EcoEnergy, EarlyView.Atomically thin Bi5O7Br nanotubes embedded with abundant Bi nanodots were constructed as an efficient photothermal catalyst for CO2 conversion. The localized surface plasmon resonance and photothermal effect of Bi nanodots synergistically enhance light harvesting, charge utilization, and reaction kinetics, resulting in significantly improved CO2 to CO ...

Physics Letters BWe calculate the contribution of the decay products of excited nuclear cluster states to the event-by-event fluctuations of protons in the energy range from sNN=2−5 GeV within the statistical model.

Detecting spatial patterns with the cumulant function – Part 1: The theory [PDF]
Nonlinear Processes in Geophysics, 2008 In climate studies, detecting spatial patterns that largely deviate from the sample mean still remains a statistical challenge. Although a Principal Component Analysis (PCA), or equivalently a Empirical Orthogonal Functions (EOF) decomposition, is often

Statistical temporal pattern extraction by neuronal architecture
Physical Review Research, 2023 Neuronal systems need to process temporal signals. Here, we show how higher-order temporal (co)fluctuations can be employed to represent and process information.

Pion interferometry with higher-order cumulants
, 1996 We have measured second- and third-order cumulants in UA1 data ($\bar pp$ collisions at 630 GeV/c). Rather than quoting numerical values for source parameters, we have used these in three checks to test the ``quantum statistics'' theory for consistency over these cumulants.

Journal of Raman Spectroscopy, EarlyView.In this work, silver nanoparticles encapsulated within quatsome membranes have shown to preserve their plasmonic properties for at least 165 days without aggregation. These hybrid nanostructures enable strong SERS enhancement of pyrene and Prodan by confining the molecules within a few nanometers from the silver surface.

Predicting Statistical Signatures of Collective Emission in Disordered Color Center Ensembles
Laser &Photonics Reviews, EarlyView.We present an efficient simulation framework for modeling collective emission in disordered ensembles of quantum emitters. The low computational complexity enables large‐scale Monte Carlo simulations. Applied to SiV−${\rm SiV}^{-}$ clusters, it predicts thresholded superradiant bursts set by emitter number and quantum efficiency, as well as interaction‐

Linear Causal Disentanglement via Higher-Order Cumulants
La MatematicaAbstract Linear causal disentanglement (LCD) is a recent method in causal representation learning to describe a collection of observed variables via latent variables with causal dependencies between them. It can be viewed as a generalization of both independent component analysis and linear structural equation models.

Magnetic Resonance in Medicine, EarlyView.Purpose The dependence of the long‐time (tortuosity) limit of the extra‐cellular diffusivity on the intra‐cellular volume fraction is of fundamental importance for microstructure modeling. While such dependencies have been explored for the white matter, the tortuosity limit in gray matter is unknown due to complex cell composition and geometry. Here we
