Evaluating true BCI communication rate through mutual information and language models. [PDF]

open access: yesPLoS ONE, 2013
Brain-computer interface (BCI) systems are a promising means for restoring communication to patients suffering from "locked-in" syndrome. Research to improve system performance primarily focuses on means to overcome the low signal to noise ratio of ...

Poincaré Inequalities for Mutually Singular Measures [PDF]

open access: yesAnalysis and Geometry in Metric Spaces, 2015
Using an inverse system of metric graphs as in [3], we provide a simple example of a metric space X that admits Poincaré inequalities for a continuum of mutually singular measures.

An approximate binary-black-hole metric [PDF]

open access: yes, 2000
An approximate solution to Einstein's equations representing two widely-separated non-rotating black holes in a circular orbit is constructed by matching a post-Newtonian metric to two perturbed Schwarzschild metrics. The spacetime metric is presented in

A Multifaceted Equity Metric System for Transportation Electrification

open access: yesIEEE Open Journal of Intelligent Transportation Systems, 2023
Transportation electrification offers societal benefits like reduced emissions and decreased dependence on fossil fuels. Understanding the deployment of electric vehicles (EVs) and electric vehicle supply equipment (EVSE) has been a popular focus ...

On the measurement problem for a two-level quantum system [PDF]

open access: yes, 2007
A geometric approach to quantum mechanics with unitary evolution and non-unitary collapse processes is developed. In this approach the Schrodinger evolution of a quantum system is a geodesic motion on the space of states of the system furnished with an ...

Fault-tolerance in metric dimension of boron nanotubes lattices

open access: yesFrontiers in Computational Neuroscience, 2023
The concept of resolving set and metric basis has been very successful because of multi-purpose applications both in computer and mathematical sciences.

Measuring thermodynamic length [PDF]

open access: yes, 2007
Thermodynamic length is a metric distance between equilibrium thermodynamic states. Among other interesting properties, this metric asymptotically bounds the dissipation induced by a finite time transformation of a thermodynamic system.

On the topology of the chain recurrent set of a dynamical system

open access: yesApplied General Topology, 2014
n this paper we associate a pseudo-metric to a dynamical system on a compact metric space. We show that this pseudo-metric is identically zero if and only if the system is chain transitive.

On Constant Metric Dimension of Some Generalized Convex Polytopes

open access: yesJournal of Mathematics, 2021
Metric dimension is the extraction of the affine dimension (obtained from Euclidean space Ed) to the arbitrary metric space. A family ℱ=Gn of connected graphs with n≥3 is a family of constant metric dimension if dimG=k (some constant) for all graphs in ...
