Expeditious growth of Internet and related network technologies has spectacularly increased the popularity of social networking systems such as blogs, forums, reviews sites etc. These systems allow the web users to share and disseminate their experiences and opinions with millions of users across the globe. This collaborative behavior of community can be observed as an electronic word of mouth ...

Recommender systems are a valuable means for online users to find items of interest in situations when there exists a large set of alternatives. Collaborative Filtering (CF) is a popular technique to build such systems which is based on explicit rating feedback on the items by a larger user community. Recent research has demonstrated that the predictive accuracy of CF based recommender systems ...

Recommendation systems have become an important tool to overcome information overload and help people to make the right choice of needed items, which can be e.g. documents, products, tags or even other people. Last attribute has aroused our interest: Scientists are in need of different collaboration partners, i.e. experts for a special topic similar to their research field, to work with. Co-cit...

The single-span membrane protein KCNE3 modulates a variety of voltage-gated ion channels in diverse biological contexts. In epithelial cells, KCNE3 regulates the function of the KCNQ1 potassium ion (K(+)) channel to enable K(+) recycling coupled to transepithelial chloride ion (Cl(-)) secretion, a physiologically critical cellular transport process in various organs and whose malfunction causes...

RATIONALE Cystic fibrosis (CF) is a recessive genetic disease characterized by dehydration of the airway surface liquid and impaired mucociliary clearance. As a result, individuals with the disease have difficulty clearing pathogens from the lung and experience chronic pulmonary infections and inflammation. There may be intermittent pulmonary exacerbations or acute worsening of infection and ob...

This is a continuation of my earlier work [9], where we study the lower bound of the Mabuchi energy on Kähler manifolds when the first Chern class is negative. The problem of finding a lower bound for the Mabuchi energy is very important in Kähler geometry since the existence of a lower bound is the pre-condition for the existence of constant scalar curvature metric in a Kähler class (cf. [2] a...

The study of norms (Ns) is recent but growing concern in the AI field (cf. [MOS92]; [SHO92]) as well within other formal approaches to social action, such as Game Theory (where theories of Ns began to appear long before, cf.[LEW69]; [ULL77]). The normative is an essential dimension of social life. An explicit model of such dimension is crucial for any theory of social action. Notions such as "s...

We present a non-commutative linear logic | the logic of predicates with equality and explicit substitutions. Thus, the position of linear logic with respect to the usual logic is given a new explanation. 1 The world according to Girard A recent introduction to linear logic, cf. 13], starts with the following explanation of the position of usual logic with respect to the linear. Linear logic is...

Based on the controversial beliefs among L2 teachers about effective corrective feedback (CF) strategies, recast and prompts as 2 kinds of CF have drawn the attention of L2 researchers(e.g., Braidi, 2002; Iwashita, 2003; Loewen & Philp, 2006; Panova & Lyster, 2002; Sheen, 2004). Despite these numbers of studies, debate continues to exist about their usefulness as a CF technique. Whereas recasts...

Special Lagrangian submanifolds may be defined as those submanifolds which are both Lagrangian (an order 1 condition) and minimal (an order 2 condition). Alternatively, they are characterised as those submanifolds which are calibrated by a certain n-form (cf [HL]), so they have the remarkable property of being area minimizing. Their study have received many attention recently since connections ...
