Feline‐Inspired Robot Enabled by Combustion‐Driven Actuators for Agile Motion and High‐Payload Obstacle Traversal

open access: yesAdvanced Science, EarlyView.
Inspired by nature's competitive maneuvers, this study introduces a combustion‐driven soft actuator that powers a multi‐modal “Jump‐and‐Fly Catbot” (JFC). With millisecond response, high‐force output (over 70 times its weight) and precise control (error within 5%), the robot can jump, fly, hover, and escape from challenging environments, achieving ...

Benign Hyperostosis of the Rib

open access: yesJournal of the Belgian Society of Radiology
Teaching point: Benign hyperostosis of the rib is a benign entity consisting of a stress phenomenon that should not be confused with Paget, fibrous dysplasia, or osteoblastic metastasis.

Lattice Genome Framework for Regionally Tailored Component‐Level Multi‐Objective Design in Additive Manufacturing

open access: yesAdvanced Science, EarlyView.
A Lattice Genome framework links geometric and process “genes” to lattice “phenotypes” via correction‐calibrated high‐throughput simulations and a growing performance database. Genome‐driven retrieval and recombination of unit cells enables component‐level, regionally tailored multi‐objective design: stress fields are programmed under constant relative

Aneurysmal rib cyst

open access: yesMonaldi Archives for Chest Disease, 2017
<p>Thoracic cage is the site of development of various primary or metastatic tumors. An aneurysmal rib cyst is a benign tumor arising from the chest wall. Aneurysmal rib cyst is considered a rare surgical entity and its presence must be followed by removal for histology examination. We present here the case of an aneurysmal rib cyst to a young 33-

Development‐based In Vivo Bioreactor Strategy for Challenging Senescent Bone Reconstruction

open access: yesAdvanced Science, EarlyView.
We present a development‐based in vivo bioreactor strategy to generate rejuvenated bone grafts (vBR‐Bone) within aged hosts. By enclosing vBR‐Bone fragments within an asymmetric biomimetic periosteum, segmental femoral defects in aged mice were successfully repaired within 6 weeks. Mechanistically, the multifactors of vBR‐Bone reconstitute a remodeling

Technical Challenges in the Construction of Gothic Vaults: The Gothic Theory of Structural Design [PDF]

open access: yes, 2012
The construction of a Gothic vault implied the solution of several technical challenges. The literature on Gothic vault construction is quite large and its growth continues steadily.

Smart Optogenetics for Real‐Time Automated Control of Cardiac Electrical Activity

open access: yesAdvanced Science, EarlyView.
We are able to stop dangerous heart‐rhythm spirals before they fully form. Within about 100 ms, it pinpoints the spiral's tiny central tip (≈0.9 mm) using light‐based sensing and machine learning, then shines targeted light to shut it down. This fast, precise, closed‐loop approach detects, targets, and terminates arrhythmias in real time.
