ActiveRemediation: The Search for Lead Pipes in Flint, Michigan

open access: yes, 2018
We detail our ongoing work in Flint, Michigan to detect pipes made of lead and other hazardous metals. After elevated levels of lead were detected in residents' drinking water, followed by an increase in blood lead levels in area children, the state and ...

From p+p to Pb+Pb collisions : wounded nucleon versus statistical models [PDF]

open access: yes, 2013
System size dependence of hadron production properties is discussed within the Wounded Nucleon Model and the Statistical Model in the grand canonical, canonical and micro-canonical formulations.

Four upland cotton germplasm lines with improved fiber quality

open access: yesJournal of Plant Registrations, Volume 20, Issue 2, May/August 2026.
Abstract Yarns from all fibers traditionally were produced by aligning the fibers and adding twist. That technique was mechanized over time and today is referred to as ring spinning. About 1970, open‐end spinning technology was introduced that offers increased speed of production while ring offers flexibility in size and quality of yarn. More recently,

Reductions of Gauss-Codazzi equations

open access: yes, 2016
We prove that conformally parametrized surfaces in Euclidean space $\Rcubec$ of curvature $c$ admit a symmetry reduction of their Gauss-Codazzi equations whose general solution is expressed with the sixth Painlev\'e function.

Machine Learning–Assisted Bio‐Interfacial Engineering Resolves Structural–Functional Conflicts in Nanocomposites

open access: yesAdvanced Materials, Volume 38, Issue 24, 27 April 2026.
A machine learning‐guided bio‐interfacial design strategy resolves the long‐standing strength–toughness–functionality trade‐off in nanocomposites. By efficiently mapping high‐performance regions in the composition–processing space, the approach delivers hierarchically entangled, nanosheet‐pinned architectures that combine mechanical robustness ...

Risk Aversion and Economic Policy Uncertainty Impacts on Investor Attention: Evidence From International Stock Markets Indices

open access: yesInternational Journal of Finance &Economics, Volume 31, Issue 2, Page 2878-2898, April 2026.
ABSTRACT This paper examines the relationship between economic policy uncertainty, risk aversion, and investors' attention for 15 equity indices across Asia, Europe, and North America. Our empirical results indicate that both risk aversion and economic uncertainty significantly increase the Google Search Volume across all equity indices.

Spin‐contrast‐variation small‐angle neutron scattering study of fully and partially swollen silica‐filled rubber

open access: yesJournal of Applied Crystallography, Volume 59, Issue 2, Page 492-512, April 2026.
We have elucidated the polymer adsorption layer structure in filler–rubber systems by conducting spin‐contrast‐variation small‐angle neutron scattering on partially and fully swollen filler–rubber samples with and without a silane coupling agent.We have elucidated the polymer adsorption layer structure in filler–rubber systems by conducting spin ...

Application of near infrared spectroscopy in cotton fiber micronaire measurement

open access: yesInformation Processing in Agriculture, 2016
The term “micronaire” describes an important cotton fiber property by characterizing both the fiber maturity and fineness. In practice, micronaire is regularly measured in laboratories with the well established high volume instrumentation (HVI™) protocol.

From recognition to response: integrated signaling pathways determining pollen acceptance and rejection in Brassicaceae

open access: yesNew Phytologist, Volume 250, Issue 2, Page 788-798, April 2026.
Summary Generation of competent offspring is vital for the prosperity of flowering plants. The pistil not only functions as a conduit for pollen tubes to grow to the ovary but also provides a selective venue for facilitating the growth of compatible pollen tubes and discouraging invaders and incompatible pollen.

Genforeningen – hvad nu hvis?

open access: yesRADAR - Historiedidaktisk tidsskrift, 2023
Genforeningen er på historiefagets kanonliste. I anledningen af 100-året vil de fleste klasser arbejde med emnet i 2020. I forløbet fra 1840’erne, der kulminerede med Genforeningen, var der en række afgørende situationer, hvor personer med magt kunne have truffet andre beslutninger – og historien havde udviklet sig helt anderledes.
