Article Abstract

The pulse dynamics operating in dissipative soliton resonance (DSR) region is experimentally investigated in a fiber ring laser. With the increase of pump power, the pulse profile transit from sech-like to rectangular shape was observed. The generated pulse in DSR region exhibits the conventional soliton spectrum with sideband generation. The duration-tuning range of the rectangular pulse is up to the cavity roundtrip time. Particularly, during the process of pulse duration broadening it was found that the rectangular pulse would trap a weak pulse generated from cw background. The obtained results may be useful for better understanding the DSR phenomenon.

Synchrotron light sources are powerful platforms for cutting-edge, multidisciplinary research, with dozens currently in operation, construction or commissioning worldwide. It is widely recognized that different research areas have specific demands for source capabilities. For the majority of synchrotron facilities, delivering high-brightness, high-flux synchrotron radiation stably through high-current electron beams is the primary mode of operation.

Background: Catheter ablation is beneficial in patients with symptomatic persistent atrial fibrillation (PerAF), and pulsed field ablation (PFA) is a promising energy source to safely and durably create ablation lesions. However, catheter-specific "PFA waveforms and designs" result in effectiveness and safety profiles that are not transferable to other PFA technologies. A head-to-head comparison between the dual-energy, wide-footprint lattice-tip (Sphere-9, Medtronic) and pentaspline PFA catheter (Farawave, Boston Scientific) is not yet available.

Background: super-refractory status epilepticus (SRSE) is a rare and severe neurological condition associated with high mortality and significant long-term morbidity. In many cases, conventional medical treatments prove ineffective, with wide use of off-label therapies.

Methods: two researchers conducted a review of the medical records of subjects who had undergone VNS implantation in our tertiary Centre.
