PET scans are a big deal in medicine. They help doctors see inside the body. But sometimes, the pictures come out blurry. This happens because tiny light particles, called gamma photons, bounce around. They hit different spots than they should. This is called inter-crystal scattering, or ICS for sho
Fake news spreads like wildfire on social media. It's not just one person sharing a false story. It's a group of people, a community, working together. These communities are not static. They change over time. People join, leave, and new groups form. This makes it hard to track how fake news spreads.
People are using smart computers to make new medicines. These computers can look at tiny parts of medicine and guess how they work. They can also make new medicines that might help people feel better. First, the computers learn about medicines. They look at how medicines are built. Then, they guess
Video analytics are a big deal, but sending high-quality videos from edge devices to the cloud can be costly. It's not just about the money; it's also about the power and bandwidth used. So, how can we make this process more efficient? Enter LtC, a smart framework that teams up the video source and
AI systems are often tricked by sneaky inputs called adversarial examples. These inputs are tweaked just enough to confuse AI models, but not enough for humans to notice. The tricky part is making these examples work well on different AI systems without being too obvious. A new method called Diff-A
Ever wondered how scientists figure out what's in our bodies? It's not as easy as it sounds. They often use a method called metabolomics. This involves looking at tiny amounts of chemicals, or metabolites, in our cells. The problem is, there are lots of unknown metabolites out there. And without a r
Modern buildings are becoming more intelligent, with sensors monitoring various aspects like temperature and air quality. However, these sensors often fail to capture all necessary data, leading to gaps that can disrupt building management efforts. Researchers recently developed a clever solution t
Brain-inspired computers, called Spiking Neural Networks (SNNs), are great for low-power devices like wearables and sensors. But one key part, the leaky time constant (LTC), hasn't been fully studied. The LTC helps these computers process information over time. Scientists tested how changing the LTC
In the world of medical image analysis, a new tool called X-UNet is making waves. It's designed to help doctors and researchers better understand medical images by focusing on important details and patterns. X-UNet uses a special technique called the CFGC module. This module helps the tool to look
Time-based networks, like social media or online shopping platforms, show how connections change over time. Lately, scientists have focused on creating better models to understand these networks. But there's a catch: they haven't paid much attention to the quality of the "wrong" examples used to tra
