The 24-hour effect of cilazapril monotherapy on blood pressure was evaluated in a controlled, double-blind, randomised, dose-response trial carried out in 6 Scandinavian centres. After 4 weeks of single-blind placebo administration, male and female o

There is no agreed definition for the assessment of vertebral fractures and deformities in patients with osteoporosis. Radiographs of 66 patients randomized for therapy with etidronate or placebo were analyzed at baseline and during follow-up (60/120

A detailed numerical study of a sine-Gordon model of the Josephson tunnel junction is compared with experimental measurements on junctions with different $\frac{L}{{\ensuremath{\lambda}}_{J}}$ ratios. The soliton picture is found to apply well on bot

Half-harmonic generation in Josephson tunnel junctions and microbridges is investigated theoretically, numerically, and experimentally. It is found that such generation may take place both at zero voltage and on rf-induced steps in tunnel junctions,

Measurements of the active properties of a Dayem micro-bridge at X-band frequencies is described. The bridge was mounted in a microwave cavity designed to match the bridge properly and the microwave output from the cavity was detected using a sensiti

The properties of the ac SQUID magnetometer has been analyzed. The results are valid in the low-inductance low-critical-current regime, where the Lri0 producted is belowthe value at which the relation between the enclosed and externally applied magne

The junction capacitance may be determined and the cos amplitude may be estimated from the switching characteristics seen in the IV curve near the critical temperature. The method relies on the empirical observation that a small area tunnel junction

Preliminary measurements on a (quasi-) degenerate parametric amplifier using a single Josephson tunnel junction as the active element is reported. The pump frequency is at 18 GHz and the signal and idler frequencies are both at about 9 GHz. A power g

The zero field steps in the current-voltage characteristic of Josephson tunnel junctions are explained as a manifestation of the oscillatory motion of N solitons in the tunnelling barrier. Here N is the step number. The solitons evolve according to a

Extensive measurements of radiation emitted from long Josephson junctions d.c.-current biased on zero-field and Fiske-steps are reported. The measurements were made in the band 8-10 GHz on long Nb-Nb oxide-Pb overlap tunnel junctions with the lengths
