Mood and emotion assessment for risk reduction of pandemic spread through passenger air transport: a DSS applied to the COVID‐19 in the case of Spain

International Transactions in Operational Research, Volume 32, Issue 4, Page 1918-1949, July 2025.
Abstract This paper presents a decision support system (DSS) for sentiment analysis of Spanish texts based on lexicons. The information provided by this DSS, named Spanish Sentiment Analysis‐DSS (SSA‐DSS), is employed to assess the social impacts considered in an external software module (RRPS‐PAT) centered on risk reduction of pandemic spread through ...

A decision support system for risk reduction in pandemic spread based on the management of passenger air traffic

International Transactions in Operational Research, Volume 32, Issue 4, Page 1893-1917, July 2025.
Abstract A significant factor in the early spread of pandemics at an international level is passenger air traffic. Decisions regarding passenger air traffic could assist different countries in managing the risk of pandemic importation. However, flight cancelations would have economic and social impacts, leading to a multiobjective optimization problem.

Exploring intra‐ and intergenomic variation in haplotype‐resolved pangenomes

Plant Biotechnology Journal, Volume 23, Issue 3, Page 874-886, March 2025.
Summary With advances in long‐read sequencing and assembly techniques, haplotype‐resolved (phased) genome assemblies are becoming more common, also in the field of plant genomics. Computational tools to effectively explore these phased genomes, particularly for polyploid genomes, are currently limited.
