New Zealand Observations during the Lunar Eclipse 1921 April 21

Variations in the sky brightness during a lunar eclipse

A total lunar eclipse is conjectured to have influence on the physical conditions of an environmental area, particularly on the brightness of the sky. The phenomenon might also be relevant on weather parameters change on Earth, such as temperature, humidity and pressure, though a straightforward correlation is not easy to establish. This work mainly aims at measuring the brightness of the sky a...

Lunar eclipse observations reveal anomalous thermal performance of Apollo reflectors

Laser ranging measurements during the total lunar eclipse on 2010 December 21 verify previously suspected thermal lensing in the retroreflectors left on the lunar surface by the Apollo astronauts. Signal levels during the eclipse far exceeded those historically seen at full moon, and varied over an order of magnitude as the eclipse progressed. These variations can be understood via a straightfo...

21 st New Zealand Phylogenomics Meeting

Critical Review , 21 April

This is a critical review of the paper “An Airway Tree-shape Model for Geodesic Airway Branch Labeling” written by Feragen et. al. [1]. This paper presents a method for airway branch labeling by computing geodesic deformations between mathematical airway tree-shape models. The authors claim that the labeling results are good taking the large variation in the training set into account. Even thou...
