The evolution of the fifth-generation network (5G) increases the demand and use of Internet of Things (IoT) devices extensively. The increased number of IoT devices increases the possibility of new attack surfaces, and thus even resource-constrained IoT devices need secure communication. In this work, we consider the Julia Key Agreement (JKA) protocol, which has been proposed as a secure and effic
The role of the vitamin D receptor (VDR) in inflammatory bowel disease (IBD) is poorly described. The aim of this study was to examine the relationship between immunohistochemical VDR expression and IBD activity. The immunohistochemical expression of VDR was analysed in biopsies from active and inactive IBD in 28 patients (ulcerative colitis: 21, Crohn's disease: 7) and 12 non-IBD controls. VDR ex
Software is at the core of digitalisation and is often claimed to play a central role in innovation and in shaping competition across industries and firms. There are yet few studies of the extent and nature of software development across firms. We employ a unique firm-level survey comprising 3,929 firms across Sweden to analyse the distribution and characteristics of firms that invest in software
For the past decade, the sharing economy has not only grown but also expanded to cover a wide variety of different activities across the globe. Despite a lot of research, there is still no agreement on how to define and measure the sharing economy, and no consensus on whether the sharing economy is a part of or an alternative to a regular capitalist economy. This paper contributes by presenting a
Background: Certain species from the normal respiratory tract microbiota have recently been proposed to positively influence human health. Corynebacterium propinquum and C. pseudodiphtheriticum (Corynebacteria) are two Gram-positive species that frequently colonize the upper respiratory tract and strongly associate with a reduced incidence of respiratory tract infections. The specific role of Cory
While digitalisation is oftentimes thought of as a global megatrend and something that transcends national borders and geographical distances, it is at the same time a very tangible process exhibiting considerable regional and sectoral variation. Against this backdrop, Digital Innovation Hubs (DIHs) (a policy initiative in the context of the Digitising European Industry (DEI) strategy of the EU) c
Digitaliseringen och utvecklingen av en ny generation artificiell intelligens (AI) medför betydande förändring i ekonomi och samhälle. Men hur den förändringen ser ut beror inte bara på den nya tekniken, utan också på hur den till slut används. Tekniska framsteg har genom historien spelat en avgörande roll för långsiktig tillväxt och välståndsökningar, men produktivitetsökningar kommer inte gratis
In this paper we explore cyber security practices in Swedish manufacturing firms. Manufacturing is being trans- formed by new technologies under the label of smart industry or industry 4.0. Most of these technologies are either digital themselves or depend on digital connectivity. Their use is made possible by electronic sensors, actuators, and other devices as well as by data-driven analysis. Thi
The definition of a decision support system(DSS) may be : human-computer interactive software system to solve semi-structured decisional problems for decisional makers with data utilizing, information management, knowledge, as well as model techniques. DSS only provide supporting information about making decision for the decision maker without stipulate the decision itself. Decision is made by hum
Cerebellar mutism syndrome (CMS) has received increasing attention over the last decades as a complication of posterior fossa tumour surgery in children. Risk factors, aetiological aspects, and treatment measures of the syndrome have been investigated, yet the incidence of CMS remains unchanged. Overall, we are currently able to identify patients at risk, but we are unable to prevent it from occur
Often treated as simply anti-modernism, a focus on three reformist figures with transnational intellectual ties—Shariat Sangelaji, Asadollah Kharaqani, and Muhammad Khalesizadeh—reveals how Iranian natives of the Gulf littoral contributed to reconstitute modern life by criticizing the global structures of power arising with European imperialism. Blurring the dichotomy of modern/traditional, Iran a
Background: Real-time (RT) phase contrast (PC) flow MRI can potentially be used to measure blood flow in arrhythmic patients. Undersampled RT PC has been combined with online compressed sensing (CS) reconstruction (CS RT) enabling clinical use. However, CS RT flow has not been validated in a clinical setting. Purpose: Evaluate CS RT in phantom and patients. Study Type: Prospective. Population: Flo
Atrial fibrillation (AF) is common condition among the elderly, and leads toincreased risks of stroke, heart failure, dementia, and death. Diagnosing AF requires electrocardiograms (ECGs), and long recordings may be necessary since AF often occurs intermittently in its early stages. During AF, the heart rate is irregular, and sometimes inappropriately fast. This thesis includes four papers that st
Attempts to use colloid science concepts to better understand the dynamic properties of concentrated or crowded protein solutions are challenging due to the fact that globular proteins generally have heterogeneous surfaces that result in anisotropic or patchy contributions to their interaction potential. This is particularly difficult when targeting non-equilibrium transitions such as glass and ge
The first ICDRG (International Contact Dermatitis Research Group) classification of patch test reactions was published in 1970. With this classification, many weak reactions were classified as allergic reactions. A second classification was therefore implemented one decade later on behalf of the ICDRG and the North American Contact Dermatitis Group. This classification was adopted by the European
Land use change from agricultural intensification has been highlighted as one of the major drivers of global declines in insects, reducing species diversity and abundance and shifting community composition towards generalist species. However, it remains a challenge to determine how land use change impacts the genetic diversity of species and populations even if this diversity is vital to their lon
Global climate change is one of the greatest environmental threats facing humanity and it is affecting every country on every continent. Recent evidence confirms a close liaison between climate change induced hazards and the built environment, as the built environment demonstrates a high fragility and vulnerability to hazardous situations. The impact of climate change is particularly pertinent to
