Looking at Soil as It Is: Evolution of Microscopic Soil Characterization From Kubiëna to Artificial Intelligence

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
We provide a historic overview of microscopic soil structure characterization from its founding father, Walter Kubiëna, to several technical revolutions like automation, digitalization, and artificial intelligence. In addition to technical advancements, we explore how concepts and research questions have evolved in time.

Where opportunity meets desire: Predicting antlerless deer harvest selectivity during Wisconsin's nine‐day firearm season

open access: yesThe Journal of Wildlife Management, EarlyView.
We predicted Wisconsin deer hunters’ likelihood to take an available antlerless deer harvest opportunity on a given day of the 9‐day firearm season using a combination of personal characteristics of the hunter and situational factors of the hunting day.

Association between walking gait biomechanical changes after anterior cruciate ligament injury or reconstruction and the development of osteoarthritis: A systematic review

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Anterior cruciate ligament (ACL) injury and reconstruction significantly increase the risk of knee osteoarthritis (OA). Biomechanical alterations during walking are frequently suggested contributors to OA development. This systematic review aims to determine the association between walking gait biomechanical changes following ACL ...

Fixed-time control for automatic carrier landing with disturbance

Aerospace Science and Technology, 2021
Abstract This paper addresses the fixed-time control problem for automatic carrier landing. By transforming a six-degrees-of-freedom fixed-wing aircraft model into the affine form with angle of attack controlled by thrust independently, backstepping technique is able to be adopted as the main control frame.

Adaptive Super-Twisting Control for Automatic Carrier Landing of Aircraft

IEEE Transactions on Aerospace and Electronic Systems, 2020
This paper studies the carrier landing control problem for aircraft in presence of model uncertainty, deck motion, and airwake disturbances. An automatic carrier landing system (ACLS) is designed. An adaptive super-twisting control (ASTC) scheme is proposed for a class of nonlinear multivariable system by combining parameter adaptions and sliding mode ...
