description: In this work, a numerical approach to investigate the room temperature luminescence emission from core/shell nanowire is presented where GaN quantum discs (QDiscs), periodically distributed in AlxGa1-xN nanowire, is considered as core and AlxGa1-xN as shell. Thin disk shaped (Ring shaped) n-doped region has been placed at the GaN/ AlxGa1-xN (AlxGa1-xN /air) interface in AlxGa1-xN region in axial (radial) directions. To obtain energy levels and related wavefunctions, self-consistent procedure has been employed to solve Schrodinger-Poisson equations with considering the spontaneous and piezoelectric polarization. Then luminescence spectrum is studied in details to recognize the parameters influent in luminescence. The results show that the amount of doping, size of QDiscs and theirs numbers have remarkable effects on the band to band luminescence emission. Our numerical calculations gives some insights into the luminescence emission of core/shell nanowire and exhibits a useful tool to analyze findings in experiments.

description: With the conditional support of data and principles, wave energy collection devices can use simple components, anti-erosion materials, and energy collection in low-wave sea state areas. In operation, the device can transmit electricity to the shore for electrolytic hydrogen and hydrogen liquefaction of seawater by taking advantage of the location factor. For example, citing data from the 71st edition of the BP World Energy Statistics Yearbook in 2022, Japan will consume an average of 3.357 million barrels of petroleum liquid fuel per day in 2021, and the current electrolysis energy consumption per cubic meter of hydrogen is as low as 2.23 KW • H. Based on the calorific value data alone, more than 870000 wave energy acquisition devices have been completed, using 3*3*2 (3 meters in length, 3 meters in width, and 2 meters in height) water surface floating bodies. Each device occupies 9 square meters at sea level. When the wave height in the sea area meets the stroke of 1 meter above and below the floating bodies, the electrolytic hydrogen output produced by the electricity supply can replace Japan's daily oil consumption and become a substitute for Japanese oil as liquid fuel.

description: A long-standing hypothesis in evolutionary biology is that the evolution of resource specialization can lead to an evolutionary dead end, where specialists have low diversification rates and limited ability to evolve into generalists. In recent years, advances in comparative methods investigating trait-based differences associated with diversification have enabled more robust tests of this idea and have found mixed support. We test the evolutionary dead end hypothesis by estimating net diversification rate differences associated with nest site specialization among 3,224 species of passerine birds. In particular, we test whether the adoption of hole-nesting, a nest site specialization that decreases predation, results in reduced diversification rates relative to nesting outside of holes. Further, we examine whether evolutionary transitions to the specialist hole-nesting state have been more frequent than transitions out of hole-nesting. Using diversification models that accounted for background rate heterogeneity and different extinction rate scenarios, we found that hole-nesting specialization was not associated with diversification rate differences. Furthermore, contrary to the assumption that specialists rarely evolve into generalists, we found that transitions out of hole-nesting occur more frequently than transitions into hole-nesting. These results suggest that interspecific competition may limit adoption of hole-nesting, but that such competition does not result in limited diversification of hole-nesters. In conjunction with other recent studies using robust comparative methods, our results add to growing evidence that evolutionary dead ends are not a typical outcome of resource specialization.

description: We examine the dynamics associated with the miscibility-immiscibility transition of trapped two-component Bose-Einstein condensates (TBECs) of dilute atomic gases in presence of vortices. In particular, we consider TBECs of Rb hyperfine states, and Rb-Cs mixture. There is an enhancement of the phase-separation when the vortex is present in both condensates. In the case of a singly charged vortex in only one of the condensates, there is enhancement when the vortex is present in the species which occupy the edges at phase-separation. But, suppression occurs when the vortex is in the species which occupies the core region. To examine the role of the vortex, we quench the inter-species interactions to propel the TBEC from miscible to immiscible phase, and use the time dependent Gross-Pitaevskii equation to probe the phenomenon of phase-separation. We also examine the effect of higher charged vortex.

Mitigating the Environmental Impact of Cattle and Sheep: Animal Genetics and Farmers' Readiness for Uptake, 2010-2011
Creators: name: Bruce, A.
Publisher: name: UK Data Service
Year: 2015

description: This is a qualitative data collection. Global warming is often thought as being caused by energy production but the second largest contributor is animal production, with methane produced by cows and sheep a key component. One obvious solution is to reduce meat and milk consumption but this is unlikely to be acceptable to everyone. Moreover, grass-fed animals (such as cows and sheep) can provide other benefits than food, such as managing biodiversity. The UK has a good climate for producing grass and many of the upland regions of the UK cannot be used for cultivating anything other than grass. Grazing animals therefore provide the backbone of many rural communities.

 A range of different animal breeding technologies, such as traditional genetic methods to improve production efficiency or using biotechnology tools such as semen sexing and even potentially genetic modification, could be used to mitigate the global warming impact of farm livestock. Adoption of these technologies, however, may be limited by the willingness of farmers to purchase these animals.

 To this end, 42 semi-structured interviews were undertaken (of which 29 are included in this data collection) with sheep and beef cattle farmers across the UK and with industry representatives.

description: Twenty years ago, Rovelli proposed that the degeneracy of black hole (i.e. the exponential of the Bekenstein-Hawking entropy) is given by the number of ways the black hole horizon area can be expressed as a sum of unit areas. However, when counting the sum, one should treat the area quanta on the black hole horizon as distinguishable. This distinguishability of area quanta is noted in Rovelli's paper. Building on this idea, we derive that the Hawking radiation spectrum is not given by Planck radiation spectrum (i.e., Bose-Einstein distribution) but given by Maxwell-Boltzmann distribution.

description: This is a qualitative data collection. To understand the processes and motivations behind changes in labour market behaviour during periods of economic recession, this research project recorded the experiences and views of couple-households exposed to job loss in the Great Recession. Conducted as part of a larger ESRC-funded quantitative project, qualitative interviews were carried out with a purposive sample derived from the Understanding Society Innovation Panel. (The Understanding Society Innovation Panel is an annual panel survey that collects a wide range of information about the economic and social circumstances of those living in 1500 households across Britain.) Using the wealth of longitudinal information in the Understanding Society Innovation Panel, a sampling frame of approximately 150 couple households was identified where someone had either lost their job or was working reduced hours in the period 2008 to 2011. A carefully selected sample of 17 households were followed up and in-depth interviews were conducted with the couple-member who had experienced job loss and, where possible, their partner. The selection process was designed to assemble a sample reflecting a diverse range of household and family profiles; namely, couples with and without children, older and younger children; the pre-retirement phase; a range of incomes; and labour market areas across England more and less affected by the recession. Wherever feasible, partners were interviewed separately to allow each participant the opportunity to express their personal views most freely. Overall this led to 30 interviews, each of about 45 minutes in length. Fieldwork took place between October 2012 and February 2013 and consent was obtained verbally. The research design incorporates the ability to link the interview transcripts to Understanding Society Innovation Panel survey data for future combined analysis of qualitative and quantitative material, subject to Special Licence.

Year: 2015

description: This is a qualitative data collection. In recent years a range of often debates about have demonstrated the potential for new technologies to become the focus of widespread concern and anxiety. The Strategic Science project considered the social ramifications of new technology through an examination of how their development is shaped by political and policy priorities and by the methods used to support and coordinate research. Focusing particularly on the development of nanotechnology and synthetic biology – two areas of current research and development – the project explored how research in both fields is shaped by research funding programmes and research council initiatives. The research included ethnographic observation of research council initiatives, interviews with research council staff and science policy practitioners and desk-based research. The project found that though government policy and research council strategies have an important influence on the development of research in new fields that this process is not well understood. In addition to the formal targets and policy priorities that structure research practice, the research revealed the wider use a range of more informal techniques for developing research agendas, research communities and definitions in emerging fields. The project also revealed that this informal process is a social and political one that frames the wider goals and ambitions of emerging fields of research. The implications of the project are that the interface between scientific practice and the strategies of research funding bodies are a key site for understanding the broader societal dimensions of new technologies.

 The collection consist of 49 qualitative research interview transcripts.

Résumé : Ce projet d’étude porte sur les élèves ayant droit à une éducation francophone en milieu minoritaire, mais qui s’inscrivent dans les programmes canadiens alternatifs d’immersion française conçus pour l’apprenant de langue additionnelle. Cette thématique est importante parce qu’il y a un manque de recherches sur les défis de leur inclusion en immersion française ainsi que sur les adaptations de la part du système scolaire pour répondre à leurs besoins spécifiques. Les études proposent une recension des écrits pour mieux comprendre les enjeux systématiques, du ministère de l’Éducation jusqu’aux enseignants d’immersion française dans la salle de classe, qui influencent le choix de ce contexte éducatif immersif et l’expérience scolaire possible de l’élève ayant droit. L’objectif est de soutenir une compréhension de la complexité rattachée au profil d’élève ayant droit francophone pour que le système éducatif puisse mieux répondre à ses besoins s’il choisit l’immersion française.

Abstract: This research project focuses on rights holder students entitled to Francophone education in a minority setting, but who enroll in alternative Canadian French immersion programs designed for the additional language learner. This theme is important because there is a lack of research on the challenges of their inclusion in French immersion as well as the adaptations on the part of the school system to meet their specific needs. The study offers a literature review to better understand the existing systematic issues from the Ministry of Education to the classroom French immersion teachers that influence the choice of the immersion educational context and the possible school experience of the student. The objective is to support an understanding of the complexity attached to the profile of a Francophone rights holder student so that the education system can better meet their needs if they choose French immersion.

description: We present a VLT/MUSE survey of lensed high-redshift galaxies behind the z=0.77 cluster RCS0224-0002. We study the detailed internal properties of a highly magnified (μ~29) z=4.88 galaxy seen through the cluster. We detect wide-spread nebular CIVλλ1548,1551Å emission from this galaxy as well as a bright Lyα halo with a spatially-uniform wind and absorption profile across 12 kpc in the image plane. Blueshifted high- and low-ionisation interstellar absorption indicate the presence of a high-velocity outflow (Δv~300 km/s) from the galaxy. Unlike similar observations of galaxies at z=2-3, the Lyα emission from the halo emerges close to the systemic velocity - an order of magnitude lower in velocity offset than predicted in "shell"-like outflow models. To explain these observations we favour a model of an outflow with a strong velocity gradient, which changes the effective column density seen by the Lyα photons. We also search for high-redshift Lyα emitters and identify 14 candidates between z=4.8-6.6, including an over-density at z=4.88, of which only one has a detected counterpart in HST/ACS+WFC3 imaging.

Preliminary orbits with line-of-sight correction for LEO satellites observed with radar

description: We propose a method to account for the Earth oblateness effect in preliminary orbit determination of satellites in low orbits with radar observations. This method is an improvement of the one described in (Gronchi et al 2015), which uses a pure Keplerian dynamical model. Since the effect of the Earth oblateness is strong at low altitudes, its inclusion in the model can sensibly improve the initial orbit, giving a better starting guess for differential corrections and increasing the chances to obtain their convergence. The input set consists of two tracks of radar observations, each one composed of at least 4 observations taken during the same pass of the satellite. A single observation gives the topocentric position of the satellite, where the range is very accurate, while the line of sight direction is poorly determined. From these data we can compute by a polynomial fit the values of the range and range rate at the mean epochs of the two tracks. In order to obtain a preliminary orbit we wish to compute the angular velocities, that is the rate of change of the line of sight. In the same spirit of (Gronchi et al 2015), we also wish to correct the values of the angular measurements, so that they fit the selected dynamical model if the same holds for the radial distance and velocity. The selected model is a perturbed Keplerian dynamics, where the only perturbation included is the secular effect of the $J_2$ term of the geopotential. The proposed algorithm models this problem with 8 equations in 8 unknowns.

description: We present Monte Carlo (MC) simulation studies of phase separation in binary (AB) mixtures with bond-disorder that is introduced in two different ways: (i) at randomly selected lattice sites and (ii) at regularly selected sites. The Ising model with spin exchange (Kawasaki) dynamics represents the segregation kinetics in conserved binary mixtures. We find that the dynamical scaling changes significantly by varying the number of disordered sites in the case where bond-disorder is introduced at the randomly selected sites. On the other hand, when we introduce the bond-disorder in a regular fashion, the system follows the dynamical scaling for the modest number of disordered sites. For higher number of disordered sites, the evolution morphology illustrates a lamellar pattern formation. Our MC results are consistent with the Lifshitz-Slyozov (LS) power-law growth in all the cases.

description: Despite advances in multi-modal treatment approaches, clinical outcomes of patients suffering from PAX3-FOXO1 fusion oncogene-expressing alveolar rhabdomyosarcoma (ARMS) remain dismal. Here we show that PAX3-FOXO1expressing ARMS cells are sensitive to pharmacological ataxia telangiectasia and Rad3 related protein (ATR) inhibition. Expression of PAX3-FOXO1 in muscle progenitor cells is not only sufficient to increase sensitivity to ATR inhibition, but PAX3-FOXO1-expressing rhabdomyosarcoma cells also exhibit increased sensitivity to structurally diverse inhibitors of ATR. Mechanistically, ATR inhibition leads to replication stress exacerbation, decreased BRCA1 phosphorylation and reduced homologous recombination-mediated DNA repair pathway activity. Consequently, ATR inhibitor treatment increases sensitivity of ARMS cells to PARP1 inhibition in vitro, and combined treatment with ATR and PARP1 inhibitors induces complete regression of primary patient-derived ARMS xenografts in vivo. Lastly, a genome-wide CRISPR activation screen (CRISPRa) in combination with transcriptional analyses of ATR inhibitor resistant ARMS cells identifies the RAS-MAPK pathway and its targets, the FOS gene family, as inducers of resistance to ATR inhibition. Our findings provide a rationale for upcoming biomarker-driven clinical trials of ATR inhibitors in patients suffering from ARMS.

description: In today's education systems, there is a deep concern about the importance of teaching code and computer programming in schools. Moving digital learning from a simple use of tools to understanding the processes of the internal functioning of these tools is an old / new debate originated with the digital laboratories of the 1960. Today, it is emerging again under impulse of the large - scale public sphere digitalization and the new constructivist education theories. Teachers and educators discuss not only the viability of code teaching in the classroom, but also the intellectual and cognitive advantages for students. The debate thus takes several orientations and is resourced in the entanglement of arguments and interpretations of any order, technical, educational, cultural, cognitive and psychological. However, that phenomenon which undoubtedly augurs for a profound transformation in the future models of learning and teaching , is predicting a new and almost congenital digital humanism

description: Entanglement distribution between distant parties is an essential component to most quantum communication protocols. Unfortunately, decoherence effects such as phase noise in optical fibers are known to demolish entanglement. Iterative (multistep) entanglement distillation protocols have long been proposed to overcome decoherence, but their probabilistic nature makes them inefficient since the success probability decays exponentially with the number of steps. Quantum memories have been contemplated to make entanglement distillation practical, but suitable quantum memories are not realised to date. Here, we present the theory for an efficient iterative entanglement distillation protocol without quantum memories and provide a proof-of-principle experimental demonstration. The scheme is applied to phase-diffused two-mode-squeezed states and proven to distill entanglement for up to three iteration steps. The data are indistinguishable from those an efficient scheme using quantum memories would produce. Since our protocol includes the final measurement it is particularly promising for enhancing continuous-variable quantum key distribution.

description: Between May 1978 and December 1983 the sociologist Ray Pahl conducted seven extensive interviews with a couple from Sheppey that he called 'Linda' and 'Jim'. The interviews evolved into an intensive, profoundly human story of how a family used to 'getting by' (though never 'affluent') coped with the hardships and indignities of long-term reliance on welfare benefits. Perhaps inevitably, fascinating aspects of Linda and Jim's testimony were left unused in Divisions of Labour, primarily because they were marginal to Pahl's principal areas of interest. These edited extracts from the interview transcripts focus on questions of identity and the emotional experience of unemployment. Changing the lens through which we study Linda and Jim does not invalidate Pahl's earlier arguments, but it can offer different insights into what it meant to be unemployed in Thatcher's Britain.

description: Decisions related to controversial problems in natural resource management receive the greatest support when they account for multiple objectives of stakeholders in a structured and transparent fashion. In the United States, management of free-roaming horses (Equus caballus; horses) is a controversial multiple-objective problem because disparate stakeholder groups have varying objectives and opinions about how to manage fast-growing horse populations in ways that sustain both natural ecosystems and healthy horses. Despite much decision-support research on management alternatives that prevent excessive population size or cost, horse management decisions still receive resistance from a variety of stakeholder groups, potentially because decisions fail to explicitly or transparently account for multiple objectives of diverse stakeholders. Here, we used a predictive model for horse populations to evaluate the degree to which alternative management strategies involving removals and fertility control treatment with the immunocontraceptive vaccine PZP-22 maximize 4 objectives in horse management: maximize ecosystem health, maximize horse health, minimize effects on horse behavior, and minimize management cost. We simulated scenarios varying in management action, frequency, magnitude, and starting population size over a 10-year interval and evaluated scenario performance with a weighted multiple-objective utility reward function. Management involving high-magnitude removals along with PZP-22 treatment generally outperformed other alternatives by achieving higher reward relative to alternatives in 2 scenario analyses. Simulation of 1,372 scenarios at 5 starting population sizes generally found that management with biannual removals and 2 doses of PZP-22 treatment for half of eligible females during years 1 and 5 generated the most rewarding outcomes. However, a removal scenario with more frequent PZP-22 application generated the greatest reward when starting population size was already within target population size range. Our paper demonstrates how values and objectives of diverse stakeholders can be used to support management decisions in ways that might lead to greater acceptance of decisions by a broad array of stakeholder groups.

description: While the U.S. food system has been largely able to maintain operations and provide consumers with the variety of foods they desire since the Coronavirus (COVID-19) pandemic began, U.S. households faced sharply higher food prices for many staple items, especially meat in 2020. In this study, U.S. households’ meat purchases at retail stores for at-home consumption during the COVID-19 pandemic are examined and compared with those before the virus outbreak.

description: The distribution of metals in the intracluster medium (ICM) of galaxy clusters provides valuable information on their formation and evolution, on the connection with the cosmic star formation and on the effects of different gas processes. By analyzing a sample of simulated galaxy clusters, we study the chemical enrichment of the ICM, its evolution, and its relation with the physical processes included in the simulation and with the thermal properties of the core. These simulations, consisting of re-simulations of 29 Lagrangian regions performed with an upgraded version of the SPH GADGET-3 code, have been run including two different sets of baryonic physics: one accounts for radiative cooling, star formation, metal enrichment and supernova (SN) feedback, and the other one further includes the effects of feedback from active galactic nuclei (AGN). In agreement with observations, we find an anti-correlation between entropy and metallicity in cluster cores, and similar radial distributions of heavy-element abundances and abundance ratios out to large cluster-centric distances (~R180). In the outskirts, namely outside of ~0.2R180, we find a remarkably homogeneous metallicity distribution, with almost flat profiles of the elements produced by either SNIa or SNII. We investigated the origin of this phenomenon and discovered that it is due to the widespread displacement of metal-rich gas by early (z>2-3) AGN powerful bursts, acting on small high-redshift haloes. Our results also indicate that the intrinsic metallicity of the hot gas for this sample is on average consistent with no evolution between z=2 and z=0, across the entire radial range.

description: In this paper we study the cosmic acceleration for five dynamical dark energy models whose equation of state varies with redshift. The cosmological parameters of these models are constrained by performing a MCMC analysis using mainly gas mass fraction, $f_{gas}$, measurements in two samples of galaxy clusters: one reported by Allen et al. (2004), which consists of $42$ points spanning the redshift range $0.05

description: The explosive growth of the location-enabled devices coupled with the increasing use of Internet services has led to an increasing awareness of the importance and usage of geospatial information in many applications. The navigation apps (often called Maps), use a variety of available data sources to calculate and predict the travel time as well as several options for routing in public transportation, car or pedestrian modes. This paper evaluates the pedestrian mode of Maps apps in three major smartphone operating systems (Android, iOS and Windows Phone). In the paper, we will show that the Maps apps on iOS, Android and Windows Phone in pedestrian mode, predict travel time without learning from the individual's movement profile. In addition, we will exemplify that those apps suffer from a specific data quality issue which relates to the absence of information about location and type of pedestrian crossings. Finally, we will illustrate learning from movement profile of individuals using various predictive analytics models to improve the accuracy of travel time estimation.
Inertial and non-inertial microfluidics of deformable particles, and red blood cell-resolved capillary network hemodynamics with machine-learning applications

description: A computational study and a machine learning approach are used for the numerical simulation of healthy and stiffer red blood cells and the prediction of the hemodynamics of blood flow in a microvascular network. We utilized the immersed boundary method to simulate blood flow in the complex microvasculature and continuous immersed boundary method to capture cell deformation. Two common machine learning approaches namely, regression and classification are employed for prediction of volume flow rate and hematocrit in the entire microvasculature. In the first part of this thesis cross stream migration of a capsule in a three-dimensional curved vessel is investigated in the presence and absence of inertia. For these two cases the equilibrium location of the capsule is determined. The effect of different parameters including vessel curvature, capsule deformability, and tube Reynolds number is considered. We also study lateral migration of capsule in a U-shaped vessel to consider the effect of change in the curvature of vessel. In the second part of this study a cross–stream migration of a deformable capsule in curved microchannel of square and rectangular section under inertial and non-inertial transport is studied. We discuss the different focusing behavior in these two regimes due to the interplay between inertia, deformation, shear gradient, streamline curvature and secondary flow. We also investigate the effect of channel width and height on the capsule equilibrium location. In the third part of this thesis, the influence of reduction in cell deformability on microvascular hemodynamics is established. Blood flow including thousands of red blood cells in a physiologically realistic microvascular network is simulated. We study how reduced RBCs deformability can influence RBC trafficking with significant and heterogeneous change in hematocrit. We quantify the change in RBC partitioning, perfusion, vascular resistance, and wall shear stress due to the change in RBCs deformability.Finally, we investigate the applicability of machine learning (ML) techniques to predict blood flow and RBC distributions in physiologically realistic vascular networks. We acquire data from high-fidelity simulations of deformable RBC suspension flowing in the networks. With the flow and hematocrit specified at an inlet of a vasculature, the ML models predict the time-averaged flow rate and RBC distributions in the entire network, time-dependent flow rate and hematocrit in each vessel and vascular bifurcation in isolation over a long time, and finally, simultaneous spatially and temporally evolving quantities through the vessel hierarchy in the networks.

description: The discovery of Proxima b, a terrestrial temperate planet, presents the opportunity of studying a potentially habitable world in optimal conditions. A key aspect to model its habitability is to understand the radiation environment of the planet in the full spectral domain. We characterize the X-rays to mid-IR radiative properties of Proxima with the goal of providing the top-of-atmosphere fluxes on the planet. We also aim at constraining the fundamental properties of the star. We employ observations from a large number of facilities and make use of different methodologies to piece together the full spectral energy distribution of Proxima. In the high-energy domain, we pay particular attention to the contribution by rotational modulation, activity cycle, and flares so that the data provided are representative of the overall radiation dose received by the atmosphere of the planet. We present the full spectrum of Proxima covering 0.7 to 30000 nm. The integration of the data shows that the top-of-atmosphere average XUV irradiance on Proxima b is 0.293 W m^-2, i.e., nearly 60 times higher than Earth, and that the total irradiance is 877+/-44 W m^-2, or 64+/-3% of the solar constant but with a significantly redder spectrum. We also provide laws for the XUV evolution of Proxima corresponding to two scenarios. Regarding the fundamental properties of Proxima, we find M=0.120+/-0.003 Msun, R=0.146+/-0.007 Rsun, Teff=2980+/-80 K, and L=0.00151+/-0.00008 Lsun. In addition, our analysis reveals a ~20% excess in the 3-30 micron flux of the star that is best interpreted as arising from warm dust in the system. The data provided here should be useful to further investigate the current atmospheric properties of Proxima b as well as its past history, with the overall aim of firmly establishing the habitability of the planet.

description: Proper motions (PMs) are crucial to fully understand the internal dynamics of globular clusters (GCs). To that end, the Hubble Space Telescope (HST) Proper Motion (HSTPROMO) collaboration has constructed large, high-quality PM catalogues for 22 Galactic GCs. We highlight some of our exciting recent results: the first directly-measured radial anisotropy profiles for a large sample of GCs; the first dynamical distance and mass-to-light (M/L) ratio estimates for a large sample of GCs; and the first dynamically-determined masses for hundreds of blue-straggler stars (BSSs) across a large GC sample.

description: Antarctic krill is a large, long-lived pelagic crustacean that is widely distributed around Antarctica and is among the most abundant wild animal species on Earth by biomass. Krill form dense swarms, are the main food source for many predators, and play important roles in biogeochemical cycles.
However, crucial gaps remain in our understanding of krill population dynamics. Resolving these uncertainties will be fundamental to improving management if the fishery targeting this species is to expand sustainably while fulfilling CCAMLR’s conservation goals.
