Cigarette Smoke‐Induced Alveolar Macrophage Senescence via GEM/SIRT3‐Mediated Mitochondrial Dysfunction

Advanced Science, EarlyView.
Cigarette smoke accelerates the aging of immune cells in the lung. By combining human single‐cell sequencing, cell culture, and mouse models, the authors show that the protein GEM drives mitochondrial damage and senescence in alveolar macrophages by suppressing SIRT3.

Adiabatic second-harmonic generation

Optics Letters, 2016
Adiabatic three-wave mixing processes enable broadband, efficient, and robust frequency conversion by slowly varying the phase mismatch between the interacting waves along the interaction region. Up until now, this method was mainly used in the case in which one of the waves was undepleted.

Second-harmonic Generated Holograms

Nonlinear Optics: Materials, Fundamentals and Applications, 2000
Second-harmonic generated holograms result from the second-harmonic crosscorrelation in a thin crystal of the optical field diffused by an object with a reference field. The SH field reconstructs a virtual holographic image in real time.

Second-harmonic generation in second-harmonic fiber Bragg gratings

Applied Optics, 1996
We consider the production of second-harmonic light in gratings resonant with the generated field, through a Green's function approach. We recover some standard results and obtain new limits for the uniform grating case. With the extension to nonuniform gratings, we find the Green's function for the second harmonic in a grating with an arbitrary phase ...

Ultrafast Adiabatic Second Harmonic Generation

Conference on Lasers and Electro-Optics, 2017
We introduce a generalization of the adiabatic frequency conversion method for an efficient conversion of ultrashort pulses in the full nonlinear regime. Our analysis takes into account dispersion as well as two-photon processes and Kerr effect, allowing complete analysis of any three waves with arbitrary phase mismatched design and any nonlinear ...
