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 ...

Surface Plasmon Microscopy Versus Optical Microscopy: Ez Dominates in SPM

open access: yesIEEE Photonics Journal, 2020
Objective-coupled surface plasmon microscopy (SPM) shows extremely high similarity with conventional optical microscopy (OM) in both configuration and theoretical model.

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.

Layer Specific Development of Neocortical Pyramidal to Fast Spiking Cells Synapses.

open access: yesFrontiers in Cellular Neuroscience, 2016
All cortical neurons are engaged in inhibitory feedback loops which ensure excitation-inhibition balance and are key elements for the development of coherent network activity.

Moving toward a Handheld “Plasma” Spectrometer for Elemental Analysis, Putting the Power of the Atom (Ion) in the Palm of Your Hand

open access: yesMolecules, 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 ...

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.

Prediction technique for dynamic stress on bellows exhaust pipe (2) (Dynamic stress analysis of multilayer bellows using equivalent stiffness model)

open access: yesNihon Kikai Gakkai ronbunshu, 2018
We developed a new prediction technique for dynamic stress on a bellows with low computational load, to secure the strength reliability of the multilayer bellows used in the engine exhaust system of hydraulic excavators.

Momentum-resolved charge excitations in high-Tc cuprates studied by resonant inelastic x-ray scattering [PDF]

open access: yes, 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.

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.

Roper Excitation in Alpha-Proton Scattering [PDF]

open access: yes, 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 ...
