description: We present first principles calculations of the nontrivial surface states and their spin-textures in the topological crystalline insulator SnTe. The surface state dispersion on the [001] surface exhibits four Dirac-cones centered along the intersection of the mirror plane and the surface plane. We propose a simple model of two interacting coaxial Dirac cones to describe both the surface state dispersion and the associated spin-texture. While the out-of-the-plane spin polarization is zero due to the crystalline and time-reversal symmetries, the in-plane spin texture shows helicity with some distortion due to the interaction of the two coaxial Dirac cones, indicating a nontrivial mirror Chern number of -2, distinct from the value of -1 in $Z_{2}$ topological insulator such as Bi/Sb alloys or Bi$_2$Se$_3$. The surface state dispersion and its spin-texture would provide an experimentally accessible way to determine the nontrivial mirror Chern number.

description: Planck cold clumps are among the most promising objects to investigate the initial conditions of the evolution of molecular clouds. In this work, by combing the dust emission data from the survey of Planck satellite with the molecular data of $^{12}$CO/$^{13}$CO (1-0) lines from observations with the Purple Mountain Observatory (PMO) 13.7 m telescope, we investigate the CO abundance, CO depletion and CO-to-H$_{2}$ conversion factor of 674 clumps in the early cold cores (ECC) sample. The median and mean values of the CO abundance are 0.89$\times10^{-4}$ and 1.28$\times10^{-4}$, respectively. The mean and median of CO depletion factor are 1.7 and 0.9, respectively. The median value of $X_{CO-to-H_{2}}$ for the whole sample is $2.8\times10^{20}$ cm$^{-2}$K$^{-1}$km$^{-1}$ s. The CO abundance, CO depletion factor and CO-to-H$_{2}$ conversion factor are strongly (anti-)correlated to other physical parameters (e.g. dust temperature, dust emissivity spectral index, column density, volume density and luminosity-to-mass ratio). To conclude, the gaseous CO abundance can be used as an evolutionary tracer for molecular clouds.

description: The scattering theory approach makes it possible to carry out exact calculations of Casimir energies in any geometry for which the scattering T-matrix and a partial wave expansion of the free Green's function are available. We implement this program for the case of a perfectly conducting elliptic cylinder, thereby completing the set of geometries where electromagnetic scattering is separable. Particular emphasis is placed on the case of zero radius, where the elliptic cylinder reduces to a strip.

description: We report measurements of the spatial dependence of the electron energy distribution in carbon nanotubes, from which electron interactions are determined. Using nonequilibrium tunneling spectroscopy with multiple superconducting probes, we characterize electron transport as ballistic or diffusive, and interactions as elastic or inelastic. We find that transport in nanotubes is generally diffusive, caused by elastic scattering from a few defects. However, local inelastic scattering can be tuned `on' or `off' with a gate voltage.

description: Recently measured fusion cross-sections for the neutron-rich system 20O+12C are compared to dynamic, microscopic calculations using time-dependent density functional theory. The calculations are carried out on a three-dimensional lattice and performed both with and without a constraint on the density. The method has no adjustable parameters, and its only input is the Skyrme effective NN interaction. While the microscopic DC-TDHF calculations lie closer to the experimental data than standard fusion systematics they underpredict the experimental data significantly.

description: Methane hydrates are encountered in a plethora of industrial and geological or environmental applications. In the current study, we present a novel methodology which is based on molecular dynamics simulations for the calculation of the enthalpy of enclathration of sI methane hydrates. Simulations are performed along the three-phase (Hydrate – Liquid water – Vapour; H–Lw–V) equilibrium line in the temperature range 274–310 K. The methodology takes into account the two different types of cages that are present in the sI methane hydrate and provides results for the enthalpy of enclathration for both types of cages, while it avoids performing calculations with the metastable, completely empty hydrate lattice. The formulation proposed is general and can be also applied to sII hydrates, while it can be modified/extended appropriately for use in the case of sH hydrates. Comparison is provided with available data from the literature and good agreement is observed.

description: Purpose – The purpose of this paper is to investigate and identify the status of Web Content Accessibility Guidelines (WCAG) conformance levels (A, AA, AAA) and accessibility status in terms of Severity (Error, Warning and Review) and Responsibility (Editor, Webmaster and Developer) of Indian Institutes of Technology (IIT) Library websites based on Site improve Software-as-a-Service (SaaS) platform.
 Design/methodology/approach – The library websites of IITs were tested using Site improve web-tool to gather details pertaining to W3C’s WCAG 2.1 standards. The data thus obtained were then visualized using spreadsheet software for greater insight. A partial correlation test was also done to assess the relationship between the three conformance levels.
 Findings – The study could identify significant accessibility-related limitations of the IIT library websites concerning the three WCAG 2.1 conformance levels A (max IIT Bombay), AA (max IIT Dhanbad (ISM)) and AAA (max IIT Gandhinagar and IIT Varanasi (BHU)), Severity and Responsibility. A positive linear relationship exists amongst these conformance levels. The mean value of conformance levels were found to be 18.3 (A), 2.2 (AA) and 3.1 (AAA); Severity scores were found to be 14.4 (Error), 3.9 (Warning) and 5.2 (Review); and Responsibility scores were found to be 6 (Editor), 9.3 (Webmaster) and 8.3 (Developer), respectively.
 Practical implications – The study highlights the comparative picture of accessibility issues and conformance levels of the IITs’ library website homepage with the help of results derived/based on Site improve Accessibility Checker. The findings of the study reveal that though the library website of IITs’ in India possess a well-designed and easily navigable website homepage as far as their accessibility for VIPs is concerned, there are several issues that are still to be resolved.
 Social implications – World Intellectual Property Organization’s (WIPO) Marrakesh VIP Treaty (MVT) and the W3C’s WCAG cater to the requirements and rights of the persons with vision-related disability of accessing information and knowledge building a steeper and deeper knowledge divide. Identifying and rectifying the shortcomings in the library websites will bridge the accessibility-divide and make the society more inclusive.
 Originality/value – No previous study could be identified evaluating the accessibility issues of the library website of Indian IITs focused on vision-disabled persons using Site improve. The methodology and approach of this paper have value in terms of reusability and reproducibility facilitating future studies.

description: The influence of dispersive long-range interactions on properties of vapour–liquid equilibria and interfaces of six binary Lennard-Jones (LJ) mixtures was studied by molecular dynamics (MD) simulations and density gradient theory (DGT). The mixtures were investigated at a constant temperature T, at which the low-boiling component, which is the same in all mixtures, is subcritical. Two different high-boiling components were considered: one is subcritical, the other is supercritical at T. Furthermore, the unlike dispersive interaction was varied such that mixtures with three different types of phase behaviour were obtained: ideal, low-boiling azeotrope, and high-boiling azeotrope. In a first series of simulations, the full LJ potential was used to describe these mixtures. To assess the influence of the long-range interactions, these results were compared with simulations carried out with the LJ truncated and shifted (LJTS) potential applying the corresponding states principle. The dispersive long-range interactions have a significant influence on the surface tension and the interfacial thickness of the studied mixtures, whereas the relative adsorption and the enrichment are hardly affected. Furthermore, the influence of the long-range interactions on Henry's law constants and the phase envelopes of the vapour–liquid equilibrium was investigated. The long-range interactions have practically no influence on the composition dependency of the investigated mixture properties.

description: Fluid properties change when the fluid is adsorbed at a wall. The effect of the adsorption on the fluid properties was studied here by molecular simulation. There is much previous work in this field on fluids in nanochannels that are so small that the adsorbed layers on both walls interfere. In this work, the channel width was so large that the adsorbed layers did not interfere, such that information on the adsorbed layer on single walls was obtained and average values of thermodynamic properties of the fluid in that layer were determined. The studied fluid properties are: pressure p, density ρ, internal energy u, enthalpy h, isobaric heat capacity cp, thermal expansion coefficient αp, thermal conductivity λ, shear viscosity η and self-diffusion coefficient D. For the study, non-equilibrium molecular dynamics simulations were carried out. The fluid and the solid were modelled with the Lennard–Jones potential truncated and shifted at rc∗=2.5σ. The overall density of the fluid was ρ¯=0.8. The overall temperature and the solid–fluid interaction were varied. The corresponding bulk states are liquid or supercritical. The results for the fluid properties in the adsorbed layer were compared to the corresponding bulk values and the deviations are generally below 15%.

description: Motivated by the excess in the diphoton production rate of the Higgs boson at the Large Hadron Collider (LHC), we investigate the possibility that one of the CP-even Higgs bosons of the extra U(1) extended minimal supersymmetric standard model can give a consistent result. We scan the parameter space for a standard-model-like Higgs boson such that the mass is in the range of 124-127 GeV and the production rate σxB of the WW*, ZZ* modes are consistent with the standard model (SM) values while that of γγis enhanced relative to the SM value. We find that the SM-like Higgs boson is mostly the lightest CP-even Higgs boson and it has a strong mixing with the second lightest one, which is largely singlet-like. The implications on Zγproduction rate and properties of the other Higgs bosons are also studied.

A measurement-induced optical Kerr interaction

description: We present a method for implementing a weak optical Kerr interaction (single-mode Kerr Hamiltonian) in a measurement-based fashion using the common set of universal elementary interactions for continuous-variable quantum computation. Our scheme is a conceptually distinct alternative to the use of naturally occurring, weak Kerr nonlinearities or specially designed nonlinear media. Instead, we propose to exploit suitable offline prepared quartic ancilla states together with beam splitters, squeezers, and homodyne detectors. For perfect ancilla states and ideal operations, our decompositions for obtaining the measurement-based Kerr Hamiltonian lead to a realization with near-unit fidelity. Nonetheless, even by using only approximate ancilla states in the form of superposition states of up to four photons, high fidelities are still attainable. Our scheme requires four elementary operations and its deterministic implementation corresponds to about ten ancilla- based gate teleportations. We test our measurement-based Kerr interaction against an ideal Kerr Hamiltonian by applying them both to weak coherent states and single-photon superposition states.

description: Amplitudes for the reaction $π^-p\to ΛK^0$ are reconstructed from data on the differential cross section $dσ/dΩ$, the recoil polarization $P$, and on the spin rotation parameter $β$. At low energies, no data on $β$ exist, resulting in ambiguities. An approximation using $S$ and $P$ waves leads only to a fair description of the data on $dσ/dΩ$ and $P$; in this case, there are two sets of amplitudes. Including $D$ waves, the data on $dσ/dΩ$ and $P$ are well reproduced by the fit but now, there are several distinct solutions which describe the data with identical precision. In the range where the spin rotation parameter $β$ was measured, a full and unambiguous reconstruction of the partial wave amplitudes is possible. The energy-independent amplitudes are compared to the energy dependent amplitudes which resulted from a coupled channel fit (BnGa2011-02) to a large data set including both pion and photo-induced reactions. Significant deviations are observed. Consistency between energy dependent and energy independent solutions by choosing the energy independent solution which is closest to the energy dependent solution. In a second step, the {\it known} energy dependent solution for low (or high) partial waves is imposed and only the high (or low) partial waves are fitted leading to smaller uncertainties.

description: A detailed comparison is made of results from the Lunar Prospector Neutron Spectrometer (LPNS) and the Lunar Exploration Neutron Detector Collimated Sensors for EpiThermal Neutrons (LEND CSETN). Using the autocorrelation function and power spectrum of the polar count rate maps produced by these experiments, it is shown that the LEND CSETN has a footprint that is at least as big as would be expected for an omni-directional detector at an orbital altitude of 50 km. The collimated flux into the field of view of the collimator is negligible. Arguments put forward asserting otherwise are considered and found wanting for various reasons. The maps of lunar polar hydrogen with the highest contrast, i.e. spatial resolution, are those resulting from pixon image reconstructions of the LPNS data. These typically provide weight percentages of water equivalent hydrogen that are accurate to 30% within the polar craters.

description: In a Peccei-Quinn extension of supergravity the h --> γγdetection rate can be significantly enhanced due to the reduction of the total Higgs decay width. To assess the viability of various Peccei-Quinn extensions of minimal supergravity we perform a Bayesian analysis on three such scenarios. The main constraints on these models come from the currently observed Higgs boson like state by the Large Hadron Collider and from the WMAP observation of dark matter abundance. Our comparative study reveals that under these constraints the PQ violating scenarios with axino dark matter are clearly preferred over the minimal supegravity model with the lightest neutralino as a dark matter candidate.

description: We estimate the parameters of the Kennicutt-Schmidt (KS) relationship, linking the star formation rate (Sigma_SFR) to the molecular gas surface density (Sigma_mol), in the STING sample of nearby disk galaxies using a hierarchical Bayesian method. This method rigorously treats measurement uncertainties, and provides accurate parameter estimates for both individual galaxies and the entire population. Assuming standard conversion factors to estimate Sigma_SFR and Sigma_mol from the observations, we find that the KS parameters vary between galaxies, indicating that no universal relationship holds for all galaxies. The KS slope of the whole population is 0.76, with the 2sigma range extending from 0.58 to 0.94. These results imply that the molecular gas depletion time is not constant, but varies from galaxy to galaxy, and increases with the molecular gas surface density. Therefore, other galactic properties besides just Sigma_mol affect Sigma_SFR, such as the gas fraction or stellar mass. The non-universality of the KS relationship indicates that a comprehensive theory of star formation must take into account additional physical processes that may vary from galaxy to galaxy.

Search for charged Higgs bosons through the violation of lepton universality in ttbar events using pp collision data at sqrt(s) = 7 TeV with the ATLAS experiment

description: In several extensions of the Standard Model, the top quark can decay into a bottom quark and a light charged Higgs boson H+, t to bH+, in addition to the Standard Model decay t to bW. Since W bosons decay to the three lepton generations equally, while H+ may predominantly decay into tau+nu, charged Higgs bosons can be searched for using the violation of lepton universality in top quark decays. The analysis in this paper is based on 4.6/fb of proton-proton collision data at sqrt(s) = 7 TeV collected by the ATLAS experiment at the Large Hadron Collider. Signatures containing leptons (e or mu) and/or a hadronically decaying tau (tau_had) are used. Event yield ratios between e+tau_had and e+mu, as well as between mu+tau_had and mu+e, final states are measured in the data and compared to predictions from simulations. This ratio-based method reduces the impact of systematic uncertainties in the analysis. No significant deviation from the Standard Model predictions is observed. With the assumption that the branching fraction B(H+ to tau+nu) is 100%, upper limits in the range 3.2%-4.4% can be placed on the branching fraction B(t to bH+) for charged Higgs boson masses m(H+) in the range 90-140 GeV. After combination with results from a search for charged Higgs bosons in ttbar decays using the tau_had+jets final state, upper limits on B(t to bH+) can be set in the range 0.8%-3.4%, for m(H+) in the range 90-160 GeV.

We measure the angular and spectral distributions of parametric fluorescence in a beta-barium borate crystal pumped by a 405-nm diode laser employing angle-resolved imaging spectroscopy. The experimental angle-resolved spectra and the generation efficiency of parametric down conversion are compared with a plane-wave theoretical analysis. The parametric fluorescence is used as a broadband light source for the calibration of the instrument spectral response function in the wavelength range from 450 to 1000 nm.

However, the accuracy of using the BIC on brain injury risk estimation across different types of head impacts has not been evaluated. Physiologically, brain strain is often considered the key parameter of brain injury. To evaluate the BIC's risk estimation accuracy across five datasets comprising different head impact types, linear regression was used to model 95% maximum principal strain, 95% maximum principal strain at the corpus callosum, and cumulative strain damage (15%) on each of 18 BIC respectively. The results show a significant difference in the relationship between BIC and brain strain across datasets, indicating the same BIC value may suggest different brain strain in different head impact types. The accuracy of brain strain regression is generally decreasing if the BIC regression models are fit on a dataset with a different type of head impact rather than on the dataset with the same type. Given this finding, this study raises concerns for applying BIC to estimate the brain injury risks for head impacts different from the head impacts on which the BIC was developed.

description: Systems composed of soft matter (e.g. liquids, polymers, foams, gels, colloids, and most biological materials) are ubiquitous in science and engineering, but molecular simulations of such systems pose particular computational challenges, requiring time and/or ensemble-averaged data to be collected over long simulation trajectories for property evaluation. Performing a molecular simulation of a soft matter system involves multiple steps, which have traditionally been performed by researchers in a ‘bespoke’ fashion, resulting in many published soft matter simulations not being reproducible based on the information provided in the publications. To address the issue of reproducibility and to provide tools for computational screening, we have been developing the open-source Molecular Simulation and Design Framework (MoSDeF) software suite. In this paper, we propose a set of principles to create Transparent, Reproducible, Usable by others, and Extensible (TRUE) molecular simulations. MoSDeF facilitates the publication and dissemination of TRUE simulations by automating many of the critical steps in molecular simulation, thus enhancing their reproducibilitya. We provide several examples of TRUE molecular simulations: All of the steps involved in creating, running and extracting properties from the simulations are distributed on open-source platforms (within MoSDeF and on GitHub), thus meeting the definition of TRUE simulations.

description: We propose a scheme based on the coherent excitation of a two-level system in a cavity to generate an ultrabright CW and focused source of quantum light that comes in groups (bundles) of $N$ photons, for an integer $N$ tunable with the frequency of the exciting laser. We define a new quantity, the \emph{purity} of $N$-photon emission, to describe the percentage of photons emitted in bundles, thus bypassing the limitations of Glauber correlation functions. We focus on the case $1\le N\le3$ and show that close to 100% of two-photon emission and 90% of three-photon emission is within reach of state of the art cavity QED samples. The statistics of the bundles emission shows that various regimes---from $N$-photon lasing to $N$-photon guns---can be realized. This is evidenced through generalized correlation functions that extend the standard definitions to the multi-photon level.

description: The influence of dietary factors (including endophyte exposure, phytogenic supplementation, and controlled feeding) on relationships between exit velocity (EV), growth performance in grazing and finishing cattle, and carcass characteristics were explored. Two grazing studies were conducted evaluating EV effects on cattle grazing both toxic and nontoxic endophyte-infected tall fescue. Cattle were followed through two subsequent finishing studies and an additional beef cattle finishing beef cattle study was also conducted. Results from these studies agree with many literature reports indicating that EV measures relate to growth performance and associated carcass traits in beef cattle being fed high energy diets in confinement, but also indicated that a high degree of acclimation to handling prior to EV determination can erode the value of EV as a predictor of finishing performance. Relationships between EV and ADG under grazing conditions were weaker and less predictable. Prior handling and acclimation to facilities may influence ability to accurately measure relationships between EV and growth performance. Large difference in grazing ADG, induced by differences in exposure to endophytic alkaloids, did not alter the relationship between EV and ADG during finishing. Grazing toxic vs. non-toxic tall fescue showed potential to influence the response to dietary supplementation with a commercial phytogenic additive. Additionally, determining proper components, mode of action, proper dosage, and all potential effects of phytogenic supplementation on beef cattle is needed before consideration as either complements or replacements to antibiotics. Finally, utilizing controlled feeding may be beneficial for testing particular hypotheses but economic benefit is questionable when considering loss in overall hot carcass weight.

description: Il presente contributo è il primo report sulla ricerca biennale 2020-2021 che, a partire da marzo 2020, gli autori stanno conducendo utilizzando modalità operative esclusivamente online e coinvolgendo alcune scuole dell’infanzia e primarie del Lazio e della Toscana. Obiettivo della ricerca è quello di individuare uno sfondo integratore che dia conto delle radici culturali dalle quali nasce e trae alimento l’attuale clima normativo-culturale-educativo relativo alle pratiche di inclusione in Italia. Per condurre la ricerca la metodologia Grounded Theory a indirizzo costruttivista è stata pensata come scelta migliore. Attualmente i ricercatori hanno individuato circa dieci categorie interpretative e numerose proprietà a esse relative, e si accingono all’elaborazione dei dati prevista per il secondo livello di analisi, quello della codifica focalizzata.

Dense Nanosuspension Drop Impact onto a Hard Spherical Target
Creators: name: Abboud, Mohammad
Publisher: name: Zenodo

description: The design of novel smart and functional nanomaterials often involves the use of highly dense
 nanosuspensions with various rheological properties. Characterizing the rheological behavior of dense
 nanosuspensions is a critical, yet, challenging task due their viscoelastic nature and progressive shear
 thinning. Drop impact on a solid sphere is a phenomenon which can be used to determine the
 rheological behavior of simple Newtonian liquids by observing the spatial and temporal variation of
 the liquid film thickness of the droplet that forms upon impact. Three temporal phases are often
 observed, namely, initial deformation phase, inertia dominated phase, and a viscosity dominated
 phase. In this work, we perform droplet impact experiments of dense capillary nanosuspensions on
 hard spherical targets. The Droplet impact methods is to be modified to account for the variable
 viscosity versus shear rate and for their characteristic viscoelastic behavior. The method is first tested
 with Newtonian liquids to correlate the viscosity to various impact velocities, then variable velocities
 are used to obtain the shear-thinning viscosity profile of the dense nanosuspensions. Force sensors are
 used to measure the force of impact at each velocity. Both the size of the droplet and that of the
 spherical target were varied to include a wide range of droplet-to-target ratios. The impact is observed
 using high-speed imaging from two perpendicular angles and the results are analyzed using a digital
 image processing code. Finally, a theoretical model has been developed to allow the measurements of
 viscoelastic parameters such as the complex modulus profile and yield strength of non-Newtonian
 liquids. The ability to characterize such properties over a wide range of strain rates and using minimal
 sample quantities are important advantages of the technique of this work. The method and gained
 knowledge about the rheological behavior of dense nanosuspensions will be later used to design novel
 functional smart liquid and solid nanomaterials.

description: A data-driven framework is presented for building magneto-elastic machine-learning interatomic potentials (ML-IAPs) for large-scale spin-lattice dynamics simulations. The magneto-elastic ML-IAPs are constructed by coupling a collective atomic spin model with an ML-IAP. Together they represent a potential energy surface from which the mechanical forces on the atoms and the precession dynamics of the atomic spins are computed. Both the atomic spin model and the ML-IAP are parametrized on data from first-principles calculations. We demonstrate the efficacy of our data-driven framework across magneto-structural phase transitions by generating a magneto-elastic ML-IAP for α-iron. The combined potential energy surface yields excellent agreement with first-principles magneto-elastic calculations and quantitative predictions of diverse materials properties including bulk modulus, magnetization, and specific heat across the ferromagnetic-paramagnetic phase transition.

description: In an early-type, massive star binary system, X-ray bright shocks result from the powerful collision of stellar winds driven by radiation pressure on spectral line transitions. We examine the influence of the X-rays from the wind-wind collision shocks on the radiative driving of the stellar winds using steady state models that include a parameterized line force with X-ray ionization dependence. Our primary result is that X-ray radiation from the shocks inhibits wind acceleration and can lead to a lower pre-shock velocity, and a correspondingly lower shocked plasma temperature, yet the intrinsic X-ray luminosity of the shocks, LX remains largely unaltered, with the exception of a modest increase at small binary separations. Due to the feedback loop between the ionizing X-rays from the shocks and the wind-driving, we term this scenario as self regulated shocks. This effect is found to greatly increase the range of binary separations at which a wind-photosphere collision is likely to occur in systems where the momenta of the two winds are significantly different. Furthermore, the excessive levels of X-ray ionization close to the shocks completely suppresses the line force, and we suggest that this may render radiative braking less effective. Comparisons of model results against observations reveals reasonable agreement in terms of log(LX/Lbol). The inclusion of self regulated shocks improves the match for kT values in roughly equal wind momenta systems, but there is a systematic offset for systems with unequal wind momenta (if considered to be a wind-photosphere collision).

description: Il saggio propone una riflessione critica sul ruolo sociale di artiste-i durante la Pandemia Covid 19. L’analisi è pluridimensionale: l’azione sociale di artiste-i, le decisioni politiche, la collocazione economica della cultura. Si tratta di una categoria fortemente colpita dalle misure restrittive che hanno sospeso la loro attività lavorativa da marzo 2020, ma artiste-i  hanno utilizzato tutti i media possibili, per poter continuare ad esistere, e dare forma alle emozioni e alle rappresentazioni valoriali, per rispondere all’angoscia e alla generale insicurezza; con l’intenzione di affermare un senso di comunità e di condivisione, di rispetto per le regole governative sulla prevenzione del contagio (con rari casi di azioni anarchiche),  con l0intenzione politica di riprogettare la socialità post-pandemia.
