Determining Thresholds for Computer‐Aided Detection for Silicosis—An Analytic Approach

open access: yesAmerican Journal of Industrial Medicine, EarlyView.
ABSTRACT Background Computer‐aided detection (CAD) is emerging as an adjunct to the use of the chest X‐ray (CXR) in screening for pulmonary tuberculosis (TB). CAD for silicosis, a fibrotic lung disease due to silica dust and a strong risk factor for TB, is at an earlier stage of development and, unlike TB, depends on expert human reading for validation.

Copper‐Catalyzed Synthesis of C‐2 Substituted Indolin‐3‐Ones and Indolin‐3‐One [4+2] Cycloadducts Through Azide‐Tethered Iodonium Ylides

open access: yesAsian Journal of Organic Chemistry, EarlyView.
Azide‐tethered iodonium ylides under copper catalysis generate metallocarbenes that undergo intramolecular trapping by the azide moiety and generate a reactive C‐acylimine, effectively coupling two nucleophilic centers. This intermediate can be trapped by a wide range of nucleophiles or 1,3‐dienes producing complex indolin‐3‐ones and ...
