Force-Velocity Profiling among Different Maturational Stages in Young Soccer Players: A Cross-Sectional Study

open access: yesInternational Journal of Strength and Conditioning
Speed is a key component of football performance. An individualized approach may be necessary to achieve optimal speed development. Force-velocity profiling breaks down linear sprint performance into force, velocity, and mechanical effectiveness on an ...

The kinematic signature of the inspiral phase of massive binary black holes

open access: yes, 2013
Supermassive black holes are expected to pair as a result of galaxy mergers, and form a bound binary at parsec or sub-parsec scales. These scales are unresolved even in nearby galaxies, and thus detection of non-active black hole binaries must rely on ...

Interseismic coupling and seismic potential along the Central Andes subduction zone [PDF]

open access: yes, 2011
We use about two decades of geodetic measurements to characterize interseismic strain build up along the Central Andes subduction zone from Lima, Peru, to Antofagasta, Chile.

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

open access: yesAdvanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Analysis of Force–Velocity Profiles in Young Football Players: Effect of Competition Level and Position

open access: yesApplied Sciences
We evaluated the force–velocity profiles of young male football players and examined the associations between their competitive levels and positional roles. Thirty-eight male players from a team registered with the National Football Federation who had an

Resonant Absorption in the AGN spectra emerging from photoionized gas: differences between steep and flat ionizing continua [PDF]

open access: yes, 1998
We present photoionization models accounting for both photoelectric and resonant absorption. Resonance absorption lines from C, O, Ne, Mg, Si S and Fe between 0.1 and 10 keV are treated.

Velocity Saturation in Digital Microfluidics.

open access: yesLangmuir, 2019
In digital microfluidics, discrete droplets of fluid are made to move on an open surface with no microchannels. These systems are commonly operated by application of electrical driving forces to an array of electrodes. While these driving forces are well

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

open access: yesAdvanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Analytical Modeling of Wind Farms: A New Approach for Power Prediction

open access: yesEnergies, 2016
Wind farm power production is known to be strongly affected by turbine wake effects. The purpose of this study is to develop and test a new analytical model for the prediction of wind turbine wakes and the associated power losses in wind farms.

Offshore Turbine Arrays: Numerical Modeling and Experimental Validation [PDF]

open access: yes, 2015
The interaction between wind turbines in a large wind farm needs to be better understood to reduce array losses and improve energy production. A numerical test bed for an array of offshore wind turbines was developed in the open-source computational ...
