Advanced Functional Materials, EarlyView.Establishment of bidirectional communication behavior between natural and artificial cells. The first type of communication from natural dendritic cells to artificial polymeric cells was achieved via ATP release after cell lysis. The released ATP was taken up via gated UV‐controlled permeability increase of the polymeric membrane for performing ...

Velocity Profiles at the Swash Zone
Coastal Structures 2003, 2004Velocity profiles at the swash zone have been sampled with an ADVP during a large scale experiment on a fixed bed beach. The unique set of data permits to observe the time variation of the velocity distributions and to contribute to the debate concerning the variation of the friction factor, f , in a swash cycle. The analyses of the velocity data with

The limit profile of a rapid movement velocity
Human Movement Science, 2010In motor control, various theories and computational models have been developed to explain and model the stereotypical velocity profiles of skilled rapid movements. According to the fact that these theories aim at describing the same physical pattern (a velocity profile) with different mathematical expressions, some relationships between these various ...

THE GENERATION OF VELOCITY PROFILES WITH AN ARTIFICIAL SIMULATOR
International Journal of Pattern Recognition and Artificial Intelligence, 2004A few years ago, a Kinematic Theory was proposed to analyze rapid human movements. The theory is based on a delta-lognormal equation which can be used to globally describe the basic properties of velocity profiles using seven parameters. This realistic model has been of great use to solve pattern recognition problems (signature verification ...

Underwater localization with sound velocity profile
Proceedings of the Thirteenth ACM International Conference on Underwater Networks & Systems, 2018Underwater acoustic sensor networks (UASNs) is a widely used enabling technique for various underwater applications. To facilitate these real applications, it is essential to obtain the position information of sensor nodes by localization methods. One of the most common localization approaches employs time-of-arrival (TOA) to measure and utilize the ...

The Reliability of Individualized Load–Velocity Profiles
International Journal of Sports Physiology and Performance, 2018Purpose: To examine the reliability of peak velocity (PV), mean propulsive velocity (MPV), and mean velocity (MV) in the development of load–velocity profiles (LVP) in the full-depth free-weight back squat performed with maximal concentric effort. Methods: Eighteen resistance-trained men performed a baseline 1-repetition maximum (1-RM) back-squat trial

In vivo measurement of velocity profiles in arterioles
Bulletin of Experimental Biology and Medicine, 2006Measurements of velocity profiles in arterial microvessels (20-103 mu in diameter) of rat mesentery and m. creamaster showed that bloodflow regimen under natural conditions can be similar to that of Newton fluid or pseudoplastic laminar stream, which indicates significant fluctuations in blood viscosity.

The urban wind velocity profile
Atmospheric Environment (1967), 1971Abstract An experimeatal method and analytical procedures which allow a captive balloon to be used as an instrument support for wind and other meteorological measurements above an urban area have been developed, and their use to make measurements of the average wind speed and temperature at heights up to 1000 ft at two urban sites is described.

Velocity Profile of Human Horizontal Saccades
Ophthalmologica, 2010To assess saccadic trajectories, we evaluated the velocity profile using the ‘skewness ratio’ (the proportion of acceleration time to total saccadic duration) as a parameter. Horizontal cross-center saccades against target movements of 10°, 20° and 30° were measured in 6 normal subjects using the magnetic search coil method.

Magnetic resonance velocity mapping of normal transtricuspid velocity profiles
The International Journal of Cardiac Imaging, 1997To investigate the velocity profiles of transtricuspid inflow, we examined 20 normal subjects (17 males and 3 females, mean age 27 +/- 7) by the magnetic resonance imaging (MRI). Electrocardiographic gating was performed in all anatomical and flow studies, and sequences were triggered by the R wave.
