Principal component extraction is an efficient statistical tool which is applied to data compression, feature extraction, signal processing, etc. Representative algorithms in the literature can only handle real data. However, in many scenarios such as sensor array signal processing, complex data are encountered. In this paper, the complex domain generalized(More)
Most existing propeller-driven, cruising AUVs operate with a support ship and have an endurance of about one day. However, many oceanographic processes evolve over days or weeks, requiring propeller-driven vehicles be attended by a ship for complete observation programs. The Monterey Bay Aquarium Research Institute (MBARI) developed the 105 kg(More)

AIM The present study was aimed at evaluating present randomized controlled trials (RCTs) regarding the effect of alpha-adrenoceptor agonists on vasovagal syncope (VVS). METHODS According to inclusion and exclusion criteria, articles were selected from medical electronic databases. RCTs were then assessed based on the Juni assessment, and meta-analysis(More)
BACKGROUND The study evaluated the effect of hyperandrogenism (HA) in polycystic ovary syndrome (PCOS) on metabolic parameters. METHODS We searched PubMed, EMBASE, Cochrane, Web of Science, Chinese Biomedical Database (CBM), China National Knowledge Infrastructure (CNKI), WanFang data and VIP for clinical observational studies. The study evaluated PCOS(More)
BACKGROUND Breast cancer (BC) is the most common malignant tumor in females. This study investigated the role and utility of CTC monitoring in evaluating the prognosis of triple-negative breast cancer patients. MATERIAL AND METHODS We enrolled 286 female triple-negative breast cancer patients who were diagnosed at and received radical resection surgery in(More)
A POSS-supported Pd-diimine complex, an homogeneous analog of a supported catalyst, was synthesized and applied for the unique synthesis of narrow-distributed polyethylene chains containing an end-tethered POSS nanoparticle by ethylene "living" polymerization.
In order to achieve better network communication between embedded devices, we complete a network driver program based on embedded processor platform. In the definition of internal data type, We choose little-endian due to our processor and use LwIP build-in error code in arch.h file. Moreover, LwIP provides users with a convenient configuration at the(More)
OBJECTIVE To develop a portable field anesthesia machine system suitable for the medical first-aid on the spot. METHODS The three-dimensional structure of PFAM was designed with modeling software of Pro/E and manufactured according to the GB9706.29 and other national standards. RESULT Due to its small footprint and very light weight, PFAM is completely(More)
