Low-magnification narrow-band imaging for small gastric neoplasm detection on screening endoscopy
VideoGIE, 2022 Background and Aims: Microsurface patterns of the gastric mucosa can be observed using magnifying narrow-band imaging (M-NBI). However, the efficacy of M-NBI at low-magnification (LM-NBI) screening for detecting small gastric neoplasms is unclear ...

Diagnostic limitations of magnifying endoscopy with narrow-band imaging in early gastric cancer
Endoscopy International Open, 2020 Background and study aims Magnifying endoscopy with narrow band imaging (M-NBI) has made a huge contribution to endoscopic diagnosis of early gastric cancer (EGC). However, we sometimes encountered false-negative cases with M-NBI diagnosis (i.

Comparison Study of Time Synchronization in NC-OFDM Systems Based on Symmetric Correlator
Jurnal Elektronika dan Telekomunikasi, 2019 NC-OFDM as one of the candidates for the Cognitive Radio (CR) system has many challenges in the synchronizing time. This is due to the frequency sharing which can cause Narrowband Interference (NBI), which causes a very significant time synchronization ...
