1Features and Formation Mechanism of Faults and Potash-forming Effect in the Lop Nur Salt Lake,Xinjiang,China显示文摘The Lop Nur Salt Lake, located in the eastern part of the Tarim Basin, Xinjiang, China, has become a playa in the Quaternary. Rhombic in shape, the Lop Nur depression is mainly controlled by the NE-striking and nearly N-S-striking sets of faults. Since 1995, a superlarge brine potash deposit with potash resources of 2.50×108 t has been found in the Luobei subbasin in the northeastern part of the Lop Nur. We intensively studied the features and formation mechanism of faults inside the Lop Nur through satellite images, geomorphologic survey and continuous conductivity imaging and found seven subparallel graben faults formed under the action of nearly N 10o E principal compressional stress during deposition of the Lop Nur Salt Lake. These faults are up to >60 km long and 1–4 km wide and may extend downward for 1000 m or more. It is just under the action of these tensional faults that potash subbasins formed. The largest subbasin is the Luobei subbasin and the smaller ones are the Luoxi hollow, Erbei hollow and Tienan hollow. Investigation also indicates that the graben faults in the Lop Nur not only control the origin of the potash subbasins, but they themselves are also good brine reservoir structures, in which abundant potash-rich brines are stored. Therefore, The faults had played an important role in the potash formation of the Lop Nur.LIU Chenglin WANG Mili JIAO Pengcheng LI Shude CHEN Yongzhi 2006Acta Geologica Sinica(English Edition)2006,80,6:33
2Improving Joint Morphologies and Tensile Strength of Al/Mg Dissimilar Alloys Friction Stir Lap Welding by Changing Zn Interlayer Thickness显示文摘The pure Zn foils with different thicknesses(0.02, 0.05, 0.1, 0.2 and 0.3 mm) were selected as interlayers to improve the quality of friction stir lap welding joint of 7075-T6 Al and AZ31 B Mg dissimilar alloys. The effects of the interlayer thickness on joint formation, microstructure and tensile strength were analyzed. The results displayed that the maximum length of the boundary between stir zone(SZ) and thermo-mechanically affected zone in lower plate was obtained by the addition of the Zn interlayer with 0.05 mm thickness. The Mg–Zn intermetallic compounds(IMCs) were discontinuously distributed in the SZ, replacing the continuous Al–Mg IMCs. The size of Mg–Zn IMCs increased with the increase in the thickness of the Zn interlayer. The maximum tensile shear strength of 276 N mm-1 was obtained by the addition of 0.05 mm Zn foil, which increased by 45.6% of that of the joint without the Zn foil addition.Jinglin Liu Shiyu Niu Rong Ren Shude Ji Lei Wang Zan Lv 2019Acta Metallurgica Sinica(English Letters)2019,32,11:5
3Changes of visceral properties and digestive enzymes in the herbivorous marine teleost Siganus canaliculatus fed on different diets显示文摘The rabbitfish Siganus canaliculatus is one of the few cultured herbivorous marine teleosts. To better understand the digestive physiology of this fish and provide data for designing formulated feed using macroalgae as an ingredient, the changes of visceral properties and digestive enzyme activities were investigated after the juveniles were fed on different types of food including raw fish(RF), formulated diet(FD) or macroalgae Enteromorpha prolifra(EP) and Gracilaria lemaneiformis(GL) for eight weeks. The results showed that the hepatosomatic and viscerosomatic indices in the RF and FD groups, as well as the relative intestine length(RIL) in the EP and GL groups, were significantly higher than those in other groups. Additionally, differences in the histological structure of the liver and anterior intestine were also observed among different dietary groups. The hepatic nuclei were displaced to the periphery by lipid inclusions in fish fed RF. The highest levels of mucosal folds were found in the anterior intestines of fish fed macroalgae. Digestive enzyme activity profiles showed obvious fluctuations in the first three weeks, and then leveled off in the following weeks. The levels of protease, lipase and α-amylase in the alimentary tract showed changes related to the levels of dietary protein, lipid and carbohydrate, respectively.Although macroalgae significantly inhibited the activity of protease in the stomach, it increased RIL and the number of mucosal folds in the anterior intestine so as to compensate for the influences on protease activities in the stomach. This study suggests that the digestive tract of rabbitfish can well adapt to different diets, and needs about three weeks to physiologically acclimatize to the nutritional status, thus implying that rabbitfish are somewhat omnivorous.XIE Dizhi XU Shude WU Qingyang CHEN Fang WANG Shuqi YOU Cuihong LI Yuanyou 2018Acta Oceanologica Sinica2018,37,2:3
4A functionalized separator enables dendrite-free Zn anode via metal-polydopamine coordination chemistry显示文摘Designing a multifunctional separator with abundant ion migration paths is crucial for tuning the ion transport in rocking-chair-type batteries.Herein,a polydopamine-functionalized PVDF(PVDF@PDA)nanofibrous membrane is designed to serve as a separator for aqueous zinc-ion batteries(AZIBs).The functional groups(OH and NH)in PDA facilitate the formation of Zn O and Zn N coordination bonds with Zn ions,homogenizing the Zn-ion flux and thus enabling dendrite-free Zn deposition.Moreover,the PVDF@PDA separator effectively inhibits the shuttling of V-species through the formation of V-O coordination bonds.As a result,the Zn/NH_(4)V_(4)O_(10) battery with the PVDF@PDA separator exhibits enhanced cycling stability(92.3%after 1000 cycles at 5 A g^(-1))and rate capability compared to that using a glass fiber separator.This work provides a new avenue to design functionalized separators for high-performance AZIBs.Yanfen Liu Shude Liu Xuesong Xie Zhicheng Li Pinji Wang Bingan Lu Shuquan Liang Yan Tang Jiang Zhou 2023InfoMat2023,5,3:2

8Immunomodulatory effects and mechanisms of distraction osteogenesis显示文摘Distraction osteogenesis(DO) is widely used for bone tissue engineering technology. Immune regulations play important roles in the process of DO like other bone regeneration mechanisms. Compared with others, the immune regulation processes of DO have their distinct features. In this review, we summarized the immune-related events including changes in and effects of immune cells, immune-related cytokines, and signaling pathways at different periods in the process of DO. We aim to elucidated our understanding and unknowns about the immunomodulatory role of DO. The goal of this is to use the known knowledge to further modify existing methods of DO, and to develop novel DO strategies in our unknown areas through more detailed studies of the work we have done.Shude Yang Ning Wang Yutong Ma Shuaichen Guo Shu Guo Hongchen Sun 2022International Journal of Oral Science2022,14,1:1
9Stabilizing zinc anode using zeolite imidazole framework functionalized separator for durable aqueous zinc-ion batteries显示文摘Aqueous zinc-ion batteries(AZIBs) hold great promise as a viable alternative to lithium-ion batteries owing to their high energy density and environmental friendliness.However,AZIBs are consistently plagued by the formation of zinc dendrites and concurrent side reactions,which significantly diminish their overall service life,In this study,the glass fiber separator(GF) is modified using zeolite imidazole salt framework-8(ZIF-8),enabling the development of efficient AZIBs.ZIF-8,which is abundant in nitrogen content,efficiently regulates the desolvation of [Zn(H_(2)O)_(6)]^(2+) to inhibit hydrogen production.Moreover,it possesses abundant nanochannels that facilitate the uniform deposition of Zn~(2+) via a localized action,thereby hindering the formation of dendrites.The insulating properties of ZIF-8 help prevent Zn^(2+) and water from trapping electron reduction at the layer surface,which reduces corrosion of the zinc anode.Consequently,ZIF-8-GF achieves the even transport of Zn^(2+) and regulates the homogeneous deposition along the Zn(002) crystal surface,thus significantly enhancing the electrochemical performance of the AZIBs,In particular,the Zn|Zn symmetric cell with the ZIF-8-GF separator delivers a stable cycle life at0.5 mA cm^(-2) of 2300 h.The Zn|ZIF-8-GF|MnO_(2) cell exhibits reduced voltage polarization while maintaining a capacity retention rate(93.4%) after 1200 cycles at 1.2 A g^(-1) The unique design of the modified diaphragm provides a new approach to realizing high-performance AZIBs.Weisong Zhang Xinyan Zhu Ling Kang Ziyu Peng Jing Zhu Liang Pan Lei Dai Shude Liu Ling Wang Yongguang Liu Zhangxing He 2024Journal of Energy Chemistry2024,90,3:0
10Magnesium alloys for orthopedic applications:A review on the mechanisms driving bone healing显示文摘Magnesium(Mg) alloys have attracted a wealth of attention in orthopedic fields for their superior mechanical properties, degradability,and excellent biocompatibility. Consistently, to resolve the issues on rapid degradation, more studies are dedicated to the researches on the composition design, preparation and processing, surface modification, the degradation modes of Mg alloys. Nevertheless, the mechanisms by which Mg alloys promote bone healing remain elusive. This review gives an account of specific mechanisms on Mg alloys promoting bone healing from four aspects, immunomodulatory, angiogenesis, osteogenesis and regulation of osteoclast function. We highlight the regulation of Mg alloys on the functional status and interactions of numerous cells that are involved in bone healing, including immune cells, osteogenicrelated cells, osteoclasts, endothelial cells(ECs), nerve cells, etc., and summarize the signaling pathways involved, with the aim to provide the basis and support on future investigation on mechanisms on Mg alloys driving bone regeneration. More importantly, it provides a rationale and a general new basis for the application of Mg alloys in orthopedic fields.Ning Wang Shude Yang Huixin Shi Yiping Song Hui Sun Qiang Wang Lili Tan Shu Guo 2022Journal of Magnesium and Alloys2022,10,12:0
11A study on the learning curve for a new radioactive seed template retainer assisted by CT-guided radioactive seed implantation for advanced non-small cell lung cancer显示文摘Objective:To explore the application of a new radioactive seed template retainer in the learning curve of CTguided 125I seed brachytherapy(CTISBT)for advanced non-small cell lung cancer(NSCLC).Methods:This study retrospectively analyzed the medical records of 60 patients who underwent CTISBT for advanced NSCLC by a single physician between January 2018 and December 2019.The data were sorted in order of admission and divided into three groups according to the order of surgery,group A(cases 1–20),group B(cases 21–40),and group C(cases 41–60).All patients underwent preoperative planning and postoperative dosimetry verification,and the operation time,intraoperative CT scans,postoperative hospital stay,and postoperative complications were compared among the three groups.The quality of life(QOL)score and tumor volume were compared before and 2 months after surgery.Results:There were no statistically significant differences among the three groups in QOL scores,tumor volume,and tumor site before CTISBT assisted by the new radioactive seed template retainer.However,the surgical time differed significantly between the three groups(P<0.01).The operation time was longer in group A than that in groups B and C(P<0.01).There was no significant difference between groups B and C.There were no significant differences in the number of CT scans among the three groups and the length of postoperative hospital stay.The follow-up QOL and tumor volume were significantly reduced at 2 months after surgery compared with those before surgery(P<0.01).Conclusions:The short-term efficacy of the new radioactive seed template retainer-assisted CTISBT was definitive for advanced NSCLC.After the physician had accumulated experience with 20 cases of a new type of radioactive seed template retainer-assisted CTISBT surgery,the follow-up operation time was significantly shortened and the learning curve entered the plateau stage.Xiaodong Huo Huixing Wang Bin Huo Lei Wang Shude Chai Junjie Wang Haitao Wang 2022Radiation Medicine and Protection2022,3,1:0
12Decoration of CdMoO_(4) micron polyhedron with Pt nanoparticle and their enhanced photocatalytic performance in N_(2) fixation and water purification显示文摘This study aimed to prepare and apply a novel Pt/CdMoO_(4) composite photocatalyst for photocatalytic N2 fixation and tetracycline degradation. The Pt/CdMoO_(4) composite was subjected to comprehensive investigation on the morphology, structure, optical properties, and photoelectric chemical properties. The results demonstrate the dispersion of Pt nanoparticles on the CdMoO_(4) surface. Close contact between CdMoO_(4) and Pt was observed, resulting in the formation of a heterojunction structure at their contact region. Density functional theory calculation and Mott-Schottky analysis revealed that Pt possesses a higher work function value than CdMoO_(4), resulting in electron drift from CdMoO_(4) to Pt and the formation of a Schottky barrier. The presence of this barrier increases the separation efficiency of electron-hole pairs, thereby improving the performance of the Pt/CdMoO_(4) composite in photocatalysis. When exposed to simulated sunlight, the optimal Pt/CdMoO_(4) catalyst displayed a photocatalytic nitrogen fixation rate of 443.7 μmol·L‒^(1)·g‒^(1)·h‒^(1), which is 3.2 times higher than that of pure CdMoO_(4). In addition, the composite also exhibited excellent performance in tetracycline degradation, with hole and superoxide species identified as the primary reactive species. These findings offer practical insights into designing and synthesizing efficient photocatalysts for photocatalytic nitrogen fixation and antibiotics removal.Xujie Ren Junfeng Wang Shude Yuan Chunran Zhao Lin Yue Zhihao Zeng Yiming He 2023Frontiers of Chemical Science and Engineering2023,17,12:0
13DNA barcoding of fishes from Zhoushan coastal waters using mitochondrial COI and 12S rRNA genes显示文摘Accurate species identification is a key component of biodiversity research.DNA barcoding is an effective molecular method used for fish species identification.We aimed to study the DNA barcoding of fish in Zhoushan coastal waters,explore the differences and applicability of two gene fragments(12S rRNA and COI)of DNA barcoding in fish species identification,and established a comprehensive fish barcoding reference database.Two hundred and eighty-seven captured fish samples from Zhoushan coastal waters were identified using morphological characteristics and DNA barcoding.A total of 26412S rRNA sequences(belonging to eight orders,31 families,55 genera,and 66 species)and 188 COI sequences(belonging to seven orders,30 families,48 genera,and 58 species)were obtained.The lengths of the 12S rRNA sequences ranged from 165 to 178 bp,and the guanine-cytosine(GC)content was 45.37%.The average 12S rRNA interspecific and intraspecific genetic distances(K2P)were 0.10%and 26.66%,respectively.The length of the COI sequence ranged 574–655 bp,and the content of GC was 45.97%.The average 12S rRNA interspecific and intraspecific genetic distances(K2P)were 0.16%and 27.45%,respectively.The minimum interspecific genetic distances of 12S rRNA and COI(1.23%and 1.86%)were both greater than their maximum intraspecific genetic distances(2.42%and 8.66%).Three molecular analyses(NJ tree,ABGD,and GMYC)were performed to accurately identify and delineate species.Clustering errors occurred when the 12S rRNA sequences were delimited using the NJ tree method,and the delimitation results of ABGD and GMYC are consistent with the final species identification results.Our results demonstrate that DNA barcoding based on 12S rRNA and COI can be used as an effective tool for fish species identification,and 12S rRNA has good application prospects in the environmental DNA(eDNA)metabarcoding of marine fish.Yehui WANG Na SONG Shude LIU Zhi CHEN Anle XU Tianxiang GAO 2023Journal of Oceanology and Limnology2023,41,5:0
14Adjuvant tamoxifen switched to exemestane treatment in postmenopausal women with estrogen receptor-positive early breast cancer:A pragmatic,multicenter,and prospective clinical trial in China显示文摘Objective:This post-approval safety study assessed the efficacy and safety of exemestane after 2-3 years of tamoxifen treatment among postmenopausal women with estrogen receptor-positive(ER+)early breast cancer in China.Methods:Enrolled patients had received 2-3 years of tamoxifen and were then switched to exemestane for completion of 5 consecutive years of adjuvant endocrine therapy.The primary endpoint was the time from enrollment to the first occurrence of locoregional/distant recurrence of the primary breast cancer,appearance of a second primary or contralateral breast cancer,or death due to any cause.Other endpoints included the proportion of patients experiencing each event,incidence rate per annum,relationships between human epidermal growth factor receptor 2 status and time to event,and relationship between disease history variables and time to event.Results:Overall,558 patients were included in the full analysis set:397(71.1%)completed the study,20experienced an event,and 141 discontinued[47 owing to an adverse event(AE);37 no longer willing to participate].Median duration of treatment was 29.5(range,0.1-57.7)months.Median time to event was not reached.Eventfree survival probability at 36 months was 91.4%(95%CI,87.7%-95.1%).The event incidence over the total exposure time of exemestane therapy was 3.5 events/100 person-years(20/565).Multivariate analysis showed an association between tumor,lymph node,and metastasis stage at initial diagnosis and time to event[hazard ratio:1.532(95%CI,1.129-2.080);P=0.006].Most AEs were grade 1 or 2 in severity,with arthralgia(7.7%)being the most common treatment-related AE.Conclusions:This study supports the efficacy and safety of exemestane in postmenopausal Chinese women with ER+breast cancer previously treated with adjuvant tamoxifen for 2-3 years.No new safety signals were identified in the Chinese population.Binghe Xu Huiping Li Zefei Jiang Lin Gu Jinhai Tang Hui Xie Yueyin Pan Yunjiang Liu Shude Cui Xiaojia Wang Li Cai Yiqiong Zhang Huadong Zhao Zhimin Shao 2022Chinese Journal of Cancer Research2022,34,6:0
15An Improved JSO and Its Application in Spreader Optimization of Large Span Corridor Bridge显示文摘In this paper,given the shortcomings of jellyfish search algorithmwith low search ability in the early stage and easy to fall into local optimal solution,this paper introduces adaptive weight function and elite strategy,improving the global search scope in the early stage and the ability to refine the local development in the later stage.In the numerical study,the benchmark problem of dimensional optimization with a 10-bar truss structure and simultaneous dimensional shape optimization with a 15-bar truss structure is adopted,and the corresponding penalty method is used for constraint treatment.The test results show that the improved jellyfish search algorithm can provide better truss sections as well as weights.Because when the steel main truss of the large-span covered bridge is lifted,the site is limited and the large lifting equipment cannot enter the site,and the original structure does not meet the problem of stress concentration and large deformation of the bolt group,so the spreader is used to lift,and the improved jellyfish search algorithm is introduced into the design optimization of the spreader.The results show that the improved jellyfish algorithm can efficiently and accurately find out the optimal shape and weight of the spreader,and throughMidas Civil simulation,the spreader used canmeet the requirements of weight and safety.Shude Fu Xinye Wu Wenjie Wang Yixin Hu Zhengke Li Feng Jiang 2024Computer Modeling in Engineering & Sciences2024,138,3:0
16Thermo-Mechanical Analysis of the Sealing Performance of a Diesel-Engine Cylinder Gasket显示文摘Taking the combustor composite structure of a high-strength diesel engine as the main research object,dedicated tests have been conducted to verify the accuracy of three distinct cylinder gasket pressure simulation models.Using the measured cylinder gasket compression rebound curve,a gasket unit has been designed and manufactured.For this unit,the influence of the bolt pretension,cylinder body and cylinder head material on gasket sealing pressure has been investigated systematically in conditions of thermo-mechanical coupling.The results show that the bolt pretension force is one of the most important factors affecting the cylinder gasket sealing pressure.The change of the body material has little effect on this pressure.The cylinder gasket seal pressure decreases progressively with the reduction of the elastic module of the cylinder head material.Xulan Wang Zezhong Chen Changzhen Liu Wei Ren Bo Wu Shude Ji Xiaofei Chen Shijie Wen Yonggang Hao 2021Fluid Dynamics & Materials Processing2021,17,4:0

19Stellar Dynamical Modeling—Counting Conserved Quantities显示文摘Knowing the conserved quantities that a galaxy’s stellar orbits conform to is important in helping us understand the stellar distribution and structures within the galaxy.Isolating integrals of motion and resonances are particularly important,non-isolating integrals less so.We compare the behavior and results of two methods for counting the number of conserved quantities,one based on the correlation integral approach and the other a more recent method using machine learning.Both methods use stellar orbit trajectories in phase space as their only input,and we create such trajectories from theoretical spherical,axisymmetric,and triaxial model galaxies.The orbits have known isolating integrals and resonances.We find that neither method is fully effective in recovering the numbers of these quantities,nor in determining the number of non-isolating integrals.From a computer performance perspective,we find the correlation integral approach to be the faster.Determining the algebraic formulae of(multiple)conserved quantities from the trajectories has not been possible due to the lack of an appropriate symbolic regression capability.Notwithstanding the shortcomings we have noted,it may be that the methods are usable as part of a trajectory analysis tool kit.Richard J.Long Shude Mao Yougang Wang 2023Research in Astronomy and Astrophysics2023,23,5:0
