I agree. To me the scariest part is not the courting of the far right, it’s the willingness to participate in this febrile hallucinatory fiction. This is Alternative Facts land.

Strategic analysis of hydrogen market dynamics across collaboration models
The global energy landscape is experiencing a transformative shift, with an increasing emphasis on sustainable and clean energy sources. Hydrogen remains a promising candidate for decarbonization, energy storage, and as an alternative fuel. This study explores the landscape of hydrogen pricing and demand dynamics by evaluating three collaboration scenarios: market-based pricing, cooperative integration, and coordinated decision-making. It incorporates price-sensitive demand, environmentally fri…

ARSAR-Net: Adaptively Regularized SAR Imaging Network via Non-matrix-inversion ADMM
Deep unfolding networks have constituted an emerging method for synthetic aperture radar (SAR) imaging. However, baseline unfolding networks, when unfolded from the alternating direction method of multipliers (ADMM), lack generalization capability across scenes as the regularizers are empirically designed. In this study, we introduce a learnable regularizer to the unfolding network and create an adaptively regularized SAR imaging network (ARSAR-Net), which pursues generalization capability acro…

Very high-order accurate finite volume scheme for the streamfunction-vorticity formulation of incompressible fluid flows with polygonal meshes on arbitrary curved boundaries
Conventional mathematical models for simulating incompressible fluid flow problems are based on the Navier-Stokes equations expressed in terms of pressure and velocity. In this context, pressure-velocity coupling is a key issue, and countless numerical techniques and methods have been developed over the decades to solve these equations efficiently and accurately. In two dimensions, an alternative approach is to rewrite the Navier-Stokes equations regarding two scalar quantities: the streamfunct…

Regularizing Learnable Feature Extraction for Automatic Speech Recognition
Neural front-ends are an appealing alternative to traditional, fixed feature extraction pipelines for automatic speech recognition (ASR) systems since they can be directly trained to fit the acoustic model. However, their performance often falls short compared to classical methods, which we show is largely due to their increased susceptibility to overfitting. This work therefore investigates regularization methods for training ASR models with learnable feature extraction front-ends. First, we e…

Half-life determination of heavy ions in a storage ring considering feeding and depleting background processes
Heavy-ion storage rings have relatively large momentum acceptance which allows for multiple ion species to circulate at the same time. This needs to be considered in radioactive decay measurements of highly charged ions, where atomic charge exchange reactions can significantly alter the intensities of parent and daughter ions. In this study, we investigate this effect using the decay curves of ion numbers in the recent $^{205}$Tl$^{81+}$ bound-state beta decay experiment conducted using the Exp…
