YOLOX-LS: Strong Gravitational Lenses Detection in the DECaLS with Deep Learning

The Astrophysical Journal
The identification of strong gravitational lenses is essential to facilitate many studies in astronomy. The search for strong gravitational lenses has become more challenging because of their scientific value and their rarity. In this paper, we construct

A Strong Gravitational Lens Is Worth a Thousand Dark Matter Halos: Inference on Small-scale Structure Using Sequential Methods

The Astrophysical Journal
Strong gravitational lenses are a singular probe of the Universe’s small-scale structure—they are sensitive to the gravitational effects of low-mass (

Business Participation in Regulation: A Multifocal Perspective on Management Studies

Regulation &Governance, EarlyView.
ABSTRACT This paper conceptualizes how regulation is viewed in management studies in the context of business participation in regulation and explores its implications. We theorize six lenses through which management studies understand regulation: as competitive advantages, boundaries, forums, principles, systems, and cognitive frames.

Lens Modeling of STRIDES Strongly Lensed Quasars Using Neural Posterior Estimation

The Astronomical Journal
Strongly lensed quasars can be used to constrain cosmological parameters through time-delay cosmography. Models of the lens masses are a necessary component of this analysis.
