Appearance of a new universality class in a competition
Abbas Ali Saberi
16:30- 17:30 , 26 Azar
Ibn Al-Haytham Hall, Physics Department, SBU
During the last decade, it has been shown that the universality in various growth models belonging to the Kardar-Parisi-Zhang (KPZ) class holds beyond the second moment in which the height fluctuations of the (1+1)-D model are connected to the Tracy-Widom (TW) distribution of the Gaussian unitary (and orthogonal) random matrix ensembles (GUE or GOE). In this talk, I will first review the progress in the field and then report on the universality of height fluctuations at the crossing point of two interacting (1+1)-D KPZ interfaces with curved and flat initial conditions. I will show that a new class will show up in the competition. I will also discuss possible applications in nonequilibrium transport and traffic flow.

"From Scratch Machine Learning"
It's a *golden* resource if you learn like I do (by building things from scratch).
Happy learning!

🎤 سمینار عمومی این هفته دانشکده فیزیک
🗣 Ali Faqeeh,
Postdoctoral Fellow, University of Limerick and Indiana University, Bloomington
Title: Modelling and analysis of spreading processes in social platforms
Abstract:
The spreading processes appear on social systems in various forms, from the spread of diseases among civilians to information diffusion and dissemination of ideas, opinions or attitudes. The behavior of each of these phenomena is drawn from a rather complex set of characteristics of the agents (people) in the social system and also impacted by properties of the system such as the connection patterns between the individuals (i.e., the network structure) and the function and characteristics of the dynamics.
In this seminar, I discuss our recent studies on social spreading processes, each of which concerns an interesting aspect of such phenomena. Firstly, I describe our recent analysis of the dissemination of scientific research using the body of the text of more than 230,000 publications. Then I talk about our analysis and modelling of information propagation on Twitter and show how similarity of users’ interests affects the diffusion of twits. Lastly, I introduce a new efficient metric for determining the most influential spreaders for various types of spreading processes that operate on social networks.
