THE IMPORTANCE OF PROVEN TREATMENT AS A VACCINE MODEL

The COVID-19 global pandemic has posed the biggest medical challenge of the past three years, and efforts to eradicate it have involved cross-border collaborations. Recent studies claim that the development and distribution of vaccines is an effective approach to end this infectious disease. However, this study demonstrates that a vaccine alone may not be enough due to differences in the rates of waning immunity induced by infection and vaccination. We propose that both vaccination and treatment are required to halt COVID-19 disease transmission and end the pandemic. From an epidemiological perspective, we employ the SVEIRS model by introducing vaccination and treatment into the compartmental epidemic model SIR. The experimental results suggest that the pandemic can be ended by performing both vaccination and treatment. However, the development and distribution of vaccines and treatments take time, and control measures must continue until the disease is completely eradicated.

A Search Using GEO600 for Gravitational Waves Coincident with Fast Radio Bursts from SGR 1935+2154

A. G. Abac et al.,오정근 | Astrophysical Journal | 2024

The magnetar SGR 1935+2154 is the only known Galactic source of fast radio bursts (FRBs). FRBs from SGR 1935+2154 were first detected by the Canadian Hydrogen Intensity Mapping Experiment (CHIME)/FRB and the Survey for Transient Astronomical Radio Emission 2 in 2020 April, after the conclusion of the LIGO, Virgo, and KAGRA Collaborations’ O3 observing run. Here, we analyze four periods of gravitational wave (GW) data from the GEO600 detector coincident with four periods of FRB activity detected by CHIME/FRB, as well as X-ray glitches and X-ray bursts detected by NICER and NuSTAR close to the time of one of the FRBs.

A novel indicator in epidemic monitoring through a case study of Ebola in West Africa (2014？2016)

The E/S (exposed/susceptible) ratio is analyzed in the SEIR model. The ratio plays a key role in understanding epidemic dynamics during the 2014？2016 Ebola outbreak in Sierra Leone and Guinea. The maximum value of the ratio occurs immediately before or after the time-dependent reproduction number ­(R t ) equals 1, depending on the initial susceptible population (S(0)).

A new perspective on shape and distribution:Branch Length Similarity entropy approach

박철민,이상희 | IEEE Access | 2024

This study introduces a fresh perspective on conventional notions of ‘‘shape’’ and ‘‘distribution’’ by utilizing the innovative framework of branch-length similarity (BLS) entropy. In our exploration of ‘‘shape,’’ we propose BLS entropy-based interpretations of circularity, elongation, and symmetry.
