Low back pain is one of the most common musculoskeletal symptoms, and it can be difficult to make an accurate diagnosis based on symptoms alone. Osteitis condensans ilii (OCI) benign etiologies low buttock mainly in young multiparous women. It diagnosed by radiological findings triangular sclerotic bone lesion, bilateral iliac sacroiliac joints. Spondyloarthritis a group chronic inflammatory rh...

In this paper, I examine the charge that Gopnik and Meltzoff's 'Child as Scientist' program, outlined and defended in their 1997 book Words, Thoughts and Theories is vitiated by a form of 'cognitive individualism' about science. Although this charge has often been leveled at Gopnik and Meltzoff's work, it has rarely been developed in any detail. I suggest that we should distinguish between two ...

Error-related negativity (ERN/Ne) is a component of the event-related brain potential (ERP) associated with monitoring action and detecting errors. It is a sharp negative deflection that generally occurs from 50 to 150 ms following response execution and has been associated with activity involving the anterior cingulate cortex (ACC). An enhanced ERN has recently been observed in patients with o...

Optimization of an optical coherence imaging (OCI) system on the basis of task performance is a challenging undertaking. We present a mathematical framework based on task performance that uses statistical decision theory for the optimization and assessment of such a system. Specifically, we apply the framework to a relatively simple OCI system combined with a specimen model for a detection task...

conclusions with our laboratory diagnostic method, it seems that there are no cases of oci in patients with aih. however, we recommend further studies with more samples and more precise laboratory method. results six males and 29 females with mean disease duration of 77.1 ± 39.5 month and mean age of 43.62 ± 12.67 years were investigated. all cases were negative for anti-hcv antibody and we cou...

Group communication is a useful mechanism guaranteeing consistency among replicated objects. The existing approaches do not allow transparent plug-in of group communication protocols into CORBA. They either require modification of CORBA or OS, or provide no room for incorporating group communication transport protocols into CORBA. We thus propose a generic group communication framework that all...

The CORBA has many attractive features such as reusability, portability, and interoperability which are key issues in the integration of heterogeneous and distributed computing system. However, it provides little support for fault tolerance and high availability that can be supported by means of object replication. The existing approaches do not support transparent plug-in of group communicatio...
