Experimental Characterization and Constitutive Modeling of the Effect of Prior Inelastic Strain on the Viscoplastic Behavior of AD730 at 700 °C

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.

Effects of Plasma Radiation on the Thomson Scattering Diagnostic Installed on the Large Helical Device [PDF]

, 2007
Recently we modified the Thomson scattering diagnostic (TS) installed on LHD so that DC levels (VDC) of all avalanche photodiodes (APD) used for detecting scattered light can be registered every 1 ms, which enabling us to make validity check on TS data ...

Artificial Intelligence and Machine Learning for Oxygen Reduction Reaction: A Review on Catalyst Discovery and Durability Modeling

Electroanalysis, Volume 38, Issue 9, September 2026.
The oxygen reduction reaction (ORR) at the proton exchange membrane fuel cells (PEMFC) cathode suffers from sluggish kinetics, high platinum loading requirements, and progressive catalyst degradation. This review examines how artificial intelligence (AI) and machine learning (ML) are reshaping the discovery and durability assessment of ORR ...

Generation of X-ray spatiotemporal vortices via nonlinear Thomson scattering

High Power Laser Science and Engineering
High-energy vortex beams with transverse orbital angular momentum (TOAM) have significant applications in many fields. However, generating such beams with well-defined spatiotemporal (ST) field structures at energies beyond extreme ultraviolet is still a

Toward an Improved Understanding of the Antarctic Coastal Zone and Its Contribution to Future Global Sea Level

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...

Controlling the spectral shape of nonlinear Thomson scattering with proper laser chirping

Physical Review Accelerators and Beams, 2016
Effects of nonlinearity in Thomson scattering of a high intensity laser pulse from electrons are analyzed. Analytic expressions for laser pulse shaping in frequency (chirping) are obtained which control spectrum broadening for high laser pulse ...

Experimental observation of nonlinear Thomson scattering [PDF]

, 2006
A century ago, J. J. Thomson showed that the scattering of low-intensity light by electrons was a linear process (i.e., the scattered light frequency was identical to that of the incident light) and that light’s magnetic field played no role.

Infragravity Waves Across a Steep‐Sloping Rough Rocky Seabed on the Inner Shelf

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Observations of infragravity (IG) waves were conducted from June to October 2023 along the rocky shores off China Rock, CA, on the inner shelf at depths of 8–13 m. The study examines inner‐shelf IG wave dynamics over rough, steep rocky shores and compares them with those over smoother, gentler sandy shores and coral reefs. IG energy correlated

Gamma photons and electron-positron pairs from ultra-intense laser-matter interaction: A comparative study of proposed configurations

Matter and Radiation at Extremes, 2019
High-energy γ-photon generation via nonlinear Compton scattering and electron–positron pair creation via the Breit–Wheeler process driven by laser–plasma interaction are modeled, and a number of mechanisms are proposed.
