= 0,这时候如果使用while语句,对于 0 这个数的计数位就会变成 0位而出现错误,但这时候如果使用do-while语句的话,就巧妙解决了这个问题。 2.0学习体会 反馈一下对上次学习体会的总结,这几周来的调整来说,没有太大的进步,但不是没有完全的进步,从数学的学习当中初步发现了结构化的思维逻辑,并且打算应用在c语言...
Many bacteria and archaea possess a two-dimensional protein array, or S-layer, that covers the cell surface and plays crucial roles in cell physiology. Here, we report the crystal structure of SlpA, the main S-layer protein of the bacterial pathogen Clos
Although it is unclear how the conformational change influences Pol II activity, it is possible that this occurs by restricting the mobility of the trigger loop. The trigger loop was shown to play a key role in the NTP addition cycle during transcription elongation42. Upon latch binding, the ...
The object of this paper is to study the realization of a sequential machine from several smaller machines. The basic tools in this investigation are the partitions with the substitution property and the partition pairs. It is shown that to every (loop-free) realization of a sequential machine ...
Visualization based on a projection into 3D space [39]: 3D cluster-guided projection, where the 3D subspace is determined by centroids of 4 clusters 0, 1, 3, 5.© ACM. While this approach works well with low- to medium-dimensional datasets, it is difficult to apply to large high-...
The proteins of the SLC2 family have 12 transmembrane spans (TMs 1-12) with intracellular N- and C-termini. Signature motifs in the GLUTs include highly conserved salt bridging motifs RXGRR between cytoplasmic loop of TM2 and TM3, with a repeated of the salt bridge sequence between the cyto...
In this paper, we discretize the KdV equation in space by finite differences while preserving the skew-symmetry of the Poisson structure. The resulting skew-gradient system of ordinary differential equations (ODEs) preserves the energy, momentum, and mass at the discrete level. The resulting semi-...

Accurately annotating topological structures (e.g., loops and topologically associating domains) from Hi-C data is critical for understanding the role of 3D genome organization in gene regulation. This is a challenging task, especially at high resolution
