The IBM POWER A processor is the dominant reduced instruction set computing microprocessor in the world today, with a rich history of implementation and innovation over the last 20 years. In this paper, we describe the key features of the POWER7 A processor chip. On the chip is an eight-core processor, with each core capable of four-way simultaneous(More)
Tuberculosis is the most common opportunistic infection in patients with HIV infection worldwide and is the only one that is transmissible to others by the respiratory route. Tuberculosis is curable and preventable. Early detection of tuberculosis disease and infection in individuals with or at risk for HIV infection is paramount. This approach can minimize(More)
The impact of the acquired immunodeficiency syndrome (AIDS) pandemic has made tuberculosis an increasing worldwide problem, and the effectiveness of modern chemotherapy has been blunted by the high incidence of primary drug resistance, especially in developing countries. The prospect of finding new and highly effective drugs similar to isoniazid or(More)
SETTING Los Angeles County Department of Health Services. OBJECTIVE To determine how well a self-administered fixed dose combination of isoniazid and rifampin (CombinedHR) prevents acquired drug resistance to Mycobacterium tuberculosis despite treatment interruptions. DESIGN Self-administered CombinedHR was given to approximately 75% of patients and(More)
In this paper, bidirectional pair-wise communication between 2K nodes is considered. Each node has N antennas and wants to transmit d data streams to its communication partner. A single non-regenerative half-duplex relay with R antennas supports the communication. In this scenario, the process of interference alignment can be decomposed into partial signal(More)
—A wireless Ad Hoc network consisting of a source and multiple receiving nodes is considered. The source wants to transmit a common message throughout the whole network. The message has to be spread in a multi-hop fashion, as the transmit powers at the source and the nodes are limited. The goal of this paper is to find the multi-hop broadcast tree with a(More)
