Functional Simulation

This step is equivalent to software debugging. The HDL simulator (debugger) is provided for both functional and timing simulations. The HDL simulator is ModelSim from ModelTech, 

It has both a graphic user interface (GUI) and scripting capability.

Fig. 6. Snapshot from a dynamic density functional simulation of the self-organisation of the block copolymer PL64 (containing 30 propylene oxide rmd 26 ethylene oxide units (EO)i3(PO)3o(EO)i3) in 70% aqueous solution. The simulation was carried out during 6250 time steps on a 64 x 64 x 64 grid (courtesy of B.A.C. van Vlimmeren and J.G.E.M. Praaije, Groningen).

CAM-PC is a general purpose CA software simulation environment based on CAM-6, Designed by members of the GENOME Project at Eotvos University in Hungary, the first version of CAM-PC extends the possibilities of CAM-6 but is not yet fully compatible with it. The primary addition is support for 8 bit planes, increasing the size of CAM-6 s ccdl-statc alphabet to 256, The laudable purpose behind the project is to provide inexpensive but otherwise fully functional simulation tools for amateur researchers unable to afford faster dedicatcxl hardware.

Studies on molecular recognition by artificial receptors are thus one of the most important approaches to such characterization in relation to supramolecular chemistry [4]. Functional simulation of intracellular receptors in aqueous media has been actively carried out with attention to various noncovalent host-guest interactions, such as hydrophobic, electrostatic, hydrogen-bonding, charge-transfer, and van der Waals modes [5-10]. On the other hand, molecular recognition by artificial cell-surface receptors embedded in supramolecular assemblies has been scarcely studied up to the present time, except for channel-linked receptors [11-13]. 

We have already reported that synthetic peptide lipids, having ot-amino acid residuefs) interposed between a polar head moiety and a hydrophobic doublechain segment, can be used as models for functional simulation of biomembranes [23]. On this ground, we are to clarify molecular recognition specificity by supramolecular assemblies formed in combination of the macrocyclic receptors with the peptide lipid as artificial cell-surface receptors.

The computer models described provide a functional simulation of SEC-viscometry-LS analysis of linear polymers. The results for the Flory-Schulz MWD are in qualitative agreement with previous results for the Wesslau MWD. Both models emphasize the importance of determining the correct volume offset between the concentration detector and molecular weight-sensitive detectors. For the Flory-Schulz model, the peak shape, as well as the peak elution volume, can provide information about molecular weight polydispersity. Future work will extend the model to incorporate peak skew and polymer branching.

Analysis of polarized EXAFS data, (a) EXAFS radial structure functions for irom oxide precipitates on quartz single crystal surfaces, r and m refer to the (1011 )and (1120) surface planes of quartz. The parallel and perpendicular refer to the polarization direction of the X-ray beam and thus the probe direction of the EXAFS scattering process, (b) Raw polarized EXAFS and fits for the same samples in (a), (c) Polarized stracture function simulations. Top radial stracture function for a single Fe atom within a 50-atom hematite crystal with [0001] orientation. Middle Same for 20-atom crystal. Bottom Weighted average of all Fe stracture func-tions in the 20-atom crystal. The analysis suggests highly textrrred hematite-like nanocrystals on the quartz surface but no epitaxial relationship.

A method that is Bayesian in nature is that proposed by Racine-Poon (38). The method uses the estimates of the individual parameters j and asymptotic variance matrix Vj obtained from the individual fits, with very weak assumptions about the prior distribution of the population parameters to calculate a posterior density function from which and Q can be obtained. In an iterative method suggested by Dempster et al. (39) the EM algorithm is used to calculate the posterior density function. Simulation studies in which several varying and realistic conditions were...
