Onychomycosis is a frequent disorder that represents the most prevalent fungal infection, particularly among older individuals. Diverse fungi of the dermatophyte, non-dermatophyte mold and yeast families have been reported to be responsible for onychomycosis. The output from the pharmaceutical industry of new antifungals to treat onychomycosis has been limited over the last decade. Present treatment options include both oral and topical drugs, with oral therapies giving better outcomes. However, neither of these treatment options provides high cure rates that are durable. At present, azoles and allylamines are keeping the pivotal roles. New derivatives with a favorable risk-benefit ratio and new formulations of older azoles seem to be promising. Thus, ongoing drug development activities have focused on novel delivery technologies to facilitate incorporation of existing antifungal drugs inside the nail plate and the discovery of new active antifungals.

At the microscale, classical bearings such as ball bearings, sliding bearings and other pivots may be difficult to manufacture. Among all possible solutions to replace them, the notch hinge seems to be very attractive through its many advantages. The major limitation is on the rotation angle. This paper presents a new simplified analytical model for the prediction of the maximum angular displacement and the angular stiffness of a notch hinge. To validate our model, an experimental set-up has been developed. Finally, the results are compared to other theories. [less ▲]

The inhomogeneous mineral content and its topographical distribution on a microscopic scale are major determinants of the mechanical quality of trabecular bone. The kinetics of bone tissue deposition and resorption together with the kinetics of the mineralization process determine the distribution of mineral in the tissue. The heterogeneity of the mineral content is described by the well-established bone mineralization density distribution (BMDD), which is experimentally accessible, e.g., using quantitative electron backscattering imaging (qBEI). In the present work, we demonstrate that the shape of the BMDD histogram of trabecular bone reflects directly the mineralization kinetics. Based on the experimental BMDD data of trabecular bone from healthy human adults and using a mathematical model for the remodeling and the mineralization process, the following main results were obtained. The peaked BMDD reflects necessarily a two-phase mineralization process with a fast primary phase and a slow secondary phase where the corresponding time constants differ three orders of magnitude. The obtained mineralization law, which describes the increase in the mineral content in a bone packet as a function of time, provides information not only about the initial mineralization surge, but also about the slow increase afterwards on the time scale of years. In addition to the mineralization kinetics the turnover rate of the remodeling process has a strong influence on the peak position and the shape of the BMDD. The described theoretical framework opens new possibilities for an analysis of experimentally measured BMDDs with respect to changes caused by diseases or treatments. It a] lows addressing whether changes in the BMDD have to be attributed to a variation in the turnover rate which consequently affects the density distribution or to a primary disorder in the mineralization process most likely reflecting alterations of the organic matrix. This is of important clinical interest because it helps to find therapeutic approaches directly targeting the primary etiological defects to correct the patients' BMDD towards normal BMDD.

Accurate models of hydraulic motors and their interaction with flexible structures are needed to design motion control and vibration suppression schemes for hydraulically actuated flexible robots. The modeller of such a system faces significant challenges including capturing the dynamics of the actuator, integrating the actuator model into the system model, incorporating distributed parameter elements into the system model, determining any unknown model parameters, and creating a model that is useful for control design. This paper presents a model that overcomes all of these challenges. A transfer matrix model of a hydraulic actuator interacting with a flexible robot is developed. This model is integrated into a system model for a flexible robot. The model captures the interaction between the actuator and the structure and has been experimentally validated. [less ▲]

This paper surveys the growing literature on developing countries’ infrastructure performance measured through frontier analysis techniques. The focus is generally on assessments of operators’ efficiency and productivity growth as part of benchmarking exercises. Two broad types of benchmarks are identified in the literature. The first is based on cross-country or cross regional performance comparisons, the second compares performance before and after reforms, including privatization. These benchmarks are often used to assess the impact of potential or actual policy reforms in specific countries. In a growing number of instances, they are also being conducted in the context of tariff revisions to assess the efficiency gains that can be shared with users as part of these revisions. The main policy conclusions are that there is a difference in the performance effect of key reforms, in particular privatization, between the transport sector and the utilities sector but that generally incentive based regulation delivers efficiency in both sectors The main technical conclusion is that even if in developing economies data problems are constraining, these constraints are not as binding as often argued.

Uncertainty is one of the contingency factors examined by previous studies on management control systems design. However, its role remains unclear. This paper presents the results of an empirical study, which shows that perceived uncertainty more intervenes to explain the of informal management control mechanisms and the interactive use of formal management control systems than to explain the nature of the latter.

This paper presents the experimental and numerical tests made on the Titanium based alloy Ti6A14V to identify its yield locus and the hardening behaviour. A bi-axial experimental equipment has been used to perform cyclic shear tests, simple shear tests and successive simple shear tests and plane-strain tests. Coupled with classical tensile tests, these tests enable to identify the yield locus and the hardening model. Teodosiu and Hu’s hardening law and isotropic Swift type hardening and kinematic Armstrong Frederick hardening models have been investigated. [less ▲]

Principal Component Analysis (PCA) is a classical technique in statistical data analysis, feature extraction and data reduction, aiming at explaining observed signals as a linear combination of orthogonal principal components. Independent Component Analysis (ICA) is a technique of array processing and data analysis, aiming at recovering unobserved signals or ‘sources’ from observed mixtures, exploiting only the assumption of mutual independence between the signals. The separation of the sources by ICA has great potential in applications such as the separation of sound signals (like voices mixed in simultaneous multiple records, for example), in telecommunication or in the treatment of medical signals. However, ICA is not yet often used by statisticians. In this paper, we shall present ICA in a statistical framework and compare this method with PCA for electroencephalograms (EEG) analysis.We shall see that ICA provides a more useful data representation than PCA, for instance, for the representation of a particular characteristic of the EEG named event-related potential (ERP).
