Global Regularity For The Nonlinear Wave Equation With Slightly Supercritical Power

Maria Colombo, Silja Noëmi Aline Haffter

We consider the defocusing nonlinear wave equation ❑u D jujp ⠀1u in R3 ⠂ & UOELIG;0; 1/. We prove that for any initial datum with a scaling-subcritical norm bounded by M0 the equation is globally well-posed for p D 5 C i, where i 2 .0; ...

Phase diagram of Stochastic Gradient Descent in high-dimensional two-layer neural networks

Florent Gérard Krzakala, Lenka Zdeborová, Ludovic Théo Stephan, Bruno Loureiro

Despite the non-convex optimization landscape, over-parametrized shallow networks are able to achieve global convergence under gradient descent. The picture can be radically different for narrow net-works, which tend to get stuck in badly-generalizing loca ...

What about the ethics of applying artificial intelligence to bodies?

Images convey, through representations of bodies, in the press, cinema and art, one or more gender imaginaries while acting as vectors in the process of globalization. The recurrence or similarity of some of these images reveals the diffusion or persistenc ...

Ephemeral Astroturfing Attacks: The Case of Fake Twitter Trends

Karl Aberer, Tugrulcan Elmas, Rebekah Jean Overdorf, Ahmed Furkan Ozkalay

We uncover a previously unknown, ongoing astroturfing attack on the popularity mechanisms of social media platforms: ephemeral astroturfing attacks. In this attack, a chosen keyword or topic is artificially promoted by coordinated and inauthentic activity ...

Liminality, Ephemerality, and Marginality with Impact Makerspaces in the Chinese Urban Fabric: Shanghai, Shenzhen, Beijing, and Addis Ababa

Monique Stéphanie Bolli

In the last few years, narratives and imaginaries about maker cultures as well as makerspaces have been flourishing in Chinese cities. With its fast-changing pace, the global maker movement expresses unique features in China and integrates aspects of grass ...

Les grands projets urbains entre global et local : une étude de cas comparative de Casablanca et de Genève à travers les logiques de marché et les résistances locales.

Kamil Hajji

Globalization implies profound changes in territories that involve the emergence of major urban renewal projects. It has the effect of increasing competition between metropolises. In order to make a place for themselves in this increasingly competitive glo ...

Signatures of coherent flow structures in the atmospheric surface layer over Lake Geneva

David Andrew Barry, Ulrich Lemmin, Mehrshad Foroughan

Reliable estimates of air-water exchange of momentum, heat, and gas are vital for understanding boundary layer dynamics and for developing accurate global and regional climate and weather forecasting models. Spatiotemporal variability of physical processes ...

Small data global regularity for half-wave maps in n=4 dimensions

Joachim Krieger, Anna Kiesenhofer

We prove that the half-wave maps problem on

S^2

is globally well-posed for smooth initial data which are small in the critical

Makers in China: a model to export?

Monique Stéphanie Bolli

The creation of social innovation labs, living labs, hackerspaces, makerspaces, fablabs and innovation parks indicates local, national, and international dynamics. China is unique in the rapid transformation of the maker movement, where the bottom-up initi ...

The Architecture of the Metacity: Land Use Change, Patch Dynamics and Urban Form in Chiang Mai, Thailand

Martina Barcelloni Corte

This essay analyzes the spatial and temporal dynamics which have emerged from the rapid development of Chiang Mai, Thailand over the last four decades. Modern urbanization since the 1980s in the previously remote Chiang Mai-Lamphun Valley has coincided wit ...
