Two phenotypes are present within the European eel population: broad-heads and narrow-heads. The expression of these phenotypes has been linked to several factors, such as diet and differential growth. The exact factors causing this dimorphism, however, are still unknown. In this study, we performed a feeding experiment on glass eels from the moment they start to feed. Eels were either fed a ha...
Received Jul 15, 2016 Revised Mar 13, 2017 Accepted Mar 27, 2017 Interline Dynamic Voltage Restorer (IDVR) comprises of several Dynamic Voltage Restorers (DVRs) connected to different distribution feeders in the power system sharing common energy storage. One of the DVR provides for voltage sag compensation appearing in that feeder, while the other DVRs restore the energy in the common dc-link ...
A Machine Learning (ML) System known as ROAMS (Ranker for Open-Auto Maintenance Scheduling) was developed to create failure-susceptibility rankings for almost one thousand 13.8kV-27kV energy distribution feeder cables that supply electricity to the boroughs of New York City. In Manhattan, rankings are updated every 20 minutes and displayed on distribution system operators’ screens. Additionally...
Urban environments cover vast areas with a high density of humans and their dogs and cats causing problems for exploitation of new resources by wild animals. Such resources facilitate colonization by individuals with a high level of neophilia predicting that urban animals should show more neophilia than rural conspecifics. We provided bird-feeders across urban environments in 14 Polish cities a...
Flexible parts feeding techniques have recently begun to gain industry acceptance. However, one barrier to effective flexible feeding solutions is a lack of knowledge of the underlying dynamics at work in flexible part feeders. This paper begins to address this topic. First, we discuss statistical modeling of the feeders’ sub-systems and the fed parts themselves. For each feeding situation, we ...
Memory systems have evolved under selection pressures, such as the need to remember the locations of resources or past events within spatiotemporally dynamic natural environments. The full repertoire of complex behaviours exhibited by animals in dynamic surroundings are, however, difficult to elicit within simply structured laboratory environments. We have developed a computer-controlled natura...
Observations were made on the animal's behavior and dynamics of electrical activity in the neo- and archipaleocortex during acquisition of sound discrimination under different experimental conditions and subsequent extinction. On the basis of analysis of the data obtained the following conclusions were drawn: (1) In pre-satiated cats even hundreds of applications of conditioned stimuli without ...
Because cell culture systems are easily accessible for experimental genetic manipulation, male germ cell culture is of great usefulness in creating sperm vectors. This report describes that cultured male germ cells of zebrafish (Danio rerio) underwent mitosis and transmeiotic differentiation, including the entire process of meiosis, to develop into functional sperm. Enzymatically dissociated te...
