Natural time analysis of critical phenomena.
A quantity exists by which one can identify the approach of a dynamical system to the state of criticality, which is hard to identify otherwise. This quantity is the variance κ(1)(≡<χ(2)> - <χ>(2)) of natural time χ, where = Σp(k)f(χ(k)) and p(k) is the normalized energy released during the kth event of which the natural time is defined as χ(k) = k/N and N stands for the total number of ...

چکیده گفتگوگری باختین نظریه ای است که به تفاوت ها احترام گذاشته و گفتگو را ارج می نهد. رشته های مختلف علوم انسانی همواره از این نظریه بهره جسته اند. با وجود این تنها مطالعات اندکی در زمینه تجزیه و تحلیل نقادانه کلام به نظریه گفتگوگری پرداخته اند. پنداشت تحقیق حاضر بر آن است که احترام به حقوق دیگران از طریق فراهم آوردن شرایط یکسان برای بیان نظریات مختلف یکی از مهمترین مشترکات تحلیل انتقادی گفتم...
15 صفحه اولParity-time-symmetric quantum critical phenomena
Synthetic non-conservative systems with parity-time (PT) symmetric gain-loss structures can exhibit unusual spontaneous symmetry breaking that accompanies spectral singularity. Recent studies on PT symmetry in optics and weakly interacting open quantum systems have revealed intriguing physical properties, yet many-body correlations still play no role. Here by extending the idea of PT symmetry t...
متن کاملReconstruction and rendering of time varying natural phenomena
While computer performance increases and computer generated images get ever more realistic, the need for modeling computer graphics content is becoming stronger. To achieve photo-realism detailed scenes have to be modeled often with a significant amount of manual labour. Interdisciplinary research combining the fields of Computer Graphics, Computer Vision and Scientific Computing has led to the...
متن کاملBayesian inference in the scaling analysis of critical phenomena.
To determine the universality class of critical phenomena, we propose a method of statistical inference in the scaling analysis of critical phenomena. The method is based on Bayesian statistics, most specifically, the Gaussian process regression. It assumes only the smoothness of a scaling function, and it does not need a form. We demonstrate this method for the finite-size scaling analysis of ...
