Ó. Blasco and S. Pott showed that the supremum of operator norms over L 2 $L^2$ all bicommutators (with same symbol) one-parameter Haar multipliers dominates biparameter dyadic product BMO norm symbol itself. In present work we extend this result to Bloom setting, any exponent 1 < p ? $1<p<\infty$ . The main tool is a new characterization in terms paraproducts two-weight John–Nirenberg inequali...

Having designed a dialogue-capable agent, and evaluated three versions of this humanoid, it is now time to take a step back and look at the issue of humanoid agent design in a larger perspective. In the real world, physicsÑand the workings of natural design and selectionÑdictate the way multimodal creatures look. In the digital world there is much more flexibility (or so weÕd like to think). Th...

Why arenÕt more people engaged in actions that would help mitigate climate change? The psychological Òdragons of inactionÓ that impede green behaviors fall into seven Ògenera,Ó each with multiple ÒspeciesÓ of barriers to pro-environmental behavior. Collectively, they represent a formidable challenge to policy makers, not only because there are so many of these dragons, but also because policy m...

This article investigates the weak distributivity of Boolean ó-algebras satisfying the countable chain condition. It addresses primarily the question when such algebras carry a ó-additive measure. We use as a starting point the problem of John von Neumann stated in 1937 in the Scottish Book. He asked if the countable chain condition and weak distributivity are sufficient for the existence of su...

The collection, seeing compensation, and temporal Ðltering of a high-resolution time-sequence of solar photospheric images is described. A 70 minute time series of cospatial and cotemporal G band 4305 Ó and wideband 4686 Ðltergrams was obtained with the 50 cm Swedish Vacuum Solar Telescope on the Ó island of La Palma, Spain. The 29A ] 70A Ðeld-of-view near disk center contains both an enhanced ...

In this study, a temperature-dependent of the dispersion coefficients is calculated from equation state.The Lennard-Jones LJ (12-6-3) effective pair potential function and simple thermodynamic argumentwith the input PVT data of liquid metals are used to calculate the dispersion coefficients. The dispersioncoefficients ( , , ) 3 6 12 C C C are found to be a linear function of 1/T1+α , where T is...

A similar process can be used when dealing with sample means. If a suYcient number of samples have been taken, and their means plotted, then they begin to take up a normal distribution. It can be shown mathematically that the mean of this distribution (μx) is the same as the population mean (μ). Furthermore, the standard deviation of the distribution is equal to ó/'n, where n is the number of c...
