    The rate for Higgs (H) bosons production in association with either one (tH) or two (tt¯H) top quarks is measured in final states containing multiple electrons, muons, or tau leptons decaying to hadrons and a neutrino, using proton–proton collisions recorded at a center-of-mass energy of 13TeV by the CMS experiment. The analyzed data correspond to an integrated luminosity of 137fb−1. The analysis is aimed at events that contain H→WW, H→ττ, or H→ZZ decays and each of the top quark(s) decays either to lepton+jets or all-jet channels. Sensitivity to signal is maximized by including ten signatures in the analysis, depending on the lepton multiplicity. The separation among tH, tt¯H, and the backgrounds is enhanced through machine-learning techniques and matrix-element methods. The measured production rates for the tt¯H and tH signals correspond to 0.92±0.19(stat)+0.17−0.13(syst) and 5.7±2.7(stat)±3.0(syst) of their respective standard model (SM) expectations. The corresponding observed (expected) significance amounts to 4.7 (5.2) standard deviations for tt¯H, and to 1.4 (0.3) for tH production. Assuming that the Higgs boson coupling to the tau lepton is equal in strength to its expectation in the SM, the coupling yt of the Higgs boson to the top quark divided by its SM expectation, κt=yt/ySMt, is constrained to be within −0.9<κt<−0.7 or 0.7<κt<1.1, at 95% confidence level. This result is the most sensitive measurement of the tt¯H production rate to date.SCOAP

    Not AvailableEight diverse homozygous tomato parental lines were crossed in half diallel fashion, to develop twenty-eight hybrids. These 28 F1 hybrids and their parents were evaluated at Department of Vegetable Science, C.H.F., CAU, Pasighat, A.P. during 2014-2015. A wide range of variation was observed for fruit yield and related constituents. The high PCV, GCV, ECV, heritability (broad sense), and genetic advance over percentage of mean were recorded for fruit yield per plant. DVRT-1 × CHFT-50 was found earliest flowering in 50.67 days and earliest harvest in 70.00 days. Earliest flowering concurrent with early fruit set that are expressed in all hybrids under studied. The highest fruit yield was established in DVRT-2 × CHFT-77 (9.13 kg), followed by DVRT-2 × H-86 (6.86 kg) and CHFT-60 × CHFT-71 (5.92 kg). Among the hybrids, the fruit weight was correlated with fruit yield. Cross, H-86 × CHFT-50 was given high yield along with quality characters. The hybrid DVRT-2 × CHFT-77, H-86 × CHFT-50 and CHFT-60 × CHFT-71 were found best regarding fruit yield, quality traits and earliness. Therefore, the current study showed that hybrid breeding approaches strengthening to improve yield, earliness together with qualities.Not Availabl

    Patterning Cr Film by Passing Electric Current through a Traversing Pointy Stylus: Introduction to Electrolithography and Its Prospects

    No full text
    Here, we introduce electrolithography, which is a recently developed lithography technique. Upon passage of electric current through a pointy cathode electrode placed on Cr film leads to formation and liquefaction of a Cr compound, which then flows away from the cathode in a radially symmetric fashion, thereby removing the Cr layer. If the pointy electrode, akin to a stylus, is traversed along a path, a trench will be patterned in the Cr film, which can then be transferred to other materials. Firstly, we describe the process of electrolithography and then we discuss the effects of the force applied on the stylus and the polymer layer placed in between substrate and Cr film on this lithography process. Finally, we discuss future prospects of electrolithography

    Falcipain-2 (FP-2) is one of the main haemoglobinase of P. falciparum which is an important molecular target for the treatment of malaria. In this study, we have screened alkaloids to identify potential inhibitors against FP-2 since alkaloids possess great potential as anti-malarial agents. A total of 340 alkaloids were considered for the study using a series of computational pipelines. Initially, pharmacokinetics and toxicity risk assessment parameters were applied to screen compounds. Subsequently, molecular docking algorithms were utilised to understand the binding efficiency of alkaloids against FP-2. Further, oral toxicity prediction was done using the pkCSM tool, and 3D pharmacophore features were analysed using the PharmaGist server. Finally, MD simulation was performed for Artemisinin and the top 3 drug candidates (Noscapine, Reticuline, Aclidinium) based on docking scores to understand the functional impact of the complexes, followed by a binding site interaction residues study. Overall analysis suggests that Noscapine conceded good pharmacokinetics and oral bioavailability properties. Also, it showed better binding efficiency with FP-2 when compared to Artemisinin. Interestingly, structure alignment analysis with artemisinin revealed that Noscapine, Reticuline, and Aclidinium might possess similar biological action. Molecular dynamics and free energy calculations revealed that Noscapine could be a potent antimalarial agent targeting FP-2 that can be used for the treatment of malaria and need to be studied experimentally in the future

    Relationship between biochemical parameters of mineral bone disease and static bone histomorphometry in chronic kidney disease patients on hemodialysis: An Indian cross-section study

    No full text
    Aim: We estimated the relationship between routine biochemical laboratory parameters with static bone histomorphometric parameters and their high and low bone turnover capacity predictability in hemodialysis patients. Method: It was a single-center cross-sectional study, included 28 hemodialysis patients. The routine biochemical parameters measured including calcium, phosphorous, alkaline phosphatase, intact PTH, and 25-hydroxycholecalciferol. The histomorphometric parameters assessed were osteoblasts perimeter, osteoclast perimeter, eroded perimeter, osteoid perimeter, bone fibrosis and bone volume. Result: Total 28 hemodialysis patients underwent bone biopsy. Seventy percent were male, with a mean age was 33.07 ± 10.42 yrs; serum alkaline phosphatase was 219.10 ± 311.3 IU/ml; vitamin D was 18.18 ± 9.56 ng/ml, and intact PTH was 650.7 ± 466.0 pg/ml. Intact PTH had a significant positive association with osteoblast, osteoclast, eroded surface, and osteoid perimeter. Serum alkaline phosphatase had a significant relationship with bone fibrosis (r = 0.525, p-value = 0.004). Intact PTH was significantly higher in females than males (1078.75 ± 533.04 vs. 479.6 ± 309.83; p-value = 0.004). The osteoid surface was significantly high in females compared to males (p = 0.038). Age had a significant impact on osteoblast and eroded surface (p = 0.008 and p = 0.031, respectively). Intact PTH is a reliable biomarkers for bone turnover compare to ALP (p < 0.001 and p = 0.554, respectively). Conclusion: Intact PTH strongly associated with bone formation, bone resorption parameters. Gender and age had significant impact on static histomorphometric parameters in our study

    Detection and analysis of volatile organic compounds' (VOCs) biomarkers lead to improvement in healthcare diagnosis and other applications such as chemical threat detection and food quality control. Here, we report on tri-molybdenum phosphide (Mo3P) and multiwalled carbon nanotube (MWCNT) junction-based vapor quantum resistive sensors (vQRSs), which exhibit more than one order of magnitude higher sensitivity and superior selectivity for biomarkers in comparison to pristine MWCNT junctions based vQRSs. Transmission electron microscope/scanning tunneling electron microscope with energy dispersive x-ray spectroscopy, x-ray diffraction, and x-ray photoelectron spectroscopy studies reveal the crystallinity and the presence of Mo and P elements in the network. The presence of Mo3P clearly enhanced the performance of vQRS as evidenced in sensitivity and selectivity studies. The vQRSs are stable over extended periods of time and are reproducible, making them a potential candidate for sensing related applications.All authors have read and approved the final manuscript.

    An operationally simple and high yielding protocol for the synthesis of polyfunctional pyrazoles has been developed through one-pot, three-component coupling of aldehydes, 1,3-dicarbonyls, and diazo compounds as well as tosyl hydrazones. The reaction proceeds through a tandem Knoevenagel condensation, 1,3-dipolar cycloaddition, and transition metal-free oxidative aromatization reaction sequence utilizing molecular oxygen as a green oxidant. The scope of the reaction was studied by varying the aldehyde, 1,3-dicarbonyl, and diazo component individually
