BACKGROUND Finding eligible studies for meta-analysis and systematic reviews relies on keyword-based searching as the gold standard, despite its inefficiency. Searching based on direct citations is not sufficiently comprehensive. We propose a novel strategy that ranks articles on their degree of co-citation with one or more "known" articles before reviewing their eligibility. METHOD In two in...

ischaemic death is considered, it is the association of thrombosis with atherosclerosis that is paramount. It is important to understand the concepts of ‘plaque’ burden; the average number of plaques in the coronary arteries and the nature of plaques appear to determine the incidence of CHD. The level of inflammatory activity in the plaque makes it vulnerable and may lead to precipitation of th...

Amniotic fluid embolism was first recognized in 1926, in a Brazilian journal case report, on the basis of large amounts of fetal material in the maternal pulmonary vasculature at autopsy. The first English language description appeared in 1941 and consisted of eight parturients dying suddenly in which, once again, fetal material was seen in the pulmonary vasculature. A control group of 34 pregn...

Recently metamaterials have inspired worldwide researches due to their exotic properties in transmitting, reflecting, absorbing or refracting specific electromagnetic waves. Most metamaterials are known to have anisotropic properties, but existing anisotropy models are applicable only to a single meta-atom and its properties. Here we propose an anisotropy model for asymmetrical meta-atom cluste...

the present study examined the effect of grouped meta-cognitive therapy on meta-cognitive beliefs of patients' anxieties suffering from generalized anxiety disorder. this research is a quasi-experimental with pre-test and post-test design with control group in which two groups of experiment and control are used. the present study population includes all state universities, islamic azad uni...

conclusions the results of this research have important implications regarding the attention of students’ counselors to meta-cognitive dimensions in order to prevent students’ tendency for addiction. results the rate of students’ addiction potential tendency can be predicted by having characteristics of their meta-cognition. it also appeared that among the five parameters of meta-cognition, the...

We present a logical programming language, generative clause programs, which generalize definite clause programs with a meta-programming level. The fundamental notion in the language is that of a meta-goal which consists of a plain goal together with a program in which it is expected to be true. The declarative semantics can be defined in terms of Herbrand models consisting of such meta-goals. ...

We have prepared the first examples of B9-connected trivalent aryl and alkyl phosphinoborane species via Pd-catalyzed phosphination of 9-iodo-meta-carborane. Our studies highlight the unique electronic features of the B9-connected meta-carboranyl moiety as compared to its C1-based analogue. This work suggests that the B9-functionalized meta-carboranyl substituent in these ligands exhibits more ...

Fluent Logic Programming (FLP) is an attempt to suitably combine into a simple language ideas coming from well known temporal reasoning frameworks like Kowalski's Event Calculus and Sandewall's Features and Fluents. In this paper we propose the core syntax of FLP together with two complementary semantics. The rst one is a x-point semantics which declaratively captures the operational notion of ...
