A note on multiple imputation for method of moments estimation
No full textMultiple imputation is widely used for estimation in situations where there are missing data. Rubin (1987) provided an easily applicable formula for multiple imputation variance estimation, but its validity requires the congeniality condition of Meng (1994), which may not be satisfied for method of moments estimation. We give the asymptotic bias of Rubin's variance estimator when method of moments estimation is used in the complete-sample analysis for each imputed dataset. A new variance estimator based on over-imputation is proposed to provide asymptotically valid inference in this case.This is a pre-copyedited, author-produced PDF of an article accepted for publication in Biometrika following peer review.

Airfoil noise reductions through leading edge serrations
No full textThis paper provides an experimental investigation into the use of leading edge (LE) serrations as a means of reducing the broadband noise generated due to the interaction between the aerofoil’s LE and impinging turbulence. Experiments are performed on a flat plate in an open jet wind tunnel. Grids are used to generate isotropic homogeneous turbulence. The leading edge serrations are in the form of sinusoidal profiles of wavelengths, ?, and amplitudes, 2h. The frequency and amplitude characteristics are studied in detail in order to understand the effect of LE serrations on noise reduction characteristics and are compared with straight edge baseline flat plates. Noise reductions are found to be insignificant at low frequencies but significant in the mid frequency range (500 Hz–8 kHz) for all the cases studied. The flat plate results are also compared to the noise reductions obtained on a serrated NACA-65 aerofoil with the same serration profile. Noise reductions are found to be significantly higher for the flat plates with a maximum noise reduction of around 9 dB compared with about 7 dB for the aerofoil. In general, it is observed that the sound power reduction level (?PWL) is sensitive to the amplitude, 2h of the LE serrations but less sensitive to the serration wavelength, ?. Thus, this paper sufficiently demonstrates that the LE amplitude acts as a key parameter for enhancing the noise reduction levels in flat plates and aerofoils
Kim Gordon - no icon
No full textAs cofounder of legendary rock band Sonic Youth, best-selling author, and celebrated artist, Kim Gordon is one of the most singular and influential figures of the modern era. This personally curated scrapbook is an edgy and evocative portrait of Gordon s life, art, and style. Spanning from her childhood on Californian surf beaches in the 60s and 70s to New York s downtown art and music scene in the 80s and 90s where Sonic Youth was born. Through unpublished personal photographs, magazine and newspaper clippings, fashion editorials, and advertising campaigns, interspersed with Gordon s song lyrics, writings, artworks, private objects, and ephemera, this book demonstrates how Kim Gordon has been a role model for generations of women and me

All-optical TDM data demultiplexing at 80 Gbit/s with significant timing jitter tolerance using a fiber Bragg grating based rectangular pulse switching technology
No full textWe demonstrate the use of fiber Bragg grating based pulse-shaping technology to provide timing jitter tolerant data demultiplexing in an 80 Gb/s all-optical time division multiplexing (OTDM) system. Error-free demultiplexing operation is achieved with ~6 ps timing jitter tolerance using superstructured fiber Bragg grating based 1.7 ps soliton to 10 ps rectangular pulse conversion at the switching pulse input to a nonlinear optical loop mirror (NOLM) demultiplexer comprising highly nonlinear dispersion shifted fiber (HNLF). A 2-dB power-penalty improvement is obtained compared to demultiplexing without the pulse-shaping grating. <br/
Seismic travel-time data from: Illuminating structural variability of the East Aleutian plate interface from local and teleseismic P-to-S converted waves
No full textPlease cite as: Kiara A. Daly, Geoffrey A. Abers, Michael E. Mann, Guanning Pang, Doyeon Kim. (2025) Seismic travel-time data from: Illuminating structural variability of the East Aleutian plate interface from local and teleseismic P-to-S converted waves. [dataset] Cornell University Library eCommons Repository. https://doi.org/10.7298/sjdk-8272These files contain picked arrival times and file descriptions for the P-to-S conversions as described in Daly et al., Illuminating structural variability of the East Aleutian plate interface from local and teleseismic P-to-S converted waves, J. Geophys. Res., 2025. The observations are travel times for local earthquakes to local stations where mode-converted secondary arrivals were observed, explained as P-to-S (PS) conversions. Those conversions appear as strong S-polarized arrivals between the P and S phases, for earthquakes generally more than 40 km deep and paths of several tens to a couple hundred kilometers. The conversions take place near the top of the subducting Pacific Plate, so form evidence for plate structure and geometry. That publication documents the methodology and results; these data are used to make Figures 3, 4, 7, 8 and 11. Earthquake locations are from the "AACSE" dataset described in Ruppert et al. (2023), and station locations match those in the Supplemental Tables of the published paper.This study supported by the U.S. National Science Foundation, grant OCE-1949130
