First observations and performance of the RPW instrument onboard the Solar Orbiter mission

The Radio and Plasma Waves (RPW) instrument on the ESA Solar Orbiter mission is designed to measure in situ magnetic and electric fields and waves from the continuum up to several hundred kHz. The RPW also observes solar and heliospheric radio emissions up to 16 MHz. It was switched on and its antennae were successfully deployed two days after the launch of Solar Orbiter on February 10, 2020. Since then, the instrument has acquired enough data to make it possible to assess its performance and the electromagnetic disturbances it experiences. In this article, we assess its scientific performance and present the first RPW observations. In particular, we focus on a statistical analysis of the first observations of interplanetary dust by the instrument’s Thermal Noise Receiver. We also review the electro-magnetic disturbances that RPW suffers, especially those which potential users of the instrument data should be aware of before starting their research work

Perceived Lightness/Darkness and Warmth/Coolness in Chromatic Experience

There are widespread beliefs that red, orange, and yellow are warm colors while blue, green, and purple are cool. In addition, some colors, like yellow, are said to be lighter than others, such as blue. The present study investigated how the psychological dimensions of hue, saturation and lightness contribute to these distinctions, and attempted to relate ratings of these attributes to the Opponent Process Theory. Subjects rated colored chips from the Natural Color System atlas for their warmth/coolness or lightness/darkness. Increases in the percentage of saturation in a color produced warmer ratings with the specific amount of increase depending on the hue. Changes in lightness did not significantly affect warmth/coolness ratings. Increases in saturation and in blackness both produced darker ratings, but the size of the increase in ratings depended on the hue. In addition, hues associated with longer wavelengths were rated as warmer than those associated with shorter wavelengths, while hue had no significant effects on ratings of lightness/darkness. Furthermore, higher ratings of warmth were found to correspond with opponent channel activation in one direction, while lower ratings corresponded with activation in the opposite direction. This suggests that warmth ratings may be associated with the low-level physiological processes involved in color perception, rather than with the psychological dimension of hue, and that the attribution of thermal properties to colors may be more than simply a cognitive process

ASTERICS – advanced simulation models and accelerated testing for the development of electric vehicles

AbstractThe development of Electric Vehicles (EV's), either fully electric (BEV…battery electric vehicle) or different hybrids (like HEV… hybrid electric vehicles or PHEV…plug-in hybrids), is an undeniable prerequisite to fulfill the worldwide emission targets for transport even within the next 10-15 years. The conventional development methods and tools on the other hand, are so far only optimized for the development of vehicles with ICE engines only and not well designed to develop EV's at all. To close this gap, the research in ASTERICS is focused on simulation and testing methods as well as tools that enable the optimal, cost efficient and safe development of EV's. Realistic driving cycles for e-vehicles, models for e-components, test procedures, test equipment and tools as well as system simulation and evaluation have been investigated in, which lasted 3 years (Oct. 2012 – Sept. 2015) and involved 10 partners (OEM: CRV, Volvo; Supplier: AVL, Siemens SAS/SISW, Thien eDrives, GustavKlein; Research: see above)

Cardiac resynchronization therapy may benefit patients with left ventricular ejection fraction > 35%: a PROSPECT trial substudy

Cardiac resynchronization therapy (CRT) is currently limited to those with left ventricular ejection fraction (LVEF) 35% might benefit from CRT, we performed a retrospective analysis of the predictors of response to CRT (PROSPECT) database. PROSPECT was a prospective, multicentre study that enrolled CRT patients based on enrolling centre-evaluated LVEF 35% (OVER35) were compared with those whose LVEF was 35%. At entry, OVER35 had smaller LV volumes, shorter QRS duration, shorter 6-min walk distance, and were more likely to have ischaemic aetiology than UNDER35. Outcomes were comparable between the groups, with 62.8% of OVER35 improved in CCS (70.2% in UNDER35) and 50.8% of OVER35 improved in LVESV (57.8% in UNDER35). Patients with LVEF > 35%, New York heart association functional Class III-IV status, and QRS > 130 ms appear to derive clinical and structural benefit from CRT. As CRT may offer a valuable option for these patients, this hypothesis should be formally tested in a prospective, randomized multicentre trial.Cardiac Dysfunction and Arrhythmia

Comparison of Helicobacter Pylori Genotypes Obtained from the Oropharynx and Stomach of the Same Individuals – A Pilot Study

Helicobacter pylori has been recently detected in the oral cavity and oropharynx. However, the role it plays in oral and oropharyngeal pathogenesis remains unclear. The virulence of H. pylori strains can be distinguished according to the virulence factors genes carried. Our research has been focused on realtime PCR analysis of cagA and vacA genes of H. pylori strains in tonsils and tonsillar squamous cell cancer and their comparison with H. pylori strains obtained from the gastric mucosa of the same patients. Urea breath test (UBT) test was used to detect a gastric H. pylori infection in 20 patients with previously proven H. pylori in the oropharynx. Genotyping of H. pylori in gastric biopsies was performed in patients with positive gastric infection. Out of 20 patients positive for oropharyngeal H. pylori, 8 were positive for concurrent gastric H. pylori infection. In 6 of them gastric biopsies were obtained. Comparison of oropharyngeal and stomach H. pylori genotypes showed important differences. Four of 6 patients had different H. pylori strains in the oropharynx and stomach. The differences were found in cagA gene as well as in vacA gene. The finding of oral presence of H. pylori without concurrent stomach infection was confirmed using UBT. The results show that more than one H. pylori strain can be present in oropharynx and stomach in the same patient. The oropharyngeal infection seems to be independent to the gastric infection

The first simultaneous observation of low energy ions and electrons at Mercury during the first BepiColombo flyby

International audienceThe first Mercury flyby by BepiColombo was successfully conducted on the 1st of October 2021 and this is the first time to have the simultaneous observation of low energy ions and electrons at Mercury. The data from Mercury Plasma Particle Experiment (MPPE) onboard Mio/BepiColombo shows (1) the compressed Mercury's magnetosphere compared to the average of MESSENGER observations, (2) boundary motions around magnetopause crossings, (3) periodic signatures in ion and electron spectra in both dawn- and dusk- night sides, which is most likely the ULF waves, and (4) high energy ions and electrons after the closest approach, which indicates the substorm related injection. Detailed analysis of these features will be addressed in the presentation, and compare them with previous MESSENGER and Mariner-10 observations
