Intraday Functional PCA Forecasting of Cryptocurrency Returns

Journal of Forecasting, Volume 45, Issue 5, Page 2186-2212, August 2026.
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.

Speech and Language Markers of Bipolar Disorder: Challenges and Opportunities

Bipolar Disorders, Volume 28, Issue 5, August 2026.
ABSTRACT Background Clinicians aspire to predict the emergence of Bipolar Disorder (BD) in a timely manner. To accomplish this, markers reflecting mental states that can be gathered non‐invasively and at large scale are needed. Here, we systematically evaluate evidence relating speech‐based markers to mood states in BD.

Water Level Regulation Regime Shifts Drive Divergent Foraging Habitat Use by Wintering Hooded Cranes (Grus monacha) in Shallow Gate‐controlled Lakes of the Yangtze Floodplain

Ecology and Evolution, Volume 16, Issue 6, June 2026.
This study investigates how contrasting hydrological regulation regimes at two gate‐controlled lakes influence the foraging strategies of wintering Hooded Cranes. We demonstrate that while cranes at near‐natural sites follow Optimal Foraging Theory by utilizing high‐accessibility mudflats, those at artificially high‐water sites exhibit an adaptive ...
