Doppler evaluation of endometrial polyps
The Egyptian Journal of Radiology and Nuclear Medicine, 2018 Introduction: Endometrial polyps are a common cause of abnormal uterine bleeding. Ultrasound is the most accepted investigation to evaluate them. However, the diagnosis can be difficult and even missed on transabdominal and grayscale imaging.

Redistribution of light frequency by multiple scattering in a resonant atomic vapor
, 2015 The propagation of light in a resonant atomic vapor can \textit{a priori} be thought of as a multiple scattering process, in which each scattering event redistributes both the direction and the frequency of the photons.

Two-photon transitions driven by a combination of diode and femtosecond lasers
, 2012 We report on the combined action of a cw diode laser and a train of ultrashort pulses when each of them drives one step of the 5S-5P-5D two-photon transition in rubidium vapor.
