Introduction classically, cell signalling has been viewed in terms of linear pathways that lead from external or internal stimuli to cellular effectors. But this simple view developed more as a means to visualize and to understand the individual components of these complex systems, rather than to reflect reality. it is now clear that, in most cases, cell signalling is much more complex and invo...
To improve commercial grapevine cultivars, it is necessary to apply such methods that by cultivation of a certain number of vines in a certain area, higher yield could be harvested. To achieve such a goal, healthy stocks with resistant to pests and diseases, high fructification and high quality of vines are needed. All these properties can be obtained successfully through clonal selection. Viti...
Primary bud necrosis (PBN) of grapevine, which is a physiological disorder, seriously decreases the fruit yield of vineyards. This research was carried out to determine the effects of mineral deprivation on increasing the incidence of PBN in ‘Askari’ table grapes in Sisakht region of Southwest of Iran. For this purpose, the changes of mineral elements in leaves and PBN percentage were estimated...
Damage Potential of Rose Chafer and Japanese Beetle (coleoptera: Scarabaeidae) in Michigan Vineyards
Responses of young non-fruiting grapevines, Vitis labrusca (L.) var. ‘Niagara’, to defoliation were examined at two stages of vine growth when beetles typically infest vineyards. In the first experiment, vines were caged and subjected to two weeks of feeding by 0, 10, 20, or 40 adult Macrodactylus subspinosus Fabricius (Scarabaeidae: Macrodactylini) during bloom, or to the same range of adult P...
high temperature is the most important limiting factor for plant growth in many regions. this problem is very serious because of a heading global warming phenomenon. so study of high temperature effects on different cultivars and species and finding out solution to improve plant tolerance is necessary. in this research, effect of mycorrhizalarboscular fungus on some physiological traits of grap...
We present a sampling algorithm for a regular vine on n variables which starts at an arbitrary variable. A sampling order whose nested conditional probabilities can be written as products of (conditional) copulas in the vine and univariate margins is said to be implied by the regular vine. We show that there are 2 implied sampling orders for any regular vine on n variables. We show that two reg...
Invasive species are not new phenomena in U.S. agriculture, as illustrated by these 1920s lyrics from the Boll Weevil folksong. The boll weevil entered the United States via Mexico in the 1890s, and by the 1920s, this pest had spread to all cotton producing states, wiping out tens of thousands of acres of cotton, costing billions of dollars, and literally driving thousands of farmers off the la...
Short internet video clips like vines present a significantly wild distribution compared to traditional video datasets. In this paper, we focus on the problem of unsupervised action classification in wild vines using traditional labeled datasets. To this end, we use a data augmentation based simple domain adaptation strategy. We utilize semantic word2vec space as a common subspace to embed vide...
