Discontinuous Galerkin (DG) methods provide a means of weakly enforcing the continuity of the unknown-field derivatives and have particular appeal in problems involving high-order derivatives. This feature has previously been successfully exploited (Comput. Methods Appl. Mech. Eng. 2008; 197:2901-2929) to develop a formulation of linear Kirchhoff-Love shells considering only the membrane and bending responses. In this proposed one-field method - the displacements are the only unknowns, while the displacement field is continuous, the continuity in the displacement derivative between two elements is weakly enforced by recourse to a DG formulation. It is the purpose of the present paper to extend this formulation to finite deformations and non-linear elastic behaviors. While the initial linear formulation was relying on the direct linear computation of the effective membrane stress and effective bending couple-stress from the displacement field at the mid-surface of the shell, the non-linear formulation considered implies the evaluation of the general stress tensor across the shell thickness, leading to a reformulation of the internal forces of the shell. Nevertheless, since the interface terms resulting from the discontinuous Galerkin method involve only the resultant couple-stress at the edges of the shells, the extension to non-linear deformations is straightforward.

Osteoarthritis (OA) is the most common form of arthritic disease, and it is a major cause of disability and impaired quality of life in the elderly. A hallmark of the disease is progressive degeneration of articular cartilage and subsequent joint space narrowing. However, OA is a complex disease not limited to cartilage degeneration, but involving also synovial membrane and subchondral bone, thereby presenting alternatives approaches for treatment. In this paper, we propose a short review of the recent advances in the understanding of the role played by subchondral bone in OA. [less ▲]

This paper considers the optimal design of mechatronic systems with configuration-dependent dynamics. An optimal mechatronic design requires that, among the structural and control parameters, an optimal choice has to be made with respect to design specifications in the different domains. Two main challenges are treated in this paper: the non-convex nature of the optimization problem and the difficulty in modeling serial machines with flexible components and their embedded controllers. The optimization problem is treated using the direct design strategy which considers simultaneously structural and control parameters as variables and adopts non-convex optimization algorithms. Linear time-invariant and gain-scheduling PID controllers are addressed. This methodology is exploited for the multi-objective optimization of a pick-and-place assembly robot with a gripper carried by a variable-length flexible beam. The resulting design tradeoffs between system accuracy and control efforts demonstrate the advantage of an integrated design approach for mechatronic systems with configuration-dependent dynamics. 2009 Elsevier Ltd.

Background. Recent studies suggest that implicit memory (especially perceptual implicit memory) persists during adequate general anaesthesia in adults. Studies in children, however, have failed to demonstrate implicit memory during general anaesthesia, possibly because of differences in methodological design. We therefore designed a prospective study with the aim of evaluating implicit memory in children undergoing general anaesthesia, using a perceptual memory test based on the mere exposure effect, previously tested in a control group. Methods. Twelve infrequent neutral words were played 12 times in a random sequence via headphones to 36 children aged 8–12 yr during elective or emergency surgery. The children were not premedicated, and general anaesthesia was maintained with isoflurane. The word presentation started immediately after the surgical incision. Within 36 h after the stimulus presentation, the memory was assessed by using a forced-choice preference judgement task. Time constraint and word deterioration with a low-pass filter were used to prevent the subjects from utilizing intentional retrieval. The implicit memory score was obtained by calculating the proportion of target words preferred, which was compared with the chance level (0.5). Results. The percentage of correct responses given by the children was comparable with the chance level. The memory score was mean (SD) 0.48 (0.16) (95% CI 0.43–0.53). Conclusions. The use of a perceptual implicit memory test based on the mere exposure procedure in children failed to reveal any evidence of implicit memory under general anaesthesia. [less ▲]

Side effects of steroid use have led to efforts to minimize their use in transplantation. Two corticosteroid-free regimens were compared with a triple immunosuppressive therapy. Data from the original intent-to-treat (ITT) population (153 tacrolimus/basiliximab [Tac/Bas], 151 tacrolimus/MMF [Tac/MMF], and 147 tacrolimus/MMF/steroids [control]) were analyzed in a 12-month follow-up. Percentage of graft survival were 92.8%, 95.4%, and 95.9% (KM estimates 89.9%, 95.3%, 95.9%), percentage of surviving patients were 98.7%, 98.0%, and 100% (KM estimates 95.9%, 92.8%, and 100%). During months 7-12, graft loss occurred in 3 Tac/Bas, 2 Tac/MMF, and zero control patients, patient deaths in 1 Tac/Bas, 2 Tac/MMF, and zero control, and biopsy-proven acute rejection episodes in 4 Tac/Bas, 3 Tac/MMF, and zero control. Mean serum creatinine at month 12 was 141.9 +/- 69.6 muM, 144.0 +/- 82.1 muM, and 134.5 +/- 71.2 muM (ns). New-onset insulin use in previously non-diabetic patients at month 12 was 1/138, 6/127, and 4/126. Patient and graft survival as well as renal function at 12 months were not different between patient groups, despite considerably higher rates of acute rejection occurring within the first six months after transplantation in both steroid-free patient groups. Tac/Bas therapy might offer benefits in terms of a trend for a more favorable cardiovascular risk profile. [less ▲]

This paper proposes a convenient and generally applicable diagnostic m-test for checking the distributional specification of parametric conditional heteroscedasticity models for financial data such as the customary Student t GARCH model. The proposed test is based on the moments of the probability integral transform of the innovations of the assumed model. Monte-Carlo evidence indicates that our test performs well both in terms of size and power. An empirical example illustrates the practical usefulness of the test and some of its possible extensions are outlined. [less ▲]

Since the first reports on the use of microwave irradiation to accelerate organic chemical transformations, a plethora of papers has been published in this field. In most examples, microwave heating has been shown to dramatically reduce reaction times, increase product yields, and enhance product purity by reducing unwanted side reactions compared with conventional heating methods. The present contribution aims at illustrating the advantages of this technology in homogeneous catalysis by ruthenium complexes and, when data are available, at comparing microwave-heated and conventionally heated experiments. Selected examples refer to olefin metathesis, isomerization reactions, 1,3-dipolar cycloadditions, atom transfer radical reactions, transfer hydrogenation reactions, and H/D exchange reactions.

Clinical research with the family has undergone relevant changes through time under an epistemological, theoretical, methodological and technical point of view. By rebuilding the main steps of such development, we will try to bring to the fore issues and problems that are at the centre of the present debate (researches untied from the theoretical model, mix-ups in logics between built-ups and levels of analysis, risks of over-interpretation on the basis of individual parameters) and the solutions put forward by those models that try and come back to a holistic vision of the family as research « object-subject ».

Aim: This study assesses the impact of serum carboxy-terminal collagen crosslinks (CTX) bone marker feedback (BMF) on adherence to ibandronate treatment in Asian postmenopausal women with osteoporosis. Methods: This was a 12-month (6-monthly phased), randomized, prospective, open-label, multi-center study conducted in 596 (of 628 enrolled) postmenopausal women with osteoporosis (£ 85 years old) who were naı¨ve, lapsed, or current bisphosphonate users. Patients were randomized into two arms: serum CTX BMF at 3 months versus no-BMF. Once-monthly 150 mg ibandronate tablet was administered for 12 months and adherence to therapy was assessed at 6 and 12 months. In addition, patient satisfaction and safety of ibandronate treatment were also assessed. Results: Serum CTX BMF at 3 months showed no impact on adherence. The proportions of adherent patients were comparable in the BMF versus no-BMF arms (92.6% vs. 96.0%, P = 0.16); overall, serum CTX levels were similar for adherent and non-adherent patients. However, BMF patients felt more informed about their osteoporosis (P < 0.001) and more satisfied (P < 0.01) than no-BMF patients. Conclusions: The Asian postmenopausal osteoporosis patients in this study had a high adherence rate to once-monthly ibandronate therapy. Use of serum CTX BMF had no further impact on increasing adherence, but increased treatment satisfaction. [less ▲]
