Generalisation of the Cumulants of Flow Amplitudes to the higher orders

open access: yes, 2021
Studies of the hydrodynamic response of the quark-gluon plasma created in ultra-relativistic heavy-ion collisions to the initial state anisotropies, a phenomenon known as anisotropic flow, allowed the determination of some of the properties of the produced medium.

Hierarchical Bayesian Modelling Improves Microstructural Parameter Mapping in Diffusion and Exchange MRI Data

open access: yesNMR in Biomedicine, Volume 39, Issue 6, June 2026.
Our hierarchical Bayesian modelling (HBM) technique is demonstrated in two neuroimaging diffusion MRI models. When compared with least‐squares (LSQ) minimisation, HBM increased the accuracy, precision, contrast‐to‐noise ratio and parameter map quality in simulated and human data. HBM also resolved local parameter variations associated with white matter

Multifractality in a broad class of disordered systems

open access: yes, 2004
We study multifractality in a broad class of disordered systems which includes, e.g., the diluted x-y model. Using renormalized field theory we analyze the scaling behavior of cumulant averaged dynamical variables (in case of the x-y model the angles ...

Understanding the Phenotypic Heterogeneity Within the Sporadic Creutzfeldt–Jakob Disease MV1 Subtype

open access: yesNeuropathology and Applied Neurobiology, Volume 52, Issue 3, June 2026.
We present the clinical, pathological and prion biophysical features of three atypical cases of the MV1 subtype of sporadic Creutzfeldt–Jakob disease (sCJD). We propose that these heterozygous cases exist on a spectrum ranging from MM1‐like to VV1‐like phenotypes and recommend that subtyping be performed at pH 6.9 to avoid missing atypical or mixed ...

Sample Variance of the Higher-Order Cumulants of Cosmic Density and Velocity Fields

open access: yes, 1998
If primordial fluctuation is Gaussian distributed, higher-order cumulants of the cosmic fields reflect nonlinear mode coupling and provide useful information of gravitational instability picture of structure formation.

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

open access: yesAdvanced Functional Materials, Volume 36, Issue 38, 11 May 2026.
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.

Comparing the Latent Features of Universal Machine‐Learning Interatomic Potentials

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 5, May 2026.
This study quantitatively assesses how universal machine‐learning interatomic potentials encode the chemical space into latent features, showing unique model‐specific representations with high cross‐model reconstruction errors. It explores how training datasets, protocols, and targets affect these encodings.

Constructing probability density function of net-proton multiplicity distributions using Pearson curve method

open access: yes, 2017
The probability density functions of net-proton multiplicity distributions are constructed from the Beam Energy Scan results of the STAR experiment using the Pearson curve method for two different transverse momentum windows.

Dengue Virus Capsid Protein Interaction With Nucleic Acids

open access: yesBioFactors, Volume 52, Issue 3, May/June 2026.
Binding of dengue virus capsid protein (DENV C) to ssDNA alters Trp fluorescence intensity, lifetime, and anisotropy, revealing structural rearrangements in the complex and suggesting a possible association with liquid–liquid phase separation (LLPS). ABSTRACT Dengue virus (DENV) transmission has greatly increased in the last decade, partly due to the ...

Monte Carlo Assessment of Accuracy for Mean Kärger Model Water Exchange Rate Estimates From Diffusional Kurtosis Time Dependence

open access: yesNMR in Biomedicine, Volume 39, Issue 5, May 2026.
Monte Carlo simulations for water diffusing through a packing of parallel, randomly placed, permeable cylinders are used to assess the accuracy of a new diffusion MRI method for estimating the mean water exchange rate in brain. The exchange rate estimate is derived from the logarithmic derivative of the diffusional kurtosis with respect to the ...
