... We address a question if globular clusters (GC) in a protogalaxy could for some time evolve chemically as isolated systems, enriching themselves with heavy elements produced in first supernova events that follow initial star formation. We determine both the critical mass of a protoglobular cluster that is needed to retain the ejecta of the very first supernova, and the critical energy (i.e., number of supernovae) that is needed to expel the residual gas from a cluster of a given mass. ...

... One of the widely used models of neural network is the multi-layered perceptron [6]. The model network has layers of input and output elements called neurons. ... An input vector is put on the input layer, passes through the hidden layers, and arrives at the output layer. The corresponding output vector is determined by calculation of the neuron activity level for each layer using already known values of neuron activity of the previous layers. ...
