Abstract	With the dramatic progress of artificial intelligence algorithms in recent times, it is hoped that algorithms will soon supplant human decision-makers in various fields, such as contract design. We analyze the possible consequences by experimentally studying the behavior of algorithms powered by Artificial Intelligence (Multi-agent Q-learning) in a workhorse \emph{dual contract} model for dual-principal-agent problems. We find that the AI algorithms autonomously learn to design incentive-compatible contracts without external guidance or communication among themselves. We emphasize that the principal, powered by distinct AI algorithms, can play mixed-sum behavior such as collusion and competition. We find that the more intelligent principals tend to become cooperative, and the less intelligent principals are endogenizing myopia and tend to become competitive. Under the optimal contract, the lower contract incentive to the agent is sustained by collusive strategies between the principals. This finding is robust to principal heterogeneity, changes in the number of players involved in the contract, and various forms of uncertainty.

Abstract	To improve the difficulty in wearing and uncomfortable pressure of the sports bra, shape memory polyurethane filaments (SMPUFs) were used to prepare seamless sports bras in this study. Five fabric samples with different stitch structures and yarn were prepared. Then shape memory sports bras were designed based on the properties of the different fabric samples and female body characteristics. SMPUFs were characterized by differential scanning calorimetry for the thermal properties. Shape memory properties and mechanical properties of the SMPUFs, covered yarn and fabric samples were measured. Besides this, the moisture absorbency, permeability and thermal resistance of fabrics were tested. A pressure test system was set up and the pressure of the sports bras was investigated at different temperatures. The results showed that the transition temperature (Tₜᵣₐₙₛ) of the SMPUF was 27.33°C, which could be triggered by human skin temperature. The best shape fixity ratio of the fabric sample was 82.5% and the shape recovery ratio was 94.4%. The comfortable pressure of the shape memory sports bra at the mean human skin temperature of 34°C was 1.6–5.6 kPa.

Abstract	ATP-binding cassette transporter subfamily G member 2 (ABCG2) is a membrane-bound transporter responsible for the efflux of various xenobiotics and endobiotics, including protoporphyrin IX (PPIX), an intermediate in the heme biosynthesis pathway. Certain genetic mutations and chemicals impair the conversion of PPIX to heme and/or increase PPIX production, leading to PPIX accumulation and toxicity. In mice, deficiency of ABCG2 protects against PPIX-mediated phototoxicity and hepatotoxicity by modulating PPIX distribution. In addition, in vitro studies revealed that ABCG2 inhibition increases the efficacy of PPIX-based photodynamic therapy by retaining PPIX inside target cells. In this review, we discuss the roles of ABCG2 in modulating the tissue distribution of PPIX, PPIX-mediated toxicity, and PPIX-based photodynamic therapy.

Abstract	Infrared and visible image fusion methods based on feature decomposition are able to generate good fused images. However, most of them employ manually designed simple feature fusion strategies in the reconstruction stage, such as addition or concatenation fusion strategies. These strategies do not pay attention to the relative importance between different features and thus may suffer from issues such as low-contrast, blurring results or information loss. To address this problem, we designed an adaptive fusion network to synthesize decoupled common structural features and distinct modal features under an attention-based adaptive fusion (AAF) strategy. The AAF module adaptively computes different weights assigned to different features according to their relative importance. Moreover, the structural features from different sources are also synthesized under the AAF strategy before reconstruction, to provide a more entire structure information. More important features are thus paid more attention to automatically and advantageous information contained in these features manifests itself more reasonably in the final fused images. Experiments on several datasets demonstrated an obvious improvement of image fusion quality using our method.

Abstract	As an important tool for supervisors to intervene subordinates' work and influence their performance, supervisor feedback has gradually become a new academic research hotspot. In this study, we build and verify a theoretical model to explore the different effects of supervisor positive and negative feedback on subordinate in-role and extra-role performance, and the moderating role of regulatory focus in these relationships. With data from pairing samples of 403 Chinese employees and their direct supervisors, the results indicate that supervisor positive feedback is positively related to subordinate in-role and extra-role performance. Supervisor negative feedback is positively related to subordinate in-role performance and negatively related to subordinate extra-role performance. Regulatory focus of subordinate can moderate the influence of supervisor positive feedback on subordinate in-role and extra-role performance, but it cannot moderate the influence of supervisor negative feedback on subordinate in-role and extra-role performance. That means when subordinates have promotion focus, the influence of supervisor positive feedback on their in-role performance and extra-role performance was stronger than those with prevention focus. These results further enrich the research on the relationship between supervisor feedback and subordinate performance, especially the different effects of positive and negative feedback from supervisor on subordinate with different regulatory focus. All conclusions from the analyses above not only further verify and develop some previous points on supervisor feedback and subordinate performance, but also derive certain management implications for promoting subordinate in-role and extra-role performance from the perspective of supervisor positive and negative feedback.

Abstract	Human resources are the core resources of an enterprise, and the demand forecasting plays a vital role in the allocation and optimization of human resources. Starting from the basic concepts of human resource forecasting, this paper employs the backpropagation neural network (BPNN) and radial basis function neural network (RBFNN) to analyze human resource needs and determine the key elements of the company's human resource allocation through predictive models. With historical data as reference, the forecast value of current human resource demand is obtained through the two types of neural networks. Based on the prediction results, the company managers can carry out targeted human resource planning and allocation to improve the efficiency of enterprise operations. In the experiment, the actual human resource data of a certain company are used as the experimental basic samples to train and test the two types of machine learning tools. The experimental results show that the method proposed in this paper can effectively predict the number of personnel required and can support the planning and allocation of human resources.

Abstract	We develop a model of coordination and allocation of decentralized multi-sided markets, in which our theoretical analysis is promisingly optimizing the decentralized transaction packaging process at high-throughput blockchains or Web 3.0 platforms. In contrast to the stylized centralized platform, the decentralized platform is powered by blockchain technology, which allows for secure and transparent Peer-to-Peer transactions among users. Traditional single-chain-based blockchains suffer from the well-known blockchain trilemma. Beyond the single-chain-based scheme, decentralized high-throughput blockchains adopt parallel protocols to reconcile the blockchain trilemma, implementing any tasking and desired allocation. However, unneglectable network latency may induce partial observability, resulting in incoordination and misallocation issues for the decentralized transaction packaging process at the current high-throughput blockchain protocols. To address this problem, we consider a strategic coordination mechanism for the decentralized transaction packaging process by using a game-theoretic approach. Under a tractable two-period model, we find a Bayesian Nash equilibrium of the miner's strategic transaction packaging under partial observability. Along with novel algorithms for computing equilibrium payoffs, we show that the decentralized platform can achieve an efficient and stable market outcome. The model also highlights that the proposed mechanism can endogenously offer a base fee per gas without any restructuration of the initial blockchain transaction fee mechanism. The theoretical results that underlie the algorithms also imply bounds on the computational complexity of equilibrium payoffs.

Article ; Online: Spatiotemporal distributions and oceanic emissions of short-lived halocarbons in the East China Sea

Qi, Qian-Qian / Yang, Gui-Peng / Yang, Bin / He, Zhen

Science of the Total Environment. 2023 Oct., v. 893 p.164879-

2023

Abstract	Coastal waters are important sources of volatile halocarbons, which are important in atmospheric chemistry. Here, in May (spring) and October (autumn) 2020, we studied the surface, bottom, and sediment-pore seawater concentrations, atmospheric mixing ratios, and sea-to-air fluxes of the three primary short-lived atmospheric halocarbons (CH₃I, CH₂Br₂, and CHBr₃) in the East China Sea (ECS). The highest concentrations of the three short-lived halocarbons occurred in coastal waters, such as the Changjiang estuary and Zhejiang coastal waters, reflecting the influence of excessive anthropogenic inputs on the distributions of these gases. Interestingly, the aqueous levels of these gases seemed to be lower compared to previous measurements in this oceanic region, probably due to reduced contributions from local anthropogenic emission sources. The concentrations of CH₃I, CH₂Br₂, and CHBr₃ in pore water were significantly higher than those in bottom water, suggesting that sediment could be a source of these short-lived halocarbons. Additionally, the atmospheric mixing ratios of these gases occasionally increased in coastal areas. An air-mass back trajectory analysis showed this was due to continental anthropogenic sources and emissions from enriched waters. The atmospheric mixing ratios of these halocarbons exhibited significant seasonal variability, with significant correlations among atmospheric CH₃I, CH₂Br₂, and CHBr₃ in spring, but not in autumn. The sea-to-air fluxes of CH₃I, CH₂Br₂, and CHBr₃ indicated that the ECS is a source of these gases. Seasonal differences in CH₃I and CH₂Br₂ fluxes were driven by changes in wind speed and sea surface temperature, while CHBr₃ flux changes were associated with changes in its surface seawater concentration.
