Mediation Analysis With Bayesian Nonlinear Joint Models: Evaluation of the Treatment Causal Pathways Between Tumor Growth Kinetics and Overall Survival

Statistics in Medicine, Volume 45, Issue 13-14, June 2026.
ABSTRACT Understanding the mechanisms through which anti‐cancer treatments influence survival is central to improving drug development and evaluation. In this work, we develop a Bayesian joint modeling framework for mediation analysis to quantify the extent to which tumor size dynamics mediate the effect of treatment on overall survival (OS). Our model

Quality Control of Magnetotelluric Impedance Inversion via Self‐Supervised Learning Based on Data Continuity of Nyquist Diagrams

Geophysical Prospecting, Volume 74, Issue 5, June 2026.
ABSTRACT Magnetotelluric (MT) data are often contaminated by electromagnetic (EM) noise, making quality control (QC) essential for reliable inversion. Conventional manual time‐domain QC processes are labour‐intensive, and some noise inevitably remains after processing, necessitating complementary processing in the frequency domain to address the ...

SURFACES OF REVOLUTION WITH POINTWISE 1-TYPE GAUSS MAP IN MINKOWSKI 3-SPACE

Taiwanese Journal of Mathematics, 2009
We study the rational surfaces of revolution in Minkowski 3-space and characterize them with pointwise 1-type Gauss map. In this article, we give a complete classification of rational surfaces of revolution in Minkowski 3-space with pointwise 1-type Gauss map and provide new examples of cones in Minkowski 3-space.

Trait coevolution and causal inference using generalized dynamic phylogenetic models

Methods in Ecology and Evolution, Volume 17, Issue 6, Page 1818-1836, June 2026.
Abstract Phylogenetic comparative methods are widely used to study trait coevolution across biological and cultural domains. The most common methods are phylogenetic generalized linear (mixed) models, phylogenetic path analysis, Pagel's ‘discrete’ method and Ornstein–Uhlenbeck models. While some frameworks like generalized linear mixed models are quite

Towards the boundary of the fine curve graph

Journal of Topology, Volume 19, Issue 2, June 2026.
Abstract The fine curve graph was introduced as a geometric tool to study homeomorphisms of surfaces. In this paper, we study the Gromov boundary of this space and the local topology near points associated with certain foliations and laminations. We then give several applications including finding dynamically explicit elements with positive stable ...

On the Gauss map of minimal Lorentzian surfaces in 4-dimensional semi-Riemannian space forms with index 2 [PDF]

, 2017
In this paper, we study minimal Lorentzian surfaces with finite type Gauss map in 4-dimensional semi-Riemannian space forms with index of 2. First, we give the complete classification of Lorentzian surfaces in the semi-Euclidean space E-2(4) with ...

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

Earth 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

Extension of Eigenvalue Problems on Gauss Map of Ruled Surfaces [PDF]

, 2018
A finite-type immersion or smooth map is a nice tool to classify submanifolds of Euclidean space, which comes from the eigenvalue problem of immersion.
