A Multiple Imputation Approach to Distinguish Curative From Life‐Prolonging Effects in the Presence of Missing Covariates

open access: yesBiometrical Journal, Volume 68, Issue 3, June 2026.
ABSTRACT Medical advances have increased cancer survival rates and the possibility of finding a cure. Hence, it is crucial to evaluate the impact of treatments both in terms of cure and prolongation of survival. To achieve this, we may use a Cox proportional hazards cure model.

Cultivating Creative Potential: A Constraints‐Based Framework for Movement Exploration Instructions

open access: yesThe Journal of Creative Behavior, Volume 60, Issue 2, June 2026.
ABSTRACT How constraints affect individuals' creative potential interests many scientific fields. Education, especially after 2000, actively supports creativity promotion, with creativity occupying a prominent place in Physical Education (PE) curricula of many countries.

Mapping Immunity With Cutting‐Edge Spatial Biology and Tissue Cytometry Innovations

open access: yesMedComm, Volume 7, Issue 6, June 2026.
This review explores how spatial biology integrates multiplexed imaging and tissue cytometry to reveal immune organization within native tissue contexts. ABSTRACT The immune system operates within organized tissue landscapes, where spatial relationships between cells shape the nature and outcome of immune responses.

Contemporaneous threshold autoregressive models: estimation, testing and forecasting [PDF]

open access: yes
This paper proposes a contemporaneous smooth transition threshold autoregressive model (C-STAR) as a modification of the smooth transition threshold autoregressive model surveyed in Teräsvirta (1998), in which the regime weights depend on the ex ante ...

Estimating Components in Finite Mixtures and Hidden Markov Models [PDF]

open access: yes
When the unobservable Markov chain in a hidden Markov model is stationary the marginal distribution of the observations is a finite mixture with the number of terms equal to the number of the states of the Markov chain.

Analysis and dynamically consistent nonstandard discretization for a rabies model in humans and dogs [PDF]

open access: yes, 2016
Rabies is a fatal disease in dogs as well as in humans. A possible model to represent rabies transmission dynamics in human and dog populations is presented.

Social movements and the synecdoche problem

open access: yesNoûs, Volume 60, Issue 2, Page 385-412, June 2026.
Abstract Social movements are central to our contemporary understanding of social change. Accordingly, we should want to be able to say what it is that makes social movements special; that is, to say what it is that movements in their entirety have that random samples of people and organizations within the movement do not have.

Generalized free wreath products and their operator algebras

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 6, June 2026.
Abstract We develop a new approach on free wreath products, generalizing the constructions of Bichon and of Fima‐Pittau. We show stability properties for certain approximation properties such as exactness, Haagerup property, hyperlinearity, and K‐amenability. We study qualitative properties of the associated von Neumann algebra: factoriality, primeness,

Stability and uniqueness of bounded weak solutions to triangular degenerate cross‐diffusion systems

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 6, June 2026.
Abstract The continuous dependence on the initial data and consequently the uniqueness of bounded weak solutions to a class of triangular reaction‐cross‐diffusion equations is shown. The class includes two‐species doubly degenerate equations for nutrient taxis models describing the response of bacteria to nutrient conditions.

NP-optimal kernels for nonparametric sequential detection rules [PDF]

open access: yes
An attractive nonparametric method to detect change-points sequentially is to apply control charts based on kernel smoothers. Recently, the strong convergence of the associated normed delay associated with such a sequential stopping rule has been studied
