A Technique for the Generation of Mucosal and Acral Melanoma Cell Lines

open access: yesPigment Cell &Melanoma Research, Volume 39, Issue 5, September 2026.
Simplified steps to establish acral or mucosal melanoma cell lines. ABSTRACT Mucosal and acral melanomas are rare subtypes of melanoma with unique clinical and biological features. A dearth of well‐established and characterized melanoma cell lines that reflect rare subtypes impedes research on these lethal diseases.

Functorial Models for Petri Nets [PDF]

open access: yes, 2001
We show that although the algebraic semantics of place/transition Petri nets under the collective token philosophy can be fully explained in terms of strictly symmetric monoidal categories, the analogous construction under the individual token philosophy

Arabidopsis STN7/STN8 alleviates oxidative damages via different regulatory patterns under drought stress

open access: yesThe Plant Journal, Volume 127, Issue 5, September 2026.
SUMMARY STN7 and STN8 kinases phosphorylate several proteins of the photosynthetic apparatus in response to changes in environmental conditions. Phosphorylation is linked to the dynamic arrangement of both the 3D structure of the thylakoid membrane and thylakoid protein complexes, thereby controlling excitation energy transfer between photosystems and ...

Localization and Navigation for Autonomous Mobile Robots Using Petri Nets in Indoor Environments

open access: yesIEEE Access, 2018
In this paper, mobile robotics and present tools used in localization, mapping, and navigation of a mobile robot are discussed. The main purpose of this paper is, given a map represented by the incidence matrix of a petri net (PN), to evaluate the use of

Epinephrine Enhances Virulence‐Associated Traits of Vibrio alginolyticus and Increases Mortality in Sciaenops ocellatus (Linnaeus, 1766)

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Stress hormones released during aquaculture handling and environmental disturbances can influence host–pathogen interactions, yet their effects on marine bacterial pathogens remain largely unexplored. This study examined how the stress hormone epinephrine affects the virulence of Vibrio alginolyticus isolated from diseased red drum (Sciaenops ...

Functorial Semantics for Petri Nets under the Individual Token Philosophy [PDF]

open access: yes, 1999
Although the algebraic semantics of place/transition Petri nets under the collective token philosophy has been fully explained in terms of (strictly) symmetric (strict) monoidal categories, the analogous construction under the individual token philosophy

Scheduling of Crude Oil Operations in Refinery without Sufficient Charging Tanks Using Petri Nets

open access: yesApplied Sciences, 2017
A short-term schedule for crude oil operations in a refinery should define and sequence the activities in detail. Each activity involves both discrete-event and continuous variables.

A Versatile Microfluidic Extrusion‐Based Hydrogel Platform for Self‐Organization and Long‐Term Maintenance of Engineered 3D Lymphatic Endothelium

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 25, 3 July 2026.
Microfluidic coaxial extrusion generates size‐controlled 3D lymphatic tubes from primary human dermal lymphatic endothelial cells in a defined four‐component matrix. These engineered vessels self‐organize into stable lymphatic endothelium, maintain selective macromolecular permeability for 30 days, and enable direct comparison with blood endothelial ...

A Petri-Net-Based Model for the Mathematical Analysis of Multi-Agent Systems [PDF]

open access: yes, 2001
Agent technology is widely recognized as a new paradigm for the design of concurrent software and systems. The aim of this paper is to give a mathematical foundation for the design and the analysis of multi-agent systems by means of a Petri-net-based ...

Cooperation of agents in complex systems based on supervision

open access: yesCybernetics and Information Technologies, 2014
Complex systems consist of many cooperating devices. To have a transparent view on the system structure, as well as on the structural interconnections and cooperation of the subsystems, it is useful to synthesize the complex systems systematically in a ...
