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

52 abstract = {Time series analysis tools are employed on the principal modes obtained
53 from the C-alpha trajectories from two independent molecular-dynamics
54 simulations of alpha-amylase inhibitor (tendamistat). Fluctuations
55 inside an energy minimum (intraminimum motions), transitions between
56 minima (interminimum motions), and relaxations in different hierarchical
57 energy levels are investigated and compared with those encountered
58 in vacuum by using different sampling window sizes and intervals.
59 The low-frequency low-indexed mode relationship, established in
60 vacuum, is also encountered in water, which shows the reliability
61 of the important dynamics information offered by principal components
62 analysis in water. It has been shown that examining a short data
63 collection period (100 ps) may result in a high population of overdamped
64 modes, while some of the low-frequency oscillations (< 10 cm(-1))
65 can be captured in water by using a longer data collection period
66 (1200 ps). Simultaneous analysis of short and long sampling window
67 sizes gives the following picture of the effect of water on protein
68 dynamics. Water makes the protein lose its memory: future conformations
69 are less dependent on previous conformations due to the lowering
70 of energy barriers in hierarchical levels of the energy landscape.
71 In short-time dynamics (< 10 ps), damping factors extracted from
72 time series model parameters are lowered. For tendamistat, the friction
73 coefficient in the Langevin equation is found to be around 40-60
74 cm(-1) for the low-indexed modes, compatible with literature. The
75 fact that water has increased the friction and that on the other
76 hand has lubrication effect at first sight contradicts. However,
77 this comes about because water enhances the transitions between
78 minima and forces the protein to reduce its already inherent inability
79 to maintain oscillations observed in vacuum. Some of the frequencies
80 lower than 10 cm(-1) are found to be overdamped, while those higher
81 than 20 cm(-1) are slightly increased. As for the long-time dynamics
82 in water, it is found that random-walk motion is maintained for
83 approximately 200 ps (about five times of that in vacuum) in the
84 low-indexed modes, showing the lowering of energy barriers between
85 the higher-level minima.},

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

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

474 paper, we first address several crucial methodological problems
475 of such simulations: (i) the influence of finite-element discretization
476 on simulated dynamics, (ii) choice between Ito and Stratonovich
477 stochastic calculi by the solution of micromagnetic stochastic equations
478 of motion and (iii) non-trivial correlation properties of the random
479 (thermal) field. Next, we discuss several examples to demonstrate
480 the great potential of the Langevin dynamics for studying fast remagnetization
481 processes in technically relevant applications: we present numerical
482 analysis of equilibrium magnon spectra in patterned structures,
483 study thermal noise effects on the magnetization dynamics of nanoelements
484 in pulsed fields and show some results for a remagnetization dynamics

577 and computer simulation. The molecules are composed of two hard
578 spherocylinders, with length-to-breadth ratio L/D, joined by their
579 ends at an angle 180 degrees - gamma. For L/D = 2 and gamma = 0,10,20
580 degrees, the simulations show isotropic, nematic, smectic, and solid
581 phases. For L/D = 2 and gamma = 30 degrees, only isotropic, nematic,
582 and solid phases are in evidence, which suggests that there is a
583 nematic-smectic-solid triple point at an angle in the range 20 degrees
584 < gamma < 30 degrees. In all of the orientationally ordered fluid
585 phases the order is purely uniaxial. For gamma = 10 degrees and
586 20 degrees, at the studied densities, the solid is also uniaxially
587 ordered, whilst for gamma = 30 degrees the solid layers are biaxially
588 ordered. For L/D = 2 and gamma = 60 degrees and 90 degrees we find
589 no spontaneous orientational ordering. This is shown to be due to
590 the interlocking of dimer pairs which precludes alignment. We find
591 similar results for L/D = 9.5 and gamma = 72 degrees, where an isotropic-biaxial
592 nematic transition is predicted by Onsager theory. Simulations in
593 the biaxial nematic phase show it to be at least mechanically stable
594 with respect to the isotropic phase, however. We have compared the
595 quasi-exact simulation results in the isotropic phase with the predicted
596 equations of state from three theories: the virial expansion containing
597 the second and third virial coefficients; the Parsons-Lee equation
598 of state; an application of Wertheim's theory of associating fluids
599 in the limit of infinite attractive association energy. For all
600 of the molecule elongations and geometries we have simulated, the
601 Wertheim theory proved to be the most accurate. Interestingly, the
602 isotropic equation of state is virtually independent of the dimer
603 bond angle-a feature that is also reflected in the lack of variation
604 with angle of the calculated second and third virial coefficients.

915 several simulation protocols are employed both for the free enzyme
916 in vacuo and for the free enzyme with some solvent modeling: high-temperature
917 Langevin dynamics simulations, sampling by a #dynamics##driver#
918 approach, and potential-energy surface calculations. Our focus is
919 on obtaining the energy barrier to the enzyme's motion and establishing
920 the nature of the loop movement. Previous calculations did not determine
921 this energy barrier and the effect of solvent on the barrier. High-temperature
922 molecular dynamics simulations and crystallographic studies have
923 suggested a rigid-body motion with two hinges located at both ends
924 of the loop; Brownian dynamics simulations at room temperature pointed
925 to a very flexible behavior. The present simulations and analyses
926 reveal that although solute/solvent hydrogen bonds play a crucial
927 role in lowering the energy along the pathway, there still remains
928 a high activation barrier, This finding clearly indicates that,
929 if the loop opens and closes in the absence of a substrate at standard
930 conditions (e.g., room temperature, appropriate concentration of
931 isomerase), the time scale for transition is not in the nanosecond
932 but rather the microsecond range. Our results also indicate that

952 symmetry. Standard numerical integration methods destroy both properties,
953 introducing nonphysical dynamical behavior such as numerically induced
954 dissipative states and drift in the energy during long term simulations.
955 This article describes the construction, implementation, and practical
956 application of fast explicit symplectic-reversible integrators for
957 multiple rigid body molecular simulations, These methods use a reduction
958 to Euler equations for the free rigid body, together with a symplectic
959 splitting technique. In every time step, the orientational dynamics
960 of each rigid body is integrated by a sequence of planar rotations.
961 Besides preserving the symplectic and reversible structures of the
962 flow, this scheme accurately conserves the total angular momentum
963 of a system of interacting rigid bodies. Excellent energy conservation
964 fan be obtained relative to traditional methods, especially in long-time
965 simulations. The method is implemented in a research code, ORIENT
966 and compared with a quaternion/extrapolation scheme for the TIP4P
967 model of water. Our experiments show that the symplectic-reversible
968 scheme is far superior to the more traditional quaternion method.

1292 with an application to bovine pancreatic trypsin inhibitor (BPTI),
1293 is reported. The unfolding and refolding of the native structure
1294 of the protein are characterized by the dimensions of the protein,
1295 expressed in terms of the three principal radii of the structure
1296 considered as an ellipsoid. A dynamic equation, describing the variations
1297 of the principal radii on the unfolding path, and a numerical procedure
1298 to solve this equation are proposed. Expanded and distorted conformations
1299 are refolded to the native structure by a dimensional-constraint
1300 energy minimization procedure. A unique and reproducible unfolding
1301 pathway for an intermediate of BPTI lacking the [30,51] disulfide
1302 bond is obtained. The resulting unfolded conformations are extended;
1303 they contain near-native local structure, but their longest principal
1304 radii are more than 2.5 times greater than that of the native structure.
1305 The most interesting finding is that the majority of expanded conformations,
1306 generated under various conditions, can be refolded closely to the
1307 native structure, as measured by the correct overall chain fold,
1308 by the rms deviations from the native structure of only 1.9-3.1
1309 angstrom, and by the energy differences of about 10 kcal/mol from
1310 the native structure. Introduction of the [30,51] disulfide bond
1311 at this stage, followed by minimization, improves the closeness
1312 of the refolded structures to the native structure, reducing the
1313 rms deviations to 0.9-2.0 angstrom. The unique refolding of these
1314 expanded structures over such a large conformational space implies
1315 that the folding is strongly dictated by the interactions in the
1316 amino acid sequence of BPTI. The simulations indicate that, under
1317 conditions that favor a compact structure as mimicked by the volume
1318 constraints in our algorithm; the expanded conformations have a
1319 strong tendency to move toward the native structure; therefore,
1320 they probably would be favorable folding intermediates. The results
1321 presented here support a general model for protein folding, i.e.,
1322 progressive formation of partially folded structural units, followed
1323 by collapse to the compact native structure. The general applicability
1324 of the procedure is also discussed.},

1342 paper, we try to understand the form and origin of the anharmonicities,
1343 with the principal aim of gaining a better understanding of the
1344 principal motion types, but also in order to develop more efficient
1345 numerical methods for simulating neutron scattering spectra of large
1346 proteins. First, we decompose a molecular dynamics (MD) trajectory
1347 of 1.5 ns for a C-phycocyanin dimer surrounded by a layer of water
1348 into three contributions that we expect to be independent: the global
1349 motion of the residues, the rigid-body motion of the sidechains
1350 relative to the backbone, and the internal deformations of the sidechains.
1351 We show that they are indeed almost independent by verifying the
1352 factorization of the incoherent intermediate scattering function.
1353 Then, we show that the global residue motions, which include all
1354 large-scale backbone motions, can be reproduced by a simple harmonic
1355 model which contains two contributions: a short-time vibrational
1356 term, described by a standard normal mode calculation in a local
1357 minimum, and a long-time diffusive term, described by Brownian motion
1358 in an effective harmonic potential. The potential and the friction
1359 constants were fitted to the MD data. The major anharmonic contribution
1360 to the incoherent intermediate scattering function comes from the
1361 rigid-body diffusion of the sidechains. This model can be used to
1362 calculate scattering functions for large proteins and for long-time
1363 scales very efficiently, and thus provides a useful complement to
1364 MD simulations, which are best suited for detailed studies on smaller
1365 systems or for shorter time scales. (C) 2000 Elsevier Science B.V.

1387 phenyl]ethyl]carbonyl]-3-sn-PC (DPH-PC), where the fluorophores
1388 are located in the hydrophobic core of the lipid bilayer, the introduction
1389 of gramicidin reduced the fluorescence lifetime, indicative of an
1390 increased presence of water in the bilayer. Since a high protein:lipid
1391 ratio was used, the fluorophores were forced to be adjacent to the
1392 protein hydrophobic surface, hence the presence of water in this
1393 region could be inferred. Cholesterol is known to reduce the water
1394 content of lipid bilayers and this effect was maintained at the
1395 protein-lipid interface with both gramicidin and apocytochrome C,
1396 again suggesting hydration in this region. The second approach was
1397 to use the fluorescence enhancement induced by exchanging deuterium
1398 oxide (D2O) for H2O. Both the fluorescence intensities of trimethylammonium-DPH,
1399 located in the lipid head group region, and of the gramicidin intrinsic
1400 tryptophans were greater in a D2O buffer compared with H2O, showing
1401 that the fluorophores were exposed to water in the bilayer at the
1402 protein-lipid interface. In the presence of cholesterol the fluorescence
1403 intensity ratio of D2O to H2O decreased, indicating a removal of
1404 water by the cholesterol, in keeping with the lifetime data. Altered
1405 hydration at the protein-lipid interface could affect conformation,
1406 thereby offering a new route by which membrane protein functioning
1407 may be modified.},

1469 damping to stabilize long time step integrators for Newtonian molecular
1470 dynamics. More specifically, stable and accurate integrations are
1471 obtained for damping coefficients that are only a few percent of
1472 the natural decay rate of processes of interest, such as the velocity
1473 autocorrelation function. Two new multiple time stepping integrators,
1474 Langevin Molly (LM) and Brunger-Brooks-Karplus-Molly (BBK-M), are
1475 introduced in this paper. Both use the mollified impulse method
1476 for the Newtonian term. LM uses a discretization of the Langevin
1477 equation that is exact for the constant force, and BBK-M uses the
1478 popular Brunger-Brooks-Karplus integrator (BBK). These integrators,
1479 along with an extrapolative method called LN, are evaluated across
1480 a wide range of damping coefficient values. When large damping coefficients
1481 are used, as one would for the implicit modeling of solvent molecules,
1482 the method LN is superior, with LM closely following. However, with
1483 mild damping of 0.2 ps(-1), LM produces the best results, allowing
1484 long time steps of 14 fs in simulations containing explicitly modeled
1485 flexible water. With BBK-M and the same damping coefficient, time
1486 steps of 12 fs are possible for the same system. Similar results
1487 are obtained for a solvated protein-DNA simulation of estrogen receptor
1488 ER with estrogen response element ERE. A parallel version of BBK-M
1489 runs nearly three times faster than the Verlet-I/r-RESPA (reversible
1490 reference system propagator algorithm) when using the largest stable
1491 time step on each one, and it also parallelizes well. The computation
1492 of diffusion coefficients for flexible water and ER/ERE shows that
1493 when mild damping of up to 0.2 ps-1 is used the dynamics are not

1521 algorithms are variational in the sense of the Veselov formulation
1522 of discrete mechanics. Such variational algorithms are well known
1523 to be symplectic and momentum preserving and to often have excellent
1524 global energy behaviour. This analytical result is verified through
1525 numerical examples and is believed to be one of the primary reasons
1526 that this class of algorithms performs so well. Second, we develop
1527 algorithms for mechanical systems with forcing, and in particular,
1528 for dissipative systems. In this case, we develop integrators that
1529 are based on a discretization of the Lagrange d'Alembert principle
1530 as well as on a variational formulation of dissipation. It is demonstrated

1576 in quaternions prevents the use of a standard leapfrog (Verlet)
1577 integrator, so nonsymplectic Runge-Kutta, multistep, or extrapolation
1578 methods are generally used, This is unfortunate since symplectic
1579 methods like Verlet exhibit superior energy conservation in long-time
1580 integrations. In this article, we describe an alternative method,
1581 which we call RSHAKE (for rotation-SHAKE), in which the entire rotation
1582 matrix is evolved (using the scheme of McLachlan and Scovel [J.
1583 Nonlin. Sci, 16 233 (1995)]) in tandem with the particle positions.
1584 We employ a fast approximate Newton solver to preserve the orthogonality
1585 of the rotation matrix. We test our method on a system of soft-sphere
1586 dipoles and compare with quaternion evolution using a 4th-order
1587 predictor-corrector integrator, Although the short-time error of
1588 the quaternion algorithm is smaller for fixed time step than that
1589 for RSHAKE, the quaternion scheme exhibits an energy drift which
1590 is not observed in simulations with RSHAKE, hence a fixed energy
1591 tolerance can be achieved by using a larger time step, The superiority
1592 of RSHAKE increases with system size. (C) 1997 American Institute

1827 nature of the membrane. The calculated excess free energy profile
1828 has a shallow slope and a maximum height of 26 kJ/mol. The diffusion
1829 rate is highest in the middle of the membrane where the lipid density
1830 is low. In the interfacial region almost all water molecules are
1831 bound by the lipid headgroups, and the diffusion turns out to be
1832 1 order of magnitude smaller. The total transport process is essentially
1833 determined by the free energy barrier. The rate-limiting step is
1834 the permeation through the dense part of the lipid tails, where
1835 the resistance is highest. We found a permeation rate of 7(+/-3)
1836 x 10(-2) cm/s at 350 K, comparable to experimental values for DPPC
1837 membranes, if corrected for the temperature of the simulation. Taking
1838 the inhomogeneity of the membrane into account, we define a new
1839 ''four-region'' model which seems to be more realistic than the
1840 ''two-phase'' solubility-diffusion model.},

1857 and discrete mechanics and field theories. Using multisymplectic
1858 geometry, we show that the existence of the fundamental geometric
1859 structures as well as their preservation along solutions can be
1860 obtained directly from the variational principle. In particular,
1861 we prove that a unique multisymplectic structure is obtained by
1862 taking the derivative of an action function, and use this structure
1863 to prove covariant generalizations of conservation of symplecticity
1864 and Noether's theorem. Natural discretization schemes for PDEs,
1865 which have these important preservation properties, then follow
1866 by choosing a discrete action functional. In the case of mechanics,
1867 we recover the variational symplectic integrators of Veselov type,
1868 while for PDEs we obtain covariant spacetime integrators which conserve
1869 the corresponding discrete multisymplectic form as well as the discrete
1870 momentum mappings corresponding to symmetries. We show that the
1871 usual notion of symplecticity along an infinite-dimensional space
1872 of fields can be naturally obtained by making a spacetime split.
1873 All of the aspects of our method are demonstrated with a nonlinear
1874 sine-Gordon equation, including computational results and a comparison

2053 transcription ensemble. Following a sharp rise at early times, the

2056 stress is increasingly partitioned to writhe. The magnitude of writhe

2294 magnetic moment is numerically solved (properly observing the customary
2295 interpretation of it as a Stratonovich stochastic differential equation),
2296 in order to study the dynamics of magnetic nanoparticles. The corresponding
2297 Langevin-dynamics approach allows for the study of the fluctuating
2298 trajectories of individual magnetic moments, where we have encountered
2299 remarkable phenomena in the overbarrier rotation process, such as
2300 crossing-back or multiple crossing of the potential barrier, rooted
2301 in the gyromagnetic nature of the system. Concerning averaged quantities,
2302 we study the linear dynamic response of the archetypal ensemble
2303 of noninteracting classical magnetic moments with axially symmetric
2304 magnetic anisotropy. The results are compared with different analytical
2305 expressions used to model the relaxation of nanoparticle ensembles,
2306 assessing their accuracy. It has been found that, among a number
2307 of heuristic expressions for the linear dynamic susceptibility,
2308 only the simple formula proposed by Shliomis and Stepanov matches
2309 the coarse features of the susceptibility reasonably. By comparing
2310 the numerical results with the asymptotic formula of Storonkin {Sov.

2515 backward error analysis can be used to show that a symplectic method
2516 will conserve energy over exponentially long periods of time. Such
2517 results are typically based on two aspects of backward error analysis:
2518 (i) It can be shown that the modified vector fields have some qualitative
2519 properties which they share with the given problem and (ii) an estimate
2520 is given for the difference between the best interpolating vector
2521 field and the numerical method. These aspects have been investigated
2522 recently, for example, by Benettin and Giorgilli in [J. Statist.

2528 recursive definition of the modified vector fields that does not
2529 require explicit Taylor series expansion of the numerical method
2530 and the corresponding flow maps as in the above-cited works. As

2572 species (high barrier for Na+, low barrier for K+, almost free diffusion
2573 for water), different methods are used to calculate the mobilities.
2574 By use of activated dynamics and a potential of mean force determined
2575 previously (Roux, B.; Karplus, M. Biophys. J. 1991, 59, 961), the
2576 barrier crossing rate of Na+ ion is determined. The motion of Na+
2577 at the transition state is controlled by local interactions and
2578 collisions with the neighboring carbonyls and the two nearest water
2579 molecules. There are significant deviations from transition-state
2580 theory; the transmission coefficient is equal to 0.11. The water
2581 and K+ motions are found to be well described by a diffusive model;
2582 the motion of K+ appears to be controlled by the diffusion of water.
2583 The time-dependent friction functions of Na+ and K+ ions in the
2584 periodic beta-helix are calculated and analyzed by using a generalized
2585 Langevin equation approach. Both Na+ and K+ suffer many rapid collisions,
2586 and their dynamics is overdamped and noninertial. Thus, the selectivity

2672 abstract = {Numerical resonance artifacts have become recognized recently as a
2673 limiting factor to increasing the timestep in multiple-timestep
2674 (MTS) biomolecular dynamics simulations. At certain timesteps correlated
2675 to internal motions (e.g., 5 fs, around half the period of the fastest
2676 bond stretch, T-min), visible inaccuracies or instabilities can
2677 occur. Impulse-MTS schemes are vulnerable to these resonance errors
2678 since large energy pulses are introduced to the governing dynamics
2679 equations when the slow forces are evaluated. We recently showed
2680 that such resonance artifacts can be masked significantly by applying
2681 extrapolative splitting to stochastic dynamics. Theoretical and
2682 numerical analyses of force-splitting integrators based on the Verlet
2683 discretization are reported here for linear models to explain these
2684 observations and to suggest how to construct effective integrators
2685 for biomolecular dynamics that balance stability with accuracy.
2686 Analyses for Newtonian dynamics demonstrate the severe resonance
2687 patterns of the Impulse splitting, with this severity worsening
2688 with the outer timestep. Delta t: Constant Extrapolation is generally
2689 unstable, but the disturbances do not grow with Delta t. Thus. the
2690 stochastic extrapolative combination can counteract generic instabilities
2691 and largely alleviate resonances with a sufficiently strong Langevin
2692 heat-bath coupling (gamma), estimates for which are derived here
2693 based on the fastest and slowest motion periods. These resonance
2694 results generally hold for nonlinear test systems: a water tetramer
2695 and solvated protein. Proposed related approaches such as Extrapolation/Correction
2696 and Midpoint Extrapolation work better than Constant Extrapolation
2697 only for timesteps less than T-min/2. An effective extrapolative
2698 stochastic approach for biomolecules that balances long-timestep
2699 stability with good accuracy for the fast subsystem is then applied
2700 to a biomolecule using a three-class partitioning: the medium forces
2701 are treated by Midpoint Extrapolation via position Verlet, and the
2702 slow forces are incorporated by Constant Extrapolation. The resulting
2703 algorithm (LN) performs well on a solvated protein system in terms
2704 of thermodynamic properties and yields an order of magnitude speedup
2705 with respect to single-timestep Langevin trajectories. Computed
2706 spectral density functions also show how the Newtonian modes can
2707 be approximated by using a small gamma in the range Of 5-20 ps(-1).

2904 this theory is put to the test by comparing it against computer

2906 to follow the dynamics of the rods, with a length over a diameter
2907 ratio of 60, on the Smoluchowski time scale. The model accounts
2908 for excluded volume interactions between rods, but neglects hydrodynamic
2909 interactions. The self-rotational diffusion coefficients D-r(phi)
2910 of the rods were calculated by standard methods and by a new, more
2911 efficient method based on calculating average restoring torques.
2912 Collective decay of orientational order was calculated by means
2913 of equilibrium and nonequilibrium simulations. Our results show
2914 that, for the currently accessible volume fractions, the decay times
2915 in both cases are virtually identical. Moreover, the observed decay
2916 of diffusion coefficients with volume fraction is much quicker than

3037 isotropic-smectic A-smectic B and isotropic-smectic B at high (T*=2.0)
3038 and low (T*=1.5) temperatures, respectively. With increasing quadrupole
3039 magnitude the smectic phases are observed to be stabilized with
3040 respect to the isotropic liquid, while the smectic B is destabilized
3041 with respect to the smectic A. At the lower temperature, a sufficiently
3042 large quadrupole magnitude results in the injection of the smectic
3043 A phase into the phase sequence and the replacement of the smectic
3044 B phase by the tilted smectic J phase. The nematic phase is also
3045 injected into the phase sequence at both temperatures considered,
3046 and ultimately for sufficiently large quadrupole magnitudes no coherent
3047 layered structures were observed. The stabilization of the smectic
3048 A phase supports the commonly held belief that, while the inclusion

3076 condensed ionic systems is rather short ranged, an exact and physically
3077 transparent method permitting the evaluation of the Coulomb potential

3079 The key observation is that the problems encountered in determining
3080 the Coulomb energy by pairwise, spherically truncated r(-1) summation
3081 are a direct consequence of the fact that the system summed over
3082 is practically never neutral. A simple method is developed that
3083 achieves charge neutralization wherever the r(-1) pair potential
3084 is truncated. This enables the extraction of the Coulomb energy,
3085 forces, and stresses from a spherically truncated, usually charged
3086 environment in a manner that is independent of the grouping of the
3087 pair terms. The close connection of our approach with the Ewald
3088 method is demonstrated and exploited, providing an efficient method
3089 for the simulation of even highly disordered ionic systems by direct,
3090 pairwise r(-1) summation with spherical truncation at rather short
3091 range, i.e., a method which fully exploits the short-ranged nature
