To explore the time characteristics of shoulder pain after laparoscopic gynecological operation.We conducted prospective clinical observations and literature review. We studied 442 cases surgery. used a visual analogue scale to evaluate patients at different points operation. searched English The observation these studies included 12-24 hours or first day surgery, least one point before this point.The total incidence was 68%. More than 90% begin feel on not 26 articles observed severity...

Tumor necrosis factor-alpha-induced protein 8-like 2 (TIPE2) possesses potent anti-inflammatory effect. However, if TIPE2 ameliorates sciatic nerve injury (SNI)-induced inflammation and pain remains undiscussed, the underlying role TAK1 in it were unknown. To verify our imagine, we performed SNI surgery, analyzed expression colocalization of spinal cord dorsal root neurons (DRG) by immunofluorescence staining western blot. And biological analysis, inflammatory factors, pathological...

During a pandemic, health care workers (HCWs) will be essential to the system response. This pre-pandemic study aimed extend previous research by assessing views, and intended behaviors of hospital HCWs in Beijing, China, regarding pandemic influenza. We undertook cross-sectional investigation sample from 24 hospitals China January 2009. The main outcome measures were intentions work attendance quarantine, antiviral use perceived preparation. Our found that most influenza very serious but...

Background: Four-dimensional flow magnetic resonance imaging (4D MRI) is a promising new technology with potential clinical value in hemodynamic quantification. Although an increasing number of articles on 4D MRI have been published over the past decades, few studies statistically analyzed these articles. In this study, we aimed to perform systematic and comprehensive bibliometric analysis explore current hotspots future directions. Methods: The Web Science Core Collection searched for...

Under the premise of ensuring network performance, ResNet proposes shortcut connections as basic structure to self-adjust depth converge identity map. This resolves performance degradation that occurs after number layers becomes deeper. Field Programmable Gate Array (FPGA) is a highly flexible hardware platform, which more convenient for deployment different neural structures. Therefore, this paper accelerates object detection algorithm based on FPGA platform. Firstly, ping-pong buffer...

Recently, a large number of visual tracking algorithms based on discriminative correlation filter have been proposed with demonstrated success. However, most cannot well handle long-term videos in which the locating error may accumulate and lead to drifting or failure. Hence, it is great importance design robust tracker can effectively alleviate drift redetect object case In this paper, continuous has achieve subpixel locations domain. For scale estimation, we present novel multipyramid...

Abstract Mn–Cu alloys are metal materials, which can be used to reduce vibration and noise from machines. With their inner damping mechanism, the show an excellent capacity. However, previous reports that capacity of often attenuates after placing at room temperature (RT) for a long time. In present study, as-cast Mn–Cu–Al–0∼3 wt% Sn were held RT 18 months. Their crystallization morphology was observed using backscattered electron (BSE) technology. The phase distribution characterized...

Constructing a trust network can provide strong foundation for realizing security in ubiquitous environments. This approach is inspired by social networks, which have two typical characteristics: small-world and scale-free properties. Small-world properties consist of high clustering short average path length. It often means that we easily find between any agents such an expected property networks. Another feather networks link distribution. The most notable characteristic power law...

Feature fusion is the process of combining information from different sources or feature sets into a more comprehensive informative set. crucial because it can help to synthesize levels features improve detection performance. In order address problem imbalance between semantic and positional due diversity object scales in real complex scenes, SSD algorithm selected as baseline study bi-directional pyramid structure based on path enhancement. This fully fuse deep maps shallow ones....

In the present study, ability of baicalin to relieve neuropathic pain due spinal nerve ligation in rats was explored, and relationship between α2-adrenoceptors (α2-AR) determined. The model established by ligating L5-L6 nerves Sprague-Dawley rats. Several α2-AR antagonists were injected into intramedullary sheath evaluate role pain. included nonselective antagonist idazoxan, α2a-AR BRL 44408, α2b-AR ARC 239 α2c-AR JP 1302. divided an untreated control group, saline group + groups. Paw...

The similarity degree of hand-written characters in engineering drawings is analyzed. On the basis results, a hierarchical neural network proposed for recognizing drawings. In memorizing and procedure distributed into several subnetworks. Experimental results are also given.

Direct volume rendering techniques use semi-transparency to visualize much more important features in the three-dimensional scalar sample volumes than isosurface methods. However, they are computationally expensive and far from interactive manipulation. In fact, on base of boundary representation scheme for volumetric data, 3D spatial coherence can be fully exploited drastically reduce time memory space arbitrary viewing orientation. A PC-based algorithm using is proposed this paper, which...

Trust relationships between agents provide a strong foundation for realizing security in ubiquitous computing environments. This approach is inspired by real-life networks. Furthermore, many studies show that networks have the ldquosmall-world phenomenonrdquo. Small-world are with high clustering and short average path length. These two properties often mean we can easily find any such networks, which an expected property of trust In this paper, based on existing small-world theories,...

Along with an increasingly wide utilization in the fields of ETC application, it becomes more and important to measuring quickly accurately on key equipment system, such as OBU RSU .This article is based requirement system propose a new design proposal by selecting STR715FR0 chip base core ARM7TDMI series 5.8GHz radio frequency transceiver circuit, actual operation test results show that DSRC device Measuring Instrument works stability, reliability low power consumption, which enables...

As a metal functional material, the Mn–Cu‐based alloys are regarded to be able cope with vibration and noise from machines.
