motivated by recent experiments on α-RuCl3, we investigate a possible quantum.s.in liquid ground state of the honeycomb-lattice spin model with bond-dependent interactions. We consider the K - Γ model, where K and Γ represent the Kitaev and symmetric-anisotropic interactions between spin-1/2 moments on the honeycomb lattice. Using the infinite density matrix renormalization group (iDmRG), we provide compelling evidence for the existence of quantum.s.in liquid phases in an extended region of the phase diagram. In particular, we use transfer matrix spectra to show the evolution of two-particle excitations with well-defined two-dimensional dispersion, which is a strong signature of quantum.s.in liquid. These results are compared with predictions from majorana mean-field theory and used to infer the quasiparticle excitation spectra. Further, we compute the dynamical structure factor using finite size cluster computations and show that the results resemble the scattering continuum.s.en in neutron scattering experiments on α-RuCl3. We discuss these results in light of recent and future experiments. Copyright © 2017, The Authors. All rights reserved.

Despite substantial declines since 2000, lower respiratory infections (LRIs), diarrhoeal diseases, and malaria remain among the leading causes of nonfatal and fatal disease burden for children under 5 years of age (under 5), primarily in sub-saharan Africa (ssA). The spatial burden of each of these diseases has been estimated subnationally across ssA, yet no prior analyses have examined the pattern of their combined burden. Here we synthesise subnational estimates of the burden of LRIs, diarrhoea, and malaria in children under-5 from 2000 to 2017 for 43 sub-saharan countries. some units faced a relatively equal burden from each of the three diseases, while others had one or two dominant sources of unit-level burden, with no consistent pattern geographically across the entire subcontinent. Using a subnational counterfactual analysis, we show that nearly 300 million DALYs could have been averted since 2000 by raising all units to their national average. Our findings are directly relevant for decision-makers in determining which and targeting where the m.s. appropriate interventions are for increasing child survival. © 2022, The Author(s).

specialized computational chem.s.ry packages have permanently reshaped the landscape of chemical and materials science by providing tools to support and guide experimental efforts and for the prediction of atom.s.ic and electronic properties. In this regard, electronic structure packages have played a special role by using first-principle-driven methodologies to model complex chemical and materials processes. Over the last few decades, the rapid development of computing technologies and the tremendous increase in computational power have offered a unique chance to study complex transformations using sophisticated and predictive many-body techniques that describe correlated behavior of electrons in molecular and condensed phase systems at different levels of theory. In enabling these simulations, novel parallel algorithms have been able to take advantage of computational resources to address the polynomial scaling of electronic structure methods. In this paper, we briefly review the NWChem computational chem.s.ry suite, including its history, design principles, parallel tools, current capabilities, outreach and outlook.

The General Antiparticle spectrometer (GAPs) is designed to carry out indirect dark matter search by measuring low-energy cosmic-ray antiparticles. Below a few GeVs the flux of antiparticles produced by cosmic-ray collisions with the interstellar medium is expected to be very low and several well-motivated beyond-standard models predict a sizable contribution to the antideuteron flux. GAPs is planned to fly on a long-duration balloon over Antarctica in the austral summer of 2020. The primary detector is a ∼1m3 central volume containing planes of si(Li) detectors. This volume is surrounded by a time-of-flight system to both trigger the si(Li) detector and reconstruct the particle tracks. The detection principle of the experiment relies on the identification of the antiparticle annihilation pattern. Low energy antiparticles slow down in the apparatus and they are captured in the medium to form exotic excited atoms, which de-excite by emitting characteristic X-rays. Afterwards they undergo nuclear annihilation, resulting in a star of pions and protons. The simultaneous measurement of the stopping depth and the dE/dx loss of the primary antiparticle, of the X-ray energies and of the star particle-multiplicity provides very high rejection power, that is critical in rare-event search. GAPs will be able to perform a precise measurement of the cosmic antiproton flux below 250 meV, as well as a sensitive search for antideuterons. Copyright © 2018, The Authors. All rights reserved.

Designing the jet ejector optimally is a challenging task and has a great impact on industrial applications. Three different sets of nozzles (namely, 1, 3, and 5) inside the jet ejector are compared in this study by using numerical simulations. more precisely, dynamics of bubble coalescence and breakup in the multinozzle jet ejectors are studied by means of Computational Fluid Dynamics (CFD). The population balance approach is used for the gas phase such that different bubble size groups are included in CFD and the number densities of each of them are predicted in CFD simulations. Here, commercial CFD software ANsYs Fluent 14.0 is used. The realizable k - Ε turbulence model is used in CFD code in three-dimensional computational domains. It is clear that Reynolds-Averaged Navier-stokes (RANs) models have their limitations, but on the other hand, turbulence modeling is not the key issue in this study and we can assume that the RANs models can predict turbulence of the carrying phase accurately enough. In order to validate our numerical predictions, results of one, three, and five nozzles are compared to laboratory experiments data for Cl2-NaOH system. Predicted gas volume fractions, bubble size distributions, and resulting number densities of the different bubble size groups as well as the interfacial area concentrations are in good agreement with experimental results. © 2016 Dhanesh Patel et al.

We present the 850 µm polarization observations toward the IC5146 filamentary cloud taken using the submillimetre Common-User Bolometer Array 2 (sCUBA-2) and its associated polarimeter (POL-2), mounted on the Jam.s.Clerk maxwell Telescope (JCmT), as part of the B-fields In sTar forming Regions Observations (BIsTRO). This work is aimed at revealing the magnetic field morphology within a core-scale (. 1.0 pc) hub-filament structure (HFs) located at the end of a parsec-scale filament. To investigate whether or not the observed polarization traces the magnetic field in the HFs, we analyze the dependence between the observed polarization fraction and total intensity using a Bayesian approach with the polarization fraction described by the Rice likelihood function, which can correctly describe the probability density function (PDF) of the observed polarization fraction for low signal-to-noise ratio (sNR) data. We find a power-law dependence between the polarization fraction and total intensity with an index of 0.56 in AV ∼ 20–300 mag regions, suggesting that the dust grains in these dense regions can still be aligned with magnetic fields in the IC5146 regions. Our polarization maps reveal a curved magnetic field, possibly dragged by the contraction along the parsec-scale filament. We further obtain a magnetic field strength of 0.5±0.2 mG toward the central hub using the Davis-Chandrasekhar-Fermi method, corresponding to a m.s.-to-flux criticality of ∼ 1.3±0.4 and an Alfvénic mach number of Copyright © 2018, The Authors.

The present review article contains various applications of Thermoluminescence. The phenomena of thermoluminescence (TL) or thermally stimulated luminescence (TsL) and optically stimulated luminescence (OsL) are widely used for measurement of radiation doses from ionizing radiations, viz. x-rays,rays and ß particles. The applications of TL are initiated in the field of Geology followed by Archaeology, personal dosimetry, material characterization and many more to name. The TL technique has been found to be useful in dating specimens of geologically recent origin where all other conventional methods fail. It has been found to be highly successful in dating ancient pottery samples. The TL/OsL dating is done from a quartz grain, which is collected from pottery or brick, by reading the TL-output. The main basis in the Thermoluminescence Dosimetry (TLD) is that TL output is directly proportional to the radiation dose received by the phosphor and hence provides the means of estimating the dose from unknown irradiations. The TL dosimeters are being used in personnel, environmental and medical dosimetry. During the last two decades, OsL based dosimeters have also been used for various applications. Natural and induced TL signals can be used to explore mineral, oil and natural gas. The present review presents TL theory, TL of minerals, salt, cement, salt crystals from pickles, and low temperature thermoluminescence (LLTL) of few agricultural products.

Thermoluminescence reader is an important tool and a requisite for a researcher to study and characterize Thermoluminescence (TL) materials in different forms. Requirement for a versatile PC Controlled TL Reader has been felt for quite some time globally. Nucleonix systems, Hyderabad, India, have developed a PC Controlled TL Reader by integrating complete electronics hardware circuits (comprising of Power Electronics, Low/High voltage supplies, Temperature Controller, micro Controller based data acquisition circuits having serial counter, ADC, DAC, EEPROm, PmT, PmT housing, sample heating system, drawer assembly, etc.) in a single enclosure. The system also integrated with software to calculate the activation energy (E), frequency factor (s) and order of kinetics '1' for the prominent glow peaks using different equations. This Integral TL Reader unit gets connected to the Personal Computer system through serial port Rs232C/UsB port. The user interface to the system is through front-end VB software defined Graphics User Interface (GUI). The system also contains some of the software features like glow curve acquisition, analysis, filing, printing, plotting, overlapping, maker data reporting, etc. Additionally, system facilitates single/two/three plateau heating with variable heating rates. The primary objective of this development is to bring out versatile TL instrumentation system and also to make it affordable to many of the researchers in the Universities and other areas, including Radio-therapist, medical Physicists in Cancer Hospitals.
