Fitting genetic models using Markov Chain Monte Carlo algorithms with BUGS [PDF]
, 2006 Maximum likelihood estimation techniques are widely used in twin and family studies, but soon reach computational boundaries when applied to highly complex models (e.g., models including gene-by-environment interaction and gene-environment correlation ...

Language Learning, Volume 76, Issue 1, Page 176-210, March 2026.Abstract We employed structural priming to test whether targeted exposure to unambiguous form–meaning mappings led to learning of noncanonical word orders, specifically in object relative clauses, among 165 low‐to‐intermediate‐level L1 German L2 learners of English.

HELMERT TRANSFORMATION ON THE CASE OF GAUSS-KRÜGER AND UTM
Contemporary Theory and Practice in Construction, 2019 <jats:p>Globally, maps are our primary source of comprehensive information about the shape, size and arrangement of Earth features. Maps are the only way we can get a unique and comprehensive view of the world. Unfortunately, globally, all maps are somehow deformed, affecting our perception and understanding of the ...

Stabilizing Inference in Dirichlet Regression via Ridge‐Penalized Model
Statistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 1, February 2026.ABSTRACT We propose a penalized Dirichlet regression framework for modeling compositional data, using a softmax link to ensure that the mean vector lies on the simplex and to avoid log‐ratio transformations or zero replacement. The model is formulated in a GLM‐like setting and incorporates an ℓ2$$ {\mathrm{\ell}}_2 $$ (ridge) penalty on the regression ...

Using the Helmert-Transformation to Reduce Dimensionality in a Mixed Model: Application to a Wage Equation with Worker and Firm Heterogeneity [PDF]
A model for matched data with two types of unobserved heterogeneity is considered – one related to the observation unit, the other to units to which the observation units are matched.

Random Triangle Theory with Geometry and Applications
, 2015 What is the probability that a random triangle is acute? We explore this old question from a modern viewpoint, taking into account linear algebra, shape theory, numerical analysis, random matrix theory, the Hopf fibration, and much much more.

Reduced-Dynamic Precise Orbit Determination Based on Helmert Transformation
, 2008 Four fundamental approaches in the Precise Satellite Orbit Determination (POD) are Dynamic POD, Reduced-Dynamic POD, Kinematic POD, and Reduced-Kinematic POD (Svehla & Rothacher, 2003, Liu et al. 2004). Generally, two kinds of information are considered: dynamic parameters and kinematic factors. In the dynamic method, the orbit precision mainly depends

Adjusting a 2D Helmert transformation within a Gauss–Helmert Model with a singular dispersion matrix where BQ is of smaller rank than B [PDF]
Acta Geodaetica et Geophysica, 2016 The case of a singular dispersion matrix within the Gauss–Helmert Model has been considered before, most recently even allowing the rank of BQ to be smaller than the rank of B. In this contribution the emphasis is shifted towards an illuminating example, the 2D Helmert transformation.

The urgency of genetic decline in New Brunswick butternut, Juglans cinerea L.
PLANTS, PEOPLE, PLANET, Volume 8, Issue 1, Page 290-300, January 2026.Butternut is yet another North American tree species undergoing rapid mortality due to the globalization of forest pathogens. Pairing tree health surveys and genetic diversity metrics, we captured a 7‐year snapshot of butternut's path to extirpation from its distinct range in New Brunswick, Canada.
