An analytical model for wind-driven Arctic summer sea ice drift [PDF]
The Cryosphere, 2016 The authors present an analytical model for wind-driven free drift of sea ice that allows for an arbitrary mixture of ice and open water. The model includes an ice–ocean boundary layer with an Ekman spiral, forced by transfers of wind-input ...

Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells
Advanced Materials, EarlyView.This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...

The flight of the tethered satellite system
Eos, Transactions American Geophysical Union, 1992 The first Tethered Satellite System (TSS‐1) Electrodynamics Mission is scheduled for launch aboard the space shuttle ST‐46 on July 31, 1992, as a joint mission between the United States and Italy. A 500‐kg, 1.6‐m‐diameter satellite, attached to the shuttle by a thin (.24 cm), conducting, insulated wire (tether), will be reeled upwards from the orbiter ...

Tethered Satellite System Stability [PDF]
, 1989 Abstract : Issues of stability of the Tethered Satellite System (TSS) during station-keeping, de- ployment and retrieval are considered. The basic nonlinear equations of motion of the TSS are derived using the system Lagrangian. Using the Hopf bifurcation theorem, tension control laws are established which guarantee the stability of the system during ...
