Clusters of Cavity Solitons Bounded by Conical Radiation
2018

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. ...

The Fate of Iron in The Organism and Its Regulatory Pathways
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. ...

Nucleation in physical and nonphysical systems
2003
Atmospheric research
We investigate the well-known example of condensation (formation of liquid droplets) in an undercooled vapour to conclude that the formation of bound states as a phase transition is related to transportation ...
Depending on the system under consideration and its control parameters, the cluster formation in a supersaturated (metastable or unstable) situation has been observed in nucleation physics as well as in ...
The relaxation to a one-big-cluster-state as the equilibrium situation is a searching process on the energy landscape to find a minimum in a very high dimensional situation. 4. ...

Fragment formation in central heavy ion collisions at relativistic energies
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. ...

Dynamical cluster and hypernuclei production in heavy-ion collisions
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. [1] [2] [3] [4] [5] [6] ). ...

The network of the Italian stock market during the 2008–2011 financial crises

We find a general contraction of the network during the crises, both numerically due to stronger correlation as well as topologically, with the appearance of central dominant companies which attract the ...
From the degrees' distribution, we immediately observe that during the crises the number of degree 1 nodes increases from 113 to 134, consequently reducing the amount of 2, 3, 4 and 5-degree nodes, as ...

The magnetic structure of sunspots and starspots
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
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, · ...
