The Reliability of Measuring Gross Efficiency During High-Intensity Cycling Exercise [PDF]

International Journal of Sports Physiology and Performance, 2020
Purpose: To evaluate the reliability of calculating gross efficiency (GE) conventionally and using a back extrapolation (BE) method during high-intensity exercise (HIE). Methods: A total of 12 trained participants completed 2 HIE bouts (P1 = 4 min at 80% maximal aerobic power [MAP]; P2 = 4 min at 100%MAP). GE was calculated conventionally in the last 3

Sobolev Gradient Flow for the Gross-Pitaevskii Eigenvalue Problem: Global Convergence and Computational Efficiency [PDF]

SIAM Journal on Numerical Analysis, 2018
We propose a new normalized Sobolev gradient flow for the Gross-Pitaevskii eigenvalue problem based on an energy inner product that depends on time through the density of the flow itself.

Output volatility and efficiency gains: evidence from Latin American gross value added

Journal of Applied Economics, 2021
Based on gross value added (GVA) shares of economic activities from 1990 to 2014, the paper shows that convex growth-instability frontiers exist for 19 Latin American countries. Numerical simulations show that in 2011, Latin America's industry portfolios
