Research on the Development Path of Rural Industry Revitalization by Non-Legacy of Folklore: Taking Chaoshan Meeting of p county in Linfen City as an Example

with the development of digital economy, the protection and inheritance of intangible cultural heritage has become an important issue to be solved. As an important part of Chinese traditional culture, non-heritage of folk-custom carries rich historical and cultural connotation and national spirit. However, with the changes of the times and the widening gap between urban and rural development, many non-heritage projects of folk-custom are facing the crisis of loss. As a folk celebration with profound historical and cultural background, Chaoshan meeting in p county of Linfen City, Shanxi province carries rich local cultural connotation. This paper aims to analyze the present situation of Chaoshan society in Linfen city, Shanxi Province, and discuss the development dilemma of micro-, middle-and macro-levels, and put forward a targeted development path to promote the revitalization of rural industries and inheritance of non-heritage protection work in-depth development

The Effects of Logos’ Frames on Consumers’ Psychological Perceptions and Brand Attitudes

This study examined the effects of the brand logo’s frames (complete vs. incomplete) on consumers’ perceptions and attitudes. There were 452 participants in two studies online. The results show that the brand logos with complete (vs. incomplete) frames have higher safety (in Study 1). Moreover, the logos’ frames of complete (vs. incomplete) brands will generate the positive brand attitudes through increasing the consumers’ psychological perception of safety. For products with high safety attributes, consumers will have a higher evaluation of the brand logos with the complete frames, but there is no effect for products with less important safety attributes (in Study 2). This paper provides some guidance for the research of consumers’ psychological perceptions, and also broadens the scope of application of the conceptual metaphor

Privacy-preserving Federated Primal-dual Learning for Non-convex and Non-smooth Problems with Model Sparsification

Federated learning (FL) has been recognized as a rapidly growing research area, where the model is trained over massively distributed clients under the orchestration of a parameter server (PS) without sharing clients' data. This paper delves into a class of federated problems characterized by non-convex and non-smooth loss functions, that are prevalent in FL applications but challenging to handle due to their intricate non-convexity and non-smoothness nature and the conflicting requirements on communication efficiency and privacy protection. In this paper, we propose a novel federated primal-dual algorithm with bidirectional model sparsification tailored for non-convex and non-smooth FL problems, and differential privacy is applied for strong privacy guarantee. Its unique insightful properties and some privacy and convergence analyses are also presented for the FL algorithm design guidelines. Extensive experiments on real-world data are conducted to demonstrate the effectiveness of the proposed algorithm and much superior performance than some state-of-the-art FL algorithms, together with the validation of all the analytical results and properties.Comment: 30 pages, 8 figure

Cloning and expression of pineapple sucrosephosphate synthase gene during fruit development

A 1132-base pairs (bp) polymerase-chain-reaction product of sucrose-phosphate synthase (SPS) (EC 2.3.1.14) from pineapple (Ananas comosus cv. Comte de paris) fruit was cloned and nominated as Ac- SPS1. The sequence encodes a putative 377 amino acids protein containing two serine conserved features that had been found in other plant SPS genes: the presence of a 14-3-3 protein special binding domain and an activated site of osmosis stress, which can been activated by phosphorylation and dephosphorylation. The Neighbour-joining tree revealed that Ac-SPS1 belonged to the first kind of sucrose phosphate synthase gene. The results indicated that, the Ac-SPS1 expression was low in the earlier period of fruit growth, then, increasing from 20 days after anthesis and gradually a falling on 40 days, reached the peak with the highest value around 70 days. The SPS activity and sucrose content reached their maximum 80 days after anthesis. It proved that the  accumulation of sucrose was correlated with SPS activity and mRNA content and it maximally occurred at 10 d after SPS mRNA and activity had reached its maxima. These results indicated that Ac-SPS1 gene played a key role in sucrose accumulation during the pineapple fruit development and transcriptional activation with increase in Ac- SPS1 expression might be important regulatory events of sugar during pineapple fruit maturation.Key words: Pineapple fruit, sucrose phosphate synthase, gene cloning, expression

Tailoring Intermolecular Interactions Towards High‐Performance Thermoelectric Ionogels at Low Humidity

Development of ionic thermoelectric (iTE) materials is of immense interest for efficient heat-to-electricity conversion due to their giant ionic Seebeck coefficient (Si), but challenges remain in terms of relatively small Si at low humidity, poor stretchability, and ambiguous interaction mechanism in ionogels. Herein, a novel ionogel is reported consisting of polyethylene oxide (PEO), polyethylene oxide-polypropylene oxide-polyethylene oxide (P123), and 1-ethyl-3-methylimidazolium acetate (Emim:OAC). By delicately designing the interactions between ions and polymers, the migration of anions is restricted due to their strong binding with the hydroxyl groups of polymers, while the transport of cations is facilitated through segmental motions due to the increased amorphous regions, thereby leading to enlarged diffusion difference between the cations and anions. Moreover, the plasticizing effect of P123 and Emim:OAC can increase the elongation at break. As a consequence, the ionogel exhibits excellent properties including high Si (18 mV K−1 at relative humidity of 60%), good ionic conductivity (1.1 mS cm−1), superior stretchability (787%), and high stability (over 80% retention after 600 h). These findings show a promising strategy to obtain multifunctional iTE materials by engineering the intermolecular interactions and demonstrate the great potential of ionogels for harvesting low-grade heat in human-comfortable humidity environments
