B3G wireless networks are expected to be characterized by the pouring of diversified services supported by different operators. In parallel with this, how to efficiently utilize the limited radio spectrum and guarantee the operator¿s profits has become a joint economical and technical problem. As a possible solution, in this paper, we set forth a novel(More)
Mounting evidence suggests a causal relationship between specific bacterial infections and the development of certain malignancies. However, the possible role of the keystone periodontal pathogen, Porphyromonas gingivalis, in esophageal squamous cell carcinoma (ESCC) remains unknown. Therefore, we examined the presence of P. gingivalis in esophageal mucosa,(More)
OBJECTIVE We aimed to evaluate the incidence and predisposing factors of postoperative voiding difficulty and mesh-related complications. METHODS In this prospective cohort study, 206 consecutive women with advanced pelvic organ prolapse underwent surgical repair with the Prolift mesh kit at Peking Union Medical College Hospital, with a mean follow-up of(More)
Learning Dependency-Based Compositional Semantics Suppose we want to build a system that answers a natural language question by representing its semantics as a logical form and computing the answer given a structured database of facts. The core part of such a system is the semantic parser that maps questions to logical forms. Semantic parsers are typically(More)
An increasing body of evidence indicates that miRNAs have a critical role in carcinogenesis and cancer progression; however, the role of miRNAs in the tumorigenesis of adencarcinoma of gastric esophageal junction (AGEJ) remains largely unclear. The SGC7901 and BGC-823 gastric cancer cell lines were used. The expressions of miR-645 and IFIT2(More)
Treatment of hematological malignancies by adoptive transfer of activated natural killer (NK) cells is limited by poor postinfusion persistence. We compared the ability of interleukin-2 (IL-2) and IL-15 to sustain human NK-cell functions following cytokine withdrawal to model postinfusion performance. In contrast to IL-2, IL-15 mediated stronger signaling(More)
Gastric cardia adenocarcinoma (GCA), which occurs at the gastroesophageal boundary, is one of the most malignant types of cancer. Over the past 30 years, the incidence of GCA has increased by approximately sevenfold, which has a more substantial increase than that of many other malignancies. However, as previous studies mainly focus on non-cardia gastric(More)
This article researChes for 10kV transmission cable form the ground substation to the underground central substation in the coal mine. The transient traveLing wave signal of the cable fault is disposed by the wavelet transformation based on the cable traveLing wave transmission theory. The traveLing wave head of the cable fault can be more accurately(More)
