How is mean-field theory used in the study of complex networks?
Mason Porter, Professor, Department of Mathematics, UCLA.
In terms of using mean-field theories (and related types of approximations) in networks, the most common scenario is when studying a dynamical system on a network. My coauthor James Gleeson and I discuss this at length in our tutorial article on dynamical systems on networks. (See also the preprint version.) You may also want to look at one of our research papers (written along with other coauthors) on mean-field theory.
A dynamical system on a network is a very high-dimensional system, and it is desirable (when possible) to approximate it with a lower-dimensional system (ideally a much lower-dimensional system), which should be much easier to understand and which may even be tractable to analysis (e.g., through approximate closed-form expressions for quantities of interest). Mean-field theories are one approach to trying to do this.

Dynamical Systems on Networks
This volume is a tutorial for the study of dynamical systems on networks. It discusses both methodology and models, including spreading models for social and biological contagions. The authors focus especially on “simple” situations that are analytically…
How much more do we have to learn from studies here and multiple other countries to institute frequent rapid testing for universities and schools?

Good, but Not Great: Taking Stock of a Big Ten University’s Covid Plan
The University of Illinois says an aggressive testing program prevented deaths on and off campus during the last academic year. Now the university is contending with the Delta variant.

@EricTopol @kchangnyt First, does fast frequent testing even work? Here are some data that compare UIUC with "another Big Ten University" with one time a week surveillance testing. Similar in terms of social activity/compliance & background prevalence. 2020…

سرخسها گیاهانی هستند که شکلی هندسی خاصی دارند. اگر قسمتی از آنها را جدا کنید، با کمی دوران و بزرگنمایی میتوانید قسمت دیگری را بازسازی کنید. این ویژگی هندسی فرکتالها است. در مورد هندسه فرکتالی و کاربرد آن در فیزیک نکات جالبی وجود دارد. مثلا چه ربطی بین فرکتالها و پدیدههای بحرانی و علم شبکه وجود دارد؟

Self-testing and vaccination against COVID-19 to minimize school closure
Schools were largely closed in 2020-2021 to counter COVID-19 spread, impacting students’ education and well-being. With highly contagious variants expanding in Europe while vaccine hesitancy persists, safe options to maintain schools open are urgently needed.…

You may have heard that “period three implies chaos“. Here’s a very readable paper about what that means and why it’s true. The paper actually proves a much stronger result, known as Sharkovsky’s theorem, and tells the remarkable story behind it. https://t.co/lL4Egrdroi

مدل آیزینگ سادهترین مدلیه که گذار فاز پیوسته در شرایط تعادل رو نشون میده.
🔻 به دوستانی که با مدل آیزینگ و گذارفاز مربوط به اون زیاد آشنایی ندارن، پیشنهاد میکنم که ۲ جلسه آخر کلاس مکانیک آماری ساسکایند رو ببینند. Lecture 9 and 10
🔻 همینطور پیشنهاد میکنم این نوشته از کوانتا مگزین در مورد ریاضیات پشت تقارنهای گذارفازها رو بخونید.
