Rectification of Bowl-Shape Deformation of Tidal Flat DEM derived from UAV Imaging

open access: yesSensors, 2020
It is necessary to periodically obtain topographic maps of the geographical and environmental characteristics of tidal flats to systemically manage and monitor them.

Phosphoinositides and inositol phosphates as molecular glues

open access: yesFEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

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

open access: yesПроблеми 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 ...

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

open access: yesNeural 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 ...

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

open access: yesFEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

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

open access: yesRemote 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.

Pedestrian detection in uncontrolled environments using stereo and biometric information [PDF]

open access: yes, 2006
A method for pedestrian detection from challenging real world outdoor scenes is presented in this paper. This technique is able to extract multiple pedestrians, of varying orientations and appearances, from a scene even when faced with large and multiple
