Systematical characterization of YUCCA gene family in five cotton species, and potential functions of YUCCA22 gene in drought resistance of cotton
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...
Very-long-chain ω-3 fatty acid supplements and adipose tissue functions: a randomized controlled trial
EPA DHA macrophage lipolysis inflammation insulin resistance
2018/11/14
Background: Increased omega-3 (n–3) fatty acid consumption is reported to benefit patients with metabolic syndrome, possibly due to improved adipose tissue function.
Executive functions and the ω-6-to-ω-3 fatty acid ratio: a cross-sectional study
fatty acids executive functions middle childhood CANTAB Electric Maze Task
2018/11/12
Background: The ω-6 (n–6) to ω-3 (n–3) fatty acid (FA) ratio (n–6:n–3 ratio) was previously shown to be a predictor of executive function performance in children aged 7–9 y.
Development of a Novel, Anti-idiotypic Monoclonal Anti-prolactin Antibody That Mimics the Physiological Functions of Prolactin
Prolactin Anti-idotypic Antibody Signal Transduction
2016/5/20
In this work, we prepared a panel of monoclonal anti-idiotypic antibodies to ovine prolactin (oPRL) by the hybridoma technique. Among these antibodies, one anti-idotypic antibody (designated B7) was c...
ZETA FUNCTIONS, GROTHENDIECK GROUPS, AND THE WITT RING
ZETA FUNCTIONS GROTHENDIECK GROUPS
2015/12/10
After preliminary definitions and a review (in the first section) of the basic structures (such as
Frobenius Fm and Verschiebung Vm) of the Witt ring W(R) of a ring R, we present our main...
Beginning with the conjecture of Artin and Tate in 1966, there has been a series of
successively more general conjectures expressing the special values of the zeta function
of an algebraic variety o...

For each ˉeld k, we deˉne a category of rationally decomposed mixed
motives with Z-coe±cients. When k is ˉnite, we show that the category is Tannakian, and we prove formulas relating the behaviour of...
A review of nonparametric attenuation functions computed for different regions of Italy
Seismic attenuation S waves non-parametric inversio acceleration spectra
2015/10/8
We used a set of previously published nonparametric attenuation functions to calculate average functions for the Italian region. These nonparametric functions describe the spectral amplitude decay of ...

SINGULARITIES OF ADMISSIBLE NORMAL FUNCTIONS (WITH AN APPENDIX BY NAJMUDDIN FAKHRUDDIN)
NORMAL FUNCTIONS NAJMUDDIN FAKHRUDDIN
2015/9/29
In a recent paper, M. Green and P. Griths used R. Thomas’ work on nodal
hypersurfaces to sketch a proof of the equivalence of the Hodge conjecture and the existence of certain singular admissible no...
ZERO LOCI OF ADMISSIBLE NORMAL FUNCTIONS WITH TORSION SINGULARITIES
NORMAL FUNCTIONS TORSION SINGULARITIES
2015/9/29
We show that the zero locus of a normal function on a smooth
complex algebraic variety S is algebraic provided that the normal function extends to a admissible normal function on a smooth compacti...
This paper addresses the natural question: “How should frames be compared?” We answer this question by quantifying the overcompleteness of all frames with the same index set. We introduce the concept ...

THE STABLE BERNSTEIN CENTER AND TEST FUNCTIONS FOR SHIMURA VARIETIES

2015/9/29
We elaborate the theory of the stable Bernstein center of a p-adic group G,
and apply it to state a general conjecture on test functions for Shimura varieties due to
the author and R. Kottwitz. This...
