The clusters are intrinsically two-dimensional and, also, spatially rich. The mechanism behind the formation of the clusters is explained using soliton clustering theory.  ...  We introduce a new class of self-sustained states, which may exist as single solitons or form multisoliton clusters, in driven passive cylindrical microresonators.  ...  into helices, leading to transport of light along the cylinder's axis.  ...

The Fate of Iron in The Organism and Its Regulatory Pathways

Přemysl Mladěnka, Radomír Hrdina, Mojmír Hübl, Tomáš Šimůnek
2005 Acta Medica  
On contrary, the complex control of iron absorption cannot be fully explicated with present knowledge.  ...  Conclusion This review attempted to shed light on the fate of iron in the organism. Because the topic is large, it was necessary to omit willfully some important tasks.  ...  While there is quite a good knowledge of iron storage compounds, there is little familiarity concerning iron transport into mitochondria. A protein named frataxin could play some role.  ...

2005 Nuclear Physics A  
The theoretical calculations are based on a Relativistic Boltzmann-Uehling-Uhlenbeck (RBUU) transport equation including stochastic effects.  ...  We find an excellent agreement between theory and experiment in almost all the cases and, on the other hand, some limitations of the simple coalescence model.  ...  Fig.8 shows the mass distributions of Z = 3, 4 fragments at different times as indicated.  ...

2022 EPJ Web of Conferences  
We study light cluster and hypernuclei production in heavy-ion collisions from SIS to RHIC energies based on the n-body dynamical transport approach PHQMD (Parton-Hadron-Quantum-Molecular-Dynamics).  ...  The clusters are identified by the MST (Minimum Spanning Tree) or the SACA ('Simulated Annealing Cluster Algorithm') algorithm which finds the most-bound configuration of nucleons and clusters.  ...  The clusters have been observed experimentally at midrapidity from SIS up to LHC energies (cf.

The magnetic structure of sunspots and starspots

S.K. Solanki
2002 Astronomical Notes - Astronomische Nachrichten  
It is pointed out that if the properties of sunspots are extrapolated to giant spots on rapidly rotating stars then the observed signature can be at least qualitatively explained.  ...  The factor of 3-4 larger penumbral area relative to umbral area (seen for sunspots) also enhances the penumbral contribution. 5.  ...  The fact that is so large at the white-light boundary suggests that sunspots are bounded by a current sheet (Solanki & Schmidt 1993) , although the raggedness of the sunspot boundary in white-light images  ...

Coherent dynamics on hierarchical systems

Alexander Blumen, Veronika Bierbaum, Oliver Mülken
2006 Physica A: Statistical Mechanics and its Applications  
We succeed in finding a good lower bound for the (space) average of the quantum mechanical probability to be still or again at the initial site.  ...  We find that the transport depends strongly on the initial site of the excitation. For systems of sizes N<21, we find that processes which start at central sites are nearly recurrent.  ...  For instance, for N = 21, with an excitation starting at node 1, there are 6 different clusters, namely node 1 forms one cluster and the nodes {2, 3}, {4, 5}, {6, 7, 8, 9}, {10, 11, 12, 13}, and {14, ·  ...
