Open AccessPerformance analysis and modelling of circular jets aeration in an open channel using soft computing techniques
Dissolved oxygen (DO) is an important parameter in assessing water quality. The reduction in DO concentration is the result of eutrophication, which degrades the quality of water. Aeration is the best way to e...

Open AccessGS-DeepNet: mastering tokamak plasma equilibria with deep neural networks and the Grad–Shafranov equation
The force-balanced state of magnetically confined plasmas heated up to 100 million degrees Celsius must be sustained long enough to achieve a burning-plasma state, such as in the case of ITER, a fusion reactor...

Open AccessQBO deepens MJO convection
The underlying mechanism that couples the Quasi-Biennial Oscillation (QBO) and the Madden-Julian oscillation (MJO) has remained elusive, challenging our understanding of both phenomena. A popular hypothesis ab...

Open AccessDeep learning-based incoherent holographic camera enabling acquisition of real-world holograms for holographic streaming system
While recent research has shown that holographic displays can represent photorealistic 3D holograms in real time, the difficulty in acquiring high-quality real-world holograms has limited the realization of ho...

Open AccessDiffraction-engineered holography: Beyond the depth representation limit of holographic displays
Holography is one of the most prominent approaches to realize true-to-life reconstructions of objects. However, owing to the limited resolution of spatial light modulators compared to static holograms, reconst...

Open AccessDynamic coordination of two-metal-ions orchestrates λ-exonuclease catalysis
Metal ions at the active site of an enzyme act as cofactors, and their dynamic fluctuations can potentially influence enzyme activity. Here, we use λ-exonuclease as a model enzyme with two Mg2+ binding sites and ...
