Carrier extraction circuit

Feedback loop extracts demodulated reference signals from IF input and feeds signal back to demodulator. Since reference signal is extracted directly from carrier, no separate reference need be transmitted. Circuit obtains coherent carrier from balanced or unbalanced four-phase signal of varying characteristics

Hole polaron formation and migration in olivine phosphate materials

By combining first principles calculations and experimental XPS measurements, we investigate the electronic structure of potential Li-ion battery cathode materials LiMPO4 (M=Mn,Fe,Co,Ni) to uncover the underlying mechanisms that determine small hole polaron formation and migration. We show that small hole polaron formation depends on features in the electronic structure near the valence-band maximum and that, calculationally, these features depend on the methodology chosen for dealing with the correlated nature of the transition-metal d-derived states in these systems. Comparison with experiment reveals that a hybrid functional approach is superior to GGA+U in correctly reproducing the XPS spectra. Using this approach we find that LiNiPO4 cannot support small hole polarons, but that the other three compounds can. The migration barrier is determined mainly by the strong or weak bonding nature of the states at the top of the valence band, resulting in a substantially higher barrier for LiMnPO4 than for LiCoPO4 or LiFePO4

AN ASSESSMENT OF THE IMPACT OF THE RURAL EMPOWERMENT ZONE AND ENTERPRISE COMMUNITY PROGRAM ON TEXAS' RIO GRANDE VALLEY

A Human Development Index (HDI) was developed to analyze the impact of the rural empowerment zone program on counties in the Texas Rio Grande Valley. Results of the analysis indicate that minimal development has taken place in these counties. This outcome is attributable to several institutional factors.Community/Rural/Urban Development,

Young women negotiating maternal subjectivities: the significance of social class

In this review article, we explore discursive configurations of motherhood and the ways in which class informs how young women engage with these in the construction of their biographies. Our theoretical starting point is principally sociological; we contend that the meanings and identities associated with 'the maternal' have been transformed by the impact of neo-liberalism, and that these produce dilemmas for young women as they constitute themselves as learners and future workers. This article reviews contemporary literature which engages with the ways in which the maternal is a key feature in the (re)making of classed and gendered identities
