Of noise and neurons: Sensory coding, representation and short-term memory

(Phys.org)—While much is known about the limiting effect of neural noise on the fidelity of sensory coding representation, knowledge about the impact of noise in short-term memory and integrator networks has remained more ...

Physicists observe novel quantum effect that limits the number of emitted photons

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called Poisson-distribution. There are, however, light sources with non-classical ...

Model of galaxy and star cluster formation corrected

When galaxy clusters and globular star clusters form, a phenomenon called "violent relaxation" occurs. After interacting intensely, the thousands or even millions of bodies reach a state of relative gravitational equilibrium ...

Why we've got the cosmological constant all wrong

(PhysOrg.com) -- Some scientists call the cosmological constant the "worst prediction of physics." And when today’s theories give an estimated value that is about 120 orders of magnitude larger than the measured value, ...

Effects of porosity on piezoelectric characteristics of polyvinylidene fluoride films for biomedical applications

Polyvinylidene fluoride (PVDF) is a piezoelectric polymer material that has shown great aptitude as a pressure and flow sensor, especially in biomedical applications. However, most of the PVDF thin film sensors have low sensitivity ...
