Predefined Time and Prespecified Precision for Bearing-Constrained AAV Swarm.

This article presents a bearing-based formation control method for autonomous aerial vehicle (AAV) swarms, allowing users to specify both convergence time and precision in advance. Unlike traditional distance-based methods, which rely on intricate distance measurements, our approach simplifies constraints using bearing information, reducing hardware and sensing requirements. It also eliminates the need to update control commands for each AAV, as formation reconfiguration can be achieved solely by adjusting the motion trajectory of formation leaders.

Dietary polysaccharides from dragon fruit pomace, a co-product of the fruit processing industry, exhibit therapeutic potential in high-fat diet-induced metabolic disorders.

The increasing prevalence of metabolic disorders, often associated with high-fat diets (HFD), highlights the need for new therapeutic approaches, especially from natural sources. Dragon fruit pomace, a by-product of the fruit processing industry, is rich in polysaccharides with potential health benefits. This study investigates the effects of dragon fruit pomace-derived polysaccharides (PDPS) in alleviating HFD-induced metabolic dysfunction.

Sensitivity of ophthalmologists, residents, and optometrists in identifying peripheral retinal tears on ultra-widefield imaging.

Objective: To compare the sensitivity of 3 groups of masked graders with varying levels of ophthalmic training to identify peripheral retinal breaks utilizing ultra-widefield orthogonal, directed peripheral steering, and auto-montaged images.

Design: Retrospective observational cohort study.

Participants: 155 patients from a single vitreoretinal specialist's practice.

Association of macular sensitivity with posterior staphyloma in highly myopic eyes: Aier-SERI high myopia adult cohort study.

Purpose: The purpose of this study was to determine the relationship between macular sensitivity (MS) and posterior staphyloma (PS) in highly myopic eyes.

Methods: This cross-sectional, observational study included 646 highly myopic eyes (spherical equivalent (SE) ≤-5.00D and the international meta-analysis for pathologic myopia classification grade of <2) from 362 participants.

Strategic variability in routing: Enhancing network performance in two-layer traffic systems.

We develop a model for two-layer traffic flow in which a batch of n_{o} packets are dispatched from the source at regular intervals. This scenario is applicable in various communication and transportation systems, such as TCP congestion control mechanisms and congestion management through traffic lights. We demonstrate that implementing stochastic switching between the shortest-path and greedy approaches in the routing strategy of packet transmission results in a significant reduction in the total transmission weight when n_{o} exceeds a certain threshold.
