![]() The first version of VMD for the Microsoft Windows platform was released in 1999. In 1998, John Stone became the main VMD developer, porting VMD to many other Unix operating systems and completing the first full-featured OpenGL version. Ulrich in 1995–1996, followed by Sergei Izrailev and J. The earliest versions of VMD were developed for Silicon Graphics workstations and could also run in a cave automatic virtual environment (CAVE) and communicate with a Nanoscale Molecular Dynamics ( NAMD) simulation. The initial version of VMD was written by William Humphrey, Andrew Dalke, Ken Hamer, Jon Leech, and James Phillips. A precursor program, called VRChem, was developed in 1992 by Mike Krogh, William Humphrey, and Rick Kufrin. VMD has been developed under the aegis of principal investigator Klaus Schulten in the Theoretical and Computational Biophysics group at the Beckman Institute for Advanced Science and Technology, University of Illinois at Urbana–Champaign. The VMD axes are shown as a simple example of rendering of non-molecular geometry. The Tachyon rendering uses both direct lighting and ambient occlusion lighting to improve the visibility of pockets and cavities. The scene is shown with a combination molecular surfaces colored by a radial distance, and nucleic acids shown in ribbon representations. History Satellite tobacco mosaic virus molecular graphics produced in VMD and rendered using Tachyon. VMD is available to non-commercial users under a distribution-specific license which permits both use of the program and modification of its source code, at no charge. VMD runs on Unix, Apple Mac macOS, and Microsoft Windows. Users can run their own Tcl and Python scripts within VMD as it includes embedded Tcl and Python interpreters. Molecular scenes can be exported to external rendering tools such as POV-Ray, RenderMan, Tachyon, Virtual Reality Modeling Language ( VRML), and many others. It also includes tools for working with volumetric data, sequence data, and arbitrary graphics objects. VMD is developed mainly as a tool to view and analyze the results of molecular dynamics simulations. Visual Molecular Dynamics ( VMD) is a molecular modelling and visualization computer program. Remember that you will need to be logged in with X forwarding or Thinlinc to make use of the interface.VMD visualization of a 1-billion atom aerosolized SARS-CoV-2 virion, rendered with Tachyon on a workstation with 1TB RAM. do a module load vmd/1.9.3-nsc1Īnd then issue the "vmd" command. The complete set of features can be found here.Īccess to the VMD binary is given via the module system, e.g. In particular, VMD can act as a graphical front end for an external MD program by displaying and animating a molecule undergoing simulation on a remote computer. VMD can be used to animate and analyze the trajectory of a molecular dynamics (MD) simulation. VMD provides a wide variety of methods for rendering and coloring a molecule: simple points and lines, CPK spheres and cylinders, licorice bonds, backbone tubes and ribbons, cartoon drawings, and others. It may be used to view more general molecules, as VMD can read standard Protein Data Bank (PDB) files and display the contained structure. VMD is designed for modeling, visualization, and analysis of biological systems such as proteins, nucleic acids, lipid bilayer assemblies, etc.

That said, if you want the surest possible path to a comfortable middlegame, the London System might be for you. London System chess Opening moves Step by Step. 3 The Elements in Motion 33 The elements are applied and analyzed in a famous game. If you play this opening, you’ll likely see the same sorts of middlegames and pawn structures again and again, and variety is important when developing your chess intuition and knowledge! Chess Openings and Book Moves - Openings Popular Openings All Openings 1. The appeal of such a system is obvious, but I generally don’t recommend the London to developing chess players. The London System is an easy-to-learn opening that promises white a comfortable game without much effort. Black’s pawns restrict this knight very well! Conclusion In rigid d4/d5 pawn structures (with no pawn tension and with neither player’s d-pawn being an isolated pawn), a knight on c3 is often misplaced. This move highlights the downsides of white’s knight being on c3. It’s not often correct to play a move like this in the opening instead of continuing with your piece development, but in this line it’s worth it for black to prevent white’s pieces from using the b5 square. ![]() Suppose you’re on the lookout for a unique tattoo design that’s bound to draw awareness and initiate conversations.

Point bars are found in abundance in mature or meandering streams. A point bar is a depositional feature made of alluvium that accumulates on the inside bend of streams and rivers below the slip-off slope. ![]() Material eroded here is deposited downstream in point bars. Not only are cut banks steep and unstable, they are also the area of a stream where the water is flowing the fastest at a higher pressure and often deeper, making them rather dangerous. Given enough time, the combination of erosion along cut banks and deposition along point bars can lead to the formation of an oxbow lake. Often, particularly during periods of high rainfall and higher-than average water levels, trees and poorly placed buildings can fall into the stream due to mass wasting events. Normally, cut banks are nearly vertical and often expose the roots of nearby plant life. Satellite image showing a meander with a cutbank on the external margin and a point bar in the internal margin of the water stream. This makes it easier for the river to evolve in its form within time and space as the horseshoes migrate through the erosional plain in a horizontal way rather than a vertical way, as shown below (4):įigure 7. Diagram that shows the relation between the river speed (Y axis), the particle size (X axis) and the total amount of particles eroded, transported and deposited.Īs meandered streams are mostly found in plains, the speed of the flow is not big enough so as to carry big sized particles, which explains why landforms found in this kind of water streams are composed by thin particles. ![]() The competence of a stream increases proportionally to the mathematical square of its speed (3).įigure 3. The key lays in the water speed fast water streams have a larger competence that the slower ones, despite the size of the water stream beds. By its competence: which measures the ability of a stream to transport particles according to the size of these, rather than the quantity which is carried away.Large rivers with high flow speeds have a major capacity. As larger the water that flows in the stream is, the higher its capacity to transport the sediment. By its capacity: which refers to the maximum amount of sediments that may be carried.The ability of a stream to transport particles can be described in two ways: Transportation of sediments through a water stream according to the size of particles. What's the matter? You couldn't find anybody who could sing? You're appearing on this album with Tierney, with Kurt Elling, with Niki Haris, with Melissa Manchester, and with your own sister. It's just a wonderful musical experience. Somehow when our voices blend it feels like two flutes that are dancing in the wind. Tierney and I did a show of songs from two albums about movies, that we toured around the country. Trey's arranging powers are exceptional, so it was a joy to work with them. She teases me about it, but yes, I think they are phenomenal musicians. Well, I actually was on the road with Tierney Sutton, and I've worked with that band since the ‘90s whenever I'm on the West Coast, and she's not working with them. I'm sure it's not the only reason, but it explains why you recorded this wonderful song with Tierney Sutton, because basically that was her band that you were working with, right? It was so nice to work with Christian and see him in person and make that music that is so beautiful when you're together in the same room. But I was amazed at how beautifully each song unfolded over the three years. So we were out and about, back in business, performing. The only time I got to be in the room with people was when I recorded my duet with Melissa Manchester when we were both in LA. It was the first time in my life that I got to work with people not in the room. We had beautiful sounds from their arranging too. Then we had various guests to other beautiful sounds. Trey Henry is the bass player, Ray Brinker did the drums and Brian Kilgore did percussion. I got to work with Christian Jacob, who was on piano. Speaking of which, I was really struck by the musicians that you have on the recording, not just the incredible special guests that you have on various selections. Working with some of my favorite musicians and singers, it was a real dream come true on many levels. I'm so happy that, over three years, I got to work with a genius team of Trey Henry and Paul Viapiano, who assembled a sonic universe to put my songs and bring them to life. This project began with a few singles, and it turned into an entire CD, the most songs I've ever recorded on one CD. There are so many things that are baffling. There are a lot of moments in this life, and I'm sure it will be ahead of us, where life feels very hard to believe in. I was really trying to lift people's spirits up and I was trying to find the beauty of life despite all the chaotic uncertainty that we were living with. It was a very rich, creative time when I wrote a poem every single day and shared it. What I've learned in my life, what matters to me, of all original songs was just the perfect expression of what I needed to do during the pandemic. But I thought, well, what is on my bucket list and what's at the top of it? Doing a record that is the most personal way of sharing how I see the world. And, like a great song, tomorrow may never come. We don't know what's going to happen tomorrow. I thought it was always kind of strange that I didn't do more of my original songs.ĭuring the pandemic, when this project began, I thought to myself, a lot of people are not with us anymore. But most of the singer songwriters, when I was just really discovering that this is what I wanted to do with my life, only did their own songs. The people inspired me to be a songwriter who I list as Joni Mitchell, Carole King, James Taylor, and then, George Gershwin's Rhapsody in Blue when I was seven. ![]() ![]() From Barbra Streisand to Liza Minnelli to Karrin Allyson to so many others.Īnn Hampton Callaway: Well, most of my favorite singer songwriters would only do their own songs. The list of people doing your songs is unbelievable. After having seen you numerous times celebrate the Great American Song Book, why now would you do this record of just your songs, admittedly with a variety of guests? You’ve always been a remarkable songwriter. (Spoiler alert: not all the inspiration comes from this world.)īrian Delp: It's a great pleasure for us to have you here to talk about your tremendous new album. Listen for the incredibly talented singers with whom she's collaborating, and the inspiration behind these beautiful songs. But did you know she is a prolific songwriter as well? She has usually included one or two of her own songs on her various albums over the years, but now she offers us Finding Beauty: Originals, Vol. ![]() When you hear Ann Hampton Callaway sing pages from the Great American Songbook you know that you're hearing one of the loveliest voices on the planet interpret the work of Gershwin, Porter, Mercer and Kern. |
