Abstract: The fundamental limits of antennas tie its electrical size to its quality factor (Q-factor) and radiation efficiency. The Q-factor is linearly proportional to the inverse of the ...

A forgotten cup of coffee will gradually cool down as its heat flows into the cooler surrounding air, but in the quantum realm, it appears this experience can be turned on its head. As a result, we ...

Unexpected credit limit reductions can significantly impact your credit utilization ratio, potentially harming your credit score even if you've never missed a payment. Common reasons for credit limit ...

A lowered credit limit isn’t always personal since issuers often cut limits as part of broader changes. The major issue could involve your credit utilization ratio, which jumps overnight since ...

President Trump said his “own morality” guides his decisions on foreign intervention in an interview published Thursday, following weeks of scrutiny for U.S. strikes overseas. “Yeah, there is one ...

The Trump administration is soon expected to propose a plan that would cap loans for a number of advanced degrees—including master’s and doctoral degrees in nursing—and it’s gone viral on social media ...

The physics of thermodynamics, which involves quantities like heat and entropy, offers well-established tools for determining how far from equilibrium an idealised system of particles is. But when it ...

What if the future of artificial intelligence wasn’t just faster or smarter, but fundamentally more sustainable? Picture this: a world where the energy demands of AI no longer threaten to outpace our ...

After a century of observations spanning the breadth of the cosmos and theoretical insights that push humanity's vision of the universe to its utmost limits, we can finally, confidently say that the ...

(Nanowerk News) Harnessing quantum states that avoid thermalization enables energy harvesters to surpass traditional thermodynamic limits such as Carnot efficiency, report researchers from Japan. The ...

This infographic depicts a simplified diagram of the novel energy-harvesting technique using the TL liquid. Implementation of this strategy in practice could help in the conversion of waste heat ...

A study published in Physical Review Letters (PRL) details a "Gambling Carnot Engine" that researchers report can attain 100% efficiency while also improving power generation. The researchers present ...
