We now describe these groups briefly. To obtain T, divide the group of diffeomorphisms of the n — 1 sphere S" by the normal subgroup of those diffeomorphisms that are extendable to the w-ball. See [2] for details. The set 0 is the set of /-equivalence classes of closed, oriented, differentiable w-manifolds that are homotopy spheres. If M is an oriented manifold, let —If be the oppositely orient...
This paper is the fifth and final in a series on embedded minimal surfaces. Following our earlier papers on disks, we prove here two main structure theorems for nonsimply connected embedded minimal surfaces of any given fixed genus. The first of these asserts that any such surface without small necks can be obtained by gluing together two oppositely–oriented double spiral staircases; see Figure...
The activity of locus control regions (LCR) has been correlated with chromatin decondensation, spreading of active chromatin marks, locus repositioning away from its chromosome territory (CT), increased association with transcription factories, and long-range interactions via chromatin looping. To investigate the relative importance of these events in the regulation of gene expression, we targe...
Available online 15 January 2014 To speed up strategic alliance in R&D activities, different forms of R&D organization structures can be summarized into different roles including the input-oriented, the output-oriented, and the matrix organization structure. Themost commonmode of strategic alliance consists of horizontal and vertical integrations. However, the study adopting absorptive capacity...
c-myc is essential for cell homeostasis and growth but lethal if improperly regulated. Transcription of this oncogene is governed by the counterbalancing forces of two proteins on TFIIH--the FUSE binding protein (FBP) and the FBP-interacting repressor (FIR). FBP and FIR recognize single-stranded DNA upstream of the P1 promoter, known as FUSE, and influence transcription by oppositely regulating...
The regulation of gene expression is essential for normal functioning of biological systems in every form of life. Gene expression is primarily controlled at the level of transcription, especially at the phase of initiation. Non-coding RNAs are one of the major players at every level of genetic regulation, including the control of chromatin organization, transcription, various post-transcriptio...
Transcription of the genomic region involved in gas vesicle formation in Halobacterium salinarum (p-vac) and Haloferax mediterranei (mc-vac) is driven by two divergent promoters, P(A) and P(D), separated by only 35 nt. Both promoters are activated by the transcription activator GvpE which in the case of P(mcA) requires a 20-nt sequence (UAS) consisting of two conserved 8-nt sequence portions lo...
