Scientists have pushed current supercomputing power to the limit looking for that improved efficiency, but the arrival of exascale computing within the next few years will allow them to take this quest to the next level. The project will combine analytical simulation with machine learning and data mining to discover new materials.

The collaboration is using software developed by Berkeley Lab scientists to predict excitation properties in potential photovoltaic solar cell materials. The software, BerkeleyGW, is a materials science simulation package that can predict the excited-state properties of materials, which is how a material responds to a stimulant such as a photon coming into it.

BerkeleyGW is considered one of the most accurate quantum mechanical simulations for data acquisition. Solar cells convert photons from the sun into electricity by absorbing photons and generating a current of electrons. Usually one photon is converted into one electron. The Carnegie Mellon collaboration is looking for materials that can undergo singlet fission, a process by which one photo-generated singlet exciton photon is converted into two triplet excitons, increasing the current being released.

The goal of the research is to find the rare materials that can undergo single fission to improve solar cell efficiency. Attempting to find these types of materials experimentally is an impossible task—researchers liken it to finding a needle in a haystack. The computational cost is still steep, but improving code performance can help lessen the load. By optimizing parallelization and exploiting accelerators such as GPUs, BerkeleyGW can tackle in just a few nodes computations that previously took thousands of nodes.

The first exascale supercomputer is scheduled to arrive at Argonne National Laboratory in The Carnegie Mellon team is aiming to optimize workflows so their research will be ready to run on the new exascale system.

If the project is successful, it could be used as a template for any kind of machine learning, data-driven discovery of new materials in different fields, setting a standard for what can be used in the future for more applications, says Del Ben.

Powering Scientific Discovery Since Hari Krishnan.In a matter of days, a UC Berkeley science building has converted to a COVID test processing center, with researchers hoping to enable up to thousands more coronavirus tests per day in the East Bay. The Innovative Genomics Institute at Berkeley Way and Oxford Street — founded by Jennifer Doudna, co-developer of gene-editing technology CRISPR — houses robots that will process samples from nearby medical centers and return the results in hours instead of the usual several days, scientists say.

The initiative is launching as reports abound of shortages and delays at every point in the coronavirus testing process across California and the United States. The city of Berkeley does not know how many people in Berkeley have been tested for the virus because, until a recent orderlabs were only required to report positive results.

After UC Berkeley shuttered its labs and the novel coronavirus began spreading throughout the area, many scientists were hoping to apply their expertise to the local mitigation effort. About faculty, graduate students and community members immediately volunteered to help out with the Berkeley effort, according to IGI. The critical items are in short supply these days, so the Berkeley scientists have spent the past week or so seeking out products from non-traditional distributors around the world.

Revised guidelines from federal health authorities and Gov. The initiative was also inspired by similar work being done at the University of Washington, Hamilton said. There is no indication that he got the virus while at work, however, and the lab stressed that cases are likely across all workplaces. Hamilton said there will only be a few people in the IGI lab at a given time, always practicing social distancing. Skip to content. By Natalie Orenstein March 30,6 a. April 3p.

Secretary of Energy Rick Perry. Working with a publicly available dataset MIMIC -III that contains medical record information on about 40, patients from one Boston hospital intensive care unit, they searched for patterns that might point to suicide risk. The real challenge is figuring out a way of tracing how these words are combined internally within the network. This will help provide better insight on common motifs found between suicidal patients.

This image shows a visualization of word embeddings learned by a deep learning model trained for suicide-related admission classification. The graph shows the top words used by the network to classify between written patient discharge summaries.

A subsection of the graph shows words have organized according to common semantic value pertaining to medical conditions. Although the performance of these neural networks is impressive, they are difficult to interpret. Since last summer, the team has continued to work with the MIMIC dataset to fine-tune their understanding of how natural language processing can be used to sift through the structured and unstructured data collected in an EHR, and Liu is heading back to Berkeley Lab this summer with more students to focus again on this project.

According to Crivelli, a few individuals are also about to gain approval to use the MVP dataset — which contains more data than the MIMIC dataset — to further extend this research, especially for suicide risk. They cannot do it alone because they do not have the tools we have at the DOE. Data-driven scientific discovery is poised to deliver breakthroughs across many disciplines, and the DOE, through its national laboratories, is well positioned to play a leadership role.

Deep learning methods represent a promising approach for analytics in science for discovering subtle patterns in very complex scientific data of all kinds, although more work is needed gain to confidence in life-critical applications such as suicide prevention.
