Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

ALGORITHM FOR DIGITAL CONTROL OF THE ANTENNA OF THE GROUND CONTROL POINT OF THE UNMANNED AVIATION COMPLEX

Проблеми створення, випробування, застосування та експлуатації складних інформаційних систем, 2019
Every year, unmanned aircraft systems are increasingly used in both the civilian and military spheres. Stable communication with an unmanned aerial vehicle is provided by high-precision pointing of the antenna of the ground control point. In the automatic tracking mode of an unmanned aerial vehicle, the antenna guidance is carried out by the automatic ...

Automating Ground Control Point Detection in Drone Imagery: From Computer Vision to Deep Learning

Remote Sensing
Drone-based photogrammetry typically requires the task of georeferencing aerial images by detecting the center of Ground Control Points (GCPs) placed in the field. Since this is a very labor-intensive task, it could benefit greatly from automation.

THE USE OF UNMANNED AERIAL VEHICLES FOR CADASTRAL MAPPING IN GHANA-ASSESSING THE EFFECT OF VARYING SENSOR TYPES, FLYING HEIGHT, IMAGE OVERLAP AND GROUND CONTROL POINT DENSITY

African Journal on Land Policy and Geospatial Sciences, 2022
Context and background In Ghana the predominant method for performing cadastral surveys is through the use of Global Navigation Satellite Systems (GNSS) static surveys and to a lesser extent Total Stations.

Ground-based telescope pointing and tracking optimization using a neural controller

Neural Networks, 2003
Neural network models (NN) have emerged as important components for applications of adaptive control theories. Their basic generalization capability, based on acquired knowledge, together with execution rapidity and correlation ability between input stimula, are basic attributes to consider NN as an extremely powerful tool for on-line control of ...

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Research on Time Series Monitoring of Surface Deformation in Tongliao Urban Area Based on SBAS-PS-DS-InSAR

Sensors
As urban economies flourish and populations become increasingly concentrated, urban surface deformation has emerged as a critical factor in city planning that cannot be overlooked. Surface deformation in urban areas can lead to deformations in structural

Discerning protein pools by selective staining with self‐labeling tags

FEBS Letters, EarlyView.
Cell surface proteins have an intra‐ and extracellular pool. Combining genetic fusion to self‐labeling tags that can be addressed with small molecule fluorophores allows separating these pools. We highlight recent developments and techniques for state‐of‐the‐art interrogation of cell surface proteins in the complex tissue setting.

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

FEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...
