We show that modified versions of the linear congruential generator and the shift register generator are provably good for amplifying the correctness of a probabilistic algorithm. More precisely, if r random bits are needed for a BPP algorithm to be correct with probability at least 2/3, then O(r + k) bits are needed to improve this probability to 1 − 2−k. We also present a different pseudo-ran...

Our understanding of how genetic changes underlie the evolution of traits is growing fast. Two new studies now show that changes in the same genetic loci can drive the evolution of the same trait in multiple Drosophila species.

In recent years Indonesia is struggling with their waste. Every day, generates around 175,000 tons of Some waste takes a lot time to decompose normally and even though many people know this fact, there are still throwing without giving second thought. This problem has not been solved yet it’s because in don’t how recycle properly. order solve problem, platform needed provide information on wast...

The nuclear fuel cycle can be truly closed by supp lementing today’s thermal reactors with fast reactors, which can use as fuel the heavy, fissionable isotopes that accumulate in thermal-reactor fuel. In a fully closed cycle, the waste for disposal consists only of fission products with trace amounts of actinides. Eliminating the transuranics reduces the heat load in the repository, increasing ...

This comprehensive work explores the research performed inoptimization of the collection bin and in recycle bin location-allocation issues in solidwaste management. Although the collection phase of solid waste management accountsfor a significant proportion of the municipal budget, it has attracted only limitedattention of the researchers. Optimization of the collection bin and recycle bin loca...

Using the price for recycling used home appliances as a variable in the decision-making process, this paper studies the pricing decision-making process of the home appliances enterprises when a wholesale and retail price for the green home appliances have already been determined by other methods. In consideration of the influences of the effective recycle behavior of the used home appliances to...
