Published in 2021 at "Hepatology International"

DOI: 10.1007/s12072-021-10177-8

Abstract: Immune related cells are known to be closely related to the therapeutic effects and prognoses of cancer patients. In this study, we analyzed immune cell profiles (ICP) of cholangiocarcinoma patients (CCA). To measure the frequency… read more here.

Published in 2024 at "IEEE Transactions on Antennas and Propagation"

DOI: 10.1109/tap.2024.3463169

Abstract: This work presents a methodology for the direct combination of the field-based finite element method (FEM) with a current-based method, such as the method of moments (MoMs) or the physical optics (POs) method. The proposed… read more here.

Published in 2022 at "Liver International"

DOI: 10.1111/liv.15489

Abstract: Myeloid‐derived suppressor cells (MDSCs) and CD4+ regulatory T cells (Tregs) expand during chronic hepatitis B virus (HBV) infection and inhibit antiviral immunity. However, the relationship between antiviral effect and the frequencies of those immune suppressive… read more here.

Published in 2020 at "PLoS ONE"

DOI: 10.1371/journal.pone.0236749

Abstract: Each resident-type (R-type) killer whale pod has a set of stereotyped calls that are culturally transmitted from mother to offspring. The functions of particular call types are not yet clearly understood, but it is believed… read more here.

Published in 2018 at "Journal of Human Sport and Exercise"

DOI: 10.14198/jhse.2018.13.proc2.17

Abstract: This study analysed the time dedicated in the different phases of combat in all male weight divisions. For this, we analysed 548 combats. This time-motion analysis was performed through a previously-validated protocol. The main results… read more here.

Published in 2025 at "Risks"

DOI: 10.3390/risks13100190

Abstract: If intraday price data are unavailable, then using daily returns to construct realized measures of the variances of lower-frequency returns is a natural substitute for using high-frequency returns in this context. Notably, a suitable application… read more here.
