Arthur William Prichard

With the death of A. W. Prichard, on January 13th, another old landmark of the medical profession in the West of England passed away. Born at the " Red Lodge," Park Row, Bristol, seventy-three years ago, he took a great deal of interest in this house, and during his life enriched its collection of old Bristol valuables by several gifts. He was the son of Augustin Prichard, a prominent surgeon o...

Commentary / Llewellyn : Elaborative encoding

Although the analogy between dreams and ancient mnemotechniques is tempting because they share several phenomenological characteristics, this analogy is superficial at a closer look. Unlike mneomotechnically encoded material, rapid eye movement (REM) dreams are inherently difficult to remember, do not usually allow conscious subsequent retrieval of all interconnected elements, and have been fou...

The Polymerization of Proteins Adenosine Triphosphate and the Polymerization of Actin by Koloman Laki,* William J. Bowen, and Ariel Clark

Banga and Szent-GySrgyi (1) have found that two kinds of myosin can be obtained from rabbit muscle depending on the time of extraction of the muscle. Muscle extracted for 24 hours yields myosin which is very viscous (myosin B) and the viscosity drops on the addition of adenosine triphosphate (ATP), while muscle extracted for 20 minutes yields myosin which is less viscous and the viscosity does ...

Extreme Bowen-York initial data

The Bowen-York family of spinning black hole initial data depends essentially on one, positive, free parameter. The extreme limit corresponds to making this parameter equal to zero. This choice represents a singular limit for the constraint equations. We prove that in this limit a new solution of the constraint equations is obtained. These initial data have similar properties to the extreme Ker...
