Peel Apart Imaging Systems

Peel and peel again.

AIM To determine if the internal limiting membrane (ILM) was present in the epiretinal membrane (ERM) when we deliberately tried to perform a "double peel" for macular pucker. METHODS Pars-plana vitrectomy and a "double peel" were carried out. The ERM and ILM were stained with Trypan Blue and peeled separately over the same area. The amount of ERM present in ILM specimens and the amount of IL...

"A shadow apart": a symposium on biomedical imaging.

How far apart are classical and quantum systems ? ∗

As is well known, classical systems approximate quantum ones – but how well? We introduce a definition of a “distance” on classical and quantum phase spaces that offers a measure of their separation. Such a distance scale provides a means to measure the quality of approximate solutions to various problems. A few simple applications are discussed. Introduction The purpose of this paper is to int...

APART+: Boosting APART performance via optimistic pipelining of output events

APART (A Posteriori Active ReplicaTion) is a recently proposed active replication protocol specifically tailored for multi-tier data acquisition systems. It ensures consistency of middle-tier sink replicas by means of an a-posteriori synchronization phase based on reconciliation, which is activated only in case replicas react to an input message from the sensors by generating an output event de...

Worlds apart.

The hype that big data will improve healthcare delivery is extraordinary. However, the reality of actually translating big data insights into meaningful healthcare improvements is far more limited. Substantial challenges exist. Variability in data standards and interoperatability prevent efficient linkage of health data. Regulatory and privacy concerns regarding the widespread dissemination and...
