Acta Crystallographica Section D, EarlyView.We have studied the copper sites in three cryogenic electron‐microscopy structures of particulate methane monooxygenase with quantum refinement. We show that the CuA, CuC and CuD sites are correctly modelled and that the CuB site is mononuclear in all structures, whereas we find no support for copper in the suggested trinuclear active site or two sites

Noûs, EarlyView.ABSTRACT How should we understand the duration of a pleasant or unpleasant sensation, insofar as its duration modulates how good or bad the experience is overall? Given that we seem able to distinguish between subjective and objective duration and that how well or badly someone's life goes is naturally thought of as something to be assessed from her ...

Wind Energy, Volume 29, Issue 2, February 2026.ABSTRACT This paper provides improvements to a previously presented simple, accurate, lower order analytical model for predicting the performance of horizontal‐axis shrouded turbines for a wide range of shroud airfoil shapes varying in length, camber, and thickness. The new, extended model incorporates explicit quantitative predictions of those effects

Fluid Flow Equations for Rotordynamic Flows in Seals and Leakage Paths [PDF]
, 2001 Fluid-induced rotordynamic forces produced by the fluid in an annular seal or in the leakage passage surrounding the shroud of a pump or turbine, are known to contribute substantially to the potential excitation forces acting on the rotor.

Methods for Cleaning Apollo Passive Seismic Data
Earth and Space Science, Volume 12, Issue 12, December 2025.Abstract Apollo passive seismic data provide a unique resource for studying the lunar interior structure. However, the raw data are frequently contaminated by various artifacts, either related to the seismic sensors and the acquisition system or to issues during data transmission to the Earth.
