Automatically Generating and Rendering Native Advertisements

Systems and methods for automatically generating and rendering a native advertisement for display on a client device when the client device is accessing a publisher’s webpage are described. A template node among a number of nodes of a publisher’s webpage can be selected to specify a content item that the publisher wants the native ad looks like. When the publisher’s webpage is loaded by a web browser of a client device, the native ad can be rendered by the browser using a JavaScript downloaded from an advertisement server. The rendering process can include extracting a number of formatting attributes for the native ad from the template node, mapping the formatting attributes with a proper template from a number of predefined templates maintained by an ad server, and loading the proper template from the ad server to render the content of the native advertisement in its corresponding inline frame

Cell ultrastructure and physiological changes of potato during cold acclimation

Potato cultivars are sensitive to frost; thus, freezing damage often results in heavy loss of potato yield. In this study, a wild potato species S. acaule W3, which is frost-resistant and has cold acclimation ability, and S. cardiophyllum Cph12, which is frost-sensitive and cannot be cold-acclimated, were used to research the cell structure and physiological changes that occur during cold acclimation. The results showed that frost resistance of W3 was enhanced by cold acclimation, but frost resistance of CPh12 did not change. The subcellular characters related to the enhancement of freeze resistance mainly include a decrease in the proportion of the vacuole to total cell volume, integrity of the biomembrane, and orderly arrangement of grana lamellae. At the physiological level, the W3 damage index was correlated with membrane lipid peroxidation system indices (including chlorophyll, malondialdehyde and the difference between relative conductivity before and after freezing treatment in W3), the activity of the antioxidant enzymes superoxide dismutase and catalase, the contents of the osmotic regulators proline and soluble protein, and the contents of the endogenous hormones salicylic acid (SA), indole acetic acid/abscisic acid (IAA/ABA), and SA/ABA, which indicated that cold acclimation enhanced the freezing resistance of wild potato species W3 by enhancing the original cold-tolerance characters. The results could be useful to clarify the cold resistance mechanism of plants, and to provide a theoretical basis for cold resistance breeding.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
