From Jack to Double Jack Polynomials via the Supersymmetric Bridge

The Calogero–Sutherland model occurs in a large number of physical contexts, either directly or via its eigenfunctions, the Jack polynomials. The supersymmetric counterpart of this model, although much less ubiquitous, has an equally rich structure. In particular, its eigenfunctions, the Jack superpolynomials, appear to share the very same remarkable combinatorial and structural properties as t...

Ligature of Carotid Artery

Sik,?I shall feel obliged if you kindly publish this case in your esteemed Gazette. Ananta, a Hindu male, an inhabitant of Patna, aged 35, was admitted in the Mayo Hospital on the 16tli April 1910, for a swelling of ten months' duration in the upper part of the left side of the neck with a sinus. This swelling was supposed to be due to suppurating gland. He was put under chloroform for the oper...

Embodying the JACK Agent Architecture

Agent-based models of human operators rarely include explicit representations of the timing and accuracy of perception and action, although their accuracy is sometimes implicitly modelled by including random noise for observations and actions. In many situations though, the timing and accuracy of the person’s perception and action significantly influence their overall performance on a task. Rec...
