Dimensionality reduction of complex dynamical systems.
Tu C, D'Odorico P, Suweis S. Tu C, et al. iScience. 2020 Dec 9;24(1):101912. doi: 10.1016/j.isci.2020.101912. eCollection 2021 Jan 22. iScience. 2020. PMID: 33364591 Free PMC article.
We test our approach on a variety of real-world complex problems showing how this new framework can approximate the system's response to changes and correctly identify the regions in the parameter space corresponding to the system's transitions. Our wo …

The enigma of myelin-associated growth inhibitors in spontaneously regenerating nervous systems.
Sivron T, Schwartz M. Sivron T, et al. Trends Neurosci. 1994 Jul;17(7):277-81. doi: 10.1016/0166-2236(94)90056-6. Trends Neurosci. 1994. PMID: 7940760 Review.
However, it has now been demonstrated that spontaneously regenerating systems do contain growth inhibitors, though their levels seem to be lower than in nonregenerative systems. The main difference, however, appears to reside in the system's response t …

Health Systems, Aging, and Inequity: An Example from Chile.
Villalobos Dintrans P. Villalobos Dintrans P. Int J Environ Res Public Health. 2020 Sep 9;17(18):6546. doi: 10.3390/ijerph17186546. Int J Environ Res Public Health. 2020. PMID: 32916795 Free PMC article.
Considering this context, the question of how prepared the health system is to deal with these challenges arises; Methods: A framework to assess the health system's preparedness for aging was proposed, considering the health system's goals and f …

Dynamical diseases of brain systems: different routes to epileptic seizures.
Lopes da Silva FH, Blanes W, Kalitzin SN, Parra J, Suffczynski P, Velis DN. Lopes da Silva FH, et al. IEEE Trans Biomed Eng. 2003 May;50(5):540-8. doi: 10.1109/TBME.2003.810703. IEEE Trans Biomed Eng. 2003. PMID: 12769430 Review.
The transition between these two states can either occur: 1) as a continuous sequence of phases, like in some cases of mesial temporal lobe epilepsy (MTLE); or 2) as a sudden leap, like in most cases of absence seizures. In the mathematical terminology of nonlinear systems …

Observability of complex systems.
Liu YY, Slotine JJ, Barabási AL. Liu YY, et al. Proc Natl Acad Sci U S A. 2013 Feb 12;110(7):2460-5. doi: 10.1073/pnas.1215508110. Epub 2013 Jan 28. Proc Natl Acad Sci U S A. 2013. PMID: 23359701 Free PMC article.
A quantitative description of a complex system is inherently limited by our ability to estimate the system's internal state from experimentally accessible outputs. ...A system is called observable if we can reconstruct the system's comple …

Created Environment: Evolution of a Neuman Systems Model Concept.
McDowell BM, Beckman S, Fawcett J. McDowell BM, et al. Nurs Sci Q. 2023 Jan;36(1):89-91. doi: 10.1177/08943184221131975. Nurs Sci Q. 2023. PMID: 36571307
The most recent definition of created environment is offered in this essay as the following: The created environment is a synthesis of the internal and external environments that encompasses the client system's ever-changing awareness of the physiological, psycholog …

Analysing hierarchy in the organization of biological and physical systems.
Jagers op Akkerhuis GA. Jagers op Akkerhuis GA. Biol Rev Camb Philos Soc. 2008 Feb;83(1):1-12. doi: 10.1111/j.1469-185X.2007.00023.x. Biol Rev Camb Philos Soc. 2008. PMID: 18211280 Review.
A structured approach is discussed for analysing hierarchy in the organization of biological and physical systems. The need for a structured approach follows from the observation that many hierarchies in the literature apply conflicting hierarchy rules and include ill-defi …

Active Disturbance Rejection Control of Euler-Lagrange Systems Exploiting Internal Damping.
Ren C, Ding Y, Hu L, Liu J, Ju Z, Ma S. Ren C, et al. IEEE Trans Cybern. 2022 Jun;52(6):4334-4345. doi: 10.1109/TCYB.2020.3026190. Epub 2022 Jun 16. IEEE Trans Cybern. 2022. PMID: 33095733
In this article, a new ADRC framework is proposed by incorporating at a fundamental level the physical structure of the Euler-Lagrange (EL) systems. In particular, the differential feedback gain can be selected considerably small or even 0, due to the effective exploitatio …

Sustainable systems as organisms?
Ho MW, Ulanowicz R. Ho MW, et al. Biosystems. 2005 Oct;82(1):39-51. doi: 10.1016/j.biosystems.2005.05.009. Biosystems. 2005. PMID: 15985324
The healthy organism excels in maintaining its organisation and keeping away from thermodynamic equilibrium--death by another name--and in reproducing and providing for future generations. In those respects, it is the ideal sustainable system. We propose therefore to explo …

Response properties of self-improving systems.
Krakovsky A. Krakovsky A. J Chem Phys. 2016 Apr 7;144(13):134107. doi: 10.1063/1.4945423. J Chem Phys. 2016. PMID: 27059562
We observe that a sustained positivity (or negativity) of a system's second-order response will result in a directional change of the system's characteristics under the corresponding random exposure. We identify these changes with improvement (or decli …
