VSM growth is stimulated in sympathetic neuron/VSM cocultures: role of TGF-β2 and endothelin
American Journal of Physiology-Heart and Circulatory Physiology, 2000Sympathetic nerves are purported to stimulate blood vessel growth. The mechanism(s) underlying this stimulation has not been determined. With use of an in vitro coculture model, the present study tests the hypothesis that sympathetic neurons stimulate the growth of vascular smooth muscle (VSM) and evaluates potential mechanisms mediating this ...

Vibrating Sample Magnetometer (VSM)
Vibrating Sample Magnetometer (VSM) is a powerful tool for characterizing magnetic properties of crystals. Its sensitivity and versatility make it particularly suitable for differentiating anisotropic properties in single crystals of magnetic materials.G. Senthil Murugan, J. Khatua

Observing experiences with the VSM
Kybernetes, 2004This paper offers a senior manager's reflections on experiences with the viable system model (VSM) in different situations of its application. These reflections are based on second‐order observation; that is on observing the forms of first‐order distinctions. Recently, systems thinking developed by Niklas Luhmann serves as an epistemological background.

Endothelial integrity is critical in mitigating a vicious cascade of secondary injuries following acute ischemic stroke (AIS). Matrix metalloproteinase-9 (MMP-9), a contributor to endothelial integrity loss, is elevated during stroke and is associated with worsened stroke outcome.

Epistemological considerations of VSM case studies
Proceedings of 2011 IEEE International Conference on Grey Systems and Intelligent Services, 2011In this paper I discuss key concepts that explain case studies which use the Viable System Model (Beer, 1979, 1981, 1985). I will first explain the idea of organisation, then explore the concept of communications, in particular communications between autonomous systems, and finally I'll discuss the idea of structural embodiment of policies supported by

Extended-VSM: a top-down approach for building simulation models through VSM
2019The speed of transformation of today's industrial world increasingly requires the development of simple and flexible tools capable of effectively supporting the decision-making process. In fact, corporate leaders interface daily with the need to quickly choose optimal configurations for their processes.

The Vacuum Shear Model (VSM) proposes that the rate of proper time is influenced not only by metric curvature, as described by General Relativity, but also by spatial variations in the shear state of the quantum vacuum. In this framework, vacuum shear defines a small dimensionless correction to local time flow, producing detectable signatures on ...
