Air Corridors: Concept, Design, Simulation, and Rules of Engagement

Description: Article presenting fundamental insights into the design of air corridors with high operational efficiency as well as zero collisions. It begins with the definitions of air cube, skylane or track, intersection, vertiport, gate, and air corridor. Then a multi-layered air corridor model is proposed. Traffic at intersections is analyzed in detail with examples of vehicles turning in different directions. The concept of capacity of an air corridor is introduced along with the nature of distribution … more

A consensus statement on detection of hippocampal sharp wave ripples and differentiation from other fast oscillations

Description: Article suggests that common standards for recording, detection, and reporting for intracranial recordings in humans that suggest their role in episodic and semantic memory does not exist. Authors of the article outline the methodological challenges involved in detecting ripple events and offer practical recommendations to improve separation from other high-frequency oscillations, and argue that shared experimental, detection, and reporting standards will provide a solid foundation for future t… more

On the evolving nature of c/a ratio in a hexagonal close-packed epsilon martensite phase in transformative high entropy alloys

Description: Article studying c/a ratio and transformation volume change of h.c.p. (hexagonal close packed) epsilon martensite phase in transformative high entropy alloys (HEAs) quantified as functions of alloy chemistry, friction stir processing and tensile deformation. The study reveals that while intrinsic c/a is dependent on alloying elements, c/a of epsilon in transformative HEAs changes with processing and deformation.
