The Planetary Mass–Radius Relation and Its Dependence on Orbital Period as Measured by Transit Timing Variations and Radial Velocities [PDF]
, 2017 The two most common techniques for measuring planetary masses—the radial velocity (RV) and the transit timing variation (TTV) techniques—have been observed to yield systematically different masses for planets of similar radii.

Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 470-483, December 2022., 2022 In Yellowstone Lake, Wyoming, lake trout carcasses are used to suppress invasive lake trout embryos in an effort to conserve native Yellowstone cutthroat trout. Using a field experiment, we determined that carcass treatment had limited, non‐target effects on benthic invertebrates.

Dead Zones as Thermal Barriers to Rapid Planetary Migration in Protoplanetary Disks [PDF]
, 2010 Planetary migration in standard models of gaseous protoplanetary disks is known to be very rapid ($\sim 10^5$ years) jeopardizing the existence of planetary systems. We present a new mechanism for significantly slowing rapid planetary migration, discovered by means of radiative transfer calculations of the thermal structure of protoplanetary disks ...
