Non-stationary Magnetic Microstructures in Stellar Thin Accretion Discs
, 2013 We examine the morphology of magnetic structures in thin plasma accretion discs, generalizing a stationary ideal MHD model to the time-dependent visco-resistive case.

Magnetic Force Microscopy Signatures of Higher‐Order Skyrmions and Antiskyrmions
Advanced Functional Materials, EarlyView.Magnetic force microscopy operated under vacuum conditions enables the qualitative identification of higher‐order skyrmions and antiskyrmions in Co/Ni multilayers at room temperature. Distinct stray‐field contrast signatures arise from vertical Bloch lines and complex domain‐wall configurations.

Generalization of f-Graphs and Their Algebraic Aspects
Journal of Mathematics, 2023 The notion of f-graphs and f-ideals are relatively new and have been studied in many papers. In this paper, we have generalized the idea of f-graphs and f-ideals to quasi f-graphs and quasi f-ideals, respectively. We have characterized all quasi f-graphs

2D Magnetic and Topological Quantum Materials and Devices for Ultralow Power Spintronics
Advanced Functional Materials, EarlyView.2D magnets and topological quantum materials enable ultralow‐power spintronics by combining robust magnetic order with symmetry‐protected, Berry‐curvature‐driven transport. Fundamentals of 2D anisotropy and spin‐orbit‐coupling induced band inversion are linked to scalable growth and vdW stacking.

On (m, n)-ideals and (m, n)-regular ordered semigroups [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2016 Let m, n be non-negative integers. A subsemigroup A of an ordered semigroup (S, , is called an (m, n)-ideal of S if (i) Am SAn A, and (ii) if x A, y S such that y x, then y A. In this paper, necessary and sufficient conditions for every (

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges
Advanced Functional Materials, EarlyView.Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

Countable Ideals in a Semi-Lattice of the De Enumeration Degrees
Моделирование и анализ информационных систем, 2015 In the article we have proved that any countable ideal in the semi-lattice of the De is the intersection of two principal ideals generated by quasi-minimal covers for this ideal.

Optimum design for quasi-ideal beam transducer.
The Journal of the Marine Acoustics Society of Japan, 1990 Recent advancement in electronics technology is helping accelerate the development of new generation of underwater acoustic equipment. The transducer, a sensor of the underwater acoustic equipment, generally has directivity in its beam pattern. Many papers on the improvement of the directivity have so far been presented.

Advanced Functional Materials, EarlyView.Cephalopod‐inspired photonic microparticles with dynamic structural coloration are fabricated via confined self‐assembly of linear block copolymers into ellipsoids containing stacked lamellae. Embedded superparamagnetic nanoparticles enable rapid magnetic alignment, restoring vivid, angle‐dependent color.
