Advanced Optical Materials, EarlyView.An ultrathin Sr interlayer is introduced as a charge‐generation assist layer to overcome the electron‐injection barrier in deep‐LUMO charge‐generation layers (CGLs) of tandem OLEDs. The Sr layer facilitates trap‐assisted tunneling and lowers the effective injection barrier, enabling improved charge balance and yielding tandem OLEDs with doubled ...

Observing FRB 121102 with VERITAS; Searching for Associated TeV Emission
, 2017 Fast radio bursts are bright, unresolved and short flashes of radio emission originating from outside the Milky Way. The origin of these mysterious outbursts is unknown, but their high luminosity and short duration has prompted much speculation.

Spermatogenesis, 2014 Current knowledge on avian spermiogenesis, including strengths and weaknesses, has been reviewed. Information on avian spermiogenesis considerably lags behind that in mammals because of the paucity of reports in birds. Spermiogenesis in passerine birds has received even much less attention than in non-passerine birds.

Information Transmission Strategies for Self‐Organized Robotic Aggregation
Advanced Robotics Research, EarlyView.In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures
Advanced Robotics Research, EarlyView.Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.
