An ensemble approach using multidimensional convolutional neural networks in wavelet domain for schizophrenia classification from sMRI data
The sMRI scans are stacked together and presented in .nii file format for each subject. A certain number of initial and final images do not contain enough details; hence those images are omitted from further processing. The MDCNNs are trained by…

Geometry based prediction of tau protein sites and motifs associated with misfolding and aggregation
In this work, we analyze local structures of tau filaments of tauopathies using the Writhe and the LTE. We also introduce and use the Repeat Topological Free Energy (RTE) and the Peptide Topological Free Energy (PTE). Based on the local…

Image preprocessing to enhance phase correlation of featureless images
Phase correlation has endured since its introduction in 1975 by Kuglin and Hines1. Though applications have been broad, improvements to the technique have been very limited. Surprisingly few efforts have been published regarding improved phase…

A simple way to boost math progress
American students have been falling behind in math for decades — with test scores that consistently rank in the bottom 25% globally compared to students in other developed countries — and the COVID-19 pandemic made the situation worse.
Previous…

Mathematicians uncover the logic behind how people walk in crowds
Next time you cross a crowded plaza, crosswalk, or airport concourse, take note of the pedestrian flow. Are people walking in orderly lanes, single-file, to their respective destinations? Or is it a haphazard tangle of personal trajectories, as…
