Sign in to download full-size image yield for formation of B is very low (0.001); only 1 in every thousand excited molecules giving product. The rest of the excited molecules decay back to A. If, however, there is no othercompeting process, given enoughtime and light, all A will be ...
Since the stomach gives no obvious external sign of its workings, investigators of gastric movements have hitherto been obliged to confine their studies to pathological subjects or to animals subjected to serious operative interference. Observations made under these necessarily abnormal conditions have ...

that Y and Z imply X?” This is a chance to share observations and improve models. If people disagree over the model, they can devise experiments to test it. If they disagree over the evidence, they can agree on what compelling evidence would look like. In other words, science. ...

The nature of this relaxation of the stress, σ(t), which is driven by the motion and subsequent annihilation of defect pairs of opposite sign, depends on the number of such defects and therefore on the initial strain. If the initial strain (and consequently, the defect density) is small,...
"This sequence of works puts forward a general theory of goal-oriented communication, where the focus is not on the raw data being communicated but rather on its meaning," says Oded Goldreich, a professor of computer science at the Weizmann Institute of Science in Israel. "I consider this se...
