On completely integrable implicit ordinary differential equations [PDF]
, 2010 For smooth explicit n-th order ordinary differential equations, there exists a unique solution with initial condition and hence exists an n-parameter family of solutions at least locally.

Advanced Materials, EarlyView.We introduce a computational workflow that combines quantum chemical calculations and machine learning techniques to predict the catalytic performance of a wide range of catalysts in the nitrogen reduction reaction (NRR). The analysis of the trained models provides insights into the complex structure–activity relationship in experimental catalytic ...

The assessment of nanofluid in a Von Karman flow with temperature relied viscosity
Results in Physics, 2018 This work endeavor to study the heat and mass transfer viscous nanofluid features in a Von Karman flow invoking the variable viscosity mechanism. Moreover, we have extended our study in view of heat generation and uniform suction effects.

Implicitization of differential rational parametric equations
Journal of Symbolic Computation, 2003 The problem of implicitization for algebraic varieties takes care of finding algorithms to get the ideal of an unirational algebraic variety from a system of parametric equations. This classical problem has been much studied in recent years with the method of Gröbner bases. Here the analogous problem is studied for differential varieties.

An Implicit Equation Given Certain Parametric Equations
Missouri Journal of Mathematical Sciences, 2006 This paper concerns finding the implicit equation of a given monomial parametrization of projective surfaces. The discussion is concentrated on the irreducibility of the equation.

On the covering dimension of the set of solutions of some nonlinear equations [PDF]
, 1986 We prove an abstract theorem whose sole hypothesis is that the degree of a certain map is nonzero and whose parametric equations are studied using cohomological mconclusions imply sharp, multidimensional continuation results.

Soft Hardware, Flowing Software: Reconfigurable Microfluidics for Adaptable Chemical Computation
Advanced Materials, EarlyView.A reconfigurable microfluidic platform based on soft, photo‐printable, and chemically erasable hydrogel structures printed and erased in situ is used to control flow routing, mixing, chemical patterning, and even chemical computing. Using hardware to control chemical computations decouples logic function from molecular composition, demonstrated via ...

Peano's Theorem for Implicit Differential Equations
Journal of Mathematical Analysis and Applications, 2001 The author proves an existence result for the Cauchy problem \[ F(t,x,x', \ldots,x^{(m)})=0,\quad x(0)=x_0,x'(0)=x_1, \ldots, x^{(m-1)}(0)=x_{m-1}, \] with \(m \in {\mathbb N}\). He looks for solutions in the Lipschitz sense and gives an example where there exist no classical solutions.
