Even different concentrations of a single compound can be perceived as distinct stimuli93. High species specificity of many sexual chemical signals indicates they often diversify rapidly94. This diversity has made chemical signals an especially useful model of studying the evolution of communication94. ...
摘要: A compound of formula (I) where the substituents have the meanings assigned to them in claim 1 , compositions comprising a compound of formula (I) and the use of such compounds and/or compositions controlling insects, acarines, nematodes or molluscs....

An epoxy resin composition for a printed circuit board includes an epoxy resin; a multi-functional phenol group; a hardening accelerator; and at least one of a compound having a triazine or isocyanurate ring, and a compound containing le... M Arata,N Takano,T Fukuda,... 被引量: 0发表:...
Where a compound only contains nonmetal atoms, a covalent bond is formed by atoms sharing two or more electrons. Nonmetals have four or more electrons in their outer shells (except boron). With these many electrons in the outer shell, it would require more energy to remove the electrons than...
reducer,reducing agent,reductant- a substance capable of bringing about the reduction of another substance as it itself is oxidized; used in photography to lessen the density of a negative or print by oxidizing some of the loose silver
Table 2. Chemical composition of EOs from A. ampeloprasum var. holmense, cultivars ‘Irsina’ and ‘Contursi T.’. It must be emphasized that in many cases, the data on allicin do not correspond with what is reported in the literature. This is because the compound is very unstable and...
The fruits of the L. kamtschatica cultivar ‘Aurora’ contained the highest amount of ascorbic acid in their composition, approximately 22% more compared to ‘Lori’, which had the highest content of this compound among L. emphyllocalyx cultivars. The highest total polyphenol content was found...

Understanding transcriptional responses to chemical perturbations is central to drug discovery, but exhaustive experimental screening of disease-compound combinations is unfeasible. To overcome this limitation, here we introduce PRnet, a perturbation-conditioned deep generative model that predicts transcriptional ...
