    Abstract: A method and system for processing information in a social network system are disclosed. The method includes: in a network system, especially in a social network system, adding a piece of information having a new information structure to serve as a basic unit for expression intension of a user while enabling a user to be capable of continuously releasing a piece of information having a simple structure as a basic unit for expressing intensions. This information having the new structure describes relative locations of multiple basic units expressing meanings when being exhibited, and the meanings thereof are expressed by using a combination of the recited basic units in a manner of the multiple basic units. As such, information expression efficiency in the system is improved, and the information screening capability is enhanced, thereby naturally implementing structured reorganization of the information and significantly improving the information processing capability of the system.

    Abstract: The present invention provides a device for analyzing the composition of a heteropolymer comprising a carbon nanotube through which the heteropolymer is driven by electrophoresis. The carbon nanotube also serves as one electrode in a reading circuit. One end of the carbon nanotube is held in close proximity to a second electrode, and each end of the carbon nanotube is functionalized with flexibly-tethered chemical-recognition moieties, such that one will bind one site on the emerging polymer, and the second will bind another site in close proximity, generating an electrical signal between the two electrodes when the circuit is completed by the process of chemical recognition.

    Abstract: The improved DC-DC converter apparatus includes a primary side circuit and a secondary side circuit that is galvanically isolated from the primary. The primary side induces a voltage in the secondary side that provides an output voltage for driving POLs. A controller in the primary senses a reflected output voltage signal that is coupled from the secondary and is proportional to the secondary output voltage with respect to a voltage regulation point determined by either a voltage divider circuit or the zener voltage in the secondary. The voltage regulation point is established by wide-tolerance electrical components, such as a zener diode, a resistor, or a combination, connected in the coupling device circuit.
