System protection mechanisms such as access controls can be fooled by authorized but malicious users, masqueraders, and misfeasors. Intrusion detection techniques are therefore used to supplement them. The capacity of these techniques, however, is limited: innocent users may be mistaken for malicious ones while malicious users stay at large. Isolation is a method that has been applied to protec...

Surgical removal of the pancreas in patients with intractable chronic pancreatitis will potentially mitigate the long standing suffering of abdominal pain and improve the quality of life. Nonetheless, the induction of iatrogenic diabetes from surgery becomes irrevocable as the insulin producing islet cells are removed. This novel process of islet isolation (both autoand allo-) involves specific...

BACKGROUND: Lymphovascular ligation before tumour manipulation during colorectal cancer resection is termed the 'no-touch isolation' technique. It aims to reduce the intra-operative dissemination of colorectal cancer cells. Recently, the detection of circulating tumour cells has been enhanced by molecular biology techniques. This paper reviews the evidence for the no-touch isolation technique i...

Modern aircraft flight control relies on a complex network of interacting systems. These systems are safety critical systems, since a failure could have catastrophic consequences. It is therefore necessary to detect and isolate faults in aircraft control system components such as actuators or sensors before the fault is allowed to cause a system failure. Such detection and isolation could poten...

Microbiology in general and clinical microbiology in particular have witnessed important changes during the last few years. Traditional methods of bacteriology and mycology require the isolation of the organism prior to identification and other possible testing. In most cases, culture results are available in 48 to 72 h. Virus isolation in cell cultures and detection of specific antibodies have...

Rare cells are low-abundance cells in a much larger population of background cells. Conventional benchtop techniques have limited capabilities to isolate and analyze rare cells because of their generally low selectivity and significant sample loss. Recent rapid advances in microfluidics have been providing robust solutions to the challenges in the isolation and analysis of rare cells. In additi...

This work presents STR, a geo-distributed, partially replicated transactional data store, which leverages on novel speculative techniques to mask the inter-replica synchronization latency. The theoretical foundations on top of which we built STR is a novel consistency criterion, which we call SPeculative Snapshot Isolation (SPSI). SPSI extends the well-known Snapshot Isolation semantics in an i...

REASONS FOR PERFORMING STUDY The increasing use of modern reproductive techniques in human medicine has led to a higher demand for isolation of motile sperm. Several of these isolation techniques have been adapted for veterinary use and can be applied for the selection of a superior sperm sample from stallion semen. Until recently a major disadvantage of such isolation techniques was the limita...

Sex chromosomes have a large effect on reproductive isolation and play an important role in hybrid inviability. In Drosophila hybrids, X-linked genes have pronounced deleterious effects on fitness in male hybrids, which have only one X chromosome. Several studies have succeeded at locating and identifying recessive X-linked alleles involved in hybrid inviability. Nonetheless, the density of dom...
