On the Lukacs property for free random variables [PDF]

, 2014
The Lukacs property of the free Poisson distribution is studied here. We prove that if free $\X$ and $\Y$ are free Poisson distributed with suitable parameters, then $\X+\Y$ and $\left(\X+\Y\right)^{-\frac{1}{2}}\X\left(\X+\Y\right)^{-\frac{1}{2}}$ are ...

What Insights Do Short-Maturity (7DTE) Return Predictive Regressions Offer about Risk Preferences in the Oil Market?

Commodities
In this study, we investigate the ability of three higher-order risk-neutral return cumulants to predict short maturity (weekly) returns of oil futures. Our data includes weekly West Texas Crude Oil futures options that expire in 7 days (7DTE).

Microcanonical free cumulants in lattice systems

Physical Review B
Recently, the full version of the Eigenstate Thermalization Hypothesis (ETH) has been systematized using Free Probability. In this paper, we present a detailed discussion of the Free Cumulants approach to many-body dynamics within the microcanonical ensemble.

Bio‐Inspired Magnetically Tunable Structural Colors from Elliptical Self‐Assembled Block Copolymer Microparticles

Advanced Functional Materials, EarlyView.
Cephalopod‐inspired photonic microparticles with dynamic structural coloration are fabricated via confined self‐assembly of linear block copolymers into ellipsoids containing stacked lamellae. Embedded superparamagnetic nanoparticles enable rapid magnetic alignment, restoring vivid, angle‐dependent color.

Dual‐Functional Polyphosphoesters for Gene Delivery: Synergistic Effects of Guanidinium and Hydrophobic Side Chains in Degradable Polymers

Advanced Healthcare Materials, EarlyView.
This study presents guanidinium‐ and indole‐functionalized polyphosphoesters as degradable, non‐viral gene delivery vectors. Through precise tuning of charge density and hydrophobicity, these polymers form stable polyplexes with low toxicity. Remarkably, minor structural changes yield up to 200‐fold differences in transfection efficiency, highlighting ...

Finite-Size Scaling at Phase Coexistence

, 1993
{}From a finite-size scaling (FSS) theory of cumulants of the order parameter at phase coexistence points, we reconstruct the scaling of the moments.

Porous Iridium Oxide Inverse Opal Catalysts Enable Efficient PEM Water Electrolysis

Advanced Materials, EarlyView.
Porous iridium‐based inverse opal (IrOx‐IO) structures are introduced as high‐performance, unsupported PEM‐WE anode catalysts. Their electrochemical behavior is analyzed through porosity/surface area tuning, voltage breakdown, and circuit modeling.

Lagrange inversion formula, Laguerre polynomials and the free unitary Brownian motion

, 2016
This paper is devoted to the computations of some relevant quantities associated with the free unitary Brownian motion. Using the Lagrange inversion formula, we first derive an explicit expression for its alternating star cumulants of even lengths and ...

A group-theoretical approach to conditionally free cumulants [PDF]

, 2020
In this work we extend the recently introduced group-theoretical approach to moment-cumulant relations in non-commutative probability theory to the notion of conditionally free cumulants. This approach is based on a particular combinatorial Hopf algebra which may be characterised as a non-cocommutative generalisation of the classical unshuffle Hopf ...
