The monotonicity results and sharp inequalities for some power-type means of two arguments [PDF]

open access: yes, 2012
For $a,b>0$ with $a\neq b$, we define M_{p}=M^{1/p}(a^{p},b^{p})\text{if}p\neq 0 \text{and} M_{0}=\sqrt{ab}, where $M=A,He,L,I,P,T,N,Z$ and $Y$ stand for the arithmetic mean, Heronian mean, logarithmic mean, identric (exponential) mean, the first ...

A Rate-Splitting Approach to Fading Channels with Imperfect Channel-State Information

open access: yes, 2014
As shown by M\'edard, the capacity of fading channels with imperfect channel-state information (CSI) can be lower-bounded by assuming a Gaussian channel input $X$ with power $P$ and by upper-bounding the conditional entropy $h(X|Y,\hat{H})$ by the ...

The intersection of health inequalities and COVID‐19: Evidence from National Health Insurance Big Data in South Korea

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Health inequalities persist along lines of income and wealth, shaped by unequal access to healthcare, differences in health behaviors, and pre‐existing chronic conditions. The COVID‐19 pandemic further put families in Korea under health strain and worsened their health outcomes.

On some inequalities for the matrix power and Karcher means

open access: yesLinear Algebra and its Applications, 2013
The authors have establish a useful inequality for matrix power means of positive definite matrices. The paper provides a simple proof of the convergence of power means to the Karcher mean. Some new matrix mean inequalities on the Karcher and power means are presented.

The psychosocial toll of Dublin III on asylum seekers in the Netherlands

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract The Dublin III Regulation determines which EU Member State is responsible for examining asylum claims, but its implementation carries significant consequences for those subjected to it. This study examines how Dublin III, as implemented in the Netherlands, affects asylum seekers' psychosocial wellbeing using Silove′s Adaptation and Development

Norm inequalities for weighted power means of operators

open access: yesLinear Algebra and its Applications, 2002
Let \(A_{i}\), \(X_{i}\) and \(Y_{i}\) be bounded linear operators on a Hilbert space for \(i=1,2,\dots ,n\). In the present paper, the authors prove the following norm inequalities: (i) If \(\sum_{i=1}^{n}X^{*}_{i}X_{i}\leq I\), \(\sum_{i=1}^{n}Y^{*}_{i}Y_{ i}\leq I\) and \(r\geq 1\), then \[ \Bigg|\Bigg|\Bigg|\Bigg |\sum_{i =1}^{n} X_{i}^{*}A_{i}Y_{i}
