Three known lupane-triterpenes, 3a-hydroxy-lup-20(29)-en-23,28-dioic acid (1), 3$\alpha$-hydroxylup-20(29)-en-23,28-dioic acid 28-Ο-$\alpha$-L-rhamnopyranosyl-(1$\rightarrow4)-\beta-D-glucopyranosyl-(1\rightarow6)-\beta$-D-glucopyranosyl ester (acankoreoside A, 2) and $3\alpha$, $11\alpha$-dihydroxy-23-oxo-lup-20(29)-en-28-oic acid (3) were isolated from the leaves of Brassaiopsis glomerulata (Blume) Regel, a species of Araliaceae family growing in Vietnam. Their structures were determined on the basis of spectroscopic data.
Two New Phenylpropanoid Glycosides from the Stem Bark of Acanthopanax trifoliatus
Kiem, Phan-Van,Minh, Chau-Van,Dat, Nguyen-Tien,Cai, Xing-Fu,Lee, Jung-Joon,Kim, Young-Ho The Pharmaceutical Society of Korea 2003 Archives of Pharmacal Research Vol.26 No.12
Two new phenylpropanoid glycosides, 1-$\beta$-D-glucopyranosyl-2,6-dimethoxy-4-propenylphenol (1) and 1-[$\beta$-D-glucopyranosyl-(1$\rightarrow6)-\beta$-D-glucopyranosyl]-2,6-dimethoxy-4-propenylphenol (2) were isolated from the stem bark of Acanthopanax trifoliatus along with four known compounds (3∼6). Their structures were established on the basis of spectral and chemical evidences.

New Ceramide from Alocasia macrorrhiza
Tien, Nguyen Quyet,Ngoc, PhamHoang,Minh, Pham Hong,Kiem, Phan Van,Minh, Chau Van,Kim , Young-Ho The Pharmaceutical Society of Korea 2004 Archives of Pharmacal Research Vol.27 No.10
A new ceramide alomacrorrhiza A was isolated from the ethanolic extract of the plant Alocasia macrorrhiza (L.) Schott. Its chemical structure was elucidated as (2S,3S,4R)-2N-[(2'R)-2'- hydroxy-hexacosanoyl]-tetradecane-1,3,4-triol based on extensive 1D, 2D NMR, EI-MS, FABMS, HR-FAB-MS spectroscopic data and chemical degradation studies.
An efficient location-based pilot assignment in Cell-Free Massive MIMO
Nguyen Tien Hoa,Phan Lam Tung,Van Chien Trinh 한국통신학회 2023 ICT Express Vol.9 No.5
Cell-free Massive multiple-input multiple-output can offer many degrees of freedom for the high data rate and coverage probability. This network topology is one of the cutting-edge technologies potentially applied for next-generation wireless communications. In the canonical structure, however, each access point needs to accurately estimate the channel state information for the signal detection in the uplink and the precoding design in the downlink. Due to the finite lengths of coherence intervals, pilot contamination is one of the bottlenecks, reducing the data throughput of each user. We propose an efficient pilot assignment scheme called location-based pilot assignment (LPA) to overcome this limitation. It takes full advantage of the number of orthogonal pilot signals into account. The proposed algorithm divides the coverage area into smaller areas based on the number of users, where each area uses a subset of the pilot signals. Numerical results show that the proposed pilot assignment, LPA, offers good spectral efficiency to every users in the network with a tolerable computational complexity.
Gymnastone, A New Benzofuran Derivative from Gymnaster koraiensis
Dat, Nguyen-Tien,Kiem, Phan-Van,Cai, Xing-Fu,Shen, Quanghai,Bae, Ki-Hwan,Kim, Young-Ho The Pharmaceutical Society of Korea 2004 Archives of Pharmacal Research Vol.27 No.11
A new benzofuran derivative, named gymnastone [5-hydroxy-6-acetyl-2-(2-propane-1,2,3-triol)-benzofuran (1)], was isolated from the aerial part of Gymnaster koraiensis, together with viscidone (2) by repeated column chromatography. The structures of both compounds were identified by physico-chemical and spectral analysis including COSY, HMQC, and HMBC experiments.

One new C29 sterol with a cyclopropane ring at C-25 and C-26, aragusteroketal B (1), and aragusterol B (2) were isolated from the Vietnamese marine sponge Ianthella sp. Their structures were elucidated by extensive spectroscopic analyses. Both 1 and 2 showed moderate cytotoxic activity against MCF-7, SK-Hep-1, and HeLa cell lines with IC50 in the range of 12.8-27.8 μM.
