Advanced Robotics Research, EarlyView.Visual teach‐and‐repeat (VTR) navigation allows robots to learn and follow routes without building a full metric map. We show that navigation accuracy for VTR can be improved by integrating a topological map with error‐drift correction based on stereo vision.

Minimal locating-paired-dominating sets in triangular and king grids
Kuwait Journal of Science, 2018 Let G = (V,E) be a finite or infinite graph. A set S ? V is paired-dominating if S induces a matching in G and S dominates all vertices of G. A set S ? V is locating if for any two distinct vertices u, v in V \ S, N(u) ? S 6= N(v) ?

Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract
Advanced Robotics Research, EarlyView.We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

Grip and Grasp: Lizard Claw Inspired Robotic Manipulators
Advanced Robotics Research, EarlyView.Our study identifies the most effective lizard claw shape for use as an end effector in a bioinspired robotic manipulator. By examining key geometric features and combining them into comparative indices, the Crotaphytus collaris claw is found to be the best fit.

Advanced Robotics Research, EarlyView.Intelligent Sky Guardians (InSkyGuard) is introduced as a four‐drone swarm that autonomously detects, tracks, and safely captures rogue drones using a coordinated net system. Computer vision and leader–follower control architecture enable synchronized enclosure, while integrated failsafes enhance system reliability. Validated through closed‐environment

Advanced Science, EarlyView.Cytoplasmic aggregation of TDP‐43 is a common pathological feature in amyotrophic lateral sclerosis, frontotemporal lobar degeneration, and Alzheimer's disease with TDP‐43 pathology. This study reports that wild‐type PDI slows down phase separation of TDP‐43 through direct interaction with TDP‐43.

Entorhinal cortex receptive fields are modulated by spatial attention, even without movement
eLife, 2018 Grid cells in the entorhinal cortex allow for the precise decoding of position in space. Along with potentially playing an important role in navigation, grid cells have recently been hypothesized to make a general contribution to mental operations.
