Multilevel model.

As video platforms such as Douyin, also known as TikTok’s Chinese version, continue to grow, there is an increasing interest in the study of green advertising videos to understand their audiovisual features and their impact on audience engagement. In this research, we specifically focus on green advertising within the automotive industry. Drawing on literature from sustainability, green advertising, and communication studies, we identified seven audiovisual aspects and three persuasive strategies pertinent to green automotive advertising videos. Utilizing a mixed-methods video analysis framework, we analyzed a dataset of 2,553 green automotive advertising videos on Douyin over three years from 15 June 2020 to 15 June 2023. These videos exhibited higher loudness, a faster pace, and longer durations compared to their non-green counterparts. We categorized three distinct types of green advertising videos on Douyin and established that specific audiovisual features and persuasive strategies are significantly correlated with audience engagement levels. This study not only delineates the audiovisual characteristics of green automotive advertising in China’s digital space but also contributes to the broader discourse on sustainable marketing practices on social networks like TikTok. The findings extend image-centric research to video content and provide marketers with data-driven insights for crafting effective content creation strategies on Douyin.</div

Critical Angle at a Moving Interface Formed by a Space-Time Modulation Step

This paper addresses the problem of wave scattering at a moving interface formed by a space-time modulation step. Specifically, it derives, using the technique of frame hopping with Lorentz transformation, the formula for the corresponding critical angle beyond which the transmitted field is evanescent. It shows that this angle is smaller (resp. larger) than $\pi/2$ (position of the interface) for a modulation that is codirectional (resp. contradirectional) to the direction of wave propagation, and that the critical angle versus the modulation velocity function monotonically decreases to zero at the velocity where the incident wave cannot catch up any more with the interface. The theory is illustrated and validated by full-wave FDTD simulation

Generalized FDTD Scheme for Moving Electromagnetic Structures with Arbitrary Space-Time Configurations

We present a generalized FDTD scheme to simulate moving electromagnetic structures with arbitrary space-time configurations. This scheme is a local adaptation and 2+1-dimensional extension of the uniform and 1+1-dimensional scheme recently reported in [1]. The local adaptation, which is allowed by the inherently matched nature of the generalized Yee cell to the conventional Yee cell, extends the range of applicability of the scheme in [1] to moving structures that involve multiple and arbitrary velocity profiles while being fully compatible with conventional absorbing boundary conditions and standard treatments of medium dispersion. We show that a direct application of the conventional FDTD scheme predicts qualitatively correct spectral transitions but quantitatively erroneous scattering amplitudes, we infer from this observation generalized, hybrid - physical and auxiliary (non-physical) - fields that automatically satisfy moving boundary conditions in the laboratory frame, and accordingly establish local update equations based on the related Maxwell's equations and constitutive relations. We finally validate and illustrate the proposed method by three canonical examples - a space-time interface, a space-time wedge and a space-time accelerated interface - whose combination represent arbitrary space-time configurations. The proposed scheme fills an important gap in the open literature on computational electromagnetics and offers an unprecedented, direct solution for moving structures in commercial software platforms

rHSA/FA-FITC complexes retain internalization and cytotoxic activity.

<p><b>A</b>). FITC-labeled rHSA (5 μM), <b>B</b>). rHSA/FA-FITC (5 μM/10 μM), and <b>C</b>). FA-FITC (10 μM) were added to SJSA-1 cells as described in <i>Methods</i>. Visualization at 60X magnification revealed efficient uptake of FITC-rHSA, rHSA/FA-FITC and FA-FITC occurred following 24-hour incubation. The extent of FITC staining observed in rHSA/FA-FITC-treated cells is similar to that of FA-FITC treatment alone indicating FA-FITC modification does not impair internalization of rHSA. <b>D</b>). rHSA/FA-FITC or rHSA/FA-FITC fusion protein complexes were added at a 1:2 molar ratio (rHSA:FA-FITC; 5 µM:10 µM) to SJSA-1 cells and allowed to incubate for 24 hrs. Nutlin (5 μM) was added in the presence of rHSA/FA-FITC to serve as a positive control. Cytotoxicities were measured by CyQuant Assay as described in <i>Methods</i>. Results are displayed as percent cell death relative to 5 μM rHSA/FA-FITC-treated wells. Data are representative of an experiment performed in triplicate. Error bars indicate ± SD.</p

Glutathione-Functionalized Magnetic Covalent Organic Framework Microspheres with Size Exclusion for Endogenous Glycopeptide Recognition in Human Saliva

Endogenous glycopeptides have been confirmed to play a significant role in multifarious pathological and physiological processes. The low abundance of endogenous glycopeptides and abundant interferents (e.g., large-size proteins and heteropeptides) in complex biological matrices render the direct analysis of endogenous glycopeptides difficult. Reported here is a novel glutathione-functionalized magnetic covalent organic framework microsphere (denoted as MCNC@COF@GSH) endowed with size-exclusion effect and strong hydrophilicity for selective and efficient enrichment of N-linked glycopeptides. The as-prepared MCNC@COF@GSH microspheres possessed fast magnetic responsiveness, regular porosity, large surface areas, and good hydrophilicity, resulting in remarkable performances in N-linked glycopeptide enrichment with low detection limit (0.01 fmol μL–1), high selectivity (1:5000, human immunoglobulin G (IgG) digests to bovine serum albumin digests), excellent size-exclusion effect (IgG digests/IgG/bovine serum albumin (BSA), 1:500:500), and reusability (at least five times). More excitingly, 143 endogenous N-linked glycopeptides were clearly identified from 10 μL sample of human saliva treated with the MCNC@COF@GSH microspheres, which is the unprecedented high efficiency in endogenous N-linked glycopeptide enrichment from human saliva. In addition to providing a strategy for versatile functionalization of magnetic covalent organic frameworks (COFs), this study may be used to develop application of endogenous glycoproteome analysis
