Forward and Adjoint Calculations of Gravitational Potential in Heterogeneous, Aspherical Planets

open access: yesEarth and Space Science, Volume 13, Issue 5, May 2026.
Abstract We have developed a computational package for the calculation of numerically exact internal and external gravitational potential, its functional derivatives and sensitivity kernels, in an aspherical, heterogeneous planet. We detail our implementation, utilizing a transformation of the Poisson equation into a spherical reference domain, as well

Global field trials show the advantages of beta regression compared with logit transformation and quasi‐likelihood for the analysis of percentage plant disease severity

open access: yesAnnals of Applied Biology, Volume 188, Issue 3, Page 904-916, May 2026.
Disease severity in crop protection field trials is commonly assessed as a proportion represented as a percentage. Traditional statistical analysis uses transformation to logit or angle. This study compares analyses based on the beta distribution and the quasi‐likelihood method with the logit transform using a large global data set of field trials ...

Detecting Critical Change in Dynamics Through Outlier Detection with Time‐Varying Parameters

open access: yesBritish Journal of Mathematical and Statistical Psychology, Volume 79, Issue 2, Page 237-262, May 2026.
Abstract Intensive longitudinal data are often found to be non‐stationary, namely, showing changes in statistical properties, such as means and variance‐covariance structures, over time. One way to accommodate non‐stationarity is to specify key parameters that show over‐time changes as time‐varying parameters (TVPs). However, the nature and dynamics of

Integrating ecological feedbacks across scales and levels of organization

open access: yesEcography, Volume 2026, Issue 5, May 2026.
In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.

Network Games With Triadic Interactions

open access: yesInternational Economic Review, Volume 67, Issue 2, Page 605-632, May 2026.
ABSTRACT We propose a model for network‐mediated interactions incorporating higher‐order relationships such as triadic interactions. The marginal utility of an individual's action depends explicitly on endogenous actions of multiple units. Conditions ensuring a unique Nash equilibrium are derived using a variational inequality approach. We estimate the

Regional cerebellar structural deficits distinguish psychostimulant‐free ADHD youth with and without familial risk for bipolar I disorder: a cross‐sectional morphometric analysis

open access: yesJournal of Child Psychology and Psychiatry, Volume 67, Issue 5, Page 766-776, May 2026.
Background Although attention‐deficit/hyperactivity disorder (ADHD) with familial risk for bipolar I disorder (BD) may represent a more severe illness conferring greater risk for developing BD, associated neurostructural substrates remain poorly understood.
