description: Under a hypothesis which is slightly stronger than the Riemann Hypothesis for elliptic curve $L$-functions, we show that both the average analytic rank and the average algebraic rank of elliptic curves in families of quadratic twists are exactly $\frac 12$. As a corollary we obtain that under this last hypothesis, the Birch and Swinnerton-Dyer Conjecture holds for almost all curves in our family, and that asymptotically one half of these curves have algebraic rank $0$, and the remaining half $1$. We also prove an analogous result in the family of all elliptic curves. A way to interpret our results is to say that nonreal zeros of elliptic curve $L$-functions in a family have a direct influence on the average rank in this family. Results of Katz-Sarnak and of Young constitute a major ingredient in the proofs.

description: Daksha is an ambitious mission, expected to be the most sensitive high energy time-domain tele- scope. It will detect the highest number of GRBs and other high energy transients than any other mission. In addition to the interesting science with fainter and more distant sources, Daksha will also significantly impact the study of bright transients by measuring rapid spectral and temporal variations. A key feature is Daksha’s ability to measure X-ray polarisation by utilizing multi-pixel events caused by Compton scattering of incoming photons. The large effective area, open CZT de- tectors, and the all-sky coverage make Daksha at least an order of magnitude more sensitive than the current generation satellites measuring GRB polarisation. The spectral and temporal analysis of GRB data allows us to identify models that are consistent with data; however, there are degen- eracies among the various models. Different models give rise to a different degree of polarisation. A statistical analysis of GRBs’ polarisation properties can help us constrain the models. In this work, we will present how Daksha and its capability of polarisation measurement will help us probe the physical processes related to GRBs and put constraints on the existing models related to GRBs.

description: Towards the high galactic latitude sky, the far-infrared (FIR) intensity is tightly correlated to the total hydrogen column density which is made up of atomic (HI) and molecular hydrogen (H$_{2})$. Above a certain column density threshold, atomic hydrogen turns molecular. We analyse gas and dust properties of intermediate-velocity clouds (IVCs) in the lower galactic halo to explore their transition from the atomic to the molecular phase. Driven by observations, we investigate the physical processes that transform a purely atomic IVC into a molecular one. Data from the Effelsberg-Bonn HI-Survey (EBHIS) are correlated to FIR wavebands of the Planck satellite and IRIS. Modified black-body emission spectra are fitted to deduce dust optical depths and grain temperatures. We remove the contribution of atomic hydrogen to the FIR intensity to estimate molecular hydrogen column densities. Two IVCs show different FIR properties, despite their similarity in HI, such as narrow spectral lines and large column densities. One FIR bright IVC is associated with H$_{2}$, confirmed by $^{12}$CO $(1\rightarrow0)$ emission; the other IVC is FIR dim and shows no FIR excess, which indicates the absence of molecular hydrogen. We propose that the FIR dim and bright IVCs probe the transition between the atomic and molecular gas phase. Triggered by dynamical processes, this transition happens during the descent of IVCs onto the galactic disk. The most natural driver is ram pressure exerted onto the cloud by the increasing halo density. Because of the enhanced pressure, the formation timescale of H$_{2}$ is reduced, allowing the formation of large amounts of H$_{2}$ within a few Myr.

description: Soybeans are used as food, feed, oil and fuel. Losses may happen at harvesting, transportation, and mainly during storage. Moisture content (MC %) and temperature (T °C) of the soybean grain mass during storage are the main factors affecting quality, quantity and value of the product by favoring the development of microorganisms and insects. Large grain chillers have been used to maintain soybean quality and reduce insect infestation during storage. To evaluate the effect of MC and temperature on the quality parameters of soybean seeds, samples were stored at 58±2% RH, with five different MCs, at 15 °C (chilling temperature) and 30 °C (average temperature inside silos in Brazil) for 180 days. The following was observed: reduction in the MC at higher temperature; the weight of soybeans was maintained at either temperature when the MC was at about 12%; MC above 14% reduced the weight value independent of storage temperature; at 15°C the weight of 1,000 seeds was maintained during storage; low MC and temperature kept germination and vigor of the seeds at high rates; low MC and temperature reduced electrical conductivity; there was no noticeable influence of the storage temperature, regardless of the MC of the beans, on the free fatty acid content. In general, quality attributes tend to be reduced during storage, being more remarkable at higher temperature and MC of the seeds. In conclusion, the temperature of 15ºC, which simulates grain cooling conditions, favors the maintenance of quality, quantity and value of soybean for long-term storage.

description: We present a fully-differential calculation of the NNLO QCD corrections to the t-channel mechanism for producing single top quarks at the LHC. We work in the structure function approximation, computing QCD corrections to the light- and heavy-quark lines separately and neglecting the dynamical cross-talk between the two. The neglected contribution, which appears at NNLO for the first time, is color-suppressed and is expected to be sub-dominant. Within this approximation, we find that, for the total cross section, NNLO QCD corrections are in the few percent range and, therefore, are comparable to NLO QCD corrections. We also find that the scale independence of the theoretical prediction for single-top production improves significantly once NNLO QCD corrections are included. Furthermore, we show how these results change if a cut on the transverse momentum of the top quark is applied and derive the NNLO QCD prediction for the ratio of single top and single anti-top production cross sections at the 8 TeV LHC.

description: In this study, we conduct a detailed analysis of the Košice meteorite fall (February 28, 2010), in order to derive a reliable law describing the mass distribution among the recovered fragments. In total, 218 fragments of the Košice meteorite, with a total mass of 11.285 kg, were analyzed. Bimodal Weibull, bimodal Grady and bimodal lognormal distributions are found to be the most appropriate for describing the Košice fragmentation process. Based on the assumption of bimodal lognormal, bimodal Grady, bimodal sequential and bimodal Weibull fragmentation distributions, we suggest that, prior to further extensive fragmentation in the lower atmosphere, the Košice meteoroid was initially represented by two independent pieces with cumulative residual masses of approximately 2 kg and 9 kg respectively. The smaller piece produced about 2 kg of multiple lightweight meteorite fragments with the mean around 12 g. The larger one resulted in 9 kg of meteorite fragments, recovered on the ground, including the two heaviest pieces of 2.374 kg and 2.167 kg with the mean around 140 g. Based on our investigations, we conclude that two to three larger fragments of 500-1000g each should exist, but were either not recovered or not reported by illegal meteorite hunters.

description: Exciton superfluid is a macroscopic quantum phenomenon in which large quantities of excitons undergo the Bose-Einstein condensation. Recently, exciton superfluid has been widely studied in various bilayer systems. However, experimental measurements only provide indirect evidence for the existence of exciton superfluid. In this article, by viewing the exciton in a bilayer system as an electric dipole, we provide a general theory for the electric dipole superconductivity, and derive the London-type and Ginzburg-Landau-type equations for the electric dipole superconductors. By using these equations, we discover the Meissner-type effect and the electric dipole current Josephson effect. These effects can provide direct evidence for the formation of the exciton superfluid state in bilayer systems and pave new ways to drive an electric dipole current.

description: Background: Urinary tract infections (UTIs) are common among diabetic patients, 60% of the patients with diabetes mellitus (DM) have risk of UTI and two third of them develop symptomatic or asymptomatic UTIs. The uropathogens may vary in their susceptibility to antimicrobials from place to place and time to time, therefore susceptibility pattern of predominant organisms against antimicrobials is essential. The aim of the study was to investigate the incidence of asymptomatic bacteriuria (ASB) and UTIs in clinically diagnosed diabetic patients and to determine the uropathogens responsible for ASB and UTIs as well as their antimicrobial susceptibility pattern. Methodology: An observational, prospective study was conducted at the Islamabad Social Security Hospital, Pakistan. Total 269 patients were recruited as per the study inclusion/exclusion criteria. Fasting blood glucose (FBG), blood sedimentation rate (BSR), urine routine examination (RE), abdominal ultrasound and hemoglobin-A1c (HbA1c) were examined in all patients to exclude other causes of urosepsis. Results: According to the study results 106 urine cultures were positive in the absence of urinary symptoms. Majority of the study subjects were around 50 years of age with an average glycosylated hemoglobin level of 8.98 g/dl. Urine culture and sensitivity test showed that E coli - Extended-spectrum beta-lactamases (ESBL) isolated in 39.63% was the most common organism sensitive to Tazobactam and Tiegecycline. E coli isolated in 32% was observed sensitive to levofloxacin, cefotaxime and tazobactam. Klebsiella (ESBL) isolated in 5.6% and found sensitive to tazobactum and amikacin. Klebsiella saprophyticus isolated in 3.77% with greater sensitivity to Tazobactum and cefixime while Enterococcus isolated in 5.6% mainly sensitive to minocycline and vancomycin. Majority of the isolated organisms were poorly sensitive or resistant to cefixime, quinolones and amoxiclav. Conclusion: Asymptomatic bactriuria is common in type 2 diabetic patients. The growth and sensitivity of microorganism reveal resistance and poor sensitivity to commonly used oral antibiotics therefore it is mandatory to treat UTI only after isolation of microorganisms according to culture and sensitivity to prevent resistant strains.

description: Social determinants of health (SDoH) have a significant impact on health outcomes and well-being. Addressing SDoH is the key to reducing healthcare inequalities and transforming a "sick care" system into a "health promoting" system. To address the SDOH terminology gap and better embed relevant elements in advanced biomedical informatics, we propose an SDoH ontology (SDoHO), which represents fundamental SDoH factors and their relationships in a standardized and measurable way. The ontology formally models classes, relationships, and constraints based on multiple SDoH-related resources. Expert review and coverage evaluation, using clinical notes data and a national survey, showed satisfactory results. SDoHO could potentially play an essential role in providing a foundation for a comprehensive understanding of the associations between SDoH and health outcomes and providing a path toward health equity across populations.

description: Abstract The generic scale-invariant theory of an axion and a dilaton coupled to gravity in d-dimensions is generalized to a ‘universal’ one-axion model with two dilatons that reproduces itself under consistent dimensional-reduction/truncation. Flat FLRW cosmologies are shown to correspond to trajectories of a three-dimensional autonomous dynamical system, which we analyse with a focus on accelerated cosmic expansion, deriving the precise swampland bounds that exclude eternal acceleration. We also show that for two sets of values of its three independent parameters, the model is a consistent truncation of maximal ‘massive’ supergravity theories arising from string/M-theory; for these maximal-supergravity parameter values the FLRW cosmologies include some with a transient de Sitter-like phase, but not the recurring de Sitter-like phase or eternal cosmic acceleration that is possible for other parameter values.

description: It is well known that aspects of the formation of localised states in a one-dimensional Swift--Hohenberg equation can be described by Ginzburg--Landau-type envelope equations. This paper extends these multiple scales analyses to cases where an additional nonlinear integral term, in the form of a convolution, is present. The presence of a kernel function introduces a new lengthscale into the problem, and this results in additional complexity in both the derivation of envelope equations and in the bifurcation structure. When the kernel is short-range, weakly nonlinear analysis results in envelope equations of standard type but whose coefficients are modified in complicated ways by the nonlinear nonlocal term. Nevertheless, these computations can be formulated quite generally in terms of properties of the Fourier transform of the kernel function. When the lengthscale associated with the kernel is longer, our method leads naturally to the derivation of two different, novel, envelope equations that describe aspects of the dynamics in these new regimes. The first of these contains additional bifurcations, and unexpected loops in the bifurcation diagram. The second of these captures the stretched-out nature of the homoclinic snaking curves that arises due to the nonlocal term.

description: The present work describes the effect of 1-nonyl-3-methylimidazolium bromide [C9mim][Br] and 1-dodecyl-3-methylimidazolium bromide [C12mim][Br] on aggregation behavior of anionic surfactant dioctyl sodium sulfosuccinate (NaAOT) in aqueous medium by employing different techniques such as conductivity measurement, UV–Visible spectroscopy and FT-IR spectroscopy. The conductivity data of anionic surfactant in the aqueous solution of surface-active ionic liquids is taken experimentally in the temperature range from 293.15 to 308.15 K with the interval of 5 K at various concentrations that is, (0.04, 0.08, 0.12, and 0.16) wt.% of both the SAILs. The critical micelle concentration (CMC) of NaAOT is detected to alter in the presence of both the SAILs. Temperature dependence of CMC obtained from conductivity measurements is utilized to evaluate various thermodynamic parameters of micellization such as, standard free energy of micellization (ΔGm0), standard enthalpy of micellization (ΔHm0), and standard entropy of micellization (ΔSm0). The UV–Visible spectroscopic study is utilized to confirm CMC values obtained from conductivity measurements, which are found to be in good agreement. FT-IR Spectra are recorded to analyze the structural changes that prevailed in both systems.

description: Nanomaterials have been developed to solve kinds of water pollution problems. Fluorinated graphene (FG) and multi-walled carbon nanotubes (MWCNTs) are used to improve the efficiency of oil/water separation of sponge via forming MWCNTs/FG/PU sponge in this work. The tests show that the two-dimensional FG can be adsorbed on the PU sponge, and one-dimensional MWCNTs can intertwine on the FG nanosheets as threads to fix on the skeletons of the PU sponge, which will form the micro-nano hierarchical structures and low surface energy surface. The surface contact angle of the MWCNTs/FG/PU sponge comes to the point of 158°, which indicates the MWCNTs/FG/PU sponge is superhydrophobic. The superhydrophobic MWCNTs/FG/PU sponge has outstanding ability to separate various oil/water mixtures effectively, and the corresponding absorbency of oils and organic reagents is over 15 g/g.

description: Atom interferometers are promising tools for precision measurement with applications ranging from geophysical exploration to tests of the equivalence principle of general relativity, or the detection of gravitational waves. Their optimal sensitivity is ultimately limited by their detection noise. We review resonant and near-resonant methods to detect the atom number of the interferometer outputs and we theoretically analyze the relative influence of various scheme dependent noise sources and the technical challenges affecting the detection. We show that for the typical conditions under which an atom interferometer operates, simultaneous fluorescence detection with a CCD sensor is the optimal imaging scheme. We extract the laser beam parameters such as detuning, intensity, and duration, required for reaching the atom shot noise limit.

description: An experimental study which aimed to analyze the pressure drop when the oil-water two-phase flow mixed with surfactant flows through porous medias was introduced. Porous media with the quartz sands mainly ranging from 0.2–1.2 mm and the oil-water two-phase system with Liaohe crude oil and water were prepared. Surfactant compounded with petroleum sulfonate (PS-30) and dodecyl dimethyl Betaine (BS-12) was used to improve the fluidity of oil-water mixture. The interfacial tension, viscosity and contact angle of the oil-water-surfactant mixture were tested. Then the pressure drop experiments were conducted, which considered three influence factors including the standard deviation of the granularity, the concentration of the surfactant and the ratio of oil to water. Forchheimer resistance model was used to fit the results, and the influence of three factors on the viscous resistance coefficient α−1 and inertial resistance coefficient C2 were discussed. The results indicated that the compound mixture PS-30/BS-12 is significantly better than other surfactants in terms of pressure drop, and the appropriate concentration of the surfactant is 0.3%. Pressure drop of the mixture can be well fitted by Forchheimer resistance model but α−1 and C2 still needed to be adjusted by test.

description: This study aimed to develop an oil-in-water emulsion with the presence of proteins, to be used as an ingredient in meat products. The emulsion can be used to increase the protein content of the final formulation, and the effect of the presence of proteins in the emulsion was assessed in terms of rheological and sensory properties of the meat products. Five emulsion formulations were designed, by changing the ratios of sodium caseinate, beef rumen, sunflower oil, and water. The emulsion formulated with 10% sodium caseinate, 10% beef rumen, 35% oil, and 45% water provided the optimal protein:fat/oil:water ratio and was suggested for further use as an additive in meat products. It was determined that the addition of 15–20% of O/W emulsion in the composition of forcemeats increases the water and fat-holding capacities and emulsifying ability to the maximum rate compared to the sample without O/W emulsion, which improves the consistency of minced meat. It was found that the addition of 15% of O/W emulsion increases the total number of PUFA up to 55.7%, MUFA up to 25.2%, while the content of SFA decreased to 19.2%.

description: A recent 15 parts-per-million (ppm) experiment on muonic hydrogen found a major discrepancy with QED and independent nuclear size determinations. Here we find a significant discrepancy in a different type of exotic atom, a medium-Z nucleus with two electrons. Investigation of the data collected is able to discriminate between available QED formulations and reveals a pattern of discrepancy of almost 6 standard errors of experimental results from the most recent theoretical predictions with a functional dependence proportional to Z^n where n=4. In both the muonic and highly charged systems, the sign of the discrepancy is the same, with the measured transition energy higher than predicted. Some consequences are possible or probable, and some are more speculative. This may give insight into effective nuclear radii, the Rydberg, the fine-structure constant or unexpectedly large QED terms.

description: In this study, investigations were conducted on the process of self-discharge of acidic car batteries. The dependence of battery discharge on environmental temperature has been studied. It was found that the self-discharge of batteries increases by up to 60% over 12 months when the temperature rises from +100C to +400С. Replacing the tin in the electrode alloy with a more electronegative metal has been shown to reduce the self-discharge process by up to 2% per month. Because, the self-discharge of electrode batteries made of lead-calcium alloy is relatively low, the consumption of working fluid is relatively low too and it will be possible to prepare them as the form of maintenance-free energy sources.

description: This article presents the results of obtaining biopolymers of chitin and chitosan from a new promising source- died honey bee apis mellifera. To obtain chitin, at the first stage, the protein (deproteination) and mineral (demineralization) constituents of subpestilence, i.e. put them in soluble state and removed. Demineralization was carried out with 2 M hudrochloric acid for 5 hours at room temperature. The process of deproteination is carried out by processing the crushed raw materials with 1 N sodium hudroxide solution for 1 hour at a temperature of 800С. Each process was accompanied by washing the raw materials to a natural wash water reaction (pH=7). At the next stage, chitin deacetylation under the influence of a 35% aqueous NaOH solution at a temperature of 850С for 4 hours produced chitosan, which is a high molecular weight glucosamine polymer, and dried at 50-550С. The resulting mass was decolorized with a 3% H2O2 solution and washed ethanol.

description: Heparinase I (EC 4.2.2.7), is an enzyme that cleaves heparin, showing great potential for eco-friendly production of low molecular weight heparin (LMWH). However, owing to its poor catalytic activity and thermal stability, the industrial application of heparinase I has been severely hindered. To improve the catalytic activity, we proposed to engineer both the substrate and Ca2+ binding domains of heparinase I. Several heparinases I from different organisms were selected for multiple sequence alignment and molecular docking to screen the key residues in the binding domain. Nine single-point mutations were selected to enhance the catalytic activity of heparinase I. Among them, T250D was the most highly active one, whereas mutations around Ca2+ binding domain yielded two active mutants. Mutant D152S/R244K/T250D with significantly increased catalytic activity was obtained by combined mutation. The catalytic efficiency of the mutant was 118,875.8 min−1·µM−1, which was improved 5.26 times. Molecular modeling revealed that the improved activity and stability of the mutants were probably attributed to the formation of new hydrogen bonds. The highly active mutant had great potential applications in industry and the strategy could be used to improve the performance of other enzymes. Improved catalytic activity of heparinase I by engineering the binding domains of substrate and Ca2+. The mutant D152S/R244K/T250D showed the highest catalytic performance. The increased hydrogen bonds attribute to the increased activity.

description: In this study, a modified metal hydroxides on surface of Lewatit resin (HMO @LM500, where M indicates to Al, Fe, Mn or Zn) were designed and used as efficient adsorbents for uranium (U(VI)) ions capture from aqueous solution. The prepared materials were characterized by using transform infrared spectroscopy, scanning electron microscope, energetic dispersive x-ray techniques. Batch adsorption methods were done to investigate all factors affecting adsorption process such as the effect of pH, concentration, contact time and temperature. Optimum values of each parameter were calculated as pH of 1.8, temperature of 298 K (25 °C), contact time of 60 min for the removal of uranium ions. Analysis within the nonlinear isotherm models indicates that the Liu model offers the best description for the equilibrium data since it has the highest R2 value and the lowest error analysis value when compared with the other models. The calculated adsorption capacity of Liu model is 217.06 mg g−1, whereas analysis within the nonlinear kinetic models indicate that pseudo-second-order behavior is involved. The thermodynamic examination of the equilibrium data proved that the adsorption process of U(VI) was found to be a spontaneous and exothermic process. The ΔH0 and ΔS0 parameters were calculated as −66.5827 kJ mol−1 and −0.2051 kJ mol−1 K−1, respectively. Therefore, the prepared adsorbent can be applied to capture of U(VI) ions from aqueous medium.

description: Gradient nanostructured metallic materials with a gradual change of grain boundary and dislocation density display unprecedent mechanical properties. Herein, we uncover a gradient of point defects concentration and concomitant gradient bandgap (E g) narrowing in metal oxide nanoparticles processed by a combination of severe shearing and frictional sliding deformation. Using the valence electron-energy loss spectroscopy technique, we find a gradual decrease of E g from 2.93 eV in the interior to 2.43 eV at the edge of the high-pressure torsion processed ZnO flake-shaped particle. This work paves the way to strain engineering of gradient-structured metal oxide semiconductors for unique functional properties. IMPACT STATEMENT We uncover a gradient of oxygen vacancy concentration and concomitant bandgap narrowing in an individual metal oxide nanoparticle processed by a combination of severe shearing and frictional sliding deformation.
A new relation between the zero of $A_{FB}$ in $B^0 \to K^* μ^+μ^-$ and the anomaly in $P_5^\prime$

description: We present two exact relations, valid for any dilepton invariant mass region (large and low-recoil) and independent of any effective Hamiltonian computation, between the observables $P_i$ and $P_i^{CP}$ of the angular distribution of the 4-body decay $B \to K^*(\to Kπ) l^+l^-$. These relations emerge out of the symmetries of the angular distribution. We discuss the implications of these relations under the (testable) hypotheses of no scalar or tensor contributions and no New Physics weak phases in the Wilson coefficients. Under these hypotheses there is a direct relation among the observables $P_{1}$,$P_2$ and $P_{4,5}^\prime$. This can be used as an independent consistency test of the measurements of the angular observables. Alternatively, these relations can be applied directly in the fit to data, reducing the number of free parameters in the fit. This opens up the possibility to perform a full angular fit of the observables with existing datasets. An important consequence of the found relations is that a priori two different measurements, namely the measured position of the zero ($q_0^2$) of the forward-backward asymmetry $A_{FB}$ and the value of $P_5^\prime$ evaluated at this same point, are related by $P_4^2(q_0^{2})+P_5^2(q_0^{2})=1$. Under the hypotheses of real Wilson coefficients and $P_4^\prime$ being SM-like, we show that the higher the position of $q_0^{2}$ the smaller should be the value of $P_5^\prime$ evaluated at the same point. A precise determination of the position of the zero of $A_{FB}$ together with a measurement of $P_4^\prime$ (and $P_1$) at this position can be used as an independent experimental test of the anomaly in $P_5^\prime$. We also point out the existence of upper and lower bounds for $P_1$, namely $P_5^{\prime 2}-1 \leq P_1 \leq 1-P_4^{\prime 2}$, which constraints the physical region of the observables.
