We consider the one-dimensional asymmetric simple exclusion process in which particles jump to the right at rate p and to the left at rate 1 − p, interacting by exclusion. Suppose that the initial state has first-class particles to the left of the origin, a second class particle at the origin, a third class particle at site 1 and holes to the right of site 1. We show that the probability that t...

We give an excluded-minor characterization for the class of matroids M in which M\e or M/e is binary for all e in E(M). This class is closely related to the class of matroids in which every member is binary or can be obtained from a binary matroid by relaxing a circuithyperplane. We also provide an excluded-minor characterization for the second class.

OBJECTIVE This study was carried out to determine the place of lecture as a mode of instruction in undergraduate medical education by examining the views of the students about some selected aspects of the lecturing sessions and their ability to recall the varying percentages of the content of the delivered lecture after a specified period of time. METHODS An observational cross sectional stud...

Generalized Dilaton Theories in two dimensions coupled to Dirac fermions are subjected to constraint analysis. Three first class secondary constraints are found, corresponding to one local Lorentz symmetry and two diffeomorphisms. Moreover, the system also yields second class constraints from the fermions. The algebra of first class constraints is calculated in some detail, and is found to be r...

INTRODUCTION Masters Students are major stakeholders in undergraduate medical education but their contribution has not been documented in Uganda. The aim of the study was to explore and document views and experiences of undergraduate students regarding the role of masters students as educators in four Ugandan medical schools. METHODS This was a cross-sectional descriptive study using qualitat...

Among educators, the promotion of undergraduate research is a much debated topic, with issues arising from questions as to how it can be integrated with undergraduate degree programmes and how to structure its delivery. Undergraduate research is also considered important by employers, as can be seen in case of the computer game development and visual effects industries who demand that universit...
