World Water Day: Citizen scientists provide valuable information on intermittent rivers（图）
World Water Day Citizen scientists valuable information intermittent rivers
2019/11/22
On World Water Day and throughout the year, citizen scientists are providing valuable data on intermittently dry rivers in the Southwest United States.Trained citizen scientists are mapping three such...
Vitamin C–enriched gelatin supplementation before intermittent activity augments collagen synthesis
bone exercise ligament tendon inury prevention return to play
2018/11/12
Background: Musculoskeletal injuries are the most common complaint in active populations. More than 50% of all injuries in sports can be classified as sprains, strains, ruptures, or breaks of musculos...
Numerical Simulation of Nano Scanning in Intermittent-Contact Mode AFM under Q control
Numerical Simulation Nano Intermittent-Contact Mode AFM Q control Atomic Physics
2012/4/24
We investigate nano scanning in tapping mode atomic force microscopy (AFM) under quality (Q) control via numerical simulations performed in SIMULINK. We focus on the simulation of whole scan process r...
Detecting the temporal structure of intermittent phase locking
Detecting temporal structure intermittent phase locking
2011/7/7
This study explores a method to characterize temporal structure of intermittent phase locking in oscillatory systems. When an oscillatory system is in a weakly synchronized regime away from a synchron...
Spectral degeneracy and escape dynamics for intermittent maps with a hole
Escape rate Pomeau-Manneville maps Perron-Frobenius operators
2011/1/20
We study intermittent maps from the point of view of metastability. Small neighbourhoods of an intermittent fixed point and their complements form pairs of almost-invariant sets.
Intermittent activity of radio sources. Accretion instabilities and jet precession
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/4
We consider the radiation pressure instability operating on short timescales 10^3 - 10^6 years in the accretion disk around a supermassive black hole as the origin of the intermittent activity of radi...
Structure function measurements of the intermittent MHD turbulent cascade
Structure function measurements intermittent MHD turbulent cascade
2009/11/13
The intertmittent nature of turbulence within solar wind plasma has been demonstrated by several studies of spacecraft data. Using magnetic field data taken in high speed flows at high heliographic la...
Intermittent chaos driven by nonlinear Alfvén waves
Intermittent chaos nonlinear Alfvén waves
2009/11/11
We investigate the relevance of chaotic saddles and unstable periodic orbits at the onset of intermittent chaos in the phase dynamics of nonlinear Alfvén waves by using the Kuramoto-Sivashinsky (KS) e...
Radial evolution of intermittent heat flux in solar coronal holes
Radial evolution intermittent heat flux solar coronal holes
2009/11/11
Recently, we suggested that the source of ion heating in solar coronal holes is small-scale reconnection events (microflares) at the coronal base. The microflares launch intermittent heat flux up into...
Intermittent heating of the solar corona by MHD turbulence
Intermittent heating solar corona MHD turbulence
2009/11/3
As the dissipation mechanisms considered for the heating of the solar corona would be sufficiently efficient only in the presence of small scales, turbulence is thought to be a key player in the coron...
Asymmetric multifractal model for solar wind intermittent turbulence
Asymmetric multifractal model solar wind intermittent turbulence
2009/11/2
We consider nonuniform energy transfer rate for solar wind turbulence depending on the solar cycle activity. To achieve this purpose we determine the generalized dimensions and singularity spectra for...

Intermittent oxygen flux from the interior into the bottom boundary of lakes as observed by eddy correlation
Intermittent oxygen flux observed
2014/4/21
Turbulent oxygen transport from the overlying stratified water column into the bottom boundary layer (BBL)
on the slope of a medium-sized lake was investigated using the eddy correlation (EC) techniq...
Modeling the duration of intermittent ice cover on a lake for climate-change studies
climate-change studies intermittent ice
2014/4/17
A generalized empirical approach to the problem of the prediction of intermittent lake ice cover for climatechange studies is presented and applied to historical ice data from Mu¨ggelsee, a shallow la...
A conditional simulation model of intermittent rain fields
Space-time rainfall Conditioning Stochastic models
2009/3/24
The synthetic generation of random fields with specified probability distribution, correlation structure and probability of no-rain areas is used as the basis for the formulation of a stochastic space...
