Response Function Estimates for Sq.

Differences in response to the peptidyldipeptide hydrolase inhibitors SQ 20,881 and SQ 14,225 in normal-renin essential hypertension.

We compared vascular and hormonal responses to teprotide (SQ 20,881) and captopril (SQ 14,225) in patients with normal renin essential hypertension given a 10 mEq sodium diet. In 10 patients receiving SQ 20,881, significant changes occurred in diastolic blood pressure (DBP, -13 +/- 2.5 mm Hg), angiotensin II (-7.1 +/- 2.1 pg/ml), and plasma renin activity (PRA, +6.6 +/- 1.9 ng/ml/hr) (p < 0.01 ...

Nonparametric time-variant frequency response function estimates using arbitrary excitations

The time-variant frequency response function (TV-FRF) uniquely characterizes the dynamic behaviour of a linear timevariant (LTV) system. This paper proposes a method for estimating nonparametrically the dynamic part of the TV-FRF from known input, noisy output observations. The arbitrary time-variation of the TV-FRF is modelled by Legendre polynomials. In opposition to existing solutions, the p...

Some Explicit Estimates for the Möbius Function

L(1, χ) > cε qε and all attempts at providing a value to cε for sufficiently small ε have been unsuccessful. On the other hand, a wide class of functions of prime numbers have been successfully explicitly estimated during the last fifty years, starting with the benchmarking paper of Rosser and Schœnfeld [11]. For instance, refining an earlier estimate of Dusart [4], Trudgian [14] proved that, f...

Remarks on Estimates for the Green Function

Uni6n M a t d t i c a Argentina Vol. 35 1990. Introduction The main purpose of this paper is to give a comprehensive motivation, with most of the key ideas used in the recent work by Garroni and Menaldi [lo], on the construction of the Green function G(z, t, (, r) for an integro-differential initial boundary value problem, when the differential operator is a second-order parabolic operator not ...
