Generalizing Gelatin Methacryloyl Granular Hydrogel Fabrication Using Stable Microgels with Predictable Stiffness

Advanced Healthcare Materials, EarlyView.
Gelatin methacryloyl (GelMA) granular hydrogel scaffolds (GHS) are fabricated using a generalized two‐step photocrosslinking approach to yield stable (non‐dissolving) microgels suitable for in situ covalent assembly under physiological conditions. A phase diagram is developed to define the interplay between individual microgel stability and scaffold ...

Comparative Analysis of Sequential and Combinatorial Auctions Based on Petri Nets

IEEE Access, 2018
An auction is a crucial resource allocation mechanism for a supply chain and includes the purchasing price at the winner's bid value, eligible suppliers in winning bidder sets, and business payment terms. A multi-object auction usually involves two types

Clustering for Petri nets

Theoretical Computer Science, 2003
AbstractThis work builds a bridge from •clustering techniques—merging neighbouring nodes which is a key feature for software engineering and the practical applications of Petri nets—to•folding techniques—merging only transitions with transitions and places with places, preserving behaviour and allowing theoretical connections to many models of ...

Silicon Nanowire Mats Enable Advanced Bioelectrical Recordings in Primary DRG Cell Cultures

Advanced Healthcare Materials, EarlyView.
SiNW mat‐based MEA (NW_MEA) enables continuous intracellular recordings from neurons in primary rat DRG cell cultures, identifying C‐fiber nociceptors. Supported by an astrocyte feeder layer, SiNW mat promotes DRG neuron and glial cell growth, preserving in vivo‐like cell characteristics and allowing drug‐modulated activity monitoring.

Inhibitor Petri Net that Executes an Arbitrary Given Markov Normal Algorithm

Моделирование и анализ информационных систем, 2011
The inhibitor Petri net with a fixed structure that executes an arbitrary given Markov normal algorithm was constructed. The algorithm and its input string are encoded by nonnegative integer numbers and put into dedicated places of the Petri net which ...

Combination of Polydopamine and Plasma Oxidation Increases Tissue Integration of Polyurethane‐Silicone Copolymers for Cardiovascular Implants

Advanced Healthcare Materials, EarlyView.
Plasma oxidation following polydopamine deposition can significantly reduce the surface hydrophobicity of polyurethane‐siloxanes without impacting surface roughness, thereby increasing fibroblast viability, adhesion, and extracellular matrix production and secretion.

A Deadlock Prevention Strategy for Petri Nets Through Tuning Time Constraints

IEEE Access
Deadlocks are of paramount importance in resource allocation systems, which are usually treated from the perspective of discrete event systems. This paper develops a deadlock prevention strategy for a system modeled with Petri nets, by endowing ...

Peptide Display Directed Assembly of Biopolymer Core–Silica Shell Particles

Advanced Healthcare Materials, EarlyView.
Bacterial cells are engineered to produce biopolyester particles displaying peptides mediating growth of silica. Peptide‐coated biopolyester particles are treated with silica precursors and silica shell formation is studied. Transmission electron microscopy shows silica‐coated BPs which are formed after the silicification treatment. Characterization of
