I am in San Juan Capistrano gaming and hanging out with friends for the long weekend.
My name is Mason Porter. I am a Professor in the Department of Mathematics at UCLA. Previously I was Professor of Nonlinear and Complex Systems in the Mathematical Institute at University of Oxford. I was also a Tutorial Fellow of Somerville College.

2024 Most Valuable Player (MVP) Awards
Major League Baseball has announced the winners of the 2024 Most Valuable Player (MVP) awards. See this page for the complete distribution of votes.
Aaron Judge of the New York Yankees was the unanimous MVP in the American League, with Bobby Witt Jr. of the Kansas City Royal receiving all 2nd-place voters. (I believe that the latter has never happened before.) The American League also had several other very strong candidates in an exceptional field. In the National League, Shohei Ohtani of the Los Angeles Dodgers was the unanimous MVP. This was his third unanimous MVP. Nobody else in Major League Baseball history has won multiple MVP awards unanimously.

2024 Baseball Rookies of the Year
The 2024 Rookies of the Year were announced today. Paul Skenes of the Pirates was the winner of an exceptionally strong rookie class (beating out the two Jacksons) in the National League, and Luis Gil of the Yankees was the winner (barely winning over Colton Cowser of the Orioles) of a much weaker rookie class in the American League.

"Oscillatory Networks: Insights from Piecewise-Linear Modeling"
Another of my papers just appeared in final form. Here are some details.
Title: Oscillatory Networks: Insights from Piecewise-Linear Modeling
Authors: Stephen Coombes, Mustafa Şayli, Rüdiger Thul, Rachel Nicks, Mason A. Porter, and Yi Ming Lai
Dedication: We dedicate this paper to the memory of our dear friend and colleague Yi Ming Lai. Although he began with us on the journey to write this paper, which in part reviews some of his research activity in recent years, sadly he did not end that journey with us. RIP Yi Ming Lai 1988–2022.
Abstract: There is enormous interest—both mathematically and in diverse applications—in understanding the dynamics of coupled-oscillator networks. The real-world motivation of such networks arises from studies of the brain, the heart, ecology, and more. It is common to describe the rich emergent behavior in these systems in terms of complex patterns of network activity that reflect both the connectivity and the nonlinear dynamics of the network components. Such behavior is often organized around phase-locked periodic states and their instabilities. However, the explicit calculation of periodic orbits in nonlinear systems (even in low dimensions) is notoriously hard, so network-level insights often require the numerical construction of some underlying periodic component. In this paper, we review powerful techniques for studying coupled-oscillator networks. We discuss phase reductions, phase–amplitude reductions, and the master stability function for smooth dynamical systems. We then focus, in particular, on the augmentation of these methods to analyze piecewise-linear systems, for which one can readily construct periodic orbits. This yields useful insights into network behavior, but the cost is that one needs to study nonsmooth dynamical systems. The study of nonsmooth systems is well developed when focusing on the interacting units (i.e., at the node level) of a system, and we give a detailed presentation of how to use saltation operators, which can treat the propagation of perturbations through switching manifolds, to understand dynamics and bifurcations at the network level. We illustrate this merger of tools and techniques from network science and nonsmooth dynamical systems with applications to neural systems, cardiac systems, networks of electromechanical oscillators, and cooperation in cattle herds.

What Happens in Seoul Stays in Seoul (2024 Edition)
I am off to Seoul to speak in a workshop on Theoretical Challenges in Network Science! I really enjoy visiting Seoul, and I am very happy to have another chance to visit.
