The further development of catalytic elements has been plagued by activation and binary problems.The automatic shift model that has emerged in recent years helps components achieve full range.However,the detection data still remains unstable in the shift area(7%∼13%).This paper proposes a Catalytic Combustion and Thermal Conductivity(CCTC)model for the specified range,which can be explained fromtwo aspects based on the existing methods.On the one hand,it uses iterative location search to process heterogeneous data,judges the prediction position of data points,and then givesweight evaluation.On the other hand,it corrects the abnormal points,determines the abnormal points in the horizontal direction,and gives the replacement value through the data of adjacent points.The experimental results show that the CCTC model reduces the sum of variance from 17 of the automatic shift model to 13,and the comparison of experimental variance is reduced by 23%.In the full-scale real-time data,the experimental variance of CCTC model and automatic shift model is reduced by 18%.In conclusion,CCTC is a cross section stability framework for full-scale methane measurement,in which the specified heterogeneous combination and anomaly point correction methods improve the stability.

Recombinant human interferon a2b(rhIFNa2b)is widely used as an antiviral therapy agent for the treatment of hepatitis B and hepatitis C.The current identification test for rhIFNa2b is complex.In this study,an anti-rhIFNa2b nanobody was discovered and used for the development of a rapid lateral flow strip for the identification of rhIFNa2b.RhIFNa2b was used to immunize an alpaca,which established a phage nanobody library.After five steps of enrichment,the nanobody I22,which specifically bound rhIFNa2b,was isolated and inserted into the prokaryotic expression vector pET28a.After subsequent purification,the physicochemical properties of the nanobody were determined.A semiquantitative detection and rapid identification assay of rhIFNa2b was developed using this novel nanobody.To develop a rapid test,the nanobody I22 was coupled with a colloidal gold to produce lateral-flow test strips.The developed rhIFNa2b detection assay had a limit of detection of 1 mg/mL.The isolation of I22 and successful construction of a lateral-flow immunochromatographic test strip demonstrated the feasibility of performing ligand-binding assays on a lateral-flow test strip using recombinant protein products.The principle of this novel assay is generally applicable for the rapid testing of other commercial products,with a great potential for routine use in detecting counterfeit recombinant protein products.

The crystallization behavior of polyamide 6,6(PA66) under complex flow field is of great importance for its final mechanical properties.Poly(vinyl pyrrolidone)(PVP) was applied as crystallization modifying agency to improve processability of PA66.The regulation nature on hydrogen bonds(H-bonds) interaction of PVP was studied upon cooling process.As revealed by in situ FTIR,the sample with 5 wt% PVP displays decreased enthalpy change(ΔH) for both the generation of H-bonds and the transition of H-bonds from “disordered” to “ordered” state,which illustrates the molecular mechanism for the regulation of crystallzation behavior.Moveover,2D-WAXD is applied to reveal the evolution of microstructure for sample under external injection field.Hermans orientation factor(f_(H)) decreases obviously with the addition of PVP,because the relaxation of chain segments is promoted as well the crystallization is retarded.The above crystallization and microstructure changes during the processing provokes the improvement of processability without the apparent sacrifice of mechanical properties.

This study aimed at evaluating the possibility and effectiveness of osteoinductive bioceramics to fill the tumor cavity following the curettage of sacral giant cell tumor(GCT).Six patients(four females and two males,25–45 years old)underwent nervesparing surgery,in which the tumor was treated by denosumab,preoperative arterial embolization and extensive curettage.The remaining cavity was filled with commercial osteoinductive calcium phosphate(CaP)bioceramics,whose excellent osteoinductivity was confirmed by intramuscular implantation in beagle canine.All patients were followed by computed tomography(CT)scans postoperatively.According to the modified Neer criterion,five cases obtained Type I healing status,and one case had Type II.At the latest follow-up,no graft-related complications and local recurrence were found.The CT scan indicated a median time of healing initiation of 3months postoperatively,and the median time for relatively complete healing was 12months.The excellent bone regenerative ability of the ceramics was also confirmed by increased CT attenuation value,blurred boundary and cortical rim rebuilding.In conclusion,osteoinductive CaP bioceramics could be an ideal biomaterial to treat the large remaining cavity following extensive curettage of sacral GCT.However,further investigation with more cases and longer follow-up was required to confirm the final clinical effect.

西夏建国时期各方政治互动的过程性文本显示,党项李氏在唐朝旧疆建立夏国的结构性进程被后人追述的线性历史叙事简化了。从区域视角看,定难军整合时期党项李氏权力从世袭节度使的李继捧支系转移到李继迁支系,实质是李继迁以抵制“直隶化”的政治策略重塑区域秩序的过程;由此衍生的西向整合进程既利用了唐朝以来的区域政治传统,也利用了辽、宋竞争的时代制度环境,是多种政治资源叠层构造的政治空间。由于政治文化和战略目标差异,共享的区域政治符号在党项李氏、宋朝、辽朝间演绎出不同的权力谱系,不断分化使官号标识的区域政治规范弹性耗尽,庆历年间三方通过宋辽政治共识和宋夏盟约达成妥协,形成西夏建国后区域政治秩序的新规范。

Length-biased data are encountered in many fields,including economics,engineering and epidemiological cohort studies.There are two main challenges in the analysis of such data:the assumption of independent censoring is violated and the assumed model for the underlying population is no longer satisfied for the observed data.In this paper,a proportional mean residual life varyingcoefficient model for length-biased data is considered and a local pseudo likelihood method is proposed for estimating the coefficient functions in the model.Asymptotic properties are investigated for the proposed estimators.The finite sample performance of the proposed methodology is demonstrated by simulation studies.Finally,the method is applied to a real data set concerning the Academy Awards.

High salt is a major environmental factor that threatens plant growth and development.Increasing evidence indicates that histone acetylation is involved in plant responses to various abiotic stress;however,the underlying epigenetic regulatory mechanisms remain poorly understood.In this study,we revealed that the histone deacetylase OsHDA706 epigenetically regulates the expression of salt stress response genes in rice(Oryza sativa L.).OsHDA706 localizes to the nucleus and cytoplasm and OsHDA706 expression is significantly induced under salt stress.Moreover,oshda706 mutants showed a higher sensitivity to salt stress than the wild-type.In vivo and in vitro enzymatic activity assays demonstrated that OsHDA706 specifically regulates the deacetylation of lysines 5 and 8 on histone H4(H4K5and H4K8).By combining chromatin immunoprecipitation and mRNA sequencing,we identified the clade A protein phosphatase 2C gene,OsPP2C49,which is involved in the salt response as a direct target of H4K5 and H4K8 acetylation.We found that the expression of OsPP2C49 is induced in the oshda706 mutant under salt stress.Furthermore,the knockout of OsPP2C49 enhances plant tolerance to salt stress,while its overexpression has the opposite effect.Taken together,our results indicate that OsHDA706,a histone H4 deacetylase,participates in the salt stress response by regulating the expression of OsPP2C49 via H4K5 and H4K8 deacetylation.
