PURPOSE OF REVIEW Accurate and early identification of high-risk surgical patients allows for targeted use of perioperative monitoring and interventions that may improve their outcomes. This review summarizes current evidence on how information from the preoperative, operative, and immediate postoperative periods can help identify such individuals. RECENT FINDINGS Simple risk indices, such as...

This paper presents a customizable architecture for software agents that capture and access information in large, heterogeneous, distributed electronic repositories. The key idea is to exploit underlying structure at various levels of granularity to build high-level indices with task-speciic interpretations. Information agents construct such indices and are conngured as a network of reusable mo...

Meetings contain a large amount of rich project information that is often not documented. Capturing audio and video of a meeting can provide a comprehensive meeting record. However, finding detailed information in that record can be challenging because there is no structural information other than time to help the user navigate. This paper surveys various ways of creating indices into meeting r...

BACKGROUND Web of Science, Scopus, and Google Scholar are three major sources which provide h-indices for individual researchers. In this study we aimed to compare the h-indices of the academic pediatricians of Mashhad University of Medical Sciences obtained from the above mentioned sources. METHOD Academic pediatrician who had at least 5 ISI indexed articles entered the study. Information re...

to determine the suitable indices for vegetation cover and production assessment based on the remote sensing data, simultaneous digital data with field data belonging to the spring rangeland of the semirom-isfahan province were analyzed. during two years of monitoring the annual, grass, forb, and shrub vegetation cover and the total production data from 86 were collected. the global positioning...

Anatomical distance has been widely used to predict functional connectivity because of the potential relationship between structural connectivity and functional connectivity. The basic implicit assumption of this method is "distance penalization." But studies have shown that one-parameter model (anatomical distance) cannot account for the small-worldness, modularity, and degree distribution of ...

We apply RMT, Network and MF-DFA methods to investigate correlation, network and multifractal properties of 20 global financial indices. We compare results before and during the financial crisis of 2008 respectively. We find that the network method gives more useful information about the formation of clusters as compared to results obtained from eigenvectors corresponding to second largest eige...

OBJECTIVES Acceleration plethysmograms (APGs) are obtained by taking the second derivative of photoplethysmograms (PPGs) and are noninvasive circulatory signals related to risk factors for atherosclerosis with age. There has been growing interest in the development of mobile devices to collect and analyze PPG single features for ambulatory health monitoring. The present study aimed to extract a...
