We present the newest results for the determination of heavy-quark masses from low-energy moments of the vacuum polarization function. The results presented here update an earlier determination of the quark masses and incorporate new theoretical calculations of the low-energy moments of the vacuum polarization and new experimental data at the bottom threshold.

Rechargeable batteries are now widely used as the power supply source in many portable electronic equipments such as Laptops, cell phones and digital cameras. Charging circuits depend on the batterys chemistry and the most popular rechargeable batteries are Nickel-Cadmium (NiCd), Nickel-Metal-Hydride (NiMH), and Lithium-Ion (Li-Ion). This application report discusses the method to charge a Li-I...
