Beamforming technology plays a significant role in source localization and quantification. As traditional delay-and-sum beamformers generally yield low spatial resolution, as well as suffer from the occurrence of spurious sources, different forms of deconvolution methods have been proposed in the literature. In this work, we propose two approaches based on a sparse reconstruction framework combine

This paper investigates the stabilization of underactuated vehicles moving in a three-dimensional vector space. The vehicle's model is established on the matrix Lie group SE(3), which describes the configuration of rigid bodies globally and uniquely. We focus on the kinematic model of the underactuated vehicle, which features an underactuation form that has no sway and heave velocity. To compensat

The usefulness of blood culture time-to-positivity (TTP) in the diagnosis of endovascular infections has previously been shown. Here, we investigated TTP in 41 patients with F. necrophorum bacteraemia and found an association between short TTP and Lemierre's syndrome (p = 0.026).

Background: There is an increasing interest in the potential health benefits of positive psychological states, especially with regard to cardiovascular health. Life satisfaction is thought to be a constituent component of psychological well-being; however, among the few previous studies that have investigated its associations with early stages of the cardiovascular disease process, only one small

Information Systems Interactions are a pivotal point in developing an understanding of a socio-technical system. From this perspective, Information Systems could be defined as the cooperation, coexistence and integration of a socio-technical approach with the social aspect. This research investigates how people communicate in a business and how this is likely to support knowledge sharing practices

Behind everything we do in our daily lives there is a reason for doing it. This paper looks into the motives behind DDoS attacks as a form of cyberattack along with attacker personas. This paper also investigates DDoS attacks technically and it is suggested that there is a need for a socio-technical approach to these attacks to investigate why they occur and the reasoning the attacker(s) could hav

Due to improved laboratory techniques, touched surfaces and items are increasingly employed as sources of forensic DNA evidence. This has urged a need to better understand the mechanisms of DNA transfer between individuals. Shedder status (i.e. the propensity to leave DNA behind) has been identified as one major factor regulating DNA transfer. It is known that some individuals tend to shed more DN

Purpose: Hypoxia (low oxygen) is a common feature of solid tumors that has been intensely studied for more than six decades. Here we review the importance of hypoxia to radiotherapy with a particular focus on the contribution of hypoxia to immune responses, metastatic potential and FLASH radiotherapy, active areas of research by leading women in the field. Conclusion: Although hypoxia-driven metas

PurposeThe aim of this study was to better understand the attitudes towards the use of technology to support chronic stroke survivors in a home-based setting.MethodsA quantitative study was used on the data obtained from a face to face survey with the sample group, incorporating quantitative statistical analysis.ResultsParticipants reported positive attitudes towards using technology for their own

This paper is about the socio-technical findings of a project that was carried out for an organisation in the educational sector. The main aim of the project was to explore the possibilities of developing a mobile Augmented Reality authoring tool that educators would use to create AR experiences in attempt to improve their teaching methods. A novel ‘solution’ was designed and prototyped, which ini

Sustainability is rarely implemented in employee work practices in small and medium-sized enterprises (SMEs). The authors note that SMEs should implement sustainability practices as integrated part of work activities to ensure long term success. This paper describes an empirical study of SMEs sustainability on employee real work practices. A relevant perspective is offered by the triple bottom lin

Background: Community services for Swedish people with intellectual disability (ID) are intended to support self-determination and integrity. Legislation does not allow the use of restrictive or coercive measures. Aim: The aim of this study is to identify the extent of, rationale for, and strategies staff believe would reduce the use of restrictive measures in group homes and daily activities serv

Background: Cases of allergic contact dermatitis (ACD) caused by isobornyl acrylate (IBOA) in the Omnipod® insulin pump have previously been reported. Objectives: To present three cases of patients with ACD caused by a new allergen in the pump, and results from chemical analyses. Methods: Omnipod pumps from different batches were analysed by gas chromatography–mass spectrometry. Aimed testing, wit

Background and aims: A high body mass index (BMI) is considered a risk factor for ventral abdominal wall hernias but protective for the development of groin hernias. The reason for this is unclear. The surrounding abdominal fat in obesity might “protect” and limit the passage through the inguinal canal. The aim was to compare two different methods used for obesity registration in groin hernia pati

Objective: Rathke's cleft cysts are benign, embryological remnants in the pituitary gland. The majority of them are small and asymptomatic but a few may become large, and cause mass effects, pituitary hormone deficiencies and visual impairment. Recommendations for the follow-up of Rathke's cleft cysts vary since data on the natural history are sparse. Patients and Design: Data at diagnosis and at

In 2009, the International Soil Moisture Network (ISMN) was initiated as a community effort, funded by the European Space Agency, to serve as a centralised data hosting facility for globally available in situ soil moisture measurements . The ISMN brings together in situ soil moisture measurements collected and freely shared by a multitude of organisations, harmonises them in terms of units and sam
