Are firms withdrawing from basic research? An analysis of firm-level publication behaviour in Germany

Previous research has expressed concerns about firms engaging less in basic research. We contribute to this debate by studying trends in the scientific publishing activities of firms located in Germany. Our results indicate that the firms’ aggregate volume of scientific publications stayed constant between 2008 and 2016. However, the number and share of publishing firms declined, and publication a

The Rich Kids of Instagram : Luxury Travel, Transport Modes, and Desire

The Rich Kids of Instagram (RKOI) portray luxury lifestyles on social media. The potential roles of travel and transport within these online displays of affluence have not yet been examined. This paper’s purpose is to analyse how transport modes and luxury travel are depicted and interrelated through RKOI images. Co-occurrence analyses were conducted using a data set of Instagram posts with RKOI a

Urostomal ileal conduit complications in association with abdominal wall mesh implantation

Objective: Parastomal hernia (PH) in association with an ileal conduit is a common complication that is difficult to treat. Mesh reinforcement has been suggested to improve outcomes; either as prophylaxis or for treatment of a parastomal hernia during abdominal wall reconstruction. Patients and methods: A retrospective study was performed in consecutive patients subjected to mesh implantation betw

Prognostic Significance of Chest Imaging by LUS and CT in COVID-19 Inpatients : The ECOVID Multicenter Study

Background: Point-of-care lung ultrasound (LUS) score is a semiquantitative score of lung damage severity. High-resolution computed tomography (HRCT) is the gold standard method to evaluate the severity of lung involvement from the novel coronavirus disease (COVID-19). Few studies have investigated the clinical significance of LUS and HRCT scores in patients with COVID-19. Therefore, the aim of th

Deep learning-based classification and structure name standardization for organ at risk and target delineations in prostate cancer radiotherapy

Radiotherapy (RT) datasets can suffer from variations in annotation of organ at risk (OAR) and target structures. Annotation standards exist, but their description for prostate targets is limited. This restricts the use of such data for supervised machine learning purposes as it requires properly annotated data. The aim of this work was to develop a modality independent deep learning (DL) model fo

Our aim was to assess the incidence of symptomatic ulnar nerve dislocation and its influence on surgical outcome after primary and revision surgeries in ulnar nerve entrapment at the elbow (ulnar neuropathy at the elbow (UNE) or cubital tunnel syndrome). The influence of pre- or intra-operative ulnar nerve dislocation on postoperative outcome was assessed in 548 surgically treated cases (548 nerve

Open vs minimally invasive radical trachelectomy in early-stage cervical cancer : International Radical Trachelectomy Assessment Study

Background: Minimally invasive radical trachelectomy has emerged as an alternative to open radical hysterectomy for patients with early-stage cervical cancer desiring future fertility. Recent data suggest worse oncologic outcomes after minimally invasive radical hysterectomy than after open radical hysterectomy in stage I cervical cancer. Objective: We aimed to compare 4.5-year disease-free surviv

Cooperative event-based rigid formation control

This article discusses cooperative stabilization control of rigid formations via an event-based approach. We first design a centralized event-based formation control system, in which a central event controller determines the next triggering time and broadcasts the event signal to all the agents for control input update. We then build on this approach to propose a distributed event control strategy

aYChr-DB : a database of ancient human Y haplogroups

Ancient Y-Chromosomal DNA is an invaluable tool for dating and discerning the origins of migration routes and demographic processes that occurred thousands of years ago. Driven by the adoption of high-throughput sequencing and capture enrichment methods in paleogenomics, the number of published ancient genomes has nearly quadrupled within the last three years (2018-2020). Whereas ancient mtDNA hap

Service quality in social media communication of NPOs : The moderating effect of channel choice

Social media communication is attractive for non-profit organizations (NPOs); however, the channels of social media are not homogeneous; a factor not sufficiently considered by empirical research. We address this gap by looking into the moderating effect of social media channel choice on the impact of brand trust on process and outcome quality. By surveying 174 customers of an Austrian NPO, we ana

Comparing the Clinical Utility and Diagnostic Performance of Cerebrospinal Fluid P-Tau181, P-Tau217 and P-Tau231 Assays

BACKGROUND AND OBJECTIVES: Phosphorylated tau (P-tau) in cerebrospinal fluid (CSF) is considered an important biomarker in Alzheimer's disease (AD) and has been incorporated in recent diagnostic criteria. Several variants exist, including P-tau at threonines 181 (P-tau181), 217 (P-tau217) and 231 (P-tau231). However, no studies have compared their diagnostic performance or association to amyloid-β

Empowering industry 4.0 and autonomous drone scouting use cases through 5G-DIVE solution

The 5G Edge Intelligence for Vertical Experimentation (5G-DIVE) project aims at demonstrating the technical merits and business value proposition of 5G technologies in two vertical pilots, namely the Industry 4.0 (I4.0) and Autonomous Drones Scout (ADS) pilots. This paper presents an overview of the overall 5G-DIVE solution and reports the results of the initial validation campaign of the selected

DEEP : A Vertical-Oriented Intelligent and Automated Platform for the Edge and Fog

The fifth generation (5G) of mobile communications introduces improvements on many fronts when compared to its previous generations. Besides the performance enhancements and new advances in radio technologies, it also integrates other technological domains, such as cloud-to-things continuum and artificial intelligence. In this work, the 5G-DIVE Elastic Edge Platform (DEEP) is proposed as the linki

Potential role of an athlete-focused echocardiogram in sports eligibility

Sudden cardiac death (SCD) of an athlete is a rare but tragic event and sport activity might play a trigger role in athletes with underlying structural or electrical heart diseases. Preparticipation screenings (PPs) have been conceived for the potential to prevent SCD in young athletes by early identification of cardiac diseases. The European Society of Cardiology protocol for PPs includes history
