Cedalion Tutorial: A Python-based framework for comprehensive analysis of multimodal fNIRS & DOT from the lab to the everyday world

E. Middell, L. Carlton, S. Moradi +10

Functional near-infrared spectroscopy (fNIRS) and diffuse optical tomography (DOT) are rapidly evolving toward wearable, multimodal, and data-driven, AI-supported neuroimaging in t…

On black hole singularity resolution in via duality-invariant corrections

Tomas Codina, Olaf Hohm, Barton Zwiebach

Starting with the two-derivative limit of string theory, we explore the space of T-duality invariant corrections, a space that contains a point representing the fully $α…

2D Black Holes, Bianchi I Cosmologies, and

Tomas Codina, Olaf Hohm, Barton Zwiebach

We report two surprising results on corrections in string theory restricted to massless fields. First, for critical dimension Bianchi type I cosmologies with scale factors…

An -complete theory of cosmology and its tensionless limit

Tomas Codina, Olaf Hohm, Diego Marques

We explore the exactly duality invariant higher-derivative extension of double field theory due to Hohm, Siegel and Zwiebach (HSZ) specialized to cosmological backgrounds. Despite…

Duality invariant string beta functions at two loops

Roberto Bonezzi, Tomas Codina, Olaf Hohm

We compute, for cosmological backgrounds, the invariant beta functions for the sigma model of the bosonic string at two loops. This yields an independent first-…

General String Cosmologies at Order

Tomas Codina, Olaf Hohm, Diego Marques

We compute the cosmological reduction of general string theories, including bosonic, heterotic and type II string theory to order , i.e., with up to eight derivatives. To t…
