Magnetic Bioprinting and Actuation of Stretchable Muscle Tissue

Advanced Healthcare Materials, EarlyView.
Human and murine myoblasts labeled with iron oxide nanoparticles are magnetically bioprinted into wrench‐shaped tissues, which are then anchored between two magnetic needles. Mechanical stretching of these tissues enhances both their maturation and functional performance. Abstract Engineering tissues with precise, long‐lasting shapes and the capability

Influence of CO₂ observations on the optimized CO₂ flux in an ensemble Kalman filter [PDF]

Atmospheric Chemistry and Physics, 2014
In this study, the effect of CO2 observations on an analysis of surface CO2 flux was calculated using an influence matrix in the CarbonTracker, which is an inverse modeling system for estimating surface CO2 flux based on an ensemble Kalman filter.

Improved Estimation of O-B Bias and Standard Deviation by an RFI Restoration Method for AMSR-2 C-Band Observations over North America

Remote Sensing, 2022
Spaceborne microwave radiometer observations play vital roles in surface parameter retrievals and data assimilation, but widespread radio-frequency interference (RFI) signals in the C-band channel result in a lack of valuable data over large areas ...

A Practical Method to Estimate Information Content in the Context of 4D-Var Data Assimilation. I: Methodology [PDF]

, 2011
Data assimilation obtains improved estimates of the state of a physical system by combining imperfect model results with sparse and noisy observations of reality. Not all observations used in data assimilation are equally valuable.

Consistent assimilation of multiple data streams in a carbon cycle data assimilation system [PDF]

Geoscientific Model Development, 2016
Abstract. Data assimilation methods provide a rigorous statistical framework for constraining parametric uncertainty in land surface models (LSMs), which in turn helps to improve their predictive capability and to identify areas in which the representation of physical processes is inadequate.

Dynamics and predictability of secondary eyewall formation in sheared tropical cyclones

Journal of Advances in Modeling Earth Systems, 2017
This study examines the predictability and dynamics of tropical cyclone (TC) secondary eyewall formation (SEF), eyewall replacement cycles (ERC), and intensity changes under moderate environmental shear through convection‐permitting ensemble simulations.

Designing Physical Unclonable Functions From Optically Active Materials

Advanced Materials, EarlyView.
Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.
