Published in 2024 at "Asia-Pacific Journal of Atmospheric Sciences"

DOI: 10.1007/s13143-024-00376-2

Abstract: The Korean Peninsula frequently experiences localized torrential rainfall (LTR) in the summer. However, on August 8, 2022, a peculiar LTR occurred by the continuous generation of convective clouds within a few hours, numerical weather prediction… read more here.

Published in 2024 at "Avian Pathology"

DOI: 10.1080/03079457.2024.2324930

Abstract: ABSTRACT Monitoring Marek’s disease (MD) vaccination is routinely done by evaluating the load of MD vaccine in the feather pulp (FP) between 7 and 10 days of age. However, attempts in our laboratory to detect… read more here.

Published in 2024 at "Genome Biology and Evolution"

DOI: 10.1093/gbe/evae193

Abstract: Abstract Transposable elements (TEs) are ubiquitous in the eukaryote genomes, but their evolutionary and functional significance remains largely obscure and contentious. Here, we explore the evolution and functional impact of TEs in two model unicellular… read more here.

Published in 2025 at "eLife"

DOI: 10.1101/2023.10.30.564869

Abstract: The imprinted ZDBF2 gene is controlled by oocyte-derived DNA methylation, but its epigenetic regulation is quite different from that of other canonically imprinted genes that are dependent on DNA methylation deposited in the gametes. At… read more here.

Published in 2020 at "mBio"

DOI: 10.1128/mbio.03424-19

Abstract: HIV-1 latency featuring silence of transcription from HIV-1 proviral DNA represents a major obstacle for HIV-1 eradication. Reversible repression of HIV-1 5′-LTR-mediated transcription represents the main mechanism for HIV-1 to maintain latency. The 5′-LTR-driven HIV… read more here.

Published in 2022 at "PLoS Computational Biology"

DOI: 10.1371/journal.pcbi.1010404

Abstract: Piwi-interacting RNAs (piRNAs) are regarded as drug targets and biomarkers for the diagnosis and therapy of diseases. However, biological experiments cost substantial time and resources, and the existing computational methods only focus on identifying missing… read more here.

Published in 2023 at "PLOS ONE"

DOI: 10.1371/journal.pone.0283574

Abstract: Despite their satisfactory performance, most existing listwise Learning-To-Rank (LTR) models do not consider the crucial issue of robustness. A data set can be contaminated in various ways, including human error in labeling or annotation, distributional… read more here.

Published in 2024 at "Viruses"

DOI: 10.3390/v16111801

Abstract: Homologous recombination events take place between the 5′ and 3′ long terminal repeats (LTRs) of ERVs, resulting in the generation of solo-LTR, which can cause solo-LTR-associated polymorphism across different genomes. In the current study, specific… read more here.
