An Organ‐on‐Chip Platform for Strain‐Controlled, Tissue‐Specific Compression of Cartilage and Mineralized Osteochondral Interface to Study Mechanical Overloading in Osteoarthritis

open access: yesAdvanced Healthcare Materials, EarlyView.
A mechanically active OsteoChondral Unit (OCU)‐on‐Chip platform mimicking the OCU's functional anatomy and the strain gradient across the osteochondral interface is presented. Upon compartment‐specific hyperphysiological compression, the model replicates mechanisms observed in osteoarthritis (OA) progression, such as calcium crystal accumulation ...

Photocrosslinkable Kidney Decellularized Extracellular Matrix‐Based Bioink for 3D Bioprinting

open access: yesAdvanced Healthcare Materials, EarlyView.
A photocrosslinkable bioink is developed from methacrylated decellularized porcine kidney extracellular matrix to create kidney‐specific 3D constructs. This bioink supports high cell viability, promotes multicellular spheroid formation, and enables stable multilayer bioprinting with tunable mechanical properties, providing a versatile platform for ...

Validation of Petri Net Models by ‘Petri-Net-Machine’

open access: yesIFAC Proceedings Volumes, 1986
Abstract The successful application of Petri nets for system specification has produced the call for software tools which as a part of CAD-systems may be used to prove the correctness of the specification . ‘Petri-Net-Machine’ is the first tool of this kind which runs on microcomputers .

Acceleration for Petri Nets [PDF]

open access: yes, 2013
The reachability problem for Petri nets is a central problem of net theory. The problem is known to be decidable by inductive invariants definable in the Presburger arithmetic. When the reachability set is definable in the Presburger arithmetic, the existence of such an inductive invariant is immediate.

Engineering a Human‐Sized Common Bile Duct Prototype with Regenerative Potential: In Vitro Evaluation of Mechanics, Function, Degradation, and Immune Modulation

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents a multiphasic bile duct construct composed of biocompatible materials and cells, featuring an inner layer that supports biliary epithelium growth, a middle layer providing mechanical strength, and an outer cell‐permissive layer designed to support future in vivo integration.
