Evolving patterns in the Terrorist Threat Landscape: Online Radicalisation in the age of Artificial Intelligence

Lara Raggi, Matteo Muratori, Alessandro Zanasi, Ustenko Maria

The terrorist threat landscape has changed significantly in recent years, challenging conventional definitions of terrorism. A growing number of attacks now sit in a ‘grey zone’ between terrorist-type violence, personal grievance, psychological vulnerability, social alienation and fragmented ideology. This does not mean …

SERA (Scenario Evaluation and Regionalization Analysis Model) [SWR-17-57]

Justin Bracci, Mark Chung, Brian Bush, Ambarish Nag et autres

The Scenario Evaluation and Regionalization Analysis (SERA) model provides insights that can guide infrastructure development and investment decisions for hydrogen and other commodities at scale. The SERA model can evaluate both the supply and demand sides of a commodity market. The SERA …

A porous medium equation with rough weights: Sharp Widder theory

Gabriele Grillo, Matteo Muratori, Troy Petitt, Nikita Simonov

We establish an optimal \emph{Widder theory} for a weighted porous medium equation with rough and inhomogeneous density that may be singular at a point and tends to zero at spatial infinity. Specifically, for this equation, we identify a class $X$ of initial …

Cradle-to-Grave Lifecycle Analysis of U.S. Medium- and Heavy-Duty Vehicle-Fuel Pathways: A Greenhouse Gas Emissions Assessment of Current (2021) and Future (2035) Technologies

Jarod C. Kelly, Amgad Elgowainy, Ram Vijayagopal, Matteo Muratori et autres

This study presents a cradle-to-grave lifecycle analysis of energy use and greenhouse gas (GHG) emissions for U.S. medium- and heavy-duty vehicles across current (2021) and future (2035) technologies using the Greenhouse gas, Regulated Emissions, and Energy use in Technologies (GREET) model with …

On the subcritical Lane-Emden equation on Riemannian models with polynomial volume growth

Alessandra De Luca, Matteo Muratori, Nicola Soave

We focus on the problems of existence and non-existence of positive solutions for the Sobolev-subcritical Lane-Emden equation on certain Riemannian manifolds (mainly models) with asymptotically negative curvature, which, from the viewpoint of the volume growth of geodesic balls, can be regarded as …

A general nonlinear characterization of stochastic incompleteness

Gabriele Grillo, Kazuhiro Ishige, Matteo Muratori, Fabio Punzo

Stochastic incompleteness of a Riemannian manifold M amounts to the nonconservation of probability for the heat semigroup on M . We show that this property is equivalent to the existence of nonnegative, nontrivial, bounded (sub)solutions to Δ W = ψ ( W …

ToonOut: Fine-tuned Background-Removal for Anime Characters

Matteo Muratori, Joël Seytre

While state-of-the-art background removal models excel at realistic imagery, they frequently underperform in specialized domains such as anime-style content, where complex features like hair and transparency present unique challenges. To address this limitation, we collected and annotated a custom dataset of 1,228 …

Transportation in net-zero emissions futures: Insights from the EMF-37 model intercomparison study

Christopher G. Hoehne, Matteo Muratori, John E T Bistline, Carol Shay Lenox et autres

emissions by 2050. We find the U.S. transport sector is poised to play the most significant role in reducing demand-side emissions, mostly driven by technology substitution, as modeling results suggest a limited role for mode shifting and for reduced use of personal …
