Investigating The Potential Of Time-Varying Free Parameters In Equilibrium Shoreline Change Models Through Data Assimilation, Georgios Azorakos, Bruno Castelle, Déborah Idier, Vincent Marieu, Raimundo Ibaceta, Kristen D. Splinter, Stéphane Bertin, Gerd Masselink, Timothy Scott

School of Biological and Marine Sciences

Equilibrium shoreline change models with calibrated, time-invariant free parameters have demonstrated good skill in hindcasting shoreline evolution at sites dominated by cross-shore sediment transport. However, their performance can be biased by the specific conditions present during the calibration period. In this study, a dual parameter-state ensemble Kalman filter (EnKF) was applied to track non-stationarity in model free parameters at three sites along the west coast of Europe. Introducing time-varying parameters did not substantially improve performance relative to an already well-calibrated stationary model. Model skill improvement occurred mainly during the EnKF correction step, highlighting the potential of real-time data assimilation for …

The Rise And [?] Of Anti-Administrativism, Gary Lawson

BYU Law Review

Scholars have proclaimed the administrative state to be “Under Siege” or subject to a “Never-Ending Assault.” Was the election of President Donald Trump on November 5, 2024, the sixth, if not yet the seventh, day around the walls?

This seems an appropriate time to consider the present and future of opposition to the administrative state—something that has come to be dubbed “anti-administrativism.” The first task, as is usually the case when one seeks intellectual clarity, is to figure out what one is talking about. What is this “anti-administrativism”? Without knowing the answer to that seemingly simple question, one cannot accurately …

Innovation-Motivated Education (Ime): From “Trap Of Excellence” To “Fusion Of Exceptional”, Quanshui Zheng

Bulletin of Chinese Academy of Sciences (Chinese Version)

The “Needham Question” and “Tsien Hsue-shen’s Inquiry” jointly reveal a deep-seated structural contradiction—the “trap of excellence”: while traditional educational paradigms excel at mass-producing excellent talent that conforms to existing standards, they systemically suppress the emergence of exceptional geniuses capable of pioneering “new continents”. Confronted with the strategic goal of “building China into an education, science & technology, and talent powerhouse by 2035” and the transformative changes brought by AI technology, driving the reconstruction of educational paradigms and evaluation systems has become an urgent national strategic imperative. Based on sixteen years of practical exploration at Tsinghua University’s Tsien Excellence in Engineering …

Snow, Brittany L Morgan Bustamante, Natalie J. Kane, Rose Reynolds, Aidan Lee, Mark A. Hoffman, Theodore C. White, Justin V. Remais, Jennifer R. Head

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Where surveillance data are limited, nationally representative electronic health records allow for geographic, temporal, and demographic characterization of the fungal diseases blastomycosis and histoplasmosis.

METHODS: We identified incident blastomycosis and histoplasmosis cases from 2013 to 2023 within Oracle EHR Real-World Data, which comprises 1.6 billion healthcare encounters nationally. To characterize spatiotemporal incidence trends, we used generalized estimating equations weighted for nonrepresentativeness of electronic health record-reporting facilities. We computed standardized incidence rate ratios (sIRRs), which relay relative differences in standardized incidence rates between regions, race/ethnicity, gender, and age subgroups and the national population.

RESULTS: National incidence rates in 2023 were …
