Logrank Tests (Freedman)

This module allows the sample size and power of the logrank test to be analyzed under the assumption of proportional hazards. Time periods are not stated. Rather, it is assumed that enough time elapses to allow for a reasonable proportion of responses to occur. If you want to study the impact of accrual and follow-up time, you should use the one of the other logrank modules also contained in PA...

Euclidean Freedman–Schwarz model

The N=4 gauged SU(2)×SU(1,1) supergravity in four-dimensional Euclidean space is obtained via a consistent dimensional reduction of the N=1, D=10 supergravity on S × AdS3. The dilaton potential in the theory is proportional to the difference of the two gauge coupling constants, which is due to the opposite signs of the curvatures of S and AdS3. As a result, the potential can be positive, negati...

system, where non-sexualised images, e.g. from clothes ads or even from nudist beaches get the green light, erotic posing counts as amber, and material focusing on genitals or actual acts of child abuse gets the red light. “We train the patient to move only in the green area,” Ahlers told the paper. “Amber means: Caution! Potential danger for children and for myself! Risky behaviour on the verg...
