We present a theoretical investigation of the stability properties of semiconductor lasers with strong feedback from dispersive extended cavities. Surprisingly, unstable behavior had been observed experimentally for chirped fiber grating lasers, where the stability of the laser was found to depend upon the orientation of the fiber grating. We reproduce this finding through a linear stability an...

Fidaxomicin is approved for the treatment of adults with Clostridium difficile-associated diarrhea, many of whom have difficulty swallowing an intact tablet. The study objective was to evaluate the stability and recovery of crushed DIFICID(®) (fidaxomicin) 200-mg tablets dispersed in water, applesauce, or Ensure(®) brand liquid nutritional supplement, and to determine the recovery of fidaxomici...

Stability is an important dynamical property of complex systems and underpins a broad range of coherent self-organized behavior. Based on evidence that some neurological disorders correspond to linear instabilities, we hypothesize that stability constrains the brain's electrical activity and influences its structure and physiology. Using a physiologically-based model of brain electrical activit...

Nanofluids as heat transfer fluids have been acquiring popularity ever since their beginning. Therefore, the refrigeration research could not keep itself away from ever-rising horizon of nanofluid applications. On other hand, stability remains critical bottleneck for use. A significant reduction in nanofluids’ performance can derivate instability phenomena. Looking to industrial applications, l...
