Parallel matters : Efficient polyp segmentation with parallel structured feature augmentation modules

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

Between Law and Safety : Licensed Aircraft Maintenance Engineers and the Socio-professional Construction of Legality in European Civil Aviation

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

Investigating the Electromechanical Behavior of Unconventionally Ferroelectric Hf0.5Zr0.5O2-Based Capacitors Through Operando Nanobeam X-Ray Diffraction

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

A geofencing-based methodology for speed limit regulation and user safety in e-scooter sharing systems

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

Quantifying extinction imaging of fuel sprays considering scattering errors

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

Plasma phosphorylated tau 217 in preclinical Alzheimer's disease

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

What is the point of method sections?

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

Leadership and the stings of command

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

Theory's best practice

Why is theorizing important? What does it do? This note reflects on the broad question of what we do when we theorize, taking its starting point from the Greek notion of theoria. The argument is that theorizing as an uncertain journey, i.e. as a form of travelling along a path towards the unknown or unfamiliar, has unjustly fallen into disrepute. The notion of ‘theory’ is today primarily associate

Ingen vill sluta avtal med en regering som bryter löften

När regeringen, pressad av SD, inte följer ingångna avtal bryter den med svensk tradition. Historiskt har trepartsmodellen haft framgång i att lösa viktiga samhällsproblem. Med staten som opålitlig part riskeras något av det mest svenska vi har, skriver German Bender på den fackföreningsnära tankesmedjan Arena Idé och professor Anders Kjellberg.

Extreme precipitation patterns in the Asia-Pacific region and its correlation with El Niño-Southern Oscillation (ENSO)

In the Asia-Pacific region (APR), extreme precipitation is one of the most critical climate stressors, affecting 60% of the population and adding pressure to governance, economic, environmental, and public health challenges. In this study, we analyzed extreme precipitation spatiotemporal trends in APR using 11 different indices and revealed the dominant factors governing precipitation amount by at

OME-Zarr : A cloud-optimized bioimaging file format with international community support

A growing community is constructing a next-generation file format (NGFF) for bioimaging to overcome problems of scalability and heterogeneity. Organized by the Open Microscopy Environment (OME), individuals and institutes across diverse modalities facing these problems have designed a format specification process (OME-NGFF) to address these needs. This paper brings together a wide range of those c

Analyzing Factors Contributing to Real-time Train Arrival Delays using Seemingly Unrelated Regression Models

Understanding the impact of various factors on train arrival delays is a prerequisite for effectiverailway traffic operating control and management. Existing studies analyze the train delayfactors using a single, generic regression equation, restricting their capability in accounting forheterogeneous impacts of spatiotemporal factors on arrival delays as the train travels along itsroute. The paper

Quantitative Methods for Train Delay Propagation Research

Due to the increase in railway traffic, trains increasingly need to adhere to their scheduled path to avoid extensive propagation ofdelays. This paper presents the findings of a systematic literature review covering articles related to the delay propagation problemsof trains. By searching both the Scopus and Web of Science databases, the content of 156 relevant papers was screened andanalyzed. The
