SCIENCE sciencemag.org significance that each can reduce cases and deaths. But efficacy in a carefully managed, tightly monitored study does not equal effectiveness in the messiness of the real world. Confusing matters further still, weather patterns, an economic upswing, or improved housing can also have a big impact on disease. The CGD researchers are part of a growing movement that seeks har...

Thrombocytopenia is a well- recognized complication of heparin therapy. The diagnosis is mostly clinical and the main value of laboratory testing is in excluding the diagnosis. We describe here a patient with stroke who had aspiration pneumonia leading to sepsis. She developed atrial fibrillation and received heparin which had to be stopped prematurely due to melena. Within 5 days of heparin, s...

techniques attempt to differentiate between stego-objects and cover-objects. In recent work we developed an analytic upper bound for the steganographic capacity of LSB based steganographic techniques for a given false of detection. In this paper we look at adaptive steganographic techniques. Adaptive steganographic techniques steps to escape detection. We explore different techniques that can b...

Have you a scientific hero? Ken Machin, not just because he saved my PhD but mainly because of his contributions to biology. After graduating in physics, he did a PhD in radio-astronomy. Then, remarkably, he was appointed to a post in the Cambridge University Zoology Department, helping zoologist colleagues with the physical implications of their research. He and John Pringle showed how occasio...
متن کاملHats, auctions and derandomization
We investigate derandomizations of digital good randomized auctions. We propose a general derandomization method which can be used to show that for every random auction there exists a deterministic auction having asymptotically the same revenue. In addition, we construct an explicit optimal deterministic auction for bi-valued auctions.
