A Stochastic Lattice Model for Convective Self-aggregation Incorporating Longwave Radiative Effect
Self-aggregation of tropical convection is a universal feature observed in a diverse range of atmospheric environments. Several preceding models conceptualized the self-aggregation of convection as a phase transition driven by collisions between cold pool gust fronts. Jedoch, self-aggregation may also be influenced...
Microstructure and Manipulation: Quantifying Pump-and-Dump Dynamics in Cryptocurrency Markets
Building on our prior threshold-based analysis of six months of Poloniex trading data, we have extended both the temporal span and granularity of our study by incorporating minute-level OHLCV records for 1021 tokens around each confirmed pump-and-dump event. Erste, we algorithmically identify...
Spontane Stochastizität und der passive Skalar von Armstrong-Vicol
Spontaneous stochasticity refers to the emergence of intrinsic randomness in deterministic systems under singular limits, a phenomenon conjectured to be fundamental in turbulence. Armstrong and Vicol \citep{AV23,AV24} recently constructed a deterministic, divergence-free multiscale vector field arbitrarily close to a weak Euler solution,...
Endlicher Zeit-Max-Konsens für gleichzeitiges Abfangen von Zielen in Umschalten von Graphentopologien
In diesem Papier, we propose a distributed guidance law for the simultaneous interception of a stationary target. Für eine Gruppe von `n’ heterogene Verfolger, the proposed guidance law establishes the necessary conditions on static graphs that ensure simultaneous target interception, regardless of...
No-Regret-Modell-Vorhersagesteuerung mit Online-Lernen von Koopman Betreiber
We study a problem of simultaneous system identification and model predictive control of nonlinear systems. Particularly, we provide an algorithm for systems with unknown residual dynamics that can be expressed by Koopman operators. Such residual dynamics can model external disturbances and modeling...
Quantengeschwindigkeitsgrenzen in der Qubit-Dynamik, angetrieben durch bistabilen Zufall Telegraphenlärm: Von markovianischen zu nicht-markovianischen Regimen
Wir untersuchen das Quantengeschwindigkeitslimit (QSL) of a single superconducting qubit subjected to pure dephasing induced by bistable random telegraph noise (RTN), eine häufige Umweltstörung in Festkörperquantensystemen. Using an exactly solvable model, we explore how the interplay...
Schnelle Interpolation und Einschränkung höherer Ordnung bei der ExaHyPE-Vermeidung Nicht-physische Reflexionen
Wave equations help us to understand phenomena ranging from earthquakes to tsunamis. Diese Phänomene treten in sehr großen Maßstäben auf. It would be computationally infeasible to track them over a regular mesh. Noch, since the phenomena are localised, adaptive Netzverfeinerung (AMR) can...
WIRKUNG: Eine hocheffiziente Full-Stack-FHE-Beschleunigungsplattform
Vollständig homomorphe Verschlüsselung (FHE) is a set of powerful cryptographic schemes that allows computation to be performed directly on encrypted data with an unlimited depth. Trotz der vielversprechenden Leistungen von FHE im Bereich datenschutzschonender Datenverarbeitung, yet in most FHE schemes, ciphertext generally blows up thousands of...
Verzögertes Keen-Modell mit Inflation
Keens Modell beschreibt die Dynamik zwischen Lohnanteilen, employment rate and debt ratio. In der Literatur, the model was extended to represent the effects of inflation and also the speculative money flow. Basierend auf dem Inflationsmodell, we take into account a time...
Charakterisierung und Ex-vivo-Anwendung flexibler 2D-Szintillation Beschichtungen in Elektronenstrahlen mit ultrahoher Dosisleistung für die FLASH-Strahlentherapie
The increasing interest in FLASH-RT has lead to the conversion of linear accelerators to enable ultra-high dose rate (UHDR) beams for preclinical research. Dosimetry hereof remains challenging with several crucial aspects missing. Diese Arbeit zeigt die Herausforderungen für die Echtzeit-2D-UHDR-Dosimetrie,...
