Optimization Task

Special kinds of structures exhibit repetitive patterns that can be used in the process of structural analysis in order to decrease the required computational time. This is especially helpful when a structure should be analyzed numerous times as in the structural optimization problems. In this article, weight optimization of cyclically symmetric spatial trusses subjected to frequency constraints is performed utilizing such repetitive patterns. Large initial eigenproblems are first decomposed into smaller and less time-consuming problems using an efficient block diagonalization technique. A recently developed meta-heuristic method, cyclical parthenogenesis algorithm, is then utilized to perform the optimization task. Three numerical examples are optimized to illustrate the viability and efficiency of the proposed method.

Polymorphic Microsatellite

We used polymorphic microsatellite markers to look for recombination during parthenogenetic oogenesis between the X chromosomes of aphids of the tribe Macrosiphini. We examined the X chromosome because it comprises ∼25% of the genome and previous cytological observations of chromosome pairing and nucleolar organizer (NOR) heteromorphism suggest recombination, although the same is not true for autosomes. A total of 564 parthenogenetic females of Myzus clones with three distinct reproductive modes (cyclical parthenogenesis, obligate parthenogenesis and obligate parthenogenesis with male production) were genotyped at three informative X-linked loci. Also, parthenogenetically produced males from clones encompassing the full range of male-producing reproductive strategies were genotyped. These included 391 Myzus persicae males that were genotyped at three X-linked loci and 538 males from Sitobion clones that were genotyped at five informative X-linked loci. Our results show no departure from clonality in parthenogenetic generations of aphids of the tribe Macrosiphini: no recombinant genotypes were observed in parthenogenetically produced males or females.
