Robust estimation of the carbon dioxide airborne fraction under measurement errors
Environmental Research CommunicationsThe carbon dioxide (CO _2 ) airborne fraction, the proportion of anthropogenic CO _2 emissions that remain in the atmosphere, is a critical metric for research on the carbon cycle and climate change.

Cultural and Chronological Complexes of the Beryozovaya Griva I Settlement in the Lower Kama Region
Археология евразийских степей, 2023 The article analyzes the materials of one of the multilayer settlement monuments of the Primeval period, located in the Lower Kama region – Beryozovaya Griva I settlement. The materials of the settlement trace back several stages of its functioning. The earliest stage belongs to the Late Neolithic.

American Museum Novitates, 2016 ABSTRACT Although Mesozoic fossils are quite common in the Gobi Desert of Central Asia, it is often difficult to correlate among different localities because of a dearth of rocks amenable to absolute dating. Specifically, correlating between the eastern Gobi Desert and more western localities has been challenging. Here we give a Santonian-Campanian age

Nano-droplets deposited in microarrays by femtosecond Ti:sapphire laser-induced forward transfer [PDF]
, 2006 The authors present the deposition of nanoscale droplets of Cr using femtosecond Ti:Sapphire Laser-Induced Forward Transfer. Deposits around 300 nm in diameter, significantly smaller than any previously reported, are obtained from a 30 nm thick source ...
