1Generating optical orbital angular momentum at visible wavelengths using a plasmonic metasurface显示文摘Light beams with a helical phase-front possess orbital angular momentum along their direction of propagation in addition to the spin angular momentum that describes their polarisation.Until recently,it was thought that these two‘rotational’motions of light were largely independent and could not be coupled during light–matter interactions.However,it is now known that interactions with carefully designed complex media can result in spin-to-orbit coupling,where a change of the spin angular momentum will modify the orbital angular momentum and vice versa.In this work,we propose and demonstrate that the birefringence of plasmonic nanostructures can be wielded to transform circularly polarised light into light carrying orbital angular momentum.A device operating at visible wavelengths is designed from a space-variant array of subwavelength plasmonic nano-antennas.Experiment confirms that circularly polarised light transmitted through the device is imbued with orbital angular momentum of 62'(with conversion efficiency of at least 1%).This technology paves the way towards ultrathin orbital angular momentum generators that could be integrated into applications for spectroscopy,nanoscale sensing and classical or quantum communications using integrated photonic devices.Ebrahim Karimi Sebastian A Schulz Israel De Leon Hammam Qassim Jeremy Upham Robert W Boyd 2014Light(Science & Applications)2014,3,1:39

3National Forest Inventories capture the multifunctionality of managed forests in Germany显示文摘Background:Forests perform various important ecosystem functions that contribute to ecosystem services.In many parts of the world,forest management has shifted from a focus on timber production to multi-purpose forestry,combining timber production with the supply of other forest ecosystem services.However,it is unclear which forest types provide which ecosystem services and to what extent forests primarily managed for timber already supply multiple ecosystem services.Based on a comprehensive dataset collected across 150 forest plots in three regions differing in management intensity and species composition,we develop models to predict the potential supply of 13 ecosystem services.We use those models to assess the level of multifunctionality of managed forests at the national level using national forest inventory data.Results:Looking at the potential supply of ecosystem services,we found trade-offs(e.g.between both bark beetle control or dung decomposition and both productivity or soil carbon stocks)as well as synergies(e.g.for temperature regulation,carbon storage and culturally interesting plants)across the 53 most dominant forest types in Germany.No single forest type provided all ecosystem services equally.Some ecosystem services showed comparable levels across forest types(e.g.decomposition or richness of saprotrophs),while others varied strongly,depending on forest structural attributes(e.g.phosphorous availability or cover of edible plants)or tree species composition(e.g.potential nitrification activity).Variability in potential supply of ecosystem services was only to a lesser extent driven by environmental conditions.However,the geographic variation in ecosystem function supply across Germany was closely linked with the distribution of main tree species.Conclusions:Our results show that forest multifunctionality is limited to subsets of ecosystem services.The importance of tree species composition highlights that a lack of multifunctionality at the stand level can be compensated by managing forests at the landscape level,when stands of complementary forest types are combined.These results imply that multi-purpose forestry should be based on a variety of forest types requiring coordinated planning across larger spatial scales.Nadja K.Simons María R.Felipe-Lucia Peter Schall Christian Ammer Jürgen Bauhus Nico Blüthgen Steffen Boch François Buscot Markus Fischer Kezia Goldmann Martin M.Gossner Falk Hänsel Kirsten Jung Peter Manning Thomas Nauss Yvonne Oelmann Rodica Pena Andrea Polle Swen C.Renner Michael Schloter Ingo Schöning Ernst-Detlef Schulze Emily F.Solly Elisabeth Sorkau Barbara Stempfhuber Tesfaye Wubet Jörg Müller Sebastian Seibold Wolfgang W.Weisser 2021Forest Ecosystems2021,8,1:2

13Intraprocedural gastric juice analysis as compared to rapid urease test for real-time detection of Helicobacter pylori显示文摘BACKGROUND Endofaster is an innovative technology that can be combined with upper gastrointestinal endoscopy(UGE)to perform gastric juice analysis and real-time detection of Helicobacter pylori(H.pylori).AIM To assess the diagnostic performance of this technology and its impact on the management of H.pylori in the real-life clinical setting.METHODS Patients undergoing routine UGE were prospectively recruited.Biopsies were taken to assess gastric histology according to the updated Sydney system and for rapid urease test(RUT).Gastric juice sampling and analysis was performed using the Endofaster,and the diagnosis of H.pylori was based on real-time ammonium measurements.Histological detection of H.pylori served as the diagnostic gold standard for comparing Endofaster-based H.pylori diagnosis with RUT-based H.pylori detection.RESULTS A total of 198 patients were prospectively enrolled in an H.pylori diagnostic study by Endofasterbased gastric juice analysis(EGJA)during the UGE.Biopsies for RUT and histological assessment were performed on 161 patients(82 men and 79 women,mean age 54.8±19.2 years).H.pylori infection was detected by histology in 47(29.2%)patients.Overall,the sensitivity,specificity,accuracy,positive predictive value,and negative predictive value(NPV)for H.pylori diagnosis by EGJA were 91.5%,93.0%,92.6%,84.3%,and 96.4%,respectively.In patients on treatment with proton pump inhibitors,diagnostic sensitivity was reduced by 27.3%,while specificity and NPV were unaffected.EGJA and RUT were comparable in diagnostic performance and highly concordant in H.pylori detection(κ-value=0.85).CONCLUSION Endofaster allows for rapid and highly accurate detection of H.pylori during gastroscopy.This may guide taking additional biopsies for antibiotic susceptibility testing during the same procedure and then selecting an individually tailored eradication regimen.Riccardo Vasapolli Florent Ailloud Sebastian Suerbaum Jens Neumann Nadine Koch Lukas Macke Jörg Schirra Julia Mayerle Peter Malfertheiner Christian Schulz 2023World Journal of Gastroenterology2023,29,10:1
14Delta variant(B.1.617.2)sublineages do not show increased neutralization resistance显示文摘The emergence of SARS-CoV-2 variants threatens efforts to control the COVID-19 pandemic.At present,the global spread of the Delta(B.1.617.2)variant is responsible for a rapid increase in COVID-19 cases and hospitalizations in many countries.The variant evades neutralizing antibodies and is believed to be more transmissible and pathogenic[1,2,3,4].Prerna Arora Amy Kempf Inga Nehlmeier Luise Graichen Anzhalika Sidarovich Martin S.Winkler Sebastian Schulz Hans-Martin Jäck Metodi V.Stankov Georg M.N.Behrens Stefan Pöhlmann Markus Hoffmann 2021Cellular & Molecular Immunology2021,18,11:1

16Efficient antibody evasion but reduced ACE2 binding by the emerging SARS-CoV-2 variant B.1.640.2显示文摘The SARS-CoV-2 spike(S)protein engages ACE2 for cell entry,and the S protein/ACE2 interface is an important target for neutralizing antibodies.In the course of the COVID-19 pandemic,SARS-CoV-2 variants have emerged that harbor mutations in the S protein,which confer neutralization resistance and allow viral spread in immunologically nonnaive populations.The most prominent example is the highly mutated Omicron variant,which infects convalescent or vaccinated individuals with unprecedented efficiency[1,2].Prerna Arora Amy Kempf Inga Nehlmeier Luise Graichen Sebastian Schulz Anne Cossmann Alexandra Dopfer-Jablonka Martin S.Winkler Hans-Martin Jäck Georg M.N.Behrens Stefan Pöhlmann Markus Hoffmann 2022Cellular & Molecular Immunology2022,19,9:0
17The spike protein of SARS-CoV-2 variant A.30 is heavily mutated and evades vaccine-induced antibodies with high efficiency显示文摘The COVID-19 pandemic,caused by SARS-CoV-2,continues to rage in many countries,straining health systems and economies.Vaccines protect against severe disease and death and are considered central to ending the pandemic.COVID-19 vaccines(and SARS-CoV-2 infection)elicit antibodies that are directed against the viral spike(S)protein and neutralize the virus.However,the emergence of SARS-CoV-2 variants with S protein mutations that confer resistance to neutralization might compromise vaccine efficacy[1].Prerna Arora Cheila Rocha Amy Kempf Inga Nehlmeier Luise Graichen Martin S.Winkler Martin Lier Sebastian Schulz Hans-Martin Jäck Anne Cossmann Metodi V.Stankov Georg M.N.Behrens Stefan Pöhlmann Markus Hoffmann 2021Cellular & Molecular Immunology2021,18,12:0

19No evidence for increased cell entry or antibody evasion by Delta sublineage AY.4.2显示文摘Since the beginning of the COVID-19 pandemic,multiple SARS-CoV-2 variants have emerged.While some variants spread only locally,others,referred to as variants of concern,disseminated globally and became drivers of the pandemic.All SARS-CoV-2 variants harbor mutations relative to the virus circulating early in the pandemic,and mutations in the viral spike(S)protein are considered of particular relevance since the S protein mediates host cell entry and constitutes the key target of the neutralizing antibody response.As a consequence,mutations in the S protein may increase SARS-CoV-2 infectivity and enable its evasion of neutralizing antibodies.Furthermore,mutations in the S protein can modulate viral transmissibility and pathogenicity.Prerna Arora Amy Kempf Inga Nehlmeier Luise Graichen Martin S.Winkler Martin Lier Sebastian Schulz Hans-Martin Jäck Stefan Pöhlmann Markus Hoffmann 2022Cellular & Molecular Immunology2022,19,3:0
20First Record of the Gekkonid Genus Cnemaspis Strauch, 1887 from Gunung Mulu National Park, Northern Sarawak, East Malaysia may Represent an Undescribed Species显示文摘We provide confirmed photographic evidence for the previously overlooked occurrence of the polyphyletic Asian gecko genus Cnemaspis from Gunung Mulu National Park, the world-renowned UNESCO natural heritage site in northern Sarawak, East Malaysia. This new record from Sarawak province represents a remarkable range extension for Cnemaspis cf. kendallii by 550 km to the northeast and denotes the most northern occurrence of the genus in Borneo. Our new finding makes it very likely that these gekkonid lizards also inhabit appropriate limestone karst habitats in adjacent Sabah, Brunei, and Kalimantan. Given the visible differences in the Mulu specimen compared to those from the remaining distribution range on Borneo and the Malaysian Peninsula together with the fact that numerous Cnemaspis species are restricted to small areas, it seems plausible that another undescribed, rather cryptic and possibly locally endemic Bornean species is involved. Lastly, the new record contributes to the importance of the Mulu National Park as a major conservation area in East Malaysia of international concerns.André KOCH Sebastian SCHULZ 2014Asian Herpetological Research2014,5,3:0
