Download e-book for kindle: The Panic Virus: A True Story of Medicine, Science, and Fear by Seth Mnookin

WHO comes to a decision WHICH proof ARE precise?
In 1998 Andrew Wakefield, a British gastroenterologist with a historical past of self-promotion, released a paper with a stunning allegation: the measles-mumps-rubella vaccine may possibly reason autism. The media seized carry of the tale and, within the method, helped to release the most devastating overall healthiness scares ever. within the years yet to come Wakefield will be published as a profiteer in league with class-action attorneys, and he could ultimately lose his scientific license. in the meantime one research after one other didn't locate any hyperlink among early life vaccines and autism.
Yet the parable that vaccines one way or the other reason developmental problems lives on. regardless of the inability of corroborating facts, it's been popularized by way of media personalities akin to Oprah Winfrey and Jenny McCarthy and legitimized via reporters who declare that they're simply being reasonable to “both sides” of a subject matter approximately which there's little debate. in the meantime thousands of bucks were diverted from capability breakthroughs in autism learn, households have spent their reductions on useless “miracle cures,” and declining vaccination premiums have resulted in outbreaks of lethal health problems like Hib, measles, and whooping cough. so much tragic of all is the expanding variety of childrens death from vaccine-preventable ailments.
In The Panic Virus Seth Mnookin attracts on interviews with mom and dad, public-health advocates, scientists, and anti-vaccine activists to take on a basic query: How can we make a decision what actually? The attention-grabbing solution is helping clarify every thing from the endurance of conspiracy theories approximately September 11 to the allure of talk-show hosts who call for that President Obama “prove” he was once born in the USA.
The Panic Virus is a riveting and infrequently heart-breaking clinical detective tale that explores the boundaries of rational proposal. it's the final cautionary story for our time.

Academic researchers are sure to see this as a well timed paintings. It brings jointly the paintings of major specialists in argumentation in technological know-how schooling. It provides examine combining theoretical and empirical views suitable for secondary technology school rooms. because the Nineties, argumentation experiences have elevated at a quick velocity, from stray papers to a wealth of analysis exploring ever extra refined concerns.

The most energy efficient GPU accelerated system achieved an efficiency of 958 MF/W, while the most energy efficient system using the CBE for acceleration achieved 773 MF/W (Homberg 2009). This system used an experimental interconnection network connecting nodes via the CBE internal high-speed bus. Non-accelerated systems using the latest generation IA-32 CPUs achieved an energy efficiency of about 350– 400 MF/W for HPL (Fig. 7). 3 GPU Integration and Programming Programming and code generation for both CPUs and GPUs today requires effective exploitation of parallelism for high efficiency.

Since matrix multiplication requires 2N3 operations but only 3N2 data elements need to be transferred, the data transfer time decreases in significance as N increases. The peak of the on GPU performance with CUBLAS is about 82 %, which drops to a peak of about 76 % if data transfers are included. These results are in agreement with the results reported in Phillips and Fatica (2010). Sparse Matrix-Vector Multiplication For sparse matrix-vector multiplication the results are shown in Fig. 19. 5 % of peak, a higher fraction of peak than on the CPU.
