We review pseudo-relevance feedback as a mechanism for expanding short texts. Where short texts exhibit evolving concepts, topics and other characteristics, Web-based feedback systems were touted as the most ideal way of enriching the feature space of short texts. However, we note from a recent implementation of a Web-based pseudo-relevance feedback that it would only perform well under clinical situations...
Objective To evaluate the efficacy of artificial liver support system (ALSS) in the treatment of liver failure patients. Methods This is a multi-center, controlled, large sample clinic trial. 916 patients with liver failure from 6 hospitals were studied and followed. All the patients received similar pharmacological manipulation according to one and the same protocol but were divided into an ALSS...
Frame theory plays an important role in signal processing, image processing, data compression and sampling theory. In this short paper, some properties of Bessel sequences in Hilbert spaces are obtained, which generalize the existing results of frame to the case of Bessel sequences.
Ferro ferric oxide(Fe3O4) nanoparticles have found application as contrast agents for magnetic resonance imaging and as targeted delivery of drugs. Their stabilization as carrier systems remains a problem. The cytotoxicity of vascular endothelial cells induced by uncoated Ferro ferric oxide nanoparticles were investigated in this study. EA.hy926 cells were incubated with fresh medium containing uncoated...
After the bone meal was fermented by lactobacillus at different temperature, time, inoculation volume and bone concentration, the TCA-NSI and PTA-SN were investigated. Then, orthogonal experiments were adopted to analyze the effect of each factor according to single factor experiment. The results showed that the fermentation conditions were optimum at 36°C of fermentation temperature, 24h of fermentation...
This thesis mainly study the problem of the accuracy and optimization of the feature extraction on the points of interest in images. Due to the complexity of the image and the interference of noise in the image, the traditional feature extraction algorithm based on the points of interest is difficult to extract the information which users interested in. In order to solve the above problems, an improved...
Using a model of rat gastric ulcer to check the changes of trefoil factor family 2 (TFF2) and epidermal growth factor(EGF) in gastric mucosa during healing of experimental gastric ulcer. Rats gastric ulceration were caused by injection acetic acid to submucosa of gastric anterior wall. TFF2, EGF peptide were localized by the immunohistochemistry (IHC), and semi-quantitation analyzed with the integrated...
Integrating three-phase induction motor electromagnetic calculation program and multi-objective inverse optimization algorithm, a multi-objective & inverse three-phase induction motor optimization system with C++ is realized. This system can optimal design three-phase induction motor automatically. The design examples verify the effectiveness of the system.
PZ-30 excavator is a small tonnage miniature excavator. Due to the need of working condition, this machine should be long-term mount hydraulic breaking hammer. In order to reduce the damage on excavator boom caused by vibration and optimize the design of boom, it is needed to conduct modal analysis of boom. This paper uses the Algor finite element simulation software, combined with the actual working...
An efficient channelized structure of digital channelized receiver is derived and given in order to save a lot of resources of FPGA. The actual system is designed and CORDIC algorithm is adopted to realize the extraction of signal envelope and instantaneous phase and first order phase difference algorithm is used to realize instantaneous frequency measurement. The efficient channelized structure is...
The coupling effect of remanufacturing production corporations in the remanufacturing services supply chain can make the whole system producing accumulation effect. In order to improve the remanufacturing supply chain service quality and the competition ability, equivalent quality model is used in this paper. By introducing process capability and quality angle, the equivalent quality model can rationally...
The Grey Relation Analysis (GRA) with weight is presented in this paper. Specifically, the inhomogeneous weights-making model based on Data Envelopment Analysis (DEA) is introduced, which can overcome the regret between subjective values and homogenization evaluation. Through the cost-effectiveness on input and output index analysis of Institution of Higher Educations (IHEs), the evaluation index...
Microbial biofilms are encountered in a wide variety of applications, especially in wastewater treatment systems. Biofilm dynamics in wastewater treatment has been paid much attention, and the simulation of the biofilm growth has been studied with many approaches in recent years. To simulate the real microbial biofilm growth, this paper proposed the confined diffusion limited aggregation (DLA) models...
During the past two decades, Chinese clothing industry has made remarkable progress in production and export. China has become the world's largest clothing producer and exporter. However, it still falls behind traditionally strong competitors like Italia in term of quality and unit price. Based on industry research on international competitiveness, this paper first constructs an evaluation index system...
This paper presents a novel automatic air purification and adjusting device, it can purify and disinfect air using ozone water, absorb harmful gases, absorb carbon dioxide using absorbing liquid, purify air by plant root, realize the indoor temperature adjustment by natural water and without refrigerant such as Freon. We can solve the cross contamination and secondary pollution problem of normal air...
In order to analyze the data rationally in the process of teaching study, some statistical methods are used in this paper. By introducing descriptive statistics, parametric hypothesis test, one-way analysis of variances (ANOVA) and correlation analysis, the problem of data analysis in practice can be rationally solved. For illustration, some practical cases are utilized. And the result shows that...
Cell adhesion is implicated in a number of biological pathways such as angiogenesis, arteriosclerosis, chronic inflammatory diseases, and carcinogenesis. Chemokine receptor CXCR4 is often found aberrantly expressed on metastatic tumor cells. To investigate CXCR4 signaling in tumor cell adhesion, we stably overexpressed CXCR4 in hepatocellular carcinoma HepG2 cells. Regulation of CXCR4 in HepG2 cell...
This study explores students' continuance intention in e-learning education system by synthesizing Bhattacherjee's IS continuance theory as basis with the unified theory of acceptance and use of technology (UTAUT), and innovation diffusion theory. The integrated model was empirically tested with 180 bachelor students who had the experience of using the e-learning education system. The results indicate...
Most traditional epidemiological studies are based on the statistical analysis rather than spatial information. Therefore, the study combining spatial analysis with epidemiology is a promising and perspective field. This paper, based on the technology of GIS, the method of disease mapping and traditional statistics, is focus on the spatial data of influenza A virus subtype H1N1. A spatial database...
