A sequence of numbers a1,a2,a3,... is defined by an+1=k(an+2)an;n∈N where k is a constant. Given that: i) The sequence is a periodic sequence of order 3. ii) a1=2 Show that k2+k−2=0 Period...
A sequence of numbers a1, a2, a3, . . . is defined as follows: a1 = 3, a2 = 5, and every term in the sequence after a2 is the product of all terms in the sequence preceding it, e.g., a3 = (a1)(a2) and a4 = (a1)(a2)(a3). If an = t and n > 2, what is th

The final global dataset of viral sequence, diversity, distribution, and biosafety recommendation of arbovirus and ASV consist of one virus meta information file (.xlsx), one virus nucleotide sequence file (.fna), and one amino acid sequence file (.faa). The data screening and integration proce...
To confirm the interaction between BoERF1L and the bait, we fused the full-length coding sequence of BoERF1L to the yeast GAL4 transcriptional activation domain (GAL4-AD).Ms-cd1promoter fragments (-624 to -559) WTpro (fromMs-cd1PWT) and MTpro (fromMs-cd1PΔ-597) (Supplementary Fig....

To make things confusing, if I highlighted cells containing an arbitrary set of numbers, like 1, 17, and 20, Excel would repeat this pattern since there's no logical sequence to continue. How to format data in Excel If you copied data from another source or manually entered it yourself...
Nonparametric bagging clustering methods are studied and compared to identify latent structures from a sequence of dependent categorical data observed along a one-dimensional (discrete) time domain. The frequency of the observed categories is assumed to be generated by a (slowly varying) latent signal...
