Short Remarks on Complete Monotonicity of Some Functions

Mathematics, 2020
In this paper, we show that the functions x m | β ( m ) ( x ) | are not completely monotonic on ( 0 , ∞ ) for all m ∈ N , where β ( x ) is the Nielsen’s β -function and we prove the functions x m − 1

Orientations of Graphs With at Most One Directed Path Between Every Pair of Vertices

Journal of Graph Theory, EarlyView.
ABSTRACT Given a graph G $G$, we say that an orientation D $D$ of G $G$ is a KT orientation if, for all u , v ∈ V ( D ) $u,v\in V(D)$, there is at most one directed path (in any direction) between u $u$ and v $v$. Graphs that admit such orientations have been used to construct graphs with large chromatic number and small clique number that served as ...

Income inequality and alcohol attributable harm in Australia

BMC Public Health, 2009
Background There is little research on the relationship between key socioeconomic variables and alcohol related harms in Australia. The aim of this research was to examine the relationship between income inequality and the rates of alcohol-attributable ...

On a Clique‐Building Game of Erdős

Journal of Graph Theory, EarlyView.
ABSTRACT The following game was introduced in a list of open problems from 1983 attributed to Erdős: two players take turns claiming edges of a Kn ${K}_{n}$ until all edges are exhausted. Player 1 wins the game if the largest clique that they claim at the end is strictly larger than the largest clique of their opponent; otherwise, Player 2 wins the ...

A Power‐Efficient Monte Carlo Framework for Nonlinear Light–Matter Interactions: In Silico Modeling of Spontaneous and Stimulated Raman Scattering in Turbid Media

Journal of Raman Spectroscopy, EarlyView.
Power‐efficient Monte Carlo modeling of nonlinear light–matter interactions in turbid media is demonstrated using Apple Silicon–accelerated photon transport. The Metal‐base framework enables accurate simulation of spontaneous and stimulated Raman scattering, revealing detection‐dependent SRS efficiency while providing a scalable, energy‐efficient ...

Weighted Inequalities for Quasi-Monotone Functions

Journal of the London Mathematical Society, 1998
The purpose of this paper is to give characterizations of weights for which reverse inequalities of the Hölder type for quasi-monotone functions are satisfied. Our inequalities with general weights and with sharp constants complement the results of Bergh-Burenov-Persson (1994), Heinig-Maligranda (1995), Heinig-Stepanov (1993) and Stepanov (1993, 1994 ...

Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies

Laser &Photonics Reviews, EarlyView.
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.

Characterization of the trace by monotonicity inequalities

Linear Algebra and its Applications, 2007
Let \(\phi \) be a positive linear functional on the algebra of \(n\times n\) complex matrices and let \(A,B\) be any pair of \(n\times n\) positive semi-definite matrices such that \(A\leq B.\) The authors prove that if the inequality \(\phi (f(A))\leq \phi (f(B))\) holds true when \(f(x)= x^p, p>1,\) or \(f(x)= (x+\lambda )^p, p>1, \lambda >0,\) or \(
