Hairpin-based state machine and conformational addressing: Design and experiment
Springer Science and Business Media LLC - Tập 4 - Trang 103-126 - 2005
In this paper, we propose a new architecture for a multi-state DNA machine whose
conformation of repeated hairpin structures changes sequentially in response to
input oligomers. As an application of the machine, we also propose molecular
memory in which the machine is used as a memory unit. Addressing in the memory
is realized through state transitions of the machine. We then describe a method
for...
Distance-based affective states in cellular automata pedestrian simulation
Springer Science and Business Media LLC - - Trang 1-13
Cellular Automata have successfully been successfully applied to the modeling
and simulation of pedestrian and crowd dynamics. In particular, the investigated
scenarios have often been focused on the evaluation of medium–high population
density situations, in which the motivation of pedestrians to reach a certain
location overcomes their tendency to naturally respect proxemic distances. The
global...
On string languages generated by spiking neural P systems with exhaustive use of rules
Springer Science and Business Media LLC - Tập 7 - Trang 535-549 - 2008
We continue the study of (extended) spiking neural P systems with exhaustive use
of rules by considering these computing devices as language generators.
Specifically, a step is associated with a symbol according to the number of
spikes emitted by the output neuron and the sequence of these symbols associated
with a halting computation constitutes a string. Two cases are considered: one
of them int...
Cellular automata-based systems with fault-tolerance
Springer Science and Business Media LLC - Tập 11 - Trang 673-685 - 2012
One of the new computing paradigms which could overcome some of the problems of
existing computing architectures may be cellular computing. In the investigated
scenario, cellular automata-based systems are intended for yet-unknown methods
of fabrication and as such, they need to address the problem of fault-tolerance
in a way which is not tightly connected to used technology. Our goal is to reach
...

Comparison of synchronous and asynchronous parallelization of extreme surrogate-assisted multi-objective evolutionary algorithm
Springer Science and Business Media LLC - - 2022
AbstractThis paper investigates the integration of a surrogate-assisted
multi-objective evolutionary algorithm (MOEA) and a parallel computation scheme
to reduce the computing time until obtaining the optimal solutions in
evolutionary algorithms (EAs). A surrogate-assisted MOEA solves multi-objective
optimization problems while estimating the evaluation of solutions with a
surrogate function. A su...
Lattice-based versus lattice-free individual-based models: impact on coexistence in competitive communities
Springer Science and Business Media LLC - Tập 18 - Trang 855-864 - 2019
Individual-based modelling is an increasingly popular framework for modelling
biological systems. Many of these models represent space as a lattice, thus
imposing unrealistic limitations on the movement of the modelled individuals. We
adapt an existing model of three competing species by using a lattice-free
approach, thereby improving the realism of the spatial dynamics. We retrieve the
same qual...
A multi-objective feature selection method based on bacterial foraging optimization
Springer Science and Business Media LLC - Tập 20 - Trang 63-76 - 2019
Feature selection plays an important role in data preprocessing. The aim of
feature selection is to recognize and remove redundant or irrelevant features.
The key issue is to use as few features as possible to achieve the lowest
classification error rate. This paper formulates feature selection as a
multi-objective problem. In order to address feature selection problem, this
paper uses the multi-o...
Physical modeling of biomolecular computers: Models, limitations, and experimental validation
Springer Science and Business Media LLC - - 2004
A principal challenge facing the development and scaling of biomolecular
computers is the design of physically well-motivated, experimentally validated
simulation tools. In particular, accurate simulations of computational behavior
are needed to establish the feasibility of new architectures, and to guide
process implementation, by aiding strand design. Key issues accompanying
simulator developmen...
