Although mitochondria provide eukaryotic cells with certain metabolic advantages, in other ways they may be disadvantageous. For example, mitochondria produce reactive oxygen species that damage both nucleocytoplasm and mitochondria, resulting in mutations, diseases, and aging. The relationship of mitochondria to the cytoplasm is best understood in the context of evolutionary history. Although it is clear that mitochondria evolved from symbiotic bacteria, the exact nature of the initial symbiosis is a matter of continuing debate. The exchange of nutrients between host and symbiont may have differed from that between the cytoplasm and mitochondria in modern cells. Speculations about the initial relationships include the following. (1) The pre-mitochondrion may have been an invasive, parasitic bacterium. The host did not benefit. (2) The relationship was a nutritional syntrophy based upon transfer of organic acids from host to symbiont. (3) The relationship was a syntrophy based upon H2 transfer from symb

Acta Mathematica Scientia 2009年第6期29卷 1749-1766页

In this paper we show how the simplest wave structure that balances compression and rarefaction in the nonlinear compressible Euler equations can be represented in a solution of the linearized compressible Euler equations. Such waves are exact solutions of the equations obtained by linearizing the compressible Euler equations about the periodic extension of two constant states separated by entropy jumps. Conditions on the states and the periods are derived which allow for the existence of solutions in the Fourier 1-mode. In [3, 4, 5] it is shown that these are the simplest linearized waves such that, for almost every period, they are isolated in the kernel of the linearized operator that imposes periodicity, and such that they perturb to nearby nonlinear solutions of the compressible Euler equations that balance compression and rarefaction along characteristics in the formal sense described in [3]. Their fundamental nature thus makes them of interest in their own right.

Introduction The molecular dynamics simulation technique has recently proved to be a suitable alternative approachfor simulation of vibrational spectroscopy. In this study, molecular dynamics was utilized to understandlow frequency vibrations in highly ordered poly(ρ-phenylene terephthalmide) (PPTA). A key structuralfeature of this polymer is the presence of hydrogen bonds. There is little question that this strong localized

兰斯顿.休斯的短篇小说"神圣的保证"引发了当代批评家们关于休斯对同性恋态度的种种争论。但值得关注的是,休斯是从第三人称有限全知视角来写作这部短篇小说的,仅仅展示了父亲约翰的心理活动,却没有涉及故事中其他人物的心理活动。但由于约翰具有明显的同性恋恐慌症式的偏见,好妄加判断,对何为"正常"的美国家庭有着先入为主的观念,这些都有可能扭曲、模糊他观察戴利的场景的真实性,因此,我们不得不质疑约翰对其子戴利的种种想当然的猜测。其实这篇故事并非探讨戴利的同性恋状态,因为我们无从得知他到底是否同性恋,我们只能了解父亲的想法。极为直观的是,故事探讨的是在美国梦——白人的、中产阶级的、异性恋的——的观念中建立起评价何为家庭的绝对参数的种种偏见如何扭曲我们对现实的认知,使我们急于根据片面的、可疑的"证据"得出不可靠的结论。重要的是,休斯有时似乎爱和读者开玩笑,会故意在小说中运用明显有违常理的、幽默的细节;当这些细节被识别并解构时,会破坏它们所暗示的虚假的关于性的隐晦意义。最后,故事揭露了基于社会性别建构的偏颇观念会导致我们置身于反常的现实之中,并揭示了我们会出于某些固有成见而怀有厌恶情绪,进而得出没有依据的判断,草率行事。另外,因为约翰有着强烈渴望突显符合美国理想的家庭意象,以至于对自己的儿子形成偏见,缺乏尊重,这样,休斯的故事其实构成了对这一美国梦的控拆。

The process of various ions and molecules getting into and out of cells is critical for plant survival. The non-invasive scanning ion-selective electrode technique (SIET) is a non-invasive method to obtain the information of ions/molecules across membranes in plant. This technique can measure the absolute concentration of ions and molecules, and also their fluxes and directions of movement. The samples to be analyzed can be a single cell, a piece of tissue, a whole organ and even an intact seedling. This article reviews the recent progress made in plant physiology by using this technique and discusses its potentials in future studies on plant physiology.

关键词： non-invasive electrophysiology technique ion-selective electrode ion transport across membrane SIET.
