Comparison between Two-Dimensional and Point Shear Wave Elastography Techniques in Evaluating Liver Fibrosis Using Histological Staging as the Reference Standard: A Prospective Pilot Study

open access: yesDiagnostics, 2023
Evaluation of hepatic fibrosis is essential to prevent liver-related morbidity and mortality. Although various types of ultrasound shear wave elastography (SWE) have been used and validated, there are limited studies on the relatively newer technique ...

Iterative Frequency-Domain Response of Floating Offshore Wind Turbines with Parametric Drag

open access: yesJournal of Marine Science and Engineering, 2018
Methods for coupled aero-hydro-servo-elastic time-domain simulations of Floating Offshore Wind Turbines (FOWTs) have been successfully developed. One of the present challenges is a realistic approximation of the viscous drag of the wetted members of the ...

Reconstruction of a daily gridded snow water equivalent product for the land region above 45° N based on a ridge regression machine learning approach [PDF]

open access: yesEarth System Science Data, 2022
The snow water equivalent (SWE) is an important parameter of surface hydrological and climate systems, and it has a profound impact on Arctic amplification and climate change. However, there are great differences among existing SWE products.

Intercomparison of snow water equivalent products in the Sierra Nevada California using airborne snow observatory data and ground observations

open access: yesFrontiers in Earth Science, 2023
Whereas many independent methods are used to estimate snow water equivalent (SWE) and its spatial distribution and seasonal variability, a need exists for a systematic characterization of inter-model differences at annual, seasonal, and regional scales ...

Testing homogeneity, stationarity and trend in climatic series at Udaipur – a case study

open access: yesJournal of Agrometeorology, 2008
Three seasonal climatological time series, i.e., rainfall, minimum temperature, and maximum temperature of Udaipur in three seasons, i.e. summer, rainy and winter were tested for the presence of homogeneity, stationarity, and trend components.
