Authors: Su Hao , Liao Shan
Published: August 2014

Scene recognition is an important task for many computer vision and robotics applications. Recent progress in high-level object-based image representation has shown superior performance on scene classification tasks. In this work, we make an observation that groups of objects tend to co-occur frequently in a scene. We therefore propose to a novel framework that automatically learns object groups, and use them to build an image representation for scene recognition tasks. We model each object group as a template that explicitly encodes the spatial configurations of objects. To encourage the informativeness and discriminability, we learn the object group templates in a sparse filtering framework. Experiment results show that our object group representation could achieve state-of-the-art performance for both scene discovery and scene classification tasks.

Authors: Liu Kan Gong , Zhang Jian Pei , Yang Jing
Published: August 2014

The existing road network privacy protection models do not consider the density of the user and the road length. To solve this problem, we propose a Euclidean distance-based road network privacy protection model. First, we put the projection distance of sections in the road network context as the actual distance between two users located in this section. For users in different sections, we put the sum of distance with respect to the length of sections as the relative position between them. Secondly, combining traditional anonymity models and road network characteristics, we propose the road network (k, l)-anonymous model and design algorithms to implement it. Finally, we use the experimental verify performance of the algorithm. Theoretical analysis and experimental results show that the algorithm is correct and effective.

Authors: Lu Nan
Published: August 2014

This paper proposed a novel method to extract bilingual translation pairs from the web. Based on the observation that translation pairs tend to appear collectively on the web, a recursive process is used to extract high quality translation pairs from the web. First query the search engine with some seed data and crawl the returned pages. Then identify the Collective Translation Pair Block (CTPB) which contains the collective translation pairs using a heuristic evaluation method. After the CTPB has been identified, a PAT tree is employed to generate the extraction patterns automatically. Then a ranking SVM model is used to re-rank these patterns based on the F measure. The top 10 patterns are adopted to extract the translation pairs with the help of surface pattern. At last in order to get the high quality extraction translation, the extracted translation pairs are verified by a SVM classifier based on the translation relevant between the source and the target language.

Authors: Li Yan Long , Zhou Li Min
Published: August 2014

Abstract:Aim:We aimed to determine the effects of exhaustion exercise on HO-1 expression, the function of improving the sports ability and promoting the exercise induced fatigue in mice.Methods:Breeding, adaptively exercise BDF1 mice, 6 weeks age.They were randomly divided into normal saline control group,zinc protoporphyrin pharmacological inhibition group, the cobalt protoporphyrin drug induced group, HO-1 genetically modified group, each group was used for exhaustion exercise on the treadmill, and divided into immediate group and 24h after exhaustion groups.HO-1mRNA and protein, serum CK, BUN, urine protein were measured by using RT-PCR,Western-blot method, kinetic method, two point method and coomassie brilliant blue method. Results:The results indicated that HO-1mRNA expression increased after exhaustion exercise in the salinegroup, the other three groups changed little, HO-1 protein after exhaustion exercise of the saline group and drug inhibition group was higher than pre-exercise,24h after exercise obviously declined,24h after exhaustion exercise in drug induced group was higher than pre-exercise than immediately exercise.Exhaustion exercise time of the drug induced group(383.08±65.04min) and genetically modified mice(468.25±52.41min)was longer than the pharmacological inhibition (341.08±73.03min)and saline group(468.25±52.41min),significant variations were found in them(p<0.05). CK, BUN and urine protein removal were faster in drug induced group, the pharmacological inhibition of the group was slower. CK, BUN were faster in genetically modified group, but urine protein was in a higher level. Conclusion:Exhaustion exercise can induce skeletal muscle HO-1 expression of the wild type mice, it is not obvious in the higher HO-1 expression mice. Expression of HO-1 must be within limits, which can enhance mice exercise ability and promote the recovery of exercise fatigue.
IRE1a Negative Regulates Chondrocyte Differentiation
Authors: Guo Feng Jin , Xia Fei , Jiang Rong , Li Mei Ling
Published: August 2014

We present evidences demonstrating that overexpression of IRE1a inhibits chondrocyte differentiation, as revealed by reduced expression of Col,,SOX9, ColX, MMP-13, IHH, Runx2. Furthmore, IRE1a-mediated inhibition of chondrogenesis depends on its enzymatic activity, since its point mutant lacking enzymatic activity completely loses this activity. The RNase and Kinase domains of IRE1a C-terminal is necessary for its full enzymatic activity and inhibition of chondrocyte differentiation. Mechanism studies demonstrate that granulin-epithelin precursor (GEP),a growth factor known to stimulate chondrogenesis, induced IRE1a expression in chondrogenesis. In addition, IRE1a inhibits GEP-mediated chondrocyte differentiation as a negative regulator. Altered expression of IRE1a in chondrocyte hypertrophy was accompanied by altered levels of IHH and PTHrP.Collectively,IRE1a may be a novel regulator of chondrocyte differentiation by 1) inhibition GEP-mediated chondrocyte differentiation as a negative regulator; 2) promoting IHH/PTHrP signaling.

Saponins from Rhizoma Panacis Majoris (SRPM), the bioactive component in Rhizoma Panacis Majoris, were reported to possess protective effects on brain injury, but the underlying mechanisms remain poorly understood. This study was performed to investigate the protective effects and possible mechanism of SRPM on cerebral ischemia/reperfusion (CI/R) injury. Neuroprotective effects of SPRM in CI/R mice was evaluated by infarct size, biochemical values, Nuclear factor erythroid 2-related factor 2 (Nrf2) and Bcl-2 family expressions. In the study, we found that SRPM exerted beneficially protective effects on CI/R injury, mainly scavenging oxidative stress-triggered overgeneration and accumulation of reactive oxygen species, improving the Nrf2-mediated antioxidant response: role of Nrf2 and Bcl-2 family expressions, and alleviating CI/R injury and cerebral cell death.
