The high frequency CV curves of MOS capacitor have been studied. It is shown that semiclassical model is a good approximation to quantum model and approaches to classical model when the oxide layer is thick. This conclusion provides us an efficient （semiclassical） model including quantum mechanical effects to do parameter extraction for ultrathin oxide device. Here the effective extracting strategy is designed and numerical experiments demonstrate the validity of the strategy.

This work proposes a Deep neural network(DNN) based method for reconstructing speech magnitude spectrum from Mel-frequency cepstral coefficients(MFCCs). We train a DNN using MFCC vectors as input and the corresponding speech magnitude spectrum as desired output. Exploiting the strong inference power of DNN, the proposed method has the capability to accurately estimate the speech magnitude spectrum even from truncated MFCC vectors. Experiments on TIMIT corpus demonstrate that the proposed method achieves significantly better performance compared with traditional methods.

This paper proposes the Decision feedbackfeedforward per-survivor processing(DFF-PSP) iterative separation algorithm and the Monte Carlo integrationbased method to compute the theoretical bound for Paired carrier multiple access(PCMA) Single channel blind separation(SCBS) which is highly complex with long memory. The truncated PSP is employed while the pre- and post- cursors are disregarded to control the *** delayed decisions feedforward and local decisions feedback filters are designed to process the pre- and postcursors. The Bit-interleaved code modulation iterative decoder(BICM-ID) is combined with the second soft decision of the truncated PSP to obtain a better *** mixture signal model is regarded as a Multiple-access channel(MAC) with memory, and the theoretical performance bound is obtained via entropy inequality, Monte Carlo integration and Fano inequality. Simulation results show that the DFF-PSP iterative separation provides the good tradeoff between complexity and performance.

As relaxor ferroelectric functional materials, their crystal structures depend on temperature, component, electric filed, pressure, and so on, which are important for the applications of sensors, transducers, and actuators. For the case of PbTiO3-based ferroelectrics Pb（Zn2/3Nb2/3）O3-PbTiO3, Pb（Mg1/3Nb2/3）O3-PbTiO3, Pb（In1/2Nb1/2）O3-Pb（Mgu3Nb2/3）O3-PbTiO3 and some other crystals, they have been extensively investigated due to the excellent electromechanical and piezoelectric properties. Generally, ferroelectric crystal structure and corresponding phase diagram are detected by temperature-dependent high resolution X-ray diffraction, low frequency dielectric permittivity, and domain structures. In this review, we focus on the novel condensed matter spectroscopy （i.e., spectroscopic ellipsometry, transmittance, photoluminescence spectra as well as Raman spectra）, which is nondestructive, noncontact, and sensitive optical techniques for probing symmetries, phase transitions and phase diagrams of ferroelectric crystals. Besides, it can supply some other physical and chemical information for ferroelectric and semiconductor functional materials such as optical band gap, electronic transitions, dielectric functions, optical conductivity, absorption, pho- non modes, lattice dynamics as functions of temperature and PT composition.

There is no experiencing without an experiencer, the self. Whether the experiencer knows it is ＂the self＂ that is experiencing is a different and tricky philosophical issue. Dating back to Ivan Pavlov＇s dogs, the ＂experience＂ of animals has been the subject of scientific research for over a century, yet to which extent different animals possess the sense of self is still hotly debated today. From human＇s perspective, the sense of self is the corner stone of feelings, thoughts, and social interactions--a necessity of higher intelligence.
