Threading

The selection of a template typically follows BLAST-type searches and sequence alignments. The template selection is based on the similarity of sequences but neglects the possibility that templates with a similar structure may have differing protein functions. Threading provides a way to account for the possibility that functionally different proteins share similar structures. Instead of matching the target sequence to all possible sequences (with or [Pg.73]

We proved this conjecture for f=3,5,7 and came up with rather tight bounds for k 7. Surprisingly, the proofs for all these three cases use different ideas. [Pg.8]

2-Threading provides an optimal threading for OTP with the threshold 5. [Pg.8]

We prove that the overall load of every threading with threshold 5 is at most 2/3 n. Since the number of 5-close vertices in 2-threading is 215 n asymptotically it proves that 2-threading is optimal for this threshold. [Pg.10]

At the other extreme are materials which flow like liquids but show a tendency to recoil when the stress is removed. This has been called flow-elasticity or elastico-viscosity . Such liquids (e.g. molten Nylon) can be spun to form threads. [Pg.421]

The Research-Production Company (RPC) Zond (city of Ivano-Frankivsk) now is a well-known centre for development, fabrication and introduction of the technologies and methods of NOT of oil and gas equipment and tools Its experts developed and introduced the technologies and equipment which enables control of the drill pipes, especially their threaded joints, oil and gas equipment, sort out the pipes into groups by the strength and yield point of the pipes material, etc. [Pg.971]

Carbon disulphide is an excellent solvent for fats, oils, rubber, sulphur, bromine and iodine, and is used industrially as a solvent for extraction. It is also used in the production of viscose silk, when added to wood cellulose impregnated with sodium hydroxide solution, a viscous solution of cellulose xanthate is formed, and this can be extruded through a fine nozzle into acid, which decomposes the xanthate to give a glossy thread of cellulose. [Pg.202]

Fig. 6. Multiple threads in NAMD 2 allow the integration algorithm to be expressed sequentially as a single function. This function, shown illegibly at left, runs in sequencer threads associated with home patches. A similar function running in a controller thread on the master node communicates with the sequencers to deal with output and global calculations. Compute objects execute in the larger stack space of each node s main thread. Fig. 6. Multiple threads in NAMD 2 allow the integration algorithm to be expressed sequentially as a single function.

Compute objects execute in the larger stack space of each node s main thread.
As noted above, one of the goals of NAMD 2 is to take advantage of clusters of symmetric multiprocessor workstations and other non-uniform memory access platforms. This can be achieved in the current design by allowing multiple compute objects to run concurrently on different processors via kernel-level threads. Because compute objects interact in a controlled manner with patches, access controls need only be applied to a small number of structures such as force and energy accumulators. A shared memory environment will therefore contribute almost no parallel overhead and generate communication equal to that of a single-processor node. [Pg.480]

The fifth and final chapter, on Parallel Force Field Evaluation, takes account of the fact that the bulk of CPU time spent in MD simulations is required for evaluation of the force field. In the first paper, BOARD and his coworkers present a comparison of the performance of various parallel implementations of Ewald and multipole summations together with recommendations for their application. The second paper, by Phillips et AL., addresses the special problems associated with the design of parallel MD programs. Conflicting issues that shape the design of such codes are identified and the use of features such as multiple threads and message-driven execution is described. The final paper, by Okunbor Murty, compares three force decomposition techniques (the checkerboard partitioning method. [Pg.499]

Ithough knowledge-based potentials are most popular, it is also possible to use other types potential function. Some of these are more firmly rooted in the fundamental physics of iteratomic interactions whereas others do not necessarily have any physical interpretation all but are able to discriminate the correct fold from decoy structures. These decoy ructures are generated so as to satisfy the basic principles of protein structure such as a ose-packed, hydrophobic core [Park and Levitt 1996]. The fold library is also clearly nportant in threading. For practical purposes the library should obviously not be too irge, but it should be as representative of the different protein folds as possible. To erive a fold database one would typically first use a relatively fast sequence comparison lethod in conjunction with cluster analysis to identify families of homologues, which are ssumed to have the same fold. A sequence identity threshold of about 30% is commonly... [Pg.562]

For ethyl alcohol, two volumes of dicycZohexyl are mixed with one volume of the alcohol, a thermometer is introduced, and the mixture heated until it becomes clear. The solution is then slowly cooled, with constant stirring, and the temperature is determined at which the opalescent solution suddenly becomes turbid so that the immersed portion of the mercury thread of the thermometer is no longer clearly visible. This is the C.S.T. The water content may then be evaluated by reference to the following table. [Pg.21]

Many simulations attempt to determine what motion of the polymer is possible. This can be done by modeling displacements of sections of the chain, Monte Carlo simulations, or reptation (a snakelike motion of the polymer chain as it threads past other chains). These motion studies ultimately attempt to determine a correlation between the molecular motion possible and the macroscopic flexibility, hardness, and so on. [Pg.311]

As the second educt (B), the plasmid ONA with complementary sticky ends is prepared separately. In the first step the isolated plasmid DNA is cut open by a special type of enzyme called restriction endonuclease. It scans along the thread of DNA and recognizes short nucleotide sequences, e.g., CTGCAG, which ate cleaved at a specific site, e.g., between A and G. Some 50 of such enzymes are known and many are commercially available. The ends are then again extended witfa he aid of a terminal transferase by a short sequence of identical nucleotides complementary to the sticky ends of educt (A). [Pg.243]

Nucleic acids are acidic substances present m the nuclei of cells and were known long before anyone suspected they were the primary substances involved m the storage transmission and processing of genetic information There are two kinds of nucleic acids ribonucleic acid (RNA) and deoxyribonucleic acid (DNA) Both are complicated biopolymers based on three structural units a carbohydrate a phosphate ester linkage between carbohydrates and a heterocyclic aromatic compound The heterocyclic aro matic compounds are referred to as purine and pyrimidine bases We 11 begin with them and follow the structural thread... [Pg.1155]
