Nested separatrices in simple shear flows: the effect of localized disturbances on stagnation lines [PDF]
, 2005 The effects of localized two-dimensional disturbances on the structure of shear flows featuring a stagnation line are investigated. A simple superposition of a planar Couette flow and Moffatt's [J. Fluid Mech.

The effect planting hole size and manure on vegetative growth of golden teak (Tectona grandis L.)
Journal of Degraded and Mining Lands Management, 2018 Cultivation of the golden teak (Tectona grandis L.) requires the planting hole size and appropriate use of manure. The size of planting hole provides plant growth, so that the plant can grow with optimum and appropriate use of manure to provide nutrients

A Model of Secular Stagnation: Theory and Quantitative Evaluation
American Economic Journal: Macroeconomics, 2017 This paper formalizes and quantifies the secular stagnation hypothesis, defined as a persistently low or negative natural rate of interest leading to a chronically binding zero lower bound (ZLB).

Angewandte Chemie, Volume 134, Issue 51, December 19, 2022., 2022 Reactions between the highly strained uranacycle I with various boranes afford unprecedented uranium complexes bearing either a pendant borate or a pendant borane Lewis acid. The latter promotes the 1,2‐insertion of CO into a UIV‐N bond. Abstract In this contribution, we illustrate uranium complexes bearing a pendant borate (i.e.

A New Modified Firefly Algorithm for Optimizing a Supply Chain Network Problem
Applied Sciences, 2018 Firefly algorithm is among the nature-inspired optimization algorithms. The standard firefly algorithm has been successfully applied to many engineering problems. However, this algorithm might be stuck in stagnation (the solutions do not enhance anymore)

Differential Evolution Algorithm With Tracking Mechanism and Backtracking Mechanism
IEEE Access, 2018 Differential evolution (DE) is a simple and effective evolutionary algorithm that can be used to solve various optimization problems. In general, the population of DE tends to fall into stagnation or premature convergence so that it is unable to converge

Stagnation Hugoniot Analysis for Steady Combustion Waves in Propulsion Systems [PDF]
, 2006 The combustion mode in a steady-flow propulsion system has a strong influence on the overall efficiency of the system. To evaluate the relative merits of different modes, we propose that it is most appropriate to keep the upstream stagnation state fixed ...
