Simultaneous Measurement of the Half-Life and Spectral Shape of ^{115}In β Decay with an Indium Iodide Cryogenic Calorimeter.

Current bounds on the neutrino Majorana mass are affected by significant uncertainties in the nuclear calculations for neutrinoless double-beta decay. A key issue for a data-driven improvement of the nuclear theory is the actual value of the axial coupling constant g_{A}, which can be investigated through forbidden β decays. We present the first measurement of the 4th-forbidden β decay of ^{115}In with a cryogenic calorimeter based on indium iodide.

Localized Gradual Photomediated Brightness and Lifetime Increase of Superacid-Treated Monolayer MoS.

Monolayer semiconducting transition-metal dichalcogenides (S-TMDs) have been extensively studied as materials for next-generation optoelectronic devices due to their direct band gap and high exciton binding energy at room temperature. Under a superacid treatment of bis(trifluoromethane)sulfonimide (TFSI), sulfur-based TMDs such as MoS can emit strong photoluminescence (PL) with a photoluminescence quantum yield (PLQY) approaching unity. However, the magnitude of PL enhancement varies by more than 2 orders of magnitude in published reports.

A new approach for deducing rms proton radii from charge-changing reactions of neutron-rich nuclei and the reaction-target dependence.

We report the charge-changing cross sections (σ) of 24 p-shell nuclides on both hydrogen and carbon at about 900A MeV, of which Li, Be, B, N and O on hydrogen and Li on carbon are for the first time. Benefiting from the data set, we found a new and robust relationship between the scaling factor of the Glauber model calculations and the separation energies of the nuclei of interest on both targets. This allows us to deduce proton radii (R) for the first time from the cross sections on hydrogen.

Proton Distribution Radii of ^{16-24}O: Signatures of New Shell Closures and Neutron Skin.

The root mean square radii of the proton density distribution in ^{16-24}O derived from measurements of charge changing cross sections with a carbon target at ∼900A  MeV together with the matter radii portray thick neutron skin for ^{22-24}O despite ^{22,24}O being doubly magic. Imprints of the shell closures at N=14 and 16 are reflected in local minima of their proton radii that provide evidence for the tensor interaction causing them. The radii agree with ab initio calculations employing the chiral NNLO_{sat} interaction, though skin thickness predictions are challenged.

Adequacy of Antenatal Care during the COVID-19 Pandemic: Observational Study with Postpartum Women.

Objective:  The present study aimed to evaluate the antenatal care adequacy for women who gave birth at the University Hospital of Santa Catarina in Florianopolis (Brazil) during the COVID-19 pandemic, and to evaluate the association of adequacy with sociodemographic, clinical, and access characteristics.

Methods:  Data were collected between October and December 2020, including 254 patients who delivered in the University Hospital from Federal University of Santa Catarina and answered our questionnaires. Additional data were obtained from patients' antenatal booklets.

Radioactive Beams for Image-Guided Particle Therapy: The BARB Experiment at GSI.

Several techniques are under development for image-guidance in particle therapy. Positron (β) emission tomography (PET) is in use since many years, because accelerated ions generate positron-emitting isotopes by nuclear fragmentation in the human body. In heavy ion therapy, a major part of the PET signals is produced by β-emitters generated projectile fragmentation.

[Prenatal care for normal-risk pregnant women by obstetric nurses and midwives: cost-effectiveness from the perspective of the Supplementary Health System in Brazil].

In several countries, primary care for pregnant women is performed by obstetric nurses and/or midwives. In Brazil's Supplementary Health System (private health insurance and out-of-pocket care), coverage of prenatal care is mandatory and is performed by medical obstetricians. The objective of this study is to conduct a cost-effectiveness analysis, comparing clinical outcomes and costs associated with the incorporation of prenatal care by obstetric nurses and midwives in the Supplementary Health System, from the perspective of the operator of health plans as the payment source.

COVID-19-related deaths among women of reproductive age in Brazil: The burden of postpartum.

Objective: To compare risk of death due to COVID-19 among pregnant, postpartum, and non-pregnant women of reproductive age in Brazil, using the severe acute respiratory syndrome surveillance system (SARS-SS).

Methods: A secondary analysis was performed of the Brazilian official SARS-SS, with data retrieved up to August 17, 2020. Cases were stratified by pregnancy status, risk factors or co-morbidities, and outcome (death or recovery).

Patients Walking Faster After Anterior Cruciate Ligament Reconstruction Have More Gait Asymmetry.

Background: Gait asymmetries after anterior cruciate ligament reconstruction (ACLR) may lead to radiographic knee osteoarthritis. Slower walking speeds have been associated with biomarkers suggesting cartilage breakdown. The relationship between walking speed and gait symmetry after ACLR is unknown.

The impact of the COVID-19 pandemic on maternal mortality in Brazil: 523 maternal deaths by acute respiratory distress syndrome potentially associated with SARS-CoV-2.

During the study period, 523 pregnant or postpartum women died in Brazil due to confirmed COVID‐19 or undetermined etiology. This results in a projected COVID‐19 MMR of 17.5/100 000 or potentially even higher.

Risk factors for adverse outcomes among pregnant and postpartum women with acute respiratory distress syndrome due to COVID-19 in Brazil.

Data about timing of symptom onset and death (pregnancy or postpartum), gestational age, mode of birth, maternal age, comorbidities and/or risk factors, date of death, and place of death were retrieved when available.
