In 2020, stores sold out of garden seed, coops and rabbit cages. Meat shortages led many to wonder what to eat for protein when supply chains are disrupted and some people turned to gathering eggs, raising animals and growing their own food. A team from Michigan Tech and the University of Alaska assessed backyard protein sources: They looked at how a typical household with a typical backyard can raise chickens, rabbits or soybeans to meet its protein needs.
In mathematics, simple equations can generate a complex evolution in time and intriguing patterns in space. One famous example of this is the Mandelbrot set, named after the French-American mathematician of Polish origin, Benoit B. Mandelbrot (1924-2010), the most studied fractal. This set is based on a single quadratic equation with only one parameter and one variable. The fascinating fractal patterns of the Mandelbrot set have attracted attention far beyond mathematics.
Trained to see patterns by analyzing thousands of chest X-rays, a computer program predicted with up to 80 percent accuracy which COVID-19 patients would develop life-threatening complications.
Skoltech scientists have created a new monitoring system for agricultural applications that performs real-time image segmentation on board the drone to identify hogweed. The new approach holds great promise for farming: it could be used to monitor other crops, identify various vegetative indicators, assess plant health, and detect plant detect plant diseases by applying multispectral imagery.
Instead of relying on software to tackle computationally intensive puzzles, researchers at the National Institute of Standards and Technology (NIST) took an unconventional approach. They created a design for an electronic hardware system that directly replicates the architecture of many types of networks.
With the US federal government investing billions of taxpayer dollars in executing technology programs, wouldn't you like to know where this money is going? A new study has identified ways to reduce federal spending in the execution of these taxpayer-funded technology programs.
Researchers report a theoretical way of mimicking thermal objects or making objects invisible to thermal measurements. And it doesn't require a Romulan cloaking device or Harry Potter's invisibility cloak.
Network scientists from Beijing Normal University and Bar-Ilan University address the effect of team freshness on the originality and multidisciplinary impact of produced work, by systematically investigating prior collaboration relations between team members. Among other things their study, published in Nature Human Behaviour, reveals that papers of fresher teams are significantly more effective than those of older teams in creating studies of higher originality and greater multidisciplinary impact.
St. Petersburg, like other cities in the Russian Federation, is actively participating in the establishment of the "Smart City" program, which will provide new services for residents of the megalopolis, increasing the safety of citizens. Digital services are essential for such a system. Due to the Internet of Things (IoT) systems, the environment can adapt to the needs of humanity on its own accord. Cybersecurity threats are especially dangerous for such infrastructure.
While video games can be engaging, some have a higher potential of becoming addictive. However, the mechanisms underlying this addiction are difficult to analyze mathematically. Now, researchers from JAIST, Japan apply the concept of "motion in the mind" to investigate the subjective aspects of different games via analogies with physical models of motion. Their findings explain what makes certain videogames more addictive by nature and will help us tailor games better for specific purposes.
