A high-silica content zeolite having a novel crystal structure, a zeolite membrane and manufacturing methods for these are provided, and the present invention relates to a zeolite having the chemical composition represented by. According to an embodiment, a DAC includes a plurality of sub-DACs, a DAC input adapted to receive a multi-bit digital input and a DAC output adapted to output an analog output current in response to and indicative of the digital input. The cross section of the body has, on the force output side, at least two contact sites via which the input force can be output in a distributed manner. In the servo pattern, four lines of preamble portions extending almost in a radial direction are formed and a plurality of pit portions disposed in a dotted manner in two lines are arranged. These proteins can be used for detecting the antifungal activity of molecules. Methods and systems are also provided.
