Versatile Magneto‐Dielectric Response of Epitaxial Thin Films of the High Entropy Oxide Perovskite Nd(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3

Advanced Materials, Volume 38, Issue 26, 8 May 2026.
The magnetic high entropy oxide perovskite Nd(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3 exhibits a substantially large dielectric constant (εr) at room temperature, which shows distinct anionic and cationic contributions in the form of zero and finite bias peaks, respectively, down to its magnetic transition temperature (Tmag).

Evaluation Method and Impact of Clean Energy on the Ecotourism Competitiveness of Townships

Engineering Reports, Volume 8, Issue 5, May 2026.
This study develops an integrated evaluation framework to analyse the impact of clean energy adoption on the ecotourism competitiveness of rural townships. By applying the fuzzy Delphi method (FDM), analytic network process (ANP) and DEMATEL, the research identifies and prioritizes key indicators linking clean energy, sustainability and tourism ...

An empirical framework for many‐to‐one matching markets

Quantitative Economics, Volume 17, Issue 2, Page 590-621, May 2026.
I build a model of many‐to‐one matching with nontransferable utility involving many agents on both sides of the market, for example, workers and firms. Under parsimonious assumptions on preferences and assuming that matches are stable, I provide a tractable asymptotic characterization of the joint distribution of match characteristics.

Identification through sparsity in factor models: The ℓ1‐rotation criterion

Quantitative Economics, Volume 17, Issue 2, Page 461-496, May 2026.
Linear factor models are generally not identified. We provide sufficient conditions for identification: Under a natural sparsity assumption (the presence of local factors that affect only subsets of observables), the true loading matrix is the sparsest rotation and can be recovered by minimizing the ℓ1‐norm of the loading matrix.

Load‐Bearing Characteristics of SLA‐Fabricated Octahedral Porous Structures

Strain, Volume 62, Issue 2, April 2026.
A combined experimental–numerical framework was developed to evaluate SLA–fabricated octahedral and pillar–reinforced lattice structures under compression, shear, and torsion. Small increases in infill density produced nonlinear gains in stiffness and strength, reaching a 255% rise in elastic modulus at low porosity. Pillar reinforcement enhanced shear

Econometric Modelling of the Impact of Metrology on the Economy in Poland

Folia Oeconomica Stetinensia
Studying the impact of metrology on the economy is a complicated matter. This is due to the specific nature of both metrology and the economy. There is no established method for determining the impact of metrology on the economy.

Roll‐to‐Roll Mechanical Exfoliation for Large‐Area van der Waals Films with Preserved Crystallographic Alignment

Advanced Functional Materials, Volume 36, Issue 25, 26 March 2026.
A roll‐to‐roll exfoliation method is demonstrated that preserves the crystallographic alignment of anisotropic 2D materials over large areas, enabling scalable fabrication of directional electronic and optoelectronic devices. Abstract Anisotropic 2D materials such as black phosphorus (BP), GeS or CrSBr, exhibit direction‐dependent optical and ...

The Spatial Fay-Herriot Model in Poverty Estimation

Folia Oeconomica Stetinensia, 2016
Counteracting poverty is one of the objectives of the European Commission clearly emphasized in the Europe 2020 strategy. Conducting appropriate social policy requires knowledge of the extent of this phenomenon.
