A minimal model for excitable and bursting elements

Neurocomputing, 2001
Abstract We propose a simple map (a dynamical system with discrete time) as a minimal formal model of excitable and bursting cells. The map has two fast variables and a single slow one and presents all the usual behavior of excitable cells like fast spiking, regular spiking, bursting, plateau action potentials and adaptation phenomena. The simplicity

Minimal Elements of the Poset of a Hammock

Journal of the London Mathematical Society, 1992
Let \(A\) be a (basic and connected) finite dimensional \(k\)-algebra, where \(k\) is an algebraically closed field. Therefore, \(A\) is isomorphic to \(k\Delta /I\), where \(k\Delta\) is the path algebra of a quiver \(\Delta = (\Delta_ 0,\Delta_ 1)\), and \(I\) is an admissible ideal.

Minimal elements for product orders

Optimization, 2008
The aim of the present article is to generalize several results of 19 for product spaces X × V, where X is a complete metric space and V is a Banach space and to give considerably simplified proofs. Moreover, we discuss sufficient conditions for the decisive assumptions as well as an application to vector optimization problems.

A Characterization of Properly Minimal Elements of a Set

SIAM Journal on Control and Optimization, 1985
The notion of properly minimal elements plays an important role in vector optimization. This paper characterizes the properly minimal elements of an arbitrary set in a real normal space with a partial ordering (induced by a convex cone) by the minimal solution of an appropriate approximation problem without any convexity assumption.

On the second role of the random element in minimization

Contemporary Clinical Trials, 2010
Although the main reason for adding a random element at every step of minimization procedure is to reduce predictability of the upcoming treatment assignments in single-center open-label trials, there is another reason for its use, applicable to double-blind trials.

Minimal partial hyperclones on a two-element set

Proceedings. 34th International Symposium on Multiple-Valued Logic, 2004
Let A be a two-element set. It has been proven by Machida that the lattice of hyperclones has continuum cardinality. The current paper first determines all the minimal partial hyperclones. Following this, the authors give all three-element subsets of minimal hyperoperations whose union generates the clone of all hyperoperations as well as all four ...

Shrinkability of Minimal Elements in Sphere Representations of Posets

Order, 1997
As main results the authors prove the following theorems: 1. For every \(k\geq 2\) there exists a poset \(P= (X,\leq)\) so that \(P\) is a \(k\)-sphere order, but there is no \(k\)-sphere representation which assigns to every minimal element a ball of radius zero. 2. There exists a planar graph \(G\) so that no circle representation of \(P(G)\) has all

Minimal Designs of Reversible Sequential Elements

2014
In this paper we propose minimal designs of reversible sequential elements. The proposed designs have been synthesized using exact multiple control Toffoli network synthesis algorithm with SAT/SMT techniques. The designs have minimal gate count, minimal garbage bits, optimal quantum cost and optimal delay. The optimized sequential circuits are compared
