A careful analysis of the new data of the UA4/2 collaboration reveals that these data give an essentially large value of the ρ = ReT (s, t)/Im(s, t) that does not contradict the early UA4 experiment. There is the reason to think also that this experiment reveals for the first time a real possibility of the existence of the spin-flip amplitude at superhigh energies in the range of small transfer...

A new solution strategy for the problem of induction has been developed based on a priori advantages regret-weighted meta-induction (RW) in prediction tasks. These seem to contradict no-free lunch (NFL) theorem. In this paper, NFL challenge is dissolved by three novel results: (1) RW enjoys free lunches long run. (2) Yet, theorem applies iterated tasks, because distribution underlying it assign...

Estimates of the amount stormwater captured by urban trees have focused on rainfall intercepted leaves and branches, while runoff that flows into a tree pit from surrounding sidewalk has not been well quantified. This study estimated infiltrates first calculating tributary drainage area drains to street pits varying widths slopes. With Manhattan, New York, as case study, used i-Tree software fi...

We present a quantum-mechanical calculation of Stark line widths from electron-ion collisions for the 2s1/2−2p1/2,3/2, λ = 2066 and 2067 Å, resonance transitions in B III. The results confirm the previous quantum-mechanical Rmatrix calculations but contradict recent measurements and semi-classical and some semi-empirical calculations. The differences between the calculations can be attributed t...

We study how the mechanisms of choice influence preferences when animals face more than 2 alternatives simultaneously. Choice mechanisms can be hierarchical (if alternatives are assigned to categories by their similarity and choice is between categories) or simultaneous (if options enter the choice process individually, each with its own value). The latter, although simpler, can lead to counter...

EditorÐRahman and colleagues 1 make the interesting observation that obstructed breathing in post-operative patients was more common when they were awake than when they were asleep. This seems to contradict our study 2 where we found obstructed breathing postoperatively only when patients were asleep. There were important differences between the two studies. We 2 divided 32 patients into two eq...

2-phosphonobutane-1,2,4-tricarboxylic acid is(pbtc) a member of phosphonate family, and used as corrosion and scale inhibitor in cooling water systems. phosphonocarboxylates as a member of organophosphorus compounds have c-p and p-o bonds in their structures. pbtc is mainly used as carbonate scale inhibitor (caco3), sulphate scale inhibitor (caso4), corrosion inhibitor of low alloyed steel, eff...

(a) Prove that for each integer n > 1 there are infinitely many (Z/nZ)-extensions of Q ramified at only one prime. (b) Prove that for each integer n > 2 there are no (Z/nZ)2-extensions of Q ramified at only one prime. Why does this not contradict the fact that (Z/pZ)2-extensions of Qp exists for every p? (c) Given an explicit example of a (Z/2Z)2-extension of Q ramified at only one prime (with ...
