Science cannot prove a negative, but, where their children are concerned, parents want to be assured that risk is zero. Would establishing a comprehensive “Richter scale” of risks remove that misunderstanding? If not, then what accounts for miscommunication of risk and how might it be overcome? In this article I try to provide answers by considering public perception of three risks, each of a d...

Nepal experienced a devastating earthquake measuring 7.8 Richter scale on 25th April 2015. Although the heightened effects were secondary to trauma, the indirect effects were also of prime importance. We came across different dermatoses, directly or indirectly secondary to earthquake. We here present an audit of the cutaneous effects following four months of the major shock presenting to a tert...

Few cases of secondary CD5+ diffuse large B-cell lymphoma (DLBCL) that are not Richter syndrome have been reported previously. We report 9 cases of non-Richter syndrome secondary CD5+ DLBCL. Among 529 cases of DLBCL, 38 (7.2%) were CD5+ DLBCL, including 9 of secondary CD5+ DLBCL. Five cases gained CD5 expression during the clinical course of DLBCL (group 1). Three cases showed transformation fr...

Bonnington and Richter defined the cycle space of an infinite graph to consist of the sets of edges of subgraphs having even degree at every vertex. Diestel and Kühn introduced a different cycle space of infinite graphs based on allowing infinite circuits. A more general point of view was taken by Vella and Richter, thereby unifying these cycle spaces. In particular, different compactifications...
