NBI and NBI Combined with Magnifying Colonoscopy [PDF]

Diagnostic and Therapeutic Endoscopy, 2012
Although magnifying chromoendoscopy had been a reliable diagnostic tool, narrow-band imaging (NBI) has been developed in Japan since 1999 and has now replaced the major role of chromoendoscopy because of its convenience and simplicity. In this paper, we principally describe the efficacy of magnifying chromoendoscopy and magnifying colonoscopy with NBI ...

Diagnostic Concordance Using Japan Narrow-band Imaging Expert Team Classification for Diagnosing Colorectal Neoplasms: A Web-based Diagnostic Concordance Study. [PDF]

DEN Open
ABSTRACT Objectives The Japan Narrow‐band Imaging Expert Team (JNET) classification is widely used for magnified endoscopic diagnosis of colorectal neoplasms. However, its diagnostic concordance, particularly among the core members who contributed to its development, has not been sufficiently evaluated.

Narrow band imaging for the detection of gastric intestinal metaplasia and dysplasia during surveillance endoscopy [PDF]

, 2010
Background: Surveillance of premalignant gastric lesions relies mainly on random biopsy sampling. Narrow band imaging (NBI) may enhance the accuracy of endoscopic surveillance of intestinal metaplasia (IM) and dysplasia.

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.

Compressive narrowband interference detection and parameter estimation in direct sequence spread spectrum communication

IET Signal Processing, 2022
The Shannon‐Nyquist sampling theorem that is based on narrowband interference (NBI) detection and parameter estimation methods in direct sequence spread spectrum (DSSS) communication is limited by the high sampling rate.

On non-abelian generalisation of Born-Infeld action in string theory [PDF]

, 1997
We show that the part of the tree-level open string effective action for the non-abelian vector field which depends on the field strength but not on its covariant derivatives, is given by the symmetrised trace of the direct non-abelian generalisation of ...

Analysis of GFDM as a robust 5G communication technique in noisy environment [PDF]

, 2020
One of the challenges of modulation techniques used in Fifth-Generation (5G) is their robustness in noisy environment. Conventional Orthogonal Frequency Division Multiplexing (OFDM) cannot be considered as a 5G waveform in its original form because of ...

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 ...
