    Urban Areas in Coastal Zones

    Get PDF
    [First Paragraph] Coastal cities have been subjected to extreme weather events since the onset of urbanization. Climatic change, in particular sea level rise, coupled with rapid urban development are amplifying the challenge of managing risks to coastal cities. Moreover, urban expansion and changes and intensification in land use further pressure sensitive coastal environments through pollution and habitat loss

    Ultra-high carbon fullerene-based spin-on-carbon hardmasks

    Fullerene-based spin-on-carbon enables very high carbon content, and shows very high thermal stability, and etch resistance approaching amorphous carbon. Here we describe the performance of the HM1300 fullerene SOC, including results using high temperature inert atmosphere curing. Ohnishi numbers below 1.44 are achieved (measured by elemental analysis) and etch performance improved over the standard bake. A new high carbon crosslinker, designed to link directly to the fullerene cage, and with a carbon content comparable to the fullerene (significantly higher than the previous crosslinker) is also introduced. The new crosslinker is designed to enhance both etch and thermal stability performance

    From Farm to Fork: growing a Scottish Food System that doesn't cost the Planet

    Our global food system is under immense pressure. Feeding a growing human population well while simultaneously delivering required climate, biodiversity and other key outcomes arguably represents the biggest challenge of our civilization in the twenty-first century. Here we discuss this growing challenge in the context of Scotland, its progress to date, its new target of “net zero” greenhouse gas emissions by 2045, and its potential to be an exemplar for well-integrated land use policy that delivers on multiple aims. We highlight the role of research in informing rural policy and landowner actions and stress the importance of social science in helping to ensure a sustainable net zero transition that takes full account of socioeconomic contexts and avoids the big potential pitfalls of ignoring local contexts

    Long-term effects of chronic light pollution on seasonal functions of European blackbirds (turdus merula)

    Light pollution is known to affect important biological functions of wild animals, including daily and annual cycles. However, knowledge about long-term effects of chronic exposure to artificial light at night is still very limited. Here we present data on reproductive physiology, molt and locomotor activity during two-year cycles of European blackbirds (Turdus merula) exposed to either dark nights or 0.3 lux at night. As expected, control birds kept under dark nights exhibited two regular testicular and testosterone cycles during the two-year experiment. Control urban birds developed testes faster than their control rural conspecifics. Conversely, while in the first year blackbirds exposed to light at night showed a normal but earlier gonadal cycle compared to control birds, during the second year the reproductive system did not develop at all: both testicular size and testosterone concentration were at baseline levels in all birds. In addition, molt sequence in light-treated birds was more irregular than in control birds in both years. Analysis of locomotor activity showed that birds were still synchronized to the underlying light-dark cycle. We suggest that the lack of reproductive activity and irregular molt progression were possibly the results of i) birds being stuck in a photorefractory state and/or ii) chronic stress. Our data show that chronic low intensities of light at night can dramatically affect the reproductive system. Future studies are needed in order to investigate if and how urban animals avoid such negative impact and to elucidate the physiological mechanisms behind these profound long-term effects of artificial light at night. Finally we call for collaboration between scientists and policy makers to limit the impact of light pollution on animals and ecosystems

    Differential Random Fault Attacks on certain CAESAR Stream Ciphers (Supplementary Material)

    Get PDF
    This document contains supplementary material to the paper with the same title available from the proceedings of the International Conference on Information Security and Cryptology (ICISC) 2019. In this supplementary material, we demonstrate that the random fault attack strategy described in the full paper can be applied to ciphers in the MORUS family, resulting in partial state recovery for these ciphers
