High Relative Accuracy Computations With Covariance Matrices of Order Statistics

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In many statistical applications, numerical computations with covariance matrices need to be performed. The error made when performing such numerical computations increases with the condition number of the covariance matrix, which is related to the number of variables and the strength of the correlation between the variables. In a recent work,

Robust Linearization and Eigenvalue Analysis of General Complex Constrained Multibody Systems

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The derivation of linearized equations and subsequent eigenvalue analysis is the basis for tasks such as frequency‐domain response analysis, control design, and stability assessment for mechanical systems. However, for general multibody systems with redundant or nonholonomic constraints, practical challenges persist in achieving numerically ...

A Surrogate Model for Stability Assessment of Two‐Layered Cohesive Slopes

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This paper introduces a novel surrogate model for rapid stability evaluation of two‐layered cohesive slopes under undrained conditions. The model eliminates the need for iterative calculations and slip surface searches, allowing for fast and accurate stability assessments without reliance on advanced numerical tools. The formulation is derived

A Quantitative Approach to Record Skeletal Manifestations of Leprosy and Its Application to St Mary Magdalen Leprosarium, Winchester

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT This paper presents and tests a new method for publishing and diagnosing leprosy‐related skeletal lesions while making available the leprosy‐related demographic data and pathology for St Mary Magdalen, Winchester (MMW). This method can facilitate interstudy comparisons of leprosy prevalence and severity by improving data comparability.

Engaging people in educational processes that foster environmentally valuable outcomes: A synthesis of key findings across eight systematic reviews

People and Nature, EarlyView.
Abstract Alongside the rise of the evidence‐based conservation movement over the past 20 years, environmental education (EE) has emerged as a worthwhile strategy to achieve conservation goals. EE can help develop the societal attitudes, knowledge, skills, behaviours and norms that address conservation and environmental challenges and build deeper ...

Main‐chain polyfullerenes: Taking fullerene to the next dimension

Polymer International, EarlyView.
This short review appraises main‐chain polyfullerenes. Their slow development over 30 years has suddenly boomed with a rapid growth due to exciting developments in solar energy. Abstract This mini‐review gives an overview of the development, chemistry, properties and applications of main‐chain polyfullerenes.
