Decoding Carbon Dot Purity by Nuclear Magnetic Resonance. [PDF]

Angew Chem Int Ed Engl
NMR spectroscopy tracks the removal of molecular and oligomeric impurities in carbon dots, enabling a (semi)quantitative evaluation of their purity through integrated peak analysis. ABSTRACT Carbon dots (CDs) have attracted increasing attention in recent years and have been widely explored in many fields.

Long-lasting remodeling of astrocytes in an Scna1^+/- mouse model of Dravet syndrome. [PDF]

Epilepsia
Abstract Objective Dravet syndrome (DS) is a prototypical developmental and epileptic encephalopathy caused by mutations in the SCN1A gene, leading to loss of function of the voltage‐gated sodium channel Naᵥ1.1. The latter causes early onset drug‐resistant seizures and enduring cognitive and behavioral deficits.

Testing and Simulation of Multilayer Polyvinylidene Fluoride‐Based Piezoelectric Energy Harvester Devices

Advanced Materials Technologies, EarlyView.
The study considers the use of polymer/dielectric‐based multilayers piezoelectric Energy Harvesters (EH) to produce an output voltage and current, by exploiting the mechanical energy provided by human organs movements. In particular, the heart motion is considered from the kinematic viewpoint, and a multiphysics theoretical model is developed to assess

THE EFFECT OF UNDERWATER IMAGERY RADIOMETRY ON 3D RECONSTRUCTION AND ORTHOIMAGERY [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
Abstract. The work presented in this paper investigates the effect of the radiometry of the underwater imagery on automating the 3D reconstruction and the produced orthoimagery. Main aim is to investigate whether pre-processing of the underwater imagery improves the 3D reconstruction using automated SfM - MVS software or not.

Magnetoencephalographic source imaging improves localization of the epileptogenic zone in multimodal imaging evaluation

Epilepsia, EarlyView.
Abstract Objective To assess the added diagnostic value of magnetoencephalographic source imaging (MSI) beyond conventional magnetic resonance imaging (MRI) and fluorodeoxyglucose–positron emission tomography (FDG‐PET) in localizing the epileptogenic zone, with stereo‐electroencephalography (SEEG) and surgical resection serving as reference standards ...

Deep Learning‐Based Dynamic Segmentation of the Left Atrium in 4D Flow MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To design a deep learning pipeline for automated, time‐resolved segmentation of the left atrium (LA) from 4D flow MRI data. Methods We studied 100 individuals including 65 patients with atrial fibrillation (AF) and 35 healthy subjects (HS) resulting in 2530 4D flow MRI time‐volumes acquired in different centers and scanners.

The morphological affinities of the fossil cranium from Kabua, Kenya Affinités morphologiques du crâne fossile de Kabua (Kenya)

Journal of the Royal Anthropological Institute, EarlyView.
Our current understanding of the origins of Homo sapiens is limited, in part, by the fragmented fossil record from Late Pleistocene and early Holocene Africa. Here, we re‐examine the Kabua 1 cranium, an enigmatic and little‐studied Kenyan fossil discovered in the 1950s. We compare virtual reconstructions created previously by our team with a wide range

A novel all‐in‐one dynamic wrinkle evaluation system: Development, validation and application in cosmetic industries

International Journal of Cosmetic Science, EarlyView.
Photo grading of dynamic lines in the dynamic line repeatability validation study. Abstract Objective This study aimed to develop and validate a novel, integrated dynamic wrinkle assessment system based on standardized, real‐time and multi‐angle facial images and video recordings, and to explore its potential application in evaluating the anti‐wrinkle ...

Improvements in the Visualization of Stereoscopic 3D Imagery [PDF]

3D Research, 2015
A pleasant visualization of stereoscopic imagery must take into account factors that may produce eye strain and fatigue. Fortunately, our binocular vision system has embedded mechanisms to perceive depth for extended periods of time without producing eye fatigue; however, stereoscopic imagery may still induce visual discomfort in certain displaying ...

Effects of repeated exposure to ozonated water on hair fibre structure and integrity: Part I

International Journal of Cosmetic Science, EarlyView.
Repeated exposure to ozonated water caused cumulative oxidative changes in hair, altering structural integrity, thermal behaviour and mechanical properties. The findings reveal a distinct ozone‐induced damage profile that progresses beyond the cuticle, challenging claims of hair‐revitalizing benefits. Abstract Objective Ozone has recently been marketed
