Gaining sleep while losing synapses

Losing Weight by Gaining Edges

We present a new way to encode weighted sums into unweighted pairwise constraints, obtaining the following results. – Define the k-SUM problem to be: given n integers in [−n, n] are there k which sum to zero? (It is well known that the same problem over arbitrary integers is equivalent to the above definition, by linear-time randomized reductions.) We prove that this definition of k-SUM remains...

Gaining and losing the thermophilic adaptation in prokaryotes.

We studied the evolution of thermophily in prokaryotes using the phylogenetic relationships between 279 bacteria and archaea and their thermophilic amino acid composition signature. Our findings suggest several examples in which the capacity of thermophilic adaptation has been gained or lost over relatively short evolutionary periods throughout the evolution of prokaryotes.

Pinching Pennies While Losing Dollars Efficiency Tradeoffs in Ada

All real-time embedded software projects eventually hit the wall when they trade elegance for efficiency. The major recipient of the blame is often ’that darn tasking’ or ’those silly OO concepts’. The actual culprit, unknowingly, is the front line software engineer. This paper is a group of test cases that can be applied to compiler to give direction to the developers as to the performance of ...

Grow rich while you sleep

We use data from a promotion campaign of NH-Hoteles to study self-selection of participants in a gift-exchange experiment. The promotion campaign allowed guests to pay any non negative amount of money for a stay in one of 36 hotels in Belgium and the Netherlands. The data allow us to distinguish between ‘regular guests’, who booked prior to the announcement of the promotion campaign and guests ...
