Vacuum ultraviolet light production by nuclear irradiation of liquid and gaseous xenon [PDF]
Recent Los Alamos investigations suggest that a liquefied noble element may be the long-sought medium for a nuclear-excited laser or flashlamp. Research is needed to confirm this finding and to provide a basis for design and application studies ...

Concentration, temperature, and density in a hydrogen-air flame by excimer-induced Raman scattering [PDF]
Single-pulse, vibrational Raman scattering (VRS) is an attractive laser diagnostic for the study of supersonic hydrogen-air combustion. The VRS technique gives a complete thermodynamic description of the gas mixture at a point in the reacting flow ...

The Provenance of Silver in the Viking‐Age Hoard From Bedale, North Yorkshire
Archaeometry, EarlyView.ABSTRACT The acquisition of silver was a key motive propelling the Viking expansion out of Scandinavia; identifying the sources of Viking silver during the early part of the Viking Age can provide critical insights into the relative significance of western European and eastern, Islamic wealth in the Viking expansion.

RioM‐1: A New Calcite Reference Material for U‐Pb LA‐ICP‐MS Geochronology
Geostandards and Geoanalytical Research, EarlyView.Key Points RioM‐1 calcite was characterised for trace elements, U‐Pb geochronology, Sr and O isotopes using ID‐TIMS, LA‐ICP‐MS and SIMS. U‐Pb dates from ID‐TIMS and LA‐ICP‐MS across several independent laboratories returned identical results within uncertainty.

International Journal of Dermatology, EarlyView.ABSTRACT Prurigo nodularis (PN) is a chronic, intensely pruritic skin disorder characterized by hyperkeratotic nodules and a debilitating itch–scratch cycle. Conventional therapies have limited efficacy and safety issues, while biologics have recently emerged as a promising alternative.
