Objective: Drug eluting stents (DES) might improve the results of stenting in the femoropopliteal (FP) segment, but randomized data between DES and BMS in the treatment of patients with chronic limb threatening ischemia (CLTI) is lacking. The aim of this study was to perform a randomized comparison, between DES and bare metal stent (BMS) implantation in a subgroup of CLTI patients with lesions in

The large variations of polyp sizes and shapes and the close resemblances of polyps to their surroundings call for features with long-range information in rich scales and strong discrimination. This article proposes two parallel structured modules for building those features. One is the Transformer Inception module (TI) which applies Transformers with different reception fields in parallel to inpu

Den undersökning och intervjubaserade mixed metods-forskningen som presenteras i denna sammanläggningsavhandling utforskar hur flygtekniker i Sverige, Norge och Portugal upplever att arbeta under den vertikala kedjan av hård och mjuk lagstiftning som utgör Europeiska Unionens reglering av denna sektor. Genom att fokusera på händelserapportering och certifiering av att flygplan kan tas i drift, somThe survey and interview-based mixed methods research presented in this compilation dissertation explores how licensed aircraft maintenance engineers in Sweden, Norway and Portugal experience working under the vertical chain of hard and soft law that makes up the European Union regulation of this sector. By focusing on occurrence reporting and the certification and release of aircraft into service

Understanding various aspects of ferroelectricity in hafnia-based nanomaterials is of vital importance for the development of future nonvolatile memory and logic devices. Here, the unconventional and weak electromechanical response of epitaxial La0.67Sr0.33MnO3/Hf0.5Zr0.5O2/La0.67Sr0.33MnO3 ferroelectric capacitors is investigated, via the sensitivity offered by nanobeam X-ray diffraction experime

The advent and popularity of shared electric scooters in many urban areas worldwide offer new opportunities and challenges to be addressed by the research community, especially as far as safety and accessibility issues are concerned. This paper proposes a methodology, based on geofencing technology (i.e., virtual geographic boundaries) to define in which urban areas the speed of shared electric sc

In this work, we use the measurement technique of high-speed Diffuse Back Illumination Extinction Imaging (DBI-EI) to obtain quantitative information in the form of projected liquid volume (PLV) in a highly transient GDI process. For the DBI-EI setup we use a LED-Panel as the light source, which fulfills diffuse back illumination extinction imaging criteria. Measurements were carried out in a cons

An accurate blood test for Alzheimer's disease that is sensitive to preclinical proteinopathy and cognitive decline has clear implications for early detection and secondary prevention. We assessed the performance of plasma phosphorylated tau 217 (pTau217) against brain PET markers of amyloid [[11C]-labelled Pittsburgh compound B (PiB)] and tau ([18F]MK-6240) and its utility for predicting longitud

In this note we study how the share of workers in a corporation located in a high gender wage gap country impacts the wage gap in their home country operations. Our findings support the hypothesis that firms with strong intra-firm linkages to a high gender wage gap country also display a relatively large gender wage gap at home.

There are plenty of books and articles on research methods, but few discuss the nature and purpose of method sections in academic journals. Based on interviews with critical and interpretivist researchers, this short paper examines the nature and purpose of method sections in management and organization studies. We show how researchers make sense of, and struggle with, positivist expectations abou

In business discourse, the leader is often portrayed as the one who changes the current order. Leaders stand above the organization, and from that elevated position they can bring about the necessary change that offers a way out of whatever crisis afflicts the business. In this paper, I consider the paradoxical fact that leaders, in our popular understanding at least, do not use orders when creati

A model is presented for studying the energy used by the braking system in heavy vehicles. The aim is to keep the model as simple as possible, while retaining reasonable fidelity for the problem at hand. All actuators are thus created as ideal, i.e. no losses, then simple dissipative loads are added where applicable in order to capture their effects from a vehicle systems perspective. The vehicle
