Building Molecules by a Self‐Replicator That Catalyzes Acyl Hydrazone Formation
Angewandte Chemie, EarlyView.A self‐replicator efficiently catalyzes the formation of acyl hydrazone bonds between a set of different substrates. In addition to previously reported (bond‐breaking) catalytic activity, this renders the self‐replicator highly promiscuous, which is a good starting point for Darwinian experiments en route to de‐novo life.

A Lévy-Driven Stochastic Queueing System with Server Breakdowns and Vacations
Mathematics, 2020 Motivated by modelling the data transmission in computer communication networks, we study a Lévy-driven stochastic fluid queueing system where the server may subject to breakdowns and repairs.

Testing the Marketing Performance of German Wheat Farmers
Agribusiness, EarlyView.ABSTRACT This paper analyses the marketing performance of wheat farmers in Germany. Wheat sales data from 465 individual farms over a 12‐year period are used to test against different market benchmarks. Market benchmarks are constructed by simulating passive trading agents using regional wheat prices.

Towards More Robust Nanobioscience: Launching the NanoBubbles Replication Initiative
Angewandte Chemie, EarlyView.The NanoBubbles Reproducibility Initiative investigates the robustness of highly cited articles in nanobioscience. Here, we document the process of setting up the initiative from corpus creation to publishing results. We also present platforms that we adopted and challenges that we faced.

Lévy-driven polling systems and continuous-state branching processes
Stochastic Systems, 2011 In this paper we consider a ring of N ≥ 1 queues served by a single server in a cyclic order. After having served a queue (according to a service discipline that may vary from queue to queue), there is a switch-over period and then the server serves the ...

A recursive pricing method for autocallables under multivariate subordination
Quantitative Finance and Economics, 2019 In this paper we develop a new class of models for pricing autocallables based on multivariate subordinate Orstein Uhlenbeck (OU) processes. Starting from d independent OU processes and an independent d-dimensional Lévy subordinator, we construct a new ...

Review of Memristors for In‐Memory Computing and Spiking Neural Networks
Advanced Intelligent Systems, EarlyView.Memristors uniquely enable energy‐efficient, brain‐inspired computing by acting as both memory and synaptic elements. This review highlights their physical mechanisms, integration in crossbar arrays, and role in spiking neural networks. Key challenges, including variability, relaxation, and stochastic switching, are discussed, alongside emerging ...

Mixed Periodic-Classical Barrier Strategies for Lévy Risk Processes
Risks, 2018 Given a spectrally-negative Lévy process and independent Poisson observation times, we consider a periodic barrier strategy that pushes the process down to a certain level whenever the observed value is above it.

Analysis of a Stochastic SICR Epidemic Model Associated with the Lévy Jump
Applied Sciences, 2022 We propose and study a Susceptible-Infected-Confined-Recovered (SICR) epidemic model. For the proposed model, the driving forces include (for example) the Brownian motion processes and the jump Lévy noise.

Stochastic monotonicity and duality for one-dimensional Markov processes [PDF]
, 2011 The theory of monotonicity and duality is developed for general one-dimensional Feller processes, extending the approach from [11]. Moreover it is shown that local monotonicity conditions (conditions on the Lévy kernel) are sufficient to prove the well-
