Modelling Coincident Particle Production in Ultraperipheral Heavy Ion Collisions
In this paper, we present an analysis of coincident particle production in ultraperipheral heavy ion collisions. In particular, we present the first detailed and differential predictions for coincident $ρ^0$ meson production in association with muon pair production, motivated by the recent ATLAS measurement of this process. These are found to describe the data well, including the dependence of the coincidence fraction on the ZDC selection and/or other kinematic constraints on the muons. Differ…

MULTISS: un protocole de stockage confidentiel {à} long terme sur plusieurs r{é}seaux QKD
This paper presents MULTISS, a new protocol for long-term storage distributed across multiple Quantum Key Distribution (QKD) networks. This protocol is an extension of LINCOS, a secure storage protocol that uses Shamir secret sharing for secret storage on a single QKD network. Our protocol uses hierarchical secret sharing to distribute a secret across multiple QKD networks while ensuring perfect security. Our protocol further allows for sharing updates without having to reconstruct the entire s…

Maximizing the Value of Predictions in Control: Accuracy Is Not Enough
We study the value of stochastic predictions in online optimal control with random disturbances. Prior work provides performance guarantees based on prediction error but ignores the stochastic dependence between predictions and disturbances. We introduce a general framework modeling their joint distribution and define "prediction power" as the control cost improvement from the optimal use of predictions compared to ignoring the predictions. In the time-varying Linear Quadratic Regulator (LQR) s…

product_space: Atlas of Economic Complexity export network
Two networks of economic products, where a pair of products are connected if they are exported at similar rates by the same countries. The data are a projection from a bipartite network of nations and the products they export. Edges weights represent a similarity score (called "proximity"). Data based on UN Comtrade worldwide trade patterns. SITC network based on the Standard International Trade Classification and HS …

Trump ordered his White House counsel and the attorney general on Wednesday to investigate former President Joseph R. Biden Jr. and his staff -- in Mr. Trump’s latest attempt to stoke outlandish conspiracy theories about his predecessor.
In an executive order, Mr. Trump put the power and resources of the federal government to work examining whether some of Mr. Biden’s presidential actions were legally invalid because his aides had enacted those policies without his knowledge.
The e…

Towards Trustworthy Federated Learning with Untrusted Participants
Resilience against malicious participants and data privacy are essential for trustworthy federated learning, yet achieving both with good utility typically requires the strong assumption of a trusted central server. This paper shows that a significantly weaker assumption suffices: each pair of participants shares a randomness seed unknown to others. In a setting where malicious participants may collude with an untrusted server, we propose CafCor, an algorithm that integrates robust gradient agg…

Kreml zu Telefonaten mit Trump und Papst
Das Telefonat zwischen US-Präsident Donald Trump und Russlands Präsident Wladimir Putin wertete Juri Uschakow, Berater des russischen Staatschefs, als "produktiv". Es sei in dem Gespräch auch um die ukrainischen Drohnenangriffe auf russische Militärstützpunkte am Wochenende gegangen. Trump habe betont, dass die USA nicht im Vorfeld informiert worden seien. Sowohl Trump als auch Putin h…
