Atmospheric brown clouds are mostly the result of biomass burning and fossil fuel consumption. They consist of a mixture of light-absorbing and light-scattering aerosols and therefore contribute to atmospheric solar heating and surface cooling. The sum of the two climate forcing terms-the net aerosol forcing effect-is thought to be negative and may have(More)
[1] Simple dynamical models developed for the tropical Pacific surface winds may not be directly applicable in the Atlantic in view of the basin's different geometry and size and the potential impact of deep heating from over the adjacent African and South American continents. As simple dynamical models generate surface winds from sea-surface temperature(More)
Granulomatous hypophysitis is a rare pituitary condition that commonly presents with enlargement of the pituitary gland. A 31-year-old woman was admitted to the hospital with a severe headache and bitemporal hemianopsia. Magnetic resonance imaging (MRI) showed an 18 × 10-mm sellar mass with suprasellar extension and compression of the optic chiasm.(More)
Extraction of accurate seasonal cycle in the Tropcial Paciic sea surface temperature (SST) eld is addressed as a demonstration of the utility of a new technique called the Cyclostationary Empirical Orthogonal Function (CSEOF) analysis. The strength of the seasonal cycle has uctuated roughly by 15% in the past 30 years (1970-99), and this uctuation includes(More)
High-quality N-doped graphene quantum sheets are successfully fabricated from as-grown monolayer graphene on Cu using nitrogen plasma, which can be transferred as a film-like layer or easily dispersed in an organic solvent for further optoelectronic or photoelectrochemical applications.

With the WTO trade talks deadlocked since 2008, the US and the EU are turning towards preferential trade agreements, including so-called 'mega-regionals'. But these leave out the planet's more dynamic traders – including large emerging economies such as China, India and Brazil – so such agreements can only have a relatively small positive impact. From a(More)
This paper documents that virtually all of the growth in the skilled wage premium over the 1980's in the United States was confined to metropolitan areas. Explanations for the growth in the skilled wage premium will therefore need to take location into account.
An unusual type of hypertrophic cardiomyopathy was diagnosed in a 17-year-old girl who presented with dyspnea on exertion. The hypertrophied myocardium was localized to the anterior portion of the left ventricle from the base to the apex without left ventricular outflow tract obstruction. On cardiac magnetic resonance imaging (MRI), patchy and linear(More)
