Phase-dependent spectra in a driven two-level atom

We propose a method to observe phase-dependent spectra in resonance fluorescence, employing a two-level atom driven by a strong coherent field and a weak, amplitude-fluctuating field. The spectra are similar to those which occur in a squeezed vacuum, but avoid the problem of achieving squeezing over a $4\pi$ solid angle. The system shows other interesting features, such as pronounced gain without population inversion.Comment: 4 pages and 4 figures. Submitted to Phys. Rev. Let

Primary follicular lymphoma of the duodenum

La localisation duodénale des lymphomes folliculaires est considérée comme rare, mais l'incidence de ces tumeurs est en augmentation. Nous rapportons une observation de lymphome primitif du duodénum, montrant la similitude des données endoscopiqucs avec celles de la papulose lymphomateuse des lymphomes du manteau. Les techniques immunohistochimiques et cytogénétiques aident à différencier ces deux tumeurs. Il est essentiel de les différencier car leur pronostic et les modalités de traitement sont différents

International Society of Urological Pathology (ISUP) Consensus Conference on handling and staging of radical prostatectomy specimens

The 2009 International Society of Urological Pathology (ISUP) consensus conference on handling and staging of radical prostatectomy specimens issued recommendations for standardization of pathology reporting of radical prostatectomy specimens. The conference addressed specimen handling, T2 substaging, prostate cancer volume, extraprostatic extension, lymphovascular invasion, seminal vesicle invasion, lymph node metastases and surgical margins. This review summarizes the conclusions and recommendations resulting from the consensus process. (C) 2013 Elsevier Masson SAS. All rights reserved.33315516
