Acoustic topological adiabatic passage via a level crossing

Science China(Physics,Mechanics & Astronomy) 2021年第4期64卷 2-9页

Stimulated adiabatic passage has been extensively studied to achieve robust and selective population transfer in quantum systems. Recently, the quantum-classic analogy has been rapidly developing and can be considered responsible for the implementation of the adiabatic transfer of sound energy in cavity chain systems. In this article, we investigate the adiabatic transfer of sound energy between two topological end states in the Su-Schrieffer-Heeger(SSH) cavity chain, which can be considered to be the acoustic analog of the quantum chirped-pulse excitation. The topological adiabatic passage in SSH cavity chain has two categories. When the single-cavity resonance frequencies on the sublattices A and B in the SSH cavity chain do not switch their spectrum positions, the topologically protected adiabatic evolution results in the returning passage of the sound excited in one end cavity. When a level crossing with single-cavity resonance frequencies on the sublattices A and B exhibits switch in the frequency spectrum, acoustic energy is observed to be topologically pumped between the two end cavities of the SSH chain.

This work presents an adaptive tracking guidance method for robotic fishes. The scheme enables robots to suppress external interference and eliminate motion jitter. An adaptive integral surge line-of-sight guidance rule is designed to eliminate dynamics interference and sideslip issues. Limited-time yaw and surge speed observers are reported to fit disturbance variables in the model. The approximation values can compensate for the system's control input and improve the robots' tracking ***, this work develops a terminal sliding mode controller and third-order differential processor to determine the rotational torque and reduce the robots' run jitter. Then, Lyapunov's theory proves the uniform ultimate boundedness of the proposed method. Simulation and physical experiments confirm that the technology improves the tracking error convergence speed and stability of robotic fishes.

AIM:To describe the clinical characters of rhegmatogenous retinal detachment(RRD) associated with massive spontaneous suprachoroidal hemorrhage(SSCH). To evaluate optimal timing and prognosis of pars plana ***:A retrospective review of 6 cases(6 eyes)of RRD and massive SSCH among 3772 cases of RRD was conducted. All of 6 patients were treated with twenty-gauge vitrectomy, suprachoroidal blood drainage,phacoemulsification(PHACO) or lensectomy and silicon oil tamponade. The clinical characters, intraoperative findings and treatment outcomes were ***:In the 6 affected eyes of 6 patients(3 men and 3 women; mean age, 53.83y; range 34-61y),preoperative visual acuity ranged from faint light perception(LP) to counting finger(CF). The average interventional duration from visual decreased to surgery was 12.8 d(range 9-15d). All eyes were associated with high myopia and the mean ocular length was 30.32 mm(range 28.14-32.32 mm). Choroidal hemorrhage were successfully drained in the operation of all 6 *** findings showed there were multiple retinal breaks in all 6 eyes and in 4 eyes breaks were along supratemporal and/or infratemporal retinal vascular arcade, especially in the edge of chorioretinal atrophy areas. These patients were followed up from 6 to 34mo(Mean, 23.5mo). The best-corrected visual acuity after surgery varied from CF to 20/100, with improvement in 5eyes(83.33%) and no change in 1 eye(16.67%). Ocular hypertension ocurred in 1 eye(16.67%), which wassuccessfully treated by silicon oil removal combined with trabeculectomy. In 4 eyes, tractional retinal detachment caused by proliferative vitreoretinopathy(PVR) appeared and a secondary surgery of pre-retinal membrane peeling and silicon oil retained were performed. In 4eyes, silicon oil cannot be removed. The initial and final reattachment rates were 33.33% and 66.67%, ***:RRD associated with massive SSCH is an extremely rare event. The most common risk

Implementation procedure for the generalized moving Preisach model based on a first order reversal curve diagram

引用

Rare Metals 2009年第4期28卷 355-360页

作者： HAN Yong zhu jie State Key laboratory for Advanced Metals and Materials University of Science and Technology Beijing Beijing 100083 China

First order reversal curves （FORC） of nanocomposite Nd2Fe14B/Fe3B magnetic materials were measured to attain a FORC diagram, which characterizes reversible magnetization, irreversible magnetization, and magnetic interactions in a hysteresis system. Then, generalized mov- ing Preisach model （GMPM） was implemented based on the FORC diagram. Reversible and irreversible magnetizations shown in FORCs and a FORC diagram were used as an input of GMPM. Coupling interaction between reversible and irreversible magnetizations was added when calculating reversible magnetization. Meanwhile, irreversible magnetic moments＇ interaction was approximately represented by mean field interaction. The result shows that the simulated main curves mostly coincide with the experimental curves.

Multipurpose audio watermarking algorithm

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2008年第4期9卷 517-523页

作者： Ning CHEN jie zhu Department of Electronic Engineering Shanghai Jiao Tong University Shanghai 200240 China

To make audio watermarking accomplish both copyright protection and content authentication with localization, a novel multipurpose audio watermarking scheme is proposed in this paper. The zero-watermarking idea is introduced into the design of robust watermarking algorithm to ensure the transparency and to avoid the interference between the robust watermark and the semi-fragile watermark. The property of natural audio that the VQ indices of DWT-DCT coefficients among neighboring frames tend to be very similar is utilized to extract essential feature from the host audio, which is then used for watermark ex-traction. And, the chaotic mapping based semi-fragile watermark is embedded in the detail wavelet coefficients based on the instantaneous mixing model of the independent component analysis (ICA) system. Both the robust and semi-fragile watermarks can be extracted blindly and the semi-fragile watermarking algorithm can localize the tampering accurately. Simulation results demonstrate the effectiveness of our algorithm in terms of transparency, security, robustness and tampering localization ability.

Predicting the fault-proneness of class hierarchy in object-oriented software using a layered kernel

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2008年第10期9卷 1390-1397页

作者： Peng HUANG jie zhu Department of Electronic Engineering Shanghai Jiao Tong University Shanghai 200240 China

A novel kernel learning method for object-oriented （00） software fault prediction is proposed in this paper. With this method, each set of classes that has inheritance relation named class hierarchy, is treated as an elemental software model. A layered kernel is introduced to handle the tree data structure corresponding to the class hierarchy models. This method was vali- dated using both an artificial dataset and a case of industrial software from the optical communication field. Preliminary experi- ments showed that our approach is very effective in learning structured data and outperforms the traditional support vector learning methods in accurately and correctly predicting the fault-prone class hierarchy model in real-life OO software.
