Reminders of personal mortality may tune attention toward positive information. Insofar as attending to positive things in life helps individuals to cope with awareness of death, individuals with higher trait self-control may be particularly adept at positive tuning under mortality salience. To test this hypothesis, the current study had participants complete a measure of trait self-control, co...

We study propagation and switching of slow-light pulses in nonlinear couplers with phase-shifted Bragg gratings. We demonstrate that power-controlled nonlinear self-action of light can be used to compensate for dispersion-induced broadening of pulses through the formation of gap solitons, to control pulse switching in the coupler, and to tune the propagation velocity.

This paper presents a PID tuning technique with the aim to reduce the degradation of the performance for the optimal settings (servo or regulation), when the operating mode of the system is different from the select one for tuning. The above is achieved from the definition of the Performance Degradation concept, that is a way for measuring this kind of loss on both extreme situations of tuning....

We describe methods used to measure and control tunes in the Fermilab Main Injector (FMI). Emphasis is given to software implementation of the operator interface, to the front-end embedded computer system, and handling of hysteresis of main dipole and quadrupole magnets. Techniques are developed to permit control of tune of the Main Injector through several acceleration cycles: from 8.9 GeV/c t...

To automatically annotate songs with descriptive keywords, a variety of content-based auto-tagging strategies have been proposed in recent years. Different approaches may capture different aspects of a song’s musical content, such as timbre, temporal dynamics, rhythmic qualities, etc. As a result, some auto-taggers may be better suited to model the acoustic characteristics commonly associated w...
