Living organisms are characterised by the performance of certain life processes or functions, which distinguish them from non-living things. Nonliving things may perform one or more of these processes, for example a crystal can grow, and a machine can move. It is only a living organism that ...
Collective motion is found at all scales in biological and artificial systems, and extensive research is devoted to describing the interplay between interactions and external cues in collective dynamics. Magnetotactic bacteria constitute a remarkable example of living organisms for which motion can be ...
There are currently more than 600 complete or near-complete genome sequences of prokaryotic organisms, which provide a huge database to explore the biochemical diversity of mechanisms by which the ΔG released during respiratory electron transfer can be transduced in a pmf. Redox loops are commonly...
Functional dependence leads to developmental dependence.The facilitation hypothesis states that the first organisms, which settle on hardened lava or sand dunes, eventually change their abiotic environment in such a way that it becomes suitable for the arrival of other species. With time, the latter ...
Living organisms have developed a multitude of timing mechanisms-- "biological clocks." Their mechanisms are based on either oscillations (oscil- latory cl... L Rensing,U Meyer-Grahle,P Ruoff - 《Chronobiology International》 被引量: 137发表: 2001年 Light and temperature cooperate to regulate ...
Macropinocytosis evolved early in evolution, probably as an uptake mechanism for nutrients in free-living organisms2. In mammalian cells, this mechanism is important in dendritic cells and macrophages which use it to sample body fluids for antigens. Macropinocytosis is exploited by pathogens, which ...
Living organisms constitute the most outstanding example of self organisation. They are truely exceptional. Several views of self organisation which have been emerging in the last few decades have provided some conceptual models (1), and have even led to experiments in order to test their applicabil...
Draft Hierarchy in lexical organisation of natural languages Words have often been compared to living organisms. One of the first authors to develop this idea was the French linguist Arsène Darmesteter who wrote in ... Bruno Gaume,Fabienne Venant,B. Victorri 被引量: 0发表: 2007年 ...
(2001) geben in ihrem Buch Self-organisation in biological systems" dankens- (und ausnahms-) weise eine klare Definition über das, wovon ein Buch handelt: Self-organization is a process in which pattern at the global level of a system emerges solely from numerous interactions among the lower...
organisms, including bacteria, yeast,Drosophila,andCaenorhabditis elegans,suggesting that lipid organisation is evolutionarily conserved. In this review, we summarise the importance and function of specific lipid domains in main cellular organelles and discuss recent advances that investigate how these ...
