Eroding Confidence in Gully Location Risk Prediction in Mine Pit Rehabilitation

Land Degradation &Development, EarlyView.
ABSTRACT Understanding how rehabilitation measures, such as landform shaping, and surface finishes impact gully erosion risk could assist in designing less erosive rehabilitation. In this study we use high resolution digital elevation models of rehabilitated mine pits to explore risk factors for gully formation.

Real‐Time Observation of Soliton Buildup and Self‐Organization in a GHz Harmonic Mode Locked Fiber Laser

Laser &Photonics Reviews, EarlyView.
This image is an experimental recording of the buildup of harmonic mode‐locking in a fiber laser. The horizontal dimension corresponds to one cavity round trip, where the laser field intensity is displayed in a color scale. The vertical dimension is the evolution time in logarithmic scale, spanning from microseconds to seconds.

Evidence of White Matter R2* Homogenization After Formalin Fixation

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Disentangling intrinsic susceptibility‐driven R2* characteristics in white matter (WM) from fixation‐related effects using in vivo, postmortem (PM) in situ, and formalin‐fixed PM ex situ MRI. Methods DTI and multi‐echo gradient‐echo MRI were acquired in vivo, PM in situ and PM ex situ.

Time‐Resolved 3D Imaging and Strain Analysis of the Skeletal Muscle

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and validate a method for time‐resolved 3D imaging and strain analysis that enables quantification of dynamic in vivo muscle deformations from aperiodic continuous motion. Theory and Methods Controlled deformations were induced in the thigh muscles of eight healthy volunteers using a pneumatic pressure cuff, both under ...

A Physics‐Informed Koopman Operator Framework for Decentralized Discrete‐Time Sequential Control of a Modular Aerial Parcel Delivery Robot

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This paper presents a Physics‐Informed Koopman Operator (PIKO) framework integrated with a discrete‐time Sequential Action Control (SAC) for real‐time, decentralized control of a modular aerial parcel delivery robot composed of multiple independently actuated propeller modules.
