Obesity is a serious disorder and an increasing problem all over the world. During the past several decades, the worldwide prevalence of obesity has steadily risen, with the greatest increase occurring in the United States. The incidence of obesity has doubled in adults and tripled in children in the United States over the past 30 years; more than 60 million adults and 9 million children aged 6...

In this paper we study the class of square matrices A such that AA − AA is nonsingular, where A stands for the Moore–Penrose inverse of A. Among several characterizations we prove that for a matrix A of order n, the difference AA−AA is nonsingular if and only if R(A) ⊕ R(A) = Cn,1, where R(·) denotes the range space. Also we study matrices A such that R(A) = R(A).

We consider constraint satisfaction problems parameterized above or below guaranteed values. One example is MaxSat parameterized above m/2: given a CNF formula F with m clauses, decide whether there is a truth assignment that satisfies at least m/2 + k clauses, where k is the parameter. Among other problems we deal with are MaxLin2-AA (given a system of linear equations over F2 in which each eq...

The scalability of cache coherency schemes plays a major role in the overall performance of any scalable distributed system that utilises client data caching. In particular, transactional cache coherency algorithms must be scalable if the systems that are built around them, such as persistent object stores, are to be scalable. The avoidance-based transactional cache coherency [Hughes 1998] algo...
