Neurons in primary visual cortex of many mammals are clustered according to their preference to stimulus parameters such as orientation and spatial frequency. Nevertheless, responses to complex visual stimuli are highly heterogeneous between adjacent neurons. To investigate the relation between these observations, we recorded from pairs of neighboring neurons in area 17 of anesthetized cats in ...

Many works have demonstrated that the performance of the prediction error (PE) based reversible watermarking algorithm depends on the precision of the prediction value. However, most algorithms compute the prediction value by exploiting only the correlation between the embedding pixel and its neighboring pixels, thus limiting the watermarking performance of these algorithms. In this work, we ob...

Motivation Genomics features with similar genome-wide distributions are generally hypothesized to be functionally related, for example, colocalization of histones and transcription start sites indicate chromatin regulation of transcription factor activity. Therefore, statistical algorithms to perform spatial, genome-wide correlation among genomic features are required. Results Here, we propos...

The bias of nucleotide substitutions in noncoding sequences of the plant chloroplast genome is strongly dependent on the composition of the two flanking bases. Substitutions in G+C-rich environments have a strong bias toward transitions, while in A+T-rich environments, transversions outnumber transitions. In this study, the correlation between the composition of neighboring bases and nucleotide...

The region of northeastern France is affected by low-magnitude background seismicity, with the rare occurrence moderate earthquakes, which gives this a non-negligible seismic risk. We provide an overview seismicity and seismotectonics intraplate domain its sub-regions: Upper-Rhine Graben (URG), external range foreland Jura, Vosges, northern southern Belgium. Previously published catalogues over...
