Tumor-induced lipid loss physically accelerates breast cancer invasion into mammary adipose tissue
Garrett F. Beeghly, Dong Wang, Bo Ri Seo +8
Obesity is a major risk factor for breast cancer, yet how obesity-associated changes in the physical properties of white adipose tissue (WAT) influence tumor invasion remains poorl…
Effect of sub-critical fluid shear flow on granular bed strength
Dong Wang, Sophie Bodek, Nicholas T. Ouellette +2
Interactions between fluids and granular materials are prevalent on the Earth's surface. In the case of fluid flow over a sediment bed, the fluid imparts a shear stress to the gran…
Preserving elastic anisotropy with tessellations of granular packings
Annie Z. Xia, Dong Wang, Catherine La Riviere +3
Multiscale periodic metamaterials have been designed for numerous applications, such as impact absorption, acoustic cloaking, photonic band gaps, and mechanical logic gates. This p…
Cell Shape Emerges from Motion
Gautham Gopinath, Emmanuel Y. Mintah, Aashrith Saraswathibhatla +6
We perform cell segmentation on images from experimental studies of confluent, mobile cells in epithelial monolayers and show that these systems possess a broad, positively-skewed…
Particle-scale origin of quadrupolar non-affine displacement fields in granular solids
Evan P. Willmarth, Weiwei Jin, Dong Wang +4
In this work, we identify the local structural defects that control the non-affine displacement fields in jammed disk packings subjected to athermal, quasistatic (AQS) simple shear…
Evolution of Adaptive Force Chains in Reconfigurable Granular Metamaterials
Sven Witthaus, Atoosa Parsa, Dong Wang +7
Under an externally applied load, granular packings form force chains that depend on the contact network and moduli of the grains. In this work, we investigate packings of variable…
Tuning the Size and Stiffness of Inflatable Particles
Nidhi Pashine, Dong Wang, Robert Baines +4
We describe size-varying cylindrical particles made from silicone elastomers that can serve as building blocks for robotic granular materials. The particle size variation, which is…
The effect of stereochemical constraints on the structural properties of folded proteins
Jack A. Logan, Jacob Sumner, Alex T. Grigas +2
Proteins are composed of chains of amino acids that fold into complex three-dimensional structures. Several key features, such as the radius of gyration, fraction of core amino aci…
Protein folding as a jamming transition
Alex T. Grigas, Zhuoyi Liu, Jack A. Logan +2
Proteins fold to a specific functional conformation with a densely packed hydrophobic core that controls their stability. We develop a geometric, yet all-atom model for proteins th…
The connection between polymer collapse and the onset of jamming
Alex T. Grigas, Aliza Fisher, Mark D. Shattuck +1
Previous studies have shown that the interiors of proteins are densely packed, reaching packing fractions that are as large as those found for static packings of individual amino-a…
Tessellated granular metamaterials with tunable elastic moduli
Nidhi Pashine, Dong Wang, Jerry Zhang +5
Most granular packings possess shear moduli () that increase with the applied external pressure, and bulk moduli () that increase or remain constant with pressure. This paper…
Designing the pressure-dependent shear modulus using tessellated granular metamaterials
Jerry Zhang, Dong Wang, Weiwei Jin +5
Jammed packings of granular materials display complex mechanical response. For example, the ensemble-averaged shear modulus increases as a power-law…

Strain-controlled isotropic compression gives rise to jammed packings of repulsive, frictionless disks with either positive or negative global shear moduli. We carry out computatio…

Numerous experimental and computational studies show that continuous hopper flows of granular materials obey the Beverloo equation that relates the volume flow rate and the ori…
