Hydrated Excess Protons Can Create Their Own Water Wires
Grotthuss shuttling of an excess proton charge defect through hydrogen bonded water networks has long been the focus of theoretical and experimental studies. In this work we show that there is a related process in which water molecules move ("shuttle") through a hydrated excess proton charge defect in order to wet the path ahead for subsequent proton charge migration. This process is illustrate...
متن کاملWhen Cryptocurrencies Mine Their Own Business
Bitcoin and hundreds of other cryptocurrencies employ a consensus protocol called Nakamoto consensus which reward miners for maintaining a public blockchain. In this paper, we study the security of this protocol with respect to rational miners and show how a minority of the computation power can incentivize the rest of the network to accept a blockchain of the minority’s choice. By deviating fr...
متن کاملTo Create Psychology’s Own Capital
“We do not want to deny our past. We do not suffer from megalomania by thinking that history begins with us. We do not want a brand-new and trivial name from history. We want a name covered by the dust of centuries. We regard this as our historical right, as an indication of our historical role, our claim to realize psychology as a science. We must view ourselves in connection with and in relat...
متن کاملChildren Learn Better When They Select Their Own Data
Human learners ask questions, manipulate objects, and perform interventions on their environment. These behaviors are true of adults, but even more so for young children. Recent studies have demonstrated that adults learn better under conditions of selection learning, where they can make decisions about the information they wish to acquire, as compared to reception learning, where they merely o...
متن کاملNeurons Tune Their Own Excitability When They Make A Decision
The brain is usually considered to be an extraordinarily complex object while a neuron is believed an ideal logical element. This idealization does not correspond to the real neural system properties. Experimental data give trustworthy evidence that a neuron is a microcosm of the brain. The firing threshold seems to be a dynamic property of an excitable membrane. Neurons appear to evaluate the ...
