Cryptographic Puzzles and Complex Systems

, 2021
A puzzle lies behind password authentication (PA) and blockchain proof of work (PoW). A cryptographic hash function is commonly used to implement them. The potential problem with secure hash functions is their complexity and rigidity.

Complex Potentials

Journal of Mathematical Analysis and Applications, 1999
The authors show that complex potentials associated with locally sourceless and locally irrotational flows defined on (possibly infinitely connected) domains in the complex plane have logarithmic singularities. Additionally, some applications to flows around contours are given.

Quantum complex Hénon–Heiles potentials [PDF]

Physics Letters A, 2001
Quantum-mechanical PT-symmetric theories associated with complex cubic potentials such as V=x^2+y^2+igxy^2 and V=x^2+y^2+z^2+igxyz, where g is a real parameter, are investigated. These theories appear to possess real, positive spectra. Low-lying energy levels are calculated to very high order in perturbation theory.

Neuropathophysiological potential of Guillain-Barré syndrome anti-ganglioside-complex antibodies at mouse motor nerve terminals [PDF]

, 2011
Objectives:  Anti-ganglioside antibodies are present in approximately half of Guillain–Barré syndrome (GBS) patients. Recently, it has been shown that a considerable proportion of these patients has serum antibodies against antigenic epitopes formed by a

Flow in Fractured Porous Media Modeled in Closed-Form: Augmentation of Prior Solution and Side-Stepping Inconvenient Branch Cut Locations

Fluids, 2020
Carefully chosen complex variable formulations can solve flow in fractured porous media. Such a calculus approach is attractive, because the gridless method allows for fast, high-resolution model results.

ORGANISMAL COMPLEXITY AND THE POTENTIAL FOR EVOLUTIONARY DIVERSIFICATION [PDF]

Evolution, 2014
We present two theoretical approaches to investigate whether organismal complexity, defined as the number of quantitative traits determining fitness, and the potential for adaptive diversification are correlated. The first approach is independent of any specific ecological model and based on curvature properties of the fitness landscape as a function ...

The respiratory arsenite oxidase: structure and the role of residues surrounding the Rieske cluster [PDF]

, 2013
The arsenite oxidase (Aio) from the facultative autotrophic Alphaproteobacterium Rhizobium sp. NT-26 is a bioenergetic enzyme involved in the oxidation of arsenite to arsenate.
