Massive-Scalar Effective Actions on Anti-de Sitter Spacetime [PDF]

open access: yes, 1998
Closed forms are derived for the effective actions for free, massive spinless fields in anti-de Sitter spacetimes in arbitrary dimensions. The results have simple expressions in terms of elementary functions (for odd dimensions) or multiple Gamma ...

On the Multiple Gamma-Functions

open access: yesTokyo Journal of Mathematics, 1998
The authors obtain generalizations of the Shintani type infinite product representations for the \(r\)-ple gamma functions \(\Gamma_r(w;\widetilde\omega)\) and \(r\)-ple Stirling's modular forms \(\rho_r(\widetilde\omega)\) in the sense of Barnes. As an application, ``a simple proof'' of the inversion formulas of theta-function and Dedekind \(\eta ...

Gene expression profiling in cells with enhanced gamma-secretase activity.

open access: yesPLoS ONE, 2009
BackgroundProcessing by gamma-secretase of many type-I membrane protein substrates triggers signaling cascades by releasing intracellular domains (ICDs) that, following nuclear translocation, modulate the transcription of different genes regulating a ...

Theory of Barnes Beta Distributions [PDF]

open access: yes, 2013
A new family of probability distributions $\beta_{M, N},$ $M=0\cdots N,$ $N\in\mathbb{N}$ on the unit interval $(0, 1]$ is defined by the Mellin transform.

The alpha-gamma transition of Cerium is entropy-driven [PDF]

open access: yes, 2005
We emphasize, on the basis of experimental data and theoretical calculations, that the entropic stabilization of the gamma-phase is the main driving force of the alpha-gamma transition of cerium in a wide temperature range below the critical point. Using

Auditory driven gamma synchrony is associated with cortical thickness in widespread cortical areas

open access: yesNeuroImage, 2022
Objective: Gamma synchrony is a fundamental functional property of the cerebral cortex, impaired in multiple neuropsychiatric conditions (i.e. schizophrenia, Alzheimer's disease, stroke etc.). Auditory stimulation in the gamma range allows to drive gamma

Power Spectrum and Connectivity Analysis in EEG Recording during Attention and Creativity Performance in Children

open access: yesNeuroSci, 2022
The present research aims at examining the power spectrum and exploring functional brain connectivity/disconnectivity during concentration performance, as measured by the d2 test of attention and creativity as measured by the CREA test in typically ...

Superimposed gratings induce diverse response patterns of gamma oscillations in primary visual cortex

open access: yesScientific Reports, 2021
Stimulus-dependence of gamma oscillations (GAMMA, 30–90 Hz) has not been fully understood, but it is important for revealing neural mechanisms and functions of GAMMA. Here, we recorded spiking activity (MUA) and the local field potential (LFP), driven by

A Set of Mathematical Constants Arising Naturally in the Theory of the Multiple Gamma Functions

open access: yesAbstract and Applied Analysis, 2012
We introduce a set of mathematical constants which is involved naturally in the theory of multiple Gamma functions. Then we present general asymptotic inequalities for these constants whose special cases are seen to contain all results very recently ...

Multiple Parton Interactions in Z+jets production at the LHC. A comparison of factorized and non--factorized double parton distribution functions [PDF]

open access: yes, 2011
We examine the contribution of Multiple Parton Interactions to Z+n-jets production at the LHC, n=2,3,4, where the Z boson is assumed to decay leptonically.
