Ecologists are fascinated by the prevalence of nestedness in biogeographic and community data, where it is thought to promote biodiversity in mutualistic systems. Traditionally, nestedness has been treated in a binary sense: species and their interactions are either present or absent, neglecting information on abundances and interaction frequencies. Extending nestedness to quantitative data fac...

Transactional Memory (TM) simplifies parallel programming by transferring responsibility for concurrency management from the programmer to the system. Nevertheless, a number of challenges must be addressed for TM to be widely adopted. This dissertation presents work towards improving the practicality of TM across three dimensions. The first challenge addressed is that of integrating TM with pop...

We have established the Nested Relational Sequence Model (NRSM), which is an extension of the Nested Relational Data Model in order to handle XML data. The NRSM incorporates the value order, the sibling order and the ancestor order. In this paper, we demonstrate NRS operations by examples and illustrate how XML queries can be formulated. We discuss the work related to implementing the NRSD Syst...

Named entity recognition plays an important role in many natural language processing applications. While considerable attention has been pain in the past to research issues related to named entity recognition, few studies have been reported on the recognition of nested named entities. This paper presents a morpheme-based due-layer labeling method to Chinese nested named entity recognition. To a...

An overhead contact system (OCS) is key to providing power high-speed railways. OCS detection an important measure ensure the safe operation of a railway. At present, anomaly mainly relies on manual analysis images regularly collected by 4C system, which very inefficient and can easily miss anomalies. Although some classification object methods based deep learning be used for detection, effecti...

In 1997, E787 at BNL reported evidence for the rare decay K+ ! +  based on the observation of one event in the 1995 data set. The current status of this measurement is described. Supported by the Natural Sciences and Engineering Research Council of Canada c 1998 by George Redlinger.

Modern electric power systems have witnessed rapidly increasing penetration of renewable energy, storage, electrical vehicles, and various demand response resources. The infrastructure planning is thus facing more challenges as a result the variability uncertainties arising from diverse new This study aims to develop multistage multiscale stochastic mixed integer programming (MM-SMIP) model cap...

conclusions the study indicated that the rate of p. jirovecii infection is similar to those reported from asian, indian and african countries. the similarity of the genetic pattern between iranian and indian isolates is probably due to their close geographical proximity. patients and methods we used two nested pcr and pcr-rflp assays to amplify mt lsu rrna and dhps genes in 126 samples obtained...
