Abstract: A quantum cascade laser (QCL) may include a QCL crystal having an emitting facet, and an active region adjacent the emitting facet, the emitting facet for providing an electromagnetic beam. The QCL may include an optical cavity comprising a mirror being external to the QCL crystal, and for redirecting the electromagnetic beam into the active region of the QCL crystal to provide optical feedback, and a driver circuit for driving the QCL crystal with a constant current. The QCL may include a controller coupled to the optical cavity and for dynamically and autonomously aligning the optical cavity based upon an error signal from the QCL crystal to maintain stable the optical feedback into the active region of the QCL crystal.

Abstract: Disclosed herein are methods and compositions of treating a subject suffering from a wound. In exemplary examples, the method involves elevating MCPIP levels in a subject in need. Elevating MCPIP levels may involve direct administration (e.g. delivery of protein) or indirect administration (e.g. delivery vehicle capable of increasing expression of MCPIP).

Abstract: Methods, systems and apparatus for using nanoparticle seeded short-wavelength discharge generator sources discharge sources, for use with X-ray, XUV and EUV light emissions. Applications can include EUV lithography. Additional embodiments can use the generator sources for Hollow Cathode Plasma Discharge (HCPD) lamps, and dense plasma focus (DPF) devices and other sources. Target streams of gases such as Xe and nanoparticles such as tin, copper, or lithium can be heated with laser type sources to emit nano-droplets therefrom.
