Household Transmission and Genomic Diversity of Respiratory Syncytial Virus (RSV) in the United States, 2022-2023.

Background: Household transmission of respiratory viruses may drive community spread. Few recent studies have examined household respiratory syncytial virus (RSV) transmission in the United States.

Collective States of α-Sexithiophene Chains Inside Boron Nitride Nanotubes.

The optical excitation of close-by molecules can couple into collective states giving rise to phenomena such as ultrafast radiative decay and superradiance. Particularly intriguing are one-dimensional molecular chains that form inside nanotube templates, where the tubes align molecules into single- and multifile chains. The resulting collective excitations have strong fluorescence and shifted emission/absorption energies compared to the molecular monomer.

Mothers' and fathers' emotion socialization: Longitudinal relations with toddlers' social competence.

We examined longitudinal direct associations between mothers' and fathers' emotion socialization behaviors (ESB) at 18 and 24 months and toddlers' social competence (SC) at 24 and 30 months in a sample of ethnically diverse families (n = 128) participating in a parenting intervention study. We also investigated interaction effects between mothers' and fathers' ESBs and between each parent's ESBs and child emotionality. We coded parents' ESBs to their toddlers' positive and negative emotions during no-toy play and a clean-up task.

Knowledge About Respiratory Syncytial Virus and Acceptance of Infant Monoclonal Antibody for RSV and RSV Vaccination During Pregnancy.

Background: Respiratory syncytial virus (RSV) is the leading cause of hospitalization among infants in the United States (US). RSV immunization, in the form of a monoclonal antibody (mAb) for infants and vaccines for pregnant people, may reduce infant RSV risk.

Methods: In April and May 2023, we surveyed adults with children in Oregon and Washington about the likelihood to accept infant mAb and maternal RSV vaccine and RSV awareness.

Three-unit CAD/CAM-manufactured lithium disilicate FDPs after an average observation period of 120 months.

Objective: In recent decades, CAD/CAM-fabricated lithium disilicate restorations have become popular and have been approved for fixed dental protheses (FDPs) up to the second premolar since 2013. This multicenter follow-up study collected long-term clinical data on three-unit anterior and premolar FDPs made of lithium disilicate to evaluate the material's suitability over >10 years.

Methods: Thirty-two patients received a total of 32 three-unit anterior or premolar monolithic lithium disilicate FDPs.

Electro-oxidative Deoxyfluorination of Arenes with NEt·3HF.

This report describes the design, development, and optimization of an electrochemical deoxyfluorination of arenes using a tetrafluoropyridine-derived leaving group. NEt·3HF serves as the fluoride source, and the reactions are conducted using either constant potential or constant current electrolysis in an undivided electrochemical cell. Mechanistic studies support a net oxidative pathway, in which initial single-electron oxidation generates a radical cation intermediate that is trapped by fluoride.

Genomic reanalysis of a pan-European rare-disease resource yields new diagnoses.

Genetic diagnosis of rare diseases requires accurate identification and interpretation of genomic variants. Clinical and molecular scientists from 37 expert centers across Europe created the Solve-Rare Diseases Consortium (Solve-RD) resource, encompassing clinical, pedigree and genomic rare-disease data (94.5% exomes, 5.

Background: Infections with fluconazole-resistant Candida parapsilosis have been increasing in Israeli hospitals with unclear implications for patient outcomes.

Objectives: To determine the frequency, mechanisms, molecular epidemiology, and outcomes of azole-resistant C. parapsilosis bloodstream infections in four hospitals in Israel.

Developmental transcriptomics in reveals the logic of a plasticity gene regulatory network.

Developmental plasticity enables the production of alternative phenotypes in response to different environmental conditions. While significant advances in understanding the ecological and evolutionary implications of plasticity have been made, understanding its genetic basis has lagged. However, a decade of genetic screens in the model nematode has culminated in 30 genes which affect mouth-form plasticity.

Interlayer Exciton-Phonon Coupling in MoSe/WSe Heterostructures.

Transition metal dichalcogenide heterostructures have garnered strong interest for their robust excitonic properties, mixed light-matter states such as exciton-polaritons, and tailored properties, vital for advanced device engineering. Two-dimensional heterostructures inherit their physics from monolayers with the addition of interlayer processes that have been particularly emphasized for their electronic and optical properties. Here, we demonstrate the interlayer coupling of the MoSe phonons to WSe excitons in a WSe/MoSe heterostructure using resonant Raman scattering.

Double Tips for In-Plane Polarized Near-Field Microscopy and Spectroscopy.

Near-field optical microscopy and spectroscopy provide high-resolution imaging below the diffraction limit, crucial in physics, chemistry, and biology for studying molecules, nanoparticles, and viruses. These techniques use a sharp metallic tip of an atomic force microscope (AFM) to enhance incoming and scattered light by excited near-fields at the tip apex, leading to high sensitivity and a spatial resolution of a few nanometers. However, this restricts the near-field orientation to out-of-plane polarization, limiting optical polarization choices.

Quantification of nisin concentration from fluorescence-based antimicrobial activity assay using Bayesian calibration.

Bacteriocins are ribosomally synthesized peptides with the innate ability to kill or inhibit growth of other bacteria. In recent years, bacteriocins have received increased interest, as their antimicrobial activity enhances food safety and shelf life by combatting pathogens such as Listeria monocytogenes. They also have application potential as an active pharmaceutical compound to combat multidrug-resistant pathogens.

Dielectric Screening inside Carbon Nanotubes.

Dielectric screening plays a vital role in determining physical properties at the nanoscale and affects our ability to detect and characterize nanomaterials using optical techniques. We study how dielectric screening changes electromagnetic fields and many-body effects in nanostructures encapsulated inside carbon nanotubes. First, we show that metallic outer walls reduce the scattering intensity of the inner tube by 2 orders of magnitude compared to that of air-suspended inner tubes, in line with our local field calculations.
