In this paper we present an efficient method for interpolating a piecewise-linear surface between two parallel slices, each consisting of an arbitrary number of (possibly nested) polygons that define ‘material’ and ‘non-material’ regions. This problem has applications to medical imaging, geographic information systems, etc. Our method is fully automatic and is guaranteed to produce non-self-int...

The findings of the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) have generated worldwide reaction from clinicians and researchers, including a recent commentary in this journal. Such response was expected for a trial of ALLHAT's size and scope, especially since its results challenged some widely held beliefs. This paper reviews key aspects of the ALLHAT ...

We consider the buckle-driven delamination of biaxially compressed thin films. Telephone-cord-like patterns observed in experiments are explained as a result of the buckling behavior of the film. We perform a stability analysis of a straight blister. A mechanism of instability causing undulations in an advancing finger of delamination is pointed out, which we claim to be the basic phenomenon ex...

©FFPRHC J Fam Plann Reprod Health Care 2007: 33(3) Background In this Commentary we review recent research about the mechanism of action of levonorgestrel emergency contraceptive pills (ECPs) and the population impact of emergency contraception (EC), and we examine the downside of making ECPs available directly from a pharmacist or other non-specialist provider without a prescription. We argue ...

Imagine that you get such certain awesome experience and knowledge by only reading a book. How can? It seems to be greater when a book can be the best thing to discover. Books now will appear in printed and soft file collection. One of them is this book straight from the horse s mouth. It is so usual with the printed books. However, many people sometimes have no space to bring the book for them...

Over last fifteen years, robot technology has become popular in classrooms across our whole educational system. Both engineering and AI educators have developed ways to integrate robots into their teaching. Engineering educators are primarily concerned with engineering science (e.g., feedback control) and process (e.g., design skills). AI educators have different goals—namely, AI educators want...

statement of problem: a recent technique (mbt) has been introduced for easy and efficient orthodontic treatment by means of straight wire fixed appliances. although this technique has many advantages, in space closure stage causes up righting problem in upper incisors, which should be adjusted by applying additional torque in anterior region. purpose: the purpose of this clinical trial was to d...

considering the fact that rocks fail faster under tensile stress, rock tensile strength is of greatimportance in applications such as blasting, rock fragmentation, slope stability, hydraulic fracturing,caprock integrity, and geothermal energy extraction. there are two direct and indirect methods tomeasure tensile strength. since direct methods always encompass difficulties in test setup, indire...

T HE North American Free Trade Agreement (NAFTA) was sold on the basis that it would bring a substantial expansion of US exports to Mexico and boost Mexico’s economic growth. Since its passage, however, not everything has gone as planned. In 1995 — scarcely a year after NAFTA came into effect — Mexico was in the midst of its worst economic crisis in decades. Meanwhile, rather than the anticipat...
