Surya is an open‑source, AI‑based foundation model for heliophysics developed collaboratively by NASA (via the IMPACT AI team) and IBM. Named after the Sanskrit word for “sun,” Surya is trained on nine years of high‑resolution solar imagery from NASA’s Solar Dynamics Observatory (SDO). It is designed to forecast solar phenomena—such as flares, solar wind, irradiance, and active region behavior—by predicting future solar images with a sophisticated long–short vision transformer architecture,...

Use this software as an user interface for the Hamamatsu C12880MA mini spectrometer connected to an Arduino board. The project details can be found in my github repository: https://github.com/luramire/OpenSpectra

This is a simulation package developed for numerical simulation of ultrashort pulse propagation in optical media and pulse generation from mode-locked lasers. Although the code is primarily intended for investigations of fiber links, fiber amplifiers and fiber lasers, it can be applied to any other setting for which the governing equiations are valid. The physics included in the code is based on a generalized nonlinear Schrödinger equation, including higher order dispersion, stimulated Raman...

Geophysical Library is a C++-library to handle geophysical data. At the moment the focus is on magnetotelluric and seismic data. It also includes a genetic algorithm for data inversion, signal processing and statistics routines.

This package of MATLAB routines with accompanying GUI allows scientific users to measure the 3D location of single molecules when using the double-helix point spread function (DH-PSF) widefield microscope. Version 2 also includes code that facilitates combining localization data from two spectral channels using a locally-weighted quadratic 3D registration function Features - Double-Gaussian estimator is calibrated via an axial scan of bright immobile fluorescent emitters (e.g. beads) - DH localization is performed through template matching and subsequent double Gaussian fitting - Tiff stacks of SM images are analyzed using template matching followed by double-Gaussian fitting to extract estimates of the molecule positions - Two spectral channels are registered by generating a locally-weighted quadratic mapping function from control point pairs

The Gecko Hamaker open-source software project is a full implementation of the fully retarded Lifshitz formulations for isotropic and anisotropic plane-plane and cylinder-cylinder interactions with intervening interlayer materials, planar systems of up to 99 layers, and graded interfaces for the modeling of grain boundaries or other continuously changing systems, accompanied by a database of material optical properties spectra. The machine-readable optical property database is available for download and as a web service and makes available the full spectral optical properties of over 150 materials from both ab initio calculations and experimental measurements.

This is a set of spectral models for use in the astronomical X-ray spectral modeling program XSPEC. The models calculate X-ray emission line Doppler profiles from the winds of OB stars.

SpecMark (spectral Markov) is a method for calculating the joint probability distribution over species in a regulatory network.
