Tension is a complex multidimensional concept that is not easily quantified. This research proposes three methods for quantifying aspects of tonal tension based on the spiral array, a model for tonality. The cloud diameter measures the dispersion of clusters of notes in tonal space; the cloud momentum measures the movement of pitch sets in the spiral array; finally, tensile strain measures the ...

Dynamo models for the structure of the regular magnetic field in the galaxy NGC 6946 are confronted with recent observations of polarized radio emission at λ3.5 cm. The observed behaviour of the concentration of regular fields between the gaseous spiral arms (“magnetic spiral arms”) is achieved via a non-axisymmetric azimuthal distribution of only the correlation time τcorr of interstellar turb...

Sliding clamps are toroidal proteins that encircle DNA and act as mobile platforms for DNA replication and repair machinery. To be loaded onto DNA, the eukaryotic sliding clamp Proliferating Cell Nuclear Antigen (PCNA) must be splayed open at one of the subunit-subunit interfaces by the ATP-dependent clamp loader, Replication Factor C, whose clamp-interacting sites form a right-handed spiral. E...

Data dissemination is a key problem that bottlenecks the wide application of wireless sensor network (WSN). In this paper, a novel data dissemination scheme−logarithmic spiral data dissemination (LSDD)−is proposed. In LSDD, data advertisements are disseminated following a spiral-like path, which involve only a small fraction of nodes in a sensor network. By exploiting nice features of spiral, t...

We submit a method for theMIREX 2008 task “Audio Chord Detection”. The method uses a 24-state HMM consisting of 12 states for both major and minor triads. The observation likelihoods are computed by mapping the pitch saliences into a pitch-class representation and comparing them with trained profiles for major and minor chords. Probabilities of between-chord transitions are estimated from train...

How microscopic chirality is reflected in macroscopic scale to form various chiral shapes, such as straight helicoids and spiral ribbons, and how the degree of macroscopic chirality can be controlled are a focus of studies on the shape formation of many biomaterials and supramolecular systems. This article investigates both experimentally and theoretically how the chiral arrangement of liquid c...

We examine models in which jets are responsible for the formation of the emission-line spiral structure in IRAS 04210+0400. The kiloparsec-scale radio lobes in this active galaxy appear to be related to its extended emission-line spiral structure. The radio structure consists mainly of extended symmetrically bent, FR I-type lobes, which follow the emission-line spiral structure at their inner e...

This article discusses a hot topic on double low-dose protocol of computed tomography pulmonary angiography (CTPA) in the diagnosis of pulmonary embolism, with a special focus on a recent paper published in the British Journal of Radiology about the feasibility of this technique. Three aspects will be discussed in this review: First, both kVp and contrast medium can be reduced without affecting...
