CHARGE syndrome with early fetal ear abnormalities: A case report
Clinical Case Reports, Volume 12, Issue 3, March 2024.Key Clinical Message CHARGE syndrome is a rare genetic disorder characterized by several distinct features. The presence of fetal ear abnormalities could be the early indicator of CHARGE syndrome. Subsequent prenatal diagnosis is essential to confirm the disorder.

Equine Veterinary Journal, Volume 56, Issue 2, Page 243-252, March 2024.Abstract Equine thyroid disorders pose a diagnostic challenge in clinical practice because of the effects of nonthyroidal factors on the hypothalamic–pituitary–thyroid axis, and the horse's ability to tolerate wide fluctuations in thyroid hormone concentrations and survive without a thyroid gland. While benign thyroid tumours are common in older horses,

Journal of Comparative Neurology, Volume 532, Issue 2, February 2024.Inmunohistochemical methods showed that GABAergic cells, fibers, and terminals are widely distributed throughout the brain and spinal cord of the sturgeon. Comparison among sturgeon and other vertebrates, revealed numerous differences in the complexity of specific subsystems reflecting different trends followed by vertebrate brains during evolution ...

Compact integral manifolds of differential systems [PDF]
arXiv, 2010 The boundedness tests for the number of compact integral manifolds of autonomous ordinary differential systems, of autonomous total differential systems, of linear systems of partial differential equations, of Pfaff systems of equations, and of systems of exterior differential equations are proved.

Using Structure-Behavior Coalescence Method for Systems Definition 2.0 [PDF]
arXiv, 2021 Systems definition is an artifact created by humans to describe what a system is. A system has been defined, by systems definition 1.0, hopefully to be an integrated whole, embodied in its components, their interrelationships with each other and the environment, and the principles and guidelines governing its design and evolution.

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 ...

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.
