Does agroecosystem management mitigate historic climate impacts on dryland winter wheat yields?

Agronomy Journal, Volume 114, Issue 6, Page 3515-3530, November/December 2022., 2022
Abstract Global studies that quantify climate effects on crop yields using top‐down spatial frameworks are invaluable for assessing generalized effects on world food supplies, yet do not contain the resolution necessary to identify local mediating effects of management. Our objectives were to identify (a) what climate factors have historically affected

Fundamentals of Non-relativistic Collisionless Shock Physics: II. Basic Equations and Models [PDF]

arXiv, 2008
This paper develops the basic sets of equations which lead to the conservation laws describing collisionless plasma shock waves. We discuss the evolution of shock waves by wave steepening, derive the Rankine-Hugoniot conditions for magnetogasdynamic shocks, discuss various analytical models of shock formation, and discuss the basic instabilities which ...

Delta shock wave interactions via wave front tracking method [PDF]

arXiv, 2009
In this paper we discuss delta shock interaction problem for a pressureless gas dynamics system with two different ways of approaching the subject. The first one is by using shadow wave solution concept. The result of two delta shock interactions is delta shock with non-constant speed in a general case. The second one is by perturbing the system with a

Wave heating from proto-neutron star convection and the core-collapse supernova explosion mechanism [PDF]

, 2020
Our understanding of the core-collapse supernova explosion mechanism is incomplete. While the favoured scenario is delayed revival of the stalled shock by neutrino heating, it is difficult to reliably compute explosion outcomes and energies, which depend

On Wave Function Representation of Particles as Shock Wave Discontinuities [PDF]

arXiv, 2015
In quantum theory particles are represented as wave packets. Shock wave analysis of quantum equations of motion shows that wave function representation in general and wave packet description in particular contains discontinuities due to a non-zero quantum force.
