From 4d Yang-Mills to 2d ℂℙN − 1 model: IR problem and confinement at weak coupling

open access: yesJournal of High Energy Physics, 2017
We study four-dimensional SU(N) Yang-Mills theory on ℝ × T 3 = ℝ × S A 1 × S B 1 × S C 1 $$ \mathbb{R}\times {\mathbb{T}}^3=\mathbb{R}\times {S}_A^1\times {S}_B^1\times {S}_C^1 $$ , with a twisted boundary condition by a ℤ N center symmetry imposed on S ...

Performance of Thromboelastography 6s Difference in Reaction Time Between Heparinase-Free and Heparinase-Containing Channel for Detecting Subtherapeutic Unfractionated Heparin Anticoagulation in a Pediatric Cardiac ICU [PDF]

open access: yesCritical Care Explorations
OBJECTIVES:. In cases where anti-Xa activity is not routinely measurable, estimating heparin efficacy using the activated partial thromboplastin time (APTT) is challenging, and misestimation may risk bleeding or thrombotic complications.
