Exploring dentists’ perceptions, practices and potential stigma surrounding severe dental caries in children: A qualitative study

Abstract Background : Despite recommendations emphasizing individualized prevention and patient-centered communication, studies show that preventive care is often under-delivered in routine dental practice. Parents are sometimes identified by dentists as a major barrier to caries...

Spatially Resolved Physical Properties of Young Star Clusters and Star-forming Clumps in the Brightest z > 6 Galaxy, the Strongly Lensed Cosmic Spear at z = 6.2

Abstract We present a spatially resolved analysis of stellar populations in the brightest z > 6 galaxy known to date (AB mag 23), the strongly lensed MACS0308−zD1 (dubbed the “Cosmic Spear”) at z spec = 6.2. New JWST NIRCam imaging and high-resolution NIRSpec integral field unit...

Optimising toll prices and speed limits for minimising emissions in Zealand, Denmark, using a dynamic multi-region MFD SUE traffic model

Reducing emissions from road traffic is important for public health and the environment. One way of reducing emissions is electrifying the vehicle fleet. Full electrification, however, will take many years due to constraints on the production of electric vehicles to meet demand....

Direct imaging elucidates ionic memory in two-dimensional nanochannels

Abstract Nanofluidic memristors promise brain-inspired information processing with ions, yet their microscopic origin remains debated. So far, ionic memory has been attributed to ion-specific interactions, dynamic wetting, chemical reactions or mechanical deformations, yet typica...

High Lithium Bioaccumulation and Depuration Rates in Marine Mussels ( Mytilus edulis ): An Isotopic Perspective

Abstract The growing demand for lithium (Li), driven by its use in rechargeable batteries and energy storage technologies, raises concerns about its environmental impact, especially in coastal ecosystems, which serve as receptacles for many pollutants. This study quantifies the r...

The petal identity gene PhDEF has a major binding and regulatory action in the epidermis

ABSTRACT In flowering plants, floral organ identity is specified by the combinatorial action of homeotic genes. While the role of these genes in the early specification of organ identity is well established, their late function throughout floral organ development and in specific...

Osteocalcin and impaired cerebral resting-state functional connectivity in postmenopausal osteoporosis: a pilot case-control study

PURPOSE: Postmenopausal osteoporosis and circulating osteocalcin have been suggested to influence brain function. Objectives aim to explore associations between brain network resting-state functional magnetic resonance imaging (fMRI) connectivity, bone status, and circulating ost...

Revisiting quantum effects on dislocation glide in bcc metals from DFT calculations and machine-learning potentials

Quantum zero-point effects have been long proposed to explain a well-known discrepancy between the low-temperature flow stresses of body-centered cubic metals and corresponding atomistic models of plastic flow. Previous investigations on quantum effects relied on empirical intera...

High-power tunable laser operation of Ho:YScO 3 crystal at 2.1 µm

We report the Czochralski growth, spectroscopic characterization, and laser performance at 2.1 µm of a Ho:YScO 3 mixed sesquioxide crystal with a doping concentration of 0.4 at.%. Spectroscopic evaluation was performed based on room-temperature absorption and fluorescence measure...

Strong Coupling in Bulk Nanoplasmonic Nanoplatelet Perovskite Scintillators

ABSTRACT Control of light emission underpins photonics and radiation detection. Strong coupling between excitons and confined electromagnetic modes forms light–matter states known as polaritons, enabling emission control. In scintillators, such effects have been investigated main...
