the term riga-fede disease has been used to describe chronic traumatic ulceration that occurs on the ventral surface of the tongue by natal and neonatal teeth in infants. it is important to diagnose the lesion and treat it by eliminating the source of trauma. in this case report, the neonatal tooth was extracted and after 2 weeks the lesion was resolved and the baby was feeding well.in addition...

BACKGROUND AND PURPOSE Policy makers require evidence on the costs and outcomes of different ways of organizing stroke care. This study compared the costs and survival of different ways of providing stroke care. METHODS Hospitalized stroke patients from 13 European centers were included, with demographic, case-mix, and resource use variables measured for each patient. Unit costs were collecte...

Wide differences in labor productivity are observed between agriculture and industry in most developing countries. Research suggests that these differences – often denoted a “dual economy” effect – can explain a significant portion of low output per capita levels in these countries. A central input to the labor productivity calculation is the aggregate labor effort in the agricultural sector. U...

Warm-up. It is an easy exercise to prove that for all A we have RigA(r) ≤ (n− r)2. This is nearly tight by a direct counting argument: Valiant [Val77, Theorem 6.4] proves that RigA(r) is at least about (n− r)2/ log n for a random A (and all fields F). This shows that rigid matrices exist in great numbers—however, as always, the challenge is to exhibit an explicit such matrix. Currently, the bes...

The 0/1 Multiple Knapsack Problem is an important class of combinatorial optimization problems, and various heuristic and exact methods have been devised to solve it. Genetic Algorithm (GA) shows good performance on solving static optimization problems. However, sometimes lost of diversity makes GA fail adapt to dynamic environments where evaluation function and/or constraints or environmental ...
