Hypergraphs, Quasi-randomness, and Conditions for Regularity

open access: yesJournal of Combinatorial Theory - Series A, 2002
The study of quasi-randomness is a flourishing topic on uniform hypergraphs. F. R. K. Chung and R. L. Graham (among others) investigated thoroughly quasi-random uniform hypergraphs of density 1/2, showing a series of important equivalent statements about these structures. In this investigations the notion of deviation plays a central role.

Breaking Through the Bottleneck of Wireless Physical-Layer Key Generation by Dynamic Agile Reconfigurable Intelligent Surface Antenna (DARISA) [PDF]

open access: yesEntropy
In widely deployed Internet of Things (IoT) scenarios, physical-layer key generation (PLKG) serves as a useful complement to conventional cryptographic methods, yet it often suffers from a fundamentally low key generation rate, which becomes particularly

Hopf-Hopf bifurcation analysis and chaotic delayed-DNA audio encryption using cubic nonlinear optoelectronic oscillator [PDF]

open access: yesScientific Reports
The study presents a hybrid model for encryption which is based on the utilization of nonlinear chaotic behaviors in a cubic optoelectronic oscillator (OEO) as well as biomimetic DNA computation to achieve secure and lossless protection of audio data ...

Practical randomness amplification and privatisation with implementations on quantum computers [PDF]

open access: yesQuantum, 2023
We present an end-to-end and practical randomness amplification and privatisation protocol based on Bell tests. This allows the building of device-independent random number generators which output (near-)perfectly unbiased and private numbers, even if ...

Quasi‐random hypergraphs [PDF]

open access: yesRandom Structures & Algorithms, 1989
AbstractWe introduce an equivalence class of varied properties for hypergraphs. Any hypergraph possessing any one of these properties must of necessity possess them all. Since almost all random hypergraphs share these properties, we term these properties quasi‐random.

Multi-scale analysis of effect of uncertainties on mechanical properties of particle reinforced metal matrix composites and experimental validation

open access: yesCailiao gongcheng, 2023
The results of quasi-static tensile experiments on the 20%(volume fraction) SiCp/2009Al composite show a significant dispersion of the mechanical properties such as failure strain.

Abrahamic reflections on randomness and providence [PDF]

open access: yes, 2022
This open access book addresses the question of how God can providentially govern apparently ungovernable randomness. Medieval theologians confidently held that God is provident, that is, God is the ultimate cause of or is responsible for everything that

Quasi-random graphs [PDF]

open access: yesCombinatorica, 1988
We introduce a large equivalence class of graph properties, all of which are shared by so-called random graphs. Unlike random graphs, however, it is often relatively easy to verify that a particular family of graphs possesses some property in this class.

The Evolutionary Process in Lamarckism and Darwinism: similarities and differences [PDF]

open access: yesJournal of Philosophical Investigations, 2022
It is a widely held view that the inheritance of acquired characteristics plays an important role in Lamarck's ideas about evolution, and there are some counter-instances against it. As a result, his theory is called into question.
