In the paper a careful error analysis for the quasi-conforming and generalized conforming elements is given. It is shown that the consistency error due to nonconformity of the two unconventional elements is of order O(h^2), one order high than that of other conventional nonconforming elements with nine parameters.展开更多

Information is an integral part of the Universe. By its physical essence information is heterogeneity of matter and energy. The universal measure of physical heterogeneity of information is the Shannon in- formation entropy. It is important to note that the Neumann entropy cannot be applied as the universal measure of het- erogeneity because it is equal to zero for structured pure state. Therefore information is inseparably connected with matter and energy. The informatics laws of nature are: the basic law of Zeilinger’s quantum mechanics postulates that the elementary physical system (in particular, fundamental particles: quarks, leptons,…) bears one bit of information, the law of simplicity of complex systems, the law of uncertainty (information) conservation, the law of finiteness of complex systems characteristics, the law of necessary variety by W. Ashby, and the theorem of K. Gödel. The law of finiteness of complex systems characteristics and the principle of necessary variety by W. Ashby impose restrictions on the topology and symmetry of the universe. The author’s works testify about the practicality of information laws simultaneously with physical rules for cognition of the Universe. The results presented in this paper show the effectiveness of informational approach to studying the black holes. The article discusses the following questions: The volume of information in the black hole, Emission and absorption of usual substance by a black hole, Formation and development (changing) of black holes, Black hole merger. Black hole is called optimal if information content is minimal at the University region. Optimal black holes can exist when at least the two types of substance are available in the Universe: with non-linear and linear correspondence between information content and mass.

Hawking showed that particle-antiparticle pairs generated at the event horizon—the outer periphery of a black hole—would be separated. One particle would fall into the black hole while the other would escape, making the black hole a radiating body. Characteristics of the emission and absorption of usual substance by a black hole can be described by information models. Estimation of the volume of information in black holes is necessary for generation of restrictions for their formation, development and interconversion. Information is an integral part of the Universe. By its physical essence information is heterogeneity of matter and energy. Therefore information is inseparably connected with matter and energy. An information approach along with a physical one allows to obtain new, sometimes more general data in relation to data obtained on the ground of physical rules only. The author’s works, testify about the practicality of information laws usage simultaneously with physical rules for cognition of the Universe. The results presented in this paper show the effectiveness of informational approach for studying the black holes. The article discusses the following questions: The volume of information in the black hole;Information model of a black hole;Characteristics of the emission and absorption of usual substance by a black hole describes the information model of a black hole;The information paradox;A simple explanation of the information paradox by the information model of a black hole.展开更多

Efficacy and safety information were assessed at one year follow-up. The relapse rate was similar in both groups after 12 months followed up (7% and 5%). The withdraw rate was significant lower in CM group compared with CAU group (10% and 36%). <strong>Results</strong>: There is no significant difference in PANSS, PSP and SSMI score between 2 groups at each visit. Between endpoint and baseline, there is a significant improvement on PANSS negative score and PSP in patients treated with CM, while CAU group was not significantly changed. <strong>Conclusions</strong>: There is a possible effectiveness of CM group of improving negative symptoms and social function in schizophrenia clients.展开更多

Objective： To investigate the biological differences between UIM, HIM and intestinal type gastric cancer （IGC）, a panel of biomarkers were detected. Methods： A total of 38 cases of IGC, 41 HIM and 56 UIM adjacent to gastric cancer were studied. Immunohistochemistry was used to detect the expressions of pS2, MUC2, MUC5AC, MUC6, Ki-67, EGFR, p53 and sulfo-Lewisa in UIM, HIM and IGC. Microsatellite instability （MSI） in UIM, HIM and IGC was detected by using Denaturing High Performance Liquid Chromatography （DHPLC）. Results： The pS2 antigen expression in UIM （78.6%） was significantly higher than in HIM and IGC （9.8%, 10.5%）, p〈0.01. The MUC6, sulfo-Lewisa and EGFR protein expressions were significant increased in HIM （24.4%, 82.9%, 48.7%） and IGC （34.2%, 75.0%, 42.1%） than in UIM （3.6%, 25.5%, 17.9%）, p〈0.01. A reversed pattern of expressions of MUC2 and MUC5AC was observed in UIM （96.4%, 50.0%） and HIM （82.9%, 36.6%） compared with IGC （52.6%, 13.2%）, p〈0.05; and the p53 gene expression was increased from UIM （1.8%） to HIM （19.5%） to IGC （57.9%）, p〈0.01. The Ki-67 labeling index was significantiy different among three lesions （UIM： 16%±6%, HIM： 45%±9%, IGC： 63%±10%, p〈0.01）. Conclusion： These findings suggest that there are different bio-characteristics among UIM, HIM and IGC, and HIM may have higher potential to progress to more advanced lesions in comparison with UIM.展开更多

Here, we factorize the ground stateout of the Hamiltonian H in order to get the new operatorwhich preserves some spaces of polynomialsin the case of equal masses, i.e. (the usual Calogero model) and in the case with different masses. The spectrum of these both cases is found easily.
