Analysis in S-D Logic in Social Media Strategy in Cross-Border E-commerce

环球市场信息导报 2018年第2期 142-142页

作者：姜海妹不详

With the development of global economy and advancement of technology, the business model has been deeply evolved from goodscentered (G-D Logic) marketing in 1900s (Shaw, 1912) to a service-centered or service-dominant (S-D Logic) marketing in the 21st century (Vargo, Lusch,2006). According to “Evolving to a New Dominant Logic for Marketing” published in Journal of Marketing by Vargo and Lusch in 2004, the concept of S-D logic brought forward a new idea in marketing as “Increasingly, marketing has shifted much of its dominant logic away from the exchange of tangible goods (manufactured things) and toward the exchange of intangibles, specialized skills and knowledge, and processes, which we believe points marketing toward a more comprehensive and inclusive dominant logic, one that integrates goods with services and provides a richer foundation for the development of marketing thought and practice.”

Toward understanding the role of genomic repeat elements in neurodegenerative diseases

Neural Regeneration Research 2025年第3期20卷 646-659页

作者： Zhengyu An Aidi jiang Jingqi Chen Institute of Science and Technology for Brain-Inspired Intelligence Fudan UniversityShanghaiChina MOE Frontiers Center for Brain Science Fudan UniversityShanghaiChina MOE Key Laboratory of Computational Neuroscience and Brain-Inspired Intelligence Fudan UniversityShanghaiChina Zhangjiang Fudan International Innovation Center ShanghaiChina

Neurodegenerative diseases cause great medical and economic burdens for both patients and society;however, the complex molecular mechanisms thereof are not yet well understood. With the development of high-coverage sequencing technology, researchers have started to notice that genomic repeat regions, previously neglected in search of disease culprits, are active contributors to multiple neurodegenerative diseases. In this review, we describe the association between repeat element variants and multiple degenerative diseases through genome-wide association studies and targeted sequencing. We discuss the identification of disease-relevant repeat element variants, further powered by the advancement of long-read sequencing technologies and their related tools, and summarize recent findings in the molecular mechanisms of repeat element variants in brain degeneration, such as those causing transcriptional silencing or RNA-mediated gain of toxic function. Furthermore, we describe how in silico predictions using innovative computational models, such as deep learning language models, could enhance and accelerate our understanding of the functional impact of repeat element variants. Finally, we discuss future directions to advance current findings for a better understanding of neurodegenerative diseases and the clinical applications of genomic repeat elements.

No-go guide for the Hubble tension:Late-time or local-scale new physics

The standard model of modern cosmology might be cracked by the recent persistent hot debate on the Hubble-constant(H_(0))tension,which manifests itself as the sound-horizon(r_(s))tension or absolute-magnitude(M_(B))tension if deeming the origin of the Hubble tension from modifying the early or late Universe,*** this study,we achieve a fully model-independent constraint(fitting a model-independent global parameterization to a model-independent inverse distant ladder with a modelindependent high-redshift calibration)on late-time models with strong evidence against homogeneous new physics over theΛ-cold-dark-matter(ΛCDM)*** using this model-independent constraint to calibrate sufficiently local supernovae with corresponding late-time models extrapolated below the homogeneity scale,we find surprisingly that,although both H_(0)tension and MB tension are absent in our local Universe,a combination of H_(0)and M_(B)as the intercept a B of the magnitude-redshift relation exhibits 3~7σtension even for theΛCDM *** aBtension seems to call for local-scale inhomogeneous new physics disguised as local observational systematics.

Aqueous zinc-ion batteries(AZIBs)present a promising option for next-generation batteries given their high safety,eco-friendliness,and resource ***,the practical application of zinc anodes is hindered by inevitable parasitic reactions and dendrite ***,zinc alloy layers(i.e.,ZnCo and ZnFe alloys)were rationally constructed on the zinc surface by chemical displacement *** alloying process exposes more(002)planes of the ZnCo anode to guide the preferential and dendrite-free zinc ***,the ZnCo alloy layer not only effectively inhibits water-induced side reactions but also accelerates electrode kinetics,enabling highly reversible zinc plating/*** a result,the ZnCo anode achieves a Coulombic efficiency of 99.2%over 1300 cycles,and the ZnCo symmetric cell exhibits a long cycle life of over 2000 h at 4.4 mA cm^(-2).Importantly,the ZnCo//NH_(4)V_(4)O_(10)full cell retains a high discharge capacity of 218.4 mAh g^(-1)after 800 ***,the ZnFe-based symmetric cell also displays excellent cycling stability over 2500 h at 1.77 mA cm^(-2).This strategy provides a facile anode modification approach toward high-performance AZIBs.
