Frontiers of Medicine 2008, Volume 2, Issue 4,   Pages 391-395 doi: 10.1007/s11684-008-0075-1

Abstract: To study the effects of early signal substances induced by heat stress in brains of Kunming mice, six-month-oldmice ( = 72) were pretreated with heat stress and subsequent ischemia/reperfusion by clipping of theirdifferent treatments, animals were randomly divided into four groups: (1) normal control group; (2) heat stressfollowed by ischemia and reperfusion group (HS/IR); (3) ischemia and reperfusion group (IR); (4) heat stressThe results indicate that heat stress can induce CREB expression, which in turn stimulates CGRP secretion

Abstract: of static and dynamic stresses, which include two kinds of fault reactivations from: mining-inducedquasi-static stress (FRMSS)-dominated and seismic-based dynamic stress (FRSDS)-dominated.The results show that fault-induced coal burst is triggered by the superposition of high static stressin the fault pillar and dynamic stress from fault reactivation.High static stress comes from the interaction of the fault and the roof structure, and dynamic stress

Unified description of sand behavior

Feng ZHANG, Bin YE, Guanlin YE

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 2,   Pages 121-150 doi: 10.1007/s11709-011-0104-z

Abstract: In this paper, the mechanical behavior of sand, was systematically described and modeled with a elastoplastic model proposed by Zhang et al. [ ]. Without losing the generality of the sand, a specific sand called as Toyoura sand, a typical clean sand found in Japan, has been discussed in detail. In the model, the results of conventional triaxial tests of the sand under different loading and drainage conditions were simulated with a fixed set of material parameters. The model only employs eight parameters among which five parameters are the same as those used in Cam-clay model. Once the parameters are determined with the conventional drained triaxial compression tests and undrained triaxial cyclic loading tests, then they are fixed to uniquely describe the overall mechanical behaviors of the Toyoura sand, without changing the values of the eight parameters irrespective of what kind of the loadings or the drainage conditions may be. The capability of the model is discussed in a theoretical way.

Jingfa LIU, Fan LI, Ruoyao DING, Zi’ang LIU,jfliu@nuist.edu.cn,bj2014_lifan@163.com

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 8,   Pages 1189-1204 doi: 10.1631/FITEE.2100360

Abstract: At present, is a crucial method for obtaining effective domain knowledge from massive heterogeneous networks. For most current focused crawling technologies, there are some difficulties in obtaining high-quality crawling results. The main difficulties are the establishment of topic benchmark models, the assessment of topic relevance of hyperlinks, and the design of crawling strategies. In this paper, we use domain to build a topic benchmark model for a specific topic, and propose a novel multiple-filtering strategy based on local and global (MFSLG). A comprehensive method (CPEM) based on the web text and link structure is introduced to improve the computation precision of topic relevance for unvisited hyperlinks, and a (SA) method is used to avoid the falling into local optima of the search. By incorporating SA into the with MFSLG and CPEM for the first time, two novel strategies based on and SA (FCOSA), including FCOSA with only global (FCOSA_G) and FCOSA with both local and global (FCOSA_LG), are proposed to obtain topic-relevant webpages about s from the network. Experimental results show that the proposed crawlers outperform the other focused crawling strategies on different performance metric indices.
