A semi-Markov model for price returns
, 2011 We study the high frequency price dynamics of traded stocks by a model of returns using a semi-Markov approach. More precisely we assume that the intraday return are described by a discrete time homogeneous semi-Markov process and the overnight returns ...

Journal of Field Robotics, Volume 43, Issue 2, Page 1130-1151, March 2026.ABSTRACT We present a comprehensive teleoperation framework for electric vehicle (EV) battery cell handling, integrating haptic feedback, extended reality (XR) visualization, and task‐parameterized Gaussian mixture regression (TP‐GMR) for adaptive, real‐time trajectory generation.

Random Structures &Algorithms, Volume 68, Issue 2, March 2026.ABSTRACT We study the contact process on the long‐range percolation cluster on ℤ$$ \mathbb{Z} $$ where each edge ⟨i,j⟩$$ \left\langle i,j\right\rangle $$ is open with probability |i−j|−s$$ {\left|i-j\right|}^{-s} $$ for s>2$$ s>2 $$. Using a renormalization procedure, we apply the Peierls‐type argument to prove that the contact process dies out if the ...

A survey of generalized inverses and their use in stochastic modelling [PDF]
, 2000 In many stochastic models, in particular Markov chains in discrete or continuous time and Markov renewal processes, a Markov chain is present either directly or indirectly through some form of embedding.

Relaxation patterns and semi-Markov dynamics
, 2018 Exponential relaxation to equilibrium is a typical property of physical systems, but inhomogeneities are known to distort the exponential relaxation curve, leading to a wide variety of relaxation patterns.

Equine Veterinary Journal, Volume 58, Issue 2, Page 533-548, March 2026.Abstract Background Strangles (Streptococcus equi infection) remains endemic in the UK, with ~300 laboratory diagnoses annually. Sub‐clinically infected long‐term carriers are considered a key driver of endemicity. Analysing genomes of circulating strains could provide valuable transmission insights of this pathogen.

International Wound Journal, Volume 23, Issue 3, March 2026.ABSTRACT The financial burden of diabetes‐related foot disease (DFD) in Australia remains inadequately understood. This study aimed to explore the direct costs and resource utilisation associated with DFD management, incorporating insights from healthcare professionals actively involved in the treatment of individuals with DFD.

Robust adaptive efficient estimation for a semi-Markov continuous time regression from discrete data
, 2019 In this article we consider the nonparametric robust estimation problem for regression models in continuous time with semi-Markov noises observed in discrete time moments. An adaptive model selection procedure is proposed.

Journal of Flood Risk Management, Volume 19, Issue 1, March 2026.ABSTRACT Roads are ecologically sensitive infrastructure that are highly susceptible to flooding, which can impair their functionality, serviceability, and durability. Existing assessment methods are often subjective or lack the ability to incorporate domain‐specific knowledge. Therefore, approaches that integrate expert‐driven prioritization with data‐

Advanced Science, Volume 13, Issue 8, 9 February 2026.Integrated omics analysis of matched primary and liver metastatic NPC tumors reveals a unique NOTCH1+ CSC subpopulation exhibiting enhanced stemness properties and tumorigenic capacity. With in vitro and in vivo assays, exosomal transfer of tumor‐derived FTO from NOTCH1+ cells to the endothelium promotes vascular permeability and metastatic potential ...
