Kyklos, EarlyView.ABSTRACT This article proposes that wars are fought to bring about and monitor mutual reductions of overinvestment in broadly defined military preparedness. If two potential combatants are overinvested in military preparedness, it is in their individual interest to scale down in order to use their resources in politically more desirable ways.

How to make people do things with words
Noûs, EarlyView.Abstract Sometimes we do what other people tell us to. A natural thought is that the motivation to act on an instruction comes about rationally as the result of interpreting an imperative and deciding to act on it; that is, by updating on information that gets mediated through belief‐desire reasoning.

Civil tiltrotor missions and applications. Phase 2: The commercial passenger market [PDF]
The commercial passenger market for the civil tiltrotor was examined in phase 2. A market responsive commercial tiltrotor was found to be technically feasible, and a significant worldwide market potential was found to exist for such an aircraft ...

Experimental Physiology, EarlyView.Abstract Manned space exploration to distant destinations, including Mars, continues to be an aspiration of humankind. Space travel does, however, present many challenges to the body, amongst which adaptation to microgravity is perhaps the largest. For instance, both short and long manned spaceflight missions have shown substantial deleterious effects ...

Impact ejecta on the moon [PDF]
The partitioning of energy and the distribution of the resultant ejecta on the moon is numerically modeled using a Eulerian finite difference grid. The impact of an iron meteoroid at 15 km/sec on a gabbroic anorthosite lunar crust is examined.

Experimental Physiology, EarlyView.Abstract figure There is positive covariation in the amplitudes of motor evoked potentials (MEPs) generated by (near simultaneous) stimulation of the two motor cortices. That is, larger responses to stimulation of the left motor cortex tend to be accompanied by larger responses to stimulation of the right motor cortex, and smaller responses to ...

Liquid oxygen-compatible filament-winding matrix resin [PDF]
Polyurethanes derived from hydroxy terminated polyperfluoro propylene oxide prepolymers were evaluated as matrix resins for filament wound composites which would be exposed to liquid (and 100% gaseous) oxygen environments.
