CO₂ fluxes contrast between aquaculture ponds and mangrove forests and its implications for coastal wetland rehabilitation in Leizhou Peninsula, China
(2024)Agriculture, Ecosystems & EnvironmentCoastal wetlands have great potential to mitigate climate change. However, in recent decades, the construction of aquaculture ponds has degraded coastal habitats, especially mangroves. Meanwhile, the lack of synchronized monitoring of carbon dioxide (CO₂) fluxes in coastal ponds and mangroves hinders the promotion of carbon neutrality target through the implementation of coastal wetland rehabilitation. To address this issue, we deployed ...Journal Article -

Assembling a durable homologous-like heterojunction s-TiO₂@CaTiO₃ for photodegradation of atrazine through boosting charge migration with peroxymonosulfate reinforcement
(2024)Chemical Engineering JournalHeterojunctions present a promising avenue for improving charge separation in photocatalytic water purification processes. However, the multicomponent heterojunction interfaces often act as recombination centers for photogenerated carriers. Herein, a Ti-based homologous-like heterojunction was fabricated by in-situ growth of controllable CaTiO3 on sulfur-doped TiO2 (STCTO). This heterojunction exhibits outstanding performance in photocatalytic ...Journal Article -
HV geometry for signal comparison
(2024)Quarterly of Applied MathematicsIn order to compare and interpolate signals, we investigate a Riemannian geometry on the space of signals. The metric allows discontinuous signals and measures both horizontal (thus providing many benefits of the Wasserstein metric) and vertical deformations. Moreover, it allows for signed signals, which overcomes the main deficiency of optimal transportation-based metrics in signal processing. We characterize the metric properties of the ...Journal Article -
A Novel Construction of Distribution Function through Second-Order Polynomial Approximation in Terms of Particle Mass, Momentum and Energy
(2024)Advances in Applied Mathematics and MechanicsIn this paper, we propose a new way to construct the distribution function through the second-order polynomial approximation in terms of particle mass, momentum and energy. The new construction holds three distinguished features. First, the formulations are more concise as compared with the third-order truncated Hermite polynomial expansion which yields Grad's 13-moment distribution function; Second, all moments of the present distribution ...Journal Article -
Fabrication Procedures and Mechanical Supports of No-Insulation All-GdBCO Double Pancake Magnets in Liquid Helium
(2024)IEEE Transactions on Applied SuperconductivityThe no-insulation (NI) high-temperature superconductor (HTS) winding technique enables the fabrication of highly compact magnets with self-quench protection. NI pancake coils are implemented to develop a 28-T HTS magnet for the operation of a 792-GHz gyrotron, which is a microwave source for dynamic nuclear polarization nuclear magnetic resonance. To this end, three NI all-GdBCO double pancake (DP) magnets were fabricated using different ...Journal Article -
More realistic planetesimal masses alter Kuiper belt formation models and add stochasticity
(2024)IcarusMuch of the modern Kuiper belt is thought to be the result of Neptune's migration through a primordial belt of planetesimals, possibly interrupted by an instability amongst the giant planets. While most prior work has employed massless test particles to study this Kuiper belt formation process, we perform simulations here that include the gravitational effects of the primordial planetesimal belt consisting of ∼105 massive bodies. In our ...Journal Article -
Demonstration of a successful soft chemical stimulation in a geothermal sandstone reservoir in Mezőberény (Hungary)
(2024)GeothermicsGeothermal energy projects often lack sufficient permeability for a sustainable operation. If natural permeability is low, it can be enhanced by stimulation treatments. These can be of thermal, hydraulic or chemical nature. The challenge is to stimulate the reservoir successfully and at the same time to do it in an environmentally safe way. This is called soft stimulation and was extensively tested in the context of the EU-Horizon2020 ...Journal Article -
Molecular dynamics investigation of gold nanoparticle coalescence under realistic gas-phase synthesis conditions
(2024)Journal of Aerosol ScienceDependence of nanoparticle (NP) coalescence on various physical parameters (e.g., temperature, number of NPs, NP size, orientation, crystallinity, shape, or composition, etc.) is a very active field of investigation. However, most computational studies on NP coalescence to date are performed in vacuum, with only a handful of studies taking gas pressure into account and even fewer doing a systematic analysis. This is due to two reasons: ...Journal Article -
Lifted algorithms for symmetric weighted first-order model sampling
(2024)Artificial IntelligenceWeighted model counting (WMC) is the task of computing the weighted sum of all satisfying assignments (i.e., models) of a propositional formula. Similarly, weighted model sampling (WMS) aims to randomly generate models with probability proportional to their respective weights. Both WMC and WMS are hard to solve exactly, falling under the #P-hard complexity class. However, it is known that the counting problem may sometimes be tractable, ...Journal Article
