Binding of atrial and brain natriuretic peptides to guanylyl cyclase-A/natriuretic peptide receptor-A produces second messenger cGMP, which plays an important role in maintaining renal and cardiovascular homeostasis. Mice carrying a targeted disruption of the Npr1 gene coding for guanylyl cyclase-A/natriuretic peptide receptor-A exhibit changes that are(More)

The first few widely accepted amendments to IEEE 802.11 wireless networking specifications, namely IEEE 802.11a, IEEE 802.11b, and IEEE 802.11g, featured relatively low spectral efficiencies and data rates. Driven by technological advances in signal processing and communications theory, sustained improvement in spectral efficiency, coverage, and quality of(More)

IEEE 802.11 is a working group operating under the sponsorship of the IEEE Local Area Network (LAN)/Metropolitan Area Network Standards Committee (LMSC). It is responsible for writing standards focusing on wireless LANs (WLANs). A WLAN's typical transmission range is up to 100 m. Unlicensed spectrum is generally considered, including 2.4 GHz, 5 GHz, and 60(More)
This article provides front line social work practitioners with a mechanism for becoming more meaningfully involved in social and public policy analysis. It suggests that a new entry point for shaping policy formulation should occur earlier on in the problem identification stage of the rational policymaking process. The article offers a series of process(More)

In my past two “Standards” columns,
 I provided an extensive
 update on the latest standardization
 developments of Wi-Fi in IEEE 802.11,
 which is a working group operating
 under the sponsor IEEE Local and
 Metropolitan Area Networks (LAN/
 MAN) Standards Committee. In this
 column, I would like(More)
