We consider the classical problem of the stick-slip dynamics observed when peeling a roller adhesive tape at a constant velocity. From fast imaging recordings, we extract the dependence of the stick and slip phase durations on the imposed peeling velocity and peeled ribbon length. Predictions of Maugis and Barquins [in Adhesion 12, edited by K. W. Allen, Elsevier ASP, London, 1988, pp. 205-222]...

Peeling skin syndrome (PSS) is a very rare keratinization disorder, characterized by spontaneous exfoliation of the stratum corneum. Herein, we report a case of non-inflammatory (type A) PSS.

Interest in inverse dynamical, spectral and scattering problems for differential equations on graphs is motivated by possible applications to nano-electronics and quantum waveguides and by a variety of other classical and quantum applications. Recently a new effective leaf peeling method has been proposed by S. Avdonin and P. Kurasov [3] for solving inverse problems on trees (graphs without cyc...

Overview The demand for facial skin rejuvenation has seen recent, unprecedented growth. As people have become more aware about their cosmetic appearance, there has been a greater demand for newer technologies for treating aged and actinically damaged facial skin. Despite various methods available, the use of chemical peeling agents continues to be the gold standard. Chemical peeling is a proced...

Optical coherence tomography (OCT) has emerged as a powerful diagnostic aid in disorders of the vitreoretinal juncture. The purpose of this study is to determine whether OCT can be used as an additional tool for evaluating an architecture including the thickened area, and the identifiable edge of a macular epiretinal membrane (ERM), and helping us to dissect the ERM from the retinal surface mor...

Phototoxic maculopathy caused by endoillumination during macular surgery is uncommon. Previously identified risk factors have included intensity of the light source, proximity to the retinal surface, and length of exposure. In the era of indocyanine green (ICG)-assisted internal limiting membrane (ILM) peeling, the use of ICG, and the technique of ILM peeling may both contribute to subsequent p...

The stick-slip dynamics of the peeling of an adhesive tape is characterized by bifurcations that have been experimentally well studied. In this work, we investigate the time scale in which the the stick-slips happen leading to the bifurcations. This is fundamental to understanding the triboluminescence and acoustic emissions associated with the bifurcations. We establish a relationship between ...

INTRODUCTION Brilliant blue G is a new dye used for staining the internal limiting membrane to ease its peeling in cases like a macular hole. CASES Three patients presented with full-thickness idiopathic macular hole. They underwent pars planavitrectomy, Brilliant Blue G (BBG) stained internal limiting membrane peeling and fluid gas exchange. OBSERVATIONS Postoperatively,the macular hole cl...
