Octonion Internal Space Algebra for the Standard Model

open access: yesUniverse, 2023
This paper surveys recent progress in our search for an appropriate internal space algebra for the standard model (SM) of particle physics. After a brief review of the existing approaches, we start with the Clifford algebras involving operators of left ...

Crystal Structure of a Eukaryotic GEN1 Resolving Enzyme Bound to DNA

open access: yesCell Reports, 2015
We present the crystal structure of the junction-resolving enzyme GEN1 bound to DNA at 2.5 Å resolution. The structure of the GEN1 protein reveals it to have an elaborated FEN-XPG family fold that is modified for its role in four-way junction resolution.

On the structural complexity of a protein [PDF]

open access: yesProtein Engineering, Design and Selection, 2003
The determination of the configuration of a protein in three-dimensional (3D) space constitutes one of the major challenges in molecular biology research today. A method consists in choosing a protein structure from a database that minimizes an energy function.

The Complexity of Countable Structures [PDF]

open access: yesThe Bulletin of Symbolic Logic, 2018
Author(s): Harrison-Trainor, Matthew Alexander | Advisor(s): Montalban, Antonio | Abstract: We prove various results about the complexity of countable structures, both computable and arbitrary.We begin by investigating descriptions of countable structures in the infinitary logic Lω1ω.

Cryptographic Puzzles and Complex Systems

open access: yes, 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.

Do evolutionary algorithm dynamics create complex network structures? [PDF]

open access: yes, 2021
This paper presents a novel method for visualizing the dynamics of evolutionary algorithms in the form of complex networks. We discuss the analogy between individuals in populations in an arbitrary evolutionary algorithm and vertices of a complex network,
