It is a natural problem to investigate the set of what we will call exceptional points for S, i.e. points which are neither density points of S, nor those of R\S. Note that this is a topological notion, since as far as measure theory is concerned, there are no such exceptional points. First, we quantify the notion of exceptional point: given a measurable S ⊂ R and 0 ≤ δ ≤ 1/2, we will call p ∈ ...

in this investigation wer studied the effect of dopaminergic system on the conflict behavior in rat, using vogel’s test. the related drugs were injected intraperitonealy (ip), and produced the following results:diazepam at doses of 0.5 and 1 mg/kg increased the lick –shock responses in the vogel’s thest. quinpirole (d2-agnosit), at doses of 0.1 and 10 mg/kg, increased the confict responses, whe...

We show that professional soccer players and their coaches exhibit reference-dependent behavior during matches. Controlling for the state of the match and for unobserved heterogeneity, we show on a minute-by-minute basis that players breach the rules of the game, measured by the referee’s assignment of cards, significantly more often if their teams are behind the expected match outcome, measure...

Let S be a nonempty bounded set in R2. Then S is staxshaped if and only if every 3 or fewer boundary points of S are clearly visible via S from a common point of S. The number 3 is best possible.

Let Γ be a topological semigroup acting on a topological space X, and let Γ0 be a subsemigroup of Γ. We give general conditions ensuring that Γ and Γ0 have the same transitive points.

The transfer of council estates into housing association (HA) ownership has transformed the structure of social housing provision across Britain; in half of English local authorities council housing is a thing of the past. From 1997, stock transfer extended beyond rural shire districts, with urban estates accounting for the majority of properties being handed to new social landlords. This study...

purpose: the goal of this study was to compare differences in the mean heterophoria and fusional amplitudes before and after photorefractive keratectomy (prk) for myopia. methods: in a prospective controlled study, myopic patients were treated with aspheric and wavefront-guided (personalized) prk. the manifest refraction, visual acuity, fusional amplitudes and heterophoria were evaluated preope...
