For this inference, we investigate the effects on self-gravitating implosion with spherically symmetric non-static geometry in the presence of extra force [ 1 + 位 f 2 ( R ) ] L m , that express the cosmic expansion with dark source constraints. Matching conditions are given in which we ...
After discussing some mathematical preliminaries by which we obtain an algebraic relation between the shear and the anisotropy in these theories, we consider two metric ansatzes. In the first, the collapsing metric is considered to be a separable function of the co-moving radius and time, and ...
Example 1: Basic Application of the paste Function in RThe following R code illustrates the basic functionality of the paste R function:paste("This is", 1, "out of", 4, "examples.") # Basic application of paste # "This is 1 out of 4 examples."...
The standard Schrdinger dynamics is modified with the introduction of nonlinear and stochastic terms, which induce the wave function collapse in space. Collapse models predict slight deviations from the standard quantum mechanics predictions, in particular the emission of a "spontaneous radiation", which...
我不知道我能不能找到一个很好的解决办法。我当然可以移除那些中线。我也不喜欢它们，但是它们对于具有...
collapse is a C/C++ based package for data transformation and statistical computing in R. Its aims are:To facilitate complex data transformation, exploration and computing tasks in R. To help make R code fast, flexible, parsimonious and programmer friendly....
In the present work, we have created an R function, collapseRows, that implements a host of widely used collapsing methods. We will describe this function in more detail and present several motivating examples involving gene expression data (mRNA abundances). We explore this function in the conte...
In this case, we are using r’s pastefunction to concatenatevalues into a single string. Introducing The Collapse parameter A key limitation in the input argument example above: we assume we’re concatenating a constant number of arguments. This doesn’t always occur in the real world. Suppose...

——乔伊. R.金 Back in days of yore, 回首昔日时光, Life was simple, maybe a little of a bore. 生活简单,也许有一点厌倦。 Life was good back then, 那时的生活多么美好, Way, way back when. 那是很久,很久以前。 Ladies has(have) dresses adorned with lace,淑女的衣裙镶着蕾丝花边, ...
