Machine learning, however popular and accessible, is computationally intensive and highly power-consuming, prompting interest in alternative physical implementations of learning tasks. We introduce a training scheme for physical systems tha...
Scale-free points-of-interest distribution in a city emerging from homogeneous Poissonian-point processes [0.03%]
Eleonora Andreotti,Ulysse Marquis,Maurizio Napolitano et al.
Eleonora Andreotti et al.
Urban systems often exhibit scale-invariant properties, with power-law distributions observed in various spatial and temporal patterns of human behavior. A prominent example is the distribution of commercial activities and other points of i...

The collective frequency that emerges from synchronized neuronal populations-the network resonance-shows a systematic relationship with brain size: a whole-brain large network oscillates slowly, whereas finer parcellations of fixed volume e...

V Adami et al.
We propose a paradigm for modeling real-world scale-free networks, where the integration of new nodes is driven by the combined attractiveness of degree and betweenness centralities, the competition of which (expressed by a parameter 0≤p≤...
Susceptibility for extremely low external fluctuations and critical behavior of Greenberg-Hastings neuronal model [0.03%]
Joaquin Almeira,Daniel A Martin,Dante R Chialvo et al.
Joaquin Almeira et al.
We consider the scaling behavior of the fluctuation susceptibility associated with the average activation in the Greenberg-Hastings neural network model and its relation to microscopic spontaneous activation. We found that, as the spontaneo...
Injection and acceleration of electrons by radially polarized laser pulses in a plasma channel [0.03%]
P Hadjisolomou,P Valenta,R Shaisultanov et al.
P Hadjisolomou et al.
We consider injection and subsequent acceleration of electrons in narrow plasma channels irradiated by linearly and radially polarized ultraintense laser pulses. Using three-dimensional particle-in-cell simulations, we show that radially po...
Molecular dynamics simulation on current-voltage characteristics of room temperature ionic liquids under strong electric field [0.03%]
Yufeng Cheng,Alberto T Pérez,Weizong Wang et al.
Yufeng Cheng et al.
In this work, molecular-dynamics simulations were performed on the ionic liquid 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([BMIM][TFSI]) to investigate the influence of external electric fields on the ion-transport prope...
Ultraintense half-cycle zeptosecond pulse generation via cascaded coherent wakefield synchrotron emission [0.03%]
Ze Chen,Yunliang Wang,Lipan Qin et al.
Ze Chen et al.
We report a unique regime for generating zeptosecond pulses (ZPs) to break the attosecond timescale barrier through cascaded coherent synchrotron emission driven by ultraintense x-ray laser-pulse-excited wakefields in foil. When an x-ray la...

Based on extensive parallel-tempering Monte Carlo simulations, we investigate the relationship between cluster percolation and equilibrium ordering phenomena in the three-dimensional ±J random-bond Ising model for different fractions of an...

Feedback cooling enables a system to achieve low temperatures through measurement-based control. Determining the thermodynamic cost required to achieve the ideal cooling efficiency within a finite time remains an important problem. In this ...
