| 2 | Target alignment in the Shen-Guang Ⅱ Upgrade laser facility显示文摘The Shen-Guang II Upgrade(SG-Ⅱ-U) laser facility consists of eight high-power nanosecond laser beams and one shortpulse picosecond petawatt laser. It is designed for the study of inertial confinement fusion(ICF), especially for conducting fast ignition(FI) research in China and other basic science experiments. To perform FI successfully with hohlraum targets containing a golden cone, the long-pulse beam and cylindrical hohlraum as well as the short-pulse beam and cone target alignment must satisfy tight specifications(30 and 20 μm rms for each case). To explore new ICF ignition targets with six laser entrance holes(LEHs), a rotation sensor was adapted to meet the requirements of a three-dimensional target and correct beam alignment. In this paper, the strategy for aligning the nanosecond beam based on target alignment sensor(TAS) is introduced and improved to meet requirements of the picosecond lasers and the new six LEHs hohlraum targets in the SG-II-U facility. The expected performance of the alignment system is presented, and the alignment error is also discussed. | Lei Ren Ping Shao Dongfeng Zhao Yang Zhou Zhijian Cai Neng Hua Zhaoyang Jiao Lan Xia Zhanfeng Qiao Rong Wu Lailin Ji Dong Liu Lingjie Ju Wei Pan Qiang Li Qiang Ye Mingying Sun Jianqiang Zhu Zunqi Lin | 2018 | High Power Laser Science and Engineering2018,6,1: | 2 |

| 4 | A comprehensive understanding of grain selection in spiral grain selector during directional solidification显示文摘It is of great importance to further investigate grain selection mechanism for the production of single crystal(SX) turbine blade because a single crystal with optimized crystal orientation will enhance service performance of the blade severely.In this paper,single crystals with different deviation angles,i.e.6°,12° and 29°, were obtained using directional solidification under the same casting conditions.It has been found that the grain selection in spiral selector is a coupling process where high order dendrites branch in the front side and primary dendrites disappear in the back side based on the metallographic analysis and electron back scatter diffraction(EBSD).Considering the development of liquid/solid interface by numerical simulation,a combination effect with space expansion,geometrical restriction and grain competition was proposed for spiral grain selection.The space expansion mechanism dominates the process as it provides growth space and driving force for high order dendrites advancing.Thereby,the smaller the take-off angle(θ) is,the larger space and the stronger driving force high order dendrites will get,and the higher efficient the selector will be. The competitive growth between the secondary dendrites plays more contribution than that of primary dendrites,i.e.grain with preferred secondary dendrites instead of preferred primary dendrites could outcompete during grain selection,and this is the reason why spiral grain selector cannot optimize the orientation of the primary dendrites.These findings provide experimental evidence for spatial control of SX growth,and benefit the sophistic casting fields such as turbine blade casting for improved yield. | Binqiang Wang Long Zeng Neng Ren Mingxu Xia Jianguo Li | 2022 | Journal of Materials Science & Technology2022,,7: | 1 |
| 5 | Design and performance of final optics assembly in SG-ⅡUpgrade laser facility显示文摘In high power laser facility for inertial confinement fusion research, final optics assembly(FOA) plays a critical role in the frequency conversion, beam focusing, color separation, beam sampling and debris shielding. The design and performance of FOA in SG-II Upgrade laser facility are mainly introduced here. Due to the limited space and short focal length, a coaxial aspheric wedged focus lens is designed and applied in the FOA configuration. Then the ghost image analysis,the focus characteristic analysis, the B integral control design and the optomechanical design are carried out in the FOA design phase. In order to ensure the FOA performance, two key technologies are developed including measurement and adjustment technique of the wedged focus lens and the stray light management technique based on ground glass.Experimental results show that the design specifications including laser fluence, frequency conversion efficiency and perforation efficiency of the focus spot have been achieved, which meet the requirements of physical experiments well. | Zhaoyang Jiao Ping Shao Dongfeng Zhao Rong Wu Lailin Ji Li Wang Lan Xia Dong Liu Yang Zhou Lingjie Ju Zhijian Cai Qiang Ye Zhanfeng Qiao Neng Hua Qiang Li Wei Pan Lei Ren Mingying Sun Jianqiang Zhu Zunqi Lin | 2018 | High Power Laser Science and Engineering2018,6,2: | 1 |

| 7 | Preterm neonate with a large congenital hemangioma on maxillofacial site causing thrombocytopenia and heart failure:A case report显示文摘BACKGROUND We report a rare case of a large congenital hemangioma(CH)in the maxillofacial region in a female neonate that caused thrombocytopenia and heart failure.With close multidisciplinary collaboration,the congenital hemangioma was successfully resected with good results.CASE SUMMARY The patient was delivered at gestational age of 36 wk by cesarean section due to cephalopelvic disproportion and lack of onset of labor(birth weight:2630 g).A right-sided facial tumor was detected in the fetus during routine antenatal ultrasound examination of the mother at 32 wk of gestation.Physical examination revealed a 7 cm×7 cm×3 cm hard,dull purple-colored mass on the right maxillofacial region.The mass was tense and had prominent surface telangiectasias.Laboratory investigations revealed reduced hemoglobin and platelet count,and increased activated partial thromboplastin time,prothrombin time,and thrombin time.International normalized ratio,fibrin degradation products,and D-Dimer levels were significantly increased.Thromboelastography showed increased alpha angle,mean amplitude,and the clot formation speed.Thyroid-stimulating hormone level was significantly elevated.The patient was administered prednisone,propranolol,euthyrox,vitamin K1,milrinone,and digoxin.After operation,cefepime was administered for anti-infection and propranolol was prescribed at discharge.CONCLUSION We report a rare case of CH in the right maxillofacial region causing thrombocytopenia and heart failure. | Neng Ren Chun-Shun Jin Xiao-Qi Zhao Wen-Hui Gao Yu-Xian Gao Yuan Wang Yun-Feng Zhang | 2022 | World Journal of Clinical Cases2022,10,17: | 0 |
| 8 | A review on prediction of casting defects in steel ingots:from macrosegregation to multi-defect model显示文摘Due to the nature of the solute redistribution,the reduction in the solidification rate with time in a square root relationship,and the multiphase melt flow during the solidification,casting defects such as macrosegregation,shrinkage cavity,and porosity will inevitably occur in the steel ingot and intensify with the increase in ingot size.These defects directly affect the performance of the final product and severely restrict the choice of subsequent thermal processing methods and process windows.Therefore,the solidification defects including macrosegregation,shrinkage/porosity,and inclusions encountered in the preparation of large steel ingots and their formation mechanisms were reviewed.The development progress and the latest development of the macrosegregation model for steel ingots were introduced in detail,especially the latest progress in the coupling prediction of macrosegregation and shrinkage as well as macrosegregation and inclusions.Some methods to reduce macrosegregation of ingots were discussed as well.Finally,a new casting method called layered casting was introduced in detail.This method can effectively improve the uniformity of the macrostructure and reduce the macrosegregation of the large ingots and therefore is a promising method for preparing large ingots with high homogeneity. | Jun Li Xiao-wei Xu Neng Ren Ming-xu Xia Jian-guo Li | 2022 | Journal of Iron and Steel Research(International)2022,29,12: | 0 |

| 12 | The novel SLC40A1(T419I)variant results in a loss-of-function phenotype and may provide insights into the mechanism of large granular lymphocytic leukemia and pure red cell aplasia显示文摘Variants in the solute carrier family 40 member 1(SLC40A1)gene are the molecular basis of ferroportin disease,which is an autosomal dominant hereditary hemochromatosis.Here,we present a patient with pure red cell aplasia(PRCA)and large granular lymphocytic leukemia(LGLL)associated with an extremely high levels of serum ferritin and iron overload syndrome.Whole exon sequencing revealed a novel heterozygous variant in SLC40A1(p.T419I),which was found in his daughter as well.A series of functional studies in vitro of the T419I variant in ferroportin were conducted and the results revealed a reduced capacity of iron export from cells without changes in protein localization and its sensitivity to hepcidin.Intracellular iron storage in mutated cells was significantly higher than that of wild-type.These findings suggest that the novel variant p.T419I can cause the classical form of ferroportin disease and an elevated intracellular iron level indicates a potential novel pathogenic mechanism underlying PRCA and LGLL. | Hongfei Wu Xiang Ren Meili Ge Peiyuan Dong Shichong Wang Huiming Yi Xingxin Li Jiali Huo Xuan Zheng Mengying Gao Jinbo Huang Jing Zhang Min Wang Peng Jin Neng Nie Yingqi Shao Yizhou Zheng | 2022 | Blood Science2022,4,1: | 0 |
