Hypertension plays an important role in the pathogenesis of stroke,which,however,is only known at the blood pressure level.The relationship between circadian rhythm of blood pressure(especially the circadian rhythm disorder of blood pressure)and stroke has been a hot research topic.This article reviews the concept of circadian rhythm of blood pressure,classification of circadian rhythm disorder of blood pressure,and the relationship of circadian rhythm disorder of blood pressure with ischemic stroke.

Universalization, serialization and modularization are the three most important metrics in standardization of manufacturing. Developing with innovation of modern large-scale industrial production, a variety of methods were proposed to help enterprises to improve products’ applicability, prevent trade barriers, and promote technical cooperation. Meanwhile, some metrics were designed to evaluate or optimize these standardized procedures. However, no systematically quantitative model has been proposed to evaluate the standardization of equipment so far. In order to break the barrier, a quantitative analysis based evaluation model of equipment system is proposed in this paper, in which, universalization, serialization and modularization indices are defined based on heterogeneous information network. Comparing the results performed by the proposed model with experts’ evaluation, the metrics in proposed model can reveal the objective standardization of equipments.

Aim to a weapon platform get objects information in aspect of precision stroke beyond visual range, study on a novel method of antiterrorism sensor network. Raise formative network method based on control in order to settle for demands for antiterrorism sensor network. The network topology is distributed plane peer to peer self-organized structure. In the particular geography district, nodes carry on closed loop control, discover routing and maintain it according to the need that the delivering data packets and the state of their link. The simulation results show that the method has characteristic of none-center, self-organized, rapid dynamic which antiterrorism sensor network has. The novel method can be applied in execrably antiterrorism environment.

In the smart power grids construction and for the needs of the power distribution reliability，and for the overhaul and maintenance of the power equipment, it is important for all the operation equipment condition being under monitoring. All equipment has its own characteristics. These characteristics give the customizing messages for monitoring the equipment condition. For the overhead lines insulators, its leakage current mainly mirror insulating property and can give out the insulating strength degrading in time. So trying to monitor the insulators leakage current is significant for Electrical safety. In this paper, the polluted insulator leakage current generating mechanism and characteristics in the operating voltage be analyzed, the actual use of the leakage current on-line monitoring methods and equipment be compared. Based on MSP430 single chip, one facility insulator leakage current online monitoring device is developed. This on-line monitoring device make up of leakage current signal acquisition unit, periodically the leakage current signal into the signal processing unit, the microcontroller to process data effectively, and given the alarm in case of problems, and the data stored by the host computer communication module and communication. By preliminary testing on the good and polluted insulator, the test data reflect the polluted insulator leakage current changed condition, and can find out fault insulators nicely.

As a treatment of depression, the efficacy of conventional repetitive transcranial magnetic stimulation (rTMS) is limited, and symptoms recurrence is easy to occur after the treatment. This study aimed to examine the efficacy and safety of sleep electroencephalogram modulated repetitive rTMS (SEM-rTMS) in the treatment of depression.After 7 days without psychoactive medication, 164 patients with clinically defined depression were randomly divided into 3 groups: SEM-rTMS group (n = 57), conventional rTMS (C-rTMS, n = 55) group and sham-rTMS group (n = 52). Every patient was treated with the corresponding method for 30 minutes everyday for 10 days. Before and after scores on the 24-item Hamilton rating scale for depression (HAMD-24) and the clinical outcome on the 10th day of therapy for all subjects were analyzed.Twenty-two cases in the SEM-rTMS group obtained improved mood as compared to 6 in the C-rTMS group and 2 in the sham-rTMS group (χ(2) = 15.89, P = 0.0004). After completion of the rTMS phase of the protocol, a (51 ± 5)% reduction of HAMD-24 scores from the baseline in the SEM-rTMS group was found compared with a (34 ± 4)% in the C-rTMS group (q = 26.09, P = 0.001) and a (14 ± 3)% in sham-rTMS group (q = 57.53, P = 0.000). The 88% total effective rate in the SEM-rTMS group was significantly higher than 68% in the C-rTMS group and 20% in the sham-rTMS group (χ(2) = 12.01, P = 0.0025). No significant side effects were noted.SEM-rTMS is an effective and safe way for treating depression with repetitive transcranial magnetic stimulation (ChiCTR-TRC-00000438).

This work presents a simple compensation method for widening the viewing angle of transflective liquid-crystal displays (TR-LCDs). For an off-axis light, the slow axis of a biaxial film shifts linearly as the Nz factor is varied. By using this optical characteristic of a biaxial film, the broadband condition of broadband circular polarizers exactly holds over a full 80 degrees viewing cone, thus eliminating the off-axis light leakage to widen the viewing angle of TR-LCDs. Based on the proposed compensation method, the TR-LCDs theoretically have a wide spectral bandwidth and a viewing angle of 80 degrees for contrast-ratio (CR)100:1 and30:1 in transmissive and reflective modes, respectively. Experiments also show that the proposed TR-LCD has a viewing angle of over the entire 80 degrees and 65 degrees viewing cone in T-mode and R-mode, respectively, for CR10:1. The proposed TR-LCD is highly promising for mobile display applications.

This work proposes a viewing angle switching (VAS) panel using twisted-nematic liquid-crystals (TN-LCs). Calculations reveal that, in a low voltage regime, a TN-LC behaves optically as a high twisted (~90°) TN-LC in a vertical direction but as a low twisted (
