Abstract: Dentifrice compositions comprising water, bicarbonate salt, and glycine or a salt thereof are effective in treating dental plaque biofilm. A dentifrice composition may include from about 15% to about 55%, by weight of the composition, of water, from about 20% to about 40% by weight of the composition, of sodium bicarbonate, from about 0.05% to about 5%, by weight of the composition, of neutral amino acid, where the neutral amino acid comprises glycine or a salt thereof, and from about 0.0025% to about 2%, by weight of the composition, of fluoride.

Abstract: Terahertz spectrum measurement method and system based on an unequal optical path method is provided. By using a Femtosecond laser and a Terahertz time-domain spectroscopy system, samples to be measured and having different thicknesses are subjected to scanning by time-domain Terahertz signals to obtain transmission signals of the samples with two different thicknesses. The signal after passing through a sample with the thickness of d1 is a reference signal, and the signal after passing through a sample with the thickness of d2 is a sample signal. When Terahertz waves are normally incident to the samples and having different thicknesses, the signals emitted from the samples have an optical path difference therebetween. Phase-containing frequency spectra are obtained after time-domain signals are subjected to Fourier transform. The parameters, such as a refractive index, an extinction coefficient, and an absorption coefficient, can be calculated through the extracted phase-containing frequency spectrums.

Abstract: The disclosure relates to an information processing apparatus and information processing method. The information processing apparatus according to an embodiment includes a processing circuitry configured to: derive a disparity map of an object based on at least two images among multi-view images of the object; estimate confidences of disparity values in the disparity map using a classifier trained in advance; and perform an optimization process on the disparity map based on disparity values of reference pixels having confidences higher than a predetermined level.
