Electrohydraulic Folding Ring Actuators for Radial Contraction
Advanced Science, EarlyView.This work presents an Electrohydraulic Folding Ring Actuator that combines high‐performance electrohydraulic actuation with origami‐inspired folding geometry to achieve constricting radial actuation. This integration yields significant inner lumen constriction, alongside a gripping force capable of holding objects exceeding four times the actuator's ...

Volcanic effects on climate: revisiting the mechanisms [PDF]
Atmospheric Chemistry and Physics, 2007 The characteristics of planetary wave energy propagation are being compared based on NCEP reanalysis data from 1958 to 2002 between boreal winters after strong volcanic eruptions, non-volcanic winters and episodes of strong polar vortex lasting at least ...

Aspects of Planetary Wave Transports in the Middle Atmosphere [PDF]
, 1984 The heat and momentum flux due to standing planetary waves in the stratosphere were calculated on the basis of satellite data. The convergence of these fluxes was investigated and shows an apparent heating and acceleration of the mean zonal state.

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective
Advanced Electronic Materials, EarlyView.Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

A Model of Intra-seasonal Oscillations in the Earth atmosphere
, 2007 We suggest a way of rationalizing an intra-seasonal oscillations (IOs) of the Earth atmospheric flow as four meteorological relevant triads of interacting planetary waves, isolated from the system of all the rest planetary waves.

Observational and theoretical studies of the evolving structure of baroclinic waves [PDF]
, 1984 Dynamical processes involved in comma cloud formation, and passive tracer evolution in a baroclinic wave are discussed. An analytical solution was obtained demonstrating the complex nongeostrophic flow pattern involved in the redistribution of low level ...
