Influence of surface roughening on indentation behavior of thin copper coatings using a molecular dynamics approach

The structure of interest consists of a nanometer thin copper coating, resting on an infinitely stiff substrate and subjected to nanoindentation by a rigid diamond indenter. The elastic and plastic properties of the coating are investigated for different surface roughening position of attack by the indenter using molecular dynamics. The force-displacement curves, the lattice disorders and the stre

Antenna Current Optimization using MATLAB and CVX

Antenna current optimization is a tool that offers many possibilities in antenna technology. Optimal currents are determined in the antenna design region and used for physical understanding, as a priori estimates of the possibilities todesign antennas, physical bounds and as figures of merits for antenna designs. Antenna current optimization is particularly useful for small antennas and antennas t

Prognostic instrument for survival outcome in melanoma patients : based on data from the population-based Swedish Melanoma Register

BACKGROUND: Several major analyses have identified a consistent set of independent risk factors for cutaneous malignant melanoma (CMM). A few prognostic models have been presented but some are based on a limited number of patients and others are based on selected groups of patients referred to major institutions. No nationwide population-based prognostic instrument for survival of CMM has been pre

Novel Approach to Controlled Surface Modification in Textile Via Magnetic Cross- Linked Enzyme Aggregates (Clea)

In this proceeding, architecting novel magnetic Cross-Linked-Enzyme-Aggregates (CLEA)nanoparticles to effectively and controllably modify textile surfaces without damaging the fabric itself, will bediscussed. The efficiency is due to exponentially increased surface concentration of biocatalyst and to thechoice of aggregate size which controls the penetration depth and hence preventing the fabric d

A Nested Case-Control Study of Metabolically Defined Body Size Phenotypes and Risk of Colorectal Cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC)

BACKGROUND: Obesity is positively associated with colorectal cancer. Recently, body size subtypes categorised by the prevalence of hyperinsulinaemia have been defined, and metabolically healthy overweight/obese individuals (without hyperinsulinaemia) have been suggested to be at lower risk of cardiovascular disease than their metabolically unhealthy (hyperinsulinaemic) overweight/obese counterpart

Design of a compact varied-line space grating monochromator for enhanced flux at MAXLAB

For soft x-ray fluorescence spectroscopy with selective energy excitation, it is desirable to have maximum flux at moderate resolution. A plane grating monochromator with varied line spacing can be used in the convergent beam of an ellipsoidal focusing mirror to provide moderate resolution with a large collection angle and minimum number of reflecting surfaces. We determine the design parameters f

Observation of a low-binding-energy peak in the 2p core-level photoemission from oxidized Al(111)

High-resolution photoemission studies of oxidation of the Al(111) surface have been performed. The appearance of a component at lower binding energy than the metallic bulk Al emission in the Al 2p spectrum at oxygen exposures above ∼50 langmuir (1 L = 10-6 Torr s) is argued to be due to Al atoms which do not bond directly to oxygen atoms at the oxide-metal interface. Low-energy electron diffractio

The stock-flow model of spatial data infrastructure development refined by fuzzy logic

The system dynamics technique has been demonstrated to be a proper method by which to model and simulate the development of spatial data infrastructures (SDI). An SDI is a collaborative effort to manage and share spatial data at different political and administrative levels. It is comprised of various dynamically interacting quantitative and qualitative (linguistic) variables. To incorporate lingu

How to understand and handle divergent views on the need for leadership interventions: a social constructionist approach

This paper addresses the challenge of how to understand and handle divergent views on the need for leadership interventions between managers and subordinates. Recent popular discourses of leadership, such as the authentic leadership perspective, privileges the potential leader himself or herself as the origin of leadership. This perspective thereby neglects the view of the followers and the essent

Angiotensin-Converting Enzyme Inhibitors and Angiotensin Receptor Blockers in Myocardial Infarction Patients With Renal Dysfunction

BACKGROUND: There is no consensus whether angiotensin-converting enzyme inhibitor (ACEI) and angiotensin receptor blocker (ARB) should be used for secondary prevention in all or in only high-risk patients after an acute myocardial infarction (AMI).OBJECTIVES: This study sought to investigate whether ACEI/ARB treatment after AMI is associated with better outcomes across different risk profiles, inc

The long-term health benefits of receiving treatment from qualified midwives at birth

Socio-economic differences in health and mortality are substantial and increasing today in many developed countries. The sources of these differences remain debated. There is an expanding literature showing that early-life conditions are linked to health in adulthood and old age. However, our knowledge about whether beneficial treatments in early life influence later health is still limited. Using

Polarisation-dependent X-ray absorption in high- and low-Tc Bi2Sr2Can-1CunO4+2n superconductors

Taking advantage of the linear polarisation of synchrotron radiation, the polarisation dependence of the O K and Cu L3 X-ray absorption edges has been compared for in situ cleaved Bi2Sr2CaCu2O8 and Bi2Sr2CuO6 single crystals. The X-ray absorption spectra were measured by means of total electron yield detection. The spectra show for both crystals that the lowest unoccupied Cu 3d and O 2p orbitals a

Industry attitudes towards ecodesign standards for improved resource efficiency

Current European regulations on producer responsibility provide limited incentives for ecodesign practices among manufacturers. Additional incentives for 'design for resource efficiency' and 'design for recycling' could be provided through mandatory design standards set under the Ecodesign Directive. While European manufacturers have become increasingly positive towards eco-design standards for en

Advancing sustainable solutions : An interdisciplinary and collaborative research agenda

Sustainable solutions are needed to drive a profound industrial and societal transformation towards a sustainable, low-carbon, resilient, equitable and prosperous future. This Special Volume of the Journal of Cleaner Production addresses possibilities and drivers for change by focusing on strategies for sustainable solutions with the underlying purpose of defining an interdisciplinary and collabor

Glucose-dependent insulinotropic polypeptide (GIP) and GIP receptor (GIPR) genes : An association analysis of polymorphisms and bone in young and elderly women

Introduction: The gastro-intestinal hormone glucose-dependent insulinotropic polypeptide (GIP) potentiates glucose-induced insulin secretion, with bone anabolic effects through GIP receptor (GIPR) in animal models. We explore its potential in humans by analyzing association between polymorphisms (SNPs) in the GIP and GIPR genes with bone phenotypes in young and elderly women. Methods: Association

Mitotic History Reveals Distinct Stem Cell Populations and Their Contributions to Hematopoiesis

Homeostasis of short-lived blood cells is dependent on rapid proliferation of immature precursors. Using a conditional histone 2B-mCherry-labeling mouse model, we characterize hematopoietic stem cell (HSC) and progenitor proliferation dynamics in steady state and following several types of induced stress. HSC proliferation following HSC transplantation into lethally irradiated mice is fundamentall
