Improved partitioning technique for density cube-based spatio-temporal clustering method [PDF]

, 2022
This work proposes a novel partitioning technique on the density-cube-based data model for the Spatio-temporal clustering method. This work further adapts this clustering approach to Spatio-temporal data.

An Analysis of Cold Season Supercell Storms Using the Synthetic Dual-Doppler Technique

Monthly Weather Review, 2013
Abstract Cold season tornadic outbreaks occur with regularity in the southeastern United States; however, detailed analyses of parent supercell storms in the cold season environment (often low CAPE, high shear) are scarce. This is often because storms do not always move close enough to radars for a comprehensive single-Doppler analysis ...

Spatially localized dimensionality reduction for storm surge analysis: a Non-negative Matrix Factorization framework for imputation, bias correction, and surrogate modeling

Applied Ocean Research
Accurate characterization of storm surge hazards relies on high-fidelity hydrodynamic simulations and coastal sensor networks that together generate massive, high-dimensional datasets; yet these resources frequently suffer from incomplete spatial ...

Conversion of 10 min Rain Rate Time Series into 1 min Time Series: Theory, Experimental Results, and Application in Satellite Communications

Applied Sciences
We propose a semi-empirical method—based on a filtered Markov process—to convert 10 min rain rate time series into 1 min time series, i.e., quasi-instantaneous rainfall—the latter to be used as input to the synthetic storm technique, which is a very ...

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

A development of slant path rain attenuation statistic using synthetic storm technique [PDF]

, 2009
Frequencies above 10 Ghz has become primary interest nowadays in satellite communication. However, it can be easily distracted due to the rain. Basically the aim for this project is to develop a slant path rain attenuation using Synthetic storm Technique.

Encyclopedia of 2D β′‐In2Se3 Growth Using Chemical Vapor Deposition: The Effects of Synthesis Parameters Onto Material Quality

Advanced Engineering Materials, EarlyView.
A distinct semi‐confined inner‐tube chemical vapor deposition geometry enables reproducible, large‐area growth of phase‐pure 2D β′‐In2Se3 from InI + Se precursors. Engineering local vapor transport and optimizing precursor delivery and temperature–time conditions yield uniform continuous films.
