Universality in the dynamics of vesicle translocation through a hole
Bin Zheng, Fangfu Ye, Shigeyuki Komura +1
We analyze the translocation process of a spherical vesicle, made of membrane and incompressible fluid, through a hole smaller than the vesicle size, driven by pressure difference…
Trapping Instability of an Active Particle in Steering Potential Fields
Guangle Du, Fangfu Ye, Rudolf Podgornik
A particle driven by active self-propulsion can be subject to inhomogeneous potential fields, steering its orientation and leading to confinement and eventual trapping. Analytical…
Model of metameric locomotion in active directional filaments
Guangle Du, Sunita Kumari, Fangfu Ye +1
Locomotion in segmented animals, such as annelids and myriapods (centipedes and millipedes), is generated by a coordinated movement known as metameric locomotion, which can be also…
Emergent Stripes of Active Rotors in Shear Flows
Zhiyuan Zhao, Boyi Wang, Shigeyuki Komura +3
The shear-induced self-organization of active rotors into stripy aggregates is studied by carrying out computational simulations. The rotors, modeled by monolayers of frictional sp…
Ordering of adsorbed rigid rods mediated by the Boussinesq interaction on a soft substrate
Sunita Kumari, Fangfu Ye, Rudolf Podgornik
Orientational ordering driven by mechanical distortion of soft substrates plays a major role in material transformation processes such as elastocapillarity and surface anchoring. W…
Drying Pathways of an Evaporating Soft Matter Droplet
Guangle Du, Fangfu Ye, Masao Doi +1
Micro-droplets of soft matter solutions have different morphologies upon drying, and can finally become wrinkled, buckled or cavitated particles. We investigate the morphology evol…
Modeling Multi-Cellular Dynamics Regulated by ECM-Mediated Mechanical Communication via Active Particles with Polarized Effective Attraction
Yu Zheng, Qihui Fan, Christopher Eddy +4
Collective cell migration is crucial to many physiological and pathological processes. Recent experimental studies have indicated that the active traction forces generated by migra…
Hydrogen Polarity of Interfacial Water Regulates Heterogeneous Ice Nucleation
Mingzhe Shao, Chuanbiao Zhang, Conghai Qi +4
Using all-atomic molecular dynamics(MD) simulations, we show that various substrates could induce interfacial water (IW) to form the same ice-like oxygen lattice but different hydr…
Modeling cell migration regulated by cell-ECM micromechanical coupling
Yu Zheng, Hanqing Nan, Qihui Fan +6
Cell migration in fibreous extracellular matrix (ECM) is crucial to many physiological and pathological processes such as tissue regeneration, immune response and cancer progressio…
The role of deformability in determining the structural and mechanical properties of bubbles and emulsions
Arman Boromand, Alexandra Signoriello, Janna Lowensohn +5
We perform computational studies of jammed particle packings in two dimensions undergoing isotropic compression using the well-characterized soft particle (SP) model and the deform…
Jamming of Deformable Polygons
Arman Boromand, Alexandra Signoriello, Fangfu Ye +2
There are two main classes of physics-based models for two-dimensional cellular materials: packings of repulsive disks and the vertex model. These models have several disadvantages…
Angstrom-resolution single-molecule fluorescence resonance energy transfer reveals mechanisms of DNA helicases
Wenxia Lin, Jianbing Ma, Daguan Nong +8
Single-molecule FRET is widely used to study helicases by detecting distance changes between a fluorescent donor and an acceptor anchored to overhangs of a forked DNA duplex. Howev…
Ultra-high-density local structure of liquid water
Cheng Yang, Chuanbiao Zhang, Fangfu Ye +1
The local structure of liquid water plays a key role in determining the anomalous properties of water. We run all-atom simulations for three microscopic water models, and use multi…
A tensor model for nematic phases of bent-core molecules based on molecular theory
Jie Xu, Fangfu Ye, Pingwen Zhang
We construct a tensor model for nematic phases of bent-core molecules from molecular theory. The form of free energy is determined by molecular symmetry, which includes the couplin…
Generalized Deam-Edwards Approach to the Statistical Mechanics of Randomly Crosslinked Systems
Xiangjun Xing, Bing-Sui Lu, Fangfu Ye +1
We address the statistical mechanics of randomly and permanently crosslinked networks. We develop a theoretical framework (vulcanization theory) which can be used to systematically…
Statistical physics of isotropic-genesis nematic elastomers: I. Structure and correlations at high temperatures
Bing-Sui Lu, Fangfu Ye, Xiangjun Xing +1
Isotropic-genesis nematic elastomers (IGNEs) are liquid crystalline polymers (LCPs) that have been randomly, permanently cross-linked in the high-temperature state so as to form an…
Lipid Segregation on Cylindrically and Spherically Curved Membranes
Fangfu Ye, Robin L. B. Selinger, Jonathan V. Selinger
