INTRO: Every second counts when it comes to detecting and treating heart attacks. That’s where a new technology from the University of Mississippi comes in to identify heart attacks faster and more accurately than traditional methods.
In a study published in Intelligent Systems, Blockchain and Communication Technologies, electrical and computer engineering assistant professor Kasem Khalil shows that a new technology developed at his lab could improve heart attack detection methods without sacrificing accuracy.
“For this issue, a few minutes or even a few extra seconds is going to give this person the care they need before it becomes worse,” Khalil said. “Compared to traditional methods, our technology is up to two times faster, while still highly accurate. Our target was not only to increase performance for classifying heart attacks. We are also focusing on the design. If we want to make this device a usable machine for any person, that means it has to be something lightweight and economic.”
In the United States, someone dies from a heart attack every 40 seconds. Heart disease – a collection of underlying conditions that can lead to a heart attack – is the leading cause of death in the United States. Khalil and his team used artificial intelligence and advanced mathematics to design a chip that can analyze electrocardiograms, known as ECGs – graphs of the heart’s electrical signals – and detect a heart attack in real-time.
The resulting technology is lightweight and energy efficient enough to be embedded in wearable devices while still being 92.4% accurate – higher than many current methods... (MORE - details, no ads)
So, our city’s shrinking—Now what?

PRESS RELEASE: Policymakers often overlook the challenges faced by shrinking small and medium-sized cities. Yet, keeping these cities sustainable is crucial for many urban stakeholders. Unfortunately, the methods that have succeeded in large cities cannot be unilaterally applied to combat this issue. This suggests that a research gap on effective urban management in small and medium-sized cities exists.
Dr. Haruka Kato, a junior associate professor at Osaka Metropolitan University, examined the types of municipal expenditures that correlated with population changes in small and medium-sized cities. The research design used cross-sectional studies from 2007 to 2022 of all small and medium-sized cities in Japan. The nonlinear relationship between data was analyzed using the eXtreme Gradient Boosting algorithm.
The results revealed that 1288 cities were shrinking, accounting for 82.56% of all small and medium-sized cities in Japan. Further, this study identified the types of per capita municipal expenditures that correlated with population change, which were often associated with welfare expenditures. Specifically, the population grew in cities that increased per capita expenditures on children and decreased those on welfare recipients and the older population. Additionally, city planning expenditures were also effective, but only in the maintenance and construction of streets.
“In recent years, urban policymakers have adopted an urban management perspective. With limited financial resources, policymakers must decide what and how much to invest in citizens,” said Dr. Kato. “Our research clearly suggests prioritizing child welfare expenditures as a key strategy to sustain populations in small and medium-sized cities.”
The findings were published in the Journal of Urban Management.
