Statistical Downscaling Method for Vegetation Optical Depth Based on NDVI

open access: yes应用气象学报
The microwave vegetation index, known as vegetation optical depth (VOD), is a dimensionless vegetation index.VOD is an important parameter for retrieving soil moisture and surface biomass.

Gastric antral vascular ectasia: A rare etiology of gastrointestinal bleeding in children

open access: yesJPGN Reports, EarlyView.
Abstract Gastrointestinal bleeding is relatively common in children. While most patients present with mild bleeding, gastric antral vascular ectasia (GAVE) is a rare but potentially life‐threatening cause. GAVE is typically associated with chronic conditions and more common in adults.

Assimilation of solar‐induced fluorescence satellite observations in the European Centre for Medium‐Range Weather Forecasts integrated forecast system

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This work demonstrates the potential of the assimilation of satellite solar‐induced fluorescence (SIF) retrievals at eight‐day and 0.1° resolutions in the integrated forecast system (IFS), developed at the European Centre for Medium‐Range Weather Forecasts (ECMWF), at global scale, to provide a more realistic representation of the vegetation temporal ...

Global Unsupervised Assessment of Multifrequency Vegetation Optical Depth Sensitivity to Vegetation Cover

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Vegetation optical depth (VOD) has contributed to monitor vegetation dynamics and carbon stocks at different microwave frequencies. Nevertheless, there is a need to determine which are the appropriate frequencies to monitor different vegetation types ...

Location‐Assisted Graph‐Based User Scheduling in Multi‐User MIMO LEO NTN Systems

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper addresses user clustering and scheduling for multi‐user MIMO low Earth orbit nonterrestrial network systems in full frequency reuse. Since the number of on‐ground user terminals is usually much higher than the number of on‐board LEO satellite antennas, user scheduling becomes a fundamental task.

A Thermodynamic‐Kinetic Model for Basic Oxygen Furnace Tapping: Improved Prediction of Phosphorus and Steel‐Slag Evolution

open access: yessteel research international, EarlyView.
This study develops a thermodynamic–kinetic model for basic oxygen furnace tapping and validates its accuracy under near‐equilibrium and far‐from‐equilibrium initial conditions. Comparison with a reference model demonstrates its broader applicability. The model further reveals the evolution of key steel and slag components, providing new transparency ...

Relationship between the occlusal vertical dimension and anthropometric measurements of the fingers.

open access: yesJournal of Oral Research, 2019
The alteration of the vertical dimension can deteriorate the facial harmony, and it can be measured through objective and subjective methods, although many of which are not reliable.

The Ammann–Kramer–Neri tiling model of a P‐ZnMgEr Bergman‐type quasicrystal based on in‐house X‐ray diffraction

open access: yesActa Crystallographica Section B, EarlyView.
A structural solution is presented of a primitive icosahedral ZnMgEr quasicrystal representing the Bergman‐type family. The structure model is based on atomic decoration of the Ammann–Kramer–Neri tiling.This study presents the atomic structure solution of a primitive icosahedral Zn70.83Mg20.31Er8.86 quasicrystal using in‐house X‐ray diffraction and the

Quantitative assessment of various proxies for downscaling coarse-resolution VOD products over the contiguous United States

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
Vegetation Optical Depth (VOD), a vegetation parameter that quantifies the extinction effect of microwaves penetrating the canopy, plays a crucial role in global-scale biomass monitoring and climate change research.
