Inactivation of the Neurospora crassa Gene Encoding the Mitochondrial Protein Import Receptor MOM19 by the Technique of ''Sheltered RIP'' [PDF]

, 1994
We have used a technique referred to as ``sheltered RIP'' (repeat induced point mutation) to create mutants of the mom-19 gene of Neurospora crassa, which encodes an import receptor for nuclear encoded mitochondrial precursor proteins.

Elimination of Necking and Aspect Ratio Dependence in Uniaxial Actuators by Continuous Fiber Reinforcement

Advanced Robotics Research, EarlyView.
A novel carbon fiber reinforcement for dielectric elastomer actuators enhances actuation force while decoupling electromechanical performance from the actuator's aspect ratio. Unlike conventional fiber reinforcements, it enables a uniform planar stretch state along the entire actuator.

A Prediction Method for LEO Satellite Channels Under Channel Aging

IEEE Access
To address channel state information (CSI) aging in low-Earth-orbit (LEO) links caused by propagation delay and platform/user mobility, we study CSI prediction with carrier-to-noise ratio ( $C/N_{0}$ ) as the target.

Storm-driven changes in rip channel patterns on an embayed beach

, 2010
This paper introduces a semi-automatic computer algorithm designed to detect rip current channels in video imagery. As a case study, this method is applied to 3.3 years of video data from an embayed beach to demonstrate the link between antecedent surf ...

A Proof‐of‐Concept Assessment of a Novel Wearable Eyelid Muscle Device: A Pre‐Clinical Animal Cadaver Study for Eyelid Closure Restoration

Advanced Robotics Research, EarlyView.
This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.

The Roles of Bathymetry and Waves in Rip-Channel Dynamics

The behavior and predictability of rip currents (strong, wave-driven offshore-directed surfzone currents) have been studied for decades. However, few studies have examined the effects of rip channel morphology on the rip generation or have compared ...

Wave-current interaction in formation of rip channel system [PDF]

, 2013
Current effect on waves (CEW) is examined for formation of a rip channel system with a barotropic modeling framework based on Uchiyama et al. (2009). The model consists of an Eulerian phase-averaged shallow water equation with a vortex-force formalism ...
