Ion dynamics and coherent structure formation following laser pulse self-channeling

, 2007
The propagation of a superintense laser pulse in an underdense, inhomogeneous plasma has been studied numerically by two-dimensional particle-in-cell simulations on a time scale extending up to several picoseconds.

Smart Denture with Embedded Thin‐Film Temperature Sensors Patterned by Femtosecond Laser Pulse for Elderly Healthcare

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
We demonstrate the direct‐laser patterning of a gold thin film on polymethyl methacrylate to fabricate a temperature sensor for dentures. The temperature sensor‐embedded smart dentures are evaluated in an oral environment, enabling in‐situ monitoring for elderly healthcare.

Ultrashort time to echo magnetic resonance techniques for the musculoskeletal system [PDF]

Quantitative Imaging in Medicine and Surgery, 2016
Magnetic resonance (MR) imaging has been widely implemented as a non-invasive modality to investigate musculoskeletal (MSK) tissue disease, injury, and pathology. Advancements in MR sequences provide not only enhanced morphologic contrast for soft tissues, but also quantitative biochemical evaluation.

Entropy‐Guided Convolutional Neural Network Classification of Sensor Signals for Real‐Time Surface Quality Monitoring in Direct Laser Interference Patterning

Advanced Intelligent Systems, EarlyView.
Neural‐network pipeline for real‐time DLIP surface‐quality monitoring: spectral entropy of WLI topographies is used to generate interpretable K‐means labels, which are transferred to time‐resolved photodiode traces. A compact dual‐input 1D‐CNN (signal + laser parameters) learns discriminative spatiotemporal features and predicts “OK/NOK” surface ...

Recent Trends in Metabolomics by NMR Spectroscopy

Angewandte Chemie International Edition, EarlyView.
AI tools were applied to analyze more than 5 000 publications indexed in Scopus (2018–2025), identifying key trends and research directions in NMR‐based metabolomics. The artificial intelligence‐assisted workflow classified papers into six main fields of application, human health, food and nutrition, veterinary science, plants, environment, and ...

Asymmetric Fe–Te Pairs Enhance Peroxymonosulfate Activation via Surface‐Bound Hydroxyl Radicals Pathways

Angewandte Chemie International Edition, EarlyView.
An asymmetric Fe–Te dual‐atom pair directs peroxymonosulfate activation toward long‐lived surface‐bound hydroxyl radicals through strong p–d hybridization. The resulting electronic asymmetry enables efficient pharmaceutical degradation and reveals a metal–metalloid pairing strategy for steering reactive oxygen species pathways in advanced oxidation ...

An in vivo imaging study of fascia thickness and muscle volume in the lower limb of healthy adult humans

Computer Methods in Biomechanics and Biomedical Engineering: Imaging & Visualization
Fascia is a connective tissue that influences movement and may play roles in muscle force transmission, pain sensation, and lymphatic function. To date, 3D imaging of fascia using MRI has not been achieved due to short T2* times of collagen-rich fascia ...
