This paper considers the means by which mergers are assessed by competition authorities in oligopolistic markets. The focus of the paper is on whether a merger would lead to the emergence of conscious parallel behaviour arising from the joint dominance of the leading players. This assessment is typically conducted informally relying on a checklist of known market conditions that support the for...

Employing multiple paths for achieving high capability and robustness has some obvious benefits. New wireless technologies are giving more Internet access modes for notebooks and smart phones. However, most multipath protocols may not get acceptable throughput if reliable transmission is guaranteed. For some cases, the situation may even worse than using single path only. The main reason has st...

This paper considers a class of one-dimensional solidification problem in which kinetic undercooling is incorporated into the temperature condition at the interface. A model problem with nonlinear kinetic law is considered. The main result is an existence theorem. The mathematical effects of the kinetic term are discussed

ALL modern authorities are agreed that gumma of muscle is now a relatively rare manifestation of syphilis. The condition is adequately described by Harrison and Lees who state that the triceps, biceps, sterno-mastoid, tongue, rectus abdominis and the calf muscles are most commonly involved. The gummata may retrogress and undergo calcification, or even ossification, or may break through the skin...
