The Theoretical and Experimental Analysis of the Maximal Information Coefficient Approximate Algorithm

In the era of big data, correlation analysis is significant because it can quickly detect the correlation between factors. And then, it has been received much attention. Due to the good properties of generality and equitability of the maximal information coefficient (MIC), MIC is a hotspot in the research of correlation analysis. However, if the original approximate algorithm of MIC is directly applied into mining correlations in big data, the computation time is very long. Then the theoretical time complexity of the original approximate algorithm is analyzed in depth and the time complexity is n~(2.4) when parameters are default. And the experiments show that the large number of candidate partitions of random relationships results in long computation time. The analysis is a good preparation for the next step work of designing new fast algorithms.
Energy Consumption in China’s Construction Industry: Energy Driving and Driven Abilities from a Regional Perspective

The construction industry is one of the largest energy consumers in China. It not only uses energy directly but also consumes a large amount of embodied energy hidden in intermediate goods and services from other industries. This paper utilizes the multi-regional input-output (MRIO) model to measure the embodied energy consumption in China’s construction industry at the province level. To quantify the backward and forward linkages between the construction industry and other industries, the energy-driven and energy-driving abilities of the construction industry are investigated for 30 provinces. The results show that the values of the energy-driven coefficients are significantly larger than the energy-driving coefficients, indicating that the construction industry is highly dependent on products from other industries and other regions, not vice versa. The construction industries in the southwest and northwest regions of China have the highest energy-driven coefficients, showing that the construction industries in west China heavily rely on indirect energy embodied in goods and services. This particularly applies in Guangxi and Hainan provinces, which have the highest energydriven abilities and the lowest energy-driving abilities. The findings can facilitate the policy-makers to examine the critical energy-saving paths.
Liver transplantation and BCLC classification:Limitations impede optimum treatment

Background:The Barcelona Clinic Liver Cancer (BCLC) system has been endorsed by international guidelines as a staging algorithm of hepatocellular carcinoma.This analysis was performed to assess the outcome of liver transplantation in patients treated against the BCLC recommendations.Methods:The data of 198 patients who underwent liver transplantation for hepatocellular carcinoma were extracted from a prospectively maintained database to classify the patients according to the BCLC system.Results:BCLC staging was as follows:0,n = 5;A,n = 77;B,n = 41;C,n = 53;and D,n = 22.Accordingly,liver transplantation was performed in the majority of patients against BCLC recommendations.Surgery (n = 16),radiofrequency ablation (n = 15) and transarterial chemoembolization (n = 151) preceded liver transplantation in 182 patients.Sixteen patients were transplanted without pretreatment.The 1-,5-and 10-year survival rates were 83.8%,62.4% and 45.9%,and 1-,5-,and 10-year recurrence rates were 7.7%,22.7% and 26.7%.The BCLC classification did neither impact survival (P = 0.796) nor recurrence (P = 0.693).In the Cox analysis,RECIST tumor progression and initial alpha fetoprotein were independent predictors of outcome.Conclusions:Neither the oncological nor the functional stratification imposed by the BCLC system was of importance for outcome.Lack of flexibility and disregard of biological parameters hamper its clinical applicability in liver transplantation.
NO_x storage and reduction assisted by non-thermal plasma over Co/Pt/Ba/γ-Al_2O_3 catalyst using CH_4 as reductant

NO_x storage and reduction (NSR) technology has been regarded as one of the most promising strategies for the removal of nitric oxides(NO_x) from lean-burn engines, and the potential of the plasma catalysis method for NO_x reduction has been confirmed in the past few decades. This work reports the NSR of nitric oxide (NO) by combining non-thermal plasma (NTP) and Co/Pt/Ba/γ-Al 2 O3 (Co/PBA) catalyst using methane as a reductant. The experimental results reveal that the NO x conversion of NSR assisted by NTP is notably enhanced compared to the catalytic efficiency obtained from NSR in the range of 150 °C-350 °C, and NO x conversion of the 8% Co/PBA catalyst reaches 96.8% at 350C. Oxygen (O2) has a significant effect on the removal of NO_x, and the NO x conversion increases firstly and then decreases when the O2 concentration ranges from 2% to 10%. Water vapor reduces the NO_x storage capacity of Co/PBA catalysts on account of the competition for adsorption sites on the surface of Co/PBA catalysts. There is a negative correlation between sulfur dioxide (SO2) and NO_x conversion in the NTP system, and the 8% Co/PBA catalyst exhibits higher NO_x conversion compared to other catalysts, which shows that Co has a certain SO_2resistance.
Spatial Distribution and Ecological Risk Assessment of Heavy Metals in Surface Sediment of Songhua River,Northeast China

The Songhua River,one of the seven major rivers in China,locates in Northeast China with 1897 km long.This study aims to investigate the concentrations,distribution,source apportionment and ecological risk assessment of heavy metals including copper(Cu),zinc(Zn),cadmium(Cd),lead(Pb),nickel(Ni)and chromium(Cr)in main stream and tributaries of the Songhua River in Jilin Province,Northeast China.Surface sediment samples(0-15 cm)were collected from 39 sampling sites in the Songhua River in July 2012.Concentrations of Cu,Zn,Cd,Pb,Ni and Cr were analyzed.The mean concentrations of heavy metals were(24.0 ± 9.2)mg/kg,(59.3 ± 18.0)mg/kg,(4.0 ± 2.1)mg/kg,(39.0 ± 27.9)mg/kg,(18.5 ± 8.6)mg/kg and(56.1 ± 17.6)mg/kg for Cu,Zn,Cd,Pb,Cr and Ni,respectively.The average contents of Cu,Cd,Pb,Cr and Ni were higher than their background values.Higher concentrations of heavy metals were found in the lower reaches with industrial enterprises and cities along the Songhua River.Zn,Pb and Ni might come from industrial sewage and mineral processing,while Cu and Cd were derived from electroplating wastewater and agricultural non-point source sewage.Cr originated from lithogenic sources.The concentrations of Cu,Zn and Cr were below the effect range low(ERL)at all sites,while Cd,Pb and Ni concentrations were detected ranging from ERL to the effect range median(ERM)at more than 15% of samples.Concentrations of Ni exceeded ERM in more than 50% of samples.The mean toxic units of heavy metals in the Songhua River decreased following the order:Cd(6.7)>Pb(2.2)>Ni(1.6)>Cu(0.7)>Cr(0.5)= Zn(0.5).Potential ecological risk index was found to be higher in middle and lower reaches of the Songhua River,where Cd could impose an extremely high ecological risk.
Land Use/Cover Change and Its Policy Implications in Typical Agriculture-forest Ecotone of Central Jilin Province,China

During the 21st century,policies toward agriculture,forestry,and urbanization have emerged to ensure food security,ecological restoration,and human well-being by managing land in Northeast China.However,the integrated effects and relationships of various policies are still not well understood.This study observed the land use land cover changes in Central Jilin from 2000 to 2019 and,by considering policy involvement,aimed to understand the effects and trade-offs of policies.Results showed that the cropland,including dryland and rice paddy,and the forest,including coniferous forest and deciduous forest,are dominant land types in Central Jilin.During 2000-2019,the land changed diversely,of which the main changes were the expanded dryland(+0.43 million ha),the increased deciduous forest(+22 million ha),the decreased coniferous forest(-0.08 million ha),and the expanded urban settlement(+0.04 million ha).With these changes,despite the unit grain yield showing a rising trend,the yield contribution of Central Jilin to the national total decreased.The poor cultivating structure made for the cropland expansion and reduced the implementation space of environmental restoration projects such as the Grain to Green.Thus,in Central Jilin that transits from the agri-food production zone to the eco-regulation zone,environmental projects coexisted in a trade-off manner with agricultural policies that aim to liberate agricultural productivity.In the key urban agglomerations of Central Jilin,the increase in the proportion of green space improved the thermal environment and carbon balance.The gross domestic product of the large city and its local proportion also rose.These improvements benefited from the promotion of development policies and urbanization policies at key time points.In the future,it is necessary to coordinate agricultural policies and environmental projects and promote the progress of small-and medium-sized cities to ensure the equality of regional development.This study has implications for making decisions to revitalize Northeast China and researchers who inform decisions.
Morphological,physiological and biochemical traits of Cordia trichotoma under phosphorous application and a water-retaining polymer

The application of phosphorus (P) and a waterretaining polymer to the soil can increase the availability of P for Cordia trichotoma,having a positive effect on the plants.The objective of this study was to evaluate the morphological,physiological and biochemical characteristics of C.trichotoma plants were cultivated in a red argisol and treated with 120,240 and 360 kg P_2O_5 ha~(–1) and no phosphorous addition as a control,in the presence (5 g L~(–1) per seedling) and absence of a water-retaining polymer.Twentyfour months after planting,survival,height,stem diameter,shoot and root dry matter,leaf area,photosynthetic pigment concentration,chlorophyll a fluorescence,acid phosphatase enzyme activity (APase) and P in tissues and soil were determined.The polymer had no effect on survival and the other parameters.The addition of P increased growth,dry matter production,photosynthetic pigment concentrations,the use of light energy and maximum quantum yield of photosystem II.Plants cultivated in soil with 240 kg P_2O_5 ha~(–1) application had 4.7 and 5.4 times more shoot and root dry matter,respectively,than control plants.This dosage also showed 52.1% greater photochemical energy use than the control plants.Plants cultivated without the addition of P showed higher activity of the APase enzyme.
Effects of pruning intensity on nonstructural carbohydrates of Populus alba × P.talassica in the arid desert region of Northwest China

Although pruning is important to obtain highquality,large-diameter timber,the effects of pruning on nonstructural carbohydrates (NSC) in aboveground organs of many timber species are not well understood.Three intensities of pruning (none,moderate and severe) were tested on poplars (Populus alba × P.talassica) in the arid desert region of northwest China to compare the concentrations of soluble sugar (SS),starch (ST) and total nonstructural carbohydrate (TNC) in leaves,branches and trunks during the growing season.The concentration of NSC components after different pruning intensities varied similarly in seasonal patterns,increasing slowly at the beginning of the growing season,continuously declining in the middle,then gradually recovering by the end of the growing season.The monthly mean NSC concentration in poplar differed significantly among the three pruning intensities (p <0.05).The SS concentration in pruned trees was higher than in unpruned trees (p <0.05).For moderately pruned trees,the concentrations of ST and TNC in trunks and branches were higher than in unpruned and in severely pruned trees (p <0.05).Compared with no pruning,pruning changed the seasonal variation in NSC concentration.The orders of SS and TNC concentrations in aboveground organs were leaf >branch >trunk,while the order of ST concentration was trunk >leaf >branch,which was related to functional differences of plant organs.The annual average growth in height of unpruned,moderately pruned,and severely pruned poplars was 0.21 ± 0.06,0.45 ± 0.09 and 0.24 ± 0.05 m,respectively,and the annual average growth in DBH were 0.92 ± 0.04,1.27 ± 0.06 and 1.02 ± 0.05 cm,respectively.Our results demonstrate that moderate pruning may effectively increase the annual growth in tree height and DBH while avoiding damage caused by excessive pruning to the tree body.Therefore,moderate pruning may increase the NSC storage and improve the growth of timber species.
Waterlogging tolerance and wood properties of transgenic Populus alba × glandulosa expressing Vitreoscilla hemoglobin gene (Vgb)

Because overexpression of Vitreoscilla hemoglobin gene (Vgb) gene in plants can enhance tolerance to waterlogging,here Vgb was inserted into Populus alba × glandulosa to investigate its expression and effects on growth and physiological responses to waterlogging stress in the transgenic poplars.Southern blotting and RT-PCR analysis of Vgb-transgenic P.alba × glandulosa showed that the Vgb gene was integrated into the genome of the V13-81 and V13-85 transgenic lines and expressed.In greenhouse waterlogging stress tests,mortality of the transgenic poplar was significant lower than that of nontransgenic plants with increasing treatment time from 2 to 22 days.The transgenic plants had higher chlorophyll content and less chloroplast damage than in the control plants.Additionally,starch accumulation increased,and growth was enhanced in the transgenic plants,suggesting that the Vgb-expressing lines had improved energy reserves.Field trials of the transgenic poplar suggested that Vgb expression promotes growth and influences wood quality.Taken together,our results suggest that the expression of Vgb can increase the accumulation of chlorophyll and starch in the transgenic poplar,improve its ability to endure flooding,and improve growth and wood quality of the transgenic plants.
Ecological variations of woody species along an altitudinal gradient in the Qinling Mountains of Central China:area-based versus mass-based expression of leaf traits

Leaf trait-based research has become the preferred method to understand the ecological strategies of plants.However,there is still a debate on whether area-based or mass-based traits provide different insights into environmental adaptations and responses.In this study,seven key leaf traits (maximum net photosynthetic rate,dark respiration rate,nitrogen content,photosynthetic nitrogen use efficiency,leaf mass per area,leaf dry matter contents and leaf area) of 43 woody species were quantified on the basis of both area and mass along an altitudinal gradient (1100- 2700 m) in the Qinling Mountains of China.Differences in leaf traits and bivariate correlations between the two expressions were compared.By considering different expressions,the strengths and directions of the responses of leaf traits to the altitudinal gradient were determined.Leaf traits showed large variations;interspecific variations contributed more to total variance than intraspecific variations.Bivariate correlations between photosynthetic traits and structural traits (mass per area,dry matter content,and area) were weaker on a mass basis than those on an area basis.Most traits exhibited quadratic trends along the altitudinal gradient,and these patterns were more noticeable for area-based than mass-based traits.Area-based traits were more sensitive to changes in temperature and precipitation associated with altitude.These results provide evidence that mass-versus area-based traits show different ecological responses to environmental conditions associated with altitude,even if they do not contain very broad spatial scales.Our results also indicate distinction of photosynthetic acclimation among the two expressions along an altitudinal gradient,reflecting trade-offs among leaf structure and physiological traits.
病例224:38岁男性动脉导管未闭合并艾森曼格综合征介入治疗

笔者所在中心目前已完成各类先天性心脏病合并艾森曼格综合征的介入治疗10例,10例患者有9例成功试封堵,1例试封堵后出现急性右心衰竭症状。这些患者成功试封堵进一步验证了双向分流、艾森曼格综合征不是介入封堵术的禁忌证。成功试封堵患者中,术前最高肺动脉压达190 mm Hg,失败患者肺动脉压为94 mm Hg。结合前人研究,笔者认为,肺动脉压高低不是判断能否试封堵的条件,肺动脉压高也不等同于出现阻力性PAH。目前也尚未知临床上哪些指标可判断先天性心脏病合并PAH患者可成功试封堵。从临床经验上说,术前能否足量应用3种靶向药、是否出现紫绀、急性肺血管反应试验结果、右心导管检查中Qp/Qs,决定了试封堵的成功率。综上,现阶段先天性心脏病合并PAH的介入诊疗多基于临床经验,相关基础研究和临床研究均是未来的科研方向。

界面能带结构是指界面处电子能带的弯曲和倾斜。它能显著影响载流子的产生、注入、分离、传输、复合和收集等过程,是半导体光电子器件性能的重要影响因素。因此,优化界面能带结构、调控器件性能与工作机理是光电子器件领域的核心课题之一。如果将一组相距很近的正负点电荷肩并肩排列所组成的偶极层插入器件界面,电势能穿过偶极层时会发生突变,将能有效调控界面能带结构和载流子运动过程。
Transcription factor ZmNAC126 plays an important role in transcriptional regulation of maize starch synthesis-related genes

Maize (Zea mays L.) is one of the most important food crops in the world,and starch is the main component of its endosperm.Transcriptional regulation plays a vital role in starch biosynthesis.However,it is not well understood in maize.We report the identification of the transcription factor ZmNAC126 and its role in regulation of starch synthesis in maize.Transcriptional expression of ZmNAC126 was higher in maize endosperm and kernels than in roots or stems.ZmNAC126 shared a similar expression pattern with starch synthesis genes during seed development,and its expression pattern was also consistent with the accumulation of starch.ZmNAC126 is a typical transcription factor with a transactivation domain between positions 201 and 227 of the amino acid sequence,is located in the nucleus,and binds to CACG repeats in vitro.Yeast one-hybrid assay revealed that ZmNAC126 bound the promoters of ZmGBSSI,ZmSSIIa,ZmSSIV,ZmISA1,and ZmISA2.Transient overexpression of ZmNAC126 in maize endosperm increased the activities of promoters pZmSh2,pZmBt2,pZmGBSSI,pZmSSIIIa,and pZmBT1 but inhibited the activities of pZmISA1 and pZmISA2.ZmNAC126 thus acts in starch synthesis by transcriptionally regulating targeted starch synthesis-related genes in maize kernels.
De novo assembly of chloroplast genomes of Corchorus capsularis and C.olitorius yields species-specific InDel markers

Jute (Corchorus spp.) is a member of the Malvaceae family,which comprises more than 100 species.The systematic positions of jute species have remained unsettled.Chloroplasts are maternally inherited and their genomes are widely used for plant phylogenetic studies.In the present study,the chloroplast genomes of Corchorus capsularis and C.olitorius were assembled,with sizes of respectively 161,088 and 161,766 bp.Both genomes contained 112 unique genes (78 protein-coding,four rRNA,and 30 tRNA genes).Four regionswith high variation between the two species were located in single-copy rather than inverted-repeat regions.A total of 66 simple sequence repeats (SSRs)were identified in the C.capsularis chloroplast genome and 56 in that of C.olitorius.Comparison of the two chloroplast genome sequences permitted the evaluation of nucleotide variation including 2417 single-nucleotide polymorphisms sites and 294 insertion or deletion sites,of which one marker (cpInDel 205) could discriminate the two jute species.Comparison of the C.capsularis and C.olitorius chloroplast genomeswith those of other species in theMalvaceae revealed breakpoints in the accD locus,which is involved in fatty acid synthesis,in C.capsularis and C.olitorius.This finding suggests that genes from the chloroplast genomemight have been transferred to the nuclear genome in some Corchorus species.This hypothesis was supported by synteny analysis of the accD region among the nuclear,chloroplast,and mitochondrial genomes.To our knowledge,this is the first report of the assembled chloroplast genome sequences of C.capsularis and C.olitorius.C.capsularis and C.olitorius are closely related to Gossypium species and there are abundant microstructure variations between these two genera.These results will expand our understanding of the systematics of species in the Malvaceae.
Functional hydrogel coatings

Hydrogels-natural or synthetic polymer networks that swell in water-can be made mechanically, chemically and electrically compatible with living tissues. There has been intense research and development of hydrogels for medical applications since the invention of hydrogel contact lenses in 1960. More recently, functional hydrogel coatings with controlled thickness and tough adhesion have been achieved on various substrates. Hydrogel-coated substrates combine the advantages of hydrogels, such as lubricity, biocompatibility and anti-biofouling properties, with the advantages of substrates, such as stiffness, toughness and strength. In this review, we focus on three aspects of functional hydrogel coatings: (i) applications and functions enabled by hydrogel coatings, (ii) methods of coating various substrates with different functional hydrogels with tough adhesion, and (iii) tests to evaluate the adhesion between functional hydrogel coatings and substrates. Conclusions and outlook are given at the end of this review.
Rapid generation of ACE2 humanized inbred mouse model for COVID-19 with tetraploid complementation

Although monkeys and pigs can be infected with SARS-CoV-2, they generally have a long growth cycle and a large size that is difficult to handle in large quantities. However, the readily available rats and mice are not susceptible to SARSCoV-2 because of differences in ACE2 (angiotensin-converting enzyme 2), the receptor mediating cell entry of SARSCoV-2. Thus, the key to establishing a mouse model of COVID-19 is to make the mice express human ACE2 protein, and therefore become SARS-CoV-2 susceptible.
