Proton transport through nanoscale corrugations in two-dimensional crystals.

Defect-free graphene is impermeable to all atoms and ions under ambient conditions. Experiments that can resolve gas flows of a few atoms per hour through micrometre-sized membranes found that monocrystalline graphene is completely impermeable to helium, the smallest atom. Such membranes were also shown to be impermeable to all ions, including the smallest one, lithium.

Anticipated benefits and challenges of implementing group care in Suriname's maternity and child care sector: a contextual analysis.

Environmental health impacts and inequalities in green space and air pollution in six medium-sized European cities.

Background: The GoGreenRoutes project aims to introduce co-created nature-based solutions (NBS) to enhance environmental quality in six medium-sized cities (Burgas, Lahti, Limerick, Tallinn, Umeå, and Versailles). We estimated the mortality and economic impacts attributed to suboptimal exposure to green space and air pollution, economic impacts, and the distribution thereof the adult population by socioeconomic status.

Methods: We retrieved data from publicly accessible databases on green space (NDVI and % Green Area), air pollution (NO and PM) and population (≥20 years, n = 804,975) at a 250m × 250m grid-cell level, and mortality for each city for 2015.

Azimuthal Correlations within Exclusive Dijets with Large Momentum Transfer in Photon-Lead Collisions.

The structure of nucleons is multidimensional and depends on the transverse momenta, spatial geometry, and polarization of the constituent partons. Such a structure can be studied using high-energy photons produced in ultraperipheral heavy-ion collisions. The first measurement of the azimuthal angular correlations of exclusively produced events with two jets in photon-lead interactions at large momentum transfer is presented, a process that is considered to be sensitive to the underlying nuclear gluon polarization.

Case report: the effects of cerebellar tDCS in bilingual post-stroke aphasia.

Transcranial Direct Current Stimulation may be a useful neuromodulation tool for enhancing the effects of speech and language therapy in people with aphasia, but research so far has focused on monolinguals. We present the effects of 9 sessions of anodal cerebellar tDCS (ctDCS) coupled with language therapy in a bilingual patient with chronic post-stroke aphasia caused by left frontal ischemia, in a double-blind, sham-controlled within-subject design. Language therapy was provided in his second language (L2).

Measurements of the Higgs boson production cross section and couplings in the W boson pair decay channel in proton-proton collisions at .

Production cross sections of the standard model Higgs boson decaying to a pair of W bosons are measured in proton-proton collisions at a center-of-mass energy of 13. The analysis targets Higgs bosons produced via gluon fusion, vector boson fusion, and in association with a W or Z boson. Candidate events are required to have at least two charged leptons and moderate missing transverse momentum, targeting events with at least one leptonically decaying W boson originating from the Higgs boson.

Cerebrospinal fluid inflammatory biomarkers for disease progression in Alzheimer's disease and multiple sclerosis: a systematic review.

Unlabelled: Inflammatory processes are involved in the pathophysiology of both Alzheimer's disease (AD) and multiple sclerosis (MS) but their exact contribution to disease progression remains to be deciphered. Biomarkers are needed to define pathophysiological processes of these disorders, who may increasingly co-exist in the elderly generations of the future, due to the rising prevalence in both and ameliorated treatment options with improved life expectancy in MS. The purpose of this review was to provide a systematic overview of inflammatory biomarkers, as measured in the cerebrospinal fluid (CSF), that are associated with clinical disease progression.

Biomimetic models of fish gill rakers as lateral displacement arrays for particle separation.

Ram suspension-feeding fish, such as herring, use gill rakers to separate small food particles from large water volumes while swimming forward with an open mouth. The fish gill raker function was tested using 3D-printed conical models and computational fluid dynamics simulations over a range of slot aspect ratios. Our hypothesis predicting the exit of particles based on mass flow rates, dividing streamlines (i.

The results are found to agree with the predictions of the standard model.

It takes two to tango: the recruiter's role in accepting or refusing to participate in group antenatal care among pregnant women-an exploration through in-depth interviews.

Objective: The purpose of this study was to explore how women are recruited for group antenatal care (GANC) in primary care organisations (PCOs), what elements influence the behaviour of the recruiter, and what strategies recruiters use to encourage women to participate.

Method: Using a qualitative research design, we conducted 10 in-depth interviews with GANC facilitators working in PCOs. Selected constructs of the domains of the Consolidated Framework for Implementation Research and the Theoretical Domains Framework helped to develop interview questions and raise awareness of important elements during interviews and thematic analyses.

CMS pythia 8 colour reconnection tunes based on underlying-event data.

New sets of parameter tunes for two of the colour reconnection models, quantum chromodynamics-inspired and gluon-move, implemented in the pythia  8 event generator, are obtained based on the default CMS pythia  8 underlying-event tune, CP5. Measurements sensitive to the underlying event performed by the CMS experiment at centre-of-mass energies and 13, and by the CDF experiment at 1.96 are used to constrain the parameters of colour reconnection models and multiple-parton interactions simultaneously.

The Pre-Implementation Phase of a Project Seeking to Deliver a Community-Based CVD Prevention Intervention (SPICES-Sussex): A Qualitative Study Exploring Views and Experience Relating to Intervention Development.

Background.: Community-led health care interventions may be an effective way to tackle cardiovascular disease (CVD) risk factors, especially in materially deprived communities where health care resources are stretched and engagement with institutions is often low. To do so effectively and equitably, interventions might be developed alongside community members through community engagement.

Maternal satisfaction with reduced postnatal length of stay in Brussels: evidence from the KOZI&Home program.

Background: Reducing the length of stay (LOS) after childbirth is a trend, including cost savings, a more family-centered approach and lower risk for nosocomial infection. Evaluating the impact of reduced LOS is important to improve the outcomes of care, which include maternal satisfaction. The aim of this study was to compare the maternal satisfaction, before and after the reduced LOS.

Implications of a Reduced Length of Postpartum Hospital Stay on Maternal and Neonatal Readmissions, an Observational Study.

Introduction: Reducing the Length Of postpartum Stay (LOS) is associated with lower hospital costs, a major reason for initiating federal projects in Belgium. Disadvantages following the reduction of LOS are the risks of maternal and neonatal readmissions. This study compares readmissions with or without reduced LOS, by introducing the KOZI&Home program in the university hospital Brussels.

Asynchronous locking in metamaterials of fluids of light and sound.

Lattices of exciton-polariton condensates represent an attractive platform for the study and implementation of non-Hermitian bosonic quantum systems with strong non-linear interactions. The possibility to actuate on them with a time dependent drive could provide for example the means to induce resonant inter-level transitions, or to perform Floquet engineering or Landau-Zener-Stückelberg state preparation. Here, we introduce polaromechanical metamaterials, two-dimensional arrays of μm-sized traps confining zero-dimensional light-matter polariton fluids and GHz phonons.
