Abstract For 5G beyond and/or 6G mobile services, a new spectrum at frequencies above 100 GHz has received great attention lately. To characterise the similarities and the differences between frequencies below 100 GHz and above 100 GHz, this paper pr

Owing to the difficulties associated with conducting millimeter‐wave (mmWave) field measurements, especially in high‐speed train (HST) environments, most propagation channels for mmWave HST have been studied using methods based on simulation rath

Measuring the diffraction loss for high frequencies, long distances, and large diffraction angles is difficult because of the high path loss. Securing a well‐controlled environment to avoid reflected waves also makes long‐range diffraction measur

Although many studies on bladder cancer and the microbiome have been conducted so far, useful strains at the species level have not yet been identified. In addition, in the case of urine studies, methodological heterogeneity is too great, and in tiss

Assuming omnidirectional antenna reception, the ITU‐R recently developed a new propagation model on building entry loss (BEL) for 5G millimeter‐wave frequency sharing and compatibility studies, which is a simplified outdoor‐to‐indoor path los

Most outdoor-to-indoor (O2I) propagation studies in millimeter-wave (mmWave) frequency bands have been focused on power loss characteristics such as building penetration and building entry losses. To provide robust traffic services, knowledge of the

To overcome considerable path loss in millimeter‐wave propagation, high‐gain directional beamforming is considered to be a key enabling technology for outdoor 5G mobile networks. Associated with beamforming, this paper investigates propagation po

Background: The mTOR signaling pathway is inactivated by AMPK’s tumor-suppressing function. It is recognized that ubiquitin conjugating enzyme 2O (UBE2O), which directly targets AMPK for ubiquitination and degradation, is intensified in human cance
