We derive new duality relations that link the energy of configurations associated with a class of soft pair potentials to the corresponding energy of the dual (Fourier-transformed) potential. We apply them by showing how information about the classical ground states of short-ranged potentials can be used to draw new conclusions about the nature of the ground states of long-ranged potentials and...

It is well known that if a function from set A to set B has a right inverse then the function is a surjection and the right inverse is an injection. For finite sets, the number of functions, injections, and surjections can also be counted. Relations generalize functions: do similar results exist for relations? This paper proves several new results concerning binary relations. For finite sets, w...

Recent advances in the Wnt signaling field reveal new components, such as a G protein and an atypical receptor tyrosine kinase, and novel connections between known components. In addition, different subcellular localization of receptors may help to explain distinctions between canonical and noncanonical Wnt pathway activity.

We obtain several combinatorial results about chains, cycles and orbits of the elements of the symmetric inverse semigroup ISn and the set Tn of nilpotent elements in ISn. We also get some estimates for the growth of |ISn| and |Tn|, and study random products of elements from ISn.

The paper discusses comparative generic sentences As are F-er than Bs—girls do better than boys in grade school, for example—which pose severe problems for extant accounts. In their stead, the paper proposes reconceiving the LF of generic sentences as more closely akin to that of sentences containing non-generic plurals, paradigmatically plural definite descriptions. Given this one crucial chan...

Ward sisters/managers are without doubt the professional gate keepers of the ward environment yet there are activities in that environment for which they do not seem to take full responsibility, namely that of the clinical learning of nursing students. The aim of this study was to investigate the role of the ward manager in creating a conducive clinical learning environment for nursing students...

Mark Silk has proposed in Unsecular Media that journalists operate with a limited series of topoi and that these are borrowed from religion. Silk thus claims when journalists write about religion, they do so in a way that ultimately supports religious values. In this study, I apply topic analysis to recent news coverage of Jesse Jackson’s marital infidelity to determine the extent to which the ...

Research on mass communications and on the acceptance of new farm practices may be characterized as an interest in campaigns to gain a acceptance of change. Despite their shared problems, these two fields have shown no interest in each other. However, very recently, as the student of mass communications began to revise his image of an atomized mass society, there have been signs of growing conv...

Using 100 clinical cases, we examined the construct validity of the Mutuality of Autonomy (MOA) Scale (Urist, 1977) using Westen and Rosenthal's (2003) r(contrast - construct validity (CV)) procedure for quantifying a pattern of convergent-discriminant relationships between a target measure and a set of criterion variables. Our 15 criterion variables included the Comprehensive System (CS; Exner...

ion of the morphism 〈u, v〉 in the subscone from 〈S,m,A〉⊗̃〈S1,m1, A1〉 to 〈S2,m2, A2〉 is then the pair 〈ẽ2 ◦ ũ,Λ(v)〉 given by the diagram: S  m // ũ ## Λ(u◦e.1) 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 |A|
