Weakly Convex Ridge Regularization for 3D Non‐Cartesian MRI Reconstruction

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose While highly accelerated non‐Cartesian acquisition protocols significantly reduce scan time, they often entail long reconstruction delays for 3D data. Deep learning–based reconstruction methods can alleviate this, but typically rely on complex, highly parametrized architectures.

Finite‐Difference Reduced Transfer Matrix Method for Multibody Systems With Rotating Beams

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Multibody systems with rotating beams serve as critical simplified models of core components in engineering systems; however, existing analytical and numerical methods have limitations in analyzing their complex dynamic behavior. This paper proposes the Finite‐Difference Reduced Multibody System Transfer Matrix Method (FD‐RMSTMM), which ...

Hydro‐Mechanical Modelling of Gas Migration in Bentonite: Formulation and Laboratory‐Scale Validation

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Gas generation and migration in bentonite buffer materials are critical processes affecting the performance of deep geological repositories for radioactive waste. This study presents a new hydro‐mechanical formulation for simulating gas migration in saturated, compacted bentonite, with particular emphasis on the role of non‐uniform stress ...

Novel Modeling Approach for Arc Routing Problems

open access: yesNetworks, EarlyView.
ABSTRACT This paper introduces a novel modeling approach for arc routing problems (ARPs) which is easily applied to multiple ARP variants (e.g., capacitated ARPs, multiple depot ARPs, heterogeneous fleets). Our approach tracks the order in which arcs are serviced, rather than explicitly tracking deadheading, and couples the sequence of serviced arcs to

Coupled diabatic and frictional forcing of single‐layer vortical flow

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
A single‐layer balanced model is used to illustrate how diabatic and frictional forcing of a primary balanced vortical flow can be coupled self‐consistently, including the advection of potential vorticity by the induced transverse circulation. The coupling is illustrated in the context of a developing tropical cyclone, in which boundary‐layer dynamics ...
