SIR, — DEFRA is to be commended for continuing its policy of postimport testing animals for bluetongue that have been purchased from other eu member states. However, we have grave concerns about how the results of this policy are being interpreted, especially following the recent identification ...

Strategies to Control Trachoma
Drugs, 2009Trachoma is a significant public health problem that is endemic in 57 countries, affecting 40.6 million people and contributing to 4% of the global burden of blindness. Repeated episodes of infection from Chlamydia trachomatis lead to long-term inflammation, scarring of the tarsal conjunctiva and distortion of the upper eyelid with in-turning of ...

Quarterly Journal of Experimental Psychology, 2018
Two tasks (A and B) were designed which required participants to sequentially move through four target positions in a Lissajous display. Task A was designed so that participants could complete the task using either unimanual or bimanual control strategies. Task B was designed so that participants could complete the task using relatively simple or more

Veterinary Record, 2015
Mycobacterium bovis remains a hugely significant animal health and welfare issue. Clinical disease in any affected species must be a consideration for policymakers, with disease eradication as the primary objective. Increasing incidence in ‘domesticated’ species regarded as spill-over hosts such as camelids, pigs, goats, cats and dogs is a salutary ...

Applied Soft Computing, 2016
An evaluation index called "Control Strategy PSO" is developed.It can be applied to other intelligent algorithms.We present a detailed theoretical and empirical analysis. Many variants of particle swarm optimization (PSO) both enhance the performance of the original method and greatly increase its complexity.

SIR, — The field of parasitic disease research has changed considerably in the past few years. The biggest impact has been to revise the advice that was given in the 1970s and 80s, changing the entire philosophy of parasite control and reducing the dependence on anthelmintics ...

Control strategies for ostertagiasis
Veterinary Parasitology, 1988There are currently four major options for control of ostertagiasis and other ruminant gastrointestinal parasites. These are the traditional, suppressive, integrated and strategic approaches. Strategic dosing is the most realistic and beneficial approach for most regions of the world, including the U.S.A.

Introducing Probabilities in Controller Strategies
2015In this paper we propose a basic framework to merge security controllers with probabilistic concepts. This framework provides a first step towards quantitative security achieved by probabilistic controllers. It extends the framework for specification, analysis, and automatic generation of security controllers provided in [21,23] by considering ...
