Gray matter axonal connectivity maps. [PDF]
Frontiers in Psychiatry, 2015 Structural brain connectivity is generally assessed through methods that rely on pre-defined regions of interest (e.g. Brodmann’s areas), thus preventing analyses that are largely free from a-priori anatomical assumptions.

Using high angular resolution diffusion imaging data to discriminate cortical regions. [PDF]
PLoS ONE, 2013 Brodmann's 100-year-old summary map has been widely used for cortical localization in neuroscience. There is a pressing need to update this map using non-invasive, high-resolution and reproducible data, in a way that captures individual variability.

DNA Code from Cyclic and Skew Cyclic Codes over
Entropy, 2023 The main motivation of this work is to study and obtain some reversible and DNA codes of length n with better parameters. Here, we first investigate the structure of cyclic and skew cyclic codes over the chain ring R:=F4[v]/⟨v3⟩.

Self-Dual Cyclic Codes Over M2(ℤ4)
Discussiones Mathematicae - General Algebra and Applications, 2022 In this paper, we study the structure of cyclic codes overM2(ℤ4) (the matrix ring of matrices of order 2 over ℤ4), which is perhaps the first time that the ring is considered as a code alphabet.

SAR Image Segmentation Based on Fisher Vector Superpixel Generation and Label Revision
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 This article addresses the problem of superpixel-bases segmentation of synthetic aperture radar (SAR) images. Most superpixel segmentation methods have difficulties in segmenting adjacent regions with similar gray values, due to only considering spatial ...
