Features:

• Store images exported from your PACS system.
• Drag and drop cases directly from OsiriX.
• Browse by system, pathology and region.
• Make smart and simple albums.
• Display in full screen mode.
• Create Keynote presentations.
• Query, import to and export from MIRC sites.

Math Page Generator can randomly create arithmetic and algebra practice pages that you can easily print and use for practice or testing purposes.
Each type of problem (Addition, Subtraction, Multiplication, and Algebra) comes with three difficulty options.

FractionAction converts between rational fractions, decimals (with periodicity) and simple continued fractions within program’s computational limits. Also shows factors for fraction’s top and bottom (in reduced form with GCD [greatest common divisor]). Results not guaranteed (i.e. don’t use results to help build your rocket ship, etc.): reports of errors welcomed. Not a tutorial on the functions.

Quantum GIS (QGIS) is a user friendly Open Source Geographic Information System (GIS) that runs on Mac OS X, Linux, Unix, and Windows. QGIS supports vector, raster, and database formats. QGIS is licensed under the GNU General Public License. QGIS lets you browse and create map data on your computer. It supports many common spatial data formats (e.g. ESRI ShapeFile, geotiff). QGIS supports plugins to do things like display tracks from your GPS. QGIS is Open Source software and its free of cost. We welcome contributions from our user community in the form of code contributions, bug fixes, bug reports, contributed documentation, advocacy and supporting other users on our mailing lists and forums. Financial contributions are also welcome.

MacMolPlt is a Chemistry visualization tool that can be used to build molecules with an integrated graphical model builder, create input files for the GAMESS computational chemistry program, and then visualize the results of computational chemistry runs. Features include a high-quality 3D display, animations of normal modes and reaction sequences and output to a variety of formats including high-quality images and QuickTime and Flash movies.

* Input using:
o MolPlt file format punched out by GAMESS
o by pasting in Cartesian coordinates from any GAMESS or Gaussian log file
o any GAMESS input, log or irc file
o Xmol style XYZ file
o MolDen format files
o Protein Data Bank (pdb) file
o Chemical Markup Language (CML) files
o Build graphically with an interactive molecule editor
o Build by hand using cartesian or Z-Matrix style internal coordinates
* 3D display of structure and Normal mode
* Animation of Normal modes.
* 3D real-time rotation and translation under mouse control
* Calculation of any Z-matrix parameter
* Visually measure/display distances, angles and dihedrals.
* Automated creation of Linear Least Motion (LLM) paths
* 2D and 3D calculation and display of:
o Molecular orbitals (AO’s, MO’s, or LMO’s)
o Total Electron Density
o Density differences
o Molecular Electrostatic Potentials (MEPMaps)
* Basic input file generator for GAMESS
* OpenGL used for high-quality 3D rendering
* Support for molecular symmetry
o Generate symmetry dependant atoms

IMPORTANT NEWS!:

* Until recently, 3D-XplorMath was a Macintosh only application. However, Professor David Eck of Hobart and William Smith Colleges has created a cross-platform Java version called 3D-XplorMath-J. While this version is still lacking a number of Exhibits and features of its older Pascal sister, it is rapidly catching up, and is already ready for serious use. Our goal is for it to eventually include all the essential functionality of the Pascal version. The latest development version of 3D-XplorMath-J is available for download at http://3D-XplorMath.org/j
* Gale Paeper has been working over the past year to make the Pascal version of 3D-XplorMath compatible with a new Pascal Compiler (GPC). When this work is complete, probably sometime in Fall 2007, it will make it possible to generate a 3D-XplorMath Universal Binary version that will run native on Intel-based Macs as well as on PowerPC Macs. (3D-XplorMath version 10.5 runs using Rossetta emulation on Intel-based Macs, resulting in slightly slower performance for some operations.)

3D-XplorMath (formerly 3D-Filmstrip) is a highly interactive museum for exploring the visual aspects of the exciting and beautiful universe of mathematical objects and processes. It has been under continual development for over fifteen years by an international team of renowned mathematical researchers and educators, the 3DXM Consortium. It was originally developed for use in teaching and research, but recently the Consortium has been working hard to make it easy and enjoyable to use by anyone with mathematical curiosity and an appreciation for the visual and logical beauty of mathematics.

This museum contains literally hundreds of well-known (and some not so well-known) mathematical objects, arranged logically into numerous “galleries”, referred to as Categories. These include: Surfaces, Planar Curves, Space Curves, Polyhedra, Conformal Maps, Dynamical Systems, Waves, and (the latest) Fractals & Chaos. The “3D” in its name refers to the fact that 3D objects can be viewed in strikingly realistic stereo.

If you would like to visit a Gallery of just some of the remarkable surfaces that can be created and manipulated with the program, go to http://VirtualMathMuseum.org

3D-XplorMath differs from programs such as Mathematica, Maple, and Matlab that provide visualization back-ends for viewing objects, but require the user to first program the object and its visualization. 3D-XplorMath emphasizes ease of use and does not even require the user to have a pre-existing knowledge of the mathematical definition of an object in order to see it. Every mathematical object in its massive collection is not only pre-programmed, but also has carefully chosen default parameters and associated animations. Merely selecting a gallery object by its name from a menu presents an excellent initial view of the object. The user may then optionally use simple dialogs, controls, and menu choices to customize and animate this default view, perhaps after first learning about its background by choosing About This Object from the Documentation menu. Users can also create and animate new objects on their own by entering simple algebraic formulas into dialogs. All objects including user defined objects can be saved in several graphic formats, and animations can be saved as Quicktime movies.

Please send us reports of any difficulties you have with the program and any suggestions you have for new mathematical objects or for improving the user interface and the documentation. Either send email to palais@uci.edu or if you prefer write your comments as a VersionTracker review.
