A self-organizing state-space-model approach for parameter estimation in Hodgkin-Huxley-type models of single neurons [PDF]

open access: yes, 2012
Traditional approaches to the problem of parameter estimation in biophysical models of neurons and neural networks usually adopt a global search algorithm (for example, an evolutionary algorithm), often in combination with a local search method (such as ...

A healthcare space planning simulation model for Accident and Emergency (A&E) [PDF]

open access: yes, 2013
The National Health Service (NHS) in the United Kingdom provides a range service for its population including primary care and hospital services. The impact of the 2008 economic and financial crises prompted a tightening of public budgets including ...

Conceptual Space Modeling for Space Event Characterization [PDF]

open access: yes2020 IEEE 23rd International Conference on Information Fusion (FUSION), 2020
This paper provides a method for characterizing space events using the framework of conceptual spaces. We focus specifically on estimating and ranking the likelihood of collisions between space objects. The objective is to design an approach for anticipatory decision support for space operators who can take preventive actions on the basis of ...

A probabilistic model of RNA conformational space. [PDF]

open access: yesPLoS Computational Biology, 2009
The increasing importance of non-coding RNA in biology and medicine has led to a growing interest in the problem of RNA 3-D structure prediction. As is the case for proteins, RNA 3-D structure prediction methods require two key ingredients: an accurate ...

Ideal models of spaces

open access: yesTheoretical Computer Science, 2003
This paper is a continuation of the author's programme of studying when spaces can be `modelled' by representing them as the subspaces of maximal points of continuous posets equipped with the Scott topology. In the present paper he considers `ideal dcpo's' in which every element is either compact or maximal.

Elliptic Model for Space-Time Correlations in Turbulent Shear Flows [PDF]

open access: yes, 2006
An elliptic model for space-time correlations in turbulent shear flows is proposed based on a second order approximation to the iso-correlation contours, while Taylor’s hypothesis implies a first-order approximation.

Model-Based Systems Engineering Cybersecurity for Space Systems [PDF]

open access: yes, 2023
As industries in various sectors increasingly adopt model-based systems engineering (MBSE) for system lifecycle design and development, engineers can manage and describe systems of higher complexity than ever before. This is especially true for the field

A solvable model of flat space holography

open access: yesJournal of High Energy Physics, 2023
We propose an explicit realization of flat space holography in two dimensions where both sides of the duality are independently defined and the boundary theory is completely solvable.

Extended Metabolic Space Modeling [PDF]

open access: yes, 2018
Determining the fraction of the chemical space that can be processed in vivo by using natural and synthetic biology devices is crucial for the development of advanced synthetic biology applications. The extended metabolic space is a coding system based on molecular signatures that enables the derivation of reaction rules for metabolic reactions and the

Architecture and Network Model of Time-Space Uninterrupted Space Information Network

open access: yesIEEE Access, 2019
Space information network (SIN) plays an extremely important role in civil and military applications. However, a specific definition of SIN still remains a challenging issue.
