On a multiple Hilbert-type integral inequality involving the upper limit functions

open access: yesJournal of Inequalities and Applications, 2021
By applying the weight functions, the idea of introducing parameters and the technique of real analysis, a new multiple Hilbert-type integral inequality involving the upper limit functions is given.

The Temperature-Density Relation in the Intergalactic Medium at Redshift =2.4 [PDF]

open access: yes, 2012
We present new measurements of the temperature-density (T-rho) relation for neutral hydrogen in the 2.0 < z < 2.8 intergalactic medium (IGM) using a sample of ~6000 individual HI absorbers fitted with Voigt profiles constrained in all cases by multiple ...

A new method for the empirical conversion of logging data to clay mineral fraction in the Nankai accretionary prism

open access: yesEarth, Planets and Space, 2020
Sediment lithology, especially the clay mineral fraction, is basic geologic information, which is important for understanding faulting and evolutionary process of the accretionary prism.

Quantifying angular clustering in wide-area radio surveys [PDF]

open access: yes, 2002
We quantify the angular clustering of radio galaxies in the NVSS and FIRST radio surveys using the two-point correlation function and the moments of counts-in-cells - both important points of comparison with theory.

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.

The multiple gamma functions and the multiple q-gamma functions

open access: yes, 1996
We give an asymptotic expansion (the higher Stirling formula) and an infinite product representation (the Weierstrass product representation) of the Vign ras multiple gamma functions by considering the classical limit of the multiple q-gamma functions.

Bayesian Model Comparison and Analysis of the Galactic Disk Population of Gamma-Ray Millisecond Pulsars [PDF]

open access: yes, 2018
Pulsed emission from almost one hundred millisecond pulsars (MSPs) has been detected in $\gamma$-rays by the Fermi Large-Area Telescope. The global properties of this population remain relatively unconstrained despite many attempts to model their spatial

Modeling Gamma-Ray Burst X-Ray Flares within the Internal Shock Model [PDF]

open access: yes, 2009
X-ray afterglow light curves have been collected for over 400 Swift gamma-ray bursts with nearly half of them having X-ray flares superimposed on the regular afterglow decay.

Multiple Gamma Function and Its Application to Computation of Series

open access: yes, 2003
The multiple gamma function $\Gamma_n$, defined by a recurrence-functional equation as a generalization of the Euler gamma function, was originally introduced by Kinkelin, Glaisher, and Barnes around 1900.

Likelihood based inference for current status data on a grid: A boundary phenomenon and an adaptive inference procedure [PDF]

open access: yes, 2011
In this paper, we study the nonparametric maximum likelihood estimator for an event time distribution function at a point in the current status model with observation times supported on a grid of potentially unknown sparsity and with multiple subjects ...
