It is similar to the CrystalStructure.m package, which is a representation of the diamond lattice. These packages were partly inspired by the clarity with which CrystalStructure.m renders the diamond lattice, when the final output is generated PostScript, and the desire to rotate the crystal structure and view it from different angles to look for symmetry planes, etc. Basically these models are alternatives to ball-and-stick type models. 0011: GaAsNotebook.ma Mathematica notebook (February 1992; 73 kilobytes) 0022: GaAs1.m Mathematica package (February 1992; 2 kilobytes) 0033: GaAs2.m Mathematica package (February 1992; 3 kilobytes) 0044: GaAs3.m Mathematica package (February 1992; 4 kilobytes) 0055: GaAs4.m Mathematica package (February 1992; 4 kilobytes) 0066: GaAs5.m Mathematica package (February 1992; 6 kilobytes) 0077: GaAs6.m Mathematica package (February 1992; 6 kilobytes) 0088: GaAs7.m Mathematica package (February 1992; 6 kilobytes) 0099: GaAs-README.txt documentation (February 1992; 5 kilobytes) 0206-648: Movies of Molecular Model Vibrations (May 10, 1994) Author: W. Martin McClain Normal modes of molecular vibration lie at the heart of understanding the absorption of infrared light by molecules. These notebooks were developed to accompany an undergraduate laboratory experiment. Students spend one week using the infrared spectrometer, and two weeks understanding the theory, as presented in the notebooks. The molecular model is a spring-and-ball model, and it uses only Hooke's Law for the springs and Newton's Third Law for the balls. The problem is transformed to an eigenproblem, solved, and the solution is transformed back to the spring-and-ball space. It is then easy to produce a movie of the molecular motion, starting from any desired initial conditions. We show pseudorotation of a ring molecule, a motion that cannot be foreseen intuitively. 1994 Mathematica Developer Conference, Champaign, Illinois. 0011: 1-TriangleNormalModes.ma Mathematica notebook (April 29, 1994; 225 kilobytes) 0022: 2-TriangleMovies.ma Mathematica notebook (April 29, 1994; 61 kilobytes) 0204-657: Schroedinger's Equation (March 1993) Author: Terry Robb Schroedinger's equation is numerically solved by calling an external subroutine from within Mathematica. By importing the Fortran subroutine (named SCHROED, which implements a Crank-Nicholson scheme) using InterCall, it is possible to do various experiments -- for example shooting a wave-packet at a potential barrier and watching an animation of the packet being mostly reflected but also partially tunnelling through the wall. The potential function V[x,t], required by the Fortran SCHROED routine, can be written as a Mathematica function which gives a lot of flexibility for interactive experimentation. This notebook demonstrates one such experiment. 0011: schroed.ma Mathematica notebook (March 1993; 792 kilobytes) 0202-622: Lie Symmetries (March 1993) Author: Gerd Baumann The purpose of this program is to derive the determining equations for Lie-point symmetries. The determining equations are derived in a form simplified as far as possible. The program allows an automatic solution of the determining equations by using a polynomial ansatz in the dependent and independent variables. If the infinitesimals (symmetries) of the symmetry transformation is known, a classification of the related Lie-algebra is possible. The Lie-algebra is directly related to the symmetry group of the equations that can be used to construct an explicit solution of the equations of motion considered. Lie's symmetry method is usable to construct solutions for linear and especially for nonlinear systems of differential equations. The program also provides a classification of the Lie-algebra by derived algebras. 0011: lie.m Mathematica package (March 1993; 68 kilobytes) 0022: Documentation.ps PostScript documentation for lie.m (March 1993; 373 kilobytes) 0203-397: Crystal Animations Resulting from Molecular Dynamics Calculations (July 1992) Author: Kazume Nishidate Mathematica gives us a very useful and simple way to visualize Molecular Dynamics (MD) simulations. Mathematica is used to animate the motion of ions from the results of MD calculations produced by the ANRZR2 and MXDORTO programs, written by K. Nishidate and K. Kawamura, respectively. These notebooks allow us to "look" at the dynamic motion of ions within a crystal from the results of MD calculation. There are many advantages to using Mathematica to analyze the MD simlation. For example, we can easily view not only the animation of crystals, but also the graphics of trajectory of atoms over the MD simulation. Utilizing the graphics object in animation notebooks, stereoscopic views and projections of crystals can also be obtained . 0011: README.txt Author's notes (July 1992; 5 kilobytes) 0022: NaCl.ma Mathematica notebook (July 1992; 72 kilobytes) 0033: KCl.ma Mathematica notebook (July 1992; 72 kilobytes) 0044: MgF2.ma Mathematica notebook (July 1992; 117 kilobytes) 0055: CaF2.ma Mathematica notebook (July 1992; 68 kilobytes) 0066: Perovskite.ma Mathematica notebook (July 1992; 75 kilobytes) 0077: Quartz.ma Mathematica notebook (July 1992; 32 kilobytes) 0088: QuartzProjection.ma Mathematica notebook (July 1992; 32 kilobytes) 0099: QuartzStero.ma Mathematica notebook (July 1992; 27 kilobytes) 0206-031: Linear Lattice-Ligand Binding Notebooks (February 18, 1994) Author: Alan R. Wolfe These Mathematica notebooks calculate and plot data for the binding of ligands to an infinite linear lattice. Binding site overlap and cooperative interactions between adjacent bound ligands are taken into account. This is a mathematical model for non-sequence-selective binding of proteins and other small molecules (ligands) to a linear macromolecule such as DNA (the lattice). The method is based on the treatment given in Wolfe, A. R. and Meehan, T.

Colquhoun and A.G. Hawkes, Proc. R. Soc. Lond. B 199, 231-262 (1977). Assuming a discrete state, continuous time Markov model for the behavior of ligand-gated ion channels, and given the transition rate constants between these states, the time evolution of their occupancy can be computed. This occupancy is then used to predict observables like the mean transmembrane current and its coefficient of variation. ColquhounHawkes.m numerically integrates the occupancy equation, which allows for arbitrary transmitter concentration functions of time. ColquhounHawkesMC.m performs a Monte Carlo simulation of the channel state transitions. In order to be fast, it uses some C routines via MathLink. 0011: README.txt Introduction and file descriptions (930419; 3 kilobytes) 0022: Manual.ma Documentation notebook, read this first (930419; 659 kilobytes) 0033: DiagramToQMatrix.m Builds the transition rate matrix (921201; 6 kilobytes) 0044: ColquhounHawkes.m Numerically solves the occupancy ODE (930201; 10 kilobytes) 0055: ColquhounHawkesMC.m Package for Monte Carlo simulation (930201; 33 kilobytes) 0066: chmc.tm MathLink templates and C routines for MC sim.
