RISAvian hybrids: incidence and geographic distribution of hybridisation in birds
The identification of hybrids between closely related taxa bears relevance for studies of gene flow and the evolution of mechanisms of genetic isolation. As such it is an important phenomenon when studying speciation. Furthermore, hybridisation...
Hybridization between sister taxa versus non-sister taxa: a case study in birds
Capsule Sister taxa hybridize more frequently than non-sister taxa.
Aims To test whether the frequency of hybridization is higher in avian sister species than in non-sister
species, based on molecular phylogenetic relationships...
Broadside Coupler Channels 1 To 10 GHz
quadrature hybrid couplers are useful in communications systems and measurement applications. Many
3-dB, 90-deg. hybrid directional couplers have been developed for narrowband use but, with growing interest in ultrawideband (UWB...
Bayes Estimations of the Unified Hybrid Censored Weibull Distribution
Unified hybrid censoring is a mixture . . ....
Potential zones for hybridization between black-headed and Red-head buntings in the palearctic region
Black-headed (Emberiza melanocephala) and Red-headed (Emberiza
bruniceps) buntings known to hybridize southeast of Caspian Sea.
Two species also come to close in northern Caspian Sea and eastern
Westward expansion in breeding range of Red-headed Bunting (Emberiza bruniceps) in northern Iran
Range size and distribution of species can be greatly influenced by a
wide range of ecological, behavioral, and historical process such as
competitive interactions between two species in hybrid zone. Black-headed (Emberiza...
Synthesis ad identification of a novel organic-inorganic hybrid constructed from isopolyanion nd aminoacid (phenylalanine)

Hybrid Control of DC–DC Series Resonant Converters: The Direct Piecewise Affine Approach
new hybrid controller is presented
that is applicable to dc–dc series resonant converters and use neither r averaging nor small signal approximation. The dc–dc resonant converters are inherently switched affine systems with constrained...
