Exceptional Second Harmonic Generation in Ultraviolet Nonlinear Optical Oxyfluoroniobate Crystals via Structural Fingerprint Optimization of Polar Chains

open access: yesAngewandte Chemie, EarlyView.
A structural fingerprint optimization strategy is proposed for the 1[TMOF4]∞ chain‐based compounds, aimed at modifying the geometric features of functional chains to maximize the optical nonlinearity. In the ultraviolet (UV) nonlinear optical (NLO) crystal (H3O)(Biu)2(NbOF4), the structural fingerprints of the functional chains satisfy the ideal ...

A Fuzzy Risk Assessment Approach Based on Z‐Numbers for Enhancing Safety and Human‐Robot Collaboration in Automotive Sector

open access: yesAdvanced Intelligent Systems, EarlyView.
A novel risk assessment approach that integrates the fuzzy set theory and Z‐numbers with multicriteria decision‐making techniques (Delphi, decision‐making trial and evaluation laboratory, analytic network process, and VIseKriterijumska Optimizacija I Kompromisno Resenje) to manage uncertainty and prioritize human–robot collaboration risks. A real‐world

A Soft Pneumatic Exosuit to Assist Pronosupination in Individuals with Spinal Cord Injury

open access: yesAdvanced Intelligent Systems, EarlyView.
A lightweight (30 g) textile‐based pneumatic exosuit assists forearm pronosupination in individuals with cervical spinal cord injury. The soft robot enhances forearm range of motion and reduces muscle effort without hindering hand function. Tested in 10 patients during an interactive exergame, it improves motor performance and demonstrates promise for ...

Diagonal Peg Solitaire

open access: yes, 2007
We study the classical game of peg solitaire when diagonal jumps are allowed. We prove that on many boards, one can begin from a full board with one peg missing, and finish with one peg anywhere on the board.
