Enhancing Aircraft Fuel Burn Modeling on the Airport Surface

, 2018
Aircraft fuel burn modeling is useful for a range of systems analysis activities. Models such as the FAA’s Aviation Environmental Design Tool (AEDT) are widely used to support these activities. Previously, limited availability to thrust and movement data

Microglial TSPAN4‐Dependent Migrasomes Promote Pathological Retinal Neovascularization via Immune‐Vascular Crosstalk

Advanced Science, EarlyView.
Combined high‐glucose and hypoxic stress switches microglia into a TSPAN4‐dependent migrasome‐producing state. These migrasomes deliver pro‐angiogenic signals to endothelial cells, activating HIF‐1α/VEGF signaling, disrupting vascular junctions, and fueling pathological neovascularization. This work uncovers migrasome‐mediated immune‐vascular crosstalk

Impact of nuclear data uncertainty on safety calculations for spent nuclear fuel geological disposal

EPJ Web of Conferences, 2017
In the design of a spent nuclear fuel disposal system, one necessary condition is to show that the configuration remains subcritical at time of emplacement but also during long periods covering up to 1,000,000 years.

Aryl‐Tethered Pendant Sterically Shielded Imidazoliums for Durable Anion Exchange Membranes

Advanced Science, EarlyView.
An aryl‐tethered, sterically shielded imidazolium architecture protects cationic sites from hydroxide attack while avoiding vulnerable benzylic cation–polymer linkages. Incorporated into poly(arylimidazolium) membranes, this dual‐protection design enhances alkaline and oxidative durability and supports prolonged alkaline water electrolysis, offering a ...
