Distributional Energy-Momentum Densities of Schwarzschild Space-Time [PDF]
, 1997 For Schwarzschild space-time, distributional expressions of energy-momentum densities and of scalar concomitants of the curvature tensors are examined for a class of coordinate systems which includes those of the Schwarzschild and of Kerr-Schild types as

All Stable Characteristic Classes of Homological Vector Fields
, 2010 An odd vector field $Q$ on a supermanifold $M$ is called homological, if $Q^2=0$. The operator of Lie derivative $L_Q$ makes the algebra of smooth tensor fields on $M$ into a differential tensor algebra.

Journal of Statistical Theory and Applications (JSTA), 2019 We introduce the generalized Farlie–Gumbel–Morgenstern (FGM) type bivariate-generalized exponential distribution. Some distributional properties of concomitants of order statistics as well as record values for this family are studied.

Sigma models with off-shell N=(4,4) supersymmetry and noncommuting complex structures
, 2010 We describe the conditions for extra supersymmetry in N=(2,2) supersymmetric nonlinear sigma models written in terms of semichiral superfields. We find that some of these models have additional off-shell supersymmetry.

核桃油组分及其在氧化过程中的变化研究进展Research progress on components of walnut oil and their changes during oxidation
Zhongguo youzhi, 2023 旨在为核桃油氧化机制和抗氧化研究提供参考，综述了核桃油中脂肪酸、甘油三酯、主要微量伴随物、挥发性成分及其在核桃油氧化过程中的变化情况。核桃油氧化除了受到外界因素如温度、光照和包装等的影响，与其本身组分关系密切，如脂肪酸组成、甘油三酯组分和内源性微量伴随物，可通过品种选育、优化加工工艺、添加活性成分、改进包装形式等方式来延缓核桃油的氧化。In order to provide reference for the study of walnut oil oxidation mechanism and ...
