AND INTRODUCTION The amplitude of the surfa.ce EMG is frequently used as the control input to myoelectric prostheses, as a measure of muscular effort, and has also been investigated as an indicator of muscle force This paper will review the methods which are used to estimate the EMG amplitude from recordings of the EMG waveform. (Note that this review does not include the related area of EMG-to...

A new whitening cosmetic essence, 'Concentre anti-tache nuit'(CAN) (Parfums Christian Dior), which contained 3% magnesium 1-ascorbyl 2-phosphate, vitamin A, and an antisense compound(DNA Na), was evaluated against solar simulated radiation-induced delayed tanning(DT) in the unexposed upper arm skin of 12 healthy Japanese females, aged 20 to 55 years. Whitening effect was estimated by observatio...

The aim of this study was to analyze the efficacy of mouthwashes containing hydrogen peroxide compared with 10% carbamide peroxide (CP) gel. Fifty enamel-dentin samples were obtained from bovine incisors and then stained in a tea solution. The stained samples were randomly divided into five groups according to the whitening product applied (n = 10): AS: no whitening (negative control), with the...

Micro-deformation mechanisms involved in thermoforming of alumina trihydrate (ATH) reinforced poly(methyl methacrylate) (PMMA) was investigated in a new experimental method replicating industrial heavy-gage thermoforming procedure. Uniaxial tension tests under non-steady thermal conditions were carried out at different forming rates and forming temperatures. Stress–strain curves and load–displa...

OBJECTIVE The purpose of this in vitro study was to compare the efficacy of a bleaching toothpaste containing Blue Covarine vs. conventional tooth bleaching techniques using peroxides (both in-office and at-home). MATERIAL AND METHODS Samples were randomly distributed into five experimental groups (n=15): C - Control; BC - Bleaching toothpaste containing Blue Covarine; WBC - Bleaching toothpa...

Bone "stress-whitens," becoming visibly white during mechanical loading, immediately prior to failure. Stress-whitening is known to make materials tougher by dissipating mechanical energy. A greater understanding of stress-whitening, both an optical and mechanical phenomenon, may help explain age-related increases in fracture risk that occur without changes in bone mineralization. In this work,...

The grey clustering method is suitable for the comprehensive assessment of soil environmental quality. However, the zero-weight problem exists in the general grey clustering method. In order to solve the defect and apply the grey clustering method to soil environmental assessment, this study improved the general grey clustering method by replacing the linear whitening functions with the exponen...

A new approach to Semi-Blind Channel Estimation (SBCE) technique for Multiple Input Multiple Output (MIMO) wireless communication system is proposed. It combines the Least Square (LS) and Minimum Mean Square Error (MMSE) Training Based Channel Estimation (TBCE) scheme with whitening rotation based orthogonal pilot maximum likelihood (OPML) semi-blind channel estimation (SBCE) scheme. In the new...

Program Number: 6099 Presentation Time: 11:00 AM–11:15 AM Functional Consequences of Fixational Eye Movements in People with Macular Disease Susana T. Chung, Girish Kumar. Optometry, UC Berkeley, Berkeley, CA. Purpose: A recent theory posits that slow-drifts of fixational eye movements (FEMs) serve to reformat the visual input of natural images, so that the amplitude of the spatial frequencies ...
