The magnitude distribution of the long range correlation which can be reflected by the mutual information is PS〉PSa〉PSb (P5a and P5b are the sequences that replace solely Alu repeats and all interspersed repeats with random uneorrelated sequences in human Y chromosome palindrome 5, respectively); and the magnitude distribution of the short range correlation which can be reflected by the n-tuple entropy and the conditional entropy is PS〉P5a〉PSb〉random uncorrelated sequence. In other words, when the Alu repeats and all interspersed repeats replace with random uneorrelated sequence, the long range and short range correlation decrease gradually. However, the random nncorrelated sequence has no correlation. This research indicates that more repeat sequences result in stronger correlation between bases in human Y chromosome. The analyses may be helpful to understand the special structures of human Y chromosome palindromes profoundly.展开更多

The context query is based on a resource description framework (RDF) dataset and SPARQL language. To discover collaborative associations, an approach of transforming RDF named graphs into "context graph" is proposed. First, the definitions of the importance of the nodes and the weight assignment for the "context graph" are given. Secondly, the implementation of a spread activation algorithm based on "context graph" is proposed. An infrastructure is also built up in the collaborative context space (CCS) system to support context memory and knowledge discovery in a collaborative environment.展开更多

Owing to its distinctive features, the Internet language draws extensive attention and evokes dispute. Should we make laws to restrict its development or be magnanimous and tolerant? The present authors think that the dispute reflects the clash between the traditional culture and the "fast food" culture. The two cultures would co-exist harmoniously and co-develop healthily only if we cherish the law in the development of language and grasp the indirect correlation between them.展开更多

Methods: A total of 148 patients hospitalized for HF compensation were analyzed from April 1 to December 31, 2017 in a tertiary referral hospital for cardiovascular diseases. The diagnosis of anemia was established according to the Brazilian Ministry of Health criteria, considering a serum hemoglobin value of 〈 13 g/alL for men and 〈 12 g/dL for women. Data were collected through medical and physical attendance records. Statistical analysis was performed using the Epi Info program, version 7.0 for Windows, with Student' s t test for unpaired variables, Chi-square test and Fischer test. The significance ofp 〈 0.05 was considered. Results: Of the 148 selected patients, 63.5% were male, 60.1% were over 65 years old, 50.74% were enrolled in the first grade, and 93.2% were self-declared white. The prevalence of anemia observed in the study population was 72 (56.25%), of which 49 (68%) were male and 23 (32%) were female. The mortality rate of the anemic patients was 19.4%, a total of 14 patients, whereas the non-anemic patients rate was 7.9%. It was observed that patients with worse outcome had hemoglobin 〈 12rag/alL (p = 0.045) and Functional Class (FC IV) by the New York Heart Association (NYHA) (p = 0.0001) at hospital admission. Conclusions: It is noticed that anemia is a frequent finding in patients with HF and that it interferes in the clinical manifestations, with worsening of the prognosis. Anemia treatment is not yet standarized in the HF approach, but patients without anemia appear to evolve with more favorable outcomes than anemia.展开更多

Most of the nighttime cloudy occurred from February to July, which is related to the rainy season in the area of the observatory. The best period to run optical observations over Sao Joao do Cariri starts in the early night up to 22:00 LT (Local Time) throughout the period between August and December. An anti-correlation between the F10.7 cm solar flux index and the number of cloudy nights was observed, which is an evidence of the cosmic rays activity in the lower earth's atmosphere. The location of the all-sky imager provides reliable optical observations all year through.展开更多

According to relevance theory, every act of ostensive communication communicates a presumption of its own optimal relevance. The communicator, who is aiming at optimal relevance, must direct the audience to a particular set of assumptions by using discourse markers. Whereas, from the audience's point of view, discourse markers can minimize his contextual assumptions in looking for relevance, thus the pragmatic inferential process will be much easier.展开更多

In the key generating procedure, the algorithm generates a plaintext-dependent secret keys set. In the encryption process, the diffusion operation with cipher output feedback is introduced. Thus, cipher-irmge is sensitive to both initial keys and plaintext through only one round diffusion operation. The key space is large. As a resuk, the algorithm can effectively resist differential attacks, statistical attacks, brute-force attacks, known plaintext and chosen plaintext attacks. Perforrmnce test and security analysis demonstrates that this algorithm is eficient and reliable, with high potential to be adopted for secure comnmnications.展开更多

Gustav Klimt interprets this motif in a very personal manner, which throws a totally different light on the status of the knight than traditional interpretations. The aim of this paper is to indicate and analyze the very features that make Klimt's knight different from that established through the historic, literary, and artistic canons and reveal it as closer to Nietzsche's modern man--afflicted by the malady that the philosopher diagnoses and whose symptoms he describes as follows: A weakened personality, and the absence of a strong will, associated with the specific age and culture.展开更多

One of the few exceptions in this scenario is the attempt of Axel Honneth to connect the category of recognition to the original idea of the critical theory, without depriving it of his theoretical pregnancy, but at the same time eliminating his premises of philosophy of history. This study will start from the Honneth's reading of the first critical theory to analyze, secondly, the limits individualized by Honneth from the Habermas' sociological perspective, particularly those referred to his two levels model of society. The study will finally analyze the actuality of the category of recognition in relation to three problematic spheres: the cultural pluralism, the normativism, the connection between political philosophy and social theory.展开更多

文摘On the basis of information theory and statistical methods, we use mutual information, n- tuple entropy and conditional entropy, combined with biological characteristics, to analyze the long range correlation and short range correlation in human Y chromosome palindromes. The magnitude distribution of the long range correlation which can be reflected by the mutual information is PS〉PSa〉PSb (P5a and P5b are the sequences that replace solely Alu repeats and all interspersed repeats with random uneorrelated sequences in human Y chromosome palindrome 5, respectively); and the magnitude distribution of the short range correlation which can be reflected by the n-tuple entropy and the conditional entropy is PS〉P5a〉PSb〉random uncorrelated sequence. In other words, when the Alu repeats and all interspersed repeats replace with random uneorrelated sequence, the long range and short range correlation decrease gradually. However, the random nncorrelated sequence has no correlation. This research indicates that more repeat sequences result in stronger correlation between bases in human Y chromosome. The analyses may be helpful to understand the special structures of human Y chromosome palindromes profoundly.
