  abstract = {While the prediction of hydrodynamic properties of rigid particles
    is nowadays feasible using simple and efficient computer programs,
    the calculation of such properties and, in general, the dynamic
    behavior of flexible macromolecules has not reached a similar situation.
    Although the theories are available, usually the computational work
    is done using solutions specific for each problem. We intend to
    develop computer programs that would greatly facilitate the task
    of predicting solution behavior of flexible macromolecules. In this
    paper, we first present an overview of the two approaches that are
    most practical: the Monte Carlo rigid-body treatment, and the Brownian
    dynamics simulation technique. The Monte Carlo procedure is based
    on the calculation of properties for instantaneous conformations
    of the macromolecule that are regarded as if they were instantaneously
    rigid. We describe how a Monte Carlo program can be interfaced to
    the programs in the HYDRO suite for rigid particles, and provide
    an example of such calculation, for a hypothetical particle: a protein
    with two domains connected by a flexible linker. We also describe
    briefly the essentials of Brownian dynamics, and propose a general
    mechanical model that includes several kinds of intramolecular interactions,
    such as bending, internal rotation, excluded volume effects, etc.
    We provide an example of the application of this methodology to
    the dynamics of a semiflexible, wormlike DNA.},

  year = {2005},
  volume = {123},
  pages = {-},

  month = {Oct 8},
  abstract = {Time series analysis tools are employed on the principal modes obtained
    from the C-alpha trajectories from two independent molecular-dynamics
    simulations of alpha-amylase inhibitor (tendamistat). Fluctuations
    inside an energy minimum (intraminimum motions), transitions between
    minima (interminimum motions), and relaxations in different hierarchical
    energy levels are investigated and compared with those encountered
    in vacuum by using different sampling window sizes and intervals.
    The low-frequency low-indexed mode relationship, established in
    vacuum, is also encountered in water, which shows the reliability
    of the important dynamics information offered by principal components
    analysis in water. It has been shown that examining a short data
    collection period (100 ps) may result in a high population of overdamped
    modes, while some of the low-frequency oscillations (< 10 cm(-1))
    can be captured in water by using a longer data collection period
    (1200 ps). Simultaneous analysis of short and long sampling window
    sizes gives the following picture of the effect of water on protein
    dynamics. Water makes the protein lose its memory: future conformations
    are less dependent on previous conformations due to the lowering
    of energy barriers in hierarchical levels of the energy landscape.
    In short-time dynamics (< 10 ps), damping factors extracted from
    time series model parameters are lowered. For tendamistat, the friction
    coefficient in the Langevin equation is found to be around 40-60
    cm(-1) for the low-indexed modes, compatible with literature. The
    fact that water has increased the friction and that on the other
    hand has lubrication effect at first sight contradicts. However,
    this comes about because water enhances the transitions between
    minima and forces the protein to reduce its already inherent inability
    to maintain oscillations observed in vacuum. Some of the frequencies
    lower than 10 cm(-1) are found to be overdamped, while those higher
    than 20 cm(-1) are slightly increased. As for the long-time dynamics
    in water, it is found that random-walk motion is maintained for
    approximately 200 ps (about five times of that in vacuum) in the
    low-indexed modes, showing the lowering of energy barriers between
    the higher-level minima.},

    scattering from rodlike sturctures and from a model of a DNA fragment

    translational anisotropy is increased form zero to a large value.
    Simulated first cumulants as well as amplitudes and lifetimes of
    the dynamic form factor are compared with predictions of analytic
    theories and found to be in very good agreement with them. For DNA
    fragments 762 base pairs in length or longer, translational anisotropy
    does not contribute significantly to dynamic light scattering. In
    a comparison of rigid and flexible simulations on semistiff models
    of this fragment, it is shown directly that flexing contributes
    to the faster decay processes probed by light scattering and that
    the flexible model studies are in good agreement with experiment.},

  abstract = {Acetylcholine receptor channels (AChRs) are proteins that switch between
    stable #closed# and #open# conformations. In patch clamp recordings,
    diliganded AChR gating appears to be a simple, two-state reaction.
    However, mutagenesis studies indicate that during gating dozens
    of residues across the protein move asynchronously and are organized
    into rigid body gating domains (#blocks#). Moreover, there is an
    upper limit to the apparent channel opening rate constant. These
    observations suggest that the gating reaction has a broad, corrugated
    transition state region, with the maximum opening rate reflecting,
    in part, the mean first-passage time across this ensemble. Simulations
    reveal that a flat, isotropic energy profile for the transition
    state can account for many of the essential features of AChR gating.
    With this mechanism, concerted, local structural transitions that
    occur on the broad transition state ensemble give rise to fractional
    measures of reaction progress (Phi values) determined by rate-equilibrium
    free energy relationship analysis. The results suggest that the
    coarse-grained AChR gating conformational change propagates through
    the protein with dynamics that are governed by the Brownian motion
    of individual gating blocks.},

    units near the interface generally show a very small increase in
    segmental order, while segments deeper within the bilayer show a
    small decrease in segmental order. From the H-2 NMR results, the
    chain length for the perdeuterated palmitoyl chain in the absence
    of anesthetic was found to be 12.35 Angstrom. Upon the addition
    of halothane enflurane, or isoflurane, the acyl chain undergoes
    slight contractions of 0.11, 0.20, or 0.16 Angstrom, respectively,
    at 50 mol % anesthetic. A simple model was used to estimate the
    relative amounts of anesthetic located near the interface and deeper
    in the bilayer hydrocarbon region, and only a slight preference
    for an interfacial location was observed. Intermolecular H-1-H-1
    nuclear Overhauser effects (NOEs) were measured between phospholipid
    and halothane protons. These NOEs are consistent with the intramembrane
    location of the anesthetics suggested by the H-2 NMR data. In addition,
    the NOE data indicate that anesthetics prefer the interfacial and
    hydrocarbon regions of the membrane and are not found in high concentrations

    dynamics according to the Langevin equation that arose fortuitously
    upon analysis of the range of harmonic validity of our normal-mode
    scheme LIN. LN combines force linearization with force splitting
    techniques and disposes of LIN'S computationally intensive minimization
    (anharmonic correction) component. Unlike the competitive multiple-timestepping
    (MTS) schemes today-formulated to be symplectic and time-reversible-LN
    merges the slow and fast forces via extrapolation rather than impulses;
    the Langevin heat bath prevents systematic energy drifts. This combination
    succeeds in achieving more significant speedups than these MTS methods
    which are Limited by resonance artifacts to an outer timestep less
    than some integer multiple of half the period of the fastest motion
    (around 4-5 fs for biomolecules). We show that LN achieves very
    good agreement with small-timestep solutions of the Langevin equation
    in terms of thermodynamics (energy means and variances), geometry,
    and dynamics (spectral densities) for two proteins in vacuum and
    a large water system. Significantly, the frequency of updating the
    slow forces extends to 48 fs or more, resulting in speedup factors
    exceeding 10. The implementation of LN in any program that employs
    force-splitting computations is straightforward, with only partial
    second-derivative information required, as well as sparse Hessian/vector
    multiplication routines. The linearization part of LN could even
    be replaced by direct evaluation of the fast components. The application
    of LN to biomolecular dynamics is well suited for configurational
    sampling, thermodynamic, and structural questions. (C) 1998 American

    namely the anisotropies of the two arms and the angle between them.
    The behavior of the model has been investigated using Monte Carlo
    simulations for a wide range of these structural parameters. This
    allows us to establish the relationship between the V-shaped molecule
    and its ability to form a biaxial nematic phase. Of particular importance
    are the criteria of geometry and the relative anisotropy necessary
    for the system to exhibit a Landau point, at which the biaxial nematic
    is formed directly from the isotropic phase. The simulations have
    also been used to determine the orientational order parameters for
    a selection of molecular axes. These are especially important because
    they reveal the phase symmetry and are connected to the experimental
    determination of this. The simulation results show that, whereas
    some positions are extremely sensitive to the phase biaxiality,
    others are totally blind to this.},

  abstract = {Fluids of hard bent-core molecules have been studied using theory
    and computer simulation. The molecules are composed of two hard
    spherocylinders, with length-to-breadth ratio L/D, joined by their
    ends at an angle 180 degrees - gamma. For L/D = 2 and gamma = 0,10,20
    degrees, the simulations show isotropic, nematic, smectic, and solid
    phases. For L/D = 2 and gamma = 30 degrees, only isotropic, nematic,
    and solid phases are in evidence, which suggests that there is a
    nematic-smectic-solid triple point at an angle in the range 20 degrees
    < gamma < 30 degrees. In all of the orientationally ordered fluid
    phases the order is purely uniaxial. For gamma = 10 degrees and
    20 degrees, at the studied densities, the solid is also uniaxially
    ordered, whilst for gamma = 30 degrees the solid layers are biaxially
    ordered. For L/D = 2 and gamma = 60 degrees and 90 degrees we find
    no spontaneous orientational ordering. This is shown to be due to
    the interlocking of dimer pairs which precludes alignment. We find
    similar results for L/D = 9.5 and gamma = 72 degrees, where an isotropic-biaxial
    nematic transition is predicted by Onsager theory. Simulations in
    the biaxial nematic phase show it to be at least mechanically stable
    with respect to the isotropic phase, however. We have compared the
    quasi-exact simulation results in the isotropic phase with the predicted
    equations of state from three theories: the virial expansion containing
    the second and third virial coefficients; the Parsons-Lee equation
    of state; an application of Wertheim's theory of associating fluids
    in the limit of infinite attractive association energy. For all
    of the molecule elongations and geometries we have simulated, the
    Wertheim theory proved to be the most accurate. Interestingly, the
    isotropic equation of state is virtually independent of the dimer
    bond angle-a feature that is also reflected in the lack of variation
    with angle of the calculated second and third virial coefficients.

    with the existing HYDRO software, the new program BROWNRIG (including
    a case-specific subprogram for the external agent) carries out a
    simulation that is analyzed later to extract the observable dynamic
    properties. We provide a variety of examples of utilization of this

    functions (CFs) of generalized coordinates is established, and the
    diffusion equation with memory (DEM) is deduced from the FPE in
    the high friction Limit. The DEM is invoked to perform illustrative
    calculations in two dimensions of the orientational CFs for once
    broken nonrigid rods immobilized on a surface. These calculations
    reveal that the CFs under certain conditions exhibit an oscillatory

    a new method to predict protein-protein complexes from the coordinates

    rigid-body, Monte Carlo search followed by simultaneous optimization
    of backbone displacement and side-chain conformations using Monte
    Carlo minimization. Up to 10(5) independent simulations are carried
    out, and the resulting #decoys# are ranked using an energy function
    dominated by van der Waals interactions, an implicit solvation model,
    and an orientation-dependent hydrogen bonding potential. Top-ranking
    decoys are clustered to select the final predictions. Small-perturbation
    studies reveal the formation of binding funnels in 42 of 54 cases
    using coordinates derived from the bound complexes and in 32 of
    54 cases using independently determined coordinates of one or both
    monomers. Experimental binding affinities correlate with the calculated
    score function and explain the predictive success or failure of
    many targets. Global searches using one or both unbound components
    predict at least 25% of the native residue-residue contacts in 28
    of the 32 cases where binding funnels exist. The results suggest
    that the method may soon be useful for generating models of biologically
    important complexes from the structures of the isolated components,

    consistent and accurate prediction of protein-protein interactions.

  abstract = {A new procedure for studying the folding and unfolding of proteins,
    with an application to bovine pancreatic trypsin inhibitor (BPTI),
    is reported. The unfolding and refolding of the native structure
    of the protein are characterized by the dimensions of the protein,
    expressed in terms of the three principal radii of the structure
    considered as an ellipsoid. A dynamic equation, describing the variations
    of the principal radii on the unfolding path, and a numerical procedure
    to solve this equation are proposed. Expanded and distorted conformations
    are refolded to the native structure by a dimensional-constraint
    energy minimization procedure. A unique and reproducible unfolding
    pathway for an intermediate of BPTI lacking the [30,51] disulfide
    bond is obtained. The resulting unfolded conformations are extended;
    they contain near-native local structure, but their longest principal
    radii are more than 2.5 times greater than that of the native structure.
    The most interesting finding is that the majority of expanded conformations,
    generated under various conditions, can be refolded closely to the
    native structure, as measured by the correct overall chain fold,
    by the rms deviations from the native structure of only 1.9-3.1
    angstrom, and by the energy differences of about 10 kcal/mol from
    the native structure. Introduction of the [30,51] disulfide bond
    at this stage, followed by minimization, improves the closeness
    of the refolded structures to the native structure, reducing the
    rms deviations to 0.9-2.0 angstrom. The unique refolding of these
    expanded structures over such a large conformational space implies
    that the folding is strongly dictated by the interactions in the
    amino acid sequence of BPTI. The simulations indicate that, under
    conditions that favor a compact structure as mimicked by the volume
    constraints in our algorithm; the expanded conformations have a
    strong tendency to move toward the native structure; therefore,
    they probably would be favorable folding intermediates. The results
    presented here support a general model for protein folding, i.e.,
    progressive formation of partially folded structural units, followed
    by collapse to the compact native structure. The general applicability
    of the procedure is also discussed.},

    paper, we try to understand the form and origin of the anharmonicities,
    with the principal aim of gaining a better understanding of the
    principal motion types, but also in order to develop more efficient
    numerical methods for simulating neutron scattering spectra of large
    proteins. First, we decompose a molecular dynamics (MD) trajectory
    of 1.5 ns for a C-phycocyanin dimer surrounded by a layer of water
    into three contributions that we expect to be independent: the global
    motion of the residues, the rigid-body motion of the sidechains
    relative to the backbone, and the internal deformations of the sidechains.
    We show that they are indeed almost independent by verifying the
    factorization of the incoherent intermediate scattering function.
    Then, we show that the global residue motions, which include all
    large-scale backbone motions, can be reproduced by a simple harmonic
    model which contains two contributions: a short-time vibrational
    term, described by a standard normal mode calculation in a local
    minimum, and a long-time diffusive term, described by Brownian motion
    in an effective harmonic potential. The potential and the friction
    constants were fitted to the MD data. The major anharmonic contribution
    to the incoherent intermediate scattering function comes from the
    rigid-body diffusion of the sidechains. This model can be used to
    calculate scattering functions for large proteins and for long-time
    scales very efficiently, and thus provides a useful complement to
    MD simulations, which are best suited for detailed studies on smaller
    systems or for shorter time scales. (C) 2000 Elsevier Science B.V.

    hydrophobic interface ot the membrane proteins, gramicidin and apocytochrome
    C, using two related fluorescence spectroscopic approaches. The
    first approach exploited the fact that the presence of water in
    the excited state solvent cage of a fluorophore increases the rate
    of decay. For 1,6-diphenyl-1,3,5-hexatriene (DPH) and 1-palmitoyl-2-[[2-[4-(6-phenyl-trans-1,3,5-hexatrienyl)
    phenyl]ethyl]carbonyl]-3-sn-PC (DPH-PC), where the fluorophores
    are located in the hydrophobic core of the lipid bilayer, the introduction
    of gramicidin reduced the fluorescence lifetime, indicative of an
    increased presence of water in the bilayer. Since a high protein:lipid
    ratio was used, the fluorophores were forced to be adjacent to the
    protein hydrophobic surface, hence the presence of water in this
    region could be inferred. Cholesterol is known to reduce the water
    content of lipid bilayers and this effect was maintained at the
    protein-lipid interface with both gramicidin and apocytochrome C,
    again suggesting hydration in this region. The second approach was
    to use the fluorescence enhancement induced by exchanging deuterium
    oxide (D2O) for H2O. Both the fluorescence intensities of trimethylammonium-DPH,
    located in the lipid head group region, and of the gramicidin intrinsic
    tryptophans were greater in a D2O buffer compared with H2O, showing
    that the fluorophores were exposed to water in the bilayer at the
    protein-lipid interface. In the presence of cholesterol the fluorescence
    intensity ratio of D2O to H2O decreased, indicating a removal of
    water by the cholesterol, in keeping with the lifetime data. Altered
    hydration at the protein-lipid interface could affect conformation,
    thereby offering a new route by which membrane protein functioning

  abstract = {In this paper we show the possibility of using very mild stochastic
    damping to stabilize long time step integrators for Newtonian molecular
    dynamics. More specifically, stable and accurate integrations are
    obtained for damping coefficients that are only a few percent of
    the natural decay rate of processes of interest, such as the velocity
    autocorrelation function. Two new multiple time stepping integrators,
    Langevin Molly (LM) and Brunger-Brooks-Karplus-Molly (BBK-M), are
    introduced in this paper. Both use the mollified impulse method
    for the Newtonian term. LM uses a discretization of the Langevin
    equation that is exact for the constant force, and BBK-M uses the
    popular Brunger-Brooks-Karplus integrator (BBK). These integrators,
    along with an extrapolative method called LN, are evaluated across
    a wide range of damping coefficient values. When large damping coefficients
    are used, as one would for the implicit modeling of solvent molecules,
    the method LN is superior, with LM closely following. However, with
    mild damping of 0.2 ps(-1), LM produces the best results, allowing
    long time steps of 14 fs in simulations containing explicitly modeled
    flexible water. With BBK-M and the same damping coefficient, time
    steps of 12 fs are possible for the same system. Similar results
    are obtained for a solvated protein-DNA simulation of estrogen receptor
    ER with estrogen response element ERE. A parallel version of BBK-M
    runs nearly three times faster than the Verlet-I/r-RESPA (reversible
    reference system propagator algorithm) when using the largest stable
    time step on each one, and it also parallelizes well. The computation
    of diffusion coefficients for flexible water and ER/ERE shows that
    when mild damping of up to 0.2 ps-1 is used the dynamics are not
    significantly distorted. (C) 2001 American Institute of Physics.},

    in a quaternion representation. The nonseparable form of the Hamiltonian
    in quaternions prevents the use of a standard leapfrog (Verlet)
    integrator, so nonsymplectic Runge-Kutta, multistep, or extrapolation
    methods are generally used, This is unfortunate since symplectic
    methods like Verlet exhibit superior energy conservation in long-time
    integrations. In this article, we describe an alternative method,
    which we call RSHAKE (for rotation-SHAKE), in which the entire rotation
    matrix is evolved (using the scheme of McLachlan and Scovel [J.
    Nonlin. Sci, 16 233 (1995)]) in tandem with the particle positions.
    We employ a fast approximate Newton solver to preserve the orthogonality
    of the rotation matrix. We test our method on a system of soft-sphere
    dipoles and compare with quaternion evolution using a 4th-order
    predictor-corrector integrator, Although the short-time error of
    the quaternion algorithm is smaller for fixed time step than that
    for RSHAKE, the quaternion scheme exhibits an energy drift which
    is not observed in simulations with RSHAKE, hence a fixed energy
    tolerance can be achieved by using a larger time step, The superiority
    of RSHAKE increases with system size. (C) 1997 American Institute

    the molecular origins of polar and chiral symmetry breaking. We
    present the phase diagram of hard spherocylinder dimers of length-diameter
    ratio of 5 as a function of pressure or density and dimer opening
    angle psi. With decreasing psi, a transition from a nonpolar to
    a polar smectic A phase is observed near psi=167degrees, and the
    nematic phase becomes thermodynamically unstable for psi<135degrees.
    Free energy calculations indicate that the antipolar smectic A (SmAP(A))
    phase is more stable than the polar smectic A phase (SmAP(F)). No
    chiral smectic or biaxial nematic phases were found.},

    obtained directly from the variational principle. In particular,
    we prove that a unique multisymplectic structure is obtained by
    taking the derivative of an action function, and use this structure
    to prove covariant generalizations of conservation of symplecticity
    and Noether's theorem. Natural discretization schemes for PDEs,
    which have these important preservation properties, then follow
    by choosing a discrete action functional. In the case of mechanics,
    we recover the variational symplectic integrators of Veselov type,
    while for PDEs we obtain covariant spacetime integrators which conserve
    the corresponding discrete multisymplectic form as well as the discrete
    momentum mappings corresponding to symmetries. We show that the
    usual notion of symplecticity along an infinite-dimensional space
    of fields can be naturally obtained by making a spacetime split.
    All of the aspects of our method are demonstrated with a nonlinear

    means of Monte Carlo simulations in the isobaric-isothermal ensemble

    an untilted smectic phase showing a global phase biaxiality and
    a spontaneous local polarization in the layers, i.e. a local polar

    DNA can potentially induce long-range structural deformations integral
    to mechanisms of biological significance in both prokaryotes and
    eukaryotes. In this paper, we introduce a dynamic computer model
    for investigating this phenomenon. Duplex DNA is represented as
    a chain of hydrodynamic beads interacting through potentials of
    linearly elastic stretching, bending, and twisting, as well as excluded
    volume. The chain, linear when relaxed, is looped to form two open
    but topologically constrained subdomains. This permits the dynamic
    introduction of torsional stress via a centrally applied torque.
    We simulate by Brownian dynamics the 100 mus response of a 477-base
    pair B-DNA template to the localized torque generated by the prokaryotic
    transcription ensemble. Following a sharp rise at early times, the
    distributed twist assumes a nearly constant value in both subdomains,
    and a succession of supercoiling deformations occurs as superhelical
    stress is increasingly partitioned to writhe. The magnitude of writhe
    surpasses that of twist before also leveling off when the structure
    reaches mechanical equilibrium with the torsional load. Superhelicity
    is simultaneously right handed in one subdomain and left handed
    in the other, as predicted by the #transcription-induced##twin-supercoiled-domain#

    5. It is shown how the free parameters of these methods can be used
    either to minimize the continuous truncation error coefficients
    or to maximize the stability region. As a representative for these
    methods the fifth-order method with minimized error coefficients
    is chosen, supplied with an error estimation method, and analysed
    by using the DETEST software. The results are compared with a similar
    implementation of the Dormand-Prince 5(4) pair with interpolant,

    magnetic moment is numerically solved (properly observing the customary
    interpretation of it as a Stratonovich stochastic differential equation),
    in order to study the dynamics of magnetic nanoparticles. The corresponding
    Langevin-dynamics approach allows for the study of the fluctuating
    trajectories of individual magnetic moments, where we have encountered
    remarkable phenomena in the overbarrier rotation process, such as
    crossing-back or multiple crossing of the potential barrier, rooted
    in the gyromagnetic nature of the system. Concerning averaged quantities,
    we study the linear dynamic response of the archetypal ensemble
    of noninteracting classical magnetic moments with axially symmetric
    magnetic anisotropy. The results are compared with different analytical
    expressions used to model the relaxation of nanoparticle ensembles,
    assessing their accuracy. It has been found that, among a number
    of heuristic expressions for the linear dynamic susceptibility,
    only the simple formula proposed by Shliomis and Stepanov matches
    the coarse features of the susceptibility reasonably. By comparing
    the numerical results with the asymptotic formula of Storonkin {Sov.

    curves but their dramatic influence on the phase shifts. Comparison

    Here, we apply protein docking simulations and analysis of the interaction
    energy landscapes to identify protein-protein interaction sites.
    The new protocol for global docking based on multi-start global
    energy optimization of an allatom model of the ligand, with detailed
    receptor potentials and atomic solvation parameters optimized in
    a training set of 24 complexes, explores the conformational space

    the rigid-body docking solutions generated by the simulations were
    subsequently used to project the docking energy landscapes onto
    the protein surfaces. We found that highly populated low-energy
    regions consistently corresponded to actual binding sites. The procedure
    was validated on a test set of 21 known protein-protein complexes
    not used in the training set. As much as 81% of the predicted high-propensity
    patch residues were located correctly in the native interfaces.
    This approach can guide the design of mutations on the surfaces

    the long time behavior of numerical integration methods. This is
    true in particular for the integration of Hamiltonian systems where
    backward error analysis can be used to show that a symplectic method
    will conserve energy over exponentially long periods of time. Such
    results are typically based on two aspects of backward error analysis:
    (i) It can be shown that the modified vector fields have some qualitative
    properties which they share with the given problem and (ii) an estimate
    is given for the difference between the best interpolating vector
    field and the numerical method. These aspects have been investigated
    recently, for example, by Benettin and Giorgilli in [J. Statist.
    Phys., 74 (1994), pp. 1117-1143], by Hairer in [Ann. Numer. Math.,

    proofs. Our approach to backward error analysis is based on a simple
    recursive definition of the modified vector fields that does not
    require explicit Taylor series expansion of the numerical method
    and the corresponding flow maps as in the above-cited works. As

  abstract = {Numerical resonance artifacts have become recognized recently as a
    limiting factor to increasing the timestep in multiple-timestep
    (MTS) biomolecular dynamics simulations. At certain timesteps correlated
    to internal motions (e.g., 5 fs, around half the period of the fastest
    bond stretch, T-min), visible inaccuracies or instabilities can
    occur. Impulse-MTS schemes are vulnerable to these resonance errors
    since large energy pulses are introduced to the governing dynamics
    equations when the slow forces are evaluated. We recently showed
    that such resonance artifacts can be masked significantly by applying
    extrapolative splitting to stochastic dynamics. Theoretical and
    numerical analyses of force-splitting integrators based on the Verlet
    discretization are reported here for linear models to explain these
    observations and to suggest how to construct effective integrators
    for biomolecular dynamics that balance stability with accuracy.
    Analyses for Newtonian dynamics demonstrate the severe resonance
    patterns of the Impulse splitting, with this severity worsening
    with the outer timestep. Delta t: Constant Extrapolation is generally
    unstable, but the disturbances do not grow with Delta t. Thus. the
    stochastic extrapolative combination can counteract generic instabilities
    and largely alleviate resonances with a sufficiently strong Langevin
    heat-bath coupling (gamma), estimates for which are derived here
    based on the fastest and slowest motion periods. These resonance
    results generally hold for nonlinear test systems: a water tetramer
    and solvated protein. Proposed related approaches such as Extrapolation/Correction
    and Midpoint Extrapolation work better than Constant Extrapolation
    only for timesteps less than T-min/2. An effective extrapolative
    stochastic approach for biomolecules that balances long-timestep
    stability with good accuracy for the fast subsystem is then applied
    to a biomolecule using a three-class partitioning: the medium forces
    are treated by Midpoint Extrapolation via position Verlet, and the
    slow forces are incorporated by Constant Extrapolation. The resulting
    algorithm (LN) performs well on a solvated protein system in terms
    of thermodynamic properties and yields an order of magnitude speedup
    with respect to single-timestep Langevin trajectories. Computed
    spectral density functions also show how the Newtonian modes can
    be approximated by using a small gamma in the range Of 5-20 ps(-1).

  abstract = {The following integration methods for special second-order ordinary
    differential equations are studied: leapfrog, implicit midpoint,
    trapezoid, Stormer-Verlet, and Cowell-Numerov. We show that all
    are members, or equivalent to members, of a one-parameter family
    of schemes. Some methods have more than one common form, and we
    discuss a systematic enumeration of these forms. We also present
    a stability and accuracy analysis based on the idea of ''modified
    equations'' and a proof of symplecticness. It follows that Cowell-Numerov
    and ''LIM2'' (a method proposed by Zhang and Schlick) are symplectic.
    A different interpretation of the values used by these integrators
    leads to higher accuracy and better energy conservation. Hence,
    we suggest that the straightforward analysis of energy conservation
    is misleading.},

  abstract = {Recently a microscopic theory for the dynamics of suspensions of long
    thin rigid rods was presented, confirming and expanding the well-known
    theory by Doi and Edwards [The Theory of Polymer Dynamics (Clarendon,
    Oxford, 1986)] and Kuzuu [J. Phys. Soc. Jpn. 52, 3486 (1983)]. Here
    this theory is put to the test by comparing it against computer
    simulations. A Brownian dynamics simulation program was developed
    to follow the dynamics of the rods, with a length over a diameter
    ratio of 60, on the Smoluchowski time scale. The model accounts
    for excluded volume interactions between rods, but neglects hydrodynamic
    interactions. The self-rotational diffusion coefficients D-r(phi)
    of the rods were calculated by standard methods and by a new, more
    efficient method based on calculating average restoring torques.
    Collective decay of orientational order was calculated by means
    of equilibrium and nonequilibrium simulations. Our results show
    that, for the currently accessible volume fractions, the decay times
    in both cases are virtually identical. Moreover, the observed decay
    of diffusion coefficients with volume fraction is much quicker than
    predicted by the theory, which is attributed to an oversimplification
    of dynamic correlations in the theory. (c) 2005 American Institute

    the bilayer is stable throughout the 1550-ps simulation and have
    demonstrated convergence of the system dimensions. Several important
    aspects of the bilayer structure have been investigated and compared
    favorably with experimental results. For example, the average positions
    of specific carbon atoms along the bilayer normal agree well with
    neutron diffraction data, and the electron density profile is in
    accord with x-ray diffraction results. The hydrocarbon chain deuterium
    order parameters agree reasonably well with NMR results for the
    middles of the chains, but the simulation predicts too much order
    at the chain ends. In spite of the deviations in the order parameters,
    the hydrocarbon chain packing density appears to be essentially
    correct, inasmuch as the area/lipid and bilayer thickness are in
    agreement with the most refined experimental estimates. The deuterium
    order parameters for the glycerol and choline groups, as well as
    the phosphorus chemical shift anisotropy, are in qualitative agreement
    with those extracted from NMR measurements.},

  abstract = {The effects of longitudinal quadrupole moments on the formation of
    liquid crystalline phases are studied by means of constant NPT Monte
    Carlo simulation methods. The popular Gay-Berne model mesogen is
    used as the reference fluid, which displays the phase sequences
    isotropic-smectic A-smectic B and isotropic-smectic B at high (T*=2.0)
    and low (T*=1.5) temperatures, respectively. With increasing quadrupole
    magnitude the smectic phases are observed to be stabilized with
    respect to the isotropic liquid, while the smectic B is destabilized
    with respect to the smectic A. At the lower temperature, a sufficiently
    large quadrupole magnitude results in the injection of the smectic
    A phase into the phase sequence and the replacement of the smectic
    B phase by the tilted smectic J phase. The nematic phase is also
    injected into the phase sequence at both temperatures considered,
    and ultimately for sufficiently large quadrupole magnitudes no coherent
    layered structures were observed. The stabilization of the smectic
    A phase supports the commonly held belief that, while the inclusion
    of polar groups is not a prerequisite for the formation of the smectic
    A phase, quadrupolar interactions help to increase the temperature
    and pressure range for which the smectic A phase is observed. The
    quality of the layered structure is worsened with increasing quadrupole
    magnitude. This behavior, along with the injection of the nematic
    phase into the phase sequence, indicate that the general tendency
    of the quadrupolar interactions is to destabilize the layered structure.
    A pressure dependence upon the smectic layer spacing is observed.
    This behavior is in much closer agreement with experimental findings
    than has been observed previously for nonpolar Gay-Berne and hard
    spherocylinder models. (C) 2003 American Institute of Physics.},

  abstract = {Based on a recent result showing that the net Coulomb potential in
    condensed ionic systems is rather short ranged, an exact and physically
    transparent method permitting the evaluation of the Coulomb potential
    by direct summation over the r(-1) Coulomb pair potential is presented.
    The key observation is that the problems encountered in determining
    the Coulomb energy by pairwise, spherically truncated r(-1) summation
    are a direct consequence of the fact that the system summed over
    is practically never neutral. A simple method is developed that
    achieves charge neutralization wherever the r(-1) pair potential
    is truncated. This enables the extraction of the Coulomb energy,
    forces, and stresses from a spherically truncated, usually charged
    environment in a manner that is independent of the grouping of the
    pair terms. The close connection of our approach with the Ewald
    method is demonstrated and exploited, providing an efficient method
    for the simulation of even highly disordered ionic systems by direct,
    pairwise r(-1) summation with spherical truncation at rather short
    range, i.e., a method which fully exploits the short-ranged nature
    of the interactions in ionic systems. The method is validated by
    simulations of crystals, liquids, and interfacial systems, such
    as free surfaces and grain boundaries. (C) 1999 American Institute
