Here, a multiple modes metamaterial absorber with four peaks was proposed and verified. All absorption peaks were excited by the multiple modes coupling between adjacent unit cells. By increasing the structural parameter D, absorption peaks were strengthened and shifteded to the low-frequency region. When the lattice constant P was increased, these peaks were decreased and shifteded to the high-frequency region. Similarly, when the dielectric layer thickness t3 was gradually increased, these absorption peaks were weakened. Temperature was gradually increased, these absorption peaks were gradually reduced and shifteded to the high-frequency region. The multi-mode coupling effetct between unit cells was important to the performance of the metamaterial absorber. [ABSTRACT FROM AUTHOR]

AbstractDespite the growing number of cultural applications (apps), they still face challenges in inefficient cultural dissemination, necessitating user acceptance research. In this article, a conceptual cultural app acceptance model is proposed and tested in China (n = 351), using covariance-based structural equation modeling (CB-SEM). The results show that cultural identity (CI) has a significant impact on the perceived usefulness (PU) and the behavioral intention to use the app (BI). Aesthetics (AE) significantly influences CI, PU and perceived ease of use (PEOU) but does not affect BI. Additionally, PU and PEOU have a weak impact on BI. Demographic analysis found significant differences between different genders when examining CI and AE. There are also significant differences in CI, AE, PU, PEOU and BI with or without using experience-based criteria. Our findings can help to understand users’ needs and preferences for mobile cultural apps and to promote digital culture. [ABSTRACT FROM AUTHOR]

To identify the common inhibition types, the putative decision system is unsatisfactory. In a new decision system, Michaelis-Menten constants and maximal reaction rates were plotted versus inhibitor concentrations for deriving Kik and Kiv as the inhibition constants, respectively; their difference was quantified as the ratio of the larger one to the smaller one. Such ratios below 2.0 suggested uncompetitive inhibitors, over 5.0 suggested noncompetitive or competitive inhibitors, and from 2.0 to 5.0 suggested mixed inhibitors. By the new decision system, (i) the simulation recovery of uncompetitive inhibitors under CVs of 2% or 5% was improved by four times, but that of competitive or noncompetitive inhibitors was improved slightly; (ii) the recovery of L-phenylalanine as an uncompetitive inhibitor of intestinal alkaline phosphatase reached 38%, while the putative decision system lost all; the recovery of xanthine as a competitive inhibitor of uricase was improved slightly. Therefore, the new decision system was better. [ABSTRACT FROM AUTHOR]

AbstractThe Aesthetics Scale is one of the most commonly used aesthetics evaluation scale in HCI. In this study, a Chinese version of the Aesthetics Scale (C-AS) was translated and validated using the forward–backward translation method. The C-AS passed the content validity and face validity tests. We then recruited 310 Chinese users and tested the psychological properties of the C-AS using the China Railway Customer Service Center ticketing platform as the test material. The experimental results showed that the C-AS has high reliability, validity, and sensitivity. Following rigorous testing, the results of this work may provide Chinese UX practitioners with a standardized aesthetics scale that researchers and practitioners can use with confidence.
