Future Development dynamics

The following sections cover the design goals, decisions, and outcomes of the first two major versions of NAMD and present directions for future development. It is assumed that the reader has been exposed to the basics of molecular dynamics [2, 3, 4] and parallel computing [5]. Additional information on NAMD is available electronically [6]. 

The examples discussed in this section provide encouraging leads for the future development of DCLs. Since a large number of biologically relevant substrates (and receptors) involve hydrogen bonding, it is certain that more templates using such interactions to amplify the formation of specific compounds from a dynamic library, will be developed in the future. 

Besides the analytical techniques, the theoretical description of polymer brushes allows a deeper understanding of the complex dynamic behavior of polymers on surfaces and is useful for future developments. Here, Roland Netz gives - also for the non-expert - a very helpful theoretical background on the theoretical approaches for the description of neutral and charged polymer brushes. 

Recent developments in instrument design have led to lower limits of detection, while new ion activation techniques and improved understanding of gas-phase ion chemistry have enhanced the capabilities of tandem mass spectrometry for peptide and protein structure elucidation. Future developments must address the understanding of protein-protein interactions and the characterization of the dynamic proteome (Chalmers and Gaskell 2000). 

LRT dynamics of POPs can be predicted and evaluated by environmental multimedia modeling (MMM). The models with different spatial scale such as POPsME, EDCSeoul, and KoEFT-PBTs have been developed to predict the fate and transport of classical POPs or VOCs in multi-media environments (Lee et al., 2004 NIER, 2001, 2002, 2003 Lee, 2005). These models are considered to serve as a basis for the future development of LRT models of the north-east Asian region. 

In this report, chemical imaging is defined as the spatial and temporal characterization of the molecular composition, structure, and dynamics of any given sample—with the ultimate goal being able to both understand and control complex chemical processes. As illustrated by the case studies in Chapter 2, this ability to image or visualize chemical events in space and time is essential to the future development of many fields of science. 

In the following we consider the nature of LIFS in more detail. The theoretical foundations of laser excitation and fluorescence are outlined and such issues as detectability and dynamic range are discussed. Finally the status of LIFS is summarized and a prognosis for future development given. 

Both population and coherence experiments provide information on the dynamics and interactions of condensed matter systems. In addition, time domain vibrational experiments can extract spectroscopic information that is hidden in a conventional measurement of the infrared or Raman spectra. This book will provide the reader with a picture of the state of the art and a perspective on future developments in the field of ultrafast infrared and Raman spectroscopy. 

In the Section XI, we summarize the major points of this chapter. We will also propose future development of our strategy with application to systems with many degrees of freedom— for example, the dynamics of protein folding. We suggest that coarse graining of the phase-space strucmre may need to be incorporated to tackle such a problem. 

In the Car and Parrinello (1985) scheme, ion dynamics is combined with a fictitious classical electron dynamics, with nuclei assigned real masses and the electron wave functions arbitrary fictitious masses. One starts the molecular-dynamics simulation at high temperature and cools progressively to zero temperature to find the ground state of both electrons and ions simultaneously. Although this approach at first seems strange and unphysical, it has yielded excellent results for amorphous Si (Car and Parrinello, 1988) and recently for SiOj (Allan and Teter, 1987) and S clusters (Hohl et al., 1988) and will probably play an important role in the future development of the field. 

However, these efforts need to be combined with new research works in the process dynamics and in the study of advanced control systems applied to integrated membrane systems. These multidisciplinary smdies will offer interesting opportunities for the future development of membrane engineering. 

Phonon spectroscopy has been found to be a powerful method to Investigate the reaction dynamics In solid state. Also, non-llnear laser spectroscopic study has been used to probe the dynamics of photochemical reactions. Future directions are clearly a more quantitative and theoretical formulation of the Importance of energy state dynamics In determining reactivity In the condensed phase. Non-llnear spectroscopy as well as time-resolved X-ray crystallography using synchrotron radiation can be expected to provide valuable approaches for future development of a dynamic model of solid state polymerization. 

Spacetime is a dynamic entity, and as such it would have quantum properties (Rovelli, 2000). Both current and future developments in theoretical physics have to investigate the concept of discrete excitations of space itself. Thus, process thought, as a philosophical system, cannot be ruled out at present, because of an unfinished debate in theoretical physics. 

The main body of this volume presents results that have been obtained in dynamical studies of proteins in vacuum, in solution, and in crystals. Because of the intense activity in this area, a selection has been made to provide a representative and coherent view of our present knowledge. Where possible, comparisons with experiment and the functional correlates of the motions are stressed. A description is given of specific experimental areas that are of particular importance for the analysis of dynamics or where the simulation results are providing information essential for the interpretation of the experimental data. We conclude with an outlook for future developments and applications in this exciting field. 

Chapter 8—Molecular Interactions Learning from Protein Complexes The spectrum of interactions is critical to comprehending the dynamics of a living system, and understanding it can help to develop methodology for future studies in other systems. Rojas, de Juan, and Valencia review the current state of experimental and computational methods for the study of protein interactions, including prospects for future developments. 

With the current growing appreciation of cellular processes as molecular chemical machines, it is clear that more ample understanding, beyond lesion processing by polymerases, is needed. In the cell, there is a dynamic interplay between replication, transcription, and various repair mechanisms [105-108]. How these various processes are called into play in the face of DNA lesions is currently the focus of research in areas that span structural, molecular, cellular, and systems biology, with computational approaches playing increasingly vital roles [109]. Recent advances in these areas promise exciting future developments.
