On the neglecting of higher-order cumulants in EXAFS data analysis

Journal of Synchrotron Radiation, 2009
The cumulant expansion is one of the most powerful and useful methods for EXAFS data analysis, in which the higher-order cumulants allow to consider deviations from a simple Gaussian distribution. In this work, analytical expressions have been derived to show the effects of neglecting higher-order cumulants in EXAFS analysis by the ratio method.

Buffer and salt dependent reassembly pathways of Myxococcus xanthus encapsulin

Protein Science, Volume 35, Issue 9, September 2026.
Abstract Protein cages that adopt multiple assembly states provide tractable systems for probing the mechanisms that govern icosahedral shell formation. The Myxococcus xanthus encapsulin shell protein assembles into either a T = 1 shell (60 subunits) or a T = 3 shell (180 subunits), making it an ideal model to investigate how solution conditions bias ...

Cumulant expansions for atmospheric flows

New Journal of Physics, 2016
Atmospheric flows are governed by the equations of fluid dynamics. These equations are nonlinear, and consequently the hierarchy of cumulant equations is not closed.

Wavelet‐Based Hurst Exponent Estimation

WIREs Computational Statistics, Volume 18, Issue 3, September 2026.
The review explores how wavelet‐based methods for estimating the Hurst parameters have developed from their theoretical roots to real‐world applications in fields like biology, engineering, and telecommunications. The review aims to highlight key techniques, compare their strengths and limitations, and point out challenges that still need to be ...

Symmetry-based efficient simulation of higher-order coherences in quantum many-body superradiance

Physical Review Research
We propose an efficient method to numerically simulate the superradiant emission dynamics of large numbers of quantum emitters in ordered arrays in the presence of long-range dipole-dipole interactions mediated by the vacuum electromagnetic field.

Estimation of Seismic Wavelets Based on the Multivariate Scale Mixture of Gaussians Model

Entropy, 2009
This paper proposes a new method for estimating seismic wavelets. Suppose a seismic wavelet can be modeled by a formula with three free parameters (scale, frequency and phase).

Adaptive Estimation for Weakly Dependent Functional Times Series

Journal of Time Series Analysis, Volume 47, Issue 5, Page 1013-1027, September 2026.
ABSTRACT We propose adaptive mean and autocovariance function estimators for stationary functional time series under 𝕃p−m‐approximability assumptions. These estimators are designed to adapt to the regularity of the curves and to accommodate both sparse and dense data designs.

Biocompatible Sulfobetaine Polymer‐Artemisinin Conjugates Inducing Ferroptosis in Cancer Cells: Synthesis by Mechanochemical Solid‐State Polymerization and Characterization

Macromolecular Rapid Communications, Volume 47, Issue 15, 4 August 2026.
The amphiphilic copolymer incorporating a hydrophobic chain conjugated with artesunate into a biocompatible sulfobetaine polymer is synthesized by solid‐state copolymerization of sulfobetaine methacrylate and methacrylamide derivative conjugating artesunate.

Restriction‐Weighted Q‐Space Trajectory Imaging (ResQ): Toward Mapping Diffusion‐Time Effects With Tensor‐Valued Diffusion Encoding in Human Prostate Cancer Xenografts

NMR in Biomedicine, Volume 39, Issue 8, August 2026.
Tensor‐valued diffusion MRI enables microstructure characterization but can be confounded by the presence of restricted diffusion. We introduce ResQ, a framework that incorporates restriction weighting into q‐space trajectory imaging and we evaluate it in a longitudinal study of prostate cancer xenografts treated by external radiotherapy. ResQ revealed

Rapidity Dependence of Proton Higher-Order Cumulants in √sNN = 3.2 GeV Au+Au Collisions at RHIC [PDF]

EPJ Web of Conferences
Fluctuations of conserved quantities are proposed as a useful observable to study the QCD phase structure including the search for the first-order phase boundary and critical point [1].
