The thing to remember about negative step is that stop is always the excluded end, whether it's higher or lower. If you want same slice in opposite order, it's much cleaner to do the reversal separately: e.g. 'abcde'[1:-2][::-1] slices off one char from left, two from right,...
Plastic has become indispensable for human life. When plastic debris is discarded into waterways, these items can interact with organisms. Of particular concern are microscopic plastic particles (microplastics) which are subject to ingestion by several t
The matrices T and S are obtained at the disease-free equilibrium. The global version of the basic reproductive number is calculated by the spectral radius of the NGM41,58: R0 À ~r T S{1Á: ð11Þ Since the explicit expression of the threshold is unavailable, we present the ...
The former method has the advantage of non-leakage of enzymes; if the enzymes are bound by covalent bonds, it is difficult for them to leave the matrix. In contrast, it would be of concern that there is some leakage of enzymes from immobilization matrices that use non-covalent bonding, ...
We used the "psych" R package to conduct visualization treatments on the scSaustttaeinrabdiliitsyt2r0ib18u, 1t0io, xnFOanRdPEcEoRrRrEeVlaIEtiWon coefficient matrices for the data. 7 of 20 In order to identify ESB accurately, we have adopted two steps, including Principal Component Analrye...
While it had a means to communicate with its community via simple secreted molecules ("quorum sensing"), the eventual shift to an aerobic environment led to multi-cellular metazoan organisms, with evolutionary-selected genes to form extracellular matrices, stem cells, stem cell niches, and a ...
Accordingly, goal-matrices are important in MCDAs in order to be able to evaluate different alternatives, in our case clean technologies, according to these goals. We defined three primary goals in line with our study's aim and corresponding to the three dimensions of sustainability: economic, ...
