An analysis method of analyzing a behavior of a particle system that includes a plurality of particles forming a flow field by using a renormalized molecular dynamics method, includes: performing renormalization on the particle system according to a degree of renormalization determined for each of three orthogonal directions according to a shape of the flow field; and numerically solving a motion equation governing a motion of the particle system with respect to the particle system after the renormalization, in which in the performing of renormalization, the number of particles is reduced according to the degree of renormalization, and the mass of each particle is increased according to the degree of renormalization without changing the shape and volume of the flow field before and after the renormalization, and an interaction potential between the particles is transformed according to the degree of renormalization in each of the three directions.

Lab-on-a-chip (LOC) for biomimetic bone remodeling analysis
11207676 · 2021-12-28 · ·

A lab-on-a-chip (LOC) for the biomimetic study of the multicellular interactions of bone cells includes a PDMS substrate and cap, which together form one or more wells that are fluidly coupled by tubes. The wells are configured to support various bone cells and related cellular support substrates therein, while the tubes allow conditioned medium (CM), including soluble signals, and various other co-factors to be communicated among the various wells. By controlling the configuration among and between various bone cells in the wells, the temporal and spatial limitations associated with traditional in vivo bone tissue models is removed. In addition, the LOC enables a particular research objective to be studied by allowing the user to configure the arrangement of the wells/tubes of the LOC, so as to control the manner in which bone cell soluble signals, bone cell contact, and bone cell matrix interaction interplay.
