Comparison of Decadal Trends among Total Solar Irradiance Composites of Satellite Observations

open access: yesAdvances in Astronomy, 2019
We present a new analysis of the two-decade-old controversy over interpretation of satellite observations of total solar irradiance (TSI) since 1978 and the implications of our findings for TSI as a driver of climate change.

Air exposure test in Colossoma macropomum juveniles maintained in water at suboptimal temperature: Physiological, metabolic and oxidative stress responses

open access: yesJournal of Fish Biology, EarlyView.
Abstract This study evaluated the physiological, metabolic and oxidative responses of Colossoma macropomum subjected to air exposure when maintained in water at suboptimal temperature (23°C). A total of 54 fish (81.33 ± 11.90 g) were distributed into nine tanks (6 fish per tank). For the air exposure test, 24 animals were exposed for 30 min and another

Brightness Temperature Sensitivity to Whitecap Fraction at Millimeter Wavelengths

open access: yesRemote Sensing, 2019
Accurate representation of the ocean-atmosphere coupling in weather, wave and climate models requires reliable estimates of air-sea surface fluxes of momentum, heat and mass.

Tree growth response and adaptation to climate change and climate extremes: From canopy to stem

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review synthesizes the responses and adaptations of tree growth, including canopy phenology, intra‐annual wood formation dynamics, and annual stem growth, to climate change and climate extremes. It highlights key knowledge gaps for future research to support sustainable forest management and enhance forest carbon storage under ongoing climate ...

Radiometer

open access: yes, 1912
A radiometer is a device for measuring the radiant flux (power) of electromagnetic radiation. William W. Coblentz of the National Bureau of Standards used this radiometer to produce a very important set of papers in which he verified experimentally the ...

Overnight Dynamics of Ventricular Cerebrospinal Fluid Amyloid‐Beta, Lactate and Hypocretin in Patients With Hydrocephalus: A Pilot Study

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT This pilot observational study evaluated whether frequent overnight sampling of ventricular cerebrospinal fluid could clarify how sleep, hypocretin and lactate relate to amyloid‐β42 dynamics in adults with hydrocephalus. Seven participants underwent hourly ventricular cerebrospinal fluid sampling from early evening to late morning during ...

Errors Analysis and Improvement on Measurement Method for Microwave/Millimeter-Wave Emissivity of Small Targets by Radiometer

open access: yesIEEE Access, 2019
When using traditional methods to measure the microwave/millimeter-wave emissivity of small targets, errors arise due to that the antenna's main lobe and side lobe cannot be completely covered by the target.

Subnational Border Reforms and Economic Activity in Africa

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT Using GIS methods, we identify territories in Africa affected by subnational border reforms between 1992 and 2013. Descriptive statistics reveal that these territories differed from other African regions across several key dimensions. For example, these territories were more populous and exhibited greater ethnic diversity.
