Polarization‐Dependence of Nonlinear Optical Effects in Silicon: The Case of Ultrafast Processing

open access: yesAdvanced Physics Research, EarlyView.
The dependence of the input polarization for the nonlinear optical propagation in silicon is investigated theoretically and experimentally. The perturbative regime is examined using pump‐probe shadowgraphy and nonlinear transmission, whereas the case of permanent laser‐induced modifications is addressed using a combination of Raman micro‐spectroscopy ...

SOX6 is expressed in various cell lineages in the developing mouse heart and contributes to proper valvuloseptal development

open access: yesThe Anatomical Record, EarlyView.
Abstract Cells derived from the endocardium, epicardium, cardiac neural crest, and second heart field play a critical role in the formation of the valvuloseptal structures of the heart. Previous studies have shown that the expression of the transcription factor SOX9 in these cell populations is essential in the regulation of this process.
