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

Small points on subvarieties of a torus [PDF]
, 2009 Let V be a subvariety of a torus defined over the algebraic numbers. We give a qualitative and quantitative description of the set of points of V of height bounded by invariants associated to any variety containing V .

Advanced Robotics Research, EarlyView.This review highlights recent advances in material extrusion 3D printing of self‐healing polymers, focusing on the interplay between material chemistry, rheology, hardware customization, and process optimization. Filament‐ and ink‐based extrusion strategies, multimaterial architectures, and postprocessing approaches are discussed for applications in ...

Дифференциальная геометрия многообразий фигур, 2018 The translation surface is the surface formed by the parallel transfer of the curve so that its point slides along another curve. We study the torus different from the classic torus, which is obtained by rotating the circle along the axis. We consider

Nonreciprocal Swarmalators With Reconfigurable and Controllable Formations for Robot Collectives
Advanced Robotics Research, EarlyView.Nonreciprocal swarmalator interactions are enabled through control barrier functions to transform self‐organizing robot collectives into reconfigurable, constraint‐aware systems. Complex two‐ and three‐dimensional shapes, continuous morphing, obstacle‐aware navigation, collective splitting, and object transport emerge from modulating agent‐level ...

Irreducible Quadrangulations of the Torus
Journal of Combinatorial Theory, Series B, 1996 A quadrangulation \(G\) of a closed surface \(S\) is a simple graph embedded in \(S\) all whose faces are quadrangles. A contraction at a pair of points \(\{b,d\}\) which lie in a common face \(f\) is a combinatorial operation that essentially removes the quadrangle \(f\) and ``glues'' together faces containing \(b\) or \(d\) (see precise definition in

Harnessing Phase Separation for the Development of High‐Performance Hydrogels
Advanced Science, EarlyView.ABSTRACT Hydrogels are indispensable for the development of next‐generation bioelectronics, soft robotics, and biomedical devices, where their mechanical properties determine performance and reliability. Among strategies to enhance hydrogel mechanics, phase separation enables controlled heterogeneity resulting in gel networks that are reinforced by ...
