  • System and method for associating images with semantic entities

    A system and computer-implemented method for associating images with semantic entities and providing search results using the semantic entities. An image database contains one or more source images associated with one or more images labels. A computer may generate one or more documents containing the labels associated with each image. Analysis may be performed on the one or more documents to associate the source images with semantic entities. The semantic entities may be used to provide search results. In response to receiving a target image as a search query, the target image may be compared with the source images to identify similar images. The semantic entities associated with the similar images may be used to determine a semantic entity for the target image. The semantic entity for the target image may be used to provide search results in response to the search initiated by the target image.

  • Recycling the danger via lipid droplet biogenesis after autophagy

    Yuan Li   Wei-Xing Zong   Wen-Xing Ding  

    Fatty acids are an important cellular energy source under starvation conditions. However, excessive free fatty acids (FFAs) in the cytoplasm cause lipotoxicity. Therefore, it is important to understand the mechanisms by which cells mobilize lipids and maintain a homeostatic level of fatty acids. Recent evidence suggests that cells can break down lipid droplets (LDs), the intracellular organelles that store neutral lipids, via PNPLA2/adipose triglyceride lipase and a selective type of macroautophagy/autophagy termed lipophagy, to release FFAs under starvation conditions. FFAs generated from LD catabolism are either transported to mitochondria for β-oxidation or converted back to LDs. The biogenesis of LDs under starvation conditions is mediated by autophagic degradation of membranous organelles and requires diacylglycerol O-acyltransferase 1, which serves as an adaptive cellular protective mechanism against lipotoxicity.

  • Explicit-form complex orthogonal design for space-time block codes

    Yuan Li   Chen Yuan   HaiBin Kan  

    In this paper, we present a construction of complex orthogonal design for space-time block codes in any number of antennas. Our construction achieves both the maximal rate and minimal delay. So far as we know, our construction is the first explicit-form construction, which has asymptotically optimal time complexity and space complexity. And new representation of complex orthogonal design might bring advantages in analyzing some properties. In addition, when the number of antennas n = 1, 2, 3 (mod 4), our construction satisfies transceiver signal linearization property, which allows for design of low complexity channel equalizers and interference suppressing filters.
