Graphene‐Based Wearable Textile Triboelectric Nanogenerators and Biomechanical Sensors

Advanced Materials Technologies, EarlyView.
This study presents a wearable textile‐based triboelectric nanogenerator (T‐TENG) using sprayed graphene enhanced with a PVA adhesion layer. The graphene‐based electrode demonstrates high electrical conductivity and robustness to multiple bends. The fabricated T‐TENG provides stable and efficient output, with strong responsiveness to biomotion.

Higher Derivations Satisfying Certain Identities in Rings

Journal of Mathematics
Let n and m be fixed positive integers. In this paper, we establish some structural properties of prime rings equipped with higher derivations. Motivated by the works of Herstein and Bell-Daif, we characterize rings with higher derivations D=dii∈N ...

Constructions of Dense Lattices of Full Diversity

Trends in Computational and Applied Mathematics, 2020
A lattice construction using Z-submodules of rings of integers of number fields is presented. The construction yields rotated versions of the laminated lattices A_n for n = 2,3,4,5,6, which are the densest lattices in their respective dimensions.

Electromagnetic Wave Localization in One‐Dimensional Hyperuniform Disordered Structures

Advanced Optical Materials, EarlyView.
Stealthy hyperuniform disorder in one dimension exhibits strikingly different structural and photonic behavior compared with higher dimensions. By analysing spatial correlations and electromagnetic eigenstates, we show that short‐range pairing strongly shapes localization and transport regimes.

Codes Over Rings of Algebraic Integers

Journal of Communication and Information Systems, 1998
1 modulo 6 if d = -3.These alphabets are isomorphic to the field GF(p), and both will be denoted by A. Associated to any two elements of G F (p) , there is a distance, which is called Mannheim distance between the corresponding elements in A. Four classes of codes are proposed.One class is designed to correct one Mannbeim error, another to correct ...

Linear and Third‐Order Nonlinear Optical Response of Hafnium Disulfide

Advanced Optical Materials, EarlyView.
This study characterizes the linear and nonlinear optical response of HfS2 thin films. Ellipsometry identifies a high in‐plane refractive index (n>${\rm n}>$3) and wide transparency window. Third harmonic generation (THG) reveals a massive third‐order nonlinear susceptibility exceeding silicon and gallium phosphide.

Algorithmic search for integer Abelian roots of a polynomial with integer Abelian coefficients [PDF]

Известия Саратовского университета. Новая серия: Математика. Механика. Информатика
In this work, we consider the operations over Abelian integers of rank $n$. By definition, such numbers are elements of the complex field and have the form of polynomials with integer coefficients from the $n$th degree primitive root of 1.

Data‐Driven Bulldozer Blade Control for Autonomous Terrain Leveling

Advanced Robotics Research, EarlyView.
A simulation‐driven framework for autonomous bulldozer leveling is presented, combining high‐fidelity terramechanics simulation with a neural‐network‐based reduced‐order model. Gradient‐based optimization enables efficient, low‐level blade control that balances leveling quality and operation time.
