Libby–Fox perturbations and the semi-analytic adjoint solution for laminar viscous flow along a flat plate

The properties of the solution to the adjoint two-dimensional boundary layer equations on a flat plate are investigated from the viewpoint of Libby–Fox theory, which describes the algebraic perturbations to the Blasius boundary layer. The adjoint solution is obtained from the Gre...

On the origin of the twilight color index maximum and its application to cloud-height retrieval

A number of previous studies have demonstrated the capability of detecting high-altitude clouds during twilight using the color index (CI), defined as the ratio of zenith intensities at two different wavelengths, typically selected in the visible range or near infrared (NIR). Whe...

Adaptive thermogenesis and fermentation as survival strategies of vegetative cells of Bacillus subtilis under simulated Martian stressors

<title>Abstract</title> Microbial responses to Mars‑analog environments are key to understanding the limits of life and improving life‑detection strategies. Here, we investigated the survival and physiological adaptation of <italic>Bacillus subtilis</italic> exposed for five sols...

Synthesis of mineral-organic hybrid materials under dynamic prebiotic conditions

Abstract The increasing of molecular complexity must be understood as a planetary phenomenon where prebiotic chemistry and geological settings converge. In this scene, HCN chemistry may have played a crucial role. In this study, we demonstrate that alkaline water aerosols, cyanid...
