Evidence suggests that early exposure to surgical techniques, surgical knowledge and mentors strongly correlates with students’ interest, knowledge and confidence in general surgery as a postgraduate career choice. Preclerkship exposure to surgery and implementation of a formal surgical curriculum is often restricted owing to attending surgeon time commitments and cost limitations. To promote e...

OBJECTIVES To look at why a regional cohort of UK doctors chose a paediatric career and to ascertain views on their career near the end of training year one. DESIGN A 20-item questionnaire was sent to all new regional paediatric specialty trainees. Three focus groups were held with trainees near the end of year one to elicit key themes. SETTING West Midlands Deanery, UK. PARTICIPANTS Twen...

We analyze the phase diagram of a system of spin-1/2 Heisenberg antiferromagnetic chains interacting through a zigzag coupling, also called zigzag ladders. Using bosonization techniques we study how a spin-gap or more generally plateaux in magnetization curves arise in different situations. While for coupled XXZ chains, one has to deal with a recently discovered chiral perturbation, the couplin...

A graph G is called T -unique if any other graph having the same Tutte polynomial as G is isomorphic to G. Recently, there has been much interest in determining T -unique graphs and matroids. For example, de Mier and Noy [A. de Mier, M. Noy, On graphs determined by their Tutte polynomials, Graphs Combin. 20 (2004) 105–119; A. de Mier, M. Noy, Tutte uniqueness of line graphs, Discrete Math. 301 ...

The stability of hole bound states in the t-J model including short-range Coulomb interactions is analyzed using computational techniques on ladders with up to 2330 sites. For a nearest-neighbor ~NN! hole-hole repulsion, the two-holes bound state is surprisingly robust and breaks only when the repulsion is several times the exchange J . At ;10% hole doping the pairs break only for a NN repulsio...
