A relativistic Glauber approach to polarization transfer in 4He(\vec{e},e'\vec{p})

open access: yes, 2005
Polarization-transfer components for 4He(\vec{e},e'\vec{p})3H are computed within the relativistic multiple-scattering Glauber approximation (RMSGA). The RMSGA framework adopts relativistic single-particle wave functions and electron-nucleon couplings ...

Blood Vessel Occlusion by the Layperson Audiovisual Assist Tourniquet (LAVA TQ) Compared to the Combat Application Tourniquet: Randomized Controlled Trial

open access: yesWestern Journal of Emergency Medicine, 2023
Introduction: While windlass-rod style tourniquets stop bleeding in limbs when used by skilled responders, they are less successful in the hands of the untrained or not recently trained public.

What factors control superficial lava dome explosivity?

open access: yesScientific Reports, 2015
Dome-forming eruption is a frequent eruptive style and a major hazard on numerous volcanoes worldwide. Lava domes are built by slow extrusion of degassed, viscous magma and may be destroyed by gravitational collapse or explosion.

Effect of Nonsteroidal Anti‐Inflammatory Drugs on Sacroiliac Joint Inflammation, as Seen on Magnetic Resonance Imaging, in Axial Spondyloarthritis

open access: yesArthritis Care &Research, EarlyView.
Objective Imaging evidence of active sacroiliitis is important for diagnosis, classification, and monitoring of axial spondyloarthritis (axSpA). However, there is no consistent guidance on whether patients should temporarily stop nonsteroidal anti‐inflammatory drugs (NSAIDs) before magnetic resonance imaging (MRI).

Icelandic analogs to Martian flood lavas [PDF]

open access: yes, 2004
We report on new field observations from Icelandic lava flows that have the same surface morphology as many Martian flood lava flows. The Martian flood lavas are characterized by a platy-ridged surface morphology whose formation is not well understood ...

Design of Multiphase Compositionally Complex Alloys for Enhanced Hardness at Elevated Temperatures and Machinability: Comparative Study with Inconel 718

open access: yesAdvanced Engineering Materials, EarlyView.
This study compares the mechanical properties of Inconel 718 with two newly developed compositionally complex alloys (CCAs). Inco‐like‐H alloy demonstrates significantly improved wear resistance, surface finish, and hardness, notably at high temperatures. This CCA requires no heat treatment and is well suited for additive manufacturing. Its performance
