A cross‐layer anti‐jamming method in satellite Internet
IET Communications, Volume 17, Issue 1, Page 121-133, January 2023., 2023 Abstract In view of the diverse jamming environment, the single‐level anti‐jamming method faces some challenges such as poor timeliness, high cost and poor effect. In this paper, routing delay, cost overhead and diversified jamming threats are comprehensively considered. In addition, a cross‐layer anti‐jamming method is proposed in the scenario of busy

Unraveling metachronal wave effects on heat and mass transfer in Non-Newtonian fluid
Case Studies in Thermal EngineeringNon-Newtonian fluids flow generated by “cilia” are critical in medicine and bio-medical engineering. Such investigations are created by the back-and-forth movement of a microscopic hair-like structure connected to the walls, which causes a metachronal ...

Limnology and Oceanography, EarlyView.Abstract Harmful algal blooms caused by toxin‐producing species of the diatom genus Pseudo‐nitzschia have been linked to anomalously warm ocean conditions in the Northern California Current System. This study compares summertime concentrations of Pseudo‐nitzschia spp.

Design, build, test and flight of the world's fastest electric aircraft
IET Electrical Systems in Transportation, Volume 12, Issue 4, Page 380-402, December 2022., 2022 Project ACCEL pushed the limits of energy management, thermal management, and mass saving, while maintaining measured safety for the pilot and crew to ultimately achieve world record‐breaking flights. The blank sheet design of the ESS and powertrain allowed for an appropriately optimised solution, swiftly moving into physical testing allowed for rapid ...

Bloom compression alongside marine heatwaves contemporary with the Oregon upwelling season
Limnology and Oceanography, EarlyView.Abstract Marine heatwave (MHW) events have led to acute decreases in primary production and phytoplankton biomass in the surface ocean, particularly at the mid latitudes. In the Northeast Pacific, these anomalous events have occasionally encroached onto the Oregon shelf during the ecologically important summer upwelling season.

Dynamics of Dissipative Cavity Solitons in a Lattice Trap
Laser &Photonics Reviews, EarlyView.This work presents a generalized analytical model elucidating the dynamics of dissipative solitons in dual‐frequency‐pumped Kerr‐nonlinear cavities. The unified framework predicts new phenomena and expounds hitherto unexplained experiments covering hysteresis, Arnold tongues, and existence region of all‐optical dissipative time crystals.

Summary of 1978 Southeastern Virginia Urban Plume study: Aircraft results for carbon monoxide, methane, nonmethane hydrocarbons, and ozone [PDF]
The characteristics of the Southeastern Virginia urban plume were defined with emphasis on the photon-oxidant species. The measurement area was a rectangle, approximately 150 km by 100 km centered around Cape Charles, Virginia.
