Discontinuities that arise when designing for educational improvement at state scale

Frontiers in Education
This paper explores the tensions—or discontinuities—that arise when designing for educational improvement at scale through research-practice partnerships (RPPs).

Gravitational Lensing by Cold Dark Matter Catastrophes

, 1999
Intrinsically cold particle dark matter inevitably creates halos with sharp discontinuities in projected surface density caused by the projection of fold catastrophes onto the sky.

Cathodic Cage Plasma Deposition of Nanostructured Cu–Fe–Se Coatings on Poly(methyl Methacrylate)

Advanced Engineering Materials, EarlyView.
Nanostructured Cu–Fe–Se coatings are deposited on PMMA by a modified cathodic cage plasma process, enabling low‐temperature deposition on polymer substrates. A transition from discontinuous to compact morphology is observed with temperature, with optimal properties at 200°C, where improved CuFeSe2‐type bonding, lowest sheet resistance, and favorable ...

Aligning Firm Capabilities and Business Environment in a Managerial Context: Evidence from the 2016 Presidential Election and Dodd-Frank Rollback

American Business Review
Studies examining firm capabilities under abrupt discontinuities are scarce. To contribute to this literature, we focus on the effect of matching firm capabilities to business environments.

Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids

Advanced Functional Materials, EarlyView.
This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.

La frontière, interface des trafics dans le Triangle d’or

L'Espace Politique, 2015
From opiates to amphetamine-type stimulants, drug production and drug trafficking have evolved over a few decades in the so-called Golden Triangle, in the heart of the Indochinese peninsula’s fan-shaped highlands.

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

La frontière et son double. Un modèle à partir de l’expérience européenne

Belgeo, 2013
From theoretical proposals and study of perceptions of boundaries and discontinuities in Europe by European and by those wishing to enter, the author proposes a model double border where local enclaves appear for compensating political boundaries ...

Transport Theorem for Spaces and Subspaces of Arbitrary Dimensions

Mathematics, 2020
Using the apparatus of traditional differential geometry, the transport theorem is derived for the general case of a M-dimensional domain moving in a N-dimensional space, M ≤ N .
