Steps at metal surfaces may influence energetics and kinetics of catalytic reactions in unexpected ways. Here, we report a significant reduction of the CO saturation coverage in Pd vicinal surfaces, which in turn is relevant for the light-off of the CO oxidation reaction. The study is based on a systematic investigation of CO adsorption on vicinal Pd(111) surfaces making use of a curved Pd crystal

Objective: Papillary urothelial neoplasm of low malignant potential (PUNLMP) and stage TaG1 non-muscle invasive bladder cancer (NMIBC) represent separate categories in current WHO 1999 grade definitions. Similarly, PUNLMP and Ta low-grade are separate entities in the WHO 2004/2016 grading system. However, this classification is currently questioned by reports showing a similar risk of recurrence a

Transcriptional profiling of acute leukemia, specifically by RNA-sequencing or whole transcriptome sequencing (WTS), has provided fundamental insights into its underlying disease biology and allows unbiased detection of oncogenic gene fusions, as well as of gene expression signatures that can be used for improved disease classification. While used as a research tool for many years, RNA-sequencing

Cystatin C is a human cysteine proteinase inhibitor present in extracellular fluids. Cystatin C and a tripeptide derivative (Z-LVG-CHN2) that mimics its proteinase-binding center, were tested for possible antiviral activity against herpes simplex virus type 1 (HSV) and poliovirus type 1. Both recombinant cystatin C and Z-LVG-CHN2 displayed strong inhibitory effects on HSV replication, whereas no s

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 (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

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

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

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

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

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

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

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

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
