Stochastic processes on graphs are a powerful tool for modeling complex dynamical systems such as epidemics. A recent line of work focused on the inference problem where one aims to estimate the state of every node at every time, starting f...
Spatially coherent oscillations in neural fields with inhibition and adaptation. II. Two-dimensional domains [0.03%]

We study the bifurcation of stationary activity bumps to localized, spatially coherent oscillations in a family of elementary neural field models involving nonlocal synaptic excitation and inhibition with Heaviside firing rate nonlinearity ...
Exact diagonalization study of energy-level statistics in harmonically confined interacting bosons [0.03%]

We present an exact diagonalization study of the spectral properties of bosons harmonically confined in a quasi-2D plane and interacting via repulsive Gaussian potential. We consider the lowest 100 energy levels for systems of N=12,16, and ...

Modern computing architectures are vastly more energy dissipative than fundamental thermodynamic limits suggest, motivating the search for principled approaches to low-dissipation logical operations. We formulate multibit logical gates (bit...
Comb polymers in dilute solutions: Analytical approach, computer simulations, and experiments [0.03%]

We analyze the universal conformational properties of comblike polymer topologies in the dilute-solution regime. To this end, we evaluate the effective radii of gyration of polymer structures across a range of parameters, including the numb...

Phylogenetic trees capture evolutionary relationships among species and reflect the forces that shaped them. While many studies rely on branch length information, the topology of phylogenetic trees--particularly their degree of imbalance--o...
Magnetically controlled double-twist director configuration of lyotropic chromonic liquid crystals in cylinders: Energetics, topological defects, and instability [0.03%]

We study experimentally how the double-twist (DT) configuration of cylindrically confined lyotropic chromonic liquid crystals (LCLCs) responds to axial magnetic fields. Our director field model unveils the energetics behind the magnetic-fie...

Dark solitons and interactions are investigated in nonlocal media under the condition of fourth-order diffraction (FOD). In the case of weak nonlocality or rectangular nonlocal response function, analytical solutions of dark solitons are ob...

Extraction of useful work from the chaotic environments remains a captivating challenge. A gear in the bath of self-propelling eccentric particles is investigated by computer simulation. We find that the asymmetrical gear can rotate in a sp...

Electric fields can modify protein-protein interactions and thereby influence phase behavior. In lysozyme-sodium thiocyanate solutions, we recently observed shifts in both the crystallization boundary and the liquid-liquid phase separation ...
