A class of low-complexity compressive sensing-based direction-of-arrival (DOA) estimation methods for wideband co-prime arrays is proposed. It is based on a recently proposed narrowband estimation method, where a virtual array model is generated by directly vectorizing the covariance matrix and then using a sparse signal recovery method to obtain the(More)
OBJECTIVES To examine predictors for 5-year survival in elderly stroke patients. MATERIALS AND METHODS Prospective cohort study of 186 consecutive acute stroke patients aged ≥65 years admitted to Bankstown-Lidcombe Hospital, Australia 03/2002 to 03/2003. All subjects were followed up in 2007/8, at 5 years post-stroke, for outcome measures. Logistic(More)
STUDY OBJECTIVE - Nested case-control study aimed to assess the quality of life of community dwelling participants aged 65 years or over with newly diagnosed Essential Tremor (ET). METHODS AND RESULTS - Thirty-two participants with newly diagnosed ET and 32 age and gender matched controls were administered the Rand-SF36 quality of life questionnaire.(More)
OBJECTIVES To compare hospital length of stay (LOS) and outcome after stroke between patients in a stroke unit offering combined acute and rehabilitation services and patients treated elsewhere in New South Wales. DESIGN Retrospective audit of two hospital databases (Diagnosis-Related Groups [DRG] database and Australian National Subacute Non-Acute(More)
Longitudinal data sets from certain fields of biomedical research often consist of several variables repeatedly measured on each subject yielding a large number of observations. This characteristic complicates the use of traditional longitudinal modelling strategies, which were primarily developed for studies with a relatively small number of repeated(More)
OBJECTIVE To investigate risk factors, stroke pattern and outcome in stroke patients with cancer. METHODS A retrospective review of all stroke patients with cancer (n = 69) admitted to Bankstown-Lidcombe Hospital, Sydney, Australia, between January 1999 and December 2004 was conducted, and comparison made to age- and gender-matched non-cancer stroke(More)
Internet of Things (IoT) is an emerging network which is designed to combine sensor networks and other things with the Internet. IoT includes numerous things, each of which is allocated an unique identity (UID). UID management plays an very important role in guaranteeing the efficiency of IoT system. Since IoT is a task-oriented network, there must be a(More)
A novel wideband direction-of-arrival (DOA) estimation method is proposed for co-prime arrays. After decomposing the wideband signals into different frequencies/subbands through a discrete Fourier transform or, more generally, a filter bank system, the increased degrees of freedom provided by co-prime arrays are fully exploited with a group sparsity based(More)
