Type II InP/GaAsSb transistors have attracted much interest in high speed microelectronics. However, Kirk-effectinduced current blocking was observed, limiting the highest achievable current density and hence the speed. In this work, we present an explanation as to the cause of current blocking in InP/GaAsSb DHBTs. The effects of collector thickness are investigated and methods to achieve highe...

The effect of spring temperature on spring phenology is well understood in a wide range of taxa. However, studies on how winter conditions may affect spring phenology are underrepresented. Previous work on Anthocharis cardamines (orange tip butterfly) has shown population-specific reaction norms of spring development in relation to spring temperature and a speeding up of post-winter development...

In this study, chromosome numbers of five Cardamine taxa [C. bulbifera Crantz, C. impatiens var. pectinata (Pall. ex DC.) Trautv., lazica Boiss. & Bal., tenera Gmel Mey. and graeca L.] from Turkey have been informed for the first time. The were determined as 2n=4x=24 in bulbifera, 2n=2x=16 tenera, 2n=2x=14 lazica, 2n=2x=12 graeca. Also, was different others with having satellite. Chromosomes st...

Timing of plant development both determines the abiotic conditions that the plant experiences and strongly influences the intensity of interactions with other organisms. Plants and herbivores differ in their response to environmental cues, and spatial and temporal variation in environmental conditions might influence the synchrony between host plants and herbivores, and the intensity of their i...
