Abstract: A radio-frequency (RF) front-end circuit includes a tunable filter, a negative transconductance circuit coupled with the tunable filter to produce a tuning oscillation signal, and a counter arranged to determine a frequency of the tuning oscillation signal. The RF front-end circuit also includes a control circuit arranged to shift the frequency of the tuning oscillation signal by adjusting the tunable filter until the frequency of the tuning oscillation signal falls within an acceptable frequency range corresponding to a desired channel frequency band.

Abstract: A group of amino substituted benzoyl derivatives, their preparation and their use. The screening and research on an antiviral drug with hA3G/Vif as a target point proves that the 3-amino benzoyl derivatives not only have the combined activity for the hA3G/Vif, but also have a function of inhibiting replication of viruses. The present invention provides the possible breakthrough progress for the problem of HIV drug resistance, thereby providing a novel clinical antiviral drug which has higher efficiency.

Abstract: A system and method for simulating resource allocation, where the allocation strategies which can be simulated include those of prior art but also include a large class of important allocation strategies that are not possible or not easy to simulate using prior art techniques and systems is described. A location limiting allocation strategy is also described. This strategy supports resource capacity schedules and request priorities as supported by prior art, but simultaneously supports the enforcement of allocation limits applied to a property expressed in the allocation request, namely the location of the work to be performed, or a location, resource pair to perform the work.
