In this paper we connect selection principles on a topological space to corresponding one of its hyperspaces. We unify techniques and generalize theorems from the known results about for common hyperspace constructions. This includes Lj.D.R. Ko\v{c}inac, Z. Li, others. use games work with strategies various strengths these games. The are primarily abstract versions Rothberger, Menger, Hurewicz ...

ELECTEOCARDIOGRAPHIC changes after myocardial injury were first described exactly half a century ago when Eppinger and Rothberger, using an esophageal-rectal lead, noted the "disappearance of the valley between the R and T waves" in dogs which had received injections of 20 per cent silver nitrate solution into the left ventricle. Pardee, in 1920, was the first to note S-T segment changes in a p...

Many geospatial science subdisciplines analyze variables that vary over both space and time. The space-time autoregressive (STAR) model is one specification formulated to describe such data. This paper summarizes STAR specifications that parallel geostatistical model specifications commonly used to describe space-time variation, with the goal of establishing synergies between these two modeling...

For synthesising efficient asynchronous circuits from STGs one has to deal with the state space explosion problem. For this purpose STG decomposition was introduced by Chu and improved by Vogler and Wollowski. Here, we present the tool DesiJ which is the implementation of STG decomposition and proposed by Vogler and several other optimisations.

We study the merging of star clusters out of cluster aggregates similar to Knot S in the Antennae on orbits close to the one of ω Cen by carrying out high resolution numerical N-body simulations. We want to constrain the parameter space which is able to produce merger objects with similar properties as ω Cen.

— A point P on a smooth hypersurface X of degree d in PN is called a star point if and only if the intersection of X with the embedded tangent space TP (X) is a cone with vertex P . This notion is a generalization of total inflection points on plane curves and Eckardt points on smooth cubic surfaces in P3. We generalize results on the configuration space of total inflection points on plane curv...

We establish uniqueness of ground states u(x) > 0 for the L-critical boson star equation √ −∆u − (|x| ∗ |u|)u = −u, in R. The proof blends variational arguments with the harmonic extension to the halfspace R + . Apart from uniqueness, we also show radiality of ground states (up to translations) and the nondegeneracy of the linearization. Our results provide an indispensable basis for the blowup...

We have recently measured the angle between the spin and orbital angular momenta of PSR B1534+12 to be either 25 ± 4 or 155 ± 4. This misalignment was almost certainly caused by an asymmetry in the supernova explosion that formed its companion neutron star. Here we combine the misalignment measurement with measurements of the pulsar and companion masses, the orbital elements, proper motion, and...

Natural (such as lunar) occultations have long been used to study sources on small angular scales, while coronographs have been used to study high contrast sources. We propose launching the Big Occulting Steerable Satellite (BOSS), a large steerable occulting satellite to combine both of these techniques. BOSS will have several advantages over standard occulting bodies. BOSS would block all but...
