The differential production cross sections of B^{±} mesons are measured via the exclusive decay channels B^{±}→J/ψK^{±}→μ^{+}μ^{-}K^{±} as a function of transverse momentum in pp and Pb-Pb collisions at a center-of-mass energy sqrt[s_{NN}]=5.02  TeV per nucleon pair with the CMS detector at the LHC. The pp(Pb-Pb) data set used for this analysis corresponds to an integrated luminosity of 28.

Results are reported from a search for supersymmetric particles in proton-proton collisions in the final state with a single lepton, multiple jets, including at least one b-tagged jet, and large missing transverse momentum. The search uses a sample of proton-proton collision data at sqrt[s]=13  TeV recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 35.9  fb^{-1}.

Shadow Mask technology has been used over the years for resistless patterning and to pattern on unconventional surfaces, fragile substrate and biomaterial. In this work, we are presenting a novel method to fabricate high aspect ratio (15:1) three-dimensional (3D) Nickel (Ni) shadow mask with vertical pattern length and width of 1.2 mm and 40 m respectively.

Objective: The current study focuses on social risk and resilience in an adolescent population with chronic pain. Prior research identifies parental cognitions and behaviors as influential in youths' experiences of chronic pain and pain-related disability. Adolescent development is characterized by greater autonomy from parents and an increased emphasis on peer relationships.

Two series of thermosensitive hydrogels were synthesized by copolymerizing N-isopropylacrylamide (NIPAAm) with various contents of novel hydrophobic crosslinkers, curcumin multiacrylate (CMA) and quercetin multiacrylate (QMA). The compositions of the resulting hydrogels were characterized using solid state-NMR (ss-NMR), and the temperature dependent swelling behavior and lower critical solution temperature (LCST) were characterized using swelling studies and differential scanning calorimetry (DSC). Increasing the crosslinker content resulted in a significant decrease in the LCST and swelling ratio of hydrogels, which could be attributed to the increased hydrophobicity introduced by CMA or QMA.

The production of jets in association with Z bosons, reconstructed via the μ^{+}μ^{-} and e^{+}e^{-} decay channels, is studied in pp and, for the first time, in Pb-Pb collisions. Both data samples were collected by the CMS experiment at the LHC, at a nucleon-nucleon center-of-mass energy of 5.02 TeV.

Article Synopsis
  • The study measures normalized double-differential cross sections for top quark pair production in proton-proton collisions at 8 TeV using data from the CMS experiment at the LHC, covering an integrated luminosity of 19.7 fb⁻¹.
  • The analysis focuses on the dilepton final state, examining how the production cross section varies with different kinematic variables of the top quark and associated systems.
  • The findings align with theoretical predictions from quantum chromodynamics and Monte Carlo simulations, especially when incorporating the latest parton distribution functions, indicating a notable influence on the gluon distribution.

Article Synopsis
  • A new measurement of the top quark mass is reported, focusing on single top quark events produced through the electroweak channel using data from the CMS detector at the LHC with a center-of-mass energy of 8 TeV.
  • The analysis involves reconstructing top quark candidates via their decay into a W boson (which decays to a muon and a neutrino) and a b quark, thus enhancing the sample purity and reducing interference from top quark pair production.
  • The final measurement aligns with the current world average, providing a unique contribution to future averages by reducing systematic uncertainties linked to single top quark processes.

Searches are presented for direct production of top or bottom squark pairs in proton-proton collisions at the CERN LHC. Two searches, based on complementary techniques, are performed in all-jet final states that are characterized by a significant imbalance in transverse momentum. An additional search requires the presence of a charged lepton isolated from other activity in the event.

Inositol hexakisphosphate kinases (IP6Ks) are enzymes that synthesise the inositol pyrophosphate 5-diphosphoinositol pentakisphosphate (5-IP), which is known to regulate several physiological processes. Deletion of IP6K1, but not other IP6K isoforms, causes sterility in male mice. Here, we present a detailed investigation of the specific function of IP6K1 in spermatogenesis.

Over the last several years, there has been a growing interest in neural implants for the study and diagnostics of neurological disorders as well as for the symptomatic treatment of central nervous system related diseases. One of the major challenges is the trade-off between small electrode sizes for high selectivity between single neurons and large electrode-tissue interface areas for excellent stimulation and recording properties. This paper presents an approach of increasing the real surface area of the electrodes by creating a surface microstructure.

Intracerebral hemorrhage (ICH) contributes to 10-15% of all strokes and is a high risk factor for morbidity and mortality as compared to other subtypes of stroke, that is, cerebral ischemia and subarachnoid hemorrhage. Oxidative stress (OS)-induced neuroinflammation and neuronal cell death contribute towards the hallmarks of ICH. Spared antioxidant levels, increased inflammatory cytokines and free radicals in ICH lead to neuronal death and exaggerate the hallmarks of ICH.

Background: In developing countries like Nepal, 90% ethanol is cheap and is available in most hospitals. The unavailability of isopropyl alcohol (IPA) in these settings led us to compare the efficacy between 90% ethanol and isopropyl alcohol pads in reducing the bacterial contamination of diaphragm of stethoscope.

Methods: A randomized blinded experimental study was carried out to determine the difference between cleaning stethoscopes with 90% ethanol and IPA.

Background: Indeed, intracerebral hemorrhage (ICH) account for only 15% of all strokes but it is one of the most devastating subtype of stroke associated with behavioral, cognitive and neurological deficits. The primary cause of neurological deficits in ICH is the hematoma growth, generation of free radicals, inflammatory cytokines and exhausting endogenous anti-oxidant machinery. It has been found that neuroinflammation following ICH leads to exaggeration of hallmarks of ICH.
