User control over fluid simulations is a long-standing research problem in computer graphics. Applications in games and films often require recognizable creatures or objects formed from smoke, water, or flame. This paper describes a two-layer approach to the problem, in which a bulk velocity drives a particle system towards a target distribution, while simultaneously a vortex particle simulatio...

Systems with different interactions could develop the same critical behaviour due to underlying symmetry and universality. Using this principle of universality, we can embed correlations modeled on 3D Ising model into simulated data heavy-ion collisions, hiding weak signals a few inter-particle within large particle cloud. Employing point cloud network dynamical edge convolution, are able ident...

The rate and distance-dependence of association between surface-attached molecules may be determined by monitoring the motion of receptor-bearing spheres along ligand-coated surfaces in a flow chamber (Pierres et al., Proc. Natl. Acad. Sci. U.S.A. 95:9256-9261, 1998). Particle arrests reveal bond formation, and the particle-to-surface distance may be estimated from the ratio between the velocit...

nieman-pick disease type c is a rare, autosomal recessive, neurometabolic disorder associated with the accumulation of unesterified cholesterol in lysosomes and late endosomes. because of multiple organ involvement and wide range of clinical manifestations, these patients will demand multiple diagnostic and therapeutic procedures requiring anesthesia. sincepathogenesis of this disease is still ...

The measurement of vortex flows with particle-image velocimetry (PIV) is particularly susceptible to error arising from the finite mass of the tracer particles, owing to the high velocities and accelerations typically experienced. A classical model of Stokes-flow particle transport is adopted, and an approximate solution for the case of particle transport within an axisymmetric, quasi-two-dimen...

We present a meshless simulation method for multiphase fluid-particle systems using Smoothed Particle Hydrodynamics (SPH) and the Discrete Element Method (DEM). Rather than fully resolving the interstitial fluid, which is often infeasible, we use an unresolved fluid model based on the locally averaged Navier Stokes equations. A variable-h SPH formulation is used to calculate the fluid phase, wh...

Acoustic wave is a physical field that includes both scale field and vector field. Acoustic Vector Sensor (or called Combined Acoustic Vector Transducer) can pick up the information contained in both pressure and velocity fields, so it makes possible to use much more information. This paper from several sides: principle, structure and possibilities of its future applications, briefly discusses ...

Spatial and velocity statistics of heavy point-like particles in incompressible, homogeneous, and isotropic three-dimensional turbulence is studied by means of direct numerical simulations at two values of the Taylor-scale Reynolds number Reλ ∼ 200 and Reλ ∼ 400, corresponding to resolutions of 512 and 2048 grid points, respectively. Particles Stokes number values range from St ≈ 0.2 to 70. Sta...
