We've Issued Our First IP Address Certificate
Since Let’s Encrypt started issuing certificates in 2015, people have repeatedly requested the ability to get certificates for IP addresses, an option that only a few certificate authorities have offered. Until now, they’ve had to look elsewhere, because we haven’t provided that feature. Today, we’ve issued our first certificate for an IP address, as we announced we would in January. As with other new certificate features on our engineering roadmap, we’ll now start gradually rolling o…

PSAT: Pediatric Segmentation Approaches via Adult Augmentations and Transfer Learning
Pediatric medical imaging presents unique challenges due to significant anatomical and developmental differences compared to adults. Direct application of segmentation models trained on adult data often yields suboptimal performance, particularly for small or rapidly evolving structures. To address these challenges, several strategies leveraging the nnU-Net framework have been proposed, differing along four key axes: (i) the fingerprint dataset (adult, pediatric, or a combination thereof) from …

New universality classes govern the critical and multicritical behavior of an active Ising model

New universality classes govern the critical and multicritical behavior of an active Ising model
The Ising model is one of the most well known models in statistical physics, with its critical behavior governed by the Wilson-Fisher universality class (UC). When active motility is incorporated into the Ising model by, e.g., dictating that the spins' directional movements follow their orientations, the spin number density necessarily constitutes a soft mode in the hydrodynamic description, and can therefore modify the scaling behavior of the system. Here, we show that this is indeed the case …

Ibsen in Norway: Peer Gynt at Gålå - iconic performance in spectacular nature - Ibsenbyen Skien
Over the years, Peer Gynt at Gålåvannet has been a great theater experience for many people. The summer of 2024 will be no exception - between August 1 and 10, Peer Gynt will be performed nine times.

A Neuronal Model at the Edge of Criticality: An Ising-Inspired Approach to Brain Dynamics

A Neuronal Model at the Edge of Criticality: An Ising-Inspired Approach to Brain Dynamics
We present a neuronal network model inspired by the Ising model, where each neuron is a binary spin ($s_i = \pm1$) interacting with its neighbors on a 2D lattice. Updates are asynchronous and follow Metropolis dynamics, with a temperature-like parameter $T$ introducing stochasticity. To incorporate physiological realism, each neuron includes fixed on/off durations, mimicking the refractory period found in real neurons. These counters prevent immediate reactivation, adding biologically grounde…

Chladni states in Ising Spin Lattices
Spontaneous symmetry breaking is the core concept for understanding the emergence of collective order. In finite-dimensional systems, however, the nature of the broken phase is often constrained by the compatibility between spontaneous order and the microscopic symmetries of the underlying lattice. Here, we propose the topological substratum on which Ising spin lattices exhibit long-range order when cooled under non-ergodic conditions. Our topological decomposition, tantamount to resonating san…
