Background: Gallbladder cancer (GBC) is an aggressive, uncommon malignancy, with variation in operative approaches adopted across centres and few large-scale studies to guide practice. We aimed to identify the extent of heterogeneity in GBC internationally to better inform the need for future multicentre studies. Methods: A 34-question online survey was disseminated to members of the European-Afri

In the context of the exponential growth of data, the Covid 19 pandemic and the need for quick adaptation faced by companies, as well as by society at large, the concept of organisational learning is flourishing and becoming an even more critical component of organisational survival and growth. This study applies a socio-technical lens to shed light on the organisational learning processes taking

Alpine ecosystems harbor remarkably diverse and distinct plant communities that are characteristically limited to harsh, and cold climatic conditions. As a result of thermal limitation to species occurrence, mountainous ecosystems are considered to be particularly sensitive to climate change. Our understanding of the impact of climate change is mainly based on vascular plants however, whereas cryp

This paper presents a joint numerical and experimental study of the ignition process and flame structures in a gasoline partially premixed combustion (PPC) engine. The numerical simulation is based on a five-dimension Flamelet-Generated Manifold (5D-FGM) tabulation approach and large eddy simulation (LES). The spray and combustion process in an optical PPC engine fueled with a primary reference fu

Plasmodium relictum is the most widespread avian malaria parasite in the world. It is listed as one of the 100 most dangerous invasive species, having been responsible for the extinction of several endemic bird species, and the near-demise of several others. Here we present the first transcriptomic study focused on the effect of P. relictum on the immune system of its vector (the mosquito Culex qu

Most studies have been carried out to investigate the surface integrity induced by metal cutting process. However, the previous studies are limited to a longitudinal turning or orthogonal cutting operations and the residual stresses generated in a fillet radius have been ignored. This study uses a combination of experiments and numerical simulations to study the evolution of cutting forces, temper

For the broader industrial usage of metal additive manufactured parts, especially made by laser powder bed fusion, a better prediction and understanding of the warpage and of eigenstresses within the final part are necessary. Due to the diverse and sophisticated metallurgical and thermal processes during production, physically motivated simulations are rather complex and time consuming. Therefore,

This study investigates the ways in which age and gender play out on the LinkedIn pages of global staffing agencies through an intersectionality lens. A discourse analysis of 437 LinkedIn posts (including visual images, captions, and comments) was conducted. This study found that the corporate discourse of diversity shaped the ways that age and gender were represented. The portrayals of age and ge

Focusing on the debates on ‘due impartiality’ provided to far-right leaders in Swedish media, this article uses a Lacanian approach to address the relationship between the practices of normalisation of far-right discourses and fantasies, and the evolution of emotional governance at the interstice of old (i.e. traditional) and new (e.g. social media) media. Emotional governance refers to the everyd

In this paper, we extend the notion of affine shape, introduced by Sparr, from finite point sets to curves. The extension makes it possible to reconstruct 3D-curves up to projective transformations, from a number of their 2D-projections. We also extend the bundle adjustment technique from point features to curves. The first step of the curve reconstruction algorithm is based on affine shape, is in

Fe(III) complexes with N-heterocyclic carbene (NHC) ligands belong to the rare examples of Earth-abundant transition metal complexes with long-lived luminescent charge-transfer excited states that enable applications as photosensitizers for charge separation reactions. We report three new hexa-NHC complexes of this class: [Fe(brphtmeimb)2]PF6(brphtmeimb = [(4-bromophenyl)tris(3-methylimidazol-2-yl

Results on integration of InAs on W films through template assisted selective epitaxy are presented. The InAs crystals are analysed using SEM, electron beam backscattering and in-situ electrical measurements. A high yield of single crystalline InAs can be obtained for certain template diameters and pitches which demonstrates that this is a viable route to integrate III-V semiconductors in the back

The medical imaging technique called “ultrasound optical tomography” (UOT) entails light scattered in tissue that is given spatial information by interacting with an ultrasound field, thus allowing for molecular information to be imaged with ultrasonic resolution. This thesis discusses how UOT can be implemented, with most attention put toward the implementation using spectral-hole-burning filters
