HydroTFT: a cross-basin attention model for multi-horizon rainfall–runoff prediction
Streamflow prediction is essential for water resources management, flood forecasting, and climate resilience. Long short-term memory (LSTM) networks have advanced large-sample hydrology through cross-basin learning, but their recurrent architectures have limited ability to capture long-range temporal dependencies, particularly for medium-range forecasting. Meanwhile, exist…

Modeling flow and mass transfer within hollow fiber packaging for gas separation
Hollow fiber membrane modules are used for gas purification by their selective permeation properties. Intensification of the process to minimize the retentate loss and gas pressure involves optimization at various scales. In this work, we outline a numerical investigation of the gas separation performance at the scale of fiber bundles and its impact on module performance.…

Thermally controlled absorber for enhanced point-source CO2 capture: Scaling up the process intensification packing technology
This work describes a pilot-scale, thermally controlled gas–liquid absorption column designed for point-source carbon dioxide (CO₂) capture, featuring a 4-m tall, 0.3-m diameter absorber with a capacity of up to 1 t of CO₂ per day. Flue-gas conditions are simulated using a natural gas-fired power generation engine. A key advancement is the integration of a 3D-printed proce…

Bridging Two Worlds: Introducing the Software Engineering and Scientific Computing Department
Scientific discovery increasingly depends on computing and software. Yet the practices used to develop scientific software often differ markedly from those in professional software engineering. To help bridge this gap, IEEE Computing in Science & Engineering (CiSE) is merging its existing Software Engineering and Scientific Programming departments into a unified department…

Implicit Neural Representation to Improve the Resolution of 3D Electrical Resistivity
Electrical resistivity tomography (ERT) is a subsurface imaging geophysical technique. Traditional ERT inversion methods, such as smoothness-constrained least-squares approaches, often suffer from discretization artifacts when reconstructing electrical resistivity from resistance measurements. To address the limitations of conventional ERT inversion, this study introduces…

From Lumped to Spatially Distributed Hydrologic Modeling: A Data‐Driven Framework Evaluated Across North American Catchments
Data-driven rainfall–runoff models have advanced rapidly, yet the majority of large-scale applications still rely on lumped inputs that smooth out spatial variability in precipitation, temperature, and landscape properties. This simplification can introduce substantial biases in flood peaks, hydrograph timing, and water balance estimates. Here, we develop a deep learning f…
