It is suggested that gravity waves could, in several cases, be detected by means of already (or shortly to be) available technology, independently of current efforts of detection. The present is a follow-up on a recently suggested detection strategy based on gravity-wave-induced deviations of null geodesics. The new development is that a way was found to probe the waves close to the source, whe...

In this paper, a method for measuring 3D cognitive load is proposed. For that, 8-channel EEG data when watching 2D and 3D displays are 2dimensionally reduced using principal component analysis then the reduced features are visualized and compared. Consequently, we confirmed that the difference between two feature distributions of watching 2D and 3D at early stage was significant then the differ...

In contrast to the well-established scientific evidence linking negative emotional states (e.g., depression, anxiety, or anger) to increased risk for cardiovascular disease, much less is known about the association between positive emotional states (e.g., laughter, happiness) and cardiovascular health. We determined the effects of mirthful laughter, elicited by watching comic movies, on endothe...

In the last few years, we have seen a tremendous boost in the efficiency of SAT solvers, this boost being mostly due to Chaff. Chaff owes some of its efficiency to its “two-literal watching” data structure. In this paper we present watched data structures for Quantified Boolean Formula (QBF) satisfiability solvers. In particular, we propose (i) two Chaff-like literal watching schemes for unit c...
