80 Hz but not 40 Hz, transcranial alternating current stimulation of 80 Hz over right intraparietal sulcus increases visuospatial working memory capacity

open access: yesScientific Reports, 2022
Working memory (WM) is a complex cognitive function involved in the temporary storage and manipulation of information, which has been one of the target cognitive functions to be restored in neurorehabilitation.

A Hardy–Hilbert-type integral inequality involving two multiple upper-limit functions

open access: yesJournal of Inequalities and Applications, 2023
By means of the weight functions, the idea of introducing parameters and the technique of real analysis, a new Hardy–Hilbert-type integral inequality with the homogeneous kernel 1 ( x + y ) λ ( λ > 0 ) $\frac{1}{(x + y)^{\lambda}}\ (\lambda > 0 ...

Jackson's integral of multiple Hurwitz–Lerch zeta functions and multiple gamma functions [PDF]

open access: yesJournal of Mathematical Analysis and Applications, 2018
Using the Jackson integral, we obtain the $q$-integral analogue of the Raabe type formulas for Barnes multiple Hurwitz-Lerch zeta functions and Barnes and Vardi's multiple gamma functions. Our results generalize $q$-integral analogue of the Raabe type formulas for the Hurwitz zeta functions and log gamma functions in [N. Kurokawa, K.

The Generation and Modulation of Distinct Gamma Oscillations with Local, Horizontal, and Feedback Connections in the Primary Visual Cortex: A Model Study on Large-Scale Networks

open access: yesNeural Plasticity, 2021
Gamma oscillation (GAMMA) in the local field potential (LFP) is a synchronized activity commonly found in many brain regions, and it has been thought as a functional signature of network connectivity in the brain, which plays important roles in ...

Special values of multiple gamma functions [PDF]

open access: yesJournal de théorie des nombres de Bordeaux, 2008
We give a Chowla-Selberg type formula that connects a generalization of the eta-function to GL(n) with multiple gamma functions. We also present some simple infinite product identities for certain special values of the multiple gamma function.

Algorithms to Evaluate Multiple Sums for Loop Computations [PDF]

open access: yes, 2013
We present algorithms to evaluate two types of multiple sums, which appear in higher-order loop computations. We consider expansions of a generalized hypergeometric-type sums, $\sum_{n_1,...,n_N} [Gamma(a1.n+c1) Gamma(a2.n}+c2) ...

Multiple Gamma functions and $L$-functions [PDF]

open access: yesMathematical Research Letters, 1996
Multiple gamma functions, first introduced and studied by E. W. Barnes and others around 1900, play an important role in the study of functional equations for Selberg zeta functions and other topics in modern analytic number theory. This paper makes a case for defining a multiple gamma function as a meromorphic function \(\Gamma_P(u)\) associated with ...

Multiple $$\log \Gamma $$ -Type Functions

open access: yes, 2022
AbstractIn this chapter, we introduce and investigate the map, denote it by Σ, that carries any function g lying in $$\displaystyle \bigcup _{p\geq 0}(\mathcal {D}^p\cap \mathcal {K}^p) $$ ⋃ p ≥ 0

Bounds for triple gamma functions and their ratios

open access: yesJournal of Inequalities and Applications, 2016
In this work, in addition to the bounds for triple gamma function, bounds for the ratios of triple gamma functions are obtained. Similar bounds for the ratios of the double gamma functions are also obtained.
