Near‐Field Nanoimaging of Programmable Phase Transitions in Ga+‐Irradiated VO2
Advanced Optical Materials, EarlyView.Focused Ga+ ion irradiation locally reprograms the insulator‐to‐metal transition in VO2 thin films. Infrared and terahertz near‐field nanoimaging reveals that low irradiation doses localize the resistive‐switching filament within the defect region, while high doses suppress switching there and redirect the filament into pristine VO2.

A case of limit behaviour of vertex degrees in conditional configuration graphs
Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2017 We consider configuration graphs with N vertices. The degrees of the verticesare independent identically distributed random variables according to power-lawdistribution with positive parameter .

Origami‐Inspired Structural Design for Aquatic‐Terrestrial Amphibious Robots
Advanced Robotics Research, EarlyView.This work presents a lightweight amphibious origami robot actuated by a single shape memory alloy wire. A rigid foldable origami structure with displacement amplification enables efficient terrestrial crawling and aquatic swimming. The addition of fan‐shaped units allows controllable turning in both environments.

3D‐Printing Aided Rapid Prototyping of Pretensioned Tensegrity Structures for Robotic Applications
Advanced Robotics Research, EarlyView.Printing, injection molding, and assembly (PMA) is a method for rapid prototyping mesoscale, topologically complex, and tensioned tensegrity structures. In combination with PMA method, two mold design strategies: modular mold and compact channel layout, enable efficiency and scalability for tensegrity fabrication.

A Parameterized Algorithm for Bounded-Degree Vertex Deletion [PDF]
, 2016 The $d$-bounded-degree vertex deletion problem, to delete at most $k$ vertices in a given graph to make the maximum degree of the remaining graph at most $d$, finds applications in computational biology, social network analysis and some others. It can be regarded as a special case of the $(d+2)$-hitting set problem and generates the famous vertex cover

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 ...

Theta expansion of first massive vertex operator in pure spinor
Journal of High Energy Physics, 2018 We provide the covariant superspace equations that are sufficient to determine the complete θ expansion of the vertex operator of the open string massive states with (mass)2 = 1/α′ in pure spinor formalism of superstring theory.

On vertex-degree restricted paths in polyhedral graphs
Discrete Mathematics, 2000 Given two positive integers \( c, \delta \) and a connected planar graph \( H \), let \( \varphi (c,\delta;H) \) denote the minimum integer such that every \( c \)-connected graph \( G \) of minimum degree \( \geq \delta \) that contains a subgraph isomorphic to \( H \) contains also a subgraph \( H' \) isomorphic to \( H \) for which \( \text{deg}_G(x)

A Whole‐Head Finite Element Model for Electrical Neuromodulation via Visual Brain‐Machine Interfaces
Advanced Science, EarlyView.A multimodal, personalized head model is presented that integrates the entire visual pathway with surrounding tissues to simulate electrical stimulation of the optic nerve. In vivo validation in humans and goats, plus systematic component‐elimination analysis, demonstrates the high accuracy of the comprehensive model.
