Near-realtime quantitative precipitation estimation and prediction (RealPEP)
Flash floods in small- to medium-sized catchments and intense precipitation over cities
caused by severe local storms pose increasing threats to our society. For the timely prediction of such events, the value of high-resolution and high-quality QPE and corresponding
forecasts cannot be overrated. Seamless predictions harmonizing nowcasting and numerical
weather prediction (NWP) across forecast lead times from minutes to days would greatly help
to improve the value and efficiency of warnings. Organized by the Research Unit on Near-Realtime Precipitation Estimation and Prediction (RealPEP, www2.meteo.uni-bonn.de/realpep)
and supported by the Project on Seamless Integrated Forecasting System (SINFONY, www.dwd
.de/DE/forschung/forschungsprogramme/sinfony_iafe/sinfony_node.html) of the German Meteorological Service (DWD), an international 3-day online conference was held from 5 to 7 October 2020,
dedicated to Precipitation and Flash-Flood Predictions from Minutes to Days (https://indico
.scc.kit.edu/event/883/). Most speakers agreed to have their presentations recorded, which we
uploaded to YouTube for further distribution (see, e.g., on the conference homepage, https://
indico.scc.kit.edu/event/883/page/588-recorded-talks).
The speakers were both invited experts in the respective research fields and researchers
from the RealPEP and SINFONY projects. Talks and discussions could be followed on video
stream. Interaction between the about 250 participants was enabled by entering written questions and comments via a dedicated tool, which allowed for voting and thus also ranking
questions. Registered participants could enter chat rooms from where they could be moved to
the speaker room for posing the questions directly to the speakers and the auditorium. On the
last day of the conference podium discussions with selected speakers summarized talks and
discussions and elaborated on overarching problems, ideas, and developments in the fields
of quantitative precipitation estimation (QPE), quantitative precipitation nowcasting (QPN),
quantitative precipitation forecasting (QPF), flash-flood prediction (FFP), and their organization into seamless prediction systems, which also constituted the topics of the five sessions
during the conference. We report here in particular on the outcomes of the panel discussions

Precipitation and microphysical processes observed by three polarimetric X-band radars and ground-based instrumentation during HOPE
This study presents a first analysis of precipitation and related
microphysical processes observed by three polarimetric X-band Doppler radars
(BoXPol, JuXPol and KiXPol) in conjunction with a ground-based network of
disdrometers, rain gauges and vertically pointing micro rain radars (MRRs)
during the High Definition Clouds and Precipitation for advancing Climate
Prediction (HD(CP)2) Observational Prototype Experiment (HOPE) during
April and May 2013 in Germany. While JuXPol and KiXPol were continuously
observing the central HOPE area near Forschungszentrum Jülich at a close
distance, BoXPol observed the area from a distance of about 48.5 km. MRRs
were deployed in the central HOPE area and one MRR close to BoXPol in Bonn,
Germany. Seven disdrometers and three rain gauges providing point
precipitation observations were deployed at five locations within a
5 km × 5 km region, while three other disdrometers were
collocated with the MRR in Bonn. The daily rainfall accumulation at each
rain gauge/disdrometer location estimated from the three X-band polarimetric
radar observations showed very good agreement. Accompanying microphysical
processes during the evolution of precipitation systems were well captured
by the polarimetric X-band radars and corroborated by independent
observations from the other ground-based instruments
Effect of Zinc Supplementation on Growth of Low Birth Weight Infants Aged 1–6 Mo in Ardabil, Iran
Objective To assess the effect of zinc supplementation on growth of low birth weight (LBW) infants aged 1–6 mo. Methods LBW infants were enrolled at birth and randomly assigned to receive 5 mg elemental Zn per day (n=45) or placebo (n=45) until 6 mo of age. They were followed monthly for information on compliance; anthropometric measurements were performed monthly. Results After randomization, 5 infants from zinc group and 9 from placebo group were excluded. At 6 mo of age, significantly greater weight gains were observed in the zinc than in the placebo group (4995±741g in zinc group vs. 3896±865 g in placebo group, p = 0.036). Length gain during the study period improved in zinc group (16.9±8.2 cm vs. 15.1±4.1 cm, p = 0.039); after zinc supplementation head circumference were increased (8.7±1.4 cm vs.7.4±
1.5 cm p<0.001). In male infants, total weight gain and height and head circumference gain were higher in the zinc than in the placebo group. However, only head circumference change was statistically significant. A similar trend was observed among female infants, but these differences were not statistically significant. There was no significant relation between breast-feeding status and the main outcome variables. Conclusions Infants in the present study showed improve¬ments in growth rate, but more studies are required in this field to confirm this fact
Synthetic heterochromatin bypasses RNAi and centromeric repeats to establish functional centromeres
In the central domain of fission yeast centromeres, the kinetochore is assembled on CENP-A cnp1 nucleosomes. Normally, small interfering RNAs generated from flanking outer repeat transcripts direct histone H3 lysine 9 methyltransferase Clr4 to homologous loci to form heterochromatin. Outer repeats, RNA interference (RNAi), and centromeric heterochromatin are required to establish CENP-A Cnpl chromatin. We demonstrated that tethering Clr4 via DNA-binding sites at euchromatic loci induces heterochromatin assembly, with or without active RNAi. This synthetic heterochromatin completely substitutes for outer repeats on plasmid-based minichromosomes, promoting de novo CENP-A Cnpl and kinetochore assembly, to allow their mitotic segregation, even with RNAi inactive. Thus, the role of outer repeats in centromere establishment is simply the provision of RNAi substrates to direct heterochromatin formation; H3K9 methylation-dependent heterochromatin is alone sufficient to form functional centromeres.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

To determine if improvements in cognitive outcome detected at 18 months' corrected age (CA) in infants born <33 weeks' gestation receiving a high-docosahexaenoic acid (DHA) compared with standard-DHA diet were sustained in early childhood.
DESIGN:
Follow-up of a multicentre randomised controlled trial. Randomisation was stratified for sex, birth weight (<1250 vs ≥1250 g) and hospital.
SETTING:
Five Australian tertiary hospitals from 2008 to 2013.
PARTICIPANTS:
626 of the 657 participants randomised between 2001 and 2005 were eligible to participate.
INTERVENTIONS:
High-DHA (≈1% total fatty acids) enteral feeds compared with standard-DHA (≈0.3% total fatty acids) from age 2-4 days until term CA.
PRIMARY OUTCOME:
Full Scale IQ of the Wechsler Abbreviated Scale of Intelligence (WASI) at 7 years CA. Prespecified subgroup analyses based on the randomisation strata (sex, birth weight) were conducted.
RESULTS:
604 (92% of the 657 originally randomised) consented to participate (291 high-DHA, 313 standard-DHA). To address missing data in the 604 consenting participants (22 for primary outcome), multiple imputation was performed. The Full Scale IQ was not significantly different between groups (high-DHA 98.3, SD 14.0, standard-DHA 98.5, SD 14.9; mean difference adjusted for sex, birthweight strata and hospital -0.3, 95% CI -2.9 to 2.2; p=0.79). There were no significant differences in any secondary outcomes. In prespecified subgroup analyses, there was a significant sex by treatment interaction on measures of parent-reported executive function and behaviour. Scores were within the normal range but girls receiving the high-DHA diet scored significantly higher (poorer outcome) compared with girls receiving the standard-DHA diet.
CONCLUSIONS:
Supplementing the diets of preterm infants with a DHA dose of approximately 1% total fatty acids from days 2-4 until term CA showed no evidence of benefit at 7 years' CA.
