Efficient multiplication in finite fields Fqn requires Fq-bases of low density,i.e., such that the products of the basis elements have a sparse expression in the basis. In this paper we introduce a new family of bases: the quasi-normal bases. These bases generalize the notion of normal bases and provide simple exponentiation to the power q in Fqn . For some extension fields Fqn over Fq, we cons...

In light of the shortage of healthcare professionals, many developing countries operate a de facto two-tiered system of healthcare provision, in which Community Health Workers (CHWs) supplement service provision by fully qualified physicians. CHWs are relatively inexpensive to train but can treat only a limited range of medical conditions. This paper explicitly models a two-tiered structure of ...

imagine trying to be an effective teacher at a school where the average student misses two months of class time out of nine months of the school year—a common situation in urban high schools. Further, imagine that your fellow teachers and school leaders refuse to work together to prevent students from skipping class or support struggling students in a coordinated way. You may stay, but probably...
