The United Kingdom implemented a containment strategy for pandemic (H1N1) 2009 through administering antiviral agents (AVs) to patients and their close contacts. This observational household cohort study describes the effect of AVs on household transmission. We followed 285 confirmed primary cases in 259 households with 761 contacts. At 2 weeks, the… (More)

BACKGROUND
Infectious intestinal disease (IID), usually presenting as diarrhoea and vomiting, is frequently preventable. Though often mild and self-limiting, its commonness makes IID an important public health problem. In the mid 1990s around 1 in 5 people in England suffered from IID a year, costing around pound0.75 billion. No routine information source… (More)

The geometric form of a conjecture associated with the names of Loewner and Carath eodory states that near an isolated umbilic in a smooth surface in R 3 , the principal line elds must have index 1. Real solutions of the diierential equation @ 2 z ! = g , where the complex function g is given only up to multiplication by a positive function, are intimately… (More)

There is a paucity of data regarding the potential for pediatric cervical spine injury as a result of acceleration of the head with no direct impact during automotive crashes. Sled tests were conducted using a 3-year-old anthropomorphic test device (ATD) to investigate the effect of restraint type and crash severity on the risk of pediatric inertial neck… (More)

In classical surface theory there are but few known examples of surfaces admitting nontrivial isometric deformations and fewer still non-simply-connected ones. We consider the isometric deformability question for an immersion x : M → R 3 of an oriented non-simply-connected surface with constant mean curvature H. We prove that the space of all isometric… (More)

The paper treats the isometric deformability of non-simply-connected constant mean curvature surfaces which are neither assumed embedded nor complete. We prove that if a smooth oriented surface M immersed in R 3 admits a nontrivial isometric deformation with constant mean curvature H then every cycle in M has vanishing flux and, when H = 0, also vanishing… (More)

— Natural or man-made disasters can partition networks while threatening human lives. Because conventional Mobile Ad-Hoc Networks (MANETs) cannot route messages across partitions, they may not adequately support relief efforts. To forward messages across partitions, delay-tolerant networks (DTNs) exploit in-network storage and mobility. Many previous DTN… (More)

The character of the principal foliations on a smooth surface in R 3 is not well understood, in particular, whether there are geometric or topo-logical restrictions on their singularities (umbilics) distinguishing them from the singularities of arbitrary smooth foliations on an abstract smooth surface. The longstanding Carathéodory Conjecture hypothesizes… (More)

Public health risk communication during emergencies should be rapid and accurate in order to allow the audience to take steps to prevent adverse outcomes. Delays to official communications may cause unnecessary anxiety due to uncertainty or inaccurate information circulating within the at-risk group. Modern electronic communications present opportunities… (More)
