Lipschitz continuously smoothing accelerated proximal gradient method

This paper presents smoothing proximal gradient methods using smooth approximation that is Lipschitz continuous with respect to a smoothing parameter in a non-differentiable term in an objective function. Furthermore, an accelerated proximal gradient method exploiting the strong...

Helicity‐Dependent All‐Optical Switching in Bi,Ga‐Substituted Rare‐Earth Iron Garnet Films Driven by Orbital Magnetic Moment

ABSTRACT All‐optical magnetization switching (AOS) is a promising phenomenon for applications such as high‐speed optical modulation technologies, as it enables magnetization switching using only ultrashort laser pulses. AOS induced by circularly polarized light is demonstrated in...

Charge-Neutral N–H···Br as a Hydrogen-Bond Family for the Construction of Hydrogen-Bonded Organic Frameworks

Abstract The design, synthesis, and application of porous molecular crystals constructed using intermolecular hydrogen bonds (hydrogen-bonded organic frameworks; HOFs) have attracted significant attention due to the potential flexibility and solution processability of HOFs, which...

Type-II-like ultrafast demagnetization behavior in NiCo2O4 thin films

Rare-earth-free ferrimagnetic oxides are emerging as attractive platforms for investigating ultrafast spin dynamics. Here, we study the photoinduced magnetization dynamics of epitaxial NiCo2O4 (NCO) thin films by the time-resolved magneto-optical Faraday effect using two independ...

Difference betweenConduction Band Minimum and Flat-BandPotential in Mott–Schottky Analysis of Anatase TiO2

Abstract Mott–Schottky analysis is widely used to estimate the band structures of semiconductors, including anatase TiO2, a representative photocatalyst. However, the conduction band minimum (CBM) derived from the flat-band potential (Vfb) in Mott–Schottky analysis often differs...

Aldehyde dehydrogenases for oligo-isoprene aldehyde oxidation in Rhodococcus sp. RDE2

Abstract The microbial degradation of natural rubber (NR), which is mainly composed of cis-1,4-polyisoprene, is a promising sustainable strategy for rubber waste treatment. In rubber-degrading actinomycetes, the polymer is cleaved by the latex-clearing protein (Lcp) into oligo-is...
