Polaron spectral properties in doped ZnO and SrTiO_{3} from first principles

open access: yesPhysical Review Research, 2020
We reveal polaron signatures in the spectral function of n-doped SrTiO_{3} and ZnO through first-principles interacting Green's function calculations. In SrTiO_{3} we observe a clear replica band at 94 meV below the conduction band, which shows that the ...

Integrated Experimental, Chemometric, and In Silico Analyses of Larvicidal Supercritical Extracts From Myrtaceae Species Against Aedes aegypti

open access: yesChemistry &Biodiversity, Volume 23, Issue 10, October 2026.
The cross‐validated regression tree showed modest predictive performance. Mortality was not significantly associated with the first two PCA axes. Molecular modeling generated testable ligand–target hypotheses. Psidium cattleianum had lower LD50. The larvicidal activity of the crude extracts could not be attributed to individual constituents.

Isolation of flow and nonflow correlations by two- and four-particle cumulant measurements of azimuthal harmonics in sNN=200 GeV Au+Au collisions

open access: yesPhysics Letters B, 2015
A data-driven method was applied to Au+Au collisions at sNN=200 GeV made with the STAR detector at RHIC to isolate pseudorapidity distance Δη-dependent and Δη-independent correlations by using two- and four-particle azimuthal cumulant measurements.

Cumulant Structures of Entanglement Entropy

open access: yes
We present a new method to derive exact cumulant expressions of any order of von Neumann entropy over Hilbert–Schmidt ensemble. The new method uncovers hidden cumulant structures that decouple each cumulant in a summation-free manner into its lower-order

Particle Size Measurement of Organic Nanocarriers: A Case Study Using Polyacrylate‐Based Polymer Nanocarriers [PDF]

open access: yesSmall Sci
Sensitivity, detection limits and applicability of size measurement techniques to polymer nanocarriers (PNCs) are investigated. PTA and DCS do not detect PNCs <50 nm and PTA requires adapting concentrations to each PNC, challenging comparisons. Spherical assumptions challenge interpretation by DLS, PTA, and DCS. Cryo‐TEM detects PNCs <50 nm.

Viscoelastic Engineering and Thermoreversibility of Aqueous TiO2 Sol–Gels for Efficient Photocatalytic Coatings

open access: yesMacromolecular Materials and Engineering, Volume 311, Issue 10, October 2026.
Temperature‐controlled ageing tailors water‐based TiO2 sols by linking viscosity evolution to coating formation and photocatalytic performance. Incubation at 50°C (T‐i) promotes optimal aggregation, producing dense and uniform nanocrystalline anatase coatings with near‐complete HCHO degradation.

Probabilistic load flow method considering large-scale wind power integration

open access: yesJournal of Modern Power Systems and Clean Energy, 2019
The increasing penetration of wind power brings great uncertainties into power systems, which poses challenges to system planning and operation. This paper proposes a novel probabilistic load flow (PLF) method based on clustering technique to handle ...

The Role of Dendritic Spines in Water Exchange Measurements With Diffusion MRI: Time‐Dependent Single Diffusion Encoding MRI

open access: yesNMR in Biomedicine, Volume 39, Issue 10, October 2026.
Geometric exchange between dendritic spines and shafts is often neglected, yet it exhibits the same signature as permeative exchange, biasing NEXI/SMEX measurements. We propose two models: an extended three‐compartment Kärger model that resolves spine–shaft exchange explicitly, and a coarse‐grained Kärger model that absorbs spines into an effective ...

Accessibility Measurement by the Cumulative-Opportunity Method

open access: yesJapanese Journal of Human Geography, 1986
An understanding of multi-dimensional regional structure is indispensable in regional planning. Accessibility is one of the most useful indices. Measures of accessibility are grouped according to method of calculation into three types, namely the network measure (formula 2), potential measure (the measure of population potential-type is formula 3, and ...
