1Large aperture N31 neodymium phosphate laser glass for use in a high power laser facility显示文摘Large aperture Nd:phosphate laser glass is a key optical element for an inertial confinement fusion(ICF) facility. N31,one type of neodymium doped phosphate glasses, was developed for high peak power laser facility applications in China. The composition and main properties of N31 glass are given, together with those of LHG-8, LG-770, and KGSS-0180 Nd:phosphate laser glasses, from Hoya and Schott, and from Russia. The technologies of pot melting, continuous melting, and edge cladding of large size N31 phosphate laser glass are briefly described. The small signal gain profiles of N31 glass slabs from both pot melting and continuous melting at various values of the pumping energy of the xenon lamp are presented. N31 glass is characterized by a stimulated emission cross section of 3.8 × 10-20cm2 at 1053 nm,an absorption coefficient of 0.10–0.15% cm-1at laser wavelength, small residual stress around the interface between the cladding glass and the laser glass, optical homogeneity of ~2 × 10-6in a 400 mm aperture, and laser damage threshold larger than 42 J/cm2 for a 3 ns pulse width at 1064 nm wavelength.Lili Hu Shubin Chen Jingping Tang Biao Wang Tao Meng Wei Chen Lei Wen Junjiang Hu Shunguang Li Yongchun Xu Yasi Jiang Junzhou Zhang Zhonghong Jiang 2014High Power Laser Science and Engineering2014,2,1:8
2Comparative analysis between endometrial proteomes of pregnant and non-pregnant ewes during the peri-implantation period显示文摘Background:Early pregnancy failure has a profound impact on both human reproductive health and animal production.2/3 pregnancy failures occur during the peri-implantation period;however,the underlying mechanism(s)remains unclear.Well-organized modification of the endometrium to a receptive state is critical to establish pregnancy.Aberrant endometrial modification during implantation is thought to be largely responsible for early pregnancy loss.Result:In this study,using well-managed recipient ewes that received embryo transfer as model,we compared the endometrial proteome between pregnant and non-pregnant ewes during implantation period.After embryo transfer,recipients were assigned as pregnant or non-pregnant ewes according to the presence or absence of an elongated conceptus at Day 17 of pregnancy.By comparing the endometrial proteomic profiles between pregnant and non-pregnant ewes,we identified 94 and 257 differentially expressed proteins(DEPs) in the endometrial caruncular and intercaruncular areas,respectively.Functional analysis showed that the DEPs were mainly associated with immune response,nutrient transport and utilization,as well as proteasome-mediated proteolysis.Conclusion:These analysis imply that dysfunction of these biological processes or pathways of DEP in the endometrium is highly associated with early pregnancy loss.In addition,many proteins that are essential for the establishment of pregnancy showed dysregulation in the endometrium of non-pregnant ewes.These proteins,as potential candidates,may contribute to early pregnancy loss.Haichao Zhao Linlin Sui Kai Miao Lei An Dong Wang Zhuocheng Hou Rui Wang Min Guo Zhilong Wang Jiqiang Xu Zhonghong Wu Jianhui Tian 2015Journal of Animal Science and Biotechnology2015,6,3:8
3Selective removal of heavy metal ions in aqueous solutions by sulfide-selector intercalated layered double hydroxide adsorbent显示文摘Remaining largely under-appreciated, a majority of metal ion sorbents are limited in their target selectivity. In this work, a 3D sulfide intercalated NiFe-layered double hydroxide (NFL-S) hierarchical sorbent has been synthesized for selective heavy metal removal. The intercalation of sulfurated groups in the interlayer of the layered double hydroxide (LDH) nanosheets endows NFL-S as a selective heavy metal ion filter;the selectivity of NFL-S for heavy metals is in the order of Pb^2+> Cu^2+≥ Zn^2+> Cd^2+> Mn^2+, and NFL-S has high kd values for Pb2+(~10^6 mL/g) and Cu2+(~10^5 mL/g). Scanning electron microscopy. X-ray photoelectron spectroscopy and powder X-ray diffraction were used to analyze the composition of the as-prepared nanoadsorbent. The selective adsorption behavior was systematically studied using batch experiments, and the performance was evaluated through kinetic and isotherm studies. Moreover, the adsorption mechanism of heavy metals by NFL-S through surface complexation was also investigated, which shows great potential for water decontamination.Jing Wang Liang Zhang Tianshu Zhang Ting Du Tao Li Tianli Yue Zhonghong Li Jianlong Wang 2019Journal of Materials Science & Technology2019,35,9:5
4Study on Laser Welding of Al Composite显示文摘The effects of laser welding parameter on strength of welded joints were studied. The mechanism for loss of joint strength was analyzed. It was pointed out that an important factor affecting joint strength is the reaction between matrix and reinforced phase. On the basis of this, the concept of critical St activity a[si]min was proposed. Using appropriate welding parameters and Si activity, high quality laser welded joints in an aluminum matrix composite SiCw/6061Al can be Successfully obtained.Jitai NIU Zhonghong LAI MuZhen WANG Liming LIU and Lin WU National Key Laboratory of Advanced Welding Production Technology, Harbin institute of Technology, Harbin 150001, China 2001Journal of Materials Science & Technology2001,17,1:3
5Anal swab findings in an infant with COVID-19显示文摘Introduction: The transmission pathways of coronavirus disease 2019 (COVID-19) remain not completely clear. In this case study the test for the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in pharyngeal swab and anal swab were compared.Case presentation: A 3-month-old girl was admitted to our hospital with COVID-19. Her parents had both been diagnosed with COVID-19. The results of pharyngeal swab and anal swab of the little girl were recorded and compared during the course of the disease. The oropharyngeal specimen showed negative result for SARS-CoV-2 on the 14th day after onset of the illness. However, the anal swab was still positive for SARS-CoV-2 on the 28th day after the onset of the illness.Conclusion: The possibility of fecal-oral transmission of COVID-19 should be assessed. Personal hygiene during home quarantine merits considerable attention.Qihong Fan Yan Pan Qingcui Wu Shan Liu Xu Song Zhongguo Xie Yang Liu Liang Zhao Zhonghong Wang Yifei Zhang Zuchuang Wu Lei Guan Xiaolong Lv 2020Pediatric Investigation2020,4,1:3
6Phosphorylation of histone H3 on Ser10 by auto-phosphorylated PAK1 is not essential for chromatin condensation and meiotic progression in porcine oocytes显示文摘Background: The p21-activated kinase 1 (PAK1) is essential for mitosis and plays an important role in the regulation of microtubule assembly during oocyte meiotic maturation in mice; however, little is known about its role in porcine oocytes. Result: Total p21-activated kinase 1 (PAK1) and phosphorylated PAK1 at Thr423 (PAK1 Thr423 ) were consistently expressed in porcine oocytes from the germinal vesicle (GV) to the second metaphase (MII) stages, but phosphorylation of histone H3 at Ser10 (H3 Ser10 ) was only expressed after the GV stage. Immunofluorescence analysis revealed that PAK1 Thr423 and H3 Ser10 colocalized on chromosomes after the GV stage. Blocking of endogenous PAK1 Thr423 by injecting a specific antibody decreased the phosphorylation level of H3 Ser10 ; however, it had no impact on chromatin condensation, meiotic progression, cleavage rate of blastomeres or the rate of blastocyst formation. Conclusion: Phosphorylation of PAK1 Thr423 is a spontaneous activation process and the activated PAK1 Thr423 can promote the phosphorylation of H3 Ser10 ; however, this pathway is not required for meiotic maturation of porcine oocytes or early embryonic development.Bingyuan Wang Wei Ma Xiaoling Xu Chao Wang Yubo Zhu Na An Lei An Zhonghong Wu Jianhui Tian 2013Journal of Animal Science and Biotechnology2013,4,2:2

16Mechanisms of peroxynitrite-induced [Ca^(2+)]_i increase in single neuronal cell显示文摘The mechanism of peroxynitrite (ONOO -)induced [Ca 2+ ] i increase in single MN9D cell (Dopaminergic neuroblastoma cell line) was studied by using Fura2 microfluorometric technique. The results show that ONOO - caused a rapid increase of [Ca 2+ ] i when ONOO - was puffed to the cell. Removing Ca 2+ from the bath or using calcium channel antagonist (CdCl 2, Nifedipine) greatly inhibited the [Ca 2+ ] i increase induced by ONOO -, suggesting that the opening of LCa 2+ channel makes a great contribution to the [Ca 2+ ]\-i increase. The effect of sulfhydryl reductive agent (DTT) on ONOO -induced [Ca 2+ ]\-i increase suggests that ONOO -activating LCa 2+ channel is partly related to its oxidative speciality.YI Yong 1, CAI Dong 1, GAO Zhonghong 1, YANG Xiangliang 1, QU Anlian 1, XU Huibi 1* , WANG Xiaomin 2 and HAN Songping 3 1.

19M^(2)LC-Net: A Multi-Modal Multi-Disease Long-Tailed Classification Network for Real Clinical Scenes显示文摘Leveraging deep learning-based techniques to classify diseases has attracted extensive research interest in recent years.Nevertheless,most of the current studies only consider single-modal medical images,and the number of ophthalmic diseases that can be classified is relatively small.Moreover,imbalanced data distribution of different ophthalmic diseases is not taken into consideration,which limits the application of deep learning techniques in realistic clinical scenes.In this paper,we propose a Multimodal Multi-disease Long-tailed Classification Network(M^(2)LC-Net)in response to the challenges mentioned above.M^(2)LC-Net leverages ResNet18-CBAM to extract features from fundus images and Optical Coherence Tomography(OCT)images,respectively,and conduct feature fusion to classify 11 common ophthalmic diseases.Moreover,Class Activation Mapping(CAM)is employed to visualize each mode to improve interpretability of M^(2)LC-Net.We conduct comprehensive experiments on realistic dataset collected from a Grade III Level A ophthalmology hospital in China,including 34,396 images of 11 disease labels.Experimental results demonstrate effectiveness of our proposed model M^(2)LC-Net.Compared with the stateof-the-art,various performance metrics have been improved significantly.Specifically,Cohen’s kappa coefficient κ has been improved by 3.21%,which is a remarkable improvement.Zhonghong Ou Wenjun Chai Lifei Wang Ruru Zhang Jiawen He Meina Song Lifei Yuan Shengjuan Zhang Yanhui Wang Huan Li Xin Jia Rujian Huang 2021China Communications2021,18,9:0
