Medical Image Analysis, 2006
Since their debut in 1987, snakes (active contour models) have become a standard image analysis technique with several variants now in common use. We present a framework called "United Snakes", which has two key features. First, it unifies the most popular snake variants, including finite difference, B-spline, and Hermite polynomial snakes in a ...

Canadian Journal of Mathematics, 1977
Dirichlet was the first to give an ingenious proof of the exact (finite) number of elements in the basis of the multiplicative group of units in any algebraic number field of arbitrary degree n. These elements are called fundamental units. If the field is real and its generating number is a real root of a polynomial over Q of degree n﹜ having r1 real ...

Special radiation units and/or SI units?
Physics in Medicine & Biology, 1974The publication of my letter “SI Units in Radiology and Radiation Measurement” in your journal (Liden, 1973) was appreciated by the International Commission on Radiation Units and Measurements, ICRU. The interest of many readers has obviously been awakened by this letter, which also appeared in several other journals.

Journal of Theoretical Biology, 1963
It is plainly impossible to deal with the problem of ‘the cell as a unit’ more than perfunctorily in the limited space of a brief essay. The most one can hope to achieve is to set the problem in the proper perspective by an examination, however cursory, of whether ‘cell biology’ has any factual claim to the status of an autonomous discipline in the ...

Abstract Having considered the view of the British political elite in London and the implications of wartime declarations and Anglo-American differences in the preceding chapters, this chapter opens a section of the book that develops our enquiry into what the war did to the Empire and Britain’s prospects of holding on to it by looking ...

Experiences with Unit-to-Unit Variations in Tablets
Journal of Pharmaceutical Sciences, 1964The literature reports on the subject of interunit dosage and weight variations of tablets indicate that past studies were mainly concerned with analyzing the finished product to detect gross departures from the desired quality. These studies, however, were cognizant of the several stages of manufacture before the compression step could contribute to ...

THE INTENSIVE CARE UNIT AS A TRAUMA UNIT
Surgical Clinics of North America, 2000The ICU plays a pivotal role in the care of the critically injured patient. From the resuscitative phase of care through the life-support phases and finally the recovery phase, advances in ICU care have been made in recent years. As a result, an improved outcome for traumatically injured patients often is seen, and the third peak in the trimodal ...

Abstract United and uniting churches have made a very significant contribution to the ecumenical movement. In seeking to assess that contribution, the chapter first defines what these churches are, considers the different types of union that have been created, examines the characteristics of these churches, and looks at the theological ...

Unit of observation versus unit of analysis
BMJ, 2014Researchers investigated the effects of a school based educational programme aimed at reducing the consumption of carbonated drinks to prevent weight gain in children aged 7-11 years. A cluster randomised controlled trial study design was used. The programme, which was delivered over one school year, focused on promoting a healthy diet.
