While the formation of the lamellipodium is increasingly well understood, organizational principles underlying the emergence of the lamellum are just beginning to be unraveled. We report here on a 1D mathematical model which describes the reaction-diffusion processes of a polarized actin network in steady state, and reproduces essential characteristics of the lamellipodium-lamellum system. We observe a steep gradient in filament lengths at the protruding edge, a local depolymerization maximum a few microns behind the edge, as well as a differential dominance of the network destabilizer ADF/cofilin and the stabilizer tropomyosin. We identify simple and robust organizational principles giving rise to the derived network characteristics, uncoupled from the specifics of any molecular implementation, and thus plausibly valid across cell types. An analysis of network length dependence on physico-chemical system parameters implies that to limit array treadmilling to cellular dimensions, network growth has to be truncated by mechanisms other than aging-induced depolymerization, e.g., by myosin-associated network dissociation at the transition to the cell body. Our work contributes to the analytical understanding of the cytoskeletal extension's bisection into lamellipodium and lamellum and sheds light on how cells organize their molecular machinery to achieve motility.}, language = {en} } @article{HuberKaes2011, author = {Huber, Florian and K{\"a}s, Josef}, title = {Self-regulative organization of the cytoskeleton}, series = {Cytoskeleton}, volume = {68}, journal = {Cytoskeleton}, number = {5}, publisher = {Wiley}, issn = {1949-3592}, doi = {10.1002/cm.20509}, pages = {259 -- 265}, year = {2011}, abstract = {Despite its impressive complexity the cytoskeleton succeeds to persistently organize itself and thus the cells' interior. In contrast to classical man-made machines, much of the cellular organization originates from inherent self-assembly and self-organization allowing a high degree of autonomy for various functional units. Recent experimental and theoretical studies revealed numerous examples of cytoskeleton components that arrange and organize in a self-regulative way. In the present review we want to shortly summarize some of the principle mechanisms that are able to inherently trigger and regulate the cytoskeleton organization. Although taken individually most of these regulative principles are rather simple with intuitively predictable consequences, combinations of two or more of these mechanisms can quickly give rise to very complex, unexpected behavior and might even be able to explain the formation of different functional units out of a common pool of available building blocks.}, language = {en} } @article{MeiSanchezReineckeetal.2011, author = {Mei, Bastian and S{\´a}nchez, Miguel D. and Reinecke, Thomas and Kaluza, Stefan and Xia, Wei and Muhler, Martin}, title = {The synthesis of Nb-doped TiO2 nanoparticles by spray drying: an efficient and scalable method}, series = {Journal of Materials Chemistry}, volume = {21}, journal = {Journal of Materials Chemistry}, number = {32}, publisher = {Royal Society of Chemistry (RSC)}, issn = {1364-5501}, doi = {10.1039/c1jm11431j}, pages = {11781 -- 11790}, year = {2011}, language = {en} } @article{KaluzaBehrensSchiefenhoeveletal.2011, author = {Kaluza, Stefan and Behrens, Malte and Schiefenh{\"o}vel, Nora and Kniep, Benjamin and Fischer, Richard and Schl{\"o}gl, Robert and Muhler, Martin}, title = {A Novel Synthesis Route for Cu/ZnO/Al2O3 Catalysts used in Methanol Synthesis: Combining Continuous Consecutive Precipitation with Continuous Aging of the Precipitate}, series = {ChemCatChem}, volume = {3}, journal = {ChemCatChem}, number = {1}, publisher = {Wiley}, issn = {1867-3899}, doi = {10.1002/cctc.201000329}, pages = {189 -- 199}, year = {2011}, language = {en} } @article{ScherpSaathoffFranzetal.2011, author = {Scherp, Ansgar and Saathoff, Carsten and Franz, Thomas and Staab, Steffen}, title = {Designing core ontologies}, series = {Applied Ontology}, volume = {6}, journal = {Applied Ontology}, number = {3}, publisher = {IOS Press}, issn = {1875-8533}, doi = {10.3233/AO-2011-0096}, pages = {177 -- 221}, year = {2011}, language = {de} } @article{Haeusler2011, author = {H{\"a}usler, Alexander}, title = {Die „PRO-Bewegung" und der antimuslimische Kulturrassismus von Rechtsaußen}, series = {Expertisen f{\"u}r Demokratie}, journal = {Expertisen f{\"u}r Demokratie}, publisher = {Friedrich-Ebert-Stiftung, Forum Berlin}, address = {Berlin}, year = {2011}, language = {de} } @article{JoedickeJoedicke2011, author = {J{\"o}dicke, Dirk and J{\"o}dicke, Ralf}, title = {Anwendung des Aktivierungs- und Saldierungswahlrechts latenter Steuern und Differenzierung nach Ergebniswirksamkeit}, series = {KoR: Zeitschrift f{\"u}r internationale und kapitalmarktorientierte Rechnungslegung}, volume = {11}, journal = {KoR: Zeitschrift f{\"u}r internationale und kapitalmarktorientierte Rechnungslegung}, number = {3}, publisher = {Handelsblatt Fachmedien}, issn = {1617-8084}, pages = {153 -- 160}, year = {2011}, language = {de} } @article{YangKollmannsbergerDuesteretal.2011, author = {Yang, Zhengxiong and Kollmannsberger, Stefan and D{\"u}ster, Alexander and Ruess, Martin and Garcia, Eduardo Grande and Burgkart, Rainer and Rank, Ernst}, title = {Non-standard bone simulation: interactive numerical analysis by computational steering}, series = {Computing and Visualization in Science}, volume = {14}, journal = {Computing and Visualization in Science}, number = {5}, publisher = {Springer}, doi = {10.1007/s00791-012-0175-y}, pages = {207 -- 216}, year = {2011}, language = {en} } @article{EliassonPalssonWeber2011, author = {El{\´i}asson, J{\´o}nas and Palsson, Asgeir and Weber, Konradin}, title = {Monitoring ash clouds for aviation}, series = {Nature}, volume = {475}, journal = {Nature}, number = {7357}, publisher = {Springer Nature}, doi = {10.1038/475455b}, pages = {455}, year = {2011}, language = {en} }
