Stop Using Limiting Stimuli as a Measure of Sensitivities of Energetic Materials
Propellants, Explosives, Pyrotechnics, Volume 51, Issue 8, Page 1386-1400, August 2026.ABSTRACT Accurately estimating the sensitivity of explosive materials is a potentially life‐saving task that requires standardised protocols across nations. One of the most widely applied procedures worldwide is the so‐called ‘1‐In‐6’ test from the United Nations (UN) Manual of Tests in Criteria, which estimates a ‘limiting stimulus’ for a material. In

Random Structures &Algorithms, Volume 69, Issue 1, August 2026.ABSTRACT We study a random recursive tree model featuring complete redirection called the random friend tree and introduced by Saramäki and Kaski (2004). Vertices are attached sequentially, one by one, by selecting an existing target vertex and connecting to one of its neighbours (or friends), chosen uniformly at random.

Miners' Reward Elasticity and Stability of Competing Proof‐of‐Work Cryptocurrencies
International Economic Review, Volume 67, Issue 3, Page 957-976, August 2026.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 Metric Choice in Dimension Reduction for Fréchet Regression
International Statistical Review, Volume 94, Issue 2, Page 325-346, August 2026.Summary Fréchet regression is becoming a mainstay in modern data analysis for analysing non‐traditional data types belonging to general metric spaces. This novel regression method is especially useful in the analysis of complex health data such as continuous monitoring and imaging data.

A Comparative Review of Specification Tests for Diffusion Models
International Statistical Review, Volume 94, Issue 2, Page 347-381, August 2026.Summary Diffusion models play an essential role in modelling continuous‐time stochastic processes in the financial field. Therefore, several proposals have been developed in the last decades to test the specification of stochastic differential equations.

Inference on the Attractor Space via Functional Approximation
Oxford Bulletin of Economics and Statistics, Volume 88, Issue 4, Page 643-657, August 2026.ABSTRACT This paper discusses semiparametric inference on hypotheses on the cointegration and the attractor spaces for I(1) linear processes with moderately large cross‐sectional dimension. The approach is based on sample canonical correlations and functional approximation of Brownian motions, and it can be applied both to the whole system and or to ...

Least Trimmed Squares: Cointegration and Outliers
Oxford Bulletin of Economics and Statistics, Volume 88, Issue 4, Page 690-711, August 2026.ABSTRACT When applying the cointegrated autoregressive distributed lag model it is common to include indicator variables for outliers. This is often done in a somewhat ad hoc way. Least Trimmed Squares estimation provides a more systematic approach. This estimator is robust to a large number of outliers of many types.

A short proof of a central limit theorem for the order of the giant component and k$k$‐core
Bulletin of the London Mathematical Society, Volume 58, Issue 8, August 2026.Abstract In this note we outline a new and simple approach to proving central limit theorems for various ‘global’ graph parameters that have robust ‘local’ approximations, using the Efron–Stein inequality, which relies on a combinatorial analysis of the stability of these approximations under resampling an edge.
