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

Graphene Aerogels With Spherical Pore Structure for Broad Frequency Regulation and Enhanced Low‐Frequency Response

open access: yesAdvanced Science, EarlyView.
A graphene aerogel with a spherical‐pore structure is constructed via microbubble templating. This unique architecture suppresses strain‐induced percolation of conductive networks, enabling dynamic frequency tuning. It also delivers enhanced low‐frequency absorption with an effective absorption bandwidth of 2.56 GHz, covering 91% of the low‐frequency ...

Nanozyme‐Reinforced miR‐197‐3p Delivery Resets Metabolic and Senescence Pathways to Rejuvenate Osteoarthritic Cartilage

open access: yesAdvanced Science, EarlyView.
ABSTRACT Osteoarthritis (OA) is a progressive and disabling joint disease driven by oxidative stress, chondrocyte senescence and extracellular matrix (ECM) degradation, yet lacks effective disease‐modifying treatments. In this study, we identified miR‐197‐3p as a previously unrecognized, cartilage‐protective miRNA significantly downregulated in both ...

Incorporation of Passive Microwave Brightness Temperatures in the ECMWF Soil Moisture Analysis [PDF]

open access: yesRemote Sensing, 2015
For more than a decade, the European Centre for Medium-Range Weather Forecasts (ECMWF) has used in-situ observations of 2 m temperature and 2 m relative humidity to operationally constrain the temporal evolution of model soil moisture. These observations are not available everywhere and they are indirectly linked to the state of the surface, so under ...

STATISTIC DISTRIBUTIONS OF MICROWAVE BRIGHTNESS TEMPERATURE OF SEA ICE IN THE MOS-1 AIRBORNE VERIFICATION EXPERIMENT [PDF]

open access: yes, 1987
P(論文)Microwave brightness temperatures of sea ice were observed off the coast of Monbetsu on January 25 in 1985 by the airborne 23- and 31-GHz microwave radiometers in the MOS-1 airborne verification experiment.

ANGPTL4 Exacerbates Renal Injury in Diabetic Kidney Disease by Impairing Podocyte Lipophagy via Compromised Lysosomal Degradative Function

open access: yesAdvanced Science, EarlyView.
In diabetic kidney disease, elevated podocyte ANGPTL4 is linked to reduced TFEB nuclear localization and compromised lysosomal degradative function. These changes impair podocyte lipophagy and promote lipid‐droplet accumulation and podocyte injury, which may contribute to renal injury progression.

Unraveling Hierarchical B‐Site Ordering: Mechanism of Microwave Dielectric Enhancement in Complex Perovskite Oxide Ceramics

open access: yesAdvanced Science, EarlyView.
This study maps out the hierarchical ordering in 1:2 B‐site complex perovskite ceramics using a comprehensive multiscale characterization route. It turns out that intradomain strain, oxygen vacancies, and Mg disorder within the ordered domains act as strong phonon scatterers.

Characteristics of L-band radio frequency interference detected via the soil moisture active passive radiometer in China and its offshore areas

open access: yesResults in Physics, 2019
Detection and mitigation of radio frequency interference (RFI) is one of the most crucial issues in microwave remote sensing measurements. This study analyzes the brightness temperature and RFI acquired by the soil moisture active passive (SMAP ...

Temporal Decoupling: A New Paradigm of 4D Photo‐Responsive Carbon Dots Films With Modular Regulation of Color and Deformation

open access: yesAdvanced Science, EarlyView.
This work demonstrates a novel energy regulation strategy using the long‐lived S₁ state as a “kinetic capacitor” to achieve temporally decoupled integration of photoinduced deformation and multicolor fluorescence in naphthalimide‐functionalized carbon dots. This dual‐channel programmable shunting of excited‐state energy establishes a dynamic single‐use
