In 26 normal volunteers, increase in heart rate from mean 73-94 +/- 1-97 to 103-61 +/- 2-72/min, by either intravenous atropine administration or rapid right atrial pacing, produced definite changes in the uncorrected systolic time intervals. As expected, total electromechanical systole (QS2) and left ventricular ejection time (LVET) were shortened, while the pre-ejection period (PEP) was unaff...

A proof of the soundness of Tofte's imperative type discipline with respect to a structured operational semantics is given. The presentation is based on a semantic formalism that combines the bene ts of the approaches considered by Wright and Felleisen, and by Tofte, leading to a particularly simple proof of soundness of Tofte's type discipline. This research was sponsored by the Defense Advanc...

We present a method to produce stable proton and helium ion beams with energies of 10–100 keV from a 30-year-old Van De Graaff accelerator using an external stabilized DC voltage supply instead of the belt charging system. Requiring no other modif...

After a long period of waiting in ambush on the hub its orb web, an araneid spider (Cyclosa argenteoalba) was found to stretch out body and legs, exhibiting distinctive behavior known as pandiculation (https://bit.ly/2TUp5SY). This coordinated movement is clearly different from that excretion (https://bit.ly/3fzwcYR). Pandiculation natural instinctive activity, often accompanying yawning, perfo...

We report measurements of the energy dependence of the total neutron scattering cross-section of CH4 both in bulk and confined in aerogel glass for neutron energies between 0:3 and 200 meV. Solid CH4 in phase II is an effective slow neutron moderat...
