SuomiAreenan keskustelu: Turvallisuus ympäristö- ja ilmastohaasteiden keskellä 26.6.2025
Luontokato ja ympäristön saastuminen vaikuttavat jo nyt ihmisten arkeen ja terveyteen. Kasvavat ilmastoriskit uhkaavat energiaturvallisuutta, infrastruktuuria, vesivaroja ja taloudellista vakautta. Miten voimme kääntää haasteet mahdollisuuksiksi ja vahvistaa yhteiskuntamme turvallisuutta ja kilpailukykyä?

The Trump administration is thinking about adding 26 more countries
—most of them African
—to his travel ban list.
The Washington Post obtained a Trump administration memo that would give the 26 countries listed 60 days to capitulate to State Department demands.
Some countries were flagged for having “no competent or cooperative central government authority to produce reliable identity documents or other civil documents,”
or “government fraud.”
There was …

Trump Wants to Ban a Quarter of the World From Traveling to the U.S.
If put into effect, it could jeopardize future events like the 2026 World Cup and 2028 Olympics.

On generalised Pythagorean triples over number fields
Generalised Pythagorean triples are integer tuples $(x,y,z)$ satisfying the equation $E_{a,b,c}: ax^2+by^2+cz^2=0$. A significant amount of research has been devoted towards understanding generalised Pythagorean triples and, in particular, we can now determine whether $E_{a,b,c}$ has solutions and find them in a computationally effective manner. In this paper, we consider an extension of generalised Pythagorean triples to number fields $K$. In particular, we survey and extend the existing res…

Efficient Multi-Camera Tokenization with Triplanes for End-to-End Driving
Autoregressive Transformers are increasingly being deployed as end-to-end robot and autonomous vehicle (AV) policy architectures, owing to their scalability and potential to leverage internet-scale pretraining for generalization. Accordingly, tokenizing sensor data efficiently is paramount to ensuring the real-time feasibility of such architectures on embedded hardware. To this end, we present an efficient triplane-based multi-camera tokenization strategy that leverages recent advances in 3D ne…

A triple torsion linking form and 3-manifolds in $S^4$
Given a rational homology 3-sphere $M$, we introduce a triple linking form on $H_1(M; \mathbb{Z})$, defined when the classical torsion linking pairing of three homology classes vanishes pairwise. If $M$ is the boundary of a simply-connected 4-manifold $N$, the triple linking form can be computed in terms of the higher order intersection form on $N$, introduced by Matsumoto. We use these methods to formulate an embedding obstruction for rational homology spheres in $S^4$, extending a 1938 theore…

France’s Macron Faces Dilemma With Intention to Recognize Palestinian State
The French-Israeli relationship has always been turbulent, but the prospect that President Emmanuel Macron may recognize a Palestinian state has brought tension to a new level.

Demographics-Informed Neural Network for Multi-Modal Spatiotemporal forecasting of Urban Growth and Travel Patterns Using Satellite Imagery
This study presents a novel demographics informed deep learning framework designed to forecast urban spatial transformations by jointly modeling geographic satellite imagery, socio-demographics, and travel behavior dynamics. The proposed model employs an encoder-decoder architecture with temporal gated residual connections, integrating satellite imagery and demographic data to accurately forecast future spatial transformations. The study also introduces a demographics prediction component which…
