P1.114. Endoscopic Diagnosis of Esophageal Cancer Using Ultra-High Magnification Endocytoscopy

Abstract Topic Esophageal Cancer: New Diagnostic Modalities (Including PET, PET-CT, New Tracers) Background Background Ultra-high magnification endoscopic observation using endocytoscopy (EC) enables cellular-level visualization and allows in vivo assessment comparable to histopa...

Derivation of human post-mitotic cardiomyocytes from tetraploid iPSCs

Human induced pluripotent stem cell (iPSC)-derived cardiomyocytes (iPS-CMs) have great potential in regenerative medicine. However, iPS-CMs are immature and resemble fetal cardiomyocytes, restricting their application. Fetal cardiomyocytes in the human heart are diploid and proli...

Exergy analysis on daylighting with a single-paned glass window and PV-based electric lighting

This study aims to evaluate two representative pathways for utilizing solar radiation in a building for indoor lighting using exergy analysis: (1) direct daylight utilization through a window system and (2) indirect utilization through electric lighting powered by photovoltaic (P...

A hydro-mechanical mechanism for cyclic ratcheting of embedded cantilever retaining walls in saturated sand

Saturated backfills behind embedded cantilever walls deform through coupled hydro-mechanical processes that pseudo-static methods cannot capture. Three 40 g dynamic centrifuge tests are presented to isolate how the pre-seismic static state, set by wall flexural stiffness, togethe...

Molecular dynamics study on anisotropic water cluster formation in polyethylene: A fundamental perspective on water tree initiation

The microscopic mechanisms of water tree inception in polymeric insulating materials remain a critical challenge for high-voltage engineering. In this study, molecular dynamics simulations were employed to investigate the structural and kinetic responses of water nanoclusters in...
