System scan of the multiplicity correlation between forward and backward rapidities in relativistic heavy-ion collisions using a multi-phase transport model

A systematic study on forward-backward(FB) multiplicity correlations from large systems to small ones through a multi-phase transport model(AMPT) has been performed and the phenomenon that correlation strength increases with centrality can be explained by taking the distribution of events as the superposition of a series of Gaussian distributions. It is also found that correlations in the η-φ plane can imply the shape of the event. Furthermore,long-range correlations originate from the fluctuations associated with the source information. FB correlations allow us to decouple long-range correlations from short-range correlations, and may provide a chance to investigate the aclustering structure in initial colliding light nuclei as well. It seems the tetrahedron ~(16)O+~(16)O collision gives a more uniform and symmetrical fireball, that emits the final particles more isotropically or independently in the longitudinal direction, indicating that the forward-backward multiplicity correlation could be used to identify the pattern of aclustered ~(16)O in future experiments.
Nucleolar histone deacetylases HDT1,HDT2,and HDT3 regulate plant reproductive development

Nucleolus is a membrane-less organelle where ribosomes are assembled,and ribosomal RNAs (rRNAs) transcribed and processed.The assembled ribosomes composed of ribosomal proteins and rRNAs synthesize proteins for cell survival.In plants,the loss of nucleolar ribosomal proteins often causes gametophytically or embryonically lethality.The amount of rRNAs are under stringent regulation according to demand and partially switched off by epigenetic modifications.However,the molecular mechanism for the selective activation or silencing is still unclear,and the transcriptional coordination of rRNAs and ribosomal proteins is also unknown.Here,we report the critical role of three Arabidopsis nucleolar proteins HDT1,HDT2,and HDT3 in fertility and transcription of rDNAs and rRNA processing-related genes through histone acetylation.This study highlights the important roles of transcriptional repression of ribosome biogenesisrelated genes for plant reproductive development.
Hierarchically porous Beta/SBA-16 with different silica-alumina ratios and the hydrodesulfurization performances of DBT and 4,6-DMDBT

Hierarchically porous Beta/SBA-16(BS)composite materials, combining the characteristics of the acidity from the Beta zeolite and the three-dimensional structure from SBA-16, were synthesized successfully through a two-step in-situ assembly hydrothermal crystallization method. A series of NiMo catalysts supported on BS with different silica-alumina ratios were prepared. The supports and the corresponding catalysts were characterized by XRD, N_2 physisorption, ~(27)Al MAS NMR, TEM, pyridine-FTIR, Raman, XPS and HRTEM. The activities of series catalysts were evaluated by the hydrodesulfurization(HDS)performances of dibenzothiophene(DBT)and 4,6-dimethyldibenzothiophene(4,6-DMDBT). It was found that the Beta crystallites were embedded into SBA-16 through silanols accompanied by dealumination on the T3-T9 sites of Beta crystallites. NiMo/BS-3 with a silica-alumina ratio of 100 exhibited the highest DBT and 4,6-DMDBT HDS activities at the WHSV value of 10 h~(-1), with the conversions of 95.9% and 86.9% respectively, due to the synergistic effects of the suitable specific surface areas, the relatively large pore size, appropriate acidity, the relatively high sulfidation degree, moderate dispersity and good stacking degree of MoS_2 active phases.
Efficient aerobic oxidative desulfurization via three-dimensional ordered macroporous tungsten-titanium oxides

A series of three-dimensional ordered macroporous(3DOM)W-TiO_2 catalysts have been prepared through a facile colloidal crystal template method. The prepared materials characterized in detail exhibited enhanced catalytic activity in aerobic oxidative desulfurization process. The experimental results indicated that the as-prepared materials possessed excellent 3DOM structure, which is beneficial for the catalytic activity. The sample 3DOMW-TiO_2-20 exhibited the highest activity in ODS process, and the sulfur removal can reach 98% in 6 h. Furthermore, the oxidative product was also analyzed in the reaction process.
Evaluation of natural gas hydrate resources in the South China Sea using a new genetic analogy method

Natural gas hydrate(NGH)has attracted much attention as a new alternative energy globally. However,evaluations of global NGH resources in the past few decades have casted a decreasing trend, where the estimate as of today is less than one ten-thousandth of the estimate forty years ago. The NGH researches in China started relatively late, but achievements have been made in the South China Sea(SCS)in the past two decades. Thirty-five studies had been carried out to evaluate NGH resource, and results showed a flat trend, ranging from 60 to 90 billion tons of oil equivalent, which was 2-3 times of the evaluation results of technical recoverable oil and gas resources in the SCS. The big difference is that the previous 35 group of NGH resource evaluations for the SCS only refers to the prospective gas resource with low grade level and high uncertainty, which cannot be used to guide exploration or researches on development strategies. Based on the analogy with the genetic mechanism of conventional oil and gas resources, this study adopts the newly proposed genetic method and geological analogy method to evaluate the NGH resource. Results show that the conventional oil and gas resources are 346.29 ×10~8 t, the volume of NGH and free dynamic field are 25.19 ×10~4 km~3 and(2.05-2.48)×10~6 km~3, and the total amount of in-situ NGH resources in the SCS is about(4.47-6.02)×10~(12) m~3. It is considered that the resource of hydrate should not exceed that of conventional oil and gas, so it is 30 times lower than the previous estimate. This study provides a more reliable geological basis for further NGH exploration and development.
Evaluation of natural gas hydrate resources in the South China Sea by combining volumetric and trend-analysis methods

Natural gas hydrate(NGH), considered as a type of premium energy alternative to conventional hydrocarbons,has been broadly studied. The estimate of the total NGH resources in the world has decreased by more than 90% since the first evaluation in 1973. Geographic and geophysical conditions of the South China Sea(SCS)are favorable for the formation of NGH, which has been proved by drilling results up to date. The recoverability of the NGH in the SCS has been confirmed by the production tests using both vertical and horizontal wells. Since 2001, 35 estimates of NGH resources in the SCS have been made, with relatively stable results varying between 600 and 900 ×10~9 ton oil equivalent. In these estimations, the volumetric method was commonly adopted, but the geological conditions, the migration-accumulation mechanisms of NGH, and the practical recoverability were not considered. These estimates cannot be regarded as evaluated resources according to the international resource evaluation standards, but are at most about prospective gas content of NGH, thus inefficient for guiding explorations and developments. To solve these problems, this study divides the past NGH surveys in the SCS into seven stages, acquires key geological parameters of every stage based on previous studies and analogy with other areas, evaluates the NGH resources of these seven stages by using the volumetric method, then adopts a new trend-analysis method to simulate the downward trend of these estimates,and finally predicts the NGH resources in the SCS at 2025 and 2030. The downward trend is because of the continuous improvement of NGH understanding over time, which is consistent with the trend of global NGH estimates. At the present stage(from 2019 to 2021), the average technically recoverable resource(ATRR)is 7.0 ×10~(12) m~3, and the estimates of 2025 and 2030 ATRR are 6.46 ×10~(12) m~3 and 4.01 ×10~(12) m~3 respectively, with a difference of less than 40%. Therefore, it can be inferred that the ATRR of NGH in the SCS is between 4.0 and 6.5 ×10~(12) m~3, with an average of 5.25 ×10~(12) m~3.
Cancer statistics in China and United States,2022:profiles,trends,and determinants

Background:The cancer burden in the United States of America (USA) has decreased gradually.However,China is experiencing a transition in its cancer profiles,with greater incidence of cancers that were previously more common in the USA.This study compared the latest cancer profiles,trends,and determinants between China and USA.Methods:This was a comparative study using open-source data.Cancer cases and deaths in 2022 were calculated using cancer estimates from GLOBOCAN 2020 and population estimates from the United Nations.Trends in cancer incidence and mortality rates in the USA used data from the Surveillance,Epidemiology,and End Results program and National Center for Health Statistics.Chinese data were obtained from cancer registry reports.Data from the Global Burden of Disease 2019 and a decomposition method were used to express cancer deaths as the product of four determinant factors.Results:In 2022,there will be approximately 4,820,000 and 2,370,000 new cancer cases,and 3,210,000 and 640,000 cancer deaths in China and the USA,respectively.The most common cancers are lung cancer in China and breast cancer in the USA,and lung cancer is the leading cause of cancer death in both.Age-standardized incidence and mortality rates for lung cancer and colorectal cancer in the USA have decreased significantly recently,but rates of liver cancer have increased slightly.Rates of stomach,liver,and esophageal cancer decreased gradually in China,but rates have increased for colorectal cancer in the whole population,prostate cancer in men,and other seven cancer types in women.Increases in adult population size and population aging were major determinants for incremental cancer deaths,and case-fatality rates contributed to reduced cancer deaths in both countries.Conclusions:The decreasing cancer burden in liver,stomach,and esophagus,and increasing burden in lung,colorectum,breast,and prostate,mean that cancer profiles in China and the USA are converging.Population aging is a growing determinant of incremental cancer burden.Progress in cancer prevention and care in the USA,and measures to actively respond to population aging,may help China to reduce the cancer burden.
Mechanistic insights into homogeneous electrocatalytic reaction for energy storage using finite element simulation

The application of homogeneous electrocatalytic reactions in energy storage and conversion has driven surging interests of researchers in exploring the reaction mechanisms of molecular catalysts. In this paper, homogeneous electrocatalytic reaction between hydroxymethylferrocene(HMF) and L-cysteine is intensively investigated by cyclic voltammetry and square wave voltammetry for which, the secondorder rate constant(k_(ec)) of the chemical reaction between HMF+ and L-cysteine is determined via a 1D homogeneous electrocatalytic reaction model based on finite element simulation. The corresponding k_(ec)(1.1(mol·m~(-3))~(-1)·s~(-1)) is further verified by linear sweep voltammograms under the same model. Square wave voltammetry parameters including potential frequency(f), increment(Estep) and amplitude(ESW) have been comprehensively investigated in terms of the voltammetric waveform transition of homogeneous electrocatalytic reaction. Specifically, the effect of potential frequency and increment is in accordance with the potential scan rate in cyclic voltammetry and the increase of pulsed potential amplitude results in a conspicuous split oxidative peaks phenomenon. Moreover, the proposed methodology of k_(ec) prediction is examined by hydroxyethylferrocene(HEF) and L-cysteine. The present work facilitates the understanding of homogeneous electrocatalytic reaction for energy storage purpose, especially in terms of electrochemical kinetics extraction and flow battery design.
Simultaneous degradation of RhB and reduction of Cr(VI) by MIL-53(Fe)/Polyaniline(PANI) with the mediation of organic acid

MIL-53(Fe)/polyaniline(PANI) composite was prepared by in situ depositing PANI on the surface of MIL- 53(Fe) and their catalytic performances on the simultaneous removal of RhB and Cr(VI) were investigated. The elimination efficiency of both RhB and Cr(VI) reached more than 98% under pH = 2 where hydrochloric acid and citric acid were used to adjust the pH. The results indicated that MIL-53(Fe)/ PANI revealed an obvious pH response to the degradation of RhB, while citric acid promoted the Cr(VI) photoreduction. UV–Vis spectra, EIS, and photocurrent response experiments showed that MIL-53(Fe)/ PANI had a better light response and carrier migration ability than MIL-53(Fe). The transient absorption spectra also exhibited that the lifetimes of photo-generated carriers were prolonged after the conductive polymer deposition on the MIL-53(Fe) surface. Scavenger experiments demonstrated that the main active species were ·O_2~- and ·OH. Combined with activity evaluation results, and the possible photocatalytic mechanism of MIL-53(Fe)/PANI on RhB oxidation and Cr(VI) reduction was proposed. The addition of conductive polymer can effectively improve the light response of the catalyst under acidic conditions, and meanwhile citric acid also provided a new mediation for the synergistic degradation of multiple pollutants. Good activity and stability of the catalysts made the scale-up purification of acid water feasible under UV–Vis light.
Designed synthesis of porous carbons for the separation of light hydrocarbons

The separation of light hydrocarbon mixtures(C1–C3) generated from petrochemical industry is vital and challenging process for obtaining valuable pure chemical feedstocks. In comparison to the energy intensive conventional separation technologies(cryogenic distillation, absorption and hydrogenation), the adsorptive separation is considered as a low energy cost and high efficiency process. Porous carbons have been demonstrated as excellent adsorbents for the separation of light hydrocarbons, owing to their designable structure and tailorable properties. This review summarizes the recent advances of using porous carbons as adsorbents for the separation of light hydrocarbons, including methane/nitrogen, methane/ alkane, methane/carbon dioxide, ethylene/ethane and propylene/propane. We discuss the separation mechanisms and highlight the material features including pore structure, surface chemistry and target molecular properties that determine the separation performance. Furthermore, the challenges and development direction associated with carbonaceous adsorbents for light hydrocarbon separation are discussed, meanwhile the guidelines for the design of porous carbons are proposed.
Catalytic adsorptive desulfurization of mercaptan, sulfide and disulfide using bifunctional Ti-based adsorbent for ultra-clean oil

Ultra-deep desulfurization of transformer oil is of great demand among power industry. In this work, the effective and deep removal of various types of organosulfurs, including mercaptan, sulfide and disulfide via catalytic adsorptive desulfurization(CADS) using bifunctional Ti-based adsorbent is reported. Compared to adsorptive desulfurization(ADS), dramatically improvement of the organosulfur uptakes were achieved under CADS process. The equilibrium adsorption capacity at 5 lg·g~(-1) S reached up to 15.7, 33.4, 11.6 and 11.9 mg·g~(-1) for propyl mercaptan(n-PM), dimethyl sulfide(DMS), di-t-butyl disulfide(DTBDS) and dibenzyl disulfide(DBDS), which was 262, 477, 97 and 128 times to that of ADS process, respectively, and was the highest among the reported desulfurization adsorbents. Moreover, it achieved superior breakthrough capacity of 2050, 530 and 210 ml F·(g A)~(-1) at the breakthrough S concentration of 1 lg·g~(-1) of the commercial transformer oil S containing 10, 50 and 150 lg·g~(-1), respectively. The effectiveness of CADS is associated to the transformation of sulfur species to higher polar sulfonic species with the assistance of mild oxidant, which can be readily captured by silanol groups on SiO_2 through Hbonding interaction. The excellent recyclability of the adsorbent can be realized through solvent washing or oxidative air treatment. This work provides an effective and economic approach for the elimination of trace amount of mercaptan, sulfide and disulfide from transformer oil.
A pillared-layer metal–organic framework for efficient separation of C_3H_8/C_2H_6/CH_4 in natural gas

Metal-organic frameworks(MOFs) have great potentials as adsorbents for natural gas purification. However, the trade-off between selectivity and adsorption capacity remains a challenge. Herein, we report a pillared-layer metal-organic framework Ni(HBTC)(bipy) for efficiently separating the C_3H_8/ C_2H_6/CH_4 mixture. The experimental results show that the adsorption capacity of C_3H_8 and C_2H_6 on Ni(HBTC)(bipy) are as high as 6.18 and 5.85 mmol·g~(-1), while only 0.93 mmol·g~(-1) for CH_4 at 298 K and 100 kPa. Especially, the adsorption capacity of C_3H_8 at 5 kPa can reach an unprecedented 4.52 mmol·g~(-1) and for C_2H_6 it is 1.48 mmol·g~(-1) at 10 kPa. The ideal adsorbed solution theory predicted C_3H_8/CH_4 selectivity is as high as 1857.0, superior to most of the reported materials. Breakthrough experiment results indicated that material could completely separate the C_3H_8/C_2H_6/CH_4 mixture. Therefore, Ni(HBTC)(bipy) is a promising material for separation of natural gas.

Studying an ecological restoration zoning process under the background of ecological security patterns is of great significance to the rapid adjustment and optimization of a landscape pattern. In this study, a remote sensing ecological index and a morphological spatial pattern analysis method were used to assess the quality of habitats and identify ecological sources in the city of Ningbo; ecological corridors, ecological pinch points, and ecological barrier points were extracted by using a circuit theory to construct ecological security patterns and ecological restoration zones. The results indicate: (1) There were 47 ecological sources, and 83 key ecological corridors in Ningbo, and the ecological land area was about 1898.39 km~2, accounting for 19.89% of the total study area. (2) The ecological source areas were distributed in “one patch and three belts”, and the low-resistance ecological corridors were concentrated in southern Yuyao city, western Haishu district, and central and western Fenghua district; the ecological network in the western and southern regions was dense. (3) There were four types of ecological restoration zones that need to be established, which were prioritized restoration zones, prioritized protection zones, key conservation zones, and general conservation zones distributed hierarchically from inner part towards outside. (4) Ninghai county, Yuyao city, and Fenghua district had large ecological land areas, however, prioritized restoration and protection zones in Ninghai and Fenghua were also large. The analysis results are expected to provide a reference for optimizing a territorial ecological space in a city.
冬小麦物候的时空变化模拟及其气候驱动因素解析--基于改进的pDSSAT模型

掌握准确的物候信息及其变化规律和影响机制,对于理解作物对气候变化的响应并制定适应措施具有重要的意义.然而,当前物候信息的获取、驱动因素的解析等均存在不足:如地面观测覆盖范围不全、遥感反演过于依赖传感器、点尺度的作物模型模拟结果难以扩展到区域尺度等.本研究基于Wang-Engel函数改进了CERES-Wheat模型,首先在区域尺度上校准模型并评估了模拟性能,进一步分析了2000~2015年全国冬小麦种植格点物候的时空变化.我们发现改进的模型显著提升了冬小麦种植区开花期(13%)和成熟期(12%)的模拟精度,其中云贵高原区尤为明显(26%和28%);冬小麦生长低温区(如营养生长期均温在0~5℃和15~20℃,生殖生长期在10~15℃范围内)的物候模拟精度也提升显著.该结果证实了模型中原始温度响应函数确实存在局限性.基于区域物候模拟结果表明:近16年来冬小麦关键物候期和生长阶段主要呈提前和缩短趋势,其中开花期、营养生长期和生殖生长期变化具有明显的空间分异特征,如华北平原和长江中下游区的开花期和营养生长期,以及西北地区的生殖生长期均呈现出推迟和延长趋势.敏感性分析结果表明:冬小麦关键物候期和生长阶段会随着最低气温和最高气温的上升而提前和缩短;与之相反的是,随着降水量的增加会推迟和延长;物候期和生长阶段对太阳辐射的响应则未表现出一致性.我们还发现物候对气象因子的敏感性呈现明显的区域特征:如西南和云贵高原区对最低气温、最高气温和太阳辐射变化最为敏感,而华北和西北地区则相反;西北地区物候对降水量的敏感性大于长江中下游区.总之,改进后的作物模型能提供更精细的区域物候空间分异规律,并能更客观地分析出物候时空变化的驱动因子.根据我们的研究,不同冬小麦种植区应采取针对性的适应措施来应对气候变化的影响.最后,改进的模型将提升冬小麦产量的预测精度,该研究也为区域气候变化的影响和适应性评估提供了新方法和新工具.
湖相泥页岩层系富有机质形成与烃类富集--以长7为例

继海相页岩气之后,陆相页岩油成为中国非常规油气的重要勘探领域.但湖相泥页岩形成环境完全不同于海相页岩,导致有机质形成和储集体构成不同,其含油气性和烃类流动性也不同.本文以鄂尔多斯盆地延长组长7段页岩层系为例,剖析了湖相泥页岩形成过程中火山活动对古生产力、保存条件的影响,发现火山喷发之前发育藻类、细菌,而喷发之后,细菌数量下降但藻类较为繁盛,反映了火山活动提高了古生产力;同时,火山活动输入的硫酸盐促使了微生物硫酸盐还原作用发生,产生的H_2S使得水体形成强还原环境,有利于有机质保存.有机地球化学分析表明,泥页岩层系中黑色页岩总有机碳含量高,生烃潜力强,而凝灰岩总有机碳含量低,基本不具备生烃能力,说明火山活动沉积的凝灰岩不能作为有效烃源岩.在储集空间上,泥页岩主要呈现为纹层型和分散型,孔隙为有机孔和无机孔,有机孔发育程度受热成熟度影响,而无机孔主要包含碎屑颗粒和胶结物晶间孔缝;凝灰岩以杂基支撑为主,伴有蚀变,其孔隙包括矿物粒间孔、矿物粒内孔;致密砂岩孔隙发育受压实作用、胶结作用和溶蚀作用影响,孔隙类型主要为粒内孔和粒间孔.长7段湖相泥页岩层系普遍含油,但不同岩性排油效率不同,砂岩排油效率最好,泥页岩最差,其主要受孔径分布、流体性质、岩石润湿性的影响.因此,湖相泥页岩层系页岩油开发应主要集中在含有夹层的泥页岩层系,而泥页岩段有机质与烃类互溶作用使得烃类可动性差,开发难度大.

肾脏固有细胞自噬对肾纤维化作用的研究进展

肾纤维化是各种病因导致的慢性肾脏病(chronic kidney disease,CKD)进展至终末期肾病的共同病理变化,其治疗研究一直受到广泛关注,改善肾纤维化所致的肾功能障碍被认为是治疗CKD的重要策略。自噬作为一种进化上高度保守的细胞内降解系统,已被证实与肾纤维化的发生发展密切相关。其中,肾脏固有细胞自噬变化对肾纤维化的影响被研究得较多;然而,自噬对肾纤维化的作用可能是细胞特异性及疾病环境依赖性的,即在不同的细胞或不同的疾病模型可能有截然相反的作用。因此,自噬对肾纤维化的作用仍然存在一定的争议。本文就肾脏固有细胞自噬在不同疾病条件下对肾纤维化作用的研究进展进行综述。

Finite Groups Whose Norm Quotient Groups Have Cyclic Sylow Subgroups

Let $G$ be a finite group and $N\left( G \right)$ be its norm. Then $N\left( G \right)$ is a characteristic subgroup of $G$ which normalizes every subgroup of $G$. In this paper, we will study the structure of $G$ under one of the following conditions: 1) norm quotient group $G/N\left( G \right)$ is cyclic; 2) all Sylow subgroups of $G/N\left( G \right)$ are cyclic and in particular if the order of $G/N\left( G \right)$ is a square-free number.
