Blind source separation using second-order cyclostationary statistics

This paper studies the blind source separation (BSS) problem with the assumption that the source signals are cyclostationary. Identifiability and separability criteria based on second-order cyclostationary statistics (SOCS) alone are derived. The identifiability condition is used to define an appropriate contrast function. An iterative algorithm (ATH2) is derived to minimize this contrast function. This algorithm separates the sources even when they do not have distinct cycle frequencies .

Dispersion statistics and a sampling plan for Helicoverpa (Lepidoptera : Noctuidae) on fresh-market tomatoes (Lycopersicon esculentum)

Helicoverpa spp. is the primary pest in the Australian fresh-market tomato industry. We describe the spatial distribution of Helicoverpa spp. eggs on fresh-market tomato crops in the Goulburn Valley region of Victoria, and present a sequential sampling plan for monitoring population densities. The distribution of Helicoverpa spp. eggs was highly contagious, as indicated by a Taylor's b-value of 1.59. This high level of contagion meant that relatively large sample sizes would need to be collected to obtain an estimate of population density. High-precision sampling plans generally necessitated impractical sample sizes, and thus the plan we present is a relatively low-precision level plan (SE/mean = 0.3). Nonetheless, this level of precision is considered adequate for most agronomic scenarios. The plan was validated using a statistical re-sampling approach. The level of precision achieved was generally close to the nominal level. Likewise, the number of samples collected generally showed little departure from the theoretically calculated minimum sample size.

Diet, physical activity and obesity statistics

This publication provides statistics on diet, physical activity and obesity as these relate to the incidence and prevalence of CVD.

Coronary heart disease statistics

This is the fourteenth edition of Coronary heart statistics produced by the British Heart Foundation.

It is divided into 13 chapters.

* The first two chapters on mortality and morbidity deal with demographic trends in CHD and related diseases of the circulatory system.
* Following a section on treatment of CHD there are chapters on the main modifiable risk factors for the disease: smoking, an unhealthy diet, lack of physical activity, a high alcohol consumption, poor psychosocial wellbeing, raised blood pressure, raised blood cholesterol, obesity and diabetes.
* The final chapter provides information about the economic costs of CHD.

The compendium was published by the British Heart Foundation in May 2006.

European cardiovascular disease statistics

This is the third edition of European cardiovascular disease statistics. The first edition was published in 2000 when the European Union (EU) consisted of 15 Member States. After enlargement in 2004 and then again in 2007, there are now 27 Member States. Much has changed in the last seven years, but cardiovascular disease (CVD) remains the main cause of death in the EU. The European cardiovascular disease statistics was the first publication to bring together all the available sources of information about the burden of CVD in Europe, including data on death and illness, treatment, the prevalence of behavioural risk factors for CVD (smoking, diet, physical inactivity and alcohol consumption), and the prevalence of medical conditions associated with CVD (raised cholesterol, raised blood pressure, overweight and obesity, and diabetes). It
has become an indispensable resource for anybody working on reducing the burden of CVD in Europe or in public health generally.

Stroke statistics

This publication is the latest edition of a series of statistical compendia and supplements that document the burden of cardiovascular disease in the United Kingdom. This series of publications, published by the British Heart Foundation, usually focuses on coronary heart disease, but Stroke Statistics is jointly published by the British Heart Foundation and The Stroke Association and focuses on the important and substantial burden of stroke in the United Kingdom.

Stroke Statistics is designed for policy makers, health professionals, medical researchers and anyone else with an interest in stroke or cardiovascular disease. It aims to provide the most recent statistics related to the burden of stroke and to document the geographic, social and ethnic inequalities in the experience of stroke.

Stroke Statistics is divided into five chapters. Chapter 1 documents trends and patterns in stroke mortality and premature mortality. Chapter 2 reports on the morbidity burden of stroke, both in terms of prevalence (the rate of people who have had a stroke in the past) and incidence (the rate of first ever strokes). Chapter 3 describes the burden of stroke on the National Health Service, in terms of drug therapy, hospitalisations and surgical procedures. Chapter 4 provides estimates of the prevalence of risk factors for stroke, broken down by age, sex, socioeconomic status and ethnicity. Details about Government targets to tackle the risk factor status of the population are also provided where available. Chapter 5 provides new estimates, calculated specifically for Stroke Statistics, of the economic cost of stroke to the National Health Service and to the United Kingdom economy.
