Effects of acute high‐altitude exposure on working memory: A functional near‐infrared spectroscopy study

open access: yesBrain and Behavior, Volume 12, Issue 12, December 2022., 2022
The current study adopted an experimental paradigm of digital span to evaluate acute high‐altitude exposure impairment on working memory. The subjects showed obvious physiological adaptation mechanism at acute altitude. The results of hemodynamic response confirmed the important role of left DLPFC in the process of working memory, revealed abnormal ...

Accurate Terrain Estimation for Humanoid Robot Based on Disturbance State Observer

open access: yesIEEE Access, 2021
This study proposes a novel reactive terrain estimation system for humanoid robots from the perspective of a state observer. The design process is as follows: the underfoot force disturbance is converted into an underfoot position disturbance by using an

Statistical evaluation of proxies for estimating the rainfall erosivity factor

open access: yesScientific Reports, 2022
Considering the high-temporal-resolution rainfall data requirements for calculating the Rainfall Erosivity factor (that is, the R-factor), studies have developed a large number of proxies for the R-factor (PR).

Formation of an Intracontinental Orogen Above the Permo-Triassic Mantle Convection Cell in the Paleo-Tethys Tectonic Realm due to Far-Field Stress Derived From Continental Margins

open access: yesFrontiers in Earth Science, 2022
The identification of intraplate orogens seemingly poses challenges to the plate tectonic theory. Delineating the formation processes of intraplate orogens can provide clues for the better understandings of the above issue.

Statistical determination of rainfall-runoff erosivity indices for single storms in the Chinese Loess Plateau.

open access: yesPLoS ONE, 2015
Correlation analysis is popular in erosion- or earth-related studies, however, few studies compare correlations on a basis of statistical testing, which should be conducted to determine the statistical significance of the observed sample difference. This
