Surya
Implementation of the Surya Foundation Model for Heliophysics
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,... -

Raman Data Search and Storage
A Raman spectra library with search and storage function.
...Besides the search utility by the Raman band positions, which was proven to be priceless in the interpretation of Raman spectra, the RDSS software gives the user the ability to display and inspect the Raman spectra quickly and very efficiently. Users can zoom into the Raman spectrum, shift in any direction the wavenumber and the intensity axes, and if any part of the spectral display is clicked, that region will be highlighted and the specific wavenumber returned. A photo for every sample entry stored in the database is also available. -

easy-dhpsf
GUI for fitting 3D single-molecule images using the double-helix PSF
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 -

JSpecView Project
Spectroscopy Viewer
The JSpecView Project initially provided JAVA applets for the display of JCAMP-DX and AnIML/CML spectral files. The source and binary files are available via the Code (sourceforge SVN) and Files menu options. See the WIKI pages (Hosted Apps) for more detail. Beginning September 2018 all code changes are being handled via the Jmol Sourceforge page. The codes has been fully merged and JSmol the JavaScript/HTML5 version of Jmol now includes the non-Java version of JSpecView. -
