Data on nontuberculous mycobacterial (NTM) disease in sub-Saharan Africa are limited. During 2006-2008, we identified 3 HIV-infected patients in northern Tanzania who had invasive NTM; 2 were infected with "Mycobacterium sherrisii" and 1 with M. avium complex sequevar MAC-D. Invasive NTM disease is present in HIV-infected patients in sub-Saharan Africa.

Stable cohomotopy groups of Eilenberg-Mac Lane spectra of finite groups are shown to be trivial. This implies that the stable homotopy category, which is large enough to represent ordinary cohomology theory, cannot be self-dual. It can also be interpreted as an evidence to support Freyd's generating hypothesis and a proof of a stable version of a conjecture of D. Sullivan.

We have identified a family of abundant peripheral plasma membrane glycoproteins that is unique to flowering plants. They are identified by a monoclonal antibody, MAC 207, that recognizes an epitope containing L-arabinose and D-glucuronic acid. Immunofluorescence and immunogold labeling studies locate the MAC 207 epitope to the outer surface of the plasma membrane both in protoplasts and in int...

This paper deals with a novel MAC layer protocol, namely, directive synchronous transmission asynchronous reception (D-STAR) able to space-time synchronize a wireless sensor network (WSN). To this end, D-STAR integrates directional antennas within the communications framework, while taking into account both sleep/active states, according to a cross-layer design. After characterizing the D-STAR ...

In this paper, an analytic model is built to study the medium access control (MAC) performance and reliability of general two-dimensional (2-D) IEEE 802.11 based wireless networks for one-hop broadcast communications. First, a semi-Markov process (SMP) model is introduced to capture the medium contention and backoff behavior and the impact of hidden terminal problem in IEEE 802.11 broadcast wir...

Background Video laryngoscope-aided intubations require less force to align oral, pharyngeal, and laryngeal planes to visualize the glottis opening during intubation. Aim The primary objective of the study was to assess the incidence and severity of postoperative sore throat (POST) in patients who were intubated with C-MAC video laryngoscope using D-blade versus traditional Macintosh laryngos...

network In this article, the author proposes a novel MAC-layer protocol, called Optical Reservation Multi stations to reserve transmission slots, which is attractive for use in fiber optic networks. Unlike conventional protocols, w is mostly done using software, ORMA performs its reservation using simple and effective optical circuits.
