Fast Factoring of Integers

open access: yes, 2005
An algorithm is given to factor an integer with $N$ digits in $\ln^m N$ steps, with $m$ approximately 4 or 5. Textbook quadratic sieve methods are exponentially slower. An improvement with the aid of an a particular function would provide a further exponential speedup.

The effects of agricultural machinery services and land fragmentation on farmers' straw returning behavior

open access: yesAgribusiness, EarlyView.
Abstract Straw returning is important for rural ecological management and sustainable agricultural development. Using farm survey data for Anhui Province, China, in 2020, we applied the double‐hurdle model to investigate the impact of agricultural machinery services and land fragmentation on farmers' straw‐returning behavior, and to explore the ...
