description: Enlarged planar Galilean symmetry, built of both space-time and field variables and also incorporating the ``exotic'' central extension is introduced. It is used to describe non-relativistic anyons coupled to an electromagnetic field. Our theory exhibits an anomalous velocity relation of the type used to explain the Anomalous Hall Effect. The Hall motions, characterized by a Casimir of the enlarged algebra, become mandatory for some critical value(s) of the magnetic field. The extension of our scheme yields the semiclassical effective model of the Bloch electron.

description: This paper studies the diffusion of greenhouse agriculture in a watershed in the northern uplands of Thailand by applying econometrics and agent-based modeling in combination. Adoption has been rapid by farmers in the central valley of the watershed, while farmers at higher altitudes, lacking transferable land titles that could serve as mortgage collateral, have been unable to obtain loans for greenhouse investment. The objectives of the paper are both methodological and empirical. On the methodological side, it shows that econometrically estimated models of farm household behavior are useful to design and to parameterize an agent-based model. On the empirical side, simulation results show that if mortgage collateral would not be required, then adoption in the upper part of the watershed could reach nearly 77 percent of farm households by 2020, as compared to about 36 percent under current conditions. Further results suggest a significant increase in incomes related to the innovation and a substantially greater irrigation water use, especially in the central part. As bell pepper under greenhouses has replaced pesticide-intensive chrysanthemum, it has declined average levels of pesticide use. Nevertheless, pesticide use is high and farmers are struggling to control pests, which raises questions about the long-term sustainability of the innovation.
Texture zeros flavor neutrino mass matrix and triplet Higgs models

description: One- and two-zero textures for the flavor neutrino mass matrix have been successful in explaining mixing in the neutrino sector. Conservatively, six cases of one-zero textures and seven cases of two-zero textures are compatible with observations. We show that one case may be the most natural in the one- and two-zero textures schemes if tiny neutrino masses are generated by the type-II seesaw mechanism in triplet Higgs models.

Far-right Violence during the Spanish Transition (1973-1982)
Creators: name: Gómez Fernández, Eva
Publisher: name: Zenodo
Year: 2024

description: Between 1973 and 1982, several far-right groups in Spain engaged in various forms of violence: identity-based violence, uncontrolled violence, and terrorist violence. These actions were characterized by armed spontaneity and police permissiveness. The objective of this violence was to undermine the democratic order. In addressing this article, we have relied on secondary sources from newspaper archives with varying ideological perspectives.
General superposition states associated to the rotational and inversion symmetries in the phase space

description: The general quantum superposition states containing the irreducible representation of the $n$-dimensional groups associated to the rotational symmetry of the $n$-sided regular polygon i.e. the cyclic group ($C_n$ ) and the rotational and inversion symmetries of the polygon, i.e. the dihedral group ($D_n$ ) are defined and studied. It is shown that the resulting states form an $n$-dimensional orthogonal set of states which can lead to the finite representation of specific systems. The correspondence between the symmetric states and the renormalized states, resulting from the selective erasure of photon numbers from an arbitrary, noninvariant initial state, is also established. As an example, the general cyclic Gaussian states are presented. The presence of nonclassical properties in these states as subpoissonian photon statistics is addressed. Also, their use in the calculation of physical quantities as the entanglement in a bipartite system is discussed.

description: We present the results of our abundance analysis of Fe, Ni, and O in high S/N, high-resolution VLT/UVES and McDonald/2dcoude spectra of nine dwarfs and three giants in the Hyades open cluster. The difference in Fe abundances derived from Fe II and Fe I lines ([Fe II/H] - [Fe I/H]) and Ni I abundances derived from moderately high-excitation (Chi ~ 4.20 eV) lines are found to increase with decreasing T_eff for the dwarfs. Both of these findings are in concordance with previous results of over-excitation/ionization in cool young dwarfs. Oxygen abundances are derived from the Lambda 6300 [O I] line, with careful attention given to the Ni I blend. The dwarf O abundances are in star-to-star agreement within uncertainties, but the abundances of the three coolest dwarfs (4573 < T_eff < 4834 K) evince an increase with decreasing T_eff. Possible causes for the apparent trend are considered, including the effects of over-dissociation of O-containing molecules. O abundances are derived from the near-UV Lambda 3167 OH line in high-quality Keck/HIRES spectra, and no such effects are found- indeed, the OH-based abundances show an increase with decreasing T_eff, leaving the nature and reality of the cool dwarf [O I]-based O trend uncertain. The mean relative O abundance of the six warmest dwarfs (5075 < T_eff < 5978 K) is [O/H] = +0.14 +/- 0.02, and we find a mean abundance of [O/H] = +0.08 +/- 0.02 for the giants. Thus, our updated analysis of the Lambda 6300 [O I] line does not confirm the Hyades giant-dwarf oxygen discrepancy initially reported by King & Hiltgen (1996), suggesting the discrepancy was a consequence of analysis-related systematic errors....

description: This study estimates the technical, allocative and economic efficiency obtained from the Data Envelopment Analysis (DEA) approach using farm level survey data to a sample of 100 poultry farmers in Bangladesh for the year 2007. The results from the DEA approach show that there is substantial technical, allocative and economic inefficiency in poultry production in Bangladesh. The results of the study reveal that under constant return to scale (CRS) and variable returns to scale (VRS) specification, on average, the farms technical, allocative and economic efficiencies were 88%, 70%, 62% and 89%, 73%, 66% respectively. Thus the results indicate that efficiency scores vary substantially across the sampled farms. To explain some of these variations, the efficiency scores were regressed on the farm’s human capital variables such as farmer’s age, education, main occupation, family members, experience, training received, total farm size and poultry farm size, using a Tobit analysis. The results from the both CRS & VRS approaches indicate that efficiency is significantly influenced by some of the farm’s socio-economic factors. This research finding is valuable for policy makers since it may help to guide policies towards increased efficiency.
Inelastic Meson-Meson Scattering in Hadronic Matter

description: We review studies of inelastic meson-meson scattering. In nonperturbative schemes with chiral-perturbation-theory Lagrangians and in models based on effective meson Lagrangians, inelastic meson-meson scattering leads to the successful identification of resonances in meson-meson reactions, adequate inclusion of final state interactions in particle decays, and so on. For mesons of which each consists of a quark and an antiquark, inelastic meson-meson scattering may be caused by quark-antiquark annihilation, quark-antiquark creation, quark interchange, and quark-antiquark annihilation and creation. In transition amplitudes for meson-meson scattering mesonic quark-antiquark relative-motion wave functions depend on hadronic matter, and transition potentials are given in perturbative quantum chromodynamics. Via transition amplitudes the cross sections for inelastic meson-meson scattering depend on the temperature of hadronic matter. Some prominent temperature dependence of the cross sections has been found. Inelastic meson-meson scattering becomes even more significant in proton-proton collisions and lead-lead collisions at the Large Hadron Collider.

description: The compound CeCuAs2 is found to exhibit negative temperature (T) coefficient of electrical resistivity (rho) under ambient pressure conditions in the entire T-range of investigation (45 mK to 300 K), even in the presence of high magnetic fields. Preliminary tunneling spectroscopic measurements indicate the existence of a psuedo-gap at least at low temperatures, thereby implying that this compound could be classified as a Kondo semi-conductor, though rho(T) interestingly is not found to be of an activated type.

Neutrino helicity asymmetries in leptogenesis

Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: It is pointed out that the heavy singlet neutrinos characteristic of leptogenesis develop asymmetries in the abundances of the two helicity states as a result of the same mechanism that generates asymmetries in the standard lepton sector. Neutrinos and standard leptons interchange asymmetries in collisions with each other. It is shown that an appropriate quantum number, B-L', combining baryon, lepton and neutrino asymmetries, is not violated as fast as the standard B-L. This suppresses the washout effects relevant for the derivation of the final baryon asymmetry. One presents detailed calculations for the period of neutrino thermal production in the framework of the singlet seesaw mechanism.

description: In this work, structural evolution, geometrical and electronic structures of Ta2Sin− and Ta2Sin (n = 3–21) clusters are investigated by joint Crystal structure AnaLYsis by Particle Swarm Optimisation (CALYPSO) global search algorithm and quantum chemical calculations. n = 21 is confirmed as the critical size of forming a Ta2-endohedral silicon cage-like structure for both anionic and neutral Ta2Sin clusters. It is found that the two Ta atoms tend to occupy the high coordination sites and stay close as a whole to bond with the Sin frames, as a result, the global minima of Ta2Sin−/0 (n = 3–21) clusters can be all viewed as a central Ta–Ta bonding axis interacted with the surrounding Si atoms. Ta2Sin−/0 (n = 3−13) clusters are majorly dominated by the bipyramid or prism-based geometries and Ta2Sin−/0 (n = 14−18) clusters are primarily governed by the polyhedral cage-like geometries, whereas Ta2Sin−/0 (n = 19−21) clusters are mainly controlled by the prolate geometries. In particular, Ta2Si3− has a D3h symmetric trigonal bipyramid structure, and Ta2Si6− adopts C2h symmetric chair-shaped structure and Ta2Si12− is a C6v symmetric Ta-face-capped hexagonal antiprism with the other Ta atom at the interior of Si12 cage. The odd-even alternations for the relative stabilities of Ta2Sin−/0 are observed.
Photonic Hybrid State Entanglement Swapping using Cat State Superpositions

description: We propose the use of hybrid entanglement in an entanglement swapping protocol, as means of distributing a Bell state with high fidelity to two parties, Alice and Bob. The hybrid entanglement used in this work is described as a discrete variable (Fock state) and a continuous variable (cat state superposition) entangled state. We model equal and unequal levels of photonic loss between the two propagating continuous variable modes, before detecting these states via a projective vacuum-one-photon measurement, and the other mode via balanced homodyne detection. We investigate homodyne measurement imperfections, and the associated success probability of the measurement schemes chosen in this protocol. We show that our entanglement swapping scheme is resilient to low levels of photonic losses, as well as low levels of averaged unequal losses between the two propagating modes, and show an improvement in this loss resilience over other hybrid entanglement schemes using coherent state superpositions as the propagating modes. Finally, we conclude that our protocol is suitable for potential quantum networking applications which require two nodes to share entanglement separated over a distance of 5-10 km when used with a suitable entanglement purification scheme.

description: The gravitational-wave candidate GW151216 is a proposed binary black hole event from the first observing run of the Advanced LIGO detectors. Not identified as a bona fide signal by the LIGO--Virgo collaboration, there is disagreement as to its authenticity, which is quantified by $p_\text{astro}$, the probability that the event is astrophysical in origin. Previous estimates of $p_\text{astro}$ from different groups range from 0.18 to 0.71, making it unclear whether this event should be included in population analyses, which typically require $p_\text{astro}>0.5$. Whether GW151216 is an astrophysical signal or not has implications for the population properties of stellar-mass black holes and hence the evolution of massive stars. Using the astrophysical odds, a Bayesian method which uses the signal coherence between detectors and a parameterised model of non-astrophysical detector noise, we find that $p_\text{astro}=0.03$, suggesting that GW151216 is unlikely to be a genuine signal. We also analyse GW150914 (the first gravitational-wave detection) and GW151012 (initially considered to be an ambiguous detection) and find $p_\text{astro}$ values of 1 and 0.997 respectively. We argue that the astrophysical odds presented here improve upon traditional methods for distinguishing signals from noise.

description: Addressing the question of whether the Hawking effect depends on degrees of freedom at ultra-high (e.g., Planckian) energies/momenta, we propose three rather general conditions on these degrees of freedom under which the Hawking effect is reproduced to lowest order. As a generalization of Corley's results, we present a rather general model based on non-linear dispersion relations satisfying these conditions together with a derivation of the Hawking effect for that model. However, we also demonstrate counter-examples, which do not appear to be unphysical or artificial, displaying strong deviations from Hawking's result. Therefore, whether real black holes emit Hawking radiation remains an open question and could give non-trivial information about Planckian physics. PACS: 04.70.Dy, 04.62.+v, 04.60.-m, 04.20.Cv.

description: Dysphagia and malnutrition are closely related. Blanař V et al. reported that 39.2% of patients with dysphagia were at risk of malnutrition, and 13.6% of those at risk for malnutrition were reported to have dysphagia. Besides, the prevalence of malnutrition and dysphagia at the same time has been estimated at 3 to 29%. Malnutrition impairs the quality of life of people with dysphagia and prevents them from living a healthy life. Therefore, it is recommended that the nutritional status of all patients with dysphagia should be assessed. However, there are not many reports on nutritional assessment for patients with dysphagia, and there are many unknowns in assessment items. Furthermore, nutritional assessments are not always essential, and nutritional interventions are not still the best timed.Deepen knowledge in this area to reaffirm the importance of nutritional assessment and promote early nutritional intervention. Thereby, patients with dysphagia would be prevented from reducing their quality of life from malnutrition.

description: Fission explosions produce large numbers of antineutrinos. It is occasionally asked whether this distinctive, unshieldable emission could help reveal clandestine nuclear weapon explosions. The practical challenge encountered is that detectors large enough for this application are cost prohibitive, likely on the multi-billion-dollar scale. In this paper, we review several hypothetical use cases for antineutrino detectors as supplements to the seismic, infrasound, hydroacoustic, and airborne radionuclide sensors of the Comprehensive Nuclear-Test-Ban Treaty Organization's International Monitoring System. In each case, if an anti-neutrino detector could be constructed that would compete with existing capabilities, we conclude that the cost would considerably outstrip the value it might add to the existing monitoring network, compared to the significantly lower costs for the same or superior capability.

description: In the conventional BCS description of a superconductor the kinetic energy increases in the superconducting state. We describe the observed decrease in kinetic energy by adopting a simple model of electrons whose elastic scattering rate undergoes a sharp decrease as the temperature is lowered below Tc. This phenomenology has been suggested by other experiments, particularly microwave conductivity. We find that such a decrease accounts for the observed increase; a study of these different phenomena over a wide range of high Tc materials would confirm this correlation.

description: This paper is concerned with the robustness of the sustained oscillations predicted by an epidemic ODE model defined on contact networks. The model incorporates the spread of awareness among individuals and, moreover, a small inflow of imported cases. These cases prevent stochastic extinctions when we simulate the epidemics and, hence, they allow to check whether the average dynamics for the fraction of infected individuals are accurately predicted by the ODE model. Stochastic simulations confirm the existence of sustained oscillations for different types of random networks, with a sharp transition from a non-oscillatory asymptotic regime to a periodic one as the alerting rate of susceptible individuals increases from very small values. This abrupt transition to periodic epidemics of high amplitude is quite accurately predicted by the Hopf-bifurcation curve computed from the ODE model using the alerting rate and the infection transmission rate for aware individuals as tuning parameters.

description: We consider depletion effects of a pear-shaped colloidal particle in a hard-sphere solvent, for two different model realisations of the pear-shaped colloidal particle. The two models are the pear hard Gaussian overlap (PHGO) particles and the hard pears of revolution (HPR). The motivation for this study is to provide a microscopic understanding for the substantially different mesoscopic self-assembly properties of these pear-shaped colloids, in dense suspensions, that have been reported in the first part of this series. This is done by determining the differing depletion attraction via MC simulations of PHGO and HPR particles in a pool of a hard spherical solvent and comparing them with excluded volume calculations of numerically obtained ideal configurations on the microscopic level. While the HPR model behaves as predicted by the analysis of excluded volumes, the PHGO model showcases a preference for splay between neighbouring particles, which can be attributed to the special non-additive characteristics of the PHGO contact function. Lastly, we propose a potentially experimentally realisable pear-shaped particle model, the non-additive hard pear of revolution (NAHPR) model, which is based on the HPR model but also features non-additive traits similar to those of PHGO particles to mimic their depletion behaviour.

description: In this paper, we examine the possible influence of extrinsic factors on the electrical and magnetotransport of La(0.67)Ca(0.33)Mn(1-x)Ru(x)O(3) (x < 0.10). These results not only exclude the extrinsic factors, but establishes the fact that the metal transitions both exhibiting MR is intrinsic to Ru substituted La(0.67)Ca(0.33)MnO(3) and the system. These results substantiate our hypothesis that Ru substituted system undergoes a magnetic phase separation involving the co-existence of two ferromagnetic-metallic phases in its ground state.

description: We analyse luminosity-weighted ages and metallicity (Z) of galaxies in a continuous range of environments, i.e. clusters, filaments and voids prevalent in the Coma supercluster ($\sim 100 h^{-1}$ Mpc). Specifically, we employ two absorption line indices, H$β$ and $\langle\rm{Fe}\rangle$ as tracers of age and metallicity of galaxies. We find that the stellar-phase metallicity of galaxies declines with increasing age as a function of stellar mass ($M^*$) as well as environment. On the filaments, metallicity of galaxies varies as a function of their distance from the spine of the filament, such that galaxies closer to the centre of the filaments have lower metallicity relative to their counterparts 1 Mpc away from it. The mean age of intermediate mass galaxies ($10^{10} < M^*/M_{\odot} < 10^{10.5}$) galaxies is statistically significantly different in different environments such that, the galaxies in clusters are older than the filament galaxies by 1-1.5 Gyr, while their counterparts in the voids are younger than filament galaxies by $\sim 1$ Gyr. The massive galaxies ($M^*/M_{\odot} > 10^{10.5}$), on the other hand show no such difference for the galaxies in clusters and filaments, but their counterparts in voids are found to be younger by $\sim 0.5$ Gyr. At fixed age however, Z of galaxies is independent of their $M^*$ in all environments, except the most massive ($M^*/M_{\odot} \gtrsim 10^{10.7}$), oldest galaxies ($\gtrsim 9$ Gyr) which show a sharp decline in their Z with $M^*$. Our results support a scenario where galaxies in the nearby Universe have grown by accreting smaller galaxies or primordial gas from the large-scale cosmic web.

description: We present a consistent multimode theory that describes the coupling of single photons generated by collinear Type-I parametric down-conversion into single-mode optical fibers. We have calculated an analytic expression for the fiber diameter which maximizes the pair photon count rate. For a given focal length and wavelength, a lower limit of the fiber diameter for satisfactory coupling is obtained.

description: Low energy antideuterons suffer a very low secondary and tertiary astrophysical background, while they can be abundantly synthesized in dark matter pair annihilations, therefore providing a privileged indirect dark matter detection technique. The recent publication of the first upper limit on the low energy antideuteron flux by the BESS collaboration, a new evaluation of the standard astrophysical background, and remarkable progresses in the development of a dedicated experiment, GAPS, motivate a new and accurate analysis of the antideuteron flux expected in particle dark matter models. To this extent, we consider here supersymmetric, universal extra-dimensions (UED) Kaluza-Klein and warped extra-dimensional dark matter models, and assess both the prospects for antideuteron detection as well as the various related sources of uncertainties. The GAPS experiment, even in a preliminary balloon-borne setup, will explore many supersymmetric configurations, and, eventually, in its final space-borne configuration, will be sensitive to primary antideuterons over the whole cosmologically allowed UED parameter space, providing a search technique which is highly complementary with other direct and indirect dark matter detection experiments.

description: A damping-like spin orbit torque (SOT) is a prerequisite for ultralow power spin logic devices. Here, we report on the damping-like SOT in just one monolayer of the conducting transition metal dichalcogenide (TMD) TaS$_2$ interfaced with a NiFe (Py) ferromagnetic layer. The charge-spin conversion efficiency is found to be 0.25$\pm$0.03 and the spin Hall conductivity (2.63 $\times$ 10$^5$ $\frac{\hbar}{2e}$ $Ω^{-1}$ m$^{-1}$) is found to be superior to values reported for other TMDs. The origin of this large damping-like SOT can be found in the interfacial properties of the TaS$_2$/Py heterostructure, and the experimental findings are complemented by the results from density functional theory calculations. The dominance of damping-like torque demonstrated in our study provides a promising path for designing next generation conducting TMD based low-powered quantum memory devices.

title: Improving local corrections for the radar vertical reflectivity profile using the linear depolarisation ratio
Creators: name: Sandford, Caroline Georgina
Publisher: name: University of Reading
Year: 2019

description: A major source of errors in radar-derived quantitative precipitation estimates (QPEs) is the vertical reflectivity profile (VPR). A feature of particular importance is the radar “bright band”: a reflectivity enhancement due to the melting of large snowflakes that occurs in the majority of high latitude rainfall, and which if misrepresented can cause order of magnitude errors in surface QPEs. Recent upgrades of several national weather radar networks to dual polarisation provide opportunities to refine the identification of bright band in operational radar measurements, and to improve subsequent determination and corrections for VPR. This thesis applies information from the linear depolarisation ratio (LDR) to improve classification of VPRs at the pixel scale. Using a unique dataset of high resolution vertical profiles, values of LDR in the melting layer are shown to provide a seven-fold increase in probability of detection of non-bright band reflectivity profiles over the current UK operational criterion. In the context of the Met Office local VPR correction scheme, an LDR-based classification step alone is shown to produce improvements in bias and RMSE of more than 1 mm h−1 for high rain rates in non-bright band conditions. The high resolution vertical profile dataset is then further used to improve the parameterisation of VPR shapes for correction at the local scale. Using a simulation method adapted from previous literature, three possible non-bright band VPR shapes are defined and their performance objectively compared to a control (no correction) profile. The most skilful profile is applied to a high intensity non-bright band case study in combination with LDR-based VPR classification, yielding further improvements to QPE bias and RMSE. Improvements to the stratiform profile are also investigated. The conclusions of this thesis indirectly support the use of local over global VPR corrections to maximise the accuracy of radar QPEs at the sub-kilometre scale.

description: Cette étude a été menée afin d’évaluer la diversité floristique de la florule à Hydrocharis chevalieri  dans le groupement Ambun Intshwem en territoire d’Idiofa où cette espèce est consommée par la population locale. Les données ont été obtenues par les enquêtes de terrain et par les inventaires floristiques dans la communauté végétale. En effet, 136 personnes ont répondu aux questions sur les espèces étudiées. Par ailleurs, 27 placettes ont fait l’objet de récolte des espèces végétales dans les 9 villages échantillon. Ainsi, 92 espèces végétales appartenant à 45 familles botaniques ont été recensées. L’espèce Hydrocharis chevalieri bien que présente par ci par là est devenue de plus en plus rare, tend vers son extinction et ne répond plus aux besoins de la population locale. Cette dégradation est due à la technique de récolte appliquée par la population ainsi qu’aux pressions anthropiques exercées sur le milieu par les activités de pisciculture et d’agriculture pratiquées sur ses habitats. Il faut donc pour conserver cette espèce dans le milieu, procéder par la cueille des feuilles et les tiges,  au lieu d’extirper la plante de l’eau. Par ailleurs, dans le but de pérenniser  son utilisation, des sites protégés à Hydrocharis chevalieri doivent être aménagés dans la région. Une association de l’élevage des poissons et la culture de Hydrocharis chevalieri dans les exploitations piscicoles s’inscrit parmi les pratiques concrètes de gestion durable cette espèce dans la région.
