A Coupling Magneto-Electro-Elastic(MEE)Node-based Smoothed Radial Point Interpolation Method(CM-NS-RPIM)was proposed to solve the free vibration and transient responses of Functionally Graded Magneto-Electro-Elastic(FGMEE)structures.By introducing the modified Newmark method,the displacement,electrical potential and magnetic potential of the structures under transient mechanical loading were obtained.Based on G space theory and the weakened weak(W2)formulation,the equations of the multi-physics coupling problems were derived.Using triangular background elements,the free vibration and transient responses of three numerical examples were studied.Results proved that CM-NS-RPIM performed better than the standard FEM by reducing the overly-stiff of structures.Moreover,CM-NS-RPIM could reduce the number of nodes while guaranteeing the accuracy.Besides,triangular elements could be generated automatically even for complex geometries.Therefore,the effectiveness and validity of CM-NS-RPIM were demonstrated,which were valuable for the design of intelligence devices,such as energy harvesters and sensors.

上海音乐学院历经九十多年的积淀,聚集了一大批德高望重的学者,这些蜚声海内外的名家都被我们尊称为“先生”。现在的年轻学子们则统一称“老师”或者“教授”,鲜少叫“先生”。但是,在今天的学院理里江明惇却被大家一致称呼为“江先生”。这或许延续着某种潜在的默契。每当在校园见到他的时候,学生们都会恭敬的问候,他总是温文尔雅、细语轻声。江先生一生挚爱民间艺术的研究,他的名著《汉族民歌概论》《中国民间音乐概论》等张扬着中国民族文化深厚磅礴的气韵。

Gas hydrates have drawn global attentions in the past decades as potential energy resources.It should be noted that there are a variety of possible applications of hydrate-based technologies,including natural gas storage,gas transportation,separation of gas mixture,and seawater desalination.These applications have been critically challenged by insufficient understanding of hydrate formation kinetics.In this work,the literatures on growth kinetic behaviors of hydrate formation from water-hydrocarbon were systematically reviewed.The hydrate crystal growth,hydrate film growth and macroscopic hydrate formation in water system were reviewed,respectively.Firstly,the hydrate crystal growth was analyzed with respect to different positions,such as gas/liquid interface,liquid–liquid interface and gas–liquid–liquid system.Secondly,experimental and modeling studies on the growth of hydrate film at the interfaces between guest phase and water phase were categorized into two groups of lateral growth and thickening growth considering the differences in growth rates.Thirdly,we summarized the promoters and inhibitors reported(biological or chemical,liquid or solid and hydrophobic or hydrophilic)and analyzed the mechanisms affecting hydrate formation in bulk water system.Knowledge gaps and suggestions for further studies on hydrate formation kinetic behaviors are presented.

Dear Editor, Although various components of the Wnt/β-catenin pathway have been investigated, there are conflicting reports on the roles of Wnt/β-catenin signaling in oligodendrogenesis and differentiation. For instance, the △Exon3 mutation of β-catenin[14], which stabilizes β-catenin by deletion of the phosphorylation site for the destruction complex, significantly inhibits the differentiation of oligodendrocytes, but knockout of β-catenin also delays it.

The overuse of nitrogen(N)fertilizer in fields has increased production costs and raised environmental concerns.Increasing the N use efficiency(NUE)of rice varieties is crucial for sustainable agriculture.Here we report the cloning and characterization of OsNPF3.1,a gene that controls rice NUE.An amino acid mutation in the OsNPF3.1 coding region caused different NUEs in wild and cultivated rice.OsNPF3.1,which is expressed mainly in the aerial parts of rice,also affects rice plant height,heading date,and thousand-grain weight.The OsNPF3.1 protein is located in the plasma membrane.When OsNPF3.1 was subjected to artificial selection,two naturally varying loci were associated with NUE,of which OsNPF3.1Chr6_8741040differed between indica and japonica rice.OsNPF3.1 can be used as a new target gene for breeding rice varieties with high NUE.

Using a new ground-state ab initio potential energy surface reported by Deskevich et al.,the product polarizations in the reactions F+HCl→HF+Cl and F+DCl→DF+Cl were studied by employing the quasi-classical trajectory method.At a collision energy of 10 kcal/mol,the four generalized polarization-dependent differential cross-sections(2π/σ)(dσ00/dωt),(2π/σ)(dσ20/dωt),(2π/σ)(dσ22+/dωt)and(2π/σ)(dσ21-/dωt)were calculated in the center-of-mass frame.The distribution of the angle between k and j',P(θr),the distribution of the dihedral angle denoting the k-k'-j' correlation,P(φr),and the angular distribution of the product rotational vectors in the form of polar plots P(θr,φr)were also calculated.The evident influence of isotope substitution on the product polarization is revealed.This effect may result from the different mass factors of the two reactions.

Bovine foamy virus encodes a transcriptional transactivitor, Tas or Borf-1, which governs the level of viral transcripts initiated by both the promoter in the long terminal repeat (LTR) and the internal promoter (IP) located in the env gene through their cis-acting targets. We have identified and characterized a 72 bp TBS (Borf-1) responsive element located in BFV3026, internal promoter (TREIP) by deletion mutant and transient expression assay. This cis-acting target element in the internal promoter has the properties of a transcriptional enhancer which functions independently of its orientation, position and also in heterologous promoters (BFV LTR and bovine immunodeficiency virus, BIV LTR). Alignments reveal that there are positional similarity and sequence homology among BFV TREIP, SFV-1 TREIP proximal element and SFV-3 TREIPH, which suggests that this kind of cis-acting elements possesses some common functional character.
