BeppoSAXLECS background subtraction techniques [PDF]

open access: yesAstronomy and Astrophysics Supplement Series, 1999
We present 3 methods for the subtraction of non-cosmic and unresolved cosmic backgrounds observed by the Low-Energy Concentrator Spectrometer (LECS) on-board BeppoSAX. Removal of these backgrounds allows a more accurate modeling of the spectral data from point and small-scale extended sources.

Resonance-aware subtraction in the dipole method

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We present a technique for infrared subtraction in next-to-leading order QCD calculations that preserves the virtuality of resonant propagators. The approach is based on the pseudo-dipole subtraction method proposed by Catani and Seymour in the context ...

High-Stringency Subtraction for the Identification of Differentially Regulated cDNA Clones

open access: yesBioTechniques, 1997
The technique of high-stringency subtraction described here facilitates subtractive hybridizations between directional cDNA libraries constructed in λ ZAP® II cloning vectors and represents an improvement on earlier methods for the subtraction of entire ...

A comparison of subtraction MRI with the standard contrast-enhanced imaging in Perthes’ disease

open access: yesJournal of Children's Orthopaedics, 2019
Purpose Perthes’ disease (PD) results from loss of blood supply to the hip and can progress to femoral head deformity. MRI in the early course of the disease can provide data on the initial extent of infarct.
