Abstract:
We report model calculations of the time-dependent internal energy and entropy for a single quasi-free massive quantum particle at a constant temperature. We show that the whole process started from a fully coherent quantum state to thermodynamic equilibrium can be understood, based on statistics of diffracted matter waves. As a result of thermal interaction between the particle and its surroundings, the motion of the particle shows new feature.

Abstract:
The time-dependent entropy of a single free quantum particle in the non-relativistic regime is studied in detail for the process started from a fully coherent quantum state to thermodynamic equilibrium with its surroundings at a finite temperature. It is shown that the entropy at the end of the process converges to a universal constant, as a result of thermal interaction.

Abstract:
Protein structure prediction is one of the most important problems in computational biology. The most successful computational approach, also called template-based modeling, identifies templates with solved crystal structures for the query proteins and constructs three dimensional models based on sequence/structure alignments. Although substantial effort has been made to improve protein sequence alignment, the accuracy of alignments between distantly related proteins is still unsatisfactory. In this thesis, I will introduce a number of statistical machine learning methods to build accurate alignments between a protein sequence and its template structures, especially for proteins having only distantly related templates. For a protein with only one good template, we develop a regression-tree based Conditional Random Fields (CRF) model for pairwise protein sequence/structure alignment. By learning a nonlinear threading scoring function, we are able to leverage the correlation among different sequence and structural features. We also introduce an information-theoretic measure to guide the learning algorithm to better exploit the structural features for low-homology proteins with little evolutionary information in their sequence profile. For a protein with multiple good templates, we design a probabilistic consistency approach to thread the protein to all templates simultaneously. By minimizing the discordance between the pairwise alignments of the protein and templates, we are able to construct a multiple sequence/structure alignment, which leads to better structure predictions than any single-template based prediction.

Abstract:
The new accounting standards have been put into effect first in listed companies. It introduces new concepts as well as different processing methods which absolutely will have a great effect on listed companies’ performance. This effect includes three directions: (a) it will affect items on listed companies’ income statement in a direct way;(b) it will affect investors’ judgements of listed companies’ performance; (c) it will introduce some other methods of controlling earnings of managers. This paper analyzes these effects and at last comes to the conclusion that the new accounting standards is much more precise than the last one in formulation, and covers more to details, which will restricts accounting control of earnings more effectively. Key words: The new accounting standards, Performance of listed companies, Financial indicators, Control of earnings

Abstract:
Objective: To study the correlation of blood stasis syndrome or its accompanied syndromes with Gensini score in patients with coronary heart disease (CHD) in stable condition.Methods: The syndrome types of traditional Chinese medicine (TCM) and blood stasis score in 131 CHD patients confirmed by coronary angiography were recorded. Gensini score was calculated according to the coronary pathological characteristics showed by angiography. The correlations of blood stasis syndrome and its accompanied syndromes with coronary lesion and Gensini score were analyzed.Results: Among the TCM syndrome types, blood stasis, turbid phlegm and qi deficiency were the most common syndromes, revealed in 85 patients (64.9%), 83 patients (63.4%) and 85 patients (64.9%), respectively. The coronary lesion length and Gensini score in the patients with blood stasis syndrome were much higher than those in the patients with non-blood stasis syndrome (P＜0.05 or P＜0.01). In the subtypes of blood stasis, the coronary lesion length and Gensini score in the patients with blood stasis accompanied by turbid phlegm syndrome were higher than those in the patients with non-blood stasis syndrome (P＜0.05). And in the patients whose blood stasis syndrome score was more than 9 points, the coronary lesion length was higher than that in the patients whose blood stasis syndrome score was less than 9 points (P＜0.05). Besides, with bivariate analysis, the blood stasis syndrome score showed no correlation with Gensini score (Pearson correlation coefficient was 0.104, P=0.241).Conclusion: Blood stasis syndrome is the most common TCM syndrome in CHD patients in stable condition. The blood stasis syndrome score is proportional to coronary lesion length, and reflects the severity of coronary lesion.

Abstract:
In this paper, we introduce a new approximation scheme based on the extragradient method and viscosity method for finding a common element of the set of solutions of the set of fixed points of a nonexpansive mapping and the set of the variational inequality for a monotone, Lipschitz continuous mapping. We obtain a strong convergence theorem for the sequences generated by these processes in Hilbert spaces as follows: Let C be a nonempty closed convex subset of a real Hilbert space H. Let A be a monotone and k-Lipschitz continuous mapping of C into H. Let S be a nonexpansive mapping of C into H such that , where and , respectively, denote the set of fixed point of S and the solution set of a variational inequality. Let f be a contraction of H into itself and and be sequences generated by for every n=1,2,…, where and are sequences of numbers satisfying and and . Then, and converge strongly to The results in this paper improve some well-known results in the literature.
