Hypofractionated radiotherapy for the adjuvant treatment of breast cancer has been standard practice in UK since 2009. Ten-year follow-up data from START-B have confirmed efficacy 40 Gy 15 fractions, with reduced toxicity when compared previous 50 25 fractions [[1]Haviland J.S. Owen J.R. Dewar J.A. Agrawal R.K.

purpose – the purpose of this paper is to present a study of knowledge management understanding and usage in small and medium knowledge-intensive enterprises. design/methodology/approach – the study has taken an interpretative approach, using two knowledge-intensive south isfahan (iran) companies as case studies, both of which are characterized by the need to process and use knowledge on a dail...

In this research paper, ANFIS modeling and validation of Vestas 660 kW wind turbine based on actual data obtained from Eoun-Ebn-Ali wind farm in Tabriz, Iran, and FAST is performed. The turbine modeling is performed by deriving the non-linear dynamic equations of different subsystems. Then, the model parameters are identified to match the actual response. ANFIS is an artificial intelligent tech...

The Fast Marching Method (FMM) is an efficient technique to numerically solve the eikonal equation. The parallelisation of the FMM is not easy because of its intrinsic sequential nature. In this paper we propose a novel approach to parallelise the FMM which is not based on a classic domain-decomposition procedure. Compared to other techniques in the field, our method is much simpler to implemen...

We present a randomized subexponential time, polynomial space parameterized algorithm for the k-Weighted Feedback Arc Set in Tournaments (k-FAST) problem. We also show that our algorithm can be derandomized by slightly increasing the running time. To derandomize our algorithm we construct a new kind of universal hash functions, that we coin universal coloring families. For integers m, k and r, ...

Background: Despite many studies showing a correlation between fast food consumption and non-alcoholic fatty liver disease (NAFLD) known as the silent death, few studies have investigated the effects of different types of fast foods on this disease. This research aimed to evaluate the effect of consuming different types of fast foods on non-alcoholic fatty liver disease. Materials and Methods:...

objective(s): previous studies showed that skeletal muscle microcirculation was reduced in chronic heart failure. the aim of this study was to investigate the effects of endurance training on capillary and arteriolar density of fast and slow twitch muscles in rats with chronic heart failure. materials and methods: four weeks after surgeries (left anterior descending (lad) artery occlusion), chr...
