| 1 | Growing Operational Use of FY-3 Data in the ECMWF System显示文摘This paper reviews the data quality and impact of observations from the FY-3 satellite series used operationally in the ECMWF system. This includes data from the passive microwave radiometers MWHS-1, MWHS-2 and MWRI, as well as observations from the radio occultation receiver GNOS. Evaluations against background equivalents show that the quality of the observations is broadly comparable to that of similar instruments on other polar-orbiting satellites, even though biases for the passive microwave observations can be somewhat larger and more complex for some channels. An observing system experiment shows that the FY-3 instruments jointly contribute significantly to the forecast skill in the ECMWF system. Positive impact of up to 2% is seen for most variables out to the day-2 forecasts over hemispheric scales, with significant benefits for total column water vapor or for temperature and wind in the stratosphere out to day 4. | Niels BORMANN David DUNCAN Stephen ENGLISH Sean HEALY Katrin LONITZ Keyi CHEN Heather LAWRENCE Qifeng LU | 2021 | Advances in Atmospheric Sciences2021,38,8: | 3 |
| 2 | Assimilation of Feng-Yun-3B Satellite Microwave Humidity Sounder Data over Land显示文摘The ECMWF has been assimilating Feng-Yun-3B(FY-3B) satellite microwave humidity sounder(MWHS) data over ocean in an operational forecasting system since 24 September 2014. It is more difficult, however, to assimilate microwave observations over land and sea ice than over the open ocean due to higher uncertainties in land surface temperature, surface emissivity and less effective cloud screening. We compare approaches in which the emissivity is retrieved dynamically from MWHS channel 1 [150 GHz(vertical polarization)] with the use of an evolving emissivity atlas from 89 GHz observations from the MWHS onboard NOAA and EUMETSAT satellites. The assimilation of the additional data over land improves the fit of short-range forecasts to other observations, notably ATMS(Advanced Technology Microwave Sounder) humidity channels, and the forecast impacts are mainly neutral to slightly positive over the first five days. The forecast impacts are better in boreal summer and the Southern Hemisphere. These results suggest that the techniques tested allow for effective assimilation of MWHS/FY-3B data over land. | Keyi CHEN Niels BORMANN Stephen ENGLISH Jiang ZHU | 2018 | Advances in Atmospheric Sciences2018,35,3: | 2 |

| 6 | Identification of new genetic risk factors for prostate cancer显示文摘有证据,到前列腺癌症(PCa ) 的基因倾向的实质的部分可能由于被染色体宽的协会研究发现的更低的外显率基因。我们最近进行了如此的研究,染色体的七个新区域连接了到 PCa 风险被识别了。三这些 loci 包含候选人危险性基因:MSMB, LMTK2 和 KLK2/3。MSMB 和 KLK2/3 基因可能为 PCa 屏蔽,和 LMTK2 基因是有用的可能提供一个潜在的治疗学的目标。和从另外的组的结果,现在有 23 germline 被报导了的基因变体。这些结果有潜力被发展进基因测试。然而,我们认为测试出售到公众是早熟的,当 PCa 风险不能在这个阶段和要发展的适当屏蔽协议需要充分被评估。后续确认学习,以及学习探索基因侧面测试的心理含意,将重要在以前推出进保健。 | Michelle Guy Zsofia Kote-Jarai Graham G.

| 7 | Hepatitis E virus: Western Cape, South Africa显示文摘AIM To conduct a prospective assessment of anti-hepatitis E virus(HEV) Ig G seroprevalence in the Western Cape Province of South Africa in conjunction with evaluating risk factors for exposure.METHODS Consenting participants attending clinics and wards of Groote Schuur, Red Cross Children's Hospital and their affiliated teaching hospitals in Cape Town, South Africa, were sampled. Healthy adults attending blood donor clinics were also recruited. Patients with known liver disease were excluded and all major ethnic/race groups were included to broadly represent local demographics. Relevant demographic data was captured at the time of sampling using an interviewer-administered confidential questionnaire. Human immunodeficiency virus(HIV) status was self-disclosed. HEV Ig G testing was performed using the Wantai? assay.RESULTS HEV is endemic in the region with a seroprevalence of 27.9%(n = 324/1161) 95%CI: 25.3%-30.5%(21.9% when age-adjusted) with no significant differences between ethnic groups or HIV status. Seroprevalence in children is low but rapidly increases in early adulthood. With univariate analysis, age ≥ 30 years old, pork and bacon/ham consumption suggested risk. In the multivariate analysis, the highest risk factor for HEV Ig G seropositivity(OR = 7.679, 95%CI: 5.38-10.96, P < 0.001) was being 30 years or older followed by pork consumption(OR = 2.052, 95%CI: 1.39-3.03, P < 0.001). A recent clinical case demonstrates that HEV genotype 3 may be currently circulating in the Western Cape.CONCLUSION Hepatitis E seroprevalence was considerably higher than previously thought suggesting that hepatitis E warrants consideration in any patient presenting with an unexplained hepatitis in the Western Cape, irrespective of travel history, age or ethnicity. | Richie G Madden Sebastian Wallace Mark Sonderup Stephen Korsman Tawanda Chivese Bronwyn Gavine Aniefiok Edem Roxy Govender Nathan English Christy Kaiyamo Odelia Lutchman Annemiek A van der Eijk Suzan D Pas Glynn W Webb Joanne Palmer Elizabeth Goddard Sean Wasserman Harry R Dalton C Wendy Spearman | 2016 | World Journal of Gastroenterology2016,22,44: | 0 |
