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

The Gauss curvature flow : Regularity and Asymptotic Behavior
, 2017 This thesis contains the author's results on the evolution of convex hypersurfaces by positive powers of the Gauss curvature. We first establish interior estimates for strictly convex solutions by deriving lower bounds for the principal curvatures and ...

Advanced Science, EarlyView.An atomically precise platform was developed for investigating single‐molecule charge transport. This innovative platform enables the creation of highly uniform molecular devices using ruthenium‐based molecules. It reveals a significant enhancement in molecular conductance due to the metallic ruthenium center and a unique barrier‐lowering effect during

Advanced Science, EarlyView.A reconfigurable physical unclonable function is developed using CMOS‐integrated SOT‐MRAM chips, leveraging a dual‐pulse strategy and offering enhanced environmental robustness. A temperature‐compensation effect arising from the CMOS transistor and SOT‐MTJ is revealed and established as a key prerequisite for thermal resilience.

Rotational Hypersurfaces with Constant Gauss-Kronecker Curvature
Chinese Annals of Mathematics, Series B, 2022 We study rotational hypersurfaces with constant Gauss-Kronecker curvature. We solve the ODE for the generating curves of such hypersurfaces and analyze several geometric properties of such hypersurfaces. In particular, we discover a class of non-compact rotational hypersurfaces with constant and negative Gauss-Kronecker curvature and finite volume ...

Tunable High‐Performance Metamaterial Filters Based on Novel SRR Architectures
Advanced Science, EarlyView.Based on two novel SRR configurations and two independent SRR integration approaches, four tunable bandpass metamaterial filters were fabricated with an ultra‐thin ceramic substrate. Among them, SM‐2 achieves over 97% electromagnetic wave transmittance, with a minimal 1.15% deviation in its resonant frequency prediction, making them promising ...

Binormal Motion of Curves with Constant Torsion in 3-Spaces
Advances in Mathematical Physics, 2017 We study curve motion by the binormal flow with curvature and torsion depending velocity and sweeping out immersed surfaces. Using the Gauss-Codazzi equations, we obtain filaments evolving with constant torsion which arise from extremal curves of ...

Scalar field collapse in Gauss–Bonnet gravity
European Physical Journal C: Particles and Fields, 2018 We consider a “scalar-Einstein–Gauss–Bonnet” theory in four dimension, where the scalar field couples non-minimally with the Gauss–Bonnet (GB) term. This coupling with the scalar field ensures the non-topological character of the GB term.
