A Multi-Stage Decomposition and Hybrid Statistical Framework for Time Series Forecasting
AxiomsModeling and forecasting nonstationary and nonlinear economic time series remain fundamentally challenging due to structural breaks, volatility clustering, and noise contamination that distort the intrinsic stochastic structure.

Defining a trend for time series using the intrinsic time-scale decomposition
New Journal of Physics, 2014 We propose criteria that define a trend for time series with inherent multi-scale features. We call this trend the tendency of a time series. The tendency is defined empirically by a set of criteria and captures the large-scale temporal variability of ...

Advanced Functional Materials, EarlyView.We present a tissue‐stimulator platform for seamless electrode integration with pancreatic tissue, applying uniform electrical stimulation through optimized design with biohybrid 3D printing. Advantageous effects of electrical stimulation on β‐cell function were observed, including enhanced calcium signaling, islet morphology, and maturation.

Advanced Functional Materials, EarlyView.This work presents a rate‐adaptive site transformation strategy in Ag‑ethylenediamine intercalated Co9S8, which not only enables parallel water dissociation and H* adsorption, but also allows the catalyst to provide more active sites under high demand, removing a major bottleneck. The catalyst achieves a record current density of 4.2 A cm−2@2.0 V, with

Atomic Layer Deposition in Transistors and Monolithic 3D Integration
Advanced Functional Materials, EarlyView.Transistors are fundamental building blocks of modern electronics. This review summarizes recent progress in atomic layer deposition (ALD) for the synthesis of two‐dimensional (2D) metal oxides and transition‐metal dichalcogenides (TMDCs), with particular emphasis on their enabling role in monolithic three‐dimensional (M3D) integration for next ...
