Although numerous antimicrobial agents have been used to treat disseminated Mycobacterium avium complex (MAC) infection, the optimal therapy for this disease is unknown. One potentially effective agent is rifabutin, which has demonstrated activity against MAC both in vitro and in animal models of infection. In clinical trials, cultures of blood from 46% to 92% of patients become sterile after t...

Enhancement the Performance of MANET (Mobile Ad-hoc Network) using spatial d iversity. Spatial d iversity implemented using cooperative transmission technique in Medium access control (MAC) layer level protocol. In noisy environment limit the network performance like coverage area, limit number of node, degrade packet transmission rate, increase packet loss rate etc. In this paper enhance the s...

BACKGROUND Mycobacterium avium-intracellulare (MAC) causes progressive lung disease. Recommended treatment regimens include a macrolide and a rifamycin, but drug intolerance and relapse after treatment is completed often limit successful therapy. METHODS Consecutive individuals referred for treatment of MAC lung disease were treated with a regimen that included either clarithromycin, 500 mg b...

N-screen is a promising technology to improve support for multimedia multicasting, content sharing, content mobility, media scalability, and seamless mobility. In this paper, the WiMedia distributed-MAC (D-MAC) protocol is adopted for development of a seamless N-screen wireless service. Furthermore, to provide a multi-hop, one source multi-use N-screen service through point to point streaming i...

OBJECTIVE Recently, to further enhance the potential in the management of difficult airways, the highly angulated D-Blade was added to the C-MAC system. The purpose of this study was to investigate the laryngoscopic view and intubation parameters using the new C-MAC D-Blade in comparison to the conventional C-MAC video laryngoscope and Macintosh direct laryngoscope in simulated easy and difficu...

Extensive researches on Wireless Sensor Networks (WSNs) have been performed and many techniques have been developed for the data link (MAC) layer. Most of them assume single-channel MAC protocols. In the usual dense deployment of the sensor networks, single-channel MAC protocols may be deficient because of radio collisions and limited bandwidth. Hence, using multiple channels can significantly ...

In this paper, a Dual Channel Allocation (DCA) Scheme for UWB (Ultra Wide Band) with D-MAC (Distributed Medium Access Control) is proposed. Since distributed characteristic of the WiMedia DMAC supporting DRP (Distributed Reservation Protocol) scheme may cause lots of conflicts, overall performances of the WiMedia D-MAC can be deteriorated. Such DRP termination and renegotiation time delays due ...

In this paper, we present a new dual-level matching algorithm for 3-stage Clos-network packet switches, called d-MAC. Using a two-level matching algorithm, namely module-level matching and port-level matching, d-MAC is highly scalable and maintains high system performance. The module-level matching is responsible for finding the module-to-module matching according to the queue status of the swi...
