The role of venture‐financed startups in innovation for US agriculture

American Journal of Agricultural Economics, EarlyView.
Abstract To evaluate the role played by startup companies in the innovation ecosystem of US agriculture, we compile a unique dataset of 6024 new entrants founded 1987–2019 that details their financing lifecycles, annual economic performance, and patenting activities.

THE FORMAL ASYMPTOTIC EXPANSION OF A DARCY-STOKES COUPLED SYSTEM

Revista de la Facultad de Ciencias, 2013
Using the heuristic method of formal asymptotic expansions, we analyze the order of magnitude of the diferent physical entities involved in the phenomenon of  fluid exchange between geometric regions, where the velocity of the  fluid  flow has diferent ...

Laurent Asymptotic Expansions

, 2017
In Chapter 2, we present operational rules for Laurent asymptotic expansions given in two forms, with remainders given in the standard form o(⋅ ) and with explicit power-type upper bounds for remainders.

Hybrid Inertial–Centrifugal Gas–Liquid Separator: CFD‐Driven Optimization Using Coupled Discrete Phase and Wall‐Film Modeling With Response Surface Methodology

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Efficient removal of liquid aerosols from compressed gas streams is essential in chemical and energy processes. Conventional separators relying on a single mechanism (inertial or centrifugal) struggle to capture both fine and coarse droplets simultaneously.

Residual Strength Prediction of Chemically Reactive Two‐Phase Nanofluid Flow in a Bingham–Papanastasiou Rheological Theory Using a Morlet‐Based Wavelet Neural Network Approach

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The behavior of nanofluid flow involving a zero‐mass flux condition has received considerable interest because of a realistic scenario. In reality, this condition confines the optimistic accumulation or disappearance of nanoparticles past a sheet, constructing a more physically realistic demonstration through several applications, such as heat

Asymptotic expansions and domain decomposition

, 2014
At a first glance asymptotic expansions and domain decomposition are two alternatives to efficiently solve multi scale elasticity problems. In this paper we will combine these two methods: we will use, for several types of problems, asymptotic expansions

Streamline and Isotherm Visual Analysis of Darcy–Forchheimer von Karman Spinning Flow of Maxwell Fluid Over a Stretching Disk With Quadratic Temperature‐Dependent Heat Source

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This research paper provides an extensive study of the effects of Darcy–Forchheimer von‐Karman spinning flow of Maxwell fluid across a stretching disk including the effect of heat generation based on a nonlinear function of temperature. The flow system is influenced by thermal radiations and Arrhenius activation energy.

On combined asymptotic expansions in singular perturbations

Electronic Journal of Differential Equations, 2002
A structured and synthetic presentation of Vasil'eva's combined expansions is proposed. These expansions take into account the limit layer and the slow motion of solutions of a singularly perturbed differential equation.

Time-kernel for lattice determinations of NLO hadronic vacuum polarization contributions to the muon g-2

Physics Letters B
We study the time-momentum representation of the kernel needed to compute the hadronic vacuum polarization contribution to the muon g-2 in the space-like region at next-to-leading order.
