We report the discovery of a new two-image gravitational lens system, CLASS B2319]051, from the Cosmic Lens All-Sky Survey. Radio imaging with the Very Large Array (VLA) and Multielement Radiolinked Interferometer Network (MERLIN) shows two compact components with a Ñux density ratio of ^5:1, separated by Observations with the Very Long Baseline Array (VLBA) resolve each of the 1A.36. radio com...

A distributionanalysis relating International Standard ISO 15189:2012 process‑...
The global petroleum system is undergoing an “oil transition,” shifting from conventionally produced petroleum to a suite of substitutes for conventional petroleum (SCPs). This paper describes the Regional Optimization Model for Emissions from Oil Substitutes, or ROMEO, which models this oil transition. ROMEO models the dynamics of the transition to substitutes for oil and the environmental imp...
We discuss some aspects of the deformed W-algebras Wq,t[g]. In particular, we derive an explicit formula for the Kac determinant, and discuss the center when t is a primitive k-th root of unity. The relation of the structure of Wq,t[g] to the representation ring of the quantum affine algebra Uq(ĝ), as discovered recently by Frenkel and Reshetikhin, is further elucidated in some examples.
