Chromosome numbers in antlions (Myrmeleontidae) and owlflies (Ascalaphidae) (Insecta, Neuroptera)
A short review of main cytogenetic features of insects belonging to the sister neuropteran families Myrmeleontidae (antlions) and Ascalaphidae (owlflies) is presented, with a particular focus on their chromosome numbers and sex chromosome systems. Diploid male chromosome numbers are listed for 37 species, 21 genera from 9 subfamilies of the antlions as well as for seven species and five genera ...

متن کاملAggregations of Elementary Transformations
The techniques of aggregating transformations have been used in the development of blocked algorithms, in particular, the compact representations of aggregated Householder transformation have been wellknown. We show in this paper that the aggregation techniques can be integrated in a framework for aggregating general elementary transformations. The framework consists of three basic compact form...
متن کاملHierarchies of intensity preference aggregations
This paper deals with aggregation of fuzzy individual opinions into a single group opinion, based upon hierarchical intensity aggregation rules. Characterization theorems are given, and it is also shown that Montero's rationality and standard ethical conditions propagate under hierarchical aggregations.
متن کاملMechanics of fire ant aggregations.
Fire ants link their bodies to form aggregations; these can adopt a variety of structures, they can drip and spread, or withstand applied loads. Here, by using oscillatory rheology, we show that fire ant aggregations are viscoelastic. We find that, at the lowest ant densities probed and in the linear regime, the elastic and viscous moduli are essentially identical over the spanned frequency ran...
