is fully appreciated that research may $ take diverse forms, works of a simply p speculative or impressionistic character ^ are therefore excluded. Of coursen valuable contributions are often made, f?r t instance, by trained workers writing in* \ formally about their experiences. The intention is not to disregard material of , this kind. Nevertheless, it remains true ; that the survey is concer...

We study substitute vectors to solve the part-of-speech ambiguity problem in an unsupervised setting. Part-of-speech tagging is a crucial preliminary process in many natural language processing applications. Because many words in natural languages have more than one part-of-speech tag, resolving part-of-speech ambiguity is an important task. We claim that partof-speech ambiguity can be solved u...

blood transfusion centers are under considerable pressure to produce platelet concentrates with a shelf life limit of 3 to 5 days. many approaches have been investigated experimentally to produce new hemostatically active platelet products that are capable of long term storage. in this article infusible platelet membrane will be explained as a platelet substitute versus conventional liquid-stor...

surgery on the skeleton frequently requires harvesting of autogenous bone graft from the pelvis, but this procedure often is complicated by problems. the purpose of this retrospective, comparative descriptive study was to compare the efficacy of metal-derived bioactive glass (novabone) versus autogenous iliac crest bone graft in adolescent idiopathic scoliosis surgery. the study was carried out...

A service T can substitute a service S if T interacts with every partner of S in a deadlock-free manner. We introduce the notion of a filtered service of a service S with less or the same traces of external messaging behavior as S, yet can substitute S. We propose a finite representation of all filtered services of S called filtering guidelines. Given a service T that cannot substitute S, we ca...
