Radiation Shielding Performance of B4C‐Reinforced Ultra‐High Molecular Weight Polyethylene Composites Against Low‐Energy X‐Rays: Experimental and Computational Analysis

Polymer Composites, EarlyView.
Radiation shielding behavior of B4C‐reinforced UHMWPE composites. ABSTRACT The present study investigates the radiation shielding performance of ultra‐high molecular weight polyethylene (UHMWPE) composites reinforced with varying boron carbide (B4C) contents against low‐energy X‐rays through combined experimental and computational approaches.

A Müller Glia-Retinal Pigment Epithelium Apical Network Surrounding Cone Outer Segments in Fish and Mouse. [PDF]

Glia
Müller glia and the retinal pigment epithelium interact around cone outer segment in the subretinal space of both zebrafish and mouse. The contacts are established early during development but subsequent to outer segment emergence. ABSTRACT Homeostasis of the vertebrate retina critically depends on two non‐neuronal cell populations, Müller glia and the

Drift‐Corrected Monocular VIO and Perception‐Aware Planning for Autonomous Drone Racing

Journal of Field Robotics, EarlyView.
ABSTRACT The Abu Dhabi Autonomous Racing League (A2RL) x Drone Champions League (DCL) competition requires teams to perform high‐speed autonomous drone racing using only a single camera and a low‐quality inertial measurement unit—a minimal sensor set that mirrors expert human drone racing pilots.

Low‐contrast visual acuity versus low‐luminance visual acuity in choroideremia

Clinical and Experimental Optometry, EarlyView., 2020
Clinical relevance Choroideremia is a progressive X‐linked inherited rod‐cone dystrophy. Patients present with nyctalopia and progressive visual field loss, but visual acuity remains well preserved early on. This study showed that low‐luminance visual acuity may be a useful clinical outcome measure during earlier disease stages.

Advances in deep‐tissue fluorescence imaging through optical clearing: A review

VIEW, EarlyView.
Optical clearing refers to techniques that are used to improve the optical transparency of biological tissues. Optical clearing enables imaging of deeper lying tissues as well as 3D volumetric imaging of whole organs. This review examines reports on the integration of optical clearing with advanced fluorescence imaging techniques, with particular ...

Gut microbiota dysbiosis in the inflammatory pathogenesis of diabetic retinopathy

VIEW, EarlyView.
This graphical abstract illustrates how gut dysbiosis drives diabetic retinopathy through the gut‐retina axis, a process unfolding in three interconnected stages. First, in the gut, a decrease in beneficial bacteria and an increase in pro‐inflammatory taxa compromise the intestinal barrier, causing a “leaky gut” that allows LPS to translocate into the ...
