Genetic mapping provides a powerful tool for quantitative trait loci （QTL） analysis at the molecular level. A simple sequence repeat （SSR） genetic map containing 590 markers and a BCI population from two cultivated tetraploid cotton （Gossypium hirsutum L.） cultivars, namely TM-1 and Hai 7124 （G. barbadense L.）, were used to map and analyze QTL using the composite interval mapping （CIM） method. Thirty one QTLs, 10 for lobe length, 13 for lobe width, six for lobe angle, and two for leaf chlorophyll content, were detected on 15 chromosomes or linkage groups at logarithm of odds （LOD）≥2.0, of which 15 were found for leaf morphology at LOD≥3.0. The genetic effects of the QTL were estimated. These results are fundamental for marker-assisted selection （MAS） of these traits in tetraploid cotton breeding.

中国当代艺术中的文字模型及其认知机制

多数情形下,文字被视为具有解释和命名功能的媒介,这种认知方式来自稳固的书写经验和审美习惯。然而,汉语文字自身的象形特征、符号功能,及其依附的载体、显现的空间与书写肢体间构成的更为立体的认知,凸显了文字在创作中独有的价值。... 详细信息

多数情形下,文字被视为具有解释和命名功能的媒介,这种认知方式来自稳固的书写经验和审美习惯。然而,汉语文字自身的象形特征、符号功能,及其依附的载体、显现的空间与书写肢体间构成的更为立体的认知,凸显了文字在创作中独有的价值。文中试图以20世纪80年代以来的文字作品为对象,采用"建模"的方式,在更为本质的层面将文字视为一种分配方式,对其建构的路径进行综合系统的分析,进而挖掘文字机制不断交织和生效的可能性。文中勾勒了四种文字的模型及其认知机制:意指符号-地域政治的修辞;展示机制-认知结构的召唤;流动句法-潜文本的幽灵;赤裸图形-无界沟通的复归。四种认知机制以不同的途径塑造着文字的命运,它们以相异的路径独立彼此,又以流动的形态交叉,勾勒的不仅是文字的演变逻辑,更是基于如何运作和行进的深层认知所建立的"可动的文字观"。

The microstructural evolution of a cold-rolled and intercritical annealed medium-Mn steel(Fe-0.10C-5Mn)was investigated during uniaxial tensile ***-situ observations under scanning electron microscopy,transmission electron microscopy,and X-ray diffraction analysis were conducted to characterize the progressive transformation-induced plasticity process and associated fracture initiation *** findings were discussed with the local strain measurements via digital image *** results indicated that Lüders band formation in the steel was limited to 1.5%strain,which was mainly due to the early-stage martensitic phase transformation of a very small amount of the less stable large-sized retained austenite(RA),which led to localized stress concentrations and strain hardening and further retardation of *** small-sized RA exhibited high stability and progressively transformed into martensite and contributed to a stably extended Portevin-Le Chatelier *** volume fraction of RA gradually decreased from 26.8%to 8.2%prior to *** the late deformation stage,fracture initiation primarily occurred at the austenite/martensite and ferrite/martensite interfaces and the ferrite phase.

One of the primary goals of space-borne gravitational wave detectors is to detect and analyze extreme-mass-ratio inspirals(EMRIs). This task is particularly challenging because EMRI signals are complex, lengthy, and faint. In this work, we introduce a2-layer convolutional neural network(CNN) approach to detect EMRI signals for space-borne detectors, achieving a true positive rate(TPR) of 96.9% at a 1% false positive rate(FPR) for signal-to-noise ratio(SNR) from 50 to 100. Especially, the key intrinsic parameters of EMRIs such as the mass, spin of the supermassive black hole(SMBH) and the initial eccentricity of the orbit can also be inferred directly by employing a neural network. The mass and spin of the SMBH can be determined at 99% and 92% respectively. This will greatly reduce the parameter spaces and computing cost for the following Bayesian parameter *** model also has a low dependency on the accuracy of the waveform model. This study underscores the potential of deep learning methods in EMRI data analysis, enabling the rapid detection of EMRI signals and efficient parameter estimation.

以模拟生活污水为处理对象,采用序批式反应器(SBR)单污泥系统,通过A/O、A/A/O、A/A三阶段运行的方式,研究了反硝化除磷的启动条件,并考察了亚硝酸盐浓度的影响。结果表明,丙酸钠为反硝化除磷菌(DPBs)的理想碳源,通过控制短污泥龄(SRT)驯化聚磷菌(PAOs),再延长SRT至25 d富集DPBs,系统运行45 d即成功启动了反硝化除磷工艺,PO_(4)^(3-)-P去除率稳定在80%以上。启动成功后,DPBs占PAOs的比例从28.5%升至75.8%。在富集完PAOs后,可利用NO_(2)^(-)-N作为电子受体的浓度仅为4 mg/L,达到8 mg/L时则会出现吸磷抑制现象;而DPBs富集完成后,NO_(2)^(-)-N抑制浓度阈值提高至12 mg/L,此时净吸磷量仅有8.58 mg/L。

In the intricate process of natural product biosynthesis, a metabolon can enhance metabolic flux by associating sequential enzymes. A fungal metabolon, comprising of flavin-dependent monooxygenase Spe F and P450 monooxygenase Spe G, is identified in the biosynthesis of spiro polycyclic alkaloids(+)-notoamide B and its diastereomer(+)-versicolamide B. Using notoamide E as a substance, Spe F/Spe G metabolon can control the stereoselectivity of its 2,3-epoxidation, followed by hydrogen atom ion at C-17 to generate reactive epoxide tau-m A with dienyl iminium unit. Subsequently,(+)-notoamide B and(+)-versicolamide B are produced via tandem nonenzymatic inverse-electron-demand Diels-Alder reaction and semipinacol rearrangement. This provides the first example of metabolon in the biosynthesis of spiro-prenylated indole alkaloids.
