Fractional and unquantized dc voltage generation in THz-driven semiconductor superlattices

We consider the spontaneous creation of a dc voltage across a strongly coupled semiconductor superlattice subjected to THz radiation. We show that the dc voltage may be approximately proportional either to an integer or to a half- integer multiple of the frequency of the applied ac field, depending on the ratio of the characteristic scattering rates of conducting electrons. For the case of an ac field frequency less than the characteristic scattering rates, we demonstrate the generation of an unquantized dc voltage.

The United Methodist Church at 40: What Can We Hope For?

The necessity we face for the future of Methodism is the re-invention of traditions. To re-invent traditions is to re-visit the past with all of its richness; to discern what in our tradition is most central to Christian faith; to analyze those parts of our past that continue to give life; to discern and build upon what is of value in the newly emerging tradition; and to reflect on those aspects of the neglected and rejected past that challenge our present perspectives and practices. To re-invent traditions is to develop new perspectives and practices from the building blocks of the past and from the fresh movements of the Spirit in the present. To do so is to recognize that Christianity in general, and Methodism in particular, is marked by traditions that have continually been passed on, critiqued, eliminated, created, and re-invented for the sake of a living Christian witness. What we can hope for is that God is there in the future already, pulling us toward God’s own New Creation.

Occupational lead neurotoxicity: A behavioural and electrophysiological evaluation. study design and year one results.

To evaluate the effects of chronic lead exposure on the nervous system in adults, a set of neurobehavioural and electrophysiological tests was administered to 99 lead exposed foundry employees and 61 unexposed workers. Current and past blood lead concentrations were used to estimate the degree of lead absorption; all previous blood lead concentrations had been less than or equal to 90 micrograms/100 ml. Characteristic signs (such as wrist extensor weakness) or symptoms (such as colic) of lead poisoning were not seen. Sensory conduction in the sural nerve was not affected. By contrast, various neurobehavioural functions deteriorated with increasing lead burden. Workers with blood lead concentrations between 40 and 60 micrograms/100 ml showed impaired performance on tests of verbal concept formation, visual/motor performance, memory, and mood. Thus impairment in central nervous system function in lead exposed adults occurred in the absence of peripheral nervous system derangement and increased in severity with increasing lead dose.
