Spaced-out electrons.
expect photons, the quanta of sunlight, to arrive at Earth at random intervals, their arrival times distributed in just the same, natural way that customers arrive at a box-office to buy tickets for a play. A histogram of the number of people or photons arriving per unit time follows what is known as the Poisson distribution. But in 1909, in the first clear evidence for wave–particle duality, E...

متن کاملSpaced just right
Trimming ERAD U biquitins are zip codes for proteins heading to the proteasome. But misfolded ER proteins must be deubiquitinated before they are degraded, as shown by Wang et al. on page 963. Misfolded ER proteins are sent back through the ER membrane into the cytosol by the p97 ATPase. Upon reaching the membrane’s cytosolic side, the substrates are modifi ed by ubiquitin ligases. Wang et al. ...
متن کاملFractionally Spaced Bayesian Equalizer
In digital communication system, conventional fractionally spaced equalizer (FSE) is based on linear transversal equalizer (LTE) where the noise enhancement influences the equalization result. Since equalization can also be viewed as a classification problem, the Bayesian equalizer which is the optimal symbol-decision equalizer can achieve better performance than LTE. A novel fractionally space...
متن کاملClosely spaced saccades.
The relationships between saccadic velocity, duration, and magnitude have been used to prove the normalcy of saccades with intersaccadic intervals of less than 200 ms. Pairs of normal saccades with small intersaccadic intervals will have the second saccade larger or smaller and going in the same or the opposite direction than the first saccade. These normal saccades may be horizontal, vertical,...
