Abstract Dislocation engineering in crystalline materials is essential when designing materials for a large range of applications.Segregation of additional elements at dislocations is frequently used to modify the influence of dislocations on material properties.Thus, the influence of the Hair dislocation elastic field on impurity segregation is of
A New Differential Frequency Hopping Scheme based on Chaotic Encryption Algorithm
Aiming at the problem that the two-dimensional uniformity of the frequency hopping pattern in differential frequency hopping communication is poor, and the frequency hopping frequency Girls Bottoms is easy to be eavesdropped, this paper designs an encryption scheme based on the pseudo-random sequence of logistic chaotic map to randomly scramble the
What Insights Do Short-Maturity (7DTE) Return Predictive Regressions Offer about Risk Preferences in the Oil Market?
In this study, we investigate the ability of three higher-order risk-neutral return cumulants to predict short maturity (weekly) returns of oil futures.Our data includes weekly West Texas Crude Oil futures options that expire in 7 days (7DTE).Using a model-free approach, we estimate these risk-neutral return cumulants at the beginning Hay Net Fille
Seagrass and Oyster Reef Restoration in Living Shorelines: Effects of Habitat Configuration on Invertebrate Community Assembly
Restoration projects provide a valuable opportunity to experimentally establish foundational habitats in different combinations to test relative effects on community assembly.We evaluated the development of macroinvertebrate communities in response to planting of eelgrass (Zostera marina) and construction of reefs intended to support the Olympia oy
