On the Abnormally Strong Westward Phase of the Mesospheric Semiannual Oscillation at Low Latitudes During March Equinox 2023

Geophysical Research Letters, Volume 51, Issue 16, 28 August 2024.
Abstract Different meteor radars at low latitudes observed abnormally strong westward mesospheric winds around the March Equinox of 2023, that is, during the first phase of the Mesospheric Semiannual Oscillation. This event was the strongest of at least the last decade (2014–2023).

An algebra for OLAP

Intelligent Data Analysis, 2017
Online Analytical Processing (OLAP) comprises tools and algorithms that allow querying multidimensional databases. It is based on the multidimensional model, where data can be seen as a cube, where each cell contains one or more measures can be aggregated along dimensions.

Clustering-Based Materialized View Selection in Data Warehouses

, 2006
Materialized view selection is a non-trivial task. Hence, its complexity must be reduced. A judicious choice of views must be cost-driven and influenced by the workload experienced by the system.

Datacubes as enabler for advanced decision support systems in land management

Land Degradation &Development, Volume 35, Issue 11, Page 3579-3592, 15 July 2024.
Abstract Informed, wise, land management has been a challenge since a long time, but has gained extra importance through the need for responding to climate change effects. The European Green Deal is one example of a concertation effort in a world where data availability, sharing options, and just‐in‐time exploitation are not entirely solved.

The ancestral karyotype of the Heliantheae Alliance, herbicide resistance, and human allergens: Insights from the genomes of common and giant ragweed

The Plant Genome, Volume 17, Issue 2, June 2024.
Abstract Ambrosia artemisiifolia and Ambrosia trifida (Asteraceae) are important pest species and the two greatest sources of aeroallergens globally. Here, we took advantage of a hybrid to simplify genome assembly and present chromosome‐level assemblies for both species.

Demeter: An automatic framework for data migration in open data lakes

Software: Practice and Experience, Volume 54, Issue 5, Page 721-743, May 2024.
Abstract An open data lake stores various forms and types of open data, and there is an increasing demand to manage raw data in tables rather than files for efficient data exploration and analysis. In this paper, we investigate the data management of open data lakes and recognize the limitations of table migration and related problems. First, open data
