ventilation tube (vt) insertion is the most common otologic operations performed in children, which has great importance in recovery and prevention of hearing loss in children with eustachian tube dysfunction in critical ages of growth development. the location of the vt insertion varies in different studies; the differences are in recovery rates and sequelae of vt insertion. this study is perf...

introduction one of the most important pre-processing steps in optical coherence tomography (oct) is reducing speckle noise, resulting from multiple scattering of tissues, which degrades the quality of oct images. materials and methods the present study focused on speckle noise reduction and edge detection techniques. statistical filters with different masks and noise variances were applied on ...

The data replication problem (DRP) describes the task of distributing copies of data records (that is, database fragments) among a set of servers in a distributed database system. For the application of flexible query answering, several fragments can be overlapping (in terms of tuples in a database table). In this paper, we provide a formulation of the DRP for horizontal fragmentations with ove...

background: spinal cord injury (sci) is a major clinical condition and research is commonly done to find suitable treatment options. however, there are some degrees of spontaneous recovery after sci and gender is said to be a contributing factor in recovery, but this is controversial. this study was done to compare the effects of sexual dimorphism on spontaneous recovery after spinal cord injur...
