A Long‐Period Grating Formed by Residual Stress on Thin‐Film Lithium Niobate With Efficient Electro‐Optic and Thermo‐Optic Tuning

open access: yesNanophotonics, Volume 15, Issue 9, 13 May 2026.
Three‐dimensional schematic (a) of the proposed long‐period grating (LPG) on thin‐film lithium niobate (TFLN) and its cross‐sectional view (b) showing a TFLN core with a BCB cladding and a periodic metal structure. Residual stress generated at the metal–BCB interface creates the LPG.

Reconfigurable Analog Computing Metasurfaces Based on Thin Film Lithium Niobate

open access: yesNanophotonics, Volume 15, Issue 9, 13 May 2026.
A transmissive reconfigurable analog computing metasurface based on a simple TFLN structure is demonstrated. The proposed metasurface is truly flexible and capable of switching between different computing functions, such as first‐order differentiation, second‐order differentiation, and integration.

Searching for Key Factors in Enterprise Bankrupt Prediction: A Case Study in Slovak Republic

open access: yesEconomics and Culture, 2018
The issue of enterprise in bankrupt or financial health as a whole is still very actual topic not only in Slovakia but also in abroad. Works dealing with the enterprise in bankruptcy have already appeared in the 1930s of the 20th century.

Genetic progress from 15 years of white oat breeding in Brazil

open access: yesCrop Science, Volume 66, Issue 3, May/June 2026.
Abstract Despite advances in crop management and breeding, cereals still face considerable yield losses from phytopathogens and lodging caused by adverse weather. Developing oat genotypes that combine disease tolerance, lodging resistance, and industrial quality is therefore essential, and the estimation of genetic progress allows validation of ...

Links between piezoelectric properties and figures of merit in novel 2–1–2 composites with lead-free ferroelectric components

open access: yesNext Materials
Important links between piezoelectric coefficients and energy-harvesting figures of merit are studied in novel 2–1–2 composites with two ferroelectric components ([001]-poled single crystals and ceramics), which are chosen among alkali niobates ...

Time‐Varying Gravity Constraints on Groundwater Recharge and Managed Aquifer Strategies in Southern Taiwan

open access: yesWater Resources Research, Volume 62, Issue 4, April 2026.
Abstract Understanding groundwater recharge pathways is essential for designing effective managed aquifer strategies, yet in heterogeneous alluvial aquifers, these pathways are often uncertain and difficult to resolve with sparse well networks. We apply gravity as an independent constraint to quantify groundwater storage dynamics and evaluate recharge ...

Role of the d⁎(2380) dibaryon in NN interaction

open access: yesPhysics Letters B, 2020
It is demonstrated for the first time that the dibaryon resonance d⁎(2380) discovered reliably in the numerous experiments at the WASA@COSY facility (Jülich FZ) determines almost completely (when supplemented with the peripheral one-pion exchange) NN ...
