We propose a non-perturbative method for computing the renormalization constants of generic composite operators. This method is intended to reduce some systematic errors, which are present when one tries to obtain physical predictions from the matrix elements of lattice operators. We also present the results of a calculation of the renormalization constants of several two-fermion operators, obt...

This was a multicenter, randomized, placebo-controlled clinical trial of a stepped anti_hypertensive regimen in selected screenees age 60 years and older, drawn from a community-based ambulatory population in 16 tertiary medical centers in the U.S. From the pool of 447,921 potential candidates, 4,736 were selected as suitable candidates on the basis of informed consent and confirmed systolic bl...

We discuss systematically the consistency of light gluinos with data on perturbative QCD from deep inelastic scattering, quarkonia, jets at LEP, and the total hadronic cross-section in ee annihilation on the Z peak and elsewhere. We demonstrate that, in addition to the well-known increase in the value of αs(mZ) inferred from lower-energy data due to the slower running of αs in the presence of l...

The results of an exploratory lattice study of heavy baryon spectroscopy are presented. We have computed the full spectrum of the eight baryons containing a single heavy quark, on a 24 3 × 48 lattice at β = 6.2, using an O(a)-improved fermion action. We discuss the lattice baryon operators and give a method for isolating the contributions of the spin doublets (Σ, Σ *), (Ξ ′ , Ξ *) and (Ω, Ω *) ...

We provide the solutions of the fixed point conditions of the Yukawa sector for a large class of N = 1 supersymmetric theories including the minimal and next-to-minimal supersymmetric standard models and their grand unified and other extensions. We also introduce a test which can discriminate between infra-red stable, infra-red unstable and saddle point solutions, and illustrate our methods wit...

The pilot study of the Systolic Hypertension in the Elderly Program was a randomized, double-blind, placebo-controlled trial of drug therapy for isolated systolic hypertension. It followed 551 elderly participants with untreated blood pressures of greater than 160/less than 90 mm Hg for an average of 34 months. Mean age of the participants was 72 years; 63% were women, and 82% were white. Pretr...

In preparation for blood pressure determination, the midarm circumference was measured on the bared right upper arm, with the participant standing. The appropriate size cuff was then selected from a chart of arm circumference measurements and corresponding cuff sizes (Table 5.1) (SHEP Blood Pressure Manual). Measurements of blood pressure and pulse rate were performed only after the participant...
