UCLA mathematics professor developed key numerical algorithm used to reconstruct image of black hole

April 15, 2019|UCLA Newsroom, College of Mathematics|

UCLA mathematics professor Stan Osher, Cognitech Inc CEO Leonid Rudin and then PhD student Emad Fatemi, now sadly deceased, created a numerical algorithm that was instrumental in reconstructing the cleaned up image of the black hole captured in April 2017. Their work has been cited as the key regularization function in sparse modeling that has been applied to astronomical imaging (Akiyama et al. 2017) .

Study reveals key details about bacterium that increases risk for stomach cancer

March 25, 2019|UCLA Newsroom, CNSI News|

More than half of the people in the world host colonies of a bacterium called Helicobacter pylori in their stomachs.

Although it’s harmless to many, H. pylori can cause stomach cancer as well as ulcers and other gastric conditions. Doctors tend to prescribe multiple antibiotics to defeat the microbe, but that strategy can lead to antibiotic-resistant superbugs.

Now, a finding by UCLA scientists may lead to a better approach. The researchers have determined the molecular structure of a protein that enables H. pylori to stay alive in the stomach, and elucidated the mechanism by which that protein works.

Z. Hong Zhou, the study’s corresponding author and a UCLA professor of microbiology, immunology and molecular genetics, said the findings answer questions that have been sought ever since 2005, when two Australian scientists won a Nobel Prize for their discovery of H. pylori and its role in gastritis and peptic ulcer disease.

Imec to install high NA EUV imaging and attosecond analytical lab to probe lithography down to 8nm pitch

February 26, 2019|IMEC|

Today, imec, a world-leading research and innovation hub in nanoelectronics and digital technologies, and KMLabs, pioneers and world leaders in ultrafast laser and EUV technology, announce a joint development to create a real-time functional imaging and interference lithography laboratory. This lab will enable imaging in resist on 300mm wafers down to an unprecedented 8nm pitch. Additionally, it will enable time-resolved nanoscale characterization of complex materials and processes, such as photoresist radiation chemistry, two-dimensional materials, nanostructured systems and devices, emergent quantum materials.

Electronic activity previously invisible to electron microscopes revealed at UCLA

October 29, 2018|UCLA Newsroom|

New imaging technique may lead to improved functionality of devices such as PCs, smartphones.

The chips that drive everyday electronic gadgets such as personal computers and smartphones are made in semiconductor fabrication plants. These plants employ powerful transmission electron microscopes. While they can see physical structures smaller than a billionth of a meter, these microscopes have no way of seeing the electronic activity that makes the devices function. That may soon change, thanks to a new imaging technique developed by UCLA and University of Southern California researchers. This advance may enable scientists and engineers to watch and understand the electronic activity inside working devices, and ultimately improve their functionality.

The study, which was published online in Physical Review Applied, was led by Chris Regan, UCLA professor of physics and astronomy and a member of the California NanoSystems Institute.

YouTube: 2018 Governor Awards for High Impact Research Winner

October 5, 2018|CO-LABS YouTube Channel|

Friday, October 5, 2018 – Last night CO-LABS presented JILA’s ultrafast imaging team, led by Fellows Margaret Murnane and Henry Kapteyn, the 2018 Governor’s Award for High-Impact Research.

Murnane and Kapteyn were honored for their work in revolutionizing ultrafast and nanoscale imaging through the research and development of tabletop x-ray sources. These advancements enable real-time imaging of the structure, chemistry, and dynamics of materials at the level of small collections of atoms. The applications range from improving semiconductor devices and magnetic storage to understanding the fundamental physics and chemistry of complex materials. By designing, developing, and eventually enabling the availability of this technology through KM-Labs, Murnane and Kapteyn have enabled many curious researchers to further their discoveries.

Paper on diffractive optics shows 3D holograms become reconfigurable by computer

October 4, 2018|Opli.net|

Diffraction refers to a variety of phenomena occurring when a wave encounters an obstacle and bends around it. Diffractive optics are widely used today in imaging, holography, microscopy and manufacturing. Previous work has shown that extending diffractive optics from two dimensions to three dimensions enables new functionality and improves system performance. The paper suggests a way to make the two-dimensional waves three-dimensional in real time with a simple modification to existing devices controlled with a computer.
