Abstract: Anomaly interference in the radiation pattern of an active phased array antenna (APAA) is an intractable problem, that affects the overall system performance. To overcome this problem, this ...

Eric Gutiérrez, 6th February 2026. A Python implementation of a 1-hidden layer neural network built entirely from first principles. This project avoids deep learning libraries (like TensorFlow or ...

The COVID-19 pandemic highlighted an urgent need for efficient, durable, and widely accessible vaccines. This prompted several important innovations in vaccine technology, and researchers continue to ...

Abstract: To address the degradation in radiation performance caused by external deformations in variable-curvature cylindrical conformal antenna arrays, this letter proposes a real-time beam pattern ...

Space, in military parlance, is “the ultimate high ground.” And for years, the Pentagon has mused about ways to orbit a radar from high above, to look down on adversary aircraft and catch them out in ...

This project contains implementations of simple neural network models, including training scripts for PyTorch and Lightning frameworks. The goal is to provide a modular, easy-to-understand codebase ...

Forbes contributors publish independent expert analyses and insights. Philip Maymin, a professor of analytics and AI, covers finance and AI. Is this a deep learning neural network, with blue inputs, ...

Visualizing neural connections in 3D with a new microscopy technique by C. Huygelen, Leiden University edited by Lisa Lock, reviewed by Robert Egan Editors' notes The GIST ...

As it does so, a 3D printer system prints a rigid back structure to the blanket array membrane. As it does so, the hard UV radiation of space rapidly cures the resin, making it hard. This means a ...

A high-resolution 3D model of Rano Raraku shows that the moai were created in many distinct carving zones. Instead of a top-down system, the statues appear to have been produced by separate family ...

Fig. 1 Neural array imaging system and its principle behind its ability to break the trade-off between aperture size, ffeld of view, and imaging quality. (a) The system consists of a metalens array, a ...
