| 1 | Experimental Study on Interaction Between Degrees of Freedom in a Wave Buoy显示文摘Increasing degrees of freedom(DOFs)is a useful way to raise the power capture efficiency of oscillating wave energy converters.Thus,this study proposes a buoy with three DOFs,which are surge,heave,and pitch.The hydrodynamic performance and power capture efficiency of the buoy is physically modeled.Amplitudes of unidirectional and coupled motions are compared to analyze the interaction effect between freedoms under conditions with and without power take-off damping.The capture width ratio and corresponding growth rates are also calculated.Results show that the buoy makes a periodic sinusoidal(or approximate)movement in every DOF.Coupling effect can cause an increase in the amplitude in one DOF and a decrease in the amplitudes of the others.This phenomenon shows that the kinematic energy of the buoy redistributes to all DOFs compared with the unidirectional conditions.Adding DOFs can improve the power absorption of the buoy in most cases,but the number of DOFs is not the more the better. | HUANG Shuting SHI Hongda CAO Feifei TAN Junzhe CHENG Haixun LI Demin LIU Shangze GONG Haoxiang TAO Ji | 2019 | Journal of Ocean University of China2019，18，6： | 5 |
| 2 | Phase group synchronization between any signals and its physical characteristics显示文摘The phase group synchronization between any signals is further revealed,which is based on proposing the new concepts of the greatest common factor frequency,the least common multiple period,quantized phase shift resolution,equivalent phase comparison frequency and so on.Then the problem of phase comparison and processing between different frequency signals is solved and shown in detail.Using the basic principle and the variation law of group phase difference,the frequency stability better than 10-14/s can be easily obtained in the time&frequency measurement and control domain,and experimental results also show the phase relations between atomic energy level transition signal and the locked crystal oscillator signal in an active hydrogen atomic clock are strict phase group synchronization,and locked precision with 10-13/s can be reached based on phase group synchronization.The phase group synchronization can provide technical support to frequency linking among radio frequency,microwave and light frequency. | DU BaoQiang SHI LinLin CHEN YaoMing DONG ShaoFeng YANG ZhiGang CAO LingZhi GUO ShuTing | 2014 | Science China(Physics,Mechanics & Astronomy)2014，57，4： | 2 |
| 3 | RNA Methylome Reveals the m^(6)A-mediated Regulation of Flavor Metabolites in Tea Leaves under Solar-withering显示文摘The epitranscriptomic mark N6-methyladenosine(m^(6)A),which is the predominant internal modification in RNA,is important for plant responses to diverse stresses.Multiple environmental stresses caused by the tea-withering process can greatly influence the accumulation of specialized metabolites and the formation of tea flavor.However,the effects of the m^(6)A-mediated regulatory mechanism on flavor-related metabolic pathways in tea leaves remain relatively uncharacterized.We performed an integrated RNA methylome and transcriptome analysis to explore the m^(6)Amediated regulatory mechanism and its effects on flavonoid and terpenoid metabolism in tea(Camellia sinensis)leaves under solar-withering conditions.Dynamic changes in global m^(6)A level in tea leaves were mainly controlled by two m^(6)A erasers(CsALKBH4A and CsALKBH4B)during solar-withering treatments.Differentially methylated peak-associated genes following solarwithering treatments with different shading rates were assigned to terpenoid biosynthesis and spliceosome pathways.Further analyses indicated that CsALKBH4-driven RNA demethylation can directly affect the accumulation of volatile terpenoids by mediating the stability and abundance of terpenoid biosynthesis-related transcripts and also indirectly influence the flavonoid,catechin,and theaflavin contents by triggering alternative splicing-mediated regulation.Our findings revealed a novel layer of epitranscriptomic gene regulation in tea flavor-related metabolic pathways and established a link between the m^(6)A-mediated regulatory mechanism and the formation of tea flavor under solar-withering conditions. | Chen Zhu Shuting Zhang Chengzhe Zhou Caiyun Tian Biying Shi Kai Xu Linjie Huang Yun Sun Yuling Lin Zhongxiong Lai Yuqiong Guo | 2023 | Genomics, Proteomics & Bioinformatics2023，21，4： | 2 |
| 4 | Enhanced electrochemical performance of La_(0.6)Sr_(0.4)Co_(0.2)Fe_(0.8)O_(3−δ)cathode via Ba-doping for intermediate-temperature solid oxide fuel cells显示文摘La_(0.6)Sr_(0.4)Co_(0.2)Fe_(0.8)O_(3-δ)(LSCF)is recognized as one of the most promising cathode materials for the highly-desired intermediatetemperature solid oxide fuel cell(IT-SOFC)technology.However,it is still challenged by polarization losses due to reduced operation temperatures.In this work,a series of Ba^(2+)-doped La0.6-xBaxSr0.4Co0.2Fe0.8O3-δ(LBSCFx,x=0.05,0.10,0.15,and 0.20)materials are successfully synthesized and their electrochemical performances are evaluated as a cathode for IT-SOFC technology.The study shows that,compared to the un-doped LSCF,the Ba^(2+)-doped LBSCF possess higher electrical conductivities at 500-800℃ and display lower polarization resistances to oxygen adsorption/dissociation.As a result,the Ni-SDC|SDC|LBSCF0.20 cell(SDC=samarium-doped cerium,Sm_(0.2)Ce_(0.8)O_(1.9))delivers a high maximum power density of 0.704 W/cm^(2)at 750℃,which is>30%higher than the Ni-SDC|SDC|LSCF cell.This work reveals that Ba^(2+)-doping is effective in enhancing oxygen catalytic activity of LSCF-based cathode materials,demonstrating a new and commercial-feasible strategy in developing high performance cathode materials for the IT-SOFC technology. | Changkun Cai Manyi Xie Ke Xue Yu Shi Shuting Li Yuanyuan Liu Shengli An Hong Yang | 2022 | Nano Research2022，15，4： | 1 |
| 5 | Influence of yttrium on purification and carbide precipitation of superalloy K4169显示文摘The effect of reactive element yttrium on purification and carbide precipitation of superalloy K4169 has been studied through vacuum induction melting.The results show that yttrium has a strong deoxidizing and desulfurizing ability,and the impurity elements of sulfur and oxygen in melting K4169 are greatly reduced to 2-5 ppm and 4-5 ppm,respectively.The metallurgical reaction product is mainly Y_(2)O_(3)and yttrium containing sulfides have not been observed.With the increase of the content of yttrium from0.005 wt.%to 0.033 wt.%,the morphology and size of MC carbides in casting are significantly influenced due to that the yttrium changes the diffusion of the carbide forming elements and solid fraction during solidification.In the alloys without yttrium,only isolated blocky or strip carbides exist,while skeletonlike carbides are observed in the alloys with yttrium.Both the average size and the number density of skeleton carbides decrease monotonously with yttrium content increasing.After yttrium increasing to 0.033 wt.%,a phase of hexagonal Ni17 Y2 is observed to precipitate in the form of symbiosis with MC carbide and matrix.The addition of yttrium is not beneficial for the properties of K4169 alloys at the room temperature,which is quite related to the MC carbides with a large skeleton-like morphology through the analysis of tensile fracture. | Shuting Cao Yaqian Yang Bo Chen Kui Liu Yingche Ma Leilei Ding Junjie Shi | 2021 | Journal of Materials Science & Technology2021，，27： | 1 |

| 7 | Host protection against Omicron BA.2.2 sublineages by prior vaccination in spring 2022 COVID-19 outbreak in Shanghai显示文摘The Omicron family of SARS-CoV-2 variants are currently driving the COVID-19 pandemic.Here we analyzed the clinical laboratory test results of 9911 Omicron BA.2.2 sublineages-infected symptomatic patients without earlier infection histories during a SARS-CoV-2 outbreak in Shanghai in spring 2022.Compared to an earlier patient cohort infected by SARS-CoV-2 prototype strains in 2020,BA.2.2 infection led to distinct fluctuations of pathophysiological markers in the peripheral blood.In particular,severe/critical cases of COVID19 post BA.2.2 infection were associated with less pro-inflammatory macrophage activation and stronger interferon alpha response in the bronchoalveolar microenvironment.Importantly,the abnormal biomarkers were significantly subdued in individuals who had been immunized by 2 or 3 doses of SARS-CoV-2 prototypeinactivated vaccines,supporting the estimation of an overall 96.02% of protection rate against severe/critical disease in the 4854 cases in our BA.2.2 patient cohort with traceable vaccination records.Furthermore,even though age was a critical risk factor of the severity of COVID-19 post BA.2.2 infection,vaccination-elicited protection against severe/critical COVID-19 reached 90.15% in patients aged≥60 years old.Together,our study delineates the pathophysiological features of Omicron BA.2.2 sublineages and demonstrates significant protection conferred by prior prototype-based inactivated vaccines. | Ziyu Fu Dongguo Liang Wei Zhang Dongling Shi Yuhua Ma Dong Wei Junxiang Xi Sizhe Yang Xiaoguang Xu Di Tian Zhaoqing Zhu Mingquan Guo Lu Jiang Shuting Yu Shuai Wang Fangyin Jiang Yun Ling Shengyue Wang Saijuan Chen Feng Liu Yun Tan Xiaohong Fan | 2023 | Frontiers of Medicine2023，17，3： | 1 |
| 8 | New Discovery of Upper Crustal High-and Low-Velocity Belts and High-Velocity Core in the Tarim Basin显示文摘The Tarim Basin is the biggest oil-and gas-bearing basin in China,which has undergone long-term and complicated evolutionary history.During each evolutional stage and in different sub-basins in the same stage,the Tarim Basin has different proto-types,and it is thus named a composite and superimposed basin.A study on the basement nature of such a complex but significant to the national oil and gas strategy basin is of great significance(Huang Chenjun et al.,2017).Based on earthquake data,detailed velocity structure of deep basin can be obtained in order to research the basement nature. | WANG Tengfei JIN Zhenkui YU Xiaoxia CHENG Rihui SONG Xue YANG Baoju LI Shuo SHI Shuting | 2019 | Acta Geologica Sinica(English Edition)2019，93，1： | 0 |
| 9 | Transcriptomic and genetic approaches reveal that low-light-induced disease susceptibility is related to cellular oxidative stress in tomato显示文摘The impact of low light intensities on plant disease outbreaks represents a major challenge for global crop security,as it frequently results in significant yield losses.However,the underlying mechanisms of the effect of low light on plant defense are still poorly understood.Here,using an RNA-seq approach,we found that the susceptibility of tomato to Pseudomonas syringae pv.tomato DC3000(Pst DC3000)under low light was associated with the oxidation-reduction process.Low light conditions exacerbated Pst DC3000-induced reactive oxygen species(ROS)accumulation and protein oxidation.Analysis of gene expression and enzyme activity of ascorbate peroxidase 2(APX2)and other antioxidant enzymes revealed that these defense responses were significantly induced by Pst DC3000 inoculation under normal light,whereas these genes and their associated enzyme activities were not responsive to pathogen inocula-tion under low light.Additionally,the reduced ascorbate to dehydroascorbate(AsA/DHA)ratio was lower under low light compared with normal light conditions upon Pst DC3000 inoculation.Furthermore,the apx2 mutants generated by a CRISPR-Cas9 gene-editing approach were more susceptible to Pst DC3000 under low light conditions.Notably,this increased susceptibility could be significantly reduced by exogenous AsA treatment.Collectively,our findings suggest that low-light-induced disease susceptibility is associated with increased cellular oxidative stress in tomato plants.This study sheds light on the intricate relationship between light conditions,oxidative stress,and plant defense responses,and may pave the way for improved crop protection strategies in low light environments. | Qian Luo Jiao Wang Ping Wang Xiao Liang Jianxin Li Changqi Wu Hanmo Fang Shuting Ding Shujun Shao Kai Shi | 2023 | Horticulture Research2023，10，10： | 0 |

| 13 | Revisiting the ionic diffusion mechanism in Li_(3)PS_(4) via the joint usage of geometrical analysis and bond valence method显示文摘Inorganic solid electrolytes have obvious advantages on safety and electrochemical stability compared to organic liquid electrolytes,but the advance on high ionic conductivity of typical electrolytes is still undergoing.Although the first-principles calculation in the ion migration simulation is an important strategy to develop high-performance solid electrolyte,the process is very time-consuming.Here,we propose an effective method by combining the geometrical analysis and bond valance sum calculation to obtain an approximate minimum energy path preliminarily,in parallel to pave the way for the interoperability of low-precision and high-precision ion transport calculation.Taking a promising electrolyte Li_(3)PS_(4) as an example,we revisit its Li-ionic transport behavior.Our calculated Li-ion pathways and the activation energies(the corresponding values:1.09 eV vs.0.88 eV vs.0.86 eV)in γ-,β- and α-Li_(3)PS_(4) are consistent with the ones obtained from the first-principles calculations.The variations of the position of P-ions lead the rearrangement of the host PS_(4) tetrahedron,affecting the diffusion positions of Li-ions and further enabling high Li^(+) conductivity in β-Li_(3)PS_(4). | Li Pan Liwen Zhang Anjiang Ye Shuting Chi Zheyi Zou Bing He Lanli Chen Qian Zhao Da Wang Siqi Shi | 2019 | Journal of Materiomics2019，5，4： | 0 |
| 14 | Audio-Text Multimodal Speech Recognition via Dual-Tower Architecture for Mandarin Air Traffic Control Communications显示文摘In air traffic control communications (ATCC), misunderstandings between pilots and controllers could result in fatal aviation accidents. Fortunately, advanced automatic speech recognition technology has emerged as a promising means of preventing miscommunications and enhancing aviation safety. However, most existing speech recognition methods merely incorporate external language models on the decoder side, leading to insufficient semantic alignment between speech and text modalities during the encoding phase. Furthermore, it is challenging to model acoustic context dependencies over long distances due to the longer speech sequences than text, especially for the extended ATCC data. To address these issues, we propose a speech-text multimodal dual-tower architecture for speech recognition. It employs cross-modal interactions to achieve close semantic alignment during the encoding stage and strengthen its capabilities in modeling auditory long-distance context dependencies. In addition, a two-stage training strategy is elaborately devised to derive semantics-aware acoustic representations effectively. The first stage focuses on pre-training the speech-text multimodal encoding module to enhance inter-modal semantic alignment and aural long-distance context dependencies. The second stage fine-tunes the entire network to bridge the input modality variation gap between the training and inference phases and boost generalization performance. Extensive experiments demonstrate the effectiveness of the proposed speech-text multimodal speech recognition method on the ATCC and AISHELL-1 datasets. It reduces the character error rate to 6.54% and 8.73%, respectively, and exhibits substantial performance gains of 28.76% and 23.82% compared with the best baseline model. The case studies indicate that the obtained semantics-aware acoustic representations aid in accurately recognizing terms with similar pronunciations but distinctive semantics. The research provides a novel modeling paradigm for semantics-aware speech recognition in air traffic control communications, which could contribute to the advancement of intelligent and efficient aviation safety management. | Shuting Ge Jin Ren Yihua Shi Yujun Zhang Shunzhi Yang Jinfeng Yang | 2024 | Computers, Materials & Continua2024，78，3： | 0 |
| 15 | Polyoxometalate-Based Porous Metal-Organic Gel for High-Efficiency Ultrasound-Assisted Oxidative Desulfurization of Model Fuel显示文摘A novel heterogeneous catalyst for ultrasound-assisted oxidative desulfurization(UAODS)was designed and synthesized by confining polyoxometalates(POMs)clusters within porous metal-organic gel.The catalyst microstructures were characterized by XRD,SEM-EDX,FT-IR,N_(2)adsorption-desorption,and XPS.Effects of POM loading,catalyst dosage,and ultrasonic power were also investigated.Results indicate that 60%-PMA@MOX(Al)exhibits optimal catalytic activity,with a sulfur removal rate of 98.61%and excellent reusability.Moreover,a kinetic study of different desulfurization approaches demonstrates that the unique thermal and cavitation effects of ultrasound can effectively improve the efficiency of oxidative desulfurization. | Ji Haifeng Liu Shuting Shi Hongfei Wang Weidong | 2022 | China Petroleum Processing & Petrochemical Technology2022，24，3： | 0 |
