Miners' Reward Elasticity and Stability of Competing Proof‐of‐Work Cryptocurrencies
International Economic Review, EarlyView.ABSTRACT Proof‐of‐Work cryptocurrencies employ miners to sustain the system through algorithmic reward adjustments. We develop a stochastic model of the multicurrency mining and identify conditions for stable transaction speeds. Bitcoin's algorithm requires hash supply elasticity <$<$1 for stability, while ASERT remains stable for any elasticity and ...

On the security of the Courtois-Finiasz-Sendrier signature
Open Mathematics, 2018 We prove that a variant of the Courtois-Finiasz-Sendrier signature is strongly existentially unforgeable under chosen message attack in the random oracle model, assuming hardness of the Permuted Goppa Syndrome Decoding Problem (also known as the ...

Practical Lattice-Based Multisignature Schemes for Blockchains
IEEE Access, 2019 Compact multisignature is vital for shrinking the signature size of decentralized blockchain. All practical compact multisignature schemes have been constructed from the discrete logarithm problem which is potentially vulnerable to quantum computing ...

Medical Knowledge Integration Into Reinforcement Learning Algorithms for Dynamic Treatment Regimes
International Statistical Review, EarlyView.Summary The goal of precision medicine is to provide individualised treatment at each stage of chronic diseases, a concept formalised by dynamic treatment regimes (DTR). These regimes adapt treatment strategies based on decision rules learned from clinical data to enhance therapeutic effectiveness.

International Statistical Review, EarlyView.Summary In high‐dimensional survival analysis, effective variable selection is crucial both for model interpretation and predictive performance. This paper investigates Cox regression with lasso and adaptive lasso penalties in genomic datasets where covariates far outnumber observations.

The Cross and Conflict: How Do Christians Impact Protest Dynamics?
Journal for the Scientific Study of Religion, EarlyView.ABSTRACT This study examines the relationship between Christian actors, practices, and sacred sites in US protests and demonstrations, focusing on how political ideology shapes conflict outcomes. Using event‐level data from the Armed Conflict Location & Event Data Project (ACLED), the analysis explores 63,000 protest events from 2020 to 2024 ...

Journal for the Scientific Study of Religion, EarlyView.ABSTRACT Drawing on 3 years of qualitative fieldwork at a United Methodist church and a Catholic parish in Minneapolis‐St. Paul, I analyze how White, liberal congregations translated race‐conscious ideals into organizational practice in the wake of the 2020 police murder of George Floyd.

Adapting the Weaknesses of the Random Oracle Model to the Generic Group Model [PDF]
, 2002 The generic group model has recently been used to prove the security of certain asymmetric encryption and signature schemes. This paper presents results that show that there exist problems in that are provably hard in the generic group model but easy to solve whenever the random encoding function is replaced with a specific encoding function (or one ...

Journal of Time Series Analysis, EarlyView.ABSTRACT The paper deals with the construction of a synthetic indicator of economic growth, obtained by projecting a quarterly measure of aggregate economic activity, namely gross domestic product (GDP), into the space spanned by a finite number of smooth principal components, representative of the medium‐to‐long‐run component of economic growth of a ...
