Neural and Neurosecretory Control of the Decapod Crustacean Auxiliary Heart

open access: yes, 1979
An auxiliary heart is found in many decapod crustaceans at the anterior end of the dorsal median artery. A brief description of the anatomy is given here, followed by an exploration of the reflex and neurosecretory control.

Linearly repetitive Delone systems have a finite number of non periodic Delone system factors [PDF]

open access: yesarXiv, 2008
We prove linearly repetitive Delone systems have finitely many Delone system factors up to conjugacy. This result is also applicable to linearly repetitive tiling systems.

An Networked HIL Simulation System for Modeling Large-scale Power Systems [PDF]

open access: yesarXiv, 2020
This paper presents a network hardware-in-the-loop (HIL) simulation system for modeling large-scale power systems. Researchers have developed many HIL test systems for power systems in recent years. Those test systems can model both microsecond-level dynamic responses of power electronic systems and millisecond-level transients of transmission and ...

Current Concepts in the Field of Neurochemical Mediation [PDF]

open access: yes, 1969
Chemical mediators involved in the integrative activities of the nervous system operate either at close range as neurohumors or over some distance as neurohormones. As will become evident, the distinction between neurohumoral and neurohormonal activities

Integral equivalence of multidimensional differential systems [PDF]

open access: yesarXiv, 2009
The bases of the theory of integrals for multidimensional differential systems are stated. The integral equivalence of total differential systems, linear homogeneous systems of partial differential equations, and Pfaff systems of equations is established.

Inhibition of PaCaMKII-E isoform in the dorsal unpaired median neurosecretory cells of cockroach reduces nicotine- and clothianidin-induced currents [PDF]

open access: yes, 2014
Cellular responses to Ca(2+) require intermediary proteins such as calcium/calmodulin-dependent protein kinase II (CaMKII), which transduces the signal into downstream effects.

Fractional Multidimensional System [PDF]

open access: yesarXiv, 2017
The multidimensional ($n$-D) systems described by Roesser model are presented in this paper. These $n$-D systems consist of discrete systems and continuous fractional order systems with fractional order $\nu$, $0<\nu<1$. The stability and Robust stability of such $n$-D systems are investigated.

Afferent Neuronal Control of Type-I Gonadotropin Releasing Hormone Neurons in the Human. [PDF]

open access: yes, 2013
Understanding the regulation of the human menstrual cycle represents an important ultimate challenge of reproductive neuroendocrine research. However, direct translation of information from laboratory animal experiments to the human is often complicated ...

A microRNA Imparts Robustness against Environmental Fluctuation during Development [PDF]

open access: yes, 2009
The microRNA miR-7 is perfectly conserved from annelids to humans, and yet some of the genes that it regulates in Drosophila are not regulated in mammals.
