As an extension of the class of half condensed domains introduced by D.D. Anderson and Dumitrescu, we introduce and study the class of almost condensed domains. An integral domain D is almost condensed if whenever 0 ̸= z ∈ IJ with I, J ideals of D, there exist I ′, J ′ ideals of D such that I ′ ⊆ Iw, J ′ ⊆ Jw and zD = (I ′J )w. In 1983, D.F. Anderson and D.E. Dobbs [13] called an integral domain...

The key insight of Bogoliubov is that although the mean-field Hamiltonian (1) is clearly not diagonal in the space of states created by the operators ck,↑/↓, it may be diagonal in a basis of states created by operators related to these via a simple SU2 transformation. Indeed, it may be the case that ‘electrons’ and ‘holes’ are the wrong degrees of freedom to consider; we should at least look to...

Milk is a bulky product, expensive to transport, and very susceptible to contamination, which in a short time renders it unpalatable. In its natural state it contains al^out 87 per cent of water, which is a comparatively worthless constituent. ' Efforts to reduce the water content of milk, leaving the solids in ; a more concentrated form without destroying their food value, and at the same time...

The American Physical Society (APS) March Meeting of condensed matter physics has grown to nearly 10,000 participants, comprises 23 individual APS groups, and even warrants its own hashtag (#apsmarch). Here we analyze the text and data from March Meeting abstracts of the past nine years and discuss trends in condensed matter physics over this time period. We find that in comparison to atomic, m...

Abstract. Even though Object Orientation has been proven to be an effective programming paradigm for software development, it has not been shown to be an ideal solution for the development of large scale parallel and distributed systems. There are a number of reasons for this: the parallelism and synchronisation in these systems has to be explicitly managed by the programmer; few Object Oriente...

Fabrication of biocompatible and non-toxic magnetically-directed nanocarriers for targeted delivery is very crucial for nanomedicine application, especially for tumor therapy. In this talk, the successful synthesis of ibuprofen loaded magnetic hollow silica porous nanospheres (Ib-MHSPNs) and solid lipid nanoparticles (Ib-MSLNs) will be presented. The MHSPNs and MSLNs were investigated by transm...

In this paper we suggest determinations as a representation of knowledge that should be easy to understand. We brieey review determinations, which can be displayed in a tabular format, and their use in prediction , which involves a simple matching process. We describe ConDet, an algorithm that uses feature selection to construct determinations from training data, augmented by a condensation pro...

The first who reported [1-3] Palladium catalysed fusion of hydrogen nuclei to Helium at room temperature were German researchers Paneth and Peters in 1926. They retracted their work for unknown reasons. Lochte-Holtgreven studied LENR in the 1970s and reported [4-5] neutrons when electrically exploding deuterated liquids. He was director of the institute for experimental physics at the Christian...
