Exploring the Elastic Properties of Interfacial Transition Zone in Concrete Materials Using an Ensemble Learning Approach

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Concrete materials consist of multiple phases with distinct mechanical properties, making it essential to accurately identify the mechanical behavior of both constituent phases and their interfaces for effective multiscale modeling. This study estimates the elastic properties of the interfacial transition zone using a machine learning (ML ...

Early Adolescent Cyberbullying Victimization, Learning Readiness, and Academic Achievement Among South Australian Students

open access: yesPsychology in the Schools, EarlyView.
ABSTRACT Cyberbullying is an increasingly researched topic in the field of adolescence, largely due to its pervasiveness and negative wellbeing outcomes for victims. However, existing literature in this area largely focuses on those aged above 13 years, despite evidence suggesting that early adolescents (ages 10–13) also experience victimization ...

Stanilov-Tsankov-Videv Theory

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2007
We survey some recent results concerning Stanilov-Tsankov-Videv theory, conformal Osserman geometry, and Walker geometry which relate algebraic properties of the curvature operator to the underlying geometry of the manifold.

Modeling General Asymptotic Calabi–Yau Periods

open access: yesFortschritte der Physik, EarlyView.
Abstract In the quest to uncovering the fundamental structures that underlie some of the asymptotic Swampland conjectures the authors initiate the general study of asymptotic period vectors of Calabi–Yau manifolds. The strategy is to exploit the constraints imposed by completeness, symmetry, and positivity, which are formalized in asymptotic Hodge ...

A Pharmacometric Workflow for Resolving Model Instability in Model Use‐Reuse Settings

open access: yesCPT: Pharmacometrics &Systems Pharmacology, EarlyView.
ABSTRACT The development of fit‐for‐purpose pharmacokinetic‐pharmacodynamic (PKPD) models based on clinical and pre‐clinical data is a critically important process in model informed drug development. This process is often hampered by modeling stability issues that are often multifactorial in nature and difficult to overcome, leading to protracted model
