PURPOSE Pikachurin is an extracellular matrix-like protein located in the synaptic cleft of photoreceptors. Pikachurin null mutant (Pika-/-) mice have abnormal ON bipolar cell function. This study aimed to determine the contribution of the ON bipolar cell pathway (ON pathway) of Pika-/- mice to the flicker ERG response and, using vector analysis, identify how the contribution varies with the st...

High levels of theory have been used to compute quartic force fields (QFFs) for the cyclic and linear forms of the C(3)H(3)(+) molecular cation, referred to as c-C(3)H(3)(+) and l-C(3)H(3)(+). Specifically, the singles and doubles coupled-cluster method that includes a perturbational estimate of connected triple excitations, CCSD(T), has been used in conjunction with extrapolation to the one-pa...

The effect of staging (n≤ 3) on the two-dimensional (2D) Fermi surface of PdAl 2 Cl 8 acceptor-type graphite intercalation compounds (GICs) has been investigated by the Shubnikov-de Haas effect. For the stage 1 and stage 2 compounds, one and two fundamental frequencies are observed, respectively. The measured angular variation of the fundamental frequencies confirms the 2D nature of the stage 1...

a r t i c l e i n f o a b s t r a c t Automatic transcription of polyphonic music is an important task in audio signal processing, which involves identifying the fundamental frequencies (pitches) of several notes played at a time. Its difficulty stems from the fact that harmonics of different notes tend to overlap, especially in western music. This causes a problem in assigning the harmonics to...

In this paper, a new stereoendoscopic high-speed digital imaging system and a method to estimate the glottal functions are proposed. Glottal length, width, and area of one male and one female participants were estimated in different fundamental frequencies.

Although laughter is an important aspect of nonverbal vocalization, its acoustic properties are still not fully understood. Extreme articulation during laughter production, such as wide jaw opening, suggests that laughter can have very high first formant (F(1)) frequencies. We measured fundamental frequency and formant frequencies of the vowels produced in the vocalic segments of laughter. Voca...

In this paper, a novel stereo-endoscopic high-speed digital imaging system and a method to estimate the glottal area function are proposed. Glottal length, width, and area of one female participant were estimated in three different fundamental frequencies (F0s).

We characterize quantum limits and semi-classical measures corresponding to sequences of eigenfunctions for systems coupled harmonic oscillators with arbitrary frequencies. The structure the set turns out depend strongly on arithmetic relations between frequencies each decoupled oscillator. In particular, we show that as soon these are not rational multiples a fixed fundamental frequency, is co...
