High-speed low-power matched filter plays an important role in the fast despreading of spread-signals in wideband code division multiple access (W-CDMA) mobile communications. In this paper, we describe the algorithm and the VLSIarchitecture of a complex matched filter chip implemented by our proposed digital-controlled analog parallel operational circuits.… (More)

We confirmed that the porous PVA dried gel with GNPs embedded in the network, which can be prepared very conveniently, is a stable and ultrasensitive 3D SERS substrate. The existence of the micropores within the gel is necessary for the ultrahigh sensitivity, and embedding of GNPs in the penetrable gel results in high stability.
Resistance to chemotherapy remains a major obstacle for the effective treatment of oral squamous cell carcinoma (OSCC). Evidence for the involvement of exosomes as important regulators of cisplatin chemoresistance in OSCC is still poorly understood. Our objective of this study was to explore the roles for exosomes in modulating key cellular pathways… (More)
Introduction Absenteeism has been considered as a potential indicator for the early detection of infectious disease outbreaks in population, especially in primary schools. However, in practice this data are often characterized by an excess of zeros and spatial heterogeneity. In a project on integrated syndromic surveillance system (ISSC) in rural China(1),… (More)
Poly(propargyl pyridinium bromide), a kind of conjugated polyelectrolyte with polyacetylene as the backbone and pyridinium as side groups, was synthesized simply via reaction between pyridine and propargyl bromide under mild conditions. The resultant polymer was characterized by (1)H NMR, elemental analysis, FT-IR, and GPC-MALLS. An alkyne group was… (More)
Methods A total of 167 health facilities including 2 county hospitals, 15 township hospitals and 150 village health stations were sampled as surveillance sites in 2 counties in Jiangxi province, China. Health facility visits of patients with ten major symptoms including fever, cough, sore throat, diarrhea, and nausea/vomiting, together with their age and… (More)
BACKGROUND The primary unit of tuberculosis (TB) medical care in China is the county TB dispensary or county designated hospital (CTD), where patients can receive free diagnosis and treatment. However, a substantial number of patients seek their anti-TB treatment from general health facilities (Non-CTDs). This study aimed to investigate the first anti-TB… (More)
Nanoparticles sized tens of nm with not only a highly complex but also a highly regular nanostructure, although ubiquitous in nature, are very difficult to prepare artificially. Herein, we report efficient solution-based preparation of narrow-disperse ABC three-segment hierarchical nanoparticles (HNPs) with a size of tens of nm through a three-level… (More)
