The renaissance of barrier methods [PDF]
Journal of Family Planning and Reproductive Health Care, 2012 In 1987, the threat of litigation led to the withdrawal of intrauterine devices (IUDs)from the American market where depot medroxyprogesterone acetate (DMPA)had already been banned. There were fears of repercussions that would have led to the limiting of contraceptive choice in Britain.

Na+/K+-ATPase α1 identified as an abundant protein in the blood-labyrinth barrier that plays an essential role in the barrier integrity. [PDF]
PLoS ONE, 2011 BACKGROUND:The endothelial-blood/tissue barrier is critical for maintaining tissue homeostasis. The ear harbors a unique endothelial-blood/tissue barrier which we term "blood-labyrinth-barrier".

Barrier subgradient method [PDF]
Mathematical Programming, 2010 The author focusses on a class of problems of minimizing a nonsmooth convex function over a feasible set endowed by a self-concordant barrier. After studying the smoothing of the support function of a convex set by a self-concordant barrier, the author describes the corresponding barrier subgradient method (BSM).

Logarithmic Barrier Method Via Minorant Function for Linear Semidefinite Programming
Annales Mathematicae Silesianae, 2023 We propose in this study, a new logarithmic barrier approach to solve linear semidefinite programming problem. We are interested in computation of the direction by Newton’s method and of the displacement step using minorant functions instead of line ...
