Seagrass radiation after Messinian salinity crisis reflected by strong genetic structuring and out-of-Africa scenario (Ruppiaceae). [PDF]
PLoS ONE, 2014 Many aquatic plant and seagrass species are widespread and the origin of their continent-wide ranges might result from high gene flow levels. The response of species when extending northwards since the Last Glacial Maximum can be opposed to the ...

Influence of inherent parameter of stabilized UHF oscillators on autodyne response formation at a strong reflected signal [PDF]
Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2011 Results of an autodyne response analysis in UHF oscillators stabilized by the external high-Q cavity in the case of the strong signal when the reflected wave amplitude commen-surable with the own oscillation amplitude.

Strong Solar Radiation Forces from Anomalously Reflecting Metasurfaces for Solar Sail Attitude Control [PDF]
Scientific Reports, 2018 AbstractWe examine the theoretical implications of incorporating metasurfaces on solar sails, and the effect they can have on the forces applied to the sail. This would enable a significant enhancement over state-of-the- art attitude control by demonstrating a novel, propellant-free and low-mass approach to induce a roll torque on the sail, which is a ...

Mapping potential surface contributions to reflected solar radiation
Environmental Research Communications, 2022 Modifying Earth’s albedo is one of the strategies considered to reduce its energy imbalance and slow global warming by reflecting solar energy. Atmospheric contributions to reflected solar radiation through stratospheric aerosols or cloud brightening ...

Numerical calculation of strong-field laser-atom interaction: An approach with perfect reflection-free radiation boundary conditions [PDF]
Laser Physics, 2010 The time-dependent, single-particle Schrodinger equation with a finite-range potential is solved numerically on a three-dimensional spherical domain. In order to correctly account for outgoing waves, perfect reflection-free radiation boundary conditions are used on the surface of a sphere.

Ground thermal regimes and implications for permafrost distribution on Kilimanjaro, Tanzania
Arctic, Antarctic, and Alpine Research, 2021 Tropical mountain permafrost has a unique thermal regime due to ground surface exposure to strong solar radiation. The intensity of the surface offset resulting from snow cover also strongly affects the absence or presence of permafrost.
