摘要： One embodiment of the present invention provides a receiver for wireless communication. The receiver includes a demodulator and at least one filtering mechanism coupled to the demodulator, and an analog-to-digital converter (ADC) coupled to the filtering mechanism. The filtering mechanism can be configured to function as a low-pass filter (LPF) or a band-pass filter (BPF), thereby enabling the receiver to function as a direct-conversion receiver or a low-intermediate frequency (low-IF) receiver.

摘要： A transmitter includes a modulating and combining circuit to which signals are supplied and modulated into in-phase and quadrature-phase signals. The in-phase and quadrature-phase signals are combined in a closed-loop voltage summing circuit. The voltage summing circuit is an amplifier using capacitors as negative feedback elements. The negative feedback improves the linearity of the modulator. An LC tank circuit at the output of the voltage summing circuit bandpass filters the output before being applied to a power amplifier and eventually transmitted by an antenna. A multi-summing amplifier with different frequency tuning can be used for a multi-band transmitter design.

摘要： An internal auction system may allow a seller to enter a scheduled auction. The scheduled auction may be a simple scheduled auction and a conditional scheduled auction. The internal auction system may receive parameters for the scheduled auction, determine a scheduled auction as a function of the received parameters, create the scheduled auction, and publish the scheduled auction at a specified start time on a seller e-commerce site visible to a buyer. A simple scheduled auction may be associated with a start time and a duration. A conditional scheduled auction may be associated with a condition and an action to be executed when the condition evaluates to a specified value.

摘要： A new cytotoxic T lymphocyte (CTL) assay has been discovered using two cell lines that stably express either green fluorescent protein (GFP) or red fluorescent protein (DsRed), which are distinguishable by FACS, fluorescence microplate reader, or fluorescence microscopy. Using one cell line as a target (T) to present antigen and the other, at the same number, as an internal control (reference, R), a new CTL assay (named fluorolysometric (FL)-CTL assay) way developed based on cytolysis of these fluorescent protein-expressing targets detectable by FACS. This FL-CTL assay was further extended for use with a fluorescent microplate reader. This FL-CTL assay was reproducibly used to determine primary CTL activity at high sensitivity when compared to other conventional assays with in vivo activated T cells against different antigens. This new reliable, sensitive, convenient, and economical CTL assay has broad application potentials for experimental and clinical use in different antigen and effector-target systems.
