To Pulse or Not to Pulse, That Is the Question [PDF]
Critical Care Medicine, 2020 We read with interest this succinct review by Keller (1), published in the recent issue of Critical Care Medicine, on the application of peripheral venoarterial extracorporeal membrane oxygenation (ECMO) in cardiogenic shock, the intricate physiologic challenges which arise with its institution, and its lack of definitive guidelines. We note that areas

Solvatochromic and Ligand Effects in Ultrafast Intramolecular Electron Transfer in Fe-based Molecular Photosensitizers [PDF]
EPJ Web of Conferences, 2019 Metal-to-ligand charge-transfer (MLCT) excited state lifetimes of [Fe(CN)4(2,2’-bipyridine)]2- and [Fe(CN)4(2,3-bis(2-pyridyl)pyrazine)]2-exhibit strong solvent and ligand dependence. We conclude that these effects can be described with Marcus-like model

Pulsing and non-pulsing ULXs: the iceberg emerges [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We show that ultraluminous X-ray sources (ULXs) with coherent X-ray pulsing (PULXs) probably have neutron-star spin axes significantly misaligned from their central accretion discs. Scattering in the funnels collimating their emission and producing their apparent super-Eddington luminosities is the most likely origin of the ...

Single-stage GaSe OPCPA delivering high-energy few-cycle pulses at 11 µm wavelength – INVITED [PDF]
EPJ Web of Conferences, 2023 The generation of sub-five optical cycle pulses centered at 11.2 µm wavelength with 50 µJ energy at a 1 kHz repetition rate is reported. A GaSe optical parametric chirped pulse amplifier (OPCPA) is driven by the residual 2.0 µm pump and 5 µm idler of a ...

The Pulse Scale Conjecture and the Case of BATSE Trigger 2193 [PDF]
, 2000 The pulses that compose gamma-ray bursts (GRBs) are hypothesized to have the same shape at all energies, differing only by scale factors in time and amplitude.
