An efficient adaptive optics (AO) simulation code was developed, which enables first-order simulations of extremely high-order systems. The Monte-Carlo-type code employs a sparse conjugate gradient algorithm for wavefront reconstruction, and a separation of spatial frequencies into two domains to economize on the number crunching. High-order multi-conjugate adaptive optics (MCAO) systems are there

BACKGROUND: In patients with atrial septal defect (ASD) the P-wave is prolonged as a marker of delayed atrial conduction which is associated with atrial fibrillation. The study aim was to analyse the impact of ASD closure in adults on P-wave duration and morphology by means of signal-averaged P-waves (PSA-ECG) and to investigate potential mechano-electrical interactions. METHODS: PSA-ECG was obtai

Calls for more robust societal emergency management capacities have grown shriller as the range of societal vulnerabilities widens. The development of workable plans is recognised as one means to increase capacity. However, scepticism persists that plans serve any significant function in guiding organisational emergency management. Plans nevertheless remain a de facto requirement for most organisa

These are among the most ancien

Abstract. Under the influence of U.S. government regulations, enforcement of anti-bribery laws and embarrassing corruption scandals, major global corporations have realized that unethical conduct may affect not only their reputations but their profits. This development has given rise to a new position within the traditional management team: the ethics and compliance officer (who differs from the e

Purpose. This research describes and evaluates a liposuction surgery and multidisciplinary rehabilitation approach for advanced lymphedema of the upper and lower extremties. Methods. A prospective clinical study was conducted at an Advanced Lymphedema Assessment Clinic (ALAC) comprised of specialists in plastic surgery, rehabilitation, imaging, oncology, and allied health, at Macquarie University,

BACKGROUND: Osteoarthritis of the hands is a prevalent musculoskeletal disease with a considerable effect on patients' lives, but knowledge and research results in the field of hand osteoarthritis are limited. Therefore, the Disease Characteristics in Hand OA (DICHOA) initiative was founded in early 2005 with the aim of addressing key issues and facilitating research into hand osteoarthritis. OBJE

The relationship between a percept-genetic measurement of creativity and other tests of creativity was investigated. The participants were elementary school children. The relation between self-image and three different creativity measures was also studied. A creative fluency test, a questionnaire about creative activities and a percept-genetic creativity test were used. A self-image inventory meas

To investigate defense mechanisms, repressors (n= 14), highly anxious (n = 37) and low anxious (n = 7) groups were tested with the Meta Contrast Technique (Smith, Johnson, Almgren & Johanson, 2001). The division into repressors and anxiety groups was made on a larger group (N = 140), which was also investigated with respect to experienced access to preconscious processes, here operationalized

The acoustic emission that is detectable in the forming of complex thin part plates contains information about the quality of the pressed plates. The information can be used as process control and to filter out advanced thin plates with defects such as cracks. The article describes the results obtained in a try-out pressing process in special developed punch-die pairs with different pressing

Designs for Extremely Large Telescopes (ELTs) are quite well advanced,but the requirements of instruments have had limited impact. Sinceprovision of a suitable environment for instruments is a critical aspectof all telescopes, we outline some well-known and some less-appreciatedchallenges of designing instruments for ELTs. A wide-field spectrometer(WFSPEC) with ~10 arcmin field-of-view, probably w

We present an estimate for the convergence rate of the Dirichlet-Neumann iteration for the discretized unsteady transmission problem. Specifically, we consider the coupling of two heat equations on two identical squared domains. The Laplacian is discretized by second order central finite differences and the implicit Euler method is used for the time discretization. For the semidiscrete case, Hensh

The goal of the paper is to present a distributed scheme to resolving a single path routing problem in multidomain networks. The global problem is formulated as a mixed-integer program (MIP) and approached by means of branch-and-price (B&P). Problems associated with a B&P tree nodes are decomposed using the Dantzig-Wolfe method to a set of domain subproblems coordinated by a single master

This paper studies contextual effects on fertility at the onset of fertility decline in Sweden. We argue that the community exerts an influence on fertility when individuals belonging to a certain community are more similar to one another (within-area) in their reproductive behaviour than individuals living in another community (between-area). Our hypotheses are that community had a strong influen

PUFA from oil extracted from Nile perch viscera were enriched by selective enzymatic esterification of the free fatty acids (FFA) or by hydrolysis of ethyl esters of the fatty acids from the oil (FA-EE). Quantitative analysis was performed using RP-HPLC coupled to an evaporative light scattering detector (RP-HPLC-ELSD). The lipase from Thermomyces lanuginosus discriminated against docosahexaenoic
