  1. This conference paper provides an update on the Early Research Scholars Program (ERSP) background, structure, and implementation at the University of Illinois Chicago (UIC), developed at the University of California San Diego and funded by the National Science Foundation Improving Undergraduate STEM Education program. The program aims to support retention of students from marginalized backgrounds in the fields of computing as well as electrical and computer engineering. This paper provides program updates, including data from the 2022-2023 academic year and preliminary results from a reflection study that began in spring 2020. The reflection study examined the impact of the ERSP on a student's computing and engineering identity development based on student reflection responses. In this paper, we also discuss student demographics, retention rates, and changes made to the program's curriculum at UIC. The evaluation results from the last three years of the program are also shared, which show how students are impacted by the program, as well as areas for improvement. Preliminary results show that the program has positively impacted students' computing or engineering identity development for at least three identity dimensions: recognition, competence, and community.

  4. Abstract

    Sea‐level rise and associated flood hazards pose severe risks to the millions of people globally living in coastal zones. Models representing coastal adaptation and impacts are important tools to inform the design of strategies to manage these risks. Representing the often deep uncertainties influencing these risks poses nontrivial challenges. A common uncertainty characterization approach is to use a few benchmark cases to represent the range and relative probabilities of the set of possible outcomes. This has been done in coastal adaptation studies, for example, by using low, moderate, and high percentiles of an input of interest, like sea‐level changes. A key consideration is how this simplified characterization of uncertainty influences the distributions of estimated coastal impacts. Here, we show that using only a few benchmark percentiles to represent uncertainty in future sea‐level change can lead to overconfident projections and underestimate high‐end risks as compared to using full ensembles for sea‐level change and socioeconomic parametric uncertainties. When uncertainty in future sea level is characterized by low, moderate, and high percentiles of global mean sea‐level rise, estimates of high‐end (95th percentile) damages are underestimated by between 18% (SSP1‐2.6) and 46% (SSP5‐8.5). Additionally, using the 5th and 95th percentiles of sea‐level scenarios underestimates the 5%–95% width of the distribution of adaptation costs by a factor ranging from about two to four, depending on SSP‐RCP pathway. The resulting underestimation of the uncertainty range in adaptation costs can bias adaptation and mitigation decision‐making.

  8. Abstract

    A description is presented of the algorithms used to reconstruct energy deposited in the CMS hadron calorimeter during Run 2 (2015–2018) of the LHC. During Run 2, the characteristic bunch-crossing spacing for proton-proton collisions was 25 ns, which resulted in overlapping signals from adjacent crossings. The energy corresponding to a particular bunch crossing of interest is estimated using the known pulse shapes of energy depositions in the calorimeter, which are measured as functions of both energy and time. A variety of algorithms were developed to mitigate the effects of adjacent bunch crossings on local energy reconstruction in the hadron calorimeter in Run 2, and their performance is compared.
