🦠 چرا تست‌های با حساسیت کمتر می‌تونن گزینه‌های بهتری باشن؟

این ویدئو در مورد اینه که چرا «تست‌های سریع آنتی‌ژن» با این‌که سریعتر، ارزون‌تر و با حساسیت «کمتری» نسبت به تست‌های پی‌سی‌آر هستند اما برای غربالگری (و شاید مراقبت) ابزار بهتری به حساب میان! مزایا و معایب تست پی‌سی‌آر و تست سریع آنتی‌ژن چیه؟!

شواهدی روبه‌روشدی نشون میدن که بدن افراد آلوده به کرونا می‌تونه پادتنی بسازه که به بافت‌های بدن آسیب بزنه؛

There's growing evidence that SARS-CoV-2 might cause the body to generate antibodies that attack its own tissues, perhaps explaining why some get so sick or for so long. #LongCovid

"Machine-Learning Mathematical Structures" (by Yang-Hui He): https://arxiv.org/abs/2101.06317

"We review, for a general audience, a variety of recent experiments on extracting structure from machine-learning mathematical data that have been compiled over the years."

What is economic complexity? And how it is helping us understand the economy? More than a decade ago, two papers helped ignite the field.

🎞 The Structure of Complex Networks: Scale-Free and Small-World Random Graphs - Remco van der Hofstad

https://www.aparat.com/v/gryA3

Abstract:
Many phenomena in the real world can be phrased in terms of networks. Examples include the World-Wide Web, social interactions and Internet, but also the interaction patterns between proteins, food webs and citation networks.

Many large-scale networks have, despite their diversity in backgrounds, surprisingly much in common. Many of these networks are small worlds, in the sense that one requires few links to hop between pairs of vertices. Also the variability of the number of connections between elements tends to be enormous, which is related to the scale-free phenomenon.

In this lecture for a broad audience, we describe a few real-world networks and some of their empirical properties. We also describe the effectiveness of abstract network modeling in terms of graphs and how real-world networks can be modeled, as well as how these models help us to give sense to the empirical findings. We continue by discussing some random graph models for real-world networks and their properties, as well as their merits and flaws as network models. We conclude by discussing the implications of some of the empirical findings on information diffusion and competition on such networks.

We assume no prior knowledge in graph theory, probability or otherwise.

Scaling limits: from statistical mechanics to manifolds
September 1-3, 2021

http://www.statslab.cam.ac.uk/james60

This workshop will take James' work as a jumping-off point for an exploration of future research directions in probability. There will be 16 invited talks loosely covering the following themes:

Random growth processes and SPDEs
Yang-Mills measure
Limits of random graphs, random planar maps, and fragmentation processes
Markov chains, interacting particle systems and fluid limits
Diffusion processes and heat kernels.
