Microelectrode and His Bundle Studies on Type I and II Second Degree A-V Block [PDF]

, 1973
Mobitz classified second degree A-V block into two categories. Mobitz type I, or Wenckebach block, is characterized by a gradual prolongation of the P-R interval preceding the dropped ventricular beat.

When Cellulose Moves: Smart Sensors and Actuators

Advanced Materials Technologies, EarlyView.
This review highlights cellulose‐derived soft actuators alongside with cellulose‐based sensors. Emphasis is placed on their integration into multifunctional devices that couple sensing and actuation to mimic natural motion and adaptability. We also discuss the challenges of achieving robust, reversible, and multi‐stimuli‐responsive motion, and outline ...

Strong and Weak Coupling Nanophysics with Free Electron Beams

Advanced Optical Materials, EarlyView.
This paper focuses on a short review of the study of the coupling between optical excitations at the nanometer scale, made possible by recent advances in free electron beam spectroscopies. In particular, plasmon–plasmon, plasmon–exciton, and plasmon–phonon couplings are reviewed. Abstract The work of Luis M.
