Hi Everyone,

I am looking forward to seeing you at #NetSci! I’ve attached the latest version of the paper I will be presenting there. It focuses on how homophily can vary across different social scales and how this variability can affect the percolation properties of networks. We also explore the implications of imperfect vaccination as a fascinating case within this framework.

If you are interested ,I have two presentations scheduled: one on Tuesday at 15:00 during the Network Geometry satellite session and another the next day in the main conference, where I’ll be speaking in the multilayer networks parallel session at 17:30.

Looking forward to your feedback and seeing you there!

Vaccines have saved 154 million lives and counting, Nature reported in April. And vaccines are reaching new heights: the human papillomavirus (HPV) vaccine, for example, seems to prevent almost all cervical cancers.

Comparative evaluation of behavioral epidemic models using COVID-19 data

Modeling the interplay between human behavior and infectious disease transmission remains one of the key challenges in Epidemiology. In this study, we evaluate the performance of three mechanistic behavioral epidemic models designed to address this issue. We compare data-driven and analytical approaches across the first COVID-19 wave, spanning nine diverse locations and two modeling tasks. While the optimal model may vary depending on factors such as data availability and geography, our findings show that approaches explicitly modeling behavioral feedback mechanisms often outperform data-driven approaches, even when considering data quality and the increased numbers of free parameters of these models.

Today, the FDA approved a new form of PrEP, lenacapavir, a twice-a-year injectable. PrEP, or Pre-exposure prophylaxis, is 99% effective in preventing HIV.

The drug could change the course of the AIDS epidemic. But the Trump administration has gutted the programs that might have paid for it in low-income countries.

What Is a Macrostate? Subjective Observations and Objective Dynamics

We consider the question of whether thermodynamic macrostates are objective consequences of dynamics, or subjective reflections of our ignorance of a physical system. We argue that they are both; more specifically, that the set of macrostates forms the unique maximal partition of phase space which (1) is consistent with our observations (a subjective fact about our ability to observe the system) and (2) obeys a Markov process (an objective fact about the system’s dynamics). We review the ideas of computational mechanics, an information-theoretic method for finding optimal causal models of stochastic processes, and argue that macrostates coincide with the “causal states” of computational mechanics. Defining a set of macrostates thus consists of an inductive process where we start with a given set of observables, and then refine our partition of phase space until we reach a set of states which predict their own future, i.e. which are Markovian. Macrostates arrived at in this way are provably optimal statistical predictors of the future values of our observables.
