Ein Hinweis zur Stabilität des Dunklen Energiemodells von Zeitkristallen
In dieser Notiz, we investigate the stability of the dark energy model from time crystals proposed in [1]. Wir legen Wert auf zwei Zutaten, the coupling of the scalar field to gravity, and the fact that these time crystals are on an expanding FRW...
Reduktion $ε$-erweiterter Feynman-Integrale
Since Feynman integrals (FIs) at higher spacetime dimensions are free of infrared and collinear divergence–and their ultraviolet divergences can be systematically subtracted–this allows us to construct a wide range of locally finite Feynman integrals. Especially, we propose a method named $\bar{R}$-operation to...
Online-Modelllernen mit datenassimilierten Reservoircomputern
We propose an online learning framework for forecasting nonlinear spatio-temporal signals (Felder). Die Methode integriert (ich) Dimensionsreduktion, Hier, eine einfache richtige orthogonale Zerlegung (POD) Vorsprung; (ii) ein verallgemeinertes autoregressives Modell zur Vorhersage reduzierter Dynamik, Hier, a reservoir computer; (iii) online adaptation...
Tiefenphotonischer Reservoircomputer für nichtlinearen Ausgleich von 16 Ebenen Quadraturamplitudenmodulationssignale
Photonischer Reservoircomputer (VR China) is a kind of real-time and adaptive recurrent neural network, where only weights in the readout layer require training. PRC is a promising tool to deal with the crucial issue of nonlinear equalization in optical fiber communications. Here...
Projektive Sortenwiederherstellung aus unbekannten linearen Projektionen
We study how a smooth irreducible algebraic variety $X$ of dimension $n$ embedded in $\mathbb{C} \mathbb{P}^{M}$ (with $m \geq n+2$), which degree is $d$, can be recovered using two projections from unknown points onto unknown hyperplanes. The centers and the hyperplanes of...
Systemische Schuppenbildung: Eine empirische Analyse des gleichzeitig auftretenden Flockentests Misserfolge
Flaky-Tests führen ohne Codeänderungen zu inkonsistenten Ergebnissen, creating major challenges for software developers. An industrial case study reported that developers spend 1.28% of their time repairing flaky tests at a monthly cost of $2,250. We discovered that flaky tests often exist...
Evaluation Framework for AI Systems in “the Wild”
Generative AI (GenAI) models have become vital across industries, yet current evaluation methods have not adapted to their widespread use. Traditional evaluations often rely on benchmarks and fixed datasets, frequently failing to reflect real-world performance, which creates a gap between lab-tested outcomes...
Lineare Regression unter Verwendung von Hilbert-Raum-wertigen Kovariaten mit Unbekanntem Kernel reproduzieren
We present a new method of linear regression based on principal components using Hilbert-space-valued covariates with unknown reproducing kernels. We develop a computationally efficient approach to estimation and derive asymptotic theory for the regression parameter estimates under mild assumptions. We demonstrate the...
Dehnungseffekt auf Rashba-Spaltung und Phononenstreuung zur Verbesserung Thermoelektrische Leistung von 2D-Heterobischicht-MoTe$_{2}$/PtS$_{2}$
Rashba spin-orbit coupling significantly modifies the electronic band structure in two-dimensional (2D) van der Waals (vdW) Heterobischichten, which may enhance their thermoelectric (DER) Eigenschaften. In dieser Studie, we use first-principles calculations and Boltzmann transport theory to explore the strain effect on the...
Graph2Nav: 3D Generierung von Objektbeziehungsdiagrammen für die Roboternavigation
We propose Graph2Nav, a real-time 3D object-relation graph generation framework, for autonomous navigation in the real world. Our framework fully generates and exploits both 3D objects and a rich set of semantic relationships among objects in a 3D layered scene graph, which...
