Slow Dynamics in Ion-Conducting Sodium Silicate Melts: Simulation and Mode-Coupling Theory

open access: yes, 2005
A combination of molecular-dynamics (MD) computer simulation and mode-coupling theory (MCT) is used to elucidate the structure-dynamics relation in sodium-silicate melts (NSx) of varying sodium concentration.

Modeling and Characterization of a Self‐Sensing Soft Hydraulic Muscle

open access: yesAdvanced Intelligent Systems, EarlyView.
This article presents the self‐sensing soft hydraulic muscle (SSHM), a novel soft actuator capable of simultaneously sensing force and length without external sensors. A comprehensive model accurately predicts SSHM behavior, validated experimentally with minimal errors. Using propylene glycol enhances durability and reduces hysteresis.

Reorientational relaxation of a linear probe molecule in a simple glassy liquid

open access: yes, 1999
Within the mode-coupling theory (MCT) for the evolution of structural relaxation in glass-forming liquids, correlation functions and susceptibility spectra are calculated characterizing the rotational dynamics of a top-down symmetric dumbbell molecule ...

Diagnostic Odyssey of Atypical Long‐Chain 3‐Hydroxyacyl‐CoA Dehydrogenase Deficiency (LCHADD) Explained by Three Allelic Products From Two Pathogenic Variants

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Long‐chain 3‐hydroxyacyl‐CoA dehydrogenase deficiency (LCHADD) is an autosomal recessive mitochondrial defect of long‐chain fatty acid β‐oxidation, caused by biallelic pathogenic variants in HADHA or HADHB. We report a 22‐year‐old male with an atypically mild presentation of LCHADD who was referred to the Undiagnosed Diseases Network (UDN ...

The evolution of vibrational excitations in glassy systems

open access: yes, 1999
The equations of the mode-coupling theory (MCT) for ideal liquid-glass transitions are used for a discussion of the evolution of the density-fluctuation spectra of glass-forming systems for frequencies within the dynamical window between the band of high-

Temporal Modeling of Amyloid and Tau Trajectories in Alzheimer's Disease Using PET and Plasma Biomarkers

open access: yesAnnals of Neurology, EarlyView.
Objective This study aimed to compare positron emission tomography (PET) and plasma‐based temporal modeling of amyloid and tau biomarkers in Alzheimer's disease. Methods Longitudinal amyloid PET (n = 1,097, mean age ± SD = 72.5 ± 7.38 year, 51.4% male), 18F‐flortaucipir tau‐PET (n = 230, 74.3 ± 7.18 year, 52.2% female), and Fujirebio Lumipulse plasma p‐

Cooperativity Beyond Caging: Generalized Mode Coupling Theory

open access: yes, 2006
The validity of mode coupling theory (MCT) is restricted by an uncontrolled factorization approximation of density correlations. The factorization can be delayed and ultimately avoided, however, by explicitly including higher order correlations.

Functional models from limited data: A parametric and multimodal approach to anatomy and 3D kinematics of feeding in basking sharks (Cetorhinus maximus)

open access: yesThe Anatomical Record, EarlyView.
Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.

On the Bauschinger effect in supercoooled melts under shear: results from mode coupling theory and molecular dynamics simulations

open access: yes, 2012
We study the nonlinear rheology of a glass-forming binary mixture under the reversal of shear flow using molecular dynamics simulations and a schematic model of the mode-coupling theory of the glass transition (MCT).
