Prompt emission of gamma-ray bursts (GRBs) is likely generated at early stages of the ejecta expansion, possibly by internal shocks. The γ-ray front overtakes the ejecta and sweeps the ambient medium. As a result a gap is opened between the ejecta and the medium that surfs the front ahead. Effectively, the ejecta move in a cavity until they reach a radius Rgap ≈ 3 × 1015E 53 cm where E is the i...

Wheat gene Yr39 confers durable high-temperature adult-plant (HTAP) resistance to stripe rust caused by Puccinia striiformis f. sp. tritici, one of the most destructive diseases wheat worldwide. The objective this study was transfer into four Chinese elite cultivars. Backcross inbred line populations were developed from cultivars Chuanmai 42 (CM42), Bainong Aikang 58 (AK58), Han 6172 (H6172) an...

We report InP/In0.53Ga0.47As/InP double heterojunction bipolar transistors (DHBTs) demonstrating simultaneous 460 GHz f and 850 GHz fmax. The devices were fabricated using a triple mesa process with dry-etched, refractory metals for emitter contact formation. The devices incorporate a 35 nm thick InP emitter which enables a wet etch emitter process demonstrating 220 nm wide emitter-base juncti...
