The LEP investigation of the B 0 d and B 0 s oscillations and of the Cabibbo-Kobayashi-Maskawa matrix element |V ub | improve the constraints on the other elements of this matrix. From a fit to the experimental data and the theory calculations it is possible to determine the vertex of the unitarity triangle as:

BACKGROUND With the decrease in junior doctor hours, the advent of specialist registrars, and the availability of highly trained and experienced nursing personnel, the service needs of patients with chronic respiratory diseases attending routine outpatient clinics may be better provided by appropriately trained nurse practitioners. METHODS A randomised controlled crossover trial was used to c...

OBJECTIVE To compare the cost effectiveness of general practitioners and nurse practitioners as first point of contact in primary care. DESIGN Multicentre randomised controlled trial of patients requesting an appointment the same day. SETTING 20 general practices in England and Wales. PARTICIPANTS 1716 patients were eligible for randomisation, of whom 1316 agreed to randomisation and 1303...

This paper presents a new method for computing whether or not two triangles in three dimensions intersect. The code is very efficient and requires minimum arithmetic precision. Indeed, all branching decisions are carried out by evaluating the signs of degree three polynomials. In addition, an efficient test is proposed for the two-dimensional case. Key-words: geometric predicates, low degree pr...

OBJECTIVES To establish the relative cost effectiveness of postnatal support in the community in addition to the usual care provided by community midwives. DESIGN Randomised controlled trial with six month follow up. SETTING Recruitment in a university teaching hospital and care provided in women's homes. PARTICIPANTS 623 postnatal women allocated at random to intervention (311) or contro...

AIM Rotavirus is the leading cause of acute gastroenteritis in children. Two rotavirus vaccines (RotaTeq and Rotarix) have recently completed clinical trials. We investigated whether routine infant immunisation with either vaccine can be cost effective. METHODS We compared costs and outcomes of vaccination using a cohort model, following children over the first 5 years of life. We estimated h...

BACKGROUND Children with congenital hearing impairment benefit from early detection and management of their hearing loss. These and related considerations led to the recommendation of universal newborn hearing screening. In 2001 the first phase of a national Newborn Hearing Screening Programme (NHSP) was implemented in England. Objective of this study was to assess costs and effectiveness for h...

Last autumn, as you will remember, men invalided with dysentery from the Peninsula of Gallipoli came in large numbers into English military hospitals. As they grew better they had much to tell of Mudros and of the fighting on the northern shores of the Dardanelles. Their stories called up memories of another and more successful expedition which gathered in the great Bay of Lemnos three thousand...
