Out There No One Has a Right to Die
Bioethics, EarlyView.ABSTRACT The eventual goal of space exploration is to colonize exoplanets and their moons outside our solar system. This is a dangerous and immoral endeavour. The extraterrestrial life forms encountered would be hostile, vulnerable or both, and the descendants of the original pioneers would be involuntarily exposed to hazardous conditions and ...

Computing Skinning Weights via Convex Duality
Computer Graphics Forum, EarlyView.We present an alternate optimization method to compute bounded biharmonic skinning weights. Our method relies on a dual formulation, which can be optimized with a nonnegative linear least squares setup. Abstract We study the problem of optimising for skinning weights through the lens of convex duality.

Ecosystem Impacts of the Landing Obligation for Unwanted Catch in Thermaikos Gulf (Greece)
Fisheries Management and Ecology, EarlyView.ABSTRACT Discards by marine commercial fisheries have been an issue of major concern to the scientific community in recent years. We modeled the ecological and trophic consequences of a mandatory landing obligation (LO) regulated by the reformed Common Fisheries Policy [Regulation (EU) 1380/2013] on the Thermaikos Gulf ecosystem (northwestern Aegean ...
