    Abstract: A method and apparatus for real time speech recognition with and without speaker dependency which includes the following steps. Converting the speech signals into a series of primitive sound spectrum parameter frames; detecting the beginning and ending of speech according to the primitive sound spectrum parameter frame, to determine the sound spectrum parameter frame series; performing non-linear time domain normalization on the sound spectrum parameter frame series using sound stimuli, to obtain speech characteristic parameter frame series with predefined lengths on the time domain; performing amplitude quantization normalization on the speech characteristic parameter frames; comparing the speech characteristic parameter frame series with the reference samples, to determine the reference sample which most closely matches the speech characteristic parameter frame series; and determining the recognition result according to the most closely matched reference sample.

    Abstract: A polarization fringe scanning digital interferometer includes an encoder r performing a phase polarization encoding on the wavefront coming from the optical component under test as it passes through the encoder. The encoded wavefront then passes through an analyzer into a video camera to produce electrical signals representing the interference pattern. The encoder includes in sequence, a polarizer having an adjustable polarization axis, a polarization film providing a polarization pinhole through the film and a quarter wave plate that preferably is a Fresnel plate.

    Abstract: A transgenic rice plant containing in its genome a recombinant DNA construct that includes a first nucleic acid having a sequence of a first Golden 2-like transcription factor (GLK) gene operably linked to its natural promoter and 5′ untranslated region (5′UTR), and a second nucleic acid having a sequence of a second GLK gene operably linked to its natural promoter and 5′UTR, the second GLK gene being distinct from the first GLK gene. The first GLK gene and the second GLK gene are both from a C4 plant and the transgenic rice plant exhibits a 65-106% increase in shoot biomass and a 50-95% increase in grain yield, as compared to an untransformed wild-type rice plant. Also provided is a method for producing the transgenic rice plant and a recombinant DNA construct that can be used in the method.

    Abstract: A method and apparatus for surface plasmon resonance imaging are provided for imaging the surface plasmon resonance signals caused by the interaction of biomolecules. In particular, the method and apparatus can image the slightly spectral change in a surface plasmon resonance mode by comparing the light intensities of two bands in the frequency domain of the surface plasmon.

    Abstract: Disclosed is a multifunctional interfacial layer, which includes a conducting fiber network and a polymer-based conductive medium. The conducting fiber network layer can serves as a physical barrier to contain lithium dendrites and provide mechanical strength. The polymer-based conductive medium can facilitate smooth contact with electrodes. Under thermal treatment, an interface additive included in the polymer-based conductive medium can diffuse to the surface of the electrode, resulting in formation of an in-situ interfacial layer on the electrode. Accordingly, the multifunctional interfacial layer can resolve the problems of poor mechanical property and chemical instability at elevated potential and temperature associated with PEO-succinonitrile solid polymer electrolyte and prevent dendritic growth of lithium anode.
