TL;DR: FDG PET/CT uptake parameters are predictors of patients’ outcome and can potentially identify patients with higher risk of treatment failure that could benefit from more aggressive approaches.
Abstract: Purpose
The aim of this study was to evaluate the predictive role of pre-therapy fluorodeoxyglucose (FDG) uptake parameters of primary tumour in head and neck cancer (HNC) patients undergoing intensity-modulated radiotherapy (IMRT) with simultaneous integrated boost (SIB) on FDG-positive volume—positron emission tomography (PET) gross tumour volume (PET-GTV)

TL;DR: In this paper, an algorithm describing occupant clothing changes in response to thermal comfort was incorporated into a computer model for predicting the thermal conditions and resulting energy consumption of an office space, and the results illustrate the effect that consideration of occupant behaviour can have on simulation output, suggesting that recommendations for building operation based on the assumption of passive occupants may be sub-optimal.

TL;DR: The nearly non-luminescent ruthenium(II)-terpyridine chromophore, functionalized with an uncoordinated terpyridine fragment, 2, undergoes Zn-II-induced association leading to a luminescent rod-like 2 : Zn2+ : 2 species with a luminecence enhancement factor, EF 10.

TL;DR: It is proposed that the expression and activation of DEP-1/PTPη is required for somatostatin inhibition of glioma proliferation and basic fibroblast growth factor-dependent MEK phosphorylation was not affected.

TL;DR: The calculations show that inphantom side-scatter equilibrium is a major factor for the contribution from the direct component which usually dominates the output of a beam.
Abstract: A major task in commissioning an electron accelerator is to measure relative output factors versus cutout size (i.e., cutout factors) for various electron beam energies and applicator sizes. We use the BEAM Monte Carlo code [Med Phys. 22, 503-524 (1995)] to stimulate clinical electron beams and to calculate the relative output factors for square cutouts. Calculations are performed for a Siemens MD2 linear accelerator with beam energies, 6, 9, 11, and 13 MeV. The calculated cutout factors for square cutouts in 10 X 10 cm2, 15 X 15 cm2, and 20 X 20 cm2 applicators at SSDs of 100 and 115 cm agree with the measurements made using a silicon diode within about 1% except for the smallest cutouts at SSD= 115 cm where they agree within 0.015. The details of each component of the dose, such as the dose from particles scattered off the jaws and the applicator, the dose from contaminant photons, the dose from direct electrons, etc., are also analyzed. The calculations show that inphantom side-scatter equilibrium is a major factor for the contribution from the direct component which usually dominates the output of a beam. It takes about 6 h of CPU time on a Pentium Pro 200 MHz computer to simulate an accelerator and additional 2 h to calculate the relative output factor for each cutout with a statistical uncertainty of 1%.
