Blood pressure and renal sodium handling in relation to genetic variation in the DRD1 promoter and GRK4.

Activation of type-1 dopamine receptors (DRD1) reduces renal sodium reabsorption. In a family-based random sample of 611 untreated whites (women, 45.0%; mean age, 38.

Adaptive estimation of single response evoked potentials.

A new adaptive filtering algorithm and structure is developed to estimate response-to-response variations in evoked responses. The evoked responses are modeled as the sum of three uncorrelated signal components: ensemble average, noise, and stochastic signal variation. A two stage time sequenced filter structure exhibiting improved convergence characteristics is developed along with a modified P-vector algorithm (mPa) which eliminates the need for a separate desired signal electrode.

Optical processing based on conditional higher-order trinary modified signed-digit symbolic substitution.

Techniques for higher-order modified signed-digit trinary arithmetic by using optical symbolic substitution are presented. This method provides fast multibit computation by adopting a two-step symbolicsubstitution scheme. Since more information is represented in fewer digits, this technique leads to a compact design.
