The contrast in suspended particle dynamics at surface and near bottom on the river-dominated northern South China Sea shelf in summer: implication on physics and biogeochemistry coupling

open access: yesFrontiers in Marine Science, 2023
To understand the process-response relations among physical forcing and biogeochemical properties of suspended particles (SPs) in the river-dominated northern South China Sea shelf, a 5-day shipboard observation was conducted at a fixed location on the ...

Digital Adaptive Learning in Secondary Mathematics: A Qualitative Interview Study With Austrian Teachers on Perceptions, Needs, and Implementations

open access: yesJournal of Computer Assisted Learning, Volume 42, Issue 1, February 2026.
ABSTRACT Background One of the advances in learning with technology is digital adaptive learning (AL) materials for mathematics. Although empirical studies have shown the benefits of AL for learners and teachers, little research has been done on teachers' perceptions and needs of digital AL and their plans for implementation in mathematics classrooms ...

Explosive condensation in a mass transport model [PDF]

open access: yes, 2012
We study a far-from-equilibrium system of interacting particles, hopping between sites of a 1d lattice with a rate which increases with the number of particles at interacting sites.

When Cellulose Moves: Smart Sensors and Actuators

open access: yesAdvanced Materials Technologies, Volume 10, Issue 23, December 3, 2025.
This review highlights cellulose‐derived soft actuators alongside with cellulose‐based sensors. Emphasis is placed on their integration into multifunctional devices that couple sensing and actuation to mimic natural motion and adaptability. We also discuss the challenges of achieving robust, reversible, and multi‐stimuli‐responsive motion, and outline ...
