Abstract Hycean worlds are a proposed subset of sub-Neptune exoplanets with substantial water inventories, liquid surface oceans, and extended hydrogen-dominated atmospheres favorable for habitability. We aim to quantitatively define the inner edge habitable zone (HZ) using 1D radiative-convective model. As limiting case, we model dry hydrogen–helium envelope above ocean. For 1 bar (10,100 bar)...

We present the detection of the signatures of land use/land cover (LULC) changes on the regional climate of the US High Plains. We used the normalized difference vegetation index (NDVI) as a proxy of LULC changes and atmospheric CO2 concentrations as a proxy of greenhouse gases. An enhanced signal processing procedure was developed to detect the signatures of LULC changes by integrating autoreg...

An experiment was conducted in order to reconstruct previous timbre recognition experiments, measure the effect of ensemble experience and short-term training on the recognition rate, and generate more detailed baseline data to help evaluate the performance of timbre recognition computer models. The subjects, who were conservatory students, had to identify between 2, 3, 9, and 27 instruments on...
