INTRODUCTION Hip fractures in the elderly are associated with multiple comorbidities. MATERIALS AND METHODS We prospectively surveyed and went through all relevant medical records of 70 consecutive patients admitted to Singapore General Hospital following either a cervical or intertrochanteric femoral fracture from late February to May 2004. The total hospitalisation cost for each patient was...

Our goal is to study type containment, some variations on the type-containment relation, and how it can be extended to other programming language features such as products, side effects, existential types. We will study some language meta-theoretical properties. Notre but est d’étudier le type containment, quelques variantes sur la relation de type containment, et comment elle peut être étendue...

This paper applies Reckless’ theory of containment to the problem of unethical business decision making. Containment theory asserts that deviance will occur when controls are weakened to the point of being insufficient to contain motivated behavior in the presence of an unethical opportunity. The theory accounts for the presence of inner controls and outer controls, as well as factors that push...

This paper investigates the reduced-order observer-based containment control problems of general linear multi-agent systems (MASs) with multiple interaction leaders. Assuming that (A, B, C) is stabilizable and detectable and the directed graph is weakly connected, we establish the necessary and sufficient containment control criteria for continuous-time MASs and discrete-time MASs, respectively...

The inverted index is widely used in the existing information retrieval field. In order to support containment queries for structured documents such as XML, it needs to be extended. Previous work suggested an extension in storing the inverted index for XML documents and processing containment queries, and compared two implementation options: using an RDBMS and using an Information Retrieval (IR...

A finite element analysis is used to study the impact and the containment aspects of rotor blade fragments that are produced during a aircraft jet engine rotor failure. The impact and containment studies are performed on a ring-type containment structure and various fragment types are considered in this study. For each type of fragment, the ring thickness is varied incrementally and the ring re...

We present a new algorithm for the two-dimensional translational containment problem: nd translations for k polygons which place them inside a polygonal container without overlapping. Both the polygons and the container can be nonconvex. The algorithm is based on mathematical programming principles. We generalize our containment approach to solve minimal enclosure problems. We give algorithms t...

Corrosion damage has been found in a number of nuclear power plant containment structures, and this could degrade the pressure capacity of the vessel. This has prompted concerns regarding the capacity of corroded containments to withstand accident loadings. For the low-carbon, low-strength steels used in containments, the effect of corrosion on material properties is discussed in this report, a...

Query containment is a fundamental algorithmic task in database query processing and optimization. Under set semantics, the query-containment problem for conjunctive queries has long been known to be NP-complete. SQL queries, however, are typically evaluated under bag semantics and return multisets as answers, since duplicates are not eliminated unless explicitly specified. The exact complexity...

Phylogenetic trees and networks are leaf-labelled graphs that are used to describe evolutionary histories of species. The Tree Containment problem asks whether a given phylogenetic tree is embedded in a given phylogenetic network. Given a phylogenetic network and a cluster of species, the Cluster Containment problem asks whether the given cluster is a cluster of some phylogenetic tree embedded ...
