BACKGROUND The diagnosis of pleural tuberculosis (TB) remains to be difficult. Interferon-gamma release assay (IGRA) is a promising method for diagnosing TB in low TB burden countries. The release of interferon-gamma (IFN-γ) by T lymphocytes increases at a localized site of infection with Mycobacterium tuberculosis antigen. This study aimed to examine the(More)
This paper presents a manageable overlay network architecture <i>SVCP2P</i> for live scalable media streaming. Every peer in <i>SVCP2P</i> periodically exchanges data availability information with one of distributed central servers which act as the centralized index for storing peer list, program list and buffer information of peers. An efficient scheduling(More)
It is known that differential microphone arrays are sensitive to microphone mismatches. This paper studies the effects of microphone mismatches on the directivity factor (DF) of the first-order steerable differential array (FOSDA) whose response is constructed by a linear combination of monopole and two orthogonal dipoles via a small four-microphone array.(More)
