Out-of-time-order correlators (OTOCs) have proven to be a useful tool for studying thermalization in quantum systems. In particular, the exponential growth of OTOCS, or scrambling, is sometimes taken as an indicator chaos systems, despite fact that saddle points integrable systems can also drive rapid OTOCs. By analyzing Dicke model and driven Bose-Hubbard dimer, we demonstrate OTOC by can, non...

The way in which the triple bond in CO dissociates, a key reaction step in the Fischer-Tropsch (FT) reaction, is a subject of intense debate. Direct CO dissociation on a Co catalyst was probed by 12C16O/13C18O scrambling in the absence and presence of H2. The initial scrambling rate without H2 was significantly higher than the rate of CO consumption under CO hydrogenation conditions, which indi...

Various noncanonical sentence constructions are derived from basic sentence structures by a phrase displacement called Movement. The moved phrase (filler) leaves a silent copy at the extracted position (gap) and is reactivated when the hearer/reader passes over the gap. Consequently, memory operations are assumed to occur to establish the filler-gap link. For languages that have a relatively fr...

Distributed databases operating over wide-area networks such as the Internet, must deal with the unpredictable nature of the performance of communication. The response times of accessing remote sources can vary widely due to network congestion, link failure, and other problems. In such an unpredictable environment, the traditional iterator-based query execution model performs poorly. We have de...

The TMEM16 protein family has 10 members, each of which carries 10 transmembrane segments. TMEM16A and 16B are Ca2+-activated Cl- channels. Several other members, including TMEM16F, promote phospholipid scrambling between the inner and outer leaflets of a cell membrane in response to intracellular Ca2+ However, the mechanism by which TMEM16 proteins translocate phospholipids in plasma membranes...

A scheme of speech scrambling based on imitation of a super Gaussian signal has recently been proposed. This scheme gives scrambled signals with zero trace of the original content and high scrambling degree. In this paper, the scheme is used in two scenarios: scrambling with private key method (symmetric cryptography), and scrambling with one private and one public key method (a hybrid between ...
