In the framework of SU (3) symmetry, we present a general analysis of B meson decays into two lighter uncharmed mesons (both pairs of pseudoscalar mesons and pairs of vector and pseudoscalar mesons). From the analysis we find constraints on γ and discuss their validity. The most useful new constraint is obtained by considering the decay modes B 0 → Kπ and B + → π 0 π +. In decays into pairs of ...

We establish one-dimensional spectral, or “normal modes”, stability of ZND detonations in the small heat release limit and the related high overdrive limit with heat release and activation energy held fixed, verifying numerical observations of Erpenbeck in the 1960s. The key technical points are a strategic rescaling of parameters converting the infinite overdrive limit to a finite, regular per...

This paper introduces the synchrosqueezed wave packet transform as a method for analyzing twodimensional images. This transform is a combination of wave packet transforms of a certain geometric scaling, a reallocation technique for sharpening phase space representations, and clustering algorithms for modal decomposition. For a function that is a superposition of several wave-like components wit...

The perception of consonance/dissonance of musical harmonies is strongly correlated with their periodicity. This is shown in this article by consistently applying recent results from psychophysics and neuroacoustics, namely that the just noticeable difference between pitches for humans is about 1% for the musically important low frequency range and that periodicities of complex chords can be de...

The normal modes have been calculated for three kinds of low energy y-turn structures resulting from recent conformational energy calculations by Nkmethy. Frequencies have been computed for a y-turn, a mirror-related 7-turn, and an inverse y-turn of CH3-CO-(L-Ala),-NH-CH3, with n = 3 and n = 5 , and for certain l4 C and l5 N derivatives of the n = 3 molecule. Correlations are evident between am...

The internal seiche structure of a small, shallow lake (Frains Lake, Michigan) is shown to be dominated by the higher order vertical modes. The resonalit frequencies and the vertical velocity profiles of each mode were predicted from observed temperature profiles. The ohserved resonant frequencies and observed phase shifts in the velocity profiles of each mode corresponded closely to those pred...

High frequency force balance ~HFFB! measurements have recently been utilized to identify the distribution of spatiotemporally varying fluctuating wind loads on buildings. These developments, predicated on their ability to compute any response component of interest, based on actual building characteristics, attempt to offer a framework that eliminates the need for mode shape corrections generall...

The receiver hydrophone array is the signal front-end and plays an important role in matched field processing, which usually covers the whole water column from the sea surface to the bottom. Such a large aperture array is very difficult to realize. To solve this problem, an approach called matched field processing based on least squares with a small aperture hydrophone array is proposed, which ...
