\n Mapping Urban Forest Structure Across Five U.S. Cities <\/a><\/h3>\n <\/div>\n\n \n

\n Urban forests provide critical ecosystem services, from stormwater runoff mitigation and heat island mitigation to biodiversity support and public health benefits, yet their structural composition varies enormously across and within cities. Understanding this variation is essential for evidence-based urban forest management.\r\nThis study applies a multi-scale principal components analysis (PCA) framework to census-tract-level urban forest inventory data across five U.S. cities: Washington DC, New York City, Columbus (OH), Minneapolis (MN), and Seattle (WA), representing a combined sample of 3,084 tracts. Preliminary global PCA results suggests that canopy extent and treediversity represent a shared dimension of urban forest quality. Marked structural differences across cities further indicate that no single management benchmark is universally applicable. Spatially constrained PCA (sPCA) and geographically weighted PCA (GWPCA) (in progress) will characterize the degree to which these structural gradients are spatially clustered and identify neighborhoods where local forest composition diverges from citywide patterns. Findings will inform targeted urban reforestation priorities and support planners in identifying underserved areas where strategic investment.\r\n <\/div>\n <\/div> \n <\/div>\n <\/div>\n <\/article>\n \n

\n Obsessed by a Dream: Rolf Wider\u00f8e - History and Future of Accelerator Technology in the Context of a Giant <\/a><\/h3>\n <\/div>\n\n \n

\n 2027 marks the 100th anniversary of the invention of the first high-frequency linear accelerator (LINAC), built in Aachen. In 1927, Rolf Wider\u00f8e\u2019s 27-page doctoral thesis opened new windows for science with his description of the LINAC and of a circular accelerator he had already invented in 1923 at the age of 21. \r\n\r\n\r\nThe lecture begins by exploring the fascinating but tragic life of a man and his family driven by science and progress. During World War II, Dr. Wider\u00f8e was faced with a moral dilemma that is still relevant for many scientists today and may be even more pressing now. It also determined much of his fate. As we follow Rolf Wider\u00f8e through the arc of the 20th century, the full breadth of accelerator applications up to the present day comes into view. For more than a century, technical facilities that accelerate subatomic particles to ever higher energies have been an integral part of science and research, as well as of medical and industrial applications. The most modern applications repeatedly allow quantum leaps in science, which are discussed towards the end of the lecture. <\/div>\n <\/div> \n <\/div>\n <\/div>\n <\/article>\n \n
