Optimal control of Newton-type problems of minimal resistance [PDF]
, 2006 We address Newton-type problems of minimal resistance from an optimal control perspective. It is proven that for Newton-type problems the Pontryagin maximum principle is a necessary and sufficient condition.

Thermally Robust Room‐Temperature Interlayer Excitons in a Hybrid van der Waals Heterostructure
Advanced Functional Materials, EarlyView.We report an optically active interlayer exciton in a hybrid van der Waals (PEA)2PbBr4/MoS2 heterostructure that remains thermally stable up to 400 K. The emission exhibits polarization anisotropy consistent with an out‐of‐plane optical transition‐dipole component and shows lifetime extension indicative of electron–hole separation.

Advanced Materials, EarlyView.Spin‐selective hot‐carrier transfer across CrSBr/WSe2/CrSBr interfaces couples the continuously tunable magnetic configuration of antiferromagnetic CrSBr to the valley degrees of freedom of monolayer WSe2, enabling giant nonequilibrium valley control and magnetic‐state‐dependent reversal of circularly polarized emission.

Newton methods for solving two classes of nonsmooth equations [PDF]
, 1997 summary:The paper is devoted to two systems of nonsmooth equations. One is the system of equations of max-type functions and the other is the system of equations of smooth compositions of max-type functions.

Advanced Materials Technologies, EarlyView.In this study, we developed a light–driven soft microgripper by 3D–printing a photo–crosslinkable, temperature–responsive hydrogel with embedded silver particles onto an optical fiber tip. The microgripper actuates via photothermal effects at cell culture temperature and can gently grasp spheroids without minimal damage, offering a compact, actuator ...

On the construction of minimisation methods of quasi-Newton type
Journal of Computational and Applied Mathematics, 1987 The paper investigates possibilities for the formulation of new quasi- Newton type methods. In doing so the so-called secant equation of the classical quasi-Newton algorithms is replaced by a more general equation. In this way it is possible to give a nonlinear approximation of the Newton equation, the solution of which corresponds to the Newton search

Red‐Light Tomographic Volumetric 3D Printing in Seconds for Fabrication of Colorless Structures
Advanced Materials Technologies, EarlyView.A custom red‐light‐responsive TVAM platform combines methylene blue, triethanolamine, and PEGDA to fabricate transparent crosslinked hydrogels. Light patterns are projected into a rotating resin container, where a sacrificial photoinitiator system enables rapid polymerization and colorless channel‐containing structures, utilizing low‐energy light for ...

Dynamic Fluorescence Modulation via Light‐Driven Competitive Protonation
Advanced Optical Materials, EarlyView.A two‐component molecular system demonstrates reversible, light‐driven fluorescence write–erase cycling and thermal imaging. Illumination of a merocyanine photoacid transfers a proton to a highly efficient fluorescent pyridinium dye, switching its emission color; thermal relaxation reverses the process in the dark.
