Previous studies have suggested aberrant expression of membrane B7-H3 in tumor cells. This aim of the study was to determine the expression level of soluble B7-H3 (sB7-H3) in circulation and to subsequently evaluate the clinical significance of circulating B7-H3 in patients with non-small cell lung cancer (NSCLC). The level of circulating B7-H3 was(More)
We consider the problem of learning heuristics for controlling forward state-space beam search in AI planning domains. We draw on a recent framework for “structured output classification” (e.g. syntactic parsing) known as learning as search optimization (LaSO). The LaSO approach uses discriminative learning to optimize heuristic functions for search-based(More)
Beam search is commonly used to help maintain tractability in large search spaces at the expense of completeness and optimality. Here we study supervised learning of linear ranking functions for controlling beam search. The goal is to learn ranking functions that allow for beam search to perform nearly as well as unconstrained search, and hence gain(More)
Beam search is used to maintain tractability in large search spaces at the expense of completeness and optimality. We study supervised learning of linear ranking functions for controlling beam search. The goal is to learn ranking functions that allow for beam search to perform nearly as well as unconstrained search while gaining computational efficiency. We(More)
ETHNOPHARMACOLOGICAL RELEVANCE Banxia Xiexin decoction (BXD), one of a traditional Chinese medicine chronicled in Shang Han Lun, is commonly used to treat gastroenteritis, ulcerative colitis and diarrhea. In our study, we used current biomedical approaches to investigate the therapeutic efficacy of BXD and possible protective mechanism involved in(More)
We perform the first-principles computational study of the effect of number of stacking layers and stacking style of the few-layer black phosphorus (BPs) on the electronic properties, including transport gap, current-voltage (i-v) relation, and differential conductance. Our computation is based on the nonequilibrium Green's function approach combined with(More)
The collective electronic excitation in planar sodium clusters is studied by time-dependent density functional theory calculations. The formation and development of the resonances in photoabsorption spectra are investigated in terms of the shape and size of the two-dimensional (2D) systems. The nature of these resonances is revealed by the(More)
