which is when fresh information on astronomical objects is found in archive data and images that predates the actual discovery. As Stanley notes, for example, “Pluto was officially discovered in 1930, but astronomers digging through archives since then have found evidence of its discovery going far...
1997). A subtle gradation determines the relation between the two: if the decorator has less of an impact on a building’s structural identity, this is because to decorate implies a different relation to the identity of a building. Adorning and integrating objects within its...
As noted, scientists have known for years that there are large amounts of frozen water in the Moon’s polar regions. At the same time, however, scientists have held that the Moon’s interior must have depleted of water and other volatile compounds billions of years ago. This was based on...
On the hallway, “The intention was to create a strong first impression”, the designer notes, and the task was accomplished by the placement of a gorgeous Diamond Emerald Sideboard. Chosen by the designer and owners together, its sculptural, faceted shape defies convention and creates...

Versions Notes Abstract Many modern high-end vehicles exploit controllable damping solutions to enhance their adaptability to different road conditions and driving styles. Among these technologies, active dampers offer improved performance due to their four-quadrant operation in the torque–speed plane. In...
Versions Notes Abstract This study assesses the capability of Surface Quasi-Geostrophy (SQG) to reconstruct the three-dimensional (3D) dynamics in four critical areas of the Arctic Ocean: the Nordic, Barents, East Siberian, and Beaufort Seas. We first reconstruct the upper ocean dynamics from TOP...
Versions Notes Abstract Interior permanent-magnet synchronous machines (IPMSMs) are widely used as traction motors in electric drive-trains because of their high torque-per-ampere characteristics and potential for wide field-weakening operations to expand the constant-power range. This paper offers a ...
Versions Notes Abstract Natural sources of mercury, historical gold mining, and contemporary artisanal and small-scale gold mining (ASGM) activities have led to mercury contamination in Suriname. Our primary objective was to evaluate mercury levels in hair of women and children from interior villages ...
