We present a numerical study, based on the lattice Boltzmann method, of nematic liquid crystals flowing in microfluidic channels. We show that disclination lines are generated by the interaction between flow and anchoring conditions of the ...

In an increasingly interconnected world, understanding congestion-related phenomena in transportation and their underlying mechanisms is crucial for improving efficiency. As the transportation system becomes denser, different modes of trans...

Fractal features of permeable (e.g., porous or/and fractured) medium strongly affect the imbibition behavior in the Lucas-Washburn-like scaling regime. Mapping a spontaneous imbibition in a fractally permeable medium onto a fractal continuu...
Universal trade-off between irreversibility and intrinsic timescale in thermal relaxation with applications to thermodynamic inference [0.03%]
热力学推理中的普遍权衡：不可逆性和内在时间尺度在热弛豫中

We establish a general lower bound for the entropy production rate (EPR) based on the Kullback-Leibler divergence and the logarithmic-Sobolev constant that characterizes the timescale of relaxation. This bound can be considered as an enhanc...
Construction of digital realizations of anisotropic hyperuniform continuous random fields in two and three dimensions via generalized spectral filtering [0.03%]

Hyperuniform continuous random fields suppress large-scale fluctuations while preserving rich local disorder, making them highly attractive for next-generation photonic, thermal, and mechanical materials. However, traditional construction t...

Polar regions are covered by sea ice, which can be seen as a thin solid elastic sheet with heterogeneous mechanical properties. The dynamics of deformation of a floating solid sheet is primarily governed by gravity, water density, and the f...
Linear scaling of entropy versus energy in human brain activity, the Hagedorn temperature, and the Zipf law [0.03%]

It is well established that the brain spontaneously traverses through a very large number of states. Nevertheless, despite its relevance to understanding brain function, a formal description of this phenomenon is still lacking. To this end,...
Eastward transients in the dayside ionosphere. II. A parallel-plate capacitorlike effect [0.03%]

During the 23 April 2023 geospace storm, we observed chorus-wave-driven, energetic particle precipitation on closed magnetic field lines in the dayside magnetosphere. Simultaneously and in the ionosphere's bottom side, we observed signature...

At night in Earth's polar regions, energetic aurorae frequently penetrate into the atmosphere, with the peculiar effect of driving turbulent electrojet currents in the bottomside ionosphere. During the day, however, Earth's plasma environme...
Resonant excitation of plasma wakefields with a train of relativistic particle bunches [0.03%]

Resonances play a crucial role in media sustaining oscillatory phenomena, such as plasmas. We show with experimental results and numerical simulations that the wakefields driven by individual successive bunches in overdense plasma superpose...
