Input-Power-to-State Stability of Time-Varying Systems
When the state of a system may remain bounded even if both the input amplitude and energy are unbounded, then the state bounds given by the standard input-to-state stability (ISS) and integral-ISS (iISS) properties may provide no useful information. This paper considers an ISS-related concept suitable in such a case: input-power-to-state stability (IPSS). Necessary and sufficient conditions for IPSS are developed for time-varying systems under very mild assumptions on the dynamics. More precise…

Information-theoretic machine learning for time-varying mode decomposition of separated airfoil wakes
We perform an information-theoretic mode decomposition for separated wakes around a wing. The current data-driven approach based on a neural network referred to as deep sigmoidal flow enables the extraction of an informative component from a given flow field snapshot with respect to a target variable at a future time stamp, thereby capturing the causality as a time-varying modal structure. We consider three examples of separated flows around a NACA0012 airfoil, namely, 1. laminar periodic wake …

Wat zou er gebeuren als de stemwijzers je zouden vragen naar je inkomen en vermogen en dat mee zouden nemen? Of projectie zouden geven bij de top drie die je kiest?
Anders gezegd, geven stemwijzers volgens jullie een eerlijk stemadvies?

Efficient Sampling for Realized Variance Estimation in Time-Changed Diffusion Models
This paper analyzes the benefits of sampling intraday returns in intrinsic time for the realized variance (RV) estimator. We theoretically show in finite samples that depending on the permitted sampling information, the RV estimator is most efficient under either hitting time sampling that samples whenever the price changes by a pre-determined threshold, or under the new concept of realized business time that samples according to a combination of observed trades and estimated tick variance. The…

$L_2$-norm posterior contraction in Gaussian models with unknown variance
The testing-based approach is a fundamental tool for establishing posterior contraction rates. Although the Hellinger metric is attractive owing to the existence of a desirable test function, it is not directly applicable in Gaussian models, because translating the Hellinger metric into more intuitive metrics typically requires strong boundedness conditions. When the variance is known, this issue can be addressed by directly constructing a test function relative to the $L_2$-metric using the li…

US-Analysten: Smartphone-Verkäufe wegen US-Zollpolitik unter Druck 
Die Markforscher von IDC haben ihre Verkaufs-Prognose für Smartphones nach unten korrigiert. Ein Grund ist die wachsende Verunsicherung der US-Verbraucher.
