We utilize recent NuSTAR observations (co-added depth $\approx55$-120 ks) of PG $1001+054$, $1254+047$, and PHL 1811 to constrain their hard X-ray ($\gtrsim5$ keV) weakness spectral shapes, thus investigate the nature extreme weakness. These quasars showed very weak soft emission, they were proposed be intrinsically weak, with coronae producing continuum emission relative optical/UV emission. H...

This paper investigates whether exporting generates positive productivity spillover effects on other plants operating in the same industry and whether exporting affects productivity of plants in vertically related industries. Using plant-level data from Chile we find that exporters improve productivity of their local suppliers but not of plants that purchase intermediate inputs from them. We al...

Results: Over a mean follow-up period of 13 years, 159 persons developed dementia (including 125 with AD). After adjustment for other risk factors, only adiponectin in women was associated with an increased risk of all-cause dementia (hazard ratio [HR], 1.29; 95% confidence interval [CI], 1.00-1.66; P=.054) and AD (HR, 1.33; 95% CI, 1.00-1.76; P=.050) per 1-SD increase in adiponectin level.
