EP-1312: Rectal cancer: using V-MAT with avoidance sectors and avoidance structures to reduce dose to small bowel

The role of neutrophil-to-lymphocyte ratio (NLR) in predicting small bowel toxicity and outcome for rectal cancer patients who received chemoradiotherapy

Background: In this study, we explored the relationship between                  neutrophil-to-lymphocyte ratio (NLR) and grade 3 or higher treatment related small bowel toxicity and treatment outcome of patients with rectal cancer undergoing capecitabine and concurrent intensity modulated radiotherapy (IMRT). Materials and Methods: From the year of 2012 to 2013, 117 rectal cancer patients who ...

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

Small Obstacle Avoidance Sensor

This paper describes a laser ranging sensor that is suitable for applications like small unmanned aerial vehicles. The hardware consists of a diode emitter array and line-scan charge coupled devices. A structured-light technique measures ranges up to 30 meters for 64 field angles in a 90 degree field of view. Operation is eye safe, and the laser wavelength is not visible to night vision goggles...

A counterexample to homophony avoidance*

Pattern avoidance in cyclically ordered structures

We generalize the notion of pattern avoidance to arbitrary functions on ordered sets, and consider specifically three scenarios for permutations: linear, cyclic and hybrid, the first one corresponding to classical permutation avoidance. The cyclic modification allows for circular shifts in the entries. Using two bijections, both ascribable to both Deutsch and Krattenthaler independently, we sin...
