生命活动往往是多种细胞协同参与、时空高度调控的复杂过程。因此，对活体中的特定细胞及特定生命分子进行原位的标记、操纵及分析，是研究现代生物学问题的关键途径。基因工程方法（如融合荧光蛋白标签）能够在活细胞中提供精准的标记信号，但其应用范围受限，不适用于一些难以转染的样品（如原代细胞、临床样品等）。而近年来发展起来的生物正交反应能通过化学手段在生命活体中进行原位研究，为生物学研究提供了简单高效的工具。特...
You’ve probably heard about Schrödinger’s cat, which famously is trapped in a box with a mechanism that is activated if a radioactive atom decays, releasing radiation. The act of looking in the b...
The brains of wild cats don’t necessarily respond to the same evolutionary pressures as those of their fellow mammals, humans and primates, indicates a surprising new study led by a Michigan State Uni...
Characterizing entanglement of an artificial atom and a cavity cat state with Bell’s inequality
Characterizing entanglement cavity cat state Bell’s inequality
2016/1/22
The Schrodinger’s cat thought experiment highlights the counterintuitive concept of entan-glement in macroscopically distinguishable systems. The hallmark of entanglement is the detection of strong co...
New research from EMBL-EBI shows how repurposing non-coding elements in the genome gave rise to the great ‘mammalian radiation’.Study of gene regulation in 20 mammals provides insight into how species...
Cats and humans have shared the same households for at least 9,000 years, but we still know very little about how our feline friends became domesticated. An analysis of the cat genome led by researche...
L-carnitine Supplemented Extender Improves Cryopreserved-thawed Cat Epididymal Sperm Motility
L-carnitine Epididymal Spermatozoa Cryopreservation Cat
2016/5/16
Cryopreservation of epididymal sperm is an effective technique to preserve genetic materials of domestic cats and wild felids when they unexpectedly die. However, this technique inevitably causes detr...
A colimit decomposition for homotopy algebras in Cat
A colimit decomposition homotopy algebras Cat Category Theory
2012/6/25
Badzioch showed that in the category of simplicial sets each homotopy algebra of a Lawvere theory is weakly equivalent to a strict algebra. In seeking to extend this result to other contexts Rosicky o...
根据GenBank上已有的植物cat基因序列，设计一对兼并引物。在海南岛采集香蕉、巴西橡胶、黄灯笼辣椒、菠萝、甘蔗、番木瓜等作物的叶片并提取总RNA，反转录成cDNA，PCR进行同源克隆。结果获得了巴西橡胶cat-1和香蕉的cat-2基因，而未获得其它4种作物cat相关基因。序列分析发现，巴西橡胶cat-1和香蕉的cat-2基因开放阅读框(ORF)都为1 479 bp，编码492个氨基酸，GenB...
Effective metastability of Halpern iterates in CAT(0) spaces
Proof mining Banach limits metastability nonexpansive mappings CAT(0) spaces
2011/9/13
Abstract: This paper provides an effective uniform rate of metastability (in the sense of Tao) on the strong convergence of Halpern iterations of nonexpansive mappings in CAT(0) spaces. The extraction...
Random groups have fixed points on CAT(0) cube complexes
Random groups fixed points on CAT(0) cube complexes
2011/2/22
We prove that a random group has fixed points when it isometrically acts on a CAT(0) cube complex. We do not assume that the action is simplicial.

Preparation of Schrödinger cat states with cold ions in a cavity beyond the Lamb-Dicke limit
Schrö dinger cat states cold ions the Lamb-Dicke limit
2010/11/8
We investigate the dynamics of a cold trapped ion coupled to the quantized field inside a high-finesse cavity. We have used an approach for preparing the SC states of motion of ion. This approach, bas...
CAT-generation of ideals
CAT-generation of ideals math
2010/11/19
We consider the problem of generating all ideals of a poset. It is a long standing open problem, whether or not the ideals of any poset can be generated in constant amortized time, CAT for short. We ...
