| 1 | Identification of the surgical indication line for the Denonvilliers’fascia and its anatomy in patients with rectal cancer显示文摘Background:The high rate of urogenital dysfunction after traditional total mesorectal excision(TME)has caused doubts among scholars on the standard fashion of dissection.We have proposed the necessity to preserve the Denonvilliers’fascia in patients with rectal cancer.However,how to accurately locate the Denonvilliers’fascia is unclear.This study aimed to explore anatomical features of the Denonvilliers’fascia by comparing autopsy findings and observations of surgical videos so as to propose a dissection method for the preservation of pelvic autonomic nerves during rectal cancer surgery.Methods:Five adult male cadaver specimens were dissected,and surgical videos of 135 patients who underwent TME for mid-low rectal cancer between January 2009 and February 2019 were reviewed to identify and compare the structure of the Denonvilliers’fascia.Results:The monolayer structure of the Denonvilliers’fascia was observed in 5 male cadaver specimens,and it was located between the rectum,the bottom of the bladder,the seminal vesicles,the vas deferens,and the prostate.The Denonvilliers’fascia was originated from the rectovesical pouch(or rectum-uterus pouch),down to fuse caudally with the rectourethral muscle at the apex of the prostate,and fused to the lateral ligaments on both sides.The fascia was thinner on the midline with a thickness of 1.06±0.10 mm.The crown shape of the Denonvilliers’fascia was slightly triangular,with a height of approximately 5.42±0.16 cm at midline.Nerves were more densely distributed in front of the Denonvilliers’fascia than behind,especially on both sides of it.Under laparoscopic view,the Denonvilliers’fascia was originated at the lowest point of the rectovesical pouch(or rectum-uterus pouch),with a thickened white line which was a good mark for identifying the Denonvilliers’fascia.Conclusion:Identification of the surgical indication line for the Denonvilliers’fascia could help us identify the Denonvilliers’fascia,and it would improve our ability to protect the pelvic autonomic function of patients undergoing TME for rectal cancer. | Jianglong Huang Jing Liu Jiafeng Fang Zongheng Zeng Bo Wei Tufeng Chen Hongbo Wei | 2020 | Cancer Communications2020，40，1： | 10 |
| 2 | A Ka-band Solid-state Transmitter Cloud Radar and Data Merging Algorithm for Its Measurements显示文摘This study concerns a Ka-band solid-state transmitter cloud radar, made in China, which can operate in three different work modes, with different pulse widths, and coherent and incoherent integration numbers, to meet the requirements for cloud remote sensing over the Tibetan Plateau. Specifically, the design of the three operational modes of the radar(i.e., boundary mode M1, cirrus mode M2, and precipitation mode M3) is introduced. Also, a cloud radar data merging algorithm for the three modes is proposed. Using one month's continuous measurements during summertime at Naqu on the Tibetan Plateau,we analyzed the consistency between the cloud radar measurements of the three modes. The number of occurrences of radar detections of hydrometeors and the percentage contributions of the different modes' data to the merged data were estimated.The performance of the merging algorithm was evaluated. The results indicated that the minimum detectable reflectivity for each mode was consistent with theoretical results. Merged data provided measurements with a minimum reflectivity of -35 dBZ at the height of 5 km, and obtained information above the height of 0.2 km. Measurements of radial velocity by the three operational modes agreed very well, and systematic errors in measurements of reflectivity were less than 2 dB. However,large discrepancies existed in the measurements of the linear depolarization ratio taken from the different operational modes.The percentage of radar detections of hydrometeors in mid- and high-level clouds increased by 60% through application of pulse compression techniques. In conclusion, the merged data are appropriate for cloud and precipitation studies over the Tibetan Plateau. | Liping LIU Jiafeng ZHENG Jingya WU | 2017 | Advances in Atmospheric Sciences2017，34，4： | 7 |
| 3 | Emerging CoMn-LDH@MnO2 electrode materials assembled using nanosheets for flexible and foldable energy storage devices显示文摘CoMn layered double hydroxides(CoMn-LDH)are promising electrode materials for supercapacitors because of their excellent cyclic stability.However,they possess relatively low capacitances.In this work,hybrid CoMn-LDH@MnO2 products grown on Ni foams were obtained through a facile hydrothermal method.The as-synthesized samples employed as electrodes deliver a specific capacitance of 2325.01 F g^-1 at 1 A g^-1.An assembled asymmetric supercapacitor using these products as positive electrodes shows a maximum energy density of 59.73 W h kg^-1 at 1000.09 W kg^-1.The prominent electrochemical performance of the as-prepared electrodes could be attributes to hierarchical structures.These findings suggest that hybrid structures might be potential alternatives for future flexible energy storage devices. | Yue Zhao Jiafeng He Meizhen Dai Depeng Zhao Xiang Wu Baodan Liu | 2020 | Journal of Energy Chemistry2020，29，6： | 7 |
| 4 | Designing high-strength titanium alloy using pseudo-spinodal mechanism through diffusion multiple experiment and CALPHAD calculation显示文摘This study used the pseudo-spinodal mechanism to obtain the ultrafineαphase for designing highstrength titanium alloy.Diffusion multiple experiments were designed to find the composition range of TM-x Mo-y V alloy(TM:Ti-4.5 Al-2 Cr-2.5 Nb-2 Zr-1 Sn)for obtaining ultrafineαphase.CALPHAD results confirm that when the alloy composition is located near the intersection of theαandβphase free energy curves,the alloy will undergo pseudo-spinodal transformation and obtain the ultrafineαphase.The designed TM-6 Mo-3 V alloy has a yield strength of 1411 MPa and an elongation of 6.5%.The strength of the alloy depends on the thickness,fraction of theαphase and the solid solution strengthening effect of the alloying elements.The deformation mechanism of the alloy is the dislocation slip of theαandβphases and the twin deformation of theαphase.The large number ofα/βinterfaces produced by the fineαphase is the main reason for limiting the ductility of the alloy.The use of the pseudo-spinodal mechanism combined with diffusion multiple experiments and CALPHAD is an effective method for designing high-strength titanium alloys. | Di Wu Libin Liu Lijun Zeng Wenguang Zhu Wanlin Wang Xiaoyong Zhang Junfeng Hou Baoliang Liu Jiafeng Lei Kechao Zhou | 2021 | Journal of Materials Science & Technology2021，，15： | 3 |
| 5 | Loss of FOXC1 contributes to the corneal epithelial fate switch and pathogenesis显示文摘Forkhead box C1(FOXC1)is required for neural crest and ocular development,and mutations in FOXC1 lead to inherited Axenfeld-Rieger syndrome.Here,we find that FOXC1 and paired box 6(PAX6)are co-expressed in the human limbus and central corneal epithelium.Deficiency of FOXC1 and alternation in epithelial features occur in patients with corneal ulcers.FOXC1 governs the fate of the corneal epithelium by directly binding to lineage-specific open promoters or enhancers marked by H3K4me2.FOXC1 depletion not only activates the keratinization pathway and reprograms corneal epithelial cells into skin-like epithelial cells,but also disrupts the collagen metabolic process and interferon signaling pathways.Loss of interferon regulatory factor 1 and PAX6 induced by FOXC1 dysfunction is linked to the corneal ulcer.Collectively,our results reveal a FOXC1.mediated regulatory network responsible for corneal epithelial homeostasis and provide a potential therapeutic target for corneal ulcer. | Mingsen Li Liqiong Zhu Jiafeng Liu Huaxing Huang Huizhen Guo Li Wang Lingyu Li Sijie Gu Jieying Tan Jing Zhong Bowen Wang Zhen Mao Yong Fan Chunqiao Liu Jin Yuan Hong Ouyang | 2021 | Signal Transduction and Targeted Therapy2021，6，2： | 2 |
| 6 | The Class Ⅲ peroxidase gene OsPrx30,transcriptionally modulated by the AT-hook protein OsATH1, mediates rice bacterial blight-induced ROS accumulation显示文摘Class Ⅲ peroxidases(CⅢ Prxs) play critical roles in plant immunity by scavenging reactive oxygen species(ROS). However, the functions of CⅢ Prxs in rice(Oryza sativa L.) immunity are largely unexplored. Here, we report a Prx precursor, OsPrx30,that is responsive to the bacterial blight Xanthomonas oryzae pv. oryzae(Xoo). OsPrx30 was primarily expressed in rice roots, leaves, and stems,and its protein product was mainly localized at the endoplasmic reticulum. Overexpression of OsPrx30 enhanced the plant’s susceptibility to Xoo by maintaining a high level of peroxidase(POD) activity and reducing the content of H2O2, whereas depletion of OsPrx30 had the opposite effects. Furthermore, we identified an AT-hook transcription factor, Os ATH1, that is specifically bound to the OsPrx30 promoter. As observed in plants overexpressing OsPrx30, depletion of Os ATH1 enhanced susceptibility to Xoo. Finally, we demonstrated that depletion of Os ATH1 increased histone H3 acetylation at the AT-rich region of the OsPrx30 promoter.Taken together, these results reveal a mechanism underlying the POD-induced natural resistance to bacterial diseases and suggest a model for transcription regulation of Prx genes in rice. | Hao Liu Shuangyu Dong Ming Li Fengwei Gu Guili Yang Tao Guo Zhiqiang Chen Jiafeng Wang | 2021 | Journal of Integrative Plant Biology2021，63，2： | 2 |

| 8 | Modulation Recognition of Radio Signals Based on Edge Computing and Convolutional Neural Network显示文摘Software defined radio(SDR)is a wireless communication technology that uses modern software to control the traditional“pure hardware circuit”.It can provide an effective and secure solution to the problem of building multi-mode,multi-frequency and multifunction wireless communication equipment.Although the concept and application of SDR have been studied a lot,there is little discussion about the operating efficiency of the established system.For the purpose of shortening the delay of mapping and reducing the high computing load in the cloud,a radio monitoring system based on edge computing is developed to achieve the flexible,extensible and real-time monitoring of high-performance SDR applications.To promote the edge intelligence of deep learning(DL)service deployment through edge computing(EC),we developed an edge intelligence algorithm of convolutional neural network(CNN)based on attention mechanism to carry out modulation recognition(MR)of the edge signal and make MR closer to the antenna terminal.Through the experiment of the system and the edge algorithm,this thesis verifies the effectiveness of the developed multifunction radio signal monitoring system. | Jiyu Jiao Xuehong Sun Yanpeng Zhang Liping Liu Jianfeng Shao Jiafeng Lyu Liang Fang | 2021 | Journal of Communications and Information Networks2021，6，3： | 1 |
| 9 | Understanding the pattern and mechanism of spatial concentration of urban land use, population and economic activities: a case study in Wuhan, China显示文摘Quantifying the aggregation patterns of urban population, economic activities, and land use are essential for understanding compact development, but little is known about the difference among the distribution characteristics and how the built environment influences urban aggre-gation. In this study, five elements are collected in Wuhan, China, namely population density, floor area ratio, business POIs, road network and built-up area as the representative of urban population, economic activities and land use. An inverse S-shape function is employed to fit the elements’ macro distribution. An aggregation degree index is proposed to measure the aggregation level of urban elements. The kernel density estimation is used to identify the aggregation patterns. The spatial regression model is used to identify the built environment factors influencing the spatial distribution of urban elements. Results indicates that all urban elements decay outward from the city center in an inverse S-shape manner. The business Pointof- Interest (POI) density and population density are highly aggregated;floor area ratio and road density are moderately aggregated, whereas the built-up density is poorly aggregated. Three types of spatial aggregation patterns are identified: a point-shaped pattern, an axial pattern and a planar pattern. The spatial regression modeling shows that the built environment is associated with the distribution of the urban population, economic activities and land use. Destination accessibility factors, transit accessibility factors and land use diversity factors shape the distribution of the business POI density, floor area ratio and road density. Design factors are positively associated with population density, floor area ratio and built-up density. Future planning should consider the varying spatial concentration of urban population, economic activities and land use as well as their relationships with built environment attributes. Results of this study will provide a systematic understanding of aggregation of urban land use, popula-tion, and economic activities in megacities as well as some suggestions for planning and compact development. | Zehui Li Limin Jiao Boen Zhang Gang Xu Jiafeng Liu | 2021 | Geo-Spatial Information Science2021，24，4： | 1 |

| 12 | An on-line free handwritten Chinese character recognition method based on component cascaded HMMs显示文摘This paper presents a cascaded Hidden Markov Model (HMM), which allows state's transition, skip and duration. The cascaded HMM extends the way of HMM pattern description of Handwritten Chinese Character (HCC) and depicts the behavior of handwritten curve more reliably in terms of the statistic probability. Hence character segmentation and labeling are unnecessary. Viterbi algorithm is integrated in the cascaded HMM after the whole sample sequence of a HCC is input. More than 26,000 component samples are used for training 407 handwritten component HMMs. At the improved training stage 94 models of 94 Chinese characters are gained by 32,000 samples. Compared with the Segment HMMs approach, the recognition rate of this model for the first candidate is 87.89% and the error rate could be reduced by 12.4%. | Zhao Wei(赵巍) Liu Jiafeng Tang Xianglong | 2005 | High Technology Letters2005，11，3： | 1 |
| 13 | Growth of BiOBr/ZIF‑67 Nanocomposites on Carbon Fiber Cloth as Filter‑Membrane‑Shaped Photocatalyst for Degrading Pollutants in Flowing Wastewater显示文摘BiOBr-based nanocomposite photocatalysts are used for removing the organic pollutants,but their poor adsorption/photocatalytic performances and the low potential for recycling limit their application.To solve the issue,herein we report a large-area recyclable CFC/BiOBr/ZIF-67 filter-membrane-shaped photocatalyst prepared by in situ growth of BiOBr/ZIF-67 nanocomposites on carbon fiber cloth(CFC).Fabrication process is based on hydrothermal synthesis of BiOBr nanosheets(diameter 0.5–1μm)on carbon fiber cloth(as substrate material)and then a chemical bath route is used to grow ZIF-67 nanoparticles(diameter 300–600 nm)in situ on the surface of CFC/BiOBr.Resulted composite,CFC/BiOBr/ZIF-67,exhibits a high specific surface area(545.82 m^(2) g^(−1))and a wide photoabsorption,accompanied by an absorption edge(~620 nm).In dark condition,CFC/BiOBr/ZIF-67 adsorbs bisphenol A(BPA)and orange 7(AO7)within 60 min,respectively with 20.0% and 40.1% efficiency.This level of efficiencies are correspondingly 2.6 and 3.2 times more that of the bare CFC/BiOBr(7.6%for BPA and 12.4% for AO7).Under visible light irradiation,CFC/BiOBr/ZIF-67 can degrade 69.7% of BPA and 96.0% of AO7,in 120 min,which are,respectively,1.3 and 1.8 times higher than the absorption efficiency of bare CFC/BiOBr(53.2% for BPA,52.0% for AO7).When CFC/BiOBr/ZIF-67 is used as a filter membrane for photocatalytic removal of pollutants in flowing wastewater(AO7,rate:~1.5 L h^(−1)),92.2%of AO7 can be decomposed after 10 filtering cycles.This study suggests CFC/BiOBr/ZIF-67 as a novel highly functional,recyclable and environmental friendly photo-driven membrane filter for purification and recovery of flowing surface waste waters. | Xiaolong Li Ting Liu Yan Zhang Jiafeng Cai Mengqiang He Maoquan Li Zhigang Chen Lisha Zhang | 2022 | Advanced Fiber Materials2022，4，6： | 1 |
| 14 | Feature extraction for classification of different weather conditions显示文摘Classification of different weather conditions provides a first step support for outdoor scene modeling,which is a core component in many different applications of outdoor video analysis and computer vision.Features derived from intrinsic properties of the visual effects of different weather conditions contribute to successful classification.In this paper,features representing both the autocorrelation of pixel-wise intensities over time and the max directional length of rain streaks or snowflakes are proposed.Based on the autocorrelation of each pixel’s intensities over time,two temporal features are used for coarse classification of weather conditions according to their visual effects.On the other hand,features are extracted for fine classification of video clips with rain and snow.The classification results on 249 video clips associated with different weather conditions indicate the effectiveness of the extracted features,by using C-SVM as the classifier. | Xudong ZHAO Peng LIU Jiafeng LIU Xianglong TANG | 2011 | Frontiers of Electrical and Electronic Engineering in China2011，6，2： | 1 |

| 18 | A reciprocating motion-driven rotation mechanism for the ATP synthase显示文摘The ATP synthase(having a typical subunit composition of ?3?3???ab2c8-15) employs an intriguing rotary mechanism for the generation of ATP from ADP and Pi, using energy stored in a transmembrane proton gradient. The conventional rotary model, although being generally accepted, remains difficult to explain certain experimental observations. Here we propose an alternative rotary model for the ATP synthase such that what rotates is the catalytic ?3?3 cylinder rather than the central stalk and the membrane-embedded c-ring. Specifically, the membrane translocation of protons would induce a cycled conformational change in the c-ring, leading to a reciprocating motion of the attached central stalk, which in turn drives the unidirectional rotation of the ?3?3 cylinder. Such a reciprocating motion-driven rotation mechanism is somehow analogous to the working mechanism of a retractable click ballpoint pen. Our new model not only explains the experimental observations that have been difficult to reconcile with the conventional model but also avoids its theoretical illogicality. | Jiafeng Liu Xinmiao Fu Zengyi Chang | 2016 | Science China(Life Sciences)2016，59，1： | 0 |

| 20 | Preparation of Photo-responsive DNA Supramolecular Hydrogels and Their Application as UV Radiometers显示文摘Ultraviolet light(UV)is an essential component of ambient light,but high dose UV would damage genome DNA.While semiconductors and soft materials have been employed to detect the UV,the complex process and the instrumental requirement have limited the application in daily life.In this study,taking advantage of sequence designability,a series of hydrogels with different gel-sol transition rates was constructed under the same UV intensity by introducing competing hybridization to tune the stability of the molecular network.Through estimating the transition time between each system under UV light irradiation,the intensity of UV could be roughly estimated,which provided a convenient method for the visual detection of UV. | DING Yuqiao LI Yujie YANG Bo PAN Yufan CHENG Jiafeng MENG Siwen LIU Dongsheng XU Lijin DONG Yuanchen | 2023 | Chemical Research in Chinese Universities2023，39，1： | 0 |
