| 2 | Oversample Reconstruction Based on a Strong Inter-Diagonal Matrix for an Optical Microscanning Thermal Microscope Imaging System显示文摘Based on a strong inter-diagonal matrix and Taylor series expansions,an oversample reconstruction method was proposed to calibrate the optical micro-scanning error. The technique can obtain regular 2 ×2 microscanning undersampling images from the real irregular undersampling images,and can then obtain a high spatial oversample resolution image. Simulations and experiments show that the proposed technique can reduce optical micro-scanning error and improve the system's spatial resolution. The algorithm is simple,fast and has low computational complexity. It can also be applied to other electro-optical imaging systems to improve their spatial resolution and has a widespread application prospect. | Meijing Gao Ailing Tan Jie Xu Weiqi Jin Zhenlong Zu Ming Yang | 2018 | Journal of Beijing Institute of Technology2018，27，1： | 0 |
| 3 | Dithizone-functionalized C18 online solid-phase extraction-HPLC-ICP-MS for speciation of ultra-trace organic and inorganic mercury in cereals and environmental samples显示文摘A simple and efficient dithizone-functionalized solid-phase extraction(SPE)procedure,online coupled with high-performance liquid chromatography(HPLC)-inductively coupled plasma mass spectrometry,was developed for the first time for enrichment and determination of ultra-trace mercury(Hg)species(inorganic divalent Hg(Hg(Ⅱ)),methylmercury(CH_(3)Hg(Ⅱ))and ethylmercury(C_(2)H_(5)Hg(Ⅱ))in cereals and environmental samples.In the proposed method,functionalization of the commercial C_(18) column with dithizone,enrichment,and elution of the above Hg species can be completed online with the developed SPE device.A simple solution of 2-mercaptoethanol(1%(V/V))could be used as an eluent for both the SPE and HPLC separation of Hg species,significantly simplifying the method and instrumen-tation.The online SPE method was optimized by varying dithizone dose,2-mercaptoethanol concentration,and sample volume.In addition,the effect of pH,coexisting interfering ions,and salt effect on the enrichment was also discussed.Under the optimized conditions,the detection limits of Hg species for 5 mL water sample were 0.15 ng/L for Hg(Ⅱ),0.07 ng/L for CH_(3)Hg(Ⅱ),and 0.04 ng/L for C_(2)H_(5)Hg(Ⅱ)with recoveries in the range of 85%-100%.The developed dithizone-functionalized C_(18) SPE column can be reused after a single function-alization,which significantly simplifies the enrichment step.Moreover,the stability of Hg species enriched on the SPE column demonstrated its suitability for field sampling of Hg species for later laboratory analysis.This environment-friendly method offers a robust tool to detect ultra-trace Hg species in cereals and environmental samples. | Ying Wang Ailing Zhu Yingying Fang Changjun Fan Yanli Guo Zhiqiang Tan Yongguang Yin Yong Cai Guibin Jiang | 2022 | Journal of Environmental Sciences2022，34，5： | 0 |

| 5 | Identifying a confused cell identity for esophageal squamous cell carcinoma显示文摘The cell identity of malignant cells and how they acquire it are fundamental for our understanding of cancer.Here,we report that esophageal squamous cell carcinoma(ESCC)cells display molecular features equally similar but distinct to all three types of normal esophageal epithelial cells,which we term as confused cell identity(CCI).CCI is an independent prognostic marker associated with poor prognosis in ESCC.Further,we identify tropomyosin 4(TPM4)as a critical CCI gene that promotes the aggressiveness of ESCC in vitro and in vivo.And TPM4 creates CCI through activating the Jak/STAT-SOX2 pathway.Thus,our study suggests an unrecognized feature of ESCC cells,which might be of value for clinic prognosis and potential interference. | Xiangyu Pan Jian Wang Linjie Guo Feifei Na Jiajia Du Xuelan Chen Ailing Zhong Lei Zhao Lu Zhang Mengsha Zhang Xudong Wan Manli Wang Hongyu Liu Siqi Dai Ping Tan Jingyao Chen Yu Liu Bing Hu Chong Chen | 2022 | Signal Transduction and Targeted Therapy2022，7，5： | 0 |
