Inflation Model Based on Virasoro Squeezing
We propose a novel mechanism for realizing slow-roll inflation that is fully consistent with observational data, based on conformal transformations acting exclusively on a complex scalar field -- without coupling to the gravitational sector. These transformations generically produce a plateau in the inflaton potential, as guaranteed by the maximum modulus theorem, thereby naturally satisfying the slow-roll conditions. Our framework utilizes squeezing operations generated by the Virasoro algeb…

Langmuir Wave Excitation in Solar-wind Magnetic Holes
Magnetic holes are structures commonly observed in various space plasma environments throughout the solar system, including the solar wind. These structures are characterized by a localized decrease in magnetic field strength, coincident with an increase in plasma density. Previous observational studies in the solar wind link the presence of Langmuir waves to magnetic holes, suggesting a strong correlation between these phenomena. We develop a model based on magnetic-moment conservation and its…

Virasoro constraints for Hodge integrals
The purpose of this paper is to study Virasoro constraints for Hodge integrals in Gromov-Witten theory of any target varieties. Results consist of the following: Firstly, we propose Virasoro conjecture for Hodge integrals in Gromov-Witten theory of any target varieties; Secondly, we prove Virasoro constraints for Hodge integrals in genus zero of any target varieties; Thirdly, we prove the genus-1 $L_1^{\mathbb{E}}$ constraint with one Hodge character class insertion for any target varieties; La…

A Data-Driven Approach for Topology Correction in Low Voltage Networks with DERs
This paper introduces a data-driven topology identification and correction approach for low-voltage distribution networks (LVDNs) combined with a time-based smart meter data selection strategy, aiming to correct outdated recordings and identify the missed recordings. The proposed approach solely relies on voltage magnitude measurements, releasing privacy concerns and measurement burdens. It enables the distribution system operators to identify switch states through supervised learning algorithm…

Wero: Luxemburg stößt hinzu
„Ab Juni 2026 können Kunden von Spuerkeess, BIL, POST Luxembourg, Raiffeisen und BGL BNP Paribas die digitale Wallet Wero nutzen.“
„Zu erwähnen ist auch die geplante Integration von Payconiq, das 2023 von EPI übernommen wurde. Die Umstellung soll schrittweise erfolgen, wobei Payconiq voraussichtlich bis September 2026 vollständig durch Wero ersetzt wird.“
