Background: The accuracy and the reproducibility of radiotherapy can be provided by using immobilization devices such as thermoplastic masks. In head and neck cancer radiotherapy, the patients are mostly immobilized by using thermoplastic masks. In this study, the effect of the thermoplastic mask to the surface and buildup region doses was investigated by using Markus parallel plate ion chamber...
Back ground & Aims: In the edentulous patients some authors suggest to leave dentures in when ventilating with bag-mask. In this research, we suggest a more efficient method. Materials & Methods: In the prospective blind randomized clinical trial we included 200 patients (age≥55) into two groups. After induction of anesthesia in all groups, in the group I, we placed folded gauze in each bucca...
Reverse subdivision aims at constructing a coarser representation of an object given by a fine polygon mesh. In this paper, we first derive a mask for reverse Loop subdivision that can be applied to both regular and extraordinary vertices. The mask is parameterized, and thus can also be used in reversing variants of Loop subdivision, such as those proposed by Warren and Litke. We apply this mas...
Anticipating future events is an important prerequisite towards intelligent behavior. Video forecasting has been studied as a proxy task towards this goal. Recent work has shown that to predict semantic segmentation of future frames, forecasting at the semantic level is more effective than forecasting RGB frames and then segmenting these. In this paper we consider the more challenging problem o...
Since the release of COVID-19 epidemic in late December 2020, recommendations issued for personal protection by the World Health Organization and National Health Organizations around the world. The most prominent of which has the use of masks to prevent the spread of the virus. Despite the importance of this solution, many people still resist using the mask. Therefore, this study, by emphasizin...

Edgar Allan Poe’s tales offer a variety of instances linked to the analysis of human nature and the processes it goes through during the stories. Most of them treat about the destruction of the self as the narrator finds himself confronted with the darkness that gradually will come to annihilate reason and any sensible thinking. The protagonist witnesses not only the darkness inside, but also t...
The nature of audio-visual interactions is poorly understood for meaningful objects. These interactions would be indirect through semantic memory according to the amodal nature of knowledge, whereas these interactions would be direct according to the modal nature of knowledge. This question, central for both memory and multisensory frameworks, was assessed using a cross-modal priming paradigm f...
The conceptual and empirical links between authentic leadership and follower attitudes, behaviors, and performance outcomes have not been fully developed. Although we have a number of articles developing the theory of authentic leadership and testing propositions that will appear in a forthcoming special issue of The Leadership Quarterly (Vol. 16, Issue 3, 2005), the focus of this article is to...
A novel technique of unmasking to repair the degradation in sources separated by spectrogram masking is proposed. Our approach is based on explicit knowledge of the musical audio at note level from a score-audio alignment, which we termed Informed Source Separation (ISS). Such knowledge allows the spectrogram energy to be decomposed into note-based models. We assume that a spectrogram mask for ...
