Abstract: A heat and acid resistant probiotics microsphere having a size from 20 to 250 ?m that can readily be incorporated into food or beverages that subsequently undergo thermal treatment. The synbiotic core includes a seed layer formed from at least one polysaccharide. A probiotic microorganism is coated on the seed layer. An acid-resistant shell layer is positioned over the synbiotic core, the acid-resistant shell layer comprising one or more pH-responsive polymers. A heat-resistant bilayer shell is positioned over the acid-resistant shell layer, the heat-resistant bilayer shell including an inner shell layer and an outer shell layer, wherein the inner shell layer includes a heat-resistant liposome layer and the outer layer includes a heat-resistant disaccharide or polysaccharide.

Abstract: A low-dropout regulator with a single-transistor-control providing improved transient response and stability is disclosed. The single-transistor-control provides a dynamic resistance at the output of the regulator for minimizing undershoot and overshoot, and hence improves transient response. Since the single-control transistor reduces the output resistance of the regulator, the output pole is pushed to a sufficiently high frequency without affecting stability. Therefore, the limited choice of combinations of the output capacitance and its equivalent-series-resistance is substantially relaxed.
