Ultraviolet radiation protection factors of livestock shade cloths for free‐range pigs

open access: yesVeterinary Dermatology, Volume 35, Issue 6, Page 641-651, December 2024.
Background – Protection from solar ultraviolet radiation (UVR) is paramount in light‐skinned pig breeds such as Yorkshire or Landrace to avoid sunburn. Objectives – Determination of the UVR exposure of a pig and the sun protection abilities of shade cloths with different shade rates.

Complex quadratic optimization and semidefinite programming

open access: yes, 2006
. In this paper we study the approximation algorithms for a class of discrete quadratic optimization problems in the Hermitian complex form. A special case of the problem that we study corresponds to the max-3-cut model used in a recent paper of Goemans ...
