Massive Australian Precambrian/Cambrian Impact Structure Massive Australian Precambrian/Cambrian Impact Structure The Massive Australian Precambrian/Cambrian Impact Structure also known as MAPCIS is a proposed impact structure based upon arguments presented by Daniel P. Connelly at Geological Society of America meetings. Its center is located approximately equidistant between Uluru (Ayers Rock) and Mount Conner in Australia's Northern Territory. The structure is approximately in diameter. However, a hypothetical outermost ring in diameter is claimed to be the result of undefined far field stresses. Connelly argues that the age of this hypothetical impact is approximately 545 mya which puts it just before the Cambrian explosion (542 mya) of the
Attraction to transgender people to 92% identified their sexual identity as straight or bisexual. A study employing the penile plethysmograph demonstrated that the arousal patterns, genital and subjective, of men who self-report attraction to trans women are similar to those of straight men, and different from those of gay men. The study showed that those men, also known in literature as "gynandromorphophiliacs", are much more strongly aroused to female than to male stimuli. They differ from both straight and gay men, however, in displaying strong arousal to stimuli featuring trans women, which in this group was as arousing as the female stimuli. The study
