Probing the coverage of nanoparticles by biomimetic membranes through nanoplasmonics
Jacopo Cardellini, Andrea Ridolfi, Melissa Donati +8
Although promising for biomedicine, the clinical translation of inorganic nanoparticles (NPs) is limited by low biocompatibility and stability in biological fluids. A common strate…
Protein-polysaccharide interactions and aggregates in food formulations
Luigi Gentile
The protein-polysaccharide combinations that lead to electrostatic complex and coacervates formation are the object of extensive research using both layer-by-layer and mixed emulsi…
Ferrihydrite nanoparticles entrapped in shear-induced multilamellar vesicles
Luigi Gentile
Hypothesis Ferrihydrite (Fh) nanoparticles are receiving considerable scientific interest due to their large reactive surface areas, crystalline structures, and nanoparticle morpho…
Serum protein resistant behavior of multisite-bound poly(ethylene glycol) chains onto iron oxide surfaces
Nicoletta Giamblanco, Giovanni Marletta, Alain Graillot +3
Recent surveys have shown that the number of nanoparticle-based formulations actually used at the clinical level is significantly lower than expected a decade ago. One reason for t…
Synchronization and long-time memory in neural networks with inhibitory hubs and synaptic plasticity
Elena Bertolotti, Raffaella Burioni, Matteo di Volo +1
We investigate the dynamical role of inhibitory and highly connected nodes (hub) in synchronization and input processing of leaky-integrate-and-fire neural networks with short term…
Heterogeneous Mean Field for neural networks with short term plasticity
Matteo di Volo, Raffaella Burioni, Mario Casartelli +2
We report about the main dynamical features of a model of leaky-integrate-and fire excitatory neurons with short term plasticity defined on random massive networks. We investigate…
A microscopic mechanism for self-organized quasi periodicity in random networks of non linear oscillators
Raffaella Burioni, Serena Di Santo, Matteo di Volo +1
Self-organized quasi periodicity is one of the most puzzling dynamical phases observed in systems of non linear coupled oscillators. The single dynamical units are not locked to th…
Collective dynamics in sparse networks
Stefano Luccioli, Simona Olmi, Antonio Politi +1
The microscopic and macroscopic dynamics of random networks is investigated in the strong-dilution limit (i.e. for sparse networks). By simulating chaotic maps, Stuart-Landau oscil…
Caloric curve of star clusters
Lapo Casetti, Cesare Nardini
Self-gravitating systems, like globular clusters or elliptical galaxies, are the prototypes of many-body systems with long-range interactions, and should be the natural arena where…
Discrete Breathers in a Realistic Coarse-Grained Model of Proteins
S. Luccioli, A. Imparato, S. Lepri +2
We report the results of molecular dynamics simulations of an off-lattice protein model featuring a physical force-field and amino-acid sequence. We show that localized modes of no…
Analytical results on the magnetization of the Hamiltonian Mean Field model
Romain Bachelard, Cristel Chandre, Antonia Ciani +2
The violent relaxation and the metastable states of the Hamiltonian Mean-Field model, a paradigmatic system of long-range interactions, is studied using a Hamiltonian formalism. Ri…
Stability of splay states in globally coupled rotators
Massimo Calamai, Antonio Politi, Alessandro Torcini
The stability of dynamical states characterized by a uniform firing rate ({\it splay states}) is analyzed in a network of globally pulse-coupled rotators (neurons) subject to a…
Out of Equilibrium Solutions in the -Hamiltonian Mean Field model
Xavier Leoncini, Tineke L. Van Den Berg, Duccio Fanelli
Out of equilibrium magnetised solutions of the -Hamiltonian Mean Field (-HMF) model are build using an ensemble of integrable uncoupled pendula. Using these solutions we di…
Stability of the splay state in pulse--coupled networks
Rüdiger Zillmer, Roberto Livi, Antonio Politi +1
The stability of the dynamical states characterized by a uniform firing rate ({\it splay states}) is analyzed in a network of globally coupled leaky integrate-and-fire neurons. Thi…
Desynchronized stable states in diluted neural networks
Ruediger Zillmer, Roberto Livi, Antonio Politi +1
The dynamical properties of a diluted fully-inhibitory network of pulse-coupled neurons are investigated. Depending on the coupling strength, two different phases can be observed.…
Contact processes with long-range interactions
F. Ginelli, H. Hinrichsen, R. Livi +2
A class of non-local contact processes is introduced and studied using mean-field approximation and numerical simulations. In these processes particles are created at a rate which…
Observation of Fragile-to-Strong Dynamic Crossover in Protein Hydration Water
Sow-Hsin Chen, Li Liu, Emiliano Fratini +3
At low temperatures proteins exist in a glassy state, a state which has no conformational flexibility and shows no biological functions. In a hydrated protein, at and above 220 K,…
Desynchronization in diluted neural networks
R. Zillmer, R. Livi, A. Politi +1
The dynamical behaviour of a weakly diluted fully-inhibitory network of pulse-coupled spiking neurons is investigated. Upon increasing the coupling strength, a transition from regu…
Exploring the energy landscape of model proteins: a metric criterion for the determination of dynamical connectivity
Lorenzo Bongini, Roberto Livi, Antonio Politi +1
A method to reconstruct the energy landscape of small peptides is presented with reference to a 2d off--lattice model. The starting point is a statistical analysis of the configura…
