Weak random periodic solutions of random dynamical systems

open access: yesCanadian Mathematical Bulletin, 2023
AbstractWe first introduce the concept of weak random periodic solutions of random dynamical systems. Then, we discuss the existence of such periodic solutions. Further, we introduce the definition of weak random periodic measures and study their relationship with weak random periodic solutions.

Correlation defense for quantum randomness

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2020
New nonparametric methods were developed for verification and monitoring of quantum randomness based on the ranged correlation function (RCF) and a sequence of the ranged amplitudes (SRA).

Purity through Factorisation [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2018
We give a construction that identifies the collection of pure processes (i.e. those which are deterministic, or without randomness) within a theory containing both pure and mixed processes.

Weak Verifiable Random Functions [PDF]

open access: yes, 2009
Verifiable random functions (VRFs), introduced by Micali, Rabin and Vadhan, are pseudorandom functions in which the owner of the seed produces a public-key that constitutes a commitment to all values of the function and can then produce, for any input x , a proof that the function has been evaluated correctly on x , preserving pseudorandomness for all ...

HIGHER RANDOMNESS AND GENERICITY

open access: yesForum of Mathematics, Sigma, 2017
We use concepts of continuous higher randomness, developed in Bienvenu et al. [‘Continuous higher randomness’, J. Math. Log. 17(1) (2017).], to investigate $\unicode[STIX]{x1D6F1}_{1}^{1}$

Threshold Models of Collective Behavior II: The Predictability Paradox and Spontaneous Instigation

open access: yesSociological Science, 2020
Collective behavior can be notoriously hard to predict. We revisited a possible explanation suggested by Granovetter’s classic threshold model: collective behavior can unexpectedly fail, despite a group’s strong interest in the outcome, because of the ...

Impact of Traffic Load Randomness on Fatigue of Steel Bridges

open access: yesThe Baltic Journal of Road and Bridge Engineering, 2020
The article considers the influence of the randomness of traffic load on the fatigue of elements of steel bridge structures. The phenomenon occurs specifically in the case of bridges characterized by significant width, with many traffic lanes and a high ...

Differences of fracture propagation behavior for two typical fractured formations

open access: yesNatural Gas Industry B, 2022
Hydraulic fracturing is an important stimulation measure for the development of coalbed methane and shale gas. At present, the fracture initiation and propagation mechanism in coal and shale formations are still unclear, which brings difficulties to ...

A normative theory of luck

open access: yesFrontiers in Psychology, 2023
Psychologists have identified heuristics and biases that can cause people to make assumptions about factors that contribute to the success of individuals and firms, whose outcomes may have actually resulted primarily from randomness.
