When designing flying vehicles, there are many aspects of which we can be certain but there are also many uncertainties. Most are random, and others are just not well understood. University of Illinois Professor Harry Hilton brought together several mathematical and physical theories to help look at problems in more unified ways and solve physical engineering problems.
Like fingerprints, no 3D printer is exactly the same. That's the takeaway from a new University at Buffalo-led study that describes what's believed to be the first accurate method for tracing a 3D-printed object to the machine it came from. The advancement could help law enforcement and intelligence agencies track the origin of 3D-printed guns, counterfeit products and other goods.
MIT researchers have developed a cryptographic system that could help neural networks identify promising drug candidates in massive pharmacological datasets, while keeping the data private. Secure computation done at such a massive scale could enable broad pooling of sensitive pharmacological data for predictive drug discovery.
Quantum computers promise to revolutionize the future of computing. A scientist from the Technical University of Munich (TUM) together with his colleagues from the University of Waterloo and from IBM have now demonstrated for the first time that quantum computers do indeed offer advantages over conventional computers. They developed a quantum circuit that can solve a problem that is unsolvable using any equivalent classical circuit.
The fall of Angkor has long puzzled historians, archaeologists and scientists, but now a University of Sydney research team is one step closer to discovering what led to the city's demise -- and it comes with a warning for modern urban communities.
The architecture of each person's brain is unique, and differences may influence how quickly people can complete various cognitive tasks. But how neuroanatomy impacts performance is largely an open question. To learn more, scientists are developing a new tool -- computational models of the brain -- to simulate how the structure of the brain may impact brain activity and, ultimately, human behavior.
Sydney may soon undergo a transition from a monocentric city with sprawling suburbs radiating from one CBD, to a polycentric model -- one marked by several sub-centres -- according to a recent study led by a multidisciplinary team at the University of Sydney. Topics: Greater Sydney Commission, urbanisation, urban sprawl, complex systems, transport, residential, suburbs
Researchers from MIT and Massachusetts General Hospital have developed an automated model that assesses dense breast tissue in mammograms -- which is an independent risk factor for breast cancer -- as reliably as expert radiologists. This marks the first time a deep-learning model of its kind has successfully been used in a clinic on real patients, according to the researchers. With broad implementation, the researchers hope the model can help bring greater reliability to breast density assessments across the nation.
A RUDN physicist demonstrated how to describe the shape of any symmetrical wormhole -- a black hole that theoretically can be a kind of a portal between any two points in space and time -- based on its wave spectrum. The research would help understand the physics of wormholes and better identify their physical characteristics. The article of the scientist was published in the Physics Letters B journal.
Doctors use invasive procedures to decide whether an ablation procedure to remove heart tissue is likely to have a positive outcome. CT scans or ultrasounds are useful in determining the structure of a patient's heart, but invasive electrical procedures are used to identify and localize the source of the atrial fibrillation. Researchers have developed new algorithms to localize the source of an atrial fibrillation. They report their findings in APL Bioengineering.
