Hopping Conductivity in Single Crystals (Cd0.6Zn0.32Mn0.08)3As2 (RESEARCH NOTE)
The growth processes of Tetragonal single crystals of solid solution (Cd0.6Zn0.32Mn0.08)3As2, space group P42/nmc, has been synthesized by Bridgman method. Conductivity and magnetoresistance of (Cd0.6Zn0.32Mn0.08)3As2 were measured in the range 1.6K to 300K and in magnetic field up to 25 T. Crossover from Mott variable-range-hopping conductivity mechanism close to helium temperatures. In this w...
متن کاملEfficiently Scrapping Boilerplate Code in OCaml
We present an adaptation of a well-known generic programming technique, often referred to as “Scrap Your Boilerplate”, or SYB, to Objective Caml language. Since the original implementation for Haskell essentially relies on the presence of type classes, the first task in the course of adaptation is to express the main primitives of this approach in a way natural for Objective Caml. Besides that ...
متن کاملOptimal Scrapping and Technology Adoption under Uncertainty
A firm has to decide sequentially to replace its technology and to implement a new one chosen among an increasing range over time under technological and market uncertainty. The optimal decision rule is a (s, S) style policy where the trigger and target technology levels are positively correlated with boom persistence and negatively related with recession persistence and technological uncertain...
متن کاملBiologists Home in on Turing Patterns
In 1952, Alan Turing, a British mathematician best known for his work on code-breaking and artificial intelligence, was convicted of engaging in homosexual acts and sentenced to chemical castration. Amid that personal drama, he still found the time to publish a visionary paper on the mathematics of regularly repeating patterns in nature, which could be applied to the stripes on tigers and zebra...
