α-Cyclodextrin affects the acid-base properties of octanoic acid/sodium octanoate

The interaction of octanoic acid and its conjugate base sodium octanoate with α-cyclodextrin was studied by 1H NMR and isothermal titration calorimetry, respectively, at 298.15 K. The results are in agreement with a 1:1 stoichiometry in the complex. The binding of octanoate with α-cyclodextrin is characterized by a positive entropy, stressing the relevance of hydrophobic interactions. Based on the

Constraints on Higgs boson properties using WW∗(→ eνμν) jj production in 36.1fb-1 of √s=13 TeV pp collisions with the ATLAS detector

This article presents the results of two studies of Higgs boson properties using the WW∗(→ eνμν) jj final state, based on a dataset corresponding to 36.1 fb - 1 of s=13 TeV proton–proton collisions recorded by the ATLAS experiment at the Large Hadron Collider. The first study targets Higgs boson production via gluon–gluon fusion and constrains the CP properties of the effective Higgs–gluon interac

Access to health and rehabilitation services for persons with disabilities in Sierra Leone – focus group discussions with stakeholders

Background: In Sierra Leone persons with disabilities are at higher risk of living in poverty and have poor access to a fragile healthcare and rehabilitation services. The aim was to explore stakeholders’ perceptions of access to health and rehabilitation services for persons with disabilities in Sierra Leone. Methods: Seven focus group discussions, including stakeholders working within the field

Fundamental effective temperature measurements for eclipsing binary stars-III. SPIRou near-infrared spectroscopy and CHEOPS photometry of the benchmark G0V star EBLM J0113+31

EBLM J0113+31 is a moderately bright (V = 10.1), metal-poor ([Fe/H] ≈-0.3) G0V star with a much fainter M dwarf companion on a wide, eccentric orbit (= 14.3 d). We have used near-infrared spectroscopy obtained with the SPIRou spectrograph to measure the semi-amplitude of the M dwarf's spectroscopic orbit, and high-precision photometry of the eclipse and transit from the CHEOPS and TESS space missi

Alpha-Amylase Inhibits Cell Proliferation and Glucose Uptake in Human Neuroblastoma Cell Lines

The present article describes a study of the effects of alpha-amylase (α-amylase) on the human neuroblastoma (NB) cell lines SH-SY5Y, IMR-32, and LA-N-1. NB is the most common malignancy diagnosed in infants younger than 12 months. Some clinical observations revealed an inverse association between the risk of NB development and breastfeeding. α-Amylase which is present in breast milk was shown to

Drivers or passengers? A taxonomy of multinationals’ approaches to corporate social responsibility implementation in developing markets

Purpose: The purpose of this study is to conduct a systematic literature review that illuminates the current state of knowledge regarding the specific approaches by which multinational corporations (MNCs) implement corporate social responsibility (CSR) on the subsidiary level in developing countries. Design/methodology/approach: Even though substantial scholarly work has been made to outline MNCs'

Polygenic risk modeling for prediction of epithelial ovarian cancer risk

Polygenic risk scores (PRS) for epithelial ovarian cancer (EOC) have the potential to improve risk stratification. Joint estimation of Single Nucleotide Polymorphism (SNP) effects in models could improve predictive performance over standard approaches of PRS construction. Here, we implemented computationally efficient, penalized, logistic regression models (lasso, elastic net, stepwise) to individ

Know Thyself! Predicting Subjective Well-Being from personality estimation discrepancy and self-insight

Discrepancies in views of the Self are suggested to be negatively related to well-being (Higgins, 1987). In the present study, we used a novel concept, Personality Estimation Discrepancy (PED), to test this classic idea. PED is defined as the computed difference between how one view oneself (Self-Perceived Personality) and a standard Big Five test (IPIP-NEO-30). In a pre-registered (osf.io) UK onl

A linear implicit Euler method for the finite element discretization of a controlled stochastic heat equation

We consider a numerical approximation of a linear quadratic control problem constrained by the stochastic heat equation with nonhomogeneous Neumann boundary conditions. This involves a combination of distributed and boundary control, as well as both distributed and boundary noise. We apply the finite element method for the spatial discretization and the linear implicit Euler method for the tempora

Reduced order design and investigation of intakes for high speed propulsion systems

Ramjet propulsion is commonly preferred to power supersonic and hypersonic vehicles for cruising faster than Mach 3. This is an elegant solution owing to the lean architecture which does not embody any rotating parts. Although the geometry of the engine is simple as compared to turbine based configurations, the flow physics through the engine duct is quite complex and the flow speeds modulate betw

An Auditable Constraint Programming Solver

We describe the design and implementation of a new constraint programming solver that can produce an auditable record of what problem was solved and how the solution was reached. As well as a solution, this solver provides an independently verifiable proof log demonstrating that the solution is correct. This proof log uses the VeriPB proof system, which is based upon cutting planes reasoning with

Conforming to Collective Action : The Impact of Rejection, Personality and Norms on Participation in Protest Activity

Social norms guide humans’ everyday behavior, and previous research has shown that social norms consistently predict some forms of political participation. Failure to conform to norms may lead to deviation and possible rejection, which humans innately seek to avoid since it threatens their need for belongingness. Following an episode of rejection, individuals are therefore likely to become increas

Direct observation of the dead-cone effect in quantum chromodynamics

In particle collider experiments, elementary particle interactions with large momentum transfer produce quarks and gluons (known as partons) whose evolution is governed by the strong force, as described by the theory of quantum chromodynamics (QCD)1. These partons subsequently emit further partons in a process that can be described as a parton shower2, which culminates in the formation of detectab

Preoperative Risk Score for Early Mortality After Up-Front Pancreatic Cancer Surgery : A Nationwide Cohort Study

Background: Pancreatic ductal adenocarcinoma is a highly fatal malignancy. The aim was to identify preoperative factors for early mortality in up-front resectable patients following pancreatoduodenectomy (PD) and develop an early mortality risk score. Methods: Patients registered in the Swedish National Registry for Pancreatic and Periampullary Cancer were included. Relevant preoperative factors (

Measurements of Higgs bosons decaying to bottom quarks from vector boson fusion production with the ATLAS experiment at √s=13TeV

The paper presents a measurement of the Standard Model Higgs Boson decaying to b-quark pairs in the vector boson fusion (VBF) production mode. A sample corresponding to 126 fb - 1 of s=13TeV proton–proton collision data, collected with the ATLAS experiment at the Large Hadron Collider, is analyzed utilizing an adversarial neural network for event classification. The signal strength, defined as the

Observation of photon-induced W+W− production in pp collisions at s=13 TeV using the ATLAS detector

This letter reports the observation of photon-induced production of W-boson pairs, γγ→WW. The analysis uses 139 fb−1 of LHC proton–proton collision data taken at s=13 TeV recorded by the ATLAS experiment during the years 2015–2018. The measurement is performed selecting one electron and one muon, corresponding to the decay of the diboson system as WW→e±νμ∓ν final state. The background-only hypothe
