In this paper, we develop a novel object tracking method based on sparse representation. First, we propose a relaxed sparse representation model, based on which the tracking problem is casted as an inverse sparse representation process. In this process, the target template is able to be sparsely approximated by all candidate samples. Second, we present an objective function that combines the sparse representation process of different fragments, the relaxed representation scheme and a weight reference prior. Based on some propositions, the proposed objective function can be solved by using an iteration algorithm. In addition, we design a tracking framework based on the proposed representation model and a simple online update manner. Finally, numerous experiments are conducted on some challenging sequences to compare our tracking method with some state-of-the-art ones. Both qualitative and quantitative results demonstrate that the proposed tracking method performs better than other competing algorithms.

We used the quantitative method to compare with Chinese junior middle school students' mathematics belief systems in Chaoxian and Han nationalities, and their correlations within its own group. By comparison, the results revealed that all students in Han and Chaoxian nationalities hold multiple beliefs, and their belief systems are not stable. In addition, there were some differences and similarities between their belief systems in two nationalities, and significant correlations were founded.

Investigation of an organic extract of the fruits Schisandra wilsoniana led to the isolation of two new highly oxygenated nortriterpenoids, named schilancidilactones V-W (1-2). Their structures were elucidated by spectroscopic evidence. Compounds 1-2 feature a double bond between C-7 and C-8 compared with related known nortriterpenoids isolated from the genus Schisandra. Compounds 1 and 2 were tested for their anti-HIV-1 activities and cytotoxicity. The results revealed that compounds 1 and 2 showed moderate anti-HIV-1 activities with $EC_{50}$ 3.05 and 2.87 ${\mu}g/mL$, respectively, and compound 1 showed high cytotoxicity against KB and MDA-MB-231 cell with $IC_{50}$ values of 3.18 and 5.22 ${\mu}M$, respectively.

In order to study the biological function of gapdh gene in yak, and prove whether the gapdh gene was a useful intra-reference gene that can be given an important role in molecular biology research of yak, the cDNA sequence encoding glyceraldehyde-3-phosphate dehydrogenase from yak was cloned by the RT-PCR method using gene specific PCR primers. The sequence results indicated that the cloned cDNA fragment (1,008 bp) contained a 1,002 bp open reading frame, encoding 333 amino acids (AAs) with a molecular mass of 35.753 kDa. The deduced amino acids sequence showed a high level of sequence identity to Bos Taurus (99.70%), Xenopus laevis (94.29%), Homo sapiens (97.01%), Mus musculus (97.90%) and Sus scrofa (98.20%). The expression of yak's gapdh gene in heart, spleen, kidney and brain tissues was also detected; the results showed that the gapdh gene was expressed in all these tissues. Further analysis of yak GAPDH amino acid sequence implied that it contained a complete glyceraldehyde-3-phosphate dehydrogenase active site (ASCTTNCL) which ranged from 148 to 155 amino acid residues. It also contained two conserved domains, a NAD binding domain in its N-terminal and a complete catalytic domain of sugar transport in its C-terminal. The phylogenetic analysis showed that yak and Bos taurus were the closest species. The prediction of secondary structures indicated that GAPDH of yak had a similar secondary structure to other isolated GAPDH. The results of this study suggested that the gapdh gene of yak was similar to other species and could be used as the intra-reference to analyze the expression of other genes in yak.

The aim of this article is to critically review the PRC's policies related to its minority nationalities with a special emphasis on the identification of minority nationalities(minzuzhibie) and the establishment of minority nationality autonomous regions(minzuzizhiquyu), as a part of national integration Process. In that Process, the intentional application of the criteria on nationality identification, the establishment of minority nationality autonomous regions, the population redistribution policies and the gerrymandering by the government played an important role in the deconstruction of traditional basis of identities and the territorialization of ethnicity. The goals of government have been the redefinition of 'Chinese', the the invention of 'Chinese nationality(zhongguominzu or zhonghuaminzu)'and the unification of its national territory. However, these have led to the unexpected result by creating the new ethnic-territorial identities along with the nationalities identified and the territories defined by the government.

The objective of this study was to determine the effect of forage: concentrate ratio (F:C) on growth performance, ruminal fermentation and blood metabolites of housing-feeding yaks. Thirty-two Maiwa male yaks (initial body weight = $207.99{\pm}3.31kg$) were randomly assigned to four dietary treatments (8 yaks per treatment). Experimental diets were: A, B, C, D which contained 70:30, 60:40, 50:50 and 40:60 F:C ratios, respectively. Dry matter intake and average daily gain in yaks fed the C and D diets were greater (p<0.05) than yaks fed the A and B diets. No differences were found in ruminal $NH_3-N$, total volatile fatty acids, acetate, butyrate, valerate, and isovalerate concentrations. The propionate concentration was increased (p<0.05) in the C and D groups compared with the A and B diets. In contrast, the acetate to propionate ratio was decreased and was lowest (p<0.05) in the C group relative to the A and B diets, but was similar with the D group. For blood metabolites, no differences were found in serum concentrations of urea-N, albumin, triglyceride, cholesterol, low density lipoprotein, alanine aminotransferase, and aspartate aminotransferase (p>0.05) among treatments. Treatment C had a higher concentration of total protein and high density lipoprotein (p<0.05) than A and B groups. In addition, there was a trend that the globulin concentration of A group was lower than other treatments (p = 0.079). Results from this study suggest that increasing the level of concentrate from 30% to 50% exerted a positive effect on growth performance, rumen fermentation and blood metabolites in yaks.

Superoxide dismutases (SODs) constitute the first line of cellular defense against oxidative stress in plants. SODs generally occur in three different forms with Cu/Zn, Fe, or Mn as prosthetic metals. We cloned the full-length cDNA of the Thellungiella halophila Cu/Zn-SOD gene ThCSD using degenerate RT-PCR and rapid amplification of cDNA ends (RACE). Sequence analysis indicated that the ThCSD gene (GenBank accession number EF405867) had an open reading frame of 456 bp. The deduced 152-amino acid polypeptide had a predicted molecular weight of 15.1 kDa, an estimated pI of 5.4, and a putative Cu/Zn-binding site. Recombinant ThCSD protein was expressed in Escherichia coli and assayed for SOD enzymatic activity in a native polyacrylamide gel. The SOD activity of ThCSD was inactivated by potassium cyanide and hydrogen peroxide but not by sodium azide, confirming that ThCSD is a Cu/Zn-SOD. Northern blotting demonstrated that ThCSD is expressed in roots, stems, and leaves. ThCSD mRNA levels increased by about 30-fold when plants were treated with sodium chloride (NaCl), abscisic acid (ABA), and indole-acetic acid (IAA) and by about 50-fold when treated with UVB light. These results indicate that ThCSD is involved in physiological pathways activated by a variety of environmental conditions.

The second-order scattering (SOS) phenomenon of the interaction of Pd nanoparticles with protein was reported and a simple, sensitive, palladium nanoparticle-based assay for trace amount of protein with SOS technique was developed. The SOS intensities were significantly enhanced due to the interaction of Pd nanoparticles with bovine serum albumin (BSA) or human serum albumin (HSA) at pH 3.5 or 4.0, respectively. The maximum SOS peak appeared at 260/520 nm (λex/λem). The optimal experiment conditions, affecting factors and the influence of some coexisting substances were checked. The SOS intensity increased proportionally with the increase of Pd concentration below 3.0 × 10?5 mol·L?1, while declined gradually above 4.0 × 10?5 mol·L?1. BSA within the range of 0.01-2.6 μg·mL?1 and HSA of 0.01-1.7 μg·mL?1 can be detected with this method and the detection limits were 2.3 and 11.2 ng·mL?1, respectively. The method was successfully applied to the quantitative detection of total protein content in human serum samples with the maximum relative standard deviation (RSD) lower than 2.6% and the recoveries over the range of 99.5-100.5%.

The Xinjiang Uighur Autonomous Region to from the most of Eastern turkistan is located at North-wetern part of China, and it is the center to form the famous silk-road historically. In th exinjiang Uighur Autonomous Region there are 47 nationalities. In this study, the researcher studied the historical background, and the traditional culture about dress sand ornaments of 4 nationalities (that is Uighur, Kazakh, Kirgiz and Tajik). The results of the present study are as follows : In the basic structure of traditional costume by races, there is not big difference. Then , in men , the trousers and the shirts of funic type become the basis with the style which is convenient to act. And , to wear vest , or jacket , or chanban, over it makes a little difference . In women also, same structure shows with the form to wear vest or outerwear, on the basis of one piece. But , in a small hat, heat wear, color contrast, and decoration element etc. , strict difference is showing. After all, they show very similar clothing life culture basically in natural environment, religion , and life habit etc. But, the discrimination is made in the detailed side. So , it can be said that they show the conservative nature of nationalities, and have preserved the unigue identity of their own culture.
