Eigenvectors of random matrices: A survey [PDF]

open access: yes, 2016
Eigenvectors of large matrices (and graphs) play an essential role in combinatorics and theoretical computer science. The goal of this survey is to provide an up-to-date account on properties of eigenvectors when the matrix (or graph) is random.Comment ...

Normal Functions as a New Way of Defining Computable Functions [PDF]

open access: yesComputer Science, 2004
Report sets new method of defining computable functions. This is formalization of traditional function descriptions, so it allows to define functions in very intuitive way.

A Model of Fast Hebbian Spike Latency Normalization

open access: yesFrontiers in Computational Neuroscience, 2017
Hebbian changes of excitatory synapses are driven by and enhance correlations between pre- and postsynaptic neuronal activations, forming a positive feedback loop that can lead to instability in simulated neural networks.

Revisiting the Minimum Breakpoint Linearization Problem Theoretical Computer Science [PDF]

open access: green, 2013
International audienceThe gene order on a chromosome is a necessary data for most comparative genomics studies, but in many cases only partial orders can be obtained by cur- rent genetic mapping techniques.

Generating Turing Machines by Use of Other Computation Models [PDF]

open access: yesComputer Science, 2003
For each problem that can be solved there exists algorithm, which can be described with a program of Turing machine. Because this is very simple model programs tend to be very complicated and hard to analyse by human.

A Hippocampal Model for Behavioral Time Acquisition and Fast Bidirectional Replay of Spatio-Temporal Memory Sequences

open access: yesFrontiers in Neuroscience, 2018
The hippocampus is known to play a crucial role in the formation of long-term memory. For this, fast replays of previously experienced activities during sleep or after reward experiences are believed to be crucial.

Computational Complexity in Electronic Structure [PDF]

open access: yes, 2012
In quantum chemistry, the price paid by all known efficient model chemistries is either the truncation of the Hilbert space or uncontrolled approximations.

Specifying and Verifying Properties of Space - Extended Version [PDF]

open access: yes, 2014
The interplay between process behaviour and spatial aspects of computation has become more and more relevant in Computer Science, especially in the field of collective adaptive systems, but also, more generally, when dealing with systems distributed in ...
