New estimation methods for diagnostic classification models
British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract This paper introduces a new class of estimators for cognitive diagnosis models (CDMs) based on the Cressie–Read family of ϕ$$ \phi $$‐divergences. Focusing on the loglinear CDM (LCDM), for which joint maximum likelihood estimation (JMLE) has been shown to be consistent, we propose a joint minimum divergence estimation (JMDE) framework.

British Journal of Pharmacology, EarlyView.Background and Purpose Binding kinetics are essentially based on rate constants. Yet, this view has been challenged by the idea that ‘binding fluxes’ are dynamic and therefore more relevant. Those fluxes refer to the rate at which a target/receptor changes from one state into another through ligand/drug binding or a conformational change.

Is free trade good for renewable resources? Brander and Taylor redux
Canadian Journal of Economics/Revue canadienne d'économique, EarlyView.Abstract This paper generalizes the original Brander and Taylor model of open‐access renewable resource use and trade to address three common critiques. First, I introduce heterogeneity across agents in harvesting productivity to smooth out the model's extreme specialization patterns while maintaining its Ricardian structure and tractability. Second, I

Progressively Projected Newton's Method
Computer Graphics Forum, EarlyView.Abstract Newton's Method is widely used to find the solution of complex non‐linear simulation problems. To guarantee a descent direction, it is common practice to clamp the negative eigenvalues of each element Hessian prior to assembly—a strategy known as Projected Newton (PN)—but this perturbation often hinders convergence.

Survey on differential estimators for 3d point clouds
Computer Graphics Forum, EarlyView.Abstract Recent advancements in 3D scanning technologies, including LiDAR and photogrammetry, have enabled the precise digital replication of real‐world objects. These methods are widely used in fields such as GIS, robotics, and cultural heritage. However, the point clouds generated by such scans are often noisy and unstructured, posing challenges for ...
