An Introduction to Rational Constructivism in Cognitive Development

open access: yesTopics in Cognitive Science, EarlyView.
Abstract Rational constructivism is a contemporary theory of cognitive development. It proposes that children generate, tweak, and radically revise theories, beliefs, and representations by integrating evidence with existing knowledge via probabilistic inferential learning mechanisms.

The Long Shadow of Karl Weierstraß Over the Calculus of Variations

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT At first glance, it appears that the contents of Karl Weierstraß's (1815–1897) lecture courses on the calculus of variations were made available to the public only in the seventh volume of his Mathematische Werke, and thus not until 30 years after his death.

Genomic profiling of Mexican patients with B‐cell precursor acute lymphoblastic leukemia reveals clinically significant somatic and potential germline variants

open access: yesThe Journal of Pathology: Clinical Research, Volume 12, Issue 5, September 2026.
Abstract B‐cell precursor acute lymphoblastic leukemia (preB‐ALL) is characterized by pathogenic variants currently used in precision oncology. However, the mutational landscape of Mexican children with preB‐ALL has not yet been thoroughly explored and defined in terms of the clinical significance.

NHO‐Functionalized Bipyridines: Proton‐Switchable Strongly Electron‐Donating Chelating Ligands

open access: yesChemistryEurope, Volume 4, Issue 9, September 2026.
Decoration with N‐heterocyclic olefins (NHOs) turns 2,2′‐bipyridine into an electron‐rich, proton‐switchable ligand. The switching range is remotely tunable by the NHO backbone and can surpass the donor strength of anionic nitrogen donors. Installing N‐heterocyclic olefins (NHOs) at the 4,4′‐positions converts 2,2′‐bipyridine into a donor‐flexible ...
