Excitations of the torelon [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 2004
The excitations of gluonic flux tube in a periodic lattice are examined. Monte Carlo simulations from an anisotropic lattice are presented and the comparison with effective string models is discussed.

Engram Excitement [PDF]

open access: yesNeuron, 2019
Engram cells can encode and switch between multiple mnemonic functions, but how they intrinsically do so is unknown. Pignatelli, Ryan, and colleagues show that upon memory recall, the engram's excitability is transiently elevated, allowing its bearer to adapt to changing environments.

Angular Distribution of Characteristic Radiation Following the Excitation of He-Like Uranium in Relativistic Collisions

open access: yesAtoms, 2021
In this paper, we present an experimental and theoretical study of excitation processes for the heaviest stable helium-like ion, that is, He-like uranium occurring in relativistic collisions with hydrogen and argon targets.

Coherent versus incoherent excitation dynamics in dissipative many-body Rydberg systems [PDF]

open access: yes, 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]

open access: yesNeuroscience 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.

The enigmatic function of chandelier cells

open access: yesFrontiers in Neuroscience, 2010
Chandelier (or axo-axonic) cells are one of the most distinctive GABAergic interneurons in the brain. Their exquisite target specificity for the axon initial segment of pyramidal neurons, together with their GABAergic nature, long suggested the ...

Roundabout relaxation: collective excitation requires a detour to equilibrium [PDF]

open access: yes, 2004
Relaxation to equilibrium after strong and collective excitation is studied, by using a Hamiltonian dynamical system of one dimensional XY model. After an excitation of a domain of $K$ elements, the excitation is concentrated to fewer elements, which are

Pre-excitation or post-excitation [PDF]

open access: yesHeart, 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 …

Genetic controls balancing excitatory and inhibitory synaptogenesis in neurodevelopmental disorder models

open access: yesFrontiers in Synaptic Neuroscience, 2010
Proper brain function requires stringent balance of excitatory and inhibitory synapse formation during neural circuit assembly. Mutation of genes that normally sculpt and maintain this balance results in severe dysfunction, causing neurodevelopmental ...
