Isolated premature mammary gland enlargement, or precocious thelarche (thelarche praecox, t.p.), is a glandular tissue development which occurs in girls below eight years of age without any other symptoms of systemic estro− gen activity. T.p. is usually observed during the first two to three years of life. Ethnic and nutritional factors influ− ence the frequency of t.p. incidence. T.p. is conne...

I show that consulting two experts is better than consulting just one. In the simple “peer review” mechanism, the decision maker receives just one report, and the second expert decides whether to block the first expert’s report. A more rigid peer review proce...

the present paper investigates the advantages of a new class of composite grid structures over conventional grids. thus far, a known grid structure such as orthogrid or isogrid has been used as an orthotropic layer with at most in-plane anisotropy. the present laminated grid is composed of various numbers of thin composite grid layers. the stiffness of the structure can be adjusted by choosing ...
