IntroductionImage guidance with gold fiducials improves outcomes of prostate radiotherapy.However, gold produces artefact on CT imaging, interfering with contouring and verification.The purpose of this study was to compare polymer to standard gold fiducials using radiotherapy imaging modalities to assess the visibility and artefact.MethodsTwenty ei
Recently, a new class of macroeconomic business cycle models has emerged.Stochastic dynamic general equilibrium models with rational expectations originally employed by RBC researchers bushranger awning are combined with nominal rigidities and imperfect competition traditionally highlighted by New Keynesian economists.This class of models leads to
The development and study of an optimal control method for the problem of controlling the formation of a group of mobile robots is still a current and popular theme of work.However, there are few works that take into account the issues of time synchronization of 2006 nissan altima radio units in a decentralized group.The motivation for taking up th
Adult stem cells that are tightly regulated by the specific microenvironment, nightstick twm-850xl or the stem cell niche, function to maintain tissue homeostasis and regeneration after damage.This demands the existence of specific niche components that can preserve the stem cell pool in injured tissues and restore the microenvironment for their su
Providing additional damping for system electromechanical oscillations through doubly fed jeff rosenstock buffalo induction generator (DFIG)-based wind turbines is investigated in this study.In this regard, first an objective function is developed to tune the DFIG control gains, aim to maximise the wind farm (WF) contribution to system oscillation
