Resolving the Super-Earth/Gas Giant Connection in Stellar Mass and Metallicity

The Astrophysical Journal Letters
The observed correlation between inner super-Earths (SE) and outer gas giants (GG) places strong constraints on formation theories. Building on previous work, M. L. Bryan & E. J.

Interpreting How Neural Networks Infer Scatterer Geometry from Echolocation Echoes

Advanced Intelligent Systems, EarlyView.
Neural networks enable echolocation‐based shape classification but remain difficult to interpret due to their black‐box nature. This work presents a feature‐importance metric to uncover the echo regions driving decisions in shape‐specialized networks.

Three Thousand Motion-confirmed L and T Dwarf Candidates from the Backyard Worlds: Planet 9 Citizen Science Project

The Astronomical Journal
The Backyard Worlds: Planet 9 citizen science project uses data from the Wide-field Infrared Survey Explorer to detect infrared objects with significant motion. In this work, we present the majority of the L and T dwarf candidates discovered through this

Food inflation pass‐through from agricultural imports in a small open economy

American Journal of Agricultural Economics, EarlyView.
Abstract This paper develops a new framework for quantifying cost pass‐through in a small open economy by estimating firm‐level markup responses to agricultural import price shocks. We show theoretically that markup adjustments depend on firms' reliance on imported inputs and demand curvature, generating heterogeneous inflationary effects across firm ...

Disentangling auroral-, cloud-, and magnetic spot-driven variability in three early L dwarfs with HST/WFC3

Astronomy & Astrophysics
Variability monitoring provides unparalleled insights into the atmospheric processes of brown dwarfs and directly imaged exoplanets. Inhomogeneous clouds, aurorae, and magnetic spots have all been postulated as potential drivers of variability.

Infrared Spectroscopy of Brown Dwarfs: the onset of methane absorption in L dwarfs and the L/T transition

, 2001
We present infrared spectra of brown dwarfs with spectral types from mid-L to T. The 0.9-2.5 $μ$m spectra of three dwarfs found by the Sloan Digital Sky Survey contain absorption bands of both methane and carbon monoxide and bridge the gap between late L and previously observed T dwarfs.

Clinically Relevant Bleeding in Individuals With Cancer: Insights From a Nationwide Cohort Study

American Journal of Hematology, EarlyView.
ABSTRACT Cancer care is often complicated by coagulopathy leading to thrombosis and bleeding. While venous thromboembolism (VTE) has been extensively studied, bleeding remains an underestimated threat. To address this knowledge gap, we leveraged the Epic Cosmos database to determine the impact of cancer‐associated clinically relevant bleeding (CRB) in ...
