In this paper, topological properties of Wijsman hyperspaces are investigated. We study the existence of isolated points in Wijsman hyperspaces. We show that every Tychonoff space can be embedded as a closed subspace in the Wijsman hyperspace of a complete metric space which is locally R.

We report 60 and 90 m observations of seven millisecond pulsars with the Infrared Space Observatory. The pulsar PSR B1257+12 is orbited by three planets, and other millisecond pulsars may be orbited by dust disks that represent planets that failed to form or their residue. We do not detect any infrared emission from the seven pulsars in our sample, and typical upper limits are 100 mJy. Using a ...

A panel of hybrids previously derived from fusions between a chemically transformed hamster cell line and normal human fibroblasts (A. Stoler and N. Bouck, Proc. Natl. Acad. Sci. USA, 82: 570-574, 1985) has been used to test whether or not anchorage independence, lack of actin cables, and angiogenic activity, three characteristics of transformed cells considered necessary but not sufficient for...

this paper tries to survey the independence of central bank of iran and its relationship to inflation by using the data of 56 developing countries during 1990s. the results signifies that there are no significant relationship between inflation and the independence of central banks in these countries. in other words, according to the existing evidences, not all the developing countries with high...

Recently, uniqueness theorems were constructed for the representation used in Loop Quantum Gravity. We explore the existence of alternate representations by weakening the assumptions of the so called LOST uniqueness theorem. The weakened assumptions seem physically reasonable and retain the key requirement of explicit background independence. For simplicity, we restrict attention to the case of...

The struggle for national independence is often led by a charismatic movement. Once independence has been gained, such movements tend, to use Max Weber's terminology, to become "routinized" by developing either "traditional" or "bureaucratic" structures. The outcome of the conflict between these two tendencies to a large extent determines the degree of political stability, the extent of civil r...

The study of hysteresis can be traced back to the 19th century. key characteristics are rate independence and dependence. A typical system with is reducer. In industrial sector, phenomenon a reducer often illustrated by lost motion, which always consistent default. paper, hysteretic model considering geometric errors established. Theoretically, found mostly maintain dependence rather than indep...
