Selenskyj bestätigt Gefangenenaustausch
Der ukrainische Präsident Wolodymyr Selenskyj hat den Austausch von Kriegsgefangenen in seinem Telegram-Kanal bestätigt. Die meisten nun heimgekehrten Ukrainer seien bereits seit 2022 in Gefangenschaft gewesen, schrieb Selenskyj. Demnach handelte es sich um Soldaten, Angehörige der Nationalgarde, des Grenzschutzes und der Eisenbahntruppen, aber auch um Zivilis…

Truthful, Credible, and Optimal Auctions for Matroids via Blockchains and Commitments
We consider a revenue-optimizing auctioneer in single-dimensional environments with matroid feasibility constraints. Akbarpour and Li (2020) argue that any revenue-optimal, truthful, and credible mechanism requires unbounded communication. Recent works (Ferreira and Weinberg, 2020; Essaidi et al., 2022; Chitra et al., 2024) circumvent their impossibility for the single-item setting through the use of cryptographic commitments and blockchains. We extend their results to matroid feasibility const…

Ich habe schon einige Male von meiner privaten Zeiterfassung mit #toggl berichtet, die ich im Sommer 2022 gestartet habe:

A natural and short proof of Lee's conjecture on the Frobenius norm
In 2010, Eun-Young Lee conjectured that if $A,B$ are two $n\times n$ complex matrices and $\left|A\right|, \left|B\right|$ are the absolute values of $A, B$, respectively, then \[ \|A+B\|_F\le \sqrt{\dfrac{1+\sqrt{2}}{2}}\|\left|A\right|+\left|B\right|\|_F, \] where $\|\cdot\|_F$ is the Frobenius norm of matrices. This conjecture was initially proven by Lin and Zhang [J. Math. Anal. Appl. 516 (2022) 126542] by studying inequa…

Coherent electrically-charged quantum black holes
We improve upon the results presented in [R. Casadio, et al., Phys. Rev. D 105 (2022) 124026] deriving a quantum-corrected Reissner-Nordström geometry containing an integrable singularity at its center while being devoid of spurious oscillations around the classical configuration. We further investigate some relevant physical observables, related to geodesics and quasinormal modes of scalar perturbations, associated with this geometry to complement our theoretical analysis.

$\mathcal{B}(B\rightarrowτν)$ measurement with the hadronic FEI at Belle~II
We presented at Moriond EW 2025 a measurement of the branching fraction of $B\toτν$ decays using $(387\pm 6) \times 10^6$ $Υ(4S)$ collected between 2019 and 2022 with the Belle~II detector at the SuperKEKB $e^+e^-$ collider. We reconstruct the accompanying $B^-$ meson using the hadronic tagging method, while $B\toτν$ candidates are identified in the recoil. We find evidence for $B\toτν$ decays at 3.0 standard deviations, including systematic uncertainties. The measured branching fraction…

Central Bank Communication with Public: Bank of England and Twitter (X)
Central banks increasingly use social media to communicate beyond financial markets, yet evidence on public engagement effectiveness remains limited. Despite 113 central banks joining Twitter between 2008 and 2018, we lack understanding of what drives audience interaction with their content. To examine engagement determinants, we analyzed 3.13 million tweets mentioning the Bank of England from 2007 to 2022, including 9,810 official posts. We investigate posting patterns, measure engagement elas…

A Data-Driven Model Predictive Controller to manage epidemics: The case of SARS-CoV-2 in Mauritius
This work investigates the benefits of implementing a systematic approach to social isolation policies during epidemics. We develop a mixed integer data-driven model predictive control (MPC) scheme based on an SIHRD model which is identified from available data. The case of the spread of the SARS-CoV-2 virus (also known as COVID-19) in Mauritius is used as a reference point with data obtained during the period December 2021 to May 2022. The isolation scheme is designed with the control decision…

Unveiling Political Influence Through Social Media: Network and Causal Dynamics in the 2022 French Presidential Election
During the 2022 French presidential election, we collected daily Twitter messages on key topics posted by political candidates and their close networks. Using a data-driven approach, we analyze interactions among political parties, identifying central topics that shape the landscape of political debate. Moving beyond traditional correlation analyses, we apply a causal inference technique: Convergent Cross Mapping, to uncover directional influences among political communities, revealing how some…

Evaluation empirique de la sécurisation et de l'alignement de ChatGPT et Gemini: analyse comparative des vulnérabilités par expérimentations de jailbreaks
Large Language models (LLMs) are transforming digital usage, particularly in text generation, image creation, information retrieval and code development. ChatGPT, launched by OpenAI in November 2022, quickly became a reference, prompting the emergence of competitors such as Google's Gemini. However, these technological advances raise new cybersecurity challenges, including prompt injection attacks, the circumvention of regulatory measures (jailbreaking), the spread of misinformation (hallucinat…

Effect of Different Concentration and Application Method of Zinc on Yield of Chickpea (Pisum Sativum L.)
This study evaluated the impact of Zinc (Zn) supplementation on the growth, yield, and seed quality of chickpea (Pisum sativum L.) under the semi-arid conditions of Kerman, Iran, across two growing seasons (2021-2022). A randomized complete block design was used with six treatments, including varying concentrations of zinc sulphate applied via foliar spraying (0.1%, 0.25%, 0.5%) or irrigation (4, 8, 16 kg/ha), each applied twice-one and two months after greening. Results from the first year rev…

"Stop Killing Games" hat heute die 1 Million Unterschriften überschritten.
Es ist damit nach der Konversionstherapien-Stopp- (Mai), und der Sichere-Abtreibungs- (April) die dritte Europäische Bürgerinitiative dieses Jahr, die die Unterschriftenhürde schafft.
In den letzten Jahren haben das nur die Anti-Pelz- (2023) und Anti-Tierversuch- (2022) -Initiativen geschafft.
Interessante Entwicklung.
