Dere To Make Updates To CHIANTI Atomic Database & Software

Kenneth Dere, Research Professor, Physics and Astronomy, received funding from NASA for: "Updates to the CHIANTI atomic database and software."

CHIANTI is a database that contains a large quantity of atomic data for the analysis of astrophysical spectra. 

Dere will also conduct maintenance on and make improvements to the ChiantiPy software package. 

ChiantiPy is the Python interface to the CHIANTI atomic database for astrophysical spectroscopy. It allows scientists to calculate the emission line and continuum spectrum of an optically thin plasma based on the data in the CHIANTI database.

Dere received $25,000 from NASA for this project. Funding began in Oct. 2023 and will end in late Sept. 2024.

Want better AI? Get input from a real (human) expert
2023-11-20
RICHLAND, Wash.—Can AI be trusted? The question pops up wherever AI is used or discussed—which, these days, is everywhere.   It’s a question that even some AI systems ask themselves.   Many machine-learning systems create what experts call a “confidence score,” a value that reflects how confident the system is in its decisions. A low score tells the human user that there is some uncertainty about the recommendation; a high score indicates to the human user that the system, at least, is quite sure of its decisions. Savvy humans know to check the confidence score when ...

Boomerang-like beams of light

Boomerang-like beams of light
2023-11-20
Researchers at the University of Warsaw's Faculty of Physics have superposed two light beams twisted in the clockwise direction to create anti-clockwise twists in the dark regions of the resultant superposition. The results of the research have been published in the prestigious journal “Optica”. This discovery has implications for the study of light-matter interactions and represents a step towards the observation of a peculiar phenomenon known as a quantum backflow. “Imagine that you are throwing a tennis ball. The ball starts moving forward with positive momentum. If the ball doesn’t hit an obstacle, you are unlikely to expect it to suddenly ...

Miniature colons with immune components aid the study of intestinal diseases

Miniature colons with immune components aid the study of intestinal diseases
2023-11-20
A team at the Medical University of South Carolina and Cincinnati Children’s has developed a sophisticated model for studying the diseased colon that could lead to the development of personalized treatments for colon-related diseases, such as cancer and inflammatory bowel disease (IBD). The researchers report their findings in the Nov. 2 issue of Cell Stem Cell. MUSC Hollings Cancer Center researcher Jorge Munera, Ph.D., collaborated with James Wells, Ph.D., and Daniel Kechele, Ph.D., both of Cincinnati Children’s, to grow miniature human colons complete with an immune system in the lab. This model improves upon existing organoids, or mini ...

Are vanadium flow batteries worth the hype? (video)
2023-11-20
WASHINGTON, Nov. 20, 2023 — There’s a century-old technology that’s taking the grid-scale battery market by storm. Based on water, virtually fireproof, easy to recycle and cheap at scale, vanadium flow batteries could be the wave of the future. https://www.youtube.com/watch?v=fPtaDqLsbnM Reactions is a video series produced by the American Chemical Society and PBS Digital Studios.

These bats use their penis as an “arm” during sex but not for penetration

These bats use their penis as an “arm” during sex but not for penetration
2023-11-20
Mammals usually mate via penetrative sex, but researchers report November 20 in the journal Current Biology that a species of bat, the serotine bat, (Eptesicus serotinus) mates without penetration. This is the first time non-penetrative sex has been documented in a mammal. The bats’ penises are around seven times longer than their partners’ vaginas and have a “heart-shaped” head that is seven times wider than the vaginal opening. Both the penises’ size and shape would make penetration post-erection impossible, and the researchers show that, rather than functioning as a penetrative ...

AI system self-organizes to develop features of brains of complex organisms

2023-11-20
Cambridge scientists have shown that placing physical constraints on an artificially-intelligent system – in much the same way that the human brain has to develop and operate within physical and biological constraints – allows it to develop features of the brains of complex organisms in order to solve tasks. As neural systems such as the brain organise themselves and make connections, they have to balance competing demands. For example, energy and resources are needed to grow and sustain the network in physical ...

Half of tested caviar products from Europe are illegal, and some aren’t even caviar

Half of tested caviar products from Europe are illegal, and some aren’t even caviar
2023-11-20
Wild caviar, a pricey delicacy made from sturgeon eggs, has been illegal for decades since poaching brought the fish to the brink of extinction. Today, legal, internationally tradeable caviar can only come from farmed sturgeon, and there are strict regulations in place to help protect the species. However, by conducting genetic and isotope analyses on caviar samples from Bulgaria, Romania, Serbia, and Ukraine—nations bordering the remaining wild sturgeon populations—a team of sturgeon experts found evidence that these regulations are actively being broken. Their results, ...

Physicists answer question of Supergalactic Plane’s absent spiral galaxies

Physicists answer question of Supergalactic Plane’s absent spiral galaxies
2023-11-20
Astrophysicists say they have found an answer to why spiral galaxies like our own Milky Way are largely missing from a part of our Local Universe called the Supergalactic Plane. The Supergalactic Plane is an enormous, flattened structure extending nearly a billion light years across in which our own Milky Way galaxy is embedded. While the Plane is teeming with bright elliptical galaxies, bright disk galaxies with spiral arms are conspicuously scarce. Now an international team of researchers, co-led by Durham University, UK, and the University of Helsinki, Finland, say different distributions of elliptical and disk ...

Social determinants of health and cardiologist involvement in the care of adults hospitalized for heart failure

2023-11-20
About The Study: This study of 1,000 participants found that adults with low household income were less likely than adults with higher incomes to have a cardiologist involved in their care during a hospitalization for heart failure. These findings suggest that socioeconomic status may bias the care provided to patients hospitalized for heart failure.  Authors: Parag Goyal, M.D., M.Sc., of Weill Cornell Medicine in New York, is the corresponding author.  To access the embargoed study: Visit our For The Media website at this link https://media.jamanetwork.com/  (doi:10.1001/jamanetworkopen.2023.44070) Editor’s Note: Please see the article ...

Infertility and risk of autism spectrum disorder in children

2023-11-20
About The Study: In this study of 1.3 million children from Ontario, Canada, a slightly higher risk of autism spectrum disorder was observed in children born to individuals with infertility, which appears partly mediated by certain obstetrical and neonatal factors. To optimize child neurodevelopment, strategies should further explore these other factors in individuals with infertility, even among those not receiving fertility treatment.  Authors: Maria P. Velez, M.D., Ph.D., of Queen’s University in Kingston, Ontario, Canada, is the corresponding author.  To access the ...
