Patients Improve, Patterns Persist: Longitudinal Stability of Rheumatoid Arthritis Joint Involvement Patterns

Arthritis Care &Research, EarlyView.
Objective Rheumatoid arthritis is a heterogeneous disease. Data‐driven approaches, from synovial histology to joint involvement patterns (JIPs), have sought to define clinically meaningful subgroups. Whether these subgroups represent stable phenotypes or transient disease states remains unclear.

Elastic–Plastic Modeling and Experimental Characterization of Granular Jamming Actuators

Advanced Engineering Materials, EarlyView.
Granular jamming enables rapid switching between soft and rigid mechanical states. Here, a reduced‐order elastic‐perfectly‐plastic beam framework captures pressure‐dependent loading, unloading, residual deformation, and hysteresis in jammed beams, while matching three‐point bending experiments across materials and geometries. The framework links design

Comment on Letter “On the excitation of the Earth's polar motion” [PDF]

Geophysical Research Letters, 1987
The use of modern global meteorological data in the investigation of the extent to which atmospheric processes contribute to the observed short‐term and other changes in polar motion (and length of the day) and the determination, by subtraction, of changes in the Earth's rotation of non‐meteorological origin was initiated several years ago.

Impact of the Process Atmosphere During Hot Isostatic Pressing on the Near‐Surface Composition of an Additively Manufactured Austenitic High‐Interstitial Steel

Advanced Engineering Materials, EarlyView.
A high interstital austenitic steel is additively manufactured and postdensified by HIP to eliminate gas porosity. Thereby, the loss of N and Mn in Ar HIP atmosphere is investigated. Further, HIP using N2 atmosphere is investigated which led to excessive nitride formation.

Regional Signals in Atmospheric and Oceanic Excitation of Polar Motion [PDF]

International Astronomical Union Colloquium, 2000
AbstractAtmospheric and oceanic variability have been shown to play a role in the excitation of polar motion. Regional patterns of atmospheric and oceanic excitation are analysed and compared. The equatorial excitation functions, χ1 an χ2, for the ocean are computed using velocity and mass fields from a near-global ocean model, driven by observed ...

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

Advanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Polar motions excited by a convecting viscous mantle

Geophysical Research Letters, 1992
The role played by time‐dependent mantle convection on exciting long‐term polar motions is examined by means of a viscous model. For sufficiently low effective viscosity, polar‐wander speeds of 0(1 deg/Myr) would require contributions from the off‐diagonal elements of the inertia tensor, with magnitudes around 105 times smaller than those found in ...
