Field‐level crop choice responses to weather‐induced yield shocks in the US Corn Belt

American Journal of Agricultural Economics, Volume 108, Issue 4, Page 1048-1075, August 2026.
Abstract As climate change increases the frequency and severity of extreme heat events, farmers are expected to face greater variability in crop yields. Using 10 million field‐level observations, this study examines how farmers in the US Corn Belt adjust corn–soybean rotation decisions in response to yield shocks largely driven by weather fluctuations.

Style‐Constrained Inverse Design of Microstructures With Tailored Mechanical Properties Using Unconditional Diffusion Models

International Journal for Numerical Methods in Engineering, Volume 127, Issue 13, 15 July 2026.
ABSTRACT Deep generative models, particularly denoising diffusion models, have achieved remarkable success in high‐fidelity generation of architected microstructures with desired properties and styles. However, these recent methods typically rely on conditional training mechanisms that require extensive labeled data.

Detection and Quantification of Two Flatfish Species in the Sylt Outer Reef: Development of a qPCR Assay and Forecast Model Based on eDNA Copies

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
ABSTRACT Assessing fish diversity and abundance is crucial for effective marine conservation and management strategies, particularly in ecologically sensitive areas such as the North Sea. Bottom trawling, one of the most commonly used fishing methods, is facing growing criticism, even for scientific purposes, and has already been banned in ecologically

Further Findings on the Intergenerational Transmission of Alcohol Consumption

Health Economics, Volume 35, Issue 7, Page 1056-1072, July 2026.
ABSTRACT Using 43,817 parent–child pairs from 23 waves of the HILDA Survey, I study the intergenerational transmission of alcohol use within a rational model of trait transmission. Transmission is predominantly same‐sex: the mother–daughter elasticity is 0.10 and the father–son elasticity is 0.09; there is no father–daughter effect.

On Invariants And Homology Of Spaces Of Knots In Arbitrary Manifolds

, 1997
The construction of finite-order knot invariants in R³, based on resolutions of discriminant sets, can be carried out immediately to the case of knots in an arbitrary three-dimensional manifold M (may be non-orientable) and, moreover, to the calculation ...

Mapping the Conformational Landscape of DNA Minicircles Through Atomic Force Microscopy and Shape Space Analysis

Small, Volume 22, Issue 37, 2 July 2026.
An automated framework is presented for quantifying DNA conformational variability from atomic force microscopy (AFM) images. DNA backbones are reduced to spline representations and analyzed using cyclic Procrustes analysis to measure shape similarity across ensembles.

Quantum Invariants of Links and 3-Manifolds with Boundary defined via Virtual Links

, 2023
We introduce new topological quantum invariants of compact oriented 3-manifolds with boundary where the boundary is a disjoint union of two identical surfaces.

Integrated X‐Ray, Gamma Radiation, and Micro‐CT Techniques for Quantitative Wood Characterization

X-Ray Spectrometry, Volume 55, Issue 4, Page 612-628, July/August 2026.
ABSTRACT The present research integrates microcomputed tomography (micro‐CT), x‐ray fluorescence, and gamma‐ray transmission to quantitatively characterize wood species. A total of 22 samples from seven species were analyzed for density (ρ), linear attenuation coefficient (μ), Compton scattering, micro‐CT gray values (GV), porosity, mass attenuation ...

Large scale computations of 3-manifolds invariants

, 2022
La topologie est l'étude des objets à déformation près, sans couper ni coller: l'illustration la plus répandue est sans doute la transformation d'une tasse en donut.

Asymptotics of the Turaev-Viro Invariants and q-hyperbolic Manifolds

, 2023
We study asymptotic properties of the Turaev--Viro invariants and build on their conjecturedconnections to the geometry of 3-manifolds. Our focus is a conjecture of Chen and Yang asserting that the exponential growth rate of the Turaev--Viro invariants ...
