In this paper, we present a novel feature extraction framework, called learning by propagability. The whole learning process is driven by the philosophy that the data labels and optimal feature representation can constitute a harmonic system, namely, the data labels are invariant with respect to the propagation on the similarity-graph constructed by ...

Alterations in microscopic conduction could contribute to microreentry and arrhythmogenesis in pathological settings. This chapter reviews microconduction in the ventricular myocardium. Gap junctions play a significant role in longitudinal and transverse propagation of the action potential wavefront in the ventricle.

Back propagation and forward propagation
[Proceedings 1992] IJCNN International Joint Conference on Neural Networks, 2003The authors analyze the validity of the pessimistic views of M.L. Minsky and S.A. Papert (Perceptrons: An Intro. to Comput. Geom., MIT Press, Cambridge, MA, 1969) on the possibility of training multi-layer perceptrons. In particular, they show that it was possible, using the simplex algorithm of J.A. Nelder and R. Mead (Comput. Journ., vol.8, pp.308-13,

The policy of the Protein Data Bank (PDB) that the first deposition of a small-molecule ligand, even with erroneous atom numbering, sets a precedent over accepted nomenclature rules is disputed. Recommendations regarding ligand molecules in the PDB are suggested.

Abstract Visual spatio-temporal inhibition effects were investigated with the aid of “jumping flashes” (pairs of point flashes, separated in time and space). Plots of the visibility of the jumping flashes against the interval time, produced visibility curves in which two dips (representing inhibition effects) were observed.

Abstract This chapter discusses various peach propagation techniques, covering the following aspects: nursery seedling propagation (nursery site and soil, and propagation from seed); nursery hardwood cutting; greenhouse semi-hardwood cutting; micropropagation (preparation of the propagation material, explant disinfection and setting-up aseptic ...

Sunflower (Helianthus annuus L.) has been cultivated both as an oilseed and as an ornamental plant. Several protocols have been described for the micropropagation, direct plant regeneration by organogenesis being acceptable for this plant species. Besides a strong genotype dependency, the type and ontogenic stage of explants, environmental conditions ...

Propagation of roses by stem cuttings is one of the simplest and most used methods to propagate this ornamental species. Indeed, most of old roses, English roses, miniatures and some rootstocks are commonly propagated by cuttings because they can root easily and, further, grow vigorously on their own roots.

Wave phenomena are used to evaluate material properties nondestructively as well as to locate and measure defects in critical structures. In fact, physical acoustics is directly related to ultrasound since the ultrasonic waves are employed to determine the properties of materials.
