20. SEM was used to observe its surface structure, while IR spectrum indicated that the polymer membrane has COOH and NH3+ functional groups and displays character of the amphoteric ion. 用电子显微镜观察其表面形貌。IR分析表明该
In this process, the For loop will declare avariablenamed counterVar (implicitly as an integer data type). It will also initialize the variable with the value 1. When the loop starts, counterVar is 1, so the first iteration of the process will look as follows: Range (“A1”).Value = ...
Tutorial 2.1 exploits the similarity of interface between atomic-blocks and multi-blocks, and rewrites a program from Tutorial 1, replacing the multi block-lattice by a plain block-lattice. Tutorial 2.2 provides further insight in the multi-block and gives the user the possibility to construct suc...
3a–c). Whereas Loop1–α1 forms the BC-box motif and interacts with ELOC, Loop2–α5 and a C-terminal extension form the predicted ELOA superfamily homology domain (Figs. 2a and 3a). The fold of ELOA α2–α4 and half of α5 is similar to the crystal structure of the ELOA ...
Tertiary folding begins while the protein is being molded into its primary polypeptide sequence. It is known to be guided through this process by chaperones, which are a family of proteins that bind hydrophobic patches and prevent them from being aggregated prematurely into nonfunctional entities. ...
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-...
Sperm whales (Physeter macrocephalus) are highly social mammals that communicate using sequences of clicks called codas. While a subset of codas have been shown to encode information about caller identity, almost everything else about the sperm whale com
{s_{C}\cdot \log(s_{C})}\leq m\cdot \log(m)). Thewhileloop starting at line1.6has at mostncycles; each of these cycles has three steps: (a) finding a pair of communities with\Delta(Q_{t})=0; (b) joining the communities; and (c) decreasingt. The first step implies ...
The GLUT family of transport proteins thereby cooperatively function to provide a supply of glucose in the direction needed for cell metabolic processes while maintaining a remarkably constant blood glucose level (5 mM after fasting in humans) [84, 154]. These glucose transporters are often rate ...
The predictions of the WSME-L model were compared with those of two types of original WSME models: Original model 1 used a uniform contact energy, while Original model 2 used a residue-dependent weighted contact energy similar to that used in the WSME-L model. Fig. 2: Folding of small ...
