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...

The data focused on the value of immunofluorescence on paraffin-embedded sections are controversial, and it is still difficult to obtain reproducible results. The aim of our study was to evaluate the usefulness of immunofluorescence on paraffin-embedded renal section in detecting immune complex deposits in IgA nephropathy (n = 24), membranous glomerulopathy (n = 22) and lupus nephritis (n = 24)...

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...
