Astronomische Nachrichten, EarlyView.ABSTRACT We investigate the effects of a minimal measurable length on neutron stars, within the quantum hadrodynamics (QHD‐I) model modified by the Generalized Uncertainty Principle (GUP). Working in a deformed Poisson algebra framework, we incorporate GUP effects via a time‐invariant transformation of the phase space volume, effectively reducing the ...

Berichte zur Wissenschaftsgeschichte, EarlyView.Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...

ChemBioChem, EarlyView.The study characterizes interactions between DnaB helicase and DnaG primase in Mycobacterium tuberculosis using small‐angle X‐ray scattering, surface plasmon resonance, and cross‐linking. The findings reveal that DnaG forms dimers in solution, which are destabilized upon DnaB binding.

Human flaws and logical tools in engineering
The Canadian Journal of Chemical Engineering, Volume 103, Issue 8, Page 3512-3520, August 2025.Abstract This paper explores the limitations of human cognition, especially in engineering research, emphasizing the need for mathematical models and methods to guide decision‐making and theory validation. While human cognition excels in certain tasks, it is prone to biases that can distort our understanding.

ChemPhysChem, EarlyView.Bi/BiOBr/P25 TiO2 composites are synthesized via a solvothermal method incorporating 1 wt% of a carbon‐based material (graphene oxide [GO], graphene, carbon nanotubes, or buckminsterfullerene). The GO–based composite exhibits the highest photocatalytic NOx removal efficiency (≈22% NO and ≈15% NO2) with these synergetic improvements attributed to ...
