#1
David Ebner, Martin Bauch, Theodoros Dimopoulos
Transparent electrodes based on an ultrathin Cu layer, embedded between two dielectrics, are optimized by simulations and experiments. Different dielectrics are screened in transfer matrix simulations for maximizing the broad-band transmittance. Based on this, sputtered electrodes were developed with the Cu embedded between TiO<sub>X</sub>-coated glass or PET substrate and an Al-doped ZnO (AZO) top layer. It is found that, for ultrathin Cu layers, increased sputter power fosters island coalescence, leading to superior optical and electrical performance compared to previously reported Cu-based electrodes...

Minimax optimization, which is actively involved in numerous robust design problems, aims at pursuing the solutions with best worst-case performances. Although considerable research has been devoted to the development of minimax optimization algorithms, there still exist several fundamental limitations for existing approaches, e.g., restriction on problem types, excessively high computational cost, and low optimization efficiency. To address these issues, a minimax differential evolution algorithm is proposed in this paper...

BACKGROUND: Chronic pain is defined as pain lasting beyond normal tissue healing time, generally taken to be 12 weeks. It contributes to disability, anxiety, depression, sleep disturbances, poor quality of life, and healthcare costs. Chronic pain has a weighted mean prevalence in adults of 20%.For many years, the treatment choice for chronic pain included recommendations for rest and inactivity. However, exercise may have specific benefits in reducing the severity of chronic pain, as well as more general benefits associated with improved overall physical and mental health, and physical functioning...

Multilayer architectures in water purification membranes enable increased water throughput, high filter efficiency, and high molecular loading capacity. However, the preparation of membranes with well-organized multilayer structures, starting from the nanoscale to maximize filtration efficiency, remains a challenge. We report a complete strategy to fully realize a novel biomaterial-based multilayer nanoporous membrane via the integration of computational simulation and experimental fabrication. Our comparative computational simulations, based on coarse-grained models of protein nanofibrils and mineral plates, reveal that the multilayer structure can only form with weak interactions between nanofibrils and mineral plates...

EDITORIAL
M Danta, N Ghinea
The economic impact of medications is significant, with many countries unable to afford the essential medicines listed by the WHO. Generic medications are one strategy to address this issue. Generic medications are similar to but not the same as originator medications. They have a significant cost advantage because they do not require the background research and development studies to support registration. Consequently, they are gaining increased market share in both the developed and developing world. Many new medications are now licensed to generic manufacturers in the developing world...

In restorative treatment using fixed dental prostheses, dentists should select appropriate restoration material among various types of dental materials. The strength, marginal fit, esthetics, wear resistance, biocompatibility, and cost are important factors in the choice of restoration materials. The present case showed a surface stain on a monolithic zirconia restoration that was due to wear between the monolithic zirconia restoration and the base metal alloy restoration. This phenomenon was confirmed by surface roughness measurement and electron probe micro-analysis...

BACKGROUND: The use of direct oral anticoagulants (DOACs) is restricted by the limitations of clinical trials guiding therapy for patients with renal impairment, as many of these trials excluded patients with severe renal impairment. There are currently four agents available: dabigatran, rivaroxaban, apixaban, and edoxaban. The purpose of this review was to 1) describe current recommended dosing for each DOAC and published postmarketing data, including case reports, on the use of these agents in the renally impaired; and 2) discuss patient adherence and satisfaction and the cost of these agents...

Geophysical methods are used increasingly for characterization and monitoring at remediation sites in fractured-rock aquifers. The complex heterogeneity of fractured rock poses enormous challenges to groundwater remediation professionals, and new methods are needed to cost-effectively infer fracture and fracture-zone locations, orientations and properties, and to develop conceptual site models for flow and transport. Despite the potential of geophysical methods to "see" between boreholes, two issues have impeded the adoption of geophysical methods by remediation professionals...

S Kühl, B Gassler, A Spiller
Pasture-raised milk is gaining in importance in some European countries and in the United States. The production of pasture-raised milk is linked to higher costs, as the milk is normally collected and processed separately from conventional barn milk. This could hinder the production of sustainable milk products. We discuss alternative labeling strategies that allow the mixing of pasture-raised (sustainable) and conventional milk to reduce costs and break free from the current niche market. The lower price would allow for more pasture-raised milk to be produced and enter the mainstream market...

AIM OF THE STUDY: To report the current activity of intestinal transplantation in Europe (EU) and Unites States of America (USA), underlining outcomes in the last 5 years and discussing possible trends. PATIENTS AND METHODS: Data review of results was performed through analysis of ITR and UNOS registries, Eurotransplant and newsletter transplant reports, congress abstracts, international published literature, personal communications and hospital web sites. RESULTS: The absence in Europe of a sole organization collecting donors and the presence of many low-volume centers (less than 5 cases/year) makes the difference with USA: in the last 5 years (2010-2014), 222 intestinal/multivisceral transplants have been performed in EU countries (most of them in the UK), while in USA, the number of transplants achieved 634 procedures in the same period of time...

BACKGROUND AND AIMS: Familial hypercholesterolaemia (FH) is a genetic disorder associated with significantly elevated plasma low-density lipoprotein cholesterol (LDL-C) and premature coronary heart disease (CHD). Optimal management of FH relies on early identification and treatment with statins alone or in combination with other lipid-lowering therapies. A lack of awareness of FH and its manifestations among primary care physicians and specialists has led to many individuals being misdiagnosed in the early stages of the disease, further increasing the risk of CHD and requiring much more intensive lipid-lowering strategies...
