Beginning in 1992, the Slow The Spread (STS) pilot project was initiated to target gypsy moth (Lymantria dispar L.) spread rate reduction by controlling populations in the transition zone. The project uses intensive monitoring techniques, with pheromone-baited sticky moth traps, to detect low-level populations and target them for eradication. The primary objective of the pilot project was to ev...

A trapper of eighteenth century needed a box of matches, a gun and a knife, and perhaps, a tent and a canoe or a dogsled to survive in the wilderness. Today, almost anyone of us would feel uncomfortable without, in addition, GPS, a mobile phone with internet access, a medicine-chest with at least aspirin, an antibiotic as well as a serum against snake bite, and a lot more to master the same sit...

We introduce Casper, a proof of stake-based finality system which overlays an existing proof of work blockchain. Casper is a partial consensus mechanism combining proof of stake algorithm research and Byzantine fault tolerant consensus theory. We introduce our system, prove some desirable features, and show defenses against long range revisions and catastrophic crashes. The Casper overlay provi...

Abstract We present a GPU-accelerated cosmological simulation code, PhotoNs-GPU, based on an algorithm of Particle Mesh Fast Multipole Method (PM-FMM), and focus the GPU utilization optimization. A proper interpolated method for truncated gravity is introduced to speed up special functions in kernels. verify code mixed precision different levels theinterpolated GPU. run with single roughly two ...

We generalize the deterministic simulation theorem of Raz and McKenzie [RM99], to any gadget which satisfies certain hitting property. We prove that inner-product and gap-Hamming satisfy this property, and as a corollary we obtain deterministic simulation theorem for these gadgets, where the gadget’s inputsize is logarithmic in the input-size of the outer function. This answers an open question...

The shuttle effect of soluble lithium polysulfides (LPS), which causes rapid capacity fading, remains a lingering issue for lithium-sulfur batteries (LSBs). Herein, we report new type reactive molecule-based LPS trapper, zinc acetate-diethanolamine (Zn(OAc)2·DEA), demonstrates molecular efficiency 1.8 trapping, approaching its theoretical limit 2, is the highest trapping capability reported so ...

Documentary heritage reflects the diversity of languages, peoples and cultures. It is the mirror of the world and its memory. But this memory is fragile. Every day, irreplaceable parts of this memory disappear for ever. A considerable proportion of the world's documentary heritage disappears through ‘natural’ causes: acidified paper crumbles away, leather, parchment, film and magnetic tape are ...

Social networks have emerged as a new paradigm for everyday communication, as well as for promoting collaboration within enterprises and organizations. Using current technology, social network participants not only exchange information but also invoke external applications in the form of gadgets. In order to provide enhanced, complex functionality to participants, enabling them to complete a sp...

It was stated in Lecture 4 that under an adversarial queueing model, FIFO can be made unstable at arbitrarily low rates, r. The class began with a presentation demonstrating this by an example. Earlier work [2], [5], [4], [6] had shown that FIFO is unstable at rates exceeding .85, .83, .749 and .5 respectively, under an adversarial queueing model. In [7] the authors show that an adversarial inj...
