1An experiment-library least-squares method on on-line coal element contents analysis显示文摘A new experiment-library least-squares(experiment-LLs) method used in the neutron inelastic-scattering and thermal-capture analysis(NITA) technique for on-line coal analysis was developed,which has significantly decreased the non-linear radiation effects.In this method,sixty samples with preset elemental contents were made,from whose experimental spectra twenty single-element spectrum libraries corresponding to twenty kinds of coal were built using the least-squares method.The spectrum of the unknown sample was analyzed based on these twenty libraries to estimate its element contents.With the initial estimated result,the procedure of developing library and analysis was iterated to build a new library with the closest element contents to the unknown sample.Hence the experiment-LLs method can reduce non-linear radiation effects.The experiment-LLs method was performed on an improved coal analysis system which was equipped with a long-life 14 MeV pulsed-neutron generator,a bulk BGO detector with a temperature controller,a moisture meter and coal-smoothing device.The precisions of this system for ash content,water content,volatile content and calorific value have reached 1.0wt%,0.5wt%,1.0wt%,350 kJ/kg,respectively.WANG HuiDong LU JingBin LU YuPing YANG Dong MA KeYan YANG Kang LIU YuMin CHENG DaoWen 2012Science China(Physics,Mechanics & Astronomy)2012,55,11:6
2Synthesis and assembly with mesoporous silica of platinum (Ⅱ) porphyrin complexes bearing carbazyl groups: Luminescent and oxygen sensing properties显示文摘A series of platinum meso-tetrakis [3-methoxy-4-(N-carbazyl)n-alkyloxyphenyl]porphyrin (Pt-4Cn-TPP, n = 4, 6 and 8) are synthesized. Pt-4C4-TPP, Pt-4C6-TPP and Pt-4C8-TPP exhibit similar luminescent properties in solution and solid state. Three protonated platinum (II) porphyrins are assembled with mesoporous silica MCM-48, respec- tively, resulting in assembly materials Pt-4Cn-TPP4+/ MCM-48 (n = 4, 6 and 8). The luminescent intensity of Pt-4Cn-TPP4+/MCM-48 can be extremely quenched by molecular oxygen with high sensitivity (I0/I100 > 9). The Stern-Volmer plots of these assembly materials display considerable linearity within a wide range of oxygen concentration (0 to 100%). The re- sponse time is all ≤ 1 s and recovery time ≤ 22 s for these assembly materials.HUO Cheng ZHANG Huidong GUO Jianhua ZHANG Hongyu ZHANG Ping WANG Yue 2006Chinese Science Bulletin2006,51,19:3

9Deep Learning‑Assisted Quantitative Susceptibility Mapping as a Tool for Grading and Molecular Subtyping of Gliomas显示文摘This study aimed to explore the value of deep learning(DL)-assisted quantitative susceptibility mapping(QSM)in glioma grading and molecular subtyping.Forty-two patients with gliomas,who underwent preoperative T2 fluid-attenuated inversion recovery(T2 FLAIR),contrast-enhanced T1-weighted imaging(T1WI+C),and QSM scanning at 3.0T magnetic resonance imaging(MRI)were included in this study.Histopathology and immunohistochemistry staining were used to determine glioma grades,and isocitrate dehydrogenase(IDH)1 and alpha thalassemia/mental retardation syndrome X-linked gene(ATRX)subtypes.Tumor segmentation was performed manually using Insight Toolkit-SNAP program(www.itksnap.org).An inception convolutional neural network(CNN)with a subsequent linear layer was employed as the training encoder to capture multi-scale features from MRI slices.Fivefold cross-validation was utilized as the training strategy(seven samples for each fold),and the ratio of sample size of the training,validation,and test dataset was 4:1:1.The performance was evalu-ated by the accuracy and area under the curve(AUC).With the inception CNN,single modal of QSM showed better perfor-mance in differentiating glioblastomas(GBM)and other grade gliomas(OGG,grade II–III),and predicting IDH1 mutation and ATRX loss(accuracy:0.80,0.77,0.60)than either T2 FLAIR(0.69,0.57,0.54)or T1WI+C(0.74,0.57,0.46).When combining three modalities,compared with any single modality,the best AUC/accuracy/F1-scores were reached in grading gliomas(OGG and GBM:0.91/0.89/0.87,low-grade and high-grade gliomas:0.83/0.86/0.81),predicting IDH1 mutation(0.88/0.89/0.85),and predicting ATRX loss(0.78/0.71/0.67).As a supplement to conventional MRI,DL-assisted QSM is a promising molecular imaging method to evaluate glioma grades,IDH1 mutation,and ATRX loss.Wenting Rui Shengjie Zhang Huidong Shi Yaru Sheng Fengping Zhu YiDi Yao Xiang Chen Haixia Cheng Yong Zhang Ababikere Aili Zhenwei Yao Xiao‑Yong Zhang Yan Ren 2023Phenomics2023,3,3:0
10Mediator complex components are frequent targets for genetic alterations in various types of human cancer显示文摘The Mediator co-activator complex is a highly conserved,multisubunit protein complex required for gene transcription by RNA polymerase Ⅱ(RNAPⅡ)in all eukaryotes(Allen and Taatjes,2015).This complex,which consists of at least 30 polypeptides,can be divided into four structurally distinct sub-modules including the head,middle,tail,and cyclin-dependent kinase 8(CDK8)Libin Deng Cheng Zhang Duling Miao Xiaoli Tang Shiwen Luo Hong-Bo Xin Huidong Shi 2017Journal of Genetics and Genomics2017,44,12:0
