Recently, differential-signaling (DS) techniques such as low-voltage differential-signaling (LVDS) have been widely used in digital electronics devices in order to suppress electromagnetic interference (EMI). But in practical terms, a complete topologically and structurally symmetrical differential line is impossible. In this paper, we newly attempt to quantify the imbalance component and elect...

Five pyramidal cells from the posteromedial barrel subfield of mouse SmI cortex were labeled by Golgi impregnation and then gold-toned and de-impregnated (Fairen, Peters & Saldanha, 1977). Subsequently, 40 to 70 pm-long segments of their apical dendrites occurring in layer IV were graphically reconstructed from serial thin sections to determine the distribution of their synapses. Thalamocortica...

Supersaturated design (SSD) has received much interest because of its potential in factor screening experiments. Most studies focus on the construction and analysis of symmetrical SSDs. This paper considers the construction of asymmetrical (or mixed-level) SSDs. A new construction method, called the substitution method, for E(fNOD ) optimal and nearly-optimal SSDs is proposed. The basic idea of...

The nature of the intramolecular hydrogen bond in the enol tautomer of 2,4-pentanedione has been investigated by high resolution proton and deuteron magnetic resonance spectroscopy. An unusually large deuterium isotope effect on the chemical shift of the bridge hydrogen has been observed. This unexpected result, together with the observation of a pronounced temperature dependence for both the p...

Bilateral symmetry is visually salient to diverse animals including birds, but whereas experimental studies typically use bilaterally symmetrical two-dimensional patterns that are viewed approximately fronto-parallel; in nature, animals observe three-dimensional objects from all angles. Many animals and plant structures have a plane of bilateral symmetry. Here, we first (experiment I) give evid...

Responses of 99 cochlear nucleus cells and 24 cochlear nerve fibers were studied with FM signals; 14 cochlear nerve fibers and 57 cochlear nucleus cells were studied at four rates of modulation and several signal intensities. Classification of FM response patterns as symmetrical, asymmetrical, or unidirectional was based on the calculation of a symmetry factor (S), which compared the number of ...

We analyzed 12 combined mitochondrial and nuclear gene datasets in seven orders of insects using both equal weights parsimony (to evaluate phylogenetic utility) and Bayesian methods (to investigate substitution patterns). For the Bayesian analyses we used relatively complex models (e.g., general time reversible models with rate variation) that allowed us to quantitatively compare relative rates...

The present study applied network analysis to scrutinize spatial behavior of rats tested with symmetrical or asymmetrical layout of 4, 8, or 12 objects along the perimeter of a dark, round arena. We considered locations as the units of a network (nodes), and passes between locations as the connections of the network. In terms of Ethovision parameters, there were only minor differences between r...
