Role of machine and organizational structure in science

The progress of science increasingly relies on machine learning (ML) and machines work alongside humans in various domains of science. This study investigates the team structure of ML-related projects and analyzes the contribution of ML to scientific knowledge production under different team structure, drawing on bibliometric analyses of 25,000 scientific publications in various disciplines. Our r

The Effects of the Academic Environment on PhD Entrepreneurship : New Insights from Survey Data

This paper investigates PhD entrepreneurship. We focus on the university factors most closely associated to: (1) students’ success in starting a business venture; (2) students’ startup intention; (3) students’ abandoning the entrepreneurial idea. The empirical analysis is based on data from a questionnaire survey, administered in 2016 in Italy. We focus on four factors related to the university en

Interactions between β-haemolytic streptococci and the human host. Heart, skin and beyond.

Group C and G streptococci (GCS/GGS) and group A streptococci (GAS) belong to β-haemolytic streptococci (BHS). GCS/GGS can further be species determined to S. dysgalactiae, whereas S. pyogenes are GAS. S. dysgalactiae and S. pyogenes cause similar diseases, (e.g., skin and soft tissue infections, erysipelas, bacteraemia, and infective endocarditis (IE)). Erysipelas often presents as a sharply dema

Reciprocity and challenge in researcher-student collaborative labour in a multilingual secondary school

This chapter focuses on challenge and reciprocity in researcher-student collaborative labour (Zigo 2001) in a large multilingual secondary school in Sweden. The school was recruited for a larger longitudinal study of classroom language policy. For the purposes of the present chapter, we analysed ethnographic data to shed light on the well-known challenge of recruiting and retaining students to par

Low-temperature nanoscale heat transport in a gadolinium iron garnet heterostructure probed by ultrafast x-ray diffraction

Time-resolved x-ray diffraction has been used to measure the low-temperature thermal transport properties of a Pt/Gd3Fe5O12//Gd3Ga5O12 metal/oxide heterostructure relevant to applications in spin caloritronics. A pulsed femtosecond optical signal produces a rapid temperature rise in the Pt layer, followed by heat transport into the Gd3Fe5O12 (GdIG) thin film and the Gd3Ga5O12 (GGG) substrate. The

Calcium Load in the Aortic Valve, Aortic Root, and Left Ventricular Outflow Tract and the Risk for a Periprocedural Stroke

Background: Periprocedural stroke during transcatheter aortic valve implantation is a rare but devastating complication. The calcified aortic valve is the most likely source of the emboli in a periprocedural stroke. The total load and distribution of calcium in the leaflets, aortic root, and left ventricular outflow tract varies from patient to patient. Consequently, there could be patterns of cal

Distributed and Scalable Uplink Processing for LIS : Algorithm, Architecture, and Design Trade-Offs

The Large Intelligent Surface (LIS) is a promising technology in the areas of wireless communication, remote sensing and positioning. It consists of a continuous radiating surface located in the proximity of the users, with the capability to communicate by transmission and reception (replacing base stations). Despite its potential, there are numerous challenges from an implementation point of view

Growth selectivity control of InAs shells on crystal phase engineered GaAs nanowires

In this work we demonstrate a two-fold selectivity control of InAs shells grown on crystal phase and morphology engineered GaAs nanowire (NW) core templates. This selectivity occurs driven by differences in surface energies of the NW core facets. The occurrence of the different facets itself is controlled by either forming different crystal phases or additional tuning of the core NW morphology. Fi

Hearing loss after bacterial meningitis, a retrospective study

Background: Hearing loss is a common sequela after bacterial meningitis, but risk factors for this are poorly studied, particularly in relation to concurrent acute otitis media (AOM). Aims: The aim of this study was to investigate incidence and risk factors for hearing loss in patients treated for bacterial meningitis. Methods: In this retrospective study, medical records for patients admitted to

Advanced cancer and concomitant dementia : access to specialized palliative care, emergency room, hospital care, and place of death

Background: Dementia and advanced cancer are complex, life-limiting conditions that benefit from specialized palliative care (SPC) interventions at the end of life. The objective was to study possible differences in care for patients with concomitant advanced cancer and dementia (CA-DEM) or cancer only (CA) regarding access to SPC, acute hospital care, and place of death. Materials and methods: A

A 12-GHz Reconfigurable Multicore CMOS DCO, With a Time-Variant Analysis of the Impact of Reconfiguration Switches on Phase Noise

This article introduces a 28-nm CMOS digitally controlled oscillator (DCO) based on eight oscillator cores, where the number of active cores can be reconfigured to be either 2, 4, 6, or 8, trading power consumption for phase noise without incurring an additional phase noise penalty. The impact of the reconfiguration pMOS switches on the phase noise performance is determined through a simple yet ri

How older adults relate to their own voices : a qualitative study of subjective experiences of the aging voice

Aim: The aim of this study was to investigate how otherwise healthy older adults with self-assessed voice problems relate to their voice and voice changes. Method: Focus groups were conducted at an activity center to identify how older adults reflect on their own voice and the aging voice in general. The interviews were audio recorded and transcribed. The analysis was done using thematic content a

Exporting Journalism Culture to Vietnam : The Role of the Trainer in Two Swedish Media Aid Projects

In this paper, I explored how two media aid projects from Sweden were used to intervene in the development of Vietnamese journalism between 1993 and 2007. Vietnamese journalism and media aid are contextualized in this paper by unfolding pedagogical ideology, journalistic culture, and the negotiation of professional ideals. Based on an interview study with Swedish trainers from the media aid projec

Estimation of recent peat accumulation with tree saplings

The purpose of this paper is to develop an approach to estimate peat accumulation rates (PAR) over recent decades based on the age and burial depths of roots from pine sapling and to use the newly developed approach to estimate spatial variations of PAR. To this end, we sampled 120 pine saplings growing in three plots at Rėkyva peatland in Lithuania and accounted for the microtopography around eac

Adrenomedullin in sepsis

AbstractBackgroundSepsis is a syndrome difficult to diagnose and stratify. The epidemiology of sepsis and consistency of criteria fulfillment with diagnosis coding in Swedish intensive care units (ICU) are largely unknown. Biomarkers can be of help to understand pathophysiology, identify clusters within sepsis and to individualize treatment.AimThe overarching aim of this thesis was to explore how
