    Notes: Abstract To clarify the mechanical difficulties experienced when performing anterior capsulorhexis in vitrectomized eyes filled with silicone oil. Five anterior lens capsules removed from eyes with a silicone oil history were submitted to light and electron microscopic analysis and then compared to two capsules from eyes with trauma history and seven capsules from eyes without silicone oil or trauma history. Comparable abnormalities of the inner and outer surface of the anterior lens capsule were consistently observed after silicone oil fill of the vitreous cavity or after traumatic impact to the lens: patches of multilayer epithelial cells with interspersed capsule material and connective tissue were observed on the posterior surface of the anterior lens capsule. The development of this anterior subcapsular tissue plaque is obviously influenced not only by the PVR process or by side effects of the surgical procedure but also by the silicone oil tamponade or a trauma history. The plaque can be considered primarily responsible for the increased mechanical resistance of the lens capsule in all eyes with silicone oil/trauma history examined in this study.

    Description: Author(s): Stefano Cusumano, Andrea Mari, and Vittorio Giovannetti We consider many-body quantum systems dissipatively coupled by a cascade network, i.e., a setup in which interactions are mediated by unidirectional environmental modes propagating through a linear optical interferometer. In particular we are interested in the possibility of inducing different effec... [Phys. Rev. A 97, 053811] Published Thu May 10, 2018

    Description: Author(s): Stefano Cusumano, Andrea Mari, and Vittorio Giovannetti In this work we consider quantum cascade networks in which quantum systems are connected through unidirectional channels that can mutually interact giving rise to interference effects. In particular we show how to compute master equations for cascade systems in an arbitrary interferometric configura… [Phys. Rev. A 95, 053838] Published Fri May 12, 2017
