Patterns and causes of spatial and temporal variability of dust presence in the central and western Sahara by Ashpole, I

“…The central and western Sahara (CWS) is the dustiest place on Earth during the northern hemisphere summer. Understanding patterns and causes of spatial and temporal variability of dust presence here is essential for its reliable simulation in numerical models of weather and climate. …”

The severity of pandemic H1N1 influenza in the United States, April - July 2009 by Presanis, A, De Angelis, D, Hagy, A, Reed, C, Riley, S, Cooper, B, Finelli, L, Biedrzycki, P, Lipsitch, M

“…<p><strong>Background:</strong> Accurate measures of the severity of pandemic (H1N1) 2009 influenza (pH1N1) are needed to assess the likely impact of an anticipated resurgence in the autumn in the Northern Hemisphere. Severity has been difficult to measure because jurisdictions with large numbers of deaths and other severe outcomes have had too many cases to assess the total number with confidence. …”
