Abstract: A method for controlling a device for automatically adjusting an airway opening body position is provided. The device includes a horizontal base plate, a head support block, a back support plate, a neck support apparatus, a head cover assembly, and a programmable logic controller (PLC). The neck support apparatus is positioned between the head support block and the back support plate. The PLC is configured to controls a stroke of an electric cylinder according to the following equations: ?=1.235?+?, and ?=KX+B+C, where ? is a body position angle, the body position angle is an angle between a positive projection line of a connecting line from a mandibular angle to an external acoustic meatus on a symmetrical surface of a human body and the back support plate, and ? is a preset value ranging from 90° to 100°.

Abstract: Methods for modifying audio data include operations for accessing audio data having a first prosody, receiving a target prosody differing from the first prosody, and computing acoustic features representing samples. Computing respective acoustic features for a sample includes computing a pitch feature as a quantized pitch value of the sample by assigning a pitch value, of the target prosody or the audio data, to at least one of a set of pitch bins having equal widths in cents. Computing the respective acoustic features further includes computing a periodicity feature from the audio data. The respective acoustic features for the sample include the pitch feature, the periodicity feature, and other acoustic features. A neural vocoder is applied to the acoustic features to pitch-shift and time-stretch the audio data from the first prosody toward the target prosody.

Abstract: A preparation method of lipid bubbles by utilizing the principle of natural adsorption and assembly of amphiphilic lipid molecules on a gas-liquid interface comprises the steps of mixing gas-dissolved water containing free bubbles with lipid materials, and then the lipid materials are dispersed in the free gas nanobubble aqueous solution, and, in the presence of free bubbles, adsorbed and assembled on the gas-liquid interfaces so as to form lipid bubbles. The method is different from the traditional ultrasound cavitation, the mechanical force action, the novel ink jet printing method, the microchannel method and other methods for preparing bubbles.
