Micro- and macro-block factorizations for regularized saddle point systems [PDF]
, 2012 We present unique and existing micro-block and induced macro-block Crout-based factorizations for matrices from regularized saddle-point problems with semi-positive de¿nite regularization block.

On the negative coupling O(N) model in 2d at high temperature
Journal of High Energy PhysicsIn this work, I consider N-component scalar quantum field theory in two dimensions interacting with an upside-down quartic potential. Working in the large N limit, the model can be solved non-perturbatively using the saddle-point method for sufficiently ...

Energy Science &Engineering, EarlyView.This study mainly explores the instability characteristics of roadways near faults in the working face. Taking the 51104 transportation roadway of the 51104 working face in Shengxin Coal Mine as the main research object, through theoretical analysis, borehole inspection, numerical simulation and on‐site mine pressure observation, the instability ...

A DISCUSSION ON THE EXISTENCE OF THE SADDLE-POINT SOLUTION [PDF]
, 1993 We prove that there is no saddle point solution in the (1 + 1)-dimensional O(3) nonlinear sigma model with a term explicitly breaking symmetry down to O(2).

Equine Veterinary Journal, EarlyView.Abstract Background Racehorses undergo profound physiological changes with training and competition, but current biomarkers inadequately capture the complex molecular dynamics of exercise. This study aimed to identify novel plasma biomarkers of training adaptation and peak load using high‐throughput proteomics.

Equine Veterinary Journal, EarlyView.Abstract Background The molecular mechanisms underlying adaptation to physical exertion and racing stress in horses remain incompletely understood. Peripheral blood transcriptomics offers a minimally invasive method to monitor systemic responses to exercise and identify biomarkers of adaptation or overload. Objectives To evaluate transcriptomic changes

Equine Veterinary Journal, EarlyView.Abstract Background Exercise‐associated cardiac arrhythmias may contribute to poor performance and sudden cardiac death in horses. Widespread monitoring is limited by device availability and suitability for field use. Objectives To (1) compare electrocardiographic (ECG) quality from a smart textile system (Myant Skiin Equine) with a reference device ...

Computing Normalized Equilibria in Convex-Concave Games [PDF]
. This paper considers a fairly large class of noncooperative games in which strategies are jointly constrained. When what is called the Ky Fan or Nikaidô-Isoda function is convex-concave, selected Nash equilibria correspond to diagonal saddle points of ...
