En Suisse, un quart du trafic est généré par le tourisme
👉 Le tourisme: 25% du trafic global
👉 24% de ces déplacements en transports publics (TP)
👉 Fortes fluctuations (pics saisonniers/hebdomadaires)
👉 Défi important: part modale des TP pour le trafic de transit & transfrontalier
👉 Mieux exploiter le potentiel offert par l’offre TP couvrant l’ensemble du territoire national afin de mieux répartir la demande tout en tirant partie des capacités existantes

Characterizing infinite torsion subgroups of the circle through arithmetic-type sequences
In a recent work [Das et al., Bull. Sci. Math. 199 (2025), 103580], the structure of characterized subgroups corresponding to arithmetic-type sequences was investigated. Building upon this work, we further show that a characterized subgroup associated with an arithmetic-type sequence is countable if and only if it is torsion. Further we prove that any infinite torsion subgroup of the circle can be characterized by an arithmetic-type sequence with bounded ratio. Moreover, our findings demonstrat…

Oh nur noch noch drei Wochen bis Polarkreis/ Kungsleden.
Eventuell sollte ich mich nach meinem behobenen Leistenbruch mal etwas mehr bewegen 😬

On balanced Hermitian threefolds with parallel Bismut torsion
We continue our study on Hermitian manifolds that are {\em Bismut torsion parallel,} or {\em BTP} for brevity, which means that the Bismut connection has parallel torsion tensor. For $n\geq 3$, BTP metrics can be balanced (and non-Kähler). In this paper, we give a classification of all compact, balanced BTP threefolds.

Detecting Hardware Trojans in Microprocessors via Hardware Error Correction Code-based Modules
Software-exploitable Hardware Trojans (HTs) enable attackers to execute unauthorized software or gain illicit access to privileged operations. This manuscript introduces a hardware-based methodology for detecting runtime HT activations using Error Correction Codes (ECCs) on a RISC-V microprocessor. Specifically, it focuses on HTs that inject malicious instructions, disrupting the normal execution flow by triggering unauthorized programs. To counter this threat, the manuscript introduces a Hardw…

For the first time, a team at Western University in collaboration with the Defence Research and Development Canada has used a satellite-tracking camera system to monitor #satellites over the high Arctic: https://spaceq.ca/meteor-tracking-camera-tech-used-to-track-satellites-in-the-high-arctic/

Die Bahn ist so ein Saftladen. (Aktuelle Verspätung noch vor Abfahrt: 35 Min.)
Mir erzählte neulich eine Person, die da arbeitet, dass jetzt prioritär Trassen saniert werden, die im Kriegsfall für Truppentransporte benutzt werden.
Dazu würde ich auch gern mal eine Recherche sehen.

Isolated singularities in $G_2$-structures with torsion
We revisit the study of $G_2$-structures with special torsion, and isolated singularities. Many of the known examples with conical singularities admit additional symmetries, and we describe circle-invariant $G_2$-structures in this context. Finally, we show that collapsing the circle fibres of a contact Calabi-Yau manifold at isolated points cannot produce a $G_2$-structure with bounded torsion.
