Pre-mRNAs from thousands of eukaryotic genes can be non-canonically spliced to generate circular RNAs, some of which accumulate to higher levels than their associated linear mRNA. Recent work has revealed widespread mechanisms that dictate whether the spliceosome generates a linear or circular RNA. For most genes, circular RNA biogenesis via backsplicing is far less efficient than canonical spl...

background and aims: tomato yellow leaf curl virus (tylcv) is one of the most destructive viruses of tomato that leads to reduced tomato yield up to 100% in tropical and subtropical regions. in this study, the complete sequence of tylcv isolate from hormozgan province, iran and its recombination evsent was determined. methods: tylcv infected tomato was collected from hormozgan province. total d...

Recently the first author presented exact formulas for the number of 2-periodic binary sequences with given 1-error linear complexity, and an exact formula for the expected 1-error linear complexity and upper and lower bounds for the expected k-error linear complexity, k ≥ 2, of a random 2-periodic binary sequence. A crucial role for the analysis played the Chan-Games algorithm. We use a more s...

Existing changepoint approaches consider changepoints to occur linearly in time; one happens after another and they are not linked. However, data processes may have regularly occurring changepoints, for example, a yearly increase sales of ice-cream on the first hot weekend. Using linear here will miss more global features such as decrease due other product availability. Being able tease these f...

Abstract Periodic Geometry studies isometry invariants of periodic point sets that are also continuous under perturbations. The motivations come from crystals whose structures determined in a rigid form, but any minimal cells can discontinuously change due to small noise measurements. For integer $$k\ge 0$$ k ...
