Classification of Influenza Hemagglutinin Protein Sequences using Convolutional Neural Networks

1 code implementation9 Aug 2021 Charalambos Chrysostomou, Floris Alexandrou, Mihalis A. Nicolaou, Huseyin Seker

This paper focuses on accurately predicting if an Influenza type A virus can infect specific hosts, and more specifically, Human, Avian and Swine hosts, using only the protein sequence of the HA gene.

Sinogram Denoise Based on Generative Adversarial Networks

no code implementations9 Aug 2021 Charalambos Chrysostomou

Finally, to demonstrate the efficacy and capability of the proposed method results from real-world DAT-SPECT sinograms are presented.

Deep Convolutional Neural Network for Low Projection SPECT Imaging Reconstruction

no code implementations9 Aug 2021 Charalambos Chrysostomou, Loizos Koutsantonis, Christos Lemesios, Costas N. Papanicolas

In this paper, we present a novel method for tomographic image reconstruction in SPECT imaging with a low number of projections.

SPECT Angle Interpolation Based on Deep Learning Methodologies

no code implementations9 Aug 2021 Charalambos Chrysostomou, Loizos Koutsantonis, Christos Lemesios, Costas N. Papanicolas

For evaluation of the efficacy of the method, phantoms based on Shepp Logan, with various noise levels added were used, and the resulting interpolated sinograms are reconstructed using Ordered Subset Expectation Maximization (OSEM) and compared to the reconstructions of the original sinograms.

Prediction of Influenza A virus infections in humans using an Artificial Neural Network learning approach

no code implementations12 Feb 2021 Charalambos Chrysostomou, Harris Partaourides, Huseyin Seker

In this paper, to accurately predict if an Influenza type A virus has the capability to infect human hosts, by using only the HA gene, is therefore developed and tested.

Unsupervised identification of the phase transition on the 2D-Ising model

1 code implementation8 Mar 2019 Constantia Alexandrou, Andreas Athenodorou, Charalambos Chrysostomou, Srijit Paul

We study numerically the relation between one latent dimension extracted from the autoencoder to the critical temperature $T_c$.
