The results of a preliminary analysis of BD +03 deg 740 are presented. The analysis was based on the blue spectrum which was obtained with an exposure time of 40 min, giving a good S/N ratio for this 9.8-mag star. Graphs are presented which reveal the extreme weakness of the metal lines in the spectrum. The analysis of BD +03 deg 740, which is the most metal-poor dwarf in which s element abundances have been determined, confirms the presence of secondary elements in the atmospheres of the extreme halo dwarfs.

The present study investigated how benevolent (BS) and hostile sexism (HS) shift women’s self-construal and autobiographical memory. Belgian undergraduates (only women, N=45, mean age=21.8) were confronted either by BS, HS or neutral comments in the context of a job interview. After performing a cognitive task, participants reported the intrusive thoughts that came to their mind during the task. Later, autobiographical memory for self-incompetence was assessed. Performance response latencies were slower after BS than HS. Also, BS generated more disturbing mental intrusions related to the idea of being incompetent than HS. Autobiographical memory similarly indicated greater access for incompetence after BS. Although HS was more aggressive in tone, it did not shift women’s self-construal and autobiographical memories toward incompetence. [less ▲]

To trim or not to trim beaks? It is always a good time to raise this difficult question. Indeed, since the release of the Brambell Committee report1 on welfare in the UK in 1965, discussion on the welfare of beak-trimmed birds has continued unabated. The aim of this new book (with its 15 contributors) is not, of course, to close the debate but merely to consolidate the huge amount of scientific information available on methods welfare and alternatives to beak-trimming. In the Preface, it is stated that the book will be of interest to welfare groups, policy makers, scientists, industry leaders and students of poultry science who wish to acquaint themselves with the welfare issues associated with beak-trimming and the potential solutions for reducing the need to beak-trim poultry. This goal is achieved to the extent that most of the information (although sometimes rather concisely) is presented in the eight chapters of this 174 page book. The first chapter describes the methods and reasons for beak-trimming. Chapter 2 raises the ethical question of beak-trimming and gives some of the pros and cons of the arguments. Pain and nerve injuries induced by beak-trimming are presented in Chapters 3–5 and the production responses (improved liveability, plumage quality and feed efficiency during egg laying) of beak-trimmed birds are assessed in Chapter 6 with bird health and handling issues associated with beak-trimming in Chapter 7. The last chapter is devoted to alternatives to beak-trimming. It includes environmental enrichment methods; a consideration of the genetics of feather pecking and cannibalism; dietary recommendations to reduce cannibalism in chickens and laying hens; manipulation of light intensities and colour to modify behaviour; management of body weight; application of abrasive strips in the feed trough to blunt the tips of the beaks of laying hens and the use of fitted devices and stock wound spray in injured birds to prevent further pecking. Among all these alternatives, the genetic solution might well prove to be the most sustainable, efficacious and cost effective. Overall, however, throughout the book this reviewer had the feeling, rightly or wrongly, that it was mostly written by opponents of beak-trimming and that arguments of the defence were sometimes omitted.

Positioning is a fundamental issue in mobile robot applications, and it can be achieved in multiple ways. Among these methods, triangulation based on angle measurements is widely used, robust, accurate, and flexible. This paper presents BeAMS, a new active beacon-based angle measurement system used for mobile robot positioning. BeAMS introduces several major innovations. One innovation is the use of a unique unsynchronized channel with On-Off Keying modulated infrared signals to measure angles and to identify the beacons. We also introduce a new mechanism to measure angles: our system detects a beacon when it enters and leaves an angular window. We show that the estimator resulting from the center of this angular window provides an unbiased estimate of the beacon angle. A theoretical framework for a thorough performance analysis of BeAMS is provided. We establish the upper bound of the variance and validate this bound through experiments and simulations; the overall error measure of BeAMS is lower than 0.24 deg for an acquisition rate of 10 Hz. In conclusion, BeAMS is a low power, flexible, and robust solution for angle measurement, and a reliable component for robot positioning. [less ▲]

Introduction: Functional time-varying cardiac elastances (FTVE) contain a rich amount of information about the specific cardiac state of a patient. However, a FTVE waveform is very invasive to directly measure, and is thus currently not used in clinical practice. This paper presents a method for the estimation of a patient specific FTVE, using only metrics that are currently available in a clinical setting. Method: Correlations are defined between invasively measured FTVE waveforms and the aortic and pulmonary artery pressures from 2 cohorts of porcine subjects, 1 induced with pulmonary embolism, the other with septic shock. These correlations are then used to estimate the FTVE waveform based on the individual aortic and pulmonary artery pressure waveforms, using the “other” dysfunction’s correlations as a cross validation. Results: The cross validation resulted in 1.26% and 2.51% median errors for the left and right FTVE respectively on pulmonary embolism, while the septic shock cohort had 2.54% and 2.90% median errors. Conclusions: The presented method accurately and reliably estimated a patient specific FTVE, with no added risk to the patient. The cross validation shows that the method is not dependent on dysfunction and thus has the potential for generalisation beyond pulmonary embolism and septic shock. [less ▲]
