Aperiodic Oscillation Structured by Lossless Circuit

Slow oscillation circuit of the intergeniculate leaflet.

The slow oscillation circuit of the intergeniculate leaflet seems to constitute a natural basic rhythm of the neuronal mechanism of mammalian biological clock. The results of studies conducted so far indicate that photic information flowing from ganglion cells of the retina is necessary for its generation. On the other hand, this circuit is maintained thanks to the oscillatory activity of GABAe...

Lossless Microarray Image Compression by Hardware Array Compactor

Microarray technology is a new and powerful tool for concurrent monitoring of large number of genes expressions. Each microarray experiment produces hundreds of images. Each digital image requires a large storage space. Hence, real-time processing of these images and transmission of them necessitates efficient and custom-made lossless compression schemes. In this paper, we offer a new archi...

Piecewise Linear Tree-Structured Models for Lossless Image Compression

This paper presents a probabilistic model for use in lossless image compres-sors. For each pixel the model provides a conditional distribution, which in the most simple case is a discretized gaussian. The mean and variance of this gaus-sian are determined by using that pixel's neighbors to search a tree to nd an autoregressive model, which is then applied to those same neighbors. Finally, an ar...

Structured Grammar-based Codes for Universal Lossless Data Compression∗

A grammar-based code losslessly compresses each finite-alphabet data string x by compressing a context-free grammar Gx which represents x in the sense that the language of Gx is {x}. In an earlier paper, we showed that if the grammar Gx is a type of grammar called irreducible grammar for every data string x, then the resulting grammar-based code has maximal redundancy/sample O(log log n/ log n)...
