Length of the Adult Human Colon in Health and Constipation Measured Using Magnetic Resonance Imaging

open access: yesNeurogastroenterology &Motility, EarlyView.
Colon length was measured in adult healthy volunteers, people with chronic constipation, and people with IBS with constipation using MRI. Colon length is significantly longer in chronic constipation. The chronically constipated colon is unable to accommodate longitudinally in response to fluid influx from a macrogol challenge.

CP_SDUNet: road extraction using SDUNet and centerline preserving dice loss

open access: yesIAES International Journal of Robotics and Automation (IJRA)
<span lang="EN-US">Existing automatic road map extraction approaches on remote sensing images often fail because they cannot understand the spatial context of an image. Mainly because they could not learn the spatial context of the image and only knew the structure or texture of the image.

Global Hydroclimatic Controls on Multithread River Dynamics

open access: yesAGU Advances, Volume 7, Issue 2, April 2026.
Abstract Most large rivers in densely populated areas split flow into multiple channels, forming interconnected pathways called threads. Multithread rivers are sensitive to hydroclimatic changes, yet understanding their dynamics is challenging due to the lack of robust metrics to characterize their evolution.

Adaptable Tile‐Based Pneumatic Origami through Structurally Coupled Localized Actuation

open access: yesAdvanced Engineering Materials, Volume 28, Issue 5, 4 March 2026.
This article presents tile‐based pneumatic origami structures with rigid tiles and flexible fabric creases, achieving adaptable properties including morphing shape, selective multistability, and tunable stiffness. Independently pressurized folding bladders at each crease enable structurally coupled localized actuation of origami structures.
