PURPOSE A possible carcinogenic role of human papillomavirus (HPV) has been investigated in esophageal squamous cell carcinoma (ESCC) for nearly 30 years with mixed results. We performed a meta-analysis to assess the prevalence of "high-risk" HPV, HPV-16/18, in this disease. We also evaluated the association between infection with HPV-16/18 and ESCC risk by(More)
Intravenous leiomyomatosis (IVL), showing unusual growth patterns of uterine leiomyoma, is a rare neoplasm characterized by intravascular proliferation of a histologically benign-looking smooth muscle cell tumor mass, but not invading the tissue. To date, less than 300 cases have been reported and fewer than 100 cases with cardiac involvement. Imaging(More)
AIM To study the metabolic profile of human umbilical mesenchymal stem cells (HUMSC) and adipogenic differentiation by nuclear magnetic resonance (NMR) spectroscopy. METHODS HUMSC isolated from human umbilical cord stroma were induced to adipocytes over 2 wk by adding dexamethasone, 3-isobutyl-1-methylxanthine, indomethacin, and insulin to the culture(More)
AIM To present computed tomography (CT) findings of different histological subtypes of parotid gland masses in detail and to establish diagnostic strategy. METHODS From January 2009 to November 2011, 56 patients were collected through the histopathology and Picture Archiving and Communication Systems records, which revealed 5 basal cell adenoma (BCA), 16(More)
This paper presents a fault diagnosis method for power transformer. Fault diagnosis plays an importance role in the efforts for transformer diagnosis to shift form “preventive maintenance” to “condition based maintenance” (CBM), and consequently to reduce the maintenance cost. Ever since its birth, numerous techniques have been(More)
For the purpose of improving native detective method based on signature matching of traditional anti-virus software and inadequate performance of dynamic testing, the researchers demonstrate a new static detection model of malicious PDF documents based on naive Bayes classifier technology. The model considers with exploit techniques of heap spray,(More)
PURPOSE Infected device explantation is increasingly necessary given the rapid growth in cardiac rhythm management device (CRMD) implantation in China. However, some patients with CRMD infection are unlikely to be capable of paying for a new device. Reassuringly, evidence suggests that reuse of cardiac devices can be safe and feasible. In this study, we(More)
In frequency-domain blind source separation of convolutive mixtures, the DFT coefficients of mixture frame are employed to estimate the mixing matrix on each frequency bin. Based on the relation between partial convolution and circular convolution, we propose a multi-inconsecutive-frames moving average method to produce new frame for DFT to substitute the(More)
In this paper, a power-oriented sink node placement strategy with one-hop topology for wireless body area networks (WBANs) is proposed. With lower power consumption as constraint condition, the optimal position of the sink node is selected. As a result, the network topologies are designed. The measurement results confirmed the proposed strategy by two(More)

In this paper, iterative learning control problem of continuous-time system with variable initial condition is considered. Based on the two-dimensionality of the overall learning system, a continuous-discrete two-dimensional (2D) learning system is established. The proposed error system describes entire dynamics involved in iterative learning including the(More)
