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.

Seasonal drivers of plant–soil–microbial community structure and functions in Western Himalayan grasslands, Pakistan

Grassland Research, EarlyView.
Plant species richness was greater in summer in both alpine and subalpine grassland ecosystems. Soil moisture demonstrates significant positive correlations with soil organic carbon and total nitrogen across seasonal periods. Microbial α‐diversity peaks during summer but maintains functional stability across seasons.

Limited Sensitivity of Ultrasound‐Guided Fine‐Needle Aspiration Cytology for Occult Nodal Metastases in Early‐Stage Oral Squamous Cell Carcinoma

Head &Neck, EarlyView.
ABSTRACT Background Ultrasound‐guided fine‐needle aspiration cytology (US‐FNAC) is commonly used in the diagnostic work‐up of head and neck cancer, but its ability to detect occult lymph node metastases in early‐stage oral squamous cell carcinoma (OSCC) with a clinically negative neck remains unclear.
