Abstract

A glass ceramic is provided to address the challenge that bioceramics known to be used for bone defect repair often lack good hardness, proper degradability, low post-implantation stimulation to surrounding tissues and promotion of bone defect repair in combination. The glass ceramic comprises a major crystallized phase, which is either diopside or wollastonite; and a minor crystallized phase, which comprises any one or more selected from the group consisting of diopside, wollastonite, lithium disilicate, silicon dioxide, lithium metasilicate and Li2Ca2Si5O13. In the glass ceramic, the molar ratio of elemental calcium, elemental lithium and elemental silicon is 1:x:2, in which x is from 0.05 to 1. However, when the major crystallized phase is diopside, the minor crystallized phase does not comprise diopside; and when the major crystallized phase is wollastonite, the minor crystallized phase does not comprise wollastonite. The present invention also comprises a method for manufacturing the glass ceramic.

The present invention provides a method of sugar-guided modifying a glycosylated polypeptide. First, a boronic acid group of a probe molecule and a sugar group of the glycosylated polypeptide form a first covalent bond. Next, an alkyne group of a modifying group and an azide group of the probe molecule form a second covalent bond by adding a promoter. As a result, the modifying group can be close to the glycosylated polypeptide. Then, the modifying group can bind to a nucleophilic residue that is near the sugar group, through a nucleophilic addition reaction. The method of the present invention can selectively modify a given site with the guidance of the sugar group.

Abstract

A one-way glass with switching modes includes an absorbing layer located on a weak light side, a reflecting layer located on an intense light side, and a converting layer stacked between the absorbing layer and the reflecting layer. The absorbing layer absorbs first polarized light and allows second polarized light to pass through. The reflecting layer reflects the first polarized light and allows the second polarized light to pass through. Unpolarized light incident from the weak light side or from the intense light side is respectively converted into the polarized light. During the process of gradually adjusting the converting layer from a twisted state to a vertical state, rotated angles of polarization directions of the first polarized light and the second polarized light gradually decrease.

The SIL oscillator generates an electrical oscillation signal and receives an electrical injection signal related to the electrical oscillation signal for self-injection locking. The phase-tracking SIL loop receives the electrical oscillation signal and outputs the electrical injection signal to the SIL oscillator with a constant phase difference between the electrical oscillation signal and the electrical injection signal. The frequency-locked loop receives the electrical oscillation signal and produces an electrical control signal to control the phase-tracking SIL loop or the SIL oscillator for eliminating the frequency shift of the SIL oscillator caused by the phase-tracking SIL loop. Accordingly, the phase difference between the electrical oscillation signal and the electrical injection signal is maintained at 0° or 180° such that the phase-tracking SIL radar operates at optimal detection points.

Abstract

A multiple-target vital sign detector includes a self-injection-locked oscillator (SILO), a chirp up/down converter, a frequency demodulator and a multiple-target vital sign processor. The chirp up/down converter performs conversion from an oscillation signal generated by the SILO to a frequency-modulated continuous wave (FMCW) signal to detect an area and from a received FMCW signal reflected from the area to an injection signal, while the SILO is injected with the injection signal to enter a self-injection-locked state. The locations and vital signs of multiple subjects are extracted from the oscillation signal using the frequency demodulator and the multiple-target vital sign processor. The objective of using the SILO is to improve the sensitivity of the FMCW detection process so as to more effectively distinguish the vital signs of multiple subjects at different locations.

A reaction method with a homogeneous-phase supercritical fluid includes introducing a first fluid into a mixing chamber. A mass is less than or equal to that can be absorbed by the molecular sieve component, totally absorbing the first fluid by the molecular sieve component. A second fluid is introduced into the mixing chamber with a mass being greater than that can be absorbed by the molecular sieve component. A temperature and a pressure in the mixing chamber are adjusted to a critical temperature and a critical pressure of the second fluid, respectively, releasing the first fluid in supercritical phase from the molecular sieve component into the mixing chamber, followed by homogeneously mixing with the second fluid in supercritical phase in the mixing chamber to obtain a homogeneous-phase mixing fluid. The homogeneous-phase mixing fluid is then introduced into a reaction chamber connected to the mixing chamber.

Abstract

A method and apparatus for signal processing by light waveform shaping are provided to process an uplink signal generated by a digital-to-analog converter (DAC) and/or process a downlink signal to be transmitted to an analog-to-digital converter (ADC). The method includes adjusting the waveform of the uplink signal and/or the waveform of the downlink signal with a light waveform shaping module so that, even if the DAC and/or ADC has a low sampling rate and a narrow bandwidth, a high-frequency signal portion of the uplink signal and/or a high-frequency signal portion of the downlink signal can be preserved.

Abstract

A quadrature self-injection-locked radar utilizes a phase shifter to make a oscillation signal operating in two phase modes, and utilizes a frequency demodulator for frequency demodulation and a signal processor for signal processing to eliminate the nonlinear distortion caused by self-injection locked phenomenon. Therefore, the self-injection locked radar can be applied to more cases for detecting displacement variations with any range.

Abstract

A method for processing a biomedical material using a supercritical fluid includes introducing the supercritical fluid into a cavity. The supercritical fluid is doped with a hydrogen isotope-labeled compound, an organic metal compound, an element selecting from a halogen element, oxygen, sulfur, selenium, phosphorus or arsenic, or a compound containing the element. The biomedical material in the cavity is modified by the supercritical fluid at a temperature above a critical temperature of the supercritical fluid and a pressure above a critical pressure of the supercritical fluid.

Abstract

A non-contact vital sign monitoring system transmits wireless signals to the same side of a biological subject via two antennas with different gains, and the two antennas receive two reflected signals from the biological subject with random body movement. Under a proper setup of the two antennas, the two reflected signals can be adjusted by an amplitude and phase adjusting unit to have the Doppler shift components caused by body movement with equal magnitude and out of phase and the Doppler shift components caused by vital signs with different magnitude. Therefore, the random body movement effect can be cancelled based on the relation between the two reflected signals in using the system to monitor the vital signs of the subject.
