Refiner tackle

Similarly, we have described how information related to protein-splicing variants, amino acid peptide variants (polymorphisms), and PTMs is being introduced in data analysis pipelines in order to increase the rate of identifiable peptides. The introduction of genomics and transcriptomics information, often neglected in routine proteomics analyses, will enable the characterization of myriad splicing variants and amino acid polymorphisms, as well as the development of robust proteomics analysis pipelines, which will contribute to elucidate their role in health and disease states. These tools will make it possible to uncover a new layer of the proteome complexity and to expand the information available from cellular systems and the potential implication of these protein variants in different physiological processes. Finally, several bioinformatics tools that perform unbiased PTM analysis have also been reviewed. The tools that are currently being developed and refined tackle...

Parallel refinement of multiple potential solutions is the method adopted by evolutionary algorithms. In this chapter, we discover why, when tackling optimization problems, it can be more productive to spread our efforts across a group of solutions rather than to concentrate on one. 

It also seems likely that some mental disorders (perhaps major depressive disorder) in their present form will fail to show evidence of taxonicity, but definitional refinement would help elucidate underlying taxa (e.g., melancholia). Thus, taxometrics may be able to serve as an impetus and a guide for revising the diagnostic system. Of course, taxometric methods alone are not sufficient to tackle this task and should be used in conjunction with dimensional methods, such as exploratory factor analysis. Dimensions provide the building blocks for construction of taxa, and research on the structure of psychopathology should integrate dimensional and taxometric methods. 

Testing of object and component designs can be more difficult than in traditional systems because of the added complication of polymorphism, inheritance, and arbitrary overriding of behaviors. The essential idea of testing is to verify that an implementation meets its specification—the same goal as that of refinement except that testing tackles the problem by monitoring runtime behaviors under a systematically derived set of test cases. This chapter outlines a systematic test approach based on refinement. 

Results of similar accuracy as relativistic TFDW are found with a simple procedure based on near-nuclear correction which leave space for further improvements. For the reasons mentioned at the end of previous section the direct way to improve the present approach seems to be the refinement of the near nuclear corrections, a problem that we have just tackled with success in the non-relativistic framework [31,32]. The aim was to describe the near-nuclear region accurately by means of using the quantum mechanical exact asymptotic expression up to of the different ns eigenstates of Schodinger equation with a fit of the semiclassical potential at short distancies to the exact asymptotic behaviour (with four terms) of the potential near the nucleus. The result is that the density below Tq becomes very close to Hartree-Fock values and the improvement of the energy values is large (as an example, the energy of Cs+ is improved from the Ashby-Holzman result of-189.5 keV up to -205.6, very close to the HF value of -204.6 keV). This result makes us expect that a similar procedure in the relativistic framework may provide results comparable to Dirac-Fock ones. 

A fundamental property of the Fourier transform is that of superposition. The usefulness of the Fourier method lies in the fact that one can separate a function into additive components, treat each one separately, and then build up the full result by summing the individual results. It is a beautiful and explicit example of the stepwise refinement of complex problems. In stepwise refinement, one successfully tackles the most difficult tasks and solves problems far beyond the mind s momentary grasp by dividing the problem into its ultimately simple pieces. The full solution is then obtained by reassembling the solved pieces. 

The aim of this chapter is to present a review of the high pressure optical studies on rare-earth ions in non-metallic compounds. Other methods, as for example neutron scattering, magnetic resonance techniques or MoBbauer spectroscopy will not be considered here, unless they provide additional valuable information to the optical studies. It will be demonstrated that the problem of host lattice structural dependence of 4f/v states can be effectively tackled by high pressure techniques and hopefully the interest for further, more refined high pressure studies of this problem can be stimulated. 

The evaluation of kinetic properties of NRPS systems is a problem of generally underestimated complexity. The basic path was established in 1971, defining activation, thiolation, and peptidyl transfers as basic reactions. The further refinement from structural data to establish the multiple carrier model, and now to tackle domain interactions, has added some precision to the questions asked. However, we have not yet arrived at a complete kinetic description of even the simple tripeptide synthetase. The ACV synthetase operates with four different substrates at six binding sites, releasing 3 moles of AMP and 3 moles of MgPPi for each ACV formed at optimal conditions [51], A sequence of 10 reactions has been... 

All of the structures tackled have been refined by least squares methods and, with few exceptions, by full-matrix least squares methods. The total computing investment over the past three years amounts to approximately 300 hours of central-processor time on a CDC-6400. When the necessary calculations have exceeded the capacity of the CDC-6400 (about 250 variables), we have turned to a remote hookup with the CDC-7600 at Lawrence Berkeley Laboratory.
