The regulatory mechanism of the male accessory reproductive gland (ARG) of Serinetha augur (Fabr) (Heteroptera: Coreidae)—A cotton pest [PDF]

open access: yes, 1994
The present study deals with the interrelationship of the neuroendocrine complex (NEC) and male accessory reproductive gland (ARG) of a cotton bug, Serinetha augur.

Confocal analysis of nervous system architecture in direct-developing juveniles of Neanthes arenaceodentata (Annelida, Nereididae) [PDF]

open access: yes, 2010
Background: Members of Family Nereididae have complex neural morphology exemplary of errant polychaetes and are leading research models in the investigation of annelid nervous systems.

Equivariant Filter Design for Kinematic Systems on Lie Groups [PDF]

open access: yesarXiv, 2020
It is known that invariance and equivariance properties for systems on Lie groups can be exploited in the design of high performance and robust observers and filters for real-world robotic systems. This paper proposes an analysis framework that allows any kinematic system on a Lie group to be embedded in a natural manner into an equivariant kinematic ...

Exposure to extremely low frequency (50 Hz) electromagnetic field changes the survival rate and morphometric characteristics of neurosecretory neurons of the earthworm Eisenia foetida (Oligochaeta) under illumination stress [PDF]

open access: yes, 2013
An in vivo model was set up to establish the behavioral stress response (rate of survival) and morphometric characteristics of A1 protocerebral neurosecretory neurons (cell size) of Eisenia foetida (Oligochaeta) as a result of the synergetic effect of

Neuromuscular organization of the benthic ctenophore, Vallicula multiformis

open access: yesZoological Letters
Ctenophora is the earliest metazoan taxon with neurons and muscles. Recent studies have described genetic, physiological, and cellular characteristics of the neural and muscular systems of this phylogenically important lineage.

Circadian clocks in crustaceans: identified neuronal and cellular systems.

open access: yesFrontiers in Bioscience, 2010
Circadian rhythms are known for locomotory and reproductive behaviours, and the functioning of sensory organs, nervous structures, metabolism and developmental processes.

A role of corazonin receptor in larval-pupal transition and pupariation in the oriental fruit fly Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) [PDF]

open access: yes, 2017
Corazonin (Crz) is a neuropeptide hormone, but also a neuropeptide modulator that is internally released within the CNS, and it has a widespread distribution in insects with diverse physiological functions.

Differential Changes in Expression of Stress- and Metabolic-related Neuropeptides in the Rat Hypothalamus during Morphine Dependence and Withdrawal [PDF]

open access: yes, 2013
Chronic morphine treatment and naloxone precipitated morphine withdrawal activates stress-related brain circuit and results in significant changes in food intake, body weight gain and energy metabolism.

Compact integral manifolds of differential systems [PDF]

open access: yesarXiv, 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]

open access: yesarXiv, 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.
