Isogeny volcanoes
The remarkable structure and computationally explicit form of isogeny graphs of elliptic curves over a finite field has made them an important tool for computational number theorists and practitioners of elliptic curve cryptography. This expository paper recounts the theory behind these graphs and examines several recently developed algorithms that realize substantial (often dramatic) performan...

aerosol Any suspended particle in the atmosphere. An aerosol can be a liquid droplet, such as sulfuric acid, or a solid, such as ash or tephra. Arctic Oscillation A strengthening or weakening of the polar vortex in the Northern Hemisphere, the main pattern of oscillation of winter variation of extratropical atmospheric circulation.

متن کاملImpossible Frontiers
A key result of the Capital Asset Pricing Model (CAPM) is that the market portfolio— the portfolio of all assets in which each asset’s weight is proportional to its total market capitalization—lies on the mean-variance-efficient frontier, the set of portfolios having mean-variance characteristics that cannot be improved upon. Therefore, the CAPM cannot be consistent with efficient frontiers for...
متن کاملImpossible Words?
The idea that quotidian, middle-level concepts typically have internal structure-definitional, statistical, or whatever—plays a central role in practically every current approach to cognition. Correspondingly, the idea that words that express quotidian, middle-level concepts have complex representations "at the semantic level" is recurrent in linguistics; it is the defining thesis of what is of...
متن کاملImpossible fractals
Impossible objects are a type of optical illusion involving ambiguous visual descriptions of figures that cannot physically exist. It is shown by way of example that such objects can be further developed using standard fractal techniques to create new, more complex designs that retain the perceptual illusion, sometimes allowing additional illusions to emerge from the process. The balanced Pytha...
