Holistic bone developing microenvironment engineered apoptotic extracellular vesicles recapitulate multidimensional developmental signatures in adult and senile bone repair

open access: yesInterdisciplinary Medicine, EarlyView.
The developing bone was identified as an M2a‐like macrophage driven immune microenvironment with multidimensional developmental signatures. hME‐ApoEVs were successfully fabricated via stimulating the M2a‐like developing microenvironment in vitro and confirmed its recapitulation of developmental features.

PERFORMANCE MODELING OF E-PROCUREMENT WORKFLOW USING GENERALISED STOCHASTIC PETRI NET (GSPN)

open access: yesJournal of ICT, 2022
This paper proposes a Generalised Stochastic Petri net (GSPN) model representing a generic e-procurement workflow process. The model displays the dynamic behaviour of the system and shows the inter relationship of process activities.

Formal Approach to Safety‐Driven Dynamic Procedure Modeling

open access: yesSystems Engineering, EarlyView.
ABSTRACT Ensuring the safety of unmanned aerial systems (UAS) is a growing concern as the number of UAS grows increasingly fast. Regulatory bodies are in the process of tackling this problem by issuing standards and recommendations to be met by UAS designers.

Petri nets for systems and synthetic biology [PDF]

open access: yes, 2008
We give a description of a Petri net-based framework for modelling and analysing biochemical pathways, which uni¯es the qualita- tive, stochastic and continuous paradigms.

Integration of a failure monitoring within a hybrid dynamic simulation environment [PDF]

open access: yes, 2008
The complexity and the size of the industrial chemical processes induce the monitoring of a growing number of process variables. Their knowledge is generally based on the measurements of system variables and on the physico-chemical models of the process.

A Bibliometric Analysis of Process Mining

open access: yesWIREs Data Mining and Knowledge Discovery, Volume 16, Issue 2, June 2026.
Process mining studies with numbers. ABSTRACT Process mining (PM) has emerged as a pivotal discipline in data science, bridging traditional process analysis with data‐driven techniques to extract actionable insights from event logs. This study conducts a comprehensive bibliometric analysis of 1764 peer‐reviewed articles from the Web of Science database

Greater Thermal Plasticity Toward Heterogeneous Range‐Edge Environments of Three Hypericum Species

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Predictions from the highest‐ranked models testing the effect of range position (RP) and environmental heterogeneity (EH) on trait plasticity, with population‐specific plasticity values in blue (Hypericum montanum), red (H. perforatum), and green (H. maculatum).

Direction and Progression of Thermal Acclimation Effects on Ciliated Protist Populations Both Depend on Direction of Thermal Change

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Previous research has demonstrated that acclimation can have positive or negative effects on population growth rates in variable thermal environments, depending on the amount of time acclimation takes. A clear picture of the timescale of acclimation may help identify the consequences of various frequencies of thermal fluctuations for population ...

Stochastic High-level Petri Nets and Applications

open access: yesIEEE Transactions on Computers, 1988
A class of stochastic Petri nets called stochastic high-level Petri nets (SHLPNs) is proposed. SHLPNs are high-level Petri nets augmented with exponentially distributed firing times. SHLPNs generally lead to models with a smaller state space. A computer marking concept is introduced that allows a considerable reduction of the number of states and ...
