When extracting the weak lensing shear signal, one may employ either locally normalized or globally normalized shear estimators. The former is the standard approach when estimating cluster masses, while the latter is the more common method among peak finding efforts. While both approaches have identical signal-to-noise in the weak lensing limit, it is possible that higher order corrections or s...

High-sensitivity receiver systems with near-ideal polarization sensitivity are highly desirable for development of millimeter and submillimeter radio astronomy. Multimoded bolometers provide a unique solution to achieve such sensitivity, for which hundreds of single-mode sensors would otherwise be required. The primary concern in employing such multimoded sensors for polarimetery is the control...

A new practice in systematics, “semaphoront” coding, treats developmental stages as terminals, and it derives from Hennig’s concept of the same name. Semaphoront coding has been implemented recently by Lamsdell and Selden (BMC Evol. Biol., 2013, 13:98) and Wolfe and Hegna (Cladistics, 2014, 30:366) in an effort to understand the relationships of fossil taxa of unknown developmental stage. We su...
