Deep Underground Science and Engineering, EarlyView.This paper presents temporal and adaptive‐frequency network with MixStyle (TAMNet), a deep time‐series modeling framework for accurate and robust multi‐well oil productivity forecasting. TAMNet integrates transformer and long short‐term memory architectures to capture both short‐ and long‐term temporal dependencies, enhanced by a temporal gate unit ...

Pointwise Multipliers of Triebel-Lizorkin Spaces on Carnot-Carathéodory Spaces [PDF]
Journal of Function Spaces and Applications, 2012 Summary: Let \((\mathcal X, d, \mu)\) be a Carnot-Carathéodory space, namely, \(\mathcal X\) is a smooth manifold, \(d\) is a control, or Carnot-Carathéodory, metric induced by a collection of vector fields of finite type. \(\mu\) is a nonnegative Borel regular measure on \(\mathcal X\) satisfying that there exists a constant \(C_0 \in [1, \infty ...

Intraday Functional PCA Forecasting of Cryptocurrency Returns
Journal of Forecasting, EarlyView.ABSTRACT We study the functional PCA (FPCA) forecasting method in application to functions of intraday returns on Bitcoin. We show that improved interval forecasts of future return functions are obtained when the conditional heteroscedasticity of return functions is taken into account.

Characterizations of pointwise multipliers of Besov spaces in endpoint cases with an application to the duality principle [PDF]
Let p, q∈(0, ∞], s ∈R, and M(Bsp,q(Rn))denote the pointwise multiplier space of the Besov space Bsp,q(Rn). In this article, the authors first establish the characterizations of both (Bs1,∞(Rn))with s ∈R \{0}and M(Bs∞,1(Rn))with s ∈(−∞, 0].

Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT This paper develops a mathematical framework for interpreting observations of solar inertial waves in an idealized setting. Under the assumption of purely toroidal linear waves on the sphere, the stream function of the flow satisfies a fourth‐order scalar equation.
