We examined the effect of the human T lymphotropic virus type 1 (HTLVI) Tax gene product on the human transforming growth factor 01(TGF-01) promoter. Transfection of deleted constructs of the TGF-fl1 promoter revealed regions homologous with AP-1 binding sites that were required for Tax-induced transactivation of the TGF-(31 promoter. In addition, we(More)
This article has been accepted for publication in a future issue of this journal, but has not been fully edited. Content may change prior to final publication. Abstract—In this paper, the power allocation problem is solved in the context of maximizing the energy efficiency (EE) of orthogonal frequency division multiplexing (OFDM) signaling over a two-way(More)
—We consider digital predistortion (DPD) for linearizing power amplifiers (PAs) of hybrid MIMO systems with subarrays. Designing such a DPD scheme is difficult because one DPD should linearize all PAs of a subarray whose beamforming coefficients are time-varying. We develop an adaptive DPD technique for each subarray based on direct learning method(More)
A common sense of time among all the elements of a distributed measurement and control system allows the use of new techniques for the solution of problems with complex synchronization requirements or arising from the interaction of many sensors and actuators. Such a common sense of time may be accomplished using IEEE Standard for a Precision Clock(More)
—We consider bit allocation for channel state information (CSI) feedback in coordinated beamforming (CB) systems. The optimization problem under consideration is to minimize the total transmission power subject to the target signal to interference and noise ratio (SINR) constraints. We obtain a suboptimal solution to the problem that provides closed-form(More)
In recent, domestic livestock farms are receiving enormous damages through various livestock diseases that are highly contagious such as foot-and-mouth disease and avian influenza (AI). Additionally, they are experiencing difficulties also financially as a result of decrease in income from production cost increase. This paper will propose a livestock(More)
