based on the tight-binding proximity model. In this model, chain superconductivity results from single-electron hopping between the intrinsically-normal chains and intrinsically-superconducting CuO_2 planes. The calculations are based on self-consistent solutions of the Bogolyubov-de Gennes equations for a bilayer consisting of a single CuO_2 layer and a single CuO chain layer. We find that, in addition to the dispersing resonances found in single-layer models, the chains introduce a second set of dispersing resonances associated with the induced gap in the chain layer. These new resonances are highly anisotropic and distort the vortex core shape.

description: In this decade astronomy is undergoing a paradigm shift to handle data from next generation observatories such as the Square Kilometre Array (SKA) or the Vera C. Rubin Observatory (LSST). Producing real time data streams of up to 10 TB/s and data products of the order of 600 Pbytes/year, the SKA will be the biggest civil data producing machine of the world that demands novel solutions on how these data volumes can be stored and analysed. Through the use of complex, automated pipelines the provenance of this real time data processing is key to establish confidence within the system, its final data products, and ultimately its scientific results. The intention of this paper is to lay the foundation for making an automated provenance generation tool for astronomical/data-processing pipelines. We therefore present a use case analysis, specific to the astronomical needs which addresses the issues of trust and reproducibility as well as other ulterior use cases which are of interest to astronomers. This analysis is subsequently used as the basis to discuss the requirements, challenges, and opportunities involved in designing both the tool and the associated provenance model.

Semiconducting character of LaN: magnitude of the band gap, and origin of the electrical conductivity

description: Lanthanum nitride (LaN) has attracted research interest in catalysis due to its ability to activate the triple bonds of N$_2$ molecules, enabling efficient and cost-effective synthesis of ammonia from N$_2$ gas. While exciting progress has been made to use LaN in functional applications, the electronic character of LaN (metallic, semi-metallic, or semiconducting) and magnitude of its band gap have so far not been conclusively determined. Here, we investigate the electronic properties of LaN with hybrid density functional theory calculations. In contrast to previous claims that LaN is semi-metallic, our calculations show that LaN is a direct-band-gap semiconductor with a band-gap value of 0.62 eV at the X point of the Brillouin zone. The dispersive character of the bands near the band edges leads to light electron and hole effective masses, making LaN promising for electronic and optoelectronic applications. Our calculations also reveal that nitrogen vacancies and substitutional oxygen atoms are two unintentional shallow donors with low formation energies that can explain the origin of the previously reported electrical conductivity. Our calculations clarify the semiconducting nature of LaN and reveal candidate unintentional point defects that are likely responsible for its measured electrical conductivity.

description: 34. Sesiidae – clearwing moths Small to medium sized (15–40 mm wingspan) moths with narrow wings. In most species the wings are at least partly transparent, with the scales primarily restricted to the veins and wing margins. Adults of many species have brightly colored bodies and are convincing mimics of bees or wasps. These moths are diurnal, and at least some species visit flowers, but they are rarely observed. Most recent collecting has been done with traps baited with synthetic pheromones. Larvae are stem and root borers in woody plants and larger herbs. A few species are pests of ornamental and orchard trees and of berry crop plants. Over 1100 species of sesiids are known worldwide, including 128 species from North America; 26 species are reported from AB. Th e family is fairly well known in North America; Eichlin and Duckworth (1988) revised the entire family, and five more species have been added since then.

description: The most desirable goal in tertiary education is training students to become autonomous learners to pursue life-long learning. This study investigated teachers’ and students’ perceptions about autonomous English language learning. The participants were selected from 2 national universities, and 1 regional university during the 1st semester of the school year 2020-2021. Particularly, 370 teacher participants out of 5,000, together with 392 student respondents out of 20,000 were chosen by the judgmental sampling technique using Slovin’s formula (CL=±5%). Questionnaires were administered to 762 participants via their email addresses embedded with the active link of Google form and handouts. The questionnaires adapted from Ustunluoglu (2009) with the piloted Cronchbatch’s alpha liability ranged 0.9α≥0.8 included 3 contrastive sections such as responsibilities, abilities, and activities. Descriptive frequencies and mean were employed to differentiate the standpoints of respondents in terms of learner autonomy. The results reveal that students surrendered their responsibilities to their teachers’ roles while teachers considered themselves as dominant figures who were responsible for students in learner autonomy. Furthermore, teachers and students mostly agreed that students had the ability to do well in autonomous language learning if given the chance. The finding shows a mismatch with teachers claiming that their students participated in autonomous learning activities at a moderate extent whereas students remarked they highly took part in them. It is necessary to transform teachers’ responsibilities to students’ accountability. Besides, the adjustment of curriculum and practical pedagogical approaches should be applied, and the encouragement for students to use authentic learning materials or communicate with foreigners in English should be promoted.

description: The current study aims to explore postgraduate students' level of electronic search skills at the University of Hail. To achieve the objective of the study, a 34-item questionnaire is developed and the descriptive analytical approach is adopted. The study sample consists of (62) male and female postgraduate students randomly selected from all faculties of the university during the first semester of the academic year 2019/2020. The results of the study show that the level of electronic search skills among postgraduates is medium. The results also show that there is a statistically significant difference at the level of electronic search skills due to the variable of the cumulative average in favor of a very good average. Besides, the results also show that there are no statistically significant differences at the level of electronic search skills due to the variables of the student's specialization in their first university degree or due to gender. The study recommends raising the level of postgraduate students’ participation in electronic search by providing an electronic learning environment to bridge the gap they have by offering electronic courses that refine and develop their practical and search skills.

Subjects: English; Language; Culture; Education system; Linguistic Hegemony

description: This paper critically analyzes the use of the English language in Pakistani universities and its implications for students. The data for this paper is drawn from qualitative research conducted in two universities in Islamabad - the federal capital of Pakistan. Semi-structured interviews were conducted with 56 participants including teachers and students. The findings illustrate that students struggled to learn and use English in the academic spaces. This was especially true for students from rural backgrounds and those trained in public schools. Yet, despite such difficulties, English was believed to be a powerful language and its significance was acknowledged in order for them to operate as global citizens. Nevertheless, besides the promises associated with the English language, the threats and dangers to the local culture and local languages were also a concern for some participants. It was believed that the foreign culture in the academic spaces was promoting linguistic and cultural hegemony. The paper emphasises the need to make efforts for the maintenance and promotion of the Urdu language despite the dynamics introduced by the hegemony of the English language.
