We study the question of whether the class DisjNP of disjoint pairs (A,B) of NPsets contains a complete pair. The question relates to the question of whether optimal proof systems exist, and we relate it to the previously studied question of whether there exists a disjoint pair of NP-sets that is NP-hard. We show under reasonable hypotheses that nonsymmetric disjoint NP-pairs exist, which provi...
P versus NP is considered as one of the most important open problems in computer science. This consists knowing answer following question: Is equal to NP? It was essentially mentioned 1955 from a letter written by John Nash United States National Security Agency. However, precise statement problem introduced independently Stephen Cook and Leonid Levin. Since that date, all efforts find proof fo...
Background and Aims: The novel approaches in influenza vaccination have targeted more conserved viral proteins such as nucleoprotein (NP) to provide cross protection against all serotypes of influenza A viruses. Influenza specific cytotoxic T lymphocytes (CTL) are able to lyse influenza-infected cells by recognition of NP, the major target molecule in virus for CTL responses. On the other hand,...
In English the NP1 V NP2 construction typically involves arguments that are construed as Agent and Patient, or Subject Object. It is associated with notion of transitivity analyzed accordingly, even when it exhibits only syntactic properties but not its semantic characteristics. This phenomenon well-known has been accounted for by linguists (Lakoff 1977; Hopper Thompson 1980, among others) a re...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
objective(s): nanotechnology and nanoparticles are increasingly recognized for their potential applications in aerospace engineering, nanoelectronics, and environmental remediation, medicine and consumer products. more importantly is the potential for the application of silver nanoparticles (ag nps) in the treatment of diseases that require maintenance of circulating drug concentration or targe...
An impairment of energy metabolism may underlie slow excitotoxic neuronal death in neurodegenerative diseases. We therefore examined the effects of intrastriatal, subacute systemic, or chronic systemic administration of the mitochondrial toxin 3-nitropropionic acid (3-NP) in rats. Following intrastriatal injection 3-NP produced dose-dependent striatal lesions. Neurochemical and histologic evalu...
