Morphisms of Networks of Hybrid Open Systems [PDF]
arXiv, 2019 This thesis (defended 10/07/2019) develops a theory of networks of hybrid open systems and morphisms. It builds upon a framework of networks of continuous-time open systems as product and interconnection. We work out categorical notions for hybrid systems, deterministic hybrid systems, hybrid open systems, networks of hybrid open systems, and morphisms

Contraction analysis of time-varying DAE systems via auxiliary ODE systems [PDF]
arXiv, 2023 This paper studies the contraction property of time-varying differential-algebraic equation (DAE) systems by embedding them to higher-dimension ordinary differential equation (ODE) systems. The first result pertains to the equivalence of the contraction of a DAE system and the uniform global exponential stability (UGES) of its variational DAE system ...

Dendritic Peptide Release Mediates Interpopulation Crosstalk between Neurosecretory and Preautonomic Networks [PDF]
, 2013 SummaryAlthough communication between neurons is considered a function of the synapse, neurons also release neurotransmitter from their dendrites. We found that dendritic transmitter release coordinates activity across distinct neuronal populations to ...

First integrals of ordinary linear differential systems [PDF]
arXiv, 2012 The spectral method for building first integrals of ordinary linear differential systems is elaborated. Using this method, we obtain bases of first integrals for linear differential systems with constant coefficients, for linear nonautonomous differential systems integrable in closed form (algebraic reducible systems, triangular systems, the Lappo ...

Complex Systems + Systems Engineering = Complex Systems Engineeri [PDF]
arXiv, 2006 One may define a complex system as a system in which phenomena emerge as a consequence of multiscale interaction among the system's components and their environments. The field of Complex Systems is the study of such systems--usually naturally occurring, either bio-logical or social.

Systems of quotients of Lie triple systems [PDF]
Communications in Algebra, 42(2014)(8), 3339-3349, 2013 In this paper, we introduce the notion of system of quotients of Lie triple systems and investigate some properties which can be lifted from a Lie triple system to its systems of quotients. We relate the notion of Lie triple system of Martindale-like quotients with respect to a filter of ideals and the notion of system of quotients, and prove that the ...

Cephalopod Brains: An Overview of Current Knowledge to Facilitate Comparison With Vertebrates. [PDF]
, 2018 Cephalopod and vertebrate neural-systems are often highlighted as a traditional example of convergent evolution. Their large brains, relative to body size, and complexity of sensory-motor systems and behavioral repertoires offer opportunities for ...

State of the body in disorders of diurnal physiological rhythms and long-term hypokinesia [PDF]
In order to study the effects of hypokinesia and circadian rhythm restructuring on the morphological and functional status of the hypothalamo-hypophysic-adrenal system, young male Wistar rats were placed in small cages for varying periods.

Neurological endocrinology: the coordinating mechanism [PDF]
, 1984 The nervous and endocrine systems are integrative in nature for they provide th'e organism with sophisticated external and internal sensing devices which feed information into the central nervous system for appropriate responses of the target ...

Neuropeptides isotocin and arginine vasotocin in urophysis of three fish species [PDF]
, 2012 In this study, for the first time, both neuropeptides isotocin (IT) and arginine vasotocin (AVT) have been identified and measured in urophysis, the neurohaemal organ of the caudal neurosecretory system of teleost fish.
