In-situ polymerized electrolytes significantly enhance the interfacial compatibility of lithium metal batteries(LMBs). Typically,in-situ polymerized 1,3-dioxolane(PDOL) exhibits low interfacial resistance, yet still suffers from low ionic conductivity and a narrow electrochemical stability window(ESW). Here, an ultra-stable PDOL-based polymer electrolyte is developed by incorporating plasticizers of tetramethylene sulfone(TMS) and fluorinated ethylene carbonate(FEC) into the 3D cross-linked network, achieving a significant enhancement in the transport capacity and efficiency of Li-ion. The ionic conductivity reaches3.63×10^(-4)S cm^(-1)even at room temperature, and the transference number(tLi^(+)) is even higher at 0.85. Furthermore, the ESW of this electrolyte can be increased to 4.5 V with the addition of TMS, which forms a thin and robust antioxidant cathode-electrolyte interface(CEI) on the surface of high-voltage LiCoO_(2). FEC generates an inorganic-rich solid-electrolyte interface(SEI) on the Li anode, which effectively inhibits the growth of lithium dendrites. Benefiting from the aforementioned advantages, the highvoltage lithium metal battery demonstrates outstanding long-cycle stability, with 93.2% capacity retention after 200 cycles. This work offers a straightforward and accessible method for the practical implementation of high energy density in-situ polymerized solid-state LMBs.

The Hessian fly(HF,Mayetiola destructor)is one of the destructive pests of wheat(Triticum aestivum L.)worldwide.Resistant cultivars can effectively minimize wheat damage due to this insect pest.To identify new quantitative trait loci(QTL)for HF resistance,a population of recombinant inbred lines(RILs)was developed from a cross between the HF-resistant wheat cultivar‘Chokwang’and susceptible wheat‘Ning 7840’,and phenotyped for responses to HF attack.A linkage map was constructed using 1147 single nucleotide polymorphism(SNP)markers generated from genotyping-by-sequencing(GBS).One major QTL,QHf.hwwg-6 BS,for HF-resistance was identified on chromosome arm 6 BS,which explained up to84.0%of the phenotypic variation and was contributed by Chokwang.Two RILs showed recombination in the candidate interval of QHf.hwwg-6 BS,which delimited QHf.hwwg-6 BS to a 4.75 Mb physical interval between 6,028,601 bp and 10,779,424 bp on chromosome arm 6 BS of IWGSC Chinese Spring reference genome Ref Seq v2.0.Seven GBS-SNPs in the candidate interval were converted into Kompetitive allele specific polymerase chain reaction(KASP)markers.Two of them,KASP-6 B112698 and KASP-6 B7901215,were validated in a U.S.winter wheat panel.KASP-6 B112698 was nearly diagnostic,thus can be used to screen QHf.hwwg-6 BS and pyramid it with other resistance genes in breeding programs.

Six chest leads are the standardized clinical devices of diagnosing cardiac diseases.Emerging epidermal electronics technology shift the dangling wires and bulky devices to imperceptible wearing,achieving both comfortable experience and high-fidelity measuring.Extending small areas of current epidermal electronics to the chest scale requires eliminating interference from long epidermal interconnects and rendering the data acquisition(DAQ)portable.Herein,we developed a chest-scale epidermal electronic system(EES)for standard precordial-lead ECG and hydration monitoring,including the onlyμm-thick substrate-free epidermal sensing module and the soft wireless DAQ module.An electrical compensation strategy using double channels within the DAQ module and epidermal compensated branches(ECB)is proposed to eliminate unwanted signals from the long epidermal interconnects and to achieve the desired ECG.In this way,the EES works stably and precisely under different levels of exercise.Patients with sinus arrhythmias have been tested,demonstrating the prospect of EES in cardiac diseases.

Wheat resistance to Fusarium head blight(FHB)has often been associated with some undesirable agronomic traits.To study the relationship between wheat FHB resistance and agronomic traits,we constructed a linkage map of single nucleotide polymorphisms(SNPs)using an F6:8 population from G97252WG97380A.The two hard winter wheat parents showed contrasts in FHB resistance,plant height(HT),heading date(HD),spike length(SL),spike compactness(SC),kernel number per spike(KNS),spikelet number per spike(SNS),thousand-grain weight(TGW)and grain size(length and width).Quantitative trait locus(QTL)mapping identified one major QTL(QFhb.hwwg-2DS)on chromosome arm 2DS for the percentage of symptomatic spikelets(PSS)in the spike,deoxynivalenol(DON)content and Fusarium damaged kernel(FDK).This QTL explained up to 71.8%of the phenotypic variation for the three FHB-related traits and overlapped with the major QTL for HT,HD,SL,KNS,SNS,TGW,and grain size.QTL on chromosome arms 2AL,2DS,3AL and 4BS were significant for the spike and grain traits measured.G97252W contributed FHB resistance and high SNS alleles at QFhb.hwwg-2DS,high KNS alleles at the QTL on 2AL and 2DS,and high TGW and grain size alleles at QTL on 3AL;whereas G97380A contributed high TGW and grain size alleles at the QTL on 2AL and 2DS,respectively,and the high KNS allele at the 4BS QTL.Combining QFhb.hwwg-2DS with positive alleles for spike and grain traits from other chromosomes may simultaneously improve FHB resistance and grain yield in new cultivars.

本科生发表学术论文情况是衡量其科研能力的方式之一,也是评价高校本科生教育质量的指标之一。本研究以42所“双一流”高校本科生为对象,通过问卷调研发现,“双一流”高校本科生科研参与比例达到75.37%,但发表学术论文者仅占23.70%。发表学术论文情况在性别上不存在显著差异,但在年级、科研参与意愿和投入时间上具有显著差异;不同年级学生对撰写学术论文的指导需求不同,参与科研动机存在一定的功利化倾向。本研究建议:首先,制定操作性强的培育政策,完成政策从“虚”到“实”的转变;其次,稳扎稳打做好本科生导师制的各环节工作,完成制度从“浮”到“沉”的转变;最后,尝试创办面向本科生的学术期刊,完成期刊从“无”到“有”的转变,为本科生学术成果交流提供渠道和平台。

This paper presents a compact aggregated unit model（CAUM） for short-term hydro power generation scheduling. The CAUM, which is obtained based on optimal piecewise linear approximation, represents the relationship between the maximum power generation level of the plant, total water discharge and the average storage of the reservoir. Different from the real-time optimal dispatch of the hydropower system, the CAUM is an off-line optimization. Meanwhile, the aggregation of the individual unit simplifies the short-term hydro power generation scheduling since all the individual unit related constraints are removed. By using the CAUM, the optimal power generation level can be rapidly determined and the short-term hydro power generation scheduling would be greatly simplified. Numerical testing results demonstrate that the method is effective.

Although Ganoderma is an important edible and medicinal fungus for producing various kinds of bioactive substances, the available genetic elements for these medicinal mushrooms are still rather limited. In this study, we had isolated and analyzed the promoters of FIP genes from Ganoderma lucidum and G. atrum, respectively. In addition, the FIP genes were expressed by the induction of elicitors, methyl jasmonate（MeJA） and salicylic acid（SA）, with different concentration. Inducible expression results were detected by quantitative reverse transcription-PCR（q RT-PCR）. The results showed that 5’ upstream sequences of FIPs from G. lucidum and G. atrum were obtained, respectively.Sequence analysis showed that the FIP-glu promoter sequence contains eleven CAAT-boxes, three TATA-boxes, three Me JA responsive elements, two MBS motifs, one ABRE, one TGA, one ARE, two circadian, one fungal elicitor, one meristem specific activation element, three Skn-1 motifs, and several light responsive elements;while the 5’-flanking region of the FIP-gat included nine CAAT-boxes, four TATA-boxes, three Me JA responsive elements, one Aux RR-core, one GC-motif, one MBS, one fungal elicitor, one meristem specific activation element, two Skn-1 motifs, and several light responsive elements. On the transcriptional level, both FIP-glu and FIP-gat reached their highest expression levels after treatment of 500 μmol/L of Me JA. After treated with SA among 0 ～ 1,000 mg/L, the accumulation of FIP-glu expression depended on the concentration of SA, and the expression level of FIP-gat gene reached highest at a concentration of 100 mg/L. This research laid the foundation to use Ganoderma mycelium as bioreactor for producing FIPs.
