Theoretical Computer Science, 1984 AbstractA class of Petri nets, called normal Petri nets, is introduced, and it is shown that, for each initial marking, the reachability set of a normal marked Petri net is an effectively computable semilinear set. More generally, we show that the reachability set of a marked Petri net is an effectively computable semilinear set unless the total number

Advanced 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 ...

Science of Computer Programming, 2015 We study Lending Petri nets, an extension of Petri nets where places may carry a negative number of tokens. This allows for modeling contracts where a participant may promise to give some of her resources under the guarantee that some other resources will eventually be obtained in exchange.

Transformation of Business Process Model and Notation models onto Petri nets and their analysis
Advances in Mechanical Engineering, 2018 Business Process Model and Notation is known as a widely used standard for business processes modeling. However, its main drawback is that it lacks formal semantics, leading to some undesirable properties, such as livelocks and deadlocks, such that it ...

Printing and Rerouting of Elastic and Protease Responsive Shape Memory Hydrogel Filaments
Advanced Healthcare Materials, EarlyView.A biofabrication strategy, Rerouting of Free‐Floating Suspended Hydrogel Filaments (REFRESH), is developed enabling the printing of highly elastic, reconfigurable protease‐responsive hydrogel filaments with shape memory properties. The filaments can be manually braided, knotted, and rerouted to create intricate cell‐laden 3D architectures, expanding ...
