The last decade has seen the emergence of a variety of cognitive architectures. This is good news, in general, for cognitive modeling, because architectures provide a readymade set of tools and theoretical constraints that can— according to architectural research methodology—assist the cognitive modeling enterprise by constraining the possible models of a set of phenomena or even making the “ri...

In this work, a novel integrable evolution system in the sense of Lax’s scheme associated with mixed spectral Ablowitz-Kaup-Newell-Segur (AKNS) matrix problem is first derived. Then, time dependences scattering data corresponding to AKNS are given inverse analysis. Based on data, reconstruction potentials carried out, and finally analytical solutions four arbitrary functions derived formulated....

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...

Interest to the tasks by bound with systems of the quasilinear equations recently has revived. Therefore we have decided to expose in electronic sort our operation published in Translated from Teoreticheskaya i Matematicheskaya Fizika, Vol. 101, No. 2, pp. 189-199, November, 1994. Original article submitted October 26, 1993. Exact single-wave and two-wave solutions of systems of equations of th...

In the vicinity of the threshold of a continuous pattern-forming instability a description of the basic periodic solution and its slow modulations is possible by perturbation theory [Newell & Whitehead, 1969; Segel, 1969; Stuart & Di Prima, 1978]. For quasi-one-dimensional, stationary, and periodic patterns formed from an unstructured state through a continuous soft-mode finite-q instability, a...

The dynamics of an interface connecting a stationary stripe pattern with a homogeneous state is studied. The conventional approach which describes this interface, Newell–Whitehead–Segel amplitude equation, does not account for the rich dynamics exhibited by these interfaces. By amending this amplitude equation with a nonresonate term, we can describe this interface and its dynamics in a unified...

We introduce and study an integrable boundary flow possessing an infinite number of conserving charges which can be thought of as quantum counterparts of the Ablowitz, Kaup, Newell and Segur Hamiltonians. We propose an exact expression for overlap amplitudes of the boundary state with all primary states in terms of solutions of certain ordinary linear differential equation. The boundary flow is...
