We review recent progress in the electronic structure study of intrinsic magnetic topological insulators（MnBi2Te4）·（Bi2Te3）n（n = 0, 1. 2, 3） family. Specifically, we focus on the ubiquitously（nearly）gapless behavior of the topological Dirac surface state observed by photoemission spectroscopy, even though a large Dirac gap is expected because of surface ferromagnetic order. The dichotomy between experiment and theory concerning this gap behavior is perhaps the most critical and puzzling question in this frontier. We discuss various proposals accounting for the lack of magnetic effect on the topological Dirac surface state, which are mainly categorized into two pictures, magnetic reconfiguration and topological surface state redistribution. Band engineering towards opening a magnetic gap of topological surface states provides great opportunities to realize quantized topological transport and axion electrodynamics at higher temperatures.

In-Ga-Zn-O(IGZO) channel based thin-film transistors(TFT), which exhibit high on-off current ratio and relatively high mobility, has been widely researched due to its back end of line(BEOL)-compatible potential for the next generation dynamic random access memory(DRAM) application. In this work, thermal atomic layer deposition(TALD) indium gallium zinc oxide(IGZO) technology was explored. It was found that the atomic composition and the physical properties of the IGZO films can be modulated by changing the sub-cycles number during atomic layer deposition(ALD) process. In addition, thin-film transistors(TFTs) with vertical channel-all-around(CAA) structure were realized to explore the influence of different IGZO films as channel layers on the performance of transistors. Our research demonstrates that TALD is crucial for high density integration technology, and the proposed vertical IGZO CAA-TFT provides a feasible path to break through the technical problems for the continuous scale of electronic equipment.

The Hakka people, a branch of the Han ethnic group with their own language, culture, and customs, are one of the largest immigrant groups worldwide, primarily distributed in southern China. Bobai, a county with the largest Hakka population globally, has a thriving weaving industry that is one of the local pillar industries. This study aimed to systematically analyze the plant source, product function, and development model of Bobai Hakka weaving. The study recorded 33 plant species for weaving, which belonged to 1. families and 27 genera. The weaving plants were mainly bamboo, rattan, herbs, and wood, with herbs being the most commonly used(1. species, 45.5%). Most weaving plants were obtained locally(1. species, 48.5%) and from wild sources(1. species, 39.4%). Stems were the most commonly used plant parts(66.7%) in local weaving, followed by leaf sheaths, inflorescence stems, leaves, stem bark, leaf rachis, and female bracts. Additionally, wastes from crops such as wheat, rice, bananas, and corn, as well as invasive water hyacinths, were widely used as weaving materials by the local Hakka people. The products 'functions ranged from household appliances, cultural and entertainment products, furniture, to production tools, reflecting a range of conventional cultural connotations. The study found that the Bobai Hakka weaving industry had integrated modern elements and additional use value to expand its market appeal. With the participation of the government, enterprises, and farmers, the Bobai weaving industry has formed a development model of “ intangible cultural heritage+industry+poverty alleviation ”, which has become a successful case of poverty alleviation and rural revitalization.

罗伯特·勃莱对老庄“虚静、朴素、隐逸”生命哲学和生活方式的深刻认同,致使他对当时美国盛行的物质主义生活方式采取了虚无态度,进而仿效老庄和中国古代隐逸诗人,将老庄“见素抱朴”的精神,落实在明尼苏达西部农村的幽居田园生活方式之中,成为山水田园的诗意栖居者。这种诗意的生活成为了他诗歌主要的抒写对象,由此构建了一个幽居恬淡的田园生活诗歌话语体系。从创作、生活和意识三个层面展现了勃莱对老庄“虚静”生命哲学和中国隐逸诗人生活方式及其诗歌审美价值取向的系统接受。

Background: The Luchuan pig is an indigenous breed from Luchuan County, China, with cultural and genetic significance. However, traditional knowledge and conservation status have not been systematically documented. Methods: Using ethnobiological methods, we surveyed 72 Luchuan pig farmers in 7 townships during 2021.2023. Semi-structured interviews and participant observation were conducted to document traditional knowledge and management practices. Results: The locals reported 51.plant species used as pig feed, with 30 wild species. Growth-stage-specific feeding and seasonal adjustment practices were documented. We recorded 62 ethnoveterinary plant uses, mainly for treating pigs ' heat stress and skin conditions. Luchuan pigs play central roles in local Hakka customs, rituals, and cuisine. Additionally, the new ecological farming models minimize the environmental impacts to the local community. However, there are still some challenges remained for conserving and promoting Luchuan pigs. Conclusions: The Luchuan Hakka people possess rich traditional knowledge and management experience in raising Luchuan pigs. Our study provides extensive documentation of traditional knowledge and recommends integrating cultural and genetic aspects for sustaining this biocultural heritage. Findings can inform initiatives supporting local breed conservation globally.
