Hausdorff dimensions of irreducible Markov hom tree‐shifts
Journal of the London Mathematical Society, Volume 111, Issue 6, June 2025.Abstract This paper features a Cramér's theorem for finite‐state Markov chains indexed by rooted d$d$‐trees, obtained via the method of types in the classical analysis of large deviations. Along with the theorem comes two applications: an almost‐sure type convergence of sample means and a formula for the Hausdorff dimension of the symbolic space ...

Concentration and Model Selection Consistency of the Group Lasso for α$$ \alpha $$‐Mixing Errors
Stat, Volume 14, Issue 1, March 2025.ABSTRACT The group lasso in linear regression models is studied for α$$ \alpha $$‐mixing subexponential errors. Nonasymptotic guarantees are provided for the estimation error of the sparse coefficient vector and the associated predictions for the high‐dimensional regime where the number of regressors can grow much faster than the sample size.

Central limit theorem in disordered Monomer‐Dimer model
Random Structures &Algorithms, Volume 66, Issue 1, January 2025.Abstract We consider the disordered monomer‐dimer model on general finite graphs with bounded degrees. Under the finite fourth moment assumption on the weight distributions, we prove a Gaussian central limit theorem for the free energy of the associated Gibbs measure with a rate of convergence. The central limit theorem continues to hold under a nearly

Typical Structure of Hereditary Graph Families. I. Apex‐free Families
Random Structures &Algorithms, Volume 66, Issue 1, January 2025.ABSTRACT A family of graphs ℱ$$ \mathcal{F} $$ is hereditary if ℱ$$ \mathcal{F} $$ is closed under isomorphism and taking induced subgraphs. The speed of ℱ$$ \mathcal{F} $$ is the sequence {|ℱn|}n∈ℕ$$ {\left\{|{\mathcal{F}}^n|\right\}}_{n\in \mathbb{N}} $$, where ℱn$$ {\mathcal{F}}^n $$ denotes the set of graphs in ℱ$$ \mathcal{F} $$ with the vertex ...

IET Information Security, Volume 2025, Issue 1, 2025.The current multikey fully homomorphic encryption (MKFHE) needs to add exponential noise in the distributed decryption phase to ensure the simulatability of partial decryption. Such a large noise causes the ciphertext modulus of the scheme to increase exponentially compared to the single‐key fully homomorphic encryption (FHE), further reducing the ...

Optimising Control Device Luring Strategies for Invasive Predator Control: A Modelling Approach
Ecology and Evolution, Volume 14, Issue 12, December 2024.Invasive predators pose a threat to native biodiversity, and their management is hindered by trap‐shyness. Using Bayesian estimation, researchers quantified trap‐shyness in wild brushtail possums, finding a large number of trap‐shy individuals with a low probability of trap interaction.

Boundary Strichartz estimates and pointwise convergence for orthonormal systems
Transactions of the London Mathematical Society, Volume 11, Issue 1, December 2024.Abstract We consider maximal estimates associated with fermionic systems. Firstly, we establish maximal estimates with respect to the spatial variable. These estimates are certain boundary cases of the many‐body Strichartz estimates pioneered by Frank, Lewin, Lieb and Seiringer.

Advanced Optical Materials, Volume 12, Issue 27, September 23, 2024.CsPbBr3 perovskite nanocrystal thin films display a distinctive Amplified Spontaneous Emission (ASE) behavior, where an anomalously shifted ASE band coexists with an excessive fluorescence background. This work shows that this behavior stems from four processes: reabsorption due to ground and excited state absorption, excitation of differently ...

Directed mean curvature flow in noisy environment
Communications on Pure and Applied Mathematics, Volume 77, Issue 3, Page 1850-1939, March 2024.Abstract We consider the directed mean curvature flow on the plane in a weak Gaussian random environment. We prove that, when started from a sufficiently flat initial condition, a rescaled and recentred solution converges to the Cole–Hopf solution of the KPZ equation.
