Stem Trace: an interactive visual tool for comparative RNA structure analysis. (1/2878)

MOTIVATION: Stem Trace is one of the latest tools available in STRUCTURELAB, an RNA structure analysis computer workbench. The paradigm used in STRUCTURELAB views RNA structure determination as a problem of dealing with a database of a large number of computationally generated structures. Stem Trace provides the capability to analyze this data set in a novel, visually driven, interactive and exploratory way. In addition to providing graphs at a high level of ion, it is also connected with complementary visualization tools which provide orthogonal views of the same data, as well as drawing of structures represented by a stem trace. Thus, on top of being an analysis tool, Stem Trace is a graphical user interface to an RNA structural information database. RESULTS: We illustrate Stem Trace's capabilities with several examples of the analysis of RNA folding data performed on 24 strains of HIV-1, HIV-2 and SIV sequences around the HIV dimerization region. This dimer linkage site has been found to play a role in encapsidation, reverse transcription, recombination, and inhibition of translation. Our examples show how Stem Trace elucidates preservation of structures in this region across the various strains of HIV. AVAILABILITY: The program can be made available upon request. It runs on SUN, SGI and DEC (Compaq) Unix workstations.  (+info)

E-CELL: software environment for whole-cell simulation. (2/2878)

MOTIVATION: Genome sequencing projects and further systematic functional analyses of complete gene sets are producing an unprecedented mass of molecular information for a wide range of model organisms. This provides us with a detailed account of the cell with which we may begin to build models for simulating intracellular molecular processes to predict the dynamic behavior of living cells. Previous work in biochemical and genetic simulation has isolated well-characterized pathways for detailed analysis, but methods for building integrative models of the cell that incorporate gene regulation, metabolism and signaling have not been established. We, therefore, were motivated to develop a software environment for building such integrative models based on gene sets, and running simulations to conduct experiments in silico. RESULTS: E-CELL, a modeling and simulation environment for biochemical and genetic processes, has been developed. The E-CELL system allows a user to define functions of proteins, protein-protein interactions, protein-DNA interactions, regulation of gene expression and other features of cellular metabolism, as a set of reaction rules. E-CELL simulates cell behavior by numerically integrating the differential equations described implicitly in these reaction rules. The user can observe, through a computer display, dynamic changes in concentrations of proteins, protein complexes and other chemical compounds in the cell. Using this software, we constructed a model of a hypothetical cell with only 127 genes sufficient for transcription, translation, energy production and phospholipid synthesis. Most of the genes are taken from Mycoplasma genitalium, the organism having the smallest known chromosome, whose complete 580 kb genome sequence was determined at TIGR in 1995. We discuss future applications of the E-CELL system with special respect to genome engineering. AVAILABILITY: The E-CELL software is available upon request. SUPPLEMENTARY INFORMATION: The complete list of rules of the developed cell model with kinetic parameters can be obtained via our web site at: http://e-cell.org/.  (+info)

The high-resolution crystal structure of the molybdate-dependent transcriptional regulator (ModE) from Escherichia coli: a novel combination of domain folds. (3/2878)

The molybdate-dependent transcriptional regulator (ModE) from Escherichia coli functions as a sensor of molybdate concentration and a regulator for transcription of operons involved in the uptake and utilization of the essential element, molybdenum. We have determined the structure of ModE using multi-wavelength anomalous dispersion. Selenomethionyl and native ModE models are refined to 1. 75 and 2.1 A, respectively and describe the architecture and structural detail of a complete transcriptional regulator. ModE is a homodimer and each subunit comprises N- and C-terminal domains. The N-terminal domain carries a winged helix-turn-helix motif for binding to DNA and is primarily responsible for ModE dimerization. The C-terminal domain contains the molybdate-binding site and residues implicated in binding the oxyanion are identified. This domain is divided into sub-domains a and b which have similar folds, although the organization of secondary structure elements varies. The sub-domain fold is related to the oligomer binding-fold and similar to that of the subunits of several toxins which are involved in extensive protein-protein interactions. This suggests a role for the C-terminal domain in the formation of the ModE-protein-DNA complexes necessary to regulate transcription. Modelling of ModE interacting with DNA suggests that a large distortion of DNA is not necessary for complex formation.  (+info)

X-ray structure of T4 endonuclease VII: a DNA junction resolvase with a novel fold and unusual domain-swapped dimer architecture. (4/2878)

Phage T4 endonuclease VII (Endo VII), the first enzyme shown to resolve Holliday junctions, recognizes a broad spectrum of DNA substrates ranging from branched DNAs to single base mismatches. We have determined the crystal structures of the Ca2+-bound wild-type and the inactive N62D mutant enzymes at 2.4 and 2.1 A, respectively. The Endo VII monomers form an elongated, highly intertwined molecular dimer exhibiting extreme domain swapping. The major dimerization elements are two pairs of antiparallel helices forming a novel 'four-helix cross' motif. The unique monomer fold, almost completely lacking beta-sheet structure and containing a zinc ion tetrahedrally coordinated to four cysteines, does not resemble any of the known junction-resolving enzymes, including the Escherichia coli RuvC and lambda integrase-type recombinases. The S-shaped dimer has two 'binding bays' separated by approximately 25 A which are lined by positively charged residues and contain near their base residues known to be essential for activity. These include Asp40 and Asn62, which function as ligands for the bound calcium ions. A pronounced bipolar charge distribution suggests that branched DNA substrates bind to the positively charged face with the scissile phosphates located near the divalent cations. A model for the complex with a four-way DNA junction is presented.  (+info)

The three-dimensional structure of the RNA-binding domain of ribosomal protein L2; a protein at the peptidyl transferase center of the ribosome. (5/2878)

Ribosomal protein L2 is the largest protein component in the ribosome. It is located at or near the peptidyl transferase center and has been a prime candidate for the peptidyl transferase activity. It binds directly to 23S rRNA and plays a crucial role in its assembly. The three-dimensional structure of the RNA-binding domain of L2 from Bacillus stearothermophilus has been determined at 2.3 A resolution by X-ray crystallography using the selenomethionyl MAD method. The RNA-binding domain of L2 consists of two recurring motifs of approximately 70 residues each. The N-terminal domain (positions 60-130) is homologous to the OB-fold, and the C-terminal domain (positions 131-201) is homologous to the SH3-like barrel. Residues Arg86 and Arg155, which have been identified by mutation experiments to be involved in the 23S rRNA binding, are located at the gate of the interface region between the two domains. The molecular architecture suggests how this important protein has evolved from the ancient nucleic acid-binding proteins to create a 23S rRNA-binding domain in the very remote past.  (+info)

Crystal structure of a heparin- and integrin-binding segment of human fibronectin. (6/2878)

The crystal structure of human fibronectin (FN) type III repeats 12-14 reveals the primary heparin-binding site, a clump of positively charged residues in FN13, and a putative minor site approximately 60 A away in FN14. The IDAPS motif implicated in integrin alpha4beta1 binding is at the FN13-14 junction, rendering the critical Asp184 inaccessible to integrin. Asp184 clamps the BC loop of FN14, whose sequence (PRARI) is reminiscent of the synergy sequence (PHSRN) of FN9. Mutagenesis studies prompted by this observation reveal that both arginines of the PRARI sequence are important for alpha4beta1 binding to FN12-14. The PRARI motif may represent a new class of integrin-binding sites. The spatial organization of the binding sites suggests that heparin and integrin may bind in concert.  (+info)

A trans-acting peptide activates the yeast a1 repressor by raising its DNA-binding affinity. (7/2878)

The cooperative binding of gene regulatory proteins to DNA is a common feature of transcriptional control in both prokaryotes and eukaryotes. It is generally viewed as a simple energy coupling, through protein-protein interactions, of two or more DNA-binding proteins. In this paper, we show that the simple view does not account for the cooperative DNA binding of a1 and alpha2, two homeodomain proteins from budding yeast. Rather, we show through the use of chimeric proteins and synthetic peptides that, upon heterodimerization, alpha2 instructs a1 to bind DNA. This change is induced by contact with a peptide contributed by alpha2, and this contact converts a1 from a weak to a strong DNA-binding protein. This explains, in part, how high DNA-binding specificity is achieved only when the two gene regulatory proteins conjoin. We also provide evidence that features of the a1-alpha2 interaction can serve as a model for other examples of protein-protein interactions, including that between the herpes virus transcriptional activator VP16 and the mammalian homeodomain-containing protein Oct-l.  (+info)

Golgi structure in three dimensions: functional insights from the normal rat kidney cell. (8/2878)

Three-dimensional reconstructions of portions of the Golgi complex from cryofixed, freeze-substituted normal rat kidney cells have been made by dual-axis, high-voltage EM tomography at approximately 7-nm resolution. The reconstruction shown here ( approximately 1 x 1 x 4 microm3) contains two stacks of seven cisternae separated by a noncompact region across which bridges connect some cisternae at equivalent levels, but none at nonequivalent levels. The rest of the noncompact region is filled with both vesicles and polymorphic membranous elements. All cisternae are fenestrated and display coated buds. They all have about the same surface area, but they differ in volume by as much as 50%. The trans-most cisterna produces exclusively clathrin-coated buds, whereas the others display only nonclathrin coated buds. This finding challenges traditional views of where sorting occurs within the Golgi complex. Tubules with budding profiles extend from the margins of both cis and trans cisternae. They pass beyond neighboring cisternae, suggesting that these tubules contribute to traffic to and/or from the Golgi. Vesicle-filled "wells" open to both the cis and lateral sides of the stacks. The stacks of cisternae are positioned between two types of ER, cis and trans. The cis ER lies adjacent to the ER-Golgi intermediate compartment, which consists of discrete polymorphic membranous elements layered in front of the cis-most Golgi cisterna. The extensive trans ER forms close contacts with the two trans-most cisternae; this apposition may permit direct transfer of lipids between ER and Golgi membranes. Within 0.2 microm of the cisternae studied, there are 394 vesicles (8 clathrin coated, 190 nonclathrin coated, and 196 noncoated), indicating considerable vesicular traffic in this Golgi region. Our data place structural constraints on models of trafficking to, through, and from the Golgi complex.  (+info)

One of the first uses of vector graphic displays was the US SAGE air defense system. Vector graphics systems were retired from U.S. en route air traffic control in 1999, and are likely still in use in military and specialised systems. Vector graphics were also used on the TX-2 at the MIT Lincoln Laboratory by computer graphics pioneer Ivan Sutherland to run his program Sketchpad in 1963.. Subsequent bitmaps graphics systems, most of which iterated through dynamically modifiable stored lists of drawing instructions, include the IBM 2250, Imlac PDS-1, and DEC GT40. There was a home gaming system that used vector graphics called Vectrex as well as various arcade games like Asteroids, Space Wars and many cinematronics titles such as Rip-Off, and Tail Gunner using vector monitors. Storage scope displays, such as the Tektronix 4014, could display vector images but not modify them without first erasing the display..

Todays computer games have thousands of agents moving at the same time in areas inhabited by a large number of obstacles. In such an environment it is important to be able to calculate multiple shortest paths concurrently in an efficient manner. The highly parallel nature of the graphics processor suits this scenario perfectly. We have implemented a graphics processor based version of the A* path finding algorithm together with three algorithmic improvements that allow it to work faster and on bigger maps. The first makes use of pre-calculated paths for commonly used paths. The second use multiple threads that work concurrently on the same path. The third improvement makes use of a scheme that hierarchically breaks down large search spaces. In the latter the algorithm first calculates the path on a high level abstraction of the map, lowering the amount of nodes that needs to be visited. This algorithmic technique makes it possible to calculate more paths concurrently on large map settings ...

In a computer graphics system, an address generator processes physical and virtual addresses using a common command set. The address generator formulates addresses as a function of distance from the origin of the desired destination area in a destination memory to the requested position in the destination area. A plurality of context drawing commands is used to define a desired context in which drawing graphics commands operate. Different parts of the context are changeable/redefinable independently of the other parts. Graphics commands have a format of multiple fields having corresponding parameters arranged in order of common use of the parameter such that fields of less commonly used parameters are at an omittable end of the format. Raster drawing commands are delimited by a beginning and end indicator to form a drawing unit. For clip list processing, a drawing unit is stored as a single occurrence in the system command buffer.

HutDesign and GWB GWB is a procedure library for constructing and manipulating boundary models of solid objects. It currently supports faceted representations of solids having planar, quadric, or toroidal surfaces. For curved surfaces, exact surface data is available for accurate calculations. GWB is based on the pervasive use of Euler operators that act as the "assembly language" for higher-level algorithms such as solid primitives, sweeping, and Boolean set opera tions. Euler operators and their properties are discussed elsewhere (Mantylii 1978). Hence, the user interface design problem is split into three (deeply intertwined) problems, namely 36 Computer Model Figure I: Framework for Man-Machine Interaction (1) designing the computer model; (2) designing an interaction language that supports the users conceptual model of the task; and (3) designing the feedback to be provided to the user that allows him/her to interpret the state of the task in terms of his/hers conceptual model. In turn, ...

There is currently no algorithm that can efficiently render the rough appearance of real specular surfaces," Ramamoorthi said. "This is highly unusual in modern computer graphics, where almost any other scene can be rendered given enough computing power.". The researchers solution was to break down each pixel of an uneven, intricate surface into pieces covered by thousands of light-reflecting points smaller than a pixel, called microfacets. The team then computed the vector that is perpendicular to the surface of the materials for each microfacet, called the points normal. The normal is key to figuring out how light reflects off a surface.. For any specific computer-generated scene, the microfacets on a surface reflect light back to the computers virtual camera only if its normal is located exactly halfway between the ray from the light source and the light ray that bounces back from the surface. Computer scientists calculated the normals distribution within each patch of microfacets. Then ...

Muscles provide physiological functions to drive body movement and anatomically characterize body shape, making them a crucial component of modeling animated human figures. Substantial efforts have been expended on developing computational models of muscles for the purpose of increasing realism and accuracy in a broad range of applications, including computer graphics and biomechanics. We survey various approaches that have been employed to model and simulate muscles both morphologically and functionally.
Ever since humans constructed the first, crude dwellings, architecture has fluctuated between the disciplines of art and science, form and function. It has this in common with computer graphics technology, which also attracts practitioners from both artistic and scientific camps.
Toggle inverts the selection set (those items previously selected become unselected, those previously unselected become selected). Visibility: Excluding and Restoring A key capability in visual analysis is the ability to focus in on particular regions of interest. There are two aspects of the visibility capability: excluding and restoring data. The exclude button eliminates the unselected data items from the display so that only the selected set is visible. The restore button brings them back, making them visible again. Working together, selecting and excluding are extremely powerful. Starting with a large PivotTable users can quickly and easily identify unusual patterns and interactively select them. Using the exclude button, users can easily drill-in and focus on the interesting regions. The Totals Table (lower left corner) provides immediate feedback on what is selected and excluded. This helps users navigate without getting lost. If the PivotTable data came from a SQL Server 7 OLAP cube, ...

Computer graphics and computer vision were traditionally two distinct research fields focusing on opposite topics. Lately, they have been increasingly borrowing ideas and tools from each other. In this thesis, we investigate two problems in computer vision and graphics that rely on the same tool, namely energy optimization with graph cuts. In the area of computer graphics, we address the problem of generating artificial classic mosaics, still and animated. The main purpose of artificial mosaics is to help a user to create digital art. First we reformulate our previous static mosaic work in a more principled global optimization framework. Then, relying on our still mosaic algorithm, we develop a method for producing animated mosaics directly from real video sequences, which is the first such method, we believe. Our mosaic animation style is uniquely expressive. Our method estimates the motion of the pixels in the video, renders the frames with mosaic effect based on both the colour and motion information

Libre Graphics magazine spent five years showing off excellent work done with Free/Libre and Open Source graphics software. Our aim when we started was to challenge the idea that F/LOSS tools werent up to the job of doing professional graphic design work, especially in print. We published eight issues of a beautifully-printed, tactile, keepable paper magazine. We showed off the work of individuals and small studios doing exciting work with F/LOSS tools.. In the two years since we stopped making Libre Graphics magazine, a lot of exciting things have happened in the world of F/LOSS design. But one of the problems that keeps hanging on is the perception of F/LOSS graphics tools as somehow something less-than or other-than the "industry standard" set of tools that graphic designers are meant to use. This presentation looks at problems of F/LOSS adoption, especially for graphic design. It asks the question "What kinds of ecosystems do we need to have to successfully do Libre Graphics (including ...

By Lim Yeh Ern WHEN the first TeraFlop computer was introduced in 1996, it used 10,000 Intel Pentium Pro processors, each running at 200 megahertz (MHz), and consumed 500 kilowatts of power with an additional 500KW just to keep it cool. Now, the same TeraFlop computing is available on a single graphics processing unit, consumes only 110W of power and priced as low as US$199 (RM655) - in the form of the ATI Radeon HD4850. Based on the second-generation 55-nanometre chip process, the new TeraScale graphics engine combines 800 stream processors and almost one billion transistors, redefining high-definition gaming with seamless frame rates and high-resolution graphics with enhanced anti- aliasing and anisotropic filtering. All these create realistic- looking graphics in the latest DirectX 10 games. The HD4850 series employs GDDR3 memory with a core and memory clock of 625MHz and 993MHz respectively in a single-slot configuration, delivering two-gigabit-per-second memory bandwidth, while the ...

Data gathered from processes, or process data, contains many different aspects that a visualization system should also convey. Aspects such as, temporal coherence, spatial connectivity, streaming data, and the need for in-situ visualizations, which all come with their independent challenges. Additionally, as sensors get more affordable, and the benefits of measurements get clearer we are faced with a deluge of data, of which sizes are rapidly growing. With all the aspects that should be supported and the vast increase in the amount of data, the traditional techniques of dashboards showing the recent data becomes insufficient for practical use. In this thesis we investigate how to extend the traditional process visualization techniques by bringing the streaming process data into an interactive visual analysis setting. The augmentation of process visualization with interactivity enables the users to go beyond the mere observation, pose questions about observed phenomena and delve into the data to ...

Fremont, California, October 17, 2008 - S3 Graphics, a leading provider of graphics and HD Multimedia technologies, today announced the availability of S3FotoPro, a GPGPU application using the latest programmable architecture powered by the Chrome 400 Series GPUs. Utilizing an array of S3 stream processors, the GPUs can accelerate parallel data workloads and perform work on thousands of concurrent threads to achieve Gigaflops (GFLOPS) of high-throughput computations.. S3FotoPro is an example of a computationally expensive process for image quality improvements that is best achieved on a GPU instead of a CPU due to the S3 stream processor architecture. The algorithm complexity and high calculation requirements required by S3FotoPro enables the parallel workload speedup to be magnitudes (,100x) of times faster than the latest CPUs in the market today. In addition, the GFLOPS-per-Watt and GFLOPS-per-Dollar favor the GPU computational efficiency over standard CPU calculations.. "S3 Graphics ...
VA Linux Systems, Nvidia and SGI are to bring workstation-class graphics to Linux through the joint development of an OpenGL 1.2-based 2D and 3D graphics acceleration sub-system. Long-time collaborators Nvidia and SGI will provide Nvidias GeForce 256 3D graphics chip -- presumably in its pro-oriented Quadro form -- and the first official version of OpenGL 1.2 on Linux. OpenGL, while a de facto standard 3D rendering technology, isnt open source, and so has only made an appearance on Linux in the form of technologies such as Mesa, which essentially provide an OpenGL-style API. And they work very well -- the only snag is that, not being official ports of the SGI technology, they cant claim to be 100 per cent OpenGL compatible, primarily because they cant be put through SGIs compliance testing procedure. To be able to claim at last that it has a fully compatible implementation of OpenGL is a major step forward for Linux as a graphics workstation platform. And we can probably look forward to ...

Thats true even for machines with NVIDIA ION graphics. Because Adobe Flash doesnt currently take advantage of the GPU. Instead it relies on the CPU, and the Intel Atom processor just isnt up to these tasks.

In project postmortems I often hear "communication" as one of the major problems plaguing game development. For years I took this at face value and just thought, "sure, so we should talk more!". At the same time we continually complain about meetings that bog down our productivity. Is communication really a quantity issue? Maybe we should be investing in quality of communication? And taken further, perhaps, there are situations where poor communication is just a symptom of another larger roadblock?. That roadblock, my friends, is developers with divergent priorities.. In game development, I often see (graphics/systems) programmers view themselves as somehow fundamentally different than artists. Either they believe they exist to service requests from artists or alternatively they see themselves as the driving force behind development, and expect artists to fluidly adapt to their systems. Sometimes both of these flawed paradigms exist within the same project! The issue here is that the two groups ...

Boa Constructor has some code in their UML view that I contributed to do this using topological sorts.

Basically, you do the topo-sort, then lay out each generation above/below next/previous generations. For really nice-looking graphs, youd want to do some post-processing to make children show up underneath parents as much as possible (i.e. minimise number of crossing arcs in the graph), and maybe do some work with spacing so that each generation takes up approx. the same amount of space.

I think that this direction is a good one for laptops, to have both incredible battery life and enough power to get stuff done. Especially with both Intel and AMD working on SoCs that integrate the graphics onto the processor, I really hope they continue to work on this sort of hybrid graphics; it is probably more important for Intel chips since they have repeatedly shown that they could care less about graphics performance. All Intel would have to do is have enough GPU for Windows and browsing the internet, then someone who can actually make a decent GPU can add an a discrete chip that you can switch to when needed ...

An essential form of communication between the director and the animators early in the animation pipeline is rough cut at the motion (a blocked-in animation). This version of the characters performance allows the director and animators to discuss how the character will play his/her role in each scene. However, blocked-in animation is also quite time consuming to construct, with short scenes requiring many hours of preparation between presentations. In this paper, we present a puppeteering interface for creating blocked-in motion for characters and various simulation effects more quickly than is possible in a keyframing interface. The animator manipulates one of a set of tracked objects in a motion capture system to control a few degrees of freedom of the character on each take. We explore the design space for the 3D puppeteering interface with a set of seven professional animators using a "think-aloud" protocol. We present a number of animations that they created and compare the time required ...

We live in an age in which we are continuously confronted with all kinds of information, most of it coming to us in visual form. If we want to make sense of all this information, it is crucial that it is presented in a easily digestible way. While a given piece of abstract information can be visualized in virtually infinitely many different ways, not all of these are equally effective. An important question, therefore, is whether we can find objective criteria for effective visualization of information. This requires an interdisciplinary approach, because information visualization is a research branch of computing science, but how to do this effectively is a question related to vision and perceptual science. The emphasis in vision research has always been on central or foveal vision, with the result that we know relatively little about peripheral vision. However, knowledge about how we perceive objects in the periphery of our visual field is not only essential for coming to a full understanding ...
Two types of viewports are available: viewport widgets, and canvas viewport items. While canvas viewport items are generally slower in terms of rendering speed (due to their use of off-screen pixmaps), they give the user the ability to super-impose text and other canvas elements on top of rendered images, and offer faster screen refreshes of static scenes. On the other hand, viewport widgets draw directly into OpenGL windows and will therefore render much faster on systems with hardware OpenGL acceleration. ...

For computer visual fanatics, the mission statement with regards to photo realistic rendering involves the creation of a image that is very identical to a pic. This line of career involves learning the graphic program, simulating conventional media, correspondence despite low bandwidth, producing image abstracts, plus providing for the improvement of consumer interaction.. With computer images, the facts of a image are controlled. This really is oftentimes combined with all the thus called stylization in purchase to enhance a more perplexed ...

Nowadays, cluster analysis of biological networks has become one of the most important approaches to identifying functional modules as well as predicting protein complexes and network biomarkers. Furthermore, the visualization of clustering results is crucial to display the structure of biological networks. Here we present CytoCluster, a cytoscape plugin integrating six clustering algorithms, HC-PIN (Hierarchical Clustering algorithm in Protein Interaction Networks), OH-PIN (identifying Overlapping and Hierarchical modules in Protein Interaction Networks), IPCA (Identifying Protein Complex Algorithm), ClusterONE (Clustering with Overlapping Neighborhood Expansion), DCU (Detecting Complexes based on Uncertain graph model), IPC-MCE (Identifying Protein Complexes based on Maximal Complex Extension), and BinGO (the Biological networks Gene Ontology) function. Users can select different clustering algorithms according to their requirements. The main function of these six clustering algorithms is to detect
