Higher order fluctuations and correlations of conserved charges from lattice QCD

open access: yesJournal of High Energy Physics, 2018
We calculate several diagonal and non-diagonal fluctuations of conserved charges in a system of 2+1+1 quark flavors with physical masses, on a lattice with size 483 × 12. Higher order fluctuations at μ B = 0 are obtained as derivatives of the lower order

A general procedure for detector–response correction of higher order cumulants [PDF]

open access: yesNuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2018
We propose a general procedure for the detector-response correction (including efficiency correction) of higher order cumulants observed by the event-by-event analysis in heavy-ion collisions. This method makes use of the moments of the response matrix characterizing the property of a detector, and is applicable to a wide variety of response matrices ...

Sparse Causal Dynamic Linear Regression

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT We develop a sparse causal dynamic regression framework for long multivariate time series. With very long time series, the potentially large number of lags and leads in a dynamic regression model often makes time‐domain estimation numerically unstable or intractable.

Investigation of the linear and mode-coupled flow harmonics in Au+Au collisions at sNN = 200 GeV

open access: yesPhysics Letters B, 2020
Flow harmonics (vn) of the Fourier expansion for the azimuthal distributions of hadrons are commonly employed to quantify the azimuthal anisotropy of particle production relative to the collision symmetry planes.

Variance Ratio Tests for Panels With Cross‐Section Dependence

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT This paper develops panel variance ratio statistics to examine serial dependence in time series with cross‐sectional dependence. We derive asymptotic properties for panels where the cross‐section dimension N$$ N $$ is fixed or grows with T. Using a factor structure to explain cross‐sectional dependence, we propose a common correlation effects ...

Time Averaged CCE

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT A popular approach to interactive effects panel data models is the common correlated effects (CCE) estimator of Pesaran (Estimation and inference in large heterogeneous panels with a multifactor error structure. Econometrica 74, 967–1012, 2006). The current paper proposes a modified version of this estimator that is useful in a number of cases

Measurements of charged-particle multiplicity dependence of higher-order net-proton cumulants in p + p collisions at s=200 GeV from STAR at RHIC

open access: yesPhysics Letters B
We report on the charged-particle multiplicity dependence of net-proton cumulant ratios up to sixth order from s=200 GeV p+p collisions at the Relativistic Heavy Ion Collider (RHIC).

Probing the Structure and Thermoresponsive Behavior of Multicompartment Micelles by Combined Solution‐ and Solid‐State NMR Spectroscopy

open access: yesAnalysis &Sensing, Volume 6, Issue 5, September 2026.
Combined solution‐ and solid‐state NMR spectroscopy is used to probe chain rearrangements in thermoresponsive PNIPAM‐based micelles. We show how core composition affects micellar dynamics and chain mobility across the LCST transition of PNIPAM.

Cumulants of the multiplicity distributions of identified particles measured in heavy-ion collisions by HADES [PDF]

open access: yesEPJ Web of Conferences
The HADES experiment investigates the reaction products of heavy-ion collisions at a few GeV, providing access to QCD matter at high net-baryon densities. A particular focus is the reconstruction of higher-order cumulant ratios of proton and light nuclei

Protein‐Stabilized Copper Nanoclusters for Microbial Inhibition‐Enabled Fresh Produce Preservation and Pesticide Removal

open access: yescMat, Volume 3, Issue 3, September 2026.
Biocompatible bovine serum albumin‐stabilized copper nanoclusters (Cu@BSA NCs) were engineered to integrate potent antimicrobial activity with efficient pesticide adsorption. The dual mechanism, involving Cu species/ROS‐mediated microbial inactivation and BSA‐facilitated pesticide capture, enables simultaneous extension of fresh produce shelf‐life by ≥
