The endoplasmic reticulum (ER) is a network of sheetlike and tubular structures that spans much of a cell and contains molecules undergoing diffusive searches for targets, such as unfolded proteins searching for chaperones and recently fold...
Spontaneous flow in active nematics: Effects induced by annular confinement [0.03%]

Within the framework of continuum mechanics for materials with relaxation, this study investigates activity-induced laminar flow in an active nematic confined within an annular domain. Subsequent to the formulation of the problem as a nonli...

We use Langevin dynamics (LD) simulations to investigate single-file diffusion (SFD) in a dilute solution of flexible linear polymers inside a narrow tube with periodic boundary conditions (a torus). The transition from SFD, where the time ...

We study a family of lattice-gas systems defined on semiregular grids, obtained by projecting the vertices of three different geodesic icosahedra onto a spherical surface. By using couplings up to third neighbors, we explore various interac...
Demonstration of x-ray fluorescence spectroscopy as a sensitive temperature diagnostic for high-energy-density physics experiments [0.03%]
基于X射线荧光光谱的高温高密度物理实验敏感温度诊断技术演示

We present the use of x-ray fluorescence spectroscopy (XFS) to a sensitive temperature diagnostic in shocked foams at temperatures of 30-75 eV. Cobalt-doped foams were shock compressed using a planar drive at the OMEGA laser facility and ph...
Parrondo's paradox in tumor ecosystems: Adaptive therapy strategies to delay the development of drug resistance [0.03%]
帕瑞诺悖论在肿瘤生态系统中的应用：延迟药物耐药发展的适应性治疗策略

De-Ming Liu et al.
Maximum tolerated dose (MTD) and low-dose metronomic (LDM) schedules are widely used clinical strategies in cancer chemotherapy despite the fact that both approaches have inherent limitations. MTD often leads to drug resistance in tumors, w...

Until now, quasi-isodynamic magnetic fields have been the only known stellarator configurations that, at low collisionality, give small radial neoclassical transport and zero bootstrap current for arbitrary plasma profiles, the latter facil...
Modeling of the polymer phase transition from crystalline to conformationally disordered phase [0.03%]
聚合物的相变从晶态到构象无序态的理论模型研究

Vadim V Atrazhev
A physics-based analytical model describing the phase transition from crystalline to conformationally disordered (condis) crystalline phase is developed. In the model, the free energy is written as a function of temperature and the lattice ...
Polydispersity-driven dynamical differences between two- and three-dimensional supercooled liquids [0.03%]
聚集体分散性驱动的二维和三维过冷液体动力学差异

Ilian Pihlajamaa et al.
The dynamics of supercooled liquids and glasses are widely believed to be similar in two and three dimensions. However, our study challenges this assumption by showing that polydispersity-driven relaxation dynamics differ drastically across...
Triggered and spontaneous dormancy in bacteria during feast-famine cycles with stochastic antibiotic application [0.03%]
在抗生素随机应用的周期性饥饿与饱食循环中细菌休眠的诱发和自发性

Bacteria can enter dormancy triggered by stress, such as starvation. When stress is removed, a large part of the population will exhibit some lag time before regrowth. It has been observed that even under stress-free conditions that allow f...
