We consider incidences among colored sets of lines in R and examine whether the existence of certain concurrences between lines of k colors force the existence of at least one concurrence between lines of k + 1 colors. This question is relevant for problems in 3D reconstruction in computer vision. 2012 ACM Subject Classification Theory of computation → Randomness, geometry and discrete structur...

The finding that the Ebbinghaus/Titchener illusion deceives perception but not grasping is usually seen as strong evidence for Goodale and Milner's (1992) notion of two parallel visual systems, one being conscious and deceived by the illusion (vision-for-perception) and the other being unconscious and not deceived (vision-for-action). However, this finding is controversial and led to studies wi...

Modern programming languages, such as C++ and Java, provide a sequentially consistent (SC) memory model for well-behaved programs that follow a certain synchronisation discipline, e.g., for those that are data-race free (DRF). However, performance-critical libraries often violate the discipline by using lowlevel hardware primitives, which have a weaker semantics. In such scenarios, it is import...

Hector et al. (1) reported on BIODEPTH, a major international experiment on the response of plant productivity to variation in the number of plant species. They found “an overall loglinear reduction of average aboveground biomass with loss of species,” leading to what the accompanying Perspective (2) described as “a rule of thumb—that each halving of diversity leads to a 10 to 20% reduction in ...

We analyze two different feature selection problems: finding a minimal feature set optimal for classification (MINIMAL-OPTIMAL) vs. finding all features relevant to the target variable (ALLRELEVANT). The latter problem is motivated by recent applications within bioinformatics, particularly gene expression analysis. For both problems, we identify classes of data distributions for which there exi...

Recent studies have demonstrated that human societies are hierarchically structured with a consistent scaling ratio across successive layers of the social network; each layer of the network is between three and four times the size of the preceding (smaller) grouping level. Here we show that similar relationships hold for four mammalian taxa living in multi-level social systems. For elephant (Lo...

the effects of a prolonged oral administration of methylthiouracil was studied on the electrophoretically - separated serum protein fractions in 24 dogs. though the statistical mean of changes in serum albumin and alpha2 globulin were highly significant but the individual alterations were not consistent and therefore on the basis of the available data there does not seem to be a characteristic ...

Small Area estimation is a technique used to estimate parameters of subpopulations with small sample sizes.  Small area estimation is needed  in obtaining information on a small area, such as sub-district or village.  Generally, in some cases, small area estimation uses parametric modeling.  But in fact, a lot of models have no linear relationship between the small area average and the covariat...
