Trigeminal neuralgia (TN) is a pain syndrome characterized by pain in the trigeminal area often accompanied by a brief facial spasm or tic. The purpose of our study was to investigate the efficacy and clinical utility of CT-guided pulsed radiofrequency (PRF) for treatment of TN. Patients who were diagnosed with severe TN between September 2010 and October(More)
The purpose of this article is to investigate the similarities and differences in the usage of discourse markers such as because, so, and, etc. among the following three types of university students: native speakers of English (NS), non-native Chinese students (CNNS, mainland Chinese), and non-native Japanese students (JNNS). All the CNNS and JNNS have(More)
OBJECTIVE The aim of this study was to determine the influence of birth weight, a marker of fetal growth, on the development of later impaired glucose metabolism throughout the life span of people living in China. RESEARCH DESIGN AND METHODS We recorded detailed anthropometric data including height, weight, and health status and measured blood glucose(More)
BACKGROUND Sphenopalatine ganglion percutaneous radiofrequency thermocoagulation treatment can improve the symptoms of cluster headaches to some extent. However, as an ablation treatment, radiofrequency thermocoagulation treatment also has side effects. OBJECTIVE To preliminarily evaluate the efficacy and safety of a non-ablative computerized(More)
Fast economic growth and rapid urbanization present a challenge to the limited urban land resources of China. Specifically, they encourage a shift in the concentration on the surface of land parcels to the space above and below them. Recent development in land utilization in developed cities has broken the traditional frame of the parcel-based or 2D(More)
The problem of joint states dimension reduction and quantizer design under communication constraints was discussed for states estimation in quantized linear dynamic systems. In order to meet the requirements of transmit power constraint and the constraints of number and bandwidth of the parallel channels, the structure of DPCM (differential pulse code(More)
This article presents a new method to illustrate the feasibility of 3D topology creation. We base the 3D construction process on testing real cases of implementation of 3D parcels construction in a 3D cadastral system. With the utilization and development of dense urban space, true 3D geometric volume primitives are needed to represent 3D parcels with the(More)
Abstract-Network covert channels can be used to transfer secret information in network protocols. For a kind of network covert channels hidden in overt sources with fixed probability distribution, we propose a modified Pearson chi-square test which improves detection accuracy. We incorporated adjacent probability values and divided the new distribution into(More)
