C16 Phase High Entropy Borides With High Magnetic Anisotropy
Advanced Materials, EarlyView.Rare‐earth‐free C16‐phase high entropy boride thin films exhibit enhanced magnetic anisotropy with coercivities surpassing their binary and ternary counterparts. Combinatorial synthesis of (Fe‐Co‐Ni‐Mn)2B films combined with density functional theory enables mapping of the magnetic properties across the composition space, revealing high entropy ...

Tropical Fock–Goncharov coordinates for $\mathrm {SL}_3$ -webs on surfaces I: construction
Forum of Mathematics, SigmaFor a finite-type surface $\mathfrak {S}$ , we study a preferred basis for the commutative algebra $\mathbb {C}[\mathscr {R}_{\mathrm {SL}_3(\mathbb {C})}(\mathfrak {S})]$ of regular functions on the $\mathrm {SL}_3(\mathbb {C ...

Asynchronous Coordination of Distributed Mixed-Integer Linear Subsystems via Surrogate Lagrangian Relaxation [PDF]
, 2020 With the emergence of Internet of Things that allows communications and local computations, and with the vision of Industry 4.0, a foreseeable transition is from centralized system planning and operation toward decentralization with interacting components and subsystems, e.g., self-optimizing factories. In this paper, a new “price-based” decomposition

The Possibility of New Complex Magnet Materials
Advanced Materials, EarlyView.The quest for stronger magnets enters a new era. With the developments of AI‐driven materials discovery, computational prediction of magnetic properties, and autonomous laboratories, researchers can now explore millions of untested structures. Discovery of next‐generation ultra‐powerful magnets – critical for electric vehicles, renewable energy, and ...

Electric‐Current‐Assisted Nucleation of Zero‐Field Hopfion Rings
Advanced Materials, EarlyView.This work reports a novel and efficient nucleation protocol for 3D localized topological magnetic solitons‐hopfion rings in chiral magnets using pulsed electric currents. By using Lorentz transmission electron microscopy and topological analysis, we report characteristic features and extraordinary stability of hopfion rings in zero or inverted external

The Geometric Index of the Wheel, Wn
Davao Research Journal, 1998 The geometric index of a graph G is defined as the smallest non-negative integer n such that a graph G is a unit graph in r. Graphs considered are finite, undirected, without loops nor multiple edges.

Continuum Mechanics Modeling of Flexible Spring Joints in Surgical Robots
Advanced Robotics Research, EarlyView.A new mechanical model of a tendon‐actuated helical extension spring joint in surgical robots is built using Cosserat rod theory. The model can implicitly handle the unknown contacts between adjacent coils and numerically predict spring shapes from straight to significantly bent under actuation forces.
