Intertwined bulk photocarrier and interfacial barrier dynamics in van der Waals point-contact Schottky junctions

Abstract Schottky junctions based on transition-metal dichalcogenides underpin next-generation optoelectronic devices, yet the nanoscale carrier dynamics that ultimately govern their performance remain largely inaccessible. Here, we employ optical pump–probe time-resolved atomic...

Power With Confounders in Clinical Trials Using External Controls

ABSTRACT When the number of patients is limited in clinical trials for rare diseases and pediatric developments, enrolling sufficient participants for confirmatory randomized clinical trials is difficult. Alternative trial designs using external controls have been proposed: augme...

Applying Non-Negative Matrix Factorization with Covariates to the Longitudinal Data as Growth Curve Model

Using Non-negative Matrix Factorization (NMF), an observed matrix is approximated by a basis matrix times a coefficient matrix. When each individual’s coefficient vector is explained by covariates, the coefficient matrix factorizes into a parameter matrix and a covariate matrix—a...

Disentangling large-scale supply networks: f-HiCoNE framework for flow-hierarchical clustering via combinatorial Hodge decomposition

Abstract Modern society relies on complex supply chains to sustain the flow of goods and services that are essential to daily life. While traditional supply chain theory assumes a clear, hierarchical flow from upstream suppliers to downstream customers, observable real-world tran...

Fatty acid signatures distinguish autotrophy, partial mycoheterotrophy, and full mycoheterotrophy in angiosperms

Abstract Detecting partial mycoheterotrophy in green plants remains challenging, particularly in associations with arbuscular mycorrhizal (AM) or rhizoctonia fungi, because natural-abundance stable isotope patterns often provide limited diagnostic resolution in these systems. We...

Feasibility to detect rapid change and disappearance of seagrass: Lessons from nearly 80 years of vegetation change in the Ako, Seto Inland Sea, Japan

Abstract. Seagrass meadows provide essential ecosystem services but are declining globally, creating an urgent need for continuous monitoring and management. However, the high cost of commercial satellite imagery and field surveys limits sustained observation, highlighting the ne...
