Nanoelectromechanical Systems Face the Future Michael Roukes

Much to Feynman's consternation the young man who met this challenge, William McLellan, did so by investing many tedious and painstaking hours building the device by hand using tweezers and a microscope (figure 1). McLellan's motor now sits in a display case at the California Institute of Tech- nology and has long since ceased to spin. Meanwhile, in the field that Feynman hoped to incite, the wheels are turning- (a) Richard Feynman viewing the micromotor built by William McLellan (left) who won the challenge to both figuratively and literally — in many build the first motor smaller than l/64th of an inch, (b) The motor, 3.81 mm wide, photographed under f, university and corporate laboratories, an optical microscope.

The Role of Emotion in Musical Improvisation: an Analysis of Structural Features
The Role of Emotion in Musical Improvisation: An Analysis of Structural Features Malinda J. McPherson1*, Monica Lopez-Gonzalez1,2, Summer K. Rankin1, Charles J. Limb1,2 1 Department of Otolaryngology-Head and Neck Surgery, Johns Hopkins University School of Medicine, Baltimore, Maryland, United States of America, 2 Peabody Conservatory of The Johns Hopkins University, Baltimore, Maryland, United States of America Abstract One of the primary functions of music is to convey emotion, yet how music accomplishes this task remains unclear. For example, simple correlations between mode (major vs. minor) and emotion (happy vs. sad) do not adequately explain the enormous range, subtlety or complexity of musically induced emotions. In this study, we examined the structural features of unconstrained musical improvisations generated by jazz pianists in response to emotional cues. We hypothesized that musicians would not utilize any universal rules to convey emotions, but would instead combine heterogeneous musical elements together in order to depict positive and negative emotions. Our findings demonstrate a lack of simple correspondence between emotions and musical features of spontaneous musical improvisation. While improvisations in response to positive emotional cues were more likely to be in major keys, have faster tempos, faster key press velocities and more staccato notes when compared to negative improvisations, there was a wide distribution for each emotion with components that directly violated these primary associations. The finding that musicians often combine disparate features together in order to convey emotion during improvisation suggests that structural diversity may be an essential feature of the ability of music to express a wide range of emotion. -

We infer optical-absorption- induced heating and damping of the mechanical resonator from measurements of phonon occu- pancy and motional sideband asymmetry. At the lowest probe power and lowest fridge temperature (Tf = 10 mK), the localized mechanical resonance is found to couple at a rate of γi=2π = 400 Hz 6 (Qm = 9 × 10 ) to a thermal bath of temperature Tb ≈ 270 mK. These measurements indicate that silicon optomechanical crystals cooled to millikelvin temperatures should be suitable for a variety of experiments involving coherent coupling between photons and phonons at the single quanta level. acoustic 0.5 Introduction. - The coupling of a mechanical object's a b c − ωm ωm radiation κi 0.4 motion to the electromagnetic field of a high finesse cav- shield 0.3 R ity forms the basis of various precision measurements [1], 0.2 κ = κe+κi from large-scale gravitational wave detection [2] to mi- 0.1 0 croscale accelerometers [3]. -

A Computational Analysis of Uniqueness Points in Auditory Word Recognition
Perception & Psychophysws 1986, 39 (3), 155-158 A computational analysis of uniqueness points in auditory word recognition PAUL A. LUCE Indiana University, Bloomington, Indiana To determine the extent to which words in isolation may be recognized prior to their offsets, uniqueness points or optimal discrimination points were computed for all words in a 20,000oword computerized lexicon with more than two phonemes. The results of this analysis revealed that the frequency-weighted probability of a word’s diverging from all other words in the lexicon prior to the last phoneme was only .39. This finding suggests that an optimally efficient strategy of word recognition may be severely limited in scope due to structural properties of the mental lexicon. According to Marslen-Wilson’s (1984; Marslen-Wilson example, words of shorter length (e.g., car) may over- & Tyler, 1980; Marslen-Wilson & Welsh, 1978) cohort lap completely with the initial portions of words of longer theory of auditory word recognition, the initial acoustic- length (e.g., card or carbohydrate).
