Abstract: A method of designing a neural network system includes the following steps. Firstly, a neural network system is defined. The neural network system includes an original weight group containing plural neuron connection weights. Then, a training phase is performed to acquire values of the plural neuron connection weights in the original weight group. Then, the plural neuron connection weights into first-portion neuron connection weights and second-portion neuron connection weights according to a threshold value, wherein absolute values of the first-portion neuron connection weights are lower than the threshold value. Then, the values of the first-portion neuron connection weights are modified to zero. Then, a modified weight group is generated. The zero-modified first-portion neuron connection weights and the second-portion neuron connection weights are combined as the modified weight group.

Abstract: The disclosure provides a culturing medium for culturing a bacterium of genus Tepidimonas, including: a carbon source which is an organic acid, selected from a group consisting of acetate, lactate and butyrate; a nitrogen source selected from a group consisting of ammonium sulfate ((NH4)2SO4), ammonium nitrate (NH4NO3), ammonium chloride (NH4Cl) and urea; phosphate; magnesium chloride (MgCl2); yeast extract; and trace elements.

Abstract: A method for recycling metals is provided by using extracellular proteins excreted by a specific thermophilic bacteria strain, Tepidimonas fonticaldi sp. nov., in which the extracellular proteins show excellent metal-ion binding ability, being useful in recycling rare earth metal ions and precious metal ions from geothermal fluids, boiler solutions, industrial wastewater or hard water.
