Directional transmission of acoustic wave based on sector-shaped structure by Wentao Cai, Xinsa Zhao, Guodong Hao, Jianning Han

“…In this paper, three kinds of protocell models were constructed by modulating the steering using a sector structure of the same size, and the artificial acoustic periodic structure was obtained by the array protocell model. At a specific incident frequency, although there are a large number of scatterers, the sound waves do not scatter randomly but can be transmitted directionally along a pre-designed channel, thus achieving the quantum spin Hall effect in acoustics. …”

Advancement in tumor treating fields of mechanism, clinical applications, and future directions by Meiqi Zang, Song Zhu, Qiang Niu

“…Abstract Traditional cancer treatment modalities, such as surgical interventions, radiotherapy, and chemotherapy, persist as the cornerstone of standard care across a wide array of clinical settings. Despite their established effectiveness in combating cancer, these therapies are inherently invasive in nature and have great side effects, which seriously affect the quality of life of patients. …”

Impact of Display Pixel–Aperture Ratio on Perceived Roughness, Glossiness, and Transparency by Kosei Aketagawa, Midori Tanaka, Takahiko Horiuchi

“…A visual evaluation experiment was conducted using natural images presented on stimuli with pixel–aperture ratios of 100% and 6%, employing an RGB sub-pixel array. The results demonstrated that the pixel–aperture ratio significantly affects the perception of glossiness and transparency, with the 100% pixel–aperture ratio producing a statistically significant effect compared to the 6% condition. …”

Neural mechanisms by which attention modulates the comparison of remembered and perceptual representations. by Bo-Cheng Kuo, Duncan E Astle

“…Spatial cues were presented to orient their attention either to the location of an item in VSTM prior to its comparison (retro-cues), or simultaneously (simultaneous-cues) with the probe array. A no-cue condition was also included. When attention cannot be effectively deployed in advance (i.e. following the simultaneous-cues), we observed a distributed and extensive activation pattern in the prefrontal and parietal cortices in support of successful change detection. …”
