Radiative corrections to $W\gamma\gamma$ production at the LHC [PDF]
Proceedings of RADCOR 2009 - 9th International Symposium on Radiative Corrections (Applications of Quantum Field Theory to Phenomenology) — PoS(RADCOR2009), 2010 Radiative W production at hadron colliders is an important testing ground for the Standard Model. We consider W gamma gamma production which is sensitive to the quartic WW gamma gamma coupling. Furthermore the Standard Model amplitude for this process contains a radiation zero.

Source and LVis based coincidence summing correction in HPGe gamma-ray spectrometry
Nuclear Engineering and Technology, 2022 The activity of gamma-ray emitting nuclides is calculated assuming that each gamma-ray is detected individually; thus, the magnitude of the coincidence summing signal must be considered during activity calculations.

An adaptive gamma correction for image enhancement [PDF]
EURASIP Journal on Image and Video Processing, 2016 بسبب القيود المفروضة على أجهزة التقاط الصور أو وجود بيئة غير مثالية، قد تتدهور جودة الصور الرقمية. على الرغم من التقدم الكبير في علم التصوير، فإن الصور الملتقطة لا تلبي دائمًا توقعات المستخدمين من وجهات النظر الواضحة والمهدئة. تركز معظم الأساليب الحالية بشكل أساسي على التحسين العالمي أو المحلي الذي قد لا يكون مناسبًا لجميع أنواع الصور.
