In an article in Brain, researchers at the Medical University of South Carolina (MUSC) and elsewhere report which brain regions must be intact in stroke survivors with aphasia if they are to perform well in a speech entrainment session, successfully following along with another speaker.One of the main causes of aphasia is stroke, the third leading cause of death in the U.S. About one in three stroke survivors develops aphasia.Patients with non-fluent aphasia speak in short, halting, telegraphic sentences and have trouble forming their words."Speech entrainment is asking the person to repeat in real time what they hear and see, or in other words to copy the speech of another speaker," said Leonardo Bonilha, M.D., Ph.D., who led the study.Bonilha is the SmartState Endowed Chair for Brain Imaging and an associate professor in the Department of Neurology at MUSC.Other team members include C-STAR collaborators from Johns Hopkins University and the University of California, Irvine.
If solving a Rubik's Cube wasn't hard enough already, you can now test your skills against the dextrous new artificial intelligence system created by OpenAI.In an 18-second video posted to the company's Twitter account Tuesday, OpenAI's new robot masters the cube quickly with a single, human-like robotic hand."This is an unprecedented level of dexterity for a robot, and is hard even for humans to do," OpenAI tweeted.Earlier this year, researchers at the University of California at Irvine unveiled an AI algorithm (sans robot arm) that can analyze more than 10 billion possible combinations to solve a Rubik's cube in just over a second.OpenAI's robot still hasn't perfected its technique, though.It only solves the cube 60% of the time, according to the company's blog.

Irvine, Calif. - Researchers at the University of California, Irvine have developed a new scanning transmission electron microscopy method that enables visualization of the electric charge density of materials at sub-angstrom resolution.With this technique, the UCI scientists were able to observe electron distribution between atoms and molecules and uncover clues to the origins of ferroelectricity, the capacity of certain crystals to possess spontaneous electric polarization that can be switched by the application of an electric field."This method is an advancement in electron microscopy - from detecting atoms to imaging electrons - that could help us engineer new materials with desired properties and functionalities for devices used in data storage, energy conversion and quantum computing," said team leader Xiaoqing Pan, UCI's Henry Samueli Endowed Chair in Engineering and a professor of both materials science & engineering and physics & astronomy.Employing a new aberration-corrected scanning transmission electron microscope with a fine electron probe measuring half an angstrom and a fast-direct electron detection camera, his group was able to acquire a 2D raster image of diffraction patterns from a region of interest in the sample."With our new microscope, we can routinely form an electron probe as small as 0.6 angstrom, and our high-speed camera with angular resolution can acquire 4D STEM images with 512 x 512 pixels at greater than 300 frames per second," Pan said."Using this technique, we can see the electron charge distribution between atoms in two different perovskite oxides, non-polar strontium titanate and ferroelectric bismuth ferrite."
Irvine, Calif., Sept. 17, 2019 - An interdisciplinary team of scientists at the University of California, Irvine has developed a new technique for predicting the final size of a wildfire from the moment of ignition.Built around a machine learning algorithm, the model can help in forecasting whether a blaze is going to be small, medium or large by the time it has run its course - knowledge useful to those in charge of allocating scarce firefighting resources."A useful analogy is to consider what makes something go viral in social media," said lead author Shane Coffield, a UCI doctoral student in Earth system science."We can think about what properties of a specific tweet or post might make it blow up and become really popular - and how you might predict that at the moment it's posted or right before it's posted."It sounds extreme, but this scenario has become all too common in recent years in parts of the western United States as climate change has resulted in hot and dry conditions on the ground that can put a region at high risk of ignition.By feeding it climate data and crucial details about atmospheric conditions and the types of vegetation present around the starting point of a fire, the researchers could predict the final size of a blaze 50 percent of the time.
In the last decade, many commentators have expressed concern over how much time we spend using technology and its effects on mental health.This is particularly an issue with younger people, who can experience high rates of cyberbullying and can have adverse reactions to social media.However, teens themselves don’t necessarily agree, with surveys showing they are aware of the potential downsides of using technology but are also positive about its benefits.A new study from the University of California, Irvine, investigated this issue by tracking how much time teens spent on their phones and seeing if this was linked to worse mental health outcomes.And spoiler alert: The researchers didn’t find a link between technology use and mental health.The team surveyed over 2000 young people and then specifically tracked the smartphone use of nearly 400 subjects between the ages of 10 and 15 for two weeks.
Voters may form false memories after seeing fabricated news stories, especially if those stories align with their political beliefs, according to research in Psychological Science, a journal of the Association for Psychological Science.The research was conducted in the week preceding the 2018 referendum on legalizing abortion in Ireland, but the researchers suggest that fake news is likely to have similar effects in other political contexts, including the U.S. presidential race in 2020."In highly emotional, partisan political contests, such as the 2020 US Presidential election, voters may 'remember' entirely fabricated news stories," says lead author Gillian Murphy of University College Cork."In particular, they are likely to 'remember' scandals that reflect poorly on the opposing candidate.'She and her colleagues, including leading memory researcher Elizabeth Loftus of the University of California, Irvine, recruited 3,140 eligible voters online and asked them whether and how they planned to vote in the referendum.The researchers then informed the eligible voters that some of the stories they read had been fabricated, and invited the participants to identify any of the reports they believed to be fake.
A team of scientists recently conducted a first-of-its-kind experiment to study the effects of space radiation on a living brain.And the results don’t bode well for NASA‘s planned mission to Mars.The research was conducted by lead author Charles Limoli and scientists from University of California, Irvine, Stanford University, Colorado State University, and the Eastern Virginia School of Medicine.It involved using a new neutron irradiation facility to expose laboratory mice to the same levels of radiation they’d experience in space.According to the team’s paper:We have uncovered that realistic, low dose rate exposures produce serious neurocognitive complications associated with impaired neurotransmission.
An artificial intelligence algorithm is putting humans to shame by solving a Rubik's Cube in just over a second.The algorithm, called DeepCubeA, was created by researchers at University of California, Irvine.The results are described in a study published Monday in Nature Machine Intelligence.The algorithm was presented with 10 billion combinations for the cube.The goal was to decode them all in 30 moves, which exceeds or is equal to human performance.DeepCubeA was then tested on 1,000 combinations and solved them all, doing so in the least number of moves around 60% of the time.
"It's a venture capital-backed mindset where you want to have many product iterations fail as quickly as you can," says Sean Dettrick, the company's director of computational sciences."If you have a bad concept you want to realize that as quickly as possible and move on to the next concept."The Department of Energy (DOE) has fueled TAE Technologies' quest in with awards of computer time through the INCITE (Innovative and Novel Computational Impact on Theory and Experiment) program.Theta helps TAE sift the physical models underlying codes that simulate the vastly different temporal and spatial scales inherent to plasma physics.The company's ambitious goal is to generate affordable, abundant, carbon-free energy for everyone with no environmental impact, no harmful byproducts, and no meltdown risk."We have a program to create a completely simulated FRC in a computer," says Toshiki Tajima, the Norman Rostoker Chair Professor of Physics and Astronomy at the University of California, Irvine, and TAE's chief science officer.
Irvine, Calif., July 16, 2019 - A new wireless transceiver invented by electrical engineers at the University of California, Irvine boosts radio frequencies into 100-gigahertz territory, quadruple the speed of the upcoming 5G, or fifth-generation, wireless communications standard.The team's innovation is outlined in a paper published recently in the IEEE Journal of Solid-State Circuits."The Federal Communications Commission recently opened up new frequency bands above 100 gigahertz," said lead author and postgraduate researcher Hossein Mohammadnezhad, a UCI grad student at the time of the work who this year earned a Ph.D. in electrical engineering & computer science.Having transmitters and receivers that can handle such high-frequency data communications is going to be vital in ushering in a new wireless era dominated by the "internet of things," autonomous vehicles, and vastly expanded broadband for streaming of high-definition video content and more.According to Heydari, changing frequencies of signals through modulation and demodulation in transceivers has traditionally been done via digital processing, but integrated circuit engineers have in recent years begun to see the physical limitations of this method."Moore's law says we should be able to increase the speed of transistors - such as those you would find in transmitters and receivers - by decreasing their size, but that's not the case anymore," he said.
Even so, human nerds are left in the dust and this neural net can be used for other tricksA new neural-network can solve a Rubik’s cube twice as fast as the fastest human – though roughly three times slower than the fastest dumb algorithm – according to research published in Nature Machine Intelligence on Monday.Though the AI approach is not a nippy as the fastest traditional computational method, specifically the world-beating min2phase algorithm out of MIT, it has promise beyond old-school playground puzzles: for one thing, it could be put to better use studying proteins.People who enter these contests are known as speedcubers, and the current world record belongs to Yusheng Du, a Chinese speedcuber that cracked the puzzle in just 3.47 seconds.The system developed by a team of researchers at the University of California, Irvine (UCI), made up of a deep neural network can solve a Rubik’s Cube in an average of 28 moves in 1.2 seconds, Forest Agostinelli, first author of the paper and a PhD student at UCI, told The Register.DeepCubeA was trained using reinforcement learning.
