  • Population-Aware Sequential Flight Path Optimisation for Low-Noise and Low-Fuel Consumption Departure Trajectory

    Population-Aware Sequential Flight Path Optimisation for Low-Noise and Low-Fuel Consumption Departure Trajectory

    With the increase in air traffic over the past decades, the reduction of aircraft noise is one of the major challenges facing stakeholders. Flight operating conditions that decrease noise may possibly increase the fuel consumption of aircraft, which is an important factor in airline cost management. In this paper, we propose a methodology to support flight path planning with the aim of optimising both perceived noise and fuel consumption…

  • Blood-Based miRNA Tests: A Promising Tool for the Early Detection of Multiple Types of Cancer

    Blood-Based miRNA Tests: A Promising Tool for the Early Detection of Multiple Types of Cancer

    Cancer is a major global health problem. According to the World Health Organisation (WHO), there was an estimated 19.3
    million new cancer cases and 10 million cancer-related deaths worldwide in 2020, representing an increase of 28% in
    the global cancer burden since 2010 (WHO, 2020). One of the main challenges in cancer treatment is late diagnosis and
    its consequential negative impact on patient outcomes. According to the American Cancer Society, the 5-year survival
    rate for breast cancer is 90% when detected at an early stage, compared to 15% when detected at a late stage (American
    Cancer Society, n.d.)….

  • 基於血液的 miRNA 測試:一種有望能及早檢測出多種癌症的工具

    基於血液的 miRNA 測試:一種有望能及早檢測出多種癌症的工具

    癌症是一個威脅全球的重大健康問題。根據世界衛生組織(WHO)的估計,2020年全球新增癌症病例約為1,930萬宗,與癌症相關的死亡個案為1,000萬宗,這代表自2010年以來全球癌症負擔增加了28%(WHO,2020年)。
    延遲診斷是治療癌症的其中一項最大挑戰,並因此會減低患者的治療效果。根據美國癌症協會的數據顯示,乳癌如能在早期階段發現,5年存活率達90%;然而晚期診斷的存活率卻只有15%(美國癌症協會,日期不詳)….

    Haber Process: More Than Just Nitrogen and Ammonia

    Have you ever doubted how the agricultural supply manages to feed the exponentially growing world population? One of the keys is to provide nitrogen, an essential nutrient for good yields, through the use of nitrogenous fertilizers. The question then becomes: Where does all that nitrogen come from?….
