A fundamental challenge in neuroscience is to understand how biologically salient motor behaviors emerge from properties of the underlying neural circuits. Crayfish, krill, prawns, lobsters, and other long-tailed crustaceans swim by rhythmically moving limbs called swimmerets. Over entire biological range animal size paddling frequency, movements adjacent swimmerets maintain an approximate quarter-period phase difference with more posterior leading cycle. We use a computational fluid...
We present a fourth-order accurate algorithm for solving Poisson's equation, the heat and advection-diffusion equation on hierarchy of block-structured, adaptively refined grids. For spatial discretization, finite-volume stencils are derived divergence operator Laplacian in context structured adaptive mesh refinement variety boundary conditions; resulting linear system is solved with multigrid algorithm. time integration, we couple elliptic solver to Runge–Kutta method, introduced by Kennedy...
Abstract Dielectric elastomer actuators with high energy and power output, combined without pre‐stretching treatment to simplify device fabrication, are highly desirable for soft robotics. Here, different from most studies that focus on modifying elastomers such as polyacrylates silicones, the study designs a prestretch‐free dielectric based hydrogenated carboxylated nitrile butadiene rubber reach record‐high density (564 J kg −1 ) (5641 W ), ≈15 times greater than natural muscle three...
Volume-of-fluid (VOF) methods are widely-used for the interface tracking problem, yet rigorous analyses of them rare. This paper presents such an analysis incompressible flows by combining theories ordinary differential equations, geometry, and Boolean algebra. Based on concept donating region (DR) [Q. Zhang, SIAM Rev., 55 (2013), pp. 443--461], author classifies fluxing particles a fixed control volume into four categories derives three analytical solutions advection equation color...
The pollution status of crops planted in Guizhou province Southwestern China with high background values Fluorine (F) and Cadmium (Cd) has attracted people's concern. present study aimed to investigate the spatial distributions F Cd rice, corn wheat grains, further evaluate their health risks residents province. contents were measured by fluoride ion-selective electrode inductively coupled plasma mass spectrometry (ICP-MS) methods, respectively. Additionally, inverse distance weighted (IDW)...
Abstract Biochar (BC) and biodegradable mulch film (BMF) are both commonly used means of production in agriculture. In recent years, most studies have focused on the effects BC or BMF soil heavy metal pollution, while they neglected combined effects. this study, a pot experiment was conducted to examine impacts BMF, BC, (CMB) mobility chromium (Cr) agronomic characteristics flue-cured tobacco. Compared with control, CMB significantly reduced concentrations diethylenetriamine pentaacetic acid...
As a sequel to our previous work [Q. Zhang, SIAM J. Numer. Anal., 51 (2013), pp. 2822--2850], Zhang and A. Fogelson, Sci. Comput., 36 (2014), A2369--A2400], this paper presents MARS, generic framework for analyzing interface tracking (IT) methods via mapping adjusting regular semialgebraic sets. Our mathematical model moving material regions is the metric space of bounded semianalytic sets, equipped with Boolean algebras advected by homeomorphic flow maps nonautonomous ordinary differential...
We present an improved PAM (iPAM) method as the first fourth-order interface tracking whose convergence rates are independent of $C^1$ (derivative) discontinuities interface. As version polygonal area mapping (PAM) [Q. Zhang and P. L.-F. Liu, J. Comput. Phys., 227 (2008), pp. 4063--4088], accuracy iPAM is achieved via (i) augmenting abstract data structure to faithfully represent multiple components material regions within a single cell, (ii) removing restrictive assumptions PAM, (iii)...
Hexaconazole (Hex) has been widely used in agricultural products, and its residues may pose a potential risk to human health. However, the metabolic behavior of Hex enantiomers mammal organisms is still unknown, which important for evaluating differences their toxicity. In this study, distribution S-(+)- R-(-)-Hex mice was detected by an ultra-high performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS), mechanism toxicokinetic were analyzed molecular docking....
