Materials Discovery: GNoME
AI discovers 520000 stable inorganic crystal structures for research
Materials Discovery (GNoME) is a large-scale research initiative by Google DeepMind focused on applying graph neural networks to accelerate the discovery of stable inorganic crystal materials. The project centers on Graph Networks for Materials Exploration (GNoME), a message-passing neural network architecture trained on density functional theory (DFT) data to predict material stability and energy formation. Using GNoME, DeepMind identified 381,000 new stable materials, later expanding the dataset to include over 520,000 materials within 1 meV/atom of the convex hull as of August 2024. The repository provides datasets, model definitions, and interactive Colabs for exploring these materials, computing decomposition energies, and visualizing chemical families. ... -

PerfectSineWaves
Perfect and bit-perfect PCM encoded sine wave audio test tones
In this project, a perfect PCM sine wave is one that contains a single frequency at 0 dBTP and no error harmonics at all. A bit-perfect PCM sine wave has error harmonics due to encoding quantization, but they are at the minimum level possible for the chosen encoding. The generated wave files hold a sequence of one or more complete copies of a repeating pattern. A file containing a single pattern can be played in a loop to extend the play time. Because most audio players don't loop... -

TRACK code
Code for finding the transport properties using Kubo formalism.
...It is developed to calculate the temperature dependent transport properties (electrical conductivity, electronic part of thermal conductivity, Seebeck coefficient and Lorenz number) of different class of materials (e.g. correlated material) using the Kubo linear-response formalism. This method is implemented for estimating the transport properties using interacting (DFT+DMFT) and non-interacting (DFT) electronic structure methods. It is possible to use the relaxation time approximation in this code with the eigenvalues of DFT method. In present version, the code is interfaced with WIEN2k and eDMFTF codes. Please cite the paper mentioned below while using the TRACK code for your research. A. ... -

ppienergy
Compute Protein Protein Interaction Energy Profile
Protein-protein interactions (PPIs) are crucial for understanding the signaling and disease mechanisms in a cell. In the present work, we have developed a new approach to explore the energy landscape of protein-protein interactions by employing a rapid modified DFT-D approach using the atomic coordinates obtained from X-ray and NMR spectroscopy data. The distance energy plots of contact residues in the interacting regions of several experimentally validated protein-protein complexes were computed to generate energy landscapes. Cumulative energy profiles of protein-protein complexes were generated for observing trends in the context of geometry (parallel, terminal), surface areas (large, medium, small) and interacting partners (homomer, heteromer). -

CQT-FW
CQT-FW is an audio analisys tool for multiple pitch recognition
...In CQT-FW we have the same frequency resolution as CQT, but with fixed length windows in time, what leads to a constant time resolution as well. And more, time and frequency resolution are not dependent like in CQT end DFT transforms. We also propose a post processing witch eliminate the high order harmonics, leaving only the fundamental frequencies. The transform got good results in a good range of frequencies, but still have problems in low frequencies. -
