Cowpea chlorotic mottle virus (CCMV) replicated in tobacco suspension cell protoplasts inoculated with in vitro transcripts of CCMV RNA1, 2, and 3. CCMV RNA-dependent RNA polymerase (RdRp) isolated from these protoplasts specifically recognized CCMV and Brome mosaic virus (BMV) subgenomic RNA promoters and directed in vitro RNA synthesis in a manner indistinguishable from CCMV RdRp more laborio...

In this paper, we investigate a constrained portfolio selection problem with cardinality constraint, minimum size and position constraints, and non-convex transaction cost. A hybrid method named Local Search Branch-and-Bound (LS-B&B) which integrates local search with B&B is proposed based on the property of the problem, i.e. cardinality constraint. To eliminate the computational burden which i...

BACKGROUND Congenital CMV (cCMV) infection is a serious public health issue due to both its worldwide prevalence and the severe and permanent impairments it causes. However, awareness of this infection is low in the general population and among pregnant women, and it also seems to be generally disregarded by healthcare providers. The identification of factors behind this inadequate level of kno...

This paper is concerned with the problem of state estimation for discrete-time linear systems in presence additional (equality or inequality) constraints on (or estimate). By use minimum variance duality, converted into an optimal control problem. Two algorithmic solutions are described: full information estimator (FIE) and moving horizon (MHE). The main result to show that proposed stable sens...
