In August, a guest on Tucker Carlson’s podcast said something that immediately caught his interest.
The United States faces a fundamental rift
“between heritage Americans and the new political class,” Auron MacIntyre, a columnist for Blaze Media, argued.
“Heritage Americans
—what are those?” Carlson asked.
“You could find their last names in the Civil War registry,” MacIntyre explained.
This ancestry matters, he said, because America is not “a collection o…

Light Field Super-Resolution: A Critical Review on Challenges and Opportunities
Advances in portability and low cost of plenoptic cameras have revived interest in light field imaging. Light-field imaging has evolved into a technology that enables us to capture richer visual information. This high-dimensional representation of visual data provides a powerful way to understand the scene, with remarkable improvement in traditional computer vision problems such as depth sensing , post-capture refocusing , material classification, segmentation, and video stabilization. Capturin…

Automated Code Development for PDE Solvers Using Large Language Models
Foundation models -- large language models (LLMs) in particular -- have become ubiquitous, shaping daily life and driving breakthroughs across science, engineering, and technology. Harnessing their broad cross-domain knowledge, text-processing, and reasoning abilities for software development, e.g., numerical libraries for solving partial differential equations (PDEs), is therefore attracting growing interest. Yet existing studies mainly automate case setup and execution for end users. We intro…

Radio Stars in the Era of New Observatories
An international conference Radio Stars in the Era of New Observatories was held at the Massachusetts Institute of Technology Haystack Observatory on 2024 April 17-19. The conference brought together more than 60 researchers from around the world, united by an interest in using radio wavelength observations to explore the physical processes that operate in stars (including the Sun), how stars evolve and interact with their environments, and the role of radio stars as probes of our Galaxy. Topic…

Twisting Signals for Joint Radar-Communications: An OAM Vortex Beam Approach
Orbital angular momentum (OAM) technology has attracted much research interest in recent years because of its characteristic helical phase front twisting around the propagation axis and natural orthogonality among different OAM states to encode more degrees of freedom than classical planar beams. Leveraging upon these features, OAM technique has been applied to wireless communication systems to enhance spectral efficiency and radar systems to distinguish spatial targets without beam scanning. L…

Nonreciprocal optical circuit switching
Directly switching optical signals outperforms conventional optoelectronic hardware in terms of cost, latency, and energy efficiency, and is expected to address the growing demand for data node capacity driven by the development of machine learning and artificial intelligence (AI) technologies. Therefore, optical circuit switching (OCS) technology has piqued widespread research interest in various technical solutions, including silicon photonics. However, silicon-based integrated OCS remains co…

Thermal Degradation Mechanisms and Stability Enhancement Strategies in Perovskite Solar Cells: A Review
Perovskite Solar Cells (PSCs) have garnered global research interest owing to their superior photovoltaic (PV) performance. The future of photovoltaic technology lies in PSCs since they can produce power with performance on par with the best silicon solar cells while being less expensive. PSCs have enormous potential; in just ten years, their efficiency increased from 3.8% to 25.2%, and research into new developments is still ongoing. Thermal instability is PSCs' main disadvantage, despite thei…
