November 14, 2014, will be marked forever in the history of Brazil as the day that the national medicine lost one of its greatest references: cardiologist Adib Jatene. Born in Xapuri, Acre, son of a Lebanese rubber tapper, he wrote one of the finest chapters in the history of Brazilian medicine. With a medical degree from University of São Paulo’s Faculty of Medicine (FMUSP), awarded in 1953, w...

The frequency and intensity of natural disasters have been increasing significantly over the past decades and this trend is predicted to continue. Natural disasters have a dramatic impact on human lives and on the socio-economic welfare of entire regions. They were identified in 2011 by the World Bank [The World Bank, 2011] as one of the major risks of the East Asia and Pacific region, which re...

Many different compound semiconductors can be formed by changing the combination of constituent elements. Properties of alloy semiconductors composed of a plurality of compound semiconductors can be changed in a continuous fashion by changing the composition ratio. A very thin alloy semiconductor multilayer showing interesting properties can be formed by sophisticated epitaxial growth methods s...

People increasingly use social media to get first-hand news and information. During disasters such as Hurricane Sandy and the tsunami in Japan people used social media to report injuries as well as send out their requests. During social movements such as Occupy Wall Street (OWS) and the Arab Spring, people extensively used social media to organize their events and spread the news. As more peopl...

Hurricane Sandy was one of the deadliest and costliest of hurricanes over the past few decades. Many states experienced significant power outage, however many people used social media to communicate while having limited or no access to traditional information sources. In this study, we explored the evolution of various communication patterns using machine learning techniques and determined user...

Projected impacts of climate change on human health are immense, and mitigating these impacts will require a large-scale concerted effort involving various global organisations. A recent report by University College London (Costello et al. 2009; Lancet 373: 1693–1733) has produced a comprehensive list of climate change impacts on human health. This article highlights some of the adverse impacts...

Localized plasmonic structured illumination microscopy (LPSIM) is a recently developed super resolution technique that demonstrates immense potential via arrays of localized plasmonic antennas. Microlens microscopy represents another distinct approach for improving resolution by introducing a spherical lens with a large refractive index to boost the effective numerical aperture of the imaging s...

Cancer in terms of its origin was still a mystery. It has multiple etiologic factors, including ineffectiveness of immunologic surveillance. The distribution of human cancers points to a progressive accumulation of somatic genetic error. Sir Macfarlane Burnet has made immense contributions in the field of cancer surveillance. This paper analyses how the old masters were watching out for the hid...
