Higher-order co-moments in asset pricing on the stock exchange in Brazil
GEPROS: Gestão da Produção, Operações e Sistemas, 2015 This study seeks to identify the behavior of systemic asymmetry (coskewness) and systemic kurtosis (cokurtosis) in asset pricing on the Brazilian stock exchange (in BM&F Bovespa).

Pinning Effects of Exchange and Magnetocrystalline Anisotropies on Skyrmion Lattice
Frontiers in Physics, 2021 Reorientation of skyrmion crystal (SkX) with respect to crystallographic axes is believed to be insensitive to anisotropies of fourth order in spin-orbit coupling, for which sixth order terms are considered for explanation.

Competing Spin Liquids and Hidden Spin-Nematic Order in Spin Ice with Frustrated Transverse Exchange
Physical Review X, 2017 Frustration in magnetic interactions can give rise to disordered ground states with subtle and beautiful properties. The spin ices Ho_{2}Ti_{2}O_{7} and Dy_{2}Ti_{2}O_{7} exemplify this phenomenon, displaying a classical spin-liquid state, with ...

Magnetic blue shift of Mott gaps enhanced by double exchange
Physical Review Research, 2021 A substantial energy gap of charge excitations induced by strong correlations is the characteristic feature of Mott insulators. We study how the Mott gap is affected by long-range antiferromagnetic order. Our key finding is that the Mott gap is increased

FEBS Letters, EarlyView.Metabolic dysfunction‐associated steatotic liver disease (MASLD) affects nearly one‐third of the global population and poses a significant risk of progression to cirrhosis or liver cancer. Here, we discuss the roles of hepatic dendritic cell subtypes in MASLD, highlighting their distinct contributions to disease initiation and progression, and their ...

FEBS Letters, EarlyView.The mitochondrial outer membrane iron–sulphur ([Fe‐S]) protein mitoNEET is a target of the type‐2 diabetes drug pioglitazone. Its unknown molecular function is linked to respiratory complex activity and mitochondrial function. We discovered that O2 protects the mitoNEET [2Fe‐2S] cluster against NO oxidation and desensitization towards reduction by H2S.

Exchange interaction between the triplet exciton and the localized spin in copper-phthalocyanine [PDF]
J. Chem. Phys. 140, 224301 (2014), 2014 Triplet excitonic state in the organic molecule may arise from a singlet excitation and the following inter-system crossing. Especially for a spin-bearing molecule, an exchange interaction between the triplet exciton and the original spin on the molecule can be expected.

Social Exchange and Micro Social Order [PDF]
American Sociological Review, 2008 This study uses an affect theory of social exchange (Lawler 2001) to investigate how and when network structures generate “micro social orders.” Micro social order entails recurrent interactions, emotional reactions, perceptions of a group, and affective sentiments.
