For centuries people have placed the highest value on diamonds that are not only large but flawless.
Phases are integral to how we define our world. We navigate through the phases of our lives, from child to teenager to adult, chaperoned along the way by our changing traits and behaviors. Nature, too, undergoes phase changes. Lakes can freeze for the winter, thaw in the spring and lose water to evaporation in the dog days of summer. It's useful to capture and study the differences that accompany these dramatic shifts.
For humans, background noise is generally just a minor irritant. But for quantum computers, which are very sensitive, it can be a death knell for computations. And because "noise" for a quantum computer increases as the computer is tasked with more complex calculations, it can quickly become a major obstacle.
Although tropical forest ecosystems around the world have been modified and fragmented by agroforests planted to produce commodities such as coffee, rubber and areca palm, amphibian communities can survive in those transformed landscapes—if the agroforests are managed to support biodiversity.
In recent times, sustainable development has been the overarching guiding principle of research concerning environmental issues, energy crises, and information and communication technology. In this regard, spintronic devices have emerged as promising candidates for surpassing conventional technology, which has run into the problem of excess waste heat generation in miniaturized devices. The electron "spin" responsible for the electric and magnetic property of a material are being used to develop next generation energy-efficient and miniature spintronic devices. At the heart of this new technology are "magnons," quanta of spin excitation waves, and their detection is key to further progress in this field. Recently, within the field of spintronics, devices based on the interaction between spin and heat flow have emerged as a potential candidate for new thermoelectric devices (devices which convert heat to electricity).
In spring 2018, Dr. Philip Matthews spent a typical afternoon capturing dragonflies in the University of British Columbia's (UBC) experimental ponds. Little did the zoologist know he was about to embark on a journey to solve a century-old entomological mystery involving a much smaller but equally intriguing insect. As he worked in the ponds, larvae floating in rainwater in a nearby cattle tank caught his eye.
