Computing discrete logarithms in an interval [PDF]
Mathematics of Computation, 2012 The discrete logarithm problem in an interval of size N in a group G is: Given g, h ∈ G and an integer N to find an integer 0 ≤ n ≤ N , if it exists, such that h = gn. Previously the best low-storage algorithm to solve this problem was the van Oorschot and Wiener version of the Pollard kangaroo method.

Cryptanalysing the critical group: efficiently solving Biggs's discrete logarithm problem
Journal of Mathematical Cryptology, 2009 Biggs has recently proposed the critical group of a certain class of finite graphs as a platform group for cryptosystems relying on the difficulty of the discrete log problem. The paper uses techniques from the theory of Picard groups on finite graphs to

Advanced Materials, EarlyView.This work reveals that charge transport in nickel benzenehexathiol coordination nanosheets is governed by variable‐range hopping reflecting structural disorder. Electrolyte gating induces a switch in dominant carrier polarity from p‐type to n‐type and leads to an improvement in thermoelectric performance.
