Comparatively, better solutions are kept at higher positions, while the bad ones are at kept at the lowest position in the solution matrix.
The special design of the beam sweeping system, enables both ion beams to scan the target surface simultaneously in synchronous mode, i.e. both ion spots are kept at coincident positions over the target.
Further, every crystal structure was minimized for 500 steps with the steepest descent minimizer as implemented in SYBYL with the backbone atoms kept at fixed positions in order to fix close contacts, followed by 2000 steps conjugate gradient minimization requested for an overall better starting structure.
Calculations to obtain final results employed the MO/MO basis-set combination B3LYP/cc-pVTZ B3LYP/3-21G. Only the central molecule was optimized, whereas the surrounding 16 asymmetric units were kept at fixed positions.
The stop codons and Trp are kept at their positions in the standard code table (Fig. 1); 2. The assignments of the 8 amino acids (Ser, Leu, Pro, Arg, Thr, Val, Ala, Gly) that are encoded by four-codon series are distributed randomly among the 14 blocks of the code table.
A floating body, containing a permanent magnet, is kept at constant position in a tube by an external solenoid.
A proof mass made of permanent magnet is appended to the floating gate, which is kept at initial position by controlled magnetic field.
Total ascitic fluid was drawn and kept at standing position in a 50 ml sterile tube for at least 2 hrs for settling down the tumor cells and then clear fluid from the upper zone was collected.
This is a direct consequence of the fact that two opposite positions on the chromosome (ori and ter) are kept at fixed opposite positions in the cell.
Considering the RVE of referential height (h_{i}) (Figure 11), all fiber node points at the upper face are vertically shifted with magnitude u, i.e., (mathbf{r}^{nu}=mathbf {r}^{mathbf{0}nu}+umathbf{e}_{mathbf{z}}), (nuinmathcal{N}_{B,up}), while the ones at the lower face are kept at the referential positions.
