摘要:
Disclosed herein is a method of finding an isotopic cluster in a polypeptide and determining the monoisotopic mass of the cluster. The method comprises an algorithm for finding an isotopic cluster based on a probabilistic model, defined by each of peaks in the isotopic cluster, and determining the monoisotopic mass of the isotopic cluster. The probabilistic model of the isotopic cluster includes characteristic functions for mass, that is, a function of the ratio of two peak intensities, and a function of the product of two ratios obtained from three peaks. These characteristic functions for mass define the shape of peaks acceptable in an actual isotopic cluster for the mass of any isotopic cluster. The algorithm of finding the isotopic cluster based on the functions uses the characteristics to score the degree of the approximation of any isotopic cluster to the spectral shape of a theoretical cluster.

A semiconductor package and a package mounting substrate can be joined using a conductive material column. Each of the semiconductor package and the package mounting substrate include an insulating protective opening exposing a wiring layer therein. The solder column resides within the insulating protective openings to electrically couple the wiring layers.

A method of providing banking services by use of a mobile communication system having a removable built-in integrated circuit (IC) card chip in which personal identification number (PIN) information and related information on financial accounts of a user are stored. The method includes selecting an electronic bankbook service and selecting any one from financial transactions for the electronic bankbook service and comparing the PIN information input at the mobile communication system with the PIN information stored in the IC card chip, and authenticating access to data stored in the IC card chip on the mobile communication system. The method further includes displaying financial account information of the user stored in the IC card chip in a display window of the mobile communication system and forming a financial transaction request message using the related information of the selected financial account through a banking application built in the mobile communication system, and transmitting the financial transaction request message to the banking server. The method further includes performing a predetermined customer authentication process with respect to the financial transactions and financial accounts at the banking server, and transmitting a financial transaction response message to the mobile communication system and displaying the resulting transaction history in the display window of the mobile communication system.
摘要:
In one embodiment, a semiconductor package and a package mounting substrate are joined using a conductive material column such as a solder column. Each of the semiconductor package and the package mounting substrate include an insulating protective opening exposing a wiring layer therein. The solder column resides within the insulating protective openings to electrically couple the wiring layers. By forming the insulating protective openings with sufficient depth, each protects the solder column against stress faults and thereby forms more reliable electrical connections and supports high-density electrical connections between the semiconductor package and the package mounting substrate.
摘要:
The present invention provides a stacked chip package having at least one heat transfer wire. The heat transfer wire is disposed between the stacked chips and at least one end of each transfer wire is connected to a dummy pad provided on the board. Therefore, the heat generated by the chips and trapped between the chips can be effectively dissipated. The heat transfer wires can be formed on the uppermost chip of the stacked chips to enhance the heat dissipation. In addition, by controlling the number or the size of the heat transfer wire, the thermal characteristics of the stacked chip package can be modified.
