Coherent versus incoherent excitation dynamics in dissipative many-body Rydberg systems [PDF]
, 2014 We study the impact of dephasing on the excitation dynamics of a cloud of ultracold two-level Rydberg atoms for both resonant and off-resonant laser excitation, using the wave function Monte Carlo (MCWF) technique.

Exciting and not so exciting roles of pannexins [PDF]
Neuroscience Letters, 2019 It is the current view that purinergic signaling regulates many physiological functions. Pannexin1 (Panx1), a member of the gap junction family of proteins is an ATP releasing channel that plays important physio-pathological roles in various tissues, including the CNS.

Isospin structure of one- and two-phonon GDR excitations [PDF]
, 1998 Isospin is included in the description of Coulomb excitation of multiple giant isovector dipole resonances. In the excitation of even-even nuclei, a relevant portion of the excitation strength is shown to be associated with 1+ two-phonon states, which ...

Molecules, 2021 Many of the current innovations in instrument design have been focused on making them smaller, more rugged, and eventually field transportable. The ultimate application is obvious, carrying the instrument to the field for real time sample analysis ...

Pre-excitation or post-excitation [PDF]
Heart, 2000 Editor,—We read with great interest the case study by Lau et al entitled “A new ECG sign of an accessory pathway in sinus rhythm: pseudo partial right bundle branch block”.1 However, ventricular pre-excitation can change any part of QRS; the sole …

Momentum-resolved charge excitations in high-Tc cuprates studied by resonant inelastic x-ray scattering [PDF]
, 2007 We report a Cu K-edge resonant inelastic x-ray scattering (RIXS) study of high-Tc cuprates. Momentum-resolved charge excitations in the CuO2 plane are examined from parent Mott insulators to carrier-doped superconductors.

Cardiac tissue engineering [PDF]
Journal of the Serbian Chemical Society, 2005 We hypothesized that clinically sized (1-5 mm thick),compact cardiac constructs containing physiologically high density of viable cells (≈108 cells/cm3) can be engineered in vitro by using biomimetic culture systems capable of providing oxygen transport ...

Roper Excitation in Alpha-Proton Scattering [PDF]
, 1995 We study the Roper excitation in the $(\alpha,\alpha')$ reaction. We consider all processes which may be relevant in the Roper excitation region, namely, Roper excitation in the target, Roper excitation in the projectile, and double $\Delta$ excitation ...

Journal of Magnetic Resonance, 2017 The paper describes the design of broadband chirp excitation pulses in NMR. We first develop a three stage model for understanding chirp excitation in NMR. We then show how a chirp $ $ pulse can be used to refocus the phase of the chirp excitation pulse. The resulting magnetization still has some phase dispersion in it.
