What The Study Did: Researchers found that DNA detection of human papillomavirus (HPV) genotypes 16/18 infection in the first and third trimesters of pregnancy was associated with an increased risk of preterm birth.

One of the frequently used methods to monitor endangered whales is called passive acoustics technology, which doesn’t always perform well. In the increasingly noisy ocean, current methods can mistake other sounds for whale calls. This high “false positive” rate hampers scientific research and hinders conservation efforts. Researchers used artificial intelligence and machine learning methods to develop a new and much more accurate method of detecting Right whale up-calls – a short “whoop” sound that lasts about two seconds.

Exterior calculus is a branch of differential geometry in Mathematics that studies geometry of smooth shapes and spaces respectively using the techniques of differential Calculus, integral calculus, linear and multi linear algebra and with exterior algebra. The field has its origins in the study of spherical geometry as far back as antiquity. In Exterior calculus the concept of differentiations is generalized to asymmetric exterior derivatives and the notions of ordinary integration to differential forms of higher degree of arbitrary dimensions. It therefore generalizes the fundamental theorem of calculus to Stokes' theorem that links the concept of differentiating a function with the concept of integrating a function.
Unique in its direct and comprehensive approach, the aim of Trefftz and Fundamental Solution-Based Finite Element Methods is to fill the gap mentioned above and present fundamental knowledge of boundary type FEM and comprehensive treatment of its algorithms. The volume summarizes the current state of practice and presents the most recent research outcomes in the subject. It details the development of each of the ideas and techniques beginning with fundamental principles, and new concepts are illustrated with simple examples wherever possible.
AI introduces new approaches to solve complex problems. It is interesting to note that AI introduces a significant shift in new models and algorithms. Advances in instrument technologies have seen a significant change as far as the tools and techniques are concerned. Subsequently, it has made and is going to make equally powerful influence on the process and manufacturing industry through Industry 4.0.
Researchers have developed a real-time approach that can help prevent incidents like the large-scale disruption at London’s Gatwick Airport in 2018, where possible drone sightings at the perimeter of the airport caused the cancellation of hundreds of flights.
