RESEARCH SPOTLIGHT | PLM Researchers Secure International Publications
The Pamantasan ng Lungsod ng Maynila (PLM), through the Office of the Vice President for Research, Academic, and Extension Services (OVPRAES) and the University Research Center (URC), proudly recognizes the publication of two research papers in internationally indexed, peer-reviewed journals, ranked Q3 and Q1, respectively.
These achievements underscore the University's commitment to advancing research in allied health, artificial intelligence, biomedical engineering, and diagnostic technologies.
(1) MATHFI: A Multi-scale Adaptive Thresholding and Hierarchical Feature Integration Network for Retinal Vessel Segmentation and Quantitative Biomarker Analysis
Journal: Journal of Medical and Biological Engineering (Springer Nature)
Lead Student Authors: Michelle Tolentino and Stephen Lloyd Abenoja
Co-Authors and Advisors: Prof. Kuo-Sheng Cheng, Dr. Dan Michael Cortez, Dr. Ymir M. Garcia, and Jonathan Morano
Overview:
The study introduces an advanced deep-learning framework designed to improve retinal vessel segmentation, particularly in preserving thin vessels and enabling automated quantitative biomarker analysis.
DOI: https://doi.org/10.1007/s40846-026-01052-8
(2) RNNet-MST: A ResNet-50 with Multi-Scale Transformer Blocks for Pulmonary Nodule Classification and Attention-Based Localization on Chest X-Ray Images
Journal: Diagnostics (MDPI)
Lead Student Authors: Edrill F. Bilan and Emman T. Manduriaga
Co-Authors and Advisors: Dr. Hernando S. Salapare III, Prof. Wei-Ta Chu, Dr. Ymir M. Garcia, Dr. Dan Michael A. Cortez, Dr. Imelda C. Ang, Dr. Rose Anna R. Banal, and Dr. Khatalyn E. Mata
Overview:
The study proposes a hybrid architecture combining ResNet-50 with Multi-Scale Transformer blocks to enhance the early detection and precise localization of pulmonary nodules in chest X-ray images.
DOI: https://doi.org/10.3390/diagnostics16101574
These scholarly contributions were made possible through collaboration with partner institutions, including the National Cheng Kung University-College of Engineering (Taiwan), Mapúa University, and the French National Centre for Scientific Research (France), through the coordination of Dr. Hernando S. Salapare III, DOST-Balik Scientist, and Ms. Marie Antonette Macapagal (Linkages and Internationalization), OVPRAES.
The University commends the student researchers, faculty advisers, and international collaborators for their valuable contributions to global health informatics, biomedical research, and technological innovation.
