Abstract: In complex-valued neural network (CVNN) applications, complex number calculations require high performance rather than high precision. However, most previous studies focused on ...

Last spring, 555 students enrolled in CHEM 0350: “Organic Chemistry I.” But during pre-registration this fall, prospective students were met with a new course cap: Only 410 students were able to ...

Psychology is a fascinating subject, but it can be difficult to understand concepts. Most of the students have difficulties in applying theory from the textbook to real instances; hence, the subject ...

The molecules are building blocks of the chemical precursors of things such as RNA. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Frozen ...

A century ago, the strange behavior of atoms and elementary particles led physicists to formulate a new theory of nature. That theory, quantum mechanics, found immediate success, proving its worth ...

STOCKHOLM — Three scientists won the Nobel Prize in chemistry on Wednesday for their development of metal–organic frameworks that could eventually help reduce pollution and combat climate change. A ...

Organic synthesis has advanced remarkably in its ability to construct pharmaceutical ingredients, natural products, agrochemicals, ligand architectures, and functional building blocks for materials ...

The prize was awarded to Susumu Kitagawa, Richard Robson and Omar Yaghi for the development of an architecture that some chemists compare with a molecular sponge. By Alexa Robles-Gil and Ali Watkins ...

Rachel Feltman: Happy Monday, listeners! For Scientific American’s Science Quickly, I’m Rachel Feltman. Let’s kick off the week with a quick roundup of some science news you may have missed. First, ...

Enceladus, a 500-kilometer-wide moon of Saturn, has been a top target in the hunt for extraterrestrial life for nearly two decades. In 2005, shortly after arriving in orbit around the ringed planet, ...

Scientists digging through data collected by the Cassini spacecraft have found new complex organic molecules spewing from Saturn's moon Enceladus. This is a clear sign that complex chemical reactions ...
