Dynamics of conduction blocks in a model of paced cardiac tissue [PDF]
We study numerically the dynamics of conduction blocks using a detailed electrophysiological model. We find that this dynamics depends critically on the size of the paced region. Small pacing regions lead to stationary conduction blocks while larger pacing regions can lead to conduction blocks that travel periodically towards the pacing region. We show

In vivo transit dosimetry methodology for whole breast intensity modulated radiation therapy
Abstract Background In vivo transit dosimetry using an electronic portal imaging device (EPID‐IVTD) is an important tool for verifying the accuracy of radiation therapy treatments. Despite its potential, the implementation of EPID‐IVTD in breast intensity modulated radiation therapy (IMRT) treatments has not yet been standardized, limiting its clinical

Objective We aimed to characterize patients with hand osteoarthritis (OA) with deteriorating or improving hand pain and to investigate patients achieving good clinical outcome after four years. Methods We used four‐year annual Australian/Canadian Hand Osteoarthritis Index (AUSCAN) pain subscale (range 0–20) measurements from the Hand OSTeoArthritis in ...

Left bundle branch area pacing optimized cardiac resynchronization – a promise of way better?
Conduction system pacing may revolutionize conventional pacemaker therapy. Both His- and left bundle branch area pacing (LBBAP) can prevent right ventricular pacing induced cardiomyopathy in bradycardia pacemaker indications, furtheron they might improve

Self-paced ensemble learning for speech and audio classification [PDF]
Combining multiple machine learning models into an ensemble is known to provide superior performance levels compared to the individual components forming the ensemble. This is because models can complement each other in taking better decisions. Instead of just combining the models, we propose a self-paced ensemble learning scheme in which models learn ...

The fabrication and post‐treatment via solvent annealing of poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate‐based electrodes using spray deposition in a roll‐to‐roll setup are presented. The decrease in sheet resistance and its correlation with nanostructure and molecular structure in the electrodes as a function of the processing parameters is ...

Conduction system pacing in heart failure patients
Direct conduction system pacing delivers more physiological cardiac activation and can potentially correct intraventricular conduction disturbances and restore normal activation pathways. Permanent pacing that maintains cardiac electromechanical synchrony is essential in heart failure and reduced left ventricular ejection fraction.
