PurposeTo compare the adverse side effects of fractionated stereotactic photon beam radiotherapy (fSRT) with proton (PBR) in patients uveal melanoma (UM).MethodsA retrospective study investigating 306 UM treated fSRT (N=153) by Rotterdam Ocular Melanoma Study group (ROMS), The Netherlands, between 1999–2014 or PBR at Royal Liverpool University Hospital and Clatterbridge Cancer Centre, Bebington...

Background Patient’s rights are worldwide considerations. Saudi Patient’s Bill of Rights (PBR) which was established in 2006 contained 12 items. Lack of knowledge regarding the Saudi PBR limits its implementation in health facilities. This study aimed to investigate the knowledge of health professions’ students at College of Applied Medical Sciences (CAMS) Riyadh Saudi Arabia regarding the exis...

A miniaturized, small-scale photobioreactor (PBR) known as EOSS2-PBR (Efficient Overproducing Screening System photobioreactor) has been developed to characterize microalgal growth under controlled conditions. As with similar systems, allows the screening of either culture conditions or species performance, but it is also specially designed provide high levels light absorption control in volume...

In this paper we introduce a new drawing style of a plane graph G, called proper box rectangular (PBR) drawing. It is deened to be a drawing of G such that every vertex is drawn as a rectangle, called a box, each edge is drawn as either a horizontal or a vertical line segment, and each face is drawn as a rectangle. We establish necessary and suucient conditions for G to have a PBR drawing. We a...

Focusing light through scattering media has broad applications in optical imaging, manipulation and therapy. The contrast of the focus can be quantified by peak-to-background intensity ratio (PBR). Here, we theoretically and numerically show that by using a transmission matrix inversion method to achieve focusing, within a limited field of view and under a low noise condition in transmission ma...

Domain-independent planning is a hard combinatorial problem. Taking into account plan quality makes the task even more difficult. This article introduces Planning by Rewriting (PbR), a new paradigm for efficient high-quality domain-independent planning. PbR exploits declarative plan-rewriting rules and efficient local search techniques to transform an easy-to-generate, but possibly suboptimal, ...

Proton beam radiotherapy (PBR) has gained acceptance for the treatment of breast cancer because of unique beam characteristics that allow superior dose distributions with optimal dose to the target and limited collateral damage to adjacent normal tissue, especially to the heart and lungs. To determine the compatibility of breast tissue expanders (TEs) with PBR, we evaluated the structural and d...

Most fMRI studies are based on the detection of a positive BOLD response (PBR). Here, we demonstrate and characterize a robust sustained negative BOLD response (NBR) in the human occipital cortex, triggered by stimulating part of the visual field. The NBR was spatially adjacent to but segregated from the PBR. It depended on the stimulus and thus on the pattern of neuronal activity. The time cou...
