We present several new eecient architectures to solve the hidden surface problem in the feature domain. All the architectures operate on segments (instead of pix-els) and create a list of visible segments for each scan line. We present two new semi-systolic architectures consisting of an array of M processors, where M is the maximum number of overlapping segments. Both ar-chitectures require pr...

High-spin states of the odd-odd nucleus $^{168}\mathrm{Lu}$ were populated in $^{123}\mathrm{Sb}(^{48}\mathrm{Ca},3\mathrm{n})^{168}\mathrm{Lu}$ reaction at a beam energy 203 MeV and decay $\ensuremath{\gamma}$ rays measured using Gammasphere spectrometer array. The level scheme has been extended from spin 27 to 50 $\ensuremath{\hbar}$, three new rotational bands have added. A number interband ...

a positive solution of the problem of the existence of nontrivial pairs of zero-divisors in group rings of free burnside groups of sufficiently large odd periods $n>10^{10}$ obtained previously by s. v. ivanov and r. mikhailov extended to all odd periods $ngeq 665$‎.
