Anticipation of the landing shock phenomenon in flight simulation [PDF]
An aircraft landing may be described as a controlled crash because a runway surface is intercepted. In a simulation model the transition from aerodynamic flight to weight on wheels involves a single computational cycle during which stiff differential ...

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 1, January 2026.Employing an orientation induction and rapid deposition strategy, the oriented growth of ZnO piezoelectric films is effectively regulated, resulting in significantly enhanced piezoelectric polarization and electromechanical response. The ZnO OIL sensor exhibits excellent sensitivity, fast response, and high measurement accuracy in practical ...

Journal of Engineering Education, Volume 115, Issue 1, January 2026.Abstract Background Ethics and diversity, equity, and inclusion (DEI) are critical aspects of engineering, and connections between ethics/DEI are becoming increasingly common place in engineering education and practice. For example, many engineering professional organizations have integrated DEI into their codes of ethics.

Extreme wildfire conditions shift coastal phytoplankton community structure in California
Limnology and Oceanography, Volume 71, Issue 1, January 2026.Abstract Extreme wildfires have increased in frequency and intensity globally, particularly in the Western United States. Here we examine how the 2020 Lightning Complex Fires in California influenced coastal phytoplankton communities using monitoring network data products in the Monterey Bay, the ocean region closest to this large fire.

Morphology of Antarctic Polygons and Implications for Polygon Evolution and Subsurface Ice Dynamics
Permafrost and Periglacial Processes, Volume 37, Issue 1, Page 143-153, January/March 2026.ABSTRACT Polygonal terrain results from thermal contraction, is commonly found in periglacial environments, and serves as a valuable proxy for interpreting subsurface ice distribution and climate history on Earth and Mars. In this study, we investigate the morphology of polygons in Beacon Valley, Antarctica, to assess the relationship between polygon ...

System for indicating direction of intruder aircraft [PDF]
, 1973 A pilot warning indicator system consisting of a flashing beacon, a detector, and an indicating panel is described. The detector responds to radiant energy from another aircraft's beacon by energizing particular signal lamps positioned in the periphery ...

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.Abstract Martian carbonate‐bearing rocks are compelling targets for exploration because they preserve detailed records of past aqueous processes, climate, and habitability. The Margin unit in Jezero crater is a distinct olivine‐ and carbonate‐bearing unit stratigraphically underlying the western fan, lining the inner margin of the western crater rim ...
