Feasibility of Transcatheter Aortic Valve Replacement After Surgical Aortic Valve Replacement With and Without Aortic Root Enlargement, Gated CT Study

open access: yes
BackgroundThe feasibility of valve-in-valve transcatheter aortic valve replacement (ViV-TAVR) after surgical aortic valve replacement (SAVR) and the impact of aortic root enlargement (ARE) remain unclear. This study assesses the anatomical feasibility of

Programmable Pneumatic Actuator System for a Bioinspired Artificial Colon

open access: yesAdvanced Materials Technologies, EarlyView.
A modular soft robotic colon simulator driven by programmable pneumatic actuation is developed to mimic physiological and pathological‐like motility patterns of the large intestine. Finite element–guided design and distributed control enable anatomically realistic deformation for peristalsis, segmentation, and mass movements, supporting capsule ...

UCST‐Driven Shape Morphing in Digital Light Processing 4D‐Printed Hydrogels

open access: yesAdvanced Materials Technologies, EarlyView.
A DLP‐printable UCST hydrogel based on poly(acrylic acid‐co‐acrylamide) enables reversible thermally induced expansion and 4D shape morphing. Rational control of composition, porosity, and multimaterial architecture enables predictable 4D shape morphing through differential swelling and localized actuation, opening new opportunities for high‐resolution

Chiral Porphyrin Monolayers on Ferromagnetic Thin Films: Ultrafast Spectroscopy of Hybrid Interfaces

open access: yesAdvanced Optical Materials, EarlyView.
Chiral porphyrin–oligopeptide monolayers covalently bound to Au‐capped Co/Ni multilayers form surface‐parallel J‐type aggregates and exhibit measurable singlet‐state transient absorption despite monolayer coverage. Femtosecond pump–probe spectroscopy reveals strong excited‐state quenching at the metal interface, yet no long‐lived charge‐transfer ...

Aortic valve replacement and concomitant right coronary artery bypass grafting performed via a right minithoracotomy approach

open access: yes, 2014
We present our experience of concomitant right coronary artery bypass grafting (CABG) and aortic valve replacement performed via a right minithoracotomy in patients with coronary lesions not amenable to percutaneous intervention.

Auto‐Routing Fluidic Printed Circuit Boards

open access: yesAdvanced Robotics Research, EarlyView.
This work introduces (STREAM) software tool for routing efficiently advanced macrofluidics, an open‐source software tool for automating the design of 3D‐printable fluidic circuit boards. STREAM streamlines tube routing and layout, enabling the rapid fabrication of fluidic networks for soft robotics, lab‐on‐a‐chip devices, microfluidics, and biohybrid ...

Midterm outcomes of concomitant ascending aorta replacement with rapid deployment aortic valve replacement

open access: yesJournal of Thoracic Disease
Aortic valve replacement (AVR) frequently accompanies concomitant ascending aorta replacement. This study was conducted to evaluate the early and midterm outcomes of patients who underwent AVR with rapid-deployment valve (RDAVR) and concomitant ascending aorta replacement compared to those who underwent isolated RDAVR.From June 2016 to June 2023, 130 ...

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

open access: yesAdvanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

ChicGrasp: Imitation‐Learning‐Based Customized Dual‐Jaw Gripper Control for Manipulation of Delicate, Irregular Bio‐Products

open access: yesAdvanced Robotics Research, EarlyView.
Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...
