Measurement-based correlation approach for power system dynamic response estimation [PDF]

open access: yes, 2015
Understanding power system dynamics is essential for online stability assessment and control applications. Global positioning system-synchronised phasor measurement units and frequency disturbance recorders (FDRs) make power system dynamics visible and ...

Consciousness—a system-theoretical approach [PDF]

open access: yesFrontiers in Psychology, 2014
The aim of this work is not to compete with the paper by Boly et al. (2013), but rather to look at the issue of consciousness from a different, system-theoretical perspective. According to advice by Sokal and Bricmont that “it’s a good idea to know, what one is talking about” (Sokal and Bricmont, 1999, p.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

A relativistic positioning system exploiting pulsating sources for navigation across the Solar System and beyond [PDF]

open access: yes, 2011
We introduce an operational approach to the use of pulsating sources, located at spatial infinity, for defining a relativistic positioning and navigation system, based on the use of null four-vectors in a flatMinkowskian spacetime.

A Systemic Approach to Innovation

open access: yes, 2002
The context of this chapter is set by the contemporary transition from an industrial to a knowledge-based economy. OECD (1996a) has documented the way in which the knowledge-based economy of learning individuals, organisations and economies is emerging out of the machine-based economy that determined advanced economies in most of the time in the 20th ...

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the
