Objective:
To characterize the features of aged care users who died by suicide and examine the use of mental health services and psychopharmacotherapy in the year before death.
Design:Population-based, retrospective exploratory study
Setting and participants:Individuals who died while accessing or waiting for permanent residential aged care (PRAC) or home care packages in Australia between 2008 and 2017.
Measurements:Linked datasets describing aged care use, date and cause of death, health care use, medication use, and state-based hospital data collections.
Results:Of 532,507 people who died, 354 (0.07%) died by suicide, including 81 receiving a home care package (0.17% of all home care package deaths), 129 in PRAC (0.03% of all deaths in PRAC), and 144 approved for but awaiting care (0.23% of all deaths while awaiting care). Factors associated with death by suicide compared to death by another cause were male sex, having a mental health condition, not having dementia, less frailty, and a hospitalization for self-injury in the year before death. Among those who were awaiting care, being born outside Australia, living alone, and not having a carer were associated with death by suicide. Those who died by suicide more often accessed Government-subsidized mental health services in the year before their death than those who died by another cause.
Conclusions:Older men, those with diagnosed mental health conditions, those living alone and without an informal carer, and those hospitalized for self-injury are key targets for suicide prevention efforts.

Objective:
Obtaining objective, dietary exposure information from individuals is challenging because of the complexity of food consumption patterns and the limitations of self-reporting tools (e.g., FFQ and diet diaries). This hinders research efforts to associate intakes of specific foods or eating patterns with population health outcomes.
Design:Dietary exposure can be assessed by the measurement of food-derived chemicals in urine samples. We aimed to develop methodologies for urine collection that minimised impact on the day-to-day activities of participants but also yielded samples that were data-rich in terms of targeted biomarker measurements.
Setting:Urine collection methodologies were developed within home settings.
Participants:Different cohorts of free-living volunteers.
Results:Home collection of urine samples using vacuum transfer technology was deemed highly acceptable by volunteers. Statistical analysis of both metabolome and selected dietary exposure biomarkers in spot urine collected and stored using this method showed that they were compositionally similar to urine collected using a standard method with immediate sample freezing. Even without chemical preservatives, samples can be stored under different temperature regimes without any significant impact on the overall urine composition or concentration of forty-six exemplar dietary exposure biomarkers. Importantly, the samples could be posted directly to analytical facilities, without the need for refrigerated transport and involvement of clinical professionals.
Conclusions:This urine sampling methodology appears to be suitable for routine use and may provide a scalable, cost-effective means to collect urine samples and to assess diet in epidemiological studies.

Summary
This paper explores the design of biometric authentication in the context of a single user that has enrolled in multiple (distinct) authentication systems. The compromise of some subset of these systems will generally impact both the privacy of the user's biometric information and the security of the balance of the systems. In this work we consider how to design the systems jointly to minimize losses in privacy and security in the case of such compromise. It turns out that there is a tension between the two objectives, resulting in a privacy/security tradeoff.We introduce worst-case privacy and security measures, and consider the tradeoff between them, in the context of the “secure sketch” architecture. Secure sketch systems are based on error correction codes, and the considerations of joint design that we pose result in a novel code design problem. We first study the design problem algebraically and identify an equivalence with a type of subspace packing problem. While the packing problem fully characterizes the design space, it does not yield an explicit characterization. We then turn to a “fixed-basis” subspace of the general design space. We map a relaxed version of the fixed-basis design problem to a linear program which, after exploiting much symmetry, leads to an explicit tradeoff between security and privacy. While we show that fixed-basis designs are restrictive in terms of the achievable privacy/security tradeoffs, they have the advantage of being easily mapped to existing codes (e.g., low-density parity check codes), and thence to immediate deployment. Finally, we conjecture that the achievable privacy/security tradeoff of fixed-basis designs is characterized by an extremely simple analytic expression, one that matches our numerical results.
Introduction
The goal of an authentication system is to ensure that only legitimate individuals gain access to a secured resource or area. Increasingly popular are methods of authentication that use biometric data – unique information present in a person's physical attributes. An example of such a biometric system is a laptop-mounted fingerprint scanner, or an iris scanner at an airport.

A high intake of fruit and vegetables (FV) has been associated with reduced risk of a number of chronic diseases, including CVD. The aim of this review is to describe the potential use of biomarkers to assess FV intake. Traditional methods of assessing FV intake have limitations, and this is likely to impact on observed associations with disease outcomes and markers of disease risk. Nutritional biomarkers may offer a more objective and reliable method of assessing dietary FV intake. Some single blood biomarkers, such as plasma vitamin C and serum carotenoids, are well established as indicators of FV intake. Combining potential biomarkers of intake may more accurately predict overall FV intake within intervention studies than the use of any single biomarker. Another promising approach is metabolomic analysis of biological fluids using untargeted approaches to identify potential new biomarkers of FV intake. Using biomarkers to measure FV intake may improve the accuracy of dietary assessment.

Background:
Substance use disorders in older adults are expected to increase dramatically in the coming years. Given the increased susceptibility to cognitive deficits in older substance users (defined here as aged 50+ years due to the accelerated health decline observed in this population), it is important to consider the functional correlates of cognitive impairment in these older adults. This study details the cognitive status of older individuals attending outpatient drug and alcohol (D&A) treatment services and seeks to determine of the association of cognitive impairment to self-reported daily functioning.
Methods:Ninety nine clients aged 50 years or over attending outpatient D&A treatment services in Sydney, Australia participated. Cognition was assessed using the Addenbrooke's Cognitive Examination – Revised (ACE-R). Recent substance use (Australian Treatment Outcome Profile), physical and mental health (SF12, Geriatric Depression Scale), social isolation (Lubben Social Network Scale), and activities of daily living (Bayer ADL Scale) were also assessed.
Results:Nearly two-thirds of participants screened positive for cognitive impairment on the ACE-R; 41% and 65% of clients met the cut-off scores for mild cognitive impairment (MCI) and more severe cognitive impairment, respectively. Self-reported seizure history was a predictor of cognitive impairment.
Conclusions:The results suggest that cognitive impairment in this group is common. The assessment of cognitive status for this older group of patients should not only include the identification of cognitive impairment but also encompass mental health and social functioning. A greater understanding of the needs of this cohort will also enable better co-ordination with other health and welfare services tailored to this population.

Flight before the Wright brothers demonstrated their powered man–carrying flying machine was based on the philosophy of vehicles with high inherent stability combined with pilots whose only duty was to steer. This combination resulted in low controllability and poor manoeuvrability, with a strong response to the disturbances of rough air. The Wright brothers broke with the high–inherent–stability concept and combined inherently unstable aircraft with three–axis control operation by human pilots to achieve stable flight systems with good controllability and good manoeuvrability. This change from inherently stable to inherently unstable aircraft was the basic contribution made by the Wright brothers to start the age of flight.
In this paper, a picture of the state of flight control before the Wright brothers is built up from references to the literature. A similar picture is drawn for flight control developments after the Wright brothers, and the effect of their efforts on the progress of events is discussed. Plots with time as the independent variable and non–dimensional ordinates are used to illustrate the overall pattern of past developments in flight control and to indicate the course of future progress.

Background:
Medicinal substances have been identified as common agents of both unintentional and intentional poisoning among older people, including those with dementia. This study aims to compare the characteristics of poisoning resulting in hospitalization in older people with and without dementia and their clinical outcomes.
Methods:A retrospective cohort study involving an examination of poisoning by intent involving individuals aged 50+ years with and without dementia using linked hospitalization and mortality records during 2003–2012. Individuals who had dementia were identified from hospital diagnoses and unintentional and intentional poisoning was identified using external cause classifications. The epidemiological profile (i.e. individual and incident characteristics) of poisoning by intent and dementia status was compared, along with clinical outcomes of hospital length of stay (LOS), 28-day readmission and 30-day mortality.
Results:The hospitalization rate for unintentional and intentional poisoning for individuals with dementia was double and 1.5 times higher than the rates for individuals without dementia (69.5 and 31.6 per 100,000) and (56.4 and 32.5 per 1,00,000). The home was the most common location of poisoning. Unintentional poisoning was more likely to involve individuals residing in aged care facilities (OR 2.12; 95%CI 1.70–2.63) or health service facilities (OR 3.91; 95%CI 3.45–4.42). There were higher mortality rates and longer LOS for unintentional poisoning for individuals with dementia.
Conclusions:Clinicians need to be aware of the risks of poisoning for individuals with dementia and care is required in appropriate prescription, safe administration, and potential for self-harm with commonly used medications, such as anticholinesterase medications, antihypertensive drugs, and laxatives.

Although robust associations between dietary intake and population health are evident from conventional observational epidemiology, the outcomes of large-scale intervention studies testing the causality of those links have often proved inconclusive or have failed to demonstrate causality. This apparent conflict may be due to the well-recognised difficulty in measuring habitual food intake which may lead to confounding in observational epidemiology. Urine biomarkers indicative of exposure to specific foods offer information supplementary to the reliance on dietary intake self-assessment tools, such as FFQ, which are subject to individual bias. Biomarker discovery strategies using non-targeted metabolomics have been used recently to analyse urine from either short-term food intervention studies or from cohort studies in which participants consumed a freely-chosen diet. In the latter, the analysis of diet diary or FFQ information allowed classification of individuals in terms of the frequency of consumption of specific diet constituents. We review these approaches for biomarker discovery and illustrate both with particular reference to two studies carried out by the authors using approaches combining metabolite fingerprinting by MS with supervised multivariate data analysis. In both approaches, urine signals responsible for distinguishing between specific foods were identified and could be related to the chemical composition of the original foods. When using dietary data, both food distinctiveness and consumption frequency influenced whether differential dietary exposure could be discriminated adequately. We conclude that metabolomics methods for fingerprinting or profiling of overnight void urine, in particular, provide a robust strategy for dietary exposure biomarker-lead discovery.

The lack of robust measures of dietary exposure hinders a quantitative understanding of causal relationships between diet and health. Non-targeted metabolite fingerprinting was used to explore the relationships between citrus exposure in free-living human subjects, estimated by a FFQ, and the chemical content of urine. Volunteers (study 1, n 12; study 2, n 11) were classified into high-, medium- and low-frequency citrus consumption groups. Overnight and spot fasting urine samples were obtained after exposure to a standardised citrus-free evening meal. The urine samples were analysed by flow injection electrospray-ionisation MS followed by supervised multivariate data classification analysis to discover discriminatory features associated with the level of citrus exposure. Good separation of high and low citrus consumption classes was achieved. Deeper exploration of high-ranked explanatory mass signals revealed several correlated signals derived from proline betaine. Targeted analysis of the relative levels of proline betaine in both fasting and overnight urine samples demonstrated good correlation with FFQ exposure data. Acute exposure of volunteers to orange juice resulted in the appearance of proline betaine and several biotransformed products in postprandial urine samples. Biomarker validation showed sensitivities of 80·8–92·2 % and specificities of 74·2–94·1 % (false discovery rate-adjusted P values < 0·05) for elevated proline betaine in participants who reported high citrus consumption. Proline betaine biotransformation products displayed weaker quantitative relationships with habitual citrus exposure. Targeted screening for the presence of biotransformation products of hesperidin and narirutin, known to be abundant in oranges, revealed that they were relatively poor indicators of citrus exposure.

Summary
Chapter 11 describes how teams of wireless nodes can work together to improve the reliability of signaling. Due to the inherent uncertain, time-varying, and shared nature of the wireless environment (reflected in shadowing, small-scale fading, and interference), it is difficult to achieve extremely high reliability over a single wireless link even when advanced signal-processing techniques such as diversity and multiuser detection are employed. However, since wireless transmissions are inherently broadcast – overheard by all nodes within range – a natural approach to reliability is to develop cooperative techniques. Cooperative techniques exploit in parallel many helper nodes, called relays, to increase the diversity of the available wireless links. These techniques can yield large improvements in reliability and throughput as well as large decreases in energy consumption.
The chapter starts with an overview of various cooperative communications methods that can be employed depending on the level of channel state information (CSI) and device synchronization. The chapter then considers two techniques in more detail: relaying using virtual beamforming and rateless codes. In both cases, we start out with an analysis of a “fundamental building block” that consists of one source, a number of parallel relays, and one destination. In the virtual beamforming technique, the relays rebroadcast the source signal that they have decoded. Relays adjust their transmission amplitudes and phases to ensure that their transmissions interfere constructively, maximizing the destination's signal-to-noise ratio (SNR). In the rateless coding approach, the relays individually decode the source message.

The present report summarises a workshop convened by the UK Food Standards Agency (Agency) on 25 March 2010 to discuss the current Agency's funded research on the use of metabolomics technologies in human nutrition research. The objectives of this workshop were to review progress to date, to identify technical challenges and ways of overcoming them, and to discuss future research priorities and the application of metabolomics in public health nutrition research and surveys. Results from studies nearing completion showed that by using carefully designed dietary and sampling regimens, it is possible to identify novel biomarkers of food intake that could not have been predicted from current knowledge of food composition. These findings provide proof-of-principle that the metabolomics approach can be used to develop new putative biomarkers of dietary intake. The next steps will be to validate these putative biomarkers, to develop rapid and inexpensive assays for biomarkers of food intake of high public health relevance, and to test their utility in population cohort studies and dietary surveys.

In Wisniewski et al. (2010), paper I, we analyzed 15 years of spectroscopic and spectropolarimetric data from the Ritter and Pine Bluff Observatories of 2 Be stars, 60 Cygni and π Aquarii, when a transition from Be to B star occurred. Here we analyze the intrinsic polarization, where we observe loop-like structures caused by the rise and fall of the polarization Balmer Jump and continuum V-band polarization being mismatched temporaly with polarimetric outbursts. We also see polarization angle deviations from the mean, reported in paper I, which may be indicative of warps in the disk, blobs injected at an inclined orbit, or spiral density waves. We show our ongoing efforts to model time dependent behavior of the disk to constrain the phenomena, using 3D Monte Carlo radiative transfer codes.
