Percolation beyond Z D , Many Questions and a Few Answers

A comprehensive study of percolation in a more general context than the usual Z d setting is proposed, with particular focus on Cayley graphs, almost transitive graphs, and planar graphs. Results concerning uniqueness of innnite clusters and inequalities for the critical value p c are given, and a simple planar example exhibiting uniqueness and non-uniqueness for diierent p > p c is analyzed. N...

Percolation beyond Zz, Many Questions and a Few Answers

A comprehensive study of percolation in a more general context than the usual Z d setting is proposed, with particular focus on Cayley graphs, almost transitive graphs, and planar graphs. Results concerning uniqueness of infinite clusters and inequalities for the critical value pc are given, and a simple planar example exhibiting uniqueness and non-uniqueness for different p > pc is analyzed.

Many Questions and Few Answers: On Conversión in English

Conversión is a well-known word-formation process which, a priori, seems relatively easy to identify. However, a cióse look at its basics brings to light some critical questions which still remain unanswered to this day. The very nature of this operation, and the concepts of full and partial conversión are therefore here examined in the light of a need for explicit criteria for recognition of a...

Use of biomarkers in sepsis: many questions, few answers

Why do we use biomarkers in sepsis? There are several answers to this question. Some researchers argue that biomarkers are used to assess the prognosis of septic patients, (1) but why should we use a biomarker merely to determine whether a patient has a higher risk of death when currently available interventions are not able to modify the prognosis? (2) As we all know, dozens of randomized cont...
