Acta Numerica, 2015 The computational solution of problems can be restricted by the availability of solution methods for linear(ized) systems of equations. In conjunction with iterative methods, preconditioning is often the vital component in enabling the solution of such systems when the dimension is large. We attempt a broad review of preconditioning methods.

Riemannian Preconditioning [PDF]
SIAM Journal on Optimization, 2016 This paper exploits a basic connection between sequential quadratic programming and Riemannian gradient optimization to address the general question of selecting a metric in Riemannian optimization, in particular when the Riemannian structure is sought on a quotient manifold.

Archives of Surgery, 2001 The initial discovery of cardiac preconditioning has evolved into an exciting series of practical surgical applications. An enormous amount of evidence demonstrating both the safety and efficacy of ischemic preconditioning is available from animal studies.

Spotlight on preconditioning [PDF]
Cardiovascular Research, 2002 The phenomenon of ischaemic preconditioning, in which a period of sublethal ischemia can profoundly protect the cell from subsequent lethal ischemic insult, has without doubt been responsible for an enormous amount of research over the last 15 years. Since the original publication in 1986 by Murry et al.

Preconditioning of arteriogenesis [PDF]
Cardiovascular Research, 2005 Last decade, the shear stress caused by increased blood flow in collateral circulation after occlusion of main artery was recognized as a trigger of vascular remodeling and collateral growth. The goal of this study was to differentiate whether the on-going increased blood flow is necessary for the vascular remodeling or the remodeling, once in progress,

The Mechanisms of Peripheral Nerve Preconditioning Injury on Promoting Axonal Regeneration
Neural Plasticity, 2021 Two major factors contribute to the failure of axonal regrowth in the central nervous system (CNS), namely, the neuronal intrinsic regenerative capacity and the extrinsic local inhibitory microenvironments.

Controversies in preconditioning [PDF]
Cardiovascular Drugs and Therapy, 1997 Preconditioning is an effective mean of protecting the heart against prolonged ischemia by pretreating it with a minor insult, and the present paper reviews various controversies in this highly active field of research. In many models, adenosine plays a role by triggering the activation of protein kinase C. It may work in conjunction with other agents,

iScience, 2021 Summary: The “preconditioning effect” in AKI is a phenomenon in which an episode of ischemia-reperfusion results in tolerance to subsequent ischemia-reperfusion injury. However, its relationship between DNA damage repair has not been elucidated. Here, we
