Leveraging Metamaterial‐Inspired Wireless Resonator for Reliable Quantitative MRI at 1.5T: Linearity, Bias, and Repeatability Assessment

Advanced Physics Research, EarlyView.
This study designed a nonlinear‐response metamaterial‐inspired wireless resonator (MWR) and systematically evaluated the feasibility of using MWR for quantitative magnetic resonance imaging (qMRI), including T1/T2 mapping, apparent diffusion coefficient, and proton density fat fraction.

Deciphering the Palimpsest: Chronological Uncertainty and the Interpretation of Mining Landscapes at Písečný vrch (Czech Republic)

Archaeological Prospection, EarlyView.
ABSTRACT We investigated the Písečný vrch (Czech Republic), a site exploited for quartz mining in both prehistoric times and the 20th century. Due to their morphological similarity across all mining periods, the differentiation between pits with archaeological potential and recent ones is challenging.

The epistemic ceiling: Veteran practitioners' perspectives on primary qualification entry standards for teaching secondary mathematics in Scotland

British Educational Research Journal, EarlyView.
Abstract This paper presents an exploratory analysis of contemporary curricular and professional qualification policies in the Scottish education system, focusing on minimum qualification thresholds for mathematics teaching. The study examines how veteran secondary mathematics practitioners perceive the structural and pedagogical implications of using ...

Prediction of experimental excited‐state absorption spectra by using vibronic transition calculations: Its practical application to a π‐conjugated molecule

Bulletin of the Korean Chemical Society, EarlyView.
Excited‐state absorption (ESA) spectra are notoriously hard to compute. We show that routine DFT and TDDFT vibronic transition calculations reproduce the vibronic band shapes and positions of azulene's experimental ESA spectrum, providing a practical route to assign ESA bands to specific electronic transitions and vibrational modes.

Ensemble‐based soil liquefaction assessment: Leveraging CPT data for enhanced predictions

Civil Engineering Design, Volume 7, Issue 1, Page 23-35, March 2025.
Abstract This study focuses on predicting soil liquefaction, a critical phenomenon that can significantly impact the stability and safety of structures during seismic events. Accurate liquefaction assessment is vital for geotechnical engineering, as it informs the design and mitigation strategies needed to safeguard infrastructure and reduce the risk ...
