AI Article Synopsis
Article Abstract
An external cavity diode laser is demonstrated using a Bragg grating written into a novel integrated optical fiber platform as the external cavity. The cavity is fabricated using flame-hydrolysis deposition to bond a photosensitive fiber to a silica-on-silicon wafer, and a grating written using direct UV-writing. The laser operates on a single mode at the acetylene P13 line (1532.83 nm) with 9 mW output power. The noise properties of the laser are characterized demonstrating low linewidth operation (< 14 kHz) and superior relative intensity noise characteristics when compared to a commercial tunable external cavity diode laser.

Mechanical behavior of external root resorption cavities restored with different materials: a 3D-FEA study.
BMC Oral Health

Faculty of Dentistry, Department of Endodontics, Ondokuz Mayis University, Samsun, Kurupelit, 55139, Turkey.
Background: The aim was to evaluate the stresses in teeth, with external root resorption (ERR) restored with different materials using finite element analysis (FEA).
Methods: In this study, a Micro-CT scan was conducted on a prepared maxillary central tooth. DICOM-compatible images obtained from the sections were converted into stereolithography format using Ctan software.

Introduction Supervised toothbrushing programmes (STPs) in nurseries and schools are effective at reducing inequalities in caries when targeted to areas of dental disease. Recent changes to government education and health policy have increased interest in STPs in England. This study aimed to establish the current level of provision of STPs in England, describe changes over time, understand associations with predictor variables, and summarise key barriers and facilitators to their implementation.

Shark skin features superhydrophilic and riblet-textured denticles that provide drag reduction, antifouling, and mechanical protection. The artificial riblet structures exhibit drag reduction capabilities in turbulent flow. However, the effects of the surface wettability of shark denticles and the cavity region underneath the denticle crown on drag reduction remain insufficiently explored.

Controlling reaction outcomes through external influences is a central goal in chemistry. Vibrational coupling between molecular vibrations and cavity modes is rapidly emerging as a distinct strategy compared with conventional thermochemical and photochemical methods; however, insight into the fundamental mechanisms remains limited. Here we investigate how vibrational weak and strong coupling in plasmonic nanocavities modifies the thermal dehydration of copper sulfate pentahydrate.

Obstetrics and Gynecology Unit, IRCCS Istituto Giannina Gaslini, Genoa, Italy.
Background: Vaginal delivery in twins is feasible but challenging. Successful vaginal delivery of a non-vertex second twin depends on knowledge of specific obstetrical maneuvers. Skill acquisition at the patient's bedside is difficult, making simulation training an integral part of obstetrics and gynecology residency programs.
