Abstract: The transition time of power switching devices ultimately limits the rate at which such devices can be switched. Because the occurrence of unacceptably narrow pulses is relatively rare in an oversampled, noise-shaping signal processor, the elimination of such narrow pulses is introduced through the use of circuitry in the modulator loop which constrains the time between transitions to be greater than or equal to some minimum time period which, in turn provides for a smooth interface to power switching devices. However, because of the delay introduced by this pulse qualification circuitry, the modulator loop sampling frequency is increased to deal with any resulting instability. Thus, an oversampled, noise shaping signal processor is described having at least one integrator stage in a feedback loop. A sampling stage in the feedback loop is coupled to the at least one integrator stage. The sampling stage samples an analog signal at a sample frequency. Qualification logic coupled to the sampling stage receives a pulse waveform therefrom, and ensures that signal transitions in the pulse waveform occur more than a first time period apart and that the waveform can therefore be handled by, for example, a power switching device. A switching stage in the feedback loop is coupled to the qualification logic. The signal processor has a feedback path from the output of the switching stage to the input of the at least one integrator stage thereby closing the feedback loop.

Abstract: The present invention provides a dual selection cassette (DSC) comprising first and second DNA segments having homology to a eukaryotic viral vector, positive and negative selection genes, each operably linked to their own promoter, and one or more unique restriction enzyme sites (URES) or sitey-directed homologous recombination sites. The present invention also provides a plasmid, pN/P, comprising an independent positive selection marker gene, an origin of replication, and a dual selection cassette. The dual selection cassette and pN/P plasmid can be used to produce eukaryotic gene transfer vectors without requiring temporally-linked double recombination events or the use of specialized bacterial strains that allow the replication of plasmids comprising defective origins of replication. This method usefully increases the ratio of desired to undesired plasmid and vector constructs. Additionally, this invention provides a method for the creation of eukaryotic viral vector libraries.

Abstract: E descritto un materiale in lega di alluminio per tissofusione. In una termografia di analisi termica differenziale per questo materiale in lega di alluminio per tissofusione è stabilita la correlazione E1? E2 tra un valore di picco E1 di una prima sezione endotermica di angolo generata dalla fusione di un eutettico ed un valore di picco E2 di una seconda sezione endotermica di angolo generata dalla fusione di un segmento avente un punto di fusione superiore al punto eutettico. Quindi una fase liquida prodotta dalla fusione dell'eutettico ha un grande calore latente perchè il valore di picco E1 della prima sezione endotermica di angolo è superiore al valore di picco E2 della seconda sezione endotermica di angolo in un materiale in lega di alluminio eutettico semifuso derivato dal materiale in lega di alluminio per tissofusione. Come risultato in una fase di solidificazione del procedimento per tissofusione una fase liquida prodotta dalla fusione di un eutettico è alimentata a sufficienza attorno ad una fase solida in risposta alla solidificazione ed al ritiro della fase solida e quindi solidificata. Perciò è possibile produrre una fusione priva di difetti come vuoti di ordine dal micron.
