Spontaneous Otorrhagia after Laparoscopic Pelvic Surgery: A Report of Two Cases.

Spontaneous otorrhagia following laparoscopic pelvic surgery is a complication that is rarely reported and incompletely understood. Few case reports have described this phenomenon, though its true incidence is unknown. It has been hypothesized that a combination of extreme patient positioning and abdominal insufflation is the contributing factor.

Using wavelets to analyze AFM images of thin films: surface micelles and supported lipid bilayers.

This paper presents micro- and nanoanalysis of thin films based on images obtained by atomic force microscopy (AFM). The analysis exploits the discrete wavelet transform and the resulting wavelet spectrum to study surface features. It is demonstrated that the wavelet technique can characterize micro- and nanosurface features and distinguish between similar surface structures.
