Cytokinesis partitions the cell by a cleavage furrow in animals but by a new cross wall in plants. How this new wall assembles at the molecular level and connects with the mother cell wall remains unclear. A lethal Arabidopsis embryogenesis mutant designated root-, shoot-, hypocotyl-defective (rsh) provides some clues: RSH encodes extensin AtEXT3, a(More)
This paper presents a new algorithm to automatically solve algebra word problems. Our algorithm solves a word problem via analyzing a hypothesis space containing all possible equation systems generated by assigning the numbers in the word problem into a set of equation system templates extracted from the training data. To obtain a robust decision surface,(More)
Search and recommendation systems must include contextual information to effectively model users' interests. In this paper, we present a systematic study of the effectiveness of five variant sources of contextual information for user interest modeling. Post-query navigation and general browsing behaviors far outweigh direct search engine interaction as an(More)
Production of biofuels derived from microbial fatty acids has attracted great attention in recent years owing to their potential to replace petroleum-derived fuels. To be cost competitive with current petroleum fuel, flux toward the direct precursor fatty acids needs to be enhanced to approach high yields. Herein, fatty acyl-CoA metabolism in Saccharomyces(More)
MiR-145 could regulate tumor growth, apoptosis, migration, and invasion. In our present study, we investigated its role in epithelial-mesenchymal transition (EMT). Expression of miR-145 was decreased in breast tumor tissues at T3&4 stages in comparison with those at T1&2. Over-expression of miR-145 mimics enhanced protein levels of E-cadherin and dampened(More)
BACKGROUND Consumer use of mobile devices as health service delivery aids (mHealth) is growing, especially as smartphones become ubiquitous. However, questions remain as to how consumer traits, health perceptions, situational characteristics, and demographics may affect consumer mHealth usage intentions, assimilation, and channel preferences. OBJECTIVE We(More)
Stable transformation of tomato (Lycopersicon esculentum cv Ailsa Craig) plants with a construct containing the antisense sequence for the receiver domain and 3'-untranslated portion of the tomato ethylene receptor (LeETR1) under the control of an enhanced cauliflower mosaic virus 35S promoter resulted in some expected and unexpected phenotypes. In addition(More)
We introduce a method for evaluating the relevance of all visible components of a Web search results page, in the context of that results page. Contrary to Cranfield-style evaluation methods, our approach recognizes that a user's initial search interaction is with the result page produced by a search system, not the landing pages linked from it. Our key(More)
The unique optical properties of semiconducting single-walled carbon nanotubes (SWNTs) are exquisitely sensitive to variations in the surrounding environments. Here, we have studied the redox chemistry of SWNTs encased with double-stranded deoxyribonucleic acid (DNA) reacted with either hydrogen peroxide H2O2 or glucose in the presence of the glucose(More)
Metformin has been reported having potential anticancer effect on kinds of solid tumors, but its role in combined small-cell lung cancer (C-SCLC) remains indistinct. This study aimed to explore whether metformin use has a prognosis benefit in diabetic C-SCLC patients. A total of 259 C-SCLC patients with diabetes were enrolled in our study. The(More)
