Acosta & Burls using weather model & geologic data to test tectonic mechanisms in intercontinental setting
2023-08-21
(Press-News.org)
Paul Acosta, Postdoctoral Scholar, Atmospheric, Oceanic and Earth Sciences (AOES), and Natalie Burls, Associate Professor, AOES; Graduate Program Director, Climate Dynamics, received funding from the National Science Foundation for the project: "Collaborative Research: Using a weather model and geologic data to test tectonic mechanisms in an intercontinental setting: The Altai Mountains of Central Asia."
This project seeks to apply new advances in atmospheric and geosciences to a natural experiment in central Asia where the height and shape of the Altai Mountains over the past 50 million years are thought to have precipitated a major change in atmospheric circulation and in climate. The Altai Mountains are one of the major ranges in Asia that substantially modify regional climate and ecosystems and spawn some of the largest intracontinental earthquakes ever recorded.
This research will use novel weather and climate models to predict changes in atmospheric circulation and climate in response to the size, height, and growth history of the Altai. These model predictions will be measured against field and laboratory data gleaned from the sediments shed from the Altai. Using rock magnetic data preserved in the sediments and the steepness of river channels carved into the mountains, the investigators will be able to construct an age model consistent with the onset and growth history of the Altai range.
This interdisciplinary approach will be pursued by a multi-university, diverse team in the United States that includes early-career scientists and professors, graduate students, and undergraduates in collaboration with Mongolian colleagues at the Institute for Astronomy and Geophysics. The project will train three doctoral students, three early-career scientists, and one undergraduate in interdisciplinary geosciences and build international exchange opportunities.
The results of this research will improve understanding of the coupling among solid Earth and atmospheric processes. The importance of this research helps address societal challenges, such as building resistance to climate change and earthquake-related natural hazards.
Acosta and Burls received $34,998 from NSF for this project. Funding began in Aug. 2023 and will end in late July 2026.

Jinwei Ye, Assistant Professor, Computer Science, received funding for the project: "CAREER: Towards Polarimetric Visual Understanding."
In this project, Ye will study how the way surfaces reflect polarized light can be used to help recognize objects more effectively.
Ye will address the following two questions: (1) How does the polarization of light change after interacting with various types of surfaces? (2) What can polarized light tell us about the kinds of objects that it has interacted with?
Addressing these questions can lead to significant improvements in machine vision systems by strengthening their capability to do geometric ...

One of the hallmarks of Alzheimer’s disease is disruption to the body’s circadian rhythm, the internal biological clock that regulates many of our physiological processes. Nearly 80% of people with Alzheimer’s experience these issues, including difficulty sleeping and worsening cognitive function at night. However, there are no existing treatments for Alzheimer’s that target this aspect of the disease.

How does a gambler maximize winnings from a row of slot machines? This is the inspiration for the "multi-armed bandit problem," a common task in reinforcement learning in which "agents" make choices to earn rewards. Recently, an international research team led by Hiroaki Shinkawa at the University of Tokyo developed an extended photonic reinforcement learning scheme that moves from the static bandit problem towards a more challenging dynamic environment. This study was published July 25 in Intelligent Computing, a Science Partner Journal.

August 21, 2022 – Implantable penile prostheses (IPPs) are an established treatment option for erectile dysfunction (ED), and are covered by insurance in about 80% of cases, reports a paper in the September issue of Urology Practice®, an Official Journal of the American Urological Association (AUA). The journal is published in the Lippincott portfolio by Wolters Kluwer.
However, some employer-sponsored insurance plans specifically exclude this guideline-recommended treatment option for ED, according to the new research by Dr. Mohit Khera, MD, MBA, MPH, of Baylor College ...

Neuroscientists at Radboudumc show that adversities permanently change the functioning of the brain. Furthermore, an aberrant reaction of the brain to adversities is related to anxiety symptoms. This may have predictive value for the development of psychiatric disorders.
Your brain is shaped by the things you experience. That sounds logical, but can you really measure that? And what can you do with it? Neuroscientists at Radboud university medical center investigated the influence of adversities in life on patterns in the brain. They found remarkable associations that may have predictive value for the development of psychiatric disorders.

Alcohol consumption is a significant risk factor for gastrointestinal diseases, including cancer. Alcohol can damage the gastrointestinal tract in several ways. It can promote an impairment of several intestinal barrier functions, leading to leaky gut and dysbiosis. Ethanol metabolism can also produce toxic substances such as acetaldehyde and acetate, further damaging the gut and potentially promoting cancer. Ethanol and its metabolites enhance DNA damage response and dysregulate the epithelial proliferation/differentiation program, thereby increasing the risk of cancer development.
In a new paper published in eGastroenterology, ...

#FRANKFURT. Immediately after the infection of a cell in the throat or lungs, the SARS-CoV-2 virus works very hard to replicate, using the human cell’s metabolic pathways to produce its proteins and make sure that its genetic material (the RNA genome) is copied. The RNA genome is then packaged very compactly into new virus particles that are released from the cell to infect more cells.
One viral protein, called the nucleocapsid protein (N), is particularly important for rapid and efficient replication. ...

Applying ground-up silicate rock to Midwestern farm fields can capture significant amounts of carbon dioxide and prevent it from accumulating in the atmosphere, according to a new study that successfully quantified those climate benefits for the first time.
Working with Eion Corp., researchers at the University of Illinois Urbana-Champaign and the Leverhulme Centre for Climate Change Mitigation (LC3M) developed a new method to calculate the CO2-reduction potential of basalt rock amendments applied to cropland soil, a process known as enhanced weathering.
Traditional row-crop agriculture releases sizable amounts of soil-derived carbon to the atmosphere as CO2, a greenhouse gas ...
