SigmaFormer: Augmenting transformer encoders with COSMO sigma profiles for pure component property prediction

open access: yesAIChE Journal, EarlyView.
Abstract Transformer‐based molecular models pretrained on SMILES strings demonstrate strong performance in property prediction. However, these model often lack explicit integration of molecular surface charge distributions that govern intermolecular interactions such as hydrogen bonding and polarity.

Decoding Tattoo and Permanent Makeup Pigments: Linking Physicochemical Properties to Absorption, Distribution, Metabolism, and Elimination Profiles Using Quantitative Structure–Activity Relationship (QSAR)‐Based New Approach Methodologies (NAMs)

open access: yesAdvanced Intelligent Discovery, EarlyView.
This study applies QSAR‐based new approach methodologies to 90 synthetic tattoo and permanent makeup pigments, revealing systemic links between their physicochemical properties and absorption, distribution, metabolism, and elimination profiles. The correlation‐driven analysis using SwissADME, ChemBCPP, and principal component analysis uncovers insights

Large Language Model‐Based Chatbots in Higher Education

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
The use of large language models (LLMs) in higher education can facilitate personalized learning experiences, advance asynchronized learning, and support instructors, students, and researchers across diverse fields. The development of regulations and guidelines that address ethical and legal issues is essential to ensure safe and responsible adaptation

Characterizing the Dynamical Complexity Underlying Meditation

open access: yesFrontiers in Systems Neuroscience, 2019
Over the past 2,500 years, contemplative traditions have explored the nature of the mind using meditation. More recently, neuroimaging research on meditation has revealed differences in brain function and structure in meditators.

Note on ignition by a hot catalytic surface

open access: yes, 1981
In a previous paper [1], we applied asymptotic methods based on large values of the nondimensional activation temperature to study ignition of a reactive material, semi-infinite in extent, subjected to a step increase in temperature at its planar surface.

Transition From Primary to Secondary School: Igniting Attendance and Engagement Among Aboriginal and Torres Strait Islander Students Through National Policy Reform

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT Australia's Closing the Gap reform aims to address disparities experienced by Aboriginal and Torres Strait Islander peoples. There are specific targets focussed on key educational transitions; yet, the transition to secondary education is not a targeted priority.
