Ring transformation of condensed pyrimidines by enamines and ynamines. Formation of condensed pyridines and condensed diazocines.

Condensed and Desiccated Milk,

Milk is a bulky product, expensive to transport, and very susceptible to contamination, which in a short time renders it unpalatable. In its natural state it contains al^out 87 per cent of water, which is a comparatively worthless constituent. ' Efforts to reduce the water content of milk, leaving the solids in ; a more concentrated form without destroying their food value, and at the same time...

Condensed matter

Foreword Physics and physicists play a vital role in underpinning our way of life, improving its quality and contributing in a major way to wealth creation. Innovations as powerful and diverse as the World Wide Web and magnetic resonance imaging (MRI) have emerged from studies in basic physics, becoming everyday technologies in just two decades. It is, therefore, a worthwhile challenge to specu...

Condensed Unpredictability

We consider the task of deriving a key with high HILL entropy (i.e., being computationally indistinguishable from a key with high min-entropy) from an unpredictable source. Previous to this work, the only known way to transform unpredictability into a key that was indistinguishable from having min-entropy was via pseudorandomness, for example by Goldreich-Levin (GL) hardcore bits. This approach...

Of Matters Condensed

The American Physical Society (APS) March Meeting of condensed matter physics has grown to nearly 10,000 participants, comprises 23 individual APS groups, and even warrants its own hashtag (#apsmarch). Here we analyze the text and data from March Meeting abstracts of the past nine years and discuss trends in condensed matter physics over this time period. We find that in comparison to atomic, m...
