Carbohydrate intake of 10 g/kg body mass rapidly replenishes liver, but not muscle glycogen contents, during 12 h of post‐exercise recovery in well‐trained cyclists

The Journal of Physiology, EarlyView.
Abstract figure legend Exhaustive cycling exercise substantially reduces liver and muscle glycogen stores. During 12 h of post‐exercise recovery without carbohydrate intake, glycogen stores remain depleted. In contrast, when carbohydrate is consumed at 10 g/kg body mass (BM), provided during the first 6 h as sucrose beverages (1.2 g/kg BM/h), liver ...

Calibration‐Free GRAPE pTx Pulses for Homogeneous Spatial‐Selective Excitation at 7T

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3104-3115, June 2026.
ABSTRACT Purpose Extend the universal pulse GRAPE formalism to pulses with a defined spectral response, and apply the concept to spatial selection. Methods We added Bloch simulations at several frequencies for each voxel to the pulse calculation to create universal spectrally‐selective GRAPE pulses.

Dual-band HF-UHF RFID tag antenna

Electronics Letters, 2009
A dual-band HF and UHF RFID tag antenna with two feeding points is presented, fabricated and measured. A convenient HF resonance is obtained with an HF ASIC chip as well as good impedance matching with UHF ASIC chip in the European RFID UHF band. Tuning techniques of the design parameters are proposed, and tag performance in both frequency bands is ...

Motion‐ and Field‐Robust Mesoscopic Whole‐Brain T2*$$ {T}_2^{\ast } $$‐Weighted Imaging at 7 and 11.7 T Using Servo Navigation

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2658-2670, May 2026.
ABSTRACT Purpose To mitigate artifacts related to motion and field changes in high‐resolution T2*$$ {T}_2^{\ast } $$‐weighted human brain imaging using servo navigation at ultra‐high fields up to 11.7 T. Methods MR‐based servo navigators were integrated into a segmented 3D‐EPI sequence to allow for prospective correction of involuntary head motion and ...

A random walk model of wave propagation [PDF]

, 2004
This paper shows that a reasonably accurate description of propagation loss in small urban cells can be obtained with a simple stochastic model based on the theory of random walks, that accounts for only two parameters: the amount of clutter and the ...
