I read Dr Kern’s article on the technique of subareolar blue dye injection with great interest. I was also interested in Dr Kern’s reply to the letter by Dr Ahmad Shatila. I was particularly intrigued by the comment made by Dr Kern that the sentinel lymphatic channels provide access to the same sentinel lymph nodes that receive lymph flow from peritumoral injections, and most importantly, that ...

We study thermophysical properties of a Janus fluid with constrained orientations, using analytical techniques and numerical simulations. The Janus character is modeled by means of a Kern-Frenkel potential where each sphere has one hemisphere of square-well and the other of hard-sphere character. The orientational constraint is enforced by assuming that each hemisphere can only point either Nor...

In this paper we have presented an eecient method to identify a part of the boundary of the domain for the heat equation. We formulated the problem as Jacques Simon did in 14] and we proposed a new identiication method. The theory used for the identiication needs the sentinels method developed by Lions 9], Kern evez 7] and Bodart 3]. And nally, we got a local convergence result for the iterativ...

Brown-headed cowbirds (Molothrus ater) are obligate brood-parasites, that is, female cowbirds lay their eggs in nests of other species. If the cowbird eggs are accepted, the host pair may raise the young cowbird, often at a reduction of the hosts’ reproductive success. Cowbird females are also known to remove host eggs and nestlings from nests, which may also affect the reproductive success of ...

riculum, and culture and systems change. The Triple Aim for Medical Education parallels and complements the Triple Aim for Health Care – better care, better value, better health – and will allow the development of a new standard for medical education. A unique aspect of the Kern Institute is its collaborative framework, as it will work closely with a National Transformation Network (NTN) to ach...

The immunochemical mechanisms involved in penicillin allergy have been the subject of numerous investigations during the past 10 years. Considerable progress in understanding how patients become sensitized to penicillin has been made since the publications by Levine (1960) and Weck and Eisen (1960) on various antigenic determinants involved in contact hypersensitivity to penicillin as well as t...

We consider a system of linear inequalities and its associated polyhedron for which we can maximize any linear objective function by /nding tight inequalities at an optimal solution in a greedy way. We call such a system of inequalities a dual greedy system and its associated polyhedron a dual greedy polyhedron. Such dual greedy systems have been considered by Faigle and Kern, and Kr1 uger for ...
