| 1 | 光学异常透射的微观理论显示文摘本文介绍了作者最近在《自然》杂志(Nature,2008,452:728—731)发表的一项解释光学异常透射的微观理论。该理论建立了描述异常透射的一个金属表面等离子体(sur-faceplasmonpolariton,SPP)模型,通过比较模型预言的结果和严格求解Maxwell方程组全矢量方法的数值计算结果,发现在可见光及近红外波段,该模型能够定量给出异常透射的所有主要特征,从而验证了该模型的有效性。由于模型中仅保留了SPP而忽略了其它金属表面波,因此能够单独考察SPP在异常透射中的贡献,有助于调和之前不同观点间的争论。同时,由于该模型将二维孔阵列分解为一维孔链的周期组合,然后综合考虑各孔链处SPP的激发及散射过程,因此能够从微观层面分析形成异常透射的物理原因,解释了传统模式展开方法中表面Bloch模式的物理根源,同时能够为相关器件的设计提供理论指导。 | 刘海涛 Philippe Lalanne | 2008 | 中国基础科学2008，10，3： | 21 |
| 2 | Hepatocellular carcinoma in viral and autoimmune liver diseases:Role of CD4+CD25+Foxp3+regulatory T cells in the immune microenvironment显示文摘More than 90%of cases of hepatocellular carcinoma(HCC)occurs in patients with cirrhosis,of which hepatitis B virus and hepatitis C virus are the leading causes,while the tumor less frequently arises in autoimmune liver diseases.Advances in understanding tumor immunity have led to a major shift in the treatment of HCC,with the emergence of immunotherapy where therapeutic agents are used to target immune cells rather than cancer cells.Regulatory T cells(Tregs)are the most abundant suppressive cells in the tumor microenvironment and their presence has been correlated with tumor progression,invasiveness,as well as metastasis.Tregs are characterized by the expression of the transcription factor Foxp3 and various mechanisms ranging from cell-to-cell contact to secretion of inhibitory molecules have been implicated in their function.Notably,Tregs amply express checkpoint molecules such as cytotoxic T lymphocyte-associated antigen 4 and programmed cell-death 1 receptor and therefore represent a direct target of immune checkpoint inhibitor(ICI)immunotherapy.Taking into consideration the critical role of Tregs in maintenance of immune homeostasis as well as avoidance of autoimmunity,it is plausible that targeting of Tregs by ICI immunotherapy results in the development of immune-related adverse events(irAEs).Since the use of ICI becomes common in oncology,with an increasing number of new ICI currently under clinical trials for cancer treatment,the occurrence of irAEs is expected to dramatically rise.Herein,we review the current literature focusing on the role of Tregs in HCC evolution taking into account their opposite etiological function in viral and autoimmune chronic liver disease,and we discuss their involvement in irAEs due to the new immunotherapies. | Alessandro Granito Luigi Muratori Claudine Lalanne Chiara Quarneti Silvia Ferri Marcello Guidi Marco Lenzi Paolo Muratori | 2021 | World Journal of Gastroenterology2021，27，22： | 11 |
| 3 | Cooperative interactions between nano-antennas in a high-Q cavity for unidirectional light sources显示文摘We analyse the resonant mode structure and local density of states in high-Q hybrid plasmonic-photonic resonators composed of dielectric microdisks hybridized with pairs of plasmon antennas that are systematically swept in position through the cavity mode.On the one hand,this system is a classical realization of the cooperative resonant dipole–dipole interaction through a cavity mode,as is evident through predicted and measured resonance linewidths and shifts.At the same time,our work introduces the notion of‘phased array’antenna physics into plasmonic-photonic resonators.We predict that one may construct large local density of states(LDOS)enhancements exceeding those given by a single antenna,which are‘chiral’in the sense of correlating with the unidirectional injection of fluorescence into the cavity.We report an experiment probing the resonances of silicon nitride microdisks decorated with aluminium antenna dimers.Measurements directly confirm the predicted cooperative effects of the coupled dipole antennas as a function of the antenna spacing on the hybrid mode quality factors and resonance conditions. | Kevin G.Cognee Hugo M.Doeleman Philippe Lalanne A.F.Koenderink | 2019 | Light(Science & Applications)2019，8，1： | 6 |
| 4 | Hydrogeochemical and multi-tracer investigations of arsenic-affected aquifers in semi-arid West Africa显示文摘The semi-arid Sahel regions ofWest Africa rely heavily on groundwater from shallow to moderately deep (<100 m b.g.l.) crystalline bedrock aquifers for drinking water production.Groundwater quality may be affected by high geogenic arsenic (As) concentrations (>10 μg/L) stemming from the oxidation of sulphide minerals (pyrite,arsenopyrite) in mineralised zones.These aquifers are still little investigated,especially concerning groundwater residence times and the influence of the annual monsoon season on groundwater chemistry.To gain insights on the temporal aspects of As contamination,we have used isotope tracers (noble gases,3H,stable water isotopes (2H,18O)) and performed hydrochemical analyses on groundwater abstracted from tube wells and dug wells in a small study area in southwestern Burkina Faso.Results revealed a great variability in groundwater properties (e.g.redox conditions,As concentrations,water level,residence time) over spatial scales of only a few hundred metres,characteristic of the highly heterogeneous fractured underground.Elevated As levels are found in oxic groundwater of circum-neutral pH and show little relation with any of the measured parameters.Arsenic concentrations are relatively stable over the course of the year,with little effect seen by the monsoon.Groundwater residence time does not seem to have an influence on As concentrations,as elevated As can be found both in groundwater with short (<50 a) and long (>10^3 a) residence times as indicated by 3He/4He ratios spanning three orders of magnitude.These results support the hypothesis that the proximity to mineralised zones is the most crucial factor controlling As concentrations in the observed redox/pH conditions.The existence of very old water portions with residence times >10^3 years already at depths of <50 m b.g.l.is a new finding for the shallow fractured bedrock aquifers of Burkina Faso,suggesting that overexploitation of these relatively low-yielding aquifers may be an issue in the future. | Anja Bretzler Lucien Stolze Julien Nikiema Franck Lalanne Elaheh Ghadiri Matthias S.
