Design and Experimental Study of Pressure Maintenance and Temperature Control System for Hydrate Pressure Core Processing Device

Energy Science &Engineering, EarlyView.
This paper presents a hydrate pressure core processing device integrated with a high‐precision active control system to perform nondestructive transfer, cutting, and analysis. To address the limitations of slow dynamic response and high thermal inertia in traditional passive systems, a differentiated control scheme is implemented.

Point and Risk estImation Using an enSemble of Models for Nowcasting: PRISM‐Now

Journal of Forecasting, EarlyView.
ABSTRACT We propose PRISM‐Now, a novel ensemble forecasting system for near‐term GDP projection. Recognizing that relevant economic information evolves over time, we treat forecasts from multiple base models as draws from a mixture distribution of “good” and “bad” estimates, whose composition changes continuously and cannot be identified ex ante.

Clinical Validation of Four Point‐of‐Care High‐Risk HPV Assays, Including Two Reduced‐Valency Assays, for Cervical Cancer Screening in Low‐Resource Settings

International Journal of Cancer, EarlyView.
High‐risk human papillomavirus (hrHPV) testing improves cervical cancer screening by facilitating earlier detection and prevention. In low‐resource settings, however, cost and increased referrals limit its use. At the same time, many new and more affordable assays lack validation.
