Aerobic vaginitis diagnosis criteria combining gram stain with clinical features University of Antwerp
Wet-mount microscopy aerobic vaginitis (AV) diagnostic criteria need phase-contrast microscopy and keen microscopists, and the preservation of saline smears is less common in clinical practice. This research work developed new AV diagnostic criteria that combine Gram stain with clinical features. We enrolled 325 AV patients and 325 controls as a study population to develop new AV diagnostic criteria. Then, an independent group, which included ...
Intestinal immune cell quantification and gram type classification of the adherent microbiota in conventionally and artificially reared, normal and low birth weight piglets University of Antwerp
To be able to raise larger litters, the influences of alternative rearing strategies on piglets are currently assessed. This study compared the predominant Gram type of the adherent intestinal microbiota between conventionally and artificially reared piglets and quantified their major mucosal immune cell populations. In addition, the potential influence of the piglets' birth weights was examined. To this purpose, 40 neonatal piglets consisting ...
The FRAM robotic telescope for atmospheric monitoring at the Pierre Auger Observatory Vrije Universiteit Brussel
FRAM (F/Photometric Robotic Atmospheric Monitor) is a robotic telescope operated at the Pierre Auger Observatory in Argentina for the purposes of atmospheric monitoring using stellar photometry. As a passive system which does not produce any light that could interfere with the observations of the fluorescence telescopes of the observatory, it complements the active monitoring systems that use lasers. We discuss the applications of stellar ...
Onchocerca volvulus transmission in the Mbam valley of Cameroon following 16 years of annual community-directed treatment with ivermectin, and the description of a new cytotype of Simulium squamosum University of Antwerp Institute of Tropical Medicine
Background: The onchocerciasis focus surrounding the lower Mbam and Sanaga rivers, where Onchocerca volvulus is transmitted by Simulium damnosum s.l. (Diptera: Simuliidae), was historically the largest in the southern regions of Cameroon. Annual community- directed treatment with ivermectin (CDTI) has been taking place since 2000, but recent studies have shown that new infections are occurring in children. We aimed to investigate blackfly biting ...
Write-Verify Scheme for IGZO DRAM in Analog in-Memory Computing Interuniversity Microelectronics Centre
Large weight variations cause significant degradation in Deep Neural Networks (DNNs) accuracy in machine learning (ML) context. Indium-Gallium-Zinc-Oxide (IGZO) DRAM compute cell is a promising option for Analog in-Memory Computing (AiMC) accelerators, but its applicability requires the compensation of large variations affecting the voltage threshold of the readout device. This paper proposes a write-verify scheme for IGZO-based AiMC ...
Should MRAs be at the front row in heart failure? A plea for the early use of mineralocorticoid receptor antagonists in medical therapy for heart failure based on clinical experience KU Leuven
The brand new 2016 ESC guidelines for the treatment of acute and chronic heart failure continue to give a prominent place to mineralocorticoid receptor antagonists in the treatment of chronic heart failure with reduced ejection fraction (HFrEF). In the prevention of HF hospitalization and death, a class I, level of recommendation A, is given to MRAs for patients with HFrEF, who remain symptomatic despite treatment with an ACE-inhibitor and a ...
Low leakage ZrO2 based capacitors for sub 20 nm DRAM technology nodes KU Leuven
During DRAM capacitor scaling a lot of effort was spent searching for new material stacks to overcome the scaling limitations of the current material stack, such as leakage and sufficient capacitance. In this study, very promising results for a SrTiO3 based capacitor with a record low capacitance equivalent thickness value of 0.2 nm at target leakage current are presented. Due to the material properties of SrTiO3 films (high vacancy ...
0.5 nm EOT low leakage ALD SrTiO3 on TiN MIM capacitors for DRAM applications KU Leuven Ghent University
We demonstrate for the first time record low Leakage-EOT (3.5×10 -7 A/cm2at 1V, EOT=0.49 nm) MIM capacitors fabricated using a low temperature (250°C) ALD SrTiO3 (STO) deposition process on ALD TiN bottom electrode. While most previous work on STO used deposition techniques not compatible with high aspect ratio DRAM applications, recent work on ALD STO showed promise on noble-like metal electrodes (Ru, Pt) [1,2]. In this work, a low temperature ...
