A new technique of spectrum analysis for PIXE based on the linear associative neural network has been developed. The network has high capability in the association of almost all elements across the periodic table in samples, in the quantification with wide dynamic range of the concentrations, and in the analysis speed.

Theory And Experiment

This paper considers the design of a binary scalar quantizer of Laplacian source and its application in compressed neural networks. The quantizer performance is investigated in a wide dynamic range of data variances, and for that purpose, we derive novel closed-form expressions. Moreover, we propose two selection criteria for the variance range of interest. Binary quantizers are further implemented for compressing neural network weights and its performance is analysed for a simple classification task. Good matching between theory and experiment is observed and a great possibility for implementation is indicated.

Lumbar Spinal

The enigmatic sensation of tingle involves the activation of primary sensory neurons by hydroxy-α-sanshool, a tingly agent in Szechuan peppers, by inhibiting two-pore potassium channels. Central mechanisms mediating tingle sensation are unknown. We investigated whether a stable derivative of sanshool—isobutylalkenyl amide (IBA)—excites wide-dynamic range (WDR) spinal neurons that participate in transmission of chemesthetic information from the skin. In anesthetized rats, the majority of WDR and low-threshold units responded to intradermal injection of IBA in a dose-related manner over a >5-min time course and exhibited tachyphylaxis at higher concentrations (1 and 10%). Almost all WDR and low-threshold units additionally responded to the pungent agents mustard oil (allyl isothiocyanate) and/or capsaicin, prompting reclassification of the low-threshold cells as WDR. The results are discussed in terms of the functional role of WDR neurons in mediating tingle sensation.

Psychological Improvement

Triamcinolone was administered sublesionally to 48 patients with various dermatoses of the legs and feet. Results were satisfactory in 94 percent of those treated. Gratifying results were obtained in patients who had suffered from intractable psoriasis of many years' duration, great cosmetic and psychological improvement being noted in these individuals. Side effects consisted mainly of atrophy, which was of insignificant consequence in almost all instances. This administration, performed as directed, is recommended for a great number of skin disorders commonly encountered in podiatry.

Envelope Spectrum

Abstract In this paper, a new technique using optimum complex envelope spectrum is proposed in order to diagnose the gearbox fault, and its fundamental principle is described. The result of simulated tests illustrates that method proposed is excellently sensitive to the gearbox fault and is more effective than both the power spectrum analysis and the cepstrum analysis.
