We present the results of searches for nucleon decay via n → ¯ νπ 0 and p → ¯ νπ þ using data from a combined 172.8 kt · yr exposure of Super-Kamiokande-I,-II, and-III. We set lower limits on the partial lifetime for each of these modes: τ n→¯ νπ 0 > 1.1 × 10 33 years and τ p→¯ νπ þ > 3.9 × 10 32 years at a 90% confidence level.
[1] The Chemical Weather Forecast System (CFORS) is designed to aid in the design of field experiments and in the interpretation/postanalysis of observed data. The system integrates a regional chemical transport model with a multitracer, online system built within the Regional Atmospheric Modeling System (RAMS) mesoscale model. CFORS was deployed in(More)
The results of the second phase of the Super-Kamiokande solar neutrino measurement are presented and compared to the first phase. The solar neutrino flux spectrum and time-variation as 2 well as oscillation results are statistically consistent with the first phase and do not show spectral distortion. The time-dependent flux measurement of the combined first(More)
We describe a newly developed three-dimensional optometer III (TDO III) that can measure simultaneously three major ocular functions-accommodation, eye movement, and pupil diameter-and head movement in an actual working environment. The TDO III permits free head movement as well as free eye movement because the measurement component is mounted on the head.(More)
The three-dimensional optometer (TDO III) was used to measure accommodative responses when gazing at a spotlight that changed its diameter in an otherwise completely dark room. Three emmetropic females served as subjects and the stimuli were presented at 33 cm (-3 D) from the subjects. The subjects felt that the spotlight approached them when its diameter(More)
A three-dimensional optometer (TDO), which can measure simultaneously three major ocular functions in a working environment, was used to measure the visual responses of human subjects viewing: (1) actual artworks and (2) corrugation presented by moving random dots on a cathode ray tube (CRT). Measurements were performed in natural viewing conditions on two(More)
A (p, q) graph G is called edge-magic if there exists a bijective function f : V (G) ∪ E(G) → {1, 2,. .. , p + q} such that f (u) + f (v) + f (uv) is constant for any edge uv of G. Moreover, G is said to be super edge-magic if f (V (G)) = {1, 2,. .. , p}. Every super edge-magic (p, q) graph is harmonious, sequential and felicitous whenever it is a tree or(More)
