- We investigate the role of identity and self-image consideration under "pay-what-you-want" pricing. Results from three field experiments show that often, when granted the opportunity to name the price of a product, fewer...
- Live imaging of nascent RNA dynamics reveals distinct types of transcriptional pulse regulation
[作者:Muramoto, T; Cannon, D; Gierlinski, M; Corrigan, A; Barton, GJ; Chubb, JR,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:7350-7355 , 文章类型: Article,,卷期:2012年109-19]
- Transcription of genes can be discontinuous, occurring in pulses or bursts. It is not clear how properties of transcriptional pulses vary between different genes. We compared the pulsing of five housekeeping and five dev...
- Mechanical impulses can control metaphase progression in a mammalian cell
[作者:Itabashi, T; Terada, Y; Kuwana, K; Kan, T; Shimoyama, I; Ishiwata, S,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:7320-7325 , 文章类型: Article,,卷期:2012年109-19]
- Chromosome segregation machinery is controlled by mechanochemical regulation. Tension in a mitotic spindle, which is balanced by molecular motors and polymerization-depolymerization dynamics of microtubules, is thought t...
- Phage-based molecular probes that discriminate force-induced structural states of fibronectin in vivo
[作者:Cao, LZ; Zeller, MK; Fiore, VF; Strane, P; Bermudez, H; Barker, TH,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:7251-7256 , 文章类型: Article,,卷期:2012年109-19]
- Applied forces and the biophysical nature of the cellular microenvironment play a central role in determining cellular behavior. Specifically, forces due to cell contraction are transmitted into structural ECM proteins a...
- Direct observation of stick-slip movements of water nanodroplets induced by an electron beam
[作者:Mirsaidov, UM; Zheng, HM; Bhattacharya, D; Casana, Y; Matsudaira, P,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:7187-7190 , 文章类型: Article,,卷期:2012年109-19]
- Dynamics of the first few nanometers of water at the interface are encountered in a wide range of physical, chemical, and biological phenomena. A simple but critical question is whether interfacial forces at these nanosc...
- Genomic landscape of human allele-specific DNA methylation
[作者:Fang, F; Hodges, E; Molaro, A; Dean, M; Hannon, GJ; Smith, AD,期刊:Proceedings of the National Academy of Sciences of the United States of America, 页码:7332-7337 , 文章类型: Article,,卷期:2012年109-19]
- DNA methylation mediates imprinted gene expression by passing an epigenomic state across generations and differentially marking specific regulatory regions on maternal and paternal alleles. Imprinting has been tied to th...
