Depth‐Dependence Changes in Soil Stoichiometry in China's Croplands Over the Past Four Decades

open access: yesAdvanced Science, EarlyView.
This study reveals depth‐dependent changes in soil C:N:P ratios across Chinese croplands over four decades. Changes in stoichiometry vary markedly between topsoil and subsoil, with initial soil C:N:P ratios playing a key role in determining their trajectories.

Tribal Court Jurisdiction and Public Law 280: What Role for Tribal Courts in Alaska [PDF]

open access: yes, 1993
GPS data from Challenging Mini-satellite Payload (CHAMP) is used for its orbit determination for the epoch day of January 1st 2002.  The orbit of CHAMP is computed from the GPS data and ionospheric effects are removed by frequency combination.

Correlation of Fermi photons with high-frequency radio giant pulses from the Crab pulsar [PDF]

open access: yes, 2011
To constrain the giant pulse (GP) emission mechanism and test the model of Lyutikov (2007) for GP emission, we have carried out a campaign of simultaneous observations of the Crab pulsar at gamma-ray (Fermi) and radio (Green Bank Telescope) wavelengths ...

Comprehensive Genetic Map of Muscle Lipidome Reveals Novel Insights Into Flavor Variation in Ruminant Meat

open access: yesAdvanced Science, EarlyView.
Ruminant meat is widely appreciated for its distinctive flavor. Lipids play a central role in influencing meat flavor, yet their genetic and biochemical basis remains largely unexplored. Here, a comprehensive lipid genetic map of sheep muscle is constructed and 20 candidate genes potentially modulating lipid levels are identified to provide a roadmap ...

Height determination using GPS data, local geoid and global geopotential models [PDF]

open access: yes, 1995
Orthometric heights are normally derived using the spirit levelling. This requires the spirit level equipment to be set up from point 10 point along a levelling line which is a time consuming and tedious task.

Stage‐Resolved Phosphoproteomic Landscape of Mouse Spermiogenesis Reveals Key Kinase Signaling in Sperm Morphogenesis

open access: yesAdvanced Science, EarlyView.
The quantitative proteomic and phosphoproteomic profiling reveals dynamic phosphorylation regulation of sperm morphogenesis. Kinase‐substrate phosphorylation network and phosphorylation module analysis, followed by in vivo knockdown and knockout analysis, identify TTBK2 and CSNK1G1 as key regulators of morphogenesis, including head, flagellar, and ...
