An interim power source includes an energy storage, a switch coupled with the energy storage, and a control circuit coupled with the switch. In an embodiment, a method of accessing information in a distributed database system having one or more data servers includes establishing a plurality of lattice structures configured to store data elements having inter-related information. The container, which is formed of a polyolefin-based sheet, comprises a container body and a cover and is provided with a pressure-releasing part whose adhesion strength is weak enough so that it can be opened by the vapor pressure that is generated inside the container when it is heated. The battery exhibits an exceptionally high specific capacity, an excellent reversible capacity, and a long cycle life. 100, where \u03b8gF1 denotes a partial dispersion ratio of a material of the positive lens, and vd1 denotes Abbe number of the positive lens. Further, the UE ignores the NDI with the first value received through the first downlink control channel identified by the temporary cell identifier.
