Abstract The objective of this work was to determine the accumulation silicon in plant components cauliflower (Brassica oleracea var. botrytis) grown with different levels water replacement and rates Si. experimental design a randomized complete block three conditions (40, 70, 100% evapotranspiration), four Si (0, 50, 100, 150 kg ha-1), replicates. Daily evapotranspiration determined constant t...

The Sex-ratio chromosome (SR) is a widespread, multiply inverted rearrangement of the X chromosome present in several species of Drosophila. Male carriers transmit mostly X-bearing sperm. In the absence of strong counteracting selection, SR is expected to increase rapidly to fixation, causing extinction. The present study incorporates a selection-components analysis of SR in laboratory populati...

We study how dynamical decoupling (DD) pulse sequences can improve the reliability of quantum computers. We prove upper bounds on the accuracy of DD-protected quantum gates and derive sufficient conditions for DD-protected gates to outperform unprotected gates. Under suitable conditions, fault-tolerant quantum circuits constructed from DD-protected gates can tolerate stronger noise and have a l...

Boc protection group could be readily removed in a very mild mechanochemical conditions. In a short reaction time, ball milling of Boc-protected amines with p-toluenesulfonic acid in solvent-free conditions affords corresponding amine p-TsOH salts.

Protected areas are the flagship management tools to secure biodiversity from anthropogenic impacts. However, extent which adjacent with distinct protection levels host different species numbers and compositions remains uncertain. Here, using reef fishes, European alpine plants, North American birds, we show that composition of in Strictly Protected, Restricted, Non-Protected is highly dissimil...
