The computational complexity of PEPS [PDF]

open access: yes, 2006
We determine the computational power of preparing Projected Entangled Pair States (PEPS), as well as the complexity of classically simulating them, and generally the complexity of contracting tensor networks.

Robustly Self-Ordered Graphs: Constructions and Applications to Property Testing [PDF]

open access: yesTheoretiCS, 2022
A graph $G$ is called self-ordered (a.k.a asymmetric) if the identity permutation is its only automorphism. Equivalently, there is a unique isomorphism from $G$ to any graph that is isomorphic to $G$. We say that $G=(V,E)$ is robustly self-ordered if the

The Computational Complexity of Linear Optics [PDF]

open access: yes, 2010
We give new evidence that quantum computers -- moreover, rudimentary quantum computers built entirely out of linear-optical elements -- cannot be efficiently simulated by classical computers.

Computational Complexity

open access: yesEntropy, 2017
Complex systems (CS) involve many elements that interact at different scales in time and space. The challenges in modeling CS led to the development of novel computational tools with applications in a wide range of scientific areas.

Supplemented Alkaline Phosphatase Supports the Immune Response in Patients Undergoing Cardiac Surgery: Clinical and Computational Evidence

open access: yesFrontiers in Immunology, 2018
Alkaline phosphatase (AP) is an enzyme that exhibits anti-inflammatory effects by dephosphorylating inflammation triggering moieties (ITMs) like bacterial lipopolysaccharides and extracellular nucleotides. AP administration aims to prevent and treat peri-

Computational Oncology in the Multi-Omics Era: State of the Art

open access: yesFrontiers in Oncology, 2020
Cancer is the quintessential complex disease. As technologies evolve faster each day, we are able to quantify the different layers of biological elements that contribute to the emergence and development of malignancies.

Computational Complexity in Additive Hedonic Games [PDF]

open access: yes, 2008
We investigate the computational complexity of several decision problems in hedonic coalition formation games and demonstrate that attaining stability in such games remains NP-hard even when they are additive.

Performance of Some Estimators of Relative Variability

open access: yesFrontiers in Applied Mathematics and Statistics, 2019
The classic coefficient of variation (CV) is the ratio of the standard deviation to the mean and can be used to compare normally distributed data with respect to their variability, this measure has been widely used in many fields. In the Social Sciences,

Computational Complexity and Phase Transitions

open access: yes, 2000
Phase transitions in combinatorial problems have recently been shown to be useful in locating "hard" instances of combinatorial problems. The connection between computational complexity and the existence of phase transitions has been addressed in ...
