Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Functions of bounded variation and nonlocal functionals
有界 变差函数 非局部泛函
2023/11/29
In the past two decades, starting with the pioneering work of Bourgain, Brezis, and Mironescu, there has been widespread interest in characterizing Sobolev and BV (bounded variation) functions by mean...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：On strongly quasiconvex functions: existence results and proximal point algorithms
强准孔函数 存在结果 近端点算法
2023/5/4
The class of strongly quasiconvex functions was introduced in the famous paper of B.T. Polyak in 1966. It is the natural extension of the class of strongly convex functions, its applications emcompass...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Balanced Boolean Functions with Good Autocorrelation Spectra and Their Applications

棉花 YUC基因家族 生长素合成
2024/5/17
生长素在植物的正常生长发育中起着至关重要的作用。TAA/YUCCA基因家族编码色氨酸氨基转移酶（tryptophan aminotransferase），是生长素合成的关键酶。然而，棉花中YUCCA（YUC）基因家族尚未见报道。为了揭示YUC基因在棉花中的功能，我们系统地鉴定了五个棉种中的YUC基因家族，包括成员分析、特征描述、基因组内复制和共线关系。转录组学分析表明，GhYUCs参与了棉花的非生...
