(Phys.org)—Today's photonic and plasmonic devices – the latter based on surface plasmons (a coherent delocalized electron oscillations that exist at the interface between metal and dielectric) and combining the small ...
(Phys.org)—Constructing quantum computers and other quantum devices requires the ability to leverage quantum properties such as superposition and entanglement – but these effects are fragile and therefore hard to maintain. ...
(Phys.org)—The signal-to-noise ratio, or SNR, is a well-known metric typically expressed in decibels and defined as a measure of signal strength relative to background noise – and in statistical terms as the ratio of ...
Metamaterials – engineered materials with properties not found in nature – have led to an astounding range of optical, acoustic, thermodynamic, two-dimensional solid mechanics, and other types of invisibility cloaks that ...
From the perspective of complex systems, a range of events – from chemistry and biology to extreme weather and population ecology – can be viewed as large-scale self-emergent phenomena that occur as a consequence of deteriorating ...
While fluorescence imaging (in which external light is used to excite a specimen that then emits light in response) is essential in cell biology, it has a number of significant drawbacks, including autofluorescence, phototoxicity ...
(Phys.org)—In the complex, somewhat rarified world of interactions between various flavors of RNA, one elusive goal is to understand the precise regulatory relationships between competing endogenous RNA (ceRNA), microRNA ...
(Phys.org)—Although humans are a single species, not all genetic variation is shared between populations – and the ability to sequence our entire genome has allowed scientists to catalogue mutations that occur in one ...
There's more to quantum tunneling than meets the eye – or rather, the visualization technique. (Quantum tunneling is a quantum mechanical phenomenon where a particle transitions through a classically-forbidden energy state.) ...
(Phys.org)—While Einstein considered quantum entanglement as "spooky action at a distance," and those who fully accept entanglement acknowledge it to be counterintuitive, current entanglement-based quantum communication ...
