IN April 1961 it became apparent that an increasing number of patients was attending the out-patients department of the Birmingham and Midland Eye Hospital with a follicular conjunctivitis, and an associated pre-auricular adenitis, which often proceeded to a keratitis. This was soon recognized as an outbreak of epidemic keratoconjunctivitis and therefore precautionary measures were immediately ...

We prove the Strengthened Hanna Neumann Conjecture. We give a more direct cohomological interpretation of the conjecture in terms of “typical” covering maps, and use graph Galois theory to “symmetrize” the conjecture. The conjecture is then related to certain kernel of a morphism of sheaves, and is implied provided these kernels are co-acyclic in the covering cohomology theory. This allows us t...

The understanding and interpretation of unconscious symbolism is one of the main tools of the psychologist. Often he is faced with the task of understanding and recognizing the meaning not only of a particular symbol but also of the whole process of symbol formation. This applies particularly to work with patients who show a disturbance or inhibition in the formation or free use of symbols, as ...

From puberty onward, mating becomes a major focus of thought: Whom shall I date? Shall I stay with my current partner, or look for someone else? Can I find someone better? Will she like me? Will he leave me for someone else? How popular with the opposite sex am I, compared to my peers? These types of questions, which sometimes persist throughout adulthood, point to the complexity of mating deci...

A graph is equitably k-colorable if its vertices can be partitioned into k independent sets in such a way that the number of vertices in any two sets differ by at most one. The smallest k for which such a coloring exists is known as the equitable chromatic number of G and denoted by χ=(G). It is interesting to note that if a graph G is equitably k-colorable, it does not imply that it is equitab...

Atherosclerosis is the main cause of morbidity and mortality in developed countries. Medication, angioplasty, stenting, and bypass operations are currently the means to relieve the symptoms. However, post-angioplasty restenosis and vein graft stenosis limit the efficacy of these operations. Moreover, the post-operational medication of these patients is still far from optimal. The aim of this st...

W hile a PhD candidate, doing my thesis at the Oak Ridge National Laboratory, Biology Division under Dr. Charles Congdon, my introduction to the immune response was studying graft vs. host (GVH) disease as a consequence of bone marrow transplantation in mice. The sequalae of GVH was impressive, and demonstrated the potential of negative clinical consequences of the immune system. The idea of ha...
