While in string theory the subject of sources in imaginary time has received some attention, we demonstrate the power of imaginary sources by proving that they constitute in several field theories a complete basis for all smooth and time dependent source free solutions. These proofs promote the study of imaginary sources to a new and crucial viewpoint for understanding time dependent background...

In this study, we examined the construct of the imaginary audience (Elkind & Bowen, 1979), presumably a precipitant of adolescent egocentrism, as it relates to public individuation and self-consciousness. We hypothesized that the imaginary audience inhibits public individuation and represents a critical form of public self-consciousness. We also argued that the imaginary audience is a normal as...

This expository paper is based on the theory of imaginary geometry, due to Sheffield and Miller. We aim to explain enough of the theory for the reader to understand the main constructions and some basic interactions between them in a short time. We suppress the more technical aspects when possible to focus attention on building geometric intuition.

Unlike the Metelli monochrome transparencies, when overlays and their backgrounds have chromatic content, the inferred surface colors may not always be physically realizable. In these cases, the inferred chromatic transmittance or reflectance of the overlay is imaginary, lying outside the RGB spectral boundaries. Using the classical Metelli configuration, we demonstrate this illusion, and brief...

We present a general approach to describe slowly driven quantum systems both in real and imaginary time. We highlight many similarities, qualitative and quantitative, between real and imaginary time evolution. We discuss how the metric tensor and the Berry curvature can be extracted from both real and imaginary time simulations as a response of physical observables. For quenches ending at or ne...

background: as part of the process of developing a decision aid for carpal tunnel syndrome (cts) according to the ottawa decision support framework, we were interested in the level of ‘decisional conflict’ of hand surgeons and patients with cts. this study addresses the null hypothesis that there is no difference between surgeon and patient decisional conflict with respect to test and treatment...
