Article Synopsis
  • The study investigates the safety and performance of a single-use negative pressure wound therapy (suNPWT) system on closed surgical incisions that are at risk of complications.
  • It utilized a prospective, open, non-comparative, multicentre design with 35 patients, measuring outcomes like wound closure rates and any adverse events over a 14-day period.
  • Results showed that all wounds remained closed, exhibited low infection rates, and reported minimal pain, indicating the suNPWT system is effective and safe for managing closed surgical incisions.

We present a joint experimental-theoretical study on the effect of the carrier-envelope phase (CEP) of a few-cycle pulse on the atomic excitation process. We focus on the excitation rates of argon at intensities in the transition between the multiphoton and tunneling regimes. Through numerical simulations, we show that the resulting bound-state population is highly sensitive to both the intensity and the CEP.

Context: The role of robot-assisted surgery continues to expand at a time when trainers and proctors have travel restrictions during the coronavirus disease 2019 (COVID-19) pandemic.

Objective: To provide guidance on setting up and running an optimised telementoring service that can be integrated into current validated curricula. We define a standardised approach to training candidates in skill acquisition via telepresence technologies.

Article Synopsis
  • This study investigates the relativistic nondipole effects on atomic ionization using strong laser pulses and high-resolution electron momentum measurements.
  • The researchers utilized a reaction microscope and an advanced theoretical model grounded in the time-dependent Dirac equation to analyze their findings.
  • They observed unexpected shifts in the electron momentum distribution, confirming the accuracy of their experimental results with theoretical predictions.

We have investigated nuclear dynamics in bound and dissociating acetylene molecular ions in a time-resolved reaction microscopy experiment with a pair of few-cycle pulses. Vibrating bound acetylene cations or dissociating dications are produced by the first pulse. The second pulse probes the nuclear dynamics by ionization to higher charge states and Coulomb explosion of the molecule.
