[SCIE]All-sky search for continuous gravitational waves from isolated neutron stars using Advanced LIGO and Advanced Virgo O3 data

R. Abbott et al.,김환선,배영복,오상훈,오정근,정필종 | Physical Review D | 2022

We present results of an all-sky search for continuous gravitational waves which can be produced by spinning neutron stars with an asymmetry around their rotation axis, using data from the third observing run of the Advanced LIGO and Advanced Virgo detectors.

[SCIE]Search for gravitational waves from Scorpius X-1 with a hidden Markov model in O3 LIGO data

R. Abbott et al. ,김환선,배영복,오상훈,오정근,정필종 | Physical Review D | 2022

Results are presented for a semicoherent search for continuous gravitational waves from the low-mass xray binary Scorpius X-1, using a hidden Markov model (HMM) to allow for spin wandering. This search improves on previous HMM-based searches of Laser Interferometer Gravitational-Wave Observatory data by including the orbital period in the search template grid, and by analyzing data from the latest (third) observing run.

[SCIE]Design Principles of Secure Certificateless Signature and Aggregate Signature Schemes for IoT Environments

심경아 | IEEE Access | 2022

In this paper, we first show that recently proposed five CLS and CLAS schemes are insecure against universal forgery attacks, type I attacks, type II attacks or malicious-but-passive-KGC attacks. We discuss their security flaws, causes and countermeasures. We then present design principles to prevent various algebraic attacks including our attacks. The design principles will help in the construction of secure CLS and CLAS schemes against the previous attacks and potential attacks.

[SCIE]Fractional model for Middle East respiratory syndrome coronavirus on a complex heterogeneous network

Bongsoo Jang,H.A. A. El-Saka,Ibrahim Obaya,이세연 | Scientific Reports | 2022

In this paper, we present a new fractional epidemiological model on a heterogeneous network to investigate Middle East respiratory syndrome (MERS-CoV), which is caused by a virus in the coronavirus family.

[SCIE]Exploring the efficiency of termite food transportation in a sinusoidal-shaped tunnel

Sang-Bin Lee,박철민,이상희 | ECOLOGICAL MODELLING | 2022

From an evolutionary perspective, it is inferred that termites evolved to build tunneling patterns in a way that optimizes search and transport efficiency. So far, there have been many studies on search efficiency, but few studies on transport efficiency due to the difficulty of direct observation under the field condition. To overcome the difficulty, we developed an individual-based model to simulate the transport process.

[SCIE]Characteristics of Peak and Cliff in Branch Length Similarity Entropy Profiles for Binary Time-Series and Their Application

박철민,이상희 | IEEE Access | 2022

A binary time series can be transformed into a Branch Length Similarity (BLS) entropy prole by being mapped to a circumference called a time-circle. In this study, we explored how peaks and cliffs are formed and how they relate to time series.

[SCIE]Prediction of Disorders with Significant Coronary Lesions Using Machine Learning in Patients Admitted with Chest Symptom

Jae Hoon Lee,Jae Young Choi,Yuri Choi,현윤경 | PLoS One | 2022

The early prediction of significant coronary artery lesion, including coronary vasospasm, have yet to be studied. It is essential to discern the disorders with significant coronary lesions (SCDs) requiring coronary angiography from mimicking disease. We aimed to determine which of all clinical variables were more important using conventional logistic regression (cLR) and machine learning (ML).

[SCIE]Emotion recognition while applying cosmetic cream using deep learning from EEG data; cross-subject analysis

Gusang Kwon,Youngkyung Kim,김지은,김환선,손재주,오상훈,황동욱 | PLoS One | 2022

We report a deep learning-based emotion recognition method using EEG data collected while applying cosmetic creams. Four creams with different textures were randomly applied, and they were divided into two classes, “like (positive)” and “dislike (negative)”, according to the preference score given by the subject. We extracted frequency features using wellknown frequency bands, i.e., alpha, beta and low and high gamma bands, and then we created a matrix including frequency and spatial information of the EEG data.

[SCIE]Search for continuous gravitational wave emission from the Milky?Way center in O3 LIGO-Virgo data

R. Abbott et al.,김환선,배영복,오상훈,오정근,정필종 | Physical Review D | 2022

We present a directed search for continuous gravitational wave (CW) signals emitted by spinning neutron stars located in the inner parsecs of the Galactic Center (GC). Compelling evidence for the presence of a numerous population of neutron stars has been reported in the literature, turning this region into a very interesting place to look for CWs.

[SCIE]Search for Subsolar-Mass Binaries in the First Half of Advanced LIGO’s and Advanced Virgo’s Third Observing Run

R. Abbott et al.,김환선,손재주,오상훈,오정근 | Physical Review Letters | 2022

We report on a search for compact binary coalescences where at least one binary component has a mass between 0.2 M⊙ and 1.0 M⊙ in Advanced LIGO and Advanced Virgo data collected between 1 April 2019 1500 UTC and 1 October 2019 1500 UTC.We extend our previous analyses in two main ways: we include data from the Virgo detector and we allow for more unequal mass systems, with mass ratio q ≥ 0.1. We do not report any gravitational-wave candidates.
