    Abstract: Disclosed is a method for processing FM-AM mixed halftone images on a multi-bit depth imaging apparatus, which relates to a method for producing halftone dots in the field of image hard copying. In the prior art, since it is hard to avoid the impact of the error diffusion for the output apparatus to control the mixed dots with multi-bit imaging depth based on the error diffusion, the output of the mixed dots with multi-bit imaging depth cannot satisfy requirements of the apparatus. According to the method of the present invention, the dynamic algorithm for controlling the multi-bit mixed dots is used for screening based on the existing mixed screening process using dual-feedback error diffusion. Furthermore, multi-bit halftone images with high quality and rich gradations can be output by the multi-bit depth imaging apparatus. The method of the present invention can solve the phenomenon of sawtooth in the margins of the mixed dots output by the conventional single-bit apparatus and obtain the FM-AM mixed dots with the effect of high resolution and continuous gradations, which are output under low resolution.

    Abstract: One approach to treating individuals infected with HIV-1 is to administer to such individuals compounds that directly interfere with and intervene in the machinery by which HIV-1 replicates itself within human cells. Although the specific role of HIV-1 viral protein Vif in the viral life cycle is not known, the vif gene is essential for the pathogenic replication of lentiviruses in vivo. The present invention relates to a method for treating an individual exposed to or infected with HIV-1. Individuals identified as being exposed to or infected by HIV-1 are administered a therapeutically effective amount of one or more compounds that inhibit or prevent replication of said HIV-1 by interfering with the replicative or other essential functions of HIV-1 viral protein Vif by interactively blocking the multimerization domain of Vif, thereby preventing multimerization of Vif protein, which is important for Vif function in the lentivirus life cycle. In preferred embodiments, the compound or compounds that interactively block the multimerization domain of Vif are Vif antagonists. Pharmaceutical compositions comprising these compounds are also disclosed.

    Abstract: A field effect transistor configured for use in high power applications and a method for its fabrication is disclosed. The field effect transistor is formed of III-V materials and is configured to have a breakdown voltage that is advantageous for high power applications. The field effect transistor is so configured by determining the operating voltage and the desired breakdown voltage for that operating voltage. A peak electric field is then identified that is associated with the operating voltage and desired breakdown voltage. The device is then configured to exhibit the identified peak electric field at that operating voltage. The device is so configured by selecting device features that control the electrical potential in the device drift region is achieved. These features include the use of an overlapping gate or field plate in conjunction with a barrier layer overlying the device channel, or a p-type pocket formed in a region of single-crystal III-V material formed under the device channel. The overlapping gate/field plate or p-type pocket extend into the drift region of the device, controlling the electrical potential of the device in a manner that provides the desired control of the electrical potential in the drift region.

    Abstract: A signal strength compensation unit for mobile radio receivers is connected upstream of the channel estimator and the channel equalizer and compensates for, in particular, the great, brief signal strength fluctuations within a data burst. Likewise, a method for signal strength compensation compensates for brief signal strength fluctuations within the data burst. To these ends, a signal strength average is determined from the signal strengths for the previously received data symbols. The current signal is then aligned with this signal strength average. The inventive signal strength compensation allows the bit error rate during data equalization to be significantly reduced.

    Abstract: A Viterbi equalizer for equalization of a data signal transmitted via a channel that is subject to interference has at least one add-compare-select unit (ACS), which carries out an ACS operation for each channel state in a time step k. Furthermore, the equalizer has a unit for calculating metric increments in advance and for storing the metric increments. The calculation unit calculates in advance the metric increments relating to all the transitions from a state which can be predetermined in the time step k to the states which can be reached by the transitions in the time step k+1. The metric increments are retained in an output memory such that they can be called up for utilization in the ACS unit.
