Research scientists in Switzerland have developed and tested a robust AI model that automatically segments major anatomic structures in MRI images, independent of sequence. In the study, the model outperformed other publicly available tools.
Using mathematical modeling, researchers have discovered that rate-induced tipping, which can happen if an environment changes too fast, can happen even in Daisyworld, a simple daisy-filled ecological model. If the planet heats up or cools down too quickly, all the daisies will go extinct, even if they would otherwise have been able to survive just fine under those conditions. This discovery mirrors similar observations found in other models and observed in real-life ecosystems.
An international collaboration sheds new light on the relationship between quantum theory and thermodynamics. The research group demonstrated that while the laws of quantum theory alone do not inherently prevent violations of the second law of thermodynamics, any quantum process can be implemented without actually violating the law. This surprising result suggests a peaceful coexistence between quantum theory and thermodynamics, despite their logical independence. This discovery could have profound implications for understanding the thermodynamic limits of quantum technologies, such as quantum computing and nanoscale engines.
A study by economists shows a wide gap between the kinds of math problems kids who work in retail markets do well and the kinds of problems kids in school do well.
By analyzing almost 10,000 pregnancies, researchers discovered previously unidentified combinations of risk factors linked to serious negative pregnancy outcomes, finding that there may be up to a tenfold difference in risk for infants who are currently treated identically under clinical guidelines.
Can a computer learn a language the way a child does? A recent study sheds new light on this question. The researchers advocate for a fundamental revision of how artificial intelligence acquires and processes language.
Researchers propose a novel system that uses standing surface acoustic waves to separate circulating tumor cells from red blood cells with unprecedented precision and efficiency. The platform integrates advanced computational modeling, experimental analysis, and artificial intelligence algorithms to analyze complex acoustofluidic phenomena. The researchers included an innovative use of dualized pressure acoustic fields and strategically located them at critical channel geometry positions on a lithium niobate substrate. By means of acoustic pressure applied within the microchannel, the system design provides for the generation of reliable datasets.
Our bodies are made up of around 75 billion cells. But what function does each individual cell perform and how greatly do a healthy person's cells differ from those of someone with a disease? To draw conclusions, enormous quantities of data must be analyzed and interpreted. For this purpose, machine learning methods are applied. Researchers have now tested self-supervised learning as a promising approach for testing 20 million cells or more.
Researchers applied the mathematical theory of synchronization to clarify how recurrent neural networks (RNNs) generate predictions, revealing a certain map, based on the generalized synchronization, that yields correct target values. They showed that conventional reservoir computing (RC), a type of RNN, can be viewed as a linear approximation, and introduced a 'generalized readout' incorporating further order approximations. Using a chaotic time-series forecasting task, they demonstrated that this approach dramatically enhances both prediction accuracy and robustness.
The process of updating deep learning/AI models when they face new tasks or must accommodate changes in data can have significant costs in terms of computational resources and energy consumption. Researchers have developed a novel method that predicts those costs, allowing users to make informed decisions about when to update AI models to improve AI sustainability.
