The formation of pairs and trains particles in inertial microfluidics is an important consideration for device design applications, such as particle focusing separation. We study the stability linear staggered nearly rigid spherical different sizes a pressure-driven flow through straight duct with rectangular cross section under mild inertia. An in-house lattice-Boltzmann-immersed-boundary-fini...

Stirring rates in heterogeneous catalytic reactions have an effect on reaction rates. When conducting small-scale surveys using a single central stir plate, reaction vessels in different positions experience slightly levels and patterns of agitation. We probed this by running the same 40 times, varying rate (fast/slow) and vial position two 3D printed holders. found variability conversion (meas...

Direct numerical simulation of diffusion through heterogeneous media can be difficult due to the computational cost resolving fine-scale heterogeneities. One method overcome this difficulty is homogenize model by replacing spatially-varying diffusivity with an effective calculated from solution appropriate boundary value problem. In paper, we present a new semi-analytical for solving problem an...

We characterize asymptotic collective behavior of rectangular random matrices, the sizes of which tend to infinity at different rates. It appears that one can compute the limits of all non commutative moments (thus all spectral properties) of the random matrices we consider because, when embedded in a space of larger square matrices, independent rectangular random matrices are asymptotically fr...

2. MAIN RESULTS In this paper, subdivision methods for rectangular Bézier A rectangular Bézier surface of degree n 3 m can be surfaces are generalized to subdivide a rectangular Bézier surface patch of degree n 3 m into two rectangular Bézier surrepresented by face patches of degree n 3 (m 1 n), while the parameter domain of the Bézier surface is decomposed into two trapezoids. As an applicatio...

We introduce a new class of game forms called effectively rectangular game forms. An effectively rectangular game form is one that has the same effectivity function as some rectangular game form. Actually we extend this class a little more: we define a superdeterminate game form as one that has an effectivity function which is finer than that of a rectangular game form. We prove that a tightly ...

Amaranth dye is an organic compound largely used in the food and beverage industries with potential toxicity effects on humans. In this paper, a new electrochemical sensor for determination of amaranth foods was reported, where kind V2O5 nanoplate (V2O5-NPs) employed as electrode modifying materials. The modified enhanced its signal obviously exhibited wider linear response ranging from 0.1-270...
