Abstract Objective To survey Society of Breast Imaging (SBI) membership on their use abbreviated breast MRI to understand variability in practice patterns. Methods A was developed by the SBI Patient Care and Delivery committee for distribution July August 2021. Eighteen questions queried demographics then practices regarding initial adoption, scheduling finances, protocols, interpretations. Com...

Abstract Objectives Novel point-of-care antigen assays present a promising opportunity for rapid screening of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections. The purpose this study was the clinical assessment new Roche SARS-CoV-2 Rapid Antigen Test. Methods performance Test evaluated vs. reverse transcription polymerase chain reaction (RT-PCR) laboratory-based assay (Se...

Let In(π) denote the number of involutions in the symmetric group Sn which avoid the permutation π. We say that two permutations α, β ∈ Sj may be exchanged if for every n, k, and ordering τ of j + 1, . . . , k, we have In(ατ) = In(βτ). Here we prove that 12 and 21 may be exchanged and that 123 and 321 may be exchanged. The ability to exchange 123 and 321 implies a conjecture of Guibert, thus co...

Hyperspectral imaging can be used in assessing the quality of foods by decomposing the image into constituents such as protein, starch, and water. Observed data can be considered a mixture of underlying characteristic spectra (endmembers), and estimating the constituents and their abundances requires efficient algorithms for spectral unmixing. We present a Bayesian spectral unmixing algorithm e...
