This paper describes Unbend - a new method for measuring and correcting motions in cryo-EM images, with a particular emphasis on more challenging in situ samples such as lamella and whole cells. The ...

Abstract: It is challenging for active contour models (ACMs) to segment weak-edge and noisy images efficiently and accurately. To solve this problem, a novel ACM is proposed in this work. The proposed ...

Abstract: Accurate normalization is essential for artifacts-free quantitative 3D positron emission tomography (PET) imaging. The de facto method for PET normalization, component-based normalization, ...

You might use these apps every day, but have no idea what they collect. These 20 apps are quietly harvesting your location, contacts, photos, and more—here's what ...

Beijing Zhongke Journal Publising Co. Ltd. Heavy fermion materials have long attracted interest in condensed matter physics for hosting correlation-driven exotic quantum states. Remarkably, the oxide ...

From the moment we could look up to the skies, humanity has dreamt of what’s up there. And once we got there, how could we master it? And now that we’re there all the time, how can we use it? In 2025, ...

Marcel is a writer who is passionate about most movies and series. He will watch anything that's good. He is a content manager by day and a videographer when needed. Marcel used to work at a major ...

Although some functions can be accessed with the tool in this configuration, the fun really starts when you roll it in on itself, folding it into a Toblerone-ish shape. It can then be grasped like a ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Engineers at the UCLA Samueli School of Engineering introduced a framework for universal point spread function (PSF) engineering, enabling the synthesis of arbitrary spatially varying 3D PSFs using ...
