Kinder and Shanks report simulations aimed at describing a single-system model of the dissociation between declarative and non-declarative memory. This model attempts to capture both Artificial Grammar Learning (AGL) and recognition memory with a single underlying representation. However, the model fails to reflect an essential feature of recognition memory - that it occurs after a single expos...

In this essay I examine the ways in which the Belousov– Zhabotinsky (BZ) reaction is being used by biologists to model a variety of biological systems and processes. The BZ reaction is characterized as a functional model of biological phenomena. It is able to play this role because, though based on very different substrates, the model and system modeled are examples of the same type of excitabl...

TH E R E are four factors which are generally accepted as governing the purchase of lamb and mutton. The first and perhaps the most important is " f o rm. " The best formed lambs have good width in proportion to length with smooth, compact, even outlines. This insures a thick loin, with well meated ribs, a ful l thick middle from shoulder to leg, with evenly covered shoulders. The legs are full...

This paper discusses chatter vibration in turning of a low-rigidity workpiece with parallel leaf spring structure shanks. Because the is suppressed by control tool direction, shank that reduces stiffness artificially height direction studied to design 1st report. In this report, directions and dynamic component cutting force were characterized vibration. The compliances measured identify princi...

Newell & Shanks (N&S) argue that an explanation for blindsight need not appeal to unconscious brain processes, citing research indicating that the condition merely reflects degraded visual experience. We reply that other evidence suggests blindsighters' predictive behavior under forced choice reflects cognitive access to low-level visual information that does not correlate with visual conscious...

This is the second of a pair of papers which describe an investigation into the feasibility of providing artificial balance to paraplegics using electrical stimulation of the paralyzed muscles. By bracing the body above the shanks, only stimulation of the plantar flexors is necessary. This arrangement prevents any influence from the intact neuromuscular system above the spinal cord lesion. In t...

Situations that present individuals with a conflict between local and global gains often result in a behavioral pattern known as melioration — a preference for immediate rewards over higher long-term gains. Using a variant of a paradigm by Tunney & Shanks (2002), we explored the potential role of feedback as a means to reduce this bias. We hypothesized that frequent and informative feedback abo...

Let L be a time-periodic Tonelli Lagrangian on a closed manifold of dimension two. Then the β-function of L is differentiable in at least k directions at any k-irrational homology class. The same result holds when L is an autonomous mechanical Lagrangian with a C potential on a closed manifold of dimension three.

The Tonelli existence theorem in the calculus of variations and its subsequent modifications were established for integrands f which satisfy convexity and growth conditions. In our previous work a generic well-posedness result (with respect to variations of the integrand of the integral functional) without the convexity condition was established for a class of optimal control problems satisfyin...
