results inter-observer agreement of the pathology scores based on nas scoring system was acceptable for steatosis, lobular inflammation, and fibrosis, but not for hepatocyte ballooning. the intra-observer agreement was acceptable in all scales, with lowest intra-class correlation observed for lobular inflammation. materials and methods the anonymous liver biopsy samples of 100 consecutive nafld...

background: this study was aimed to compare the diagnostic accuracy and feasibility of cone beam computed tomography (cbct) with phosphor storage plate (psp) in detection of simulated occlusal secondary caries. materials and methods: in this in vitro descriptive-comparative study, a total of 80 slots of class i cavities were prepared on 80 extracted human premolars. then, 40 teeth were randomly...

This paper describes a distributed infrastructure for querying network graphs with recursive queries. We argue that recursive queries have great practical value as a declarative interface to multi-hop networks. To query these networks in a distributed fashion, we describe the processing of recursive queries using PIER, a P2P relational query processor that utilizes distributed hash tables (DHTs...

In recent years, there have been strong interests in the networking community in designing new Internet architectures. One of the driving forces behind these “clean-slate” designs is the need to address pressing security concerns of the Internet. As a consequence, recent architectures, such as SCION [8] and ICING [5], provide radically new architectures that claim to provide stronger security g...

this paper addresses the design of an observer-based fault diagnosis scheme, which is applied to some of the sensors and actuators of a wind turbine benchmark model. the methodology is based on a modified sliding mode observer (smo) that allows accurate reconstruction of multiple sensor or actuator faults occurring simultaneously. the faults are reconstructed using the equivalent output error i...

this paper addresses a nonlinear observer based control scheme to synchronize chaotic systems subject to uncertainties and external disturbances. it is assumed that the dynamic of slave system is not completely known. in order to compensate for the system perturbation resulting from parameter variations and mismodeling phenomena, an adaptive neural network observer is employed to handle this pr...

Declarative networking is a programming methodology that enables developers to concisely specify network protocols and services, and directly compile these specifications into a dataflow framework for execution. This paper describes recent advances in declarative networking, tracing its evolution from a rapid prototyping framework towards a platform that serves as an important bridge connecting...

Experiments were conducted to investigate the effects of farming sites, seeding date, age of oysters, ploidy level and rearing structures on mor tality, pathogens and energetic reserves of oysters Crassostrea gigas. Mortality of oysters coincided with infections involving, primarily, the ostreid herpesvirus OsHV-1 and, secondarily, bacteria of the group Vibrio splendidus, when seawater temperat...
