＜正＞The topic of automated assembly is widely addressed by the robotics communities. however, so far there is no systematic framework to assist the construction of an intelligent robot control system. Even systems so called intelligent systems are not truly intelligent when they are compared to human. It is therefore essential to define and analyse the necessary intelligence criteria that an intelligent robot should posses. Such criteria are then implemented on an appropriate control platform so as to enhance the intelligence of the robot. As such, one of the principal aims of this paper is to discuss and identify the criteria of machine intelligence that are central to achieving an intelligent robot. With these criteria as basis, the paper then presents an intelligent framework that is based on the stochastic hidden Markov model （hMM）. This framework consists of a number of functional blocks for the design and implementation of an intelligent robot control system. Each functional block is responsible for a corresponding feature with specific intelligent capabilities. The paper starts with a review of the applications of hMM in automated assembly, which is followed by the description of the main features and architecture of the proposed framework.

＜正＞ Livestock manure applied to land is a traditional method of both manure disposal and providing nutrients for crop production. Subsurface injection of liquid manure is generally recommended to both control odor and reduce nutrient losses by volatilization of ammonia. There are many different types of injection equipment on the market. Producers need energy input information to make informed decisions on selection of appropriate injection systems for their particular farm. The objectives of this study were to compare energy inputs for different types of injection equipment under different soil and crop residue conditions.

Variable range hopping conduction in n-CdSe samples at very low temperature

Journal of Semiconductors 2015年第12期36卷 14-17页

作者： M Errai A El Kaaouachi h El Idrissi Physics Department Ibn Zohr University Faculty of Sciences Laboratoire Electronique électrotechnique Automatique et Traitement de l'Information Département Génie ElectriqueFaculté des Sciences et Techniques de Mohammedia Université Hassan Ⅱ Mohammedia Casablanca

We reanalyzed experimental data already published in Friedman J R, Zhang y, Dai P, et al. Phys Rev b, 1996, 53（15）： 9528. Variable range hopping （VRh） conduction in the insulating three-dimensional n-CdSe samples has been studied over the entire temperature range from 0.03 to 1 K. In the absence of a magnetic field, the low temperature conductivity a of the three samples （A, b and C） obeys the Mott VRh conduction with an appropriate temperature dependence in the prefactor （a = σ0 exp [- （T0/T）]^p with p ≈ 0.25）. This b.h.vior can be explained by a VRh model where the transport occurs by hopping between localized states in the vicinity of the Fermi level, EF, without creation of the Coulomb gap （CG）. On the contrary, no Efros-Shklovskii VRh is observed, suggesting that the density is constant in the vicinity of the EF.

Correlation of chromosomal polysomy with overexpression of c-myc and c-erbb-2 in primary nasopharyngeal carcinoma: Tissue microarray study

Chinese Science bulletin 2002年第3期47卷 217-220页

Many genes may be involved in nasopharyn-geal carcinoma (NPC) development and progression. Several known oncogenes, including c-myc and c-erb-b2, have been shown to have structural alteration and aberrant expression in NPC. here, we constructed a tissue microarray to deter-mine the status of c-myc and c-erbb-2 oncogenes at the DNA and protein levels using interphase fluorescence in situ hy-bridization (FISh) and immunohistochemistry (IhC) and to define the diagnostic, prognostic importance of the genetic changes. Results showed that amplification of c-myc and c-erbb-2 was not found in NPC. Polysemy 8 and 17 were observed in 43%-50% and 20%-27% of NPC tumors, respectively. Overexpressions of c-myc and c-erbb-2 onco-proteins were detected in 53.6% and 54.5% cases of NPC with polysomy 8 and 17, respectively. There was no signifi-cant correlation between c-myc and c-erbb-2 staining and the clinical stage. but overexpression of c-erbb-2 was associ-ated with polysemy 17 in NPC. These findings suggest that

Forest Research Institute Malaysia （FRIM） Kepong 52109 Kuala LumpurMalaysia Plant biotechnology Laboratory School of Bioscience and Biotechnology Faculty of Science and Technology Universiti Kebangsaan Malaysia 43600 UKM-Bangi Malaysia Forest Research Institute Malaysia （FRIM） Kepong 52109 Kuala LumpurMalaysia Forest Research Institute Malaysia （FRIM） Kepong 52109 Kuala LumpurMalaysia

＜正＞ Teak （Tectona grandis） provides one of the most highly sought after timber in the world and is a widely recommended species for reforestation. As such teak is widely planted in Malaysia. Though no serious outbreaks have been recorded for teak in Malaysia, but insect attack remains the most important threat to the timber industry. Thus, in efforts to overcome the problem, an integrated pest management system needs to be developed. Spray.ng of commercial bt has been a common practice in addressing minor outbreaks. however, one of the main limitations of the spray.ng technique is poor coverage, especially on plant surfaces. Poor coverage, however, could be overcome by planting insect resistant trees. In addition, the approach of using genetic engineering in addressing the above problem proves to be possible with the advancement made in genetic transformation of trees especially in the last decade. This, together with improved knowledge on gene function following improved DNA recombinant techniques promises the major advancement in pest management of forest species. This report demonstrates the possibility of transferring foreign gene into teak cells. In this study, nodal segments of teak were subjected to particle bombardment. Nodal segments bombarded with gold particles coated with plasmid DNA carry.ng hygromycin phosphotransferase （hpt）, β-glucuronidase （gus） and cry1A（b） genes were then transferred onto medium for shoot development. The shoots were than transferred onto the same medium supplemented with 10mg/L hygromycin for selection. Selection was repeated several times with six-week subculture intervals on the same hm-containing media. The presence of the transgenes in the hmr plants was confirmed using PCR.

近几十年来俄罗斯汉学界对汉语结构及其发展方向的看法可分为两派。前者确认汉语的“词汇性”,即“以词为主”的发展方向。这个概念框架体系意味着,如果说其他体系的语言通过语法手段来表现一切,汉语及其他的孤立语则是借助于词(或是类似于词的物质单位)来表现。后者的观点则恰恰相反,认为汉语在远古的某个时期失去了旧形态并获得了另一些特征,在此基础上汉语开始被界定为单音节的、词根的、无形态语(这里须指出。
