POINTWISE UNIVERSAL CONSISTENCY OF NONPARAMETRIC LINEAR ESTIMATORS [PDF]
This paper presents sufficient conditions for pointwise universal consistency of nonparametric delta estimators. We show the applicability of these conditions for some classes of nonparametric estimators.

High‐Order Projection‐Based Upwind Method for Simulation of Transitional Turbulent Flows
International Journal for Numerical Methods in Fluids, EarlyView.In this study, we evaluated the implicit large‐eddy simulation capabilities of the mass‐conserving mixed stress method for transitional turbulent flows and proposed an efficient solution method for large‐scale applications. The results presented in this work show promising outcomes for incompressible aerodynamic flow problems, which can be further ...

Journal of Forecasting, EarlyView.ABSTRACT Deep learning‐based long time series forecasting (LTSF) has achieved high accuracy by effectively capturing the underlying trends, seasonality, and temporal dependencies within time series data. However, at the individual entity level, termed the low aggregation level (LAL), intermittency, irregularity, and data sparsity undermine the ...

Journal of Forecasting, EarlyView.ABSTRACT This paper develops Masked Asset–Regime Scenario Diffusion (MARS‐Diff), a leakage‐disciplined framework for probabilistic forecasting of multiday portfolio losses. The framework combines a regularized heterogeneous autoregressive model with exogenous predictors (HAR‐X) as its anchor, a train‐only masked representation of a high‐dimensional ...

Journal of Applied Econometrics, EarlyView.ABSTRACT We introduce EA‐MD‐QD, a new publicly available dataset comprising 1136 macroeconomic time series for the euro area (EA) and its ten largest member countries observed at monthly or quarterly frequency. Since January 2024, EA‐MD‐QD has been updated monthly and continuously revised, providing a valuable resource for policy analysis in the EA ...

Journal of Intelligent Medicine, EarlyView.Lightweight Motor Imagery BCI Decoding: From Structural Design to Model Compression. This graphical abstract summarizes the motivation, principal strategies, and deployment benefits of lightweight motor imagery brain–computer interface decoding. Structural‐level lightweight designs, including depthwise separable, multi‐branch, and dilated convolutions,

Pointwise multipliers for functions of bounded mean oscillation
Journal of the Mathematical Society of Japan, 1985 We characterize the set of pointwise multipliers on bmo\({}_{\phi}({\mathbb{R}}^ n)\), which generalizes the corresponding theorem by \textit{S. Janson} in the torus case [Ark. Mat. 14, 189-196 (1976; Zbl 0341.43005)]. To be more precise, let \(\phi\) (r) be a nondecreasing concave function on the positive real line, and \[ w(x,r)=\phi (r)/(|\int^{1}_ ...

The multiplier principle, credit-money and time [PDF]
We analyze the simple fiscal multiplier and extend it in terms of a credit-money framework and in terms of a time dimension, making it applicable to time series data.

Land Degradation &Development, EarlyView.ABSTRACT Rainfall‐induced physical crusting is associated with degradation of near‐surface soil structure, but its pore‐scale structural and mechanical evolution during drying remains poorly resolved. We combined time‐resolved X‐ray computed tomography (XCT), digital volume correlation (DVC), and surface‐aligned stratification to track pore ...
