Single-photon avalanche diodes(SPADs)are the most widespread commercial solution for single-photon counting in quantum key distribution ***,the secondary photon emission that arises from the avalanche of charge carriers that occurs during the detection of a photon may be exploited by an eavesdropper to gain information without inducing errors in the transmission *** this paper,we characterize such backflash light in gated InGaAs/InP SPADs and discuss its spectral and temporal characterization for different detector models and different operating *** qualitatively bound the maximum information leakage due to backflash light and propose solutions for preventing such leakage.

Is it possible that a measurement of a spin component of a spin-1/2 particle yields the value 100?In 1988 Aharonov,Albert and Vaidman argued that upon pre-and postselection of particular spin states,weakening the coupling of a standard measurement procedure ensures this paradoxical *** theoretical prediction,called weak value,was realised in numerous experiments2-9,but its meaning remains very controversialsince its"anomalous"nature,i.e.z the possibility to exceed the eigenvalue spectrum,as well as its"quantumness"are *** address these questions by presenting the first experiment measuring anomalous weak values with just a single click,without the need for statistical *** measurement uncertainty is significantly smaller than the gap between the measured weak value and the nearest *** clarifying the meaning of weak values,demonstrating their non-statistical,single-particle nature,this result represents a breakthrough in understanding the foundations of quantum measurement,showing unprecedented measurement capability for further applications of weak values to quantum photonics.

The efficiency of photo-electrocatalytic（PECa） devices for the production of solar fuels depends on several limiting factors such as light harvesting, charge recombination and mass transport diffusion. We analyse here how they influence the performances in PECa cells having a photo-anode based on Au-modified TiOnanotube（TNT） arrays, with the aim of developing design criteria to optimize the photo-anode and the PECa cell configuration for water photo-electrolysis（splitting） and ethanol photo-reforming *** TNT samples were prepared by controlled anodic oxidation of Ti foils and then decorated with gold nanoparticles using different techniques to enhance the visible light response through heterojunction and plasmonic effects. The activity tests were made in a gas-phase reactor, as well as in a PECa cell without applied bias. Results were analysed in terms of photo-generated current, Hproduction rate and photoconversion efficiency. Particularly, a solar-to-hydrogen efficiency of 0.83% and a Faradaic efficiency of 91%were obtained without adding sacrificial reagents.

在一项新的研究中，来自美国德州大学MD安德森癌症中心的研究人员利用患者源性肿瘤异种移植（patient—derived tumorxenograft,PDx）和模式小鼠开展一系列临床前实验，鉴定出一种门卫蛋白（gatekee Perprotein）阻止胰腺癌细胞转化为一种极具侵袭性的细胞类型，并且也发现剔除这种门卫蛋白的疗法能够阻止这些癌细胞。这些发现有助为携带这种进展迅速的治疗抵抗性的胰腺癌细胞亚群的患者开发出潜在的疗法。

针对当下历史建筑所面临的“冷冻式保护”和“推倒重来式更新”困境,探索如何在历史建筑的保护与更新中既延续“过去”的历史文脉又能适应“现时”的功能需求。引入语言学历时性与共时性的概念作为新视角和切入点,以意大利建筑修复代表人物马可·戴齐·巴戴斯齐的保护性修复思想及其实践作品为例,探究历时性与共时性思想在历史建筑干预中的作用及意义。该思想主张从时间与空间两个维度介入,可以兼顾历史延续与改造需求的问题,能够沉积历史建筑的文化底蕴并赋予历史建筑新的生命力。这种建筑干预理念是全面的、综合的,应用这一理念的干预手段是能够适用于我国历史建筑可持续性存续的有效策略。
