This paper suggests an approximate algorithm to solve general 0-1 integer programming problems. This algorithm belongs to the class of lexicographic enumeration algorithms. Theoretical analysis and a strict mathematical proof of convergence property of the algorithm are presented , as well as experimental investigation to engineering structural optimization(More)
BACKGROUND MicroRNA-223 (miR-223) is a hematopoietic lineage cell-specific microRNA. However, a significant amount of miR-223 has been identified in vascular smooth muscle cells (VSMCs) and vascular walls that should not have endogenous miR-223. OBJECTIVES This study sought to determine the sources of miR-223 in normal and atherosclerotic arteries and the(More)
Sorafenib was the only small-molecule drug approved by FDA for treatment of the advanced hepatocellular carcinoma (HCC). Recent study indicated that YM155 was a promising agent for HCC cells with high survivin expression, however, the antitumor activity needs to be further improved. Based on molecular docking and rational design method, a series of(More)
A measurement system of dynamic resistance of vehicle electronic line connector based on PXI Express(PXIe) technology was established. The system hardware was composed of PXIe box, PXIe high speed digitalizer, PXIe arbitrary waveform generator, high precision currency source and so forth. And the system operating interface was designed by LabVIEW, the(More)
—The successive approximation register analog to digital converter (SAR ADC) technique is not yet mature in China mainly because of the imperfect analog module of the SAR ADC. The purpose of this design was to optimize the analog module by designing and making a 8-bit 1MHz SAR ADC and testing a 12-bit SAR ADC theoretically and by simulation. The design of(More)
We demonstrate the fabrication of highly open spherical cages with large through pores using high aspect ratio cellulose nanocrystals with "haystack" shell morphology. In contrast to traditional ultrathin shell polymer microcapsules with random porous morphology and pore sizes below 10 nm with limited molecular permeability of individual macromolecules, the(More)
In order to guide patients on their rehabilitation training based on their own conditions and to decrease repetitive work of the rehabilitative physicians, we propose a personalized physical rehabilitation training system using virtual reality technology. On the one hand, with the 9-dof posture sensor and strength sensor, our system realizes collecting(More)
Leaf area index (LAI) is a critical structural parameter in evaluating physiology and biology of vegetation canopy and ecosystem, which makes its quick and precise measurement necessary though still unrealized owing to the different LAI definitions, diverse suggestions and measurement variance. And virtual plant, virtual reality and virtual instruments (VI)(More)
