Blockwise Joint Conformal Prediction for Simultaneous Multi-Component Condition Monitoring of Hydraulic Systems

This paper proposes a blockwise joint conformal prediction framework that calibrates prediction sets over operational blocks rather than individual components, demonstrating on hydraulic system data that this approach achieves significantly higher simultaneous coverage for multi-component states compared to conventional marginal methods, albeit with backbone-dependent set sizes and strict reliance on exchangeability assumptions.

Methods Used in Developing the Adaptive Design Extension of the DELTA² Checklist for Enhancing Sample Size Reporting in Trial Grant Applications and Protocols

This paper describes the systematic development of the AD-DELTA2 checklist, an expert-endorsed extension of the DELTA2 guidance created through a multi-stage process of evidence review, Delphi surveys, and consensus meetings to improve the transparency and reproducibility of sample size reporting in adaptive design trial grant applications and protocols.

Polynomial-Time Exact Relabeling Fragility Analysis for Empirical Additive Treatment-by-Modifier Interactions

This paper presents an exact polynomial-time algorithm that computes the minimum cost of binary modifier-label changes required to alter the sign of an empirical additive treatment-by-modifier interaction, while explicitly clarifying that the method addresses a specific computational instance without establishing broader causal robustness or runtime superiority.

Measuring Visibility Bias in Digital Urban Experience: A Multimodal Spatial Statistical Analysis of Sina Weibo Data in Guangzhou

This study introduces a bias-aware spatial statistical framework using 273,566 geotagged Sina Weibo posts to quantify and map the uneven digital visibility of Guangzhou's urban categories, revealing that while emotional visibility is scale-dependent, architectural visibility exhibits consistent spatial clustering across modern and historic districts.

Bridging SCED and Group Designs: Demonstrating the Ratio-Metric BC-IRR Effect Size in a Meta-Analysis

This study introduces the ratio-metric BC-IRR effect size as a method to bridge single-case and group experimental designs, demonstrating through a reanalysis of technology-aided interventions for students with autism that BC-IRR offers distinct interpretive advantages over traditional metrics while enabling the synthesis of diverse evidence types.
