High‐Temperature Magnetic Field Mapping Using a Single‐Crystal Diamond MEMS Resonator Array

open access: yesAdvanced Science, EarlyView.
A single‐crystal diamond MEMS resonator array enables magnetic‐field reconstruction with millisecond response, nanotesla level magnetic noise, and stable operation up to 573 K. Two‐ and three‐dimensional magnetic field mapping are demonstrated using ΔEeffect sensing, highlighting the potential of diamond MEMS technology for hightemperature magnetic ...

Cross-calibration between MWRI and AMSR2 to improve consistency of snow depth products

open access: yesResearch in Cold and Arid Regions
The Microwave Radiation Imager (MWRI), boarded on the FY-3 series satellites: FY-3B, FY-3C, and FY-3D, is the first satellite-based microwave radiometer in China, commencing passive microwave brightness temperature data acquisition since 2010.

Application of a coupled microwave, energy and water transfer model to relate passive microwave emission from bare soils to near-surface water content and evaporation [PDF]

open access: yesHydrology and Earth System Sciences, 1999
The paper examines the stability of the relation between microwave emission from the soil and the average near-surface water content in the case of relatively smooth, bare soils, and then considers the extent to which microwave radiometry can be used to ...

Intercalibration of Microwave Radiometer Brightness Temperatures for the Global Precipitation Measurement Mission

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2013
A technique for comparing spaceborne microwave radiometer brightness temperatures (Tb) is described in the context of the upcoming National Aeronautics and Space Administration Global Precipitation Measurement (GPM) mission. The GPM mission strategy is to measure precipitation globally with high temporal resolution by using a constellation of satellite

Validation of brightness and physical temperature from two scanning microwave radiometers in the 60 GHz O2 band using radiosonde measurements [PDF]

open access: yes, 2016
In this paper, we address the assessment of the tropospheric performance of a new temperature radiometer (TEMPERA) at 60 GHz. With this goal, an intercomparison campaign was carried out at the aerological station of MeteoSwiss in Payerne (Switzerland ...

ERα–PADI4–CXCL8 Axis Drives MDSC‐Mediated Immune Evasion in Anaplastic Thyroid Carcinoma

open access: yesAdvanced Science, EarlyView.
MAPK‐driven ligand‐independent ERα activation drives PADI4 transcription and translation. This enzyme then modifies CXCL8 chemokines through citrullination, generating a potent chemoattractant gradient specifically for myeloid‐derived suppressor cells.
