In the Spray Phase, the source distributes L copies to L distinct relays.

The concatenation of two strings s and t is denoted by s · t, and the concatenation of l copies of a string s is denoted by s l.

The expected NRC value in a region of a gain or loss of l copies can be calculated as E x p e c t e d N R C = (1 − c ) · 1 + c · (1 ± l / P ), where c is the fraction of all cells in the sample containing the CNA and P is the tumor ploidy.

The likelihood for L copies of the original data is denoted by { L(α ; C )} L. It was shown by Lele et al. [ 24, 25] that when L is large enough, π L (�� | C (L )) will converge to a multivariate Normal distribution with the mean given by the MLE of the model parameters and variance-covariance matrix equal to 1/ L times the inverse of the Fisher information matrix for the MLE.

Although more data are desired, these results are comparable to humans where multiple M copies are found in 66% of males of European origin [ 11] and 56% of Japanese males [ 62] and more than one L copy is rarely found [ 63].

Go to the command prompt of the server and type in command prompt osql –L Copy full name of SQL Server and type: OSQL -S -E Execute the following query: sp_password NULL, ", 'sa' GO Open SSMS management console.

The inference of μ is complicated since each run of l single copies may have been produced by an unknown number r of deletion events, either r = l events (the gene-by-gene model) or 1 ≤ r < l - 1 (the random excision model), and these r samples of the distribution ρ turn out not to be independent.

However, in highly expressed genes, n is unlikely to be much smaller than k; thus, both gene length (L) and transcript copy number (n) contribute to the duration of transcription.

Regarding non-human catarrhines, studies concur that a single L opsin copy is generally found in the genomes whereas some studies report that multiple M copies are rare [ 19, 21, 23, 25] yet other studies report that they are common [ 26, 29].

The clones were highly homologous to each other and to the L-type copies.

Ludwig's WRAP-UP

In summary, the phrase "l copies" is grammatically incorrect, though examples can be found in a variety of source domains. Ludwig AI suggests that you should use "1 copy" when only referring to one instance of an item or write the quantity before "copies" such as "2 copies". Predominantly found in scientific and technical contexts, its incorrect grammar means it is unsuitable for formal communication. It is important to use the correct grammatical form and be explicit when referring to the number of copies.
