Mutagenic Survey of Key Residues of NifB Involved in Radical SAM‐Dependent Nitrogenase Cofactor Assembly

open access: yesChemBioChem, Volume 27, Issue 11, 15 June 2026.
NifB uses an RS–K1–K2 triad to assemble the L‐cluster, a [Fe8S9C] precursor of the nitrogenase cofactor. The RS module cleaves SAM to form the 5′‐dA radical, K1 serves structural/SAM‐sensing roles, and K2 drives radical‐dependent fusion with K1. SAM‐anchoring residues link SAM binding to cluster fusion, while termini and surface residues regulate ...

Evaluation Method and Impact of Clean Energy on the Ecotourism Competitiveness of Townships

open access: yesEngineering Reports, Volume 8, Issue 5, May 2026.
This study develops an integrated evaluation framework to analyse the impact of clean energy adoption on the ecotourism competitiveness of rural townships. By applying the fuzzy Delphi method (FDM), analytic network process (ANP) and DEMATEL, the research identifies and prioritizes key indicators linking clean energy, sustainability and tourism ...

Load‐Bearing Characteristics of SLA‐Fabricated Octahedral Porous Structures

open access: yesStrain, Volume 62, Issue 2, April 2026.
A combined experimental–numerical framework was developed to evaluate SLA–fabricated octahedral and pillar–reinforced lattice structures under compression, shear, and torsion. Small increases in infill density produced nonlinear gains in stiffness and strength, reaching a 255% rise in elastic modulus at low porosity. Pillar reinforcement enhanced shear

Statistical foundations of ecological rationality

open access: yesEconomics: Journal Articles, 2020
If we reassess the rationality question under the assumption that the uncertainty of the natural world is largely unquantifiable, where do we end up? In this article the author argues that we arrive at a statistical, normative, and cognitive theory of ...
