'Child Survival And Safe Motherhood' - The Hard Road Ahead

Taking cognisance of the prevailing high maternal and child mortality in the country, India's latest (Eighth) Five Year Plan has adopted an ambitious programme for 'Child Survival and Safe Motherhood (CSSM)'. The major objectives of this programme are the reduction of IMR to 50, underfive mortality to 70, maternal mortality t~ 200, and crude birth rate (CBR) to nine. The targets for service-cov...

Vertex Bisection is Hard, too

We settle an open problem mentioned in Diaz, Petit, and Serna: A survey of graph layout problems (ACM Computing Surveys 34:313–356, 2002). Of eight objectives considered in that survey, only the complexity status of minimum vertex bisection is listed as unknown. We show that both minimum and maximum vertex bisection are NP-hard, but polynomially solvable on special graph classes such as hypercu...

the algorithm for solving the inverse numerical range problem

برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.

Too hard to face.

While the Holocaust is often placed at the genesis of bioethics, this relatively young field has not yet seriously explored the conduct of German scientists and physicians involved in the human subjects experiments of the Holocaust. We comfort ourselves with the beliefs that the individuals involved in the events of the Holocaust were mad or evil and unlike other scientists and physicians. Yet ...
