| 2 | Two-acceleration-error-input proportional-integral-derivative control for vehicle active suspension显示文摘The objective of this work is to present a new two-acceleration-error-input(TAEI) proportional-integral-derivative(PID) control strategy for active suspension.The novel strategy lies in the use of sprang mass acceleration and unsprung mass acceleration signals simultaneously,which are easily measured and obtained in engineering practice.Using a quarter-car model as an example,a TAEI PID controller for active suspension is established and its control parameters are optimized based on the genetic algorithm(GA),in which the fitness function is a suspension quadratic performance index.Comparative simulation shows that the proposed TAEI PID controller can achieve better comprehensive performance,stability,and robustness than a conventional single-acceleration-error-input(SAEI) PID controller for the active suspension. | Yucai Zhou Shian Chen Juncheng Wang | 2014 | Journal of Traffic and Transportation Engineering(English Edition)2014,1,3: | 8 |
| 3 | Large-area straight,regular periodic surface structures produced on fused silica by the interference of two femtosecond laser beams through cylindrical lens显示文摘Inhomogeneity and low efficiency are two important factors that limit the application of laser-induced periodic surface structures(LIPSSs),especially on glass surfaces.In this study,two-beam interference(TBI)of femtosecond lasers was used to produce large-area straight LIPSSs on fused silica using cylindrical lenses.Compared with those produced us-ing a single circular or cylindrical lens,the LIPSSs produced by TBI are much straighter and more regular.Depending on the laser fluence and scanning velocity,LIPSSs with grating-like or spaced LIPSSs are produced on the fused silica sur-face.Their structural colors are blue,green,and red,and only green and red,respectively.Grating-like LIPSS patterns oriented in different directions are obtained and exhibit bright and vivid colors,indicating potential applications in surface coloring and anti-counterfeiting logos. | Long Chen Kaiqiang Cao Yanli Li Jukun Liu Shian Zhang Donghai Feng Zhenrong Sun Tianqing Jia | 2021 | Opto-Electronic Advances2021,4,12: | 7 |

| 6 | Single-shot compressed ultrafast photography: a review显示文摘Compressed ultrafast photography(CUP)is a burgeoning single-shot computational imaging technique that provides an imaging speed as high as 10 trillion frames per second and a sequence depth of up to a few hundred frames.This technique synergizes compressed sensing and the streak camera technique to capture nonrepeatable ultrafast transient events with a single shot.With recent unprecedented technical developments and extensions of this methodology,it has been widely used in ultrafast optical imaging and metrology,ultrafast electron diffraction and microscopy,and information security protection.We review the basic principles of CUP,its recent advances in data acquisition and image reconstruction,its fusions with other modalities,and its unique applications in multiple research fields. | Dalong Qi Shian Zhang Chengshuai Yang Yilin He Fengyan Cao Jiali Yao Pengpeng Ding Liang Gao Tianqing Jia Jinyang Liang Zhenrong Sun Lihong V.Wange | 2020 | Advanced Photonics2020,2,1: | 5 |
| 7 | Prevalence, risk factors, and survival associated with pulmonary hypertension and heart failure among patients with underlying coronary artery disease: a national prospective, multicenter registry study in China显示文摘Background: Coronary artery disease (CAD) is the commonest cause of heart failure (HF), whereas pulmonary hypertension (PH) has not been established or reported in this patient population. Therefore, we assessed the prevalence, risk factors, and survival in CAD-associated HF (CAD-HF) complicated with PH.Methods: Symptomatic CAD-HF patients were continuously enrolled in this prospective, multicenter registry study. Echocardiography, coronary arteriography, left and right heart catheterization (RHC), and other baseline clinical data were recorded. Patients were followed up and their survival was recorded.Results: One hundred and eighty-two CAD-HF patients were enrolled, including 142 with HF with a preserved ejection fraction (heart failure with preserved ejection fraction [HFpEF];left ventricular ejection fraction [LVEF] ≥50%) and 40 with a reduced ejection fraction (heart failure with reduced ejection fraction [HFrEF];LVEF < 50%). PH was diagnosed with RHC in 77.5% of patients. Patients with PH showed worse hemodynamic parameters and higher mortality. HFrEF-PH patients had worse survival than HFpEF-PH patients. CAD-HF patients with an enlarged left ventricular end-diastolic diameter and reduced hemoglobin were at higher risk of PH. Nitrate treatment reduced the risk of PH. Elevated creatinine and mean pulmonary arterial pressure (mPAP), diastolic pressure gradient (DPG) ≥7 mmHg, and previous myocardial infarction (MI) entailed a higher risk of mortality in CAD-HF patients with PH.Conclusions: PH is common in CAD-HF and worsens the hemodynamics and survival in these patients. Left ventricle enlargement and anemia increase the risk of PH in CAD-HF. Patients may benefit from nitrate medications. Renal impairment, elevated mPAP, DPG ≥7 mmHg, and previous MI are strong predictors of mortality in CAD-HF-PH patients.Trial Registration: ClinicalTrials.gov, NCT02164526. | Li Huang Lingpin Pang Qing Gu Tao Yang Wen Li Ruilin Quan Weiqing Su Weifeng Wu Fangming Tang Xiulong Zhu Jieyan Shen Jingzhi Sun Guangliang Shan Changming Xiong Shian Huang Jianguo He | 2022 | Chinese Medical Journal2022,,15: | 4 |
| 8 | Synthesis and Characterization of Niobium-doped TiO_2 Nanotube Arrays by Anodization of Ti-20Nb Alloys显示文摘Well crystallized niobium-doped TiO_2 nanotube arrays(TiNbO-NT) were successfully synthesized via the anodization of titanium/niobium alloy sheets,followed with a heat treatment at 550 C for 2 h.Morphology analysis results demonstrated that both the titanium/niobium alloy microstructure and the dissolution strength of electrolyte played major roles in the formation of nanotube structure.A single-phase microstructure was more favorable to the formation of uniform nanotube arrays,while modulating the dissolution strength of electrolyte was required to obtain nanotube arrays from the alloys with multi-phase microstructures.X-ray diffraction(XRD) and X-ray photoelectron(XPS) analysis results clearly demonstrated that niobium dopants(Nb 5+) were successfully doped into TiO_2 anatase lattice by substituting Ti 4+ in this approach. | Zhengchao Xu Qi Li Shian Gao Jianku Shangi | 2012 | Journal of Materials Science & Technology2012,28,10: | 4 |
| 9 | Valence state manipulation of Sm3+ ions via a phase-shaped femtosecond laser field显示文摘The ability to manipulate the valence state conversion of rare-earth ions is crucial for their applications in color displays, optoelectronic devices, laser sources, and optical memory. The conventional femtosecond laser pulse has been shown to be a well-established tool for realizing the valence state conversion of rare-earth ions, although the valence state conversion efficiency is relatively low. Here, we first propose a femtosecond laser pulse shaping technique for improving the valence state conversion efficiency of rare-earth ions. Our experimental results demonstrate that the photoreduction efficiency from Sm^(3+) to Sm^(2+) in Sm^(3+)-doped sodium aluminoborate glass using a π phase step modulation can be comparable to that using a transform-limited femtosecond laser field, while the peak laser intensity is decreased by about 63%, which is very beneficial for improving the valence state conversion efficiency under the laser-induced damage threshold of the glass sample. Furthermore, we also theoretically develop a(2 + 1)resonance-mediated three-photon absorption model to explain the modulation of the photoreduction efficiency from Sm^(3+)to Sm^(2+)under the π-shaped femtosecond laser field. | YE ZHENG YUNHUA YAO LIANZHONG DENG WENJING CHENG JIANPING LI TIANQING JIA JIANRONG QIU ZHENRONG SUN SHIAN ZHANG | 2018 | Photonics Research2018,6,2: | 4 |
| 10 | Extremely regular periodic surface structures in a large area efficiently induced on silicon by temporally shaped femtosecond laser显示文摘Femtosecond laser-induced periodic surface structures(LIPSS) have several applications in surface structuring and functionalization. Three major challenges exist in the fabrication of regular and uniform LIPSS: enhancing the periodic energy deposition, reducing the residual heat, and avoiding the deposited debris. Herein, we fabricate an extremely regular low-spatial-frequency LIPSS(LSFL) on a silicon surface by a temporally shaped femtosecond laser. Based on a 4 f configuration zero-dispersion pulse shaping system, a Fourier transform limit(FTL) pulse is shaped into a pulse train with varying intervals in the range of 0.25–16.2 ps using periodic π-phase step modulation. Under the irradiation of the shaped pulse with an interval of 16.2 ps, extremely regular LSFLs are efficiently fabricated on silicon. The scan velocity for fabricating regular LSFL is 2.3 times faster, while the LSFL depth is 2 times deeper, and the diffraction efficiency is 3 times higher than those of LSFL using the FTL pulse.The formation mechanisms of regular LSFL have been studied experimentally and theoretically. The results show that the temporally shaped pulse enhances the excitation of surface plasmon polaritons and the periodic energy deposition while reducing the residual thermal effects and avoiding the deposition of the ejected debris, eventually resulting in regular and deeper LSFL on the silicon surface. | YUCHAN ZHANG QILIN JIANG KAIQIANG CAO TIANQI CHEN KE CHENG SHIAN ZHANG DONGHAI FENG TIANQING JIA ZHENRONG SUN JIANRONG QIU | 2021 | Photonics Research2021,9,5: | 4 |

| 13 | Femtosecond laser-induced periodic structures:mechanisms, techniques, and applications显示文摘Over the past two decades,femtosecond laser-induced periodic structures(femtosecond-LIPSs)have become ubiquitous in a variety of materials,including metals,semiconductors,dielectrics,and polymers.Femtosecond-LIPSs have become a useful laser processing method,with broad prospects in adjusting material properties such as structural color,data storage,light absorption,and luminescence.This review discusses the formation mechanism of LIPSs,specifically the LIPS formation processes based on the pump-probe imaging method.The pulse shaping of a femtosecond laser in terms of the time/frequency,polarization,and spatial distribution is an efficient method for fabricating high-quality LIPSs.Various LIPS applications are also briefly introduced.The last part of this paper discusses the LIPS formation mechanism,as well as the high-efficiency and high-quality processing of LIPSs using shaped ultrafast lasers and their applications. | Yuchan Zhang Qilin Jiang Mingquan Long Ruozhong Han Kaiqiang Cao Shian Zhang Donghai Feng Tianqing Jia Zhenrong Sun Jianrong Qiu Hongxing Xu | 2022 | Opto-Electronic Science2022,1,6: | 3 |
| 14 | Single-shot spectral-volumetric compressed ultrafast photography显示文摘In ultrafast optical imaging,it is critical to obtain the spatial structure,temporal evolution,and spectral composition of the object with snapshots in order to better observe and understand unrepeatable or irreversible dynamic scenes.However,so far,there are no ultrafast optical imaging techniques that can simultaneously capture the spatial–temporal–spectral five-dimensional(5D)information of dynamic scenes.To break the limitation of the existing techniques in imaging dimensions,we develop a spectral-volumetric compressed ultrafast photography(SV-CUP)technique.In our SV-CUP,the spatial resolutions in the x,y and z directions are,respectively,0.39,0.35,and 3 mm with an 8.8 mm×6.3 mm field of view,the temporal frame interval is 2 ps,and the spectral frame interval is 1.72 nm.To demonstrate the excellent performance of our SV-CUP in spatial–temporal–spectral 5D imaging,we successfully measure the spectrally resolved photoluminescent dynamics of a 3D mannequin coated with CdSe quantum dots.Our SV-CUP brings unprecedented detection capabilities to dynamic scenes,which has important application prospects in fundamental research and applied science. | Pengpeng Ding Yunhua Yao Dalong Qi Chengshuai Yang Fengyan Cao Yilin He Jiali Yao Chengzhi Jin Zhengqi Huang Li Deng Lianzhong Deng Tianqing Jia Jinyang Liang Zhenrong Sun Shian Zhang | 2021 | Advanced Photonics2021,3,4: | 3 |

| 16 | High-fidelity image reconstruction for compressed ultrafast photography via an augmented-Lagrangian and deep-learning hybrid algorithm显示文摘Compressed ultrafast photography(CUP) is the fastest single-shot passive ultrafast optical imaging technique,which has shown to be a powerful tool in recording self-luminous or non-repeatable ultrafast phenomena.However, the low fidelity of image reconstruction based on the conventional augmented-Lagrangian(AL)and two-step iterative shrinkage/thresholding(Tw IST) algorithms greatly prevents practical applications of CUP, especially for those ultrafast phenomena that need high spatial resolution. Here, we develop a novel AL and deep-learning(DL) hybrid(i.e., AL+DL) algorithm to realize high-fidelity image reconstruction for CUP. The AL+DL algorithm not only optimizes the sparse domain and relevant iteration parameters via learning the dataset but also simplifies the mathematical architecture, so it greatly improves the image reconstruction accuracy. Our theoretical simulation and experimental results validate the superior performance of the AL+DL algorithm in image fidelity over conventional AL and Tw IST algorithms, where the peak signalto-noise ratio and structural similarity index can be increased at least by 4 d B(9 d B) and 0.1(0.05) for a complex(simple) dynamic scene, respectively. This study can promote the applications of CUP in related fields, and it will also enable a new strategy for recovering high-dimensional signals from low-dimensional detection. | CHENGSHUAI YANG YUNHUA YAO CHENGZHI JIN DALONG QI FENGYAN CAO YILIN HE JIALI YAO PENGPENG DING LIANG GAO TIANQING JIA JINYANG LIANG ZHENRONG SUN SHIAN ZHANG | 2021 | Photonics Research2021,9,2: | 2 |
