European wild rabbits (Oryctolagus cuniculus) are frequently translocated for hunting and conservation purposes. Quarantining these animals prior to release reduces the risk of releasing rabbits incubating field infections of myxomatosis or viral haemorrhagic disease (RHD), and it provides a way to vaccinate these animals against both diseases. However the optimal quarantine period needed to ac...

We developed a loop-mediated isothermal amplification (LAMP) method to rapidly diagnose Wheat streak mosaic virus (WSMV) during quarantine inspections of imported wheat, corn, oats, and millet. The LAMP method was developed as a plant quarantine inspection method for the first time, and its simplicity, quickness, specificity and sensitivity were verified compared to current reverse transcriptio...

Quarantine treatment enables export of avocado fruit (Persea americana) to parts of the world that enforce quarantine against fruit fly. The recommended cold-based quarantine treatment (storage at 1.1°C for 14 days) was studied with two commercial avocado cultivars 'Hass' and 'Ettinger' for 2 years. Chilling injuries (CIs) are prevalent in the avocado fruit after cold-quarantine treatment. Henc...

GaAsSb/InP type-II transistors have been fabricated with fT > 325 GHz and fMAX > 275 GHz. This work will examine the layer structure design criteria allowing the fT to improve from 244 GHz to 358 GHz and the effects this has on the corresponding fMAX. Additionally, the process improvements to control the undercut into the active region during the base contact isolation etch will be discussed. T...

Quarantine is one possible solution to limit the propagation of an emerging infectious disease. Typically, infected individuals are removed from the population by avoiding physical contact with healthy individuals. A key factor for the success of a quarantine strategy is the carrying capacity of the facility. This is often a known parameter, while other parameters such as those defining the pop...

During the 2003 Severe Acute Respiratory Syndrome (SARS) outbreak, traditional intervention measures such as quarantine and border control were found to be useful in containing the outbreak. We used laboratory verified SARS case data and the detailed quarantine data in Taiwan, where over 150,000 people were quarantined during the 2003 outbreak, to formulate a mathematical model which incorporat...

Preemptive quarantine through contact-tracing effectively controls emerging infectious diseases. Occasionally this quarantine fails, however, and infected persons are released. The probability of quarantine failure is typically estimated from disease-specific data. Here a simple, exact estimate of the failure rate is derived that does not depend on disease-specific parameters. This estimate is ...

The 2003 severe acute respiratory syndrome (SARS) epidemic came and left swiftly, resulting in more than 8,000 probable cases worldwide and 774 casualties. It is generally believed that quarantine of those individuals suspected of being infected was instrumental in quick containment of the outbreaks. In this work we propose a differential equation model that includes quarantine and other interv...

member of the Hunterian Society of Edinburgh. He started on his career as an assistant to a practitioner in London; and being desirous of visiting foreign parts, he next took employment in the Government mail-packet service, which gave him opportunities of going to the West Indies, and to the Mediterranean, where the odious usage of quarantine was then exercised to its fullest extent. He retain...

In the absence of valid medicines or vaccine, quarantine and isolation strategies are the most important and effective measures against the outbreaks of epidemic diseases such as SARS. This paper discusses the application of the optimal quarantine and isolation strategies for SARS outbreak control via the Pontryagin’s Maximum Principle. We construct a multigroup SARS transmission model for trav...
