An interpretation of a theory may be defined as a set of rules for going from mathematical statements to statements about reality. In particular, given an initial state vector and the Hamiltonian governing its evolution, an interpretation of quantum theory should enable one to say which are the states which might be realized in nature, and their probabilities of realization. The famous so-calle...

'Could have done otherwise', action sentences and anaphora HELEN STEWARD What does it mean to say of a certain agent, S, that he or she could have done otherwise? Clearly, it means nothing at all, unless the anaphoric devices within the sentence have been anchored to definite antecedents. In this paper, I shall argue that there may be more ways of effecting this anchoring than is commonly suppo...

Creolization is the expansion of a simplified pidgin into a more complex language called a creole. Various theories have been proposed to explain this transition; most are attempts to explain who created the creole, adults or children, and refer to processes of first or second language acquisition. However, using traditional methods of investigation, this issue has been difficult to resolve. To...

http://pdm.medicine.wisc.edu Prehospital and Disaster Medicine Evaluations of the processes involved in an intervention are similar to the way in which diagnoses and treatments are defined in clinical medicine. Diagnoses and interventions cannot be accomplished without knowing the physiology/pathophysiology of the organ system(s) involved. Therapy is directed at the pathophysiology. As noted in...

PURPOSE To discuss the role of membrane androgen receptors and to investigate the potential role of testosterone-albumin conjugate in the prostate cancer (PCa) treatment. MATERIALS AND METHODS We identified studies published from 1990 onwards by searching the MEDLINE database of the National Library of Medicine. Initial search terms were "androgen receptors, cytoplasmic androgen receptor, and...

All potassium channels share a common architecture consisting of their pore module with two transmembrane domains and a conserved filter region that selects for K ions. The current view is that the plethora of complex K channels in eukaryotes evolved from a pore module precursor via gene fusions and gene duplications. Here we suggest that this pore precursor might have originated from viruses. ...

We examine the possibility that a nearby supernova explosion could have caused one or more of the mass extinctions identified by paleontologists. We discuss the possible rate of such events in the light of the recent suggested identification of Geminga as a supernova remnant less than 100 parsec (pc) away and the discovery of a millisecond pulsar about 150 pc away and observations of SN 1987A. ...

Introduction: Physical sedimentology experiments using a 39% concentration of sulfuric acid have produced three distinct features, which are similar to features seen on Mars. However, these sedimen-tary features could not be created using pure water in the laboratory. These three features include deeply-incised, narrow channels, cracks that run parallel to the flow direction, and circular depre...

The case is examined of the UK Department of Communities and Local Government (CLG) FiReControl Project (which was terminated in December 2010 at a loss of £469 million) in the light of the influential report by the Institute for Government’s (IfG) ‘System Error: fixing the flaws in government IT’ report which argues that the UK government should tackle its continuing history of failed IT proje...
