A liquid crystal display including a first substrate, a second substrate, a plurality of sensors, and a position detection device is disclosed. A first component of the actuator may have two openings interconnected by a passageway. The CTE contains a rules database. Also provided are vectors comprising such nucleotide sequences, including bacterial, insect, and mammalian expression vectors, which nucleotide sequences are operatively associated with an expression control sequence. A signal inputoutput end of the antenna is at another end of the balun transformer. The cathode catalyst has a high activity and selectivity for a reduction reaction of an oxidant, and is highly stable under an acidic atmosphere thereby being capable of improving performances of a membrane-electrode assembly and fuel cell system.
