Dynamic Switchable and Transient DNA Condensates Driven by Aptamer‐Ligand or Ion‐Nucleobase Bridged Complexes

open access: yesSmall, EarlyView.
Switchable or transient formation and dissociation of the phase‐separated DNA microdroplets generated by metal ions or aptamer‐ligand complexes crosslinking Y‐shaped DNA frameworks and dynamically separated by counter ligands eliminating the bridging metal ions or biocatalysts degrading the aptamer‐ligand complexes, are introduced.

Buchanan and the Social Contract: Coordination Failures and the Atrophy of Property Rights

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT James Buchanan advocated that societies should be based on a social contract. He rejected anarchy, seeing it as a “Hobbesian jungle” that calls for government intervention to maintain social order. He also opposed theories of spontaneous order. These views led to debates about the compatibility of Buchanan's works with classical liberalism and

Beggars as Rational Choosers

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT American municipalities increasingly regulate panhandling. That regulation is controversial. The determinants of panhandling activeness are unknown, and it is doubted whether panhandling activity responds rationally to incentives. To shed light on these issues, we collect data on hundreds of panhandlers and the passersby they solicit at ...

Microstructure Characterization of Bending Effects in 304L Stainless Steel Cladded with Low‐Alloy Steel Weld

open access: yessteel research international, EarlyView.
Prebending of 304L/Q345R cladded plates significantly alters the subsequent weld thermal cycle and modifies the local interfacial microstructure. Combined electron backscatter diffraction (EBSD) and microscopy analysis demonstrates that deformation twinning, martensitic transformation, and defect initiation are concentrated at the trimaterial junction,

Influence of Oxygen Contamination on the Genesis of Nonmetallic Inclusions in a Microalloyed Steel

open access: yessteel research international, EarlyView.
Oxygen contamination during melting of steels strongly affects the evolution of nonmetallic inclusions. Controlled remelting experiments, combined with SEM/EDS analysis and thermodynamic simulations, reveal how reoxidation promotes the transformation of alumina‐based inclusions into complex FeO–MnO oxides and other interactions.
