Weak convergence of random processes with immigration at random times [PDF]
Journal of Applied Probability, 2020 AbstractBy a random process with immigration at random times we mean a shot noise process with a random response function (response process) in which shots occur at arbitrary random times. Such random processes generalize random processes with immigration at the epochs of a renewal process which were introduced in Iksanov et al.

Random graphons and a weak Positivstellensatz for graphs [PDF]
Journal of Graph Theory, 2011 AbstractIn an earlier article, the authors proved that limits of convergent graph sequences can be described by various structures, including certain 2‐variable real functions called graphons, random graph models satisfying certain consistency conditions, and normalized, multiplicative and reflection positive graph parameters.

IEEE Access, 2020 Public-key encryption is often used to protect data security/privacy and secure communication in scenarios of cloud computing and edge computing. Related randomness attacks model (RRA) for public-key encryption was motivated by randomness failures.

Weak random periodic solutions of random dynamical systems
Canadian 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.

Robust amplification of Santha-Vazirani sources with three devices [PDF]
, 2015 We demonstrate that amplification of arbitrarily weak randomness is possible using quantum resources. We present a randomness amplification protocol that involves Bell experiments.

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

Purity through Factorisation [PDF]
Electronic 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.

Spin Reduction Transition in Spin-3/2 Random Heisenberg Chains [PDF]
, 2002 Random spin-3/2 antiferromagnetic Heisenberg chains are investigated using an asymptotically exact renormalization group. Randomness is found to induce a quantum phase transition between two random-singlet phases.

Differences of fracture propagation behavior for two typical fractured formations
Natural 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 ...
