Management of Preconditioned Calves and Impacts of Preconditioning

Veterinary Clinics of North America: Food Animal Practice, 2015
When studying the practice of preconditioning (PC) calves, many factors need to be examined to determine if cow-calf producers should make this investment. Factors such as average daily gain, feed efficiency, available labor, length of the PC period, genetics, and marketing options must be analyzed.

Preconditioning —a reappraisal of protection

Basic Research in Cardiology, 1996
Preconditioning has been described as the most potent form of protection against myocardial necrosis yet described (5). The protection conferred by preconditioning has been found against most of the deleterious effects induced by ischaemia and reperfusion, and in most animal models as well as in humans.

Support Theory for Preconditioning

SIAM Journal on Matrix Analysis and Applications, 2003
Summary: We present the support theory, a set of techniques for bounding extreme eigenvalues and condition numbers for matrix pencils. Our intended application of support theory is to enable proving condition number bounds for preconditioners for symmetric, positive definite systems. One key feature sets our approach apart from most other works: We use

Preconditioning Reduced Matrices

SIAM Journal on Matrix Analysis and Applications, 1996
The authors are interested in solving linear systems of the form \(Z^T GZp= d\). Systems of this form are obtained from the constraint minimization problem \[ \text{minimize}_x\;f(x)= \textstyle{{1\over 2}} x^T Gx- c^T x\quad\text{subject to } Ax= b. \] Here \(Z\) is a matrix whose columns form a basis for the kernel of \(A\).

Preconditioning Myocardium with Ischemia

Cardiovascular Drugs and Therapy, 1991
Preconditioning and stunning are the chief adaptive changes induced in myocardium by a brief episode of reversible ischemia followed by arterial reperfusion. In the dog heart, both coexist for a period of at least 20 minutes of reperfusion, but after 120 minutes of reflow, preconditioning is much diminished, while stunning remains fully developed ...

Ischemic Preconditioning of the Kidney

Bulletin of Experimental Biology and Medicine, 2021
The phenomenon of ischemic preconditioning was discovered in 1986 in experiments with the heart, and then it was observed in almost all organs, the kidneys included. This phenomenon is underlain by conditioning of the tissues with short ischemia/reperfusion cycles intended for subsequent exposure to pathological ischemia.

On preconditioning and penalized matrices

Numerical Linear Algebra with Applications, 1999
Given a symmetric positive definite matrix \(A\in \mathbb R^{n\times n}\) and a vector \(b\in \mathbb R^n\), a quadratic functional born by \(A\) and \(b\) is to be minimized on a subspace \(V\) of \(\mathbb R^n\). To get rid of constraints, a system \(Bx=b\), \(B\equiv A+\rho C^TC,\) where \(\rho >0\) and \(C\in \mathbb R^{m\times n}\), is solved on \(

Preconditioning of Optimal Transport

SIAM Journal on Scientific Computing, 2017
Summary: A preconditioning procedure is developed for the \(L_2\) and more general optimal transport problems. The procedure is based on a family of affine map pairs which transforms the original measures into two new measures that are closer to each other while preserving the optimality of solutions.

Preconditioning

American Association of Bovine Practitioners Conference Proceedings, 1971
“Condition” means to process, to prepare. “Pre” means before; before some event. “Precondition” means, in reference to cattle, going to the feedlot, to prepare them so they can best withstand the adjustment they undergo when they leave their point of origin to the feedlot.

Knowledge Preconditions for Plans

Journal of Logic and Computation, 1994
Summary: For an agent to be able to rely on a plan, he must know both that he is physically capable of carrying out the physical actions involved, and that he knows enough to carry out the plan. In this paper, we advance and discuss new definitions of `knowing enough to carry out a plan', for the case of a single agent carrying out a sequence of ...
