Effect of Postweld Heat Treatment on Laser‐Welded Duplex Stainless Steel: Crystallographic Patterns and Fatigue Behavior

steel research international, Volume 97, Issue 6, Page 3267-3281, June 2026.
Laser welding of duplex stainless steel disrupts phase balance, promotes nitride precipitation, and reduces fatigue resistance. Postweld heat treatment restores austenite and dissolves nitrides, but the resulting crystallography and phase morphology still impair fatigue performance.

Declining Runoff Sensitivity to Precipitation Following Permafrost Degradation: Insights From Event‐Scale Runoff Response in the Yellow River Source Region

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Frozen ground, including permafrost and seasonally frozen ground (SFG), is a critical element of the cryosphere that strongly regulates hydrological processes in cold regions. It has been debated whether frozen ground degradation will make landscapes more, or less, sensitive to precipitation inputs; either outcome has profound implications for

Development and Deployment of the Smart Active Ionising Radiation at Altitude (SAIRA) Instruments for Space Weather Applications

Space Weather, Volume 24, Issue 6, June 2026.
Abstract This paper introduces the latest generation of airborne ionising radiation monitors, developed at the Surrey Space Centre (SSC) as part of the United Kingdom's (UK's) Space Weather Instrumentation, Measurement, Modeling and Risk (SWIMMR) program.

On the Role of Electron Precipitation in Excess Radiation Doses Measured at Aviation Altitudes

Space Weather, Volume 24, Issue 6, June 2026.
Abstract Radiation from space in the form of galactic cosmic rays (GCRs) generates a persistent background of ionizing radiation in Earth's atmosphere. The dose rate of ionizing radiation due to GCRs increases from sea level to aviation altitudes.

The influence of a cluster‐rooted species on Bossiaea linophylla (Fabaceae) under extremely phosphorus‐impoverished conditions: Phosphorus competition and altered plant–microbe interactions

Functional Ecology, Volume 40, Issue 6, Page 1709-1724, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Phosphorus (P) limitation may intensify plant competition. However, in severely P‐impoverished soils of south‐western Australia, cluster‐rooted Banksia attenuata (Proteaceae) can facilitate P acquisition of neighbouring species by mobilising tightly bound P from soil ...

Lumping Processes of Periodic ARMA Processes

, 2004
In this article various lumping processes are defined for periodic ARMA (PARMA) processes, namely, the forward, the backward and the cyclic lumping processes. The inter-relations between the parameters of these lumping processes are obtained. It is then proved that stationarity of any lumped process implies sta¬tionarity of all other lumped processes ...
