In constrained optimization, a field of mathematics, a barrier function is a continuous function whose value increases to infinity as its argument approaches...

allows nutrients to pass through the gut, while also maintaining a barrier function to keep potentially harmful substances (such as antigens) from leaving...

The secretion of various molecules into the lumen reinforces the barrier function on the extra-epithelial side, while a variety of immune cells provide...

self-concordant barrier is a particular self-concordant function, that is also a barrier function for a particular convex set. Self-concordant barriers are important...

barrier function used to encode the convex set. Any convex optimization problem can be transformed into minimizing (or maximizing) a linear function over...

causes the amnion to be passively attached to the chorion. The chorion functions to separate the amnion from the maternal decidua and uterus. The placenta...

CSF-brain barrier at the level of the pia mater, but only in the embryo. Similar to the blood–brain barrier, the blood–CSF barrier functions to prevent...

surrounds cells in the stratum corneum and contributes to the skin's barrier function. Corneodesmosomes (modified desmosomes) facilitate cellular adhesion...

placental development. The syncytiotrophoblast contributes to the barrier function of the placenta. The placenta grows throughout pregnancy. Development...

products to treat xerosis. Some moisturizers tend to weaken the skin barrier function, but studies on xerosis have proven that moisturizers containing humectants...

inadequate capability of holding moisture as well as an imperfect lip barrier function. The Journal of the American Academy of Dermatology performed a study...

A barrier certificate or barrier function is used to prove that a given region is forward invariant for a given ordinary differential equation or hybrid...

Schottky barrier, named after Walter H. Schottky, is a potential energy barrier for electrons formed at a metal–semiconductor junction. Schottky barriers have...

where δ(x) is the Dirac delta function. It is called a delta potential well if λ is negative, and a delta potential barrier if λ is positive. The delta...

protein C also provides much protection of endothelial barrier function. Endothelial barrier breakdown, and the corresponding increase in endothelial...

skin's barrier functions. Unlike conventional moisturizers made with humectants or emollients, MLE can restore and improve the barrier function of skin...
