Recently, Internet is changing to a more social space in which all users can provide their contributions and opinions to others via websites, social networks or blogs. Accordingly, content generation within social webs has also evolved. Users of social news sites make public links to news stories, so that every user can comment them or other users’ comments related to the stories. In these site...

The method of functional integral bosonization is extended to examine the transmission properties of semi-infinite nanowires. In particular, it is shown that edge states will arise at the end point of the dimerized semi-infinite spin-chain and by combining the method of image and the bosonization technique, the system can be properly bosonized. Based on the bosonized action and a renormalizatio...

In traditional database applications the structure of data is pre-deened, and data are entered into the database specifying the schema element (relation or class, depending on the paradigm) they belong to. New emerging database applications, expecially those related to the Web, are characterized by data that have an irregular, heterogeneous, partial structure that quickly evolves. In this paper...

Gene networks describe functional pathways in a given cell or tissue, representing processes such as metabolism, gene expression regulation, protein or RNA transport. Thus, learning gene network is a crucial problem in the post genome era. Most existing works learn gene networks by assuming one gene provokes the expression of another gene directly leading to an over-simplified model. In this pa...

Semi-supervised support vector machines (S3VMs) are a kind of popular approaches which try to improve learning performance by exploiting unlabeled data. Though S3VMs have been found helpful in many situations, they may degenerate performance and the resultant generalization ability may be even worse than using the labeled data only. In this paper, we try to reduce the chance of performance dege...

In this paper we take an important step towards completely unsupervised stemming by giving a scheme for semi supervised stemming. The input to the system is a list of word forms and suffixes. The motivation of the work comes from the need to create a root or stem identifier for a language that has electronic corpora and some elementary linguistic work in the form of, say, suffix list. The scope...

Bad writing prospers in the humanities and social sciences, so we are spoilt for examples. In one famous case, Martha Nussbaum rounded on Judith Butler for her obscurity, arguing it was an insidious form of stylistic collaboration with the power structures targeted by her writings. Nussbaum’s review, ‘The Professor of Parody,’ raised the profile of a sentence already legendary as a result of Bu...

With rising trading volumes in securities transactions and increasing risks faced by global financial firms and markets, STP (Straight Through Processing) is internationally recognized by the securities industry, which is to manage securities trades throughout the trade lifecycle automatically and without human intervention. However, while attempting to achieve STP, care must be taken to ensure...

Background and Purpose: The aim of the present study, based at Duke University and involving 14 other institutions, is to identify the most appropriate and cost-effective clinical strategies for prevention of ischemic (thrombotic or embolic) stroke in high-risk individuals and to design and test an intervention to disseminate this information to providers and the public. Methods: The study uses...
