A search is conducted for a low-mass charged Higgs boson produced in a top quark decay and subsequently decaying into a charm and a strange quark. The data sample was recorded in proton-proton collisions at s=13 TeV by the CMS experiment at the LHC and corresponds to an integrated luminosity of 35.9 fb−1. The search is performed in the process of top quark pair production, where one top quark decays to a bottom quark and a charged Higgs boson and the other to a bottom quark and a W boson. With the W boson decaying to a charged lepton (electron or muon) and a neutrino, the final state comprises an isolated lepton, missing transverse momentum, and at least four jets, of which two are tagged as b jets. To enhance the search sensitivity, one of the jets originating from the charged Higgs boson is required to satisfy a charm tagging selection. No significant excess beyond standard model predictions is found in the dijet invariant mass distribution. An upper limit in the range 1.68%–0.25% is set on the branching fraction of the top quark decay to the charged Higgs boson and bottom quark for a charged Higgs boson mass between 80 and 160 GeV.

The paper presents a short overview of the theoretical, numerical and experimental works on the critical behaviour of a dilute polymer solution of long-flexible polymer chains confined in semi-infinite space restricted by a surface or in a slit geometry of two parallel walls with different adsorbing or repelling properties in respect for polymers as well as in a solution of mesoscopic spherical colloidal particles of one sort or two different sorts. We discuss the application of the massive field theory approach in a fixed space dimensions d = 3 up to one loop order for such topics as: (a) the investigation of the elastic properties of real polymer chain immersed in a good solvent and anchored by one end to the surface and with other end being under tension of the external applied force as it is usually takes place in the single - molecule force spectroscopy experiments;(b) the calculation of the monomer density profiles, the depletion interaction potentials and the depletion forces which arise in a dilute polymer solution immersed in confined geometries, like slit of two parallel walls with different adsorbing or repelling properties in respect for polymers;(c) the investigation of monomer density profiles and the depletion forces which arise in the polymer-colloid mixtures in the case of the mesoscopic spherical colloidal particles of one sort or two different sorts. The presented results give possibility better to understand the complexity of physical effects arising from confinement and indicate about the interesting and nontrivial behavior of linear polymer chains in confined geometries and are in good qualitative and quantitative agreement with previous theoretical investigations, results of Density Functional Theory (DFT), Monte Carlo (MC) simulations and experimental data based on the single molecular atomic force spectroscopy (AFM) and the total internal reflection microscopy (TIRM). Besides, the obtained results have important practical applications for be

Many different solutions to predicting the cognate epitope target of a T-cell receptor (TCR) have been proposed. However several questions on the advantages and disadvantages of these different approaches remain unresolved, as most methods have only been evaluated within the context of their initial publications and data sets. Here, we report the findings of the first public TCR-epitope prediction benchmark performed on 23 prediction models in the context of the ImmRep 2022 TCR-epitope specificity workshop. This benchmark revealed that the use of paired-chain alpha-beta, as well as CDR1/2 or V/J information, when available, improves classification obtained with CDR3 data, independent of the underlying approach. In addition, we found that straight-forward distance-based approaches can achieve a respectable performance when compared to more complex machine-learning models. Finally, we highlight the need for a truly independent follow-up benchmark and provide recommendations for the design of such a next benchmark.

Results are reported from an amplitude analysis of the B+→D+D−K+ decay. The analysis is carried out using LHCb proton-proton collision data taken at s=7, 8, and 13 TeV, corresponding to a total integrated luminosity of 9 fb−1. In order to obtain a good description of the data, it is found to be necessary to include new spin-0 and spin-1 resonances in the D−K+ channel with masses around 2.9 GeV/c2, and a new spin-0 charmonium resonance in proximity to the spin-2 χc2(3930) state.

We present an angular analysis of the B+ → K∗+(→ KS0π+)µ+µ− decay using 9 fb−1 of pp collision data collected with the LHCb experiment. For the first time, the full set of CP-averaged angular observables is measured in intervals of the dimuon invariant mass squared. Local deviations from Standard Model predictions are observed, similar to those in previous LHCb analyses of the isospin-partner B0 → K∗0µ+µ− decay. The global tension is dependent on which effective couplings are considered and on the choice of theory nuisance parameters. © 2020, CC BY.

The relative branching fractions of B+→h+h′+h′− decays, where h(′) is a pion or kaon, are measured. The analysis is performed with a data sample, collected with the LHCb detector, corresponding to an integrated luminosity of 3.0 fb−1 of pp collisions. The results obtained improve significantly on previous measurements of these quantities, and are important for the interpretation of Dalitz plot analyses of three-body charmless hadronic decays of B+ mesons.

Background: The COVID-19 pandemic highlighted gaps in health surveillance systems, disease prevention, and treatment globally. Among the many factors that might have led to these gaps is the issue of the financing of national health systems, especially in low-income and middle-income countries (LMICs), as well as a robust global system for pandemic preparedness. We aimed to provide a comparative assessment of global health spending at the onset of the pandemic;characterise the amount of development assistance for pandemic preparedness and response disbursed in the first 2 years of the COVID-19 pandemic;and examine expectations for future health spending and put into context the expected need for investment in pandemic preparedness. Methods: In this analysis of global health spending between 1990 and 2021, and prediction from 2021 to 2026, we estimated four sources of health spending: development assistance for health (DAH), government spending, out-of-pocket spending, and prepaid private spending across 204 countries and territories. We used the Organisation for Economic Co-operation and Development (OECD)'s Creditor Reporting System (CRS) and the WHO Global Health Expenditure Database (GHED) to estimate spending. We estimated development assistance for general health, COVID-19 response, and pandemic preparedness and response using a keyword search. Health spending estimates were combined with estimates of resources needed for pandemic prevention and preparedness to analyse future health spending patterns, relative to need. Findings: In 2019, at the onset of the COVID-19 pandemic, US$9·2 trillion (95% uncertainty interval [UI] 9·1–9·3) was spent on health worldwide. We found great disparities in the amount of resources devoted to health, with high-income countries spending $7·3 trillion (95% UI 7·2–7·4) in 2019;293·7 times the $24·8 billion (95% UI 24·3–25·3) spent by low-income countries in 2019. That same year, $43·1 billion in development assistance was provided

Single-crystal zinc oxide nanowires (ZnO NWs) were successfully fabricated by low-temperature hydrothermal method using zinc acetate and hexamethulenetramine. The possible grown mechanism of the influence of precursor concentration on ZnO NWs was discussed in the detail. The as-grown single crystal ZnO NWs structural were investigated by X-ray diffraction (XRD), transmission electron microscopy (TEM) and field-emission scanning electron microscopy (FE-SEM). The XRD and TEM resulted showed that the structure of ZnO NWs was wurtzite structure. The growth rate and morphology of ZnO NWs was depended on the precursor concentration. Furthermore, their hydrogen gas sensing characteristics were systematically investigated and discussed in this paper.
